Abstract

Introduction: There is increasing evidence that peripheral nerve block (PNB) anesthesia is associated with a favorable recovery profile, reduced cost and high patient satisfaction. For these reasons, there has been a recent resurgence of interest in PNB. Since ASRA has become a leader in the education of regional anesthesia, we tested the hypothesis that anesthesiologists who are members of ASRA are more likely to employ PNB than anesthesiologists who are not members of the society. Methods: 683 randomly selected members of ASA and ASRA were mailed a questionnaire regarding the use of (PNB) and neuraxial anesthesia in their practices. Only ASA members who were not also members of ASRA were included in the analysis. Results: A total of 413 attending anesthesiologists (210 ASA members and 203 ASRA members) completed the survey. This number (a 60.5% response rate) satisfied the sample size that had been estimated to contain results within a 5% margin of error. Most respondents (296 or 71.7%) were between 30 and 49 years of age and approximately half had been in practice more than 10 years. One hundred thirty-six (36%) practiced in teaching hospitals, 222 (58.7%) in non-teaching institutions, and 42 (11.1%) in ambulatory care centers. Age, gender, practice setting, and years in practice did not differ between members of ASA and ASRA. Members of ASRA were more likely to perform regional anesthesia. While 42.7% of ASRA members devoted more than 30% of their annual practice to regional anesthesia, only 24.9% of ASA members devoted a similar amount of their practice to regional anesthesia (pO.OOl). ASRA members performed more PNBs than their ASA counterparts. While 35% of ASRA members performed more than 10 blocks per month, far fewer ASA members (21.4%) performed more than 10 blocks per month (p<0.003). The only noticeable exception was IV regional anesthesia, which was performed slightly more often by ASA members than by ASRA members (88% vs. 83.3%, respectively). Discussion: Members of ASRA practice significantly more regional anesthesia and perform more PNBs than members of ASA. Differences were greatest in the lower extremity blocks. These results emphasize the role of ASRA members in fostering regional anesthesia techniques in clinical practice and its teaching to students of anesthesia. The results might also suggest that ASRA has been successful in recruiting members who are interested in regional anesthesia.
