We report three cases of pleuropericarditis complicating the clinical course of inflammatory bowel disease. This extraintestinal complication developed in all three patients during the quiescent phase of the disease. One patient had ulcerative colitis, while two patients had Crohn's disease. Aspirin and/or indomethacin were effective in treating two of the(More)
This paper evaluates a new method for assessing hospital admission severity of illness based on disease-specific models (logistic regression) of the probability of in-hospital mortality. Results for the 26 disease groups in MDC 4--Diseases of the Respiratory System, MDC 5--Diseases of the Circulatory System, and MDC 6--Diseases of the Digestive System are(More)
The Medical Illness Severity Grouping System--called MEDISGRPS--is an admission-oriented patient severity grouping system that uses objective, key clinical findings to place patients in one of five severity groupings. Data from five hospitals indicate that severity level at admission is an important predictor of resource use, is essential for analysis of(More)
Hospital financial managers have come to recognize that to profitably operate a hospital under DRGs, they must consider factors other than length of stay. They must also look at illness severity, medical care effectiveness, and treatment efficiency. It is therefore advantageous to develop a method that measures the effect of admission severity on DRG(More)
The possibility that the unreliability of urinary excretion of radioactivity after the administration of oral 131I-triolein, as a measure of fat absorption, is due to variable renal clearance of iodide prompted investigation of a double-radioisotopic method. Intravenously administered radioiodide should be cleared identically with radioiodide split from(More)
Information systems for severity-of-illness measurement and case mix adjustment are at the cutting edge of health care quality technology. The rapid rise of these systems in the past decade has paralleled hospital needs for better data on clinical processes and the burgeoning need among health care customers for better data on clinical outcomes and the(More)
Recognition of the need for measuring quality has increasingly permeated the thinking of leaders in industry. Until relatively recently, however, measuring health care quality was a novel concept. For many reasons a variety of constituencies have begun to see the need for information about the quality of health care. Here, we describe a particular model for(More)
