What Is Decision Fatigue?
Decision fatigue is the deterioration of decision-making quality after a long session of making choices. Every clinical decision you make during an EMS shift, from choosing an airway adjunct to selecting a transport destination, draws from a finite pool of mental energy. As that pool depletes over a 12- or 24-hour shift, your decisions become less careful, more impulsive, or default to the easiest option rather than the best one.
How Decision Fatigue Manifests in EMS
Decision fatigue in EMS can look like:
- Defaulting to the nearest hospital instead of the most appropriate facility
- Skipping assessment steps because "it is probably just..." a routine call
- Avoiding difficult conversations with patients about refusal risks
- Taking shortcuts in documentation
- Becoming irritable with patients, partners, or dispatch
- Difficulty focusing on complex clinical presentations late in the shift
The Science Behind It
Research shows that decision quality declines as the number of decisions increases. This is true across professions: judges grant fewer paroles later in the day, surgeons have higher complication rates at the end of long shifts, and physicians order more unnecessary antibiotics as the day progresses. EMS providers are not immune to this effect, especially when running multiple calls with minimal downtime.
Coping Strategies
You cannot eliminate decision fatigue, but you can manage it. Reduce the number of non-essential decisions you make during a shift by using routines: eat the same types of meals, follow the same equipment check process, and use the same documentation templates. This preserves mental energy for clinical decisions that truly require your full attention.
Take breaks when possible. Even a 10-minute break between calls can partially restore your decision-making capacity. Eat regular meals and stay hydrated, as low blood sugar and dehydration accelerate mental fatigue. Use checklists and protocols as cognitive aids rather than relying on memory, especially during high-acuity calls late in your shift.
Recognize when your decision-making is impaired. If you catch yourself cutting corners or feeling apathetic about a patient's complaint, that is a signal to slow down, re-engage with your assessment process, and ask your partner for a second opinion on your clinical plan.
