Sources and processing

This data is based on the following sources

The Global Atlas of Medical Devices (GAMD) provides global, regional, and country data on the availability of:

  • National policy on health technology
  • Regulation of medical devices
  • Health technology assessment national unit
  • Health technology management
  • Use of medical devices nomenclature system
  • National lists of priority medical devices
  • High-cost medical equipment

The GAMD also identifies that Member States designate a focal point for health technologies and medical devices. Each Member State designates a focal point in the ministry of health with the survey responses.

The WHO Baseline Country Survey on Medical Devices was developed in 2009. The aim was to determine the health technology areas that required support in countries and regions. It was launched in February 2010. In 2013, it was updated and re-launched as the Global Atlas of Medical Devices. The GAMD was updated in 2017, and the 2022 update is under development.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
