Hypothesis
What are the trends in antibiotic susceptibility patterns of MRSA isolates from hospitals in Riyadh, Saudi Arabia?
Conclusion
Quinupristin/dalfopristin and linezolid are effective against MRSA, but resistance is developing, necessitating careful use.
Supporting Evidence
- MRSA prevalence in the study hospitals ranged from 12% to 49.4%.
- Approximately 41.5% of the isolates came from patients in extreme age groups.
- Linezolid and quinupristin/dalfopristin were the most effective antibiotics against inpatient isolates.
Takeaway
This study looked at how well MRSA bacteria respond to different antibiotics in hospitals. It found that some antibiotics still work, but others are becoming less effective.
Methodology
The study analyzed 512 MRSA isolates from 6 hospitals, documenting antibiotic susceptibilities and using statistical analysis with SPSS.
Potential Biases
Potential bias due to the selection of hospitals and the absence of environmental strain data.
Limitations
The study did not include environmental strains and relied on data from specific hospitals, which may not represent all MRSA cases.
Participant Demographics
Mean age of participants was 44 years, with 64.4% male and 35.6% female.
