RESUMO
BACKGROUND: Cervical cancer is a preventable cancer; however, decreasing its prevalence requires early detection and treatment strategies that reduce rates of loss to follow-up. This study explores factors associated with loss to follow-up among HPV-positive women after implementation of a new HPV-based screen-and-treat approach for cervical cancer prevention in Iquitos, Peru. METHODS: We conducted semi-structured interviews with "obstetras" (i.e., midwives) (n = 15) working in cervical cancer prevention and women (n = 24) who were recorded as lost to follow-up after positive HPV results. We used the Health Care Access Barriers Model to guide analyses. We utilized manifest content analysis to describe barriers to follow-up according to the obstetras and thematic analysis to report themes from the women's perspectives. We also report the steps and time taken to contact women. RESULTS: We found an incomplete and fragmented patient monitoring system. This incomplete system, in conjunction with challenges in contacting some of the women, led to structural barriers for the obstetras when attempting to deliver positive results. Women in this study expressed a desire to receive treatment, however, faced cognitive barriers including a lack of understanding about HPV results and treatment procedures, fear or anxiety about HPV or treatment, and confusion about the follow-up process. Women also reported having important work matters as a barrier and reported frequently using natural medicine. Reported financial barriers were minimal. CONCLUSION: This study highlights the barriers to follow-up after implementation of a primary-level HPV-based screen-and-treat approach. While some barriers that have previously been associated with loss to follow-up were not as prominently observed in this study (e.g., financial), we emphasize the need for screen-and-treat programs to focus on strategies that can address incomplete registry systems, structural challenges in results delivery, cognitive barriers in understanding results and treatment, and work-related barriers.

Background: Loss to follow-up (LTFU) from tuberculosis (TB) treatment and care is a significant public health problem. It is important to understand what drives LTFU in children - a population whose treatment and management depend on an adult caregiver - to better provide support services to families affected by TB. Methods: We conducted a prospective cohort study of household contacts in Lima, Peru (2009-12). Using multilevel logistic regression analysis, we explored individual-level characteristics of children and their adult household members with TB disease to identify risk factors for LTFU among children initiated on treatment for TB. Results: A total of 154 child (0-14 years) household contacts were diagnosed with TB and initiated on treatment. While most (n = 133, 86.4%) had a successful outcome, 20 (13.0%) children were LTFU. Six (30.0%) children were LTFU within three months, nine (45.0%) between five to seven months, and three (15.0%) after seven months of treatment being initiated. In univariable analysis, children with index patients above 25 years of age had decreased odds of being LTFU (odds ratio = 0.26; 95% confidence interval = 0.08-0.84) compared to children with index patients 25 years or younger. Conclusions: In this cohort, more than 10% of children sick with TB who were exposed to the disease at home were LTFU. An integrated, family-centred TB prevention and management approach may reduce barriers to a child completing their course of TB treatment.

BACKGROUND: Loss to follow-up (LTFU) among paediatric patients living with HIV presents a significant challenge to the global scale-up of life-saving antiretroviral therapy (ART). OBJECTIVES: This study aims to estimate LTFU incidence and its determinants among children with HIV on ART in Shashemene town public health institutions, Oromia, Ethiopia. DESIGN: A retrospective cohort study from 1 January 2015 to 30 December 2020. SETTING: This study was conducted in Shashemene town, Oromia, Ethiopia. PARTICIPANTS: Medical records of 269 children receiving ART at health facilities in Shashemene town were included. METHODS: Data from patients' medical records were collected using a standardised checklist. EpiData V.3.1 was employed for data entry, while Statistical Package for the Social Sciences (SPSS) V.25 facilitated analysis. The Kaplan-Meier survival curve was used for estimation of survival time. To measure association, adjusted HRs (AHRs) with 95% CIs were calculated. Both bivariable and multivariable Cox proportional hazards regression models were employed to identify predictors of LTFU. RESULTS: Of the 269 children living with HIV included in the final analysis, 43 (16%) were lost to follow-up. The overall incidence rate of LTFU was 3.3 (95% CI 2.4 to 4.4) per 100 child-years of observation. Age less than 5 years (AHR 0.03, 95% CI 0.00 to 0.36), non-orphan status of the child (AHR 0.13, 95% CI 0.05 to 0.34), < 30 min distance to health facility (AHR 0.24, 95% CI 0.08 to 0.73), disclosed HIV status (AHR 0. 32, 95% CI 0.13 to 0.80), history of opportunistic infection (AHR 3.54, 95% CI 1.15 to 10.87) and low CD4 count (AHR 5.17, 95% CI 2.08 to 12.85) were significant predictors of LTFU. CONCLUSION: The incidence rate of LTFU was lower compared with other studies in Ethiopia. This result indicated that age less than 5 years, non-orphans, low CD4, disclosed HIV status and distance from health facility were predictors of LTFU.

