Design outcomes

Primary

MeasureTime frame
Patient readmission to the hospital measured using Hospital Episode Statistics (HES) data 90 days post hospital discharge

Secondary

MeasureTime frame
Patient-oriented secondary outcomes measures: 1. Mortality is measured using the Office of National Statistics (ONS) records 90 days post-hospital discharge 2. The number of hospital stays post-discharge is measured using Hospital Episode Statistic (HES) data 90 days post-hospital discharge 3. Quality of life is measured using the EuroQol EQ-5D-5L validated questionnaire at discharge and 90 days post-hospital discharge 4. Satisfaction with deprescribing is measured using a 13-item bespoke questionnaire as soon as possible post-hospital discharge Process secondary outcomes measures: 1. Number of regularly prescribed medicines at the point of leaving the ward is measured using site medical records at discharge 2. Number of prescribed medicines for ‘when required use’ at the point of leaving the ward is measured using hospital site medical records at discharge 3. Number of prescribed medicines that are stopped is measured using hospital-site medical records at discharge 4. Number of prescribed medicines with dosage reduced is measured using hospital site medical records at discharge 5. Number of stopped medicines that are restarted within three months of discharge is measured using community pharmacy dispensed medicines data 6. 90 days post-hospital discharge Economic secondary outcomes measures: 1. Costs/resource use for the intervention is measured using the fidelity framework/expert-opinion/study records during active study periods 2. Length of hospital stay for index admission is measured using site medical records at hospital discharge 3. Number of admissions in the follow-up period is measured using routine data at the end of the study
