RESUMO
Estimating blood demand to determine collection goals challenges many low-income countries. We sampled Tanzanian hospitals to estimate national blood demand. A representative sample based on probability proportional to size sampling of 42 of 273 (15%) Tanzanian transfusing hospitals was selected. Blood bank registers, patient medical records, and blood component disposition records were reviewed prospectively from June to September 2013 to determine the number of components requested and the number and proportion issued, not issued due to nonavailability, and not issued for other reasons. Data were estimated for an annual national estimate. Of an estimated 278 371 components requested in 2013, 6648 (2.4%) were not issued due to nonavailability, 34 591 (12.4%) were not issued for other reasons, and 244 535 (87.8%) were issued. Of these 278 371 components, 86 753 (31.2%) were requested by adult medical, 74 499 (26.8%) by pediatric medical, and 57 312 (20.6%) by obstetric units. In these 3 units, the proportion of units not issued due to nonavailability was 1.8%. Private (4.1%) and large (6%) hospitals had the largest proportion of units not issued because of nonavailability. Of 244 535 issued components, 91 690 (37.5%) were collected, tested, and issued from blood banks that are not part of the Tanzania National Blood Transfusion Services (TNBTS). Nearly 98% of blood component demand was met. However, a large portion of the blood supply for the hospitals came from non-TNBTS blood banks. TNBTS could increase availability of safe blood through assuring the quality of donor selection and donation testing at non-TNBTS blood banks.

BACKGROUND AND OBJECTIVES: Antibiotic resistance is a growing problem that complicates the treatment of various illnesses. This study analyzes Medicaid encounter data to (1) determine antibiotic prescribing rates for common respiratory tract infections in Oregon and (2) assess the effect of receiving an antibiotic at an index visit on whether there was a return visit within 30 days. METHODS: Subjects included in this study were Medicaid patients in Oregon between 2001--2003 who were enrolled in Medicaid for a full year and were diagnosed with an upper respiratory tract infection, including bronchitis, sinusitis, acute otitis media (AOM), pharyngitis, and upper respiratory infections (URIs). Claims data were analyzed to determine receipt of an antibiotic within 3 days of the initial visit and if there was a return visit within 30 days. RESULTS: During 2001--2003, the proportion of patients receiving antibiotics for bronchitis and sinusitis decreased, from 70% to 61%, and from 78% to 74%, respectively, while antibiotic prescribing for AOM, URI, and pharyngitis changed little. After controlling for age, gender, race/ethnicity, Medicaid plan type, and location, we determined that patients who had received antibiotics during the index visit for AOM, URI, and pharyngitis were more likely to return with a respiratory tract infection during the subsequent 30 days than patients who did not receive antibiotics. CONCLUSIONS: Antibiotic prescribing among Medicaid patients in Oregon has decreased. Receiving an antibiotic does not decrease the rate of subsequent return visits.

OBJECTIVE: Obtaining childhood immunization coverage data for small geographic areas is difficult and resource-intensive, especially in the absence of comprehensive immunization registries. To identify factors that are associated with delayed immunization, we collected school-entry immunization records statewide and used geocoding to link to publicly available census tract sociodemographic data. METHODS: Immunization records were reviewed for children who were enrolled in all public and private school kindergarten programs in Hawaii in the 2002-2003 school year; immunization status at the time of the second birthday was determined. The main outcome variable was up-to-date status for the 4:3:1:3:3 vaccination series (4 doses of diphtheria-tetanus-pertussis, 3 doses of polio, 1 dose of measles-mumps-rubella, 3 doses of Haemophilus influenzae type b, and 3 doses of hepatitis B vaccines). Children's home addresses were geocoded to census tracts; coverage rates by tract were mapped, and sociodemographic data from Census 2000 files were used to identify factors that were associated with delays in immunization. RESULTS: Records were obtained for 15,275 of 15,594 children registered in Hawaii kindergartens. Overall, 78% had completed their 4:3:1:3:3 series by their second birthday. Risk factors for delayed immunization included delayed immunization at 3 months of age, living in Maui County, living in a neighborhood where a low proportion of adults had postsecondary education, and living in a neighborhood where a high proportion of households spoke a language other than English at home. The majority (80%) of underimmunized children would have required only 1 additional visit to bring them up-to-date. CONCLUSIONS: Retrospective review of kindergarten-entry immunization data revealed geographic areas with lower immunization coverage, and geocoding to census tracts identified associated sociodemographic risk factors. This is a practical method for state or city health departments to identify pockets of need and to direct resources appropriately.

