Exploring the impact of a Tele-health intervention on specific quality of life domains and psychological well-being in diabetic patients within the Whole Systems Demonstrator Questionnaire Study

Introduction: Much is written about the promise of Telehealth (TH) and there is great enthusiasm about its potential. However, many studies of TH do not meet orthodox quality standards. Evidence-based on assimilating findings from a few small trials of variable methodological quality presents equivocal findings and makes results difficult to interpret. Robust evidence to inform policy decisions is considered to be lacking (Ekeland et al., 2010). This remains the case when specific long-term conditions such as diabetes are considered with regards to health related quality of life (HRQoL) outcomes. The WSD study aimed to address some of these concerns. Aims: This study investigated the impact of TH on disease-specific HRQoL, generic HRQoL and psychological outcomes (anxiety and depression) in patients with diabetes, utilising longitudinal questionnaire data from the WSD Telehealth Study. Design: The WSD Telehealth Questionnaire Study is pragmatic cluster-randomised controlled trial evaluating a broad range of patientreported outcome measures. Participants were recruited from three sites in the UK (Cornwall, Kent and Newham). The current analyses focus on participants with diabetes. Methods: Over 400 participants with diabetes completed measures of disease-specific HRQoL (DHP), generic HRQoL (UK SF-12; EQ5D), anxiety (Brief STAI) and depression (CESD-10) at baseline. Shortand long-term follow-up assessments were conducted. Multi-level modelling analyses of difference in outcomes between trial arm groups and across time were conducted with appropriate covariates. Results and Conclusions: Findings and conclusions from the WSD Telehealth Study are embargoed until these analyses have been peerreviewed and accepted for publication.
