Postoperative wound infections detected during hospitalization and after discharge in a community hospital.
Postoperative wound infections were evaluated in 1271 patients who had 1389 surgical procedures. There were 49 postoperative wound infections identified, of which 26 (53%) were discovered after discharge. Wound infections varied from 2.5% for clean wounds up to 13.3% for dirty wounds. Among the specialties, the infection rate ranged from no infection for otolaryngologists and urologists to 8.6% for general surgeons. With routine hospital surveillance, the overall infection rate was 1.8% or 2.2%, including readmissions for infection, but less than the actual rate of 3.8%. Persons who had three procedures had no infection rate of 27.3%; for two procedures, 8.1%; and for one procedure, 3.2%. Most postoperative wound infections detected after discharge were based on clinical grounds and not positive cultures. Rehospitalization was required for seven patients because of infection. This study demonstrates that postoperative wound infection surveillance must be continued after discharge.
