Study summary

Preprocedural, preoperative, and prevascular access anxiety in pediatric patients has been previously shown to increase the likelihood of family stressors, agitation, sleep disturbances, and negative behavioral changes. The purpose of this study is to determine if a non-invasive distracting device (Virtual Reality (VR) headset, Augmented Reality (AR) headset, or bed mounted Video Projection unit (i.e. BERT, Bedside EnterRtainment Theater)) is more effective than the standard of care (i.e., no technology based distraction) for preventing anxiety before non-invasive surgical sub-specialty procedures among children during out-patient clinic visits. Examples of the most common procedures include, but are not limited to gastrostomy tube exchanges, suture removals, dressing changes, foley insertions, EEG set up, chest tube removals, cast removals, pin removals and other similar procedures. (The investigators refer to these procedures under an umbrella term of non-invasive surgical subspecialty procedures). The anticipated primary outcome will be reduction of child's anxiety during and after procedures.

Read the detailed description

Anxiety among children undergoing non-invasive surgical subspecialty procedures is common. Not only is high anxiety traumatic, but research in a surgical setting indicates that high anxiety in children before surgery leads to adverse outcomes such as increased pain and analgesics requirements, delayed hospital discharge and maladaptive behavioral changes. Treating anxiety may decrease any of these undesirable behaviors that may arise when experiencing a non-invasive surgical subspecialty procedure in a clinical setting.

In this study, investigators hope to determine if technology based distractions (VR headsets with headphones, AR headset, or BERT projector) are more effective than standard care for preventing high anxiety before non-invasive surgical subspecialty procedures. As a secondary objective of the study, the investigators seek to determine if the use of technology based distraction will result in higher parent and patient satisfaction as well as evaluate which techniques are most effective. As a tertiary aim, the investigators seek to understand if passive or active interventions are more effective in decreasing anxiety.

What researchers measure

Primary outcomes

  1. Change in Pain Score

    Peak Pain Score minus Baseline Pain Score. Pain scores range from 0 to 10. 0 represents no pain and 10 represents the worst pain possible. Change in pain score ranges from +10 to -10. Higher positive values represent a worse outcome, and higher negative values represent a better outcome.

    Time frame: Immediately Post Non-Invasive Surgical Subspecialty Procedure Minus Baseline

Secondary outcomes

  1. Anxiety Score

    Fear Faces. Images of faces depicting increasing levels of fear measure the degree of fear the patient is experiencing. Faces correlate to a score ranging from 0 to 4. 0 represents the least scared and 4 represents the most scared. Higher values represent a worse outcome.

    Time frame: Immediately Post Non-Invasive Surgical Subspecialty Procedure Minus Baseline

  2. Anxiety Meter

    Childhood Anxiety Meter

    Time frame: Immediately Post Non-Invasive Surgical Subspecialty Procedure Minus Baseline

  3. Family Satisfaction

    Family Satisfaction Survey

    Time frame: Immediately Post Non-Invasive Surgical Subspecialty Procedure

  4. Patient Satisfaction

    Patient Satisfaction Survey

    Time frame: Immediately Post Non-Invasive Surgical Subspecialty Procedure

  5. Patient Cooperation

    Brief Behavioral Distress Scale (BBDS). Measures patient cooperation. Behavior cooperation choices exist on a scale consisting of non-interfering behaviors, potentially-interfering behaviors and interfering behaviors. Non-Interfering Behaviors = minor, verbal/vocal distress, moan, comfort seeking, etc. Potentially Interfering Behaviors = intense verbal/vocal distress, scream, shout, tensing of muscles, clench, flinch, gritting of teeth, etc.Interfering Behaviors = escape, disrupt, avoid, aggress, etc. Interfering behaviors represent a worse outcome.

    Time frame: At the time of Non-Invasive Surgical Subspecialty Procedure

  6. Patient Compliance

    Modified Induction Compliance Checklist

    Time frame: At the time of Non-Invasive Surgical Subspecialty Procedure

  7. Parent Pain Catastrophizing Scale (PCS-P)

    PCS-P. Measures the extent of thought concerning pain Scale ranges from 1 to 5. 1 represents not thinking at all about pain and 5 represents thinking very much about pain. Higher values represent a worse outcome.

    Time frame: Baseline and Immediately Post Non-Invasive Surgical Subspecialty Procedure

Ran from Oct 2017 to primary completion in Jun 2023, 68 months.

Of 457 non-industry interventional studies with no phase under Stress, Psychological, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 26. This study's 68 months is above that.

Counting every sponsor, half of 470 studies reached it within 13 months; a quarter within 5 and three quarters within 26.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 28, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
