Comparing the benefits of applying a vacuum assisted lancing device in reducing lancing pain, improving self-monitoring frequency and reducing HbA1c in people with diabetes

Abstract

Background and aims: For most people with diabetes (PwD), lancing fingertips for obtaining a blood sample is unavoidable during blood glucose monitoring (BGM). This study investigated the potential benefits of applying a vacuum over the penetration site immediately, before, during, and after lancing to determine if a vacuum would allow a less painful lancing process from fingertips and alternate sites, while still drawing sufficient blood, thereby allowing PwD to have a painless lancing experience and improving self-monitoring frequency. The cohort was encouraged to use a commercially available vacuum assisted lancing device. Change in pain perception, testing frequency, HbA1c, and future probability of VALD use were determined.

Methods: In a 24-week randomized open-label, interventional, cross-over trial, 110 PwD were recruited who used VALD and non-vacuum conventional lancing devices, for 12 weeks each. Percentage reduction in HbA1c, percentage BGM adherence, scores of pain perception, and probability of selecting VALD in the future were measured and compared.

Results: There was reduction in overall HbA1c values (mean ± SD), (from 9.01 ± 1.68% at baseline to 8.28 ± 1.66%) and individually in T1D (from 8.94 ± 1.77% to 8.25 ± 1.67%) and T2D (from 8.31 ± 1.17% to 8.59 ± 1.30) after using VALD for 12 weeks. Lower pain perception and high probability of using VALD over conventional devices were observed.

Conclusion: The study highlights the benefits of applying a vacuum to the lance site which enhances the effectiveness in reducing and eliminating pain, improving self-monitoring frequency, and lowering HbA1c over non-vacuum conventional devices.
