Benefits of Incentives for Breastfeeding and Smoking cessation in pregnancy (BIBS): a mixed-methods study to inform trial design

Factors influencing midwives' conversations about smoking and referral to specialist support: a qualitative study informed by the Theoretical Domains Framework

AIMS

The aim of this study was to identify factors influencing midwives' conversations about smoking, and referral to specialist smoking cessation services, using an evidence-based theoretical framework.

METHODS

Semi-structured, qualitative interviews were undertaken with community midwives employed within one health board region of Wales. Deductive framework analysis was employed by coding data to the domains of the Theoretical Domains Framework (TDF) and then identifying themes within domains and across participants.

RESULTS

Seven midwives took part in the study. 13, out of a possible 14 domains, were mapped from the TDF. Key enablers to conversations and referrals include knowledge of the risks of smoking in pregnancy, congruence with the professional identity of a midwife, and the use of carbon monoxide monitors in initiating conversations and referrals. Limited knowledge of the specialist service, confusion about the opt-out pathway, varied skills in communicating and engaging with women, low confidence in ability to influence women's decisions, limited appointment times, and competing priorities were identified as barriers.

CONCLUSION

Midwives recognise the importance of their role within the provision of smoking cessation advice and referral to specialist services. While there are continued time pressures and competing priorities for midwives, enhancing skills and confidence in collaborative, empowering approaches to addressing smoking would further support in optimising the uptake of maternity smoking cessation support. This could also enhance conversations about other public health issues such diet, physical activity, and alcohol use.

Attitudes of mothers and health care providers towards behavioural interventions promoting breastfeeding uptake: A systematic review of qualitative and mixed-method studies

PURPOSE

Recommendations for exclusive breastfeeding are not often adhered to despite the robust evidence of its benefits. This systematic review aims to collate evidence on the attitudes mothers and health care providers have towards breastfeeding interventions to understand what aspects best contribute to acceptability and feasibility.

METHODS

This review further investigates the value of identifiable behaviour change techniques (BCTs) to uncover which components of an intervention are perceived to be most useful and acceptable. The main biomedical databases were searched, and 17 (n = 17) studies met the inclusion criteria.

RESULTS

A total of nine BCTs were identified within the interventions. The thematic analysis produced four main domains: usefulness, accessibility, value and sustainability. Women discussed the importance of the support they received in these interventions and demonstrated a positive view towards three BCTs: 'social support (unspecified)', 'instruction on how to perform behaviour' and 'demonstration of behaviour'. Additionally, women highlighted the benefit of personal, non-clinical and flexible emotional and practical support from peers, lactation consultants and support groups. Health care providers echoed these opinions and specifically highlighted the usefulness of interventions that allowed for continuity of care and more personal breastfeeding support.

CONCLUSIONS

These findings suggest that ongoing practical as well as emotional support is crucial for standard in-hospital support to succeed at increasing breastfeeding rates. Future research would need to better understand the nuances of the interventions among women and providers to enhance their implementation.

Financial incentives for quitting smoking in pregnancy: Are they cost-effective?

AIMS

To evaluate whether adding financial incentives to usual care is cost-effective in encouraging pregnant women to quit tobacco smoking, compared with usual care alone.

DESIGN

Cost-effectiveness analysis (CEA) and cost-utility analysis (CUA) from a health-care provider's perspective, embedded in the Smoking Cessation in Pregnancy Incentives Trial (CPIT III). Long-term analyses were conducted from the same perspective, using an existing Markov model over a life-time horizon.

SETTING

Seven maternity smoking cessation sites in Scotland, England and Northern Ireland in the United Kingdom.

PARTICIPANTS

In the short-term analysis, CPIT III participants were assessed: women 16 years or older, self-reporting as smokers, fewer than 24 weeks pregnant and English-speaking (n = 944). The same population was used for the life-time analysis, plus their infants.

MEASUREMENTS

Costs included financial incentive vouchers and postage, cessation support and nicotine replacement therapy and neonatal stays. The outcome measure was a biochemically verified quit rate for the CEA and quality-adjusted life-years (QALYs) for CUA. Costs are presented in 2020 GBP sterling (£). Data for the life-time analysis came from the trial and were combined with data from published literature embedded in the model, reporting incremental cost per quitter and QALY. A 3.5% discount rate was applied.

FINDINGS

The short-term incremental cost per quitter was £4400 and cost per QALY was £150 000. Results of sensitivity analyses confirmed these results. The long-term analysis combined costs and outcomes for mother and infants; results showed a cost saving of £37 [95% confidence interval (CI]) = £35-106] and increase in QALYs of 0.171 (95% CI = 0.124-0.229). These findings indicate that, over a life-time, financial incentives are cost-saving and improve health outcomes.

CONCLUSIONS

In the United Kingdom, offering up to £400 financial incentives, in addition to usual care, to support pregnant women to stop smoking appears to be highly cost-effective over a life-time for mother and infants.

Usual care in a multicentre randomised controlled trial of financial incentives for smoking cessation in pregnancy: qualitative findings from a mixed-methods process evaluation

OBJECTIVES

Financial incentives are recommended by the UK's National Institute for Health and Care Excellence to aid smoking cessation in pregnancy. However, little is known about how implementation contexts might impact on their effectiveness. Variations in smoking cessation support (usual care) for pregnant women who smoke were examined qualitatively as part of a prospective process evaluation of the Cessation in Pregnancy Incentives Trial (CPIT III).

DESIGN

Longitudinal case studies of five CPIT III trial sites informed by realist evaluation.

SETTING

A stop smoking service (SSS) serving a maternity hospital constituted each case study, located in three UK countries.

PARTICIPANTS

Data collection included semistructured interviews with trial participants (n=22), maternity (n=12) and SSS staff (n=17); and site observations and perspectives recorded in fieldnotes (n=85).

RESULTS

Cessation support (usual care) for pregnant women varied in amount, location, staff capacity, flexibility and content across sites. SSS staff capacity was important to avoid gaps in support. Colocation and good working relationships between maternity and SSS professionals enabled prioritisation and reinforced the importance of smoking cessation. Sites with limited use of carbon monoxide (CO) monitoring reduced opportunities to identify smokers while inconsistency around automatic referral processes prevented the offer of cessation support. SSS professionals colocated within antenatal clinics were available to women they could not otherwise reach. Flexibility around location, timing and tailoring of approaches for support, facilitated initial and sustained engagement and reduced the burden on women.

CONCLUSIONS

Trial sites faced varied barriers and facilitators to delivering cessation support, reflecting heterogeneity in usual care. If financial incentives are more effective with concurrent smoking cessation support, sites with fewer barriers and more facilitators regarding this support would be expected to have more promising trial outcomes. Future reporting of trial outcomes will assist in understanding incentives' generalisability across a wide range of usual care settings.

Supporting pregnant women not ready to quit smoking: an economic evaluation

OBJECTIVES

Some pregnant women are not ready or do not want to quit smoking completely, and currently there is no support provided for these women in the UK. Offering help to reduce smoking could reduce the health risks associated with smoking and increase the limited reach of the NHS Stop Smoking Services (SSS) for pregnant women. This study aimed to design and evaluate a hypothetical intervention aimed at pregnant women who are not yet ready or do not want to quit smoking entirely.

METHODS

A hypothetical intervention, the Reduced Smoking During Pregnancy (RSDP) intervention, was conceptualised based on the best available evidence. The intervention was evaluated, using a decision-analytic model developed for SDP interventions. Two different scenarios, a base-case and a cautious-case were developed, and a cost-utility analysis and return on investment analysis were conducted. The uncertainty around the estimates was assessed, using deterministic and probabilistic sensitivity analyses.

RESULTS

The RSDP intervention could prevent the loss of 13 foetuses and generate 43 quitters 1 year after delivery per 1000 women. In the lifetime analysis, the intervention was cost-effective in both scenarios, with an incremental cost of £363 (95% CI £29 to £672) and 0.44 (95% CI 0.32 to 0.53) QALYs gained in the base-case.

CONCLUSIONS

The study found that the hypothetical reduction intervention would produce significant health benefits, reduce smoking and be cost-effective. Offering pregnant smokers help to reduce smoking could reduce health inequalities, widen the reach of SSS and improve health. This economic evaluation of a novel, intensive intervention could inform the piloting of such interventions.

Effect of financial voucher incentives provided with UK stop smoking services on the cessation of smoking in pregnant women (CPIT III): pragmatic, multicentre, single blinded, phase 3, randomised controlled trial

OBJECTIVE

To examine effectiveness, cost effectiveness, generalisability, and acceptability of financial incentives for smoking cessation during pregnancy in addition to variously organised UK stop smoking services.

DESIGN

Pragmatic, multicentre, single blinded, phase 3, randomised controlled trial (Cessation in Pregnancy Incentives Trial phase 3 (CPIT III)).

SETTING

Seven UK stop smoking services provided in primary and secondary care facilities in Scotland, Northern Ireland, and England.

PARTICIPANTS

944 pregnant women (age ≥16 years) who self-reported as being smokers (at least one cigarette in the past week) when asked at first maternity visit, less than 24 weeks' gestation, and notified to the trial team by routine stop smoking services.

INTERVENTIONS

Participants in the control group were offered the standard stop smoking services, which includes the offer of counselling by specially trained workers using withdrawal orientated therapy and the offer of free nicotine replacement therapy. The intervention was the offer of usual support from the stop smoking services and the addition of up to £400 ($440; €455) of LoveToShop financial voucher incentives for engaging with current stop smoking services or to stop smoking, or both, during pregnancy.

MAIN OUTCOME MEASURES

Self-reported smoking cessation in late pregnancy (between 34 and 38 weeks' gestation) corroborated by saliva cotinine (and anabasine if using nicotine replacement products). Results were adjusted for age, smoking years, index of multiple deprivation, Fagerström score, before or after covid, and recruitment site. Secondary outcomes included point and continuous abstinence six months after expected date of delivery, engagement with stop smoking services, biochemically validated abstinence from smoking at four weeks after stop smoking date, birth weight of baby, cost effectiveness, generalisability documenting formats of stop smoking services, and acceptability to pregnant women and their carers.

