Scaling Up Antenatal Syphilis Screening in Mozambique: Transforming Policy to Action

A study to better understand under-utilization of laboratory tests for antenatal care in Senegal

OBJECTIVE

To better understand factors contributing to underutilization of laboratory services for health care delivery in sub-Saharan Africa, we conducted a study in Senegalese Antenatal Care clinics (ANC) and laboratories to determine the extent of underutilization, contributing factors, and bottlenecks in the cascade of care from first ANC visit, test uptake, to availability of test results and appropriate clinical management.

METHODS

At 16 health facilities, pregnant women attending for their first ANC visit were consecutively recruited and information was prospectively collected on the request, execution, results and clinical management of seven nationally recommended laboratory screening tests for normal pregnancy: hemoglobin concentration (Hb), syphilis serology, HIV serology, determination of proteinuria (PU), determination of blood group and Rhesus factor, Emmel test to detect sickle cell disease, and glycaemia. Health facility staff were interviewed on human resource capacity, management of the ANC and the laboratory, and availability and use of guidelines.

RESULTS

Of 1246 ANC attendants, 400 (32%) had complete results. Completeness varied between facilities from 0-99%. In multilevel logistic regression analysis of women nested in facilities, complete uptake was lower if women started ANC later in pregnancy; very low in rural ANC attendants who ever delivered compared to urban primigravidae (OR 0.064; 95%CI 0.00-0.52); and higher if the facility routinely recommended all seven tests. In the cascade from test request to clinical management, the most frequent bottleneck was non-execution of requested tests, while unavailability of results for executed test was uncommon (<2%). Overall, of 525 abnormal test results 97(18%) had a record of adequate clinical management.

CONCLUSION

Our study illustrates challenges to test uptake even when laboratory testing capacity is in place, with large differences between facilities, and underscores the importance of management, policy, and the importance of considering local context in order to improve service delivery to expectant mothers.

Factors associated with prenatal care and HIV and syphilis testing during pregnancy in primary health care

OBJECTIVE

To evaluate the factors associated with HIV and syphilis testing during pregnancy in Brazil.

METHODS

This was an ecological study covering all Brazilian municipalities evaluated by the second cycle of the National Program for Access and Quality Improvement in Primary Care, 2013-2014. The dependent variables were based on prenatal care access: prenatal care appointments, and HIV and syphilis tests during prenatal care. The independent variables were compared with demographic and social characteristics. Bivariate analysis was performed assessing the three outcomes with the independent variables. Variables with significant associations in this bivariate analysis were fit in a Poisson multiple regression analysis with robust variance to obtain adjusted estimates.

RESULT

Poisson regression analysis showed a statistically significant association with the variables “less than eight years of study” [prevalence ratio (PR) = 1.31; 95%CI 1.19–1.45; p < 0.001] and “participants of the cash transfer program” (PR = 0.80; 95%CI 0.72–0.88; p < 0.001) for the outcome of “having less than six prenatal care appointments” and individual variables. A statistically significant association was found for “participants of the cash transfer program” (PR = 1.43; 95%CI 1.19–1.72; p < 0.001) regarding the outcome from the comparison between HIV testing absence during prenatal care and demographic and social characteristics. The absence of syphilis testing during prenatal care, and demographic and social characteristics presented a statistically significant association for the education level variable “less than eight years of study” (PR =1.75; 95%CI 1.56–1.96; p < 0.001) and “participants of the cash transfer program” (PR = 1.21, 95%CI 1.07–1.36; p < 0.001).

CONCLUSIONS

The individual factors were associated with prenatal care appointments and HIV and syphilis tests in Brazilian pregnant women. They show missed opportunities for diagnosing HIV and syphilis infection during prenatal care and indicate weaknesses in the quality of maternal health care services to eliminate mother-to-child transmission.

Assessing stakeholder perceptions of the acceptability and feasibility of national scale-up for a dual HIV/syphilis rapid diagnostic test in Malawi

OBJECTIVES

The WHO recommends pregnant women receive both HIV and syphilis testing at their first antenatal care visit, as untreated maternal infections can lead to severe, adverse pregnancy outcomes. One strategy for increasing testing for both HIV and syphilis is the use of point-of-care (rapid) diagnostic tests that are simple, proven effective and inexpensive. In Malawi, pregnant women routinely receive HIV testing, but only 10% are tested for syphilis at their first antenatal care visit. This evaluation explores stakeholder perceptions of a novel, dual HIV/syphilis rapid diagnostic test and potential barriers to national scale-up of the dual test in Malawi.

METHODS

During June and July 2015, we conducted 15 semistructured interviews with 25 healthcare workers, laboratorians, Ministry of Health leaders and partner agency representatives working in prevention of mother-to-child transmission in Malawi. We asked stakeholders about the importance of a dual rapid diagnostic test, concerns using and procuring the dual test and recommendations for national expansion.

RESULTS

Stakeholders viewed the test favourably, citing the importance of a dual rapid test in preventing missed opportunities for syphilis diagnosis and treatment, improving infant outcomes and increasing syphilis testing coverage. Primary technical concerns were about the additional procedural steps needed to perform the test, the possibility that testers may not adhere to required waiting times before interpreting results and difficulty reading and interpreting test results. Stakeholders thought national scale-up would require demonstration of cost-savings, uniform coordination, revisions to testing guidelines and algorithms, training of testers and a reliable supply chain.

