Effect of VR on Pain, Fear and Anxiety During Accessing a Port With Huber Needle in Pediatric Cancer Patients
Condition: Pain; Fear; Anxiety State
MeSH terms: Anxiety Disorders
Study type: Interventional

Summary: 
      Virtual Reality (VR) can be used during needle-related procedures in children with cancer.
      The aim of this study was to investigate the effect of VR during access the venous port with
      Huber needle-related pain, fear and anxiety of children and adolescents with cancer.
    

Detailed description: 
      Study hypotheses H1: The venous port access-related pain, fear and anxiety scores of patients
      in VR group during access the venous port with Huber needle is lower from the control group.

      Methods Study Design and Sample This is a randomized controlled study of virtual reality
      during access the venous port with Huber needle performed in a pediatric hematology and
      oncology setting at two university hospital in Izmir. Data were recorded on 42 children and
      adolescents with cancer aged 6-17 undergoing Huber needle insertion into a subcutaneously
      implanted intravenous port.

      Gpower 3.1.0 statistical program showed that 21 patients in each group were needed based on
      an effect size of 0.20, at a power of 0.80, and an acceptable type I error size of 0.05.

      Randomization Forty-two children enrolled the study. They were allocated by the blocked
      randomization; gender, age (6-12/13-18), subcutaneously implanted intravenous port insertion
      time (≤1month/>1month). Randomization was performed with a computerized random-number
      generator. Forty-six children were assessed for eligibility; 4 children were excluded;
      refused to participate (n = 2); had visual problem (n = 1); did not want to wear VR glasses
      to see access the venous port with Huber needle before the procedure (n = 1).

      Instruments Demographic Form. This form included the child's gender, age, the last blood draw
      time, blood draw success and also the parent demographics such as age, educational level.

      Wong-Baker FACES (WBS) Pain Rating Scale. This scale uses in children aged 3 and older to
      rate pain severity, ranges from 0 (very happy/no pain) to 10 (hurts worst).

      The Child Fear Scale (CFS). This one-item scale measures procedure-related fear in children,
      consists of five sex-neutral faces, ranges from 0 (no fear) to extreme fear (4).

      The Children's Anxiety Meter (CAM-S). The CAM-S assesses children's anxiety and uses before
      medical procedures. The CAM is drawn like a thermometer with a bulb at the bottom and also
      includes horizontal lines at intervals going up to the top (0-10).

      Procedure The researcher informed the children and their parents about the aim of the study.
      Children and adolescents with cancer were randomized to either VR or control group. All
      children underwent standard care in this access the venous port with Huber needle procedure.
      In standard care: children/adolescents and their parents were informed by the staff at least
      one hour before the procedure. None pharmacological methods were used in standard care at the
      accessing the venous port with Huber needle in the units.

      CFS and CAM-S were administered by the researcher to the children/adolescent and his/her
      parent to assess child's fear and anxiety levels about the port needle insertion 5 minutes
      ago before the procedure. Children/adolescent and his/her parent were blinded to each other
      score. Parents of children or adolescents were also present during the procedure. All
      accessing the venous port with Huber needle procedure was performed in patient's room.

      Virtual Reality intervention In the VR Group, after the CFS and CAM-S were administered, VR
      applications introduced to the child or adolescent by the researcher before the procedure.
      When the child is ready for the procedure, the researcher started the application by wearing
      virtual glasses to the child/adolescent. VR intervention was started 2-3 min before the
      procedure and continued until the procedure was completed.

      Ethics Ethical approval was received from the Non-Invasive Clinical Studies Ethics Committee
      of University where the research was conducted (3481GOA 2017/20-01). The researcher informed
      about the aim of the study and obtained written consent forms from children and parents.
