BackgroundMany young adults with Type 1 diabetes experience poor outcomes. The aim of this systematic review was to synthesize the evidence regarding the effectiveness of interventions aimed at improving clinical, behavioural or psychosocial outcomes for young adults with Type 1 diabetes.MethodsElectronic databases were searched. Any intervention studies related to education, support, behaviour change or health service organizational change for young adults aged between 15‐30 years with Type 1 diabetes were included. A narrative synthesis of all studies was undertaken due to the large degree of heterogeneity between studies.ResultsEighteen studies (of a possible 1700) were selected and categorized: Health Services Delivery (n = 4), Group Education and Peer Support (n = 6), Digital Platforms (n = 4) and Diabetes Devices (n = 4). Study designs included one randomized controlled trial, three retrospective studies, seven feasibility/acceptability studies and eight studies with a pre/post design. Continuity, support, education and tailoring of interventions to young adults were the most common themes across studies. HbA1c was the most frequently measured outcome, but only 5 of 12 studies that measured it showed a significant improvement.ConclusionBased on the heterogeneity among the studies, the effectiveness of interventions on clinical, behavioural and psychosocial outcomes among young adults is inconclusive. This review has highlighted a lack of high‐quality, well‐designed interventions, aimed at improving health outcomes for young adults with Type 1 diabetes.

Regular clinic attendance is recommended to facilitate self-management of diabetes. Poor attendance is common among young adults with type 1 diabetes mellitus (DM). This systematic review aimed to produce a narrative synthesis of the evidence regarding factors which promote or impede regular attendance at adult diabetes clinics among young adults (15-30 years) with type 1 DM. Studies reporting facilitators and barriers to clinic attendance were identified by searching four electronic databases, checking reference lists, and contacting diabetes research networks. A total of 12 studies (8 quantitative and 4 qualitative) met the inclusion criteria. Young adult's experiences transitioning from paediatric to adult diabetes care can influence attendance at the adult clinic positively if there is a comprehensive transition programme in place, or negatively if the two clinics do not communicate and provide adequate support. Post-transition, relationship development and perceptions of the value of attending the clinic are important for regular attendance. Controlled research is required to better understand decisions to attend or not attend outpatient services among people with chronic conditions. Service delivery must be sensitive to the developmental characteristics of young adults and tailored support may be required by young adults at greatest risk of non-attendance.

BackgroundAchieving consensus from a range of relevant stakeholders about an agreed set of core outcomes to be measured and reported as a minimum in clinical trials has the potential to enhance evidence synthesis and make findings more relevant and applicable. Intervention research to improve outcomes for young adults with type 1 diabetes (T1DM) is hampered by inconsistent use of outcome measures. This population frequently struggles to manage their condition and reports suboptimal clinical outcomes. Our aim was to conduct an international, e-Delphi consensus study to identify a core outcome set (COS) that key stakeholders (young adults with T1DM, diabetes health professionals, diabetes researchers and diabetes policy makers) consider as essential outcomes for future intervention research.MethodsUsing a list of 87 outcomes generated from a published systematic review, we administered two online surveys to a sample of international key stakeholders. Participants in the first survey (survey 1; n = 132) and the second survey (survey 2; n = 81) rated the importance of the outcomes. Survey 2 participants received information on total mean rating for each outcome and a reminder of their personal outcome ratings from Survey 1. Survey 2 results were discussed at a consensus meeting and participants (n = 12: three young adults with T1DM, four diabetes health professionals, four diabetes researchers and one diabetes policy maker) voted on outcomes. Final core outcomes were included provided that 70% of consensus group participants voted for their inclusion.ResultsEight core outcomes were agreed for inclusion in the final COS: measures of diabetes-related stress; diabetes-related quality of life; number of severe hypoglycaemic events; self-management behaviour; number of instances of diabetic ketoacidosis (DKA); objectively measured glycated haemoglobin (HbA1C); level of clinic engagement; and perceived level of control over diabetes.ConclusionsThis study is the first to identify a COS for inclusion in future intervention trials to improve outcomes for young adults with T1DM. Use of this COS will improve the quality of future research and increase opportunities for evidence synthesis. Future research is necessary to identify the most robust outcome measure instruments.Electronic supplementary materialThe online version of this article (doi:10.1186/s13063-017-2364-y) contains supplementary material, which is available to authorized users.

