RESUMO
INTRODUCTION: Improving discharge information dissemination may improve patients' health literacy of self-care and health outcomes, avoid unnecessary healthcare utilisation, and reduce the healthcare cost. This study aims to use an implementation science theory guided approach to examine the beliefs and behaviours of healthcare professionals regarding postdischarge information summary (PDIS) implementation in a public inpatient setting. METHODS AND ANALYSIS: A multistage study design involving qualitative inquiry and Delphi expert discussion will be used to systematically explore the perceived barriers in the four implemented hospitals and enable the full implementation of the PDIS in geriatric and medical care. The theoretical domains framework (TDF), behavioural change wheel and realistic evaluation framework will be used to guide the investigation of implementation. This study consists of three steps: (1) identifying barriers and enablers from an implementation perspective using a TDF-informed interview guide; (2) devising theory-based implementation strategy packages to facilitate the adoption and enhancement of PDIS by performing a strategy mapping exercise and (3) developing an effective implementation strategy package for scaling up PDIS in other target hospitals as well as other specialities using the Delphi expert discussion. The goal of this multistage study design is to identify the perspectives from healthcare professionals towards the PDIS implementation and explore their barriers and facilitators of the process in the pilot phase. The invited healthcare professionals would share their daily experience on providing PDIS to patient in various study hospitals with similar ward setting. The implementation of discharge intervention in a study setting through different steps to aid in the exploration and development of the modified implementation strategies for the adoption and enhancement of PDIS in the discharge process. ETHICS AND DISSEMINATION: Ethics approval for the study was obtained from the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committees. Results of the study would be released as a report submitted to the Health and Medical Research Fund of Food and Health Bureau of the Hong Kong Government. The result would also be published in international peer-reviewed medical journals and presented in conferences. TRIAL REGISTRATION NUMBER: ChiCTR2000034382.
