Effectiveness of intensive adherence counselling in achieving an undetectable viral load among people on antiretroviral therapy with low-level viraemia in Uganda.

INTRODUCTION: Uganda was using a threshold of 1000 copies/mL to determine viral non-suppression for antiretroviral therapy monitoring among people living with HIV, prior to this study. It was not clear whether people living with HIV with low-level viraemia (LLV, ≥50 to <1000 copies/mL) would benefit from intensive adherence counselling (IAC). The purpose of this study was to determine the effectiveness of IAC among people living with HIV, receiving antiretroviral therapy, and with LLV in Uganda, to guide key policy decisions in HIV care, including the review of the viral load (VL) testing algorithm. METHODS: This cluster-randomized clinical trial comprised adults from eight HIV clinics who were living with HIV, receiving ART, and had recent VL results indicating LLV (tested from July 2022 to October 2022). Participants in the intervention arm clinics received three once-monthly sessions of IAC, and those in the comparison non-intervention arm clinics received the standard of care. At the end of the study, all participants were re-tested for VL to determine the proportions of those who then had an undetectable VL (<50 copies/mL). We assessed the statistical association between cross-tabulated variables using Fisher's exact test and then modified Poisson regression. RESULTS: A total of 136 participants were enrolled into the study at eight HIV clinics. All 68 participants in the intervention arm completed all IAC sessions. Only one participant in the non-intervention arm was lost to follow-up. The average follow-up time was 3.7 months (standard deviation [SD] 0.2) and 3.5 months (SD 0.1) in the intervention and non-intervention arms, respectively. In total, 59 (43.7%) of 135 people living with HIV achieved an undetectable VL during the study follow-up period. The effect of IAC on attaining an undetectable VL among people with LLV was nearly twice as high in the intervention arm (57.4%) than in the non-intervention arm (29.9%): adjusted risk ratio 1.9 (95% confidence interval 1.0-3.5), p = 0.037. CONCLUSION: IAC doubled the likelihood of an undetectable VL among people living with HIV with LLV. Therefore, IAC has been instituted as an intervention to manage people living with HIV with LLV in Uganda, and this should also be adopted in other Sub-Saharan African countries with similar settings.

Hopes, joys and fears: Meaning and perceptions of viral load testing and low-level viraemia among people on antiretroviral therapy in Uganda: A qualitative study.

Uganda applies the World Health Organization threshold of 1,000 copies/ml to determine HIV viral non-suppression. While there is an emerging concern of low-level viraemia (≥50 to <1,000 copies/ml), there is limited understanding of how people on antiretroviral therapy perceive viral load testing and low-level viremia in resource-limited settings. This qualitative study used the health belief model to explore the meaning that people living with HIV attach to viral load testing and low-level viraemia in Uganda. We used stratified purposive sampling to select people on antiretroviral therapy from eight high volume health facilities from the Central, Eastern, Northern and Western regions of Uganda. We used an interview guide, based on the health belief model, to conduct 32 in-depth interviews, which were audio-recorded and transcribed verbatim. Thematic analysis technique was used to analyze the data with the help of ATLAS.ti 6. The descriptions of viral load testing used by the participants nearly matched the medical meaning, and many people living with HIV understood what viral load testing was. Perceived benefits for viral load testing were the ability to show; the amount of HIV in the body, how the people living with HIV take their drugs, whether the drugs are working, and also guide the next treatments steps for the patients. Participants reported HIV stigma, lack of transport, lack of awareness for viral load testing, delayed and missing viral load results and few health workers as the main barriers to viral load testing. On the contrary, most participants did not know what low-level viraemia meant, while several perceived it as having a reduced viral load that is suppressed. Many people living with HIV are unaware about low-level viraemia, and hence do not understand its associated risks. Likewise, some people living with HIV are still not aware about viral load testing. Lack of transport, HIV stigma and delayed viral load results are major barriers to viral load testing. Hence, there is an imminent need to institute more strategies to create awareness about both low-level viraemia and viral load testing, manage HIV related stigma, and improve turnaround time for viral load results.

Factors Associated with Retention in HIV Care Among HIV-Positive Adolescents in Public Antiretroviral Therapy Clinics in Ibanda District, Rural South Western Uganda.

