Objective:To explore the discharge readiness and influencing factors of patients with multimorbidity, and to formulate corresponding strategies to guide clinical work.Methods:In a cross-sectional study, 183 patients were surveyed by convenience sample method for Department of General Practice, the Third Hospital of Peking University February in to December 2022. Multiple linear regression was used to analyze the factors affecting discharge readiness.Results:All 183 coexisting patients, 95 males, 88 females, mean age (67.34 ± 10.36) years old. Mean discharge readiness was (109.83 ± 18.40). 54.9% of the factors for patients with multiple chronic diseases came from the perception of self-care disorder, hospitalization, stay, and preparation for discharge ( R2=0.549, P<0.05). Conclusions:The discharge readiness of patients with multiple chronic diseases in general medicine is at a high level, and clinical nursing staff should give early intervention to the patients who perceive self-care barriers, need to stay with them, have multiple hospitalization, and are not ready for discharge, so as to ensure that the patients are in a good state of discharge readiness.
