Abstract Historically, cancers diagnosed via the emergency department (ED) portend a poor prognosis. Recent data from the United States are sparse, and analyses of cancers detected in the years following ED visits are lacking. Thus, we analyzed data from nine rural U.S. Midwest counties included within the population-based Rochester Epidemiology Project (2015–2021). Participants without a history of cancer (N = 42,074) who did not receive ED care were matched 1:1 to ED participants on the date of ED visit, age, sex, race, ethnicity, and county of residence. Analyses were restricted to participants with records ≤2 years prior to ED or index visit and ≥30 days after. HRs and 95% confidence intervals (CI) comparing cancer incidence and deaths among ED and non-ED participants were estimated from Cox proportional hazards regression models, either unadjusted or adjusted for covariates. Cumulative cancer incidence curves accounting for competing risks of death and survival (all cause and cancer-specific) were estimated. The median follow-up was 6.3 years, with 2,719 (6.46%) cancers diagnosed among ED participants and 3,139 (7.46%) among non-ED participants. ED participants experienced lower cancer risk overall (HRAdjusted = 0.70; 95% CI, 0.66–0.74; P = 8.89 × 10−31), specifically for breast cancer, prostate cancer, melanoma, and secondary cancers. Cancer-specific mortality was higher among ED participants (HRAdjusted = 1.76; 95% CI, 1.49–2.08; P = 3.62 × 10−11). Compared with non-ED participants, ED participants experienced a lower incidence of cancer but higher overall cancer-specific mortality, suggesting that subsets of ED patients may benefit from postvisit preventive interventions. Prevention Relevance: This cohort analysis shows that cancer incidence over 6 years was lower among participants after an ED visit than among matched non-ED participants, whereas cancer-specific mortality was higher in the ED group (HRAdjusted = 1.76; 95% CI, 1.49–2.08; P = 3.62 × 10−11), suggesting the potential benefit of preventive interventions.

Abstract Background: Human Papillomavirus (HPV) vaccination rates remain low in the U.S., particularly among minorities and low-income patients. In 2014, a Mayo Clinic study of uninsured, low-income, working, Volunteer in Medicine (VIM) Clinic patients in Jacksonville, Florida found a statistically significant lower awareness of HPV (50.3% vs 63.6%) and the HPV vaccine (32.1% vs 62.7%) than the national population. As a result, our team collaborated with Merck to develop a free HPV vaccination program and video education campaign for VIM patients. Methods: We assessed VIM patients HPV vaccination knowledge, awareness, and prevalence of hesitancy towards receiving the vaccine. VIM patients (ages 18-45) with no previous history of HPV vaccination were invited to participate in this study. The Parents Attitudes about Childhood Vaccines (PACV) survey was used to evaluate vaccine hesitancy. Patients who declined the HPV vaccine were shown an educational video to assess effectiveness in persuading patients’ opinion. Each participant received a vaccine hesitancy PACV score, which was compared with their vaccine disposition. Mayo Clinic IRB approval of the study was obtained. Results: Our analysis included 43 patients (34 females, 9 males) with a median age of 40 (age range 27- 45). Patients had overall knowledge of HPV of 88.4%, with 69.8% having heard of the HPV vaccine. 85.7% PACV survey respondents were deemed non-hesitant (PACV scores 0-49), and 80.6% of the non-hesitant subset (29/36) agreed to undergo vaccination. The average PACV score of vaccine-interested participants was lower (25.2) than the average of participants not interested in the vaccine (36.7). Black participants had a statistically significant higher PACV score than White participants. The PACV scores of individuals who were already familiar with the HPV vaccine were significantly lower than those of participants who were unfamiliar with the HPV vaccine. Only 20% (2/10) of individuals, who had previously declined vaccination, agreed to receive the HPV vaccine after viewing the HPV educational video. Of the 33 participants who agreed to receive the free HPV vaccine, only 9 (27.3%) completed all three doses. Conclusions: HPV vaccine awareness and knowledge at VIM increased compared to the 2014 cohort. Vaccine hesitancy was not observed in most patients, yet video education was effective in only a small portion of patients with vaccine hesitancy. Additionally, a minority of patients who agreed to receive the free HPV vaccine series completed all three doses. Our results suggests that free HPV vaccination and video education is not sufficient to achieve adequate vaccination rates among low-income uninsured young adults, nor overcoming vaccine hesitancy. Innovative measures are warranted to improve vaccination rates in this population. Citation Format: Hiram Diaz, Gerardo Colon-Otero, Laura M. Pacheco-Spann, Christopher C.

AbstractAlthough endometrial cancer is often diagnosed at an early curable stage, the incidence and mortality from endometrial cancer is rising and minority women are particularly at risk. We hypothesize that delays in clinical presentation contribute to racial disparities in endometrial cancer mortality and treatment-related morbidity. Improved methods for endometrial cancer risk assessment and distinguishing abnormal uterine bleeding and postmenopausal bleeding from physiologic variation are needed. Accordingly, we propose a multipronged strategy that combines innovative patient education with novel early detection strategies to reduce health impacts of endometrial cancer and its precursors, especially among Black women. Futuristic approaches using gamification, smartphone apps, artificial intelligence, and health promotion outside of the physical clinic hold promise in preventing endometrial cancer and reducing morbidity and mortality related to the disease, but they also raise a number of questions that will need to be addressed by future research.
