Effect of comorbidity score (CM) on various indicators for brain tumor patients

Indicator	For linear relationships (no graphic), or for having indicator multiplied by X for each unit increase in comorbidity score
AHRQ indicators
Pressure ulcer	X = 1.43, CI = [1.40, 1.46], P < .0001
Iatrogenic pneumothorax	X = 1.07, CI = [1.04, 1.09], P < .0001
Central venous line infection	Risk is estimated to increase quickly for low CM scores but more slowly for higher scores (P > .0001) (Fig 1).
Postoperative hip fracture	X = 1.25, CI = [1.22, 1.28], P < .0001
Postop physiologic derangement, any	Risk is estimated to increase quickly for low CM scores, but more slowly for higher scores (P > .0001) (Fig 2).
Postoperative hemorrhage	X = 1.12, CI = [1.08, 1.16], P < .0001
Postoperative respiratory failure	X = 1.39, CI = [1.38, 1.41], P < .0001
Deep vein thrombosis	X = 1.24, CI = [1.23, 1.25], P < .0001
Pulmonary embolism	X = 1.36, CI = [1.35, 1.38], P < .0001
Sepsis	Risk is estimated to increase quickly for low CM scores, but more slowly for higher scores (P > .0001) (Fig 3).
Accidental puncture or laceration	P > .05
Hospital acquired conditions
Pressure ulcer stages III–IV	Risk is estimated to increase quickly for low CM scores, but more slowly for higher scores (P > .0001) (Fig 4).
Falls and trauma, any	Risk is estimated to increase quickly for low CM scores, but more slowly for higher scores (P > .0001) (Fig 5).
Vascular catheter-associated infection	Risk is estimated to increase quickly for low CM scores, but more slowly for higher scores (P > .0001) (Fig 6).
Manifestations of poor glycemic control, any	X = 1.51, CI = [1.47, 1.54], P < .0001
Catheter-associated UTI	X = 1.19, CI = [1.09, 1.30], P = .0002
