Modeling the Therapeutic Process of Patients with Cocaine Use Disorders: The Texas Christian University Process Model as a Guidance to Predict Readmission

BackgroundPatients readmitted for Cocaine Use Disorders are, along with Opiates Use Disorder, one of the group of patients with highest demand of treatment in specialized centers of addiction and with greater therapeutic failure. ObjectiveOur aim is to apply the Texas Christian University Process Model to modeling the relationships between patients attributes at intake of treatment, treatment progress indicators and outcomes, including treatment success and readmissions. MethodA retrospective observational design was used with 10,298 Cocaine Use Disorder patients. Electronic health records were used for statistical analysis of the data. Randomized subsample 1 (n= 5,150) was used for exploratory analysis and subsample 2 (n = 5,148) to modeling variables relations. ResultsPatients attributes at intake have limited relevance in explaining the treatment progress indicators and outcomes. Time on treatment and patients adherence are relevant to explain treatment success. Readmissions are mainly explained by time in treatment and therapeutic success. Been referred to addiction centers by health of services also appear to be relevant. Discussion and conclusionOur study reflects that the therapeutic process is important in order to have and adequate therapeutic adherence and to stay longer in treatment. Patients with a successful treatment and longer stay in treatment are less likely to have future readmissions. Through this study we highlight, therefore, the value of an adequate therapeutic adherence to obtain successful short- and medium-term results. This would make the treatment of these patients more efficient, and alleviate suffering for the patients and their families.
