Bare below the elbows

The Association between Hand Disinfection Techniques and Their Barriers, as Well as the "Bare below the Elbows" Concept, among Healthcare Professionals-A Study Based on a Polish Population

Hand hygiene is the most effective way to prevent nosocomial infections. Nevertheless, the hands of healthcare professionals are still the primary route of transmission of pathogens responsible for such infections. The aim of this study was to evaluate hand disinfection techniques and investigate the risk factors that may explain the improper hand disinfection techniques among healthcare workers. We selected 7544 hospital workers directly involved in patient care. We recorded data based on the questionnaires, demographic data, and the preparation of hands for disinfection, including risk factors. Correct hand disinfection was verified by COUCOU BOX, with a UV camera. Proper hand disinfection was demonstrated among 4879 (64.7%) subjects, while 2665 (35.3%) subjects disinfected their hands incorrectly. In most places of work, nurses properly disinfected their hands more often than the physicians, particularly in general departments (62.1% vs. 69.2%; p = 0.0019). We observed that long nails and artificial/polished nails were more often observed in the group of nurses than in the group of physicians (7.3% vs. 4.7%, respectively; p = 0.0006 and 19.3% vs. 10.1%; p = 0.0000), while an inverse relationship was found in relation to watches (24.0% vs. 12.0%; p = 0.0000) and long sleeves (24.4% vs. 8.1%; p = 0.0000). Incorrect and less effective hand hygiene among some groups of hospital workers is still present. Therefore, the continuation of education actions concerned with hand hygiene among healthcare workers is needed.

Comparing colony-forming units in inpatient nurses: Should military nurses who provide patient care wear hospital-provided scrubs?

OBJECTIVE

To compare bacterial contamination of military-approved uniforms and hospital-provided scrubs donned by nursing staff in an inpatient setting.

DESIGN

Randomized experimental crossover study.

SETTING

Large academic military medical center.

METHODS

Inpatient units were randomized to predetermine the order of uniform sampling. Participants included nursing staff who provided direct patient care across 7 eligible inpatient units. Sampling of 6 designated sites on the uniform was completed on arrival to work, at ~4 hours into their shift, and at the 8-hour time point, for a total of 18 samples. Sampling of each participant occurred on 2 separate occasions, once in a military-approved uniform, and once in hospital-provided scrubs. After 24 hours of incubation, a colony-counting machine was used to calculate the total colony-forming units (CFU) of the sample.

RESULTS

Across all time points, military-approved uniforms demonstrated a 2-fold bacterial increase at the abdominal site and 3-fold increases at the sleeve cuff and waist pocket regions compared to the same regions on hospital-provided scrubs.

CONCLUSION

Nurses should be aware that bacteria are present at much higher levels on their personal military uniforms compared to hospital-provided scrubs. Additional research is needed to determine whether these findings are a function of wear, laundering, or environmental factors. Nurses should adhere to daily uniform washing to reduce bacterial load and minimize risk of nosocomial infections to the patients they care for.

[Contamination of workwear in medical doctors and nursing stuff]

BACKGROUND

The hands of medical stuff are the most important vectors for the transmission of pathogens in the hospital. Furthermore a "bare below the elbows dress code" has been introduced in Great Britain.

OBJECTIVES

Aim of this study was to investigate whether workwear contamination of the medical stuff by pathogens is similar to the contamination of their hands and whether wearing workwear is associated with increased transmission risk.

MATERIAL AND METHODS

In total 54 swabs were collected from nursing stuff, medical doctors, patients and hospital work material.

RESULTS

Patients had a statistically significant more dense colonization with bacteria (median = 73 colony-forming units (CFU)), than the sleeves of the doctor's coat (median = 36 CFU, p = 0,005), followed by workwear of the nursing stuff at the end of a shift (median = 23 CFU, p < 0,001) and the hospital work material (median = 15 CFU, p < 0,001). Isolated pathogens were coagulase-negative staphylococci, Staphylococcus aureus, Enterobacter cloacae and Acinetobacter species.

CONCLUSIONS

Contaminated work wear presents a relevant risk for the transmission of pathogens. A "bare below the elbow dress-code" or the daily change of the doctor's coat appear both to represent reasonable measures to reduce the transmission risk of pathogens in hospitals.
