Frequency distribution of health disorders in primary care-its consistency and meaning for diagnostics and nomenclature.

RN Braun observed that frequencies of health disorders in general practice are so consistent that he called his discovery "Case Distribution Law". Our study compares morbidity data from methodologically similar surveys in primary care practices over a period of fifty years. Frequency ranks were determined for each observation period and the first 150 ranks were compared with Spearman's correlation coefficients.

Family practices provide medical care for the majority of health problems. This already highlights the importance of primary health care with respect to quantity. A detailed five-year survey of cases in two rural practices gives insight into everyday practice.
