Occupational exposure to sharps and splashes pose a major hazard among health care workers (HCWs); so knowledge and awareness regarding sharps/splashes by blood and potentially infectious body fluids (BBF) is a must. Hence, the study was done to assess the extent of knowledge of the staff and using awareness classes and hands on practice as a model to increase awareness as well as prevention.
This prospective interventional cohort study, using before - after trial, was conducted in a Level I trauma care centre. All cadres of HCWs were enrolled randomly into 5 different groups of 15 each. This study was conducted in 2 phases - interactive classes and hands on practice (Phase I) and questionnaire assessment and work area observation (phase II). This was repeated twice and the final outcome was analysed. A systematic level of grading was used to assess the improvement.
It was observed that Group 1 (doctors) and group 2 (nurses) had the maximum knowledge about such exposures and its prevention compared to the other groups (groups 3, 4 and 5) during the initial assessment (Phase I). The remaining groups showed a major improvement after the 2(nd) assessment, though their knowledge was poor in the beginning. Groups 1and 2 showed 32% and remaining groups showed a 25% improvement in voluntary reporting after the second assessment (Phase II).
Awareness classes and hands on practice are indeed useful in generating knowledge about sharps/ splashes. Certain incentives given at right time can improve it further.
医护人员职业暴露于锐器和飞溅物中是一个重大危害;因此,了解血液和潜在感染性体液(BBF)导致的锐器/飞溅物相关知识并提高意识是必不可少的。因此,开展本研究以评估工作人员的知识水平,并以提高认识和预防为目的,采用培训课程和实际操作作为模型。
本前瞻性干预队列研究采用前后试验设计,在一级创伤护理中心进行。所有医护人员干部被随机分为5个不同的组,每组15人。本研究分两个阶段进行——互动课程和实际操作(第一阶段)以及问卷调查评估和工作区域观察(第二阶段)。重复进行两次,并分析最终结果。采用系统的评分等级来评估改进情况。
在初始评估(第一阶段)期间观察到,与其他组(第3、4和5组)相比,第1组(医生)和第2组(护士)对这类暴露及其预防的知识掌握得最多。其余组在第二次评估后有了很大改进,尽管他们一开始知识掌握较差。在第二次评估(第二阶段)后,第1组和第2组的自愿报告率提高了32%,其余组提高了25%。
培训课程和实际操作确实有助于增加对锐器/飞溅物的知识了解。适时给予一定激励可进一步提高效果。
