Abstract

AIM

To examine the association between the hospitalization time and fall incidence.

DESIGN

A secondary analysis using the Dryad Digital Repository public database.

METHODS

Data were extracted from the Fukushima Medical University Hospital cohort study between August 2008 and September 2009. The final analytic sample included 8,598 participants, 156 of who fell. The risk of fall incidents according to hospitalization time was estimated using logistic proportional hazards models, and restricted cubic splines with four knots model were developed.

RESULTS

The median hospitalization time was 9.00 (4.00, 17.00) days. The incidence of falls was 1.81% (N = 156). A U-shaped association between the hospitalization time and fall incidence, with an inflextion point of 8 days. We found a decreasing fall incidence as the hospitalization time increased from 0 to 8 days (OR 0.72 [0.62 ~ 0.83], p < .001); beyond 8 days, the fall incidence increased as the hospitalization time increased (OR 1.06 [1.04 ~ 1.09]).

摘要

目的

探讨住院时间与跌倒发生率之间的关系。

设计

利用 Dryad Digital Repository 公共数据库进行二次分析。

方法

数据来自 2008 年 8 月至 2009 年 9 月福岛医科大学医院的队列研究。最终分析样本包括 8598 名参与者，其中 156 人跌倒。使用逻辑比例风险模型和带有四个结的限制立方样条模型来估计住院时间与跌倒事件风险之间的关系。

结果

住院时间的中位数为 9.00（4.00，17.00）天。跌倒发生率为 1.81%（N=156）。住院时间与跌倒发生率之间呈 U 形关系，拐点为 8 天。我们发现，随着住院时间从 0 天增加到 8 天，跌倒发生率逐渐下降（OR 0.72 [0.62~~0.83]，p<0.001）；超过 8 天后，随着住院时间的增加，跌倒发生率增加（OR 1.06 [1.04~~1.09]）。
