An effective patient-supporting intervention for topical treatment of psoriasis is also cost-effective. Clin Exp Dermatol 2023; 48:1247-1254. [PMID: 37585448 DOI: 10.1093/ced/llad272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 06/18/2023] [Accepted: 08/10/2023] [Indexed: 08/18/2023]
Abstract
BACKGROUND A randomized controlled trial (RCT) of topical treatment combined with regular patient support provided by dermatological nurses in structured consultations of 20-min duration every fourth week improved psoriasis severity, quality of life and treatment adherence compared with topical treatment combined with standard patient support, which is seeing a dermatologist every third month. OBJECTIVES To examine the economic impact of the patient support from a healthcare-sector perspective in the RCT. METHODS Costs for primary care, secondary healthcare services and costs of prescription medication were compared for the intervention and nonintervention groups over 48 weeks. Health benefits were expressed in terms of quality-adjusted life-years (QALYs) measured by the EuroQoL five-dimension three-level questionnaire. Regression analyses were used to estimate incremental cost and QALYs. RESULTS The incremental cost was estimated at £462, with an average increase of 0.08 QALYs per patients for participants receiving the intervention compared with those receiving standard care. The incremental cost-effectiveness ratio for patients was £5999/QALY. The intervention had an almost 100% probability of being cost-effective at a willingness-to-pay threshold of £30 000 per QALY. CONCLUSIONS Addressing adherence issues is critical to improving outcomes for patients with psoriasis who use topical treatment. The personal support intervention was effective with an acceptable increase in costs.

Cost-effectiveness of a motivational interviewing obesity intervention versus usual care in pediatric primary care offices. Obesity (Silver Spring) 2022; 30:2265-2274. [PMID: 36321279 PMCID: PMC9828545 DOI: 10.1002/oby.23560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 07/25/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVE This study aimed to assess the incremental cost-effectiveness ratio (ICER) of a 2-year motivational interviewing (MI) intervention versus usual primary care. METHODS A national trial was implemented in the Pediatric Research in Office Settings (PROS) network of the American Academy of Pediatrics to evaluate MI versus usual care for children (2-8 years old; baseline BMI 85th-97th percentiles). Health care use, food costs, provider fees, and training costs were assessed, and sensitivity analyses were conducted. Primary outcome was the ICER, calculated as cost per unit change in BMI percentile for intervention versus usual care. RESULTS At 2 years, 72% of enrolled parent/child dyads were retained; 312 children were included in the analysis. Mean BMI percentile point change was -4.9 and -1.8 for the intervention and control, respectively, yielding an incremental reduction of 3.1 BMI percentile points (95% CI: 1.2-5.0). The intervention cost $1051 per dyad ($658 for training DVD development). Incorporating health care and non-health care costs, the intervention ICER was $363 (range from sensitivity analyses: cost saving, $3159) per BMI percentile point decrease per participant over 2 years. CONCLUSIONS Training pediatricians, nurse practitioners, and registered dietitians to deliver MI-based interventions for childhood obesity in primary care is clinically effective and acceptably cost-effective. Future work should explore this approach in broader dissemination.

Abstract
Background Many hospitalized patients are not administered prescribed doses of pharmacologic venous thromboembolism prophylaxis. Methods and Results In this cluster-randomized controlled trial, all adult non-intensive care units (10 medical, 6 surgical) in 1 academic hospital were randomized to either a real-time, electronic alert-triggered, patient-centered education bundle intervention or nurse feedback intervention to evaluate their effectiveness for reducing nonadministration of venous thromboembolism prophylaxis. Primary outcome was the proportion of nonadministered doses of prescribed pharmacologic prophylaxis. Secondary outcomes were proportions of nonadministered doses stratified by nonadministration reasons (patient refusal, other). To test our primary hypothesis that both interventions would reduce nonadministration, we compared outcomes pre- versus postintervention within each cohort. Secondary hypotheses were tested comparing the effectiveness between cohorts. Of 11 098 patient visits, overall dose nonadministration declined significantly after the interventions (13.4% versus 9.2%; odds ratio [OR], 0.64 [95% CI, 0.57-0.71]). Nonadministration decreased significantly (P<0.001) in both arms: patient-centered education bundle, 12.2% versus 7.4% (OR, 0.56 [95% CI, 0.48-0.66]), and nurse feedback, 14.7% versus 11.2% (OR, 0.72 [95% CI, 0.62-0.84]). Patient refusal decreased significantly in both arms: patient-centered education bundle, 7.3% versus 3.7% (OR, 0.46 [95% CI, 0.37-0.58]), and nurse feedback, 9.5% versus 7.1% (OR, 0.71 [95% CI, 0.59-0.86]). No differential effect occurred on medical versus surgical units. The patient-centered education bundle was significantly more effective in reducing all nonadministered (P=0.03) and refused doses (P=0.003) compared with nurse feedback (OR, 1.28 [95% CI, 1.0-1.61]; P=0.03 for interaction). Conclusions Information technology strategies like the alert-triggered, targeted patient-centered education bundle, and nurse-focused audit and feedback can improve venous thromboembolism prophylaxis administration.

Abstract
Background Online health data collection has gained a reputation over the last years to record and process information about health issues for implementing digital health. Objective The research aim was to appraise two online methods (open and rewarded) to collect information about HRQoL and nutritional well-being and to compare the results between both surveyed populations. Methods This cross-sectional study is framed on the NUTRiMDEA project. Online data through two different web-based methods (open survey and rewarded survey) were retrieved to assemble data related to sociodemographic, lifestyle (diet, physical activity and sleep patterns) and general health aspects, as well as HRQoL by an evidence-based form such as the SF-12 questionnaire, the IPAQ survey, and MEDAS-14, participants were adults (>18 years old). Results Overall, 17,332 participants responded to the open survey (OS, n = 11,883) or the rewarded survey (RS, n = 5449). About 65.1% of the participants were female, while the mean age was in the range of 40–70 years. There were significant differences ( p < 0.05) between surveyed populations in sociodemographic, lifestyle (diet and physical activity), health and HRQoL data. Conclusions This investigation implemented an evidence-based online questionnaire that collected demographic, lifestyle factors, phenotypic and health-related aspects as well as compared differential outcomes in HRQoL and nutritional/lifestyle well-being depending on the online mode data collection. Findings demonstrated dissimilarities in most aspects of health, HRQoL, dietary intake and physical activity records between both populations. Overall, OS sample was characterized as a healthier population with superior lifestyle habits than RS participants.

Promoting physical activity and physical function in people with long-term conditions in primary care: the Function First realist synthesis with co-design. HEALTH SERVICES AND DELIVERY RESEARCH 2021. [DOI: 10.3310/hsdr09160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022] Open
Abstract
Background
As people age and accumulate long-term conditions, their physical activity and physical function declines, resulting in disability and loss of independence. Primary care is well placed to empower individuals and communities to reduce this decline; however, the best approach is uncertain.
Objectives
To develop a programme theory to explain the mechanisms through which interventions improve physical activity and physical function in people with long-term conditions in different primary care contexts, and to co-design a prototype intervention.
Data sources
Systematic literature searches of relevant databases with forwards and backwards citation tracking, grey literature searches and further purposive searches were conducted. Qualitative data were collected through workshops and interviews.
Design
Realist evidence synthesis and co-design for primary care service innovation.
Setting
Primary care in Wales and England.
Participants
Stakeholders included people with long-term conditions, primary care professionals, people working in relevant community roles and researchers.
Methods
The realist evidence synthesis combined evidence from varied sources of literature with the views, experiences and ideas of stakeholders. The resulting context, mechanism and outcome statements informed three co-design workshops and a knowledge mobilisation workshop for primary care service innovation.
Results
Five context, mechanism and outcome statements were developed. (1) Improving physical activity and function is not prioritised in primary care (context). If the practice team culture is aligned to the elements of physical literacy (mechanism), then physical activity promotion will become routine and embedded in usual care (outcome). (2) Physical activity promotion is inconsistent and unco-ordinated (context). If specific resources are allocated to physical activity promotion (in combination with a supportive practice culture) (mechanism), then this will improve opportunities to change behaviour (outcome). (3) People with long-term conditions have varying levels of physical function and physical activity, varying attitudes to physical activity and differing access to local resources that enable physical activity (context). If physical activity promotion is adapted to individual needs, preferences and local resources (mechanism), then this will facilitate a sustained improvement in physical activity (outcome). (4) Many primary care practice staff lack the knowledge and confidence to promote physical activity (context). If staff develop an improved sense of capability through education and training (mechanism), then they will increase their engagement with physical activity promotion (outcome). (5) If a programme is credible with patients and professionals (context), then trust and confidence in the programme will develop (mechanism) and more patients and professionals will engage with the programme (outcome). A prototype multicomponent intervention was developed. This consisted of resources to nurture a culture of physical literacy, materials to develop the role of a credible professional who can promote physical activity using a directory of local opportunities and resources to assist with individual behaviour change.
Limitations
Realist synthesis and co-design is about what works in which contexts, so these resources and practice implications will need to be modified for different primary care contexts.
Conclusions
We developed a programme theory to explain how physical activity could be promoted in primary care in people with long-term conditions, which informed a prototype intervention.
Future work
A future research programme could further develop the prototype multicomponent intervention and assess its acceptability in practice alongside existing schemes before it is tested in a feasibility study to inform a future randomised controlled trial.

