Objective:To explore the experience and feelings of hip and knee replacement patients participating in the enhanced recovery after surgery (ERAS) model during hospitalization, so as to provide a reference for the improvement of ERAS perioperative and continuous nursing plans.Methods:From August to November 2019, purpose sampling was used to select 15 patients undergoing hip and knee replacement who were admitted to the Department of Joint Surgery of a ClassⅢ Grade A hospital in Guangdong Province for the semi-structured interview. Colaizzi's 7-step analysis method on phenomenology was used to analyze, summarize and refine the themes of the collected interview data.Results:The experience and feelings of joint replacement patients participating in the ERAS model during hospitalization can be summarized into 4 themes, namely uncertainty of information, being worried about the treatment effect, insecurity of early discharge, the contradiction between the desire to return and lack of confidence.Conclusions:Patients participating in ERAS had a short hospital stay after hip and knee replacement, and could not fully digest the information provided by the medical and nursing staff. Patients were also worried that they would not be able to cope after being discharged from the hospital. Clinical medical and nursing staff should fully evaluate the patient's readiness for discharge, provide personalized guidance, perfect out-of-hospital continuous nursing services and improve the patient's experience of early discharge.
