The changing role of the World Bank in global health.

The World Bank began operations on June 25, 1946. Although it was established to finance European reconstruction after World War II, the bank today is a considerable force in the health, nutrition, and population (HNP) sector in developing countries. Indeed, it has evolved from having virtually no presence in global health to being the world's largest financial contributor to health-related projects, now committing more than $1 billion annually for new HNP projects. It is also one of the world's largest supporters in the fight against HIV/AIDS, with commitments of more than $1.6 billion over the past several years. I have mapped this transformation in the World Bank's role in global health, illustrating shifts in the bank's mission and financial orientation, as well as the broader changes in development theory and practice. Through a deepened understanding of the complexities of development, the World Bank now regards investments in HNP programs as fundamental to its role in the global economy.

Analysis of costs, length of stay, and utilization of emergency department services by frequent users: implications for health policy.

UNLABELLED: In efforts to decrease emergency department (ED) crowding and health care costs, frequent users of ED services have been targeted for interventions to decrease their utilization. Previous studies have had different definitions for "frequent users" and have considered all frequent users as a homogeneous group. To the authors' knowledge, no study has examined visit characteristics and resource utilization of different levels of frequent use. OBJECTIVES: 1) to determine the rates of ED utilization by five user groups defined by number of annual visits, 2) to examine variations in visit characteristics by frequency of ED use, and 3) to compare levels of resource utilization among frequent user groups. METHODS: This was a retrospective, cross-sectional study of clinical and financial records for all ED visits to an urban, academic hospital in 2001. Multinomial logistic and linear regression models were used for analyses. Estimates were corrected for multiple comparisons (with Bonferroni corrections), where applicable, and adjusted for clustering within individuals (with Huber-White estimators). Outcome measures were triage acuity, diagnosis-related group (DRG) severity, disposition status, primary complaint, medical diagnosis, hospital inpatient length of stay, payment method, costs, and demographics. RESULTS: Patients with three to 20 visits were more likely to be admitted to the hospital than patients visiting once or twice. Patients visiting more than 20 times were less likely to require hospital admission and more likely to present with "nonurgent" conditions, have lower severity scores, and elope or leave the ED without medical attention than patients visiting the ED once. The group had fewer inpatient days and lower average costs than patients visiting once. Patients with six to 20 visits had traditional Medicaid coverage more often than those with one or two visits. Virtually no patients visiting more than 20 times had Medicare or Medicaid managed care, a health maintenance organization, or a preferred provider organization. CONCLUSIONS: Frequent ED users are a heterogeneous group. Many patients previously thought to overutilize the ED for socioeconomic or insignificant medical problems are as sick as less-frequent ED users. There is a small subgroup with more than 20 visits who are less ill or injured but also incurred lower-than-average costs per visit.

Association between insurance status and admission rate for patients evaluated in the emergency department.

OBJECTIVES: To determine if differences exist in hospital and intensive care unit (ICU)/operating room admission rates based on health insurance status. METHODS: This was a retrospective, cross-sectional study of data from hospital clinical and financial records for all 2001 emergency department (ED) visits (80,209) to an academic urban hospital. Hospital admission and intensive care unit (ICU)/operating room admissions were analyzed, controlling for triage acuity, primary complaint, diagnosis, diagnosis-related group (DRG) severity, and demographics. Multivariate logistic regression models identified factors associated with hospital admission for under insured (self-pay and Medicaid) compared with other insured (private health maintenance organization, preferred provider organization, worker's compensation, and Medicare) patients. RESULTS: Compared with the other insured group, under insured patients were less likely, overall, to be admitted to the hospital (odds ratio [OR], 0.82; 95% CI = 0.76 to 0.90), controlling for all other factors studied. Subgroup analysis of common complaints showed under insured patients with a chief complaint of abdominal pain (OR, 0.67; 95% CI = 0.55 to 0.80) or headache (OR, 0.61; 95% CI = 0.39 to 0.95) had the lowest adjusted ORs for admission to the hospital, compared with other insured patients. Under insured patients with DRG of "menstrual and other female reproductive system disorders" (OR, 0.17; 95% CI = 0.06 to 0.51) or "esophagitis, gastroenteritis, and miscellaneous digestive disorders" (OR, 0.55; 95% CI = 0.28 to 0.96) also were less likely to be admitted compared with the other insured group. No significant differences in ICU/operating room admission rates were found between insurance groups. CONCLUSIONS: Whereas there was no difference in admission rates to the ICU/operating room by insurance status, this single-center study does suggest an association between insurance status and admission to a general hospital service, which may or may not be causally related. Factors other than provider bias may be responsible for this observed difference.
