RESUMO
BACKGROUND: An understanding of the prevalence patterns of skin diseases in children in Botswana is needed to guide national dermatological policy development, training, and resource allocation to improve patient care. OBJECTIVE: To describe local skin disease patterns in children aged 0-18 years presenting for dermatologic care in Botswana. METHODS: A retrospective review of records from 1st January 2011 to 31st December 2016 was conducted at the outpatient dermatology clinic of Princess Marina Hospital (PMH) in Gaborone, Botswana and outreach clinic sites. RESULTS: There were 4413 pediatric visits constituting 18.6% of all dermatology visits. There was a slight male predominance of 1.2:1. The majority of disorders were noninfectious 80.1% (3537/4413) versus infectious 14.6% (645/4413), with 5.2% (231/4413) unclassified. In the noninfectious category, two-thirds were inflammatory, followed by disorders of nails, skin appendages, and pigmentary disorders. Atopic dermatitis was the most common inflammatory disorder. Over half of infectious skin diseases were viral, followed by fungal and bacterial disorders. In the HIV-related disorders, the majority were verrucae 94% (108/115) followed by Kaposi sarcoma. The nine most common skin diagnoses accounted for close to 70% of all skin diseases seen at the clinic, and these included atopic dermatitis (almost half of all cases), followed by verruca, acne, and vitiligo. CONCLUSION: There is a high burden of skin disorders in children in Botswana. In our cohort, a small number of skin conditions made up the vast majority of pediatric diagnoses. This information can be used to guide dermatology training and resource allocation to better manage these common diseases.

We conducted a survey of doctors working in the cardiac catheterisation laboratories in Africa on their knowledge, attitude and practice with respect to radiation protection. Of seventy-two respondents contacted, 61 (84.7%) completed the questionnaire. Twenty-eight, (45.9%) were younger than 45 years. Thirty-seven, (60.6%) had less than 10 years of experience in the laboratory. Only 28 (45.9%) had undertaken radiation protection training. Fifty-eight, (95.1%) consistently used lead aprons. Forty-seven, (77%) reported consistently using thyroid shields. Ten (16.4%) consistently used radiation protection eyeglasses, whilst 36 (59%) never used them. Thermoluminescent Dosimeter badges were consistently used in 23 (37.7%). Forty-two, (68.9%) reported having ceiling mounted lead/acrylic shields. Level of radiation exposure in the most recent one year was ≤2 mSv in 14, between 2 and 20 mSv in 8 and between 20 and 30 mSv in 2, whilst 33 did not know their dose readings. The use of basic radiation protection tools as well as the knowledge and measurement of radiation exposure among interventional cardiologists working in Africa is low. The unavailability of some of the protective tools and a knowledge gap in terms of radiation protection and monitoring of self-exposure were some of the reasons for suboptimal self-protection against ionising radiation among our respondents. We suggest that initiatives be taken by all stakeholders to train this group of medical professionals in basic radiation protection to avoid unnecessary exposure to themselves, co-workers and patients.

OBJECTIVES: To describe provider characteristics, knowledge acquisition, perceived relevance, and instruction quality of the Society of Critical Care Medicine's Pediatric Fundamentals of Critical Care Support course pilot implementation in Botswana. DESIGN: Observational, single center. SETTING: Academic, upper middle-income country. SUBJECTS: Healthcare providers in Botswana. INTERVENTIONS: A cohort of healthcare providers completed the standard 2-day Pediatric Fundamentals of Critical Care Support course and qualitative survey during the course. Cognitive knowledge was assessed prior to and immediately following training using standard Pediatric Fundamentals of Critical Care Support multiple choice questionnaires. Data analysis used Fisher exact, chi-square, paired t test, and Wilcoxon rank-sum where appropriate. MAIN RESULTS: There was a significant increase in overall multiple choice questionnaires scores after training (mean 67% vs 77%; p < 0.001). Early career providers had significantly lower mean baseline scores (56% vs 71%; p < 0.01), greater knowledge acquisition (17% vs 7%; p < 0.02), but no difference in posttraining scores (73% vs 78%; p = 0.13) compared with more senior providers. Recent pediatric resuscitation or emergency training did not significantly impact baseline scores, posttraining scores, or decrease knowledge acquisition. Eighty-eight percent of providers perceived the course was highly relevant to their clinical practice, but only 71% reported the course equipment was similar to their current workplace. CONCLUSIONS: Pediatric Fundamentals of Critical Care Support training significantly increased provider knowledge to care for hospitalized seriously ill or injured children in Botswana. Knowledge accrual is most significant among early career providers and is not limited by previous pediatric resuscitation or emergency training. Further contextualization of the course to use equipment relevant to providers work environment may increase the value of training.

