RESUMO

INTRODUCTION: Delivering preventive chemotherapy through mass drug administration (MDA) is a central approach in controlling or eliminating several neglected tropical diseases (NTDs). Treatment coverage, a primary indicator of MDA performance, can be measured through routinely reported programmatic data or population-based coverage evaluation surveys. Reported coverage is often the easiest and least expensive way to estimate coverage; however, it is prone to inaccuracies due to errors in data compilation and imprecise denominators, and in some cases measures treatments offered as opposed to treatments swallowed. OBJECTIVE: Analyses presented here aimed to understand (1) how often coverage calculated using routinely reported data and survey data would lead programme managers to make the same programmatic decisions; (2) the magnitude and direction of the difference between these two estimates, and (3) whether there is meaningful variation by region, age group or country. METHODS: We analysed and compared reported and surveyed treatment coverage data from 214 MDAs implemented between 2008 and 2017 in 15 countries in Africa, Asia and the Caribbean. Routinely reported treatment coverage was compiled using data reported by national NTD programmes to donors, either directly or via NTD implementing partners, following the implementation of a district-level MDA campaign; coverage was calculated by dividing the number of individuals treated by a population value, which is typically based on national census projections and occasionally community registers. Surveyed treatment coverage came from post-MDA community-based coverage evaluation surveys, which were conducted as per standardised WHO recommended methodology. RESULTS: Coverage estimates using routine reporting and surveys gave the same result in terms of whether the minimum coverage threshold was reached in 72% of the MDAs surveyed in the Africa region and in 52% in the Asia region. The reported coverage value was within ±10 percentage points of the surveyed coverage value in 58/124 of the surveyed MDAs in the Africa region and 19/77 in the Asia region. Concordance between routinely reported and surveyed coverage estimates was 64% for the total population and 72% for school-age children. The study data showed variation across countries in the number of surveys conducted as well as the frequency with which there was concordance between the two coverage estimates. CONCLUSIONS: Programme managers must grapple with making decisions based on imperfect information, balancing needs for accuracy with cost and available capacity. The study shows that for many of the MDAs surveyed, based on the concordance with respect to reaching the minimum coverage thresholds, the routinely reported data were accurate enough to make programmatic decisions. Where coverage surveys do show a need to improve accuracy of routinely reported results, NTD programme managers should use various tools and approaches to strengthen data quality in order to use data for decision-making to achieve NTD control and elimination goals.

RESUMO

Noncommunicable diseases (NCDs) are the leading cause of death in the world, and 80% of all NCD deaths occur in low- and middle-income countries (LMICs). The COVID-19 pandemic has demonstrated that patients with NCDs are at increased risk of becoming severely ill from the virus. Disproportionate investment in vertical health programs can result in health systems vulnerable to collapse when resources are strained, such as during pandemics. Although NCDs are largely preventable, globally there is underinvestment in efforts to address them. Integrating health systems to collectively address NCDs and infectious diseases through a wide range of services in a comprehensive manner reduces the economic burden of healthcare and strengthens the healthcare system. Health system resiliency is essential for health security. In this article, we provide an economically sound approach to incorporating NCDs into routine healthcare services in LMICs through improved alignment of institutions that support prevention and control of both NCDs and infectious diseases. Examples from Zambia's multisector interventions to develop and support a national NCD action plan can inform and encourage LMIC countries to invest in systems integration to reduce the social and economic burden of NCDs and infectious diseases.

RESUMO

Data sharing between housing and education agencies will provide housing agencies with resources to assist them with efforts to decrease segregation and mitigate the adverse health outcomes experienced by people of color. The Fair Housing Act has the potential to fulfill its original integrationist purpose if housing and education agencies combine resources and data to create and implement fair housing plans. The Biden Administration's restored rule to affirmatively further fair housing pursuant to the Fair Housing Act of 1968 which seeks to reduce segregation and increase housing equity. However, it omits most of the processes set forth by the Obama Administration whereby federal agencies provide the proper tools to housing agencies so that they are able to make data-based decisions about housing policies. This article advocates for the sharing of data between housing and education agencies to optimize the positive impact of fair housing not only within housing, but also on the education, employment, and health opportunities for communities of color.

