How were we before? An analysis of the potential supply and inequality in the geographic access to critical resources for the COVID-19 treatment. / Como estávamos antes? Uma análise da oferta potencial e desigualdade de acesso geográfico aos recursos críticos para tratamento de COVID-19.

The objective was to analyze the situation of the Metropolitan Area of Brasília (AMB) before the onset of the COVID-19 pandemic, focusing on the availability and geographical accessibility of critical resources for the treatment of acute respiratory crises caused by the SARS-CoV-2 virus. Geographic mapping of the population within the territory and geolocation of health facilities and resources, construction of a relationship network between the potential demand simulated to the public health system and the supply of resources available in December 2019. The relationship analysis is based on the theory of complex networks crossing socioeconomic data available in the CENSUS and information from the National Registry of Health Establishments (CNES) and analyzing the micro relationship of census tracts with the stock and availability of health resources concerning Adult ICU Bed Type II/III and Respirators/Ventilators. The Federal District (DF) health facilities concentrate more than 75% of the relationships of potential access to critical resources for the treatment of COVID-19. Although the regions surrounding the DF, belonging to Goiás state, have the greatest relative vulnerability in the studied territory, they are also the most lacking in spatial accessibility and availability of resources, evidencing a care imbalance within the AMB region.

O objetivo deste artigo é analisar a situação da Área Metropolitana de Brasília (AMB) antes do início da pandemia de COVID-19 com foco na disponibilidade e acessibilidade de recursos críticos para o tratamento da crise aguda respiratória causada pelo vírus SARS-CoV-2. Mapeamento geográfico da população e geolocalização dos estabelecimentos e recursos de saúde, construção de rede de relacionamentos entre a demanda potencial ao sistema de saúde público e a oferta de recursos existente em dez/2019. Análise baseada na teoria de redes complexas cruzando dados socioeconômicos disponíveis no CENSO, dados do Cadastro Nacional de Estabelecimentos de Saúde (CNES) e o micro relacionamento dos setores censitários e suas populações com o estoque e disponibilidade de recursos do tipo Leito de UTI Adulto Tipo II/III e Respiradores Mecânicos. Estabelecimentos do Distrito Federal (DF) concentram mais de 75% dos relacionamentos de acesso potencial aos recursos críticos para o tratamento de COVID-19. Embora as regiões do entorno do DF, pertencentes ao Goiás, apresentem a maior vulnerabilidade relativa no território estudado, são também as mais carentes de acessibilidade e disponibilidade de recursos, evidenciando um desequilíbrio assistencial dentro da região da AMB.

Improving the adherence to COVID-19 preventive measures in the community: Evidence brief for policy

Objectives To identify evidence-based strategies to improve adherence to the preventive measures against the coronavirus disease (COVID-19) at the community level. Method This is an evidence brief for policy, combining research evidence specific to contextual knowledge from stakeholders. A systematic search was performed in 18 electronic databases, gray literature, and a handle search, including only secondary and tertiary studies that focused on the adherence of the general population to COVID-19 preventive measures in the community. Two reviewers, independently, performed the study selection, data extraction, and assessment of the quality of the studies. Relevant evidence has been synthesized to draft evidence-based strategies to improve adherence. These strategies were circulated for external endorsement by stakeholders and final refinement. Endorsement rates >80%, 60–80% and <60% were considered high, moderate, and low respectively. Results Eleven studies, with varying methodological qualities were included: high (n = 3), moderate (n = 3), low (n = 1), and critically low (n = 4). Three evidence based strategies were identified: i. Risk communication;ii. Health education to the general public, and iii. Financial support and access to essential supplies and services. The rates of endorsement were: 83% for risk communication, 83% for health education, and 92% for financial support and access to essential supplies and services. The evidence showed that an increase in knowledge, transparent communication, and public awareness about the risks of COVID-19 and the benefits of adopting preventive measures results in changes in people's attitudes and behavior, which can increase adherence. In addition, the guarantee of support and assistance provides conditions for people to adopt and sustain such measures. Conclusions These strategies can guide future actions and the formulation of public policies to improve adherence to preventive measures in the community during the current COVID-19 pandemic and other epidemics.

