Delivering child health interventions through the private sector in low and middle income countries: challenges, opportunities, and potential next steps.

Universal health coverage requires both the public and private sectors to ensure quality, equity, and efficiency in health systems, say Phyllis Awor and colleague

Using ultrasonography, laboratory blood tests and maternal characteristics to predict Pre-eclampsia and adverse pregnancy outcomes at St. Mary’s Hospital Lacor, Northern Uganda

A thesis submitted to the directorate of Research And Graduate Training in fulfillment of the requirements for the award of a Degree Of Doctor Of Philosophy Of Makerere University.Background: Preeclampsia causes 12% to 19% of maternal deaths in Uganda. Complications include preterm birth, stillbirth and low birth weight. Early diagnosis and timely delivery improve pregnancy outcomes. Nevertheless, due to poor infrastructure in northern Uganda, early prediction and diagnosis with eventual treatment may save lives. Therefore, we set out to predict pre-eclampsia and adverse pregnancy outcomes using maternal history, laboratory characteristics and uterine artery Doppler indices in northern Uganda. Methods: This prospective cohort study recruited 1,285 pregnant mothers at 16-24 weeks. Participants' history, physical findings, blood tests (full haemogram, renal and liver function) and uterine artery Doppler indices were recorded. One thousand four (1,004) enrolled pregnant mothers had complete delivery records. Preeclampsia, preterm birth, stillbirth and low birth weight were the desired outcomes. We built models in RStudio for predicting preeclampsia, preterm birth, stillbirth and low birth weight. Statistical analysis: t-tests, Mann-Whitney tests and Pearson’s chi-square were used to compare means, medians, and proportions, respectively. We calculated incidences of low birth weight at term, pre-eclampsia, preterm birth and stillbirth. We identified from maternal history, physical examination, uterine artery Doppler indices and blood tests, maternal risk factors for preeclampsia, preterm birth, stillbirth and low birthweight at term using the logistic regression models in RStudio. We re-processed the data using the ROSE package to produce synthetic data (test data) to evaluate the (original) model performance and validated the models using K-fold cross-validation. We weighed each variable contribution in the prediction model. Results: The incidence of pre-eclampsia, preterm birth, stillbirth and low birth weight at term were 4.3%, 11.6%, 2.5% and 5.7%, respectively. The predictors of these adverse pregnancy outcomes were Maternal age ≥ 35 years, nulliparity, personal history of preeclampsia, tertiary level of education, BMI ≥ 26.5Kg/m2, diastolic hypertension, bilateral end-diastolic notch, lateral placental location, serum GGT ≥30 IU, serum ALT 12 – 49 IU, white blood cell count ≥ 11,000 cells/µl, lymphocyte count of 800-4000 cells/µl, haemoglobin level ≥ 12.1g/dL and serum ALP <98 IU. The models had a good fit if McFadden's pseudo-R2 was between 0.2–0.4. Maternal history, laboratory tests and uterine artery Doppler sonography predicted pre-eclampsia with 84.9% AUC and McFadden’s pseudo-R2 of 0.30. The variables with weights up to ≥6.0 predicted adverse pregnancy outcomes by ≥60% AUC and ≥ 50% accuracy. Conclusion: The prediction models for preeclampsia had AUC of 71.4% to 84.9%. Since the patients present to prenatal clinics with different predictors, the variable weights adding up to ≥6.0 predicted adverse outcomes by ≥60% AUC. These may help to develop prenatal screening tools for preeclampsia in Uganda. We recommend incorporating the prediction of preeclampsia into prenatal care and strengthening the referral pathways for those found to be at risk.1.

Definitions of severity in treatment seeking studies of febrile illness in children in low and middle income countries: a scoping review

Objectives: Understanding treatment seeking for severe febrile illness (SFI) is methodologically challenging. In this scoping review, we investigate definitions of severe febrile illness in treatment seeking studies on children under 5 years of age in low and middle income countries. We analyze the association of SFI definitions with different concepts of treatment seeking and identify related research gaps. Methods: We searched Pubmed, Scopus and WHOLIS, and screened references of included publications for eligibility. Results: Definitions of SFI had either a biomedical perspective (predominantly in quantitative studies) or a caregiver perspective (predominantly in qualitative studies). In quantitative analyses of treatment seeking, severity was more often conceptualized as a determinant rather than an outcome of a treatment seeking process. The majority of quantitative analyses only included surviving children or did not explicitly mention dead children. Conclusion: Different research questions lead to diverse definitions and concepts of severity and treatment seeking outcomes, which limits the comparability of the available evidence. Systematic exclusion of dead children is likely to bias inferences on the association of treatment seeking and health outcomes of children with SFI in low and middle income countries

