The state of anesthesia in South Korea: a national survey of the status of anesthetic service activity in 2014–2016

BACKGROUND: Because the quality of anesthesia affects the surgical outcome, the aim of this study was to investigate the current status of anesthetic services performed by anesthesiologists and non-anesthesiologists in South Korea from 2014 to 2016 and to compare the results with data from 2011 to 2013. METHODS: The claimed anesthesia services at medical institutions with employed anesthesiologists and the claims for an invitation fee for an anesthesiologist at medical institutions without employed anesthesiologists were regarded as anesthetic services performed by an anesthesiologist. From 2014 to 2016, the employment of anesthesiologists according to the type of medical institution, the status of anesthetic services according to the presence or absence of employed anesthesiologists, and status of anesthetic services at medical institutions without employed anesthesiologists were analyzed. RESULTS: The proportion of medical institutions that employed anesthesiologists slightly increased from 27.8% in 2014 to 28.8% in 2016. General anesthesia was more concentrated at higher medical institutions, and most anesthesias were performed by an anesthesiologist. The proportion of spinal anesthesia, epidural anesthesia, and brachial plexus performed by non-anesthesiologists was 11%, 15%, and 16.5%, respectively. Intravenous anesthesia performed by non-anesthesiologists was 58% and has increased compared to the past. CONCLUSIONS: The employment of anesthesiologists has increased with time, and general anesthesiology was mostly performed by anesthesiologists. However, since the proportion of anesthetic services performed by non-anesthesiologists in regional anesthesia and intravenous anesthesia was maintained high, it is necessary to find ways to expand the safety of anesthetic services.
