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

The American Association of Oral and Maxillofacial Surgeons (AAOMS) is currently conducting an important study designed to collect outcome data and develop benchmark statistics for anesthesia and third molar extraction. The primary goal of the proposed anesthesia and third molar studies is 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) Team Anesthesia Model (TAM). 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 is 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.

Random Sample Framework for Selection of Study Participants

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). Selected OMS are currently being contacted by AAOMS to confirm their participation in the study.

If you are Selected to Participate in the Study

It is very important that OMS who are selected in the sample of 300 participate in the study. It is randomization that makes randomized clinical trials the gold standard of clinical research and, similarly, if AAOMS members were allowed to volunteer for the benchmarking study, we could not be sure that the resulting sample would be representative of the population of private practice OMS. Participation in this study will require a serious commitment of time and resources, but the specialty is at a challenging moment in our history. Increasing questions from various sectors on the OMS anesthesia team model and the management of third molars underscore the need for objective data on safety and effectiveness, and patient satisfaction of these procedures in the OMS office. Therefore, we ask that if selected to participate in the study, you wholeheartedly commitment to the project.

The study data collection form was developed by practicing OMSs and the information participants are asked to provide is typically included in the patient record maintained in an OMS office. Participants will administer a brief anesthesia satisfaction survey to their patients and include the survey information in the data they input on-line. The secure, HIPPA compliant, on-line data collection instrument is maintained by Outcome. Each participant will enter data for eligible patients treated during their assigned month. Eligible patients are those who received anesthesia (local and/or sedation through general anesthesia). Data from participants who do not fully participate in the study were not utilized in the tabulation of the benchmark statistics. Study participants are allowed to enter data throughout the entire study period for purposes of documenting their own practice, however, the benchmark tabulations only use data collected in their assigned month. Data entry should take 5-15 minutes per eligible patient. All data collected are confidential. Only de-identified, aggregated data will be published. Participants will receive 15 CME credits and a report that compares their data to the aggregate data. Study Participants will also be able to download the data you entered for your own use.

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.
