目的：探讨新入院老年精神分裂症患者入住开放式与封闭式病房的意外风险状况，为开展有针对性的护理干预提供依据。方法将90例新入院老年精神分裂症患者随机分为两组，研究组入住开放式病房，对照组入住封闭式病房；采用跌倒、噎食、攻击、自杀、出走5个风险因素评估量表及护士用住院病人观察量表评估两组患者的风险状况。结果两组患者中有攻击风险者占40．0％，有自杀风险者占24．4％；研究组跌倒、噎食发生率显著低于对照组（P＜0．05），出走发生率显著高于对照组（P＜0．01）。两组护士用住院病人观察量表各因子评分比较差异均无显著性（P＞0．05）。结论对新入院老年精神分裂症患者加强风险评估管理，是预防患者住院期间发生意外事件的重要措施。“,”Objective To explore unexpected risks among newly admitted senile schizophrenics in open-and close-door ward in order to provide basis for developing purposeful nursing intervention .Methods Ninety newly admitted senile schizophrenics were randomly assigned to two groups ,research group was admitted in open-door ward and control group close-door ward ;Risk status was assessed with 5 Risk Fac-tor Assessment Scale and Nurses’ Observation Scale for Inpatient Evaluation (NOSIE) .Results Patients with aggression risk of two groups made up 40 .0% ,ones with suicide risk did 24 .4% ;fall and choke inci-dence were significantly lower (P<0 .05) and abscondence was higher (P0 .05) .Conclu-sion Enhancing risk assessment in newly admitted senile schizophrenics is important safeguard for inpa-tients’ safety .
