Universal precautions have been recommended to limit occupational exposure to the human immunodeficiency virus (HIV) and other infectious agents, but whether these recommendations have been incorporated into routine practice has not been demonstrated.
Using a one-group, before-after design, we assessed the knowledge and attitudes concerning universal precautions and the level of compliance with these recommendations. The health care professionals had various levels of training and worked in an ambulatory practice with a high rate of HIV. A total of 195 procedures involving potential exposure to various body fluids were observed.
No improvement in compliance with recommended precautions was observed following a didactic educational program for either latex glove use (44 percent versus 49 percent, chi 2 less than 1, P greater than 0.2) or appropriate use of hand washing (34 percent versus 47 percent, chi 2 = 3.38, P = 0.07). Faculty demonstrated the lowest levels of adherence to universal precautions. While knowledge of precautions was high, staff members at all levels overestimated their own compliance with these recommendations.
Although the number of observations limits the conclusions, the results suggest that the basic protective measures included in universal precautions are not being routinely applied in ambulatory medical practice. Furthermore, didactic educational programs might not be sufficient to improve compliance. Finally, faculty in training programs should monitor their own compliance with universal precautions because of their responsibilities as role models for physicians in training.
已建议采取普遍预防措施以限制职业性接触人类免疫缺陷病毒(HIV)和其他传染原,但这些建议是否已纳入常规实践尚未得到证实。
采用一组前后对照设计,我们评估了关于普遍预防措施的知识和态度以及对这些建议的遵守程度。医疗保健专业人员接受过不同程度的培训,在一个HIV感染率很高的门诊机构工作。共观察了195例涉及可能接触各种体液的操作。
在开展关于使用乳胶手套(44%对49%,卡方值小于1,P大于0.2)或正确洗手(34%对47%,卡方值=3.38,P = 0.07)的讲授式教育项目后,未观察到遵守推荐预防措施方面的改善。教员遵守普遍预防措施的水平最低。虽然对预防措施的知晓率很高,但各级工作人员都高估了自己对这些建议的遵守情况。
尽管观察数量限制了结论,但结果表明普遍预防措施中包含的基本保护措施在门诊医疗实践中未得到常规应用。此外,讲授式教育项目可能不足以提高遵守率。最后,培训项目中的教员应监测自己对普遍预防措施的遵守情况,因为他们对接受培训的医生起着榜样作用。
