Background and objective: The increasing workload in anesthesiology together with the shortage of anesthetists has led to worldwide concern within the specialty. In 2003, the Catalan Society of Anesthesiology, Critical Care and Pain Therapy undertook the ANESCAT survey to determine the anesthesia practice workload in Catalonia, Spain.
Patients and method: A set of 3 questionnaires was used to quantify anesthesia practice and resources. A sample size of 12,228 events was estimated to be necessary to be representative of the number of anesthetic procedures carried out in Catalonia annually. A prospective, cross-sectional survey was carried out on 14 randomly chosen days in 2003. Each hospital designated a coordinator responsible for ensuring that a questionnaire was filled in for each anesthetic procedure, to provide information about patient characteristics, anesthetic technique, and the intervention for which anesthesia was needed.
Results: All 131 public and private hospitals in which anesthetic procedures were carried out participated. The geographic distribution was as follows: Barcelona city, 54 (41.2%); rest of the province of Barcelona, 39 (29.8%); Tarragona, 15 (11.5%); Girona, 14 (10.7%), and Lleida, 9 (6.9%). A total of 23,136 questionnaires about anesthesia procedures were received; the number of questionnaires returned on the selected workdays varied by 1.85% and the percentage of incomplete returns was less than 5%. The number of individual anesthetists returning questionnaires for processing was 765.
Conclusions: This large-scale study was possible thanks to a simple design and the strong motivation of a community of anesthesiologists. The results have provided an accurate picture of anesthesia practice within a specific geographical area. Such studies are necessary for introducing organizational changes and applying for additional resources.
