Patterns and Predictors of Incident Return to HIV Care Among Traced, Disengaged Patients in Zambia: Analysis of a Prospective Cohort.

Dynamic movement of patients in and out of HIV care is prevalent, but there is limited information on patterns of patient re-engagement or predictors of return to guide HIV programs to better support patient engagement. From a probability-based sample of lost to follow-up, adult patients traced by peer educators from 31 Zambian health facilities, we prospectively followed disengaged HIV patients for return clinic visits. We estimated the cumulative incidence of return and the time to return using Kaplan-Meier methods. We used univariate and multivariable Cox proportional hazards regression to conduct a risk factor analysis identifying predictors of incident return across a social ecological framework. Of the 556 disengaged patients, 73.0% [95% confidence interval (CI): 61.0 to 83.8] returned to HIV care. The median follow-up time from disengagement was 32.3 months (interquartile range: 23.6-38.9). The rate of return decreased with time postdisengagement. Independent predictors of incident return included a previous gap in care [adjusted Hazard Ratio (aHR): 1.95, 95% CI: 1.23 to 3.09] and confronting a stigmatizer once in the past year (aHR: 2.14, 95% CI: 1.25 to 3.65). Compared with a rural facility, patients were less likely to return if they sought care from an urban facility (aHR: 0.68, 95% CI: 0.48 to 0.96) or hospital (aHR: 0.52, 95% CI: 0.33 to 0.82). Interventions are needed to hasten re-engagement in HIV care. Early and differential interventions by time since disengagement may improve intervention effectiveness. Patients in urban and tertiary care settings may need additional support. Improving patient resilience, outreach after a care gap, and community stigma reduction may facilitate return. Future re-engagement research should include causal evaluation of identified factors.

Cost-effectiveness of integrated HIV prevention and family planning services for Zambian couples.

To present the incremental cost from the payer's perspective and effectiveness of couples' family planning counseling (CFPC) with long-acting reversible contraception (LARC) access integrated with couples' voluntary HIV counseling and testing (CVCT) in Zambia. This integrated program is evaluated incremental to existing individual HIV counseling and testing and family planning services. Implementation and modelling. Fifty-five government health facilities in Zambia. Patients in government health facilities. Community health workers and personnel promoted and delivered integrated CVCT+CFPC from March 2013 to September 2015. We report financial costs of actual expenditures during integrated program implementation and outcomes of CVCT+CFPC uptake and LARC uptake. We model primary outcomes of cost-per-: adult HIV infections averted by CVCT, unintended pregnancies averted by LARC, couple-years of protection against unintended pregnancy by LARC, and perinatal HIV infections averted by LARC. Costs and outcomes were discounted at 3% per year. Integrated program costs were $3 582 186 (2015 USD), 82 231 couples received CVCT+CFPC, and 56 409 women received LARC insertions. The program averted an estimated 7165 adult HIV infections at $384 per adult HIV infection averted over a 5-year time horizon. The program also averted 62 265 unintended pregnancies and was cost-saving for measures of cost-per-unintended pregnancy averted, cost-per-couple-year of protection against unintended pregnancy, and cost-per-perinatal HIV infection averted assuming 3 years of LARC use. Our intervention was cost-savings for CFPC outcomes and CVCT was effective and affordable in Zambia. Integrated couples-focused HIV and family planning was feasible, affordable, and leveraged HIV and unintended pregnancy prevention.