BACKGROUND: Botswana introduced monovalent G1P rotavirus vaccine (RV1) in July 2012, providing one of the first opportunities to assess the effectiveness of routine RV1 vaccination in a high-burden setting in Africa. We sought to determine the effectiveness of RV1 against rotavirus diarrhea hospitalization using a case-control evaluation. METHODS: Vaccine age-eligible children <5 years of age admitted with diarrhea at 4 hospitals in Botswana were enrolled from June 2013 to April 2015. Card-confirmed vaccine history was compared between case patients (children with laboratory-confirmed rotavirus diarrhea) and nonrotavirus "test-negative" diarrhea controls. Vaccine effectiveness (VE) was computed using unconditional logistic regression models adjusting for age, birth month/year, and hospital. Sequence-based genotyping was performed on antigen-positive samples. RESULTS: Among 242 case patients and 368 controls, 82% (199/242) and 92% (339/368), respectively, had received ≥1 doses of RV1. Effectiveness of a full series (2 doses) of RV1 against rotavirus diarrhea requiring hospitalization was 54% (95% confidence interval [CI], 23%-73%); 1 dose of RV1 was 48% (95% CI, 1%-72%) effective. Effectiveness was 59% (95% CI, 4%-83%) against rotavirus caused by G2P, the most common (37%) circulating genotype. However, the effectiveness of 2 RV1 doses was significantly higher in children with no undernutrition (VE, 75% [95% CI, 41%-89%]), compared to those with moderate or severe undernutrition (VE, -28% [95% CI, -309% to 60%]) (P= .02). CONCLUSIONS: Routine RV1 vaccination in Botswana showed effectiveness similar to that in clinical trials in Africa, including against a serotype fully heterotypic to the vaccine. Undernutrition may in part explain the lower rotavirus VE in low-income settings.

Two-hundred eighty matched bulk stool and anatomically designed flocked rectal swab samples were collected from children admitted to the hospital with acute diarrhea in Botswana. Their parents were asked about the acceptability of the swab collection method compared with bulk stool sampling. All samples underwent identical testing with a validated 15-target (9 bacterial, 3 viral, and 3 parasite) commercial multiplex PCR assay. The flocked swabs had a 12% higher yield for bacterial pathogen targets (241 versus 212; P = 0.003) compared with that of stool samples, as well as similar yields for viral targets (110 versus 113; P = 0.701) and parasite targets (59 versus 65; P = 0.345). One hundred sixty-four of the flocked swab-stool pairs were also tested with separate laboratory-developed bacterial and viral multiplex assays, and the flocked rectal swabs had a performance that was similar to that seen with commercial assay testing. Almost all parents/guardians found the swabs acceptable. Flocked rectal swabs significantly facilitate the molecular diagnosis of diarrheal disease in children.

Objectives: Data on triage practices of children admitted to Princess Marina Hospital in Gaborone, Botswana is limited. The inpatient triage, assessment, and treatment score was developed for low resource settings to predict mortality in children. We assess its performance among children admitted to Princess Marina Hospital and their demographic, clinical, and risk factors for death. Methods: This was a secondary data analysis of a prospective cohort study comprising 299 children ages 1 month to 13 years admitted June to September 2018. Descriptive statistics, bivariate analysis, and multivariate logistic regression were used. Sensitivity and specificity data were generated for the inpatient triage, assessment, and treatment score. Results: Thirteen children died (13/284, 4.6%). Comorbidity (adjusted odds ratio 4.0, p = 0.020) and high inpatient triage, assessment, and treatment score (adjusted odds ratio 5.0, p = 0.017) increased odds of death. The area under the receiver operating characteristic curve was 0.81. Using inpatient triage, assessment, and treatment cutoff of 4, the sensitivity, specificity, and likelihood ratio were 31%, 94%, and 5.0, respectively. Conclusion: Implementing the inpatient triage, assessment, and treatment score in low resource settings may improve identification, treatment, and evaluation of the sickest children.
RESUMO
OBJECTIVE: Currently clinicians in sub-Saharan Africa have limited access to the Internet, whereas mobile phone access and use is extensive. The University of Pennsylvania in collaboration with the National Library of Medicine launched txt2MEDLINE, a short messaging service (SMS) query of PubMed/MEDLINE, and SMS-optimized clinical guidelines in Botswana. The objective of this project was to establish and evaluate the utility of these tools for clinicians in Botswana. MATERIALS AND METHODS: A local server was established at the University of Botswana that allowed clinicians to send queries and receive results via local (in-country) SMS text messaging on any type of cellular phone. The queries sent via txt2MEDLINE were returned as abbreviated "the bottom line" summaries of abstracts. The 2007 Botswana Treatment Guide was converted into a format that can be queried by SMS. Various types of healthcare workers were recruited to use and evaluate these services. RESULTS: Seventy-six healthcare workers attended training sessions for these services. In the preusage survey, most said they would use the services daily or weekly. During a 4-week trial period, use of these services dropped off dramatically. Participant feedback was collected and indicated that improvements in ease of use would increase the usage. CONCLUSIONS: This pilot project enables clinicians to query and receive PubMed abstract summaries and country-specific clinical guidelines using mobile phones. Feedback offers insight on how to improve this technology so that it can be adopted for long-term use. With further adjustments, these resources may provide an effective working model for other countries where limited Internet access impedes upon patient care.

