Abstract
Fever in the postoperative period frequently results in a battery of diagnostic tests in search of an etiology. We sought to evaluate the incidence and utility of extensive postoperative fever evaluations in a teaching hospital setting. Prospective observational study of all adult patients undergoing in-patient general surgical procedures during a 13-mo period. Patients experiencing an early postoperative fever (>100.4° F in the first 72 h) had data collected on their evaluation, the yield of the diagnostic studies, and whether an infectious diagnosis was made. Of 1032 surgical procedures, 245 (23.7%) patients experienced an early postoperative fever. One hundred patients (9.7%) underwent documented fever evaluation. Thirty-five (35%) had blood cultures with no positive results among elective surgery patients. Forty-six patients (46%) had urine cultures sent, of which four infections were diagnosed (8.9%). Fifty chest radiographs were performed, but the diagnosis of pneumonia was made by only three (6.0%). Ultimately, 18 febrile patients (18%) were diagnosed with an infectious source, in nine of these patients the physical exam and clinical picture accurately diagnosed the infection without need for further testing.
