Relationship between drug-related problems and health outcomes: a cross-sectional study among cardiovascular patients.
OBJECTIVE
To describe drug-related problems (DRPs) and expense problems (EPs) identified by a standardised community pharmacist-based medication review (MR) program among Swiss cardiovascular outpatients (56-75 years old) and to evaluate the need for collaborative pharmacy practice to achieve economic, clinical and humanistic outcomes.


METHODS
A pilot population of 85 cardiovascular outpatients who were customers of 14 community pharmacies (members of the pharmacieplus virtual chain) and insured with Groupe Mutuel health insurance.


METHODS
Cross-sectional study of a structured medication review program, conducted by 11 pharmacists in collaboration with 61 general practitioners (GPs), with patient interviews and access to medical data.


METHODS
Numbers and types of DRPs and EPs within the study population and odds ratios between them, as well as economic, clinical and humanistic outcomes.


RESULTS
Of the included patients, 91% had at least one DRP or EP. The odds ratios indicated that not being exposed to DRPs was associated with a higher chance of reaching the clinical target (OR: 3.4; IC95%:1.1-10.5; P = 0.01), of having a better physical quality of life than the median (OR: 2.5; IC95%: 0.9-7.3; P = 0.05) and having lower total health care costs (OR: 3.2; IC95%:1.1-9.8; P = 0.02).


CONCLUSIONS
This cross-sectional study shows that the control of cardiovascular risk factors, quality of life and healthcare costs are statistically related to the presence of DRPs detected by a community pharmacist-based MR program.
