Introduction: Pneumonia is a known complication following rib fractures. This study was undertaken to identify clinical and demographic factors associated with the development of pneumonia among trauma patients with rib fractures. Methods: This retrospective study examined trauma patients with one or more rib fractures, who were admitted for inpatient management during the time period 2012 through 2017. Variables studied included age, gender, injury severity score (ISS), mechanism of injury, smoking status, alcohol use, administration of influenza and pneumococcal vaccine, number and side of rib fracture(s), pulmonary contusion, pneumothorax, flail chest, spirometer use, blood transfusion, and intravenous fluid administration. Results: Among 78 cases and 74 controls (matched for age and ISS), patients who developed pneumonia were more likely to be male, have higher number of rib fractures, alcohol consumption of 1–5 drinks per day, and a higher initial volume of intravenous fluids during first 24 h. Patients with pneumonia were more likely to be treated with incentive spirometry. There were no difference in age, ISS, smoking status, side of rib fractures, pulmonary contusion, pneumothorax, flail chest, influenza vaccination, pneumonia vaccination, or mechanism of injury between the two groups. Conclusion: Risk factors for the development of pneumonia following rib fractures include male gender, higher number of rib fractures, alcohol consumption, and higher rates of intravenous fluid administration during the initial 24 h following trauma.
