摘　　要：针对医联体平台中实际双向转诊过程存在转诊安排不及时,患者不满意等问题,设计了一种基于随机森林的双向转诊智能决策方法。该方法选取影响转诊的5个主要因素,建立了包括床位数、床位使用率、疾病治愈率、治疗费用、相距距离五大指标的智能转诊评分模型;然后利用大数据和随机森林的方法对主要因素进行分析,以分数的形式来衡量待转诊医院适合度。实践效果表明,基于这5个主要因素的预测可以罗列出多种转诊方案,为转诊安排精准化决策提供一种依据,从而提高转诊效率。Aiming at the problems in the actual two-way referral process of medical alliance platform,such as untimely referral arrangement and unsatisfactory patients,a two-way referral intelligent decision method based on random forest was designed.In this method,five main factors affecting referral were selected and an intelligent referral scoring model was established,including the number of beds,bed utilization rate,disease cure rate,treatment cost and distance.Then,big data and random forest methods are used to analyze the main factors and measure the suitability of the hospital to be referred to in the form of scores.The practical results show that predictions based on these five main factors can list a variety of referral plans,provide a basis for accurate decision-making on referral arrangements,and improve the efficiency of referrals.
