A cross-sectional study of point-of-care lactate testing in integrated community care management (ICCM) for children with acute respiratory illness in rural uganda.

Background: Integrated community case management (iCCM) programs leverage lay village health workers (VHWs) to carry out the initial evaluation of children with common conditions including malaria, pneumonia and diarrhea. Therefore, it is imperative that VHWs are able to identify children who are critically ill and require referral to a health facility. Elevated venous lactate levels have been associated with severe illness and adverse health outcomes, including death.

Advancing mHealth Research in Low-Resource Settings: Young Women's Insights and Implementation Challenges with Wearable Smartwatch Devices in Uganda.

In many regions globally, including low-resource settings, there is a growing trend towards using mHealth technology, such as wearable sensors, to enhance health behaviors and outcomes. However, adoption of such devices in research conducted in low-resource settings lags behind use in high-resource areas. Moreover, there is a scarcity of research that specifically examines the user experience, readiness for and challenges of integrating wearable sensors into health research and community interventions in low-resource settings specifically.

Cost-effectiveness of village health worker-led integrated community case management (iCCM) versus health facility based management for childhood illnesses in rural southwestern Uganda.

Background: In Uganda, village health workers (VHWs) manage childhood illness under the integrated community case management (iCCM) strategy. Care is provided for malaria, pneumonia, and diarrhoea in a community setting. Currently, there is limited evidence on the cost-effectiveness of iCCM in comparison to health facility-based management for childhood illnesses.

Promptness in seeking treatment from Village Health workers for children under five years with malaria, diarrhoea and pneumonia in rural southwestern Uganda.

Background: Village Health Workers (VHWs) in Uganda provide treatment for the childhood illness of malaria, pneumonia, and diarrhoea through the integrated community case management (iCCM) strategy. Under the strategy children under five years receive treatment for these illnesses within 24 h of onset of illness. This study examined promptness in seeking treatment from VHWs by children under five years with malaria, pneumonia, and diarrhoea in rural southwestern Uganda.

Management of children with danger signs in integrated community case management care in rural southwestern Uganda (2014-2018).

Background: In integrated community case management (iCCM) care, community health workers (CHWs) provide home-based management of fever, diarrhea and fast breathing for children aged <5 y. The iCCM protocol recommends that children with danger signs for severe illness are referred by CHWs to health facilities within their catchment area. This study examines the management of danger signs by CHWs implementing iCCM in a rural context.

Contribution of community health workers to the treatment of common illnesses among under 5-year-olds in rural Uganda.

Background: The control of malaria, pneumonia, and diarrhoea is important for the reduction in morbidity and mortality among children under 5 years. Uganda has adopted the Integrated Community Case Management strategy using Community Health Workers (CHWs) to address this challenge. The extent and trend of these three conditions managed by the CHWs are not well documented.

Long-term quality of integrated community case management care for children in Bugoye Subcounty, Uganda: a retrospective observational study.

Objective: Integrated community case management (iCCM) of childhood illness in Uganda involves protocol-based care of malaria, pneumonia and diarrhoea for children under 5 years old. This study assessed volunteer village health workers' (VHW) ability to provide correct iCCM care according to the national protocol and change in their performance over time since initial training.

Setting: VHWs affiliated with the Ugandan national programme provide community-based care in eight villages in Bugoye Subcounty, a rural area in Kasese District.

Measles outbreak in Western Uganda: a case-control study.

Background: Measles outbreaks are prevalent throughout sub-Saharan Africa despite the preventive measures like vaccination that target under five-year-old children and health systems strengthening efforts like prioritizing the supply chain for supplies. Measles immunization coverage for Kasese district and Bugoye HC III in 2018 was 72 and 69%, respectively. This coverage has been very low and always marked red in the Red categorization (below the national target/poor performing) on the national league table indicators.

Usage of and satisfaction with Integrated Community Case Management care in western Uganda: a cross-sectional survey.