INTRODUCTION: Tuberculosis (TB) is a global public health issue. The Southeast Asian region grapples with numerous challenges in TB management, with loss to follow-up (LTFU) emerging as a critical barrier to effective control of the disease. This review synthesised published articles to identify socioeconomic factors contributing to the burden of TB losses for follow-up in Southeast Asia. MATERIALS AND METHODS: This scoping review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework developed by the Joanna Briggs Institute (JBI). A total of 10 studies were identified as eligible from the title and abstract review. The mixed method quality appraisal tool (MMAT) version 2018 was used to assess the quality of the included quantitative studies. RESULTS: The results showed that poverty, unemployment, low education levels, migrant status, community support, male gender, substance abuse, and regional disparities significantly impact the occurrence of TB LTFU in Southeast Asia. CONCLUSION: The findings have significant implications for public health in Southeast Asia. Addressing these socioeconomic barriers through community-based strategies, educational initiatives, and policy reforms is vital for improving treatment outcomes and overall public health.

The purpose of this study is to examine the effect of early incomplete follow-up on overall survival among stage I lung cancer patients. Patients with clinical stage I lung cancer at our institution between 2007 and 2016 were identified (N = 1111). Exclusions included < 18 years of age (N = 2), missing stage or demographics (N = 56), incomplete appointment data or had only one scheduled appointment (N = 351), or did not survive for at least 1 year after diagnosis (N = 120). Missed appointments were defined as unattended follow-up appointments within the first year of diagnosis without an attended appointment in the subsequent 60 days. The primary outcome was the hazard ratio (HR) for death associated per 10% increase in missed oncology follow-up appointments. Univariable and descriptive statistics were performed, and a multivariable landmark Cox regression model was created to examine the effect of missed oncology follow-up on survival. A total of 582 patients were analyzed with median follow-up of 3.2 years and median age of 69 years. On multivariable analysis controlling for age, sex, race, insurance status, and definitive treatment type the HR for death was 1.44 (95% CI 1.05-1.97) for every 10% increase in missed appointments. Incomplete oncologic follow-up may negatively impact overall survival among survivors of early-stage lung cancer.