Analysis of causes of death among brought-in-dead cases in a third-level Hospital in Lusaka, Republic of Zambia, using the tariff method 2.0 for verbal autopsy: a cross-sectional study

BackgroundOver one third of deaths in Zambian health facilities involve someone who has already died before arrival (i.e., Brough in Dead), and in most BiD cases, the CoD have not been fully analyzed. Therefore, this study was designed to evaluate the function of automated VA based on the Tariff Method 2.0 to identify the CoD among the BiD cases and the usefulness by comparing the data on the death notification form.MethodsThe target site was one third-level hospital in the Republic of Zambia’s capital city. All BiD cases who reached the target health facility from January to August 2017 were included. The deceased’s closest relatives were interviewed using a structured VA questionnaire and the data were analyzed using the SmartVA to determine the CoD at the individual and population level. The CoD were compared with description on the death notification forms by using t-test and Cohen’s kappa coefficient.ResultsOne thousand three hundred seventy-eight and 209 cases were included for persons aged 13 years and older (Adult) and those aged 1 month to 13 years old (Child), respectively. The top CoD for Adults were infectious diseases followed by non-communicable diseases and that for Child were infectious diseases, followed by accidents. The proportion of cases with a determined CoD was significantly higher when using the SmartVA (75% for Adult and 67% for Child) than the death notification form (61%). A proportion (42.7% for Adult and 46% for Child) of the CoD-determined cases matched in both sources, with a low concordance rate for Adult (kappa coefficient = 0.1385) and a good for Child(kappa coefficient = 0.635).ConclusionsThe CoD of the BiD cases were successfully analyzed using the SmartVA for the first time in Zambia. While there many erroneous descriptions on the death notification form, the SmartVA could determine the CoD among more BiD cases. Since the information on the death notification form is reflected in the national vital statistics, more accurate and complete CoD data are required. In order to strengthen the death registration system with accurate CoD, it will be useful to embed the SmartVA in Zambia’s health information system.

Quality of Intrapartum Care: Direct Observations in Selected Health Facilities in Zambia

Approximately 303,000 women die annually while giving birth, worldwide, and more than 99% of the deaths occur in developing countries. In Zambia, a developing country situated in sub-Saharan Africa, most of the maternal mortalities occur during the intrapartum and immediate postpartum periods, arising from postpartum hemorrhage, sepsis, obstructed labor, and hypertensive disorders. Aim: The aim of this study was to assess the quality of intrapartum services provided in health facilities in the country. Methodology: Guided by a descriptive cross sectional design, data were collected from 264 women in labor using a World Health Organization validated observation checklist. Convenience sampling was used to recruit the women, while multistage sampling was used to select four health facilities. The Social Package for Social Sciences, version 23 was used to analyze the data. Results: One health facility met the World Health Organization 80% minimum standard in four out of the five categories used to measure quality in intrapartum care, while the other three met the minimum standard in one category each. Conclusion: Low numbers of midwives, inadequate supplies and equipment were major obstacles to following national and international agreed standards for providing optimal care during intrapartum period. Recommendations: There is need for local and national stakeholders in Zambia to urgently address the structural barriers that were observed, as well as invest in sufficient numbers of adequately trained and motivated midwives.

Social and economic barriers to adherence among patients at Livingstone General Hospital in Zambia.

BackgroundZambia is one of the countries hardest hit by the human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) pandemic with a national HIV prevalence estimated at 14% among those aged 15–49 years in 2012. Antiretroviral therapy (ART) has been available in public health facilities in Zambia since 2003. By early 2016, 65% of the 1.2 million Zambians living with HIV were accessing ART. While access to ART has improved the lives of people living with HIV globally, the lack of adherence to ART is a major challenge to treatment success globally.AimThis article reports on social and economic barriers to ART adherence among HIV patients being attended to at Livingstone General Hospital in Zambia.SettingLivingstone General Hospital is located in the Southern province of Zambia, and had over 7000 patients enrolled for HIV care of whom 3880 patients were on ART.MethodsAn explorative, qualitative study was conducted with 42 patients on ART where data were collected through six focus group discussions (3 male and 3 female groups) and seven in-depth interviews. Data were audio-recorded and transcribed verbatim and subjected to thematic content analysis.ResultsEconomic factors such as poverty and unemployment and the lack of food were reported as major barriers to adherence. Furthermore, social factors such as traditional medicine, religion, lack of family and partner support, and disclosure were also reported as critical barriers to adherence to ART.ConclusionInterventions to improve adherence among ART patients should aim to redress the socio-economic challenges at community and individual levels.