Abstract
Volunteers have been extensively used in health promotion programmes. However, they have been less frequently involved in the research process. In its most recent iterations, the Cardiovascular Health Awareness Program (CHAP) integrated volunteers (i) to facilitate CHAP sessions with participating patients for data collection and (ii) to evaluate the intervention. Drawing on the patient and public involvement literature, our research team included volunteers in the data collection and evaluation of CHAP sessions as part of the programme's implementation in the province of Quebec (Canada). We sought volunteers' formal feedback through individual online and phone interviews and through focus groups for each of the four projects conducted in Quebec. We found that volunteers provide valuable insight on the research protocol as well as patient needs. Their feedback led to several modifications to the research protocol and procedures of subsequent CHAP sessions. Changes included involving volunteers at earlier stages of the research process, adding more learning modules and practice sessions during the volunteer training and defining research priorities according to patient needs. Our methodology of engaging volunteers in the research process was useful to gain important and unique insight on patient needs and for future programme planning to modify the research process.

'Function First': how to promote physical activity and physical function in people with long-term conditions managed in primary care? A study combining realist and co-design methods. BMJ Open 2021; 11:e046751. [PMID: 34315792 PMCID: PMC8317101 DOI: 10.1136/bmjopen-2020-046751] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 05/13/2021] [Indexed: 02/06/2023] Open
Abstract
OBJECTIVES To develop a taxonomy of interventions and a programme theory explaining how interventions improve physical activity and function in people with long-term conditions managed in primary care. To co-design a prototype intervention informed by the programme theory. DESIGN Realist synthesis combining evidence from a wide range of rich and relevant literature with stakeholder views. Resulting context, mechanism and outcome statements informed co-design and knowledge mobilisation workshops with stakeholders to develop a primary care service innovation. RESULTS A taxonomy was produced, including 13 categories of physical activity interventions for people with long-term conditions. ABRIDGED REALIST PROGRAMME THEORY Routinely addressing physical activity within consultations is dependent on a reinforcing practice culture, and targeted resources, with better coordination, will generate more opportunities to address low physical activity. The adaptation of physical activity promotion to individual needs and preferences of people with long-term conditions helps affect positive patient behaviour change. Training can improve knowledge, confidence and capability of practice staff to better promote physical activity. Engagement in any physical activity promotion programme will depend on the degree to which it makes sense to patients and professions, and is seen as trustworthy. CO-DESIGN The programme theory informed the co-design of a prototype intervention to: improve physical literacy among practice staff; describe/develop the role of a physical activity advisor who can encourage the use of local opportunities to be more active; and provide materials to support behaviour change. CONCLUSIONS Previous physical activity interventions in primary care have had limited effect. This may be because they have only partially addressed factors emerging in our programme theory. The co-designed prototype intervention aims to address all elements of this emergent theory, but needs further development and consideration alongside current schemes and contexts (including implications relevant to COVID-19), and testing in a future study. The integration of realist and co-design methods strengthened this study.

Cost-effectiveness evidence for strategies to promote or support breastfeeding: a systematic search and narrative literature review. BMC Pregnancy Childbirth 2020; 20:757. [PMID: 33272225 PMCID: PMC7712610 DOI: 10.1186/s12884-020-03460-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Accepted: 11/25/2020] [Indexed: 11/25/2022] Open
Abstract
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.

Collaboration for Impact: Co-creating a Workforce Development Toolkit Using an Arts-based Approach. Int J Integr Care 2020; 20:11. [PMID: 32565761 PMCID: PMC7292144 DOI: 10.5334/ijic.5377] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Accepted: 05/13/2020] [Indexed: 11/20/2022] Open
Abstract
INTRODUCTION The identification, communication and management of health risk is a core task of Community Health Workers who operate at the boundaries of community and primary care, often through not-for-profit community interest companies. However, there are few opportunities or resources for workforce development. Publicly funded researchers have an obligation to be useful to the public and furthermore, university funding is increasingly contingent on demonstrating the social impact of academic research. Collaborative work with participants and other stakeholders can have reciprocal benefits to all but may be daunting to some researchers, unused to such approaches. METHODS This case study is an account of the co-creation of a (freely accessible) workforce development toolkit, as part of a collaboration between academics, community interest companies, patients and services users and arts practitioners. RESULTS Our collaborative group produced three short films, fictionalising encounters between Community Health Workers and their clients. These were used within a series of five discussion-led workshops with facilitator guidance to explore issues generated by the films. Two collaborating community-based, not-for-profit organisations piloted the toolkit before its launch. CONCLUSION We aim to encourage other academics to maximise the impact of their own research through collaborative projects with those outside of academia, including research participants and to consider the potential value of arts-based approaches to explore and facilitate reflection on complex tasks and tensions that make up daily work practices. Whilst publication of findings from such projects may be commonplace, accounts of the process are unusual. This detailed account highlights some of the benefits and challenges involved.

Cost-effectiveness of Imaging Protocols for Suspected Appendicitis. Pediatrics 2020; 145:peds.2019-1352.

Abstract
BACKGROUND Inaccurate diagnosis of appendicitis leads to increased costs and morbidity. Ultrasound costs less than computed tomography (CT) or MRI but has lower sensitivity and may not visualize the appendix. METHODS We conducted a cost-effectiveness analysis using a decision-analytic model of 10 imaging strategies for suspected appendicitis in a hypothetical cohort of patients: no imaging with discharge or surgery; CT only; MRI only; or staged approach with CT or MRI after 1) negative ultrasound result or ultrasound without appendix visualization, 2) ultrasound without appendix visualization, or 3) ultrasound without appendix visualization but with secondary signs of inflammation. Inputs were derived from published literature and secondary data (quality-of-life and cost data). Sensitivity analyses varied risk of appendicitis and proportion of visualized ultrasound. Outcomes were effectiveness (quality-adjusted life-years [QALYs]), total direct medical costs, and cost-effectiveness (cost per QALY gained). RESULTS The most cost-effective strategy for patients at moderate risk for appendicitis is initial ultrasound, followed by CT if the appendix is not visualized but secondary signs are present (cost of $4815.03; effectiveness of 0.99694 QALYs). Other strategies were well above standard willingness-to-pay thresholds or were more costly and less effective. Cost-effectiveness was sensitive to patients' risk of appendicitis but not the proportion of visualized appendices. CONCLUSIONS Tailored approaches to imaging based on patients' risk of appendicitis are the most cost-effective. Imaging is not cost-effective in patients with a probability <16% or >95%. For moderate-risk patients, ultrasound without secondary signs of inflammation is sufficient even without appendix visualization.

Abstract
BACKGROUND Motivational interviewing (MI) enhanced with behaviour change techniques (BCTs) and deployed by health trainers targeting multiple risk factors for cardiovascular disease (CVD) may be more effective than interventions targeting a single risk factor. OBJECTIVES The clinical effectiveness and cost-effectiveness of an enhanced lifestyle motivational interviewing intervention for patients at high risk of CVD in group settings versus individual settings and usual care (UC) in reducing weight and increasing physical activity (PA) were tested. DESIGN This was a three-arm, single-blind, parallel randomised controlled trial. SETTING A total of 135 general practices across all 12 South London Clinical Commissioning Groups were recruited. PARTICIPANTS A total of 1742 participants aged 40-74 years with a ≥ 20.0% risk of a CVD event in the following 10 years were randomised. INTERVENTIONS The intervention was designed to integrate MI and cognitive-behavioural therapy (CBT), delivered by trained healthy lifestyle facilitators in 10 sessions over 1 year, in group or individual format. The control group received UC. RANDOMISATION Simple randomisation was used with computer-generated randomisation blocks. In each block, 10 participants were randomised to the group, individual or UC arm in a 4 : 3 : 3 ratio. Researchers were blind to the allocation. MAIN OUTCOME MEASURES The primary outcomes are change in weight (kg) from baseline and change in PA (average number of steps per day over 1 week) from baseline at the 24-month follow-up, with an interim follow-up at 12 months. An economic evaluation estimates the relative cost-effectiveness of each intervention. Secondary outcomes include changes in low-density lipoprotein cholesterol and CVD risk score. RESULTS The mean age of participants was 69.75 years (standard deviation 4.11 years), 85.5% were male and 89.4% were white. At the 24-month follow-up, the group and individual intervention arms were not more effective than UC in increasing PA [mean 70.05 steps, 95% confidence interval (CI) -288 to 147.9 steps, and mean 7.24 steps, 95% CI -224.01 to 238.5 steps, respectively] or in reducing weight (mean -0.03 kg, 95% CI -0.49 to 0.44 kg, and mean -0.42 kg, 95% CI -0.93 to 0.09 kg, respectively). At the 12-month follow-up, the group and individual intervention arms were not more effective than UC in increasing PA (mean 131.1 steps, 95% CI -85.28 to 347.48 steps, and mean 210.22 steps, 95% CI -19.46 to 439.91 steps, respectively), but there were reductions in weight for the group and individual intervention arms compared with UC (mean -0.52 kg, 95% CI -0.90 to -0.13 kg, and mean -0.55 kg, 95% CI -0.95 to -0.14 kg, respectively). The group intervention arm was not more effective than the individual intervention arm in improving outcomes at either follow-up point. The group and individual interventions were not cost-effective. CONCLUSIONS Enhanced MI, in group or individual formats, targeted at members of the general population with high CVD risk is not effective in reducing weight or increasing PA compared with UC. Future work should focus on ensuring objective evidence of high competency in BCTs, identifying those with modifiable factors for CVD risk and improving engagement of patients and primary care.

