The diagnostic content of family practice: 50 most common diagnoses recorded in the WAMI community practices.

Because there are several methodological deficiencies in previously published studies, a prospective study was carried out of the 50 most common diagnoses of community-based family practices in the Pacific Northwest. Age and sex of patients and reliability of data were controlled. The data reported show reasonable concordance with other published accounts for 10 most common diagnostic categories. For less frequent diagnoses, however, high variability in rank order is the rule, both within this study and by comparison with other studies. This suggests that the diagnostic content of family practice is far from universal and that diagnostic idiosyncrasies of physicians, regional differences in rates of disease, practice style, and as yet other unexplained factors may significantly influence the diagnostic content of family practice.
