* Basel III calls for 7 pct ratio for top-level capital.
PCT concentrations in intra-abdominal infections can be useful when deciding the time frame for on-demand laparotomy, and a PCT ratio cutoff value of 1.03 has been proposed to predict successful elimination of the intra-abdominal infection source [ 43].
Novotny et al. more recently found in 104 patients with secondary peritonitis that PCT ratio appears to be helpful in distinguishing between patients with successful eradication of the septic focus and those with a persisting infectious focus [ 48].
Furthermore IL-6, PCT, cortisol, ratio Tau/A β1-42, A β1-40, And A βN-40 were in total the 10 best, with delirium-associated biomarkers (all P < 0.10) in univariate logistic regression analysis.
In seven PCTs the highest percentage of short stay admissions (0 to 3 day) discharged on the day of admission was more than two times greater than the lowest and in three of these PCTs this ratio was greater than 3, and in one (PCT c) greater than 4 (Table 5).
Prior to the study we chose the following cut off levels for reporting sensitivities, specificities, positive predictive values, negative predictive values, positive likelihood ratios and negative likelihood ratios: PCT, 0.1 ng/ml, 0.25 ng/ml and 0.5 ng/ml; LBP, 20 μg/ml and 40 μg/ml; CRP, 50 mg/l and 100 mg/l; and IL-6, 25 pg/ml and 50 pg/ml.
ACTH, adreno corticotropic hormone; CI, confidence interval; OR, odds ratio; PCT, procalcitonin.
AUC, area under the receiver operating characteristic curve; CI, confidence interval; ICU, intensive care unit; OR, odds ratio; PCT, procalcitonin.
Randomisation took place after referral to the PCT: an unequal ratio was felt to be more acceptable to ward staff and was adopted in an attempt to facilitate recruitment.
APACHE = Acute Physiology and Chronic Health Evaluation CPISS = clinical pulmonary infection score; CRP = C-reactive protein; ICU = intensive care unit; HCPA = Hospital de Clínicas de Porto Alegre ORR = odds ratio; PCT = procalcitonin; QEA = quantitative endotracheal aspirate; SOFA = Sequential Organ Failure Assessment; VAP = ventilator-associated pneumonia.
APACHE: Acute Physiology, Age and Chronic Health Evaluation; AUC: area under the curve; CI: confidence interval; CRP: C-reactive protein; LOS: length-of-stay; OR: odds ratio; PCT: procalcitonin; ROC: receiver operating characteristic.
