The INCIDENCE STUDY OF POST-OPERATIVE SKIN INFECTIONS BY STAPHYLOCOCCUS AUREUS AND ANTIBIOTIC REACTIONS AT RSUD Dr. PIRNGADI MEDAN

Abstrak

Introduction: Infections acquired through healthcare facilities are a side effect that impacts patient safety globally. Post-operative skin infections defined by the CDC as wound infections that appear within 30 days of surgery. Predominant bacterial isolate that causes surgical wound infections is Staphylococcus aureus as well as the MRSA strain. The sensitivity level of Staphylococcus aureus to the antibiotic Vancomycin is known 100% followed by Linezolid, while the resistance level to Penicillin reaches 100%. After patient confirmed with post-operative skin infection, antibiotics are adjusted to bacteria causing the infection through examinations. Objective: This study is determine the incidence of post-operative skin infections due to Staphylococcus aureus at Dr Pirngadi Hospital Medan. Method: This study is a cross-sectional analytical descriptive study using secondary patient data in medical records. Results: The bacteria most commonly causes post-operative skin infections is Staphylococcus aureus with 19 samples (33.9%). The gender often experiences post-operative skin infections is men. Comorbidity often found was Diabetes Mellitus (35,7%). Bivariate tests were used to see relationship between Staphylococcus aureus with demographics, length of stay, and comorbidities. Results of antibiotic sensitivity test Staphylococcus aureus sensitive to Vancomycin, Nitrofurantoin, Tetracycline, Gentamycin, and Ceftriaxone, while 100% resistance to Penicillin. Multivariate tests show gender has significant effect on surgical wound infections by Staphylococcus aureus. Conclusion: Staphylococcus aureus was the dominant cause of surgical wound infections with 100% sensitivity to Vancomycin. Significant relationship was shown by age group with comorbidities and length of stay.
