mental health specialist video consultations for primary care patients

Conditions: Depression; Anxiety Disorder

Summary: even in western health care systems, most people with mental disorders, including those with severe and chronic disorders, are treated solely by their general practitioner (gp). notably, the accessibility of mental health specialist care is mainly complicated by (a) long waiting times for specialists, (b) long travel distances to specialists, particularly in rural and remote areas, (c) patients' reservations about mental health specialist care (including fear of being stigmatised by seeking such care). to mitigate those barriers, technology-based integrated care models have been proposed. the purpose of this study is to measure the effectiveness of a mental health specialist video consultations model versus treatment as usual in patients with depression or anxiety disorders in primary care. in an individually randomized, prospective, two-arm superiority study with parallel group design, n = 320 patients with anxiety and/or depressive disorder will be recruited in gp practices.

the purpose of this study is to measure the effectiveness of a mental health specialist video consultations model versus treatment as usual in patients with depression or anxiety disorders in primary care. in total, the investigators plan to enrol 320 patients who will be randomly allocated to the experimental condition (mental health specialist video consultations) or the control condition (treatment as usual from their gp) in a 1:1 ratio. general practitioners will recruit patients during their regular clinic hours. if the patient is interested in participation, the patient will receive the informed consent form and the baseline questionnaire from the gp. the practice team will send the patient's contact details to the study team who will screen the patient with respect to the eligibility criteria. patients will be randomly allocated to one of the two study conditions (video consultation model vs. treatment-as-usual, tau) in a 1:1 ratio by central randomisation. the evaluation of the primary outcome will be performed according to the intention-to-treat principle. the health economic evaluation will be carried out from the perspective of society. a cost-effectiveness and a cost-utility analysis will be carried out.
