The comparative effectiveness of 2 transitions of care programs for improving health status and reducing readmissions among patients hospitalized with heart failure is unknown. To compare the effectiveness adding mobile integrated health (MIH) to a transitions of care coordinator for improving health status and reducing 30-day all-cause readmissions among patients discharged after heart failure. The Mighty-Heart randomized clinical trial included Medicare- or Medicaid-enrolled adult (≥18 years) patients hospitalized with heart failure in 11 New York City (New York) hospitals between January 2021 and September 2024. Participants were randomized 1:1 to MIH or TOCC. TOCC provided a follow-up call by a nurse 48 to 72 hours after discharge. MIH included the same TOCC postdischarge call, and added ongoing nurse care coordination, community paramedic home visits, and facilitated synchronous telehealth with emergency medicine physicians. Data analysis occurred between September 2024 and June 2025. Receiving MIH plus TOCC or TOCC alone during the first 30 days after hospital discharge. Coprimary outcomes were health status at 30 days measured with the Kansas City Cardiomyopathy Questionnaire Overall Summary score, and 30-day all-cause hospital readmission, with heart failure-specific readmissions as a secondary outcome. Among 2003 participants (median IQR age, 67 58-78 years; 1040 female 52%), no adjusted differences were observed in the Kansas City Cardiomyopathy Questionnaire Overall Summary score at 30 days between MIH and TOCC groups (mean difference, 1.83; 95% CI, -0.75 to 4.40; P = .16). Exploratory analysis showed a significant age-by-treatment interaction effect, with younger participants who received MIH having larger improvement in health status (β: 4.40; 95% CI, 1.01 to 7.79). There were no significant differences in overall 30-day readmissions between study groups (20.3% vs 20.4%; odds ratio, 0.99; 95% CI, 0.83 to 1.19; P = .95). This randomized clinical trial found that MIH conferred no additional benefit on health status or 30-day readmissions for postacute patients with heart failure compared to TOCC alone. Preliminary subgroup analyses suggest potential variations in MIH effects by age and sex; therefore, further research is warranted. ClinicalTrials.gov Identifier: NCT04662541.
