Hypothesis
What is the current prevalence of methicillin resistance among Staphylococcus aureus isolates in Trinidad?
Conclusion
The prevalence of MRSA in the hospital increased from 12.5% in 1999 to 20.8% in 2004.
Supporting Evidence
- The major sources of MRSA were surgical/burn wounds (60.1%) and urine (15.5%).
- Resistance rates for tetracycline were similar among both MRSA (78.7%) and MSSA (73.5%).
- All MRSA isolates were fully sensitive to vancomycin.
Takeaway
This study found that more people in Trinidad are getting infections from a type of bacteria called MRSA, which is hard to treat.
Methodology
Analyzed 2430 S. aureus isolates over 6 years from various clinical sources using antimicrobial susceptibility testing.
Limitations
The study did not differentiate between inpatient and outpatient isolates.
Participant Demographics
The population of Trinidad is about 1.3 million.
