Abstract
Background and Objectives
Cocaine is a highly addictive substance, and with no approved medication for cocaine use disorder (CUD), leading to a heavy burden. Despite validated psychosocial treatments, relapse rates after detoxification are very high in CUD. Few consistent factors can predict abstinence after detoxification. Our study, therefore, aimed at identifying factors predicting abstinence among CUD patients after inpatient detoxification.
Methods
Eighty-one CUD inpatients were included during detoxification and characterized for clinical and sociodemographic data at baseline and at a follow-up of 3 months after discharge, including a standard measure of their abstinence duration from cocaine. We performed Cox univariate analyzes to determine the factors associated with abstinence maintenance, followed by a multivariate Cox regression to identify independent predictors.
Results
Abstinence maintenance was shorter in patients injecting cocaine (hazard ratio [HR] = 5.16, 95% confidence interval [CI]: 2.01–13.27, p < .001) and using cocaine heavily in the month before inclusion (HR = 1.03, 95% CI: 1.00–1.06, p = .046). Conversely, abstinence maintenance was longer in patients with longer inpatient detoxification stays (HR = 0.96, 95% CI: 0.94–0.99, p = .015) and prescribed with selective serotonin reuptake inhibitors (SSRIs) (HR = 0.30, 95% CI: 0.16–0.56, p < .001).
Discussion and Conclusions
Patients with severe CUD may require longer inpatient stays to achieve abstinence. Regarding SSRI prescription, more specific studies are needed to provide stronger recommendations about their use in clinical practice.
Scientific Significance
Our findings suggest several modifiable factors to improve inpatient treatment response in CUD. As there are no specific recommendations about the optimal duration of inpatient stay, our results could pave the way for evidence-based guidelines.
期刊介绍:
The American Journal on Addictions is the official journal of the American Academy of Addiction Psychiatry. The Academy encourages research on the etiology, prevention, identification, and treatment of substance abuse; thus, the journal provides a forum for the dissemination of information in the extensive field of addiction. Each issue of this publication covers a wide variety of topics ranging from codependence to genetics, epidemiology to dual diagnostics, etiology to neuroscience, and much more. Features of the journal, all written by experts in the field, include special overview articles, clinical or basic research papers, clinical updates, and book reviews within the area of addictions.
