Comparison of 30-day planned and unplanned readmissions to huge hospital in China

Abstract

Purpose: To compare and analyze the clinical characteristics and influencing factors of planned and unplanned readmissions within 30 days to provide a basis for the quality of care management.Methods: We searched for inpatients at West China Hospital from January 1, 2015, to December 31, 2020. Patients were divided into unplanned readmission and planned readmission groups according to 30-day readmission status. Patient demographics and related information were collected for each patient.Results: We identified 1,242,496 hospitalized patients, including 74,494 (6.0%) 30-day planned readmissions and 9,895 (0.8%) unplanned readmissions. There were statistically significant differences between planned and unplanned readmissions in terms of patient gender, marital status, age, length of initial stay, the time between discharge, stay in ICU, surgery, and health insurance.Conclusion: Accurate information on 30-day planned and unplanned readmissions facilitates effective planning of healthcare resource allocation. Identify risk factors for 30-day unplanned readmission and develop interventions to reduce readmission rates.
