Brief summary
This study assessed the impact of a task-focusing strategy on perceived stress levels and performance during a simulated CPR scenario.
Detailed description
Background: Cardiopulmonary resuscitation (CPR) causes significant stress, which may cause deficiencies in attention and increase distractibility. This may lead to misjudgements of priorities and delays in CPR performance, which may further increase mental stress (vicious cycle). Aim: This study assessed the impact of a task-focusing strategy on perceived stress levels and performance during a simulated CPR scenario. Methods: This is a prospective, randomized-controlled trial Setting: Simulator-center of the University Hospital Basel, Switzerland. Participants: A total of 124 volunteer medical students Intervention: Randomization to receive a 10 minute instruction to cope with stress by loudly posing two task-focusing questions (what is the patient's condition?, what immediate action is needed?) when feeling overwhelmed by stress (intervention group) or a control group. Outcome measures: The primary outcome is the perceived levels of stress and feeling overwhelmed (stress/overload); secondary outcomes were hands-on time, time to start CPR and number of leadership statements.
Interventions
BEHAVIORALStress coping
Students in the intervention group received a 10 minute instruction to cope with stress. They were informed that an emergency situation is a stressful experience for health care workers and that perceived stress may interfere with their decision-making abilities and performance. Particularly, feeling overwhelmed by stress may cause cognitive impairment potentially leading to loss of concept how to deal with an emergency situation, which in turn further increases stress (vicious cycle). However, it is possible to overcome this situation by focusing on the basic conditions of the situation and the immediate actions that are needed. They were instructed that they should ask two task-focusing questions aloud (what is the patient's condition?, what immediate action is needed?) to overcome the negative consequences of feeling overwhelmed by stress.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Average level of stress/overload during the resuscitation period | In the first 120 seconds after the onset of the cardiac arrest | The primary outcome was the average level of stress/overload during the resuscitation period for the experimental and the control group. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| hands-on time | in the first 120 seconds after the onset of the cardiac arrest. | Medical performance measures: hands-on time defined as duration of uninterrupted chest compressions and defibrillation in the first 120 seconds after the onset of the cardiac arrest. |
| time elapsed until CPR was started | in the first 120 seconds after the onset of the cardiac arrest | the time elapsed until CPR was started, defined as the time to the first meaningful measure (either defibrillation, chest compression or ventilation) after the onset of the cardiac arrest; the team coordination measure |
| leadership statements | in the first 120 seconds after the onset of the cardiac arrest | Number of leadership statements coded, using a predefined checklist containing the following categories based on previous research |
