abstract="BACKGROUND: Repeated drug overdose is a major risk factor for suicide. Data are lacking on the effect of psychiatric intervention on preventing repeated drug overdose. AIMS: To investigate whether psychiatric intervention was associated with reduced readmission to emergency centres due to drug overdose. <br><br>METHOD: Using a Japanese national in-patient database, we identified patients who were first admitted to emergency centres for drug overdose in 2010-2012. We used propensity score matching for patient and hospital factors to compare readmission rates between intervention (patients undergoing psychosocial assessment) and unexposed groups. <br><br>RESULTS: Of 29 564 eligible patients, 13 035 underwent psychiatric intervention. In the propensity-matched 7938 pairs, 1304 patients were readmitted because of drug overdose. Readmission rate was lower in the intervention than in the unexposed group (7.3% v. 9.1% respectively, P<0.001). <br><br>CONCLUSIONS: Psychiatric intervention was associated with reduced readmission in patients who had taken a drug overdose.
