Exploring the experiences of pregnant women using an NHS stop smoking service: a qualitative study

Exploring pregnant women's experiences of stopping smoking with an incentive scheme with 'enhanced' support: a qualitative study

AIM

This study aims to understand pregnant women's experiences of smoking cessation with an incentive scheme in a deprived UK city. This is important because smoking cessation with pregnant women is one of the most crucial public health initiatives to promote, and is particularly challenging in deprived areas. While financial incentive schemes are controversial, there is a need to better understand pregnant women's experiences. The scheme combined quasi-financial incentives (shopping vouchers) for validated quits (carbon monoxide (CO) validated at < 10 ppm), enhanced support from smoking cessation advisors, the opportunity to identify a 'Significant Other Supporter' and nicotine replacement therapy.

METHODS

With the focus on understanding pregnant women's experiences, a qualitative design was adopted. Semi-structured interviews were completed with 12 pregnant women from the scheme, and the three advisors. All interviews were transcribed, and thematic analysis conducted.

RESULTS

Pregnant women reported various challenges to quitting, including long-established routines, and stress. Participants were aware of stigma around incentives but were all very positive about the scheme. The relationship with advisors was described as fundamental. The women valued their advice and support, while uptake of the 'Significant Other Supporter' appeared low. Participants viewed the CO monitoring as 'an incentive', while the vouchers were framed as a 'bonus'. Advisors perceived the vouchers as helping engage pregnant women and maintain quit status, and women appreciated the vouchers both as financial assistance and recognition of their accomplishments.

CONCLUSION

This study highlights the great value women placed on the support, advice and monitoring from specialist advisors. The distinction between vouchers as a welcomed bonus, rather than 'the incentive' to engage, is important. How smoking cessation and schemes to promote this are communicated to pregnant women and health professionals is important, particularly given the stigma and controversy involved.

Understanding willingness to access and experiences of NHS Stop Smoking Services: a qualitative systematic review with meta-aggregation synthesis

OBJECTIVES

NHS Stop Smoking Services (NHS-SSS) have been available in the United Kingdom (UK) since 2000. The service has proven to be effective, however uptake remains below aspirations. Understanding people's willingness and reasons for accessing and engaging with NHS-SSS is, therefore, important. The aim of this systematic review is to summarise the findings from qualitative research to understand people's views, perceptions and willingness to access NHS-SSS.

STUDY DESIGN

Qualitative systematic review with meta-aggregation synthesis.

METHODS

Four electronic databases were searched for published qualitative studies, from Jan 2000 to Jan 2020. Following the screening, data extraction and quality assessment, data synthesis was conducted using meta-aggregation based on a patient-centred theoretical framework. We explored five 'demand-side' dimensions of service accessibility: the ability to perceive, seek, reach, pay and engage. Confidence in the synthesised findings relating to dependability and credibility was established using CONQual.

RESULTS

Seventeen studies were included in the review. Twelve categories emerged, contributing to five synthesised statements, all with a CONQual rating of moderate confidence. Access and willingness to use NHS-SSS were found to be related to an individual's readiness to perceive that smoking is a problem for which a solution should be sought, their ability to seek a perceived effective treatment, to conveniently reach NHS-SSS, their perceptions around associated costs and tailoring care to improve engagement with individuals.

CONCLUSIONS

By using a theoretical framework incorporating healthcare access, this study provides policymakers valuable insights into people's willingness to access these services. Willingness to access NHS-SSS is multifaceted, nuanced and complex. Strategies to promote NHS-SSS uptake should include making services more attractive, relevant and responsive to individual perceptions around smoking and health. Given the higher prevalence of smoking in less affluent socioeconomic groups and in some ethnic minority groups, the importance of having a comprehensive and inclusive tobacco control policy, one that is linguistically and culturally sensitive, cannot be overstated.

Factors influencing the uptake and use of nicotine replacement therapy and e-cigarettes in pregnant women who smoke: a qualitative evidence synthesis

BACKGROUND

Nicotine replacement therapy (NRT) delivers nicotine without the toxic chemicals present in tobacco smoke. It is an effective smoking cessation aid in non-pregnant smokers, but there is less evidence of effectiveness in pregnancy. Systematic review evidence suggests that pregnant women do not adhere to NRT as prescribed, which might undermine effectiveness. Electronic cigarettes (e-cigarettes) have grown in popularity, but effectiveness and safety in pregnancy are not yet established. The determinants of uptake and use of NRT and e-cigarettes in pregnancy are unknown.

OBJECTIVES

To explore factors affecting uptake and use of NRT and e-cigarettes in pregnancy.

