Objectives:
We sought to characterize the correlation between diagnoses made during telerheumatology and face-to-face visits and to document patients' satisfaction with telerheumatology visits.
Methods:
This quality assurance study of the use of telerheumatology evaluated new patients referred to a Veterans Affairs rheumatology clinic. Patients were seen at a community clinic by a nurse practitioner with a rheumatologist participating in the encounter via telelink. All of the patients had a second face-to-face visit with the same rheumatologist. Diagnoses made during telerheumatology and face-to-face visits were compared. Patients' satisfaction with telerheumatology was ascertained.
Results:
Thirty-eight patients were included in the study. Initially, 23 were diagnosed as having an inflammatory or rheumatic condition; 15 were subsequently confirmed at the face-to-face visits. All of the patients with inflammatory, rheumatic conditions were identified at the telerheumatology visits. The overall correlation was 79% between the telerheumatology and face-to-face visits. Among patients with inflammatory, rheumatic conditions, 66% preferred a face-to-face visit compared with 41% among those without such conditions (not significant). Immediately after the telerheumatology visit, all of the patients gave a 10 out of 10 rating for satisfaction. During the subsequent telephone survey, 30 remained highly satisfied with the telemedicine encounter (10 out of 10 rating).
Conclusions:
Telerheumatology at the Palo Alto Veterans Affairs was well received by patients; provided an accurate diagnosis of noninflammatory, nonrheumatic conditions; and may be appropriate for screening and prioritizing patients for in-person rheumatology clinics.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