"Being seen" at the clinic: Zambian and South African health worker reflections on the relationship between health facility spatial organisation and items and HIV stigma in 21 health facilities, the HPTN 071 (PopART) study.

Health workers in 21 government health facilities in Zambia and South Africa linked spatial organisation of HIV services and material items signifying HIV-status (for example, coloured client cards) to the risk of People Living with HIV (PLHIV) ‘being seen’ or identified by others. Demarcated HIV services, distinctive client flow and associated-items were considered especially distinguishing. Strategies to circumvent any resulting stigma mostly involved PLHIV avoiding and/or reducing contact with services and health workers reducing visibility of PLHIV through alterations to structures, items and systems. HIV spatial organisation and item adjustments, enacting PLHIV-friendly policies and wider stigma reduction initiatives could combined reduce risks of identification and enhance the privacy of health facility space and diminish stigma.

Myriad of Health Care Financing Reforms in Zambia: Have the Poor Benefited?

Zambia has implemented a number of financing and organizational reforms since the 1990s aimed at increasing efficiency, enhancing equity, and improving health outcomes. This study reviews the distributional impact of these health reforms on enhancing equity at the regional level and for different socioeconomic groups. Data from three nationally representative household surveys were collected, and a benefit incidence analysis was conducted to determine the distributional impact over the period 2010–2015. The results show that distribution of subsidies and utilization of outpatient services at public health facilities in Zambia has consistently been in favor of urban provinces. Further, distribution of health subsidies across the ten provinces in Zambia does not correspond to reported illnesses in each province. The study also shows that utilization of outpatient services at public (hospitals and health centers) and private health facilities is generally in favor of the rich, and utilization of both inpatient and outpatient services at public and private health facilities benefits the rich more than the poor. And although the results show a pro-poor redistribution of benefits across income groups in 2015 compared to 2010 whereby the poorest two income groups received more than a 20% share of benefits in each quintile, the benefits were still lower than their health needs. This is contrary to the richest two income groups whose share of benefits was higher than their health needs in both 2010 and 2015. The study concludes that Zambia has not yet fully attained its long-term health reform vision of “equity of access to quality health care” despite years of successive health reforms. The study calls for the Zambian government to complement strategies on financial risk protection with deliberate supply- and demand-side actions in order to enhance equity. Improvements in long- and short-term planning and regular monitoring and evaluation are critical.

Associations between health systems capacity and mother-to-child HIV prevention program outcomes in Zambia.

IntroductionZambia has made substantial investments in health systems capacity, yet it remains unclear whether improved service quality improves outcomes. We investigated the association between health system capacity and use of prevention of mother-to-child HIV transmission (PMTCT) services in Zambia.Materials and methodsWe analyzed data from two studies conducted in rural and semi-urban Lusaka Province in 2014–2015. Health system capacity, our primary exposure, was measured with a validated balanced scorecard approach. Based on WHO building blocks for health systems strengthening, we derived overall and domain-specific facility scores (range: 0–100), with higher scores indicating greater capacity. Our outcome, community-level maternal antiretroviral drug use at 12 months postpartum, was measured via self-report in a large cohort study evaluating PMTCT program impact. Associations between health systems capacity and our outcome were analyzed via linear regression.ResultsAmong 29 facilities, median overall facility score was 72 (IQR:67–74). Median domain scores were: patient satisfaction 75 (IQR 71–78); human resources 85 (IQR:63–87); finance 50 (IQR:50–67); governance 82 (IQR:74–91); service capacity 77 (IQR:68–79); service provision 60 (IQR:52–76). Our programmatic outcome was measured from 804 HIV-infected mothers. Median community-level antiretroviral use at 12 months was 81% (IQR:69–89%). Patient satisfaction was the only domain score significantly associated with 12-month maternal antiretroviral use (β:0.22; p = 0.02). When we excluded the human resources and finance domains, we found a positive association between composite 4-domain facility score and 12-month maternal antiretroviral use in peri-urban but not rural facilities.ConclusionsIn these Zambian health facilities, patient satisfaction was positively associated with maternal antiretroviral 12 months postpartum. The association between overall health system capacity and maternal antiretroviral drug use was stronger in peri-urban versus rural facilities. Additional work is needed to guide strategic investments for improved outcomes in HIV and broader maternal-child health region-wide.

