Comparison of two models of frailty for the prediction of mortality in Brazilian community-dwelling older adults: the fibra study

Prevalence of frailty is significant in Latin America. However, no previous study evaluated mortality prediction using the two most used frailty models in Brazil. Objectives The aim of the present study was to compare the frailty phenotype and the frailty index with regard to accuracy in the prediction of mortality among community-dwelling older adults. Methods A cohort study was conducted involving 674 older adults. Thirty-five variables (signs, symptoms, chronic diseases and disabilities) were used for the construction of the frailty index (FI). The frailty phenotype index (FPI) was defined based on the criteria proposed in the Cardiovascular Health Study. Periodic verifications were performed in the databank of the Mortality Information System. Cox regression was used to estimate the relative risk (RR) of mortality and Kaplan-Meier survival curves were used in the analysis. Results The prevalence of frailty was greater based using the FI (16.3%) compared to the FPI (5.34%). Older adults classified as frail by the FPI had a greater risk of death (RR: 10.03; 95% CI: 4.43-22.74) that those classified as frail by the FI (RR: 0.87; 95% CI: 0.25-3.00). The lowest survival rate was found in the group of older adults classified as frail based on the FPI and classified as pre-frail and robust based on the FI. Conclusion The FPI demonstrated greater accuracy in predicting the risk of mortality among Brazilian older adults than the FI. The validation of frailty measures is fundamental to the identification of older adults who are more vulnerable to adverse health events.231010041010CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQSem informaçã

Recommendations for developing effective and safe paediatric and congenital heart disease services in low-income and middle-income countries: a public health framework

The global burden of paediatric and congenital heart disease (PCHD) is substantial. We propose a novel public health framework with recommendations for developing effective and safe PCHD services in low-income and middle-income countries (LMICs). This framework was created by the Global Initiative for Children’s Surgery Cardiac Surgery working group in collaboration with a group of international rexperts in providing paediatric and congenital cardiac care to patients with CHD and rheumatic heart disease (RHD) in LMICs. Effective and safe PCHD care is inaccessible to many, and there is no consensus on the best approaches to provide meaningful access in resource-limited settings, where it is often needed the most. Considering the high inequity in access to care for CHD and RHD, we aimed to create an actionable framework for health practitioners, policy makers and patients that supports treatment and prevention. It was formulated based on rigorous evaluation of available guidelines and standards of care and builds on a consensus process about the competencies needed at each step of the care continuum. We recommend a tier-based framework for PCHD care integrated within existing health systems. Each level of care is expected to meet minimum benchmarks and ensure high-quality and family centred care. We propose that cardiac surgery capabilities should only be developed at the more advanced levels on hospitals that have an established foundation of cardiology and cardiac surgery services, including screening, diagnostics, inpatient and outpatient care, postoperative care and cardiac catheterisation. This approach requires a quality control system and close collaboration between the different levels of care to facilitate the journey and care of every child with heart disease. This effort was designed to guide readers and leaders in taking action, strengthening capacity, evaluating impact, advancing policy and engaging in partnerships to guide facilities providing PCHD care in LMICs
