Study Details

Study Description

Brief Summary

This is a prospective, randomised study investigating the physical and psychological experience of intermittent catherization in adult individuals following spinal cord injury (SCI).

Condition or Disease Intervention/Treatment Phase
  • Procedure: Self-catheterization
  • Procedure: Catheterization performed by urology nurse, participant blinded to time of procedure
  • Procedure: Catheterization performed by urology nurse, participant aware of time of procedure
N/A

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-catherization, then two standard of care catherization 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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Individuals with motor-complete SCI

Individuals with motor sensory complete injury (AIS A/B)

Procedure: Self-catheterization
Participants will perform self-catheterization, following the same routine for intermittent catheterization at home

Procedure: Catheterization performed by urology nurse, participant blinded to time of procedure
Participant will undergo procedure to completely empty bladder; Participant in supine position, and resting blood pressure and heart rate will be recorded for period of 5 minutes prior to catheterization; Perineum and genital areas will be draped and they will be not aware about exact timing of catherization Catherization will be conducted following standard clinic procedure by experience urology nurse.

Procedure: Catheterization performed by urology nurse, participant aware of time of procedure
Participant will undergo procedure to completely empty bladder; Participant in supine position, and resting BP and HR will be recorded for period of 5 minutes prior to catheterization; Perineum and genital areas will be visible to participant and they will be fully aware about exact timing of catherization Catherization will be conducted following standard clinic procedure by experience urology nurse.

Individuals with motor sensory incomplete injury (AIS C/D)

Procedure: Self-catheterization
Participants will perform self-catheterization, following the same routine for intermittent catheterization at home

Procedure: Catheterization performed by urology nurse, participant blinded to time of procedure
Participant will undergo procedure to completely empty bladder; Participant in supine position, and resting blood pressure and heart rate will be recorded for period of 5 minutes prior to catheterization; Perineum and genital areas will be draped and they will be not aware about exact timing of catherization Catherization will be conducted following standard clinic procedure by experience urology nurse.

Outcome Measures

Primary Outcome Measures

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. Change in state anxiety in the context of catheterization performed by urology nurse, participant aware of time of procedure (GA-VAS) [5 minutes before and 5 minutes aftercatheterization performed by urology nurse, participant aware of 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 aware of time of procedure. Higher rating on the GA-VAS indicates greater state anxiety.
