Study objective: Remote monitoring (RM) can help patients with heart failure (HF) remain free of hospitalization. Our objective was to implement a patient-centered RM program that ensured timely clinical response, which would be associated with reduced mortality.
Design: This was a retrospective, observational, propensity-matched study.
Setting: A large regional health system between 9/1/2016-1/31/2018.
Participants: Patients admitted with acute HF exacerbation were matched on key variables. Up to two comparison patients were selected for each RM user.
Interventions: We used an algorithmic approach to assess daily physiologic data, assess symptoms, provide patient education, encourage patient self-management, and triage medical problems.
Main outcome measures: We assessed all-cause mortality using Kaplan-Meier and log rank analysis. We used Cox proportional hazards to compare risk of death.
Results: Our cohort of 680 RM users and 1198 comparisons were similar across baseline characteristics except age (74.7 years versus 76.6 years, p < 0.001, respectively). Having one or more admissions in the preceding 120 days was more prevalent in the RM group (35.9% versus 29.8%, p = 0.013). The 30- and 90-day all-cause readmission rates were each higher among the RM users compared with the comparison patients (p = 0.013 and p < 0.001 for 30 and 90 days, respectively). Mortality was lower in the RM group at 30 and 90 days post-discharge (p < 0.001).
Conclusions: RM that responds to biometric data and encourages patient self-management can be used in a large hospital system and is associated with decreased all-cause mortality. Our findings underscore RM technology as a method to improve HF care.
