Uchida T, Hirano J, Sakurai H, et al. - Researchers investigated the prevalence of concomitant use of benzodiazepine hypnotics and alcohol in psychiatric outpatients and sought for the clinical characteristics and factors that are linked with the concomitant use. In addition, they examined whether the psychiatrists-in-charge is aware of the concomitant use. For 7 consecutive days, outpatients with schizophrenia, depression, and insomnia who were receiving benzodiazepine hypnotics were asked to fill in a sleeping diary; in the diary, they also recorded the use of hypnotics and alcohol. The concomitant use was reported in 39.8% (37/93). They observed a significant positive association between the CAGE score and the concomitant use (odds ratio = 2.40) indicating the utility of the CAGE questionnaire to screen such potentially hazardous users. The psychiatrists suspected concomitant use in only 32.4% of the concomitant users. This suggests that treating psychiatrists frequently overlook concomitantly used benzodiazepine hypnotics and alcohol.
