Short-Term Impact of Remote Patient Monitoring on Total Cost of Care Among High-Acuity Medicare Beneficiaries: A Retrospective Pre–Post Cohort Analysis
Wesley Smith, Angela Orsky, Joseph A. Ewing, Craig FlanaganBackground:
High-acuity Medicare beneficiaries with annual expenditures exceeding $12,000 disproportionately drive the total cost of care (TCOC) through preventable acute utilization and are natural candidates for value-based and shared savings arrangements. Whether remote patient monitoring (RPM) produces near-term TCOC reductions in this cost-stratified population has been insufficiently evaluated in real-world practice.
Methods:
A retrospective pre–post cohort analysis was conducted among 597 Medicare beneficiaries enrolled for at least 5 months in a technology-enabled RPM program, each with annualized preenrollment TCOC ≥$12,000. Patients received a cellular-enabled blood pressure monitor linked to a HIPAA-compliant platform staffed by licensed care navigators. The primary outcome was change in annualized TCOC over the 12 months before and after program initiation. Given right-skewed cost distribution (skewness = 4.47), the Wilcoxon signed-rank test was the primary inferential procedure. Secondary outcomes included per-1,000-patient rates of emergency department (ED) visits, inpatient hospitalizations, and 30-day readmissions.
Results:
The mean age was 76.6 ± 8.2 years; 55.6% were female. The median annualized TCOC declined from $25,956 to $11,792, a reduction of $10,932 per patient (Wilcoxon
Conclusion:
Short-term RPM participation was associated with substantial reductions in TCOC and acute utilization among high-acuity Medicare beneficiaries, supporting RPM as a viable intervention to advance this population toward value-based care models. Prospective controlled evaluation is warranted to establish causal attribution.
