Abstract

As the physician inventor and manufacturer of the Buzzy device I read with interest the article by Dr LimaOliveira et al “Quality Impact on Diagnostic Blood Specimen Collection Using a New Device to Relieve Venipuncture Pain” A coauthor and statistician also evaluated the results and methodology We have concerns both with the methodology analysis and discussion of the findings presentedThe article describes that Buzzy is applied proximal to the puncture site for 1 min before venipuncture and “continued until the end of the same procedure already done in the left forearm” It is not clear whether Buzzy was applied first for 1 min then blood was drawn in the opposite side then subsequently blood was drawn but total Buzzy application time would be between 90 and 180 s While the article does not mention that Buzzy was applied with a tourniquet photographs show that Buzzy was applied with the tourniquet strap included in the package One photo shows the black strapDr Baxter invented Buzzy and is the CEO of MMJ Labs the manufacturer of Buzzy® This conflict of interest was disclosed to participants in the informed consent of all studies Dr Baxter was not present for data collection Analysis was performed by Dr Lawson who has no financial conflict of interest to disclose Dr Lawson has previously collaborated with Dr Baxter as work for hire and as a colleague
