The Efficacy of Telepsychiatry in Addiction Patients: A Systematic ReviewSubstance abuse treatment via telepsychiatry expeditiously increased with the start of the pandemic and has brought changes to its rules and regulations. In this study, we focused on the prognosis of substance abuse patients treated with telepsychiatry, the various changes that occurred during the pandemic, and the difficulties faced by clinicians using telepsychiatry. We concluded that telepsychiatry use for substance abuse patients increased during the pandemic, and the prognosis of these patients treated with telepsychiatry was similar to that of in-person treatment. However, a combination of telepsychiatry with in-person sessions showed much better results.
