Hurricane-related flooding significantly disrupts home health care services, extending treatment durations by an average of nearly 13 days and reducing the likelihood that patients can successfully return to their communities. A research letter published in JAMA Health Forum indicates that the decentralized nature of these services leaves both providers and patients highly vulnerable during extreme weather events, which can sever communication, block access to homes, and halt the delivery of essential medical supplies.
Impact of Extreme Weather on Home Health Outcomes
The study, which examined data from Hurricane Sandy—a superstorm that struck the Caribbean and the northeastern United States in late October 2012—found that patients in flooded areas faced distinct clinical and logistical challenges. According to the National Oceanic and Atmospheric Administration (NOAA), Hurricane Sandy resulted in at least 117 deaths in the U.S. and caused more than $68 billion in damage, ranking it as the second-costliest storm in U.S. history after Hurricane Katrina.

To understand the specific effects on home-based care, researchers analyzed Medicare Part A and Part B beneficiaries who were receiving home health services at the time of the storm’s landfall on October 29, 2012. The study cohort included 761 beneficiaries, with an average age of 77.3 years, split between those residing in ZIP codes affected by flooding and those in nearby, non-flooded areas. Both groups were statistically similar regarding chronic conditions such as congestive heart failure and Alzheimer’s disease.
Data Findings: Treatment Delays and Recovery
The findings revealed a clear disparity in care continuity. Patients living in areas untouched by flooding were more likely to receive a timely start of care and were more frequently discharged back to their communities. In contrast, those in flooded regions experienced an average of 12.9 additional days of treatment. While the study did not find a statistically significant change in medication management or discharge rates to skilled nursing facilities, the overall disruption to home-based recovery remained substantial.
“Extreme weather events may inflict widespread disruption in an already decentralized system and network of [home health care],” the study’s authors stated. The research highlighted that agency nurses and other medical professionals were often physically prevented from reaching patients’ homes, while the interruption of communication systems further complicated the management of patient care.
Integrating Home Health into Emergency Planning
The results of this analysis suggest that the current emergency management framework may not adequately account for the complexities of the home health sector. The authors of the study emphasized that these findings “underscore the vulnerability of [home healthcare] recipients to flooding and invite further questions about the incorporation of [home healthcare] into broader health care emergency planning efforts at local and regional levels.”
Because the data was limited to 2012, the researchers noted that their findings could not control for specific home health agency characteristics, nor were they necessarily generalizable to the modern Medicare Advantage population. Nevertheless, the study provides a foundational look at how climate-related disasters intersect with the growing reliance on home-based medical care for older, vulnerable populations.
As climate patterns shift and the frequency of severe weather events potentially increases, health policy experts and emergency planners face a growing need to fortify the logistical resilience of home health agencies. Ensuring that these decentralized networks have robust contingency plans for communication and supply chain management remains a critical priority for protecting patient safety during and after large-scale environmental disasters.
