The objective of this study was to assess the knowledge on pulse oximetry among health care professionals involved in pediatric care.
A multiple-choice questionnaire was distributed to 505 pediatric health care professionals from 19 hospitals and health centers throughout Greece. Exploratory factor analysis was performed to identify underlying factors that could explain most of the variance of the responses. The mean test and factor scores were calculated and compared between clinical settings.
The mean test score was 61.9+/-18.1%. After factor analysis, 2 distinct groups of deficits in knowledge regarding pulse oximetry were identified: 1 was interpreted as relating to practical knowledge and the other to theoretical knowledge. The mean score of the items that assessed practical knowledge was 82.7+/-12.5% and of those that assessed theoretical knowledge was 44.2+/-21.7%. Pediatricians and family practitioners, participants from level 3 institutions, and health care professionals working in ICUs scored better, particularly on the items that assessed theoretical knowledge. Logistic regression analysis revealed that only participants from level 3 institutions and those from ICUs had a greater likelihood of achieving a higher score (total score odds ratio: level 3, 2.89, ICU, 8.13; theoretical knowledge odds ratio: level 3, 3.40, ICU, 10.95).
Pediatric health care professionals have marked deficiencies in their knowledge on pulse oximetry, particularly in regard to the principles underlying the method and its limitations. Strategies that are directed at improving knowledge on pulse oximetry are urgently needed at all levels of experience in pediatric care.
本研究旨在评估参与儿科护理的医护人员对脉搏血氧仪的了解程度。
向希腊 19 家医院和医疗中心的 505 名儿科医护人员发放多项选择问卷。采用探索性因子分析确定可解释大部分反应差异的潜在因素。计算并比较了不同临床环境下的平均测试和因子分数。
平均测试得分为 61.9±18.1%。经过因子分析，确定了脉搏血氧仪知识缺陷的 2 个不同组别：一组可解释为与实践知识相关，另一组可解释为与理论知识相关。评估实践知识的项目平均得分为 82.7±12.5%，评估理论知识的项目平均得分为 44.2±21.7%。儿科医生和家庭医生、来自 3 级机构的参与者以及在 ICU 工作的医护人员得分更高，特别是在评估理论知识的项目上。逻辑回归分析显示，只有来自 3 级机构的参与者和来自 ICU 的参与者更有可能获得更高的分数（总分比值比：3 级机构，2.89；ICU，8.13；理论知识比值比：3 级机构，3.40；ICU，10.95）。
儿科医护人员在脉搏血氧仪知识方面存在明显的缺陷，特别是在该方法的原理及其局限性方面。在儿科护理的各级经验中，都迫切需要制定策略来提高对脉搏血氧仪的了解。
