A Telemonitoring Intervention for Cirrhotic Ascites Management Is Cost-Saving.

Abstract

BackgroundPatients with cirrhosis and ascites experience frequent hospital admissions, leading to poor quality of life and high healthcare costs. Monitoring weight is a component of ascites care and telemonitoring may improve outcomes and costs.GoalsWe aimed to evaluate the cost and outcomes of current care compared to a telemonitoring system for ascites.StudyWe developed a decision-analytic model that examined 100 simulated patients over a 6-month horizon. We compared usual care to a new telemonitoring program, which we estimate costs $50,000/6 months.ResultsThe cost of standard of care for 100 patients with cirrhotic ascites over a 6-month period is $167,500 more expensive than telemonitoring. By varying parameter probabilities by ± 10% and outcome costs by ± 20%, we found that standard of care remains more expensive than care with a telemonitoring intervention by $9400 to $340,200 per 6-month period. Standard of care leads to 9 more admissions (range 4 to 12) than a telemonitoring intervention, while telemonitoring leads to 9 more outpatient visits (range 6 to 9) and 28 additional outpatient large volume paracenteses (LVPs) (range 17 to 28). With more and less expensive telemonitoring interventions, standard of care remained more expensive. With 50% adherence to the intervention, standard of care was $89,848 more expensive.ConclusionsIn almost all probability and cost scenarios, a telemonitoring intervention is cost-saving for the management of cirrhotic ascites. Using hospital admissions as a surrogate for quality of care, patient outcomes are improved primarily though more proactive medical intervention and more LVPs.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10620-021-07013-2.
