Barriers and facilitators to implementing advanced HIV disease screening at a secondary referral hospital -Malawi: a convergent parallel study.

BACKGROUND: Malawi continues to register HIV/AIDS mortality despite increased expansion of ART services and as well as advanced HIV screening as outlined in the 2020 -2025 Malawi National HIV Strategic Plan (NSP). This study aimed to explore factors influencing the implementation of the advanced HIV disease (AHD) screening package at Rumphi District Hospital, Malawi. METHODS: We conducted a mixed method, convergent study at a secondary referral hospital with 8 659 clients on ART. Guided by a consolidated framework for implementation research (CFIR) we conducted semi-structured Interviews with healthcare professionals, purposively selected from various key departments that were actively involved in AHD screening. Transcripts were organized and coded using NVivo 12 software with thematically predefined CFIR constructs. Newly HIV-positive client records extracted from ART cards (July -Dec, 2021) were analyzed using STATA 14 software. RESULTS: One hundred one ART records met inclusion criteria for review and analysis of which 60% (n = 61) of the newly diagnosed HIV clients had no documented results for CD4 Cell count. Barriers to AHD screening emerged from four major CFIR constructs: intervention complexity, communication, availability of resources and access to knowledge and information. The specific barriers included poor work coordination among implementers, limited resources to support the expansion of AHD screening, and knowledge gap among providers. External support from Ministry of Health implementing partners and the availability of committed focal leaders coordinating HIV programs emerged as major enablers of AHD screening package. CONCLUSION: The study has identified major contextual barriers to AHD screening including knowledge gap, poor communication systems and inadequate supporting resources. Improving uptake of AHD screening services would therefore require overcoming the existing barriers by adopting a comprehensive approach in developing barrier-tailored strategies.

Retrospective Cohort Study Comparing Antiretroviral Treatment Outcomes Among Adolescents in Teen Clubs and Standard Care Clinics: Blantyre, Malawi.

INTRODUCTION: This study investigated if the Teen Club model improves virological suppression and reduces virological failure. Viral load monitoring is a golden ART programme performance indicator. HIV treatment outcomes are poor among adolescents compared to adults. Different service delivery models are being implemented to address this; among them is the Teen Club model. Currently, teen clubs improve treatment adherence (short-term impact), but there is a knowledge gap regarding the long-term impact. The study compared the rate of virological suppression and failure among adolescents in Teen Clubs and those on the standard of care (SoC) model. METHODS: This was a retrospective cohort study. A total of 110 adolescents in teen clubs and 123 adolescents in SOC from six health facilities were selected using stratified simple random sampling. The participants were followed for 24 months. STATA version 16.0 was used for data analysis. Univariate analyses were performed for both demographic and clinical variables. A Chi-squared test was used to assess the differences between proportions. Crude and adjusted relative risks were calculated using a binomial regression model. RESULTS: At 24 months, 56% of adolescents in the SoC arm had viral load suppression compared to 90% in the Teen Club arm. Of those who achieved viral load suppression at 24 months, about 22.7% (SoC) and 76.4% (Teen Club) achieved undetectable viral load suppression rates. Adolescents in the Teen Club arm had a lower viral load than those in the SoC arm (adjusted RR 0.23, 95% CI: 0.11-0.61; p = 0.002 adjusted for age and gender). Teen Club and SoC adolescents had virological failure rates of 3.1% and 10.9%, respectively. The adjusted RR was 0.16, 95% CI: 0.03-0.78; p = 0.023; those in Teen Clubs were less likely to have virological failure relative to those in SoC after adjusting for age, sex, and place of residence. CONCLUSION: The study found that Teen Club models are more effective at achieving virological suppression among HIV positive adolescents.

Barriers and facilitators to implementing Advanced HIV Disease screening at secondary referral hospital -Malawi: Asequential exploratory mixed method-study.

