Studies have shown that family members of patients in intensive care units experience high levels of anxiety. Contradictions in the results of the studies conducted regarding the effect of training on the anxiety level of such families, emphasize the necessity of employing other research methods to eliminate these ambiguities.
This study applied meta-analysis to determine the effect of training on the anxiety level of families with patients in the intensive care unit.
In order to find electronically published studies from 1990 to 2016, the articles published in journals indexed in the following databases were used: Elsevier, Scopus, ProQuest, ISI, Web of Science, PubMed, Google scholar and Cochrane. For data analysis Stata Software version 11 was used and the heterogeneity index of studies was determined through Cochran (Q) and I. Due to the heterogeneity, the random effect model was used to estimate the difference between the standardized mean of anxiety.
In this meta-analysis and systematic review article, eight articles were found to be eligible. The number of samples in the initial studies into a meta-analysis included 387 patients in the intervention group and 393 people in the control group. Standardized difference of the mean anxiety score in the intervention group was -0.329 (CI 95%: -0.756-0.099) units less than that of the control group, indicating that this effect was not statistically significant.
The results of this meta-analysis show that training will decline the anxiety level of a family with patients hospitalized in the intensive care unit, although the impact is not considerable.
研究表明，重症监护病房患者的家庭成员焦虑程度较高。关于培训对这类家庭焦虑水平影响的研究结果存在矛盾，这凸显了采用其他研究方法来消除这些模糊性的必要性。
本研究应用荟萃分析来确定培训对重症监护病房患者家庭焦虑水平的影响。
为了查找1990年至2016年电子发表的研究，使用了以下数据库索引期刊上发表的文章：爱思唯尔、Scopus、ProQuest、ISI、科学网、PubMed、谷歌学术和考克兰。数据分析使用Stata软件11版，并通过科克伦（Q）和I统计量确定研究的异质性指数。由于存在异质性，采用随机效应模型来估计焦虑标准化均值之间的差异。
在这篇荟萃分析和系统评价文章中，发现有8篇文章符合条件。纳入荟萃分析的初始研究样本量包括干预组387例患者和对照组393人。干预组平均焦虑评分的标准化差异比对照组低-0.329（95%CI：-0.756-0.099）个单位，表明这种效果在统计学上不显著。
这项荟萃分析的结果表明，培训将降低重症监护病房住院患者家庭的焦虑水平，尽管影响并不显著。
