Final answer:
Burnout is a state of chronic stress leading to exhaustion, depersonalization, and diminished personal accomplishment, seriously affecting one's work effectiveness in healthcare.
Step-by-step explanation:
The state of exhaustion and irritability that develops over a longer period of time, leading to a marked decrease in one's effectiveness in delivering emergency medical care, is referred to as burnout. This condition emerges from chronic workplace stress that has not been successfully managed. It includes three dimensions: emotional exhaustion, where a person feels drained and has nothing more to give at a psychological level; depersonalization, leading to a detached or indifferent attitude towards people one is serving; and a sense of diminished personal accomplishment, feeling unsatisfied with one's job-related accomplishments or having failed to influence others positively through work.
