Reduced Healthcare Use and Apparent Savings with Passive Home Monitoring Technology: A Pilot Study.

OBJECTIVES

To conduct a cost analysis of ambient assisted living technology, which is promising for improving the ability of individuals and care providers to monitor daily activities and gain better awareness through proactive management of health and safety.

DESIGN

Three-arm cohort study.

SETTING

Homes of enrollees of a state-based healthcare plan for older adults.

PARTICIPANTS

Enrollees dually eligible for Medicare and Medicaid (N = 268).

INTERVENTION

Health and safety passive remote patient monitoring (PRPM) systems were installed in enrollees' homes (the intervention group) with monitoring and proactive intervention of a case manager when deviation from baseline subject behavior was detected.

MEASUREMENTS

Claims data were collected over 12 months to assess healthcare use and costs in the intervention group and to compare use and costs with those of two control groups: a concurrent group of enrollees who declined the technology and a historical cohort matched on age to the participation group.

RESULTS

Although the small sample size precluded cost differences that were statistically significant, the participant group used substantially less custodial care, emergency department (ED) services, inpatient stays, and ED costs than the two control groups.

CONCLUSION

In this pilot study, the PRPM system was associated with apparent healthcare cost savings. Although more cost analyses are warranted, ambient assisted living technologies are a potentially valuable investment for older adult care.
