The fact sheet “Acute Care and Extreme Heat: Recommendations and Information for Health Care Workers”provides practical guidance for medical staff managing patients during heat waves. It emphasizes that acute care settings must proactively prepare to treat heat-related illnesses, including heat exhaustion and heat stroke, by implementing protocols for early identification and swift intervention. Recommendations include ensuring patient hydration, using cooling techniques like fans and wet towels, and monitoring vital signs such as temperature, heart rate, and hydration status. The document advocates for staff training on heat illness recognition, internal communication plans, and readiness for emergencies. It also underscores environmental controls—optimizing indoor temperature, improving ventilation, and scheduling high-risk procedures during cooler periods. By integrating these measures into standard operating procedures, health care facilities can enhance patient safety and reduce heat-related morbidity. This resource supports resilience in health systems facing increasing extreme heat risks, equipping care workers with actionable tools to manage climate-related health impacts.