CONCLUSIONS

Stakeholders largely support implementation of a dual HIV/syphilis rapid diagnostic test as a feasible alternative to current antenatal testing. Scale-up will require addressing perceived barriers; negotiating changes to existing algorithms and guidelines; and Ministry of Health approval and funding to support training of staff and procurement of supplies.

Rollout of rapid point of care tests for antenatal syphilis screening in Ghana: healthcare provider perspectives and experiences

BACKGROUND

Effective implementation of rapid point of care tests (POCTs) for antenatal syphilis screening especially in settings where antenatal care attendance is high, can significantly increase screening coverage and treatment uptake. The operational challenges of introducing rapid syphilis POCTs at scale needs to be investigated. This study explores healthcare providers' experiences and challenges in antenatal syphilis screening following the national rollout of rapid syphilis POCTs in Ghana.

METHODS

Prior to the main study, we undertook a desk review of key syphilis policy documents, and conducted key stakeholder interviews and a baseline survey of syphilis screening practices. Antenatal syphilis screening had been poorly implemented mainly due to inadequate technical and logistic support, and lack of monitoring and supervision. For the main research, semi-structured interviews were conducted with 51 purposively selected healthcare staff involved in antenatal syphilis screening in 15 health facilities in three regions, representative of all levels of healthcare in Ghana and two regional programme coordinators, at least four months after the rollout. The interviews were supplemented with an audit of the conduct of antenatal care, syphilis-related supplies and other maternal and newborn interventions. Qualitative data were coded and analysed using Nvivo software.

RESULTS

Syphilis screening with rapid POCTs was integrated into antenatal care in almost all (13/15) the facilities surveyed. Testing and treatment were offered free of charge to pregnant women, their partners and babies. In most facilities, midwives were performing syphilis tests together with HIV tests. Operational challenges included: inadequate training and lack of refresher training, lack of clear testing guidelines, clear channels of communication, supervision, and guidance on treatment and referral procedures, frequent stockouts of, or expired test kits, staff overload, and poor documentation of test results and treatment.

CONCLUSION

Although syphilis screening with rapid syphilis POCTs was integrated into antenatal care, key challenges, particularly around supply chain and supervision, need to be addressed to improve and sustain such a programme.

Determinants of stillbirths occurred in health facilities in Zambezia province, Mozambique (2013-2014)

Abstract Objectives: to identify the determinants of stillbirths in Zambezia province, Mozambique. Methods: a retrospective cross-sectional ecological study was carried out in 2013-2014 by using perinatal indicators captured by the health information system in Zambezia. Sequentially perinatal care indicators, bivariate analysis and multiple adjusted regression at a 5% significance level with possible explainable variables of stillbirths were described. Results: a median proportion of stillbirths was 1.6%, low birth weight and preterm birth and obstetric complications were 4.9%, 1.9% and 4.1%, respectively. The bivariate analysis demonstrated association of stillbirths with anemia (p=0.043), antepartum hemorrhage (p=0.009), dystocic delivery (p<0.001), obstructed labor (p=0.004). In the analysis of multiple adjusted regression, the obstructed labor were a predictor (ß=0.435; p=0.03) to stillbirths Conclusions: the most important factor associated to stillbirths in health facilities in Zambezia province in 2013-2014 was the obstructed labor. The strengthening of diagnostic analysis and the attempt to handle obstetric complications is still a priority in Zambezia, in being able to decrease the avoidable perinatal deaths.

Promoting development and uptake of health innovations: The Nose to Tail Tool

Introduction

Health sector management is increasingly complex as new health technologies, treatments, and innovative service delivery strategies are developed. Many of these innovations are implemented prematurely, or fail to be implemented at scale, resulting in substantial wasted resources.  

Methods

A scoping review was conducted to identify articles that described the scale up process conceptually or that described an instance in which a healthcare innovation was scaled up. We define scale up as the expansion and extension of delivery or access to an innovation for all end users in a jurisdiction who will benefit from it.

Results

Sixty nine articles were eligible for review. Frequently described stages in the innovation process and contextual issues that influence progress through each stage were mapped. 16 stages were identified: 12 deliberation and 4 action stages. Included papers suggest that innovations progress through stages of maturity and the uptake of innovation depends on the innovation aligning with the interests of 3 critical stakeholder groups (innovators, end users and the decision makers) and is also influenced by 3 broader contexts (social and physical environment, the health system, and the regulatory, political and economic environment). The 16 stages form the rows of the Nose to Tail Tool (NTT) grid and the 6 contingency factors form columns. The resulting stage-by-issue grid consists of 72 cells, each populated with cell-specific questions, prompts and considerations from the reviewed literature.

Conclusion

We offer a tool that helps stakeholders identify the stage of maturity of their innovation, helps facilitate deliberative discussions on the key considerations for each major stakeholder group and the major contextual barriers that the innovation faces. We believe the NTT will help to identify potential problems that the innovation will face and facilitates early modification, before large investments are made in a potentially flawed solution.

Introduction of rapid syphilis testing in antenatal care: A systematic review of the impact on HIV and syphilis testing uptake and coverage

BACKGROUND

Global guidelines recommend universal syphilis and HIV screening for pregnant women. Rapid syphilis testing (RST) may contribute toward achievement of universal screening.

OBJECTIVES

To examine the impact of RST on syphilis and HIV screening among pregnant women.

