Aims: To assess the budget impact to a US commercial health plan of providing access to the Flexitouch (FLX) advanced pneumatic compression device (Tactile Medical) to lymphedema (LE) patients with either comorbid chronic venous insufficiency (CVI) or frequent infections.
Methods: Budget impact was calculated over 2 years for a hypothetical US payer with 10-million commercial members. Model inputs were derived from published sources and from a case-matched analysis of Blue Health Intelligence (BHI) claims data for the years 2012-2016. To calculate the budget impact, the Status Quo budget (i.e. total cost for LE and sequelae-related medical treatment) was compared to the budget under each of three Alternate Payer Policy scenarios which assumed that a sub-set of patients was redistributed from their initial treatment groups to a group that received FLX. Model outputs included cumulative payer costs, net budget impact, and breakeven point. Sensitivity analyses were performed to assess the impact of model inputs on results.
Results: Increasing access to FLX yielded a favorable budget impact in every scenario. For LE patients with comorbid CVI, the three alternate scenarios resulted in cumulative 2-year budget impacts of -$52,841, -$173,317, and -$375,601, respectively. For LE patients with comorbid frequent infections, the three alternate scenarios resulted in cumulative 2-year budget impacts of -$192,729, -$259,339, and -$613,179, respectively.
Limitations: Use of claims data assumes accurate coding and does not allow one to control for disease severity or treatment adherence. Also, the distribution of patients between treatment arms was determined using claims data from a specific payer organization, and could differ for health plans with different coverage policies.
Conclusions: While previous studies have illustrated cost savings with adoption of FLX, US commercial health plans may also achieve tangible cost savings by expanding access to FLX for LE patients with comorbid CVI and multiple infections.