Background: Retention in antiretroviral therapy (ART) care is a key indicator of Human Immunodeficiency Virus (HIV) treatment success as it improves adherence, critical for better treatment outcomes and prevention of drug resistance. HIV treatment among adolescents living with HIV (ALHIV) is characterized by loss to follow-up, poor ART adherence, and eventual death. This study assessed retention in ART care and the associated factors among ALHIV in Ibanda district, rural South Western Uganda. Methods: This was a retrospective cohort study using clinical data from ALHIV enrolled from 2019 to 2020 in eight health facilities in Ibanda district. Data from the Electronic Medical Record (EMR) system was extracted to assess the associated factors and participants' status two years after enrollment. Data were analyzed using EPIdata version 3.1 in which Univariate and multivariate cox proportional hazard regression analyses were determined. A hazard ratio (HR) at a 95% confidence interval was obtained, and a P-value <0.05 was considered statistically significant. Results: Eighty-four ALHIV comprising 86.9% (N = 73) females were enrolled. The majority 63.1% (N = 53) resided in semi/peri-urban, and 44.0% (N = 37) stayed less than 5 km from the facility. Only 35.7% (N = 30) were active on ART, while 17 (20.2%) and 36 (42.9%) were lost to follow-up and transfer-outs, respectively. Factors associated with low retention were: ALHIV that moved 5-10Km (HR = 5.371; 95% CI: 1.227-23.5050, p = 0.026), used differential service delivery model was Facility-Based Group (FBG) (HR = 12.419; 95% CI: 4.034-38.236, p < 0.001) and those enrolled on the Young Adolescent Program Support (YAPs) (HR = 4.868; 95CI:1.851-12.803; p = 0.001). Retention reduced with increasing ART duration, ALHIV on (TDF/3TC/EFV) (p < 0.001), lived more than 10Km (p = 0.043) and did not benefit from any intervention (p < 0.001). Conclusion: Results showed low retention in care and the urgent need to strengthen individual case management strategies for ALHIV, thus interventions focusing on peer support are desired.

The association between low-level viraemia and subsequent viral non-suppression among people living with HIV/AIDS on antiretroviral therapy in Uganda.

BACKGROUND: Uganda's efforts to end the HIV epidemic by 2030 are threatened by the increasing number of PLHIV with low-level viraemia (LLV). We conducted a study to determine the prevalence of LLV and the association between LLV and subsequent viral non-suppression from 2016 to 2020 among PLHIV on ART in Uganda. METHOD: This was a retrospective cohort study, using the national viral load (VL) program data from 2016 to 2020. LLV was defined as a VL result of at least 50 copies/ml, but less than 1,000 copies/ml. Multivariable logistic regression was used to determine the factors associated with LLV, and cox proportional hazards regression model was used to determine the association between LLV and viral non-suppression. RESULTS: A cohort of 17,783 PLHIV, of which 1,466 PLHIV (8.2%) had LLV and 16,317 (91.8%) had a non-detectable VL was retrospectively followed from 2016 to 2020. There were increasing numbers of PLHIV with LLV from 2.0% in 2016 to 8.6% in 2020; and LLV was associated with male sex, second line ART regimen and being of lower age. 32.5% of the PLHIV with LLV (476 out of 1,466 PLHIV) became non-suppressed, as compared to 7.7% of the PLHIV (1,254 out of 16,317 PLHIV) with a non-detectable viral load who became non-suppressed during the follow-up period. PLHIV with LLV had 4.1 times the hazard rate of developing viral non-suppression, as compared to PLHIV with a non-detectable VL (adjusted hazard ratio was 4.1, 95% CI: 3.7 to 4.7, p < 0.001). CONCLUSION: Our study indicated that PLHIV with LLV increased from 2.0% in 2016 to 8.6% in 2020, and PLHIV with LLV had 4.1 times the hazard rate of developing viral non-suppression, as compared to PLHIV with a non-detectable VL. Hence the need to review the VL testing algorithm and also manage LLV in Uganda.

Low-level viraemia: An emerging concern among people living with HIV in Uganda and across sub-Saharan Africa.