SEARCH STRATEGY

We searched MEDLINE for English- and non-English language articles published through November, 2014.

SELECTION CRITERIA

We included studies that used a comparative design and reported on syphilis and HIV test uptake among pregnant women in low- and middle-income countries (LMICs) following introduction of RST.

DATA COLLECTION AND ANALYSIS

Data were extracted from six eligible articles presenting findings from Asia, Africa, and Latin America.

MAIN RESULTS

All studies reported substantial increases in antenatal syphilis testing following introduction of RST; the latter did not appear to adversely impact antenatal HIV screening levels at sites already offering rapid HIV testing and may increase HIV screening among pregnant women in some settings. Qualitative data revealed that women were highly satisfied with RST. Nevertheless, ensuring adequate training for healthcare workers and supplies of commodities were cited as key implementation barriers.

CONCLUSIONS

RST may increase antenatal syphilis and HIV screening and contribute to the improvement of antenatal care in LMICs.

Introduction of Syphilis Point-of-Care Tests, from Pilot Study to National Programme Implementation in Zambia: A Qualitative Study of Healthcare Workers' Perspectives on Testing, Training and Quality Assurance

Syphilis affects 1.4 million pregnant women globally each year. Maternal syphilis causes congenital syphilis in over half of affected pregnancies, leading to early foetal loss, pregnancy complications, stillbirth and neonatal death. Syphilis is under-diagnosed in pregnant women. Point-of-care rapid syphilis tests (RST) allow for same-day treatment and address logistical barriers to testing encountered with standard Rapid Plasma Reagin testing. Recent literature emphasises successful introduction of new health technologies requires healthcare worker (HCW) acceptance, effective training, quality monitoring and robust health systems. Following a successful pilot, the Zambian Ministry of Health (MoH) adopted RST into policy, integrating them into prevention of mother-to-child transmission of HIV clinics in four underserved Zambian districts. We compare HCW experiences, including challenges encountered in scaling up from a highly supported NGO-led pilot to a large-scale MoH-led national programme. Questionnaires were administered through structured interviews of 16 HCWs in two pilot districts and 24 HCWs in two different rollout districts. Supplementary data were gathered via stakeholder interviews, clinic registers and supervisory visits. Using a conceptual framework adapted from health technology literature, we explored RST acceptance and usability. Quantitative data were analysed using descriptive statistics. Key themes in qualitative data were explored using template analysis. Overall, HCWs accepted RST as learnable, suitable, effective tools to improve antenatal services, which were usable in diverse clinical settings. Changes in training, supervision and quality monitoring models between pilot and rollout may have influenced rollout HCW acceptance and compromised testing quality. While quality monitoring was integrated into national policy and training, implementation was limited during rollout despite financial support and mentorship. We illustrate that new health technology pilot research can rapidly translate into policy change and scale-up. However, training, supervision and quality assurance models should be reviewed and strengthened as rollout of the Zambian RST programme continues.

Estimating the uptake of maternal syphilis screening and other antenatal interventions before and after national rollout of syphilis point-of-care testing in Ghana

OBJECTIVE

To compare the uptake of maternal syphilis and HIV screening, intermittent preventive treatment for malaria, and tetanus toxoid administration in three regions of Ghana, before and after the rollout of syphilis point-of-care tests (POCTs).

METHODS

Antenatal register records were reviewed in 15 selected health facilities over an eight-month period, 16 months apart. Register records had been evaluated using the maternal record booklets as a gold standard in a separate prior survey.

RESULTS

In the evaluation study, the sensitivity of register data was low, ranging from 33.3% for tetanus toxoid administration to 53.8% for syphilis serology. In total, 8282 antenatal client records (4141 in each period) were reviewed. Less than a third of pregnant women received any single intervention at either period (ranging from 17.8% for tetanus toxoid to 29.8% for HIV testing). Overall, HIV screening had a marginal absolute increase of about 2% while the remaining interventions experienced non-significant absolute decreases of 4.1 to 11.1%. When adjusting for under-recording, syphilis screening uptake was 50% before and 33.6% after the introduction of POCTs.

CONCLUSION

Use of POCTs for syphilis did not result in increased uptake. Routine monitoring of antenatal interventions using the antenatal register may result in underestimation of their uptake.

Incidence of HIV and the prevalence of HIV, hepatitis B and syphilis among youths in Maputo, Mozambique: a cohort study

Background

Prevalence of HIV in Mozambique among individuals aged 15–49 years is 11.5%. The HIV prevalence is higher in women than in men across the country, peaking at ages 25–29 years and 35–39 years, respectively. In this study, we aimed at determining the prevalence and incidence of HIV, prevalence of Hepatitis B (HBV), and prevalence of syphilis in youths. We also characterized a cohort of youths for future participation in phase I/II HIV vaccine trials.

Methods

The study was conducted at a youth clinic in Maputo Central Hospital from August 2009 to October 2011. Youths of both genders aged 18–24 years (n = 1380) were screened for HIV using a sequential algorithm of two immunochromatographic assays, HBV using an enzyme linked immunosorbant test, and syphilis using a treponemal immunochromatographic strip test. The HIV seronegative participants (n = 1309) were followed-up for 12 months with quarterly study visits. The clinical and behavioral data were collected using structured questionnaires. The HIV seroconversions were confirmed by a molecular assay.

