People with Substance or Alcohol Use Disorders (SUDs/AUDs) are likely to be more vulnerable to COVID-19 infection than the general population. We performed a cross-sectional study to compare the hospitalization rate (CHR) for COVID-19 in 2020 in patients diagnosed with SUDs or AUDs in the previous 10 years vs the population without these disorders (NAS). We included individuals who were resident in the Metropolitan Area of Bologna (Northern Italy). People with SUDs or AUDs have a greater probability of being hospitalized for COVID-19 infection compared to the general population NAS, suggesting that they suffer from worse physical symptoms/conditions than the general population. Furthermore, we found higher mortality rates during hospitalization for COVID-19 in patients with AUDs or SUDs than the general population NAS. These findings highlight the importance of a careful monitoring and early intervention measures in these patients.
