基于关联规则下老年衰弱住院患者跌倒造成伤害的危险因素分析

Analysis of risk factors of fall injury in elderly patients with infirmity based on association rules

目的分析老年衰弱住院患者发生跌倒的现状,找出跌倒造成伤害的危险因素,为避免或减少老年衰弱住院患者在住院期间跌倒所造成的伤害提供参考依据。方法运用数据挖掘的方法,对辽宁省人民医院2017年1月1日至2020年4月30日上报的56例发生跌倒的老年衰弱住院患者的数据进行分析。通过Apriori算法进行关联性分析,使用χ^(2)检验进行有效性评定,再根据相关专业知识进行分析。结果最终获取与老年衰弱住院患者跌倒造成伤害的强关联规则6项,分别为睡眠质量差、活动能力差、服用易致跌倒药物、跌倒时状态为移位、患有脑血管疾病、自我照顾能力受限。结论使用关联性分析可挖掘出老年衰弱住院患者跌倒造成伤害的有价值的关联规则,并重视其强关联规则,为防范或减少老年衰弱住院患者跌倒所造成的伤害提供临床干预依据。
