Cost Analysis and National Trends in the Treatment of Dupuytren Contracture Comparing Collagenase Injection, Needle Fasciotomy, and Open Fasciectomy Procedures.

Background: Dupuytren contracture (DC) is a common disorder characterized by progressive fibrosis of palmar fascia. This study analyzed cost trends of 3 common treatments for DC: fasciotomy, fasciectomy, and collagenase injection (CI)/cord manipulation.

Methods: The Vizient Clinical Data/Resource Manager electronic database was reviewed for all procedures for the treatment of DC at participating hospitals in the United States (US) from October 1, 2015, to September 1, 2019. Cases were placed into 1 of 3 categories: (1) CI, (2) needle fasciotomy (NF), and (3) open fasciectomy (OF). Total and direct costs were averaged for each procedure and compared nationally and regionally. Temporal trends and specific market share were analyzed. One-tailed t test and Pearson correlation analysis was performed (P < 0.05 and r > 0.9 or r < -0.9 was considered significant).

Results: A total of 22,974 total cases were identified. A total of 16,966 OF, 3962 NF, and 2046 CI were performed. There was a nearly a 4-fold increase in number of procedures to treat DC from 2015 to 2018. Market share percentage of each procedure stayed relatively similar over time. However, market share percentage differed between procedures. Needle fasciotomy had the lowest market share percentage approximately 7%. Collagenase injection had the highest average cost at US $4453.66 and was significantly higher than OF at US $3394.90 and NF at US $2010.75. Cost and distribution of procedures were further analyzed by geographic regions. In 2018, 32% of procedures performed were in the Northeastern US, 29% in the Midwestern US, 23% in the Southern US, and 16% in the Western US. Total number of Dupuytren procedures increased more than 300% in all regions across the US from 2015 to 2018. In every region, NF was the lowest cost intervention. Cost of OF and CI varied between regions and was often the most expensive intervention.

Conclusions: Treatment of DCs with NF seems to be the least costly treatment option. Needle fasciotomy seems to be the least commonly performed procedure. Regional data show variations in the cost of OF and CI. However, OF has the majority market share nationally and regionally. Although the cost of these procedures seems to vary regionally, the type of procedures being performed seem to be similar across regions.
