Publication Seroprevalence and estimation of the impact of SARS-CoV-2 infection in older adults residing in Long-term Care Facilities in Chile(2022) Rubilar, Paola; Hirmas Adauy, Macarena; Matute, María Isabel; Browne, Jorge; Little, Cedric; Ruz, Gonzalo; Aguilera, Ximena; Avila, Carlos; Vial, Pablo; Gutknecht Mackenzie, TaniaIntroduction Older adults are at a higher risk of severe illness and death from COVID-19. This vulnera bility increases in those who live in long-term care facilities due to overcrowding, greater physical dependence, and contact with health workers. Evidence on the impact of the pan demic on these establishments in low- and middle-income countries has been scant. This study aims to determine the seroprevalence of SARS-CoV-2 in older people residing in long-term care facilities and estimate the impact of infection after the first wave of the pandemic. Methods A cross-sectional design with 2099 residents in three regions of Chile was carried out be tween September and November 2020. Measurement of antibodies was performed with a rapid test. The impact of SARS-CoV-2 infection was estimated with seropositive residents, those who had a history of positive polymerase chain reaction tests, and those who died from COVID-19. Bivariate analysis with the region, sex, age, history of COVID-19, physical dependence, and serological results were performed. In addition, we performed a correla tion analysis between the seroprevalence of the centers by the municipality and the rate of confirmed cases. Results The seroprevalence of SARS-CoV-2 antibodies in the three regions was 14.7% (95% confi dence interval: 13.2 to 16.3%), the infection impact was 46.4%, and the fatality rate was 19.6%. A significant correlation was found between the seroprevalence of older adults re siding in long-term care facilities and the cumulative incidence by municipalities. Conclusions The seroprevalence of older adults residing in long-term care facilities was higher than the general population. The high impact of infection among this population at the end of the first wave of the COVID-19 pandemic is similar to other countries. The centers' environ ment is directly related to COVID-19 infection. Morbidity and mortality monitoring sys tems should be implemented promptly to establish prevention and control measurPublication Barriers and Facilitators in Access to Diabetes, Hypertension, and Dyslipidemia Medicines: A Scoping Review(2022) Castillo-Laborde, Carla; Hirmas Adauy, Macarena; Matute, María Isabel; Jasmen, Anita; Urrejola, Oscar; Molina, Xaviera; Awad, Camila; Frey, Catalina; Pumarino, Sofia; Descalzi, Fernando; Ruiz, Tomás; Plass, BarbaraObjective: Identify barriers and facilitators in access to medicines for diabetes, hypertension, and dyslipidemia, considering patient, health provider, and health system perspectives. Methods: Scoping review based on Joanna Briggs methodology. The search considered PubMed, Cochrane Library, CINAHL, Academic Search Ultimate, Web of Science, SciELO Citation Index, and grey literature. Two researchers conducted screening and eligibility phases. Data were thematically analyzed. Results: The review included 219 documents. Diabetes was the most studied condition; most of the evidence comes from patients and the United States. Affordability and availability of medicines were the most reported dimension and specific barrier respectively, both cross-cutting concerns. Among high- and middle-income countries, identified barriers were cost of medicines, accompaniment by professionals, long distances to facilities, and cultural aspects; cost of transportation emerges in low-income settings. Facilitators reported were financial accessibility, trained health workers, medicines closer to communities, and patients' education. Conclusion: Barriers and facilitators are determined by socioeconomic and cultural conditions, highlighting the role of health systems in regulatory and policy context (assuring financial coverage and free medicines); providers' role bringing medicines closer; and patients' health education and disease management.