Listening to the community: Using formative research to strengthen maternity waiting homes in Zambia.

BackgroundThe WHO recommends maternity waiting homes (MWH) as one intervention to improve maternal and newborn health. However, persistent structural, cultural and financial barriers in their design and implementation have resulted in mixed success in both their uptake and utilization. Guidance is needed on how to design a MWH intervention that is acceptable and sustainable. Using formative research and guided by a sustainability framework for health programs, we systematically collected data from key stakeholders and potential users in order to design a MWH intervention in Zambia that could overcome multi-dimensional barriers to accessing facility delivery, be acceptable to the community and be financially and operationally sustainable.Methods and findingsWe used a concurrent triangulation study design and mixed methods. We used free listing to gather input from a total of 167 randomly sampled women who were pregnant or had a child under the age of two (n = 59), men with a child under the age of two (n = 53), and community elders (n = 55) living in the catchment areas of four rural health facilities in Zambia. We conducted 17 focus group discussions (n = 135) among a purposive sample of pregnant women (n = 33), mothers-in-law (n = 32), traditional birth attendants or community maternal health promoters (n = 38), and men with a child under two (n = 32). We administered 38 semi-structured interviews with key informants who were identified by free list respondents as having a stake in the condition and use of MWHs. Lastly, we projected fixed and variable recurrent costs for operating a MWH.Respondents most frequently mentioned distance, roads, transport, and the quality of MWHs and health facilities as the major problems facing pregnant women in their communities. They also cited inadequate advanced planning for delivery and the lack of access to delivery supplies and baby clothes as other problems. Respondents identified the main problems of MWHs specifically as over-crowding, poor infrastructure, lack of amenities, safety concerns, and cultural issues. To support operational sustainability, community members were willing to participate on oversight committees and contribute labor. The annual fixed recurrent cost per 10-bed MWH was estimated as USD543, though providing food and charcoal added another $3,000USD. Respondents identified water pumps, an agriculture shop, a shop for baby clothes and general goods, and grinding mills as needs in their communities that could potentially be linked with an MWH for financial sustainability.ConclusionsFindings informed the development of an intervention model for renovating existing MWH or constructing new MWH that meets community standards of safety, comfort and services offered and is aligned with government policies related to facility construction, ownership, and access to health services. The basic strategies of the new MWH model include improving community acceptability, strengthening governance and accountability, and building upon existing efforts to foster financial and operational sustainability. The proposed model addresses the problems cited by our respondents and challenges to MWHs identified by in previous studies and elicits opportunities for social enterprises that could serve the dual purpose of meeting a community need and generating revenue for the MWH.

VAetiology of Diarrhoea in Children Under Five in Zambia Detected Using Luminex xTAG Gastrointestinal Pathogen Panel

