Detailed Description

Kidney Failure Requiring Replacement Therapy (KFRT) is a growing global health challenge. In 2023, the number of global cases of KFRT reached 4.59 million, affecting approximately 5 million people worldwide. Regionally, the burden is significant, with 230,000 cases reported in North Africa and the Middle East, and specifically 8,800 cases in Iraq.

Hemodialysis remains the primary life-sustaining treatment for these patients. To perform hemodialysis efficiently, a reliable vascular access is required, with the arteriovenous fistula (AVF) being the gold standard. However, the procedure requires the insertion of large-gauge needles into the fistula repeatedly (usually three times a week), which is often associated with significant pain and distress.

Needle phobia, anticipatory anxiety, and procedure-related pain are common challenges among hemodialysis patients. Unmanaged pain and anxiety can lead to poor adherence to treatment, adverse physiological responses (such as hypertension and tachycardia), and a reduced quality of life.

Virtual Reality (VR) is an immersive technology that draws the patient's attention away from the noxious stimulus by creating a simulated environment. The study aims to evaluate the efficacy of VR as a distraction method to reduce pain and anxiety during AVF cannulation in hemodialysis patients compared to standard care.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • Patients using a functioning arteriovenous fistula (AVF).
  • Conscious, oriented, and able to communicate.
  • Normal or corrected vision and hearing suitable for VR use.
  • Patients capable of giving written informed consent.

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Virtual Reality Group
Participants in this group will receive distraction therapy using Virtual Reality (VR) glasses during the AVF insertion. The VR session starts 2 minutes before the procedure and continues for 3 minutes during the insertion. Utilizing the Solomon Four-Group Design, this group is randomly subdivided into two subgroups: in Subgroup A, anxiety is assessed before the intervention, while in Subgroup B, no pre-test assessment is performed. Both subgroups undergo post-test measurement for pain and anxiety immediately after the procedure.
Device: Virtual Reality
The intervention involves using VR glasses to provide audiovisual distraction. Participants will watch a 360-degree underwater video with calming music. The VR session starts 2 minutes before the procedure and continues for 3 minutes during the insertion
Active Comparator: Control Group
Participants in this group will receive standard routine nursing care for AVF insertion without any additional distraction techniques. Utilizing the Solomon Four-Group Design, this group is randomly subdivided into two subgroups: in Subgroup C, anxiety is assessed before the procedure, while in Subgroup D, no pre-test assessment is performed. Both subgroups undergo post-test measurement for pain and anxiety immediately after the procedure
Other: standard of care
Routine nursing care for AVF insertion, including skin disinfection and needle insertion according to the hospital's standard protocols, without any additional distraction techniques.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
pain intensity
Time Frame: Immediately after the needle insertion procedure
Pain intensity will be assessed using the Visual Analog Scale (VAS). This scale consists of a 10-cm horizontal line where 0 represents "no pain" and 10 represents "worst possible pain." Participants will mark their perceived pain level on the line immediately after the needle insertion and removal of the VR glasses.
Immediately after the needle insertion procedure
Anxiety Level
Time Frame: Immediately after the needle insertion procedure
The anxiety level will be assessed using the Visual Analog Scale (VAS) for Anxiety. This scale consists of a 10-cm horizontal line, where 0 indicates "no anxiety" and 10 indicates "worst possible anxiety." Participants will be asked to place a mark on the line corresponding to their perceived anxiety level immediately after the needle insertion and removal of the VR glasses.
