    Health System Analysis of Diabetes and Diabetic Retinopathy Services in Nigeria – The Case of Akwa Ibom State
    (2018) Samuel, Stephen Maduabuchi; Geneau, Robert; Mpyet, Caleb
    This research project, undertaken for a MPH dissertation investigated and analysed the situation of diabetes and diabetic retinopathy services and management systems in four (4) government hospitals in Akwa Ibom State Nigeria using the World Health Organisation (WHO) Tool for the Assessment of Diabetic Retinopathy and Diabetes Management Systems (TADDS). Part A is the research protocol, which explains the background and the key components of this research study. This is a cross sectional descriptive case study involving primary data collection. We conducted the case study using the WHO TADDS to survey health personnel involved in the management of diabetes mellitus (DM) and diabetic retinopathy (DR) in four (4) government hospitals in Akwa Ibom State. Concurrently, semi-structured interviews were conducted with key informants to investigate and analyse the situation of DM and DR services in Akwa Ibom State in Nigeria. Part B is a structured literature review of published articles, online reports, and summaries related to DR. It covers the review of scientific evidence (clinical overview) about the aetiology and prevention of DR and the known risk factors; the review of epidemiological evidence on DM and DR globally and in sub-Saharan Africa (SSA); and the review of the evidence on effectiveness and cost-effectiveness of public health and health system interventions for the prevention and management of DR. Part C is the journal-ready manuscript. In this part, the format of the journal Ophthalmic Epidemiology was used to present the research project and its main findings. Part D contains all the relevant appendices used during the research project.

    Prevalence of trachoma and risk factors for disease in Benue State, Nigeria
    (2018) Tagoh, Selassie; Mpyet, Caleb
    Background: Trachoma is a common contagious bacterial eye infection caused by Chlamydia trachomatis serovariants A, B, Ba or C. It is the leading infectious cause of blindness worldwide and is responsible for about 3% of global blindness. World Health Organization (WHO) reports suggest that of the 2.2 million people who have been rendered visually impaired worldwide by trachoma, 1.2 million are irreversibly blind while an additional 7.3 million people are suffering from trachomatous trichiasis (TT) and are at risk of developing blindness. According to WHO 2007 reports, globally about 84 million people suffer from active trachoma while an estimated 299 million people still live in trachoma endemic districts. In order to eliminate trachoma as a public health problem, The Global Trachoma Mapping Project (GTMP) was initiated on 23 July 2012 as a first step in generating population-level prevalence estimates of the disease so as to determine the need for intervention. Between 2013 and 2015, the GTMP mapped suspected endemic districts including Benue state of Nigeria. This current study took advantage of this data to generate prevalence information on Trachomatous inflammation Follicular (TF) and Trichiasis for Benue state and to describe the some of the household risk factors associated with the disease. The thesis is structured in three parts 0(Preamble), A (Protocol), B (Literature Review), C (Article) and D (Appendix). Methods: A two-stage cluster random sampling technique was utilized in a population based prevalence survey to generate estimates for TF and Trichiasis. Results: Overall unadjusted prevalence of TF among persons 1-9 years was 2.00% (95% CI: 1.20 – 2.98) and that of trichiasis among persons ≥15 years was 0.11% (95% CI 0.06 – 0.12). Trichiasis was more prevalent among adult women 0.05% (95% CI: 0.03 – 0.07) compared to males 0.03 % (95% CI: 0.02 – 0.05), (p=0.13). LGA-level prevalence of TF and Trichiasis among persons 1-9 years and persons ≥15 years ranged from 0.30% (95% CI: 0.1–0.5) to 5.30% (95% CI: 3.30–7.70) and 0.00% to 0.35% (95% CI: 0.12–0.50) respectively. Two LGAs had trichiasis prevalence above 0.2%. TF prevalence was between 5% and 9.9% in 2 LGAs. The common risk factors identified included age, sex, inaccessibility to water and latrine facility. Adults ≥15 years were 8.94(95%CI: 2.79 – 29.64) times more likely to have trichiasis compared to persons between 1-9 years of age. Conclusion: Trachoma was found to be a public health problem in 3 LGAs of Benue state. One round of mass antibiotic distribution will be required in 2 LGAs. With an estimated trichiasis backlog of 1,064, about 173 individuals with trichiasis needed to be managed to reduce the prevalence to less than the elimination threshold.
