Personal health records (PHRs) are a rapidly expanding area in medical informatics due to the belief that they may improve healthcare delivery and control costs of care. To truly understand the full potential value of a technology, a cost analysis is critical. However, little evidence exists on the value potential of PHRs, and a cost model for PHRs does not currently exist in the literature.#R##N##R##N#This paper presents a sample cost model for PHR systems, which include PHR infrastructure and applications. We used this model to examine the costs of provider-tethered, payer-tethered, third-party, and interoperable PHRs. Our model projects that on a perperson basis, third-party PHRs will be the most expensive followed by interoperable PHRs, and then provider-tethered PHRs and payer-tethered PHRs are the least expensive. Data interfaces are a major cost driver, thus these findings underscore the need for standards development and use in the implementation of PHR systems.
