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 í µí± if they placed a battery order within a timespan í µí± preceding í µí±. We characterize and validate this measure using electronic health records from a large sample of US Veterans. Results: We describe how to choose parameters í µí± and í µí± for calculating persistence rates in the patient sample. For validation, the associations of persistence with (a) the duration over which users received outpatient hearing-aid care, (b) self-reported hearing-aid use shortly after fitting, (c) 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.
