The dominant model for payment of medical services has been a “payment for procedure” model which financially encourages vendors to provide as many medical procedures as possible without a financial incentive for a good outcome. Escalating costs have triggered experiments with other payment models that focus on value. Earlier this decade, “pay for performance” took center stage as a tactic for realigning payment with value. Another model known as “bundled payments” is being studied at the state and national level. One or combinations of these newer models may at some point determine payment under California workers’ compensation.
Bundled payment is a single payment to providers or health care facilities (or jointly to both) for all services to treat a given condition or provide a given treatment. Bundled payment asks providers to assume financial risk for the cost of services for a particular treatment or condition, as well as costs associated with preventable complications. Just 1.6 percent of payments currently flowed through bundled payment models. However, use of bundled payments is growing in both the public and private sectors. The Centers for Medicare and Medicaid Services (CMS) Bundled Payments for Care Improvement (BPCI) Initiative will pilot bundled payments in almost 100 settings (ranging from hospitals to nursing homes) over the next three years, and the program is expanding further. Both Tennessee and Arkansas are working to implement multi-stakeholder episode-based payment initiatives.
Traditionally, Medicare makes separate payments to providers for each service they perform (pay for procedure model) for beneficiaries during a single illness or course of treatment. This approach can result in fragmented care with minimal coordination across providers and health care settings. It also rewards the quantity of services offered by providers rather than the quality of care furnished. Research has shown that bundled payments can align incentives for providers – hospitals, post-acute care providers, physicians, and other practitioners – allowing them to work closely together across all specialties and settings. The Bundled Payments for Care Improvement initiative was developed by the Center for Medicare and Medicaid Innovation (Innovation Center). The Innovation Center was created by the Affordable Care Act to test innovative payment and service delivery models that have the potential to reduce Medicare, Medicaid, or Children’s Health Insurance Program (CHIP) expenditures while preserving or enhancing the quality of care for beneficiaries.
The Bundled Payment model has now caused researchers to focus on the cause of costly “bad” medical and surgical outcomes, research that is desperately needed. A new study from researchers at NYU Langone’s Hospital for Joint Diseases identifies common causes of hospital readmissions following total hip and knee arthoplasty procedures. By finding these common causes, researchers believe quality can be increased and hospital costs decreased. The study was presented at the American Academy of Orthopaedic Surgeons Annual Meeting in Las Vegas.
The patients were part of the Bundled Payment for Care Initiative from the Centers for Medicare and Medicaid Services (CMS), a government pilot program where hospitals are paid for quality of procedures rather than quantity. One way to measure quality is by examining hospital readmission rates. Researchers studied 721 patients admitted to NYU Langone’s Hospital for Joint Diseases between January and December 2013 for a total hip arthoplasty (THA) or total knee arthoplasty (TKA). Of those cases, 80 patients, or 11 percent, had to be re-admitted within 90 days.
THA and TKA readmissions due to surgical complications accounted for 54% and 44% of the indications for readmissions, respectively. Surgical complications included infection (11), wound complications (8) bleeding (7), periprosthetic fracture (5), dislocations (4), and post-surgical pain (4). The average cost of readmission for surgical complications was $36,038 for THA and $61,049 for TKA. Medical complications included gastrointestinal disease (11), pulmonary disease (8), genitourinary/renal complications (6), hematologic (6), cardiovascular (3), endocrine disorders (2) syncope (2), rheumatologic (1), lumbago (1), and an open ankle wound (1). The average cost of medical complications was $22,775 for THA and $10,283 for TKA patients, respectively.
“While some complications are unavoidable, we are proud of our low readmission rates at the Hospital for Joint Diseases and by identifying the causes for readmission, we hope to reduce our rates even further,” says study co-author Joseph Bosco, MD, associate professor and Vice Chair for Clinical Affairs in the Department of Orthopaedic Surgery at NYU Langone. “As bundled payment programs are implemented more widely nationwide, other U.S. hospitals will follow our example and implement strategies to boost quality and reduce medical costs.”
