摘　　要：目的探讨良性阵发性位置性眩晕(benign paroxysmal positional vertigo,BPPV)患者复位后残余头晕的影响因素,构建列线图预测模型。方法选择2020年1月至2020年12月徐州市中心医院眩晕中心收治的BPPV患者150例,采用计算机随机数法将就诊患者分为训练组112例,验证组38例。训练组根据复位后情况分为残余头晕组43例,无残余头晕组69例,采用Logistic回归分析BPPV复位后残余头晕的影响因素,构建列线图预测模型并验证。结果残余头晕组年龄、病程>6个月、复位次数≥3次、复位后复发比例均高于无残余头晕组,差异均有统计学意义(P<0.05)。年龄、发病持续时间>6个月、复位次数≥3次是BPPV复位后残余头晕的独立危险因素,依据独立影响因素构建的列线图预测模型具有较高的区分度、准确性和临床适用性。结论年龄、病程、复位次数及复位后复发与BPPV患者复位后残余头晕密切相关。Objective At present,there lacks systematic study on the influencing factors on residual dizziness in patients with benign paroxysmal positional vertigo(BPPV)after reduction therapies.This study aims to identify such factors and introduce a nomogram prediction model.Methods Data from 150 patients with BPPV admitted to the vertigo center in our hospital from January 2020 to December 2020 were selected and divided into a training set(n=112)and a validation Set(n=38).The training set was further divided into a residual dizziness group and a nonresidual dizziness group on the basis of presence of residual dizziness after reduction.Multivariate Logistic regression was used for factors influencing post-reduction residual dizziness.Results Compared with the non-residual dizziness group,patients in the residual dizziness group were older,with longer disease duration(>6 months),higher number of reduction sessions(≥3 times)and higher recurrence rate(P<0.05),which were identified as independent risk factors for post-reduction residual dizziness.The nomogram prediction model based on these independent influencing factors demonstrated high differential accuracy and clinical applicability.Conclusions Age,duration of disease,number of reduction sessions and post-reduction recurrence are closely related to residual dizziness after reduction in BPPV.
