Zambia health sector public expenditure review : accounting for resources to improve effective service coverage
'Zambia Health Sector Public Expenditure Review' portrays the performance of the health sector in Zambia using quantitative techniques. While there have been a number of health sector assessments in the country, they have relied on qualitative and anecdotal evidence for the most part. For the first time, this public expenditure review of the health sector brings together the results of three separate but related analytical efforts: multi-year national health accounts, a public expenditure tracking and quality of service delivery survey, and resource and impact modeling using the Marginal Budgeting for Bottlenecks software. These exercises combine to yield more powerful findings on the weaknesses and prospects of the Zambian health system.

Working in health : financing and managing the public sector health workforce
'Working in Health' addresses two key questions related to health workforce policy in developing countries: • What is the impact of government wage bill policies on the size of the health wage bill and on health workforce staffing levels in the public sector? • Do current human resources management policies and practices lead to effective use of wage bill resources in the public sector? Health workers play a key role in increasing access to health services for poor people in developing countries. Global and country level estimates show that staffing levels in many developing countries—particularly in sub-Saharan Africa—are far below what is needed to deliver essential health services to the population. One factor that potentially limits scaling up the health workforce in developing countries is the government overall wage bill policy which sometimes creates restrictions. Through a review of literature, analysis of data, and country case studies in Kenya, Zambia, Rwanda, and the Dominican Republic, this book examines the process that determines the health wage bill budget in the public sector, how this is linked to overall wage bill policies, how this affects staffing levels in the health sector, and the relevant policy options. But staff numbers are not everything and more money for the health wage bill alone will not solve the health workforce problems of developing countries. 'Working in Health' looks at how effectively governments use the available wage bill resources in the health sector and policy options. Policies and practices in recruitment, deployment, promotion, transfer, sanctioning, and remuneration for health workers are reviewed to identify their influence on budget execution rates, geographic distribution, and productivity of health workers.

Towards a bottom-up understanding of antimicrobial use and resistance on the farm: A knowledge, attitudes, and practices survey across livestock systems in five African countries
The nutritional and economic potentials of livestock systems are compromised by the emergence and spread of antimicrobial resistance. A major driver of resistance is the misuse and abuse of antimicrobial drugs. The likelihood of misuse may be elevated in low- and middle-income countries where limited professional veterinary services and inadequately controlled access to drugs are assumed to promote non-prudent practices (e.g., self-administration of drugs). The extent of these practices, as well as the knowledge and attitudes motivating them, are largely unknown within most agricultural communities in low- and middle-income countries. The main objective of this study was to document dimensions of knowledge, attitudes and practices related to antimicrobial use and antimicrobial resistance in livestock systems and identify the livelihood factors associated with these dimensions. A mixed-methods ethnographic approach was used to survey households keeping layers in Ghana (N = 110) and Kenya (N = 76), pastoralists keeping cattle, sheep, and goats in Tanzania (N = 195), and broiler farmers in Zambia (N = 198), and Zimbabwe (N = 298). Across countries, we find that it is individuals who live or work at the farm who draw upon their knowledge and experiences to make decisions regarding antimicrobial use and related practices. Input from animal health professionals is rare and antimicrobials are sourced at local, privately owned agrovet drug shops. We also find that knowledge, attitudes, and particularly practices significantly varied across countries, with poultry farmers holding more knowledge, desirable attitudes, and prudent practices compared to pastoralist households. Multivariate models showed that variation in knowledge, attitudes and practices is related to several factors, including gender, disease dynamics on the farm, and source of animal health information. Study results emphasize that interventions to limit antimicrobial resistance should be founded upon a bottom-up understanding of antimicrobial use at the farm-level given limited input from animal health professionals and under-resourced regulatory capacities within most low- and middle-income countries. Establishing this bottom-up understanding across cultures and production systems will inform the development and implementation of the behavioral change interventions to combat antimicrobial resistance globally.

