Objectives.— To develop determine the accuracy utility assessment tool (CHAT). CHAT was designed identify all major primary disorders, distinguish from types, recognize medication overuse. Methods.— using expert systems approach diagnosis, initial branch points determined by frequency duration. Appropriate clinical criteria presented relevant brief longer-lasting headaches. posted on web site Microsoft active server pages SQL-server database server. convenience sample patients who adult urgent care department headache, in family practice waiting room, were solicited participate. Those completed on-line questionnaire contacted interview. Results.— One hundred thirty-five 117 interview. correctly identified 35/35 (100%) 42/49 (85.7%) transformed also 11/11 tension-type 2/2 1/1 cluster headache.

Of 29 PCP confirmed diagnosis migraine, 25 made follow-up appointment, diagnosed 19, initiated migraine-specific therapy prophylaxis 17. Conclusion.— described system displays high other including syndromes overuse. As part disease management program, led receiving appropriate diagnoses therapy. Limitations include patient willingness utilize introducing such process into culture medical care, difficult distinction
