Recommended Action

Customers were asked to take the following actions: We recommend that you confirm the risk profile of your bilateral arm patients in MySOZO and take the following actions: - For patients at unilateral risk for lymphedema (over 90% of breast cancer patients), confirm that the unilateral arm L-Dex assessment is selected in the patient profile and continue to screen for early signs of lymphedema. - For patients at bilateral risk for lymphedema (3-10% of breast cancer patients), guidelines suggest routine screening using clinical exam and symptom assessment. - Complete and return the response form via link: https://forms.office.com/r/kafiuDbw21 In September, the firm will be issuing a SOZO software update to make unilateral L-Dex the sole assessment option for arms.
