Provision of E-Cigarettes for Smoking Cessation in Pregnancy: Perceptions and Experiences of Pregnant Women from Two UK Sites.

INTRODUCTION: Smoking in pregnancy is associated with negative health outcomes for both mothers and babies; e-cigarettes, which contain nicotine without hazardous tobacco, may offer an additional smoking cessation strategy for pregnant women. Although e-cigarettes are being increasingly offered within services, there is limited understanding about whether e-cigarettes can improve smoking cessation support for pregnant individuals. This study aimed to explore service users' experiences of using e-cigarettes as a tool for smoking cessation during pregnancy. METHODS: Semi-structured interviews were conducted with 14 women who had accepted one of two pilots and were analysed using inductive reflexive thematic analysis. The findings from each site were integrated to develop qualitative insight. RESULTS: Participants largely had positive perceptions of the free and easy-to-use e-cigarette, preferring it to nicotine replacement therapies. The desire to have a healthy pregnancy and baby and the inclusion of non-judgemental behavioural support facilitated motivation to quit. Many participants reduced or quit tobacco use, with positive social and health implications reported. However, numerous barriers to quitting were present and intentions about long-term quitting of combustible cigarettes and e-cigarettes were mixed and uncertain. CONCLUSIONS: Providing e-cigarettes within smoking cessation services was indicated to be a positive and effective strategy for pregnant women trying to quit tobacco. However, numerous barriers to quitting and staying quit remained, suggesting scope for further improvements to smoking cessation support for pregnant women.

Medications for Opioid Use Disorder for Youth: Patient, Caregiver, and Clinician Perspectives.

PURPOSE: Clinical trial data support use of medications for opioid use disorder (MOUD) in adolescents and young adults ("youth"), but qualitative data are lacking on the acceptability and importance of MOUD to youth, caregivers, and clinicians. We assessed how these stakeholders viewed the role of MOUD in treatment and recovery. METHODS: We recruited youth aged from 15 to 25 years with opioid use disorder who had received buprenorphine, naltrexone, or methadone and caregivers from a primary care-based youth addiction treatment program. We also recruited clinicians with addiction expertise from social work, nursing, pediatrics, internal medicine, and psychiatry. We conducted semistructured interviews assessing special considerations for MOUD use in youth. Three coders performed inductive and deductive thematic analysis of transcripts. RESULTS: Among 37 participants, including 15 youth (age range, 17-25 years), nine caregivers, and 13 clinicians, we identified three themes. (1) Medications support recovery in the short term: Youth described MOUD as beneficial in managing withdrawal symptoms. Notably, some youth and caregivers preferred to limit MOUD duration. (2) Medication adherence is affected by type of medication, dosing regimen, and route of administration. Participants endorsed long-acting, injectable MOUD for ease of use and youth's ability to continue engagement in "normal activities" without daily medication. (3) Caregiver involvement can support medication decisions and adherence. Youth and some clinicians described the need to assess caregiver involvement before incorporating them into treatment; caregivers and other clinicians described caregivers as critical in supporting accountability. DISCUSSION: MOUD is evidence-based, and its provision should be developmentally responsive and youth- and family-centered, incorporating caregivers when appropriate.

Pharmacogenomics implementation across multiple clinic settings: a qualitative evaluation.

Aim: To advance clinical adoption and implementation of pharmacogenomics (PGx) testing, barriers and facilitators to these efforts must be understood. This study identified and examined barriers and facilitators to active implementation of a PGx program across multiple clinic settings in an academic healthcare system. Materials & methods: 28 contributors to the PGx implementation (e.g., clinical providers, informatics specialists) completed an interview to elicit their perceptions of the implementation. Results: Qualitative analysis identified several barriers and facilitators that spanned different stages of the implementation process. Specifically, unclear test payment mechanisms, decision support tool development, rigid workflows and provider education were noted as barriers to the PGx implementation. A multidisciplinary implementation team and leadership support emerged as key facilitators. Furthermore, participants also suggested strategies to overcome or maintain these factors. Conclusion: Assessing real-world implementation perceptions and suggested strategies from a range of implementation contributors facilitates a more comprehensive framework and best-practice guidelines for PGx implementation.

Co-Created Solutions for Perinatal Professionals and Childbearing Needs for People with Hypermobile Ehlers-Danlos Syndrome and Hypermobility Spectrum Disorders.

