Abstract

Background: Patients with lymphoedema experience lifelong swelling and recurrent cellulitis despite use of complete decongestive therapy. Pneumatic compression devices (PCDs), including nonprogrammable and programmable devices that meet individual patient needs, support long-term self-care in the home. Objectives: Patients with either a nonprogrammable device (NP-PCD) or a dynamic pressure programmable device [P-PCD; Flexitouch ® (Tactile Medical, Minneapolis, MN, U.S.A.)] were evaluated to compare associated clinical and health utilization outcomes pre-/postdevice acquisition. Methods: Retrospective analysis of deidentified administrative claims from 2007 through 2013 of a large U.S. insurer. Outcome variables included rates of lymphoedema-related cellulitis, manual therapy use, outpatient services and inpatient hospitalizations. Multivariate regression analysis was performed to (i) compare outcomes for the 12 months pre- and postdevice acquisition and (ii) compare these two device types for their treatment-associated benefits. Results: The sample consisted of 1013 NP-PCD and 718 P-PCD recipients. Compared with the NP-PCD group, P-PCD patients’ baseline cellulitis rate was higher, whereas their postdevice cellulitis rate was lower. In the cancer cohort, the NP-PCD group had a 53% reduction in episodes of cellulitis (from 17·9% to 8·5%), compared with a greater 79% reduction in the P-PCD group (from 23·7% to 5·0%) (P < 0·001). In the noncancer cohort, the P-PCD group also experienced a larger 76% decline (from 31·0% to 7·4%) vs. 54% decline (from 22·9% to 10·6%) in cellulitis rates (P = 0·003). Outpatient service use reduced in both device groups, with greater reductions observed in the P-PCD group. Both device groups experienced reductions in manual therapy use. Inpatient hospitalizations were largely stable with reductions observed only in the noncancer cohort of the P-PCD group. Conclusions: P-PCD receipt was associated with superior lymphoedema-related health outcomes and reductions in cellulitis.
