Abstract
Workforce management in anesthesia services is crucial for service quality. However, the data associated with this are lacking. Therefore, this study was done to analyze workforce and workload and to compare differences among hospital clusters in Thailand. We conducted a cross-sectional study in multilevel hospitals that were classified by location, the population cared for, and the categorization of physicians. Stratified randomization from all health service regions across Thailand was done. The profile of hospitals, number of anesthesia staffs, their capabilities, and ratio of anesthesia personnel to the service provided during the 5 workdays and 1 weekend period were analyzed. A total of 18 hospitals, ranging from secondary to super-tertiary referral centers, were included in the study. The mean number of personnel ranged from 2.0 ± 1.2 to 12.0 ± 0 for anesthesiologists and 7.5 ± 2.9 to 42.3 ± 19.3 for nurse anesthetists from each hospital cluster, which vary in terms of capabilities and the number of staff. The average number of anesthesia service units was 9.1 ± 4.2 to 31.9 ± 16.4, while the number of operating theaters was 6.9 ± 2.2 to 22.7 ± 8.3. However, the ratio of anesthesia personnel to one anesthesia service unit and the ratio of these personnel to an operating theater were not significantly different among the participating hospitals, with a mean of 0.94 ± 0.45 and 1.34 ± 0.38, respectively. The overall number of anesthesia service units was above the designated operating theater capacity, while the ratio of anesthesiologists was 0.8-1.3 and nurse anesthetists was 2.4-6.5 per 100,000 people on an average, with a disproportionate responsibility ratio of anesthesia personnel to anesthesia service units during that time.