Economic cost analysis of door‐to‐door community‐based distribution of HIV self‐test kits in Malawi, Zambia and Zimbabwe
Introduction
HIV self‐testing (HIVST) is recommended by the World Health Organization in addition to other testing modalities to increase uptake of HIV testing, particularly among harder‐to‐reach populations. This study provides the first empirical evidence of the costs of door‐to‐door community‐based HIVST distribution in Malawi, Zambia and Zimbabwe.
Methods
HIVST kits were distributed door‐to‐door in 71 sites across Malawi, Zambia and Zimbabwe from June 2016 to May 2017. Programme expenditures, supplemented by on‐site observation and monitoring and evaluation data were used to estimate total economic and unit costs of HIVST distribution, by input and site. Inputs were categorized into start‐up, capital and recurrent costs. Sensitivity and scenario analyses were performed to assess the impact of key parameters on unit costs.
Results
In total, 152,671, 103,589 and 93,459 HIVST kits were distributed in Malawi, Zambia and Zimbabwe over 12, 11 and 10 months respectively. Across these countries, 43% to 51% of HIVST kits were distributed to men. The average cost per HIVST kit distributed was US$8.15, US$16.42 and US$13.84 in Malawi, Zambia and Zimbabwe, respectively, with pronounced intersite variation within countries driven largely by site‐level fixed costs. Site‐level recurrent costs were 70% to 92% of full costs and 20% to 62% higher than routine HIV testing services (HTS) costs. Personnel costs contributed from 26% to 52% of total costs across countries reflecting differences in remuneration approaches and country GDP.
Conclusions
These early door‐to‐door community HIVST distribution programmes show large potential, both for reaching untested populations and for substantial economies of scale as HIVST programmes scale‐up and mature. From a societal perspective, the costs of HIVST appear similar to conventional HTS, with the higher providers’ costs substantially offsetting user costs. Future approaches to minimizing cost and/or maximize testing coverage could include unpaid door‐to‐door community‐led distribution to reach end‐users and integrating HIVST into routine clinical services via direct or secondary distribution strategies with lower fixed costs.

Geographic factors associated with SARS-CoV-2 prevalence during the first wave − 6 districts in Zambia, July 2020
Background
Geographical factors can affect infectious disease transmission, including SARS-CoV-2, a virus that is spread through respiratory secretions. Prioritization of surveillance and response activities during a pandemic can be informed by a pathogen’s geographical transmission patterns. We assessed the relationship between geographical factors and SARS-CoV-2 prevalence in Zambia.
Methods
We did a cross-sectional study of SARS-CoV-2 prevalence in six districts in July 2020, which was during the upslope of the first wave in Zambia. In each district, 16 Standard Enumeration Areas (SEAs) were randomly selected and 20 households from each SEA were sampled. The SEA PCR prevalence was calculated as the number of persons testing PCR positive for SARS-CoV-2 in the SEA times the individual sampling weight for the SEA divided by the SEA population. We analysed SEA geographical data for population density, socioeconomic status (SES) (with lower scores indicating reduced vulnerability), literacy, access to water, and sanitation, and hygiene (WASH) factors. Gaussian conditional autoregressive (CAR) models and Generalised estimating equations (GEE) were used to measure adjusted prevalence Ratios (aPRs) and 95% confidence intervals (CIs) for SARS-CoV-2 prevalence with geographical factors, after adjusting for clustering by district, in R.
Results
Overall, the median SARS-CoV-2 prevalence in the 96 SEAs was 41.7 (Interquartile range (IQR), 0.0-96.2) infections per 1000 persons. In the multivariable CAR analysis, increasing SES vulnerability was associated with lower SARS-CoV-2 prevalence (aPR) = 0.85, 95% CI: 0.78–0.94). Conversely, urban SEAs and poor access to WASH were associated with a higher SARS-CoV-2 prevalence (aPR = 1.73, 95% CI: 1.46–2.03, No soap: aPR = 1.47, 95% CI: 1.05–2.05, households without piped water: aPR = 1.32, 95% CI: 1.05–1.65, 30 min to fetch water: aPR = 23.39, 95% CI: 8.89–61.52). Findings were similar in the multivariable GEE analysis.
Conclusions
SARS-CoV-2 prevalence was higher in wealthier, urban EAs, with poor access to WASH. As this study was conducted early in the first wave could have impacted our findings. Additional analyses from subsequent waves could confirm if these findings persist. During the beginning of a COVID-19 wave in Zambia, surveillance and response activities should be focused on urban population centres and improving access to WASH.

