A5.Do you know the risk factors for ICU-AW?

0.87

A6.Do you know the preventive measures of ICU-AW?

0.91

A7.Did you know that critically ill children could also develop ICU-AW?

0.85

A8.ICU-AW symptoms are muscle weakness with no clear cause in critically ill patients, clinically manifested as difficulty in weaning, paresis or quadriplegia, decreased reflexes, and muscle atrophy.

0.55

A9.ICU-AW includes polyneuropathy in critically ill patients, myopathy in critically ill patients, and critical neuromuscular diseases.

0.73

A10.The diagnosis of ICU-AW is mainly determined by the Medical Research Council Score (MRC-score).

0.70

A11.Does the MRC-score use the Oxford Muscle Strength Scale to evaluate the six major muscle groups of the body?

0.84

A12.ICU-AW not only prolongs the hospital stay and increases medical costs, but also reduces the patient’s ability to live and survive.

0.65

A13. Braking may be an important risk factor for ICU-AW.

0.58

A14. Early mobilization of ICU patients is the most effective intervention to prevent or mitigate ICU-AW in patients.

0.69

A15. Standard insulin therapy can reduce the incidence and duration of neuromuscular complications, thereby reducing ICU-AW.

0.74

B1. Do you agree that your knowledge of ICU-AW needs to meet clinical needs?

0.53

B2. Do you think the PICU medical staff should observe the patient’s ICU-AW status dynamically like adults?

0.86

B3. Do you think PICU medical staff should receive formal ICU-AW training?

0.90

B4. Do you think ICU-AW should be assessed as seriously as other complications (pressure ulcers, infections, etc.)?

0.91

B5. Do you think early functional exercise is very important for the prevention and recovery of ICU-AW?

0.87

B6. Do you think healthcare workers should focus on ICU-AW prevention as much as other symptoms (e.g., delirium)?

0.90

B7. Do you think it is the nurses and not others (doctors, technicians) who should assess the muscle strength of the child?

0.76

B8. Do you think the ICU-AW status of critically ill patients should be included in the handover content of clinical work?

0.77