RESULTS

From 9 January 2018 to 4 April 2020, of 4032 women screened by stop smoking services, 944 people were randomly assigned to the intervention group (n=471) or the control group (n=470). Three people asked for their data to be removed. 126 (27%) of 471 participants stopped smoking from the intervention group and 58 (12%) of 470 from the control group (adjusted odds ratio 2.78 (1.94 to 3.97) P<0.001). Serious adverse events were miscarriages and other expected pregnancy events requiring hospital admission; all serious adverse events were unrelated to the intervention. Most people who stopped smoking from both groups relapsed after their baby was born.

CONCLUSIONS

The offer of up to £400 of financial voucher incentives to stop smoking during pregnancy as an addition to current UK stop smoking services is highly effective. This bolt-on intervention supports new guidance from the UK National Institute for Health and Care Excellence, which includes the addition of financial incentives to support pregnant women to stop smoking. Continuing incentives to 12 months after birth is being examined to prevent relapse.

Towards optimum smoking cessation interventions during pregnancy: a household model to explore cost-effectiveness

BACKGROUND AND AIMS

Previous economic evaluations of smoking cessation interventions for pregnant women are limited to single components, which do not in isolation offer sufficient potential impact to address smoking cessation targets. To inform the development of more appropriate complex interventions, we (1) describe the development of the Economics of Smoking in Pregnancy: Household (ESIP.H) model for estimating the life-time cost-effectiveness of smoking cessation interventions aimed at pregnant women and (2) use a hypothetical case study to demonstrate how ESIP.H can be used to identify the characteristics of optimum smoking cessation interventions.

METHODS

The hypothetical intervention was based on current evidence relating to component elements, including financial incentives, partner smoking, intensive behaviour change support, cigarettes consumption and duration of support to 12 months post-partum. ESIP.H was developed to assess the life-time health and cost impacts of multi-component interventions compared with standard National Health Service (NHS) care in England. ESIP.H considers cigarette consumption, partner smoking and some health conditions (e.g. obesity) that were not included in previous models. The Markov model's parameters were estimated based on published literature, expert judgement and evidence-based assumptions. The hypothetical intervention was evaluated from an NHS perspective.

RESULTS

The hypothetical intervention was associated with an incremental gain in quitters (mother and partner) at 12 months postpartum of 249 [95% confidence interval (CI) = 195-304] per 1000 pregnant smokers. Over the long-term, it had an incremental negative cost of £193 (CI = -£779 to 344) and it improved health, with a 0.50 (CI = 0.36-0.69) increase in quality-adjusted life years (QALYs) for mothers, partners and offspring, with a 100% probability of being cost-effective.

CONCLUSIONS

The Economics of Smoking in Pregnancy: Household model for estimating cost-effectiveness of smoking cessation interventions aimed at pregnant women found that a hypothetical smoking cessation intervention would greatly extend reach, reduce smoking and be cost-effective.

The Application of Preference Elicitation Methods in Clinical Trial Design to Quantify Trade-Offs: A Scoping Review

BACKGROUND AND OBJECTIVE

Patients can express preferences for different treatment options in a healthcare context, and these can be measured with quantitative preference elicitation methods.

OBJECTIVE

Our objective was to conduct a scoping review to determine how preference elicitation methods have been used in the design of clinical trials.

METHODS

We conducted a scoping review to identify primary research studies, involving any health condition, that used quantitative preference elicitation methods, including direct utility-based approaches, and stated preference studies, to value health trade-offs in the context of clinical trial design. Studies were identified by screening existing systematic and scoping reviews and with a primary literature search in MEDLINE from 2010 to the present. We extracted study characteristics and the application of preference elicitation methods to clinical trial design according to the SPIRIT checklist from primary studies and summarized the findings descriptively.

RESULTS

We identified 18 eligible studies. The included studies applied patient preferences to five areas of clinical trial design: intervention selection (n = 1), designing N-of-1 trials (n = 1), outcome selection and weighting composite and ordinal outcomes (n = 12), sample size calculations (n = 2), and recruitment (n = 2). Using preference elicitation methods led to different decisions being made, such as using preference-weighted composite outcomes instead of equally weighted composite outcomes.

CONCLUSION

Preference elicitation methods are infrequently used to design clinical trials but may lead to changes throughout the trial that could affect the evidence generated. Future work should consider measurement challenges and explore stakeholder perceptions.

Study protocol for reducing disparity in receipt of mother's own milk in very low birth weight infants (ReDiMOM): a randomized trial to improve adherence to sustained maternal breast pump use

BACKGROUND

Black very low birth weight (VLBW; < 1500 g birth weight) and very preterm (VP, < 32 weeks gestational age, inclusive of extremely preterm, < 28 weeks gestational age) infants are significantly less likely than other VLBW and VP infants to receive mother's own milk (MOM) through to discharge from the neonatal intensive care unit (NICU). The costs associated with adhering to pumping maternal breast milk are borne by mothers and contribute to this disparity. This randomized controlled trial tests the effectiveness and cost-effectiveness of an intervention to offset maternal costs associated with pumping.

METHODS

This randomized control trial will enroll 284 mothers and their VP infants to test an intervention (NICU acquires MOM) developed to facilitate maternal adherence to breast pump use by offsetting maternal costs that serve as barriers to sustaining MOM feedings and the receipt of MOM at NICU discharge. Compared to current standard of care (mother provides MOM), the intervention bundle includes three components: a) free hospital-grade electric breast pump, b) pickup of MOM, and c) payment for opportunity costs. The primary outcome is infant receipt of MOM at the time of NICU discharge, and secondary outcomes include infant receipt of any MOM during the NICU hospitalization, duration of MOM feedings (days), and cumulative dose of MOM feedings (total mL/kg of MOM) received by the infant during the NICU hospitalization; maternal duration of MOM pumping (days) and volume of MOM pumped (mLs); and total cost of NICU care. Additionally, we will compare the cost of the NICU acquiring MOM versus NICU acquiring donor human milk if MOM is not available and the cost-effectiveness of the intervention (NICU acquires MOM) versus standard of care (mother provides MOM).

DISCUSSION

This trial will determine the effectiveness of an economic intervention that transfers the costs of feeding VLBWand VP infants from mothers to the NICU to address the disparity in the receipt of MOM feedings at NICU discharge by Black infants. The cost-effectiveness analysis will provide data that inform the adoption and scalability of this intervention.

Financial Incentives for Preventing Postpartum return to Smoking (FIPPS): study protocol for a three-arm randomised controlled trial

Background

Financial incentives are an effective way of helping women to stop smoking during pregnancy. Unfortunately, most women who stop smoking at this time return to smoking within 12 months of the infant’s birth. There is no evidence for interventions that are effective at preventing postpartum smoking relapse. Financial incentives provided after the birth may help women to sustain cessation. This randomised controlled trial will assess the effectiveness and cost-effectiveness of financial incentives to help women who are abstinent from smoking at end-of-pregnancy to avoid return to smoking up to 12 months postpartum.

Methods

This is a UK-based, multi-centre, three-arm, superiority, parallel group, individually randomised controlled trial, with 1:1:1 allocation. It will compare the effectiveness of two financial incentive interventions with each other (one intervention for up to 3 months postpartum offering up to £120 of incentives (£60 for the participant and £60 for a significant other support); the other for up to 12 months postpartum with up to £300 of incentives (£240 for the participant and £60 for a significant other support) and with a no incentives/usual care control group. Eligible women will be between 34 weeks gestation and 2 weeks postpartum, abstinent from smoking for at least 4 weeks, have an expired carbon monoxide (CO) reading < 4 parts per million (ppm), aged at least 16 years, intend remaining abstinent from smoking after the birth and able to speak and read English.

The primary outcome is self-reported, lapse-free, smoking abstinence from the last quit attempt in pregnancy until 12 months postpartum, biochemically validated by expired CO and/or salivary cotinine or anabasine. Outcomes will be analysed by intention-to-treat and regression models used to compare the proportion of abstinent women between the two intervention groups and between each intervention group and the control group. An economic evaluation will assess the cost-effectiveness of offering incentives and a qualitative process evaluation will examine barriers and facilitators to trial retention, effectiveness and implementation.

Discussion

This pragmatic randomised controlled trial will test whether offering financial incentives is effective and cost-effective for helping women to avoid smoking relapse during the 12 months after the birth of their baby.

The Impact of Reproductive Issues on Preferences of Women with Relapsing Multiple Sclerosis for Disease-Modifying Treatments

BACKGROUND

Relapsing-remitting multiple sclerosis (RRMS) is an incurable disease characterised by relapses (periods of function loss) followed by full or partial recovery, and potential permanent disability over time. Many disease-modifying treatments (DMTs) exist that help reduce relapses and slow disease progression. Most are contraindicated during conception/pregnancy and some require a discontinuation period before trying to conceive. Although around three-quarters of people with RRMS are women, there is limited knowledge about how reproductive issues impact DMT preference.

OBJECTIVE

The aim of this study was to measure the preferences for DMTs of women with RRMS who are considering pregnancy.

DESIGN

An online discrete choice experiment (DCE).

METHODS

Participants chose between two hypothetical DMTs characterised by a set of attributes, then indicated if they preferred their choice to no treatment. Attributes were identified from interviews and focus groups with people with RRMS and MS professionals, as well as literature reviews, and included the probability of problems with pregnancy, discontinuation of DMTs, and breastfeeding safety. In each DCE task, participants were asked to imagine making decisions in three scenarios: now; when trying to conceive; and when pregnant.

ANALYSIS

Two mixed logit models were estimated, one to assess the statistical significance between scenarios and one in maximum acceptable risk space to allow comparison of the magnitudes of parameters between scenarios.

SAMPLE

Women with RRMS who were considering having a child in the future, recruited from a UK MS patient register.

RESULTS

Sixty respondents completed the survey. Participants preferred no treatment in 12.6% of choices in the 'now' scenario, rising significantly to 37.6% in the 'trying to conceive' scenario and 60.3% in the 'pregnant' scenario (Kruskal-Wallis p < 0.001). This pattern corresponds with results from models that included a no-treatment alternative-specific constant (ASC) capturing differences between taking and not taking a DMT not specified by the attributes. The ASC was lower in the trying to conceive scenario than in the now scenario, and lower still in the pregnant scenario, indicating an intrinsic preference for no treatment. Participants also placed relatively less preference on reducing relapses and avoiding disease progression in the trying to conceive and pregnant scenarios compared with a lower risk of problems with pregnancy. In the trying to conceive scenario, participants' preference for treatments with shorter washout periods increased.

