The Southeast and East Asian Post-Operative Delirium (SEAPOD) Study

The specific aim of the study will be to investigate the incidences and risk factors for postoperative delirium (POD) after hip fracture surgery in elderly patients aged ≥ 65 years in five different Southeast and East Asian countries. The secondary objectives are outlined below: 1. To investigate factors in the hospital environments, such as noise levels, ambient lighting, nursing ratios, ward bedding and climate control, that contribute to similarities and/or differences in POD occurrences in different countries and health systems 2. To investigate patient factors, such as disease burden, mental health, education levels, and socioeconomic factors, that contribute to similarities and/or differences in POD occurrences in different countries and health systems 3. To quantify the direct and indirect costs, as well as resource utilization, resulting from the development of POD in each country
