Background: Globally, the levels of healthcare-associated infections especially those due to bacterial are significant and costly. Hense, the need to perform a timely assessment of surface contamination of bacterial origin in the major units of four different hospitals of the Littoral Region, Cameroon.
Method: A cross-sectional and descriptive study was conducted from December 2018 to May 2019. A simple random sampling was used to swap 10 selected equipment and materials in the mornings after disinfection but before the start of work. API staph, strep, and 20ETM gallery Biomerieux were used for identification.
Results: 119/236 (50.4%) showed bacterial growth, 33 different species of which S. aureus, 45/119 (37.81%), E. coli 6/119 (5.04%), and Acinetobacter spp 4/119(3.36%) were the most common contaminants. Patients’ bedside tables, office chairs, and patients’ bed rails were the highest contaminants respectively 14/119 (11.76%), 13/119 (10.92%) and 12/119 (10.08%). The Emergency units were the mainly contaminated area for Gram-positive cocci, 12/62 (19.35%) majority S. aureus 9/62 (14.51%) as most as Gram-negative non-Enterobacteriaceae 11/31(35, 48%) with a predominance of C. meningoseptica and M. heamolytica both 2/31(6.45%). Therefore for Enterobacteriaceae family, the highest level of bacterial isolates was recovered in laboratory 7/26 (26.92%), in which E. coli was predominantly reported 4/26 (15.38%). However, S. aureus was the only species found in all hospitals and units.
Conclusion: Hospital environment is a serious reservoir of bacteria. This work will help clinical care and decision making to take appropriate actions to improve sanitation and ensure control measures to limit the spread of hospital-acquired infections.