Economic evaluation of thermal ablation compared to cryotherapy and loop diathermy in a screen-and-treat approach to cervical cancer, Zambia
To estimate the financial and economic costs and the cost-effectiveness of thermal ablation compared to cryotherapy and loop diathermy within a screen-and-treat approach to cervical cancer screening in Zambia.
We analysed costs within a randomized controlled trial in which women eligible for ablative treatment after cervical cancer screening were assigned to one of three treatment arms: thermal ablation, cryotherapy or loop diathermy. We used a microcosting approach to calculate programme, personnel, equipment and consumable costs for two groups: women treated without follow-up (screened-and-treated) and women who completed follow-up (follow-up-completed). We also estimated trial costs and projected costs if the screen-and-treat approach were to be integrated into routine cervical cancer services. To assess how cost-effective the treatments were, we used a decision tree model.
Out of the 3124 women who were screened-and-treated, 2386 (76.4%) completed follow-up. In the trial scenario, costs for thermal ablation were lower than cryotherapy and loop diathermy, both per screened-and-treated woman (39.6 United States dollars (US$) versus US$ 42.3 and US$ 50.6, respectively) and per follow-up-completed woman (US$ 55.1 versus US$ 57.9 and US$ 66.2, respectively). In the routine scenario, costs for thermal ablation were also lower than for other treatments (US$ 12.7 versus US$ 15.6 and US$ 34.9, respectively, for screen-and-treat) due to significantly lower personnel costs. Thermal ablation was cost-effective compared to cryotherapy and loop diathermy.
Our study suggests that thermal ablation is a cost-effective option for the screen-and-treat approach to cervical cancer screening compared with cryotherapy and loop diathermy.

The silent epidemic: unravelling NCD risk clusters and socioeconomic determinants in Zambia
Introduction
Non-communicable diseases (NCDs) are a public health challenge in Zambia. This is driven by economic transitions, urbanization, and lifestyle changes. This study examines how NCDs cluster and relate to socioeconomic factors such as education, income, and employment.
Methodology
Using data from the 2017 Zambia WHO STEPS survey (
N
= 4,302 adults, mean age: 36.57 years), Latent Class Analysis identified NCD risk profiles, and multinomial logistic regression assessed their associations with socioeconomic determinants.
Results
Three NCD risk groups emerged: Low-Risk (12.0%), Intermediate-Risk (64.3%), and High-Risk (23.7%). The Low-Risk group maintained healthy lifestyles. The Intermediate-Risk group, the most prevalent, showed borderline metabolic indicators and occasional unhealthy behaviours. The High-Risk group exhibited multiple risk factors, including obesity, hypertension, diabetes, and substance use. Males had 22.8 times higher odds of being in the High-Risk group than females. Surprisingly, higher education increased the odds of being in the Moderate- and High-Risk groups.
Conclusion
NCD prevention in Zambia requires risk-stratified strategies: primary prevention for Intermediate-Risk groups and intensive intervention for High-Risk populations. Critical policy actions include taxing tobacco, alcohol, and unhealthy foods; expanding universal screening; integrating NCD care into primary health systems; and addressing urbanization, cultural practices, and healthcare disparities.

The clinical profile and outcomes of drug resistant tuberculosis in Central Province of Zambia
Background
The emergence of Drug Resistant Tuberculosis (DR-TB) is one of the main public health and economic problems facing the world today. DR-TB affects mostly those in economically productive years and prevents them from being part of the workforce needed for economic growth. The aim of this study was to determine the Clinical Profile and Outcomes of DR-TB in Central Province of Zambia.
Methods
This was a retrospective cross sectional study that involved a review of records of patients with confirmed DR-TB who were managed at Kabwe Central Hospital’s Multi-Drug Resistant TB (MDR-TB) Ward from the year 2017 to 2021. 183 patients were managed during this period and all were recruited in the study. Data was collected from DR-TB registers and patient files and then entered in SPSS version 22 where all statistical analyses were performed.
Results
The study revealed that the prevalence of DR-TB among registered TB patients in Central Province was 1.4%. Majority of those affected were adults between the ages of 26 and 45 years (63.9%). The study also found that more than half of the patients were from Kabwe District (60.7%). Other districts with significant number of cases included Kapiri Mposhi 19 (10.4%), Chibombo 12 (6.6%), Chisamba 10 (5.5%), Mumbwa 7 (3.8%) and Mkushi 7 (3.8%). Furthermore, the analysis established that most of the patients had RR-TB (89.6%). 9.3% had MDR-TB, 0.5% had IR-TB and 0.5% had XDR-TB. RR-TB was present in 93.8% of new cases and 88.9% of relapse cases. MDR-TB was present in 6.2% of new cases and 10% of relapse cases. With regard to outcomes of DR-TB, the investigation revealed that 16.9% of the patients had been declared cured, 45.9% had completed treatment, 6% were lost to follow up and 21.3% had died. Risk factors for mortality on multivariate analysis included age 36–45 years (adjusted odds ratio [aOR] 0.253, 95% CI [0.70–0.908]
p
= 0.035) and male gender (aOR 0.261, 95% CI [0.107–0.638]
p
= 0.003).
Conclusion
The research has shown beyond doubt that the burden of DR-TB in Central Province is high. The study recommends putting measures in place that will help improve surveillance, early detection, early initiation of treatment and proper follow up of patients.
