Fear of getting a shot is a major concern that must be addressed in children to encourage clinic visits and promote immunization.

OBJECTIVES: This study aims to determine the effectiveness of ShotBlocker™ in reducing pain associated with intramuscular injection in preschool children.

STUDY DESIGN: Randomized controlled trial.

SETTING: Dalandanan Elementary School, Dalandanan, Valenzuela City.

METHODOLOGY: 119 kindergarten pupils were randomly allocated, 59 children with ShotBlocker™ and 60 children without ShotBlocker™. DPT injection was administered. Self-reporting of pain was done using the Wong – Baker FACES Pain Scale.

RESULTS: The baseline characteristics based on age (p = 0.784), height (p = 0.702) and weight (p =0.797) of those who were randomized to the ShotBlocker™ group were comparable with those who did not have the device. 93.2% of those with ShotBlocker™ experienced mild to no pain compared to 51.7% of those without ShotBlocker™. Regardless of the gender (male p < 0.001 and female p = 0.002) those with the device had significantly lower pain scores than those without the device (p < 0.010).

CONCLUSION: ShotBlocker™, a colorful plastic device with multiple contact points on its underside, significantly reduces pain associated with intramuscular injection. This may allay the fear of getting a shot.
