Abbreviations: AACC, age-adjusted Charlson comorbidity; KS, Kolmogorov-Smirnov test.
a
Vital sign documentation count is 48 hours after hospital admission. Vital sign documentation frequency was above and beyond the minimum standard requirement. The sample size was too small for cardiac arrest patients with AACC scores of 0 to ≥6, so only acute care patients are included.
b
Independent samples t test (2-tailed, equal variances not assumed).
c
Post-hoc power analysis for t test.
