Frostbite Injuries in Chicago's Unsheltered Population

Area of Science:

• Public Health
• Environmental Medicine
• Epidemiology

Background:

• People experiencing unsheltered homelessness (PEUH) face elevated risks of cold-related injuries like frostbite.
• Frostbite can lead to severe morbidity, including amputation, disproportionately affecting vulnerable populations.

Purpose of the Study:

• To determine the prevalence, incidence, and impact of frostbite among PEUH in Chicago and surrounding suburbs.
• To assess the frequency and circumstances of frostbite injuries within this population.

Main Methods:

• A survey was administered to assess frostbite injury frequency and related circumstances.
• Data collection occurred at a Chicago Transit Authority metro station in suburban Cook County.

Main Results:

• Frostbite is common in PEUH, with an incidence rate of 1271.67 cases per 100,000 life-years.
• The study found a high morbidity rate, with 46.24 amputations per 100,000 life-years due to frostbite.

Conclusions:

• Frostbite poses a significant health threat to PEUH in Chicago, necessitating targeted interventions.
• Increased collaboration with street medicine partners is crucial for awareness and advocacy.
• Improved emergency preparedness plans are vital to mitigate frostbite impact during winter seasons.
