RESEARCH DESIGN AND METHODS— We analyzed 1,376 patients with diabetes who were >65 years of age and in the 1993 Medicare Current Beneficiary Survey. Morbidity measures were the Katz Index of Activities of Daily Living, Instrumental Activities of Daily Living, overall health perception, Charlson Comorbidity Index score, and diabetic complications. Quality of care standards were glycosylated hemo...

Patients with prostate cancer have an increased risk of stroke, but their absolute rate of stroke depends on age and comorbid conditions. The Charlson Comorbidity Index Score (CCIS) is a widely accepted measure for risk adjustment in administrative claims data sets. This study assesses the predictive value of CHADS2 scores and CCIS for stroke among patients with prostate cancer. The study was c...

BACKGROUND There is increasing interest in clinical research with electronic medical data, but it often faces the challenges of heterogeneity between hospitals. Our objective was to develop a single numerical score for characterizing such heterogeneity via computing inpatient mortality in treating acute myocardial infarction (AMI) patients based on diagnostic information recorded in the databas...

BACKGROUND Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity in the elderly population. COPD leads to a reduced health-related quality of life (HRQL), but the factors which contribute to this are not well understood. A better understanding of the factors which determine HRQL should lead to an improved care for such patients. OBJECTIVES The purpose of this study was to...

OBJECTIVE To determine the preoperative and perioperative predictive factors of morbidity/mortality in patients undergoing percutaneous nephrolithotomy (PCNL), using the Clavien's classification. MATERIALS AND METHODS We performed a retrospective chart review of patients who underwent PCNL between January 2005 and January 2012. Preoperative and postoperative factors, such as age, obesity, sur...

Background: Charlson Comorbidity Index[1] is a tool including age and chronic diseases assessing the comorbidity burden. The burden in RA patients determine morbidity mortality. Objectives: To assess classification of CCI with usage health-care system (outpatient clinics) real-world setting. Methods: 327 from large outpatient service central hospital were retrospectively reviewed. Demographic c...

AIMS To identify patient factors that are associated with a higher risk of comorbidity, and to assess the impact of comorbidity on risk of in-hospital death, length of stay and 5-year all-cause survival among a large cohort of patients with colon cancer in New Zealand. METHODS Comorbidity data were collected from patients who were diagnosed with colon cancer and admitted to public hospitals d...

BACKGROUND The risk factors for mortality after hospitalization in older persons are not fully understood. The aim of the present study was to examine the three-year (1,096 days) mortality in previously hospitalized older patients from rural areas, and to explore how objectively and self-reported health indicators at baseline were associated with mortality. METHODS The study included 484 (241...

BACKGROUND There is limited and conflicting information on the use of co-morbidity instruments to predict mortality in patients with chronic obstructive pulmonary disease (COPD). METHODS We sought to test the validity of the Charlson Index and another co-morbidity instrument, the Adult co-morbidity evaluation 27 (ACE-27), in patients admitted with COPD exacerbations. Co-morbidity scores were ...
