Health service delay among pulmonary tuberculosis patients presenting to a National Referral Hospital, Kampala, Uganda: a cross sectional study
Introduction: Delay in the diagnosis of pulmonary tuberculosis (PTB) is common in many countries in Sub-Saharan Africa. Timely diagnosis of active tuberculosis is crucial in minimizing morbidity and mortality in the community as well as nosocomial transmission in health care facilities. This study aimed at determining factors associated with health service delay in the diagnosis and initiation of treatment among new PTB patients presenting to the National Referral Hospital-Mulago.Methods: This was a cross-sectional study among eligible new PTB patients presenting at the National referral TB treatment center Mulago hospital, between March to May 2009. The patients were consecutively recruited and interviewed using a semi-structured questionnaire to assess socio- demographic and health service factors. Multivariate logistic regression using odds ratios and 95% confidence intervals was done.Results: Two hundred and sixty six newly diagnosed PTB patients were enrolled, of which 65.4% experienced health systems delay. The median health service delay was 9days (IQR=8-19). Factors associated with health service delay were: 1n-patient (OR= 4.68, 95% CI: 1.91-11.45), secondary as highest level of education attained (OR= 3.56, 95% CI: 1.18-10.74), primary as highest level of education attained (OR= 6.70, 95% CI: 2.13-21.02), presence of fever (OR= 3.28, 95% CI: 1.05-10.79), and patient delay at health facility (OR= 5.01, 95% CI: 1.33-18.9). Conclusion: The study found a significant proportion of Health service delay among pulmonary tuberculosis patients presenting at the referral hospital. Being an in-patient and having fever as a symptom of tuberculosis needs further attention in order to have timely diagnosis. There is need for awareness on TB especially that most of the TB symptoms present like other febrile illnesses such as malaria and needs consideration when patients present to a health facility.Key words: Tuberculosis, health service delay, treatment delay, diagnostic delay, pulmonary tuberculosi
Key factors affecting performance of biogas latrines in urban informal areas: Case of Kampala and Nairobi, East Africa
Large scale application of biogas latrine technology in developing countries faces technical, socioeconomic and financial challenges. As a result, harnessing its full potential has not been realized. This study examined variables describing the design, construction, operation and maintenance of nineteen biogas latrines in relation to their performance in Kampala and Nairobi, based on survey and field observations. Pre-tested questionnaires were administered to users, owners and construction technicians/masons of the biogas latrines. Field observations were also undertaken to assess physical conditions of the biogas latrines. Principal component analysis was then used to establish correlation between variables of design, construction, operation and maintenance in relation to the performance of biogas latrines in terms of burning hours in a day. The design types of all the studied biogas latrine digesters were found to be of fixed dome. Co-digestion of human excreta and cow dung increased the number of biogas burning hours in a day from 0.5 to 1.1. The findings also show that the performance of the biogas latrines was influenced by six of the variables examined describing construction, operation and maintenance: skills of masons, use of standards in construction, training of users on operation and maintenance aspects, number of users/owners and their motivation for installation of biogas plants and physical conditions of the biogas latrines. This implies that the use of skilled masons, comprehensive training of users on operation and maintenance aspects and use of cosubstrates are key variables for optimal performance of biogas latrines.Key words: Biogas latrines, Kampala, Nairobi, performance
Development and utilization of a decision support tool for the optimization of fertilizer application in smallholder farms in Uganda
This paper presents the development and pilot of the Fertilizer Optimization Tool (FOT), a decision support tool for use by extension agents in advising smallholder farmers in Uganda in applying optimum (rather than maximum) fertilizer by considering the farmers’ financial abilities. The FOT is made up of three components which includes, the optimizer tool, the nutrient substitution table, and a fertilizer calibration tool. The FOT was developed using field trial data collected on specific agro-ecological zones and mapped using global positioning systems in 13 Sub-Saharan Africa countries. The FOT provides site- and farmer-specific fertilizer recommendations, providing both economic and environmental benefits. Results are based on a survey of 241 households, 57 technical personnel and tracking of 33 FOT users over a 3-season period. Results show a progressive shift in farmers’ attitude towards the value of fertilizer. More FOT users (71%) disagreed with the statement that fertilizers destroy soils, compared with non-FOT users (52%). Crop yields (tons/ha) were significantly higher for crops receiving fertilizers compared to those not. While it is generally accepted that using fertilizer improves crop response and achieves better yields, the value of FOT was reported in terms of rationalization of investment by farmers. The average seasonal investment was approx. $43, giving a return on investment of over 107%. Given the evidence generated from Uganda, there is a need for considering out scaling the FOT technology to other countries in Africa, which are faced with the same challenges of low fertilizer use among smallholder farmers. Using the mobile FOT app provides a further cost-effective opportunity to out scale the approach to benefit more smallholder farmers in sub-Saharan Africa. Further development of the FOT is suggested, particularly in the wake of increased focus on multi-nutrient fertilizer blends, and the need to adjust for soil PH, moisture, and long-term impacts of nutrient substitution.

Outbreak of Marburg hemorrhagic fever among miners in Kamwenge and Ibanda Districts, Uganda, 2007
Marburg hemorrhagic fever was detected among 4 miners in Ibanda District, Uganda, from June through September, 2007. Infection was likely acquired through exposure to bats or bat secretions in a mine in Kamwenge District, Uganda, and possibly human-to-human transmission between some patients. We describe the epidemiologic investigation and the health education response
Modelling study of the ability to diagnose acute rheumatic fever at different levels of the Ugandan healthcare system.
