An Intersectoral Approach to Hypertension Care: Solutions for Improving Blood Pressure Control in São Paulo, Brazil.

BACKGROUND: Hypertension is the leading risk factor for cardiovascular diseases (CVDs) and a major public health issue worldwide. In Brazil, it affects approximately 52.5% of the adult population. We describe the solutions package and the impact of a population health initiative in São Paulo city, following the CARDIO4Cities approach for the management of cardiovascular risk. METHODS: Using a design thinking approach, interventions were developed with a coalition of local and international stakeholders to address needs of patients, healthcare professionals, and the health system. The resulting solution package was checked to comply with guidelines for non-communicable disease and hypertension management. Clinical impact was measured by extracting the hypertension cascade of care-monitored, diagnosis, treatment, and control-from medical records. RESULTS: Under the leadership of the municipal health authorities, nine solutions were piloted and scaled across the city. Solutions conform with local and international best-practices. Between October 2017 and December 2021, 11,406 patient records were analyzed. Results showed a 40% increase in monitored patients (patients with at least one blood pressure, BP, measurement); reduced proportions of patients diagnosed among those with available BP measurements (72%-53%) and treated among diagnosed (93%-85%); and an improvement in controlled patients among those receiving treatment (16%-27%). CONCLUSIONS: The solution package described in this study was correlated with increased BP control. The implementation methodology and results add to the body of real-world evidence supporting population health implementation science in Brazil and beyond.

Epidemiology of pediatric schistosomiasis in hard-to-reach areas and populations: A scoping review protocol.

Background: Schistosomiasis is a neglected tropical disease (NTD) that affects millions of people. Children are the most vulnerable group to developing overt disease. An estimated 779 million people are at risk of schistosomiasis and 50 million preschool-age children (PSAC) need treatment. PSAC are not currently targeted by national chemotherapy campaigns due to a lack of suitable pediatric formulations of praziquantel. The Pediatric Praziquantel Consortium has developed an orally dispersible praziquantel formulation (arpraziquantel) and is facilitating its adoption for schistosomiasis control by endemic countries through the ADOPT program - an implementation research program that paves the way for the large-scale delivery of the child-friendly formulation to treat schistosomiasis in preschool-aged children in endemic countries. A key challenge for comprehensive NTD control including schistosomiasis is reaching all at-risk populations, including those hard to reach. Main access barriers include geographic, social and economic conditions. Objective : This scoping literature review aims to document the epidemiology of schistosomiasis in children under 6 years of age living in hard-to-reach areas and populations. Methods : This review will adopt the five-stage scoping review process of identifying the research question, identifying relevant studies, study selection, charting data and collating, summarizing and reporting results. Electronic databases including Medline, Web of Science, Embase (Ovid), LILACS and African Journals OnLine (AJOL) will be searched for relevant articles. Two independent reviewers will screen identified articles using a two-stage approach of reviewing the title/abstract and then the full text of provisionally retained articles. Relevant literatures will be downloaded into EndNote X9 to maintain and manage citation and facilitate the overall review process. A meta-analysis will be conducted if indicated. Relevance : The results will provide insights into the burden of schistosomiasis among marginalized PSAC, aiming to produce evidence on the need for inclusion of this population when designing the expansion of preventive chemotherapy programs.
