The analytical results indicate that nursing accreditation
level is positively related to patient safety (b = 0.11,
t = 2.26, P = 0.02 < 0.05, part correlation = 0.11),
supporting the study hypothesis. One potential expla-
nation for this finding is that nurses with a high
accreditation level have advanced expertise and skills
that affect their ability to achieve a high level of patient
safety. Moreover, the addition of the nursing accreditation level as a predictor significantly increases
the R
2
value (DR
2
= 0.01, F
= 5.12, P = 0.03
< 0.05), indicating that nursing accreditation has substantial
influences on patient safety. Table 3 lists the
test results.