Quantifying changes in global health inequality: the Gini and Slope Inequality Indices applied to the Global Burden of Disease data, 1990-2017. BMJ Glob Health 2019; 4:e001500. [PMID: 31637024 PMCID: PMC6768361 DOI: 10.1136/bmjgh-2019-001500] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2019] [Revised: 07/14/2019] [Accepted: 07/15/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The major shifts in the global burden of disease over the past decades are well documented, but how these shifts have affected global inequalities in health remains an underexplored topic. We applied comprehensive inequality measures to data from the Global Burden of Disease (GBD) study. METHODS Between-country relative inequality was measured by the population-weighted Gini Index, between-country absolute inequality was calculated using the population-weighted Slope Inequality Index (SII). Both were applied to country-level GBD data on age-standardised disability-adjusted life years. FINDINGS Absolute global health inequality measured by the SII fell notably between 1990 (0.68) and 2017 (0.42), mainly driven by a decrease of disease burden due to communicable, maternal, neonatal and nutritional diseases (CMNN). By contrast, relative inequality remained essentially unchanged from 0.21 to 0.19 (1990-2017), with a peak of 0.23 (2000-2008). The main driver for the increase of relative inequality 1990-2008 was the HIV epidemic in Sub-Saharan Africa. Relative inequality increased 1990-2017 within each of the three main cause groups: CMNNs; non-communicable diseases (NCDs); and injuries. CONCLUSIONS Despite considerable reductions in disease burden in 1990-2017 and absolute health inequality between countries, absolute and relative international health inequality remain high. The limited reduction of relative inequality has been largely due to shifts in disease burden from CMNNs and injuries to NCDs. If progress in the reduction of health inequalities is to be sustained beyond the global epidemiological transition, the fight against CMNNs and injuries must be joined by increased efforts for NCDs.

Abstract
The aim of this study was to systematically review lay health worker (LHW)-led self-management interventions for adults with long-term conditions to see how the interventions have been implemented and to compose a synthesis of research findings, taking into consideration the intervention components that have been applied. We conducted systematic searches for articles published between January 2010 and December 2015 in five databases: Cochrane, MEDLINE, CINAHL, PsycINFO, and Web of Science. Forty original studies were found that met the inclusion criteria: self-management with diabetes (n = 29), cardiovascular diseases (n = 8), and those at risk of cardiovascular diseases (n = 3). These consisted of 22 randomized controlled trials and 18 other trials, with durations of 1 day to 24 months. The findings showed that the training of LHWs and the implementation of interventions varied widely. A synthesis of the implementation methods covers the background of the LHWs and the interventions as well as the components applied in each. Eight interventions had effects on physical activity and eight on nutrition behavior. The review also includes preliminary findings on intervention components effective in improving physical activity and nutrition behavior, including self-monitoring as a behavior change technique and group meetings as an intervention format. The same components and behavior change techniques were applied in effective and noneffective interventions. The review found that LHW-led interventions have potential in promoting self-management in long-term condition. In the future, a qualified and evidence-based structure for LHW-led interventions is suggested in order to improve the systematization of interventions and their effects.

Risk work or resilience work? A qualitative study with community health workers negotiating the tensions between biomedical and community-based forms of health promotion in the United Kingdom. PLoS One 2019; 14:e0220109. [PMID: 31356605 PMCID: PMC6662997 DOI: 10.1371/journal.pone.0220109] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Accepted: 07/09/2019] [Indexed: 12/02/2022] Open
Abstract
Emplaced health promotion interventions, delivered by community health workers are increasingly being used internationally. However, the application of epidemiological risk knowledge to individuals within such communities is not straightforward and creates tensions for community health workers who are part of the communities that they are serving. Situated qualitative interview data were co-produced with community health workers employed in a superdiverse, deprived, post-industrial region of the United Kingdom, using photo-voice methods, to develop an account of how they made sense of the challenges of their work. The analysis draws on and develops theories of risk work and resilience work, which draw on practice theory. The key findings were that, first, being a critical insider enabled community health workers to make sense of the diverse constraints on health and lifestyles within their community. Second, they understood their own public health role as limited by operating within this context, so they articulated their occupational identity as focused on supporting clients to make small but sustainable changes to their own and their families’ lifestyles. Third, the uncertainties of translating population based risk information to individual clients were (at least partially) resolved at an embodied level, with the community health workers identifying as accessible and trusted role models for the value of changed lifestyles. The article is important for policy and practice as it provides a critique of a rapidly evolving new mode of delivery of public health services, and insights on the development of this new public health workforce.

The HealtheSteps™ lifestyle prescription program to improve physical activity and modifiable risk factors for chronic disease: a pragmatic randomized controlled trial. BMC Public Health 2019; 19:841. [PMID: 31253112 PMCID: PMC6599363 DOI: 10.1186/s12889-019-7141-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2019] [Accepted: 06/10/2019] [Indexed: 01/27/2023] Open
Abstract
BACKGROUND Our objective was to determine the influence of the HealtheSteps™ lifestyle prescription program on physical activity and modifiable risk factors for chronic disease in individuals at risk. METHODS One hundred eighteen participants were recruited from 5 sites in Southwestern Ontario, Canada and randomized to either the intervention (HealtheSteps™ program, n = 59) or a wait-list control group (n = 59). The study comprised three phases: an Active Phase (0 to 6 months) consisted of bi-monthly in-person lifestyle coaching with access to a suite of eHealth technology supports (Heathesteps app, telephone coaching and a private HealtheSteps™ social network) followed by a Minimally-Supported Phase I (6 to 12 months), in which in-person coaching was removed, but participants still had access to the full suite of eHealth technology supports. In the final stage, Minimally-Supported Phase II (12 to 18 months), access to the eHealth technology supports was restricted to the HealtheSteps™ app. Assessments were conducted at baseline, 6, 12 and 18 months. The study primary outcome was the 6-month change in average number of steps per day. Secondary outcomes included: self-reported physical activity and sedentary time; self-reported eating habits; weight and body composition measures; blood pressure and health-related quality of life. Data from all participants were analyzed using an intent-to-treat approach. We applied mixed effects models for repeated measurements and adjusted for age, sex, and site in the statistical analyses. RESULTS Participants in HealtheSteps™ increased step counts (between-group [95% confidence interval]: 3132 [1969 to 4294], p < 0.001), decreased their sitting time (- 0.08 [- 0.16 to - 0.006], p = 0.03), and improved their overall healthful eating (- 1.5 [- 2.42 to - 0.58], p = 0.002) to a greater extent compared to control at 6 months. Furthermore, exploratory results showed that these individuals maintained these outcomes 12 months later, after a minimally-supported phase; and retained improvements in sedentary time and improved healthful eating after 18 months. No differences in self-reported physical activity, health-related quality of life, weight, waist circumference or blood pressure were observed between groups at 6 months. CONCLUSIONS Our findings suggest that HealtheSteps™ is effective at increasing physical activity (i.e., step counts per day), decreasing weekday sitting time, and improving healthful eating in adults at increased risk for chronic disease after 6 months; however, we did not see change in other risk factors. Nonetheless, the maintenance of these behaviours with minimal support after 12 and even 18 months indicates the promise of HealtheSteps™ for long-term sustainability. TRIAL REGISTRATION The trial was registered on April 6, 2015 with ClinicalTrials.gov (identifier: NCT02413385 ).

Abstract
Aims: Chronic knee, hip and back pain is extremely prevalent. Management guidelines emphasise maintaining physical activity and healthy weight to reduce pain and improve physical and mental wellbeing. Unfortunately, few people receive support to make lifestyle changes. We evaluated whether a health trainer—led ‘joint pain advice’ (JPA) service delivering person-centred lifestyle coaching was feasible, acceptable and effective for people with knee, hip and back pain. Methods: Feasibility of delivering a JPA service was assessed by documenting whether the health trainers could deliver JPA and its uptake. Nine health trainers delivered JPA. Participants were offered up to four appointments. At each appointment, health trainers gave people information about their condition, co-developed care plans, suggested self-management strategies and used behavioural change techniques (motivational interviewing, goal-setting and action planning) to increase physical activity and reduce body weight. Pain, function, physical activity and body mass index (BMI) were collected at baseline, 3 weeks, 6 weeks and 6 months. Focus groups captured people’s opinions of the service’s effectiveness, acceptability and usefulness. Results: Of the 105 people who enquired about JPA, 85 (81%) used the service, after which their physical activity and function improved, and pain, use of analgesia and BMI decreased. They felt more knowledgeable and better motivated to adopt and maintain healthier behaviours. They attributed these improvements to the JPA service, because of its better consultations and collaborative holistic approach. Only a minority attended all four appointments because they felt they received sufficient advice from the initial appointments. The health trainers gained knowledge and skills to support clients with musculoskeletal conditions. Conclusions: Using a holistic, patient-centred approach, health trainers can deliver lifestyle advice to people with chronic knee, hip or back pain safely, effectively and efficiently. The service was popular with recipients and health trainers, and helped people adopt healthier lifestyles that lead to reduced pain and other clinical improvements.

A conceptual framework for understanding the mechanism of action of community health workers services: the centrality of social support. J Public Health (Oxf) 2019; 41:138-148.

