Psychotic patients are 10 to 20 times more likely to commit homicide than persons in the general population. Internationally, the incidence of homicides committed by psychotic defendants is 0.02-0.36 per 100.000 inhabitants. So far, no-one has determined the nature and incidence of homicide by individuals with a psychotic disorder in the Netherlands.
To describe the nature and incidence of homicides committed by people with a psychotic disorder in the Netherlands in the period 2000-2006.
We analysed the forensic mental health reports of all Dutch nationals suspected of committing homicide and found to be suffering from a psychotic disorder at the time of the offence.
According to the mental health reports, in the period under study 61 homicides were committed by people with a psychotic illness (8.7 annually), the average rate being 0.05 per 100,000. The majority of suspects did not have a violent criminal past and were not receiving treatment at the time of the crime.
Homicide committed by psychotic patients is relatively rare in the Netherlands, but it does occur. Early, continuous treatment of psychotic illness might help to prevent patients with a psychotic disorder from committing homicide.
精神病患者实施杀人行为的可能性比普通人群高10至20倍。在国际上，每10万居民中，精神病被告实施杀人行为的发生率为0.02 - 0.36。到目前为止，还没有人确定荷兰患有精神疾病的个体实施杀人行为的性质和发生率。
描述2000年至2006年期间荷兰患有精神疾病的人实施杀人行为的性质和发生率。
我们分析了所有被怀疑实施杀人行为且在犯罪时被认定患有精神疾病的荷兰国民的法医精神健康报告。
根据精神健康报告，在研究期间，有61起杀人行为是由患有精神疾病的人实施的（每年8.7起），平均发生率为每10万人0.05起。大多数嫌疑人过去没有暴力犯罪史，且在犯罪时未接受治疗。
在荷兰，精神病患者实施的杀人行为相对罕见，但确实存在。对精神疾病进行早期、持续的治疗可能有助于防止患有精神疾病的患者实施杀人行为。
