Evaluación de las alteraciones del sueño en pacientes drogodependientes hospitalizados

Abstract

Background and objectiveWe aimed to study the relationship between sleep disorders and the type of substance use and the number of previous hospitalizations in patients admitted in a detoxification unit. Patients and methodsWe evaluated 150 drug-dependent inpatients with SCID-I. Patients were asked to complete an 11-item questionnaire measure (Likert scales from 1-minimum to 7-maximum) designed to assess the relationship between sleep disorders and drug use. Results75.3% were men. 39% were alcoholic, 34,67% cocaine-users, 30% poly-drug users, 22.6% opioid, 18% benzodiazepine and 14% cannabis-dependent patients. 68.1% reported experiencing sleep problems. 80.1% related sleep disorders to drug consumption. Worry about sleep problems was found in all patients with previous hospitalizations (47.3%). This group experienced more insomnia than those who had never been hospitalized (43.7 vs 22.8%, P<.05). Poly-drug users perceived more sleep disorders (57.8 vs 24.3%, P<.05). Insomnia was referred by 61% of alcoholic patients. 86% of the sample used benzodiazepines, 75.4% used them without prescription. ConclusionsThe perception of suffering from disordered sleep is frequent in drug addicts. Patients with poly-drug use and previous hospitalizations were the most affected.