Abstract
OBJECTIVE To propose an empirically derived and theoretically-informed mechanism to explain how Community Health Workers (CHWs) bring about health gain in clients in England. METHODS We undertook in-depth interviews (n = 43) with CHWs and service staff working in four case studies selected using maximum variation sampling. Interviewees were encouraged to talk about the service, how they had become involved with the service, the CHW role and relationship with clients. FINDINGS We identified the provision of social support to be central to the mechanism of CHW-mediated health gain. Appropriate social support provision comprised three inter-related elements; needs assessment, social support delivery and client engagement. This mechanism is dependent on the personal characteristics of CHWs and of the roles they are employed or volunteer to carry out. CONCLUSION A range of CHW characteristics can influence the social support process, but these are context-dependent and move beyond simple notions of CHW similarity to the client. This finding has important policy implications for the development and implementation of CHW services in high income countries with super-diverse populations.

Clustering of Health-Related Behavior Patterns and Demographics. Results From the Population-Based KORA S4/F4 Cohort Study. Front Public Health 2019; 6:387. [PMID: 30723712 PMCID: PMC6350271 DOI: 10.3389/fpubh.2018.00387] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Accepted: 12/31/2018] [Indexed: 12/21/2022] Open
Abstract
Background: Health behaviors are of great importance for public health. Previous research shows that health behaviors are clustered and do not occur by chance. The main objective of this study was to investigate and describe the clustering of alcohol consumption, nutrition, physical activity and smoking while also considering the influence of sex, age and education. Methods: Using data from the population-based KORA S4/F4 cohort study, latent class regression analysis was undertaken to identify different clusters of health behavior patterns. The clusters were described according to demographics. Furthermore, the clusters were described regarding health-related quality of life at baseline and at a 7 year follow-up. Results: Based on a sample of 4,238 participants, three distinct classes were identified. One overall healthy class and two heterogeneous classes. Classes varied especially according to sex, indicating a healthier behavior pattern for females. No clear association between healthier classes and age, education or physical and mental health-related quality of life was found. Discussion: This study strengthens the literature on the clustering of health behaviors and additionally describes the identified clusters in association with health-related quality of life. More research on associations between clustering of health behaviors and important clinical outcomes is needed.

Identifying acceptable components for home-based health promotion services for older people with mild frailty: A qualitative study. HEALTH & SOCIAL CARE IN THE COMMUNITY 2018; 26:393-403. [PMID: 29210136 DOI: 10.1111/hsc.12526] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 11/06/2017] [Indexed: 06/07/2023]
Abstract
Mild frailty is common in later life, increasing the risk of hospitalisation, loss of independence and premature death. Targeted health promotion services may reduce adverse outcomes and increase quality of life; however, effective, well-developed theory-based interventions are lacking. We aimed to explore perceptions of health promotion behaviours undertaken by older people with mild frailty, barriers and facilitators to engagement, and identify potential components for new home-based health promotion services. We carried out 17 semi-structured qualitative interviews and six focus groups with 53 stakeholders, including 14 mildly frail older people, 12 family carers, 19 community health and social care professionals, and 8 homecare workers, in one urban and one semi-rural area of England. Transcripts were thematically analysed. Older people with mild frailty reported engaging in a variety of lifestyle behaviours to promote health and well-being. Key barriers or facilitators to engaging in these included transport, knowledge of local services, social support and acceptance of personal limitations. Older people, carers and professionals agreed that any new service should address social networks and mobility and tailor other content to each individual. Services should aim to increase motivation through focussing on independence and facilitate older people to continue carrying out behaviours that improve their well-being, as well as provide information, motivation, psychological support and practical support. Stakeholders agreed services should be delivered over a sustained period by trained non-specialist workers. New services including these components are likely to be acceptable to older people with mild frailty.

Is there a role for patients and their relatives in escalating clinical deterioration in hospital? A systematic review. Health Expect 2017; 20:818-825. [PMID: 27785868 PMCID: PMC5600219 DOI: 10.1111/hex.12496] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/10/2016] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Measures exist to improve early recognition of, and response to, deteriorating patients in hospital. However, deteriorating patients continue to go unrecognized. To address this, interventions have been developed that invite patients and relatives to escalate patient deterioration to a rapid response team (RRT). OBJECTIVE To systematically review articles that describe these interventions and investigate their effectiveness at reducing preventable deterioration. SEARCH STRATEGY Following PRISMA guidelines, four electronic databases and two web search engines were searched to identify literature investigating patient and relative led escalation. INCLUSION CRITERIA Articles investigating the implementation or use of systems involving patients and relatives in the detection of clinical patient deterioration and escalation of patient care to address any clinical or non-clinical outcomes were included. Articles' eligibility was validated by a second reviewer (20%). DATA EXTRACTION Data were extracted according to pre-defined criteria. DATA SYNTHESIS Narrative synthesis was applied to included studies. MAIN RESULTS Nine empirical studies and 36 grey literature articles were included in the review. Limited studies were conducted to establish the clinical effectiveness of patient and relative led escalation. Instead, studies investigated the impact of this intervention on health-care staff and available resources. Although appropriate, this reflects the infancy of research in this area. Patients and relatives did not overwhelm resources by activating the RRT. However, they did activate it to address concerns unrelated to patient deterioration. CONCLUSIONS Activating a RRT may not be the most appropriate or cost-effective method of resolving non-life-threatening concerns.

Abstract
The use of lay health advisers has become an established approach within public health, in particular for impact on health inequalities and engaging socially excluded groups. Evidence on how differences in terms of the multiple role dimensions impact the outcomes of programs is limited. This creates ambiguity for decision makers on which roles should be implemented in different contexts for different needs. This paper applies realist logic to an inquiry to explore the mechanisms that may operate in lay-led intervention models and understand how, why, and in what respect these lead to particular outcomes. It draws on a project focusing on health-related lifestyle advisers and further insights gained from a subsequent related project about outreach with traveler communities. Analysis highlights multiple and potentially interacting aspects of lay health-adviser roles that may influence their success, including characteristics of lay health advisers, characteristics of target populations, purpose or intent of interventions, and how advice is given. A model is proposed from which to examine the contexts and mechanisms of lay health advisers that may impact outcomes, and is subsequently applied to two examples of reported lay health-adviser interventions. The combination of skills and characteristics of lay health advisers must be considered when planning which interventions might be appropriate when targeting specific needs or target populations. Focus only on the peer/layperson distinction may overlook other potentially important skills and mechanisms of action integral to lay health-adviser roles.

Implementation of eMental Health care: viewpoints from key informants from organizations and agencies with eHealth mandates. BMC Med Inform Decis Mak 2017; 17:78. [PMID: 28577543 PMCID: PMC5455087 DOI: 10.1186/s12911-017-0474-9] [Citation(s) in RCA: 39] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2016] [Accepted: 05/24/2017] [Indexed: 12/25/2022] Open
Abstract
Background The use of technology such as computers, tablets, and smartphones to improve access to and the delivery of mental health care (eMental Health care) is growing worldwide. However, despite the rapidly expanding evidence base demonstrating the efficacy of eMental Health care, its implementation in clinical practice and health care systems remains fragmented. To date, no peer-reviewed, key-informant studies have reported on the perspectives of decision-makers concerned with whether and how to implement eMental Health care. Methods From September to November 2015, we conducted 31 interviews with key informants responsible for leadership, policy, research, and/ or information technology in organizations influential in the adoption of technology for eMental Health care. Deductive and inductive thematic analyses of transcripts were conducted using the Behavior Change Wheel as an organizing framework. Frequency and intensity effect sizes were calculated for emerging themes to further explore patterns within the data. Results Key informant responses (n = 31) representing 6 developed countries and multiple organizations showed consensus on common factors impacting implementation: individual and organizational capacities (e.g., computer literacy skills [patients and providers], knowledge gaps about cyber security, limited knowledge of available services); motivational drivers of technology-based care (e.g., extending care, data analytics); and opportunities for health systems to advance eMental Health care implementation (e.g., intersectoral research, rapid testing cycles, sustainable funding). Frequency effect sizes showed strong associations between implementation and credibility, knowledge, workflow, patient empowerment, electronic medical record (EMR) integration, sustained funding and intersectoral networks. Intensity effect sizes showed the highest concentration of statements (>10% of all comments) related to funding, credibility, knowledge gaps, and patient empowerment. Conclusion This study provides previously unavailable information about key informant perspectives on eMental Health care implementation. The themes that emerged, namely the need to intensify intersectoral research, measure/monitor readiness to implement, define cost-utility benchmarks, raise awareness about available technologies, and test assumptions that ‘proven’ technologies will be easily integrated can inform the design and evaluation of eMental Health care implementation models.