Background: In some areas of Uganda, village health workers (VHW) deliver Integrated Community Case Management (iCCM) care, providing initial assessment of children under 5 years of age as well as protocol-based treatment of malaria, pneumonia, and diarrhoea for eligible patients. Little is known about community perspectives on or satisfaction with iCCM care. This study examines usage of and satisfaction with iCCM care as well as potential associations between these outcomes and time required to travel to the household's preferred health facility.

Dengue in Western Uganda: a prospective cohort of children presenting with undifferentiated febrile illness.

Background: The spatial distribution and burden of dengue in sub-Saharan Africa remains highly uncertain, despite high levels of ecological suitability. The goal of this study was to describe the epidemiology of dengue among a cohort of febrile children presenting to outpatient facilities located in areas of western Uganda with differing levels of urbanicity and malaria transmission intensity.

Methods: Eligible children were first screened for malaria using rapid diagnostic tests.

Assessing Village Health Workers' Ability to Perform and Interpret Rapid Diagnostic Tests for Malaria 4 Years after Initial Training: A Cross-Sectional Study.

Village health workers (VHWs) in Bugoye subcounty, Uganda, provide integrated community case management (iCCM) care to children younger than 5 years for malaria, pneumonia, and diarrhea. We assessed the longevity of VHWs' skills in performing and reading malaria rapid diagnostic tests (RDTs) 4 years after initial training, comparing VHWs who had completed initial iCCM training 1 year before the study with VHWs who had completed training 4 years before the study. Both groups received quarterly refresher trainings.

A cross-sectional study comparing case scenarios and record review to measure quality of Integrated Community Case Management care in western Uganda.

Background: In Integrated Community Case Management (iCCM), village health workers (VHW) assess and treat malaria, pneumonia and diarrhea using a clinical algorithm. Study objectives included: 1) Compare VHWs' performance on case scenario exercises to record review data; 2) assess impact of formal education on performance in the case scenario exercises.

Methods: 36 VHWs in Bugoye Subcounty, Uganda completed the case scenarios exercise, which included video case scenarios and brief oral case vignettes, between July 2017 and February 2018.

Prevalence of Molecular Markers of Antimalarial Drug Resistance across Altitudinal Transmission Zones in Highland Western Uganda.

We explored spatial variation in the prevalence of established molecular markers of antimalarial resistance across a geographically diverse, highland region of western Uganda. We identified CQ resistance transporter 76T mutations in all pools, but there was no evidence of spatial differences across village-based strata defined by either altitude or river valley. In contrast, we identified a significant inverse association between altitude and the prevalence of multidrug resistance 1 mutations with the largest proportion of Y184F mutations observed in the low-elevation, high-transmission villages.

Completion of community health worker initiated patient referrals in integrated community case management in rural Uganda.

Background: Uganda has sought to address leading causes of childhood mortality: malaria, pneumonia and diarrhoea, through integrated community case management (iCCM). The success of this approach relies on community health worker (CHW) assessment and referral of sick children to a nearby health centre. This study aimed to determine rates of referral completion in an iCCM programme in rural Uganda.

Private sector drug shops frequently dispense parenteral anti-malarials in a rural region of Western Uganda.

Background: Malaria is a leading cause of paediatric morbidity and mortality in Uganda. More than half of febrile children in rural areas initially seek care at private clinics and drug shops. These shops are generally unregulated and the quality of clinical care is variable, with the potential for misdiagnosis and the development of drug resistance.

Who Stays and Who Goes: Predictors of Admission among Patients Presenting with Febrile Illness and a Positive Malaria Rapid Diagnostic Test in a Rural Ugandan Health Center.

Not much is known about clinical decision-making in rural, low-resource settings regarding fever, a common reason for presentation to care. In this prospective cohort study of patients presenting with febrile illness to a rural Ugandan health center, we examined demographic and clinical factors predictive of an initial disposition of inpatient admission after clinical evaluation, but before laboratory testing. We then assessed the association of laboratory results and system factors with a change between initial and final disposition plans.