Background Malawi continues to register increased HIV/AIDs mortality despite increased expansion of ART services. One of the strategies for reducing AIDS related deaths outlined in the Malawi National HIV Strategic Plan (NSP) is scaling up screening for AHD in all antiretroviral therapy (ART) screening sites. This study investigated factors influencing the implementation of the advanced HIV disease (AHD) screening package at Rumphi District Hospital, Malawi. Methods We conducted a mixed method, sequential exploratory study from March, 2022 to July, 2022. The study was guided by a consolidated framework of implementation research (CFIR). Interviews were administered to key healthcare providers, purposively selected from various hospital departments. Transcripts were organized and coded using NVivo 12 software with thematically predefined CFIR constructs. Newly HIV-positive client records extracted from ART cards (July -Dec, 2021) were analyzed using STATA 14 which generated table of proportions, means and standard deviations. Results Out of 101 data records of the new ART clients reviewed, 60% {(n = 61) had no documented results for CD4 Cell count as a baseline screening test for AHD. Four major themes emerged as barriers: complexity of the intervention, poor work coordination, limited resources to support the expansion of point of care services for AHD, knowledge and information gap among providers. Technical support from MoH implementing partners and the availability of committed focal leaders coordinating HIV programs emerged as major facilitators of AHD screening package. Conclusion The study has identified major contextual barriers to AHD screening affecting work coordination and client linkage to care. Improving coverage of AHD screening services would therefore require overcoming the existing barriers such communication and information gaps.

The Association of Low Blood Glucose and Low Serum Cortisol Levels in Severely Ill Children Admitted to Tertiary Referral Hospitals in Malawi: A Case-Control Study.

Low blood glucose concentrations < 5 mmol/L in severely ill children presenting to hospitals in low-income countries are associated with mortality. Adrenal insufficiency with low cortisol levels may contribute to low blood glucose concentrations. Understanding the association between low cortisol and low blood glucose may assist in improving guidelines for management of severely ill children. The study aimed to determine the association between low serum cortisol and low blood glucose in severely ill children. A matched case-control study of children aged 1 month to 15 years was conducted at two tertiary hospitals in Malawi. Cases were children with blood glucose < 5 mmol/L. Two age-matched controls with blood glucose of ≥ 5-15 mmol/L were enrolled per case. Low cortisol was defined as serum cortisol of < 25 µg/dL (690 nmol/L) and adrenal insufficiency as serum cortisol of < 10 µg/dL (276 nmol/L). A total of 54 cases and 108 controls were enrolled with, median age of 2.8 years (interquartile range [IQR]: 1.7-4.4). The median cortisol level was 58.7 µg/dL (IQR: 42.3-61.8) in cases and 40.9 µg/dL (IQR: 33.7-51.2) in controls (P = 0.911). The proportion of low cortisol was 4/54 (7.4%) in cases and 9/108 (8.3%) in controls. Logistic regression shows no association between low cortisol and low blood glucose (adjusted odds ratio: 0.33; 95% confidence interval, 0.04-3.02). Results suggest that there is no association between low cortisol and low blood glucose among severely ill children presenting to hospitals in Malawi. The reason for low blood glucose needs further investigation.

Effect on mortality of increasing the cutoff blood glucose concentration for initiating hypoglycaemia treatment in severely sick children aged 1 month to 5 years in Malawi (SugarFACT): a pragmatic, randomised controlled trial.

BACKGROUND: Low blood glucose concentrations are common in sick children who present to hospital in low-resource settings and are associated with increased mortality. The cutoff blood glucose concentration for the diagnosis and treatment of hypoglycaemia currently recommended by WHO (2·5 mmol/L) is not evidence-based. We aimed to assess whether increasing the cutoff blood glucose concentration for hypoglycaemia treatment in severely ill children at presentation to hospital improves mortality outcomes. METHODS: We did a pragmatic, randomised controlled trial at two referral hospitals in Malawi. Severely ill children aged 1 month to 5 years presenting to the emergency department with a capillary blood glucose concentration of between 2·5 mmol/L (3·0 mmol/L in severely malnourished children) and 5·0 mmol/L were randomly assigned (1:1) by a computer-generated randomisation sequence, stratified by study site and severe malnutrition, to receive either an immediate intravenous bolus of 10% dextrose at 5 mL/kg followed by a 24-h maintenance infusion of 10% dextrose at 100 mL/kg for the first 10 kg of bodyweight, 50 mL/kg for the next 10 kg, and 20 mL/kg for each subsequent kg of bodyweight (intervention group) or observation for a minimum of 60 min and standard care (control group). Participants and study personnel were not masked to treatment allocation. The primary outcome was all-cause in-hospital mortality, assessed on an intention-to-treat basis. Safety was also assessed in the intention-to-treat population. The study is registered with ClinicalTrials.gov, NCT02989675. FINDINGS: Between Dec 5, 2016, and Jan 22, 2019, 10 947 children were screened, of whom 332 were randomly assigned, and 322 were included in the final analysis (n=162 in the control group and n=160 in the intervention group). The study was terminated after an interim analysis at 24% enrolment indicated futility. The median age of participants was 2·3 years (IQR 1·4-3·2), 65 (45%) were female, and the baseline characteristics of participants were similar between the two groups. The number of in-hospital deaths from any cause was 26 (16%) in the control group and 24 (15%) in the intervention group, with an absolute mortality difference of 1·0% (95% CI -6·9 to 9·0). Serious adverse events, including hypoglycaemia, hyperglycaemia, convulsions, reduced consciousness, and death, were reported in 47 (29%) children in the control group and 39 (24%) children in the intervention group. INTERPRETATION: Increasing the cutoff blood glucose concentration for hypoglycaemia treatment in severely sick children in Malawi from 2·5 mmol/L to 5·0 mmol/L did not reduce all-cause in-hospital mortality. Our findings do not support changing the cutoff for dextrose administration, and further research on the optimal management of severely ill children who present to the emergency department with low blood glucose concentrations is warranted.

