Abstract Objectives Research in general practice demands it-tools which give the practitioner trusty results. Medrave 4 is a program designed for extraction of data from all areas of the health record. We wanted to do research on the database in a health center, but found no proof of the quality of the data extracted by Medrave 4. Today the database contains about 40,000 records. In this study we wanted to examine if the program could extract correct data. Results From the database 20 records were randomly selected from five different time periods, making a total of 100 records. 14 records did not meet the inclusion criteria, resulting in 86 records included in the study. In phase one these variables were registered manually from the records: Age, gender, systolic and diastolic blood pressure (from free text) and six different laboratory tests. In phase two, Medrave 4 extracted the same variables from the same records. Medrave 4 found correct systolic and diastolic blood pressure values in 79 records (92%). The laboratory results were extracted correct in all 86 records (100%). We conclude that Medrave 4 can be a useful tool in quantifying the work of general practitioners.
