Emergency department health care workers frequently provide care to patients who are in unstable condition, bleeding, or in a crisis situation. To identify the variables described in the Health Belief Model affecting health care workers' compliance with practices and devices believed to reduce exposure to patients' blood, the staff of a level II trauma center were surveyed for knowledge, compliance, and training regarding universal precautions.
Fifty-three health care workers responded to an anonymous, self-report, 50-item questionnaire. Significant differences in mean scores were determined by use of a two-tailed t test.
Health care workers estimated they were most likely to perform handwashing after contact with body fluids and to wear gloves if contact with blood was anticipated. The most common obstacles to compliance with universal precautions were lack of time, patients perceived to be at lower risk for HIV or hepatitis B infections, and interference with technical skills. Health care workers with more than three perceived obstacles to universal precautions were less likely to use gloves (p < 0.05) if contact with blood was anticipated. Health care workers with a higher number of training experiences in universal precautions were more likely to use gloves if contact with blood was anticipated (p < 0.05) and less likely to recap a needle after giving an intravascular injection (p < 0.05), drawing a blood gas sample (p < 0.05), or injecting medication into an intravenous line (p < 0.05).
The application of the Health Belief Model to this problem suggests that an integrated approach is appropriate. Such an approach should incorporate engineering controls, cognitive approaches, behavior modification strategies, and training experiences to improve skills and dexterity.
急诊科医护人员经常为病情不稳定、出血或处于危急情况的患者提供护理。为了确定健康信念模型中描述的影响医护人员遵守被认为可减少接触患者血液的操作和设备的变量,对一家二级创伤中心的工作人员进行了关于普遍预防措施的知识、遵守情况和培训的调查。
53名医护人员回答了一份50项的匿名自填问卷。使用双尾t检验确定平均得分的显著差异。
医护人员估计,他们最有可能在接触体液后洗手,并且如果预计会接触血液则会戴手套。遵守普遍预防措施最常见的障碍包括时间不足、患者被认为感染艾滋病毒或乙型肝炎的风险较低以及对技术技能的干扰。认为普遍预防措施存在三个以上障碍且预计会接触血液的医护人员使用手套的可能性较小(p<0.05)。接受普遍预防措施培训经验较多的医护人员在预计会接触血液时使用手套的可能性较大(p<0.05),在进行血管内注射后(p<0.05)、采集血气样本时(p<0.05)或向静脉输液管内注射药物时(p<0.05)回套针头的可能性较小。
将健康信念模型应用于这个问题表明,综合方法是合适的。这种方法应包括工程控制、认知方法、行为改变策略以及培训经验,以提高技能和灵活性。
