A summary of the article is shown below:

BACKGROUND: Health disparities exist among many patient populations, with race, payer status, hospital size and access to teaching versus non-teaching hospitals potentially affecting whether certain patients have access to the benefits of total wrist arthroplasty (TWA).METHODS: The National Inpatient Sample Database (NIS) was queried from 2001 to 2013 for TWA using the ICD-9 code 81.73. Patient-level data included age, sex, race, payer status, and year of discharge. Hospital-level data included hospital bed size, location, teaching status, and region.RESULTS: There were 1,213 patients identified who underwent TWA between 2001 and 2013. Total number of procedures decreased from 88 TWAs in 2001 to 65 in 2013. The yearly volume ranged from 33 in 2005 to 128 in 2007. The male-female ratio was 2.5 to 1. The majority of TWA procedures were performed at urban teaching hospitals (60.8%).CONCLUSIONS: The NIS database shows a downward trend of total wrist arthroplasty utilization. The majority of total wrist arthroplasties were performed at urban teaching hospitals indicating treatment occurs most often at academic centers of excellence.
