Virtual Care Team Guided Management of Patients With Heart Failure During Hospitalization.

BACKGROUND: Scalable and safe approaches for heart failure guideline-directed medical therapy (GDMT) optimization are needed. OBJECTIVES: The authors assessed the safety and effectiveness of a virtual care team guided strategy on GDMT optimization in hospitalized patients with heart failure with reduced ejection fraction (HFrEF). METHODS: In a multicenter implementation trial, we allocated 252 hospital encounters in patients with left ventricular ejection fraction ≤40% to a virtual care team guided strategy (107 encounters among 83 patients) or usual care (145 encounters among 115 patients) across 3 centers in an integrated health system. In the virtual care team group, clinicians received up to 1 daily GDMT optimization suggestion from a physician-pharmacist team. The primary effectiveness outcome was in-hospital change in GDMT optimization score (+2 initiations, +1 dose up-titrations, -1 dose down-titrations, -2 discontinuations summed across classes). In-hospital safety outcomes were adjudicated by an independent clinical events committee. RESULTS: Among 252 encounters, the mean age was 69 ± 14 years, 85 (34%) were women, 35 (14%) were Black, and 43 (17%) were Hispanic. The virtual care team strategy significantly improved GDMT optimization scores vs usual care (adjusted difference: +1.2; 95% CI: 0.7-1.8; P < 0.001). New initiations (44% vs 23%; absolute difference: +21%; P = 0.001) and net intensifications (44% vs 24%; absolute difference: +20%; P = 0.002) during hospitalization were higher in the virtual care team group, translating to a number needed to intervene of 5 encounters. Overall, 23 (21%) in the virtual care team group and 40 (28%) in usual care experienced 1 or more adverse events (P = 0.30). Acute kidney injury, bradycardia, hypotension, hyperkalemia, and hospital length of stay were similar between groups. CONCLUSIONS: Among patients hospitalized with HFrEF, a virtual care team guided strategy for GDMT optimization was safe and improved GDMT across multiple hospitals in an integrated health system. Virtual teams represent a centralized and scalable approach to optimize GDMT.

Rehospitalization of Patients with Advanced Heart Failure Receiving Continuous, Palliative Dobutamine or Milrinone.

This study aims to determine the incidence of all-cause hospitalization in patients with advanced heart failure (AHF) receiving ambulatory continuous, intravenous dobutamine versus milrinone for palliative intent. Despite medical optimization, patients with AHF develop refractory symptoms, resulting in frequent hospitalizations. Previous trials precede modern care standards. Data regarding inotrope choice in palliation are limited. This retrospective analysis included 222 patients with AHF and reduced left ventricular ejection fraction discharged on palliative dobutamine (n = 135) or milrinone (n = 87). The primary outcome was incidence of all-cause rehospitalization compared by treatment type. Demographics between groups were similar. In the milrinone arm, more patients were discharged on ß blockers (62% vs 22%; p <0.001); fewer patients were discharged to hospice (6% vs 30%). More patients in the milrinone arm than in the dobutamine arm were rehospitalized within 180 days (80% vs 59%; p = 0.002); when patients discharged to hospice were excluded, this difference was no longer significant (83% vs 74%; p = 0.14). Overall mortality was lower in the milrinone arm (63% vs 80%; p = 0.006); survival was longer (median: 228 vs 52 days; p <0.001). Patients receiving milrinone spent more days alive and out of the hospital at 90 days after discharge (70 vs 37 days; p <0.001). In conclusion, in patients with AHF receiving palliative inotropes, there was no difference in rehospitalization when excluding patients discharged to hospice. Milrinone use was associated with decreased mortality and longer survival. Agent selection must closely align with the patient's disease trajectory.

Time to clinical response in sepsis associated with an algorithm for blood-culture pathogen identification using matrix-assisted laser desorption ionization time-of-flight mass spectroscopy.

PURPOSE: Antimicrobial stewardship programs (ASPs) can be aided by using rapid diagnostics (RDT). However, there are limited data evaluating the impact of ASPs and RDT on sepsis outcomes in the setting of the new Sepsis-3 guidelines. This study evaluates the impact of a low-resource method for ASPs with RDT on sepsis outcomes. METHODS: This was a prospective, quasi-experimental study with a retrospective double pretest. Patients ≥ 18 years old with sepsis and concurrent bacteremia or fungemia were included; patients who were pregnant, had polymicrobial septicemia or who were transferred from an outside hospital were excluded. In the first pretest (O1), polymerase chain reaction was used to identify Staphylococcal species from positive blood cultures, and traditional laboratory techniques were used to identify other species. Matrix-assisted laser desorption ionization time-of-flight mass spectroscopy and FilmArray were implemented in the second pretest (O2), and twice daily blood culture review was implemented in the posttest (O3). RESULTS: A total of 394 patients (157 in O1, 176 in O2, 61 in O3) were enrolled. Clinical response was 73.2%, 83.5%, and 88.5% in O1, O2, and O3, respectively, p = 0.013. By Cox regression, the O3 was associated with improved time to clinical response (hazard ratio, 1.388; 95% confidence interval, 1.004-1.919) as compared with O1. Mortality, hospital length of stay, and intensive care unit length of stay were unchanged between groups. CONCLUSION: Twice-daily blood culture review may be useful for implementing rapid diagnostics within low-resource ASPs. Further research is needed to identify the optimal method of blood culture follow-up within low-resource settings.