RESUMO

BACKGROUND: Globally, data on antenatal blood transfusion practices are scarce. We sought to characterize the epidemiology of antenatal transfusion in South Africa. STUDY DESIGN AND METHODS: A cross-sectional study was conducted of women who were transfused during pregnancy (>48 hr before anticipated delivery) at two hospitals in Durban and Soweto in 2014 to 2015. Medical record data on demographics, obstetric history, anemia, HIV status, and indications for blood transfusion were abstracted. RESULTS: The records on a total of 560 transfused pregnant women were evaluated; mean age was 28 years, 98% were of black African ethnicity, and 28% were HIV positive. At time of transfusion, one-half were in the first trimester. Hemorrhage was noted in 76% of women, most of which was associated with abortion (67%) or ectopic pregnancy (27%). Most women were transfused with red blood cells (RBCs; median, 2 units); 14% of women were transfused with plasma and 2% with platelets. Median pre- and posttransfusion hemoglobin levels were 6.9 g/dL and 9.2 g/dL, respectively; the latter differed by hospital (8.7 g/dL vs. 9.5 g/dL; p < 0.01). Hemorrhage was associated with missing HIV status, lower gestational age, and transfusion of 3 or more RBC units (all p < 0.01). In contrast, diagnoses of anemia (Soweto only) were associated with HIV infection, later gestational age, and lower (<3 units) RBC dose (all p < 0.01). CONCLUSION: Abortion and ectopic pregnancy with associated hemorrhage were the leading indications for antenatal transfusion and were concentrated in early gestation. By contrast, anemia was associated with HIV infection and transfusion in the third trimester.

RESUMO

Circumstances within the military environment may place military personnel at increased risk of contracting sexually transmitted infections including HIV. Since 2005, RTI International has provided technical assistance to the Seroprevalence and Behavioral Epidemiology Risk Surveys (SABERS) program and supported the development and implementation of SABERS survey instruments in 18 countries. RTI staff collaborated with the Department of Defense HIV/AIDS Prevention Program and host country military and health care leadership to develop a fully tested, culturally appropriate survey and data collection instrument and build local capacity by identifying and training local interviewers. We summarize the critical steps, challenges faced, and lessons learned from 12 years' experience developing, testing, and implementing SABERS instruments among military populations in Africa, Asia, and the Caribbean.

RESUMO

BACKGROUND: Obstetric hemorrhage (OH) and access to peripartum blood transfusion remains a global health challenge. The rates of peripartum transfusion in South Africa exceed those in high-income countries despite comparable rates of OH. We sought to evaluate factors associated with peripartum transfusion. STUDY DESIGN AND METHODS: A case-control study was conducted at four large South African hospitals. Transfused peripartum women (cases) and nontransfused controls were stratum matched 1:2 by hospital and delivery date. Data on obstetric, transfusion, and human immunodeficiency virus (HIV) history were abstracted from medical records. Blood was obtained for laboratory evaluation. We calculated unadjusted and adjusted odds ratios (ORs) for transfusion using logistic regression. RESULTS: A total of 1200 transfused cases and 2434 controls were evaluated. Antepartum hemorrhage (OR, 197.95; 95% confidence interval [CI], 104.27-375.78), hemorrhage with vaginal delivery (OR, 136.46; 95% CI, 75.87-245.18), prenatal anemia (OR, 22.76; 95% CI, 12.34-41.93 for prenatal hemoglobin level < 7 g/dL), and failed access to prenatal care (OR, 6.71; 95% CI, 4.32-10.42) were the major risk factors for transfusion. Platelet (PLT) count (ORs, 4.10, 2.66, and 1.77 for ≤50 × 109 , 51 × 109 -100 × 109 , and 101 × 109 -150 × 109 cells/L, respectively), HIV infection (OR, 1.29; 95% CI, 1.02-1.62), and admitting hospital (twofold variation) were also associated with transfusion. Mode of delivery, race, age category, gravidity, parity, gestational age, and birthweight were not independently associated with transfusion. CONCLUSION: Major risk factors of peripartum transfusion in South Africa, namely, prenatal anemia and access to prenatal care, may be amenable to intervention. HIV infection and moderately low PLT count are novel risk factors that merit further investigation.