Reuse of malaria rapid diagnostic tests for amplicon deep sequencing to estimate Plasmodium falciparum transmission intensity in western Uganda.

Molecular techniques are not routinely employed for malaria surveillance, while cross-sectional, community-based parasite surveys require significant resources. Here, we describe a novel use of malaria rapid diagnostic tests (RDTs) collected at a single facility as source material for sequencing to esimtate malaria transmission intensity across a relatively large catchment area. We extracted Plasmodium falciparum DNA from RDTs, then amplified and sequenced a region of the apical membrane antigen 1 (pfama1) using targeted amplicon deep sequencing.

Quality of care in integrated community case management services in Bugoye, Uganda: a retrospective observational study.

Background: Village health workers (VHWs) in five villages in Bugoye subcounty (Kasese District, Uganda) provide integrated community case management (iCCM) services, in which VHWs evaluate and treat malaria, pneumonia, and diarrhoea in children under 5 years of age. VHWs use a "Sick Child Job Aid" that guides them through the evaluation and treatment of these illnesses. A retrospective observational study was conducted to measure the quality of iCCM care provided by 23 VHWs in 5 villages in Bugoye subcounty over a 2-year period.

Anemia was an Uncommon Complication of Severe Malaria in a High-Transmission Rural Area of Western Uganda.

The clinical epidemiology of severe malaria among patients presenting to peripheral health centers has not been well described. We conducted a prospective, observational cohort study to describe the epidemiology and clinical manifestations of severe malaria in a highland area of declining transmission intensity in Western Uganda. Individuals presenting with a history of fever were screened with a malaria rapid diagnostic test (RDT).

Use of a Dual-Antigen Rapid Diagnostic Test to Screen Children for Severe Plasmodium falciparum Malaria in a High-Transmission, Resource-Limited Setting.

Background: In rural areas, many patients with malaria seek care at peripheral health facilities or community case management programs. While this strategy is effective for the management of uncomplicated malaria, severe malaria necessitates prompt detection and referral to facilities with adequate resources.

Methods: In this prospective, observational cohort study, we assessed the accuracy of a dual-band (histidine-rich protein-2/pan-lactate dehydrogenase [HRP2/pLDH]) rapid diagnostic test (RDT) to differentiate uncomplicated from severe malaria.

Improving the Specificity of Plasmodium falciparum Malaria Diagnosis in High-Transmission Settings with a Two-Step Rapid Diagnostic Test and Microscopy Algorithm.

Poor specificity may negatively impact rapid diagnostic test (RDT)-based diagnostic strategies for malaria. We performed real-time PCR on a subset of subjects who had undergone diagnostic testing with a multiple-antigen (histidine-rich protein 2 and -lactate dehydrogenase pLDH [HRP2/pLDH]) RDT and microscopy. We determined the sensitivity and specificity of the RDT in comparison to results of PCR for the detection of malaria.

Severe Flooding and Malaria Transmission in the Western Ugandan Highlands: Implications for Disease Control in an Era of Global Climate Change.

Background:  There are several mechanisms by which global climate change may impact malaria transmission. We sought to assess how the increased frequency of extreme precipitation events associated with global climate change will influence malaria transmission in highland areas of East Africa.

Methods:  We used a differences-in-differences, quasi-experimental design to examine spatial variability in the incidence rate of laboratory-confirmed malaria cases and malaria-related hospitalizations between villages (1) at high versus low elevations, (2) with versus without rivers, and (3) upstream versus downstream before and after severe flooding that occurred in Kasese District, Western Region, Uganda, in May 2013.

Monitoring iCCM referral systems: Bugoye Integrated Community Case Management Initiative (BIMI) in Uganda.

Background: In Uganda, over half of under-five child mortality is attributed to three infectious diseases: malaria, pneumonia and diarrhoea. Integrated community case management (iCCM) trains village health workers (VHWs) to provide in-home diagnosis and treatment of these common childhood illnesses. For severely ill children, iCCM relies on a functioning referral system to ensure timely treatment at a health facility.
