Clinical evidence

ImpediMed’s bioimpedance spectroscopy (BIS) devices have been studied and clinically validated in the areas of lymphedema, heart failure, body composition and veterinary BIS research.

Longitudinal and Transversal Bioimpedance Measurements in Addition to Diagnosis of Heart Failure

This preliminary study suggests that in HF longitudinal bioimpedance measurement in leg segment provides additional information to clinical examination and could even reflect sub-clinical hyper-hydration.

Monitoring of body fluid in patients with chronic heart failure using Bioimpedance-Spectroscopy

BIS offers a good possibility to monitor the water content of a person. This can be used in monitoring decompensated CHF patients. Since most patients with acute heart failure suffer not only from lung edema, but also from edema in limbs a combination of segmental and whole body BIS measurements offers the best options to supervise the course of diseases. In this paper, both BIS measurements show a strong correlation with the water balance and weight loss.

Incidence, treatment costs, and complications of lymphedema after breast cancer among women of working age: a 2-Year follow-up study.

Claims study of 1,877 patients for 2 years after the start of cancer treatment. 10% of patients developed lymphedema with ALND and chemotherapy associated with development. Higher medical costs associated with BCRL diagnosis ($23, 167 vs. $14,877) with higher rates of cellulitis/lymphangitis noted.
Although the use of claims data may underestimate the true incidence of lymphedema, women with BCRL had a greater risk of infections and incurred higher medical costs. The substantial costs documented here suggest that further efforts should be made to elucidate reduction and prevention strategies for BCRL.
