ControlHF's alert algorithm was built from prospective clinical data, validated in peer-reviewed trials, and refined through real-world deployment across 14 health systems. Every threshold has a reason. Every reason has a study.
Single-parameter alerts miss too many events and trigger too many false positives. ControlHF combines four physiologic and symptomatic signals into a continuously updated risk score — so alerts are meaningful, not noisy.
Each input is weighted by clinical urgency and trend velocity, not just instantaneous value. The composite score updates continuously and escalates through configurable thresholds tuned per patient.
ControlHF's algorithm and clinical workflows are grounded in a body of peer-reviewed evidence. The studies below directly inform alert thresholds, escalation pathways, and RPM protocol design.
A 14-center prospective cohort study (n=1,847) comparing ControlHF remote monitoring protocol against standard post-discharge care. Composite endpoint: HF readmission, ED visit, or death at 90 days. Adjusted hazard ratio 0.65 (95% CI 0.54–0.78, p<0.001).
Retrospective analysis of 623 decompensation events in 412 patients using ControlHF composite scoring versus single-parameter weight-gain alerts. Composite alert identified clinical deterioration a median 4.2 days before ED presentation (IQR 2.8–6.1 days) versus 1.1 days for single-parameter alerts.
Prospective blinded validation study (n=298) assessing ControlHF algorithm performance against clinical adjudication of decompensation events. Algorithm achieved 92% sensitivity and 87% specificity with positive predictive value of 0.81, outperforming all individual-parameter comparators tested.
ControlHF is designed around CMS RPM reimbursement pathways. For qualifying patients, the monthly RPM revenue from a single enrolled patient covers program costs and generates sustainable margin for your practice — with no capital expenditure required.
Reimbursement amounts reflect 2026 Medicare Physician Fee Schedule national non-facility rates. Commercial payer rates vary. ControlHF's billing support team assists with prior authorization, documentation requirements, and payer contracting. Consult your compliance team for program-specific guidance.
ControlHF is not a wellness app. It is a clinical-grade remote monitoring platform designed, tested, and operated under the regulatory and institutional frameworks that govern patient safety.
