摘要

BACKGROUND The recent federal ruling to against Affordable Care Act(ACA),specifically the mandate requiring people to buy insurance,has once again brought the healthcare reform debate to the spotlight.The ACA increased the number of insured Americans through the development of subsidized healthcare plans and health insurance exchanges.Insurance-based differences in the rate of upper extremity elective orthopaedic surgery have been described before and after healthcare reform in Massachusetts,where a similar mandate was put into place years before the ACA was passed.However,no comprehensive study has evaluated insurance-based differences of knee elective surgery before and after reform.AIM To investigate how an individual mandate to purchase health insurance affects rates of knee surgery.METHODS A retrospective review was performed within an orthopaedic surgery department at a tertiary-care,academic medical center in Massachusetts.The rate of elective knee surgery performed before and after the healthcare reform(2005-2006 and 2007-2010,respectively)was calculated.The patients were categorized by insurance type(Commonwealth Care,Medicare,Medicaid,private insurance,Workers’Compensation,TriCare,and Uninsured).Usingχ^2 testing,differences in rates of surgery between the pre-reform and post-reform period and among insurance subgroups were calculated.RESULTS Rate of surgery increased in the post-reform period(pre-reform 8.07%(95%CI:7.03%-9.11%),post-reform 9.38%(95%CI:8.74%-10.03%)(P=0.04)and was statistically significant.When the insurance groups and insurance types were compared,the rates of surgery are not significantly different before or after reform.CONCLUSION The increase in the rate of elective knee surgery in the post-reform period suggests that health care reform in Massachusetts has been successful in decreasing the uninsured population and may increase health care expenditures.This is a hypothesis generating study that suggests further avenues of study on how mandated coverage may change healthcare utiliz
