Enhanced hospital-wide communication and interaction by team training to improve patient safety.

Communication errors are the most important cause of adverse events in healthcare. The current study aimed to improve hospital-wide employee teamwork and reduce adverse medical events for patients arising from miscommunication. In our hospital, when patient safety incidents and accidents occur, staff from various occupations submit incident reports to the Department of Patient Safety via an electronic reporting system; over 11,000 cases are reported each year. We surveyed the incident reports submitted in our institution from 2016 to 2018. All incidents related to miscommunication were identified, and relevant information was collected from the original electronic incident reports. Incident severity classification is commonly divided into near-miss or adverse events. We extracted only the required incident information items for this study, and processed information concerning individuals (e.g., reporters and target patients) anonymously. This study was approved by the Institutional Review Board of the study hospital. The authors declare no conflicts of interest associated with this study. Team training for all employees reduced adverse events for patients. The coefficient of determination (R squared value) was -0.32. This suggests our approach may be slightly but significantly effective for developing the fundamental strengths of the medical team. Quality improvement is continuous, and seamless efforts to improve the effectiveness of medical teams at our hospital will continue.
