ABSTRACT
Previous reports of telemedicine consultations have demonstrated that the technology is effective but inefficient. Little attention has been directed to the use of telemedicine in a primary care practice, especially the use of the medical peripheral devices. We used a functioning primary care practice as a telemedicine test bed, providing unselected patients in the study group. The goal was to study the performance of a new generation of a compact set of medical peripheral devices specifically designed for telemedicine examinations. In a 3-week field trial, 2 second-generation camera systems were used by physician faculty and residents in family practice to examine the skin, ears, and pharynx of 34 patients, ranging in age from 10 months to 78 years. Evaluations by the clinicians and patients were obtained. The average duration of an examination using these systems was 2 minutes. Patients' response was uniformly positive. A "pistol grip" video otoscope obtained an acceptable image, unless canal debris obscured the view. The system that provided pneumatic otoscopy was preferred, with some modifications necessary to obtain an airtight seal. The preferred skin camera was one that provided an image of a size that clinicians were most accustomed to viewing, although stability of this handheld camera was a problem. This camera also worked well to visualize the pharynx, especially in children with symptoms of pharyngitis. Color was deemed important in all 3 anatomical areas, and using auto-white balance and excluding fluorescent lights were preferred. Thus, the second-generation telemedicine peripheral devices were effective for use in a group of unselected primary care patients. These camera systems can be used by nursing personnel and require a minimum of time per examination.