Results

The study population was female dominant (76.8%). All participants had a formal education, with 44.6% studying for technical or higher education degrees. The mean age at sexual debut was 16.6 years (SD: ±1.74), with 85.6% reporting more than one sexual partner in life. The screening showed the prevalence of HIV, HBV, and syphilis at 5.1% (95% CI: 3.97–6.31), 12.2% (95% CI 10.5%–14.0%), and 0.36% (95% CI 0.15%–0.84%), respectively. The HIV incidence rate was found to be 1.14/100 person years (95% CI: 0.67–1.92). Retention rates were stable throughout the study being 85.1% at the last visit.

Conclusion

Incidence of HIV in this cohort of youths in Maputo was relatively low. Also, the prevalence of HIV and syphilis was lower than the national values in this age group. However, the HBV prevalence was higher than in previous reports in the country.

Factors associated with failure to screen for syphilis during antenatal care in Ghana: a case control study

Background

There is little data regarding the effect of ramping up new screening interventions on their uptake by target populations into routine care services in developing countries. This study aimed to determine patient-level factors associated with failure of pregnant women to get screened for syphilis during antenatal care, in the context of a national rollout of rapid syphilis point of care tests (POCTs) in Ghana.

Methods

An unmatched 1:2 case control study conducted among women admitted for delivery in two district hospitals in the Ashanti Region of Ghana from August to October 2010, 7 to 9 months after the introduction of POCTs in the region. Cases were women who had not been screened for syphilis during antenatal care and controls were women who had been screened. Patient-reported factors for being unscreened were examined using logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (CIs).

Results

160 consecutive unscreened and 327 screened women were recruited. Most women had good knowledge of syphilis (58.7% among unscreened women vs. 64.2% among screened; P = 0.24). Factors associated with failure to get screened were: attending antenatal care in a private health facility (adjusted OR, 11.09; 95% CI 5.48-22.48), previous adverse pregnancy outcome (adjusted OR, 1.98; 95% CI 1.22-3.23) and not being screened for HIV during the current pregnancy (adjusted OR, 2.78; 95% CI 1.50-5.13). The odds of being unscreened also increased with decreasing doses of intermittent preventive treatment for malaria in pregnancy received (P trend < 0.001) and decreasing education level (P trend = 0.02).

Conclusion

Significant risk factors for not being screened, following the national rollout of syphilis POCTs, related to the type of health facility where antenatal care was received and some of the women’s personal characteristics. Targeting of private medical facilities to include syphilis POCTs and support other neglected public health interventions should be a priority.

Integration of antenatal syphilis screening in an urban HIV clinic: a feasibility study

BACKGROUND

Syphilis infection during pregnancy leads to avoidable morbidity and mortality and remains a significant problem in sub-Saharan Africa. Despite global initiatives to increase the proportion of pregnant women screened, implementation has been slow. We sought to investigate the feasibility of adding syphilis screening within an integrated antenatal HIV clinic.

METHODS

Pregnant women attending the HIV antenatal clinic were sequentially enrolled and consenting participants answered a questionnaire on sexual behavior and previous pregnancies, provided sociodemographic data, and were tested using rapid plasmin reagin (RPR). If positive, participants were treated with benzathine penicillin. All were given a partner notification slip and were followed up after delivery to determine birth outcomes.

RESULTS

584 of 606 (95.7%) women approached and consented to test for syphilis. 570 women were enrolled (median age 29 (IQR 25-32) with a median (IQR) CD4 of 372 (257-569) cells/μL). Of the 5.1% (29/570) with a positive RPR, all were asymptomatic, were successfully contacted, and treated with benzathine penicillin without adverse reactions. Overall, 61 (12.1%) of the participants had an adverse birth outcome. In the bivariate analysis, only age was significantly different between those with and without a positive RPR (RR = 1.15, 95% CI 1.065-1.248; p < 0.001). Partners of only 10 (34.5%) participants returned for treatment.

CONCLUSIONS

Structural interventions such as opt-out testing for syphilis within integrated HIV-antenatal care clinics are feasible and capitalize on the excellent care programs that have already been established for HIV care. Novel approaches are required for partner notification.

Integration of preventing mother-to-child transmission of HIV and syphilis testing and treatment in antenatal care services in the Northern Cape and Gauteng provinces, South Africa

BACKGROUND

South Africa recommends universal syphilis and HIV testing in pregnancy, with prompt antiretroviral therapy or penicillin treatment for women testing positive.

METHODS

We used a multistage, purposeful sampling strategy to retrospectively identify clinical records from a sample (7.3%) of 32,518 women delivering from January 2005 to June 2006 at 6 public clinics in the Northern Cape and Gauteng. Descriptive analyses and logistic regression were used to assess coverage and factors related to testing and treatment of HIV and syphilis.

RESULTS

Of 2379 women sampled, 93% accessed antenatal care (ANC) services during pregnancy and 71% before the third pregnancy trimester. Testing during pregnancy or delivery was 74% for HIV and 84% for syphilis; testing at the first ANC visit was 41% and 71%; and infection prevalence at delivery was 14% and 5%, respectively. Of 243 women with reactive HIV tests, 104 (43%) had treatment documented (single-dose nevirapine) before delivery. Of 98 women with reactive syphilis tests, 73% had documented receipt of 1 penicillin injection and 36% had all 3 recommended injections. Multivariable analysis found women tested for syphilis were almost 4 times more likely to have had no HIV test compared with those without syphilis testing (adjusted odds ratios, 3.9; 95% confidence interval, 1.7-5.5).

