Creating a More Resilient Safety Net for Persons with Chronic Disease: Beyond the “Medical Home”

Mega-disasters the scale and scope of Hurricane Katrina have been exceedingly rare in the USA. Nonetheless, careful study of such disasters can provide lessons learned that can lend essential insights to guide planning for future events of any size.1 Such disasters can also expose previously under-recognized frailties in society that, like the under-built levees of New Orleans, readily buckle under stress. One such frailty exposed by the storm was the health care safety net. Katrina was in many ways the “perfect storm” not only because of her meteorological characteristics but because she struck a portion of the world with high prevalence of chronic conditions, high rates of uninsured, and a geographically and financially consolidated safety net system.2 At the heart of the devastated area was the Medical Center of Louisiana at New Orleans (formerly known as Charity Hospital), the primary source of first-contact and chronic disease care for hundreds of thousands of uninsured and underinsured persons in the Greater New Orleans area. Katrina’s devastating flood rendered this Center completely inoperable. This confluence of events left hundreds of thousands of vulnerable patients with chronic conditions in the most densely populated hurricane-affected areas suddenly with no access to care. In this issue of JGIM, the Hurricane Katrina Community Advisory Group present the findings of their telephone survey assessing the impact of Hurricane Katrina of survivors with chronic disease among a sample from New Orleans and other affected areas.3 In their large representative sample, one in five persons reported having cut back or terminated treatment for a major chronic illness after the hurricane. Characteristics independently associated with treatment disruption included age younger than 65, having fewer relatives within and beyond hurricane-affected areas, and suffering two or more geographic relocations by early 2006, roughly 4–6 months after the disaster. Insurance was not an independent predictor in multivariable analysis, but this variable may have been difficult to disentangle from age, given the role of Medicare. Their complementary listing of respondents’ self-reported reasons for treatment interruption highlighted limited access to physicians and medications, insurance/payment issues, and competing demands for patient’s time and attention. These factors are strikingly similar to those reported in research among Americans experiencing homelessness in the absence of major humanitarian disasters.4,5 Minimizing disruption to the care of persons with chronic disease requires weaving a health care safety net resilient to the stress of disasters and to the more personalized disasters such as job loss or loss of one’s home.6 The design of a resilient health care safety net should pivot on recognition that continuing care for patients with chronic illness and their associated complex needs requires sufficiently nuanced policies. We posit that a health care safety net, capable of caring for patients with chronic disease during routine times and disasters, must take account not one, but three types of “homes”, each interdependent and supporting the other. Health care policies to shore up the safety net should drive the development of a web-enabled “medical home”,4,5 a portable financing mechanism for their care, an “insurance home”, and sufficient social support and resources to allow for self-care and management sufficient to help them respond to life’s challenges, a “social home”.