Individuals living with hypermobile Ehlers-Danlos syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD) have reported feeling discredited and unsupported by healthcare professionals. However, the level of knowledge about hEDS/HSD among maternity staff remains unknown. Informed by patient and public involvement, this research aimed to investigate maternity staff's knowledge and confidence in supporting people with hEDS/HSD, examine people with hEDS/HSD's experiences of perinatal care, and co-create tools to help maternity staff support people childbearing with hEDS/HSD. Two online mixed-methods international surveys were completed by childbearing people with hEDS/HSD (N = 955) and maternity staff (N = 307). This was followed by the co-creation of three tools with 17 co-creators and a design team. Two main qualitative themes were identified through thematic analysis: (1) a need for recognition of hEDS/HSD in perinatal care and (2) the delivery of appropriate individualised perinatal care. Quantitatively, people with hEDS/HSD perceived maternity professionals to have a low level of knowledge about the conditions. Respectively, maternity staff reported low levels of confidence in supporting people with hEDS/HSD. The co-created tools provide applicable outputs for both education and practice and include an i-learn module hosted by the Royal College of Midwives, a tool for perinatal records, and infomercials.

Childbearing with Hypermobile Ehlers-Danlos Syndrome and Hypermobility Spectrum Disorders: A Large International Survey of Outcomes and Complications.

One in 20 births could be affected by hypermobile Ehlers-Danlos syndrome or Hypermobility Spectrum Disorders (hEDS/HSD); however, these are under-diagnosed and lacking research. This study aimed to examine outcomes and complications in people childbearing with hEDS/HSD. A large online international survey was completed by women with experience in childbearing and a diagnosis of hEDS/HSD (N = 947, total pregnancies = 1338). Data were collected on demographics, pregnancy and birth outcomes and complications. Participants reported pregnancies in the UK (N = 771), USA (N = 364), Australia (N = 106), Canada (N = 60), New Zealand (N = 23) and Ireland (N = 14). Incidences were higher in people with hEDS/HSD than typically found in the general population for pre-eclampsia, eclampsia, pre-term rupture of membranes, pre-term birth, antepartum haemorrhage, postpartum haemorrhage, hyperemesis gravidarum, shoulder dystocia, caesarean wound infection, postpartum psychosis, post-traumatic stress disorder, precipitate labour and being born before arrival at place of birth. This potential for increased risk related to maternal and neonatal outcomes and complications highlights the importance of diagnosis and appropriate care considerations for childbearing people with hEDS/HSD. Recommendations include updating healthcare guidance to include awareness of these possible complications and outcomes and including hEDS/HSD in initial screening questionnaires of perinatal care to ensure appropriate consultation and monitoring can take place from the start.

How and to what extent did the Coventry City of Culture 'City Host' volunteer programme effect the volunteers' mental wellbeing? A qualitative study.

BACKGROUND: A team of volunteers, known as City Hosts, were recruited to support UK City of Culture 2021 awarded to Coventry. City Hosts held various roles facilitating cultural event delivery and promoting a positive experience for visitors. This study aimed to (i) understand how and to what extent the volunteering programme impacted volunteer subjective wellbeing, and (ii) explore the mechanisms of change and intermediate outcomes between volunteering and subjective wellbeing. METHODS: This qualitative study comprised inductive and deductive analysis of data collected through semi-structured interviews, conducted between December 2021-May 2022 with City Hosts. This was complimented with secondary qualitative analysis of free text responses within Monitoring and Evaluation data collected from City Hosts in surveys conducted in August and November 2021, and April 2022. RESULTS: Approximately 180 City Hosts responded to the free text questions in each survey and 27 completed interviews. Analysis of data collected from City Hosts suggested positive wellbeing impacts from volunteering and supported theorised pathways to improved wellbeing. Strengths of the City Host programme included (i) facilitating the full range of mechanisms of change that mediate improved volunteer wellbeing, particularly promoting social connections and developing a strong role and group identity and (ii) flexibility around what volunteers do, how much, and how often. CONCLUSIONS: This study offers lessons for others designing volunteering programmes who wish to promote wellbeing among associated volunteers. We also offer evidence that exposure to culture may be one mechanism by which volunteering can improve wellbeing.

Structured Engagement of Community Partners to Revise a Pregnancy Options Counseling Curriculum for Pediatric Residents.

