The prevalence of systemic lupus erythematosus (SLE) in the United States is not known.
The estimates that are available have been based on populations in small geographic areas
with unique demographic characteristics, or on telephone surveys [1]. These estimates
range widely from 5.8 to 1000 per 100,000 people [1-3]. Having current nationally
representative estimates of the prevalence of SLE would increase our understanding of the
burden of disease and help in health care planning. We applied a new method that …
The prevalence of systemic lupus erythematosus (SLE) in the United States is not known. The estimates that are available have been based on populations in small geographic areas with unique demographic characteristics, or on telephone surveys [1]. These estimates range widely from 5.8 to 1000 per 100,000 people [1-3]. Having current nationally representative estimates of the prevalence of SLE would increase our understanding of the burden of disease and help in health care planning.
We applied a new method that combines data on the frequency with which patients are hospitalized with data from state inpatient hospital databases to estimate the prevalence of SLE in adults (aged 18 or older) in California and Pennsylvania [4]. California, through its Office of Statewide Health Planning and Development, and Pennsylvania, through the Health Care Cost Containment Council, mandate that hospitals report discharge abstracts for each hospitalization annually. Abstracted data include patient age, sex, race, and discharge diagnoses (up to 25 in California, up to 8 in Pennsylvania), as well as encrypted unique patient identifiers to identify individuals with multiple hospitalizations. From these databases, we identified the number of adults in each state who had a hospitalization in 2000 that included
