Abstract

Introduction People addicted to illegal drugs were discussed as a risk group for SARS-CoV-2 infections, with increased susceptibility and a severe course of infection.

Methods In this study, the frequency of SARS-CoV-2 infections of drug-dependent persons admitted to inpatient detoxification treatment in five psychiatric hospitals was determined by implementing routine polymerase chain reaction (PCR)-testing at admission (9/2020) up to one year. Main substance-related diagnosis, comorbid respiratory disease, housing situation, and current opioid maintenance treatment (OMT) were documented. An age-matched control group of psychiatric inpatients without dependence from illegal drugs was established.

Results Data from 1675 patients (male 79.5%; mean age 39.5 years; opioid dependence 81.5% homelessness; 2.4%; chronic respiratory disease 6.3%) were included. Out of 1365 patients dependent on opioids, 50.2% were currently in OMT. Six (3 female; mean age 40.3 years) patients tested positive for SARS-CoV-2 by PCR (0.36%), and none showed symptoms of COVID-19. All six were opioid dependent, 5 currently not in OMT. In the control group, 11 out of 1811 inpatients tested positive (0.61%).

Discussion The rate of SARS-CoV-2-infections in persons with dependence on illegal drugs was not increased compared to a control group of psychiatric patients. OMT is presumably a protective factor, e. g. in the participating cities, OMT facilities offered an easy access to vaccination programs. In contrast, drug addicts in the USA were severely affected by the pandemic. Differences between countries might partially be explained by social factors such as the higher availability of OMT in Germany and a much lower frequency of homelessness.