CONCLUSIONS

Integration and provision of a package of HIV and syphilis testing at the first ANC visit and decentralizing treatments of both infections to primary care settings could increase the coverage of testing and treatment services, thus enhancing the effectiveness of current programs eliminating mother-to-child transmission of HIV and syphilis.

Barriers to antenatal syphilis screening in Burkina Faso

INTRODUCTION

Despite advances in treatment and management, syphilis remains a major public health problem in Burkina Faso. Syphilis in pregnancy poses major health risks for the mother and the fetus and also increases the risk for HIV transmission. Despite its potential benefits, antenatal syphilis screening is often poorly implemented in many sub-Saharan African countries. The purpose of the study is to identify and understand barriers affecting health system performance for syphilis screening among pregnant women in Burkina Faso.

METHODS

We conducted in-depth interviews and observations in the Kaya health district, Burkina Faso. Participants were purposively selected to capture a range of perspectives across different actors with different roles and responsibilities. Seventy-five interviews were conducted with health providers, district managers, facility managers, traditional healers, pregnant women, community health workers, and Non-Governmental Organizations (NGO) managers. Interviews were transcribed and organized into codes and categories using NVivo software.

RESULTS

Participants identified multiple barriers at health providers and community levels. Key barriers at provider level included fragmentation of services, poor communication, low motivation for prescription, and low awareness of syphilis burden. Cost of testing, distance to laboratory and lack of knowledge about syphilis were identified as barriers at community level.

CONCLUSION

The study highlights barriers such as distance, cost of testing, and knowledge about syphilis. The introduction of point of care testing for syphilis could be an entry point for improving coverage of antenatal syphilis screening.

What are the barriers to scaling up health interventions in low and middle income countries? A qualitative study of academic leaders in implementation science

BACKGROUND

Most low and middle income countries (LMICs) are currently not on track to reach the health-related Millennium Development Goals (MDGs). One way to accelerate progress would be through the large-scale implementation of evidence-based health tools and interventions. This study aimed to: (a) explore the barriers that have impeded such scale-up in LMICs, and (b) lay out an "implementation research agenda"--a series of key research questions that need to be addressed in order to help overcome such barriers.

METHODS

Interviews were conducted with fourteen key informants, all of whom are academic leaders in the field of implementation science, who were purposively selected for their expertise in scaling up in LMICs. Interviews were transcribed by hand and manually coded to look for emerging themes related to the two study aims. Barriers to scaling up, and unanswered research questions, were organized into six categories, representing different components of the scaling up process: attributes of the intervention; attributes of the implementers; scale-up approach; attributes of the adopting community; socio-political, fiscal, and cultural context; and research context.

RESULTS

Factors impeding the success of scale-up that emerged from the key informant interviews, and which are areas for future investigation, include: complexity of the intervention and lack of technical consensus; limited human resource, leadership, management, and health systems capacity; poor application of proven diffusion techniques; lack of engagement of local implementers and of the adopting community; and inadequate integration of research into scale-up efforts.

CONCLUSIONS

Key steps in expanding the evidence base on implementation in LMICs include studying how to: simplify interventions; train "scale-up leaders" and health workers dedicated to scale-up; reach and engage communities; match the best delivery strategy to the specific health problem and context; and raise the low profile of implementation science.

Syphilis test availability and uptake at medical facilities in southern China

OBJECTIVE

To examine syphilis testing capacity, screening coverage rates and types of syphilis tests used in medical facilities in southern China.

METHODS

Eleven of the 14 municipalities in Guangdong province participated. Data on syphilis testing capacity, screening coverage and types of syphilis tests used were collected from all types of public medical facilities offering prenatal care (n = 109). A total of 494 680 women who delivered during 2004-2008 were studied.

FINDINGS

In 2008, 54 196 pregnant women (43.1%) were not screened for syphilis. Among such women, 32 863 (60.6%) attended clinics without any syphilis testing capacity and 21 333 (39.4%) attended clinics that performed testing but were not screened. The likelihood of not having syphilis test capacity was much higher for hygiene stations (odds ratio, OR: 10; 95% confidence interval, CI: 4-25), services at the township level (OR: 33; 95% CI: 10-100) and services with ≤ 1000 deliveries per year (OR: 1.002; 95% CI: 1.001-1.003). These same service characteristics correlated with lower screening coverage rates (P < 0.01). Only one antenatal clinic had the capacity to conduct both treponemal and non-treponemal tests for diagnosing syphilis.

CONCLUSION

Syphilis screening is available in very few of the basic medical facilities offering prenatal care where most neonates in southern China are delivered. In light of this and of the increasing incidence of syphilis in the area, expanding point-of-care rapid syphilis testing is a priority.

Integrating prevention of mother-to-child HIV transmission (PMTCT) programmes with other health services for preventing HIV infection and improving HIV outcomes in developing countries

BACKGROUND

Every year nearly 400,000 children are infected with HIV through mother-to-child transmission (MTCT), which is responsible for more than 90% of HIV infections in children. In high-income countries, the MTCT rate is less than 1% through perinatal prevention of mother-to-child HIV transmission (PMTCT) interventions. In low- and middle-income countries, PMTCT programme coverage remains low and consequently transmission rate high. The World Health Organisation recommends integration of PMTCT programmes with other healthcare services to increase access and improve uptake of these interventions.