OBJECTIVE: The engagement of community partners, including patients, is increasingly recognized as important in developing medical education curricula. Structured methodology for partner engagement in curriculum development is lacking in the existing literature. This article describes a structured approach to engaging community partners to provide input on revising a curriculum for pediatric residents about pregnancy options counseling with adolescents. METHODS: We used the five-step Method for Program Adaptation through Community Engagement: (1) development of a panel of community partners including patients and professionals, (2) and (3) partner evaluation of the existing curriculum and recommendations for revisions, (4) summarization of partner feedback, and (5) development of the revised curriculum. We surveyed partners about their perceived impact on the revision and satisfaction with the process. RESULTS: Seventeen partners participated. Five experienced adolescent pregnancy, while the remaining 12 included healthcare and social service professionals. All partners provided multiple recommendations, generating 124 discrete recommendations. Twenty recommendations were suggested by multiple individuals. The authors reviewed all recommendations by category during consensus meetings and determined which recommendations would be incorporated into the revised curriculum to meet stated learning objectives. We implemented 14 of these 20 recommendations, including adding a values clarification exercise, information about mental health crisis resources, and more detail about adoption. We also incorporated 15 individual recommendations pertaining to curriculum clarity. Recommendations from professionals and patients were similar. Fourteen out of 17 participants completed the survey at the close of the project. All respondents understood their roles, were satisfied with their degree of engagement, and felt that their expectations for participation were met or exceeded. CONCLUSIONS: This study describes a methodology for a formal process to engage community partners in curriculum development and revision processes. Such methodology can ensure that medical education curricula are optimally attuned to the needs of key community members and integrate the patient's voice.

Household Composition, Income, and Fast-Food Consumption among Black Women and Men.

Black adults are more likely to consume meals from fast-food restaurants than other racial/ethnic groups with implications for disparities in dietary quality and obesity outcomes. Family and economic characteristics are associated with fast-food consumption. The aim of this study was to determine the association between household composition, income, and fast-food consumption among Black women and men. A cross-sectional, secondary analysis of nationally representative data from the 2011-2018 National Health and Nutrition Examination Survey using multiplicative interaction terms and negative binomial regressions were used to assess whether household income moderated associations between number of children or older adults in the household and number of weekly fast-food meals consumed. Household composition was not associated with fast-food consumption among Black women overall. Yet, demonstrated by a significant interaction (incidence rate ratio (IRR) = 3.41, 95% confidence interval (CI) = 1.59-7.32), Black women with higher household income (≥ $75,000) and multiple young children consumed more fast-food compared to women with no children in the household. In contrast, Black men with one school-aged child in the home consumed fewer weekly fast-food meals than men with no school-aged children in the home (IRR = 0.69, 95% CI = 0.51-0.93). A significant interaction between number of older adults in the household and household income ≥ $75,000 (IRR = 3.56, 95% CI = 1.59-8.01) indicated that Black men with lower incomes and at least one older adult in the household consumed fewer weekly fast-food meals. These findings demonstrate that household composition and household income interact on fast-food consumption among Black women and men. Future studies should interrogate these differences, while programs and policies can be informed by the results of this study.

How Notifications Affect Engagement With a Behavior Change App: Results From a Micro-Randomized Trial.