RESUMO

: The current article reviews economic aspects of selected HIV/noncommunicable disease (NCD) service delivery integration programs to assess the efficiency of integration in limited capacity settings. We define economies of scope and scale and their relevance to HIV/NCD integration. We summarize the results of a systematic review of cost and cost-effectiveness studies of integrated care, which identified 12 datasets (nine studies) with a wide range of findings driven by differences in research questions, study methods, and health conditions measured. All studies were done in Africa and examined screening interventions only. No studies assessed the cost of integrated, long-term disease management. Few studies estimated the cost-effectiveness of integrated screening programs. The additional cost of integrating NCD screening with HIV care platforms represented a 6-30% increase in the total costs of the programs for noncancer NCDs, with cervical cancer screening costs dependent on screening strategy. We conducted 11 key informant interviews to uncover perceptions of the economics of HIV/NCD integration. None of the informants had hard information about the economic efficiency of integration. Most expected integrated care to be more cost-effective than current practice, though a minority thought that greater specialization could be more cost-effective. In the final section of this article, we summarize research needs and propose a 'minimum economic dataset' for future studies. We conclude that, although integrated HIV/NCD care has many benefits, the economic justification is unproven. Better information on the cost, cost-effectiveness, and fiscal sustainability of integrated programs is needed to justify this approach in limited-resource countries.

RESUMO

OVERVIEW: After two decades of civil war, South Sudan has limited published data on HIV prevalence and behavioral determinants of HIV infection risk. A surge in HIV/AIDS prevalence is a real concern for this new country with limited access to medical or HIV preventive services, and low education and literacy levels. We present findings from the first bio-behavioral surveillance survey conducted within the Sudan People's Liberation Army (SPLA). METHODS: A cross-sectional survey of 1,149 randomly selected soldiers from thirteen SPLA bases was conducted in two phases: July to August 2010 and April to May 2012. Consenting participants received HIV rapid tests, pre- and post-test counseling, and a personal interview. Demographics, knowledge, attitudes, and behaviors, including sexual behavior, alcohol use, and mental health were assessed using computer-assisted interviews. FINDINGS: The final sample included 1,063 survey participants (96.7% male). Education levels within the SPLA are low; only 16.4% attended school beyond the primary level. The overall HIV prevalence in the sample was 5.0% (95% confidence interval [CI]: 3.6-6.9). High-risk behaviors (e.g., multiple or concurrent sexual partners, heavy alcohol use, low condom use) were noted among SPLA members. High levels of HIV stigma were identified: 90.6% (n = 916) responded with one or more negative beliefs towards PLHIV, and 60.3% thought a healthy-looking person with HIV should not be allowed to remain in the SPLA. CONCLUSION: Results from this first evaluation of risk behaviors and HIV prevalence among the SPLA highlight high-risk behaviors that may contribute to the spread of HIV. Understanding potential comorbid conditions will be critical to designing strategies to reduce HIV risk. This survey represents the first steps in understanding the HIV epidemic within the SPLA context.

RESUMO

This paper uses the National Longitudinal Study of Adolescent Health to investigate the impact of housing instability in adolescence on the likelihood of subsequent graduation from high school. Combining census data, self-reports, and information about respondents' residential changes, we use the variation in households' number of moves and neighborhood quality to predict whether participants obtain a high school diploma. Controlling for major predictors of housing mobility, students experiencing at least one move over a 12-month period have a roughly 50% decreased likelihood of obtaining a high school diploma by the age of 25. These associations are identified regardless of whether students move to a poorer or less-poor neighborhood. Our results carry implications for the development of housing policies and interventions designed for disadvantaged populations.