CONCLUSION

Women with RRMS considering having a child prefer DMTs with more favourable reproduction-related attributes, even when not trying to conceive. Reproductive issues also influenced preferences for DMT attributes not directly related to pregnancy, with preferences dependent on the life circumstances in which choices were made. The design of the DCE highlights the benefits of considering the scenario in which participants make choices, as they may change over time.

Cost-effectiveness evidence for strategies to promote or support breastfeeding: a systematic search and narrative literature review

BACKGROUND

Global health policy recommends exclusive breastfeeding until infants are 6 months. Little is known about the cost-effectiveness of breastfeeding promotion strategies. This paper presents a systematic search and narrative review of economic evaluations of strategies to support or promote breastfeeding. The aim of the review is to bring together current knowledge to guide researchers and commissioners towards potentially cost-effective strategies to promote or support breastfeeding.

METHODS

Searches were conducted of electronic databases, including MEDLINE and Scopus, for economic evaluations relevant to breastfeeding, published up to August 2019. Records were screened against pre-specified inclusion/exclusion criteria and quality was assessed using a published checklist. Costs reported in included studies underwent currency conversion and inflation to a single year and currency so that they could be compared. The review protocol was registered on the PROSPERO register of literature reviews (ID, CRD42019141721).

RESULTS

There were 212 non-duplicate citations. Four were included in the review, which generally indicated that interventions were cost-effective. Two studies reported that breastfeeding promotion for low-birth weight babies in critical care is associated with lower costs and greater health benefits than usual care and so is likely to be cost-effective. Peer-support for breastfeeding was associated with longer duration of exclusivity with costs ranging from £19-£107 per additional month (two studies).

CONCLUSIONS

There is limited published evidence on the cost-effectiveness of strategies to promote breastfeeding, although the quality of the current evidence is reasonably high. Future studies should integrate evaluations of the effectiveness of strategies with economic analyses.

Text messaging and financial incentives to encourage weight loss in men with obesity: the Game of Stones feasibility RCT

Background

In 2016, 26% of UK men were estimated to be obese. Systematic reviews suggest that few men engage in formal weight loss interventions that support weight reduction and improve health.

Objective

To co-produce, with patient and public involvement, an acceptable and feasible randomised controlled trial design to test a men-only weight management intervention.

Design

This was a two-phase feasibility study. Phase 1 was the development of intervention components, study procedures and materials including a discrete choice experiment with survey questions. Phase 2 was an individually randomised three-arm feasibility trial over 12 months. Qualitative interviews were conducted at 3 and 12 months.

Setting

The setting was two sites in Scotland that had disadvantaged urban and rural areas and differed in employment levels and ethnic groups.

Participants

In phase 1, 1045 men with obesity were recruited by Ipsos MORI (London, UK; www.ipsos.com/ipsos-mori/en-uk) to represent the UK population. In phase 2, 105 men with obesity were recruited in the community or through general practice obesity registers. Qualitative interviews were conducted with 50 men at 3 months and with 33 men at 12 months.

Interventions

The trial arms were narrative short message service (SMS) for 12 months (SMS only), financial endowment incentive informed by loss aversion and linked to achievement of weight loss targets plus narrative SMS for 12 months (SMS + I), and waiting list control group for 12 months followed by 3 months of an alternative SMS style developed based on feedback from men who had received the narrative SMS (control).

Main outcome measures

The main outcome measures were acceptability and feasibility of recruitment, retention, engagement, intervention components and trial procedures. Outcomes were assessed by examining procedural, quantitative and qualitative data at 3, 6 and 12 months.

Results

The most acceptable incentive strategy, based on the discrete choice experiment results, was to verify weight loss of 5% at 3 months, verify weight loss of 10% at 6 months and maintain weight loss of 10% at 12 months. Overall, 105 men with obesity from across the socioeconomic spectrum were successfully recruited to target, 59% of whom lived in more disadvantaged areas. Retention at 12 months was acceptable (74%) and was higher among individuals from disadvantaged areas. Narrative SMS were acceptable to many men, with a minority reporting negative reactions. Incentives were acceptable but were not the primary motivation for behaviour change. Twelve men in the incentive arm (33%) secured at least some money and three (8%) secured the full amount. Both intervention arms lost some weight, with greater weight loss in the arm that received SMS and incentives. The alternative SMS based on men’s feedback received no strong negative reactions.

Limitations

Fewer participants from the SMS + I arm (64%) completed the study at 12 months than did those in the SMS-only (79%) and control (83%) arms. The reasons for this difference were complex.

Conclusions

The men-only weight management intervention consisting of narrative SMS and financial incentives was acceptable and feasible, meeting the progression criteria for a full trial. Tailoring of SMS may improve acceptability and retention.

Future work

Minor refinements to the intervention components based on the study findings will be made prior to testing in a multisite definitive randomised controlled trial.

A qualitative exploration of using financial incentives to improve vaccination uptake via consent form return in female adolescents in London

OBJECTIVES

Incentivising vaccine consent form return may improve vaccine uptake and be seen as less coercive than incentivising vaccination itself. We assessed the acceptability of financial incentives in this context among adolescent females and explored potential mechanisms by which incentives might change behaviour.

DESIGN

Focus groups and analysis of free-text questionnaire responses.

METHODS

Study 1: 36 female secondary students in London (age 13-14) participated in six focus groups exploring the use of incentives in the context of vaccination. Data were analysed thematically. Study 2: was conducted to triangulate the findings of Study 1, by analysing free-text questionnaire responses from 181 female secondary students in London (age 12-13) reporting their opinion of incentivising consent form return. Data from Study 1 was also used to explore perceived potential mechanisms of action by which incentives might encourage consent form return.

RESULTS

Focus group participants had positive attitudes towards incentives, with 61% of free-text responses also expressing this. Most focus group participants thought that incentives would encourage consent form return (18% of free-text respondents spontaneously also mentioned this). While incentivising consent form return was seen as ethical, focus group participants who incorrectly thought that vaccine receipt was being incentivised raised concerns about bribery, although only 4% of free text respondents reported these concerns. Frequently raised mechanisms of action included incentives increasing engagement with, and the perceived value of consent form return.

CONCLUSIONS

Adolescents had positive views of financially incentivising consent form return to promote vaccine uptake, although care must be taken to reduce misconceptions regarding what is being incentivised. Incentivising vaccination was seen as coercive, but incentivising actions that increase the likelihood of vaccination (i.e. consent form return) were not. Incentives may encourage adolescents to return consent forms by helping them engage with this behaviour or increasing its' perceived value.

Utilising Patient and Public Involvement in Stated Preference Research in Health: Learning from the Existing Literature and a Case Study

Publications reporting discrete choice experiments of healthcare interventions rarely discuss whether patient and public involvement (PPI) activities have been conducted. This paper presents examples from the existing literature and a detailed case study from the National Institute for Health Research-funded PATHWAY programme that comprehensively included PPI activities at multiple stages of preference research. Reflecting on these examples, as well as the wider PPI literature, we describe the different stages at which it is possible to effectively incorporate PPI across preference research, including the design, recruitment and dissemination of projects. Benefits of PPI activities include gaining practical insights from a wider perspective, which can positively impact experiment design as well as survey materials. Further benefits included advice around recruitment and reaching a greater audience with dissemination activities, amongst others. There are challenges associated with PPI activities; examples include time, cost and outlining expectations. Overall, although we acknowledge practical difficulties associated with PPI, this work highlights that it is possible for preference researchers to implement PPI across preference research. Further research systematically comparing methods related to PPI in preference research and their associated impact on the methods and results of studies would strengthen the literature.

A mobile health-facilitated behavioural intervention for community health workers improves exclusive breastfeeding and early infant HIV diagnosis in India: a cluster randomized trial

INTRODUCTION

India's national AIDS Control Organization implemented World Health Organization's option B+ HIV prevention of mother-to-child transmission (PMTCT) guidelines in 2013. However, scalable strategies to improve uptake of new PMTCT guidelines to reduce new infection rates are needed. This study assessed impact of Mobile Health-Facilitated Behavioral Intervention on the uptake of PMTCT services.

METHODS

A cluster-randomized trial of a mobile health (mHealth)-supported behavioural training intervention targeting outreach workers (ORWs) was conducted in four districts of Maharashtra, India. Clusters (one Integrated Counselling and Testing Center (ICTC, n = 119), all affiliated ORWs (n = 116) and their assigned HIV-positive pregnant/postpartum clients (n = 1191)) were randomized to standard-of-care (SOC) ORW training vs. the COMmunity home Based INDia (COMBIND) intervention - specialized behavioural training plus a tablet-based mHealth application to support ORW-patient communication and patient engagement in HIV care. Impact on uptake of maternal antiretroviral therapy at delivery, exclusive breastfeeding at six months, infant nevirapine prophylaxis, and early infant diagnosis at six months was assessed using multi-level random-effects logistic regression models.

RESULTS

Of 1191 HIV-positive pregnant/postpartum women, 884 were eligible for primary outcome assessment; 487 were randomized to COMBIND. Multivariable analyses identified no statistically significant differences in any primary outcome by study arm. COMBIND was associated with higher uptake of exclusive breastfeeding at two months (adjusted Odds Ratio (aOR), 2.10; 95% CI 1.06 to 4.15) and early infant diagnosis at six weeks (aOR, 2.19; 95% CI 1.05 to 3.98) than SOC.

CONCLUSIONS

The COMBIND intervention was easily integrated into India's existing PMTCT programme and improved early uptake of two PMTCT components that require self-motivated health-seeking behaviour, thus providing preliminary evidence to support COMBIND as a potentially scalable PMTCT strategy. Further study would identify modifications needed to optimize other PMTCT outcomes.

An assets-based intervention before and after birth to improve breastfeeding initiation and continuation: the ABA feasibility RCT

Background

The UK has low levels of breastfeeding initiation and continuation, with evident socioeconomic disparities. To be inclusive, peer-support interventions should be woman-centred rather than breastfeeding-centred. Assets-based approaches to public health focus on the positive capabilities of individuals and communities, rather than their deficits and problems. The Assets-based feeding help Before and After birth (ABA) intervention offers an assets-based approach based on behaviour change theory.

Objective

To investigate the feasibility of delivering the ABA infant feeding intervention in a randomised controlled trial.

Design

This was an individually randomised controlled feasibility trial; women were randomised in a 1 : 1 ratio to either the intervention group or the comparator (usual care) group.

