The Agency for Health Care Policy and Research (AHCPR) works to improve the quality of health care, reduce costs, and broaden access to essential services. Here are some of the findings described in the October issue of AHCPR's Research Activities, a monthly publication that reports the results of studies supported by AHCPR.
Adjusting Capitation Rates May Not Prevent Discrimination Against Chronically Ill Children
Capitation of risk-adjustment methods, which adjust capitated rates to compensate managed care plans for increased costs associated with chronic medical problems, are one approach being used to eliminate the financial incentive to discriminate against children with chronic conditions. However, children with chronic health problems—such as asthma and diabetes—would probably remain at risk for discrimination in a competitive health care market even under risk-adjusted rates, according to a study conducted by Elizabeth J. Fowler, Ph.D., and Gerard F. Anderson of Johns Hopkins University. Regardless of the capitation adjustment method used, this study found significant underpayment to providers of care to high-risk children.

Costs of Outpatient Care Are Cut In Half When A Patient Sees A Primary Care Physician First
Health maintenance organizations typically require patients to contact their primary care physicians first for any new medical problem. This first-contact approach to health care can save more than half of outpatient expenditures, concludes an AHCPR-supported study conducted by Christopher B. Forrest, M.D., Ph.D., and Barbara Starfield, M.D., M.P.H., of The Johns Hopkins School of Public Health. The study found that consulting a primary care clinician first instead of a specialist or other source of care reduced overall outpatient expenditures 53 percent, expenses for acute illnesses by 62 percent, and expenses for preventive care by 20 percent. Overall, increasing the current level of first-contact care just 10 percent would save at least $1.1 billion per year (1993 dollars).

Earlier Referral To Hospice Care May Benefit Terminally Ill Elderly Patients
Earlier referral to hospice care may improve the quality of remaining life of terminally ill elderly patients, yet many enter hospice care when they have a only few weeks left to live. According to an AHCPR-supported study, entering hospice care earlier also would allow these patients to receive Medicare-covered noncurative medicine and support services that would not be covered in the hospital, say researchers Nicholas Christakis, M.D., Ph.D., and Jose J. Escarce M.D., of the University of Pennsylvania. Although earlier referral of patients to hospice care would increase Medicare costs for such care, these savings might be more than offset by the savings realized through reducing more expensive hospital costs.

Increased Risk of Preterm Birth Among Pregnant Black Women May Be Due in Part to Higher Rate of Vaginal Infections
Black women have two to three times more preterm births than white women, and the gap appears to be increasing. A study funded by AHCPR suggests that the disparity may be linked to a higher incidence of vaginal infections in black women. Results of a multivariate analysis conducted by Robert L. Goldenberg, M.D., of the University of Alabama at Birmingham, indicates that black women were two to six times more likely than white women to have vaginal infections that are associated with preterm births. They are: Chlamydia trachomatis (16 percent vs. 5 percent), Neisseria gonorrhoeae (2.5 percent vs. 0.4 percent), Bacteroides sp. (25 percent vs. 14 percent), and bacterial vaginosis (23 percent vs. 9 percent). Other physical, behavioral, and socioeconomic characteristics of the women did not explain the large racial difference in preterm births.
