Background: 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. Objective: 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. Methods: 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. Results: 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.

1031 Background: Breast cancer brain metastasis (BCBM) de novo is associated with the worst prognosis among all types of metastases in breast cancer (BC). Analysis of factors associated with BCBM stratified by subtype of BC could lead to earlier identification of metastasis. Methods: 1,268 patients with BCBM at the time of BC diagnosis and known clinical subtype (580 HR+/HER2-, 225 HR+/HER2+, 176 HR-/HER2+, and 287 HR-/HER2-) who were ≥ 20 years of age from 2010 to 2017 were identified using the NCI’s Surveillance, Epidemiology, and End Results (SEER) Program 18 registry. Baseline characteristics and survival were analyzed using Chi-Square and Kaplan-Meier methods. Results: Patients with HR-/HER2+ BC were the most likely to present with BCBM, compared to all BC patients (prevalence of 13.9% vs. 4.7%; p<0.001). Further analysis demonstrated that HER2+ patients had an odds ratio of presenting with BCBM of 2.52 (95% CI: 2.24-2.84) compared to HER2- patients. Interestingly, in patients ages 20-39 with HR-/HER2+ BC, higher rates of brain metastases are noted within the BCBM group compared to all HR-/HER2+ breast cancer cases (28% vs. 7.6%; p<0.001). The same trend is seen within the HR-/HER2+ African American population, with those in the BCBM group experiencing higher rates of brain metastases compared to all BC cases with the same subtype (14.3% vs. 5.9%; p<0.001). Upon exploring insurance demographics, uninsured patients with HR-/HER2+ BCBM had much higher rates of brain metastases compared to all HR-/HER2+ BC cases (14.8% vs 6.4%; p=0.001). When examining TNM status, significant associations were noted between brain metastases and increased tumor and nodal status. Patients with T4 or N3 status with HR-/HER2+ BCBM exhibited much higher rates of metastasis compared to all BC cases with the same subtype (p<0.001). Analysis of survival outcomes showed a median overall survival of 12 months for patients with HR-/HER2+ BCBM. The results displayed in the table below show that HR-/HER2- BCBM patients had the lowest 5-year percent survival, while HR+/HER2+ BCBM patients had the highest 5-year survival. Conclusions: This SEER database study provides insight into the demographics, clinical variables, and outcomes for BC clinical subtypes, specifically HR-/HER2+, from 2010 to 2017 in the United States. HR-/HER2+ breast cancer patients within the noted high-risk populations should be made aware of the increased rates of brain metastases compared to the general BC population, as earlier identification of brain metastases within the HR-/HER2+ cohort could improve patient survival.[Table: see text]