Dissemination interventions to improve healthcare workers' adherence with infection prevention and control guidelines: a systematic review and meta-analysis.

BACKGROUND: The COVID-19 pandemic has challenged health systems worldwide since 2020. At the frontline of the pandemic, healthcare workers are at high risk of exposure. Compliance with infection prevention and control (IPC) should be encouraged at the frontline. This systematic review aimed to assess the effects of dissemination interventions to improve healthcare workers' adherence with IPC guidelines for respiratory infectious diseases in the workplace. METHODS: We searched CENTRAL, MEDLINE, Embase, and the Cochrane COVID-19 Study Register. We included randomized controlled trials (RCTs) and cluster RCTs that assessed the effect of any dissemination strategy in any healthcare settings. Certainty of evidence was assessed using the GRADE approach. We synthesized data using random-effects model meta-analysis in Stata 14.2. RESULTS: We identified 14 RCTs conducted from 2004 to 2020 with over 65,370 healthcare workers. Adherence to IPC guidelines was assessed by influenza vaccination uptake, hand hygiene compliance, and knowledge on IPC. The most assessed intervention was educational material in combined strategies (plus educational meetings, local opinion leaders, audit and feedback, reminders, tailored interventions, monitoring the performance of the delivery of health care, educational games, and/or patient-mediated interventions). Combined dissemination strategies compared to usual routine improve vaccination uptake (risk ratio [RR] 1.59, 95% confidence interval [CI] 1.54 to 1.81, moderate-certainty evidence), and may improve hand hygiene compliance (RR 1.70; 95% CI 1.03 to 2.83, moderate-certainty). When compared to single strategies, combined dissemination strategies probably had no effect on vaccination uptake (RR 1.01, 95% CI 0.95 to 1.07, low-certainty), and hand hygiene compliance (RR 1.16, 95% CI 0.99 to 1.36, low-certainty). Knowledge of healthcare workers on IPC improved when combined dissemination strategies were compared with usual activities, and the effect was uncertain in comparison to single strategy (very low-certainty evidence). CONCLUSIONS: Combined dissemination strategies increased workers' vaccination uptake, hand hygiene compliance, and knowledge on IPC in comparison to usual activities. The effect was negligible when compared to single dissemination strategies. The adoption of dissemination strategies in a planned and targeted way for healthcare workers may increase adherence to IPC guidelines and thus prevent dissemination of infectious disease in the workplace.

Mask decontamination methods (model N95) for respiratory protection: a rapid review.

BACKGROUND: N95 respiratory protection masks are used by healthcare professionals to prevent contamination from infectious microorganisms transmitted by droplets or aerosols. METHODS: We conducted a rapid review of the literature analyzing the effectiveness of decontamination methods for mask reuse. The database searches were carried out up to September 2020. The systematic review was conducted in a way which simplified the stages of a complete systematic review, due to the worldwide necessity for reliable fast evidences on this matter. RESULTS: A total of 563 articles were retrieved of which 48 laboratory-based studies were selected. Fifteen decontamination methods were included in the studies. A total of 19 laboratory studies used hydrogen peroxide, 21 studies used ultraviolet germicidal irradiation, 4 studies used ethylene oxide, 11 studies used dry heat, 9 studies used moist heat, 5 studies used ethanol, two studies used isopropanol solution, 11 studies used microwave oven, 10 studies used sodium hypochlorite, 7 studies used autoclave, 3 studies used an electric rice cooker, 1 study used cleaning wipes, 1 study used bar soap, 1 study used water, 1 study used multi-purpose high-level disinfection cabinet, and another 1 study used chlorine dioxide. Five methods that are promising are as follows: hydrogen peroxide vapor, ultraviolet irradiation, dry heat, wet heat/pasteurization, and microwave ovens. CONCLUSIONS: We have presented the best available evidence on mask decontamination; nevertheless, its applicability is limited due to few studies on the topic and the lack of studies on real environments.

