- Résumé :
- Purpose Addictive behaviours are often associated with hidden characteristics that are difﬁcult to detect by usual approaches. This study aimed to estimate the incidence of serious drug-related complications by using the capture–recapture method in deﬁned geographical area.
- Methods Hospitalizations with mention of disorders related to drug of abuse were considered serious drug-related complications. We searched these cases in and crossed three sources of data: spontaneous reports of drug of abuse–related disorders called NotS (‘Notiﬁcation Spontanee’) collected by the regional addictovigilance centre, computerised hospital database Programme de Medicalisation des Systemes d’Information (PMSI) and toxicological analyses (TA) carried out for hospitalized patients.
- Results In 2007 and 2008, 1509 distinct cases were captured. After data modelling, the estimated number of psychoactive drug–related hospitalizations was 4744 (95%CI = 4060–5429). Most frequent products were opioids (34%), cannabis (19%) and cocaine (13%). ‘Multiple drugs’ were observed in 26% of cases. The incidence of serious drug-related complications in the area covered should be estimated at 5.7 (95%CI = 5.5–5.9) per thousand 15- to 64-year-old inhabitants. The exhaustiveness of sources were 0.4% (95%CI = 0.2–0.6) for NotS, 11.6% (95%CI = 10.7–12.5) for TA and 22.6% (95%CI = 21.4–23.8) for PMSI.
- Conclusions The ‘real’ number of cases far exceeds that of cases that can be identiﬁed through simple counts. In particular, it conﬁrms the underreporting and even quantiﬁes its magnitude. These results conﬁrm that drug users are frequently hospitalised and require heavy medical management. Moreover, these results show the real although limited advantage of hospitalization database in detecting drug associated disorders in epidemiological studies
