Delays and errors in cardiopulmonary resuscitation and defibrillation by pediatric residents during simulated cardiopulmonary arrests.

BACKGROUND: The quality of life support delivered during cardiopulmonary resuscitation affects outcomes. However, little data exist regarding the quality of resuscitation delivered to children and factors associated with adherence to American Heart Association (AHA) resuscitation guidelines. PARTICIPANTS: Pediatric residents from an academic, tertiary care hospital. DESIGN: Prospective, observational cohort study of residents trained in the AHA PALS 2000 guidelines managing a high-fidelity mannequin simulator programmed to develop pulseless ventricular tachycardia (PVT). MAIN OUTCOME MEASURES: Proportion of residents who: (1) started compressions in < or =1min from onset of PVT, (2) defibrillated in < or =3min and (3) factors associated with time to defibrillation. RESULTS: Seventy of eighty (88%) residents participated. Forty-six of seventy (66%) failed to start compressions within 1min of pulselessness and 23/70 (33%) never started compressions. Only 38/70 (54%) residents defibrillated the mannequin in < or =3min of onset of PVT. There was no significant difference in time elapsed between onset of PVT and defibrillation by level of post-graduate training. However, residents who had previously discharged a defibrillator on either a patient or a simulator compared to those who had not were 87% more likely to successfully defibrillate the mannequin at any point in time (hazard ratio 1.87, 95% CI: 1.08-3.21, p=0.02). CONCLUSIONS: Pediatric residents do not meet performance standards set by the AHA. Future curricula should focus training on identified defects including: (1) equal emphasis on "airway and breathing" and "circulation" and (2) hands-on training with using and discharging a defibrillator in order to improve safety and outcomes.

The use of cognitive AIDS during simulated pediatric cardiopulmonary arrests.

BACKGROUND: Management of pediatric cardiopulmonary arrest (CPA) is challenging because of the low volume of experience of most pediatric health care providers. Use of cognitive aids may assist in making rapid decisions in these crises; however, there are no known published reports on whether these aids are actually used during arrest management and whether they impact quality of care. METHODS: Sixty pediatric residents participated in individual simulated CPA scenarios, which involved pulseless ventricular tachycardia and pulseless electrical activity. Our primary outcome measure was the proportion of pediatric residents who used cognitive aids during simulated CPAs. Secondary outcome measures were to quantify 1) type of aids used, 2) category of use, and 3) human errors made during resuscitation efforts. RESULTS: Eighty-five percent of residents voluntarily used a cognitive aid to assist in managing simulated pediatric CPAs. The most commonly used aids were an American Heart Association Pediatric Advanced Life Support aid and an institutionally created aid. Forty-three of 51 (84.3%) and 23 of 46 (60.5%) residents used these aids for assistance with the pulseless ventricular tachycardia and pulseless electrical activity algorithm, respectively. Unfortunately, 13 of 51 (25.5%) residents chose the incorrect treatment algorithm, resulting in inappropriate management. CONCLUSION AND APPLICATION: Although the majority of residents chose to use cognitive aids for assistance, errors in management were common. Further study is required to determine whether these errors are associated with cognitive aid design flaws and whether improving their design through human factors research can help minimize errors in Basic and Advanced Life Support, ultimately improving patient outcomes.