Setting

Two separate English sites were selected because they had an existing breastfeeding peer support service, relatively high levels of socioeconomic disadvantage and low rates of breastfeeding.

Participants

Women aged ≥ 16 years who were pregnant with their first child, irrespective of feeding intention (n = 103), were recruited by researchers in antenatal clinics.

Interventions

Proactive, woman-centred support, using an assets-based approach and including behaviour change techniques, was provided by an infant-feeding helper (a breastfeeding peer supporter trained in the ABA intervention) and delivered through face-to-face contact, telephone conversations and text messages. The intervention commenced at around 30 weeks’ gestation and could continue until 5 months postnatally.

Main outcome measures

The main outcome measures were feasibility of intervention delivery with the requisite intensity and duration; acceptability to women, infant-feeding helpers and maternity services; and feasibility of a future randomised controlled trial. Outcomes included recruitment rates and follow-up rates at 3 days, 8 weeks and 6 months postnatally, and outcomes for a future full trial were collected via participant questionnaires. A mixed-methods process evaluation included qualitative interviews with women, infant-feeding helpers and maternity services; infant-feeding helper logs; and audio-recordings of antenatal contacts to check intervention fidelity.

Results

Of the 135 eligible women approached, 103 (76.3%) agreed to participate. The study was successful in recruiting teenagers (8.7%) and women living in areas of socioeconomic disadvantage (37.3% resided in the most deprived 40% of small areas in England). Postnatal follow-up rates were 68.0%, 85.4% and 80.6% at 3 days, 8 weeks and 6 months, respectively. Feeding status at 8 weeks was obtained for 95.1% of participants. Recruitment took place from February 2017 until August 2017. It was possible to recruit and train existing peer supporters to the infant-feeding helper role. The intervention was delivered to most women with relatively high fidelity. Among the 50 women in the intervention group, 39 received antenatal visits and 40 received postnatal support. Qualitative data showed that the intervention was acceptable. There was no evidence of intervention-related harms.

Limitations

Birth notification delays resulted in delays in the collection of postnatal feeding status data and in the offer of postnatal support. In addition, the intervention needs to better consider all infant-feeding types and did not adequately accommodate women who delivered prematurely.

Conclusion

It is feasible to deliver the intervention and trial.

Future work

The intervention should be tested in a fully powered randomised controlled trial.

Exposure to Tobacco, Environmental Tobacco Smoke and Nicotine in Pregnancy: A Pragmatic Overview of Reviews of Maternal and Child Outcomes, Effectiveness of Interventions and Barriers and Facilitators to Quitting

The aim of this review of reviews was to collate the latest evidence from systematic reviews about the maternal and child health outcomes of being exposed to tobacco and nicotine during pregnancy; the effectiveness of interventions designed to reduce these exposures, and barriers to and facilitators of smoking cessation during pregnancy. Two databases were searched to obtain systematic reviews published from 2010 to 2019. Pertinent data from 76 articles were summarized using a narrative synthesis (PROSPERO reference: CRD42018085896). Exposure to smoke or tobacco in other forms during pregnancy is associated with an increased risk of obstetric complications and adverse health outcomes for children exposed in-utero. Counselling interventions are modestly effective, while incentive-based interventions appear to substantially increase smoking cessation. Nicotine replacement therapy is effective during pregnancy but the evidence is not conclusive. Predictors and barriers to smoking cessation in pregnancy are also discussed. Smoking during pregnancy poses substantial risk to mother's and child's health. Psychosocial interventions and nicotine replacement therapy (NRT) appear to be effective in helping pregnant women quit smoking. Barriers to smoking cessation must be identified and steps taken to eradicate them in order to reduce smoking among pregnant women. More research is needed on smoking cessation medications and e-cigarettes.

The smoking cessation in pregnancy incentives trial (CPIT): study protocol for a phase III randomised controlled trial

BACKGROUND

Eighty per cent of UK women have at least one baby, making pregnancy an opportunity to help women stop smoking before their health is irreparably compromised. Smoking cessation during pregnancy helps protect infants from miscarriage, still birth, low birth weight, asthma, attention deficit disorder and adult cardiovascular disease. UK national guidelines highlight lack of evidence for effectiveness of financial incentives to help pregnant smokers quit. This includes a research recommendation: within a UK context, are incentives an acceptable, effective and cost-effective way to help pregnant women who smoke to quit?

METHODS

The Cessation in Pregnancy Incentives Trial (CPIT) III is a pragmatic, 42-month, multi-centre, parallel-group, individually randomised controlled superiority trial of the effect on smoking status of adding to usual Stop Smoking Services (SSS) support, the offer of up to £400 of financial voucher incentives, compared with usual support alone, to quit smoking during pregnancy. Participants (n = 940) are pregnant smokers (age > 16 years, < 24 weeks pregnant, English speaking), who consent via telephone to take part and are willing to be followed-up in late pregnancy and 6 months after birth. The primary outcome is cotinine/anabasine-validated abstinence from smoking in late pregnancy. Secondary outcomes include engagement with SSS, quit rates at 4 weeks from agreed quit date and 6 months after birth, and birth weight. Outcomes will be analysed by intention to treat, and regression models will be used to compare treatment effects on outcomes. A meta-analysis will include data from the feasibility study in Glasgow. An economic evaluation will assess cost-effectiveness from a UK NHS perspective. Process evaluation using a case-study approach will identify opportunities to improve recruitment and learning for future implementation. Research questions include: what is the therapeutic efficacy of incentives; are incentives cost-effective; and what are the potential facilitators and barriers to implementing incentives in different parts of the UK?

DISCUSSION

This phase III trial in Scotland, England and Northern Ireland follows a successful phase II trial in Glasgow, UK. The participating sites have diverse SSS that represent most cessation services in the UK and serve demographically varied populations. If found to be acceptable and cost-effective, this trial could demonstrate that financial incentives are effective and transferable to most UK SSS for pregnant women.

What Is Next for Patient Preferences in Health Technology Assessment? A Systematic Review of the Challenges

BACKGROUND

Integrating patient preferences in Health Technology Assessment (HTA) is argued to improve uptake, adherence, and patient satisfaction. However, how to elicit and incorporate these preferences in HTA in a systematic and scientifically valid manner is subject to debate.

OBJECTIVE

This article provides a systematic review of the challenges to integrating patient preferences in HTA that have been raised in the literature about patient preferences in HTA.

METHODS

A systematic review of articles published between 2013 and 2017 addressing challenges to the integration of patient preferences in HTA was conducted in 7 databases. All issues with respect to the integration of patient preferences in HTA were extracted and divided into 5 categories: conceptual, normative, procedural, methodological, and practical issues. The issues were ranked according to how often they were mentioned.

RESULTS

Of 2147 retrieved articles, 67 were included in the analysis. Thirty-seven unique research issues were identified. In the majority of the articles, methodological issues were posed (82%), followed by procedural (73%), normative (51%), practical (24%), and conceptual (9%) issues. Frequently posed methodological issues concerned preference heterogeneity and choice of method. Common procedural issues concerned how to evaluate the impact of preference studies and their degree of being evidence based.

CONCLUSIONS

This article provides an overview of issues with respect to the integration of patient preferences in HTA procedures. Most issues were of a methodological or procedural nature; yet, the large number of different issues points to the overall importance of further researching the different aspects concerned with patient preferences in HTA. Through its ranking of how many articles mention particular issues, this article proposes an implicit research agenda.

Addressing Tobacco Use in Underserved Communities Through a Peer-Facilitated Smoking Cessation Program

Communities Engaged and Advocating for a Smoke-Free Environment (CEASE) is a long-standing research partnership between a university and the neighboring community that was established to reduce tobacco use among poor and underserved residents. The CEASE tobacco cessation program was implemented in four phases, with each new phase applying lessons learned from the previous phases to improve outcomes. This study describes CEASE's community-based approach and reports results from implementing the second phase of the intervention which, among other things, varied in the type of incentives, setting, and providers used. CEASE implemented a mixed-methods study following the Community-Based Participatory Research (CBPR) approach. During Phase II, a total of 398 smokers were recruited into two 12-session group counseling interventions facilitated by trained peers in community venues, which differed in the type of incentives used to increase participation and reward the achievement of milestones. At 12-week follow-up, 21% of all participants reported not smoking, with a retention rate (i.e., attendance at six or more of the 12 cessation classes offered) of 51.9%. No significant differences in cessation outcomes were found between the two study arms. Using a CBPR approach resulted in a peer-led model of care with improved outcomes compared to Phase I, which was provided by clinicians. The combined use of monetary and non-monetary incentives was helpful in increasing participation in the program but did not significantly impact smoking cessation. A CBPR approach can increase the acceptability and effectiveness of cessation services for underserved populations.

Women's views about a free breast pump service: Online survey informing intervention development

Improving breastfeeding outcomes is a global priority; however, in the United Kingdom, continuation of breastfeeding remains low. Growing empirical evidence suggests a free breast pump service might be an acceptable and feasible incentive intervention to improve breastfeeding outcomes and reduce heath inequalities. To inform intervention development, we conducted an online survey with women recruited via social media using snowball sampling. Data were analysed descriptively (closed questions) with qualitative thematic analysis (free text). The survey was completed by 666 women, most of whom had recently breastfed and used a breast pump. Participants agreed that free pump hire (rental/loan; 567 women; 85.1%) or a free pump to keep (408; 61.3%) should be provided. Free text comments provided by 408 women (free pump) and 309 women (free hire) highlighted potential benefits: helping women to continue breastfeeding; express milk; overcome difficulties; and pump choice. Concerns are possible effect on breast milk supply, reduced breastfeeding, pumps replacing good support for breastfeeding, and pump hire hygiene. Personal and societal costs are important issues. Some suggested a pump service should be for low-income mothers, those with feeding difficulties or sick/preterm infants. A one-size service would not suit all and vouchers were proposed. Some suggested fees and deposits to prevent waste. To our knowledge, this is the first study reporting views about the acceptability of providing a free breast pump hire service. Mothers support and wish to have a say in breast pump service development. Future evaluations should address impact on feeding outcomes, professional support, hygiene for hired pumps, and costs.

