Background: Vascular anomalies (VAs) are heterogeneous lesions. Symptoms vary widely by lesion type and complexity. VA patients often require life-long interdisciplinary care; however, there is a paucity of data on the healthcare utilization of VA patients, and their burden on the healthcare system remains largely unquantified. We hypothesize that healthcare utilization by complex lymphatic malformation (LM) and venous malformation (VM) patients will be significantly higher compared with simple LM and VM patients.
Methods: A retrospective, longitudinal study was performed of LM/VM patients seen through multidisciplinary VA clinics between January 1, 2019 and December 31, 2020. Data were collected from each patient's first presentation through December 31, 2021 and included number of office visits, imaging studies, specialists involved, procedures, hospitalization data, and approximate costs, normalized to per year utilization. Patients were divided into "simple" and "complex" LMs/VMs. Involvement of the airway, more than one anatomic area, and/or complex lymphatic anomalies were defined as "complex."
Results: In total, 28 simple and 29 complex LM patients and 51 simple and 18 complex VM patients were identified. Complex LM and VM patients had significantly higher numbers of imaging studies, specialists involved, procedures and hospitalizations, and costs incurred. Complex LM patients also had significantly higher per year office visits.
Conclusions: VA care is chronic and costly, especially for complex LM/VM patients. LM/VM complexity was a predictor for increased inpatient and outpatient healthcare utilization and higher costs. Better awareness of the healthcare utilization trends of LM/VM patients will allow for improved counseling for these patients regarding prognosis and expectations.
