• Respiratory: presence of apnea or cyanosis was absent
from the CHEWS; oxygen flow rates on the CHEWS
was too high for younger patients; and respiratory rate
range limits of the CHEWS did not accommodate the
wide age range of patients, especially the newborns
and infants.
The tool was then modified to account for these variables
and became the Cardiac Children's Hospital Early Warning
Score (C-CHEWS) tool. A second pilot was conducted with
the new C-CHEWS tool using the previously described
methods (n=53; observations=312). Analysis of the data
collection revealed 7.5% (n=4) of the patients' C-CHEWS
scores did not correlate with the acuity of their clinical
picture, however this time it was an equal mix of patients
