Is telepsychiatry equivalent to face-to-face psychiatry? Results from a randomized controlled equivalence trial.

OBJECTIVE: The use of interactive videoconferencing to provide psychiatric services to geographically remote regions, often referred to as telepsychiatry, has gained wide acceptance. However, it is not known whether clinical outcomes of telepsychiatry are as good as those achieved through face-to-face contact. This study compared a variety of clinical outcomes after psychiatric consultation and, where needed, brief follow-up for outpatients referred to a psychiatric clinic in Canada who were randomly assigned to be examined face to face or by telepsychiatry. METHODS: A total of 495 patients in Ontario, Canada, referred by their family physician for psychiatric consultation were randomly assigned to be examined face to face (N=254) or by telepsychiatry (N=241). The treating psychiatrists had the option of providing monthly follow-up appointments for up to four months. The study tested the equivalence of the two forms of service delivery on a variety of outcome measures. RESULTS: Psychiatric consultation and follow-up delivered by telepsychiatry produced clinical outcomes that were equivalent to those achieved when the service was provided face to face. Patients in the two groups expressed similar levels of satisfaction with service. An analysis limited to the cost of providing the clinical service indicated that telepsychiatry was at least 10% less expensive per patient than service provided face to face. CONCLUSIONS: Psychiatric consultation and short-term follow-up can be as effective when delivered by telepsychiatry as when provided face to face. These findings do not necessarily mean that other types of mental health services, for example, various types of psychotherapy, are as effective when provided by telepsychiatry.

Renal impairment and medication use among psychogeriatric inpatients.

OBJECTIVES: To determine the prevalence of renal impairment and the dosage appropriateness of several medications for which dosing guidelines in the advent of renal impairment are available. METHOD: The authors assessed the renal function and medication use of 37 psychogeriatric patients (mean age of 75 years) living in a psychiatric hospital. Renal function was determined by serum creatinine (SCr) levels and creatinine clearance (CCr) data using the Cockcroft and Gault equation. RESULTS: Thirteen of 37 patients (35%) were found to have renal impairment according to CCr data but only two patients (6%) were considered impaired according to SCr levels (k=0.19). Of 44 medications for which dosing guidelines were available, only two (5%) were prescribed inappropriately. CONCLUSION: These data suggest that CCr data should be used over SCr levels to determine renal impairment and to support the monitoring of psychogeriatric patients for declines in renal function and required medication adjustments.
