AAOMS Outcomes Assessment Project: AAOMS Anesthesia and Third Molar Extraction Outcomes Study

AAOMS thanks the OMS who participated in the AAOMS Anesthesia and Third Molar Extraction Outcomes Study. Only through your efforts were we able to collect important practice data on the OMS specialty. OMS wishing to participate in future AAOMS studies should consider joining the AAOMS Practice Based Research Network.

The American Association of Oral and Maxillofacial Surgeons (AAOMS) conducted a study designed to collect outcome data and develop benchmark statistics for anesthesia and third molar extraction. The study period was 12 months and began on June 1, 2011 and ended May 31, 2012.The primary goal of the proposed anesthesia and third molar studies was to establish numerical targets or benchmarks for various clinical outcomes in the delivery of anesthesia and third molar services using the Oral and Maxillofacial Surgery (OMS) Anesthesia Team Model. These benchmarks could serve as guides to document patient quality and safety efforts in the delivery of oral and maxillofacial surgical services in the office-based ambulatory setting. A secondary goal of this project was to identify a set composed of one or more variables associated with a clinical outcome of interest, e.g. surgical site infection or length of disability, that may be modified by clinicians to improve outcomes.

In order to develop benchmark statistics that are unbiased and representative of all private practice oral and maxillofacial surgeons a random sample framework was employed. Three hundred OMS were randomly selected from a list of all active private practice OMS members. Full and part-time faculty members and members located in Puerto Rico, Guam, and the Virgin Islands were excluded. The sample was stratified by census region prior to selection. The percentage of the population of OMS located in each region was 23.7% Northeast, 20.6% Midwest, 34.7% South, and 21.6% West. Based on this distribution, the initial sample of 300 contained 69 OMS from the Northeast, 62 OMS from the Midwest, 104 OMS from the South, and 65 OMS from the West. Each selected OMS was randomly assigned to participate in a given month during the 12 month study period (a maximum of 25 participants per month).

The study data collection form was developed by practicing OMSs and the information participants were asked to provide is typically included in the patient record maintained in an OMS office. Participants administered a brief anesthesia satisfaction survey to their patients and included the survey information in the data they inputted into our on-line data collection system. The secure, HIPPA compliant, on-line data collection instrument was maintained by Quintiles Outcome. Each participant entered data for eligible patients treated during an assigned month. Eligible patients were those who received anesthesia (local and/or sedation through general anesthesia).

The goal of the study was to enroll 300 participants with a minimum goal of 150. In an effort to meet the study recruitment goals, invitations were ultimately extended to 643 OMS and 124 OMS (19.2%) participated in the study. Of the 124 OMS who entered data, 88 were in our initial sample of 300.  Four datasets have been assembled from the data collected. Data from participants who did not fully participate in the study were not utilized in the tabulation of study benchmark statistics. Therefore the final anesthesia database includes data from 95 OMS who entered 5,929 anesthesia cases. The third molar results are from 105 OMs who completed the third molar data collection forms for 2,954 patients and 9,123 extracted third molars. Only de-identified, aggregated data will be published from this study. Results from the study were initially presented at the AAOMS 2012 Annual Meeting. Data will be published in future issues of the Journal of Oral and Maxillofacial Surgery.

Important Documents

The on-line data collection forms are designed for ease of use by the study participant. The pdf versions of the forms provide prospective participants with an opportunity to review the information that is being collected but do not necessarily demonstrate the convenience of the on-line form. The study help manual and a list of frequently asked questions are also provided.