Attaining viral load (VL) suppression for over 95% of the people living with HIV on antiretroviral therapy is a fundamental step in enabling Uganda and other sub-Saharan African countries to achieve global Sustainable Development Goal targets to end the HIV/AIDS epidemic by 2030. In line with the 2013 World Health Organization recommendations, several sub-Saharan African countries, including Uganda, use a threshold of 1000 HIV viral RNA copies/mL to determine HIV viral non-suppression. The United States Centers for Disease Control and Prevention and the International Association of Providers of AIDS Care deem this threshold very high, and hence recommend using 200 copies/mL to determine viral non-suppression. Using 1000 copies/mL as a threshold ignores people living with HIV who have low-level viraemia (LLV; HIV VL of at least 50 copies/mL but less than 1000 copies/mL). Despite the 2021 World Health Organization recommendations of using intensive adherence counselling for people living with HIV with LLV, several sub-Saharan African countries have no interventions to address LLV. However, recent studies have associated LLV with increased risks of HIV drug resistance, virologic failure and transmission. The purpose of this narrative review is to provide insights on the emerging concern of LLV among people living with HIV receiving antiretroviral therapy in sub-Saharan Africa. The review also provides guidance for Uganda and other sub-Saharan African countries to implement immediate appropriate interventions like intensive adherence counselling, reducing VL thresholds for non-suppression and conducting more research to manage LLV which threatens progress towards ending HIV by 2030.

Early observations from the HIV self-testing program among key populations and sexual partners of pregnant mothers in Kampala, Uganda: A cross sectional study.

BACKGROUND: HIV self-testing (HIVST) was adopted for key populations (KPs) and sexual partners of pregnant and lactating women (mothers) in Uganda in October 2018. We report early observations during HIVST implementation in Kampala, Uganda. METHODS: HIVST was rolled out to reach those with unknown HIV status at 38 public health facilities, using peer-to-peer community-based distribution for female sex workers (FSW) and men who have sex with men (MSM) and secondary distribution for mothers, who gave HIVST kits to their partners. Self-testers were asked to report results within 2 days; those who did not report received a follow-up phone call from a trained health worker. Those with HIV-positive results were offered confirmatory testing at the facility using the standard HIV-testing algorithm. Data on kits distributed, testing yield, and linkage to care were analysed. RESULTS: We distributed 9,378 HIVST kits. Mothers received 5,212 (56%) for their sexual partners while KPs received 4,166 (44%) (MSM, 2192 [53%]; FSW1, 974, [47%]). Of all kits distributed, 252 (3%) individuals had HIV-positive results; 126 (6.5%) FSW, 52 (2.3%) MSM and 74 (1.4%) partners of mothers. Out of 252 individuals who had HIV-positive results, 170 (67%) were confirmed HIV-positive; 36 (2%) were partners of mothers, 99 (58%) were FSW, and 35 (21%) were MSM. Linkage to treatment (126) was 74%. CONCLUSIONS: HIVST efficiently reached, tested, identified and modestly linked to care HIV positive FSW, MSM, and partners of mothers. However, further barriers to confirmatory testing and linkage to care for HIV-positive self-testers remain unexplored.

The Effects of Workplace-Based HIV Self-testing on Uptake of Testing and Linkage to HIV Care or Prevention by Men in Uganda (WISe-Men): Protocol for a Cluster Randomized Trial.