Reducing toxic stress in the neonatal intensive care unit to improve infant outcomes

In 2011, the American Academy of Pediatrics (AAP) published a technical report on the lifelong effects of early toxic stress on human development, and included a new framework for promoting pediatric health: the Ecobiodevelopmental Framework for Early Childhood Policies and Programs. We believe that hospitalization is a specific form of toxic stress for the neonatal patient, and that toxic stress must be addressed by the nursing profession in order to substantially improve outcomes for the critically ill neonate. Approximately 4% of normal birthweight newborns and 85% of low birthweight newborns are hospitalized each year in the highly technological neonatal intensive care unit (NICU). Neonates are exposed to roughly 70 stressful procedures a day during hospitalization, which can permanently and negatively alter the infant's developing brain. Neurologic deficits can be partly attributed to the frequent, toxic, and cumulative exposure to stressors during NICU hospitalization. However, the AAP report does not provide specific action steps necessary to address toxic stress in the NICU and realize the new vision for pediatric health care outlined therein. Therefore, this paper applies the concepts and vision laid out in the AAP report to the care of the hospitalized neonate and provides action steps for true transformative change in neonatal intensive care. We review how the environment of the NICU is a significant source of toxic stress for hospitalized infants. We provide recommendations for caregiving practices that could significantly buffer the toxic stress experienced by hospitalized infants. We also identify areas of research inquiry that are needed to address gaps in nursing knowledge and to propel nursing science forward. Finally, we advocate for several public policies that are not fully addressed in the AAP technical report, but are vital to the health and development of all newborns.

Discrete Choice Experiments in Health Economics: Past, Present and Future

OBJECTIVES

Discrete choice experiments (DCEs) are increasingly advocated as a way to quantify preferences for health. However, increasing support does not necessarily result in increasing quality. Although specific reviews have been conducted in certain contexts, there exists no recent description of the general state of the science of health-related DCEs. The aim of this paper was to update prior reviews (1990-2012), to identify all health-related DCEs and to provide a description of trends, current practice and future challenges.

METHODS

A systematic literature review was conducted to identify health-related empirical DCEs published between 2013 and 2017. The search strategy and data extraction replicated prior reviews to allow the reporting of trends, although additional extraction fields were incorporated.

RESULTS

Of the 7877 abstracts generated, 301 studies met the inclusion criteria and underwent data extraction. In general, the total number of DCEs per year continued to increase, with broader areas of application and increased geographic scope. Studies reported using more sophisticated designs (e.g. D-efficient) with associated software (e.g. Ngene). The trend towards using more sophisticated econometric models also continued. However, many studies presented sophisticated methods with insufficient detail. Qualitative research methods continued to be a popular approach for identifying attributes and levels.

CONCLUSIONS

The use of empirical DCEs in health economics continues to grow. However, inadequate reporting of methodological details inhibits quality assessment. This may reduce decision-makers' confidence in results and their ability to act on the findings. How and when to integrate health-related DCE outcomes into decision-making remains an important area for future research.

Stakeholder involvement in systematic reviews: a scoping review

BACKGROUND

There is increasing recognition that it is good practice to involve stakeholders (meaning patients, the public, health professionals and others) in systematic reviews, but limited evidence about how best to do this. We aimed to document the evidence-base relating to stakeholder involvement in systematic reviews and to use this evidence to describe how stakeholders have been involved in systematic reviews.

METHODS

We carried out a scoping review, following a published protocol. We searched multiple electronic databases (2010-2016), using a stepwise searching approach, supplemented with hand searching. Two authors independently screened and discussed the first 500 abstracts and, after clarifying selection criteria, screened a further 500. Agreement on screening decisions was 97%, so screening was done by one reviewer only. Pre-planned data extraction was completed, and the comprehensiveness of the description of methods of involvement judged. Additional data extraction was completed for papers judged to have most comprehensive descriptions. Three stakeholder representatives were co-authors for this systematic review.

RESULTS

We included 291 papers in which stakeholders were involved in a systematic review. Thirty percent involved patients and/or carers. Thirty-two percent were from the USA, 26% from the UK and 10% from Canada. Ten percent (32 reviews) were judged to provide a comprehensive description of methods of involving stakeholders. Sixty-nine percent (22/32) personally invited people to be involved; 22% (7/32) advertised opportunities to the general population. Eighty-one percent (26/32) had between 1 and 20 face-to-face meetings, with 83% of these holding ≤ 4 meetings. Meetings lasted 1 h to ½ day. Nineteen percent (6/32) used a Delphi method, most often involving three electronic rounds. Details of ethical approval were reported by 10/32. Expenses were reported to be paid to people involved in 8/32 systematic reviews.

DISCUSSION/CONCLUSION

We identified a relatively large number (291) of papers reporting stakeholder involvement in systematic reviews, but the quality of reporting was generally very poor. Information from a subset of papers judged to provide the best descriptions of stakeholder involvement in systematic reviews provide examples of different ways in which stakeholders have been involved in systematic reviews. These examples arguably currently provide the best available information to inform and guide decisions around the planning of stakeholder involvement within future systematic reviews. This evidence has been used to develop online learning resources.

Evaluation of a project to engage patients in the development of a patient-reported measure for HIV care (the I-Score Study)

Background

Patient engagement (PE), patients’ meaningful involvement in research through partnerships and sensitivity to their expertise, is receiving attention. However, PE initiatives are poorly reported and little is known about patients’ perspective on PE.

Objective

To document and evaluate the first phase (22 months) of a PE Project for the I‐Score Study which is developing a patient‐reported measure of HIV treatment adherence barriers, we describe the nature of PE conducted, determine the level of PE achieved and present its impacts from the engaged patients’ perspective.

Setting and participants

A Montreal‐based committee of ten people with HIV was recruited from community and clinical settings and participated in: I‐Score study decision making, knowledge dissemination, research on the experience of people with HIV and the PE project's evaluation.

Methods

The evaluation followed a convergent parallel mixed‐methods design. Data collection included participant observation, a satisfaction survey and meeting minutes/transcriptions. Analysis entailed reporting PE activities, generating descriptive statistics and thematically analysing qualitative material.

Results

PE consisted of twelve meetings, including two focus groups (needs assessment), in addition to four knowledge dissemination activities. PE levels showed an increase: the first four regular meetings entailed information/consultation, while subsequent meetings reached implication/collaboration. Regarding impacts, patients indicated high and stable satisfaction rates (M = 4.4/5; SD = 0.76). Furthermore, thematic analysis identified “positive interactions,” “co‐learning,” “self‐determination,” and “the collective management of confidentiality” as important PE impacts for engaged patients.

Conclusion

This PE Project evaluation highlighted growing engagement levels, high satisfaction rates and the importance of a patient‐centric approach to PE.

A framework to address key issues of neonatal service configuration in England: the NeoNet multimethods study

Background

There is an inherent tension in neonatal services between the efficiency and specialised care that comes with centralisation and the provision of local services with associated ease of access and community benefits. This study builds on previous work in South West England to address these issues at a national scale.

Objectives

(1) To develop an analytical framework to address key issues of neonatal service configuration in England, (2) to investigate visualisation tools to facilitate the communication of findings to stakeholder groups and (3) to assess parental preferences in relation to service configuration alternatives.

Main outcome measures

The ability to meet nurse staffing guidelines, volumes of units, costs, mortality, number and distance of transfers, travel distances and travel times for parents.

Design

Descriptive statistics, location analysis, mathematical modelling, discrete event simulation and economic analysis were used. Qualitative methods were used to interview policy-makers and parents. A parent advisory group supported the study.

Setting

NHS neonatal services across England.

Data

Neonatal care data were sourced from the National Neonatal Research Database. Information on neonatal units was drawn from the National Neonatal Audit Programme. Geographic and demographic data were sourced from the Office for National Statistics. Travel time data were retrieved via a geographic information system. Birth data were sourced from Hospital Episode Statistics. Parental cost data were collected via a survey.

Results

Location analysis shows that to achieve 100% of births in units with ≥ 6000 births per year, the number of birth centres would need to be reduced from 161 to approximately 72, with more parents travelling > 30 minutes. The maximum number of neonatal intensive care units (NICUs) needed to achieve 100% of very low-birthweight infants attending high-volume units is 36 with existing NICUs, or 48 if NICUs are located wherever there is currently a neonatal unit of any level. Simulation modelling further demonstrated the workforce implications of different configurations. Mortality modelling shows that the birth of very preterm infants in high-volume hospitals reduces mortality (a conservative estimate of a 1.2-percentage-point lower risk) relative to these births in other hospitals. It is currently not possible to estimate the impact of mortality for infants transferred into NICUs. Cost modelling shows that the mean length of stay following a birth in a high-volume hospital is 9 days longer and the mean cost is £5715 more than for a birth in another neonatal unit. In addition, the incremental cost per neonatal life saved is £460,887, which is comparable to other similar life-saving interventions. The analysis of parent costs identified unpaid leave entitlement, food, travel, accommodation, baby care and parking as key factors. The qualitative study suggested that central concerns were the health of the baby and mother, communication by medical teams and support for families.

Limitations

The following factors could not be modelled because of a paucity of data – morbidity outcomes, the impact of transfers and the maternity/neonatal service interface.

Conclusions

An evidence-based framework was developed to inform the configuration of neonatal services and model system performance from the perspectives of both service providers and parents.

Future work

To extend the modelling to encompass the interface between maternity and neonatal services.

A qualitative investigation of the health economic impacts of bariatric surgery for obesity and implications for improved practice in health economics

Obesity is an economic problem. Bariatric surgery is cost-effective for severe and resistant obesity. Most economic evaluations of bariatric surgery use administrative data and narrowly defined direct medical costs in their quantitative analyses. Demand far outstrips supply for bariatric surgery. Further allocation of health care resources to bariatric surgery (particularly public) could be stimulated by new health economic evidence that supports the provision of bariatric surgery. We postulated that qualitative research methods would elicit important health economic dimensions of bariatric surgery that would typically be omitted from the current economic evaluation framework, nor be reported and therefore not considered by policymakers with sufficient priority. We listened to patients: Focus group data were analysed thematically with software assistance. Key themes were identified inductively through a dialogue between the qualitative data and pre-existing economic theory (perspective, externalities, and emotional capital). We identified the concept of emotional capital where participants described life-changing desires to be productive and participate in their communities postoperatively. After self-funding bariatric surgery, some participants experienced financial distress. We recommend a mixed-methods approach to the economic evaluation of bariatric surgery. This could be operationalised in health economic model conceptualisation and construction, through to the separate reporting of qualitative results to supplement quantitative results.

