Background: Lymphedema is a debilitating condition with high morbidity, yet despite advances in management, diagnostic ambiguity and fragmented referral patterns continue to delay appropriate care. We evaluated predictors of accurate diagnosis, microsurgical reconstruction candidacy, and secondary referrals generated during consultation with a lymphatic microsurgeon to highlight the need for a coordinated model of care. Methods: A retrospective chart review was performed for all outpatient referrals for ‘lymphedema’ from September 2020 to September 2021. Patient demographics, diagnostics, referral patterns, and lymphedema-related clinical data were collected. Results: 94 patients were referred for evaluation of possible lymphedema; lymphoscintigraphy confirmed diagnosis in 69. Following consultation, 23 patients received referrals for physical therapy, 17 for vascular surgery, and 8 for bariatric surgery or medical weight loss. Patients without lymphedema were more often referred to vascular surgery than those with lymphedema. Non-surgical candidates were more frequently referred to therapy or weight loss. Conclusions: Incorporating microsurgical reconstructive expertise into the evaluation of limb swelling improves diagnostic accuracy and refers patients- regardless of lymphedema status or surgical candidacy- to appropriate specialists. We propose a pathfinder model for patient flow that streamlines triage, improves access to accurate diagnosis and treatment, and prevents overburdening microsurgical practices with non-surgical patients.
