[Substantiation of the model of clinical and economic efficiency evaluation of prevention, treatment, and dispenserization of the patients with comorbidity. The example of patients with arterial hypertension and duodenitis].

OBJECTIVE: Introduction: Evidence based medicine requires reliant estimators of medical programs efficiency both in clinical and economical dimensions. It necessitates the substantiation of evaluation of assessment tools on the ground of clinical and economic theory. Developed model has advantage of direct link with classical economic analyses such as costutility, cost-efficiency, and cost-benefit. The aim was to substantiate the model of clinical and economic efficiency evaluation of medical program with allowance for comorbidity.

PATIENTS AND METHODS: Materials and methods: Model developed on the premises of Zweifel & Breyer [1, 2], theoretical foundation based upon classical theory of moral hazard and consumer utility. Model describes equilibrium of patient's decision on the volume of medical services to consume.

RESULTS: Results: We delivered the model development and equilibrium examination. Transformation of equilibrium model to cost-utility, cost-efficiency, and cost-benefit models displayed. There was also demonstrated the allowance for comorbidity with example of patients with duodenitis and arterial hypertension.

CONCLUSION: Conclusions: Proffered model based on theoretical ground of moral hazard and consumer utility. There is a direct linkage with cost-utility, cost-efficiency, and cost-benefit models. For the purpose of better cognition of practical applicability we introduced model in the context of dispenserization of the patients with duodenitis and arterial hypertension.
