Worsening of alcohol abuse disorder in a Spanish population during the first twelve months of the COVID-19 pandemic and associated factors: retrospective, ecological and community study.

PURPOSE

To analyse: (1) Changes in clinical parameters and in the use of social healthcare resources by patients with alcohol abuse disorder between the six months prior to the start of the pandemic and the first year of the pandemic. (2) The factors related to a worsening of clinical parameters among patients with alcohol abuse disorder.

METHODS

A retrospective and observational study of a population who have been diagnosed with alcohol abuse disorders according to their primary health care (PHC) electronic medical records was performed. The total sample was made up of 11,384 patients. The variables (sociodemographic variables, chronic comorbidities, analytical parameters related to alcohol abuse disorder, COVID-19 infection, and use of healthcare resources) were collected in three different time periods: (i) six months before the onset of the strict lockdown, (ii) six months following the end of lockdown and (iii) from six to twelve months after the end of lockdown. Paired Student's T-test and a multivariate logistic regression were performed.

RESULTS

Along the first year after the onset of the pandemic, between 44% and 54% of the patients suffered a decline in every clinical parameter. The number of PHC nursing, GP visits and social worker visits reduced significantly. As regards the associated factors related to deterioration of alcohol abuse disorder, being younger than 40 years old, having an income of over 18,000 euros/year and not having visited the social worker were associated with a worsening of the disorder.

CONCLUSIONS

These results suggest that the impact of COVID-19 on this group has been high, and the social care offered to these patients plays a significant role in minimising the repercussions of the pandemic.
