Abstract: Objective To explore the clinical practice of best evidence-based practice program for nasogastric tube insertion and evaluate its application.
Methods By referencing to Australia JBI model for evidence-based healthcare, we retrieved and summarized the best evidence for preoperative insertion of nasogastric tube, judged the position of nasogastric tube and alleviated the discomfort caused by the nasogastric tube insertion.Then we formed inspection indicators, maded baseline inspections before application of the best evidence on 29 medical staffs and 50 patients who met the inclusion criteria in department of hepatobiliary surgery, took transformative measures to boost application of the best evidence, and made post-application inspections to evlaute the effect.
Results After the application of the best evidence, the routine operation process of gastric tube insertion was improved; the awareness rate of audit indicators in medical staffs, audit indicators implementation rate, and the correct rate of gastric tube implantation were significantly improved (P<0.05 for all).
Conclusion The summarization and application of the best evidence for preoperative nasogastric tube insertion can improve medical staffs' operation level of nasogastric tube insertion,standardize the operation behaviors,reduce the patients' discomfort caused by the nasogastric tube insertion and improve their satisfaction.