OBJECTIVE: To determine the ability to accurately diagnose acute rheumatic fever (ARF) given the resources available at three levels of the Ugandan healthcare system. METHODS: Using data obtained from a large epidemiological database on ARF conducted in three districts of Uganda, we selected variables that might positively or negatively predict rheumatic fever based on diagnostic capacity at three levels/tiers of the Ugandan healthcare system. Variables were put into three statistical models that were built sequentially. Multiple logistic regression was used to estimate ORs and 95% CI of predictors of ARF. Performance of the models was determined using Akaike information criterion, adjusted R2, concordance C statistic, Brier score and adequacy index. RESULTS: A model with clinical predictor variables available at a lower-level health centre (tier 1) predicted ARF with an optimism corrected area under the curve (AUC) (c-statistic) of 0.69. Adding tests available at the district level (tier 2, ECG, complete blood count and malaria testing) increased the AUC to 0.76. A model that additionally included diagnostic tests available at the national referral hospital (tier 3, echocardiography, anti-streptolysin O titres, erythrocyte sedimentation rate/C-reactive protein) had the best performance with an AUC of 0.91. CONCLUSIONS: Reducing the burden of rheumatic heart disease in low and middle-income countries requires overcoming challenges of ARF diagnosis. Ensuring that possible cases can be evaluated using electrocardiography and relatively simple blood tests will improve diagnostic accuracy somewhat, but access to echocardiography and tests to confirm recent streptococcal infection will have the greatest impact
Menstrual health intervention and school attendance in Uganda (MENISCUS-2): a pilot intervention study.
OBJECTIVES: Achieving good menstrual health and hygiene (MHH) is a public health challenge and there is little evidence to inform interventions. The aim of this study was to pilot test an intervention to improve MHH and school attendance in Uganda, in preparation for a future cluster-randomised trial. DESIGN: Longitudinal study with pre-post evaluation of a pilot intervention. SETTING: Two secondary schools in Entebbe, Uganda. PARTICIPANTS: Of the 473 eligible students in secondary 2 (S2) at baseline, 450 (95.1%; 232 girls and 218 boys) consented/assented. 369 students (188 girls; 81.0%; and 181 boys; 83.0%) participated in the endline survey. INTERVENTION: The intervention comprised training teachers to improve delivery of government guidelines for puberty education, training in use of a menstrual kit and pain management, a drama skit, provision of analgesics and improvements to school water and sanitation hygiene facilities. PRIMARY AND SECONDARY OUTCOME MEASURES: Feasibility and acceptability of delivering the intervention. Baseline and endline quantitative surveys were conducted, with qualitative interviews conducted at endline. School attendance was assessed using self-completed daily diaries among a nested cohort of 100 female students. RESULTS: There were high levels of uptake of the individual and behavioural intervention components (puberty education, drama skit, menstrual hygiene management (MHM) kit and pain management). The proportion of girls reporting anxiety about next period decreased from 58.6% to 34.4%, and reported use of effective pain management increased from 76.4% to 91.4%. Most girls (81.4%) reported improved school toilet facilities, which improved their comfort managing menstruation. The diary data and qualitative data indicated a potential intervention impact on improving menstrual-related school absenteeism. CONCLUSIONS: The pilot study showed that the multicomponent MHM intervention was acceptable and feasible to deliver, and potentially effective in improving menstruation knowledge and management. A cluster-randomised trial is needed to evaluate rigorously the intervention effects on MHM and school attendance. TRIAL REGISTRATION NUMBER: NCT04064736; Pre-results

Assessing the effectiveness of a comprehensive menstrual health intervention program in Ugandan schools (MENISCUS): process evaluation of a pilot intervention study.
BACKGROUND: Poor menstrual health and hygiene (MHH) is a globally recognised public health challenge. A pilot study of an MHH intervention was conducted in two secondary schools in Entebbe, Uganda, over 9 months. The intervention included five components delivered by the implementing partner (WoMena Uganda) and the research team: (i) training teachers to implement government guidelines for puberty education, (ii) a drama skit to reduce stigma about menstruation, (iii) training in use of a menstrual kit (including re-usable pads), (iv) guidance on pain relief methods including provision of analgesics and (v) improvements to school water, sanitation and hygiene (WASH) facilities. The aim of the process evaluation was to examine implementation, context and possible causal pathways. METHODS: We collected information on fidelity, dose, reach, acceptability, context and mechanisms of impact using (i) quantitative survey data collected from female and male students in year 2 of secondary school (ages 13-21; 450 at the baseline and 369 at endline); (ii) qualitative data from 40 in-depth interviews with parents, teachers and female students, and four focus group discussions with students, stratified by gender; (iii) data from unannounced visits checking on WASH facilities throughout the study; and (iv) routine data collected as part of the implementation. Quantitative data were used primarily to assess fidelity, dose and reach. Qualitative data were used primarily to assess acceptability, context and possible mechanisms. RESULTS: Both schools received all intervention elements that were delivered by the research team and implementing partner. The drama skit, menstrual kit and pain management intervention components were delivered with fidelity. Intervention components that relied on school ownership (puberty education training and WASH improvements) were not fully delivered. Overall, the intervention was acceptable to participants. Multilevel contextual factors including schools' social and physical environment, and family, cultural and social factors influenced the acceptability of the intervention in the school setting. The intervention components reinforced one another, as suggested in our theoretical framework. CONCLUSION: The intervention was feasible to deliver and acceptable to the schools and students. We propose a full-scale cluster-randomised trial to evaluate the intervention, adding a school-based MHH leadership group to address issues with school ownership.
