Abstract

Background: Obesity is escalating in the southeastern (SE) USA and is associated with multiple disease risks. Obese COPD patients may differ from traditional non-obese or cachectic patients with COPD. Aims: 1) to identify differences in patient characteristics related to body mass index (BMI), a measure of obesity. 2) to determine if there were significant differences in rehospitalization and annual cost of care between COPD patients who were and were not overweight/obese. Methods: Descriptive, comparative, retrospective record analysis. All patients discharged in 2004 with physician diagnosed COPD from an academic health science center in the SE US were included. BMI>25kg/m²= overweight; BMI>30kg/m²=obese. Results: 34/83 (41%) had information to calculate BMI. Females 53% (n=18); mean age 66; 35% (n=12) African American(AA); 29%(n=10) married. Over 76% were overweight/obese. Obese patients had a higher percentage of diagnosed diabetes, heart failure, hypertension, and psychiatric illness. Mean BMI for AAs (37.8kg/m²) vs. non-AAs(28.5kg/ m²) was significant(p=.047). Readmitted patients had a mean BMI of 34.9kg/m² vs. non-readmitted patients with 27. 9kg/m² (p=.072). Annual cost: non-overweight/obese $10,191/patient; overweight/obese $40,027/patient. Conclusions: Respiratory professionals need to document height and weight (BMI). Patient characteristic of race for AAs significantly related to BMI. While readmitted patients had a higher mean BMI than non-readmitted patients, significance could not be determined due to the small sample size; there was a definite trend toward significance. Elevated BMI interacting with race (AA) should be further studied as potential predictors of readmission.
