The Ambulatory Cardiac Triage, Intervention, and Education (ACTIVE) infusion unit is an outpatient center that aims to provide heart failure (HF) patients with comprehensive multidisciplinary interventions.

To describe the patient population served in ACTIVE and to document the prevalence of comorbidities and drug therapy-related issues (DRIs) in order to define the most effective role of a pharmacist in the unit.

Patients who have been interviewed by a pharmacist in ACTIVE were included. Comprehensive medical and medication profile reviews were performed. Patient comorbidities were documented, and DRIs were classified.

Sixty patients were included. Most prevalent cardiac comorbidities included hypertension (73%) and hyperlipidemia (62%). Top 3 noncardiac comorbidities included chronic kidney disease (60%), diabetes (50%), and obesity (35%). The prevalence of DRI was reported as follows: (1) needs additional/alternative therapy (untreated indication [37] or suboptimal therapeutic choice [46]), (2) wrong drug (major drug–drug interaction [90], contraindication [11], or duplicate therapy [1]), (3) suboptimal dosing (17), (4) dose exceeds recommended maximum (9), and (5) adverse drug reaction (93). In 63 (22%) of the DRIs, a pharmacist made recommendations to modify the regimen.

The prevalence of DRI is high even among HF patients managed in a subspecialty cardiovascular practice. Pharmacists in this setting play a vital role in more effectively resolving DRI.
