Increased utilization of total joint arthroplasty after Medicaid expansion.
This study examined prior analyses that greater utilization of total hip arthroplasty (THA) and total knee arthroplasty (TKA) was to be expected after Medicaid expansion in 2014. Using 2012-2015 data from the HCUP Database, 9 expansion states (Arkansas, Arizona, Colorado, Iowa, Massachusetts, Maryland, Nevada, New York, and Vermont) were compared to 2 states that did not expand Medicaid (Florida and Missouri). After adjusting for community characteristics, THA and TKA increased 15% in 2014 and 23% in 2015 within expansion states compared to 2013. In non-expansion states, compared to 2013, there were significant decreases of 18% in 2014 and 11% in 2015.

Two-state comparison of total joint arthroplasty utilization following Medicaid expansion.
The aim of this study was to determine whether Medicaid expansion was associated with increased utilization rates of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Illinois (which expanded Medicaid) relative to Missouri (which did not expand Medicaid). The investigators concluded that their study demonstrated that Medicaid expansion in Illinois was associated with increased utilization of THA and TKA. They suggested that further study is needed to understand the impact of Medicaid expansion in other states and for other procedures.

Risk of subsequent joint arthroplasty in contralateral or different joint after index shoulder, hip, or knee arthroplasty: association with index joint, demographics, and patient-specific factors.
The purpose of this study using HCUP data was to determine how demographic and other patient-specific factors are associated with the risk of subsequent joint replacement in the contralateral or a different joint following an index joint replacement for osteoarthritis. Results showed a relatively high risk of subsequent replacement of the contralateral joint and a relatively low risk of subsequent replacement of a different joint within 5 to 8 years after an index total hip arthroplasty, total knee arthroplasty, or total shoulder arthroplasty. Obesity was associated with a higher risk of subsequent replacement of the contralateral joint or a different joint.

Prevalence of preoperative opioid use and characteristics associated with opioid use among patients presenting for surgery.
Researchers assessed the prevalence of preoperative opioid use and the characteristics of patients in a broadly representative surgical cohort. They found that patients undergoing lower extremity procedures were most likely to report preoperative opioid use, with 1 in 4 of all patients presenting for surgery reporting such use. They concluded that the data provided important insights into this population and would appear to help guide future preoperative optimization and perioperative opioid-weaning interventions.
