ABSTRACT

Objective: To compare the surgical wound infection rate obtained in 1998 with that of 1989, first year of the surveillance program.
Setting: Second level health care hospital.
Methods: Prospective, observational, descriptive, transversal study of 850 surgical wounds from November 1st, 1997 to November 1st, 1998 and comparison with the corresponding data obtained in 1989.
Results: From the 850 wounds, 16 were infected for an overall infection rate of 1.8%; 481 (56.5%) were clean, 119 (14%) were clean but contaminated, 182 (21.4%) were contaminated and 68 (8%) were dirty, yielding infections rates of 1.03, 1.68, 2.7, and 5.8% respectively. In 1989, 975 wounds were registered with an overall infection rate of 2.9%; 725 (74.35%) were clean, 62 (6.3%) were clean but contaminated, 119 (12.2%) were contaminated, and 69 (7.07%) were dirty, with infection rates of 2.6, 0, 2.5, and 10.1%, respectively.
Conclusion: The difference in infection rates was not statistically significant and these were within acceptable levels. However, the difference in infection rates in dirty wounds is important and might reflect the use of subcutaneous catheters for suction-irrigation with antibiotics in 1998. Surveillance programs are useful to maintain infection rates within reasonable limits.
