Stethoscopes or Maybe "Bacterioscopes" - Is hand Hygiene Solely Capable of Preventing Hospital-Associated Infections?

The stethoscope remains an indispensable diagnostic tool for medical students. Improper stethoscope hygiene may cause bacterial infections, including hospital-associated infections (HAIs), which challenge the Polish medical system. The study's main objective was to evaluate the hygiene habits declared by medical students. Moreover, microbiological control with the characteristics of potentially pathogenic microorganisms was performed. The study included 66 medical students from the Faculty of Medicine at the Jagiellonian University Medical College in Cracow, Poland. The participants filled in an anonymous questionnaire. Stethoscope contamination was assessed through isolation, identification, testing of antibiotic resistance, and clonality of the isolates bacterial pathogens. The survey showed that only 30.3% of students cleaned their stethoscopes after each patient, and 1.5% never did this. Of the 66 stethoscopes tested, 100% were positive for bacterial growth. Staphylococcus spp. was the most frequently isolated contaminant (50.5%). The questionnaire results demonstrated the necessity of the validated procedures for cleaning the stethoscopes. Stethoscopes used by medical students are contaminated with numerous bacterial species, including multidrug-resistant organisms. The clonal structure of the MRSA and MRSE populations acquired from stethoscopes has been demonstrated. Our results confirm the possibility that these medical devices mediate the spread of hazardous pathogens in the hospital environment. Practical exercises are essential to forming the correct hygiene habits involving stethoscopes, which enable practicing and checking the correctness of the established skills.

Rigorous Hand Hygiene Practices Among Health Care Workers Reduce Hospital-Associated Infections During the COVID-19 Pandemic

The experiences of these recent months have left us with as many new questions as they have given us new solutions. The main question that infection prevention and control department is having these days is “Why have hospital-associated infections (HAIs) reduced during COVID-19 pandemic?” What is the one unique strategy that has brought decline in increasing HAIs? Would it be appropriate to say that rigorous hand hygiene practices among health care workers (HCWs) have reduced HAIs in a tertiary care hospital of Pakistan? This commentary is written to understand the effect of rigorous hand hygiene among HCWs on number of HAIs during COVID-19 pandemic. Given the seriousness of this outbreak, it was observed that the hand hygiene has occupied a new place of importance in the minds of HCWs. We observed 4 times increase in the consumption of hand sanitizers after COVID-19 outbreak. The increased consumption of hand sanitizers was reflected in improved hand hygiene practices. A reduction was observed in the number of HAIs after the COVID-19 outbreak, and we assume that the dip in HAIs is associated with the improvement in hand hygiene practices in the recent months. In the wake of COVID-19 pandemic, these trends reassure us that hand hygiene compliance by HCWs alone can be effective in reducing HAIs in a hospital setting.
