Recognizing the importance of close follow-up after hypertensive disorders of pregnancy (HDP), many centers have initiated programs to support postpartum remote blood pressure management (RBPM). We aim to evaluate the cost-effectiveness of RBPM to inform scalability of these programmatic interventions. We conducted a cost-effectiveness analysis of utilizing RBPM to manage postpartum hypertension versus usual care. The modeled RBPM included provision of a home blood pressure (BP) monitor, guidance on warning symptoms, instructions on BP self-monitoring twice daily, and clinical staff to manage population-level BPs as appropriate. Usual care was defined as guidance on warning symptoms and recommendation for one outpatient visit for BP monitoring within a week of discharge. We designed a Markov model that ran over 14 one-day cycles to reflect the initial two weeks after delivery when most ED visits and readmissions occur and RBPM is clinically anticipated to be most impactful. Parameter values for base case scenario were derived from both internal data and literature review. QALYs were calculated over the first year postpartum and reflected the short-term morbidities associated with HDP that, for most birthing people, resolve by two weeks postpartum. Sensitivity analyses were performed to assess strength and validity of the model. Primary outcome was incremental cost effectiveness ratio (ICER) defined as cost needed to gain one quality adjusted life year (QALY). Secondary outcome was incremental cost per readmission averted. Analyses were performed from a societal perspective. In the base case scenario, utilizing RBPM was the dominant strategy (i.e., cost less, higher QALYs). In univariate sensitivity analyses, the most cost-effective strategy shifted to usual care when cost of readmission fell below $2,987.92 and rate of reported severe range BP with a response in RBPM was less than 1%. Assuming a willingness-to-pay of $100,000 per QALY, utilizing RBPM was cost-effective in 99.28% of simulations in a Monte Carlo analysis. Using readmissions averted as a secondary effectiveness outcome, the incremental cost per readmission averted was $145.00. Remote blood pressure management of postpartum hypertension is cost saving with better outcomes compared to usual care. These data can be used to inform future dissemination of and support funding for RBPM programs.
