Introduction Schizophrenia increases the risk of offending. Recidivism rates are significant. Literature doesn't provide recidivism risk factors specific to patients with schizophrenia independently of the offenses' types. Objective Identifying recidivism risk factors in schizophrenia patients independently of the offenses' types. Methods We conducted a case-control study. All included patients were admitted, at least once, to the forensic psychiatry unit in Razi Hospital between January 1st, 1985 and December 31st, 2014 after a decision of irresponsibility by reason of insanity. All those who reoffended during this period were considered as cases. Univariate and multivariate analyses were performed to identify recidivism risk factors. Results We included 25 cases and 38 controls. Eight recidivism risk factors were identified. Living in poor urban neighborhoods (P = 0.023; OR = 4.86), having been unemployed (P = 0.042; OR = 2.18) and not having lived with the family (P = 0.039; OR = 1.36) after discharge were considered as risk factors. The same applied to alcohol (P = 0.026; OR = 4.89) and cannabis use disorders (P = 0.018; OR = 6.01). A hospitalization shorter than 6 months multiplied the risk by 1.79 (P = 0.046). A combination of conventional antipsychotics (P = 0.023; OR = 4.81) and a poor adherence to treatment (P = 0.001; OR = 10.42) were considered as recidivism risk factors too. Conclusions All eight recidivism risk factors are dynamic. This makes recidivism prevention conceivable. Measures involving the patient, the health care system, patients' families, society and the government should be undertaken.

Background Many studies have established a correlation between the increase of homicide rates, and economic crises and rapid social changes following historical events. We propose to analyse the impact of the Tunisian Revolution on homicide rates in Tunisia in a clinical population. Methods We conducted a retrospective comparative study of all individuals who commited an homicide and were admitted, at least once, to the forensic psychiatry unit in Razi Hospital between January 1st, 2004 and December 31st, 2018 after a decision of irresponsibility by reason of insanity. Results The number of homicides committed by the individuals with mental illness included in our study was multiplied by a factor of 1.3 after the revolution, with a prevalence of 11.0% between 2004 and 2011, compared to a prevalence of 14.7% during the period 2011–2018. No significant difference was noted between the two groups regarding the socio-demographic characteristics or the characteristics of the act committed. Conclusion Our results highlighted that political and socio-economic crises following the Tunisian revolution significantly contributed to an increase of homicide rates in people with severe mental illness. Thus, macro-level socioeconomic determinants would be important to consider in homicide prevention strategies.