Background: We aimed to document viral, bacterial, and protozoan enteric pathogens responsible of causing moderate-to-severe diarrhoea among children under five presenting at public health facilities in Zambia following the introduction of rotavirus vaccination. Methods: This was a cross-sectional study in which clinical data and stool samples were collected between July 2012 and October 2013 from children under five years presenting to outpatient clinics in Lusaka province with moderate-tosevere diarrhoea. The study was conducted during the early months post rotavirus vaccine introduction in Zambia. We used Luminex x-TAG® gastrointestinal pathogen panel to simultaneously detect enteric viruses, bacteria and protozoa from the stool samples. We applied the population attributable fraction to estimate pathogen-specific burden of moderate-to-severe diarrhoea. Results: We analysed 1,135 unique stool samples with clinical data, of which 56% had received one or full dose rotavirus vaccination. The median age was 14 months (IQR=8, 22). The prevalence of moderate-to-severe diarrhoea was estimated as 18.9% (95%CI=16.7, 21.2). The most attributable cases of moderate-to-severe diarrhoea were due to rotavirus {attributable fraction=24.5%; 95%CI=(5.4, 39.7)} followed by Shigella spp. {attributable fraction=6.7%; 95%CI=(0.1, 15.5)}. The top 5 enteric pathogens detected among children were rotavirus (67.6%), Adenovirus (41.5%), ETEC (40.7%), Salmonella (38.4%) and Giardia (37.0%). Conclusion: We found that about one-third of moderate-to-severe diarrhoea among children were attributable to rotavirus and shigella spp.

Assessing care-givers' satisfaction with child immunisation services in Zambia: Evidence from a national survey.

The main aim of this study was to assess care-giver satisfaction with vaccination services in public health facilities in Zambia, and examine its determinants. This study used data from a recent population-based household survey, conducted from May to August 2015. Respondent satisfaction with vaccination services received during the last visit was measured on a five point Likert scale ranging from 1 to 5. We used an ordered logistic regression model to analyse the significance of perceived quality of vaccination services, immunisation delivery mode and a range of individual characteristics in predicting care-giver satisfaction. Findings show that one in five care givers were unsatisfied with the vaccination services that they had received, with rural populations showing a significantly higher level of satisfaction. Poor quality of care, defined by long waiting times, poor quality of communication between health staff and care givers, long distance to vaccination sites, mode of delivery, and personal characteristics were among major factors driving care-giver satisfaction ratings. We also find that receiving a vaccination at outreach mode of delivery was associated with higher odds of greater satisfaction compared to on-facility vaccination services. The odds of satisfaction were lower for respondents living further away from a health facility, which emphasizes the importance of access in seeking vaccination services. These findings suggest that major improvements in quality of vaccination and service organisation will be needed to increase client satisfaction and service utilisation.

Moving from legality to reality: how medical abortion methods were introduced with implementation science in Zambia

BackgroundAlthough abortion is technically legal in Zambia, the reality is far more complicated. This study describes the process and results of galvanizing access to medical abortion where abortion has been legal for many years, but provision severely limited. It highlights the challenges and successes of scaling up abortion care using implementation science to document 2 years of implementation.MethodsAn intervention between the Ministry of Health, University Teaching Hospital and the international organization Ipas, was established to introduce medical abortion and to address the lack of understanding and implementation of the country’s abortion law. An implementation science model was used to evaluate effectiveness and glean lessons for other countries about bringing safe and legal abortion services to scale. The intervention involved the provision of Comprehensive Abortion Care services in 28 public health facilities in Zambia for a 2 year period, August 2009 to September 2011. The study focused on three main areas: building health worker capacity in public facilities and introducing medical abortion, working with pharmacists to provide improved information on medical abortion, and community engagement and mobilization to increase knowledge of abortion services and rights through stronger health system and community partnerships.ResultsAfter 2 years, 25 of 28 sites provided abortion services, caring for more than 13,000 women during the intervention. For the first time, abortion was decentralized, 19% of all abortion care was performed in health centers. At the end of the intervention, all providing facilities had managers supportive of continuing legal abortion services. When asked about the impact of medical abortion provision, a number of providers reported that medical abortion improved their ability to provide affordable safe abortion. In neighboring pharmacies only 19% of mystery clients visiting them were offered misoprostol for purchase at baseline, this increased to 47% after the intervention. Despite progress in attitudes towards abortion clients, such as empathy, and improved community engagement, the evaluation revealed continuing stigma on both provider and client sides.ConclusionsThese findings provide a case study of the medical abortion introduction in Zambia and offer important lessons for expanding safe and legal abortion access in similar settings across Africa.

