The Veterans Administration system supports telemedicine (TM) to provide medical consultations between patients and physicians via videoconference. At present, little is known about the impact of such TM consultations on patient-physician communication and related health outcomes. Analyses of in-person (IP) medical encounters have shown that effective patient-physician communication is associated with improved health outcomes.
To determine whether the physical separation between patient and physician required during TM has an affect on patient-physician communication and related outcomes, including patient and physician satisfaction, patient compliance, and patient understanding of medical care.
In this clinical trial, 238 patients were randomized to receive either consultative care at the remote site via TM with a consultant physician located the Milwaukee VA (intervention) OR by an IP consultation with a consultant physician at the Milwaukee VA (control). The same group of consultant physicians provided both IP and TM consultations.
Patients in both study arms had their medical encounter video recorded. We compared patterns and quality of patient-physician communication for the TM and IP encounters, using the Roter Interaction Analysis System. Data on patient and physician satisfaction with the encounter and patients' understanding of their medical problems were collected at the end of each medical encounter. Patient compliance (medication refill behavior) was assessed at 90 days post visit. The frequency of communication behaviors during the TM and IP encounters was compared using the analysis of a Linear Mixed Model. Comparison of patient satisfaction, physician satisfaction, patient compliance, and patient knowledge measures between TM and IP groups were conducted with similar Linear Mixed Models.
