The Criterion Validity, Reliability, and Feasibility of an Instrument for Assessing the Nursing Intensity in Perioperative Settings

Table 2

Nursing intensity scores in different ASA categories.

Phase	ASA I (); Mean/median (IQR); Min–max	ASA II (); Mean/median (IQR); Min–max	ASA III (); Mean/median (IQR); Min–max	ASA IV (); Mean/median (IQR); Min–max
Pre phase	6.8/6.0	7.2/7.0	8.2/8.0	12.3/12.5	<0.0001
	(6.0–7.0)	(6.0–8.0)	(6.0–10.0)	(12.0–13.0)
	6–11	6–12	6–13	8–16
	Intra phase	9.9/10.0	10.4/10.0	12.1/12.0		16.1/17.0	<0.0001
(8.0–11.0)		(8.0–12.0)	(9.0–15.0)	(14.0–19.0)
6–20		6–22	6–22	7–24
Post phase		8.4/8.0	8.5/8.0	9.6/9.0	11.1/10.0	<0.0001
	(7.0–10.0)	(7.0–10.0)	(7.0–12.0)	(9.0–14.0)
	6–20	6–15	6–18	6–19

IQR = interquartile range; -Wallis test; significant differences in pairwise comparisons between ASA categories with Mann–Whitney tests using Bonferroni-corrected values: In pre phase I versus III (), I versus IV (), II versus IV (), and III versus IV (); in intra phase I versus III (), I versus IV (), II versus III (), II versus IV (), andn III versus IV (); in post phase I versus III (), I versus IV (), II versus III (), and II versus IV (). Three patients in ASA category V were excluded from the analysis. ASA category VI did not appear in our data.
