New York, NY, December 15, 2008Interruptions in Medicaid coverage are associated with a higher rate of hospitalization for conditions that can often be treated in an ambulatory care setting, including asthma, diabetes, and hypertension, according to a new study in today's issue of the Annals of Internal Medicine. The analysis, which examines interrupted Medicaid coverage and hospitalization rates, finds that increased risk for hospitalization is highest in the first three months after an interruption in Medicaid coverage.
The study suggests that when states require enrollees to demonstrate eligibility on a more frequent basis, they may see an increase in hospitalizations for common health conditions: lacking insurance to cover the costs of primary care, many former Medicaid enrollees end up in hospitals and are then re-enrolled in Medicaid. The study of California adults, conducted by researchers at San Francisco General Hospital (SFGH) Medical Center and University of California San Francisco (UCSF), was supported by the Commonwealth Fund.
Federal rules require states to re-determine Medicaid beneficiary eligibility at least once every 12 months but some states do so more often. During most of the time of this study, 1998 to 2002, Californiawhich has the largest Medicaid program in the U.S.required beneficiaries to report on their eligibility every 3 months. California has since reduced the frequency of eligibility determination.
"Although states may attempt to save money in the short term by dropping Medicaid coverage for those who cannot keep up with frequent reporting requirements, this study shows that disruptions in coverage come at the risk of increased hospitalization for conditions that can typically be treated in a less expensive primary care setting," said lead author Andrew B. Bindman, M.D., a professor of medicine at UCSF and chief of general internal medicine at SFGH.
