ABSTRACT
OBJECTIVE:
We describe the construction of a hearing aid long-term use persistence measure based on battery reorder data. The measure is derived from the notion that hearing aid users keep using their devices for some time after placing a battery order.DESIGN:
A hearing aid user is defined as persistent at time T if they placed a battery order within a time span W preceding T. We characterize and validate this measure using electronic health records from a large sample of US Veterans.RESULTS:
We describe how to choose parameters T and W for calculating persistence rates in the patient sample. For validation, the associations of persistence with (1) the duration over which users received outpatient hearing aid care; (2) self-reported hearing aid use shortly after fitting; and (3) patient age and hearing loss are investigated. In all cases, plausible dependencies are observed.CONCLUSIONS:
We conclude that our persistence measure is viable and hope this will motivate its use in similar studies.