Determinants of long term survival of patients initiated on HAART at the AIDS support organization, Uganda

Master of Public Health - MPHIt is well documented that mortality rates have decreased and the survival of HIV and AIDS patients has been prolonged since the introduction of highly active antiretroviral therapy (HAART) in 1996. Although HAART has dramatically improved the prognosis of HIV disease, some HIV patients on HAART still die of HIV related illnesses. It is important to understand what these factors are in order to mitigate the impact on these factors on patient survival and achieve better outcome for these patients. The aim of this study was to determine risk factors for long term survival of patients on HAART in Uganda. Data for 2,244 out of 30,000 clients receiving care and treatment at TASO Entebbe was retrospectively analyzed. TASO Entebbe is a non-governmental HIV clinic that provides care and treatment to HIV positive clients. Long term survival in this case was defined as survival for more than 5 years after initiation on HAART. Logistic regression and survival analysis were conducted. Female clients had a 12% lower risk of death compared to the male clients (AHR=0.88 [CI: 0.443- 0.936]). Clients that had pulmonary TB had 1.3 times higher risk of death compared to clients that did not have pulmonary TB (AHR=1.33 [CI: 1.162-2.733]). Clients initiated at CD4 cell counts less than 250 cells/μl had almost 7 times higher adjusted odds of death compared to those initiated at CD4 cell counts greater than 500 cells/μl (AOR= 6.95 [CI: 2.882-16.744]) and clients initiated at CD4 cell counts between 250 cells/μl and 500 cells/μl almost 3 times higher adjusted odds of death compared to clients initiated at CD4 cell counts greater than 500 cells/μl (AOR 2.56 [CI: 1.004-6.520]). It is recommended that an aggressive HIV testing strategy be put in place to facilitate early identification of HIV positive patients. Early identification would enable early initiation into HAART well before the CD4 cell counts fall below 500 cells/μl. The observed higher risk of mortality amongst men suggests interventions to promote early HIV testing and treatment initiation amongst men. The observed high risk of mortality for patients with pulmonary TB, calls for aggressive TB case finding and treatment of positive in order to reduce the HIV/TB related mortality

A cross-sectional study to identify the distribution and characteristics of licensed and unlicensed private drug shops in rural Eastern Uganda to inform an iCCM intervention to improve health outcomes for children under five years

Introduction: Malaria, pneumonia and diarrhea are leading causes of death in young children in Uganda. Between 50-60% of sick children receive treatment from the private sector, especially drug shops. There is an urgent need to improve quality of care and regulation of private drug shops in Uganda. This study was conducted to determine the distribution, the licensing status and characteristics of drug shops in four sub-districts of Kamuli district. Methods: This study was part of a pre-post cross sectional study that examined the implementation of an integrated Community Case Management (iCCM) intervention for common childhood illness in rural private drug shops in Kamuli District in Eastern Uganda. This mapping exercise used a snowball sampling technique to identify licensed and unlicensed drug shops and collect information about their characteristics. Data were collected using a questionnaire. GPS data were collected for all drug shops. Analysis: Quantitative data were analyzed using SPSS for descriptive statistics. Open ended questions were entered into NVivo 10 and analyzed using thematic analysis strategies. Results: In total, 215 drug shops in 284 villages were located. Of these, 123 (57%) were open and consented to an interview. Only 12 (10%) drug shops were licensed, 93 (76%) were unlicensed, and the licensing status of 18 (15%) was unknown. Most respondents were the owner of the drug shop (88%); most drug sellers reported their qualification as nursing assistants (70%). Drug sellers reported licensing fees and costs of contracting an "in-charge" as barriers to licensing. Nearly all drug shops sold drugs for malaria (91%) and antibiotics (79%)

Integrated community case management in a peri-urban setting: a qualitative evaluation in Wakiso District, Uganda.

