In England, forensic psychiatric hospital services are provided at three security levels: high, medium and low. All are publicly funded and similarly regulated, but medium and low secure services are provided in the private and charitable (PCS) sector as well as the National Health Service (NHS). Originally, medium secure hospital services were conceived as for up to 2 years' inpatient stay, but numbers of longer stay patients have been rising. Little is known about their characteristics or whether they differ between NHS and PCS settings.

NHS以及英格兰私人和慈善部门内的长期中度安全患者的比较

在英格兰，法医精神病医院的服务级别分为三个安全级别：高，中和低。所有这些都是公共资助的，并且受到类似的监管，但是在私人和慈善（PCS）部门以及国家卫生服务（NHS）中提供中低安全性服务。最初，中等安全的医院服务的住院时间长达2年，但是长期住院的患者数量一直在增长。关于它们的特性，或者它们在NHS和PCS设置之间是否有所不同，鲜为人知。
