Improving adjuvant endocrine therapy initiation among patients with breast cancer: a nurse-led, culturally sensitive pilot study.

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
purposeUp to 30% of patients with hormone receptor-positive (HR +) breast cancer do not start adjuvant endocrine therapy (AET) as prescribed. AET non-initiation is associated with increased recurrence and decreased survival. We conducted a single-arm, open-pilot study to assess the feasibility and acceptability of a nurse-led, culturally sensitive intervention ('INITIATE') to optimize AET initiation.
methodsFrom 9/2022 to 8/2024, we recruited 35 patients with stage I-IIIB, HR + breast cancer who delayed or reported hesitancy to start AET. INITIATE included two virtual sessions delivered in English or Spanish with an oncology nurse. Feasibility was defined by enrollment rates (> 50% eligible patients), intervention attendance (≥ 70% of patients attending one of two sessions), and retention (> 70% completing the 3-month questionnaire). At baseline, 1 month, and 3 months post-baseline, patients self-reported sociodemographics, AET initiation, intervention acceptability (Client Satisfaction Questionnaire-3), and other psychosocial outcomes. We conducted semi-structured, qualitative exit interviews to gather additional feedback. We computed descriptive statistics for the quantitative outcomes and conducted a rapid qualitative analysis of the interview data.
resultsWe enrolled 45.5% (35/77) of eligible patients; 82.9% (29/35) attended at least one intervention session, and 77.1% (27/35) completed the 3-month assessment. Most patients (68.6%) were White, and 37.1% identified as a racial or ethnic minority. Qualitatively, patients reported that INITIATE helped them understand the importance of taking AET and improved their coping skills. Ninety-six percent reported high acceptability, and 88.9% started their AET by three months post-baseline.
conclusionINITIATE is mostly feasible and acceptable and demonstrates promise for promoting AET initiation among patients with HR + breast cancer.