Feeding practices and association of fasting and low or hypo glycaemia in severe paediatric illnesses in Malawi - a mixed method study.

BACKGROUND: The presence of low or hypo glycaemia in children upon admission to hospital in low income countries is a marker for poor outcome. Fasting during illness may contribute to low blood glucose and caretakers' feeding practices during childhood illnesses may thus play a role in the development of low or hypo glycaemia. This study aims to describe the caretaker's feeding practices and association of fasting with low or hypo glycaemia in sick children in Malawi. METHODS: A mixed method approach was used combining quantitative cross-sectional data for children aged 0-17 years admitted to Queen Elizabeth Central Hospital (QECH), a tertiary hospital in Malawi, with qualitative focus group discussions conducted with caretakers of young children who were previously referred to QECH from the five health centres around QECH. Logistic regression was used to analyse the quantitative data and thematic content analysis was conducted for qualitative data analysis. RESULTS: Data for 5131 children who were admitted through the hospital's Paediatric Accident and Emergency Department (A&E) were analysed whereof 2.1% presented with hypoglycaemia (< 2.5 mmol/l) and 6.6% with low glycaemia (≥2.5mmoll/l - < 5 mmol/l). Fasting for more than eight hours was associated with low glycaemia as well as hypoglycaemia with Adjusted Odds Ratios (AOR) of 2.9 (95% Confidence Interval (CI) of 2.3-3.7) and 4.6, (95% CI 3.0-7.0), respectively. Caretakers demonstrated awareness of the importance of feeding during childhood illness and reported intensified feeding attention to sick children but face feeding challenges when illness becomes severe causing them to seek care at a health facility. CONCLUSION: Results suggests that caretakers understand the importance of feeding during illness and make efforts to intensify feeding a sick child but challenges occur when illness is severe leading to fasting. Fasting among children admitted to hospitals may serve as a marker of severe illness and determine those at risk of low and hypoglycaemia.

Risk Factors for Mortality in Severely Ill Children Admitted to a Tertiary Referral Hospital in Malawi.

In low-resource settings, many children are severely ill at arrival to hospital. The risk factors for mortality among such ill children are not well-known. Understanding which of these patients are at the highest risk could assist in the allocation of limited resources to where they are most needed. A cohort study of severely ill children treated in the resuscitation room of the pediatric emergency department at Queen Elizabeth Central Hospital in Malawi was conducted over a 6-month period in 2017. Data on signs and symptoms, vital signs, blood glucose levels, and nutritional status were collected and linked with in-hospital mortality data. The factors associated with in-hospital mortality were analyzed using multivariable logistic regression. Data for 1,359 patients were analyzed and 118 (8.7%) patients died. The following factors were associated with mortality: presence of any severely deranged vital sign, unadjusted odds ratio (UOR) 2.6 (95% CI 1.7-4.0) and adjusted odds ratio (AOR) 3.2 (95% CI 2.0-5.0); severe dehydration, UOR 2.6 (1.4-5.1) and AOR 2.8 (1.3-6.0); hypoglycemia glycemia (< 5 mmol/L), UOR 3.6 (2.2-5.8) and AOR 2.7 (1.6-4.7); and severe acute malnutrition, UOR 5.8 (3.5-9.6) and AOR 5.7 (3.3-10.0). This study suggests that among severely sick children, increased attention should be given to those with hypo/low glycemia, deranged vital signs, malnutrition, and severe dehydration to avert mortality among these high-risk patients.
