Objectives: To examine the hospitalization rate and mortality associated with forced mass transfer of nursing home (NH) residents with the highest levels of functional impairment.
Design: Retrospective cohort study.
Setting: One hundred nineteen Texas and Louisiana NHs identified as being at risk for evacuation for Hurricane Gustav.
Participants: Six thousand four hundred sixty-four long-stay residents residing in at-risk NHs for at least three consecutive months before landfall of Hurricane Gustav.
Measurements: Using Medicare claims and instrumental variable analysis, the mortality (death at 30 and 90 days) and hospitalization rates (at 30 and 90 days) of the most functionally impaired long-stay residents who were evacuated for Hurricane Gustav were compared with those of the most functionally impaired residents who did not evacuate.
Results: The effect of evacuation was associated with 8% more hospitalizations by 30 and 90 days for the most functionally impaired residents. Evacuation was not significantly related to mortality.
Conclusion: The most functionally impaired NH residents experience more hospitalizations but not mortality as a consequence of forced mass transfer. With the inevitability of NH evacuations for many different reasons, harm mitigation strategies focused on the most impaired residents are needed.