SEARCH METHODS

We searched MEDLINE(R), CINAHL and PsycINFO on 1 February 2019. We manually searched OpenGrey database and screened references of included studies and relevant reviews. We also conducted forward citation searches of included studies.

SELECTION CRITERIA

We selected studies that used qualitative methods of data collection and analysis, included women who had smoked in pregnancy, and elicited participants' views about using NRT/e-cigarettes for smoking cessation or harm reduction (i.e. to smoke fewer cigarettes) during pregnancy.

DATA COLLECTION AND ANALYSIS

We identified determinants of uptake and use of NRT/e-cigarettes in pregnancy using a thematic synthesis approach. Two review authors assessed the quality of included studies with the Wallace tool. Two review authors used the CERQual approach to assess confidence in review findings. The contexts of studies from this review and the relevant Cochrane effectiveness review were not similar enough to fully integrate findings; however, we created a matrix to juxtapose findings from this review with the descriptions of behavioural support from trials in the effectiveness review.

MAIN RESULTS

We included 21 studies: 15 focused on NRT, 3 on e-cigarettes, and 3 on both. Studies took place in five high-income countries. Most studies contributed few relevant data; substantially fewer data were available on determinants of e-cigarettes. Many studies focused predominantly on issues relating to smoking cessation, and determinants of NRT/e-cigarette use was often presented as one of the themes. We identified six descriptive themes and 18 findings within those themes; from these we developed three overarching analytical themes representing key determinants of uptake and adherence to NRT and/or e-cigarettes in pregnancy. The analytical themes show that women's desire to protect their unborn babies from harm is one of the main reasons they use these products. Furthermore, women consider advice from health professionals when deciding whether to use NRT or e-cigarettes; when health professionals tell women that NRT or e-cigarettes are safer than smoking and that it is okay for them to use these in pregnancy, women report feeling more confident about using them. Conversely, women who are told that NRT or e-cigarettes are as dangerous or more dangerous than smoking and that they should not use them during pregnancy feel less confident about using them. Women's past experiences with NRT can also affect their willingness to use NRT in pregnancy; women who feel that NRT had worked for them (or someone they know) in the past were more confident about using it again. However, women who had negative experiences were more reluctant to use NRT. No trials on e-cigarette use in pregnancy were included in the Cochrane effectiveness review, so we considered only NRT findings when integrating results from this review and the effectiveness review. No qualitative studies were conducted alongside trials, making full integration of the findings challenging. Women enrolled in trials would have agreed to being allocated to NRT or control group and would have received standardised information on NRT at the start of the trial. Overall, the findings of this synthesis are less relevant to women's decisions about starting NRT in trials and more likely to help explain trial participants' adherence to NRT after starting it. We considered most findings to be of moderate certainty; we assessed findings on NRT use as being of higher certainty than those on e-cigarette use. This was mainly due to the limited data from fewer studies (only in the UK and USA) that contributed to e-cigarette findings. Overall, we judged studies to be of acceptable quality with only minor methodological issues.

AUTHORS' CONCLUSIONS

Consistent messages from health professionals, based on high-quality evidence and clearly explaining the safety of NRT and e-cigarettes compared to smoking in pregnancy, could help women use NRT and e-cigarettes more consistently/as recommended. This may improve their attitudes towards NRT or e-cigarettes, increase their willingness to use these in their attempt to quit, and subsequently encourage them to stay smoke-free.

Pregnant Smokers' Experiences and Opinions of Techniques Aimed to Address Barriers and Facilitators to Smoking Cessation: A Qualitative Study

Pregnant women experience certain barriers and facilitators (B&Fs) when trying to quit smoking. This study aimed to elicit women’s views on techniques that could help overcome or enhance these. Semi-structured interviews were conducted with 12 pregnant women who had experience of smoking during pregnancy. Participants were prompted to discuss experiences of B&Fs and give suggestions of techniques that could address these appropriately. A thematic analysis was conducted using the one sheet of paper method. Four themes relating to suggested techniques were identified: accessing professional help, nicotine replacement therapy (NRT), distraction, and social interactions. Experiences of accessing professional help were generally positive, especially if there was a good rapport with, and easy access to a practitioner. Most women were aware of NRT, those who had used it reported both negative and positive experiences. Praise and encouragement from others towards cessation attempts appeared motivating; peer support groups were deemed useful. Women reported experiencing B&Fs which fell under four themes: influence of others, internal motivation, cues to smoke, and health. Overall, accessing professional support generated positive changes in smoking habits. Establishing ways of how to encourage more women to seek help and raising awareness of different types of support available would seem beneficial.

