Brief summary
The multicenter SUBCUT-HF II randomized trial of 172 hospitalized heart failure patients demonstrated that early discharge using a wearable subcutaneous furosemide minipump achieved 4.0 more days alive and out of hospital at 30 days compared with standard inpatient care.
What NurseJet pulled from the source
Patients hospitalized with decompensated heart failure frequently endure prolonged inpatient admissions solely to finish intravenous loop diuretic titration. In the multicenter, open-label, active-controlled SUBCUT-HF II randomized trial (NCT05419115) conducted across the United Kingdom, 172 patients hospitalized for heart failure who required continued parenteral diuretic therapy were randomized to an early supported discharge strategy (n=92) or usual inpatient care (n=80). The early discharge cohort received a novel pH-neutral formulation of subcutaneous furosemide administered via a wearable, patient-operated minipump, supported by outpatient clinical reviews every 3 days during active infusion, alongside a 2-week follow-up for both arms. The primary endpoint of days alive and out of hospital (DAOH) at 30 days was significantly higher in the early discharge arm (4.0 more days, 95% CI: 2.1–5.8 days; p < 0.001). Mean index hospital stay was shortened by 5.5 days (95% CI: 3.6–7.4 days; p < 0.001). This DAOH benefit was sustained through 60 days (4.2 days, 95% CI: 0.9–7.6 days), despite non-statistically significant higher heart failure readmissions in the early discharge group (14% [n=13] vs 6% [n=5]; OR: 2.45, 95% CI: 0.81–7.43). Serious adverse events occurred in 25% vs 23% of participants, and device issues arose in 3% of placements without serious sequelae.
Why this matters for nurses
Cardiology and telemetry nurses spend extensive time coordinating intravenous diuretic administration, monitoring fluid balances, and planning discharge for heart failure patients who are otherwise clinically stable. Wearable subcutaneous infusion technology enables safe, out-of-hospital decongestion, liberating acute hospital beds and improving patient quality of life, but requires specialized nurse education on pump operation, infusion site care, and vigilant outpatient symptom surveillance.
Bedside takeaway
In the 172-patient SUBCUT-HF II trial, early discharge with a wearable subcutaneous furosemide minipump yielded 4.0 more days alive and out of hospital at 30 days and shortened index hospital stay by 5.5 days.
Key takeaways
- Multicenter UK randomized controlled trial (SUBCUT-HF II) evaluated 172 patients hospitalized with heart failure requiring ongoing parenteral diuresis.
- Early discharge with a wearable subcutaneous furosemide minipump yielded 4.0 more days alive and out of hospital at 30 days (p < 0.001).
- Mean length of index hospital stay decreased by 5.5 days (95% CI: 3.6–7.4 days, p < 0.001) in the subcutaneous minipump cohort.
- Clinical benefits persisted at 60 days (4.2 additional DAOH), with comparable serious adverse event rates (25% vs 23%).
- Device-related technical issues were observed in only 3% of placements, confirming the mechanical feasibility of outpatient wearable infusion.
Practice implications
- Educate heart failure patients on subcutaneous minipump placement, needle insertion site inspection for local erythema or leakage, daily weights, and symptom red flags; coordinate close outpatient follow-up checks every 3 days during active subcutaneous loop diuretic titration.
Limitations & cautions
- Open-label trial design; trend toward higher 30-day readmissions (14% vs 6%, OR 2.45) warrants close outpatient monitoring systems; conducted within UK National Health Service infrastructure.