FIELD PERFORMANCE OF POINT-OF-CARE TO DETERMINE HBSAG TEST FOR DIAGNOSIS OF ACTIVE HEPATITIS B VIRUS INFECTION IN ZAMBIA

BackgroundIn Zambia, we evaluated the field performance of a rapid point-of-care test for hepatitis B surface antigen (HBsAg) which could support decentralisation and scale-up of care and treatment of chronic...

Survival of people on antiretroviral treatment in Zambia: a retrospective cohort analysis of HIV clients on ART.

IntroductionProvision of free anti-retroviral therapy in Zambia started in June 2004. There were only 15,000 people on treatment as at December that year, mainly due to lack of access. This number rose to 580,000 people as at December 2013. The general objective of this study was to determine survival of people on ART and to examine associated predictors for survival.MethodsThe study included ART patients enrolled between the year 2002 and 2013 (n=10,395) in 285 health facilities in Zambia. Patient files were analyzed retrospectively. The study used Kaplan Meier and Cox-proportional hazard models to describe the relationship between lost to follow up and age, sex, baseline CD4 cell count and weight.ResultsResults showed that lost to follow up accounted for 90% of the clients that had dropped out, while 10% was to deaths. Low baseline CD4 count (p-value 0.001, HR 0.9994, (95% CI 0.9993, 0.9996) at initiation was associated with lost to follow up together with weight at initiation (p-value 0.031, HR 0.9987 at 95% CI (0.9975, 0.9998)) of ART.ConclusionThis study has demonstrated that lost to follow up is a substantial contributing factor to drop outs among HIV patients on treatment. Strengthening of community treatment supporters especially immediate family members in emphasizing to the client the need to continue treatment is necessary. The health facility could do more in emphasizing the importance of treatment especially in the initial stages. Further, in order to reduce opportunistic infections and probable deaths during treatment, cotrimoxazole prophylaxis should be maintained so as to raise the CD4 levels. Improved nutritional assessment and counseling to boost the nutritional status of the clients throughout should be encouraged.

Rapid diagnostic tests for malaria and health workers' adherence to test results at health facilities in Zambia.

BackgroundIn Zambia, there has been a large scaling up of interventions to control malaria in recent years including the deployment of rapid diagnostic tests (RDTs) to improve malaria surveillance data as well as guide malaria treatment in health facilities. The practical challenge is the impact of RDT results on subsequent management of patients. This study explored the role of RDTs in malaria diagnosis and the health workers’ adherence to test results.MethodsAn observational prospective study was carried out at health centres in four districts, namely Chibombo, Chingola, Chipata, and Choma. Children under the age of five years with history of fever were recruited and the clinicians’ use of RDT results was observed to establish whether prescriptions were issued prior to the availability of parasitological results or after, and whether RDT results influenced their prescriptions.ResultsOf the 2, 393 recruited children, 2, 264 had both RDT and microscopic results. Two in three (68.6%) children were treated with anti-malarials despite negative RDT results and almost half (46.2%) of these were prescribed Coartem®. Only 465 (19.4%) of the 2,393 children were prescribed drugs before receiving laboratory results. A total of 76.5% children were prescribed drugs after laboratory results. Children with RDT positive results were 2.66 (95% CI (2.00, 3.55)) times more likely to be prescribed anti-malarial drugs. Children who presented with fever at admission (although history of fever or presence of fever at admission was an entry criterion) were 42% less likely to be prescribed an anti-malarial drug compared to children who had no fever (AOR = 0.58; 95% CI (0.52, 0.65)). It was noted that proportions of children who were RDT- and microscopy-positive significantly declined over the years from 2005 to 2008.ConclusionsRDTs may contribute to treatment of febrile illness by confirming malaria cases from non-malaria cases in children under the age of five. However, the adherence of the health workers to prescribing anti-malarials to only RDT-positive cases at health facility level will still require to be explored further as their role is crucial in more precise reporting of malaria cases in this era towards malaria elimination as the target.

