METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS NASAL CARRIAGE- ITS PREVALENCE, RISK FACTORS, ANTIBIOTIC SUSCEPTIBILITY AND DECOLONIZATION AMONG HEALTHCARE WORKERS IN A TERTIARY CARE HOSPITAL IN SOUTH INDIA.

Abstract


Aims: To determine the prevalence of MRSA carriage among healthcare workers, the antibiotic sensitivity pattern of the isolated strains, to attempt
decolonization of the carriers and to assess effectiveness of the decolonization regimen.
Materials and method: Nasal swabs collected from 150 health care workers were processed for bacterial identification and antibiotic sensitivity
testing. After decolonization, repeat cultures were performed to assess the effectiveness.
Results: Nasal carriage of MRSA among healthcare workers was found to be 4.7%. The MRSA carriage was found high among nurses (5.5%). A
significant association with MRSA was noted among health workers who have nasal problems like sinusitis, allergic rhinitis and nasal septal
deviation. Topical mupirocin and chlorhexidine bath was found to be effective in eradicating MRSA carriers.
Conclusion: In hospitals, nasal carriage of MRSA must be regularly screened and give an early warning of the presence of antimicrobial resistant
pathogens among HCWs.
