美國加州大學洛杉磯分校Yusuke Tsugawa團隊研究了在外科醫師生日當天接受手術的患者的死亡率。2020年12月10日,該研究發表在《英國醫學雜誌》上。
為了確定外科醫生在生日那天進行的手術與一年中其他日子相比,術後患者的死亡率是否有所不同,研究組在美國急診和重症監護醫院進行了一項回顧性觀察研究。研究組招募了65-99歲、100%有償付費醫療保險受益人,他們在2011-14年度接受了17種常見的緊急外科手術之一。主要結局為患者術後30天的死亡率。
研究組共分析了47489名外科醫生施行的980876例手術。其中2064例(0.2%)手術是在外科醫生的生日當天進行的。在外科醫生生日那天接受手術的患者與其他日子接受手術的患者臨床特徵(包括疾病的嚴重程度)相差不大。
在手術外科醫生的生日那天接受手術的患者未經校正的30天總死亡率為7.0%,而在其他日子手術的患者則為5.6%。在校正了患者特徵和外科醫生的固定效應(有效比較同一位外科醫生在不同日期進行手術的患者的結局)後,在外科醫生生日那天進行手術的患者的死亡率顯著高於在其他日子進行手術的患者,校正後的死亡率分別為6.9%和5.6%。事件研究分析了手術日的病人死亡率與外科醫生生日之間的相關性,發現了相似結局。
研究結果表明,對於接受常規緊急手術的醫保受益人,在外科醫生生日那天接受手術的患者的死亡風險顯著高於其他日子接受手術的患者。

Abstract:
Objective To determine whether patient mortality after surgery differs between surgeries performed on surgeons』 birthdays compared with other days of the year.
Design Retrospective observational study.
Setting US acute care and critical access hospitals.
Participants 100% fee-for-service Medicare beneficiaries aged 65 to 99 years who underwent one of 17 common emergency surgical procedures in 2011-14.
Main outcome measures Patient postoperative 30 day mortality, defined as death within 30 days after surgery, with adjustment for patient characteristics and surgeon fixed effects.
Results 980876 procedures performed by 47489 surgeons were analyzed. 2064 (0.2%) of the procedures were performed on surgeons』 birthdays. Patient characteristics, including severity of illness, were similar between patients who underwent surgery on a surgeon’s birthday and those who underwent surgery on other days. The overall unadjusted 30 day mortality on the operating surgeon’s birthday was 7.0% (145/2064) and that on other days was 5.6% (54824/978812). After adjusting for patient characteristics and surgeon fixed effects (effectively comparing outcomes of patients treated by the same surgeon on different days), patients who underwent surgery on a surgeon’s birthday exhibited higher mortality compared with patients who underwent surgery on other days (adjusted mortality rate, 6.9% v 5.6%; adjusted difference 1.3%, 95% confidence interval 0.1% to 2.5%; P=0.03). Event study analysis of patient mortality by day of surgery relative to a surgeon’s birthday found similar results.
Conclusions Among Medicare beneficiaries who underwent common emergency surgeries, those who received surgery on the surgeon’s birthday experienced higher mortality compared with patients who underwent surgery on other days. These findings suggest that surgeons might be distracted by life events that are not directly related to work.
