The US residency application, interview, and match processes are costly and time-intensive. We sought to quantify the importance of an applicant being from the same-state as a residency program in terms of how this impacted the number of interviews needed to match.
We examined data from interview scheduling software used by 32 programs located in 31 US states and 1300 applicants for the US anesthesiology recruitment cycles from 2015 to 2018. Interviewee data (distance from program, region, numbers of interviews, and program at which interview occurred) were analyzed to quantify the effect of the interviewee being from the same state as the residency program on the odds of matching to that program. Other variables of interest (medical school, current address, US Medical Licensing Exam [USMLE] Step 1 and 2 clinical knowledge [CK] scores, Alpha Omega Alpha [AOA] status, medical school ranking) were also examined as controls. Confidence intervals (CI) were calculated for the ratios of odds ratios.
An interviewee living in the same state as the interviewing program could have 5.42 fewer total interviews (97.5% CI, 3.02-7.81) while having the same odds of matching. The same state effect had an equivalent value as an approximately 4.14 USMLE points-difference from the program's mean (97.5% CI was 2.34-5.94 USMLE points). Addition of whether the interviewee belonged to an affiliated medical school did not significantly improve the model; same-state remained significant (P < .0001) while affiliated medical school was not (P = .40).
Our analysis of anesthesiology residency recruitment using previously unstudied interview data shows that same-state locality is a viable predictor of residency matching and should be strongly considered when evaluating whether to interview an applicant.
美国住院医师申请、面试和匹配过程既昂贵又耗时。我们试图量化申请人与住院医师项目所在州相同的重要性，以及这对匹配所需面试次数的影响。
我们检查了 32 个项目使用的面试安排软件的数据，这些项目位于 31 个美国州和 1300 名参加美国麻醉学招聘周期的申请人，时间为 2015 年至 2018 年。分析了受访者数据（与项目的距离、地区、面试次数以及面试地点的项目），以量化受访者与住院医师项目所在州相同对匹配该项目的几率的影响。还检查了其他感兴趣的变量（医学院、当前地址、美国医师执照考试[USMLE]第 1 步和第 2 步临床知识[CK]分数、阿尔法欧米茄阿尔法[AOA]地位、医学院排名）作为对照。计算了比值比的置信区间（CI）。
住在与面试项目相同州的受访者可以减少 5.42 次总面试（97.5%CI，3.02-7.81），同时具有相同的匹配几率。相同州的效果与程序平均值相差约 4.14 USMLE 点（97.5%CI 为 2.34-5.94 USMLE 点）相当。是否受访者属于附属医学院并没有显著改善模型；相同州仍然具有显著性（P <.0001），而附属医学院则没有（P =.40）。
我们使用以前未研究过的面试数据对麻醉学住院医师招聘进行的分析表明，州内位置是住院医师匹配的可行预测指标，在评估是否面试申请人时应予以充分考虑。
