An early discharge strategy using subcutaneous furosemide delivered via a wearable minipump resulted in 4.0 more days alive and out of hospital at 30 days compared with usual care in patients hospitalized for heart failure requiring ongoing parenteral diuretics.
Key Findings
Results
The early discharge strategy resulted in significantly more days alive and out of hospital (DAOH) at 30 days compared with usual care.
The early discharge group had 4.0 more DAOH at 30 days (95% CI: 2.1-5.8 days; P < 0.001)
172 patients were randomized: 92 to early discharge and 80 to usual care
The trial was a multicenter, open-label, randomized, active-controlled trial conducted in the United Kingdom
Both groups received a 2-week clinic review as part of follow-up
Results
Patients in the early discharge group had significantly shorter index hospitalizations.
Index hospitalization was shorter by a mean of 5.5 days (95% CI: 7.4-3.6 days; P < 0.001)
Patients were hospitalized for heart failure requiring ongoing parenteral diuretics at the time of randomization
The early discharge group received pH-neutral subcutaneous furosemide via a wearable, patient-operated minipump
Postdischarge care included a review every 3 days while receiving subcutaneous furosemide
Results
The benefit in DAOH was sustained at 60 days despite more heart failure readmissions in the early discharge group.
The difference in DAOH at 60 days was 4.2 days (95% CI: 0.9-7.6 days)
More heart failure readmissions occurred in the early discharge group: 13 (14%) patients vs 5 (6%) patients in usual care (OR: 2.45; 95% CI: 0.81-7.43)
The confidence interval for the odds ratio of readmission crossed 1.0, indicating the difference in readmissions was not statistically significant at conventional thresholds
Results
Serious adverse events occurred at similar rates in both groups, and device-related problems were infrequent and non-serious.
Serious adverse events occurred in 25% of early discharge patients and 23% of usual care patients
Device-related problems occurred with 3% of minipump placements
None of the device-related problems were serious
The minipump was described as patient-operated, delivering pH-neutral subcutaneous furosemide
Background
The study enrolled patients hospitalized for heart failure who required ongoing parenteral diuretic therapy, a population contributing to prolonged and costly inpatient stays.
Prolonged intravenous diuretic therapy was identified as contributing to costs and risks associated with inpatient care
Eligibility required ongoing parenteral diuretics at the time of randomization
The trial is registered as NCT05419115 (SUBCUT-HF II: Use of a Novel SUBCUTaneous Preparation of Furosemide to Facilitate Early Supported Discharge of Patients With Heart Failure)
The study was conducted across multiple centers in the United Kingdom
What This Means
This research suggests that patients hospitalized for heart failure who need ongoing intravenous diuretics (water pills given through a vein) can be safely sent home earlier if they are switched to a wearable pump that delivers furosemide under the skin. In this UK-based trial of 172 patients, those discharged early with the subcutaneous pump spent about 4 more days alive and out of the hospital over the following 30 days compared to patients who stayed in the hospital for standard care. Their hospital stays were also about 5.5 days shorter on average.
The benefit in time spent at home persisted at 60 days, even though slightly more patients in the early discharge group were readmitted for heart failure (14% vs 6%). The device itself was generally safe — problems with the pump occurred in only 3% of placements and none were considered serious. Rates of serious adverse events were similar between the two groups (25% vs 23%).
This research suggests that a supported early discharge model — where patients manage their own subcutaneous furosemide pump at home and are checked in on every few days — could meaningfully reduce the time heart failure patients spend in the hospital without substantially increasing safety risks. This approach could have implications for hospital capacity, healthcare costs, and patient quality of life, though the finding of more readmissions in the early discharge group warrants further study.
