Recruitment and implementation challenges were common in stepped-wedge cluster randomized trials: Results from a methodological review.

Objective: To explore challenges in recruitment and intervention implementation in recent stepped-wedge cluster randomized trials (SW-CRTs).

Study Design And Setting: We searched PubMed to identify primary reports of SW-CRTs (2019-2020). Two reviewers independently screened studies and extracted data from each report.

External validation of the 80+ score and comparison with three clinical scores identifying patients at least 75 years old at risk of unplanned readmission within 30 days after discharge.

Aim Of The Study: A potentially avoidable readmission is an unplanned readmission occurring within 30 days of discharge. As 20% of hospitalised elderly patients are rehospitalised as an unplanned readmission, it is necessary to identify with a clinical score those patients who are at risk of readmission and need discharge interventions as a priority. The main objective of this study was to externally validate and compare the 80+ score with the three other scores predicting the risk of unplanned readmission.
