However, the current study is the first to examine store-and-forward technology for psychiatry, said Peter Yellowlees, professor of psychiatry and behavioural sciences and the study's lead author. "A Feasibility Study of the Use of Asynchronous Telepsychiatry for Psychiatric Consultations" is published in the August issue of the journal Psychiatric Services.
"We've demonstrated that this approach is feasible and very efficient", stated Peter Yellowlees, who is an internationally recognized expert in telepsychiatry. "Using store-and-forward technology allows us to provide opinions to primary-care doctors much more quickly than would usually be the case."
The researchers conducted the study to determine the effectiveness of asynchronous telepsychiatry for patients in Tulare County, a rural county in California's San Joaquin Valley. Sixty male and female patients between the ages of 27 and 64 who had mostly mild-to-moderate mental-health disorders were included in the study.
Researcher Alberto Odor, associate adjunct professor of anaesthesiology and pain medicine, conducted 20- to 30-minute structured videotaped interviews at a community-based primary-care clinic. The videos were then uploaded to UC Davis' specially designed Web-based telepsychiatry consultation record. Peter Yellowlees and Donald Hilty, professor of psychiatry and behavioural sciences, reviewed the videotapes and provided psychiatric evaluations to the patients' community-based primary-care physicians.
Fifty-one percent of patients received diagnoses of mood disorders, 19 percent received diagnoses of substance use disorders, 32 percent received diagnoses of anxiety disorders and 5 percent received other diagnoses - including kleptomania, schizophrenia and parasomnia. Five patients also were diagnosed with disorders such as borderline personality disorder, obsessive-compulsive disorder or personality disorder. Some of the individuals had multiple diagnoses.
One patient was referred for a face-to-face consultation with a psychiatrist because of the possibility of a diagnosis of early psychosis. The psychiatrists recommended additional laboratory evaluations for more than 80 percent of patients and made recommendations for medication changes in 95 percent of patients. In instances where medication changes were recommended, physicians also received long-term treatment plans. A variety of psychotherapies, such as individual and cognitive-behavioural therapy, were recommended for many of the patients. Community-based primary-care physicians said they found the practice worked well, according to the study.
The consulting psychiatrists provided feedback to referring physicians within two weeks, but asynchronous telepsychiatry could occur within 24 hours if it were to become a regular service, Peter Yellowlees said.
Asynchronous telepsychiatry should not take the place of face-to-face psychiatric evaluations and is not suitable for patients with urgent psychiatric conditions, he said. But there are a number of circumstances in which it would be helpful in providing more primary-care physicians greater access to psychiatric consultations.
"There is a substantial shortage of psychiatrists", Peter Yellowlees stated. "Asynchronous telepsychiatry would allow us to have better access to information about patients being referred by primary providers and to provide more comprehensive opinions. This approach could be used by the military and in many different rural and metropolitan settings. It signals the beginning of the true multimedia electronic medical record with clinical video recordings becoming part of the data set."
In addition to Peter Yellowlees, Donald Hilty and Alberto Odor, other study authors include Ana-Maria Iosif and Michelle Burke Parish, both of UC Davis, and Karen Haught of the Tulare County Department of Public Health. The study was funded by the Blue Shield of California Foundation.
The UC Davis School of Medicine is among the United States' leading medical schools, recognized for its research and primary-care programmes. The school offers fully accredited master's degree programmes in public health and in informatics, and its combined M.D.-Ph.D. programme is training the next generation of physician-scientists to conduct high-impact research and translate discoveries into better clinical care. Along with being a recognized expert in medical research, the school is committed to serving underserved communities and advancing rural health.
