Aim: To study the consistency of opinions of participants in the treatment process of coronary heart disease with comorbid conditions with further analysis of the quality of pharmaceutical care and development of a strategy for improving interprofessional interaction of pharmacists in integrated care teams. Materials and Methods: The materials of the study were the results of a survey, conducted among the pharmacists of pharmaceutical stores, patients with coronary heart disease with comorbid conditions and doctors, according to the specified criteria for providing pharmaceutical care. The following research methods were used: analysis, deduction, induction, comparison, systematization, generalization, forecasting, statistical and bibliographic. Results: An intermediately satisfactory level of pharmaceutical care was determined. It was found that the implementation of pharmaceutical care requires the development of clinical competencies and communication skills of pharmacists with patients and the improvement of regulatory and legal support. Kendall’s consistency coefficient W = 0.85. Conclusions: A sufficiently high level of agreement of opinions (W = 0.85) of doctors, pharmacists and patients regarding the criteria for providing pharmaceutical care has been reliably confirmed. Directions for the development and improvement of mechanisms for providing pharmaceutical care have been identified. It is proposed to develop standards for providing pharmaceutical care to patients with coronary heart disease with comorbid conditions in accordance with the ESC/ AHA recommendations and taking into account the compatibility of medicines of different pharmacological groups used to cure the cardiovascular diseases.
