Effect of Music and Lighting on Anxiety During Urodynamic Study (CALM-UDS)

Effect of Environmental Factors on Patient Anxiety During Urodynamic Study: A Prospective Randomized Trial

This study is designed to evaluate the effects of environmental modifications, specifically music and lighting conditions, on anxiety in patients undergoing urodynamic study (UDS). Approximately 220 adult participants are planned to be randomly assigned to one of four intervention groups. Anxiety levels before and after the procedure will be assessed using the State-Trait Anxiety Inventory (STAI). The study aims to determine the independent and combined effects of music and lighting on patient anxiety during UDS.

Study Overview

Detailed Description

Urodynamic study (UDS) is an important diagnostic procedure for evaluating lower urinary tract dysfunction. Because UDS requires urethral and rectal catheterization, many patients experience anxiety before and during the procedure. This study is designed to evaluate whether environmental modifications, including relaxing music and dim lighting, reduce anxiety during UDS.

Approximately 220 adult participants are planned to be enrolled and randomly assigned in a 1:1:1:1 ratio to one of four groups: standard lighting without music, standard lighting with music, dim lighting without music, and dim lighting with music. Anxiety will be assessed before and after the procedure using the State-Trait Anxiety Inventory (STAI). Secondary outcome measures will include heart rate and blood pressure changes. The study will evaluate the independent and combined effects of music and lighting using a 2 × 2 factorial design.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Standard Lighting Without Music
Participants undergo urodynamic study under standard lighting without music.
Standard lighting (500 lux) during the urodynamic study.
Experimental: Standard Lighting With Music
Participants undergo urodynamic study under standard lighting while listening to relaxing instrumental music.
Standard lighting (500 lux) during the urodynamic study.
Relaxing instrumental Zen-style music played during the urodynamic study.
Experimental: Dim Lighting Without Music
Participants undergo urodynamic study under dim lighting without music.
Ambient lighting is reduced to approximately 50 lux throughout the urodynamic study to provide a dimly lit examination environment.
Experimental: Dim Lighting With Music
Participants undergo urodynamic study under dim lighting while listening to relaxing instrumental music.
Relaxing instrumental Zen-style music played during the urodynamic study.
Ambient lighting is reduced to approximately 50 lux throughout the urodynamic study to provide a dimly lit examination environment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in State-Trait Anxiety Inventory (STAI) Score
Time Frame: Immediately before and immediately after the urodynamic study
The primary outcome is the change in State-Trait Anxiety Inventory (STAI) score from before to after the urodynamic study. The STAI is a validated questionnaire used to assess anxiety, with higher scores indicating greater anxiety. The change in score will be compared between the four intervention groups.
Immediately before and immediately after the urodynamic study