Abstract
BACKGROUND Physical inactivity is one of the leading causes of chronic disease in Canadian adults. With less than 50% of Canadian adults reaching the recommended amount of daily physical activity, there is an urgent need for effective programs targeting this risk factor. HealtheSteps™ is a healthy lifestyle prescription program, developed from an extensive research base to address risk factors for chronic disease such as physical inactivity, sedentary behaviour and poor eating habits. HealtheSteps™ participants are provided with in-person lifestyle coaching and access to eHealth technologies delivered in community-based primary care clinics and health care organizations. METHOD/DESIGN To determine the effectiveness of Healthesteps™, we will conduct a 6-month pragmatic randomized controlled trial with integrated process and economic evaluations of HealtheSteps™ in 5 clinic settings in Southwestern Ontario. 110 participants will be individually randomized (1:1; stratified by site) to either the intervention (HealtheSteps™ program) or comparator (Wait-list control). There are 3 phases of the HealtheSteps™ program, lasting 6 months each. The active phase consists of bi-monthly in-person coaching with access to a full suite of eHealth technology supports. During the maintenance phase I, the in-person coaching will be removed, but participants will still have access to the full suite of eHealth technology supports. In the final stage, maintenance phase II, access to the full suite of eHealth technology supports is removed and participants only have access to publicly available resources and tools. DISCUSSION This trial aims to determine the effectiveness of the program in increasing physical activity levels and improving other health behaviours and indicators, the acceptability of the HealtheSteps™ program, and the direct cost for each person participating in the program as well as the costs associated with delivering the program at the different community sites. These results will inform future optimization and scaling up of the program into additional community-based primary care sites. TRIAL REGISTRATION NCT02413385 (Clinicaltrials.gov).

How lay health workers tailor in effective health behaviour change interventions: a protocol for a systematic review. Syst Rev 2016; 5:102.

Abstract
BACKGROUND Lay health workers (LHWs) are utilised as a channel of delivery in many health interventions. While they have no formal professional training related to their role, they utilise their connections with the target group or community in order to reach individuals who would not normally readily engage with health services. Lay health worker programmes are often based on psychological theories of behaviour change that point to 'tailoring to individuals' needs or characteristics' as key to success. Although lay health workers have been shown to be effective in many contexts, there is, as yet, little clarity when it comes to how LHWs assess individuals' needs in order to tailor their interventions. This study aims to develop a better understanding of the effective implementation of tailoring in lay health worker interventions by appraising evidence and synthesising studies that report evaluations of tailored interventions. METHOD Health and psychology electronic databases (EMBASE, CINAHL, MEDLINE and PsycINFO) will be searched. Reference lists of included studies will also be searched. For articles that are deemed to be potentially relevant, we will employ a 'cluster searching' technique in order to identify all published papers related to a relevant intervention. Cluster searching will be undertaken in an effort to maximise the breadth and depth of description of the intervention. Quantitative studies will be assessed using the Quality Assessment Tool for Quantitative Studies, developed by the Effective Public Health Practice Project, ON, Canada. Qualitative studies will be assessed using the Critical Appraisal Skills Programme (CASP) checklist for qualitative research. Sythesising the data will enable the development of a taxonomy of strategies for the criteria used for individual assessment of recipients' needs and the ways in which messages or actions are tailored to these individual criteria by LHWs. DISCUSSION This systematic review focuses specifically on how health promotion and support is individually tailored in effective programmes by LHWs. This study will be of value to those involved in the design and implementation of interventions that utilise a LHW. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42015030071.

Abstract
BACKGROUND Tick transmission of Borrelia spirochetes to humans results in significant morbidity from Lyme disease worldwide. Serum concentrations of antibodies against outer surface protein A (OspA) were shown to correlate with protection from infection with Borrelia burgdorferi, the primary cause of Lyme disease in the United States. METHODS Mice transgenic for human immunoglobulin genes were immunized with OspA from B. burgdorferi to generate human monoclonal antibodies (HuMabs) against OspA. HuMabs were generated and tested in in vitro borreliacidal assays and animal protection assays. RESULTS Nearly 100 unique OspA-specific HuMabs were generated, and 4 HuMabs (221-7, 857-2, 319-44, and 212-55) were selected as lead candidates on the basis of borreliacidal activity. HuMabs 319-44, 857-2, and 212-55 were borreliacidal against 1 or 2 Borrelia genospecies, whereas 221-7 was borreliacidal (half maximal inhibitory concentration, < 1 nM) against B. burgdorferi, Borrelia afzelii, and Borrelia garinii, the 3 main genospecies endemic in the United States, Europe, and Asia. All 4 HuMabs completely protected mice from infection at 10 mg/kg in a murine model of tick-mediated transmission of B. burgdorferi CONCLUSIONS Our study indicates that OspA-specific HuMabs can prevent the transmission of Borrelia and that administration of these antibodies could be employed as preexposure prophylaxis for Lyme disease.

Abstract
The current article details a position statement and recommendations for future research and practice on planning and implementation intentions in health contexts endorsed by the Synergy Expert Group. The group comprised world-leading researchers in health and social psychology and behavioural medicine who convened to discuss priority issues in planning interventions in health contexts and develop a set of recommendations for future research and practice. The expert group adopted a nominal groups approach and voting system to elicit and structure priority issues in planning interventions and implementation intentions research. Forty-two priority issues identified in initial discussions were further condensed to 18 key issues, including definitions of planning and implementation intentions and 17 priority research areas. Each issue was subjected to voting for consensus among group members and formed the basis of the position statement and recommendations. Specifically, the expert group endorsed statements and recommendations in the following areas: generic definition of planning and specific definition of implementation intentions, recommendations for better testing of mechanisms, guidance on testing the effects of moderators of planning interventions, recommendations on the social aspects of planning interventions, identification of the preconditions that moderate effectiveness of planning interventions and recommendations for research on how people use plans.

Abstract
Type 2 diabetes mellitus is most prevalent in deprived communities and patients with low health literacy have worse glycaemic control and higher rates of diabetic complications. However, recruitment from this patient population into intervention trials is highly challenging. We conducted a study to explore the feasibility of recruitment and to assess the effect of a lay health trainer intervention, in patients with low health literacy and poorly controlled diabetes from a socioeconomically disadvantaged population, compared with usual care. Methods. A pilot RCT comparing the LHT intervention with usual care. Patients with HbA1c > 7.5 (58 mmol/mol) were recruited. Baseline and 7-month outcome data were entered directly onto a laptop to reduce patient burden. Results. 76 patients were recruited; 60.5% had low health literacy and 75% were from the most deprived areas of England. Participants in the LHT arm had significantly improved mental health (p = 0.049) and illness perception (p = 0.040). The intervention was associated with lower resource use, better patient self-care management, and better QALY profile at 7-month follow-up. Conclusion. This study describes successful recruitment strategies for hard-to-reach populations. Further research is warranted for this cost-effective, relatively low-cost intervention for a population currently suffering a disproportionate burden of diabetes, to demonstrate its sustained impact on treatment effects, health, and health inequalities.

Lifestyle Behaviours Add to the Armoury of Treatment Options for Panic Disorder: An Evidence-Based Reasoning. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:7017-43. [PMID: 26095868 PMCID: PMC4483746 DOI: 10.3390/ijerph120607017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/06/2015] [Revised: 06/11/2015] [Accepted: 06/12/2015] [Indexed: 11/16/2022]
Abstract
This article presents an evidence-based reasoning, focusing on evidence of an Occupational Therapy input to lifestyle behaviour influences on panic disorder that also provides potentially broader application across other mental health problems (MHP). The article begins from the premise that we are all different. It then follows through a sequence of questions, examining incrementally how MHPs are experienced and classified. It analyses the impact of individual sensitivity at different levels of analysis, from genetic and epigenetic individuality, through neurotransmitter and body system sensitivity. Examples are given demonstrating the evidence base behind the logical sequence of investigation. The paper considers the evidence of how everyday routine lifestyle behaviour impacts on occupational function at all levels, and how these behaviours link to individual sensitivity to influence the level of exposure required to elicit symptomatic responses. Occupational Therapists can help patients by adequately assessing individual sensitivity, and through promoting understanding and a sense of control over their own symptoms. It concludes that present clinical guidelines should be expanded to incorporate knowledge of individual sensitivities to environmental exposures and lifestyle behaviours at an early stage.

Web searching for systematic reviews: a case study of reporting standards in the UK Health Technology Assessment programme. BMC Res Notes 2015; 8:153. [PMID: 25889619 PMCID: PMC4406036 DOI: 10.1186/s13104-015-1079-y] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2014] [Accepted: 03/20/2015] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Identifying literature for a systematic review requires searching a variety of sources. The main sources are typically bibliographic databases. Web searching using search engines and websites may be used to identify grey literature. Searches should be reported in order to ensure transparency and reproducibility. This study assesses the reporting of web searching for systematic reviews carried out by the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) programme (UK). The study also makes recommendations about reporting web searching for systematic reviews in order to achieve a reasonable level of transparency and reproducibility. METHODS Systematic reviews were identified by searching the HTA database via the Centre for Reviews and Dissemination (CRD) website. Systematic reviews were included in the study if they made reference to searching the web using either search engines or websites. A data-extraction checklist was designed to record how web searching was reported. The checklist recorded whether a systematic review reported: the names of search engines or websites; the dates they were searched; the search terms; the results of the searches; and, in the case of websites, whether a URL was reported. RESULTS 554 HTA reports published between January 2004 and December 2013 were identified. 300 of these reports are systematic reviews, of which 108 report web searching using either a search engine or a website. Overall, the systematic reviews assessed in the study exhibit a low standard of web search reporting. In the majority of cases, the only details reported are the names of websites (n = 54) or search engines (n = 33). A small minority (n = 6) exhibit the highest standard of web search reporting. CONCLUSIONS Most web search reporting in systematic reviews carried out on the UK HTA programme is not detailed enough to ensure transparency and reproducibility. Transparency of reporting could be improved by adhering to a reporting standard such as the standard detailed in the CRD systematic reviews methods guidance. Reproducibility is harder to achieve due to the frequency of changes to websites and search engines.

