Staphylococcus aureus: a review of the literature
Abstract:
Staphylococcus aureus has a long association with nosocomial infection. Problems date from the 1950s, although methicillin-resistant Staphylococcus aureus (MRSA) did not emerge until the following decade. Initially the pathogenicity of antibiotic-resistant strains was underestimated, and is still sometimes questioned, but today most authorities consider MRSA a serious threat, especially given current preoccupation with cost-effectiveness within the health service: nosocomial infection is associated with increased expenditure and may be regarded as a hallmark of indifferent nursing and medical care. This review documents the emergence of MRSA and recognition of the ensuing problems throughout the 1980s and early 1990s, with suggestions for nursing activities which could contribute towards improved control. Lessons learnt during outbreaks are seen to be of value, but there is also a need for staff at ward level to review routine practice continually so that awareness of activities likely to result in cross-infection is maintained. The use of protective clothing emerges as less important than handwashing, which may be periodically audited to maintain standards.
Insights
Methicillin-resistant Staphylococcus aureus (MRSA) emerged as a significant nosocomial threat. Effective control hinges on continuous staff awareness and prioritizing handwashing over protective clothing.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Hospital Epidemiology
Background:
- Staphylococcus aureus has been linked to hospital-acquired infections since the 1950s.
- Methicillin-resistant Staphylococcus aureus (MRSA) emerged in the 1960s, with its pathogenicity initially underestimated.
- MRSA is now recognized as a major threat, contributing to increased healthcare costs and reflecting care quality.
Purpose of the Study:
- To document the emergence of MRSA and the recognition of associated problems during the 1980s and early 1990s.
- To suggest nursing interventions for improved MRSA control.
- To emphasize the importance of ongoing staff education and practice review for infection prevention.
Main Methods:
- Literature review documenting the historical emergence and recognition of MRSA.
- Analysis of nursing activities and their impact on infection control.
- Emphasis on lessons learned from outbreaks and routine practice evaluation.
Main Results:
- MRSA became a significant nosocomial pathogen, posing a serious threat to patient safety.
- Outbreak experiences provided valuable lessons for infection control strategies.
- Continuous ward-level practice review is crucial for maintaining awareness of cross-infection risks.
Conclusions:
- Handwashing is a more critical intervention for MRSA control than the use of protective clothing.
- Periodic auditing of handwashing practices is essential to maintain high standards.
- Sustained vigilance and adaptation of nursing practices are necessary to combat MRSA effectively.
