The Sociocultural Effects on Orthopedic Surgeries in Taiwan

Various sociocultural factors affect healthcare-seeking behaviors. In Taiwanese society, superstitions and lunar festivals play important roles in people's lives. We investigated the impact of "Ghost Month" (the 7th lunar month) and Chinese New Year (the 12th lunar month and the 1st lunar month of the following year) on the number of elective surgeries and emergent surgeries in Taiwan. The number of total knee replacement (TKR) surgeries and proximal femur fracture (PFF) surgeries in each lunar month from 2000 to 2011 were extracted from the Taiwan National Health Insurance Database, a computerized and population-based database. Patients were then sorted by location of residence or gender. The average number of TKR surgeries performed was significantly lower during the 1st, 7th, and 12th lunar months in urban areas, whereas in rural areas this trend was only evident in the 7th and 12th lunar months. There was however, no significant difference in the average number of PFF surgeries in each lunar month except for an increase seen in the 1st lunar month in rural patients (p<0.05). When sorted by gender, the average number of TKR surgeries was significantly decreased in the 7th and 12th lunar months in male patients, and decreased in the 1st, 7th, and 12th lunar months in female patients. In contrast, there was no difference in the average numbers of PFF surgeries in the 7th and 12th lunar months either in male or female patients. We proposed that the timing of elective surgeries such as TKR might be influenced by Ghost Month and Chinese New Year; however, emergent PFF surgeries were not significantly influenced by sociocultural beliefs and taboos in Taiwan.
