The alert rate is the number of NEWS2 scores that reach threshold per 100 patients per postadmission day. NEWS2 score were analysed from day 1 to day 56 of admission, excluding the first day of elective admission. Index-NEWS2 reports the first NEWS2 recorded in each post-admission day. All-NEWS2 includes all scores recorded in the admission spell. Highest-NEWS2 reports the highest score recorded in each post-admission day. The WTE clinician resource required to service clinical response recommendations at different thresholds, assumed 1 hour per deployed response and an annual clinician workload=1760 hours. NEWS2 were excluded from analysis in the presence of a DNACPR decision or when the patient was on ICU.
DNACPR, do-not-attempt-cardiopulmonary-resuscitation; ICU, intensive care unit; NEWS2, National Early Warning Score 2; WTE, whole time equivalent.
