How was the research approach? We take a look at the methodology for the overall ranking.
The overall ranking is based on a weighted average of individual indicator rankings. A wide range of indicators was taken into consideration, grouped into three clusters: structure, process and outcome. This approach is based on Avedis Donabedian’s framework for evaluating the quality of health services. The study covers 35 countries, representing every region of the world and a broad spread in terms of population size and media coverage of their handling of the Covid-19 pandemic.
- Size of population
- Global coverage
- Media coverage on handling COVID-19 pandemic
The primary & secondary research built upon publicly available data from highly reputable sources such as the World Health Organization, the World Bank and the Johns Hopkins University and an expert survey.
Clustering healthcare system quality indicators
Contrary to others, the ranking builds on the established Donabedian model which clusters relevant healthcare system quality indicators into groups (structure, process and outcome) to compile an overall country ranking.
Weighted ranking of datapoints
The ranks per indicator as well as indicator group ranks and overall ranks were then calculated building upon a weighted consolidation of the individual ranks relative to the indicator importance.
- Structure: Weighed 25%
- Process: Weighed 25%
- Outcome: Weighed 50%
The following list shows the weight of the indicators in each category:
Factors that affect the contexts in which care is delivered (e.g. physical facility, equipment, social security system and human resources). Considered indicators are:
Sum of all actions that make up healthcare: diagnosis, treatment, preventive care, and patient education.
Contains all the effects of healthcare on patients or populations (e.g. changes to health status, behavior, patient satisfaction, health-related quality of life).
- The overall ranking is based on a weighted average of the ranks per indicator.
- The ranks of a country per indicator are multiplied by the according weights.
- Then the overall ranking is compiled by ranking the average scores of the results.
- In case of missing scores and ranks, the respective indicator is disregarded in the course of the average assessment.
