RESUMO

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. This study was done to describe the epidemiology and trends of the three common illnesses treated by the CHWs in Bugoye Sub-County in rural Uganda. METHODS: A retrospective review of monthly morbidity data for children less than 5 years of age for the period April 2014-December 2018 for CHWs in rural Bugoye Sub-County in Kasese district, Uganda was done. The total number reviewed was 18,430 records. The data were analysed using STATA version 14. RESULTS: In total male were 50.2% of the sample, pneumonia was the highest cause of illness among the infants (< 1 year), while malaria was the highest among the children 1 year-59 months. Infection with a single illness was the commonest recorded cause of presentation but there were some children recorded with multiple illnesses. All the CHWs were managing the three common illnesses among children under 5 years. The trend of the three common illnesses was changing from malaria to pneumonia being the commonest. Children aged 12-24 months and 25-59 months were at 2.1 times (95% CI 1.7-2.4) and 5.2 times (95% CI 4.6-5.9), respectively, more likely to get malaria but less likely to get pneumonia and diarrhoea. CONCLUSION: Community Health Workers in rural Uganda are contributing significantly to the management of all the three commonest illnesses among under-5 years-old children. The trend of the commonest illness is changing from malaria to pneumonia. Children under 1 year are at a higher risk of getting pneumonia and diarrhoea and at a lower risk of getting malaria.

RESUMO

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. METHODS: A cross-sectional household survey was administered in a rural subcounty in western Uganda during December 2016, using a stratified random sampling approach in villages where iCCM care was available. Households were eligible if the household contained one or more children under 5 years of age. RESULTS: A total of 271 households across 8 villages were included in the final sample. Of these, 39% reported that it took over an hour to reach their preferred health facility, and 73% reported walking to the health facility; 92% stated they had seen a VHW for iCCM care in the past, and 55% had seen a VHW in the month prior to the survey. Of respondents whose households had sought iCCM care, 60% rated their overall experience as "very good" or "excellent," 97% stated they would seek iCCM care in the future, and 92% stated they were "confident" or "very confident" in the VHW's overall abilities. Longer travel time to the household's preferred health facility did not appear to be associated with higher propensity to seek iCCM care or higher overall satisfaction with iCCM care. CONCLUSIONS: In this setting, community usage of and satisfaction with iCCM care for malaria, pneumonia, and diarrhoea appears high overall. Ease of access to facility-based care did not appear to impact the choice to access iCCM care or satisfaction with iCCM care.

RESUMO

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. METHODS: This was a prospective observational study of referrals made by CHWs in 8 villages in rural western Uganda. All patient referrals by CHWs were tracked and health centre registers were reviewed for documentation of completed referrals. Caregivers of referred patients were invited to complete a survey 2-3 weeks after the referral with questions on the CHW visit, referral completion, and the patient's clinical condition. RESULTS: Among 143 total referrals, 136 (94%) caregivers completed the follow-up survey. Reasons for visiting the CHW were fever/malaria in 111 (82%) cases, cough in 61 (45%) cases, and fast/difficult breathing in 25 (18%) cases. Overall, 121 (89%) caregivers reported taking the referred child for further medical evaluation, of whom 102 (75% overall) were taken to the local public health centre. Ninety per cent of reported referral visits were confirmed in health centre documentation. For the 34 caregivers who did not complete referral at the local health centre, the most common reasons were improvement in child's health, lack of time, ease of going elsewhere, and needing to care for other children. Referrals were slightly more likely to be completed on weekdays versus weekends (p = 0.0377); referral completion was otherwise not associated with child's age or gender, caregiver age, or caregiver relationship to child. One village had a lower rate of referral completion than the others. Improvement in the child's health was not associated with completed referral or timing of the referral visit. CONCLUSIONS: A high percentage of children referred to the health centre through iCCM in rural Uganda completed the referral. Barriers to referral completion included improvement in the child's health, time and distance. Interestingly, referral completion at the health centre was not associated with improvement in the child's health. Barriers to referral completion and clinical management at all stages of referral linkages warrant further study.

