Background: Zambia has recently articulated an ambitious national health program designed to meeting health-related MDGs. Public expectations are high and Zambia continues to receive significant resources from global and bilateral donors to support its health agenda. Although the lack of adequate resources presents the most important constraint, the efficiency with which available resources are being utilised is another challenge that cannot be overlooked. Inefficiency in producing health care undermines the service coverage potential of the health system. This paper estimates the technical efficiency of a sample of hospitals in Zambia.
Methods: Efficiency is measured using a DEA model. Vectors of hospital inputs and outputs, representing hospital expended resources and output profiles respectively, were specified and measured. The data were gathered from a sample of 30 hospitals throughout Zambia. The model estimates an efficiency score for each hospital. A decomposition of technical efficiency into scale and congestion is also provided.
Results: Results show that overall Zambian hospitals are operating at 67% level of efficiency, implying that significant resources are being wasted. Only 40% of hospitals were efficient in relative terms. The study further reveals that the size of hospitals is a major source of inefficiency. Input congestion is also found to be a source of hospital inefficiency.
Conclusion: This study has demonstrated that inefficiency of resource use in hospitals is significant. Policy attention is drawn to unsuitable hospital scale of operation and low productivity of some inputs as factors that reinforce each other to make Zambian hospitals technically inefficient at producing and delivering services. It is argued that such evidence of substantial inefficiency would undermine Zambia's prospects of achieving its health goals.

Using Minimally Invasive Tissue Sampling and Determination of Cause of Death to Establish Etiologies of Community Respiratory Deaths Among Zambian Infants and Children.
J Pediatric Infect Dis Soc

Bill & Melinda Gates Foundation, Seattle, Washington, USA.
In low-to-middle-income countries, acute lower respiratory infection (ALRI) remains the leading infectious cause of death among infants and children under 5 years old. Case-control studies based on upper respiratory sampling have informed current understandings of ALRI etiologies; in contrast, minimally invasive tissue sampling (MITS) offers a method of directly interrogating lower respiratory tract pathogens to establish etiologic distributions. This study performed in the postmortem setting used MITS and a Determination of Cause of Death (DeCoDe) panel to elucidate the causes of fatal pneumonia in the community in Lusaka, Zambia.

Background: How common it is with the presence of human papillomavirus (HPV) in the healthy and diseased oral cavity is largely unknown for Africans. In this cross-sectional study we assessed the prevalence of oral HPV and the risk factors associated with HPV contraction including sexual practice in the urban and rural Zambian population.
Methods: Urban (N = 188) and rural (N = 211) Zambian adults aged 21 years and older living in Ndola and Mansa, respectively, were interviewed about demographical data, oral and coital sexual history and tobacco and alcohol use.
Effects on maternal and pregnancy outcomes of first-trimester malaria infection among nulliparous women from Kenya, Zambia, and the Democratic Republic of the Congo.

Article Synopsis
- A study was conducted to evaluate the effects of malaria infection during the first trimester of pregnancy on adverse outcomes for mothers and babies in Kenya, Zambia, and the Democratic Republic of the Congo.
- Using rigorous testing methods, researchers found specific risks such as higher rates of preterm birth and anemia later in pregnancy among affected women.
- The findings suggest that first-trimester malaria is linked to increased prevalence of anemia and highlight the need for more research on its impact on other pregnancy complications like preterm birth and low birth weight.
Methods for measuring body composition in Zambian adolescents living with HIV.
PLOS Glob Public Health

Institute of Child Health, University College London, London, United Kingdom.
Article Synopsis
- Body composition assessment is crucial for managing health conditions like HIV, especially in resource-limited settings such as Africa.
- Researchers tested methods like dual-energy X-ray absorptiometry (DXA), bioelectrical impedance (BIA), and various anthropometric measures on 420 HIV-infected adolescents in Zambia.
- While BIA and anthropometry provided some data, they were not reliable enough for tracking changes in body composition compared to DXA, with BIA potentially being useful for identifying general trends when DXA isn’t available.

Article Synopsis
- Neurocritical illnesses often lead to increased mortality in low-resource countries, and early neurodeterioration (END) may help identify high-risk patients for better care.
- A study conducted in Zambia monitored neurology inpatients to assess the impact of END, defined as a decline in the Glasgow Coma Scale (GCS) within three days of admission.
- The results showed that 18% of patients experienced END, significantly increasing their risk of death (72% vs 11% mortality), with common causes of death being aspiration pneumonia and sepsis, indicating a need for targeted interventions.