BACKGROUND: HIV testing uptake remains low among men in sub-Saharan Africa. HIV self-testing (HIVST) at the workplace is a novel approach to increase the availability of, and access to, testing among men. However, both access and linkage to posttest services remain a challenge. OBJECTIVE: The aim of this protocol is to describe a cluster randomized trial (CRT)-Workplace-Based HIV Self-testing Among Men (WISe-Men)-to evaluate the effect of HIVST in workplace settings on the uptake of HIV testing services (HTS) and linkage to treatment and prevention services among men employed in private security services in Uganda. METHODS: This is a two-arm CRT involving men employed in private security services in two Ugandan districts. The participants in the intervention clusters will undergo workplace-based HIVST using OraQuick test kits. Those in the control clusters will receive routine HTS at their work premises. In addition to HTS, participants in both the intervention and control arms will undergo other tests and assessments, which include blood pressure assessment, blood glucose and BMI measurement, and rapid diagnostic testing for syphilis. The primary outcome is the uptake of HIV testing. The secondary outcomes include HIV status reporting, linkage into HIV care and confirmatory testing following HIVST, initiation of antiretroviral therapy following a confirmatory HIV test, the uptake of voluntary medical male circumcision, consistent condom use, and the uptake of pre-exposure prophylaxis by the most at-risk populations. RESULTS: Participant enrollment commenced in February 2020, and the trial is still recruiting study participants. Follow-up for currently enrolled participants is ongoing. Data collection and analysis is expected to be completed in December 2021. CONCLUSIONS: The WISe-Men trial will provide information regarding whether self-testing at worksites increases the uptake of HIV testing as well as the linkage to care and prevention services at male-dominated workplaces in Uganda. Additionally, the findings will help us propose strategies for improving men's engagement in HTS and ways to improve linkage to further care following a reactive or nonreactive HIVST result.

Venues and methods to improve professional men's access to HIV self-testing and linkage to HIV prevention or treatment: a qualitative study.

BACKGROUND: HIV testing among men in sub-Saharan Africa is sub-optimal. Despite several strategies to improve access to underserved populations, evidence regarding engaging men in professional and formal occupations in HIV testing is limited. This study explored employed professional men's preferences for uptake of HIV self-testing, and linkage to HIV care, or prevention services. METHODS: This was an explorative-descriptive qualitative study where a sample of 33 men from six Ugandan urban centres. Participants were purposively selected guided by the International Standard Classification of Occupations to participate in in-depth interviews. The data were collected using an interview guide and the sample size was determined by data saturation. Eligibility criteria included fulltime formal employment for over a year at that organization. The data were analyzed manually using thematic content analysis. RESULTS: Three categories emerged: uptake of HIV self-tests, process of HIV self-testing and linkage to post-test services. The different modes of distribution of HIV self-test kits included secondary distribution, self-tests at typically male dominated spaces, delivery to workplaces and technology-based delivery. The process of HIV self-testing may be optimized by providing collection bins, and mHealth or mobile phone applications. Linkage to further care or prevention services may be enhanced using medical insurance providers, giving incentives and tele counselling. CONCLUSION: We recommend utilization of several channels for the uptake of HIV self-tests. These include distribution of test kits both to offices and men's leisure and recreation 'hot spots', Additionally, female partners, peers and established men's group including social media groups can play a role in improving the uptake of HIV self-testing. Mobile phones and digital technology can be applied in innovative ways for the return of test results and to strengthen linkage to care or prevention services. Partnership with medical insurers may be critical in engaging men in professional employment in HIV services.

Short report: knowledge and perceptions of health workers that strengthen adherence for paediatric and adolescent clients on the intensive adherence counselling program in Kampala, Uganda: a qualitative study.

BACKGROUND: Health care workers (HWs) support HIV positive children and adolescents with detectable HIV viral loads on the intensive adherence counselling (IAC) program to achieve viral suppression through individual adherence counselling. Low re-suppression rates of 23% showed low program effectiveness in fifteen public health facilities. OBJECTIVES: We set out to determine the knowledge and perceptions of HWs that support this program to improve its effectiveness. METHODS: We conducted a qualitative study where five HWs that oversee clinical care for children on ART were interviewed about the program. Data on their knowledge of the program, and perceptions on why it was not effective was collected. Thematic analysis using the inductive approach was used. Transcripts were read, coded and emergent themes determined. RESULTS: Five HWs participated and all were knowledgeable about the program. Two themes emerged as barriers to IAC program effectiveness, patient factors and health system factors. Patient factors were failure to attend appointments, failure to change adherence practices, and lack of consent. Health system factors were work overload, delay in getting results and drug stock outs. CONCLUSIONS: HWs are knowledgeable about the IAC program and client specific barriers should be addressed to improve viral suppression for children.

Experiential Learning and Mentorship in Global Health Leadership Programs: Capturing Lessons from Across the Globe.

