[Postoperative endophthalmitis: 2000-2002 results in the XV-XX National Ophthalmologic Hospital].
PURPOSE: Prevention of nosocomial infection is a priority for the Infection Control Committee (ICC). Following their recommendations, the XV-XX National Ophthalmologic Hospital's ICC conducted a survey on cases of infection and we report these results for the 2000-2002 period. METHODS: During the 2000-2002 period, 21,384 programmed intraocular surgeries were done. Every day, a hygiene coordinator was informed of each bacterial or fungal laboratory test on intraocular samples and for all patients who were hospitalized for endophthalmitis. After data analysis with a referent ICC physician, resulting infection was declared postoperative nosocomial endophthalmitis. For these patients, prophylactic antibiotic use, the surgery report, and bacterial laboratory test results were reviewed. RESULTS: The overall 3-year incidence of suspected postoperative endophthalmitis after intraocular surgery was 2.0 per 1000 (42 cases). Confirmed microbiological growth was demonstrated in 19 cases (45%). For cataract surgery, the incidence was 1.0 per 1000 for acute-onset culture-proven postoperative endophthalmitis, 0.1 per 1000 for delayed culture-proven postoperative endophthalmitis, 2.1 per 1000 for acute-onset suspected postoperative endophthalmitis and 0.5 per 1000 for delayed suspected postoperative endophthalmitis. Gram-positive cocci were isolated in 77%. Twenty-one patients received systemic prophylactic antibiotics. Bacterial growth was positive in five of these 21 cases. For two cases, organisms were resistant to the prophylactic antibiotics used. CONCLUSION: Monitoring postoperative nosocomial infection is mandatory to detect incidence variation and evaluate infection control management. Prophylactic antibiotic efficacy remains to be evaluated.