With the growth of mobile health in recent years, learning through the use of mobile devices (mobile learning [mLearning]) has gained recognition as a potential method for increasing healthcare providers' access to medical information and resources in resource-limited settings. In partnership with the University of Botswana School of Medicine (SOM), we have been exploring the role of smartphone-based mLearning with resident (physicians in specialty training) education. The SOM, which admitted its first class of medical students and residents in 2009, is committed to providing high-level on-site educational resources for resident physicians, even when practicing in remote locations. Seven residents were trained to use an Android-based myTouch 3G smartphone equipped with data-enabled subscriber identity module (SIM) cards and built-in camera. Phones contained locally loaded point-of-care and drug information applications, a telemedicine application that allows for the submission of cases to local mentors, and e-mail/Web access. Surveys were administered at 4 weeks and 8 weeks following distribution of phones. We found that smartphones loaded with point-of-care tools are effectively utilized by resident physicians in resource-limited settings, both for accessing point-of-care medical information at the bedside and engaging in self-directed learning at home.

OBJECTIVES: A disproportionate number of neonatal deaths occur in low/middle-income countries, with sepsis a leading contributor of mortality. In this study, we investigate risk factors for mortality in a cohort of high-risk hospitalised neonates in Botswana. Independent predictors for mortality for infants experiencing either a sepsis or a non-sepsis-related death are described. METHODS: This is a prospective observational cohort study with infants enrolled from July to October 2018 at the neonatal unit (NNU) of Princess Marina Hospital (PMH) in Gaborone, Botswana. Data on demographic, clinical and unit-specific variables were obtained. Neonates were followed to death or discharge, including transfer to another hospital. Death was determined to be infectious versus non-infectious based on primary diagnosis listed on day of death by lead clinician on duty. RESULTS: Our full cohort consisted of 229 patients. The overall death rate was 227 per 1000 live births, with cumulative proportion of deaths of 22.7% (n=47). Univariate analysis revealed that sepsis, extremely low birth weight (ELBW) status, hypoxic ischaemic encephalopathy, critical illness and infants born at home were associated with an increased risk of all-cause mortality. Our multivariate model revealed that critical illness (HR 3.07, 95% CI 1.56 to 6.03) and being born at home (HR 4.82, 95% CI 1.76 to 13.19) were independently associated with all-cause mortality. Low birth weight status was independently associated with a decreased risk of mortality (HR 0.24, 95% CI 0.11 to 0.53). There was a high burden of infection in the cohort with more than half of infants (140, 61.14%) diagnosed with sepsis at least once during their NNU admission. Approximately 20% (n=25) of infants with sepsis died before discharge. Our univariate subanalysis of the sepsis cohort revealed that ELBW and critical illness were associated with an increased risk of death. These findings persisted in the multivariate model with HR 3.60 (95% CI 1.11 to 11.71) and HR 2.39 (95% CI 1 to 5.77), respectively. CONCLUSIONS: High rates of neonatal mortality were noted. Urgent interventions are needed to improve survival rates at PMH NNU and to prioritise care for critically ill infants at time of NNU admission, particularly those born at home and/or of ELBW.