How to incorporate patient and public perspectives into the design and conduct of research

International government guidance recommends patient and public involvement (PPI) to improve the relevance and quality of research.  PPI is defined as research being carried out 'with' or 'by' patients and members of the public rather than 'to', 'about' or 'for' them ( http://www.invo.org.uk/). Patient involvement is different from collecting data from patients as participants.  Ethical considerations also differ.  PPI is about patients actively contributing through discussion to decisions about research design, acceptability, relevance, conduct and governance from study conception to dissemination.  Occasionally patients lead or do research.  The research methods of PPI range from informal discussions to partnership research approaches such as action research, co-production and co-learning. This article discusses how researchers can involve patients when they are applying for research funding and considers some opportunities and pitfalls.  It reviews research funder requirements, draws on the literature and our collective experiences as clinicians, patients, academics and members of UK funding panels.

Women's preferences for alternative financial incentive schemes for breastfeeding: A discrete choice experiment

Background

Increasing breastfeeding rates have been associated with reductions in disease in babies and mothers as well as in related costs. ‘Nourishing Start for Health (NoSH)’, a financial incentive scheme has been proposed as a potentially effective way to increase both the number of mothers breastfeeding and duration of breastfeeding.

Aims

To establish women’s relative preferences for different aspects of a financial incentive scheme for breastfeeding and to identify importance of scheme characteristics on probability on participation in an incentive scheme.

Methods

A discrete choice experiment (DCE) obtained information on alternative specifications of the NoSH scheme designed to promote continued breastfeeding duration until at least 6 weeks after birth. Four attributes framed alternative scheme designs: value of the incentive; minimum breastfeeding duration required to receive incentive; method of verifying breastfeeding; type of incentive. Three versions of the DCE questionnaire, each containing 8 different choice sets, provided 24 choice sets for analysis. The questionnaire was mailed to 2,531 women in the South Yorkshire Cohort (SYC) aged 16–45 years in IMD quintiles 3–5. The analytic approach considered conditional and mixed effects logistic models to account for preference heterogeneity that may be associated with a variation in effects mediated by respondents’ characteristics.

Results

564 women completed the questionnaire and a response rate of 22% was achieved. Most of the included attributes were found to affect utility and therefore the probability to participate in the incentive scheme. Higher rewards were preferred, although the type of incentive significantly affected women’s preferences on average. We found evidence for preference heterogeneity based on individual characteristics that mediated preferences for an incentive scheme.Conclusions

Although participants’ opinion in our sample was mixed, financial incentives for breastfeeding may be an acceptable and effective instrument to change behaviour. However, individual characteristics could mediate the effect and should therefore be considered when developing and targeting future interventions.

Predictors of smoking cessation during pregnancy: a systematic review and meta-analysis

AIM

To identify factors found in the research literature to be associated with smoking cessation in pregnancy.

METHODS

Electronic searches of the bibliographic databases of PubMed, EMBASE, PsycINFO, Elsevier, Scopus and ISI Web of Science were conducted to April 2017. All studies reporting factors associated with smoking cessation or continuing smoking during pregnancy were included and reviewed systematically, irrespective of study design. The Newcastle-Ottawa Quality Assessment Scale was used to assess the study quality. The DerSimonian & Laird random-effects model was used to conduct meta-analyses, and where effect estimates were reported for factors included in at least three studies.

RESULTS

Fifty-four studies, including 505 584 women globally who smoked before pregnancy, 15 clinical trials and 40 observational studies, were included in the review and 36 (65.5%) were considered to be of high quality. This review identified 11 socio-demographic, seven socially related, 19 smoking behaviour-related, five pregnancy-related, six health-related and six psychological factors that were associated significantly with smoking cessation during pregnancy. The most frequently observed significant factors associated with cessation were: higher level of education, pooled odds ratio (OR), 95% confidence interval (CI) = 2.16 (1.80-2.84), higher socio-economic status: 1.97 (1.20-3.24), overseas maternal birth: 2.00 (1.40-2.84), Medicaid coverage or private insurance: 1.54 (1.29-1.85), living with partner or married: 1.49 (1.38-1.61), partner/other members of the household do not smoke: 0.42 (0.35-0.50), lower heaviness of smoking index score: 0.45 (0.27-0.77, lower baseline cotinine level: 0.78 (0.64-0.94), low exposure to second-hand smoking: 0.45 (0.20-1.02), not consuming alcohol before and/or during pregnancy: 2.03 (1.47-2.80), primiparity: 1.85 (1.68-2.05), planned breastfeeding:1.99 (1.94-2.05), perceived adequate pre-natal care: 1.74 (1.38-2.19), no depression: 2.65 (1.62-4.30) and low stress during pregnancy: 0.58 (0.44-0.77).

CONCLUSION

A wide range of socio-demographics, relationship, social, smoking-related, pregnancy-related, health and psychological factors have been found to predict smoking cessation in pregnancy.

Assessing the acceptability of incentivising HPV vaccination consent form return as a means of increasing uptake

BACKGROUND

Uptake of human papillomavirus (HPV) vaccination is high overall but there are disparities in uptake, particularly by ethnicity. Incentivising vaccination consent form return is a promising approach to increase vaccination uptake. As part of a randomised feasibility trial we qualitatively assessed the acceptability of increasing uptake of HPV vaccination by incentivising consent form return.

METHODS

In the context of a two-arm, cluster randomised feasibility trial, qualitative free-text questionnaire responses were collected from adolescent girls (n = 181) and their parents (n = 61), assessing the acceptability of an incentive intervention to increase HPV vaccination consent form return. In the incentive intervention arm, girls who returned a signed consent form (regardless of whether consent was given or refused), had a 1-in-10 chance of winning a £50 shopping voucher. Telephone interviews were also conducted with members of staff from participating schools (n = 6), assessing the acceptability of the incentive. Data were analysed thematically.

RESULTS

Girls and parents provided a mix of positive, negative and ambivalent responses about the use of the incentive to encourage HPV vaccination consent form return. Both girls and parents held misconceptions about the nature of the incentive, wrongly believing that the incentive was dependent on vaccination receipt rather than consent form return. School staff members also expressed a mix of opinions on the acceptability of the incentive, including perceptions of effectiveness and ethics.

CONCLUSIONS

The use of an incentive intervention to encourage the return of HPV vaccination consent forms was found to be moderately acceptable to those receiving and delivering the intervention, although a number of changes are required to improve this. In particular, improving communication about the nature of the incentive to reduce misconceptions is vital. These findings suggest that incentivising consent form return may be an acceptable means of improving HPV vaccination rates, should improvements be made.

Application of Discrete-Choice Experiment Methods in Tobacco Control: A Systematic Review

BACKGROUND

Economic evidence relating to tobacco control is generally derived from the cost effectiveness of smoking-cessation programs or the economic impact of tobacco-induced disease, based on revealed-preference data. However, empirical estimates from stated-preference data on tobacco users' preferences, smoking behaviour and smoking cessation aids using analytical techniques such as discrete-choice experiments (DCEs) could be important for policy decision making in tobacco control.

OBJECTIVES

Our objective was to review the practice and utility of DCE methodology across nicotine- and tobacco-related issues, particularly smoking and smoking-cessation behaviour, anti-smoking policies and preferences for smoking-cessation aids.

METHODS

We searched the PubMed, MEDLINE and ECONLIT databases for full-text original research articles on tobacco-related issues published between January 2000 and April 2016 that used a DCE method. We summarised the evidence and methodological characteristics of DCEs according to Lancsar and Louviere, 2008.

RESULTS

Our review of the 12 eligible studies showed that DCE methodology was used to elicit smoker preferences and to evaluate tobacco-control policies. The majority of the studies were published in the last 5 years. The areas of application were smoking cessation, smoking behaviour, electronic cigarette use, water-pipe smoking and tobacco packaging. Monetary attributes were the most influential attributes in all studies. The design of the DCEs varied.

CONCLUSION

DCE studies of tobacco-related issues were methodologically consistent with guidelines proposed for conducting health-related DCEs.

Protocol for a feasibility trial for improving breast feeding initiation and continuation: assets-based infant feeding help before and after birth (ABA)

INTRODUCTION

Breast feeding improves the health of mothers and infants; the UK has low rates, with marked socioeconomic inequalities. While trials of peer support services have been effective in some settings, UK trials have not improved breast feeding rates. Qualitative research suggests that many women are alienated by the focus on breast feeding. We propose a change from breast feeding-focused interactions to respecting a woman's feeding choices, inclusion of behaviour change theory and an increased intensity of contacts in the 2 weeks after birth when many women cease to breast feed. This will take place alongside an assets-based approach that focuses on the positive capability of individuals, their social networks and communities.We propose a feasibility study for a multicentre randomised controlled trial of the Assets feeding help Before and After birth (ABA) infant feeding service versus usual care.

METHODS AND ANALYSIS

A two-arm, non-blinded randomised feasibility study will be conducted in two UK localities. Women expecting their first baby will be eligible, regardless of feeding intention. The ABA infant feeding intervention will apply a proactive, assets-based, woman-centred, non-judgemental approach, delivered antenatally and postnatally tailored through face-to-face contacts, telephone and SMS texts. Outcomes will test the feasibility of delivering the intervention with recommended intensity and duration to disadvantaged women; acceptability to women, feeding helpers and professionals; and feasibility of a future randomised controlled trial (RCT), detailing recruitment rates, willingness to be randomised, follow-up rates at 3 days, 8 weeks and 6 months, and level of outcome completion. Outcomes of the proposed full trial will also be collected. Mixed methods will include qualitative interviews with women/partners, feeding helpers and health service staff; feeding helper logs; and review of audio-recorded helper-women interactions to assess intervention fidelity.

ETHICS AND DISSEMINATION

Study results will inform the design of a larger multicentre RCT. The National Research Ethics Service Committee approved the study protocol.

A cluster randomised feasibility study of an adolescent incentive intervention to increase uptake of HPV vaccination

BACKGROUND

Uptake of human papillomavirus (HPV) vaccination is suboptimal among some groups. We aimed to determine the feasibility of undertaking a cluster randomised controlled trial (RCT) of incentives to improve HPV vaccination uptake by increasing consent form return.