BACKGROUND: Drink Less is a behavior change app to help higher-risk drinkers in the United Kingdom reduce their alcohol consumption. The app includes a daily notification asking users to "Please complete your drinks and mood diary," yet we did not understand the causal effect of the notification on engagement nor how to improve this component of Drink Less. We developed a new bank of 30 new messages to increase users' reflective motivation to engage with Drink Less. This study aimed to determine how standard and new notifications affect engagement. OBJECTIVE: Our objective was to estimate the causal effect of the notification on near-term engagement, to explore whether this effect changed over time, and to create an evidence base to further inform the optimization of the notification policy. METHODS: We conducted a micro-randomized trial (MRT) with 2 additional parallel arms. Inclusion criteria were Drink Less users who consented to participate in the trial, self-reported a baseline Alcohol Use Disorders Identification Test score of ≥8, resided in the United Kingdom, were aged ≥18 years, and reported interest in drinking less alcohol. Our MRT randomized 350 new users to test whether receiving a notification, compared with receiving no notification, increased the probability of opening the app in the subsequent hour, over the first 30 days since downloading Drink Less. Each day at 8 PM, users were randomized with a 30% probability of receiving the standard message, a 30% probability of receiving a new message, or a 40% probability of receiving no message. We additionally explored time to disengagement, with the allocation of 60% of eligible users randomized to the MRT (n=350) and 40% of eligible users randomized in equal number to the 2 parallel arms, either receiving the no notification policy (n=98) or the standard notification policy (n=121). Ancillary analyses explored effect moderation by recent states of habituation and engagement. RESULTS: Receiving a notification, compared with not receiving a notification, increased the probability of opening the app in the next hour by 3.5-fold (95% CI 2.91-4.25). Both types of messages were similarly effective. The effect of the notification did not change significantly over time. A user being in a state of already engaged lowered the new notification effect by 0.80 (95% CI 0.55-1.16), although not significantly. Across the 3 arms, time to disengagement was not significantly different. CONCLUSIONS: We found a strong near-term effect of engagement on the notification, but no overall difference in time to disengagement between users receiving the standard fixed notification, no notification at all, or the random sequence of notifications within the MRT. The strong near-term effect of the notification presents an opportunity to target notifications to increase "in-the-moment" engagement. Further optimization is required to improve the long-term engagement. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR2-10.2196/18690.

Dissociations between face identity and face expression processing in developmental prosopagnosia.

Individuals with developmental prosopagnosia (DPs) experience severe and lifelong deficits recognising faces, but whether their deficits are selective to the processing of face identity or extend to the processing of face expression remains unclear. Clarifying this issue is important for understanding DP impairments and advancing theories of face processing. We compared identity and expression processing in a large sample of DPs (N = 124) using three different matching tasks that each assessed identity and expression processing with identical experimental formats. We ran each task in upright and inverted orientations and we measured inversion effects to assess the integrity of upright-specific face processes. We report three main results. First, DPs showed large deficits at discriminating identity but only subtle deficits at discriminating expression. Second, DPs showed a reduced inversion effect for identity but a normal inversion effect for expression. Third, DPs' performance on the expression tasks were linked to autism traits, but their performance on the identity tasks were not. These results constitute several dissociations between identity and expression processing in DP, and they are consistent with the view that the core impairment in DP is highly selective to identity.

Preferences and Experiences Regarding Pregnancy Options Counseling in Adolescence and Young Adulthood: A Qualitative Study.

PURPOSE: Perspectives of adolescents and young adults (AYAs) experiencing pregnancy options counseling (POC) are absent from the literature. This study explores AYA experiences and preferences related to POC to inform best practice guidelines. METHODS: We conducted semistructured phone interviews in 2020-2021 among US-based individuals, 18-35 years old, who experienced a pregnancy less than 20 years of age. We performed qualitative descriptive analysis of positive and negative attributes of AYA's experiences with POC. RESULTS: Fifty participants reported 59 pregnancies (16 parenting, 19 abortions, 18 adoptions, three miscarriages) between the ages of 13 and 19 years. Positive attributes of POC experienced included: (1) provider communication that was compassionate, respectful, supportive, and attentive to nonverbal cues; (2) provider neutrality; (3) discussion of all pregnancy options; (4) asking about feelings, choice, life plans, and additional supports; (5) provision of informational materials; and (6) warm handoffs/follow-up facilitation. Negative attributes of POC experienced included: (1) judgmental, impersonal, or absent communication; (2) lack of counseling on all options and/or coercive/directive counseling; (3) insufficient time and supportive resources; and (4) confidentiality concerns. We identified no differences in these perspectives across pregnancy outcomes reported. Participants generally desired counseling about all options, with rare exceptions of ambivalence. DISCUSSION: Individuals who experienced an adolescent pregnancy described similar positive and negative attributes of POC regardless of preferred pregnancy outcome. Their perspectives highlight how crucial interpersonal communication skills are for effective POC for AYA. POC training across health care specialties should emphasize confidential, compassionate, and nonjudgmental care for AYA patients.

Unintentional overdoses: understanding the fentanyl landscape and reducing harm.

