The incidence of community-acquired infections (CAs) and their relationship to the incidence of nosocomial infections (NI), to our knowledge, is unknown in elderly trauma patients. We prospectively collected data on 380 patients ≥65 years of age who were admitted >48 h to our trauma center over a 2-year period. One hundred seventy-seven patients (47%) developed an infection. A total of 147 (39%) patients were diagnosed with an NI, and 67 (18%) were diagnosed with a CA. Of the 67 patients with CA, 37 (55%) went on to develop an NI. Patients with the combination of CA and NI had the greatest mean ICU (28.6 days) and hospital length of stay (38.2 days). Mortality was increased significantly in patients with the combination of CA and NI (27%). Respiratory and genitourinary infections were the most common CA. Patients with respiratory CAs accounted for the greatest proportion of NIs. Thus, community-acquired and nosocomial infections significantly increase morbidity and mortality in elderly patients post-injury. Patients who present with a CA are at increased risk of acquiring an NI, which is associated with the most significant increase in length of stay and mortality.
