Introduction:
The use of psychoactive substances in patients diagnosed with mental illness is an increasing public health problem; the purpose of this work was to carry out a study to identify the most prevalent psychoactive drug abuse patterns in hospitalized patients in a psychiatric hospital, to estimate the severity of substance abuse, as well as to determine the factors associated with drug consumption using multivariate statistical modeling.
Methods
An analytical, retrospective study was carried out through the review of patient records discharged during 2018. Sociodemographic data, diagnoses, clinical follow-up information, clinimetric score of the alcohol consumption, Tobacco and Substances Detection Test (ASSIST 2.0) were obtained as well as the toxicological profile results.
Results
A representative sample of 268 participants was obtained, 61.6% men and 38.4% women, 86.6% unemployed, 67.9% single, with an average age of 36 years and 8 years of schooling. The most frequent diagnoses were Schizophrenia (42%), Substance-Induced Psychotic Disorder (22%), and Bipolar Disorder (17.9%). The most frequent substances detected in urine toxicology test were: Cannabis 21.8% (n = 45) and methamphetamines 10.7% (n = 22). The substances with the most frequent consumption in the last 3 months were tobacco, ethanol, cannabis, and methamphetamines. The highest score in the severity of consumption were methamphetamines and cannabis. The most important predictors for ethanol consumption were tobacco and cannabis abuse, for cannabis abuse were schooling years and ethanol consumption, and for methamphetamine consumption, the most important predictors were cocaine and cannabis abuse.
Conclusions
Young, male, unemployed subjects, with lower educational level, a psychiatric condition, and psychoactive consumption represent an identifiable "sociodemographic phenotype" that has an increased risk of requiring hospital services on a more recurrent basis and that could represent a burden to the health system. Methamphetamines abuse continues to increase and is becoming a significant mental health and public health issue. Cannabis and methamphetamine use are more severe and have more serious repercussions in terms of psychiatric morbidity. Correct public policies must be designed to intervene in this population.
