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.

In the immediate aftermath of a disaster, household members may experience lack of support services and isolation from one another. To address this, a common recommendation is to promote preparedness through the preparation of an emergency supply kit (ESK). The goal was to characterize ESK possession on a national level to help the Centers for Disease Control and Prevention (CDC) guide next steps to better prepare for and respond to disasters and emergencies at the community level.

The authors analyzed data collected through Porter Novelli’s ConsumerStyles surveys in fall 2020 (n = 3625) and spring 2021 (n = 6455).

ESK ownership is lacking. Overall, while most respondents believed that an ESK would help their chance of survival, only a third have one. Age, gender, education level, and region of the country were significant predictors of kit ownership in a multivariate model. In addition, there was a significant association between level of preparedness and ESK ownership.

These data are an essential starting point in characterizing ESK ownership and can be used to help tailor public messaging, inform work with partners to increase ESK ownership, and guide future research.
