Patient Centered Medical Homes: RHIO déjà vu
Regional Health Information Organizations (RHIOs) gained limelight in 2004 when President Bush called for Electronic Health Records for every American by 2014. The primary objective of RHIOs was to create an interoperability and information sharing infrastructure so that 360 degree view or complete medical history of patient’s health records can be made available for healthcare decision making. The desired outcomes were improved quality of care, prevention of clinical errors, elimination of redundant tests or care, prevention of adverse reactions, better care coordination and reduction in healthcare costs. The concept of Patient Centered Medical Homes (PCMHs), also called Medical Homes, goes back to its introduction by the American Academy of Pediatrics in 1967. However this primary care model has gained popularity over last one year as President Obama rolled out healthcare reforms. Patient Centered Medical Home is a care model where primary care physician is responsible for complete care coordination of the patient. Primary care physician collaborates with other physicians and care organizations based on the care needs of the patient and also educate the patient on self-health management. PCMHs share the same goals as RHIOs in terms of improved quality of care, better care coordination, better clinical outcomes and reduced healthcare costs.
Although there is shared objective, the key difference lies in how the RHIOs and PCMH s are organized and operate. RHIOs are collaborative organization of varied composition involving some or all of the organizations like federal agencies, state agencies, non-profit community organizations, hospitals, safety net providers, individual practitioners, pharmacies academia and insurers. PCMH are physician practice associations that follow “Medical Home” care model principles. While RHIOs focus on building an information sharing structure and all the participating providers/insurers have the onus of sharing health information for enhanced quality of care delivery, in PCMH the primary care physicians or a personal physician of the patient carries the responsibility for care coordination and sharing health information across the care team.
RHIOs have seen limited success. According to a survey of 109 RHIOs produced in 2005 by eHealth Initiative Foundation, top two obstacles to RHIOs were identified as sustainability/ funding and user adoption. Most RHIOs started with an initial grant for demonstration pilots but they lacked sustainable, financially viable business models. There was an unaddressed challenge of inequitable distribution of costs and benefits. While providers had to make large upfront investments in implementation of healthcare IT and development of interoperability infrastructure, financial benefits of improved outcomes and reduced inappropriate care goes to payers. Most of the providers did not have Electronic Medical Record systems and EMR adoption issues were a barrier to their participation in RHIOs. Workflows for unstructured, paper based health records sharing were not planned for in most cases.
Electronic Medical Records system adoption by physician practices has received an impetus from ARRA healthcare IT incentives for Meaningful Use of EMR. However, PCMHs continue to face the very same challenge of inequitable distribution of costs and benefits as did the RHIOs. There is no one clear winner in reimbursement strategies that physicians and payers are willing to embrace. One of the principles in "Joint Principles of the Patient-Centered Medical Home” released in 2007 by leading primary care physician organizations is: “Payment must appropriately recognize the added value provided to patients who have a patient-centered medical home. For instance, payment should reflect the value of work that falls outside of the face-to-face visit, should support adoption and use of health information technology for quality improvement, and should recognize case mix differences in the patient population being treated within the practice.” The commonly used reimbursement models of Fee for Service and Capitation provide no incentives to primary care physicians to make additional IT investments and spend more time and effort in coordinating care. Pay for Performance strategy of payers account for added incentives for demonstrating improved outcomes in certain clinical metrics. But are these incentives adequate to cover the cost of additional responsibilities that Medical Home physician undertakes? It is to be seen if providers and payers can find the winning reimbursement strategy to make PCMHs a great success or will PCMHs go the RHIO way?