Plain English summaryMany young adults with type 1 diabetes (T1D) find it hard to control their blood glucose levels. With lots of things going on in their lives, their diabetes is often not the most important thing to them. That means they do not always take care of their T1D, for example by going to clinic appointments. Young adults with T1D do not usually get the chance to make suggestions on how to improve diabetes services. Being involved could help young adults to shape the diabetes care services that support them. Since 2014 a diabetes research team based in Galway has been looking at ways to improve how diabetes services are delivered to young adults. Eight young adults (aged 18-25 years) with T1D called the Young Adult Panel (YAP) are members of this team and have helped design the "D1 Now" intervention which aims to improve diabetes services. The YAP came up with questions to ask other young adults with T1D, their families and friends and healthcare providers about their experiences of healthcare services and how these could be improved. The YAP also shared messages from the research at national conferences and on local radio. They helped with writing sections of a grant application to take this research work forward. Our experience has shown the importance of involving young adults with T1D in helping to design research focusing on ways to improve their diabetes service that will help them and other young adults to live with diabetes in the future. O'Hara et al. Research Involvement and Engagement (2017) 3:21 DOI 10.1186/s40900-017-0068-9(Continued from previous page) Abstract Background Research indicates that young adults (18-25 year olds) with type 1 diabetes (T1D) often disengage from health services and their general diabetes management. Involving young adults with T1D in co-designing research to develop a behaviour change intervention to improve engagement with health services could potentially improve overall self management and health. A local youth mental health organisation called Jigsaw, Galway developed a very successful model for involving users in service design and development. Based on this model, the aim was to form a Young Adult Panel (YAP) of 18-25 year olds with T1D and involve them in all aspects of a study to develop an intervention to improve health and wellbeing for young adults with T1D called D1 Now.Methods Recruitment of young adults was achieved through a multimedia campaign. A consultation event was organised, followed by interviews with interested young adults. A panel of 8 members was selected. Following initial training for YAP members in committee skills and an introduction to different research methods and terms, YAP members participated in different stages of the research process. They were represented on the research study steering group and attended research meetings. They developed research materials, reviewed and interpreted research findings and helped develop the online platform to enhance engagement between young adults and their diabetes healthcare providers....

Objectives This systematic review aimed to describe medication non-adherence among people living with multimorbidity according to the current literature, and synthesise predictors of non-adherence in this population. Methods A systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses. PubMed, EMBASE, CINAHL and PsycINFO were searched for relevant articles published in English language between January 2009 and April 2019. Quantitative studies reporting medication non-adherence and/or predictors of non-adherence among people with two or more chronic conditions were included in the review. A meta-analysis was conducted with a subgroup of studies that used an inclusive definition of multimorbidity to recruit participants, rather than seeking people with specific conditions. Remaining studies reporting prevalence and predictors of non-adherence were narratively synthesised. Results The database search produced 10 998 records and a further 75 were identified through other sources. Following full-text screening, 178 studies were included in the review. The range of reported non-adherence differed by measurement method, at 76.5% for self-report, 69.4% for pharmacy data, and 44.1% for electronic monitoring. A meta-analysis was conducted with eight studies (n=8949) that used an inclusive definition of multimorbidity to recruit participants. The pooled prevalence of non-adherence was 42.6% (95% CI: 34.0 - 51.3%, k=8, I2=97%, p<0.01). The overall range of non-adherence was 7.0%–83.5%. Frequently reported correlates of non-adherence included previous non-adherence and treatment-related beliefs. Conclusions The review identified a heterogeneous literature in terms of conditions studied, and definitions and measures of non-adherence used. Results suggest that future attempts to improve adherence among people with multimorbidity should determine for which conditions individuals require most support. The variable levels of medication non-adherence highlight the need for more attention to be paid by healthcare providers to the impact of multimorbidity on chronic disease self-management.
