Anxiety in gastroscopies: Comparison of two nursing interventions in endoscopy without sedation
Abstract
There is a disparity between nurses about the ideal role of nurses in endoscopies without sedation. Some nurses think that providing information to the patient is sufficient to reduce anxiety and improve tolerance and satisfaction, while others believe that behavioral training and positive reinforcement during the procedure are also necessary.
The objectives of this study were to test the differences that are produced in the patient’s state of anxiety between the two types of nursing intervention, as well as in the patient’s tolerance and satisfaction.
The study included 109 outpatients who had an endoscopy without sedation. They were divided into two groups, the experimental group who received nursing support based on information, behavioral training and positive reinforcement during the procedure, and the control group, who received nursing support based solely on information provided about the procedure. Anxiety was evaluated with a STAI-state test and with psychophysiological parameters at different moments during the process. The data was analyzed with repeated measures of analysis of the variance, which resulted in the following: the STAI score decreased more in the experimental group. Tolerance was greater in the experimental group, patient satisfaction was equal in the two groups, and the difference in the levels of systolic and diastolic blood pressure and heart rate was equal in the two groups.
Experimental investigations are useful in nursing to obtain scientific evidence about the ideal clinical practice. It is possible to improve the tolerance of gastroscopy and reduce anxiety due to the procedure, with the intervention of the nurses centered in the cognitive and behavioral aspects of the person.
