Emergency supply kits (ESKs) may support disaster-related self-sufficiency and may be important for people with chronic health conditions (CHCs). However, evidence of ESK’s effectiveness in supporting self-sufficiency is lacking. This study examined associations between households possessing ESKs and 1) household members leaving home for medicine and 2) individuals with CHCs seeking medical care.

Data were collected through a survey distributed to southwest Florida after Hurricane Ian’s impact (n = 1342). Associations were assessed using logistic regression models.

ESK possession was more common among households with members with CHCs (63%) than households without such members (56%). Overall, regression models revealed no clear association between ESK possession and leaving home for medicine (adjusted Odds Ratio (aOR)=1.27; CI = 0.81-2.02). Analyses restricted to households with individuals with CHCs revealed no clear associations between ESK possession and leaving the home for medicine (aOR= 1.35; CI = 0.81-2.25) or seeking medical care (aOR = 1.07; CI = 0.68-1.68).

This study did not provide evidence that ESKs promote medical self-sufficiency. However, it did not characterize the medication in households’ ESKs or the type, duration, and severity of CHCs, and could have had uncontrolled confounding. Characterization of such factors would be important in future studies of ESKs and self-sufficiency among people with CHCs.
