Coronavirus disease 2019 (COVID-19) has made it imperative to focus on strategies to improve hand hygiene to minimize threats of viral transmission in hospitals.

We investigated the potential of using ultraviolet (UV) light as a visual tool in hand-hygiene education to bring awareness of individual handwashing effectiveness to healthcare workers.

In 2020, 117 individuals participated in the simulation and completed surveys on proper handwashing technique. Of these, 114 were first-year residents and fellows. Surveys of confidence in hand hygiene were obtained before and after formal hand-hygiene education utilizing UV light with Glo Germ lotion. The UV light and Glo Germ lotion were used to identify deficiencies in individual handwashing technique.

With a total response rate of 97.4%, first-year residents and fellows demonstrated a significant decrease in handwashing confidence in pre- and posteducation surveys. Study participants who had had formal hand-hygiene training in the previous 3 years also indicated confidence in hand hygiene similar to those who had not had previous hand-hygiene training. Conclusions: Overall, resident interns and fellows may have falsely elevated their hand-hygiene confidence levels. However, conclusions regarding the confidence of residents and fellows individually could not be made due to sample size. Many healthcare personnel practice improper handwashing techniques, which may be improved with education and training that includes UV light.

To evaluate educational level as a contributing factor in handwashing compliance.

Observation of hand washing opportunities was performed for approximately 12 weeks before an announced Joint Commission on Accreditation of Healthcare Organizations (JCAHO) visit and for approximately 10 weeks after the visit. Trained observers recorded the date, time, and location of the observation; the type of healthcare worker or hospital employee observed; and the type of hand hygiene opportunity observed.

University of Toledo Medical Center, a 319-bed teaching hospital.

A total of 2,373 observations were performed. The rate of hand washing compliance among nurses was 91.3% overall. Medical attending physicians had the lowest observed rate of compliance (72.4%; P < .001). Nurses showed statistically significant improvement in their rate of hand hygiene compliance after the JCAHO visit (P = .001), but no improvement was seen for attending physicians (P = .117). The compliance rate in the surgical intensive care unit was more than 90%, greater than that in other hospital units (P = .001). Statistically, the compliance rate was better during the first part of the week (Monday, Tuesday, and Wednesday) than during the latter part of the week (Thursday and Friday) (P = .002), and the compliance rate was better during the 3 PM-1 1 PM shift, compared with the 7 AM-3 PM shift (P < .001). When evaluated by logistic regression analysis, non-physician healthcare worker status and observation after the JCAHO accreditation visit were associated with an increased rate of hand hygiene compliance.

An inverse correlation existed between the level of professional educational and the rate of compliance. Future research initiatives may need to address the different motivating factors for hand hygiene among nurses and physicians to increase compliance.
