Abstract: The ability to assign patients to the most appropriate program of intervention would improve patient outcomes and reduce health care costs. This paper evaluates specific potentials of triaging patients into various combinations of health education treatments. Blood pressure improvement among hypertensive patients was measured and the associated treatment cost and savings were compared. Triaging rules were formed empirically from the relationship between patient characteristics selected before the study was conducted and their achieved blood pressure control within each combination of interventions. Patients randomly assigned to seven combinations of three interventions were studied in contrast to patients in a randomized control group. A combination of all three interventions was the most effective program for the undifferentiated (random) patient population, achieving a 49% increase over 18 months in patients with blood pressure under control. By triaging, 51-91% increases in patients with controlled blood pressure were achieved. Educational history of the patients which is a fairly reliable measure was the most efficient triaging variable, showing a 91% increase in patients with blood pressure under control and a relative cost saving of about 400%.