Objectives: The changing global landscape of disease and public health crises, such as the current COVID-19 pandemic, call for a new generation of global health leaders. As global health leadership programs evolve, many have incorporated experiential learning and mentoring (ELM) components into their structure. However, there has been incomplete consideration on how ELM activities are deployed, what challenges they face and how programs adapt to meet those challenges. This paper builds on the co-authors' experiences as trainees, trainers, organizers and evaluators of six global health leadership programs to reflect on lessons learned regarding ELM. We also consider ethics, technology, gender, age and framing that influence how ELM activities are developed and implemented. Findings: Despite the diverse origins and funding of these programs, all six are focused on training participants from low- and middle-income countries drawing on a diversity of professions. Each program uses mixed didactic approaches, practice-based placements, competency and skills-driven curricula, and mentorship via various modalities. Main metrics for success include development of trainee networks, acquisition of skills and formation of relationships; programs that included research training had specific research metrics as well. Common challenges the programs face include ensuring clarity of expectations of all participants and mentors; maintaining connection among trainees; meeting the needs of trainee cohorts with different skill sets and starting points; and ensuring trainee cohorts capture age, gender and other forms of diversity. Conclusions: ELM activities for global health leadership are proving even more critical now as the importance of effective individual leaders in responding to crises becomes evident. Future efforts for ELM in global health leadership should emphasize local adaptation and sustainability. Practice-based learning and established mentoring relationships provide the building blocks for competent leaders to navigate complex dynamics with the flexibility and conscientiousness needed to improve the health of global populations. Key Takeaways: Experiential learning and mentorship activities within global health leadership programs provide the hands-on practice and support that the next generation of global health leaders need to address the health challenges of our times.Six global health leadership programs with experiential learning and mentorship components are showcased to highlight differences and similarities in their approaches and capture a broad picture of achievements that can help inform future programs.Emphasis on inter-professional training, mixed-learning approaches and mentorship modalities were common across programs. Both individual capacity building and development of trainees' professional networks were seen as critical, reflecting the value of inter-personal connections for long-term leadership success.During program design, future programs should recognize the "frame" within which the program will be incorporated and intentionally address diversity-in all its forms-during recruitment as well as consider North-South ethics, leadership roles, hierarchies and transition plans.

Conducting an ongoing HIV clinical trial during the COVID-19 pandemic in Uganda: a qualitative study of research team and participants' experiences and lessons learnt.

OBJECTIVE: To explore the experiences and lessons learnt by the study team and participants of the Workplace-based HIV self-testing among Men trial during the COVID-19 pandemic in Uganda. DESIGN: An explorative qualitative study comprising two virtual focus group discussions (FGDs) with 12 trial team members and 32 in-depth participant interviews (N=44). Data were collected via telephone calls for in-depth interviews or Zoom for FGDs and manually analysed by inductive content analysis. SETTING: Fourteen private security companies in two Uganda districts. PARTICIPANTS: Members of the clinical trial study team, and men working in private security companies who undertook workplace-based HIV testing. RESULTS: The key themes for participants experiences were: 'challenges in accessing HIV treatment and care, and prevention services', 'misinformation' and 'difficulty participating in research activities'. The effects on HIV treatment and prevention resulted from; repercussions of the COVID-19 restrictions, participants fear of coinfection and negative experiences at health facilities. The difficulty in participating in research activities arose from: fear of infection with COVID-19 for the participants who tested HIV negative, transport difficulties, limited post-test psychosocial support and lack of support to initiate pre-exposure prophylaxis. The key study team reflections focused on the management of the clinical trial, effects of the local regulations and government policies and the need to adhere to ethical principles of research. CONCLUSIONS: Findings highlight the need to organise different forms of HIV support for persons living with HIV during a pandemic. Additionally, the national research regulators and ethics committees or review boards are strongly urged to develop policies and guidelines for the continuity of research and clinical trials in the event of future shocks. Furthermore, this study calls on the appropriate government agencies to ensure public and researchers' preparedness through continuing education and support.

Employers' and Employees' Perspectives of HIV Self-Testing at Male-Dominated Work Sites and Linkage to Posttest Services in Uganda.

