Background: This study was conducted to provide an overview of anesthesia services in Taiwan from 2001 to 2010.
Methods: A retrospective population-based analysis was performed using data from Taiwan's National Health Insurance Research Database for the period 2001 to 2010. The results were stratified by patient sex, patient age, anesthesia type, and hospital setting. Categorical data are presented as totals and percentages. Linear regression was performed to analyze the anesthesia trends.
Results: The annual use of anesthesia increased continually from 964,440 instances in 2001 to 1,073,160 in 2010, totaling 10,076,600 cases with a total cost of 25.4 billion USD. The overwhelming majority (83.9%) of anesthesia cases was for anesthesia in an inpatient setting; general anesthesia accounted for 73.8% of anesthesia cases, and female patients outnumbered male patients (52.4% vs 47.6%). The average number of anesthesia cases was 44.2 per thousand of the population annually, but this percentage was much higher in elderly people (100.9 cases per thousand people annually). The annual number of anesthesia cases per thousand of the population increased from 104.4 in 2001 to 113.0 in 2010 in the oldest group (>80 years). By contrast, a considerable decline in use of anesthesia was discovered over the study period among those aged younger than 18 years.
Conclusion: The use of anesthesia services in Taiwan has increased over the years. The relationships of age with anesthesia volume and cost were found to follow an inverse U-shaped pattern. Elderly people used anesthesia services more frequently. The planning of geriatric anesthesia services deserves attention, especially in continually aging societies such as Taiwan.
