Prognostic impact of psychoactive substances use during hospitalization for intentional drug overdose.
OBJECTIVE
To assess whether current use of psychoactive substance(s) is a prognostic factor during hospitalization for intentional drug overdose (IDO).


METHODS
Current intoxication with psychoactive substance(s) [cannabis, opiate, buprenorphine, amphetamine/ecstasy, cocaine, lysergic acid diethylamide (LSD)] was identified using toxicological urinalysis in 671 patients with IDO. An IDO was a priori defined as serious if associated with one of the following events: death, hospitalization in intensive care unit longer than 48 h, respiratory support, use of vasopressive drugs, cardiac massage or dialysis.


RESULTS
Subjects positive for toxicological assays were twice as likely to present with serious IDO (OR = 1.9, 95% CI: 1.3-2.8, P = 0.001), independently from a large range of confounding factors. The risk of serious IDO was especially marked in subjects using LSD, buprenorphine or opiates.


CONCLUSIONS
Systematic investigation of substance use could be important to adapt medical management of subjects with IDO in general hospital, but also in primary care and psychiatric settings.
