Adaptive index models for marker-based risk stratification.
We use the term "index predictor" to denote a score that consists of K binary rules such as "age > 60" or "blood pressure > 120 mm Hg." The index predictor is the sum of these binary scores, yielding a value from 0 to K. Such indices as often used in clinical studies to stratify population risk: They are usually derived from subject area considerations. In this paper, we propose a fast data-dri...
متن کاملHostile Abdomen Index Risk Stratification and Laparoscopic Complications
BACKGROUND Common life-threatening complications associated with laparoscopy, including bleeding and inadvertent enterotomy, are described in the literature. We investigated the application of the Hostile Abdomen Index related to these complications. We hypothesize that the preoperative score may guide a surgeon in risk stratification. METHODS We used data from Monmouth Medical Center morbidi...
متن کاملRisk stratification, risk adjustment, and other risks.
“BUT our patients are sicker than yours!” is the refrain when physicians are faced with adverse comparisons of their patients’ outcomes with those of other groups, hospitals, or health systems. Meaningful and fair comparison of clinical performance requires statistical adjustment of outcomes for differences in clinical acuity of patients treated and complexity of procedures performed, among oth...
متن کاملRisk Stratification of Patients with Peripheral Arterial Disease and Abdominal Aortic Aneurysm Using Aortic Augmentation Index
BACKGROUND Central augmentation index (cAIx) is an indicator for vascular stiffness. Obstructive and aneurysmatic vascular disease can affect pulse wave propagation and reflection, causing changes in central aortic pressures. AIM To assess and compare cAIx in patients with peripheral arterial disease (PAD) and / or abdominal aortic aneurysm (AAA). METHODS cAIx was assessed by radial applana...
متن کاملRapid risk stratification for obstructive sleep apnea, based on snoring severity and body mass index.
OBJECTIVE It is unclear whether all snoring patients require polysomnography, and there are no highly sensitive clinical predictors of sleep apnea. Our objective was to develop a simple clinical screening test for OSA in snoring patients. STUDY DESIGN Prospective, IRB-approved study at a university sleep disorders center. SUBJECTS AND METHODS In 211 patients undergoing polysomnography, snor...