OBJECTIVES

To assess the effect of integration of perinatal PMTCT measures with other health care services on coverage and service uptake compared to stand-alone PMTCT programmes and healthcare services or partially integrated PMTCT interventions.

SEARCH STRATEGY

We searched the following databases, for the time period of January 1990 to August 2010: MEDLINE, EMBASE, the WHO Global Health Library, CAB abstracts, CINAHL, POPLINE, PsycINFO, Sociological Abstracts, ERIC, AEGIS, Google Scholar, New York Academy of Medicine Grey Literature, Open SIGLE, British Library Catalogue, ProQuest Dissertation & Theses Database and U.S. National Library of Medicine Gateway system. We also searched the Cochrane Database of Systematic Reviews (the Cochrane Library 2010, Issue 7), the Cochrane Central Register of Controlled Trials (the Cochrane Library 2010, Issue 7), Database of Abstracts of Reviews on Effects (the Cochrane Library 2010, Issue 7). We also searched for ongoing trials in the WHO International Clinical Trials Registry and Controlled clinical trials (January 1990 to July 2010). We performed ISI Web of Knowledge Cited Reference Search and scanned the reference lists of the included articles for additional relevant studies. We contacted authors to locate additional eligible studies. To maximise sensitivity we did not employ any methodological filters.

SELECTION CRITERIA

Randomised controlled trials (RCT), cluster-randomised controlled trials (cluster RCT), controlled clinical trials (CCT), controlled before and after (CBA) studies and interrupted time series (ITS) studies comparing integrated PMTCT interventions to non-integrated or partially integrated care for pregnant women, mothers and their infants in low- and middle-income countries.

DATA COLLECTION AND ANALYSIS

Two review authors independently ran the searches, selected studies, assessed methodological quality, and extracted data. The third review author resolved any disagreements.

MAIN RESULTS

Only one study met the inclusion criteria. A cluster-randomised trial (12 clusters, n=7664), compared mother-infant nevirapine coverage at labour ward between intervention clinics implementing rapid HIV testing with structured nevirapine assessment and control clinics implementing informal assessment of nevirapine adherence. The authors measured nevirapine coverage in all clinics at baseline and after the implementation of the intervention. An increase of 10% (range of difference in coverage from -10% to +33%) was observed in the intervention sites compared to 10% decline in mother-infant coverage in the control sites (range of difference in coverage from -13% to 0%). The study showed that the probability of nevirapine coverage of mothers and their infants in the intervention arm compared to control arm increased from 0.89 at baseline to 1.22 during the intervention period, representing a multiplicative effect of 1.37 upon the ratio of relative risks at baseline (RR 1.37, bootstrapped 95% CI, 1.041.77). The study had a low risk of bias. No studies were found that evaluated the effectiveness of integrating other perinatal PMTCT interventions with healthcare services.

AUTHORS' CONCLUSIONS

We found only one study suggesting that integrating perinatal PMTCT interventions with other healthcare services in low- and middle-income countries increases the proportion of pregnant women, mothers and infants receiving PMTCT intervention. The weak evidence base does not enable making any inferences for other countries or contexts. The study that met the inclusion criteria assessed only the impact of integrating PMTCT intervention in labour ward on the proportion of mothers and their infants receiving nevirapine. The study showed significant improvement in intervention coverage but it only addressed the labour ward aspect of PMTCT programme. We did not find sufficient evidence to make definitive conclusions about the effectiveness of integration of these interventions with other health services rather than providing them as stand-alone services. Further research is urgently needed to assess the effect of integrating perinatal prevention of mother-to-child HIV transmission interventions with other health services on intervention coverage, service uptake, quality of care and health outcomes and the optimal integration modality.

Lives Saved Tool supplement detection and treatment of syphilis in pregnancy to reduce syphilis related stillbirths and neonatal mortality

BACKGROUND

Globally syphilis is an important yet preventable cause of stillbirth, neonatal mortality and morbidity.

OBJECTIVES

This review sought to estimate the effect of detection and treatment of active syphilis in pregnancy with at least 2.4 MU benzathine penicillin (or equivalent) on syphilis-related stillbirths and neonatal mortality.

METHODS

We conducted a systematic literature review of multiple databases to identify relevant studies. Data were abstracted into standardised tables and the quality of evidence was assessed using adapted GRADE criteria. Where appropriate, meta-analyses were undertaken.

RESULTS

Moderate quality evidence (3 studies) supports a reduction in the incidence of clinical congenital syphilis of 97% (95% c.i 93 - 98%) with detection and treatment of women with active syphilis in pregnancy with at least 2.4 MU penicillin. The results of meta-analyses suggest that treatment with penicillin is associated with an 82% reduction in stillbirth (95% c.i. 67 - 90%) (8 studies), a 64% reduction in preterm delivery (95% c.i. 53 - 73%) (7 studies) and an 80% reduction in neonatal deaths (95% c.i. 68 - 87%) (5 studies). Although these effect estimates were large and remarkably consistent across studies, few of the studies adjusted for potential confounding factors and thus the overall quality of the evidence was considered low. However, given these large observed effects and a clear biological mechanism for effectiveness the GRADE recommendation is strong.

