- University of British Columbia
- Brief Summary
This is a prospective, randomised study investigating the physical and psychological experience of intermittent catheterization in adult individuals following spinal cord injury (SCI).
- Detailed Description
Given that intermittent catheterization is the recommended method of bladder management in individuals with SCI, it is crucial that the potentially negative cardiovascular and psychological responses to this procedure are examined. Individuals will undergo self-catheterization, then two standard of care catheterization procedures performed by an experienced urology nurse, while either blinded to or aware of time of catheterization. Continuous cardiovascular monitoring will be in place throughout all three procedures. Assessment of anxiety will be administered pre- and post- each procedure.

- Primary Outcome Measures
Name Time Method Change in state anxiety in the context of catheterization performed by urology nurse, participant aware of time of procedure (STAIS-5) 5 minutes before and 5 minutes after catheterization performed by urology nurse, participant aware of time of procedure The STAIS-5 will be used to measure participants' state anxiety prior to and after catheterization procedure performed by an experienced urology nurse, while the participant is aware of time of procedure. Sum score of the STAIS-5 will be calculated, which ranges between 5 to 20, with higher score indicating greater state anxiety.
BP during catheterization performed by urology nurse, participant aware of time of procedure During catheterization performed by urology nurse, participant aware of time of procedure Systolic and diastolic BP (mmHg) will be measured 5 minutes prior to and then throughout the standard of care catheterization performed by an experienced urology nurse, while the participant is aware of time of procedure.
Change in state anxiety in the context of catheterization performed by urology nurse, participant blinded to time of procedure (STAIS-5) 5 minutes before and 5 minutes after catheterization performed by urology nurse, participant blinded to time of procedure The STAIS-5 will be used to measure participants' state anxiety prior to and after catheterization procedure performed by an experienced urology nurse, while the participant is blinded to time of procedure. Sum score of the STAIS-5 will be calculated, which ranges between 5 to 20, with higher score indicating greater state anxiety.
BP during catheterization performed by urology nurse, participant blinded to time of procedure During catheterization performed by urology nurse, participant blinded to time of procedure Systolic and diastolic BP (mmHg) will be measured 5 minutes prior to and then throughout the standard of care catheterization performed by an experienced urology nurse, while the participant is blinded to time of procedure.
Blood pressure (BP) during self-catheterization During self-catheterization Systolic and diastolic BP (mmHg) will be measured continuously (beat-by-beat) via finger photoplethysmography, corrected to brachial pressure. BP will be measured 5 minutes prior to and then throughout the self-catheterization procedure.
Heart rate (HR) during self-catheterization During self-catheterization HR (BPM) will be recorded continuously via one-lead electrocardiogram. HR will be measured 5 minutes prior to and then throughout the self-catheterization procedure.
HR during catheterization performed by urology nurse, participant blinded to time of procedure During catheterization performed by urology nurse, participant blinded to time of procedure HR (BPM) will be measured 5 minutes prior to and then throughout the standard of care catheterization performed by an experienced urology nurse, while the participant is blinded to time of procedure.
Change in state anxiety in the context of self-catheterization (STAIS-5) 5 minutes before and 5 minutes after self-catheterization The State-Trait Anxiety Inventory - State, 5 item version (STAIS-5) will be used to measure participants' state anxiety prior to and after self-catheterization. Sum score of the STAIS-5 will be calculated, which ranges between 5 to 20, with higher score indicating greater state anxiety.
HR during catheterization performed by urology nurse, participant aware of time of procedure During catheterization performed by urology nurse, participant aware of time of procedure HR (BPM) will be measured 5 minutes prior to and then throughout the standard of care catheterization performed by an experienced urology nurse, while the participant is aware of time of procedure.
- Secondary Outcome Measures
Name Time Method Baseline trait anxiety During screening The 7-item General Anxiety Disorder (GAD) scale will be used to measure participants' anxiety. The GAD-7 sum score will be calculated, ranging from 0 to 21, with higher score indicating more severe anxiety symptoms.
Change in state anxiety in the context of self-catheterization (GA-VAS) 5 minutes before and 5 minutes after self-catheterization The Global Anxiety-Visual Analogue Scale (GA-VAS) will be used to measure participants' state anxiety prior to and after self-catheterization. Rating can range between 0 to 10, with higher rating on the GA-VAS indicates greater state anxiety.
Change in state anxiety in the context of catheterization performed by urology nurse, participant blinded to time of procedure (GA-VAS) 5 minutes before and 5 minutes after catheterization performed by urology nurse, participant blinded to time of procedure The GA-VAS will be used to measure participants' state anxiety prior to and after catheterization procedure performed by an experienced urology nurse, while the participant is blinded to time of procedure. Rating can range between 0 to 10, higher rating on the GA-VAS indicates greater state anxiety.