Comparing the effectiveness of an enhanced MOtiVational intErviewing InTervention (MOVE IT) with usual care for reducing cardiovascular risk in high risk subjects: study protocol for a randomised controlled trial. Trials 2015; 16:112. [PMID: 25886569 PMCID: PMC4399238 DOI: 10.1186/s13063-015-0593-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Accepted: 02/06/2015] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Interventions targeting multiple risk factors for cardiovascular disease (CVD), including poor diet and physical inactivity, are more effective than interventions targeting a single risk factor. A motivational interviewing (MI) intervention can provide modest dietary improvements and physical activity increases, while adding cognitive behaviour therapy (CBT) skills may enhance the effects of MI. We designed a randomised controlled trial (RCT) to examine whether specific behaviour change techniques integrating MI and CBT result in favourable changes in weight and physical activity in those at high risk of CVD. A group and individual intervention will be compared to usual care. A group intervention offers potential benefits from social support and may be more cost effective. METHODS/DESIGN Individuals aged between 40 and 74 years in 11 South London Clinical Commissioning Groups who are at high risk of developing CVD (≥20%) in the next 10 years will be recruited. A sample of 1,704 participants will be randomised to receive the enhanced MI intervention, delivered by trained healthy lifestyle facilitators (HLFs), in group or individual formats, in 10 sessions (plus an introductory session) over one year, or usual care. Randomisation will be conducted by King's College London Clinical Trials Unit and researchers collecting outcome data will be blinded to treatment allocation. At 12-month and 24-month follow-up assessments, primary outcomes will be change in weight and physical activity (average steps per day). Secondary outcomes include changes in low-density lipoprotein cholesterol and CVD risk score. Incidence of CVD events since baseline will be recorded. A process evaluation will be conducted to evaluate factors which impact on delivery, adherence and outcome. An economic evaluation will estimate relative cost-effectiveness of each type of intervention delivery. DISCUSSION This RCT assesses the effectiveness of a healthy lifestyle intervention for people at high risk of CVD. Benefits of the study include the ethnic and socioeconomic diversity of the study population and that, via social support within the group setting and long-term follow-up period, the intervention offers the potential to support maintenance of a healthy lifestyle. TRIAL REGISTRATION This trial is registered with the ISRCTN registry (identifier: ISRCTN84864870, registered 15 May 2012).

The challenge of implementing peer-led interventions in a professionalized health service: a case study of the national health trainers service in England. Milbank Q 2015; 92:725-53.

Abstract
UNLABELLED Policy Points: In 2004, England's National Health Service introduced health trainer services to help individuals adopt healthier lifestyles and to redress national health inequalities. Over time these anticipated community-focused services became more NHS-focused, delivering "downstream" lifestyle interventions. At the same time, individuals' lifestyle choices were abstracted from the wider social determinants of health and the potential to address inequalities was diminished. While different service models are needed to engage hard-to-reach populations, the long-term sustainability of any new service model depends on its aligning with the established medical system's characteristics. CONTEXT In 2004, the English Public Health White Paper Choosing Health introduced "health trainers" as new members of the National Health Service (NHS) workforce. Health trainers would offer one-to-one peer-support to anyone who wished to adopt and maintain a healthier lifestyle. Choosing Health implicitly envisaged health trainers working in community settings in order to engage "hard-to-reach" individuals and other groups who often have the poorest health but who engage the least with traditional health promotion and other NHS services. METHODS During longitudinal case studies of 6 local health trainer services, we conducted in-depth interviews with key stakeholders and analyzed service activity data. FINDINGS Rather than an unproblematic and stable implementation of community-focused services according to the vision in Choosing Health, we observed substantial shifts in the case studies' configuration and delivery as the services embedded themselves in the local NHS systems. To explain these observations, we drew on a recently proposed conceptual framework to examine and understand the adoption and diffusion of innovations in health care systems. CONCLUSIONS The health trainer services have become more "medicalized" over time, and in doing so, the original theory underpinning the program has been threatened. The paradox is that policymakers and practitioners recognize the need to have a different service model for traditional NHS services if they want hard-to-reach populations to engage in preventive actions as a first step to redress health inequalities. The long-term sustainability of any new service model, however, depends on its aligning with the established medical system's (ie, the NHS's) characteristics.

Longitudinal associations of health-related behavior patterns in adolescence with change of weight status and self-rated health over a period of 6 years: results of the MoMo longitudinal study. BMC Pediatr 2014; 14:242. [PMID: 25270112 PMCID: PMC4190442 DOI: 10.1186/1471-2431-14-242] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2014] [Accepted: 09/24/2014] [Indexed: 12/03/2022] Open
Abstract
Background Promoting a healthy lifestyle especially in adolescents is important because health-related behaviors adopted during adolescence most often track into adulthood. Longitudinal studies are necessary for identifying health-related risk groups of adolescents and defining target groups for health-promoting interventions. Multiple health behavior research may represent a useful approach towards a better understanding of the complexity of health-related behavior. The aim of this study was to examine the longitudinal association of health-related behavior patterns with change of weight status and self-rated health in adolescents in Germany. Methods Within the framework of the longitudinal German Health Interview and Examination Survey for Children and Adolescents (KiGGS) and the Motorik-Modul (MoMo), four clusters of typical health-related behavior patterns of adolescents have been previously identified. Therefor the variables ‘physical activity’, ‘media use’ and ‘healthy nutrition’ were included. In the current study longitudinal change of objectively measured weight status (N = 556) and self-rated health (N = 953) in the four clusters was examined. Statistical analyses comprised T-tests for paired samples, McNemar tests, multinomial logistic regression analysis and two-way ANOVA with repeated measures. Results The prevalence of overweight increased in all four clusters. The health-related behavior pattern of low activity level with high media use and low diet quality had the strongest increase in prevalence of overweight, while the smallest and non-significant increase was found with the behavior pattern of a high physical activity level and average media use and diet quality. Only some significant relationships between health-related behaviour patterns and change in self-rated health were observed. Conclusions High-risk patterns of health-related behavior were identified. Further, cumulative as well as compensatory effects of different health-related behaviors on each other were found. The information gained in this study contributes to a better understanding of the complexity of health-related behavior and its impact on health parameters and may facilitate the development of targeted prevention programs.

Abstract
BackgroundThere is growing interest in theory-driven, qualitative and mixed-method approaches to systematic review, such as realist and meta-narrative review. These approaches offer the potential to expand the knowledge base in policy-relevant areas. However, the quality of such reviews can be difficult to assess.ObjectivesThe aim of this project was to produce methodological guidance, publication standards and training resources for those seeking to undertake realist and/or meta-narrative reviews.Methods/designWe (1) collated and summarised existing literature on the principles of good practice in realist and meta-narrative systematic reviews; (2) considered the extent to which these principles had been followed by published and in-progress reviews, thereby identifying how rigour may have been lost and how existing methods could be improved; (3) used an online Delphi method with an interdisciplinary panel of experts from academia and policy, to produce a draft set of methodological steps and publication standards; (4) produced training materials with learning objectives linked to these steps; (5) refined these standards and training materials prospectively on real reviews in progress, capturing methodological and other challenges as they arose; (6) synthesised expert input, evidence review and real-time problem analysis into more definitive guidance and standards; and (7) disseminated outputs to audiences in academia and policy.ResultsAn important element of this study was the establishment of an e-mail mailing list to bring together researches in the field (www.jiscmail.ac.uk/RAMESES). Our literature review identified 35 and nine realist and meta-narrative reviews respectively. Analysis and discussion within the project team produced a summary of the published literature, and common questions and challenges into briefing materials for the Delphi panel, comprising 37 and 33 members (for realist and meta-narrative reviews respectively). Within three rounds this panel had reached a consensus on 19 (realist) and 20 (meta-narrative) key publication standards, with an overall response rate of 90% and 91% respectively. The Realist And Meta-narrative Evidence Syntheses – Evolving Standards (RAMESES) publication standards for realist syntheses and meta-narrative reviews were published in open-access journals and quickly became highly accessed. The RAMESES quality standards and training materials drew together the following sources of data: (1) personal expertise as researchers and trainers; (2) data from the Delphi panels; (3) feedback from participants at training sessions we ran; and (4) comments made on RAMESES mailing list. The quality standards and training materials are freely available online (www.ramesesproject.org).DiscussionThe production of these standards and guidance drew on multiple sources of knowledge and expertise, and a high degree of a consensus was achieved despite ongoing debate among researchers about the overall place of these methodologies in the secondary research toolkit. As with all secondary research methods, guidance on quality assurance and uniform reporting is an important step towards improving quality and consistency of studies. We anticipate that as more reviews are undertaken, further refinement will be needed to the publication and quality standards and training materials.LimitationsThe project’s outputs are not definitive and in the future updating and further development is likely to be needed.ConclusionAn initial set of publication standards, quality standards and training materials have been produced for researchers, users and funders of realist or meta-narrative reviews. As realist and meta-narrative reviews are relatively new approaches to evidence synthesis, methodological development is needed for both review approaches.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract
BACKGROUND The NHS Health Check Programme was launched in England in 2009, offering a vascular risk assessment to people aged 40-74 years without established disease. Socio-economic deprivation is associated with higher risk of cardiovascular disease and lower uptake of screening. We evaluated the potential impact of a community-based health check service that sought to address health inequalities through the involvement of lay health trainers. METHODS Key stakeholder discussions (n = 20), secondary analysis of client monitoring data (n = 774) and patient experience questionnaires (n = 181). RESULTS The health check programme was perceived as an effective way of engaging people in conversations about their health. More than half (57.6%) of clients were aged under 50 years and a similar proportion (60.5%) were from socio-economically deprived areas. Only 32.7% from the least affluent areas completed a full health check in comparison with 44.4% from more affluent areas. Eligible men were more likely than eligible women to complete a health check (59.4 versus 33.8%). CONCLUSIONS A community-based, health trainer-led approach may add value by offering an acceptable alternative to health checks delivered in primary care settings. The service appeared to be particularly successful in engaging men and younger age groups. However, there exists the potential for intervention-generated inequalities.