[Institutionalizing evidence-based policies in BrazilInstitucionalización de las políticas informadas por evidencia]. / Institucionalização das políticas informadas por evidências no Brasil.

OBJECTIVE: To evaluate capacities, organizational arrangements, and barriers to the implementation of Evidence Centers (NEvs) as part of Brazil's Evidence-Informed Policy Network (EVIPNet). METHOD: A mixed methods descriptive-analytical, multiple-case exploratory study was performed. Coordinators of active NEvs answered a questionnaire in three parts: participant characteristics, assessment of the capacity to "acquire, assess, adapt, and apply" evidence (4A), and open questions addressing organizational arrangements and barriers to the implementation of NEvs. RESULTS: The study included 15 NEvs, mostly from the Midwest; 73.3% were based in universities, while 20% were installed in state/city health departments or in the Ministry of Health. All coordinators had completed graduate training and 80% reported 1 to 5 years' experience with evidence-based policies as well as proficiency in English. None of the participants worked exclusively as NEv coordinator. NEv teams included health care professionals, students (undergraduate/graduate), professors, and civil servants from health departments. The data revealed high capacity to "acquire" and "assess" evidence, and low capacity to "adapt" and "apply" evidence. On average, three activities or products were developed yearly by each NEv, especially knowledge translation initiatives (systematic reviews and deliberative dialogues) and training for health care professionals, managers and undergraduate/graduate students. Five barrier categories were described: 1) financing, 2) network integration, 3) institutionalization of demands, 4) adaptive capacity, and 5) research communication skills to recommend actions at the local level. CONCLUSIONS: Trained human resources associated with academic and research institutions are available to support evidence-informed policies. However, the sustainability of NEvs depends on coordinated action to ensure the capacity to adapt and apply evidence.

OBJETIVO: Evaluar la capacidad, los arreglos organizativos y los obstáculos existentes para la aplicación de los núcleos de evidencia (NEv) de la Red de Políticas Informadas por Evidencia (EVIPNet) en Brasil. MÉTODOS: Se realizó un estudio descriptivo, analítico y exploratorio de casos múltiples, con un enfoque mixto. Los coordinadores de los NEv activos en el país respondieron a un instrumento dividido en tres partes: caracterización de la persona encuestada, evaluación de la capacidad de "adquirir, evaluar, adaptar y aplicar" evidencia (conocidas como 4A por su sigla en portugués) y temas de discusión abierta en los cuales se abordaron los arreglos organizativos y los obstáculos existentes para la aplicación de los NEv. RESULTADOS: Participaron en la investigación 5 NEv concentrados en la región Centro-Oeste; 73,3% tenían su sede en universidades y un 20% en secretarías estatales/municipales o en el Ministerio de Salud. Todos los coordinadores participantes tenían título de posgrado en sentido amplio o estricto y 80% afirmaron que tenían experiencia de 1 a 5 años en políticas informadas por evidencia (PIE) y que dominaban el inglés. Ningún coordinador trabajaba exclusivamente en el NEv. Los equipos incluían profesionales de salud, estudiantes (de grado/posgrado), profesores universitarios y empleados en comisión de servicio en las secretarías de salud. Se determinó que tenían gran capacidad para "adquirir" y "evaluar" y poca capacidad para "adaptar" y "aplicar" evidencias. En cuanto a actividades y productos, prevaleció la media de tres al año, con hincapié en los productos de traducción del conocimiento (la síntesis de la evidencia y los diálogos deliberantes) y la capacitación para profesionales de salud, gestores y alumnos de grado/posgrado. Se describieron cinco clases de obstáculos: 1) financiamiento, 2) integración de la red, 3) institucionalización de las demandas, 4) capacidad de adaptación y 5) habilidades de comunicación de las investigaciones para recomendar la adopción de medidas en el nivel local. CONCLUSIONES: Existen recursos humanos capacitados, vinculados a instituciones de investigación y enseñanza, para apoyar las PIE. Sin embargo, la sostenibilidad de los NEv depende de la adopción de medidas coordinadas para garantizar que existe la capacidad de adaptar y aplicar evidencia.