BACKGROUND: The relationship between domestic funding for selected conditions to the Centers for Disease Control and Prevention (CDC) and the burden of disease and disability in the United States was assessed systematically. METHODS: Using mortality, years of potential life lost (YPLLs), disability-adjusted life years (DALYs), hospital days, hospital discharges, and direct medical costs of conditions, 34 high-burden conditions addressed by CDC programs were identified, and information was collected about the funds spent on each by CDC during fiscal year (FY) 2003. The 34 conditions were grouped into 15 categorical areas, and the relationship between budget and burden was analyzed using correlation and regression methods for each of the categorical areas and for each measure of burden. RESULTS: Of CDC's total FY 2003 budget of $6.9 billion, 62% ($4.3 billion) of funding was allocated to one of the 34 conditions studied. A positive relationship between budget and burden was identified for all measures of burden, although the correlations varied for the different conditions. CONCLUSIONS: Although examination of the relationship of CDC's budget to burden measures provides insight into the agency's portfolio of investments, this exercise also highlights a number of limitations with this approach and the currently available burden measures. Assessment of key public health functions such as emergency preparedness and the collection of vital statistics require development of metrics different from the burden measures used in this analysis. Investment in the development of such metrics warrants consideration.

Few data are available on the epidemic of childhood overweight in local jurisdictions. To determine the prevalence and identify demographic and socioeconomic correlates of childhood overweight, we assessed height and weight data on 281,630 Los Angeles County, CA, public school students collected during school-based physical fitness testing in 2001. Overweight prevalence was 20.6% overall and varied by race/ethnicity: 25.2% among Latinos, 20.0% among Pacific Islanders, 19.4% among blacks, 17.6% among American Indians, 13.0% among whites, and 11.9% among Asians. By using multilevel analysis, we found that school-level percentage of students enrolled in free or reduced-price meal programs was independently associated with overweight, after controlling for school-level median household income and student-level demographic characteristics. When local overweight prevalence data are unavailable, percentage enrollment in free or reduced-price meal programs might be a useful indicator to identify schools where focused overweight prevention and control interventions are most needed.

PURPOSE. This study examines whether psychosocial perinatal care services developed through community partnerships and cultural deference with attention to individual women's health issues, had an assocaited impact on use of prenatal care, birth outcomes and perinatal care costs for the three participating Asian Pacific Islander American ethinc groups. METHODS. The use of prenatal care visits and birth outcomes for women in the Malama program were compared to those for women of the same etnic groups in the community prior to the introduction of the program. Data on program participants from 1992 to 1994 were compared to birth certificate data on Hawaiian, Filipino and Japanese women from 1988 to 1991. Costs of providing Malama prenatal services were determined from data provided by cost accounting and encounter data systems for the program. SUMMARY OF IMPORTANT FINDINGS. The use of prenatal care visits and birth outcomes were significantly lower for Malama program participants than for women of the same ethnic groups prior to the introduction of the program. The costs of the prenatal program services were $846 to $920 per woman. The expected savings in medical costs per infant with the improved preterm birth rates were $680 per infant. Thus 75% to 80% of the costs of the services were likely to be saved in lower medical costs of the infants. MAJOR CONCLUSIONS. Programs that use community approaches and caring servies delivered in a cultural context, like the Malama model, have a potential for improving the use of prenatal care and birth outcomes at reasonable costs. RELEVANCE TO ASIAN PACIFIC ISLANDER AMERICAN POPULATIONS. The Malama approach to ascertaining cultural preferences for the content and delivery of care should prove useful in addressing public health goals of improved pregnancy outcomes for diverse groups of Asian Americans and Pacific Islanders. KEY WORDS. Asian Americans/Pacific Islanders, pregnancy, prenatal care, low birthweight, preterm birth, cultural competency, community partnerships, costs, cost effectiveness.
