Traditionally, meta-analysis methods have been developed and used to combine data from several independent clinical trials as well as observational studies, but have not been as widely used in survey research. This paper describes the steps in conducting such a meta-analysis of surveys, to obtain a single summary estimate from a combination of individual-level and summary data. The methods are applied in the context of a project aimed at obtaining an estimate of the prevalence of use of electronic health records.
