NCT04772755

Brief Summary

This study was a prospective, randomized clinical trial that was conducted in adolescents (10 through 14 years of age) receiving at least one recommended intramuscularly administered vaccine to evaluate the efficacy and acceptability of using two different, simultaneously administered interventions that might prevent post-vaccination presyncope, and by extension syncope. The two interventions evaluated together were Buzzy®, which is a medical device designed to reduce vaccination pain, and an electronic game. The investigators evaluated both interventions when administered simultaneously (Buzzy® and electronic game). The investigators enrolled approximately 340 subjects into this study. Eligible adolescents were randomized (1:1) to either the intervention or control group: 1) intervention (Buzzy® and electronic game); or 2) control (usual care) to assess for acceptability and efficacy. Detailed data were collected and described from study participants including demographics, medical history, baseline generalized and state anxiety, and needle phobia. Participants were observed for 20 minutes following receipt of vaccines and reassessed for post-vaccination state anxiety, immediate and subsequent post-vaccination pain (within 1 minute and at 10 minutes), and the occurrence of witnessed syncope or presyncope, and presyncopal symptoms as rated by the modified Blood Donation Reactions Inventory (BDRI). Participants were asked to assess their acceptability of the intervention.

Outcome Measures

Primary Outcomes (1)

  • Number of Adolescents With Presyncope or Syncope After Vaccination in the Intervention and Usual Care Groups.

    Subjects were asked to complete a presyncope symptoms assessment (Modified BDRI: Blood Donations Reactions Inventory) at 20 minutes post vaccination. The number of adolescents with presyncope or syncope as determined by the modified BRDR or witnessed presyncope or syncope.

    Day 1, 20 minutes post vaccination

Secondary Outcomes (12)

  • Categorical Change (Increase, Decrease, no Change) in Pre- and Post- Vaccination State Anxiety.

    Day1: Pre-vaccination (baseline), Post-vaccination (20 minutes)

  • Numeric Change (Mean and Range) in Pre- Minus Post- Vaccination State Anxiety.

    Day1: Pre-vaccination (baseline), Post-vaccination (20 minutes)

  • Mean Injection-site Pain Scores on the Wong-Baker Faces Pain Scale© at ≤ 1 Minute Following Vaccination.

    Day 1, ≤ 1 minute after vaccination

  • Number of Adolescents Reporting an Injection Site Pain Score ≥ 2, on the Wong-Baker Faces Pain Scale©, ≤ 1 Minute Following Vaccination.

    Day 1, ≤ 1 minute following vaccination

  • Number of Adolescents Reporting an Injection Site Pain Score ≥ 4, on the Wong-Baker Faces Pain Scale©, ≤ 1 Minute Following Vaccination.

    Day 1, ≤ 1 minute following vaccination

  • +7 more secondary outcomes

Study Arms (2)

Usual Care

NO INTERVENTION

Participants received usual care that followed administration of a vaccine and a 20 minute post vaccination observation period.

Buzzy ® and Electronic Game

EXPERIMENTAL

Buzzy® was applied to the arm receiving vaccination for 30-60 seconds prior to vaccination and removed following vaccination. For the electronic game, participants were instructed to select a game from a prepopulated list of games on a tablet provided by the study team and then played that game for a specified amount of time before, during and after the vaccination administration.

Device: Buzzy® and Electronic Game

Interventions

Buzzy® was applied according to manufacturers directions and an electronic game was played. The participant was observed for 20 minutes post vaccination.
