RCT-based Social Return on Investment (SROI) of a Home Exercise Program for People With Early Dementia Comparing In-Person and Blended Delivery Before and During the COVID-19 Pandemic.

Regular exercise and community engagement may slow the rate of function loss for people with dementia. However, the evidence is uncertain regarding the cost-effectiveness and social return on investment (SROI) of home exercise with community referral for people with dementia. This study aimed to compare the social value generated from the in-person PrAISED program delivered before March 2020 with a blended PrAISED program delivered after March 2020. SROI methodology compared in-person and blended delivery formats of a home exercise program. Stakeholders were identified, a logic model was developed, outcomes were evidenced and valued, costs were calculated, and SROI ratios were estimated. Five relevant and material outcomes were identified: 3 outcomes for patient participants (fear of falling, health-related quality of life, and social connection); 1 outcome for carer participants (carer strain), and 1 outcome for the National Health Service (NHS) (health service resource use). Data were collected at baseline and at 12-month follow-up. The in-person PrAISED program generated SROI ratios ranging from £0.58 to £2.33 for every £1 invested. In-person PrAISED patient participants gained social value from improved health-related quality of life, social connection, and less fear of falling. In-person PrAISED carer participants acquired social value from less carer strain. The NHS gained benefit from less health care service resource use. However, the blended PrAISED program generated lower SROI ratios ranging from a negative ratio to £0.08:£1. Compared with the blended program, the PrAISED in-person program generated higher SROI ratios for people with early dementia. An in-person PrAISED intervention with community referral is likely to provide better value for money than a blended one with limited community referral, despite the greater costs of the former.Trial registration: ISRCTN Registry ISRCTN15320670.

Single-centre, single-blinded, randomised, parallel group, feasibility study protocol investigating if mandibular advancement device treatment for obstructive sleep apnoea can reduce nocturnal gastro-oesophageal reflux (MAD-Reflux trial).

INTRODUCTION: Just under half of patients with obstructive sleep apnoea (OSA) also have gastro-oesophageal reflux disease (GORD). These conditions appear to be inter-related and continual positive airway pressure (CPAP) therapy, the gold standard treatment for OSA to prevent airway collapse, has been shown to reduce GORD. As the impact of mandibular advancement devices, a second-line therapy for OSA, on GORD has yet to be investigated, a feasibility study is needed prior to a definitive trial. METHODS: This will be a single-centre, single-blinded, tertiary-care based, interdisciplinary, parallel randomised controlled study. Potential OSA participants presenting to the sleep department will be pre-screened for GORD using validated questionnaires, consented and invited to receive simultaneous home sleep and oesophageal pH monitoring. Those with confirmed OSA and GORD (n=44) will be randomly allocated to receive either CPAP (n=22) or MAD therapy (n=22). Following successful titration and 3 weeks customisation period, participants will repeat the simultaneous sleep and oesophageal pH monitoring while wearing the device. The number of patients screened for recruitment, drop-out rates, patient feedback of the study protocol, costs of interventions and clinical information to inform a definitive study design will be investigated. ETHICS AND DISSEMINATION: Health Research Authority approval has been obtained from the Nottingham 2 Research Ethics Committee, ref:22/EM/0157 and the trial has been registered on ISRCTN (https://doi.org/10.1186/ISRCTN16013232). Definitive findings about the feasibility of doing 24 hour pH oesophageal monitoring while doing a home sleep study will be disseminated via clinical and research networks facilitating valuable insights into the simultaneous management of both conditions.

Association between medication adherence and cardiovascular outcomes among acute coronary syndrome patients.

BACKGROUND: Medication adherence to guideline-recommended therapy is important and associated with a lower rate of death and major adverse cardiovascular events (MACE) among patients with acute coronary syndrome (ACS). OBJECTIVE: This retrospective study aimed to evaluate medication adherence in four classes of guideline-recommended medicines (antiplatelets, ACEIs/ARBs, beta-blockers, and statins) among patients discharged with ACS and to assess the association between patients' adherence to each medication and the occurrence of MACE including all causes of death, myocardial infarction, unstable angina, heart failure, stroke, atrial fibrillation or coronary revascularization. METHODS: The electronic medical records of patients with ACS admitted at a tertiary teaching hospital in northern Thailand between January 1, 2010 and December 31, 2015 were reviewed. Medication adherence was evaluated from a hospital database of prescription refills using the medication gap technique with ≥90% as a cut-off for full adherence and <90% as partial adherence. RESULTS: Of 256 patients, the mean age was 65.9 (±13.0) years. The median percentage of medication adherence in the dual antiplatelet group, ACEI/ARB group, beta-blocker group, and statin group were 94.7, 93.6, 93.1, and 93.1%, respectively. Sixty-two patients (24.2%) experienced MACE after a median follow-up of 1.5 years. Patients with ≥90% adherence of beta-blockers had a significantly lower risk of MACE than those with <90% adherence: HR = 0.47, 95% Cl, 0.26-0.87, p = 0.016, adjusted with potential confounders. No other significant associations were observed. CONCLUSIONS: Medication adherence of each medication was above 90%. ACS patients with at least 90% adherence to beta-blockers had a lower risk of MACE than those having less than 90% adherence, but no other significant associations were found for other medications.
