Methicillin-resistant Staphylococcus aureus contamination and distribution in patient’s care environment at Muhimbili National Hospital, Dar es Salaam-Tanzania

Article scientifique 2018 Anglais

Résumé

OBJECTIVE: Environmental contamination with methicillin-resistant Staphylococcus aureus in routine medical care settings poses an increased risk of health care associated infections through cross-transmission. This study aimed at determining the magnitude and distribution of methicillin-resistant S. aureus contamination among various items in patients' care surroundings at Muhimbili National Hospital, Tanzania's largest tertiary hospital. RESULTS: A total of 200 environmental samples from high touch items were processed and out of these methicillin-resistant S. aureus was 19.5% with significantly higher contamination in general wards. Patients' beds surfaces were the most contaminated among studied items (43.7%), whilst the surgical trolleys were least contaminated (7.7%). Presence of 10 or more patients in a room was an important significant correlate for methicillin-resistant S. aureus contamination by bivariate logistic regression model (odds ratio: 4.75, 95% confidence interval 1.624-13.895, p = 0.004). These findings warrant further study of decontamination practices and improved infection control mechanisms, especially in light of the drug resistant isolates identified.