RESUMO

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. However, referral completion rates vary widely among iCCM programmes and are difficult to monitor. The Bugoye Integrated Community Case Management Initiative (BIMI) is an iCCM programme operating in Bugoye sub-county, Uganda. This case study describes BIMI's experience with monitoring referral completion at Bugoye Health Centre III (BHC), and outlines improvements to be made within iCCM referral systems. METHODS: This study triangulated multiple data sources to evaluate the strengths and gaps in the BIMI referral system. Three quantitative data sources were reviewed: (1) VHW report of referred patients, (2) referral forms found at BHC, and (3) BHC patient records. These data sources were collated and triangulated from January-December 2014. The goal was to determine if patients were completing their referrals and if referrals were adequately documented using routine data sources. RESULTS: From January-December 2014, there were 268 patients referred to BHC, as documented by VHWs. However, only 52 of these patients had referral forms stored at BHC. Of the 52 referral forms found, 22 of these patients were also found in BHC register books recorded by clinic staff. Thus, the study found a mismatch between VHW reports of patient referrals and the referral visits documented at BHC. This discrepancy may indicate several gaps: (1) referred patients may not be completing their referral, (2) referral forms may be getting lost at BHC, and, (3) referred patients may be going to other health facilities or drug shops, rather than BHC, for their referral. CONCLUSIONS: This study demonstrates the challenges of effectively monitoring iCCM referral completion, given identified limitations such as discordant data sources, incomplete record keeping and lack of unique identifiers. There is a need to innovate and improve the ways by which referral compliance is monitored using routine data, in order to improve the percentage of referrals completed. Through research and field experience, this study proposes programmatic and technological solutions to rectify these gaps within iCCM programmes facing similar challenges. With improved monitoring, VHWs will be empowered to increase referral completion, allowing critically ill children to access needed health services.

RESUMO

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. METHODS: A retrospective observational study that examined clinical records for all patients with danger signs evaluated by CHWs from March 2014 to December 2018 was conducted. RESULTS: In total, 229 children aged <5 y had been recorded as having a danger sign during 2014-2018. Of these children, 56% were males with a mean age of 25 (SD 16.9) mo, among whom 78% were referred by the CHWs as per the iCCM protocol. The age category of 12 to 35 mo had the highest numbers of prereferred and referred cases (54% and 46%, respectively). CONCLUSIONS: CHWs play a key role in early symptomatic detection, prereferral treatment and early referral of children aged <5 y. Danger signs among children aged <5 y, if left untreated, can result in death. A high proportion of the children with danger signs were referred as per the iCCM protocol. Continuous CHW training is emphasized to reduce the number of referral cases that are missed. More studies need to focus on children aged 12-35 mo and why they are the most referred category. Policymakers should occasionally revise iCCM guidelines to detail the types of danger signs and how CHWs can address these.

RESUMO

Physician burnout is a major problem that has long been facing our healthcare system. The COVID-19 pandemic has unfortunately deepened this problem and shed the light on the multiple structural shortcomings of our healthcare system that need immediate attention. Demoralization is one of the core features of "physician burnout," which results from a breakdown of genuine physician-patient interaction. A healthcare system that embraces cultural humility, where we find ourselves rewarded for supporting, uplifting, and respecting our patients' diverse voices could pave the way for battling burnout. Unlike cultural competency, which suggests that one should know everything about another's culture (an unfeasible task), cultural humility is a continuum of self-reflection and critique that aims to foster a deep connection between the physician and patient; a connection that sits at the core of the humanistic and multicultural experience of medicine.

RESUMO

OBJECTIVES: Some pediatric institutions have developed adult inpatient services to enable quality care of hospitalized adults. Our objectives were to understand the characteristics of these adult inpatient services in pediatric hospitals, barriers and facilitators to their creation and sustainability, and patient and system needs they addressed. METHODS: An explanatory mixed methods study was conducted using a distribution of an electronic survey followed by targeted semi-structured interviews of directors (or designates) of adult inpatient services in US pediatric hospitals. The survey identified institutional demographics, service line characteristics, and patient populations. An interview guide was created to explore survey findings and facilitators and barriers in the creation of adult inpatient services. Interviews were conducted after survey completion. A codebook was created using an inductive thematic approach and iteratively refined. Final themes were condensed, and illustrative quotes selected. RESULTS: Ten institutions identified as having an adult inpatient service. Service staffing models varied, but all had dually trained internal medicine and pediatrics physicians. All participants voiced their respective pediatric institutions valued that these services filled a clinical care gap for hospitalized adults adding to whole-person care, patient safety, and health system navigation. CONCLUSIONS: Adult inpatient services in pediatric institutions have been present for >15 years. These services address clinical care gaps for adults hospitalized in pediatric institutions and use specialized internal medicine and pediatrics knowledge. Demonstrating return on investment of these services using a traditional fee for service model is a barrier to creation and sustainability.

