Alternatives to chemical and physical restraints exist. They are as complex as individual voice warning systems or as simple as push-button combination locks. An electronic security system can improve the quality of life for alert, oriented patients (and their families) who share a unit with confused, wandering patients. An electronic security system can be effective in alerting staff to the presence of a monitored patient in a restricted area.
存在化学和身体约束的替代方法。它们既可以像个人语音警报系统一样复杂，也可以像按钮密码锁一样简单。电子安全系统可以改善与神志不清、四处游荡的患者共用一个单元的警觉、意识清醒的患者（及其家属）的生活质量。电子安全系统可以有效地提醒工作人员注意受监控患者出现在限制区域。