Modes of delivery in preventive intervention studies: a rapid review. Eur J Clin Invest 2014; 44:688-96.

Abstract
BACKGROUND This review was commissioned to generate broad discussion about how to select intervention delivery modes when designing a complex, preventive intervention aimed at chronic disease through the promotion of physical activity, healthy diet and/or medication adherence. In this context, we asked, what are the delivery modes? What are the important design considerations? And how do these compare (e.g. strengths, limitations)? MATERIALS AND METHODS This review utilized the methods of rapid review, an emerging methodology arising from health technology assessment. The search strategy was applied in Embase and MEDLINE. A qualitative, narrative synthesis was performed on included articles. RESULTS After screening, 21 articles remained for synthesis (10 systematic reviews, including 1 review of reviews; four trials or studies; three commentaries or conference proceedings; and 2 were scoping projects). Our synthesis determined that major categories of design considerations when selecting intervention delivery modes include attention to the (i) candidate mode types, (ii) settings and social environment, (iii) intensity and timing, (iv) provider, (v) study population and participants, (vi) cost, (vii) behaviour change technique and (viii) theoretical basis. CONCLUSION An array of modes of delivery is available for each of the intervention strategies under consideration (i.e. physical activity, dietary change and medication adherence). No single delivery mode was clearly more appropriate or more effective than another, each having unique strengths and limitations. Delivery mode decisions that take the above-mentioned factors (i-viii) into account will be more fit-for-purpose than those that do not.

Making and maintaining lifestyle changes with the support of a lay health advisor: longitudinal qualitative study of health trainer services in northern England. PLoS One 2014; 9:e94749.

Abstract
Objective To explore and document the experiences of those receiving support from a lay health trainer, in order to inform the optimisation and evaluation of such interventions. Design Longitudinal qualitative study with up to four serial interviews conducted over 12 months. Interviews were transcribed and analysed using the constant comparative approach associated with grounded theory. Participants 13 health trainers, 5 managers and 26 clients. Setting Three health trainer services targeting disadvantaged communities in northern England. Results The final dataset comprised 116 interviews (88 with clients and 28 with staff). Discussions with health trainers and managers revealed a high degree of heterogeneity between the local services in terms of their primary aims and activities. However, these were found to converge over time. There was agreement that health trainer interventions are generally ‘person-centred’ in terms of being tailored to the needs of individual clients. This led to a range of self-reported outcomes, including behaviour changes, physical health improvements and increased social activity. Factors impacting on the maintenance of lifestyle changes included the cost and timing of health-promoting activities, ill-health or low mood. Participants perceived a need for ongoing access to low cost facilities to ensure that any lifestyle changes can be maintained in the longer term. Conclusions Health trainers may be successful in terms of supporting people from socio-economically disadvantaged communities to make positive lifestyle changes, as well as achieving other health-related outcomes. This is not a ‘one-size-fits-all’ approach; commissioners and providers should select the intervention models that best meet the needs of their local populations. By delivering holistic interventions that address multiple lifestyle risks and incorporate relapse prevention strategies, health trainers could potentially have a significant impact on health inequalities. However, rigorous, formal outcome and economic evaluation of the range of health trainer delivery models is needed.

Abstract
The Population Studies Research Network of Cancer Care Ontario hosted a strategic planning workshop to establish an agenda for a prevention intervention research program in Ontario, including priority topics for investigation and design considerations. The two-day workshop included: presentations on background papers developed to facilitate participants' preparation for and discussions in the workshop; keynote presentations on intervention research concerning primary prevention of chronic diseases, design and study implementation considerations; a dedicated session on critical and creative thinking to stimulate participation and discussion topics; break out groups to identify, discuss and present study ideas, designs, implementation considerations; and a consensus process to discuss and identify recommendations for research priorities and next steps. The retreat yielded the following recommendations: 1) develop an intervention research agenda that includes working with existing large-scale cohorts; 2) develop an intervention research agenda that includes novel research designs that could target individuals or groups; and 3) develop an intervention research agenda in which studies collect data on costs, define stakeholders, and ensure clear strategies for stakeholder engagement and knowledge transfer. The Population Studies Research Network will develop options from these recommendations and release a call for proposals in 2014 for intervention research pilot projects that reflect these recommendations. Pilot projects will be evaluated based on their fit with the retreat's recommendations, and their potential to scale up to full studies and application in practice.

Cervical cancer screening: a prospective cohort study of the effects of historical patient compliance and a population-based informatics prompted reminder on screening rates. J Eval Clin Pract 2014; 20:136-43.

Abstract
AIMS AND OBJECTIVES The aim of this study was to assess the impact of historical screening compliance with the effectiveness of patient reminder letters on cervical cancer screening rates. METHOD Using population-based informatics systems, women with no cervical cancer screening in the prior 3 years were identified in two primary care clinics, Mayo Family Clinic Northeast (NE; n = 1613) and Northwest (NW; n = 1088). Patients were divided into two compliance groups: overdue/unknown screening status at study start or previously compliant. The NE Clinic sent reminder letters over a 6 months window to patients eligible for screening at the study start or during the study that were also identified as employees/dependents (E/D). There were 795 intervention (NE Clinic E/D patients) and 1906 control subjects. Using an intent-to-treat analysis, differences in screening rates were assessed. RESULTS A higher unadjusted screening rate was observed for the E/D group than the non-E/D group at both sites (32.7 versus 18.2% at NW, P < 0.001; 39.0 versus 14.7% at NE, P < 0.001). For the historically compliant group, unadjusted screening rates were higher for those who received letters (E/D subjects at NE) versus those who did not (E/D subjects at NW; 56.1 versus 44.5%, P = 0.01). No difference was observed between E/D subjects at NE (received letters) and NW (no letters) for the overdue/unknown group (27.4 versus 25.9%, P = 0.62). There was no difference in screening rates for non-E/D subjects at NE versus at NW (none of whom received letters) for both the compliant (24.2 versus 30.6%, P = 0.18) and the overdue/unknown groups (11.9 versus 13.0%, P = 0.59). Multivariate logistic regression models showed a significant overall effect of E/D status (P = 0.006), compliance group (P < 0.001), and the interaction between clinic site and E/D status (P = 0.04). CONCLUSION Among insured women, reminder letters appear to improve cervical cancer screening rates for those with a history of screening compliance. Reminder letters appear insufficient to motivate women if screening is overdue. Further investigation of the cohort of women overdue for screening is needed to develop interventions to successfully target this group.

Abstract
Clinical trials have demonstrated that it is possible to prevent diabetes through lifestyle modification, pharmacological intervention, and surgery. This review aims to summarize the effectiveness of these various therapeutic interventions in reducing the risk of progression of prediabetes to diabetes, and address the challenges to implement a diabetes prevention program at a community level. Strategies focusing on intensive lifestyle changes are not only efficient but cost-effective and/or cost-saving. Indeed, lifestyle intervention in people at high risk for type 2 diabetes mellitus (T2DM) has been successful in achieving sustained behavioral changes and a reduction in diabetes incidence even after the counseling is stopped. Although prediabetes is associated with health and economic burdens, it has not been adequately addressed by interventions or regulatory agencies in terms of prevention or disease management. Lifestyle intervention strategies to prevent T2DM should be distinct for different populations around the globe and should emphasize sex, age, ethnicity, and cultural and geographical considerations to be feasible and to promote better compliance. The translation of diabetes prevention research at a population level, especially finding the most effective methods of preventing T2DM in various societies and cultural settings remains challenging, but must be accomplished to stop this worldwide epidemic.

