Influencing Vaccinations: A Buzzy Approach to Ease the Discomfort of a Needle Stick-a Prospective, Randomized Controlled Trial.

BACKGROUND

The rate of annual influenza immunization in both the general public and health care workers is less than desirable. Mechanisms to improve compliance with recommendations are needed; prevention of immunization site pain has been suggested as a viable route because fear of pain and needles has been cited as a barrier.

AIMS

This study aimed to evaluate the impact of thermomechanical stimulation (Buzzy) on postprocedure pain ratings during vaccination in adults.

DESIGN

This was a randomized controlled trial of Buzzy during immunization.

SETTINGS

Three hospitals and two community health centers which are part of a large, integrated health system.

PARTICIPANTS/SUBJECTS: Employees presenting to employer-sponsored annual influenza vaccination clinics.

METHODS

A 10-cm visual analog scale was used to rate preinjection anxiety and expectation of pain as well as postprocedure pain scores; participants also rated their satisfaction with the vaccine injection on a 10-point Likert scale.

RESULTS

In total, 497 employee volunteers were recruited to participate. Preprocedure anxiety was similar between the experimental and control groups (1.53 vs. 1.48, p = .82), whereas self-reported postprocedure pain scores were significantly lower in the group that received the Buzzy during injection (0.87 vs. 1.12, p = .035). Mean satisfaction scores did not vary between the intervention and control groups (9.11 vs. 9.09, p = .87); however, more participants rated their experience as better than previous vaccination experiences in the Buzzy group than control (62.0% vs. 23.9%, p < .0001).

CONCLUSIONS

These results suggest that Buzzy reduced pain experienced by adults undergoing annual influenza vaccination and may improve overall experience. Buzzy can be used in adult patients to reduce pain during immunization and is especially effective in those with high levels of anxiety.
