Question
The following summarizes the costs of treatment of a disease based on four different antibiotics and associated health benefits (effectiveness). Effectiveness is measured as the percent of successful treatment of interventions. Use incremental cost-effectivenss ratios to select the antibiotics that are NOT dominated (see example 16.6). You may select more than one antibiotic. Antibiotic A - Cost of treating 100 patients $1450 - Effectiveness 74% Antibiotic B - Cost of treating 100 patients $1030 - Effectiveness 71% Antibiotic C - Cost of treating 100 patients $1340 - Effectiveness 77% Antibiotic D - Cost of treating 100 patients $1490 - Effectiveness 85% Antibiotic A Antibiotic B Antibiotic C Antibiotic D
Explanation / Answer
Cost effectiveness ratio = Cost of treating patients / Probability of that antibiotic
Cost effectiveness of Antibiotic A = $14.50 / 74% = 19.59
Cost effectiveness of Antibiotic B = $10.30 / 71% = 14.51
Cost effectiveness of Antibiotic C = $13.40 / 77% = 17.40
Cost effectiveness of Antibiotic D = $14.90 / 85% = 17.53
Thus, Antibiotic B is the most cost effective followed by Antibiotic C,D and A.
