Objectives: Inappropriate use of telemetry monitoring is associated with alarm fatigue, an increase in health care expenditures, and the potential for patient harm from interventions in clinically inconsequential arrhythmias. We explored adherence to current guidelines for appropriateness of (1) initial telemetry assignment and (2) duration of the assignment.
Study design: Retrospective study.
Methods: After institutional review board approval, 695 consecutive adult patients (≥ 18 years) who were admitted with any diagnosis to general medical floors and assigned telemetry at the time of admission over 3 months were enrolled. Patients on surgical service and transferred from critical care were excluded. Data were collected from electronic health records (EHRs).
Results: We observed that 155 of 695 (22.3%) patients had been inappropriately assigned telemetry at the time of initial assignment. Of the 540 patients appropriately assigned telemetry, 56.3% of patients had longer than the recommended duration of telemetry monitoring with a median (interquartile range) of 3 (2-4) nonindicated days per patient. The annualized additional cost of telemetry monitoring due to the inefficient utilization was found to be more than $500,000 per year.
Conclusions: Our data further support the need for frequent reassessment of telemetry indication, which can be facilitated by the utilization of EHR-based automated monitoring.
