Risk factors and associated problems in the management of infections with methicillin resistant Staphylococcus aureus

Area of Science:

• Medical Microbiology
• Infectious Diseases
• Hospital Epidemiology

Background:

• Methicillin-resistant Staphylococcus aureus (MRSA) poses a significant challenge in hospital settings, necessitating effective control strategies.
• Understanding the factors contributing to MRSA persistence in hospital-acquired infections is crucial for developing targeted interventions.

Purpose of the Study:

• To identify key factors influencing the persistence of MRSA in patients with hospital-acquired infections.
• To evaluate alternative, cost-effective antibiotic options for treating MRSA infections.

Main Methods:

• A six-month study involving 50 patients diagnosed with MRSA infection.
• Data collection on treatment modalities and risk factors using a predefined protocol.
• Determination of minimum inhibitory concentrations (MICs) for commonly used antibiotics against MRSA isolates.

Main Results:

• Prolonged postoperative morbidity, prior antibiotic therapy, and emergency admissions were identified as significant risk factors.
• MRSA isolates were predominantly found in postoperative cases undergoing emergency surgeries (70%).
• Ofloxacin showed efficacy in a subset of cases, while combinations of rifampicin with ofloxacin or clindamycin emerged as viable alternatives. Ofloxacin was the most cost-effective treatment option.

Conclusions:

• Minimizing identified risk factors is essential for managing MRSA infections.
• Exploring alternate, cost-effective combination therapies can improve treatment outcomes for MRSA infections.
