Estimates of Medication Expenditure for Ischemic Heart Disease Accompanying Chronic Obstructive Pulmonary Disease.

ABSTRACT

Ischemic heart disease (IHD) is a frequent accompaniment of chronic obstructive pulmonary disease (COPD). Co-occurrence of these two diseases is associated with many risk factors, difficulties in implementing appropriate therapies, numerous complications, and high spending for treatment. All these elements significantly reduce the quality of life of patients. The aim of this study was to estimate the expenditure for medications involved with IHD pharmacotherapy in the course of COPD. This retrospective study was based on the review of medical files of 57 patients, 27 women and 30 men, diagnosed with IHD, according to the severity classification, in the course of COPD which was staged according to the GOLD criteria. We found a considerable increase in per capita per year retail spending for drugs. The spending increased with the severity class of IHD; from 27.41 EUR in Class I to 142.30 EUR in Class IV. This spending did not include the treatment cost for the basic disease, i.e., COPD. A high individual cost burden was decreased by a discounting intervention of the National Health Fund. Despite a relatively high drug expenditure, we consider the treatment being cost-effective since we noticed a reduction in the classical risk factors for IHD, related to metabolic disturbances and lifestyle features, as soon as 2 months after treatment initiation. This study confirms that heart disease accompanying COPD is a frequent occurrence, generating high costs of treatment, which relates to the severity of this comorbidity.
