The aim of this study was to evaluate the effects of age, sex, race, ethnicity, cost of hospitalization, length of stay, and payor source on SLE disease severity scores.
DESIGN: Epidemiological study.
SETTING: Hospital discharge data were obtained from the DFW Hospital Council (DFWHC), for 65,535 patients hospitalized in the North Texas Dallas-Fort Worth (DFW) Metropolitan Statistical Area (MSA) from 1999-2005 with at least one autoimmune disease.
PATIENTS: Of the 65,535 autoimmune patients, 14,829 patients had SLE as a diagnosis. The sample was assessed for disease severity according to the SLE comorbidity Index. MAIN
OUTCOME: Disease severity, SLE comorbidities.
RESULTS: SLE patients were younger and more than five times more likely to have multiple autoimmune diseases. More than one third of Hispanic patients were on Medicaid or self-pay and more likely to have higher disease severity. Race (Caucasian), sex (female), and payor source (PPO/POS) predicted lower disease severity scores. SLE was predictive of eight of the fourteen SLE-CI diseases, with greatest effects observed for nephritis (OR = 3.30, P < .0001), chronic renal failure (OR = 3.36, P < .0001), pericarditis (OR = 3.2, P < .0001), and pleuritis (OR = 2.06, P < .0001). Non-Caucasian patients were more likely to have chronic renal failure, nephritis, congestive heart failure, pericarditis and pleuritis.
CONCLUSIONS: The comorbidities that exist in SLE vary according to ethnicity. It is paramount for physicians to be cognizant of these disparities and make appropriate referrals. | | Language | eng | | Pub Type(s) | Journal Article
