Human immunodeficiency virus (HIV) continues to be a significant public health concern for adolescents and young adults. Since 2006, the Centers for Disease Control and Prevention has recommended more aggressive routine screening for HIV for patients presenting to the emergency department (ED). Our objectives were to design and validate a survey of physician barriers toward the use of rapid HIV testing in the pediatric ED and then to use this validated tool to conduct a national survey of pediatric emergency practitioners' attitudes toward rapid HIV testing in the ED.
Survey design and initial validation steps were conducted with a panel of health care practitioners familiar to HIV testing. Several variables were identified as possible barriers toward rapid HIV testing. The survey was sent via electronic software to a national sample of pediatric emergency practitioners over 2 listservs. The previously identified variables were evaluated by factor analysis for internal consistency and homogeneity, and confirmatory factor analysis was conducted via promax and varimax rotation. All factor analyses were conducted using Stata software. Once the validation was complete, the surveys were sent to groups of pediatric emergency practitioners who had previously identified as having rapid HIV testing available in their EDs. Standard descriptive statistics were used, and group differences were evaluated with t test and χ(2) test.
Four factors were identified during the validation process as being the most important barriers for rapid HIV testing in the pediatric ED: self efficacy, familiarity, external barriers, and a previously unidentified factor, which we interpreted as related to barriers to the specific environment of one's own ED. A total of 80 participants returned the final, validated survey. The participants came from 9 different pediatric emergency medicine groups (5 in areas of low rates of HIV infection, 4 in areas of high rates of HIV infection). Self-reported rates of testing were not different based on HIV infection rate in the community or the respondent's level of training. High testing was more common when a guideline was reported (39%) than when it was not (13.3%; difference, 25.7%; 95% confidence interval, 2.9%-48.5%). Of the 4 factors identified, we found statistically significant differences in scores on all 4 factors between high versus low testers, with high testers disagreeing more strongly with the various barrier questions proposed. We found no difference in the factor scores between areas of high versus low HIV infection rates.
Our results suggest that several factors related to perceived provider barriers are associated with rates of HIV testing in the ED and that personal factors (eg, level of training) and community HIV prevalence were not associated with rates of testing. Our results confirm what has been speculated by numerous authors and provide data to inform efforts to improve compliance with national recommendations for increased testing.
人类免疫缺陷病毒(HIV)仍然是青少年和青年群体中一个重大的公共卫生问题。自2006年以来,美国疾病控制与预防中心建议对前往急诊科(ED)就诊的患者进行更积极的HIV常规筛查。我们的目标是设计并验证一项关于儿科急诊科医生在使用快速HIV检测方面所面临障碍的调查,然后使用这个经过验证的工具对儿科急诊从业者在急诊科对快速HIV检测的态度进行全国性调查。
调查设计和初始验证步骤由一组熟悉HIV检测的医疗从业者进行。确定了几个可能成为快速HIV检测障碍的变量。该调查通过电子软件发送给两个邮件列表上的全国儿科急诊从业者样本。通过因子分析评估先前确定的变量的内部一致性和同质性,并通过promax和varimax旋转进行验证性因子分析。所有因子分析均使用Stata软件进行。验证完成后,将调查问卷发送给之前确定其急诊科可进行快速HIV检测的儿科急诊从业者群体。使用标准描述性统计方法,并通过t检验和χ²检验评估组间差异。
在验证过程中确定了四个因素是儿科急诊科快速HIV检测的最重要障碍:自我效能感、熟悉程度、外部障碍,以及一个先前未识别的因素,我们将其解释为与自身急诊科特定环境的障碍相关。共有80名参与者返回了最终经过验证的调查问卷。参与者来自9个不同的儿科急诊医学组(5个位于HIV感染率低的地区,4个位于HIV感染率高的地区)。根据社区的HIV感染率或受访者的培训水平,自我报告的检测率没有差异。当报告有指南时,高检测率更为常见(39%),而没有指南时则较低(13.3%;差异为25.7%;95%置信区间为2.9% - 48.5%)。在确定的4个因素中,我们发现高检测者与低检测者在所有4个因素的得分上存在统计学显著差异,高检测者对提出的各种障碍问题的反对更为强烈。我们发现HIV感染率高的地区和低的地区在因子得分上没有差异。
我们的结果表明,与感知到的提供者障碍相关的几个因素与急诊科的HIV检测率相关,而个人因素(如培训水平)和社区HIV流行率与检测率无关。我们的结果证实了许多作者的推测,并提供数据以指导提高对增加检测的国家建议的依从性的努力。
