Abstract Outpatient ambulatory electrocardiographic monitoring (AEM) is often used by practitioners to diagnose an arrhythmia. AEM devices can be mailed to the patient’s home or applied in the office setting. A common barrier that decreases the diagnostic utility is failure to successfully complete the monitoring. Objective: The purpose of this study is to compare the AEM completion rates between patients who self-apply the monitor at home and those who have the monitor applied in the office by clinical staff. Methods: A cross-sectional retrospective chart review was used. The electronic health records were reviewed for billable codes before and after April 2018 when a new office policy of mailing monitors to patients was implemented. A random sample of 50 patients was obtained from each timeframe. Results: The sample included the electronic medical records of adult patients (n=100) seen in the Cardiology clinic. Over half 63 (63%) were female, and the majority 88 (88%) were Caucasian, with 10 (10%) Black or African American, and 1 (1%) reporting Asian race. The average age was 59 (range 20-100). Most patients 98 (98%) had health insurance. The office application group had a significantly higher rate of successful completion 62 (62%) compared to the mail group 38 (38%). The average number of days that the AEM was worn was 18 days (range 7-30 days). Conclusion: The results of this study indicate that professional support and application of AEM in the clinic setting may lead to an increase in completion rates.
