Noise levels in the dialysis unit and its relationship with sleep quality and anxiety in patients receiving HD: A pilot study

Abstract

Introduction HD unit is a noisy environment for patients, and noise can affect anxiety levels and sleep quality. Methods The aim of the study is to determine noise level, the relationship between noise levels, and sleep quality and anxiety in patients in HD unit. A descriptive and observational study design was used. Three Benetech GM1351 manual sound-level meters were used to measure noise. A patient information form, the State Anxiety Inventory, and the modified Post-Sleep Inventory were used for data collection. Results The noise range detected in the HD unit ranges from 48.40 to 72 dB(A). Our findings show that patients in the HD unit are exposed to high noise levels and the noise significantly negatively impacts quality of sleep and anxiety level of the patients. Conclusions It is important to be aware that HD patients are constantly exposed to high levels of noise and to plan nursing interventions to reduce this noise level.