Objectives: Over the past decade, concerning trends in antimicrobial resistance have emerged in Southern Africa. Given a paucity of pediatric data, our objectives were to (1) describe antibiotic utilization trends at a national referral center in Southern Africa and (2) assess the proportion of patients receiving antibiotics appropriately. In addition, risk factors for inappropriate use were explored. Methods: We performed a prospective cohort study on medical and surgical pediatric patients aged below 13 years admitted to the country's tertiary care referral hospital in Gaborone, Botswana. We collected demographics, clinical, laboratory, and microbiology details, in addition to information on antibiotic use. We separately categorized antibiotic prescriptions using the World Health Organization AWaRe Classification of Access, Watch, and Restrict. Results: Our final cohort of 299 patients was 44% female and 27% HIV-exposed; most (68%) were admitted to the General Pediatrics ward. Infections were a common cause of hospitalization in 29% of the cohort. Almost half of our cohort were prescribed at least one antibiotic during their stay, including 40% on admission; almost half (47%) of these prescriptions were deemed appropriate. At the time of discharge, 52 (21%) patients were prescribed an antibiotic, of which 37% were appropriate. Of all antibiotics prescribed, 42% were from the World Health Organization Access antibiotic list, 58% were from the Watch antibiotic list, and 0% were prescribed antibiotics from the Restrict antibiotic list. Univariate analyses revealed that surgical patients were significantly more likely to have inappropriate antibiotics prescribed on admission. Patients who were treated for diseases for which there was a clinical pathway, or who had blood cultures sent at the time of admission were less likely to have inappropriate antibiotics prescribed. On multivariate analysis, apart from admission to the surgical unit, there were no independent predictors for inappropriate antibiotic use, although there was a trend for critically ill patients to receive inappropriate antibiotics. Conclusion: Our study reveals high rates of antibiotic consumption, much of which was inappropriate. Promising areas for antimicrobial stewardship interventions include (1) standardization of management approaches in the pediatric surgical population and (2) the implementation of feasible and generalizable clinical pathways in this tertiary care facility.
RESUMO
INTRODUCTION: The study aim was to determine if rapid enteric diagnostics followed by the provision of targeted antibiotic therapy ('test-and-treat') and/or Lactobacillus reuteri DSM 17938 would improve outcomes in children hospitalised in Botswana with acute gastroenteritis. METHODS: This was a multicentre, randomised, factorial, controlled, trial. Children aged 2-60 months admitted for acute non-bloody diarrhoea to four hospitals in southern Botswana were eligible. Participants were assigned to treatment groups by web-based block randomisation. Test-and-treat results were not blinded, but participants and research staff were blinded to L. reuteri/placebo assignment; this was dosed as 1×108 cfu/mL by mouth daily and continued for 60 days. The primary outcome was 60-day age-standardised height (HAZ) adjusted for baseline HAZ. All analyses were by intention to treat. The trial was registered at Clinicaltrials.gov. RESULTS: Recruitment began on 12 June 2016 and continued until 24 October 2018. There were 66 participants randomised to the test-and-treat plus L. reuteri group, 68 randomised to the test-and-treat plus placebo group, 69 to the standard care plus L. reuteri group and 69 to the standard care plus placebo group. There was no demonstrable impact of the test-and-treat intervention (mean increase of 0.01 SD, 95% CI -0.14 to 0.16 SD) or the L. reuteri intervention (mean decrease of 0.07 SD, 95% CI -0.22 to 0.08 SD) on adjusted HAZ at 60 days. CONCLUSIONS: In children hospitalised for acute gastroenteritis in Botswana, neither a test-and-treat algorithm targeting enteropathogens, nor a 60-day course of L. reuteri DSM 17938, were found to markedly impact linear growth or other important outcomes. We cannot exclude the possibility that test-and-treat will improve the care of children with significant enteropathogens (such as Shigella) in their stool. TRIAL REGISTRATION NUMBER: NCT02803827.