Abstract
BACKGROUND Development of new peer or lay health-related lifestyle advisor (HRLA) roles is one response to the need to enhance public engagement in, and improve cost-effectiveness of, health improvement interventions. This article synthesises evidence on the cost-effectiveness of HRLA interventions aimed at adults in developed countries, derived from the first systematic review of the effectiveness, cost-effectiveness, equity and acceptability of different types of HRLA role. METHODS The best available evidence on the cost-effectiveness of HRLA interventions was obtained using systematic searches of 20 electronic databases and key journals, as well as searches of the grey literature and the internet. Interventions were classified according to the primary health behaviour targeted and intervention costs were estimated where necessary. Lifetime health gains were estimated (in quality-adjusted life years, where possible), based on evidence of effectiveness of HRLAs in combination with published estimates of the lifetime health gains resulting from lifestyle changes, and assumptions over relapse. Incremental cost-effectiveness ratios are reported. RESULTS Evidence of the cost-effectiveness of HRLAs was identified from 24 trials included in the systematic review. The interventions were grouped into eight areas. We found little evidence of effectiveness of HRLAs for promotion of exercise/improved diets. Where HRLAs were effective cost-effectiveness varied considerably: Incremental Cost effectiveness Ratios were estimated at £6,000 for smoking cessation; £14,000 for a telephone based type 2 diabetes management; and £250,000 or greater for promotion of mammography attendance and for HIV prevention amongst drug users. We lacked sufficient evidence to estimate ICERs for breastfeeding promotion and mental health promotion, or to assess the impact of HRLAs on health inequalities. CONCLUSIONS Overall, there is limited evidence suggesting that HRLAs are cost-effective in terms of changing health-related knowledge, behaviours or health outcomes. The evidence that does exist indicates that HRLAs are only cost-effective when they target behaviours likely to have a large impact on overall health-related quality of life. Further development of HRLA interventions needs to target specific population health needs where potential exists for significant improvement, and include rigorous evaluation to ensure that HRLAs provide sufficient value for money.

Abstract
This article provides an overview of mixed methods research and mixed studies reviews. These two approaches are used to combine the strengths of quantitative and qualitative methods and to compensate for their respective limitations. This article is structured in three main parts. First, the epistemological background for mixed methods will be presented. Afterward, we present the main types of mixed methods research designs and techniques as well as guidance for planning, conducting, and appraising mixed methods research. In the last part, we describe the main types of mixed studies reviews and provide a tool kit and examples. Future research needs to offer guidance for assessing mixed methods research and reporting mixed studies reviews, among other challenges.

Abstract
AIMS To explore 12-month changes in cardiovascular disease (CVD) risk and health-related quality of life (HRQoL) in participants of a health trainer (HT) programme. METHODS Participants were 994 adults with at least one established CVD risk factor who were referred to a HT programme. The primary outcome was 12-month change in Framingham 10 year CVD risk score. Secondary outcomes included change in individual risk factors and HRQoL. Intention to treat analysis was used to explore 12-month changes for the overall population and those classified 'high risk' (≥20% CVD risk) at baseline. RESULTS At baseline, 33.6% of participants were classified as 'high CVD risk' and 95.7% were overweight or obese. There were modest 12-month improvements in most modifiable CVD risk factors, but not overall CVD risk (-0.25±6.50%). In 'high-risk' participants significant reductions were evident for overall CVD risk (-2.34±8.13%) and individual risk factors. Small, significant 12-month HRQoL improvements were observed, but these were not associated with CVD risk change. CONCLUSIONS Significant CVD risk reductions in participants in this HT programme with high baseline CVD risk (.20%) in HRQoL in the population as a whole indicated that the programme in its current form should target high-risk patients.

A cluster-analytic approach towards multidimensional health-related behaviors in adolescents: the MoMo-Study. BMC Public Health 2012; 12:1128. [PMID: 23273134 PMCID: PMC3552670 DOI: 10.1186/1471-2458-12-1128] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2012] [Accepted: 12/26/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Although knowledge on single health-related behaviors and their association with health parameters is available, research on multiple health-related behaviors is needed to understand the interactions among these behaviors. The aims of the study were (a) to identify typical health-related behavior patterns in German adolescents focusing on physical activity, media use and dietary behavior; (b) to describe the socio-demographic correlates of the identified clusters and (c) to study their association with overweight. METHODS Within the framework of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) and the "Motorik-Modul" (MoMo), 1,643 German adolescents (11-17 years) completed a questionnaire assessing the amount and type of weekly physical activity in sports clubs and during leisure time, weekly use of television, computer and console games and the frequency and amount of food consumption. From this data the three indices 'physical activity', 'media use' and 'healthy nutrition' were derived and included in a cluster analysis conducted with Ward's Method and K-means analysis. Chi-square tests were performed to identify socio-demographic correlates of the clusters as well as their association with overweight. RESULTS Four stable clusters representing typical health-related behavior patterns were identified: Cluster 1 (16.2%)--high scores in physical activity index and average scores in media use index and healthy nutrition index; cluster 2 (34.6%)--high healthy nutrition score and below average scores in the other two indices; cluster 3 (18.4%)--low physical activity score, low healthy nutrition score and very high media use score; cluster 4 (30.5%)--below average scores on all three indices. Boys were overrepresented in the clusters 1 and 3, and the relative number of adolescents with low socio-economic status as well as overweight was significantly higher than average in cluster 3. CONCLUSIONS Meaningful and stable clusters of health-related behavior were identified. These results confirm findings of another youth study hence supporting the assumption that these clusters represent typical behavior patterns of adolescents. These results are particularly relevant for the characterization of target groups for primary prevention of lifestyle diseases.

Abstract
AIM A protocol for a new peer-led self-management programme for community-dwelling older people with diabetes in Shanghai, China. BACKGROUND The increasing prevalence of type 2 diabetes poses major public health challenges. Appropriate education programmes could help people with diabetes to achieve self-management and better health outcomes. Providing education programmes to the fast growing number of people with diabetes present a real challenge to Chinese healthcare system, which is strained for personnel and funding shortages. Empirical literature and expert opinions suggest that peer education programmes are promising. DESIGN Quasi-experimental. METHODS This study is a non-equivalent control group design (protocol approved in January, 2008). A total of 190 people, with 95 participants in each group, will be recruited from two different, but similar, communities. The programme, based on Social Cognitive Theory, will consist of basic diabetes instruction and social support and self-efficacy enhancing group activities. Basic diabetes instruction sessions will be delivered by health professionals, whereas social support and self-efficacy enhancing group activities will be led by peer leaders. Outcome variables include: self-efficacy, social support, self-management behaviours, depressive status, quality of life and healthcare utilization, which will be measured at baseline, 4 and 12 weeks. DISCUSSION This theory-based programme tailored to Chinese patients has potential for improving diabetes self-management and subsequent health outcomes. In addition, the delivery mode, through involvement of peer leaders and existing community networks, is especially promising considering healthcare resource shortage in China.

Abstract
Most children, including lower socioeconomic status and ethnic minority children, play video games, use computers, and have cell phones, and growing numbers have smart phones and electronic tablets. They are comfortable with, even prefer, electronic media. Many expect to be entertained and have a low tolerance for didactic methods. Thus, health promotion with children needs to incorporate more interactive media. Interactive media for weight control and health promotion among children can be broadly classified into web-based educational/therapeutic programs, tailored motivational messaging systems, data monitoring and feedback systems, active video games, and diverse forms of interactive multimedia experiences involving games. This article describes the primary characteristics of these different technological methods; presents the strengths and weaknesses of each in meeting the needs of children of different ages; emphasizes that we are in the earliest stages of knowing how best to design these systems, including selecting the optimal requisite behavioral change theories; and identifies high-priority research issues. Gaming and technology offer many exciting, innovative opportunities for engaging children and promoting diet and physical activity changes that can contribute to obesity prevention and weight loss maintenance. Research needs to clarify optimal procedures for effectively promoting change with each change procedure.

Promoting smoking cessation in Pakistani and Bangladeshi men in the UK: pilot cluster randomised controlled trial of trained community outreach workers. Trials 2011; 12:197. [PMID: 21854596 PMCID: PMC3177779 DOI: 10.1186/1745-6215-12-197] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2011] [Accepted: 08/19/2011] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Smoking prevalence is high among Pakistani and Bangladeshi men in the UK, but there are few tailored smoking cessation programmes for Pakistani and Bangladeshi communities. The aim of this study was to pilot a cluster randomised controlled trial comparing the effectiveness of Pakistani and Bangladeshi smoking cessation outreach workers with standard care to improve access to and the success of English smoking cessation services. METHODS A pilot cluster randomised controlled trial was conducted in Birmingham, UK. Geographical lower layer super output areas were used to identify natural communities where more than 10% of the population were of Pakistani and Bangladeshi origin. 16 agglomerations of super output areas were randomised to normal care controls vs. outreach intervention. The number of people setting quit dates using NHS services, validated abstinence from smoking at four weeks, and stated abstinence at three and six months were assessed. The impact of the intervention on choice and adherence to treatments, attendance at clinic appointments and patient satisfaction were also assessed. RESULTS We were able to randomise geographical areas and deliver the outreach worker-based services. More Pakistani and Bangladeshi men made quit attempts with NHS services in intervention areas compared with control areas, rate ratio (RR) 1.32 (95%CI: 1.03-1.69). There was a small increase in the number of 4-week abstinent smokers in intervention areas (RR 1.30, 95%CI: 0.82-2.06). The proportion of service users attending weekly appointments was lower in intervention areas than control areas. No difference was found between intervention and control areas in choice and adherence to treatments or patient satisfaction with the service. The total cost of the intervention was £124,000; an estimated cost per quality-adjusted life year (QALY) gained of £8,500. CONCLUSIONS The intervention proved feasible and acceptable. Outreach workers expanded reach of smoking cessation services in diverse locations of relevance to Pakistani and Bangladeshi communities. The outreach worker model has the potential to increase community cessation rates and could prove cost-effective, but needs evaluating definitively in a larger, appropriately powered, randomised controlled trial. These future trials of outreach interventions need to be of sufficient duration to allow embedding of new models of service delivery. TRIAL REGISTRATION Current Controlled Trials ISRCTN82127540.
