Abstract

　　To investigate the relationship between hospital length of stay and initial clinical information in patients with rib fractures due to blunt chest trauma.

　　This study included 92 eligible patients. We analyzed hospital length of stay (HLS) by multiple linear regression analysis. The gender, age, heart rate (HR), systolic blood pressure (SBP), and number of rib fractures (FxNo) were assumed as independent variables. We also assessed the following : presence of pneumo-hemothoraces, chest drainage tube requirements, and epidural anesthesia or intercostal block requirements.

　　In conclusion, HLS was estimated using the following formula ; HLS=4.9+0,9×FxNo±15.6 (days). When patients were older than 60, the estimated length of stay increased by 3.3 days. Also, when patients required chest tube drainage, the estimated length of stay increased by 3.6 days.

　　Using this formula, we are able to estimate the length of hospital stay at the initial clinical presentation. We also suggest the importance of prevention of pneumonia to avoid extension of hospital stay.