PURPOSE OF REVIEW: Adolescent and young adult overdoses and overdose fatalities continue to increase despite reductions in self-reported substance use. This review aims to explore factors contributing to this overdose epidemic, highlight signs of overdose and the role of the overdose reversal medication naloxone, and provide recommendations for practice change to support patients and decrease their risk of unintentional overdose. RECENT FINDINGS: The potent opioid fentanyl is a common contaminant in nonopioid substances, as well as in heroin and counterfeit pills, heightening risk of fatal overdose. Adolescents and young adults who die of overdose are rarely engaged in substance use disorder treatment. Medications for opioid use disorder are effective at reducing risk of fatal overdose but are underutilized, as is the opioid reversal medication naloxone. SUMMARY: Pediatric clinician engagement in harm reduction with adolescents and young adults, starting with screening through a confidential interview, may enhance pathways to care and reduce the risk of overdose.

Health Care and Adoption Service Experiences of People Who Placed Children for Adoption During Adolescence: A Qualitative Study.

STUDY OBJECTIVE: To understand the perspectives of people who placed children for adoption during adolescence DESIGN: We conducted qualitative interviews with adults who placed children for adoption during adolescence. We recruited participants through social media and two adoption-related organizations. We audio-recorded and transcribed interviews. Using thematic analysis, 2 investigators coded the transcripts and identified themes. SETTING: Telephone interviews PARTICIPANTS: Adults ages 18-35 years old who placed children for adoption before they were 20 years old INTERVENTIONS: Semi-structured telephone interviews MAIN OUTCOME MEASURES: Qualitative data RESULTS: We conducted interviews with 18 individuals (median age of 32 years; range 21-35 years). The median age at pregnancy was 18 years (range 13-19 years). Seventeen participants identified as female and one as nonbinary. Themes included the following: (1) Negative experiences with counseling included limited empowerment to make choices about pregnancy or adoption options; (2) negative experiences with counseling included limited information about practical or financial support for pregnant adolescents; (3) negative experiences with the health care system included insensitivity or lack of awareness of the adoption plan at delivery; (4) positive experiences with counseling included comprehensive unbiased options counseling and adoption counseling emphasizing birth parent choice in openness and family placement; (5) positive experiences included longitudinal emotional support during pregnancy, particularly in ways that normalized adoption placement; and (6) participants desired therapy and/or psychological support following adoption placement. CONCLUSIONS: Individuals who chose adoption after adolescent pregnancy described positive and negative encounters with health care and adoption professionals that could serve as targets to improve the overall care experience for this population.

Comparing Practices Used in Overdose Fatality Review Teams to Recommended Implementation Guidelines.

OBJECTIVES: Overdose fatality review teams are a public health and public safety collaboration that reviews fatality cases using a multidisciplinary team to provide recommendations for overdose prevention. No research exists on the case review practices currently being used in these programs. DESIGN: We administered a cross-sectional survey measuring case review practices and perceptions to a convenience sample of overdose fatality review teams. SETTING: We administered the online survey to participants at a national virtual forum on overdose fatality review. PARTICIPANTS: In this study, we examined 30 county-level overdose fatality review teams from 6 states who completed the survey. MAIN OUTCOME MEASURES: We developed measures of case review practices from an overdose fatality review implementation guide. We provided descriptive statistics on the survey items used to measure these practices and examined how practice uptake varied by overdose fatality review team characteristics. RESULTS: Most overdose fatality review teams had adequate representation and membership, but none adhered to all of the practices measured from the implementation guide. The largest gap was in perceived effectiveness and implementation of case review recommendations. In addition, teams that had been reviewing cases for longer reported more adherence to recommended practices. CONCLUSIONS: Overdose fatality case review is a collaboration between local public health and public safety agencies that holds great promise. However, these teams will require additional training and technical assistance with local community support to ensure that recommendations are actionable.

Standing Crop, Turnover, and Production Dynamics of Macrocystis pyrifera and Understory Species Hedophyllum nigripes and Neoagarum fimbriatum in High Latitude Giant Kelp Forests.