RESUMO

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. The first cohort of VHWs began providing iCCM care in March 2013, the second cohort in July 2016. PARTICIPANTS: All children receiving iCCM care in 18 430 clinical encounters occurring between April 2014 and December 2018. PRIMARY AND SECONDARY OUTCOME MEASURES: The descriptive primary outcome measure was the proportion of patients receiving overall correct care, defined as adherence to the iCCM protocol for the presenting condition (hereafter quality of care). The analytic primary outcome was change in the odds of receiving correct care over time, assessed using logistic regression models with generalised estimating equations. Secondary outcome measures included a set of binary measures of adherence to specific elements of the iCCM protocol. Preplanned and final measures were the same. RESULTS: Overall, VHWs provided correct care in 74% of clinical encounters. For the first cohort of VHWs, regression modelling demonstrated a modest increase in quality of care until approximately 3 years after their initial iCCM training (OR 1.022 per month elapsed, 95% CI 1.005 to 1.038), followed by a modest decrease thereafter (OR 0.978 per month, 95% CI 0.970 to 0.986). For the second cohort, quality of care was essentially constant over time (OR 1.007 per month, 95% CI 0.989 to 1.025). CONCLUSION: Quality of care was relatively constant over time, though the trend towards decreasing quality of care after 3 years of providing iCCM care requires further monitoring.

RESUMO

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. We obtained clinical records for all iCCM encounters in the same time period. RESULTS: In the video case scenarios, 45% of mock patients received all correct management steps (including all recommended education), while 94% received all critical management steps. Based on the level of data available from record review, 74% of patients in the record review dataset received overall correct management compared to 94% in the video case scenarios. In the case scenarios, VHWs with primary school education performed similarly to those with some or all secondary school education. CONCLUSIONS: The case scenarios produced higher estimates of quality of care than record review. VHWs often omitted recommended health education topics in the case scenarios. Level of formal education did not appear to influence performance in the case scenarios.

RESUMO

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. Trained interviewers observed 36 VHWs reading six mock RDTs each and performing an RDT as part of a larger skills assessment exercise. VHWs read 97% of mock RDTs correctly; of the 36 VHWs, 86% read all six mock RDTs correctly. Most VHWs scored either 12/13 or 13/13 on the RDT checklist (39% and 36%, respectively), with 25% scoring 11/13 or lower. For reading mock RDTs, VHWs in the first group (initial training 4 years before study) read 97% of mock RDTs correctly, whereas those in the second group (initial training 1 year before study) read 96% of mock RDTs correctly; the first group had a mean of 5.83 RDTs read correctly, compared with 5.77 RDTs read correctly in the second group (P = 0.83). For performing an RDT, the first group completed a mean of 12.0 steps correctly, compared with a mean of 12.2 correct steps in the second group (P = 0.60). Overall, VHWs demonstrated proficiency in reading RDTs accurately and performing RDTs according to protocol at least 4 years after initial iCCM training.

