Abstract
The World Health Organisation and International Society of Hypertension (WHO/ISH) cardiovascular disease (CVD)risk assessment charts have been implemented in many low- and middle-income countries as part of the WHO Package of Essential Non-Communicable Disease (PEN) Interventions for Primary Health Care in Low-Resource settings. Evaluation of the WHO/ISH cardiovascular risk charts and their use is a key priority and since they only exist in paper or PDF formats, we developed a simple R implementation of the charts for all epidemiological subregions of the world. The main strengths of this implementation are that it is built in a free, open-source, coding language with simple syntax, can be modified by the user, and can be used with a standard computer.
Highlights
Cardiovascular disease (CVD) is the leading cause of death worldwide, including in many low-and-middle income countries (LMIC)[1,2]
Through our experience collaborating with LMIC with the implementation of World Health Organisation (WHO) Package of Essential NCD (PEN), we identified a common need for an open-source tool to facilitate the implementation of WHO/International Society of Hypertension (ISH) risk charts and operational research of WHO PEN at a population level
Extraction of WHO/ISH cardiovascular risk charts All WHO/ISH risk charts were extracted by hand into a single comma delimited file (Dataset 1)
Summary
Cardiovascular disease (CVD) is the leading cause of death worldwide, including in many low-and-middle income countries (LMIC)[1,2]. In 2007 the WHO and the International Society of Hypertension (ISH) published the WHO/ISH CVD risk charts for all WHO epidemiological subregions of the world[4]. These charts are to be used as part of the WHO’s Package of Essential NCD (PEN) Interventions for Primary Health Care in Low-Resource Settings in jurisdictions that do not have their own population-derived risk assessment algorithms. While these charts are a good resource for many health systems, little is known about their validity[5]. It is important that jurisdictions that implement these charts conduct operational research and attempt to validate and optimise them for their setting