CONCLUSION

Detection and appropriate, timely penicillin treatment is a highly effective intervention to reduce adverse syphilis-related pregnancy outcomes. More research is required to identify the most cost-effective strategies for achieving maximum coverage of screening for all pregnant women, and access to treatment if required.

A road map for the global elimination of congenital syphilis

Congenital syphilis is the oldest recognized congenital infection, and continues to account for extensive global perinatal morbidity and mortality today. Serious adverse pregnancy outcomes caused by maternal syphilis infection are prevented with screening early in pregnancy and prompt treatment of women testing positive. Intramuscular penicillin, an inexpensive antibiotic on the essential medicine list of nations all over the world, effectively cures infection and prevents congenital syphilis. In fact, at a cost of $11-15 per disability adjusted life year (DALY) averted, maternal syphilis screening and treatment is among the most cost-effective public health interventions in existence. Yet implementation of this basic public health intervention is sporadic in countries with highest congenital syphilis burden. We discuss the global burden of this devastating disease, current progress and ongoing challenges for its elimination in countries with highest prevalence, and next steps in ensuring a world free of preventable perinatal deaths caused by syphilis.

Congenital syphilis: still a serious, under-diagnosed threat for children in resource-poor countries

BACKGROUND

With 700,000 to 1.5 million new cases annually, congenital syphilis remains a major infectious cause of morbidity and mortality in neonates, infants and children in resource-poor countries. We therefore analyzed the extent of congenital syphilis in the pediatric patient population at our rural hospital in Tanzania.

METHODS

For this retrospective analysis, from January 1, 1998 to August 31, 2000, all cases of congenital syphilis were collected from the medical records of the neonatal and pediatric department at Haydom Lutheran Hospital in rural northern Tanzania. Age, sex, weight, clinical signs and symptoms, venereal disease research laboratory (VDRL) results of mother and/or child, hemoglobin concentration, treatment, and outcome were recorded and analyzed.

RESULTS

Fourteen neonates and infants were included. The earlier the diagnosis, the more it rested on maternal data because the presentation of neonatal congenital syphilis resembled neonatal sepsis. Syphilitic skin lesions were only seen in the post-neonatal age group. VDRL results were positive in 11 of the 14 mothers, and in 4 of the infants. Anemia was common in older infants. No patient showed signs of central nervous system involvement. Two patients died, and the remaining were cured after standard treatment with procaine penicillin.

CONCLUSIONS

Highlighting the variable picture of congenital syphilis, this report demonstrates how difficult it is to make a correct diagnosis by solely history and clinical presentation in a resource-poor setting. Hence false-positive and false-negative diagnoses are common, and clinicians have to maintain a high index of suspicion in diagnosing congenital syphilis. Therefore, an important approach to control and finally eliminate congenital syphilis as a major public health problem will be universal on-site syphilis screening of all pregnant women at their first antenatal visit and immediate treatment for those who test positive.

A Safe Motherhood project in Kenya: assessment of antenatal attendance, service provision and implications for PMTCT

OBJECTIVES

To investigate uptake and provision of antenatal care (ANC) services in the Uzazi Bora project: a demonstration-intervention project for Safe Motherhood and prevention of mother-to-child transmission of HIV in Kenya.

METHODS

Data were extracted from antenatal clinic, laboratory and maternity ward registers of all pregnant women attending ANC from January 2004 until September 2006 at three antenatal clinics in Mombasa and two in rural Kwale district of Coast Province, Kenya (n = 25 364). Multiple logistic and proportional odds logistic regression analyses assessed changes over time, and determinants of the frequency and timing of ANC visits, uptake of HIV testing, and provision of iron sulphate, folate and single-dose nevirapine (sd-NVP).

RESULTS

About half of women in rural and urban settings (52.2% and 49.2%, respectively) attended antenatal clinics only once. Lower parity, urban setting, older age and having received iron sulphate and folate supplements during the first ANC visit were independent predictors of more frequent visits. The first ANC visit occurred after 28 weeks of pregnancy for 30% (5894/19 432) of women. By mid-2006, provision of nevirapine to HIV-positive women had increased from 32.5% and 11.7% in rural and urban clinics, to 67.0% and 74.6%, respectively. Equally marked improvements were observed in the uptake of HIV testing and the provision of iron sulphate and folate.

CONCLUSION

Provision of ANC services, including sd-NVP, increased markedly over time. While further improvements in quality are necessary, particular attention is needed to implement evidence-based interventions to alter ANC utilization patterns. Encouragingly, improved provision of basic essential obstetric care may increase attendance.

Global report on preterm birth and stillbirth (4 of 7): delivery of interventions

BACKGROUND

The efficacious interventions identified in the previous article of this report will fail unless they are delivered at high and equitable coverage. This article discusses critical delivery constraints and strategies.

BARRIERS TO SCALING UP INTERVENTIONS

Achieving universal coverage entails addressing major barriers at many levels. An overarching constraint is the lack of political will, resulting from the dearth of preterm birth and stillbirth data and the lack of visibility. Other barriers exist at the household and community levels, such as insufficient demand for interventions or sociocultural barriers; at the health services level, such as a lack of resources and trained healthcare providers; and at the health sector policy and management level, such as poorly functioning, centralized systems. Additional constraints involve weak governance and accountability, political instability, and challenges in the physical environment.

