Beyond coverage and supply: measuring access to healthcare in today's market

To stimulate discussion within the research and policy community about the value of and issues surrounding different ways to describe access to care in a health system reconfigured by the growth of managed care, competition, and other marketplace changes.

The concept of access has evolved over time to address shifting health policy concerns like the growing interest in looking beyond utilization as a measure of access to a better consideration, too, of the effectiveness of services used as judged by costs and outcomes. Yet current frameworks used to look at access are person-based and do not capture the complexity of the healthcare system and the complex structures involved in managed care organizations that combine delivery and financing and vary substantially within and across markets. In addition, many at times competing or conflicting policy goals on access exist. There also is an increasingly diverse and widening set of uses that include benchmarking against national goals, measuring performance of accountable entities, and providing consumer information.

Traditional access frameworks are invaluable in encouraging focus on historical measures of access, like insurance coverage and other barriers to system entry. But much greater attention needs to be paid to adapting current access frameworks so that they also better support the ability to understand how processes inherent in diverse health delivery and financing arrangements influence access to services within a system and what this means for how well individuals negotiate healthcare systems and the effects on care outcomes. The increasing demands on access measures and the growing diversity of users also point to a need for collaboration to better pool insights, share experiences, and honestly confront trade-offs or disagreements to progress in addressing these issues.
