The foundations of the WHO World Health examination Survey Plus (WHS+) are grounded in methods tested in numerous countries over many years. Yet this robust methodology remains agile, with an eye to innovations in tools, technology, and technical exchange that contribute to building a sustainable mechanism to periodically monitor health and evaluate health systems in Member States. Health information systems that include these surveys would find interoperability of data across countries, meaning that analyses could also be aggregated to the regional and global levels. National Statistical Organizations (NSOs) have untapped potential to improve country-owned information systems for health and will be integral to WHS+ implementation in many countries. Countries would be supported to execute a regular system of surveys informed by country priorities and using global standards. All data collected for or coordinated with WHS+ will be open, with clear standards on timeframe of posting of data. The WHS+ will be a nationally representative household health examination survey that uses a modular approach. It will be implemented as a face-to-face interview and examination within households. Interviews will be supported by Computer Assisted Personal Interview (CAPI) methods. The development of the survey will ensure relevance for country-specific needs, while also ensuring cross-national comparability of data. The WHS+ survey tools will be multi-topic (covering the full range of health priorities, tailored to country priorities), multi-mode (household, mobile, web, mixed), and multi-platform (available as stand-alone tools or building on and being incorporated into existing surveys). The surveys lay the foundation for the longitudinal study of intergenerational patterns in health outcomes and determinants. The WHS+ will use a robust methodology with an intelligent blend of tools, technology, and technical exchange to build a sustainable system to periodically monitor UHC, including service coverage, household health expenditure and health care utilisation, and evaluate health systems at national, global, and regional levels. Procedures and protocols would be developed in close collaboration with countries to link survey data with facility and administrative data sources, providing inputs for a strong public health information system. Broadly, the WHS+ platform will support countries, which will decide whether to collect some or all of: A full household survey with examination, covering a broad range of health topics; Selected topic surveys, either household, facility, or phone; Mobile phone surveys; Web panels and surveys, using cutting-edge methodology where available and appropriate. The WHS+ platform will also host surveys done either directly by the WHS+ process, or, for those willing to participate, in other survey efforts. WHS+ has been piloted in Cambodia, Bangladesh, Ghana and Nepal in 2023.
