Methicillin-resistant Staphylococcus aureus in patients with spinal cord injury
1Spinal Cord Injury Service, Long Beach Veterans Administration Medical Center, CA 90822, USA.
Abstract:
During the past decade, methicillin-resistant Staphylococcus aureus (MRSA) has become a major cause of nosocomial and community-acquired infections in the United States. A retrospective chart review of MRSA-positive cases from January 1990 to December 1994 was done to assess the extent of the problem, the factors associated with MRSA acquisition, and the effectiveness of a Center for Disease Control (CDC) protocol to treat MRSA infection in a population with spinal cord injury (SCI). Seventy-four percent of the patients acquired MRSA during their hospitalization. Urine was the most common site of colonization, and 73 percent of the patients with positive urine cultures managed their bladders with indwelling catheters. Implementation of the CDC protocol in 1991 was associated with a decrease in the MRSA incidence rate in subsequent years. Other simple methods of treatment, such as bladder irrigation, were also effective. To control the spread of MRSA, a continual concerted effort by hospital staff through education and implementation of the MRSA protocol is necessary.
Insights
Methicillin-resistant Staphylococcus aureus (MRSA) is a significant infection risk for hospitalized patients, especially those with spinal cord injury (SCI). Implementing CDC protocols and simple treatments like bladder irrigation helped reduce MRSA rates.
Area of Science:
- Infectious Diseases
- Hospital Epidemiology
- Clinical Medicine
Background:
- Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a leading cause of healthcare-associated and community-acquired infections in the U.S.
- Patients with spinal cord injury (SCI) represent a vulnerable population for nosocomial infections.
Purpose of the Study:
- To evaluate the prevalence of MRSA in SCI patients.
- To identify factors contributing to MRSA acquisition in this population.
- To assess the efficacy of the Centers for Disease Control (CDC) protocol for MRSA treatment.
Main Methods:
- Retrospective chart review of MRSA-positive cases between January 1990 and December 1994.
- Analysis of patient demographics, infection sites, and treatment strategies.
- Comparison of MRSA incidence rates before and after protocol implementation.
Main Results:
- 74% of MRSA cases were acquired during hospitalization.
- Urinary tract colonization was most common, frequently associated with indwelling catheters (73%).
- Implementation of the CDC protocol correlated with a reduced MRSA incidence rate.
Conclusions:
- Hospital-acquired MRSA is a substantial issue in SCI patients, with urinary tract infections and catheter use being significant factors.
- The CDC protocol, alongside interventions like bladder irrigation, demonstrated effectiveness in controlling MRSA spread.
- Sustained efforts in staff education and protocol adherence are crucial for MRSA infection control.
