Impact of remote biometric monitoring on cost and hospitalization outcomes in peritoneal dialysis.

INTRODUCTION: Peritoneal dialysis is a home-based therapy for individuals with end-stage renal disease. Telehealth, and in particular - remote monitoring, is making inroads in managing this cohort.

METHODS: We examined whether daily remote biometric monitoring (RBM) of blood pressure and weight among peritoneal dialysis patients was associated with changes in hospitalization rate and hospital length of stay, as well as outpatient, inpatient and overall cost of care.

RESULTS: Outpatient visit claim payment amounts (in US dollars derived from CMS data) decreased post-intervention relative to pre-intervention for those at age 18-54 years. For certain subgroups, non- or nearly-significant changes were found among female and Black participants. There was no change in inpatient costs post-intervention relative to pre-intervention for females and while the overall visit claim payment amounts increased in the outpatient setting slightly (US$511.41 (1990.30) vs . US$652.61 (2319.02), p  = 0.0783) and decreased in the inpatient setting (US$10,835.30 (6488.66) vs . US$10,678.88 (15,308.17), p  = 0.4588), these differences were not statistically significant. Overall cost was lower if RBM was used for assessment of blood pressure and/or weight (US$-734.51, p  < 0.05). Use of RBM collected weight was associated with fewer hospitalizations (adjusted odds ratio 0.54, 95% confidence interval 0.33-0.89) and fewer days hospitalized (adjusted odds ratio 0.46, 95% confidence interval 0.26-0.81). Use of RBM collected blood pressure was associated with increased days of hospitalization and increased odds of hospitalization.

CONCLUSIONS: RBM offers a powerful opportunity to provide care to those receiving home therapies such as peritoneal dialysis. RBM may be associated with reduction in both inpatient and outpatient costs for specific sub-groups receiving peritoneal dialysis.