Assessing the quality of HIV/AIDS services at military health facilities in Zambia

After rapidly scaling up HIV/AIDS-related health services, the Zambian Defence Force (ZDF) has become concerned with assuring their quality. This evaluation assesses provider performance at eight ZDF facilities based on direct observations of 191 antenatal care (ANC) consultations and 175 follow-up consultations for antiretroviral therapy (ART). In addition, 43 ZDF health providers were interviewed about the work environment and service quality. On-the-job performance varied widely: providers completed as few as 0% and as many as 100% of tasks associated with each performance standard. Overall scores averaged 66% (range: 47-93%) for ANC consultations and 60% (range: 37-100%) for ART consultations. Perceptions of the work environment were generally positive, but 57% of providers lack confidence in their clinical skills and 42% think staffing is insufficient. These findings, which point to the unique opportunities and challenges in the military setting, will be used to guide a quality improvement initiative.

Quality of antenatal care in Zambia: a national assessment.

BackgroundAntenatal care (ANC) is one of the recommended interventions to reduce maternal and neonatal mortality. Yet in most Sub-Saharan African countries, high rates of ANC coverage coexist with high maternal and neonatal mortality. This disconnect has fueled calls to focus on the quality of ANC services. However, little conceptual or empirical work exists on the measurement of ANC quality at health facilities in low-income countries. We developed a classification tool and assessed the level of ANC service provision at health facilities in Zambia on a national scale and compared this to the quality of ANC received by expectant mothers.MethodsWe analysed two national datasets with detailed antenatal provider and user information, the 2005 Zambia Health Facility Census and the 2007 Zambia Demographic and Health Survey (DHS), to describe the level of ANC service provision at 1,299 antenatal facilities in 2005 and the quality of ANC received by 4,148 mothers between 2002 and 2007.ResultsWe found that only 45 antenatal facilities (3%) fulfilled our developed criteria for optimum ANC service, while 47% of facilities provided adequate service, and the remaining 50% offered inadequate service. Although 94% of mothers reported at least one ANC visit with a skilled health worker and 60% attended at least four visits, only 29% of mothers received good quality ANC, and only 8% of mothers received good quality ANC and attended in the first trimester.ConclusionsDHS data can be used to monitor “effective ANC coverage” which can be far below ANC coverage as estimated by current indicators. This “quality gap” indicates missed opportunities at ANC for delivering effective interventions. Evaluating the level of ANC provision at health facilities is an efficient way to detect where deficiencies are located in the system and could serve as a monitoring tool to evaluate country progress.

Availability and distribution of, and geographic access to emergency obstetric care in Zambia

Objective To assess the availability and coverage of emergency obstetric care (EmOC) services in Zambia. Methods Reported provision of EmOC signal functions in the Zambian Health Facility Census and additional criteria on staffing, opening hours, and referral capacity were used to classify all Zambian health facilities as providing comprehensive EmOC, basic EmOC, or more limited care. Geographic accessibility of EmOC services was estimated by linking health facility data with data from the Zambian population census. Results Few Zambian health facilities provided all basic EmOC signal functions and had qualified health professionals available on a 24-hour basis. Of the 1131 Zambian delivery facilities, 135 (12%) were classified as providing EmOC. Zambia nearly met the UN EmOC density benchmarks nationally, but EmOC facilities and health professionals were unevenly distributed between provinces. Geographic access to EmOC services in rural areas was low; in most provinces, less than 25% of the population lived within 15 km of an EmOC facility. Conclusion A national Health Facility Census with geographic information is a valuable tool for assessing service availability and coverage at national and subnational levels. Simultaneously assessing health worker density and geographic access adds crucial information.