RESUMO

Monitoring of treatment coverage following mass drug administration is essential to ensure program success. Coverage results reported by drug administrators are often validated by using population surveys. This study evaluates the design of a multistage cluster sample survey conducted in 2007-2008 and implemented at the district level to assess drug coverage in the 4 African countries of Burkina Faso, Ghana, Niger, and Uganda. Estimates of precision of coverage were calculated, and factors contributing to the observed variance were analyzed. Precision of ±5 percentage points was obtained in 39% (n = 12) of cases, and precision of ±10 percentage points was obtained in 77% (n = 24) of cases. The factor having the largest impact on the actual precision obtained in these surveys was the high level of clustering, the impact of which is incorporated in the design effect. Key recommendations are made for the design and analysis of future surveys; guidelines are presented for thinking through the number of clusters that should be selected and how a cluster should be designed.

RESUMO

UNLABELLED: This study sought to examine relationships between depressive symptoms and prenatal smoking and/or household environmental tobacco smoke exposure (HH-ETSE) among urban minority women. We analyzed private, audio computer-assisted self interview data from a clinic-based sample of 929 minority pregnant women in Washington, DC. Depressive symptoms were assessed via the Beck Depression Inventory Fast Screen. HH-ETSE, current smoking, and former smoking were assessed via self-report. Depression levels and demographic characteristics were compared: (1) among nonsmokers, for those reporting HH-ETSE versus no HH-ETSE; and (2) among smokers, for those reporting current smoking (in last 7 days) versus former smokers. Measures associated with HH-ETSE/current smoking in bivariate analysis at P < 0.20 were included in adjusted logistic regression models. HH-ETSE, as a possible indicator of a social smoking network, was assessed as a mediator for the relationship between depression and current smoking. RESULTS: Non-smokers reporting moderate-to-severe depressive symptoms showed significantly higher adjusted odds of prenatal HH-ETSE (AOR 2.5, 95% CI [1.2, 5.2]). Smokers reporting moderate-to-severe or mild depressive symptoms showed significantly higher adjusted odds of current smoking (AOR 1.9, 95% CI [1.1, 3.5] and AOR 1.8, 95% CI [1.1, 3.1], respectively). Among smokers, HH-ETSE was a significant mediator for the association between moderate-to-severe symptoms and current smoking. In conclusion, health care providers should be aware that depressed urban minority women are at risk of continued smoking/HH-ETSE during pregnancy. Interventions designed to encourage behavior change should include screening for depression, and build skills so that women are better able to address the social environment.

RESUMO

Adolescent mothers in Washington, DC have a high rate of subsequent teen pregnancies, often within 24 months. Children of teen mothers are at risk for adverse psychosocial outcomes. When adolescents are strongly attached to parents, schools, and positive peers, they may be less likely to repeat a pregnancy. This study tested the efficacy of a counseling intervention delivered by cell phone and focused on postponing subsequent teen pregnancies by strengthening healthy relationships, reproductive practices, and positive youth assets. The objective of this study was to compare time to a repeat pregnancy between the intervention and usual care groups, and, secondarily, to determine whether treatment intensity influenced time to subsequent conception. Primiparous pregnant teens ages 15-19, were recruited in Washington, DC. Of 849 teens screened, 29.3% (n = 249) met inclusion criteria, consented to participate, and completed baseline measures. They were then randomized to the intervention (N = 124) or to usual care (N = 125). Intervention group teens received cell phones for 18 months of counseling sessions, and quarterly group sessions. Follow-up measures assessed subsequent pregnancy through 24 months post-delivery. A survival analysis compared time to subsequent conception in the two treatment groups. Additional models examined the effect of treatment intensity. By 24 months, 31% of the intervention and 36% of usual care group teens had a subsequent pregnancy. Group differences were not statistically significant in intent-to-treat analysis. Because there was variability in the degree of exposure of teens to the curriculum, a survival analysis accounting for treatment intensity was performed and a significant interaction with age was detected. Participants who were aged 15-17 years at delivery showed a significant reduction in subsequent pregnancy with increased levels of intervention exposure (P < 0.01), but not those ≥ 18 years. Adolescents ≥ 18 years faced considerable challenges to treatment success. Individual, social, and contextual factors are all important to consider in the prevention of repeat teen pregnancy. Cell phone-based approaches to counseling may not be the most ideal for addressing complex, socially-mediated behaviors such as this, except for selective subgroups. A lack of resources within the community for older teens may interfere with program success.
