Deadly Degrees: Don't Discount These Diagnoses

Temperature is a critical vital sign that can influence workup and clinical diagnosis in the emergency department. Although temperature derangement is often environmentally mediated, it is important to consider other causes. Fever can be attributed to infections, inflammatory processes, endocrine dysfunctions, or adverse reactions to medications. Similarly, hypothermia may be the result of shock, endocrine disorder, malnutrition, or iatrogenic factors. An understanding of the impact of temperature on physiology, diagnostics, and patient outcomes enables early recognition of underlying pathologic condition and supports appropriate clinical intervention.