Integrated community case management (iCCM) strategies aim to reach poor communities by providing timely access to treatment for malaria, pneumonia and diarrhoea for children under 5 years of age. Community health workers, known as Village Health Teams (VHTs) in Uganda, have been shown to be effective in hard-to-reach, underserved areas, but there is little evidence to support iCCM as an appropriate strategy in non-rural contexts. This study aimed to inform future iCCM implementation by exploring caregiver and VHT member perceptions of the value and effectiveness of iCCM in peri-urban settings in Uganda.A qualitative evaluation was conducted in seven villages in Wakiso district, a rapidly urbanising area in central Uganda. Villages were purposively selected, spanning a range of peri-urban settlements experiencing rapid population change. In each village, rapid appraisal activities were undertaken separately with purposively selected caregivers (n = 85) and all iCCM-trained VHT members (n = 14), providing platforms for group discussions. Fifteen key informant interviews were also conducted with community leaders and VHT members. Thematic analysis was based on the 'Health Access Livelihoods Framework'.iCCM was perceived to facilitate timely treatment access and improve child health in peri-urban settings, often supplanting private clinics and traditional healers as first point of care. Relative to other health service providers, caregivers valued VHTs' free, proximal services, caring attitudes, perceived treatment quality, perceived competency and protocol use, and follow-up and referral services. VHT effectiveness was perceived to be restricted by inadequate diagnostics, limited newborn care, drug stockouts and VHT member absence - factors which drove utilisation of alternative providers. Low community engagement in VHT selection, lack of referral transport and poor availability of referral services also diminished perceived effectiveness. The iCCM strategy was widely perceived to result in economic savings and other livelihood benefits.In peri-urban areas, iCCM was perceived as an effective, well-utilised strategy, reflecting both VHT attributes and gaps in existing health services. Depending on health system resources and organisation, iCCM may be a useful transitional service delivery approach. Implementation in peri-urban areas should consider tailored community engagement strategies, adapted selection criteria, and assessment of population density to ensure sufficient coverage

Poor-quality antimalarials further health inequities in Uganda

Substandard and falsified medications are a major threat to public health, directly increasing the risk of treatment failure, antimicrobial resistance, morbidity, mortality and health expenditures. While antimalarial medicines are one of the most common to be of poor quality in low- and middle-income countries, their distributional impact has not been examined. This study assessed the health equity impact of substandard and falsified antimalarials among children under five in Uganda. Using a probabilistic agent-based model of paediatric malaria infection (Substandard and Falsified Antimalarial Research Impact, SAFARI model), we examine the present day distribution of the burden of poor-quality antimalarials by socio-economic status and urban/rural settings, and simulate supply chain, policy and patient education interventions. Patients incur US$26.1 million (7.8$2.3 million (9.1%) in direct costs and $23.8 million (7.7$2.9 million to the government. The burden of the health and economic impact of malaria and poor-quality antimalarials predominantly rests on the poor (concentration index -0.28) and rural populations (98%). The number of deaths among the poorest wealth quintile due to substandard and falsified antimalarials was 12.7 times that of the wealthiest quintile, and the poor paid 12.1 times as much per person in out-of-pocket payments. Rural populations experienced 97.9% of the deaths due to poor-quality antimalarials, and paid 10.7 times as much annually in out-of-pocket expenses compared with urban populations. Our simulations demonstrated that interventions to improve medicine quality could have the greatest impact at reducing inequities, and improving adherence to antimalarials could have the largest economic impact. Substandard and falsified antimalarials have a significant health and economic impact, with greater burden of deaths, disability and costs on poor and rural populations, contributing to health inequities in Uganda

A Cluster Randomised Trial Introducing Rapid Diagnostic Tests into Registered Drug Shops in Uganda: Impact on Appropriate Treatment of Malaria

Background: Inappropriate treatment of malaria is widely reported particularly in areas where there is poor access to health facilities and self-treatment of fevers with anti-malarial drugs bought in shops is the most common form of care-seeking. The main objective of the study was to examine the impact of introducing rapid diagnostic tests for malaria (mRDTs) in registered drug shops in Uganda, with the aim to increase appropriate treatment of malaria with artemisinin-based combination therapy (ACT) in patients seeking treatment for fever in drug shops. Methods: A cluster-randomized trial of introducing mRDTs in registered drug shops was implemented in 20 geographical clusters of drug shops in Mukono district, central Uganda. Ten clusters were randomly allocated to the intervention (diagnostic confirmation of malaria by mRDT followed by ACT) and ten clusters to the control arm (presumptive treatment of fevers with ACT). Treatment decisions by providers were validated by microscopy on a reference blood slide collected at the time of consultation. The primary outcome was the proportion of febrile patients receiving appropriate treatment with ACT defined as: malaria patients with microscopically-confirmed presence of parasites in a peripheral blood smear receiving ACT or rectal artesunate, and patients with no malaria parasites not given ACT. Findings: A total of 15,517 eligible patients (8672 intervention and 6845 control) received treatment for fever between January-December 2011. The proportion of febrile patients who received appropriate ACT treatment was 72·9% versus 33·7% in the control arm; a difference of 36·1% (95% CI: 21·3 – 50·9), p<0·001. The majority of patients with fever in the intervention arm accepted to purchase an mRDT (97·8%), of whom 58·5% tested mRDT-positive. Drug shop vendors adhered to the mRDT results, reducing over-treatment of malaria by 72·6% (95% CI: 46·7– 98·4), p<0·001) compared to drug shop vendors using presumptive diagnosis (control arm). Conclusion: Diagnostic testing with mRDTs compared to presumptive treatment of fevers implemented in registered drug shops substantially improved appropriate treatment of malaria with ACT

