    Childhood Lead Exposure After the Phaseout of Leaded Gasoline: An Ecological Study of School-Age Children in Kampala, Uganda
    (Environmental health perspectives, 2010) Lauren, K. Graber; Daniel, Asher; Natasha, Anandaraja; Richard, F. Bopp; Karen, Merrill; Mark, R. Cullen; Luboga, Samuel; Leonardo, Trasande
    Background Tetraethyl lead was phased out of gasoline in Uganda in 2005. Recent mitigation of an important source of lead exposure suggests examination and re-evaluation of the prevalence of childhood lead poisoning in this country. Ongoing concerns persist about exposure from the Kiteezi landfill in Kampala, the country’s capital. Objectives We determined blood lead distributions among Kampala schoolchildren and identified risk factors for elevated blood lead levels (EBLLs; ≥ 10 μg/dL). Analytical approach Using a stratified, cross-sectional design, we obtained blood samples, questionnaire data, and soil and dust samples from the homes and schools of 163 4- to 8-year-old children representing communities with different risks of exposure. Results The mean blood lead level (BLL) was 7.15 μg/dL; 20.5% of the children were found to have EBLL. Multivariable analysis found participants whose families owned fewer household items, ate canned food, or used the community water supply as their primary water source to have higher BLLs and likelihood of EBLLs. Distance < 0.5 mi from the landfill was the factor most strongly associated with increments in BLL (5.51 μg/dL, p < 0.0001) and likelihood of EBLL (OR = 4.71, p = 0.0093). Dust/soil lead was not significantly predictive of BLL/EBLL. Conclusions Lead poisoning remains highly prevalent among school-age children in Kampala. Confirmatory studies are needed, but further efforts are indicated to limit lead exposure from the landfill, whether through water contamination or through another mechanism. Although African nations are to be lauded for the removal of lead from gasoline, this study serves as a reminder that other sources of exposure to this potent neurotoxicant merit ongoing attention.

    The Neglect of the Global Surgical Workforce: Experience and Evidence from Uganda
    (World journal of surgery, 2008) Ozgediz, Doruk; Galukande, Moses; Mabweijano, Jacqueline; Kijjambu, Stephen; Mijumbi, Cephas; Dubowitz, Gerald; Kaggwa, Samuel; Luboga, Samuel
    Africa’s health workforce crisis has recently been emphasized by major international organizations. As a part of this discussion, it has become apparent that the workforce required to deliver surgical services has been significantly neglected. Methods This paper reviews some of the reasons for this relative neglect and emphasizes its importance to health systems and public health. We report the first comprehensive analysis of the surgical workforce in Uganda, identify challenges to workforce development, and evaluate current programs addressing these challenges. This was performed through a literature review, analysis of existing policies to improve surgical access, and pilot retrospective studies of surgical output and workforce in nine rural hospitals.

    Recasting the role of the surgeon in Uganda: a proposal to maximize the impact of surgery on public health
    (Tropical Medicine & International Health, 2009) Luboga, Samuel; Galukande, Moses; Ozgediz, Doruk
    A growing body of recent evidence supports the essential role of surgical services in improving population health in low-income countries. Nonetheless, access to surgical services in Uganda, as in many low income countries, is severely limited, largely due to constraints in human resources, infrastructure and supplies. To maximize the impact of surgical services on population health in the context of Uganda’s limited surgical workforce, we propose a ‘recasting’ of the role of the surgeon. Traditionally, the surgeon has played primarily a clinical role in patient care. The demands and isolation of this role have limited the ability of the surgeon to tackle health systems issues related to surgery. Now, the clinical and educational role played by surgeons must be redefined, and the surgeon must also assume a greater role in leadership, management and public health advocacy by documenting the unmet need for surgery and the resources required to improve access to care. Policy and incentives for specialist surgeons to spend amounts of time apportioned to these roles should be developed and supported by health care institutions. Political leadership and commitment will be critical to realizing this ideal. Such a model may be applicable to other countries seeking to maximize the impact of surgical services on population health.

    Surgical need among the ageing population of Uganda.
    (African Health Sciences, 2019-03) Tran, Tu M.; Fuller, Anthony T.; Butler, Elissa K.; Muhumuza, Christine; Ssennono, Vincent F.; Vissoci, Joao Ricardo; Makumbi, Fredrick; Chipman, Jeffrey G.; Galukande, Moses; Haglund, Michael M.; Luboga, Samuel
    Background: Uganda’s ageing population (age 50 years and older) will nearly double from 2015 to 2050. HIV/AIDS, diabetes, stroke among other disease processes have been studied in the elderly population. However, the burden of disease from surgi- cally-treatable conditions is unknown. Objectives: To determine the proportion of adults above 50 years with unmet surgical need and deaths attributable to probable surgically-treatable conditions. Methods: A cluster randomized sample representing the national population of Uganda was enumerated. The previously vali- dated Surgeons Overseas assessment of surgical need instrument, a head-to-toe verbal interview, was used to determine any sur- gically-treatable conditions in two randomly-selected living household members. Deaths were detailed by heads of households. Weighted metrics are calculated taking sampling design into consideration and Taylor series linearization was used for sampling error estimation. Results: The study enumerated 425 individuals above age 50 years. The prevalence proportion of unmet surgical need was 27.8% (95%CI, 22.1-34.3). This extrapolates to 694,722 (95%CI, 552,279-857,157) individuals living with one or more surgically treatable conditions. The North sub-region was observed to have the highest prevalence proportion. Nearly two out of five household deaths (37.9%) were attributed to probable surgically treatable causes. Conclusion: There is disproportionately high need for surgical care among the ageing population of Uganda with approximate- ly 700,000 consultations needed.
