For the purposes of multivariable analysis, these 83 operative categories were then grouped into 37 operation clusters (labeled 1 to 37; Table 1).
Much more could be described and explained, but what I have discussed leads us to several major operative categories of traditional Chinese thought, foundational to both Confucianism and Taoism.
The number of procedures in each of 83 operative categories for both the control period and the intervention phase was collated to allow comparison.
Thus, methods resulting in minor to moderate operative trauma (Category 1) were those requiring analgesia and rehabilitation support after surgery only to obtain full recovery, whereas methods resulting in major operative trauma were those also requiring advanced clinical care and post-surgical hospitalization (Category 2) [ 14].
10 Incidence of SSI was calculated, using the NNIS operative procedure categories.
The rate of POH was substantial in virtually all of the 12 operative procedure categories.
The rate of POH varied from 14.3% to 57.9% among 11 of the 12 operative procedure categories (Table 3).
Initial operative risk categories for 90-day in-hospital mortality were calculated from the cutoff points defined by the ROC curve obtained with the overall point score.
On this basis, patients were classified into seven operative risk categories, which were later re-grouped into four: low (≤90 points), medium (91to105 points), high (106 to 128 points) and very high (>128 points).
POH rate varied from 14%to58%8% among 11 of 12 operative procedure-categories. Conditions independently associated with POH (p < 0.05) were acute trauma, BMI, ASA level, glycopyrrolate administration, and duration of surgery.