Production rates reported for canopy-forming kelps have highlighted the potential contributions of these foundational macroalgal species to carbon cycling and sequestration on a globally relevant scale. Yet, the production dynamics of many kelp species remain poorly resolved. For example, productivity estimates for the widely distributed giant kelp Macrocystis pyrifera are based on a few studies from the center of this species' range. To address this geospatial bias, we surveyed giant kelp beds in their high latitude fringe habitat in southeast Alaska to quantify foliar standing crop, growth and loss rates, and productivity of M. pyrifera and co-occurring understory kelps Hedophyllum nigripes and Neoagarum fimbriatum. We found that giant kelp beds at the poleward edge of their range produce ~150 g C · m-2 · year-1 from a standing biomass that turns over an estimated 2.1 times per year, substantially lower rates than have been observed at lower latitudes. Although the productivity of high latitude M. pyrifera dwarfs production by associated understory kelps in both winter and summer seasons, phenological differences in growth and relative carbon and nitrogen content among the three kelp species suggests their complementary value as nutritional resources to consumers. This work represents the highest latitude consideration of M. pyrifera forest production to date, providing a valuable quantification of kelp carbon cycling in this highly seasonal environment.

"I Feel Happy Again": Methylphenidate Supports Health-Related Quality of Life in Survivors of Pediatric Brain Tumor.

BACKGROUND: The deleterious impact upon the cognitive development of survivors of pediatric brain tumors (PBT) is well documented. Impairment in cognitive function is associated with reduced health-related quality of life (HRQoL), such that survivors of PBT report difficulties in multiple distinct domains and an overall reduced quality of life. Studies of the use of methylphenidate in survivors of PBT to alleviate impairment in cognitive functions have shown some success. The current study aimed to explore the impact upon HRQoL in survivors of PBT of a trial of psychostimulant medication. METHOD: Data were collected from 12 pediatric neuro-oncology patients aged 7-17 years receiving methylphenidate treatment. HRQoL was measured using the PEDS QL quality of life self-report measure and a semi-structured questionnaire-based interview. RESULTS: Analyses of data demonstrates benefit to five domains associated with HRQoL: social, emotional, academic, physical, and cognition. CONCLUSION: Survivors of PBT reported favorable views as to the subjective benefit of methylphenidate on post-treatment impairment of HRQoL. This medication may offer the potential for restoration of a sense of 'normality' of function following cancer treatment in this clinical population.

Examining the Efficacy of Project ECHO to Improve Clinicians' Knowledge and Preparedness to Treat Adolescent Vaping.

As adolescent vaping reaches epidemic rates in the United States, it is imperative that pediatric clinicians have access to medical knowledge on best practices for screening, assessing, and treating vaping-related substance use. The Teen Vaping ECHO (Extension for Community Healthcare Outcomes) program was developed to offer practical learning sessions focused on clinical management of adolescent vaping. This study describes the development, implementation, and evaluation of the program's impact on participants' knowledge, attitudes, and practices regarding treatment of adolescent vaping from registration to the end of the series. Participants were generally knowledgeable about vaping at registration and reported significant increases in comfort talking with patients about vaping, counseling patients on nicotine replacement products, and frequency of implementing best-practice screening strategies at the end of the series. This study suggests ECHO programs focused on improving clinical management of adolescent vaping may increase accessibility of evidence-based care and reduce harms associated with vaping in youth.

The English national health service diabetes prevention programme (NHS DPP): A scoping review of existing evidence.

AIMS: The English National Health Service Diabetes Prevention Programme (NHS DPP) is commissioned by NHS England and has been rolled out across England to adults identified as being at high risk of type 2 diabetes. The present scoping review aimed to identify the extent and nature of evidence to date on the NHS DPP and describe what the evidence has reported. METHODS: A scoping review involving searches of various sources (including MEDLINE, CINAHL, MediArXiv, Google Scholar and GreyLit) was conducted on 31 August 2021 and repeated on 09 February 2022. Only articles reporting on the NHS DPP made available since 2015 were eligible for inclusion. RESULTS: 65 articles were included. Of these, 37 were journal publications. Most articles were made available in 2018 and 2020 (total n = 25). The majority of articles reported on uptake and retention (n = 27) whilst others reported on implementation considerations (n = 24), programme outcomes (n = 21), stakeholder experience (n = 8) and screening and referral processes (n = 3). Various research methods were reported and included qualitative (n = 9) and document analysis (n = 8). Articles revealed preliminary evidence on service user characteristics, rates of referral, uptake and retention as well as how far the NHS DPP is being delivered in line with its evidence base and service specification. CONCLUSIONS: The evidence is accumulating on NHS DPP uptake and retention most, with emerging evidence on programme outcomes (such as weight loss and HbA1c). More evidence is warranted on stakeholder experience to decipher how to overcome low initial and long-term engagement reported by the current evidence base.
