Effects of Using Perineal Underwear on Discomfort and Shame in Angiography Patients.

The purpose of this study is to develop and apply a type of perineal underwear that protects the patient's physical privacy and to examine its effects on perineal discomfort and shame. This study collected primary data from 44 patients who visited Kyung Hee University hospital in Seoul city and were admitted to the neurosurgery ward to undergo angiography between 7 August 2017, and 30 April 2018. In this quasi-experimental study with a nonequivalent control group posttest-only design, participants were divided into an experimental group (n = 22) and a control group (n = 22). The control group used conventional protection, which involved wearing padding around the perineum, while the experimental group wore the perineal underwear developed in this study. The underwear group showed a significantly lower degree of shame (Z = -5.39, p < 0.001) and perineal discomfort (Z = -5.88, p < 0.001) than the padding group. In the padding group, women felt significantly more shame than men did (Z = -2.48, p = 0.013). The use of the perineal underwear developed in this study significantly reduced the degree of shame and perineal discomfort in patients undergoing angiography. Such perineal underwear could also be useful for protecting patients' privacy during perineal examinations.
