AbstractThe purpose of this research was to evaluate the strategy of the military health service (MHS) to improve asthma outcomes through the use of clinical practice guidelines (CPGs). Outcomes were evaluated at the patient level and included inpatient/outpatient visits, prescriptions dispensed, number of exacerbations, number of beddays and direct cost of therapy. In addition, provider compliance to CPG recommendations was evaluated by measuring the proportion of subjects dispensed long-acting controller medications. A nonrandomized control-group before-after design with retrospective matched-pair DoD data was used for this research. The intervention used in this research was the formal asthma CPG-use process implemented by the Army in September of 2000. Compared to baseline measures, all outcomes improved significantly (p < 0.05) in the after period for both the subjects exposed, and not exposed, to the CPG-use process. Other than the improvement noted in the number of asthma exacerbations, which was greater in the exposed group than the non-exposed group (p < 0.001), there was no other difference between groups in the amount that outcomes improved. The proportion of subjects prescribed long-term controller medications increased significantly for subjects exposed to the CPG-use process (0.30 to 0.66, p < 0.001), and for those not exposed to the CPG-use process (0.30 to 0.66, p < 0.001). Although the findings of this research suggested that a formal CPG-use process to standardize asthma therapy was associated with decreased costs, this was not supported by results regarding the clinical outcomes. To further evaluate the effect of asthma CPGs on economic and clinical outcomes, additional research is needed.
