Assessing the Efficacy of Certificate of Need Laws Through Total Joint Arthroplasty.

Lawmakers suggest Certificate of Need (CON) laws' main goals are increasing access to healthcare, increasing quality of healthcare, and decreasing healthcare costs. This retrospective database study aims to evaluate the effectiveness of CON through analysis of total knee, hip, and shoulder arthroplasty (TKA, THA, and TSA, respectively). A review was performed using the Humana Insurance PearlDiver national database from 2007 to 2015. Access to care was approximated by the rates of total joint arthroplasty (TJA) in patients diagnosed with arthritis to the corresponding joint. The quality of care was assessed using complication rates after TJA. The total cost of TJA was approximated from average reimbursement to the healthcare facility per procedure. Patients in states without CON programs received TKA, THA, and TSA more frequently (p < .0001, p = .250, p = .019). No significant difference was found in studied complication rates between CON and non-CON states. Similarly, there was no trend found when comparing the cost of each procedure in CON versus non-CON states. These findings are consistent with other recent studies detailing the impact of CON regulation on THA and TKA. The apparent nonsuperiority of CON states in achieving their purported goals may call into question the effectiveness of additional bureaucracy and regulation, suggesting a need for further examination.
