Study contributions Main results A sharp decrease in hospitalization rates due to mental and behavioral disorders was seen in Brazil after the onset of the COVID-19 pandemic, this being evidence that the pandemic affected the mental health care network. Implications for services There is evidence that there is a delay between the appearance of the first symptoms of mental disorders and seeking specialized care, which means that the consequences of the pandemic for psychosocial care will probably be seen in the years to come. Perspectives The change in the National Mental Health Policy, in the period analyzed, may lead to a misinterpretation of the change in the pattern of hospitalizations due to the pandemic, requiring future studies in order to gain a better understanding of the phenomenon.