BACKGROUND: A single dose of nevirapine during labor reduces perinatal transmission of human immunodeficiency virus type 1 (HIV-1) but often leads to viral nevirapine resistance mutations in mothers and infants. METHODS: We studied the response to nevirapine-based antiretroviral treatment among women and infants who had previously been randomly assigned to a single, peripartum dose of nevirapine or placebo in a trial in Botswana involving the prevention of the transmission of HIV-1 from mother to child. All women were treated with antenatal zidovudine. The primary end point for mothers and infants was virologic failure by the 6-month visit after initiation of antiretroviral treatment, estimated within groups by the Kaplan-Meier method. RESULTS: Of 218 women who started antiretroviral treatment, 112 had received a single dose of nevirapine and 106 had received placebo. By the 6-month visit after the initiation of antiretroviral treatment, 5.0% of the women who had received placebo had virologic failure, as compared with 18.4% of those who had received a single dose of nevirapine (P=0.002). Among 60 women starting antiretroviral treatment within 6 months after receiving placebo or a single dose of nevirapine, no women in the placebo group and 41.7% in the nevirapine group had virologic failure (P<0.001). In contrast, virologic failure rates did not differ significantly between the placebo group and the nevirapine group among 158 women starting antiretroviral treatment 6 months or more post partum (7.8% and 12.0%, respectively; P=0.39). Thirty infants also began antiretroviral treatment (15 in the placebo group and 15 in the nevirapine group). Virologic failure by the 6-month visit occurred in significantly more infants who had received a single dose of nevirapine than in infants who had received placebo (P<0.001). Maternal and infant findings did not change qualitatively by 12 and 24 months after the initiation of antiretroviral treatment. CONCLUSIONS: Women who received a single dose of nevirapine to prevent perinatal transmission of HIV-1 had higher rates of virologic failure with subsequent nevirapine-based antiretroviral therapy than did women without previous exposure to nevirapine. However, this applied only when nevirapine-based antiretroviral therapy was initiated within 6 months after receipt of a single, peripartum dose of nevirapine.

BACKGROUND: Poor vitamin D status is a global health problem and common in patients with human immunodeficiency virus (HIV) in high-income countries. There is less evidence on prevalence of vitamin D deficiency and nutrition and growth in HIV-infected and -exposed children in low- and middle-income countries. OBJECTIVES: To determine the vitamin D status in Batswana HIV-infected mothers and their children, differences among HIV-infected mothers and between HIV-exposed and -infected infants and children, and associations between vitamin D and disease-related outcomes, nutrition, and growth. METHODS: This was a cross-sectional study of HIV+ mothers and HIV-exposed infants and unrelated children (1-7.9 years). Serum 25-hydroxyvitamin D (25(OH)D) was measured, among other nutritional indicators, for mothers, infants and children. Vitamin D status for HIV-infected mothers and children, and an immune panel was assessed. History of HIV anti-retroviral medications and breastfeeding were obtained. Data were collected prior to universal combination antiretroviral therapy in pregnancy. RESULTS: Mothers (n = 36) had a mean serum 25(OH)D of 37.2±12.4ng/mL; 11% had insufficient (<20ng/mL), 17% moderately low (20.0-29.9ng/mL) and 72% sufficient (≥30ng/mL) concentrations. No infants (n = 36) or children (n = 48) were vitamin D insufficient; 22% of HIV- and no HIV+ infants had moderately low concentrations and 78% of HIV- and 100% of HIV+ infants had sufficient status, 8% of HIV- and no HIV+ children had moderately low concentrations and 92% of HIV- and 100% HIV+ children had sufficient concentrations. HIV+ children had significantly lower length/height Z scores compared to HIV- children. Length/height Z score was positively correlated with serum 25(OH)D in all children (r = 0.33, p = 0.023), with a stronger correlation in the HIV+ children (r = 0.47 p = 0.021). In mothers, serum 25(OH)D was positively associated with CD4% (r = 0.40, p = 0.016). CONCLUSIONS: Results showed a low prevalence of vitamin D insufficiency in Botswana. Growth was positively correlated with vitamin D status in HIV-exposed children, and HIV+ children had poorer linear growth than HIV- children.

In Francistown, Botswana, approximately 40% of pregnant women are HIV positive. PMTCT has been available since 1999, antiretroviral (ARV) therapy since 2001, and 95% of women have antenatal care (ANC) and deliver in hospital. However, in 2002, only 33% of ANC clients were tested for HIV, and not all women with HIV received services. In 2003, we conducted a survey of 504 pregnant and postpartum women to explore reasons for poor program uptake, and interviewed 82 health providers about PMTCT. Most women (95%) believed that all pregnant women should be tested for HIV. In multivariate analysis, factors associated with having an HIV test included being interviewed at an urban site, having a high PMTCT knowledge score, knowing someone receiving PMTCT or ARV therapy, and having a partner who had been tested for HIV. Neither fear of stigma nor resistance from partners were frequent reasons for refusing an HIV test. Providers of HIV services reported discomfort with their knowledge and skills, and 84% believed HIV testing should be routine. Ensuring adequate knowledge about HIV and PMTCT, creating systems whereby HIV-positive women receiving care can educate and support other women, and making HIV testing routine for pregnant women may improve the uptake of HIV testing.