METHODS

An equal-allocation, two-arm cluster RCT design was used. We invited 60 London schools to participate. Those agreeing were randomised to either a standard invitation or incentive intervention arm, in which Year 8 girls had the chance to win a £50 shopping voucher if they returned a vaccination consent form, regardless of whether consent was provided. We collected data on school and parent participation rates and questionnaire response rates. Analyses were descriptive.

RESULTS

Six schools completed the trial and only 3% of parents opted out. The response rate was 70% for the girls' questionnaire and 17% for the parents'. In the intervention arm, 87% of girls returned a consent form compared with 67% in the standard invitation arm. The proportion of girls whose parents gave consent for vaccination was higher in the intervention arm (76%) than the standard invitation arm (61%).

CONCLUSIONS

An RCT of an incentive intervention is feasible. The intervention may improve vaccination uptake but a fully powered RCT is needed.

Financial incentives to discontinue long-term benzodiazepine use: a discrete choice experiment investigating patient preferences and willingness to participate

OBJECTIVES

Investigate the acceptability of financial incentives for initiating a medically supervised benzodiazepine discontinuation programme among people with long-term benzodiazepine use and to identify programme features that influence willingness to participate.

METHODS

We conducted a discrete choice experiment in which we presented a variety of incentive-based programs to a sample of older adults with long-term benzodiazepine use identified using the outpatient electronic health record of a university-owned health system. We studied four programme variables: incentive amount for initiating the programme, incentive amount for successful benzodiazepine discontinuation, lottery versus certain payment and whether partial payment was given for dose reduction. Respondents reported their willingness to participate in the programmes and additional information was collected on demographics, history of use and anxiety symptoms.

RESULTS

The overall response rate was 28.4%. Among the 126 respondents, all four programme variables influenced stated preferences. Respondents strongly preferred guaranteed cash-based incentives as opposed to a lottery, and the dollar amount of both the starting and conditional incentives had a substantial impact on choice. Willingness to participate increased with the amount of conditional incentive. Programme participation also varied by gender, duration of use and income.

CONCLUSIONS

Participation in an incentive-based benzodiazepine discontinuation programme might be relatively low, but is modifiable by programme variables including incentive amounts. These results will be helpful to inform the design of future trials of benzodiazepine discontinuation programmes. Further research is needed to assess the financial viability and potential cost-effectiveness of such economic incentives.

A protocol for a cluster randomised feasibility study of an adolescent incentive intervention to increase uptake of HPV vaccination among girls

BACKGROUND

Uptake of the human papillomavirus (HPV) vaccine in the UK is good, but there are pockets of the community who remain unprotected. Immunisation teams usually require written parental consent for a girl to receive the vaccine. Evidence suggests that uptake of the vaccine might be improved by promoting consent form return (if returned, forms are likely to grant consent). Incentivising girls to return consent forms is a promising approach to promoting consent form return. Before testing the efficacy of an incentive intervention in a randomised controlled trial (RCT), we must first establish whether the RCT is feasible. In this randomised feasibility study, we aim to establish the feasibility of conducting a cluster RCT of an adolescent incentive intervention to increase uptake of HPV vaccination.

METHODS

At least six schools will be randomised to either an incentive intervention arm or a standard invitation arm. Girls in standard invitation arm schools will receive the usual HPV vaccine programme invitation materials. Girls attending schools in the incentive intervention arm will receive the standard invitation and will also be told that they will receive an incentive if they return their consent form (regardless of whether consent is granted or denied). The incentive is being entered into a prize draw to win a retail voucher. Feasibility objectives include estimating the schools' and parents' willingness to participate in the study and be randomised; response rates to questionnaires; the extent of missing data; the girls' and parents' attitudes towards the incentive offered; school staff experiences of participating, fidelity to the trial procedures, data on any unintended consequences and the possible mechanisms of action, and proof-of-concept evidence of the effect of the intervention on consent form return rates and uptake of the vaccine. Analysis of feasibility outcomes will primarily be descriptive. Consent form return rates and uptake of the vaccine will be presented by trial arm without comparison.

DISCUSSION

Incentivising HPV vaccine consent form return may promote HPV vaccine uptake. This study will provide the evidence needed to establish whether testing this incentive intervention using a RCT design in the future is feasible.

The Community IntraVenous Antibiotic Study (CIVAS): a mixed-methods evaluation of patient preferences for and cost-effectiveness of different service models for delivering outpatient parenteral antimicrobial therapy

Background

Outpatient parenteral antimicrobial therapy (OPAT) is widely used in most developed countries, providing considerable opportunities for improved cost savings. However, it is implemented only partially in the UK, using a variety of service models.

Objectives

The aims of this research were to (1) establish the extent of OPAT service models in England and identify their development; (2) evaluate patients’ preferences for different OPAT service delivery models; (3) assess the cost-effectiveness of different OPAT service delivery models; and (4) convene a consensus panel to consider our evidence and make recommendations.

Methods

This mixed-methods study included seven centres providing OPAT using four main service models: (1) hospital outpatient (HO) attendance; (2) specialist nurse (SN) visiting at home; (3) general nurse (GN) visiting at home; and (4) self-administration (SA) or carer administration. Health-care providers were surveyed and interviewed to explore the implementation of OPAT services in England. OPAT patients were interviewed to determine key service attributes to develop a discrete choice experiment (DCE). This was used to perform a quantitative analysis of their preferences and attitudes. Anonymised OPAT case data were used to model cost-effectiveness with both Markov and simulation modelling methods. An expert panel reviewed the evidence and made recommendations for future service provision and further research.

Results

The systematic review revealed limited robust literature but suggested that HO is least effective and SN is most effective. Qualitative study participants felt that different models of care were suited to different types of patient and they also identified key service attributes. The DCE indicated that type of service was the most important factor, with SN being strongly preferred to HO and SA. Preferences were influenced by attitudes to health care. The results from both Markov and simulation models suggest that a SN model is the optimal service for short treatment courses (up to 7 days). Net monetary benefit (NMB) values for HO, GN and SN services were £2493, £2547 and £2655, respectively. For longer treatment, SA appears to be optimal, although SNs provide slightly higher benefits at increased cost. NMB values for HO, GN, SN and SA services were £8240, £9550, £10,388 and £10,644, respectively. The simulation model provided useful information for planning OPAT services. The expert panel requested more guidance for service providers and commissioners. Overall, they agreed that mixed service models were preferable.

Limitations

Recruitment to the qualitative study was suboptimal in the very elderly and ethnic minorities, so the preferences of patients from these groups might not be represented. The study recruited from Yorkshire, so the findings may not be applicable nationally.

Conclusions

The quantitative preference analysis and economic modelling favoured a SN model, although there are differences between sociodemographic groups. SA provides cost savings for long-term treatment but is not appropriate for all.

Future work

Further research is necessary to replicate our results in other regions and populations and to evaluate mixed service models. The simulation modelling and DCE methods used here may be applicable in other health-care settings.

An interview study of pregnant women who were provided with indoor air quality measurements of second hand smoke to help them quit smoking

Background

Maternal smoking can cause health complications in pregnancy. Particulate matter (PM_2.5) metrics applied to second hand smoke (SHS) concentrations provide indoor air quality (IAQ) measurements and have been used to promote smoking behaviour change among parents of young children. Here, we present the qualitative results from a study designed to use IAQ measurements to help pregnant women who smoke to quit smoking.

Methods

We used IAQ measurements in two centres (Aberdeen and Coventry) using two interventions: 1. In Aberdeen, women made IAQ measurements in their homes following routine ultrasound scan; 2. In Coventry, IAQ measurements were added to a home-based Stop Smoking in Pregnancy Service. All women were invited to give a qualitative interview to explore acceptability and feasibility of IAQ measurements to help with smoking cessation. A case study approach using grounded theory was applied to develop a typology of pregnant women who smoke.

Results

There were 39 women recruited (18 in Aberdeen and 21 in Coventry) and qualitative interviews were undertaken with nine of those women. Diverse accounts of smoking behaviours and experiences of participation were given. Many women reported changes to their smoking behaviours during pregnancy. Most women wanted to make further changes to their own behaviour, but could not commit or felt constrained by living with a partner or family members who smoked. Others could not envisage quitting. Using themes emerging from the interviews, we constructed a typology where women were classified as follows: ‘champions for change’; ‘keen, but not committed’; and ‘can’t quit, won’t quit’. Three women reported quitting smoking alongside participation in our study.

Conclusions

Pregnant women who smoke remain hard to engage,. Although providing IAQ measurements does not obviously improve quit rates, it can support changes in smoking behaviour in/around the home for some individuals. Our typology might offer a useful assessment tool for midwives.

Breast pumps as an incentive for breastfeeding: a mixed methods study of acceptability

Increasing breastfeeding rates would improve maternal and child health, but multiple barriers to breastfeeding persist. Breast pump provision has been used as an incentive for breastfeeding, although effectiveness is unclear. Women's use of breast pumps is increasing and a high proportion of mothers express breastmilk. No research has yet reported women's and health professionals' perspectives on breast pumps as an incentive for breastfeeding. In the Benefits of Incentives for Breastfeeding and Smoking cessation in pregnancy (BIBS) study, mixed methods research explored women's and professionals' views of breast pumps as an incentive for breastfeeding. A survey of health professionals across Scotland and North West England measured agreement with ‘a breast pump costing around £40 provided for free on the NHS’ as an incentive strategy. Qualitative interviews and focus groups were conducted in two UK regions with a total of 68 participants (pregnant women, new mothers, and their significant others and health professionals) and thematic analysis undertaken. The survey of 497 health professionals found net agreement of 67.8% (337/497) with the breast pump incentive strategy, with no predictors of agreement shown by a multiple ordered logistic regression model. Qualitative research found interrelated themes of the ‘appeal and value of breast pumps’, ‘sharing the load’, ‘perceived benefits’, ‘perceived risks’ and issues related to ‘timing’. Qualitative participants expressed mixed views on the acceptability of breast pumps as an incentive for breastfeeding. Understanding the mechanisms of action for pump type, timing and additional support required for effectiveness is required to underpin trials of breast pump provision as an incentive for improving breastfeeding outcomes. © 2016 The Authors.

