Implementation and evaluation of specialist heart failure pharmacist prescribing clinics.

Background: Medications form the basis of treatment for heart failure (HF) and adherence is crucial as untreated HF has a mortality of greater than 30%. As such, specialist HF pharmacists with expertise in prescribing and promoting adherence have become an integral part of the wider HF multidisciplinary team (MDT).

Aim: To implement specialist HF pharmacist prescribing clinics and evaluate their impact.

Setting: An integrated HF team at a tertiary London hospital.

Development: The clinic was initially developed to facilitate the introduction of sacubitril-valsartan evolving to 6 dedicated clinics/week.

Implementation: A dedicated electronic referral pathway was created to channel referrals to the specialist clinic, and referral criteria expanded to all patients requiring optimisation of medical therapy.

Evaluation: Data were retrospectively collected for patients with heart failure with reduced ejection fraction seen in the HF pharmacist clinic between September 2021 and July 2022. Overall, 114 patients were seen (mean age 66 years, 78 male). The mean time to medication optimisation was 3 months (averaging 1 appointment/month). The number on optimised doses of guideline-directed medical therapy, increased significantly from 8% at first appointment to 76% on discharge (p < 0.001). The HF pharmacists reviewed all medications and optimised non-HF medications for 17.5% (n = 20) of patients.

Conclusion: HF pharmacists can optimise patients' HF and non-HF medical therapy typically within 3 months. By reviewing all prescribed medications, HF pharmacists provide a holistic review of all medications. They can play a vital role in addressing the underutilisation of HF medical therapy and thereby improving patient outcomes.