This study explored men's views of workplace-based HIV self-testing and the barriers and facilitators of linkage to posttest services. Six focus group discussions and individual in-depth interviews were held with employers and employees in private security companies in Uganda (N = 70). Using content analysis, five categories emerged. The first category was the mitigation of potential harm, including reduction of stigma and discrimination, and the need for posttest support. The second category was a perceived need for on-site services where the men proposed on-site prevention services and HIV treatment and care. In the third category, which was strengthening linkage mechanisms, participants proposed expanded clinic hours, improved health facility efficiency, and provision of referral documentation. The fourth and fifth categories were organizational support and social support, respectively. There is need for employers and employees to work together for the success of workplace-based HIV initiatives.

Reduction in Baseline CD4 Count Testing Following Human Immunodeficiency Virus "Treat All" Adoption in Uganda.

Baseline CD4 testing rates declined from 73% to 21% between 2013 and 2018 with adoption of "Treat All" in Uganda. Advanced human immunodeficiency virus (HIV) disease (CD4 count < 200 cells/µL) remained common (24% of those tested in 2018, 83% of whom had World Health Organization stage I/II disease). Despite frequent presentation with advanced HIV disease, CD4 testing has declined dramatically.

Challenges faced by caregivers of virally non-suppressed children on the intensive adherence counselling program in Uganda: a qualitative study.

BACKGROUND: Of the estimated 130,000 children living with HIV in Uganda, 47% are receiving ART. Only 39.3% have suppressed HIV-1 viral load to levels below 50 copies per ml. Caregivers are key drivers of adherence to achieve viral suppression in children. We investigated the challenges and potential support required by caregivers of ART-treated children. METHODS: A qualitative study was conducted within the Infectious Diseases Institute paediatric ART program in Kampala and Hoima districts. Caregivers of children with viral loads above 1000 copies were purposively sampled and engaged in five focus group discussions (FGD). The FGD guide highlighted questions on challenges that caregivers face and the kind of support they required to improve children's ART adherence. Thematic analysis using the inductive approach was used. All the transcripts were read, coded and emergent themes determined. RESULTS: Overall, 37 caregivers participated in five FGD, of whom 29 (78%) were female, 28 (76%) were HIV-infected and 25 (68%) were biological parents of the children. The elicited challenges were either in failure to attend the counselling sessions or in supporting adherence to medication. Individual and health system challenges such as competing priorities, logistics, poor quality of counselling and lack of reminders prevented attendance at counselling sessions. Five themes emerged as challenges to supporting adherence: i) environmental (school activities, working away from home), ii) personal (non-disclosure, stigma), iii) psychological (guilt), iv) financial (lack of food and transport) and v) child-related (fatigue and peer influence). Three major themes emerged for the support that caregivers needed namely: a) health system reforms (clinic appointments outside school hours, minimize ART drug stock outs and improve quality of counselling), b) psychosocial support (support with disclosure of HIV status to children and their families, more frequent peer support groups and parenting classes) and c) economic empowerment (training in vocational skills, school fees support and opportunities to initiate income generating activities). DISCUSSION AND CONCLUSION: To achieve viral suppression, ART programs require targeted efforts to provide specific health facility requirements, psychological and economic needs of ART-treated children and their caregivers. Integration of HIV treatment with programs for orphans and vulnerable children may improve viral suppression rates.

Low HIV viral suppression rates following the intensive adherence counseling (IAC) program for children and adolescents with viral failure in public health facilities in Uganda.

BACKGROUND: The UNAIDS 90-90-90 strategy clearly stipulates that 90% of all people on antiretroviral therapy (ART) should have a suppressed viral load. Intensified adherence counselling (IAC) was recently recommended by WHO to improve viral suppression among ART-treated paediatric and adolescent clients with virological failure. This paper describes the implementation and outcomes of IAC in the first year of implementation in a public ART program, to inform strategic interventions to reach the "third 90" among children. METHODS: A retrospective chart review was conducted for all children aged 9 months to 19 years with HIV viral loads (VL) ≥ 1000 copies/ml at 15 public health facilities from June 2015-December 2016. Data on initial VL test results, IAC sessions, repeat VL test results, and ART regimen switch were abstracted and analysed for completion of IAC and viral suppression after IAC. RESULTS: A total of 449 children had a detectable viral load above 1000 copies/ml, after an average of 3.5 years (SD 5.8) years of ART. 192 (43%) were 10-20 years of age, and 320 (71%) were receiving Nevirapine-based ART regimen. Out of 345 (77%) who completed the recommended three IAC sessions, 62 (23%) achieved viral suppression following IAC. The mean time from 1st to 3rd IAC session was 113 (SD 153) days and 172 (50%) of the children had completed the three sessions within 200 days. CONCLUSION: Suppression rates were low among ART-treated children with virological failure that completed the recommended three IAC sessions. As we move towards having 90% of ART-treated children and adolescents achieve and maintain viral suppression, there is need to re-evaluate the implementation of IAC among children and adolescents to consider both psychosocial and biological factors such as resistance testing for those with multiple detectable viral loads.