RESUMO

OBJECTIVES: To evaluate medical trainees' attitudes toward refugee patients in a refugee host country, and to identify educational needs. METHODS: A 54-question cross-sectional questionnaire was administered to a convenience sample of 81 post-graduate medical trainees at Mbarara Regional Referral Hospital, Uganda, in 2016. Descriptive statistics on medical trainees' attitudes and educational needs regarding care for refugees were calculated. One-way ANOVA was used to assess relationships between an attitude scale and respondent characteristics. Reliability and validity of the survey items and attitude scale were assessed using Cronbach's alpha, item-to-scale correlation, and factor analysis. RESULTS: The mean score on the attitude scale of 2.8 (SD=1.7) indicated positive attitudes toward refugees. All respondents had contact with refugees, and 89% (n=72) reported a need for further training. Many specifically indicated the need for training in use of translators, support personnel, and behavioral health.  Cronbach's alpha values of greater than 0.7 indicated good internal consistency. Item-to-scale correlation and factor analysis validate the use of an attitude scale. ANOVA showed no significant difference between mean attitude scores in gender (F(1,77)=0.11, p=0.7367), country of origin (F(1.78) =0.53, p=0.8723), or year of study (F(4,74) =0.31, p=0.8273). CONCLUSIONS: Medical trainees in Uganda report positive attitudes toward refugees and a need for additional education in refugee care in multiple specific areas. This study piloted the use of an attitude scale for refugee healthcare providers with promising validity and reliability. Use of these questions could inform curriculum development in refugee host countries.

RESUMO

The high cost, complexity and reliance on electricity, specialized equipment and supplies associated with conventional diagnostic methods limit the scope and sustainability of newborn screening for sickle cell disease (SCD) in sub-Saharan Africa and other resource-limited areas worldwide. Here we describe the development of a simple, low-cost, rapid, equipment- and electricity-free paper-based test capable of detecting sickle hemoglobin (HbS) in newborn blood samples with a limit of detection of 2% HbS. We validated this newborn paper-based test in a cohort of 159 newborns at an obstetric hospital in Cabinda, Angola. Newborn screening results using the paper-based test were compared to conventional isoelectric focusing (IEF). The test detected the presence of HbS with 81.8% sensitivity and 83.3% specificity, and identified SCD newborns with 100.0% sensitivity and 70.7% specificity. The use of the paper-based test in a two-stage newborn screening process could have excluded about 70% of all newborns from expensive confirmatory testing by IEF, without missing any of the SCD newborns in the studied cohort. This study demonstrates the potential utility of the newborn paper-based test for reducing the overall cost of screening newborns for SCD and thus increasing the practicality of universal newborn SCD screening programs in resource-limited settings.

RESUMO

An increasing body of evidence indicates that constitutive activation of NF-kappaB contributes to tumorigenesis and inflammation. Ubiquitination and degradation of IkappaB plays an essential role in NF-kappaB activation. Here we describe an in vitro IkappaBalpha ubiquitination assay system in which purified E1, E2, SCF(beta-Trcp1) E3, IkappaBalpha, IKK2, and Ub were used to generate ubiquitinated IkappaBalpha. The ubiquitination of IkappaBalpha is strictly dependent on its phosphorylation by IKK2, as well as the presence of E1, E2, E3, and Ub. The assay was adapted into 384-well plate format in which an antibody against IkappaBalpha was used to capture IkappaBalpha, and the biotinylated ubiquitin attached to IkappaBalpha was detected with europium (Eu)-labeled streptavidin. This assay can be used to discover inhibitors of IkappaBalpha ubiquitination. Such inhibitors would block NF-kappaB activation by stabilizing IkappaB levels in cells and thus provide a new therapeutic approach to NF-kappaB-related human diseases.

RESUMO

p27, an important cell cycle regulator, blocks the G(1)/S transition in cells by binding and inhibiting Cdk2/cyclin A and Cdk2/cyclin E complexes (Cdk2/E). Ubiquitination and subsequent degradation play a critical role in regulating the levels of p27 during cell cycle progression. Here we provide evidence suggesting that both Cdk2/E and phosphorylation of Thr(187) on p27 are essential for the recognition of p27 by the SCF(Skp2/Cks1) complex, the ubiquitin-protein isopeptide ligase (E3). Cdk2/E provides a high affinity binding site, whereas the phosphorylated Thr(187) provides a low affinity binding site for the Skp2/Cks1 complex. Furthermore, binding of phosphorylated p27/Cdk2/E to the E3 complex showed positive cooperativity. Consistently, p27 is also ubiquitinated in a similarly cooperative manner. In the absence of p27, Cdk2/E and Cks1 increase Skp2 phosphorylation. This phosphorylation enhances Skp2 auto-ubiquitination, whereas p27 inhibits both phosphorylation and auto-ubiquitination of Skp2.
