Reduction of Perioperative Anxiety Using a Hand-held Video Game Device

Overview

Distraction techniques, such as use of a virtual reality device, have been used to augment or replace pharmacological practices for relief of anxiety in pediatric patients prior to surgical procedures. This relief can not only benefit medical staff, as procedures may be easier to perform and require less time, but also have a calming effect on the the parent during the procedure if they feel that their child is being better cared for. In addition, decreased anxiety prior to surgical procedures have been shown to reduce maladaptive behaviors post-operatively. This prospective study plans to evaluate the anxiety level of parents and pediatric patients in an outpatient surgery center pre-, during and post-operatively with and without the use of a virtual reality distraction device. The goal is to determine the existence of correlations between distraction techniques (in this case, the use of handheld video games) pediatric patient anxiety, parental anxiety, and parental satisfaction with the experience surrounding the procedure.

General Data will be collected for patients being treated at Patewood Outpatient Surgery Center following legal guardian consent. Patients receiving surgical treatment involving the use of an anesthesia mask, age 4 to 10, will be included in the study. Exclusion criteria will include ear tube cases, patients physically incapable to play a video game, patients of non-English speaking caregivers, and patients without legal guardian present day of surgery. IV Ear tube cases are too short a procedure for data collection and at least one caretaker must be capable of taking both an oral and written survey. For the purposes of this study, a "caregiver" will be defined as an adult that spends a significant amount of time with the patient, and meets the following criteria. The primary caregiver is the adult that is responsible for the minor patients' care. The caregiver may reside with the patient full-time or part-time but have the information necessary to assess the child's behavior before and after the outpatient procedure. Data collected for each patient will include demographics, random placement in Video Game/No Video game group, surgical procedure, information normally recorded by surgeon or anesthesiologist including duration of surgery and duration under anesthesia, caregiver reported changes in patient behavior following surgery, and scores of the anxiety being felt by caregivers and patients. Anxiety scores will be determined using shortened versions of validated anxiety scoring assessments. Behavioral changes will be recorded using a shortened version of the Post Hospital Behavior Questionnaire (PHBQ). Assessments have been shortened to increase study participation, and eliminate any impact the study may have had on day-to-day operations at Patewood Outpatient Surgery Center. Caregivers will also be asked to fill out a hospital created survey related to how satisfied they are with the care of the patient. It will be referred to as the Preoperative Hospital Satisfaction Survey (PHSS). This survey will be administered while the surgical procedure is in progress, when the caregivers are sitting in the waiting room. The survey is to be a reflection of how caregivers perceive preoperative separation care given to patients, so will not be influenced by surgical outcome. Consent Legal guardians of patients are contacted over the phone by Patewood Outpatient Surgery Center registration per standard preoperative care procedure. Before concluding the normal preoperative interview, a script will be read that introduces the guardian to the study and its goals. The guardian will then be asked if they are interested in learning more about the study. Those who answer "no" will be removed from a list of potential participants. Those who answer "yes" or "maybe" will be given more information about study participation after arriving at the outpatient surgery center on the day of their scheduled appointment. A more thorough explanation of the study will be given and any questions answered. If a guardian is interested in participating, they will be provided a consent form to fill out. Group assignment Patients will be assigned into a "Video Game group" or a "No Video Game group." All patients on any particular day will be assigned into the same group. This is done to prevent one patient from feeling disappointed after seeing another patient with a video game, and then learning they may not have one. Group assignment will alternate each day. Assessment and Survey Descriptions Modified Yale Preoperative Scale (mYPAS)- Observational survey used to quickly score the anxiety level of children during preoperative holding and induction of anesthesia. It has frequent use and validation as an accurate tool for determining the anxiety level of pediatric surgical patients. Each section has 4 to 6 numbers listed, each corresponding with different patient description. For each section, the number by the most accurate patient description is circled. (Jenkins)(Kain) State Trait Anxiety Inventory (STAI)- Self-taken survey for adults. Gives 2 different scores. One score is an indicator of susceptibility to stressful situations, the other score is the level of anxiety felt while taking the survey. It has frequent use and validation as a tool for determining anxiety levels of adults. (Spielberger) Post Hospital Behavior Questionnaire (PHBQ)- Survey taken by primary caregiver of a patient after leaving the hospital. The survey is designed to identify maladaptive behaviors a patient has developed following a time at a hospital. Questions must be answered "much less than before", "less than before", "same as before", "more than before", or "much more than before". This survey is sensitive only to the change in frequency of behaviors, not their presence or absence. Therefore, undesirable behavior existing prior to a hospital stay should have no influence on the PHBQ score. All surveys used in this study were truncated. Any modification was evaluated and approved by the staff psychologist (PhD.) familiar with using surveys to research anxiety and stress of patients and their families. Any questions that were included or excluded from the surveys was done so under expert direction. Perioperative Holding After completing standard preoperative procedure, a nurse will complete a short observational survey (mYPAS \[modified Yale Preoperative Scale\] or mYPAS-SF) to score the patients current anxiety level. Just prior to separation from the caregiver, the patient will be given (or not given) a Video Game by the nurse. During separation, another mYPAS will be scored. Operating Room Another mYPAS will be scored during the induction of anesthesia. If the patient has a video game, the patient is allowed to play as long as he/she wants. Often times, this is up until the procedure begins. Caregivers During Procedure One or two primary caregivers will be asked to fill out a shortened STAI (State Trait Anxiety Inventory) and PHSS. Follow-up Phone Calls The day following surgery, standard postoperative care procedure will be followed. This includes a phone call to the caregiver of a patient. Before concluding the phone call, the instructions at the top of the shortened PHBQ will be read to the caregivers participating in the survey. Then each question will be read and answered. One week and 2 weeks following surgery, the caregiver will be called and the shortened PHBQ will be administered. Statistics The existence of correlations between maladaptive behavior, patient anxiety, caregiver susceptibility to anxiety, caregiver experience of anxiety, caregiver satisfaction, video game use, and any other collected data will be determined. All information from this study will be used to describe our cohort only. All data will be expressed in summary and is meant to contribute to the generalizable knowledge of the field.
