A problem-based approach which can be utilized in general practice for 'diagnosis and treatment' is described. The various related phases and probable components have been defined, starting with problem sensing, problem detection, problem description and then proceeding to problem assessment and problem-oriented intervention and evaluation. This approach is empirical, patient-centered, geared to general practice, easily acquired and may well have utility in other fields of medicine. Investigation of its effectiveness and efficiency as well as its ability to be taught is needed.