Impact of mass media campaigns on knowledge of malaria prevention measures among pregnant mothers in Uganda: a propensity score-matched analysis

Background: Uganda grapples with a considerable malaria burden, reporting prevalence rates of over 33% in some regions. To address this, the Uganda Ministry of Health employs audiovisual platforms for disseminating malaria prevention messages. However, the impact of these messages on pregnant women’s knowledge of malaria prevention remains insufficiently explored. This paper therefore emphasizes the influence of audiovisual messages on the knowledge of malaria prevention measures among pregnant women in Uganda. Methods: Secondary data obtained from the Uganda Malaria Indicator Survey (MIS) 2018–2019 was used for this analysis. Women aged 15–49 were included in the study. A total of 8868 women were selected using a two-stage sample design. The two stages of selection included clusters and households. Women who were currently pregnant were included in the study, resulting in a weighted sample of 721 women. Propensity score-matched analysis was used to evaluate the impact of access to malaria messages on knowledge of prevention measures. Results: The study revealed that 39% [95% CI 34.0–44.2] of pregnant women were exposed to malaria messages before the survey. Those exposed had a 17.2% higher knowledge [ATT = 0.172; 95% CI 0.035–0.310] of using mosquito nets for prevention compared to those unexposed. Among women exposed, radios accounted for most form of access to mass media campaigns [64.8, 95% CI 57.0–71.8] followed by interpersonal communication [45.0, 95% CI 37.6–52.6], community health workers [38.8, 95% CI 29.6–48.8], community events [21.4, 95% CI 15.8–28.3], and social mobilization [18.3, 95% CI 12.7–25.8]. Conclusion: Results highlight the importance of radios in spreading important malaria prevention messages to pregnant women. Being exposed to these messages is linked to increased awareness and knowledge about the proper use of insecticide-treated bed nets (ITNs) for preventing malaria. This finding underscores the importance of evaluating different channels for mass media campaigns to ensure the effective delivery of information about malaria prevention to the intended audiences

Obstacles to family planning use among rural women in Atiak Health Center IV, Amuru District, northern Uganda

Background: Uganda’s rapid population growth (3.2%) since 1948 has placed more demands on health sector and lowered living standard of Ugandans resulting into 49% of people living in acute poverty especially in post conflict Northern Uganda. The population rise was due to low use of contraceptive methods (21% in rural areas and 43% in urban areas) and coupled with high unmet need for family planning (41%). This indicated poor access to reproductive health services. Effective use of family planning could reduce the rapid population growth.Objective: To determine obstacles to family planning use among rural women in Northern Uganda.Design: A descriptive cross-sectional analytical study.Setting: Atiak Health Centre IV, Amuru District, rural Northern Uganda.Subjects: Four hundred and twenty four females of reproductive ages were selected from both Inpatient and Outpatient Departments of Atiak Health Centre IV.Results: There was high level of awareness 418 (98.6%), positive attitude 333 (78.6%) and fair level of utilisation 230 (54.2%) of family planning. However, significant obstacles to family planning usage included; long distance to Health facility, unavailability of preferred contraceptive methods, absenteeism of family planning providers, high cost of managing side effects, desire for big family size ,children dying less than five years old, husbands forbidding women from using family planning and lack of community leaders’ involvement in family planning programme.Conclusions: In spites of the high level of awareness, positive attitude, and free family planning services, there were obstacles that hindered family planning usage among these rural women. However, taking services close to people, reducing number of children dying before their fifth birthday, educating men about family planning, making sure family planning providers and methods are available, reducing cost of managing side effects and involving community leaders will improve utilisation of family planning and thus reduce the rapid population growth and poverty
