Abstract

BACKGROUND: Penicillin skin testing (PST) is increasingly used as a tool to evaluate penicillin allergy in patients with a reported history. The limited availability of allergists, however, may be an impeding factor. OBJECTIVE: We sought to assess the clinical utility of telemedicine to facilitate PST. METHODS: Penicillin-allergic inpatients receiving systemic antibiotics were prospectively identified between April and August 2017. Qualifying patients underwent PST performed by a trained allergy/immunology physician assistant (PA). On completion of PST, a telemedicine consultation, through the use of real-time interactive video conferencing (Microsoft Lync 2013, Redmond, Wash), was performed remotely by an allergist. Patients were surveyed regarding their satisfaction with the telemedicine experience. RESULTS: Fifty patients consented to PST through a telemedicine consultation. The average total time to complete a consultation was 128 minutes (standard deviation [SD] ± 33). Of this, the average PA travel time was 46 minutes (36%) with the remaining time spent on clinical services (82 minutes, 64%). The average physician telemedicine time per patient was 5 minutes (SD ± 2). Patients rated their experience as an average of 4.5 on a scale of 1 (highly unsatisfied) to 5 (highly satisfied). Of the 46 PST-negative patients, 33 were transitioned to a β-lactam antibiotic that reduced the use of vancomycin, metronidazole, aztreonam, aminoglycosides, and clindamycin (P < .05). More than $30,000 was saved throughout the study period. CONCLUSIONS: Telemedicine is an effective and novel approach to facilitate PST in the inpatient setting and carries a high degree of patient satisfaction. This method has the potential to optimize and improve access to allergy/immunology resources.
