Background
Treatment of carpal tunnel syndrome (CTS) in commercially insured patients across the spectrum of provider types has rarely been described.
Objective
The purpose of this study was to describe patterns of types of treatment for patients with CTS using a large commercial insurance database.
Design
Retrospective cohort descriptive study
Setting
Administrative health data from the Clinformatics® Datamart (OptumInsight, Eden Prairie, MN).
Patients
Adults with a primary diagnosis of CTS seen from between January, 2010 to December, 2012 who had a total of 48 months of continuous data (12 months prior to diagnosis and 36 months after diagnosis) (n = 24,931).
Outcomes
Frequency of types of treatment (heat, manual therapy, positioning, steroid, stretching, surgery) by number of treatments, number of visits, provider type, and characteristics.
Results
Fifty-three percent of patients received no reported treatment and 50.4% had no additional visits. Surgery (42.5%) and positioning (39.8%) were the most frequent single treatments. Patients who were seen by orthopedist for their first visit more frequently received some treatment (75.1%) and at least one additional visit (74.1%) compared to those seen by general practitioners (59.5%, 57.5% respectively) or other providers (65.4%, 68.4 respectively). Orthopedists more frequently prescribed positioning devices (26.8%) and surgery (36.8%) than general practitioners (18.8%, 14.1%, respectively) or other providers (15.7%, 19.7%, respectively). Older adults more frequently had CTS surgery as did people who lived in the Midwest. Overall, only 24% of CTS patients had surgery.
Conclusions
For more than half of patients with CTS no treatment was provided after an initial visit. Surgery rates were much lower than what has previously been reported in the literature. Generally, patients with CTS receive treatments that are supported by current treatment guidelines.
