OBJECTIVE: We reviewed the records of 126 patients who underwent PEG insertion during a 36-month period to determine the etiology of an observed increase in PEG-related infections.
METHODS: Charts were reviewed to determine predictive factors of infection, the occurrence of infection, and culture results of infected sites. Insertion was performed in all cases using a standard sterile, pull-through technique. Infections were defined as having at least two of the following conditions: peristomal erythema, induration, and purulent discharge.
RESULTS: PEG infections occurred in 22 patients. During the first 12-month interval, 0 of 25 patients (0%) had PEG-related infections; during the second 12-month interval, four of 37 patients (10.8%); and during the third 12-month interval, 18 of 64 patients (28.1%) (p < 0.05). Cultures from 14 of 22 peristomal infections grew methicillin resistant Staphylococcus aureus (nine), pseudomonads (three), and other organisms (two). One hundred twenty-four of 126 patients received prophylactic antibiotics or were receiving concomitant antibiotics. Of the infected patients, 21 of 22 (95.5%) received prophylaxis, and 11 of 22 (50%) were receiving concomitant antibiotics before PEG. In the noninfected group, 78 of 104 (75%) received prophylaxis, and 47 of 104 (45.2%) received concomitant antibiotics.
CONCLUSIONS: Methicillin resistant Staphylococcus aureus is emerging as a major pathogen in PEG site infections. Further prospective studies are needed to establish whether current prophylactic antibiotic recommendations are adequate.
