Background
Bolus nasogastric tube feeding is common. Unsafe practices such as failure to confirm tube placement can result in death. It is vital to ensure that nurses are adopting safe practices.Objective
To evaluate nurses鈥?practices on bolus nasogastric feeding relating to verification of tube placement, management of gastric residual volume, and response to complications during feeding.
Design
Cross-sectional, self-administered survey using clinical scenarios.
Setting and participants
All nurses who worked in the general wards in a tertiary hospital in August 2008.
Methods
We developed six clinical scenarios to describe common clinical situations in nurses鈥?daily practices. Participants were instructed to choose the responses that best reflected their practices, and to return the completed questionnaires to the study member present.
Results
The survey participation rate was 99.5%(1203 nurses). Seventy-six percent would choose two or more methods to verify placement when they were in doubt. Percentage of hydrogen (pH) testing was the most common first method of checking tube placement. The second and third self-reported methods were auscultation and the bubble test. Few chose radiography to confirm tube placement. When the aspirate was pH 7, and in the presence of positive auscultation, most participants would take further steps to confirm placement. There were variations in the nurses鈥?responses on managing the gastric residual volume, with 78.1%indicating that they would return the aspirate. Most nurses lacked the knowledge to effectively manage patients鈥?distress during tube feeding.
Conclusions
The findings showed that the majority of participants reported that they would exercise due caution by taking additional measures to check tube placement when in doubt. The practice gaps identified in the study highlighted a need to realign our care to best practices. Following the study, we revised the institution's guideline, reinforced specific safety precautions on nasogastric feeding, and incorporated clinical scenarios in our training.
