ABSTRACT

OBJECTIVE: Patient decision aids are important tools for facilitating balanced, evidence-based decision making. However, the potential of decision aids to lower health care utilization and costs is uncertain; few studies have investigated the cost-effectiveness of decision aids that change patient behavior. Using an example of a decision aid for colorectal cancer screening, we provide a framework for analyzing the cost-effectiveness of decision aids. METHODS: A decision-analytic model with two strategies (decision aid or no decision aid) was used to calculate expected costs in U.S. dollars and benefits measured in life-years saved (LYS). Data from a systematic review of ten studies about decision aid effectiveness was used to calculate the percentage increase in the number of people choosing screening instead of no screening. We then calculated the incremental cost per LYS with the use of the decision aid. RESULTS: The no decision aid strategy had an expected cost of $3023 and yielded 18.19 LYS. The decision aid strategy cost $3249 and yielded 18.20 LYS. The incremental cost-effectiveness ratio for the decision aid strategy was $36,126 per LYS. Results were sensitive to the cost of the decision aid and the percentage change in behavior caused by the decision aid. CONCLUSIONS: This study provides proof-of-concept evidence for future studies examining the cost-effectiveness of decision aids. The results suggest that decision aids can be beneficial and cost-effective.

ABSTRACT

BACKGROUND: Although smoking-cessation interventions typically focus directly on patients, this paper conducts an economic evaluation of a novel smoking-cessation intervention focused on training physicians and/or pharmacists to use counseling techniques that would decrease smoking rates at a reasonable cost. PURPOSE: To evaluate the cost-effectiveness of interventions that train physicians and/or pharmacists to counsel their patients on smoking-cessation techniques. METHODS: Using decision-analytic modeling, we compared four strategies for smoking-cessation counseling education: training only physicians, training only pharmacists, training both physicians and pharmacists (synergy strategy), and training neither physicians nor pharmacists (i.e., no specialized training, which is the usual practice). Short-term outcomes were based on results from a clinical trial conducted in 16 communities across the Houston area; long-term outcomes were calculated from epidemiological data. Short-term outcomes were measured using the cost per quit, and long-term outcomes were measured using the cost per quality-adjusted life-year (QALY). Cost data were taken from institutional sources; both costs and QALYs were discounted at 3%. RESULTS: Training both physicians and pharmacists added 0.09 QALY for 45-year-old men. However, for 45-year-old women, the discounted quality-adjusted life expectancy only increased by 0.01 QALY when comparing the synergy strategy to no intervention. The incremental cost-effectiveness ratio (ICER) of the synergy strategy with respect to the non-intervention strategy was US$868/QALY for 45-year-old men and US$8953/QALY for 45-year-old women. The results were highly sensitive to the quit rates and community size. CONCLUSION: Synergistic educational training for physicians and pharmacists could be a cost-effective method for smoking cessation in the community.
