Benchmark statistics are used in quality assurance/quality improvement processes. The purposes of the present report are to 1) review the rationale for a new specialty-specific benchmark study, 2) summarize the methods to create a practice-based research collaborative (P-BRC) designed for collecting data to create benchmarks, and 3) describe the characteristics of the P-BRC surgeon participants.
The study was designed as a prospective cohort study. We created a P-BRC composed of randomly selected American Association of Oral and Maxillofacial Surgeons (AAOMS) members in private practice in the United States, who agreed to enroll patients scheduled to receive anesthesia of any type in the office-based ambulatory setting. The study variables included clinician demographics and their P-BRC status, grouped as 1) invited, active participants, 2) invited, inactive participants, and 3) uninvited AAOMS members. The P-BRC participants collected data for dozens of variables from their patients related to anesthesia. If the procedure was third molar (M3) surgery, additional M3 procedure-specific data were collected. Data analyses were composed of computing descriptive and bivariate statistics. Preliminary sample size estimates suggested that the P-BRC should include 300 surgeons to produce estimates with a ±5% error.
During the 1-year study interval, 642 surgeons (11.8%) were invited to join the P-BRC from a population of 5,455 eligible AAOMS members. The 124 active participants in the P-BRC contributed 6,344 subjects to the anesthesia data set and 2,978 subjects who had had 9,207 M3s removed to the M3 data set. The active participants in the P-BRC were younger and more likely to be board-certified than were the inactive participants (P < .05). Details of the anesthesia and M3 variables will follow in future reports.
Despite vigorous efforts, we did not achieve our stated goal of creating a P-BRC composed of a random sample of 300 AAOMS members. With the current P-BRC sample, variables with very high (>93%) or very low (<7%) frequency estimates will produce estimates with the desired range of ±5% error. The P-BRC includes a sample of self-selected, not random, participants and is well-characterized in terms of age, gender, board-certification status, academic degrees, and geographic distribution.
基准统计用于质量保证/质量改进过程。本报告的目的是：1）回顾一项新的特定专业基准研究的基本原理；2）总结创建一个基于实践的研究协作组（P-BRC）的方法，该协作组旨在收集数据以创建基准；3）描述P-BRC外科医生参与者的特征。
本研究设计为前瞻性队列研究。我们创建了一个P-BRC，其成员由在美国私人执业的美国口腔颌面外科医师协会（AAOMS）成员中随机选取，这些成员同意纳入计划在门诊非住院环境中接受任何类型麻醉的患者。研究变量包括临床医生的人口统计学信息及其在P-BRC中的状态，分为1）受邀的活跃参与者；2）受邀的非活跃参与者；3）未受邀的AAOMS成员。P-BRC参与者从其患者中收集了数十个与麻醉相关的变量数据。如果手术是第三磨牙（M3）手术，则收集额外的特定于M3手术的数据。数据分析包括计算描述性统计和双变量统计。初步样本量估计表明，P-BRC应包括300名外科医生，以产生误差在±5%范围内的估计值。
在为期1年的研究期间，从5455名符合条件的AAOMS成员中邀请了642名外科医生（11.8%）加入P-BRC。P-BRC中的124名活跃参与者为麻醉数据集贡献了6344名受试者，为M3数据集贡献了2978名拔除了9207颗M3的受试者。P-BRC中的活跃参与者比非活跃参与者更年轻，且更有可能获得委员会认证（P <.05）。麻醉和M3变量的详细信息将在未来报告中公布。
尽管付出了巨大努力，但我们并未实现创建一个由3个随机样本的AAOMS成员组成的P-BRC的既定目标。对于当前的P-BRC样本，频率估计值非常高（>93%）或非常低（<7%）的变量将产生误差在所需的±5%范围内的估计值。P-BRC包括一个自我选择而非随机选择的参与者样本，并且在年龄、性别、委员会认证状态、学术学位和地理分布方面具有良好的特征。
