To evaluate the sustainability and effectiveness of training as an intervention to improve the knowledge, attitude and practices of hospital workers on health care waste management.
We conducted this quasi-experimental study in two tertiary care teaching hospitals in Rawalpindi in October 2013. Training, practical demonstrations and reminders on standard waste management were given to 138 hospital workers in one hospital and compared with 137 workers from the control hospital. We collected data 18 months after intervention through a structured questionnaire to assess the impact of the intervention. We used paired t-test to compare the scores on knowledge, attitude and practices at baseline and first follow up and final impact assessment. Chi square test was used to compare group variables between intervention and control groups.
After 18 months since intervention the mean scores on knowledge attitude and practices differed statistically significantly since baseline and intervention group had statistically significantly better knowledge positive attitudes and good health care waste management practices (p < 0.001). Health care and sanitary workers in intervention group scored statistically significantly higher (p < 0.001).
Trainings of health and sanitary workers on health care waste management guidelines were sustainable among the intervention group after 18 months which shows the positive impact of our intervention. It is recommended that the trainings as intervention be included in the overall policies of the public and private sector hospitals in Pakistan and other similar settings.
评估作为一种干预措施的培训在提高医院工作人员对医疗废物管理的知识、态度和实践方面的可持续性和有效性。
2013年10月，我们在拉瓦尔品第的两家三级护理教学医院开展了这项准实验研究。对一家医院的138名医院工作人员进行了标准废物管理方面的培训、实践演示和提醒，并与对照医院的137名工作人员进行比较。干预18个月后，我们通过结构化问卷收集数据，以评估干预的影响。我们使用配对t检验来比较基线、首次随访和最终影响评估时在知识、态度和实践方面的得分。使用卡方检验来比较干预组和对照组之间的组变量。
干预18个月后，知识、态度和实践方面的平均得分与基线相比有统计学显著差异，干预组在知识、积极态度和良好的医疗废物管理实践方面有统计学显著更好的表现（p < 0.001）。干预组的医疗和卫生工作人员得分在统计学上显著更高（p < 0.001）。
对卫生和卫生工作人员进行医疗废物管理指南培训在干预组18个月后具有可持续性，这表明我们的干预产生了积极影响。建议将作为干预措施的培训纳入巴基斯坦及其他类似环境中公立和私立部门医院的总体政策。
