Mental health outcomes of adults hospitalized for COVID-19: A systematic review

•The best available evidence suggests many patients may experience mental health symptoms during and 3 months after hospitalization for COVID-19.•However, patients infrequently receive a new mental health disorder diagnosis 6 months after hospitalization.•Some patients – including women and those with more severe COVID-19 – may be at higher risk of poor mental health outcomes.•More research is needed on patients’ mental health care utilization and resource needs after hospitalization for COVID-19, as the current evidence is limited.
