Microbial colonization of the hands of residents

Abstract:
To determine whether carriage of resistant Gram-positive organisms by residents increases over time, the dominant hand of pediatric residents was cultured. Among first-year residents, 53 Gram-positive organisms were isolated; 12 were resistant to oxacillin, 13 to clindamycin. Six residents had organisms resistant to both; 14 carried at least one resistant to either. Among third-year residents, 46 Gram-positive organisms were cultured; 9 were resistant to oxacillin, 6 to clindamycin. Three residents carried organisms resistant to both; 10 carried at least one resistant to either. Colonization with resistant Gram-positive organisms did not increase with length of training.
Insights
Resident colonization with antibiotic-resistant Gram-positive organisms did not increase with training duration. Cultures from pediatric residents showed similar rates of resistant bacteria carriage between first and third years.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Healthcare Epidemiology
Background:
- Healthcare professionals can act as reservoirs for antibiotic-resistant organisms.
- Understanding colonization dynamics in residents is crucial for infection control.
Purpose of the Study:
- To investigate the longitudinal carriage of resistant Gram-positive organisms among pediatric residents.
- To determine if the duration of residency training correlates with increased colonization by resistant bacteria.
Main Methods:
- Cultures were taken from the dominant hand of pediatric residents at different training levels.
- Isolated Gram-positive organisms were tested for resistance to oxacillin and clindamycin.
Main Results:
- First-year residents showed carriage of resistant Gram-positive organisms, with specific rates for oxacillin and clindamycin resistance.
- Third-year residents exhibited similar colonization patterns and resistance rates compared to first-year residents.
- No significant increase in colonization with oxacillin- or clindamycin-resistant Gram-positive organisms was observed with increased training.
Conclusions:
- Length of pediatric residency training does not appear to increase the carriage of resistant Gram-positive organisms.
- Further research may explore other factors influencing resident colonization with antibiotic-resistant bacteria.
