Percutaneous endoscopic gastrostomy as an unrecognized source of methicillin-resistant Staphylococcus aureus
1Department of Medicine, East Tennessee State University, College of Medicine, Johnson City.
Abstract:
Methicillin-resistant Staphylococcus aureus (MRSA) caused colonization or infection around the gastrostomy site of seven hospitalized patients, five of whom were in the long-term care unit. All cultures of gastrostomy sites were retrospectively reviewed, and 28% had MRSA. The gastrostomy site was responsible for 6.3% of all MRSA cultures, and 12.5% of all MRSA-positive patients with gastrostomy site cultures had involvement at that site. The implications of MRSA and gastrostomy tubes are discussed.
Insights
Methicillin-resistant Staphylococcus aureus (MRSA) can colonize or infect gastrostomy sites in hospitalized patients. This study found MRSA in 28% of gastrostomy site cultures, highlighting a significant risk.
Area of Science:
- Infectious Diseases
- Medical Microbiology
- Patient Safety
Background:
- Methicillin-resistant Staphylococcus aureus (MRSA) is a significant healthcare-associated pathogen.
- Gastrostomy tubes are common in hospitalized patients, particularly in long-term care settings.
- The risk of MRSA colonization or infection at gastrostomy sites requires investigation.
Purpose of the Study:
- To determine the prevalence of MRSA colonization or infection at gastrostomy sites.
- To assess the contribution of gastrostomy sites to overall MRSA infections in hospitalized patients.
Main Methods:
- Retrospective review of all gastrostomy site cultures.
- Microbiological analysis to identify MRSA.
- Analysis of patient demographics and unit location (long-term care).
Main Results:
- MRSA was identified in 28% of all gastrostomy site cultures reviewed.
- Gastrostomy sites accounted for 6.3% of all MRSA cultures analyzed.
- 12.5% of MRSA-positive patients with gastrostomy site cultures had site involvement.
Conclusions:
- Gastrostomy sites represent a potential reservoir for MRSA in hospitalized patients.
- Increased vigilance and infection control measures are warranted for patients with gastrostomy tubes.
- Further research into MRSA transmission dynamics related to gastrostomy tubes is recommended.
