This dissertation evaluates three current policy ideas: (1) global payment within an accountable care contracting model, (2) physician fee cuts, and (3) expanding the role of competitive bidding in Medicare.;Chapter one studies the effect of global payment and pay-for-performance on health care spending and quality in accountable care organizations. I evaluate the Blue Cross Blue Shield of Massachusetts Alternative Quality Contract (AQC), which was implemented in 2009 with seven provider organizations comprising 380,000 enrollees. Using claims and quality data in a quasi-experimental difference-in-differences design, I find that the AQC was associated with a 1.9 percent reduction in medical spending and modest improvements in quality of chronic care management and pediatric care in year one.;Chapter two studies Medicare's elimination of payments for consultations in the 2010 Medicare Physician Fee Schedule. This targeted fee cut (largely to specialists) was accompanied by a fee increase for office visits (billed more often by primary care physicians). Using claims data for 2.2 million Medicare beneficiaries, I test for discontinuities in spending, volume, and coding of outpatient physician encounters with an interrupted time series design. I find that spending on physician encounters increased 6 percent after the policy, largely due to a coding effect and higher office visit fees. Slightly more than half of the increase was accounted for by primary care physician visits, with the rest by specialist visits.;Chapter three examines competitive bidding, which is at the center of several proposals to reform Medicare into a premium support program. In competitive bidding, private plans submit prices (bids) they are willing to accept to insure a Medicare beneficiary. In perfect competition, plans bid costs and thus bids are insensitive to the benchmark. Under imperfect competition, bids may move with the benchmark. I study the effect of benchmark changes on plan bids using Medicare Advantage data in a longitudinal market-level model. I find that a... | Keywords/Search Tags: | Care, Competitive bidding, Spending, Organizations, Reform, Payment, Bids | | Related items |
