Collaborative pharmacist prescribing in community heart failure clinics: a pre-post intervention comparison.
Article in International journal of clinical pharmacy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionGuideline-directed medical therapy (GDMT) improves outcomes in heart failure, yet many patients remain undertreated or are not titrated to optimal doses. International evidence shows pharmacist-led heart failure clinics improve GDMT prescribing and reduce hospitalisations, but data in Australian settings are limited.
aimTo evaluate whether incorporating a collaborative pharmacist medication prescribing model within a heart failure service improved optimisation of guideline-directed medical therapy (GDMT) in patients with heart failure and ejection fraction < 50% compared with pre-implementation usual care, and to evaluate impacts on service efficiency, hospitalisation, mortality, medication beliefs, and health-related quality of life.
methodAn interrupted time series analysis compared 12-month pre- and post-implementation periods following establishment of a collaborative pharmacist medication prescribing clinic across two community heart failure services. Primary outcomes were the proportion of patients optimised on GDMT at 90 days and at clinic discharge. Secondary outcomes included time between visits, monthly attendance, unscheduled hospitalisations, medication adherence and health related quality of life (HRQoL) assessed with the EuroQoL five-dimension five-level health status instrument visual analogue scale (EQ-VAS) and the Kansas City Cardiomyopathy Questionnaire (KCCQ-12).
resultsA total of 302 patients with ejection fraction < 50% were included, with 98 and 204 patients in the pre- and post-implementation cohort respectively. Overall, 285 patients (94.4%) had a left ventricular ejection fraction ≤ 40%, with similar proportions between cohorts (94.6% vs. 93.9%; p = 1.000). Optimisation of GDMT increased from 19.3% (n = 19) to 40.2% (n = 82) at 90 days (adjusted OR = 2.6, p = 0.001), and from 43.9% (n = 43) to 88.2% (n = 180) at discharge (adjusted OR = 13.2, p < 0.001). Median time between visits decreased from 49 to 28 days (p < 0.001), while mean monthly attendance increased from 9 to 16 (p < 0.001). HRQoL scores increased within the post-implementation group, measured by the KCCQ-12 (74.0 → 84.8, p < 0.001) and EQ-VAS (73.0 → 79.5, p = 0.004). Medication adherence remained high according to self-reported Medication Adherence Report Scale (MARS) scores. No change in hospitalisations or mortality was observed.
conclusionIntroducing a collaborative pharmacist medication prescribing clinic to usual care was associated with higher rates of GDMT optimisation and increased clinic throughput. These findings support the feasibility of collaborative prescribing models to facilitate GDMT optimisation within Australian health services.
