Abstract

Surgeons and medical staff attend academic meetings several times a year. However, there is insufficient evidence on the influence of the “meeting effect” on traumatic brain injury (TBI) treatments and outcomes. Using the Japan Trauma Data Bank, we analyzed the data of TBI patients admitted to the hospital from 2004 to 2018 during the national academic meeting days of the Japanese Association for Acute Medicine, the Japanese Society of Intensive Care Medicine, the Japanese Association for the surgery of trauma, the Japan Society of Neurotraumatology and the Japan Neurosurgical Society. The data of these patients were compared with those of TBI patients admitted 1 week before and after the meetings. The primary outcome was in-hospital death. We included 7320 patients in our analyses, with 5139 and 2181 patients admitted during the non-meeting and meeting days, respectively; their in-hospital mortality rates were 15.7% and 14.5%, respectively. No significant differences in in-hospital mortality were found (adjusted odds ratio, 0.93; 95% confidence interval, 0.78–1.11). In addition, there were no significant differences in in-hospital mortality during the meeting and non-meeting days by the type of national meeting. In Japan, it is acceptable for medical professionals involved in TBI treatments to attend national academic meetings without impacting the outcomes of TBI patients.

Highlights

Surgeons and medical staff attend academic meetings several times a year
Despite the growing evidence supporting the value of specialized teams and intensive care unit (ICU) for complex patient populations, such as traumatic brain injury (TBI) and trauma patients, the relationship between post-TBI survival and attendance of medical staff in national academic meetings related to trauma or ICU has been insufficiently examined
We included TBI cases registered in the database from January 2004 to December 2018 and those transported to Japanese Trauma Data Bank (JTDB)-participating hospitals

Summary

Introduction

Surgeons and medical staff attend academic meetings several times a year. there is insufficient evidence on the influence of the “meeting effect” on traumatic brain injury (TBI) treatments and outcomes. Using the Japan Trauma Data Bank, we analyzed the data of TBI patients admitted to the hospital from 2004 to 2018 during the national academic meeting days of the Japanese Association for Acute Medicine, the Japanese Society of Intensive Care Medicine, the Japanese Association for the surgery of trauma, the Japan Society of Neurotraumatology and the Japan Neurosurgical Society. Implementing dedicated trauma care units and involving trauma-specific physician assistants seem to be b eneficial[5] In this sense, the composition of hospital staff during national meeting days or off-days is thought to be associated with increased mortality risk for critically ill patients and those requiring emergent surgical interventions[6,7,8,9]. Using this database, we evaluated differences in in-hospital survival after TBI during national meeting and non-meeting days in Japan. We hypothesized that there would be increased TBI-associated mortality during the national meeting days because many ER physicians and neurosurgeons attend these meetings
