The implementation of teletherapy with patients with Severe Mental Illness during the COVID-19 first wave and its longitudinal association with hospitalisations: A retrospective multicenter study from Spain

Introduction The COVID-19 related restrictions such as social distancing forced the search for feasible alternatives to the provision of care for patients with severe mental illness (SMI), with services opting for teletherapy as an substitute of face-to-face treatment. Objectives To examine the implementation of teletherapy (telephone, videoconference) with patients with SMI during the COVID-19 first wave, and explore its associations with reduced hospitalisations after the first wave was over. Methods We performed a retrospective assessment of 270 records of patients visiting fifteen outpatient mental health services across Spain during 2020. We retrieved sociodemographic and clinical data, including modality of received therapy (in-person, telephone, videoconference) in three time points (before, during and after the first COVID-19 wave) and hospitalisation rates two, four and six months later. Results During the first wave, services implemented teletherapy (telephone and videoconference) extensively, whilst they reduced face-to-face therapy, though this returned to previous levels after the first wave. Hospitalisations two months later did not differ between patients who received teletherapy, and those who did not (p=.068). However, hospitalisations were lower for the first group of patients four (p =.004) and six months later (p
