Brief explanation of the Combined Approach Matrix (CAM) [7,8]

Overall process
Developed by the Global Forum for Health Research, CAM was to bring together economic and institutional dimensions into an analytical tool with the actors and factors that play a key role in health status of a population. It also aims to organise and present a large body of information that enters the priority setting process. This will help decision makers make rational choices in investment to produce greatest reduction in burden of disease.
How are participants identified?
Institutional approach involving: individual, household and community; health ministry and other health institutions; other sectors apart from health; and macroeconomic level actors.
How are research ideas identified
Five step process including measuring the disease burden, analysing determinants, getting present level of knowledge, evaluating cost and effectiveness, and present resource flows. For each main disease and risk factor, institutions and stakeholders with particular knowledge are brought together to provide information via workshops and brainstorming.
Each institution will feed into matrix the information at disposal, regarding a specific disease or factor; the matrix will reveal how little information is available in some areas which can then be candidates for research. Each participant determined the priority research topics based on CAM evidence, then grouping the topics and cutting down to establish the top priorities.
Scoring criteria
Criteria based on questions of what is a research priority in the context, and what is not known but should be.
Scoring options
N/A
Advantages
– Creates framework of information
– Identifies gaps in knowledge
– Facilitates comparisons between sectors
– Broad inclusion of actors
– 3D–CAM includes equity
Disadvantages – Difficult and time–consuming as involves multi–stage discussion
– Does not provide algorithm to establish and score research priorities therefore is not repeatable nor systematic
– Does not provide methodology for identifying participants