STRATEGIES AND EXAMPLES

Scaling up maternal, newborn and child health interventions requires strengthening health systems, but there is also a role for focused, targeted interventions. Choosing a strategy involves identifying appropriate channels for reaching high coverage, which depends on many factors such as access to and attendance at healthcare facilities. Delivery channels vary, and may include facility- and community-based healthcare providers, mass media campaigns, and community-based approaches and marketing strategies. Issues related to scaling up are discussed in the context of four interventions that may be given to mothers at different stages throughout pregnancy or to newborns: (1) detection and treatment of syphilis; (2) emergency Cesarean section; (3) newborn resuscitation; and (4) kangaroo mother care. Systematic reviews of the literature and large-scale implementation studies are analyzed for each intervention.

CONCLUSION

Equitable and successful scale-up of preterm birth and stillbirth interventions will require addressing multiple barriers, and utilizing multiple delivery approaches and channels. Another important need is developing strategies to discontinue ineffective or harmful interventions. Preterm birth and stillbirth interventions must also be placed in the broader maternal, newborn and child health context to identify and prioritize those that will help improve several outcomes at the same time. The next article discusses advocacy challenges and opportunities.

Scaling up in international health: what are the key issues?

The term 'scaling up' is now widely used in the international health literature, though it lacks an agreed definition. We review what is meant by scaling up in the context of changes in international health and development over the last decade. We argue that the notion of scaling up is primarily used to describe the ambition or process of expanding the coverage of health interventions, though the term has also referred to increasing the financial, human and capital resources required to expand coverage. We discuss four pertinent issues in scaling up the coverage of health interventions: the costs of scaling up coverage; constraints to scaling up; equity and quality concerns; and key service delivery issues when scaling up. We then review recent progress in scaling up the coverage of health interventions. This includes a considerable increase in the volume of aid, accompanied by numerous new health initiatives and financing mechanisms. There have also been improvements in health outcomes and some examples of successful large-scale programmes. Finally, we reflect on the importance of obtaining a better understanding of how to deliver priority health interventions at scale, the current emphasis on health system strengthening and the challenges of sustaining scaling up in the prevailing global economic environment.

Do targeted HIV programs improve overall care for pregnant women?: Antenatal syphilis management in Zambia before and after implementation of prevention of mother-to-child HIV transmission programs

BACKGROUND

The implementation of disease-specific research or service programs may have an ancillary beneficial or harmful impact on routine clinical services.

METHODS

We reviewed the records of 5801 first visits to 22 antenatal clinics from 1997 to 2004 in Lusaka, Zambia and examined documented syphilis rapid plasma reagin (RPR) screening and syphilis treatment before and after implementation of research and/or service programs in prevention of mother-to-child (PMTCT) HIV transmission.

FINDINGS

Compared with before PMTCT program implementation, the prevalence odds ratios (PORs) and 95% confidence intervals (CIs) for documented RPR screening were 0.9 (0.7 to 1.1) after implementation of research, 0.7 (0.6 to 0.8) after service, and 2.5 (2.1 to 3.0) after research and service programs.

CONCLUSIONS

Documented RPR screening was improved after implementation of PMTCT research and service were operating simultaneously and not with research or service alone. Health policy makers and researchers should plan explicitly for how the targeted HIV programs, service, and/or research can have a broader primary care impact.

Antibiotics for syphilis diagnosed during pregnancy

BACKGROUND

Congenital syphilis is an increasing problem in many developing countries and in the transitional economies of Eastern Europe and the former Soviet Union. In several countries this increase has been aggravated by HIV/AIDS. While the effectiveness of penicillin in the treatment of syphilis in pregnant women and the prevention of congenital syphilis was established shortly after the introduction of penicillin in the 1940s, there is uncertainty about the optimal treatment regimens.

OBJECTIVES

To identify the most effective antibiotic treatment regimen (in terms of dose, length of course and mode of administration) of syphilis with and without concomitant infection with HIV for pregnant women infected with syphilis.

SEARCH STRATEGY

MEDLINE 1966 to March 2000; EMBASE 1974 to March 2000, the Cochrane Controlled Trials Register (last searched March 2001), the Cochrane Pregnancy and Childbirth group trials register (last searched March 2001) and the references of traditional reviews were searched. Experts in specialist units were contacted.

SELECTION CRITERIA

It was planned that any trial in which an attempt is made to allocate treatment for syphilis during pregnancy by a random or quasi-random method would be included in this review.

DATA COLLECTION AND ANALYSIS

Information was extracted using a data extraction sheet and this included entry criteria, the source of controls, and whether the authors stratified by the stage of pregnancy when the diagnosis of syphilis was made.

MAIN RESULTS

Twenty six studies met the criteria for detailed scrutiny. However, none of these met the pre-determined criteria for comparative groups and none included comparisons between randomly allocated groups of pregnant women.

REVIEWER'S CONCLUSIONS

While there is no doubt that penicillin is effective in the treatment of syphilis in pregnancy and the prevention of congenital syphilis, uncertainty remains about what are the optimal treatment regimens. Further studies are needed to evaluate treatment failure cases with currently recommended regimens and this should include an assessment of the role of HIV infection in cases of prenatal syphilis treatment failure. The effectiveness of various antibiotic regimens for the treatment of primary and secondary syphilis in pregnant women need to be assessed using randomised controlled trials which compare them with existing recommendations.
