Why Expanding Access to a Lymphedema Prevention Program is Needed for Cancer Patients
91% of patients believe cancer care teams should offer patients a Lymphedema Prevention Program
- Optimize workflows and patient outcomes
- Track utilization of L-Dex on your SOZO devices
- Understand your L-Dex patient population
Designed for Lymphedema
- The L‑Dex score, only available from ImpediMed, is designed to detect small lymphedema-related fluid changes in the limbs.
- L‑Dex compares the fluid in a limb at-risk for lymphedema to a healthy limb in order to help detect lymphedema.
- FDA-cleared for unilateral and bilateral secondary lymphedema of the arms and legs, in women and men.
- L‑Dex is validated to detect lymphedema at its earliest, subclinical stage
- Detects fluid changes as small as 36 ml (2.4 tablespoons)1
- Validated against lymphoscintigraphy2
- 80% Sensitive and 90% Specific in detecting subclinical lymphedema following cancer surgery with a 6.5 change from a pre-treatment baseline3
- 92% of patients with early detection using L-Dex and intervention did not progress to chronic lymphedema4
- Significantly lower progression to chronic lymphedema with early detection using L-Dex and intervention versus using tape measure4
- L-Dex more precise and reliable than tape measure4
See the Latest Clinical Evidence
- 16 of the 31 members of the National Comprehensive Cancer Network® (NCCN®) use SOZO with L-Dex
- BIS is recommended in lymphedema clinical practice guidelines from the American Physical Therapy Association5, eviCore Healthcare6, and the National Lymphedema Network7
- Major institutions including University of Kansas, University of Pittsburgh Medical Center, Memorial Sloan Kettering, and MD Anderson have published their experience using L-Dex8-11
SOZO Digital Health Platform
SOZO uses ImpediMed’s BIS technology to measure and track critical information about the human body to aid clinicians in managing chronic disease and maximizing patient health. SOZO is non-invasive, fast, and easy to use. Results from the 30-second test are available immediately providing proactive patient care including early detection of disease progression, treatment monitoring, and patient education.
