Abstract:
An outbreak due to a methicillin-resistant S. aureus (MRSA) strain in an orthopaedic septic care unit was observed. 17 patients developed wound infections. Stronger regime of hygiene and chemotherapy and new technics of operations controlled the outbreak within 5 months. Studies of colonisation were performed at the care unit in march, june and august 1992. 618 isolates were investigated from patients, personnel and their environment. The frequencies of detected MRSA diminished from 30% in march only to 22% in august 1992. The long time persistence of endemic MRSA in a care facility was evident from the presence of MRSA even 5 months after the last infection.
Insights
A methicillin-resistant Staphylococcus aureus (MRSA) outbreak in an orthopaedic unit infected 17 patients. Enhanced hygiene and treatment controlled the spread, but MRSA persisted in the environment long-term.
Area of Science:
- Infectious Diseases
- Microbiology
- Healthcare Epidemiology
Context:
- An outbreak of methicillin-resistant Staphylococcus aureus (MRSA) occurred in an orthopaedic septic care unit.
- Seventeen patients developed wound infections during the outbreak.
- The healthcare facility implemented enhanced hygiene, chemotherapy, and surgical techniques to control the outbreak.
Purpose:
- To investigate the epidemiology and control of a methicillin-resistant Staphylococcus aureus (MRSA) outbreak in an orthopaedic septic care unit.
- To assess the effectiveness of implemented control measures.
- To evaluate the persistence of MRSA in the healthcare environment post-outbreak.
Summary:
- The outbreak involved 17 patients with wound infections caused by a specific MRSA strain.
- Control measures, including stricter hygiene, chemotherapy, and new surgical techniques, were implemented over 5 months.
- Surveillance of MRSA colonization in patients, personnel, and the environment showed a decrease from 30% to 22% between March and August 1992.
- MRSA was detected in the environment even 5 months after the last patient infection, indicating long-term persistence.
Impact:
- Demonstrates the effectiveness of multi-faceted control strategies in managing MRSA outbreaks in orthopaedic settings.
- Highlights the challenge of eradicating endemic MRSA due to its long-term environmental persistence.
- Provides insights into surveillance and control of healthcare-associated infections (HAIs) caused by resistant bacteria.
