ABSTRACT

BACKGROUND: Obstetric hemorrhage is the leading cause of maternal mortality, particularly in low resource settings where delays in obtaining definitive care contribute to high rates of death. The non-pneumatic anti-shock garment (NASG) first-aid device has been demonstrated to be highly cost-effective when applied at the referral hospital (RH) level. In this analysis we evaluate the incremental cost-effectiveness of early NASG application at the Primary Health Center (PHC) compared to later application at the RH in Zambia and Zimbabwe. METHODS: We obtained data on health outcomes and costs from a cluster-randomized clinical trial (CRCT) and participating study hospitals. We translated health outcomes into disability-adjusted life years (DALYs) using standard methods. Econometric regressions estimated the contribution of earlier PHC NASG application to DALYs and costs, varying geographic covariates (country, referral hospital) to yield regression models best fit to the data. We calculated cost-effectiveness as the ratio of added costs to averted DALYs for earlier PHC NASG application compared to later RH NASG application. RESULTS: Overall, the cost-effectiveness of early application of the NASG at the primary health care level compared to waiting until arrival at the referral hospital was $21.78 per DALY averted ($15.51 in added costs divided by 0.712 DALYs averted per woman, both statistically significant). By country, the results were very similar in Zambia, though not statistically significant in Zimbabwe. Sensitivity analysis suggests that results are robust to a per-protocol outcome analysis and are sensitive to the cost of blood transfusions. CONCLUSIONS: Early NASG application at the PHC for women in hypovolemic shock has the potential to be cost-effective across many clinical settings. The NASG is designed to reverse shock and decrease further bleeding for women with obstetric hemorrhage; therefore, women who have received the NASG earlier may be better able to survive delays in reaching definitive care at the RH and recover more quickly from shock, all at a cost that is highly acceptable.

ABSTRACT

OBJECTIVE: To study pregnant women's knowledge, attitudes and behaviors towards tobacco use and secondhand smoke (SHS) exposure, and exposure to advertising for and against tobacco products in Zambia and the Democratic Republic of the Congo (DRC). DESIGN: Prospective cross-sectional survey between November 2004 and September 2005. SETTING: Antenatal care clinics in Lusaka, Zambia, and Kinshasa, DRC. POPULATION: Pregnant women in Zambia (909) and the DRC (847). METHODS: Research staff administered a structured questionnaire to pregnant women attending antenatal care clinics. MAIN OUTCOME MEASURES: Pregnant women's use of tobacco, exposure to SHS, knowledge of the harms of tobacco and exposure to advertising for and against tobacco products. RESULTS: Only about 10% of pregnant women reported ever having tried cigarettes (6.6% Zambia; 14.1% DRC). However, in the DRC, 41.8% of pregnant women had tried other forms of tobacco, primarily snuff. About 10% of pregnant women and young children were frequently or always exposed to SHS. Pregnant women's knowledge of the hazards of smoking and SHS exposure was extremely limited. About 13% of pregnant women had seen or heard advertising for tobacco products in the last 30 days. CONCLUSIONS: Tobacco use and SHS exposure pose serious threats to the health of women, infants and children. In many African countries, maternal and infant health outcomes are often poor and will likely worsen if maternal tobacco use increases. Our findings suggest that a 'window of opportunity' exists to prevent increased tobacco use and SHS exposure of pregnant women in Zambia and the DRC.

ABSTRACT

OBJECTIVES: We examined pregnant women's use of cigarettes and other tobacco products and the exposure of pregnant women and their young children to secondhand smoke (SHS) in 9 nations in Latin America, Asia, and Africa. METHODS: Face-to-face surveys were administered to 7961 pregnant women (more than 700 per site) between October 2004 and September 2005. RESULTS: At all Latin American sites, pregnant women commonly reported that they had ever tried cigarette smoking (range: 78.3% [Uruguay] to 35.0% [Guatemala]). The highest levels of current smoking were found in Uruguay (18.3%), Argentina (10.3%), and Brazil (6.1%). Experimentation with smokeless tobacco occurred in the Democratic Republic of the Congo and India; one third of all respondents in Orissa, India, were current smokeless tobacco users. SHS exposure was common: between 91.6% (Pakistan) and 17.1% (Democratic Republic of the Congo) of pregnant women reported that smoking was permitted in their home. CONCLUSIONS: Pregnant women's tobacco use and SHS exposure are current or emerging problems in several low- and middle-income nations, jeopardizing ongoing efforts to improve maternal and child health.

ABSTRACT

BACKGROUND: One of the remaining challenges in the prevention of mother-to-child transmission of HIV is to reduce the risk of the transmission during pregnancy. It remains to be investigated which factors affect intrauterine HIV transmission and how they can be identified and addressed during pregnancy. METHODS: Granulocyte elastase in the endocervical mucus of HIV-positive pregnant women in Zambia was measured, and its association with intrauterine transmission of HIV-1 from the mother to the fetus was investigated. RESULTS: The intrauterine transmission rate determined by polymerase chain reaction assay of DNA from neonates at birth was 15.3%. The risk for intrauterine transmission was 8.65-fold higher in women who were positive for granulocyte elastase than in those who were negative. CONCLUSION: We suggest that the women showing positive granulocyte elastase at delivery be strongly suspected of having and if having had chorioamnionitis during pregnancy, which could affect the intrauterine transmission of HIV.
