Basic objectives -Others
To examine international similarities and differences in postoperative delirium (POD) incidence, this study aims to: (1) investigate hospital environmental factors such as noise, lighting, nursing ratios, bedding, and climate control; (2) explore patient-related factors including disease burden, mental health, education, and socioeconomic status; and (3) quantify both direct and indirect costs and healthcare resource utilization associated with POD in different countries and health systems.

This observational study will be conducted at Tokyo Women's Medical University Hospital as part of the SEAPOD Study, an international collaborative study on postoperative delirium in Southeast and East Asia. The population will consist of patients aged 65 years or older who underwent hip fracture surgery at Tokyo Women's Medical University Hospital, and we will conduct an observational study of their preoperative, intraoperative, and postoperative status. The main purpose of this study is to identify the incidence of postoperative delirium and risk factors by comparing the results obtained at Tokyo Women's Medical University Hospital with those of other institutions in Southeast and East Asia.
