Knowledge and practices of isolation precautions among nurses in Jordan

Implementation of isolation precautions from the Centers for Disease Control and Prevention (CDC) has been justified through research and clinical evidence. However, nurses' understanding and compliance with these precautions is still unknown. The aim of this study was to assess nurses' knowledge and practices in relation to isolation precautions in Jordan.

A cross-sectional, descriptive design was used. The study took place in 8 hospitals in Jordan. A self-reported questionnaire and an observational checklist were developed based on the CDC (2007) isolation precautions guidelines.

A total of 247 questionnaires were returned out of 400, for a response rate of 61.7%. The results show that most nurses (90%) have good knowledge of isolation precautions. However, only 65% of nurses reported good compliance with isolation precautions. The results of a t test revealed that nurses with Bachelor's degrees perform better in knowledge examinations than nurses with 2-year diplomas (P < .001). However, there was no significant difference in knowledge and self-report practices scores based on nurses' previous training and existence of isolation guidelines in their units or wards (P > .05). The results of the checklists confirm that there is a low compliance with standard isolation practice. In addition, the checklist shows that a high percentage of units and wards do not use isolation signs (46.4%) and posters (34.5%).

This study revealed that educating nurses about isolation is not enough strategy to improve their compliance. It is important to adapt other strategies, such as supporting nurses by giving them a manageable workload, and providing more supplies and reminders of isolation precautions in the hospitals.