Are digital interventions for smoking cessation in pregnancy effective? A systematic review protocol

BACKGROUND

Behavioural support for smoking cessation in pregnancy can be effective; however, many pregnant women face barriers to seeking support to stop smoking. Some digital interventions have been found to be effective for smoking cessation in the general population and may be effective for supporting cessation in pregnancy due to their flexibility and the potential for personalisation. To date, there is limited evidence of the effectiveness of digital interventions for smoking cessation in pregnancy. This review aims to assess the following: (1) whether digital interventions are effective at promoting smoking cessation among pregnant women; (2) which behaviour change techniques (BCTs) or combinations of BCTs are associated with the effectiveness of digital interventions for smoking cessation in pregnancy; and (3) whether the number of BCTs used is associated with the effectiveness of digital interventions for smoking cessation in pregnancy.

METHODS

This review will include digital interventions delivered largely through computer (PC or laptop), video/DVD, mobile phone (including smartphones) or portable handheld device (e.g. tablet, iPad) and include websites, mobile or tablet applications and SMS text messages. Interventions must be randomised or quasi-randomised controlled trials aimed at women who smoke in pregnancy, with smoking cessation as a measured outcome (preferably the latest available point prevalence smoking status measure taken during pregnancy, biochemically verified if available). Electronic bibliographic databases will be searched to identify suitable studies indexed in the following: Academic Search Complete, ASSIA, CINAHL, The Cochrane Library, EMBASE, Medline, PsycINFO, Scopus, and Web of Science. The search strategy will include key words and database-specific subject headings relating to 'pregnancy' and 'smoking' and synonyms for the terms 'digital' and 'randomised controlled trial'. Where required and where possible, the first and second authors will independently code interventions and control groups for BCTs. If data allows, meta-analyses will be used to assess intervention effectiveness and the effectiveness of BCTs.

DISCUSSION

This systematic review will provide a detailed synthesis of the effectiveness of current research using digital interventions for smoking cessation in pregnancy, to build on the evidence base and guide the development of future research in this area.

Preventing Obesity Across Generations: Evidence for Early Life Intervention

To prevent the intergenerational transfer of obesity and end the current epidemic, interventions are needed across the early life stages, from preconception to prenatal to infancy through the age of 2 years. The foundation for obesity is laid in early life by actions and interactions passed from parent to child that have long-lasting biologic and behavioral consequences. The purpose of this paper is to examine the best evidence about (a) factors in parents and offspring that promote obesity during the early life stages, (b) the social determinants and dimensions of obesity in early life, (c) promising and effective interventions for preventing obesity in early life, and (d) opportunities for future research into strategies to disrupt the intergenerational cycle of obesity that begins early in life. The pathway for halting the intergenerational obesity epidemic requires the discovery and development of evidence-based interventions that can act across multiple dimensions of influence on early life.

Understanding Pregnant Smokers' Adherence to Nicotine Replacement Therapy During a Quit Attempt: A Qualitative Study

BACKGROUND

Pregnant smokers may be offered nicotine replacement therapy (NRT) alongside behavioral support to assist with a quit attempt. Yet trials of NRT have found adherence to be low among pregnant women, and this has made it difficult to determine the efficacy of NRT. The aim of this study is to understand the experience of pregnant women who use NRT but discontinue this early or do not use the medication as recommended.

METHODS

Semi-structured telephone interviews were conducted with 14 pregnant smokers who had recently been prescribed NRT, but self-reported poor NRT adherence or discontinuing treatment prematurely. Data were transcribed and analyzed using inductive thematic analysis

RESULTS

There were four main themes identified; expectations of NRT, experience of using NRT, safety concerns and experience of using e-cigarettes. Some women intentionally used NRT to substitute a proportion of their cigarette intake and smoked alongside. Most women smoked while using NRT. Women who underutilized NRT did so as they experienced side effects, or were concerned that using NRT instead of smoking could actually increase their nicotine exposure and potential for increased nicotine dependence or fetal harm. Most women spoke about the use of e-cigarettes as a smoking cessation method but only a few had actually experienced using them during pregnancy.

CONCLUSION

Many women underused NRT but simultaneously smoked. Challenging negative perceptions about NRT and educating women further about the risks of smoking may encourage them to use NRT products as recommended.

IMPLICATIONS

These findings add to the research surrounding the efficacy of NRT during pregnancy by providing insight into how pregnant women use NRT during a quit attempt and how this may influence adherence. It may assist health professionals to support pregnant smokers by increasing their understanding about the differing ways in which women use NRT and help them address concerns women may have about the safety of NRT.
