德尔菲法构建慢性苯中毒患者医院感染风险评估量表及其效用

Development of risk assessment scale for nosocomial infection of patients with chronic benzene poisoning using the Delphi technique

    摘要
  • 摘要:
    目的 编制适合慢性苯中毒患者医院感染风险的评估量表, 为慢性苯中毒患者提供医院感染风险评估的工具。
    方法 根据课题前期对苯中毒患者医院感染的危险因素的分析结果, 应用德尔菲法形成慢性苯中毒患者医院感染风险评估量表。选取100例慢性苯中毒患者进行调查, 对量表信度、效度进行评价; 再将量表应用于72例慢性苯中毒患者进行感染风险评估, 其中试验组36例患者根据量表确定的风险等级给予分级预防, 对照组36例患者给予常规预防感染措施, 比较两组的感染率、例次感染率。
    结果 2轮咨询专家积极系数各为100%, 专家权威系数为0.76, 第二轮Kendall协调系数为0.729(P < 0.05);最终形成的慢性苯中毒患者医院感染风险评估量表包括3个维度, 分别为患者基本情况、检查和干预措施, 以及10个条目。探索性因素分析共提取3个公共因子, 分别为诊断指标因子、干预因子与患者个体因子, 可解释总变异的56.895%;Cronbach's α值为0.736。试验组患者感染率、例次感染率均低于对照组, 差异有统计学意义(P < 0.05)。
    结论 该量表具有良好的信度和效度, 可作为评价慢性苯中毒患者医院感染风险的工具, 对其运用能更好预防患者医院感染的发生。

     

    Abstract:
    Objective  To build an assessment scale for estimation of nosocomial infection risk of patients with chronic benzene poisoning.
    Methods  Based on the nosocomial infection risk factors of patients with chronic benzene poisoning obtained in the early stage, a risk assessment scale for nosocomial infection of patients was studied with Delphi technique. Totally 100 patients with chronic benzene poisoning were selected to evaluate the reliability and validity of the scale. Then the scale was applied to assess the risk of nosocomial infection of 72 patients with chronic benzene poisoning. These patients were divided into experimental and control groups; 36 cases in the experimental group were given graded prevention according to the risk grade determined by the scale and 36 cases in the control group were given routine preventive infection measures. The incidence of infection and secondary infection in these two groups were compared.
    Results  The positive coefficient of consultation experts was 100% for both first and second round consultations; the expert authority coefficient was 0.76; the Kendall harmony coefficient at second round consultation was 0.729 (P < 0.05). The three dimensions with 10 items in this scale were basic condition of patients, medical examination and intervention measures. The exploratory factor analysis showed that three common factors were factors of diagnostic index, intervention and individual, which explained 56.89% of total variation and the Cronbach's α coefficient was 0.736. The patients in experimental group had statistically significant lower incidence of both infection and secondary infection(P < 0.05).
    Conclusion  This scale has a good reliability and validity, it could be used to evaluate the risk of nosocomial infection of patients with chronic benzene poisoning. The use of this scale and adoption of corresponding measures could effectively prevent nosocomial infection.