Task sharing in Zambia: HIV service scale-up compounds the human resource crisis.

BackgroundConsiderable attention has been given by policy makers and researchers to the human resources for health crisis in Africa. However, little attention has been paid to quantifying health facility-level trends in health worker numbers, distribution and workload, despite growing demands on health workers due to the availability of new funds for HIV/AIDS control scale-up. This study analyses and reports trends in HIV and non-HIV ambulatory service workloads on clinical staff in urban and rural district level facilities.MethodsStructured surveys of health facility managers, and health services covering 2005-07 were conducted in three districts of Zambia in 2008 (two urban and one rural), to fill this evidence gap. Intra-facility analyses were conducted, comparing trends in HIV and non-HIV service utilisation with staff trends.ResultsClinical staff (doctors, nurses and nurse-midwives, and clinical officers) numbers and staff population densities fell slightly, with lower ratios of staff to population in the rural district. The ratios of antenatal care and family planning registrants to nurses/nurse-midwives were highest at baseline and increased further at the rural facilities over the three years, while daily outpatient department (OPD) workload in urban facilities fell below that in rural facilities. HIV workload, as measured by numbers of clients receiving antiretroviral treatment (ART) and prevention of mother to child transmission (PMTCT) per facility staff member, was highest in the capital city, but increased rapidly in all three districts. The analysis suggests evidence of task sharing, in that staff designated by managers as ART and PMTCT workers made up a higher proportion of frontline service providers by 2007.ConclusionsThis analysis of workforce patterns across 30 facilities in three districts of Zambia illustrates that the remarkable achievements in scaling-up HIV/AIDS service delivery has been on the back of sustained non-HIV workload levels, increasing HIV workload and stagnant health worker numbers. The findings are based on an analysis of routine data that are available to district and national managers. Mixed methods research is needed, combining quantitative analyses of routine health information with follow-up qualitative interviews, to explore and explain workload changes, and to identify and measure where problems are most acute, so that decision makers can respond appropriately. This study provides quantitative evidence of a human resource crisis in health facilities in Zambia, which may be more acute in rural areas.

Cost-effectiveness analysis of the available strategies for diagnosing malaria in outpatient clinics in Zambia.

BackgroundMalaria in Zambia accounts for about 4 million clinical cases and 8 000 deaths annually. Artemether-lumefantrine (ACT), a relatively expensive drug, is being used as first line treatment of uncomplicated malaria. However, diagnostic capacity in Zambia is low, leading to potentially avoidable wastage of drugs due to unnecessary anti malarial treatment.MethodsA cost-effectiveness evaluation of the three current alternatives to malaria diagnosis (clinical, microscopy and Rapid Diagnostic Tests- RDT) was conducted in 12 facilities from 4 districts in Zambia. The analysis was conducted along an observational study, thus reflecting practice in health facilities under routine conditions. Average and incremental cost effectiveness ratios were estimated from the providers' perspective. Effectiveness was measured in relation to malaria cases correctly diagnosed by each strategy.ResultsAverage cost-effectiveness ratios show that RDTs were more efficient (US$ 6.5) than either microscopy (US$ 11.9) or clinical diagnosis (US$ 17.1) for malaria case correctly diagnosed. In relation to clinical diagnoses the incremental cost per case correctly diagnosed and treated was US$ 2.6 and US$ 9.6 for RDT and microscopy respectively. RDTs would be much cheaper to scale up than microscopy. The findings were robust to changes in assumptions and various parameters.ConclusionRDTs were the most cost effective method at correctly diagnosing malaria in primary health facilities in Zambia when compared to clinical and microscopy strategies. However, the treatment prescription practices of the health workers can impact on the potential that a diagnostic test has to lead to savings on antimalarials. The results of this study will serve to inform policy makers on which alternatives will be most efficient in reducing malaria misdiagnosis by taking into account both the costs and effects of each strategy.
