Abstract
BACKGROUND: Some studies have demonstrated poor patient compliance with carrying and administering self-injectable epinephrine (SIE). No study has attempted to define the number or characteristics of patients who are prescribed SIE and subsequently do not retrieve the prescription. OBJECTIVES: To determine fill rates of SIE prescriptions and to provide a descriptive report of patients who do not fill those prescriptions. METHODS: This was a retrospective review of electronic medical records of patients prescribed SIE at a large military medical center in a 1-year period. Rates of prescription retrieval were determined, and patient demographic information was collected. Additional information recorded included the number of devices prescribed per prescription, the International Classification of Diseases, Ninth Revision, code associated with each prescription, and the ambulatory care setting associated with the patient encounter resulting in the prescription. Statistical analysis was performed using the chi2 test. RESULTS: There were 881 SIE prescriptions entered for 769 patients, and 630 patients (82%) filled at least 1 prescription. Individuals older than 55 years filled their SIE prescriptions more often than those 55 years and younger (P < .009), and prescriptions were filled more often from outpatient clinics compared with the emergency department (P < .01). There were no statistically significant differences in fill rates based on sex, active-duty military status, or diagnosis. CONCLUSIONS: Elderly patients and those receiving care in clinic settings are more likely to fill an SIE prescription. Determining why patients do not fill an SIE prescription may help focus patient education efforts.