OBJECTIVES: Millions of children die every year from serious childhood illnesses. Most deaths are avertable with access to quality care. Saving Children's Lives (SCL) includes an abbreviated high-intensity training (SCL-aHIT) for providers who treat serious childhood illnesses. The objective of this study was to examine the impact of SCL-aHIT on knowledge acquisition and retention of providers. SETTING: 76 participating centres who provide primary and secondary care in Kweneng District, Botswana. PARTICIPANTS: Doctors and nurses expected by the District Health Management Team to provide initial care to seriously ill children, completed SCL-aHIT between January 2014 and December 2016, submitted demographic data, course characteristics and at least one knowledge assessment. METHODS: Retrospective, cohort study. Planned and actual primary outcome was adjusted acquisition (change in total knowledge score immediately after training) and retention (change in score at 1, 3 and 6 months), secondary outcomes were pneumonia and dehydration subscores. Descriptive statistics and linear mixed models with random intercept and slope were conducted. Relevant institutional review boards approved this study. RESULTS: 211 providers had data for analysis. Cohort was 91% nurses, 61% clinic/health postbased and 45% pretrained in Integrated Management of Childhood Illness (IMCI). A strong effect of SCL-aHIT was seen with knowledge acquisition (+24.56±1.94, p<0.0001), and loss of retention was observed (-1.60±0.67/month, p=0.018). IMCI training demonstrated no significant effect on acquisition (+3.58±2.84, p=0.211 or retention (+0.20±0.91/month, p=0.824) of knowledge. On average, nurses scored lower than physicians (-19.39±3.30, p<0.0001). Lost to follow-up had a significant impact on knowledge retention (-3.03±0.88/month, p=0.0007). CONCLUSIONS: aHIT for care of the seriously ill child significantly increased provider knowledge and loss of knowledge occurred over time. IMCI training did not significantly impact overall knowledge acquisition nor retention, while professional status impacted overall score and lost to follow-up impacted retention.

BACKGROUND: Botswana has high antenatal human immunodeficiency virus (HIV) prevalence (33.4%). The public health system provides free services for prevention of mother to child transmission of HIV (PMTCT) and antiretroviral therapy, which can reduce vertical HIV transmission from 35% to <5%. Infant HIV diagnosis is challenging in resource-limited settings, and HIV prevalence among HIV-exposed infants in Botswana is unknown. Dried blood spot (DBS) polymerase chain reaction (PCR) provides a feasible method to assess PMTCT programs and identify HIV-infected children. METHODS: We trained staff in 15 clinics and a hospital to obtain DBS on HIV-exposed infants age 6 weeks to 17 months receiving routine care. Samples were sent to the national HIV reference laboratory. Roche Amplicor 1.5 DNA PCR testing was performed. RESULTS: Between June-December 2005, 1931 HIV-exposed infants age 6 weeks to 17 months were tested for HIV, of whom 136 (7.0%) were HIV infected. Among infants Assuntos

RESUMO
High mortality among adolescents with HIV reflects delays and failures in the care cascade. We sought to elucidate critical missed opportunities and barriers to care among adolescents hospitalized with HIV at Botswana's tertiary referral hospital. We enrolled all HIV-infected adolescents (aged 10-19 years) hospitalized with any diagnosis other than pregnancy from July 2015 to January 2016. Medical records were reviewed for clinical variables and past engagement in care. Semi-structured interviews of the adolescents (when feasible) and their caregivers explored delays and barriers to care. Twenty-one eligible adolescents were identified and 15 were enrolled. All but one were WHO Clinical Stage 3 or 4. Barriers to diagnosis included lack of awareness about perinatal HIV infection, illness or death of the mother, and fear of discrimination. Barriers to adherence to antiretroviral therapy included nondisclosure, isolation, and mental health concerns. The number of hospitalized HIV-infected adolescents was lower than expected. However, among those hospitalized, the lack of timely diagnosis and subsequent gaps in the care cascade elucidated opportunities to improve outcomes and quality of life for this vulnerable group.
