Efficacy of a Nasogastric Tube Educational Intervention for Nursing Staff

We performed a single-center teaching intervention with nursing providers on nasogastric tube (NG tube) clinical practice. The initial purpose of this study was the validation of whether the training was sufficient enough to be retained at a later time point.

We performed a prospective pre-post study examining participants' knowledge before, immediately after, and 4 weeks after training in NG tube management. Training was delivered in face-to-face classroom sessions. Knowledge was assessed using a multiple-choice test (pretest, posttest #1and #2).

A total of 137 nursing providers participated in the training intervention. Immediately after training (posttest #1) and again 4 weeks later (posttest #2), participants overwhelmingly recalled and retained the knowledge of NG tube management as compared to pretest results. Paired t-tests showed each participant increased their test score from pretest to posttest #1, t (134) = 12.64, P = .0001. Similarly, participants who took posttest #2 significantly improved their scores from the pretest to posttest #2, t (71) = 10.629, P < .0001. Secondary analysis showed that the NG tube management comfort level and age of provider were not significant in predicting test results. However, years of professional experience and frequency of NG tube care were significant predictors for higher test scores.

To minimize the risk of NG tubes for patients, it is critical to follow clinical guidelines. This study shows that teaching interventions for providers to increase knowledge on NG tubes are beneficial. In addition, the knowledge is retained at later time points.