Combining PPI with qualitative research to engage 'harder-to-reach' populations: service user groups as co-applicants on a platform study for a trial

PLAIN ENGLISH SUMMARY

It is recommended that research studies are carried out with or by patients and the public through their involvement from the beginning and in as many stages as possible (known as PPI). Some studies formally invite patients and the public to participate in interviews and focused group discussions to collect views about topics (known as qualitative research). In our study on financial incentives for giving up smoking in pregnancy and breastfeeding, we combined both PPI and qualitative research to include the views of women with a range of experiences of smoking and breastfeeding. We involved two mother and baby groups in disadvantaged areas of North East Scotland and North West England as research partners on our team. First, we asked members to comment on our research plans and documents, which is standard PPI. Second, we asked members to participate in voice recorded discussions, contributing to qualitative research data. These discussions revealed different views from those that we heard through research interviews. They allowed us to develop more relevant research tools and resources. Members also helped us to identify people outside the groups who we could interview. Combining involvement and participation helped us to include the views of a wide range of women from 'harder-to-reach' groups who don't usually take part in research. This was important because the research was intended for women who could benefit from incentives to stop smoking in pregnancy and breastfeed, often present in such groups. Positive continuing relationships and trust improved on involvement or participation alone.

BACKGROUND

Patient and public involvement (PPI) in all research studies is recommended from the earliest point and in as many stages as possible. Qualitative research is also recommended in the early stages of designing complex intervention trials. Combining both together might enable inclusion of 'harder-to-reach' perspectives from the target population(s), particularly when the research is intended for their benefit. However, the interface between PPI and qualitative research has received little attention. In a multi-disciplinary, mixed methods study to inform the design of incentive trials for smoking cessation in pregnancy and breastfeeding, we combined PPI and qualitative research, with some overlap. Mother and baby groups from two geographically separate disadvantaged areas, with diverse experiences of the smoking and breastfeeding, but no training or previous involvement in research, were recruited as PPI research grant co-applicants. An iterative partnership approach facilitated involvement in research conduct and design across all project phases. Group PPI members were also invited to contribute to more formal qualitative data collection, as and when indicated by the research questions, and emerging analysis.

RESULTS

We engaged with 'harder-to-reach' women in mother and baby group settings, rather than in academic or home environments. These settings were relaxed and informal, which facilitated rapport-building, disclosures of unexpected information and maintained trust. Twenty-one women participated in standard PPI activities: feedback on study protocols and documents; piloting questionnaires and interview schedules. PPI members voiced some different perspectives from those captured within the qualitative dataset. Nineteen participated in focused qualitative research. Novel aspects were audio recorded PPI discussions, which contributed qualitative data; first, to interpret systematic review findings and construct intervention vignettes for use in the qualitative research; second, to assist with recruitment to improve sample diversity in the formal qualitative dataset; and third, to translate theory and findings presented in a researcher generated logic model into a lay tool. This had face validity for potential trial participants and used the metaphor of a ladder.

CONCLUSIONS

Combining and overlapping PPI and qualitative research added 'harder-to-reach' contributions, sample diversity, trust and engagement in creative approaches beyond what could be achieved through PPI or qualitative research alone.

Perspectives on financial incentives to health service providers for increasing breast feeding and smoking quit rates during pregnancy: a mixed methods study

OBJECTIVE

To explore the acceptability, mechanisms and consequences of provider incentives for smoking cessation and breast feeding as part of the Benefits of Incentives for Breastfeeding and Smoking cessation in pregnancy (BIBS) study.

DESIGN

Cross-sectional survey and qualitative interviews.

SETTING

Scotland and North West England.

PARTICIPANTS

Early years professionals: 497 survey respondents included 156 doctors; 197 health visitors/maternity staff; 144 other health staff. Qualitative interviews or focus groups were conducted with 68 pregnant/postnatal women/family members; 32 service providers; 22 experts/decision-makers; 63 conference attendees.

METHODS

Early years professionals were surveyed via email about the acceptability of payments to local health services for reaching smoking cessation in pregnancy and breastfeeding targets. Agreement was measured on a 5-point scale using multivariable ordered logit models. A framework approach was used to analyse free-text survey responses and qualitative data.

RESULTS

Health professional net agreement for provider incentives for smoking cessation targets was 52.9% (263/497); net disagreement was 28.6% (142/497). Health visitors/maternity staff were more likely than doctors to agree: OR 2.35 (95% CI 1.51 to 3.64; p<0.001). Net agreement for provider incentives for breastfeeding targets was 44.1% (219/497) and net disagreement was 38.6% (192/497). Agreement was more likely for women (compared with men): OR 1.81 (1.09 to 3.00; p=0.023) and health visitors/maternity staff (compared with doctors): OR 2.54 (95% CI 1.65 to 3.91; p<0.001). Key emergent themes were 'moral tensions around acceptability', 'need for incentives', 'goals', 'collective or divisive action' and 'monitoring and proof'. While provider incentives can focus action and resources, tensions around the impact on relationships raised concerns. Pressure, burden of proof, gaming, box-ticking bureaucracies and health inequalities were counterbalances to potential benefits.

CONCLUSIONS

Provider incentives are favoured by non-medical staff. Solutions which increase trust and collaboration towards shared goals, without negatively impacting on relationships or increasing bureaucracy are required.

How UK internet websites portray breast milk expression and breast pumps: a qualitative study of content

Background

Exclusive breastfeeding for six months is recommended but few parents achieve this; particularly younger and less well-educated mothers. Many parents introduce infant formula milk to manage feeding but describe a desire to express breastmilk alongside a lack of support or information. The Internet is highlighted as a key resource. This study aimed to examine UK websites on expressing breastmilk to identify key messages and how information is provided.

Methods

We used search terms in Google to identify websites with information rich content on expressing breastmilk and breast pumps. Ten sites were purposively selected at two time points in 2013 and 2014 to represent 3 categories: commercial, NHS or 3^rd sector (voluntary or not for profit). Each site was reviewed by two researchers, data and reflective analytical notes were uploaded into NVivo and thematic data analysis undertaken.

Results

Sites varied considerably in their design, use of images, videos, audio files, product placement and marketing opportunities. Three key themes emerged: depiction of expressing; reasons to express; and recommendations about expressing. Inconsistent and conflicting information was common within and between sites. Expressing was portrayed as similar to, but easier than, breastfeeding although at the same time difficult and requiring to be learned. Expressed breastmilk is promoted by mainly commercial sites as immediately available, although pumps were also presented as needing to be concealed, not heard or seen. Health benefits were the overarching reason for expressing. Although predicated on separation from the baby, commercial sites identified this as a positive choice while other sites focused on separation due to circumstance. Commercial sites emphasised restrictions related to breastfeeding, lack of sleep and bonding with the father and wider family. Non-commercial sites emphasised hand expression, with some not mentioning breast pumps. Practical information about starting expressing in relation to infant age or duration of breastfeeding was conflicting.

Conclusions

Internet information about expressing breastmilk is inconsistent, incomplete and not evidence informed. The lack of research evidence on the relationship between expressing and feeding outcomes has provided opportunities for commercial companies, which have the potential to further exacerbate observed health inequalities. Access to good quality information based on robust evidence is urgently required.

Unintended consequences of incentive provision for behaviour change and maintenance around childbirth

Financial (positive or negative) and non-financial incentives or rewards are increasingly used in attempts to influence health behaviours. While unintended consequences of incentive provision are discussed in the literature, evidence syntheses did not identify any primary research with the aim of investigating unintended consequences of incentive interventions for lifestyle behaviour change. Our objective was to investigate perceived positive and negative unintended consequences of incentive provision for a shortlist of seven promising incentive strategies for smoking cessation in pregnancy and breastfeeding. A multi-disciplinary, mixed-methods approach included involving two service-user mother and baby groups from disadvantaged areas with experience of the target behaviours as study co-investigators. Systematic reviews informed the shortlist of incentive strategies. Qualitative semi-structured interviews and a web-based survey of health professionals asked open questions on positive and negative consequences of incentives. The participants from three UK regions were a diverse sample with and without direct experience of incentive interventions: 88 pregnant women/recent mothers/partners/family members; 53 service providers; 24 experts/decision makers and interactive discussions with 63 conference attendees. Maternity and early years health professionals (n = 497) including doctors, midwives, health visitors, public health and related staff participated in the survey. Qualitative analysis identified ethical, political, cultural, social and psychological implications of incentive delivery at population and individual levels. Four key themes emerged: how incentives can address or create inequalities; enhance or diminish intrinsic motivation and wellbeing; have a positive or negative effect on relationships with others within personal networks or health providers; and can impact on health systems and resources by raising awareness and directing service delivery, but may be detrimental to other health care areas. Financial incentives are controversial and generated emotive and oppositional responses. The planning, design and delivery of future incentive interventions should evaluate unexpected consequences to inform the evidence for effectiveness, cost-effectiveness and future implementation.

Public acceptability of financial incentives for smoking cessation in pregnancy and breast feeding: a survey of the British public

OBJECTIVE

To survey public attitudes about incentives for smoking cessation in pregnancy and for breast feeding to inform trial design.

DESIGN

Cross-sectional survey.

SETTING AND PARTICIPANTS

British general public.

METHODS

Seven promising incentive strategies had been identified from evidence syntheses and qualitative interview data from service users and providers. These were shopping vouchers for: (1) validated smoking cessation in pregnancy and (2) after birth; (3) for a smoke-free home; (4) for proven breast feeding; (5) a free breast pump; (6) payments to health services for reaching smoking cessation in pregnancy targets and (7) breastfeeding targets. Ipsos MORI used area quota sampling and home-administered computer-assisted questionnaires, with randomised question order to assess agreement with different incentives (measured on a five-point scale). Demographic data and target behaviour experience were recorded. Analysis used multivariable ordered logit models.

RESULTS

Agreement with incentives was mixed (ranging from 34% to 46%) among a representative sample of 1144 British adults. Mean agreement score was highest for a free breast pump, and lowest for incentives for smoking abstinence after birth. More women disagreed with shopping vouchers than men. Those with lower levels of education disagreed more with smoking cessation incentives and a breast pump. Those aged 44 or under agreed more with all incentive strategies compared with those aged 65 and over, particularly provider targets for smoking cessation. Non-white ethnic groups agreed particularly with breastfeeding incentives. Current smokers with previous stop attempts and respondents who had breast fed children agreed with providing vouchers for the respective behaviours. Up to £40/month vouchers for behaviour change were acceptable (>85%).

CONCLUSIONS

Women and the less educated were more likely to disagree, but men and women of childbearing age to agree, with incentives designed for their benefit. Trials evaluating reach, impact on health inequalities and ethnic groups are required prior to implementing incentive interventions.
