Comparison of Health Examination Survey Methods in Brazil, Chile, Colombia, Mexico, England, Scotland, and the United States.

ABSTRACT: Comparability of population surveys across countries is key to appraising trends in population health. Achieving this requires deep understanding of the methods used in these surveys to examine the extent to which the measurements are comparable. In this study, we obtained detailed protocols of 8 nationally representative surveys from 2007-2013 from Brazil, Chile, Colombia, Mexico, the United Kingdom (England and Scotland), and the United States-countries that that differ in economic and inequity indicators. Data were collected on sampling frame, sample selection procedures, recruitment, data collection methods, content of interview and examination modules, and measurement protocols. We also assessed their adherence to the World Health Organization's "STEPwise Approach to Surveillance" framework for population health surveys. The surveys, which included half a million participants, were highly comparable on sampling methodology, survey questions, and anthropometric measurements. Heterogeneity was found for physical activity questionnaires and biological samples collection. The common age range included by the surveys was adults aged 18-64 years. The methods used in these surveys were similar enough to enable comparative analyses of the data across the 7 countries. This comparability is crucial in assessing and comparing national and subgroup population health, and to assisting the transfer of research and policy knowledge across countries.

Project description:ObjectivesValue-based healthcare (VBHC) is a health system reform gradually being implemented in health systems worldwide. A previous national-level survey has shown that Latin American countries were in the early stages of alignment with VBHC. Data at the healthcare provider organisations (HPOs) level are lacking. This study aim was to investigate how HPOs in five Latin American countries are implementing VBHC.DesignMixed-methods research was conducted using online questionnaire, semistructured interviews based on selected elements of the value agenda (from December 2018 to June 2020), analyses of aggregated data and documents. Qualitative analysis was performed using NVivo QSR International, 1.6.1 (4830). Quantitative analysis used Fisher's exact test. Univariate analysis was used to compare organisations in relation to the implementation of VBHC initiatives. A p≤0.05 was considered significant.ParticipantsTop and middle-level executives from 70 HPOs from Argentina, Brazil, Chile, Colombia and Mexico.ResultsThe definition of VBHC varied across participating organisations. Although the value equation had been cited by 24% of participants, its composition differed in most case from the original Equation. Most VBHC initiatives were related to care delivery organisation (56.9%) and outcomes measurement (22.4%) but in most cases, integrated practice unit features had not been fully developed and outcome data was not used to guide improvement. Information, stakeholders buy-in, compensation and fragmented care delivery were the most cited challenges to VBHC implementation. Fee-for-service predominated, although one-third of organisations were experimenting with alternative payment models.ConclusionsA wide variation in the definition and level of VBHC implementation existed across organisations. Our finding suggests investments in information systems and on education of key stakeholders will be key to foster VBHC implementation in the region. Further research is needed to identify successful implementation cases that may serve as regional benchmark for other Latin American organisations advancing with VBHC.