Examining the relationship between childhood health conditions and health service utilisation at school entry and subsequent academic performance in a large cohort of Australian children.

AIM: Chronic health conditions are associated with poor academic outcomes. This study examines the relationship between health conditions, specialist health service utilisation and academic performance in Australian children. METHODS: This was a quasi-longitudinal study where School Entrant Health Questionnaire (a survey tool with parent report on children's health) data for 24 678 children entering school in 2008 was matched with the 2011 National Assessment Program - Literacy and Numeracy (NAPLAN). Linear and logistic regressions were used to examine associations between health conditions, use of a specialist health service and reading and numeracy scores. RESULTS: The study comprised 24 678 children. Children with allergies, very low birth weight, developmental delay, diabetes, spina bifida, cystic fibrosis, birth abnormality, speech problems, intellectual disability and attention-deficit/hyperactivity disorder had lower numeracy scores than those without any of these conditions (P < 0.05). The same children had higher odds (1.2-5.8) of being at or below the national minimum standard for numeracy. Children with developmental delay, epilepsy, dental problems, speech, intellectual disabilities and low birth weight had lower reading scores than those without these conditions (P < 0.05) and had higher odds of being at (odds ratio: 1.3) or below (odds ratio: 3.7) the national minimum standard for reading. Children with health conditions who had ever accessed specialist health services did not differ in their academic performance from those that had not used specialist health services. CONCLUSIONS: Some health conditions put children at risk of poorer academic performance, and interventions to prevent this such as appropriate support services in schools should be considered.

Implementation and effect of intensified case finding on diagnosis of tuberculosis in a large urban HIV clinic in Uganda: a retrospective cohort study.

BACKGROUND: Increased detection of tuberculosis (TB) using intensified or active case finding (ICF) is one of the cornerstones of the Stop TB Strategy, and contrasts with passive case finding (PCF) which relies on self-reported symptoms. There is no clear guidance on implementation strategies. We implemented ICF in addition to ongoing PCF in our large urban HIV clinic in July 2010 using a twice-daily announcement screen method by a trained peer educator, asking waiting patients to self-refer to a trained peer supporter for screening of TB symptoms. We sought to determine the associated effect on TB case detection. METHODS: Suspects were investigated by sputum smear, chest X-ray and ultrasound, if indicated. Routinely collected clinical and laboratory data were merged with the ICF register and TB clinic data for patients attending the clinic in 2010. We compared the yield of TB cases (defined as the prevalence of newly diagnosed TB cases in the screened population), the type of TB diagnosed and the total cost per TB case identified (in United States Dollars [USD]) for the period before and after ICF implementation. RESULTS: Of the 20,456 patients who visited the clinic in 2010, 614 were identified as TB suspects, 220 pre-ICF and 394 post-ICF (229 via PCF and 165 via ICF). The proportion diagnosed with TB dropped from 66% to 48% (60% in suspects identified through PCF and 31% through ICF). During the post-ICF period, TB suspects identified through ICF compared to PCF identification were more likely to be female, older, on ART and to have been enrolled in HIV care for a longer duration. The yield of combined PCF and ICF screening was 1.4% pre-ICF and 1.7% post-ICF with a cost per TB case identified of 12.29 USD and 21.80 USD, respectively. CONCLUSIONS: Implementation of ICF in a large HIV clinic yielded more TB suspects and cases, but substantially increased costs and was unable to capture the majority of TB suspects who were referred for diagnosis by clinicians through PCF. The overall yield of TB cases in a mature HIV clinic was low, although targeted screening of those recently enrolled in care may increase the yield.