This retrospective cohort study identified factors associated with loss of follow-up and death due to tuberculosis (TB) in the homeless population (HP) in Brazil, estimating odds ratios (OR) and their 95% confidence intervals (95%CI) by multinomial logistic regression. A total of 3,831 TB cases in this population were analyzed, of which 57.0% had unfavorable outcomes. Loss of follow-up was associated with: history of abandonment (OR=2.38; 95%CI 2.05-2.77), unknown HIV serology (OR=1.79; 95%CI 1.38-2.32), HIV coinfection (OR=1.73; 95%CI 1.46-2.06), drug use (OR=1.54; 95%CI 1.31-1.80), age (OR=0.98; 95%CI 0.97-0.99), mixed clinical form (OR=0.64; 95%CI 0.42-0.97), extrapulmonary form (OR=0.46; 95%CI 0.29-0.73), government beneficiary (OR=0.64; 95%CI 0.50-0.81), and supervised treatment (OR=0.52; 95%CI 0.45-0.60). Regarding death, the following were associated: age (OR=1.03; 95%CI 1.01-1.05), unknown HIV serology (OR=2.39; 95%CI 1.48-3.86), alcohol consumption (OR=1.81; 95%CI 1.27-2.58), and supervised treatment (OR=0.70; 95%CI 0.51-0.96). Overlapping vulnerabilities in the health-disease process of homeless individuals with TB were observed, requiring comprehensive and cross-sectoral care practices.
Esta coorte retrospectiva identificou os fatores associados à perda de seguimento e ao óbito por tuberculose na população em situação de rua no Brasil, estimando-se as odds ratios (OR) e seus intervalos de confiança de 95% (IC95%) por regressão logística multinominal. Analisaram-se 3.831 casos de tuberculose nessa população, dos quais 57,0% tiveram desfechos desfavoráveis. Associaram-se à perda de seguimento: histórico de abandono (OR=2,38; IC95% 2,05-2,77), desconhecimento da sorologia do HIV (OR=1,79; IC95% 1,38-2,32) e coinfecção com HIV (OR=1,73; IC95% 1,46-2,06), uso de drogas (OR=1,54; IC95% 1,31-1,80), idade (OR=0,98; IC95% 0,97-0,99), forma clínica mista (OR=0,64; IC95% 0,42-0,97) e extrapulmonar (OR=0,46; IC95% 0,29-0,73), auxílio de programa governamental (OR=0,64; IC95% 0,50-0,81) e tratamento supervisionado (OR=0,52; IC95% 0,45-0,60). Em relação ao óbito, associaram-se: idade (OR=1,03; IC95% 1,01-1,05), desconhecimento da sorologia do HIV (OR=2,39; IC95% 1,48-3,86), uso de álcool (OR=1,81; IC95% 1,27-2,58) e tratamento supervisionado (OR=0,70; IC95% 0,51-0,96). Percebeu-se a sobreposição de vulnerabilidades no processo saúde-doença das pessoas em situação de rua com tuberculose, demandando práticas cuidativas intersetoriais e integrais.

OBJECTIVES: The objective of this study is to assess the outcomes of children, adolescents and young adults with HIV reported as lost to follow-up, correct mortality estimates for children, adolescents and young adults with HIV for unascertained outcomes in those loss to follow-up (LTFU) based on tracing and linkage data separately using data from the International epidemiology Databases to Evaluate AIDS in Southern Africa. METHODS: We included data from two different populations of children, adolescents and young adults with HIV; (1) clinical data from children, adolescents and young adults with HIV aged ≤24 years from Lesotho, Malawi, Mozambique, Zambia and Zimbabwe; (2) clinical data from children, adolescents and young adults with HIV aged ≤14 years from the Western Cape (WC) in South Africa. Outcomes of patients lost to follow-up were available from (1) a tracing study and (2) linkage to a health information exchange. For both populations, we compared six methods for correcting mortality estimates for all children, adolescents and young adults with HIV. RESULTS: We found substantial variations of mortality estimates among children, adolescents and young adults with HIV reported as lost to follow-up versus those retained in care. Ascertained mortality was higher among lost and traceable children, adolescents and young adults with HIV and lower among lost and linkable than those retained in care (mortality: 13.4% [traced] vs. 12.6% [retained-other Southern Africa countries]; 3.4% [linked] vs. 9.4% [retained-WC]). A high proportion of lost to follow-up children, adolescents and young adults with HIV had self-transferred (21.0% and 47.0%) in the traced and linked samples, respectively. The uncorrected method of non-informative censoring yielded the lowest mortality estimates among all methods for both tracing (6.0%) and linkage (4.0%) approaches at 2 years from ART start. Among corrected methods using ascertained data, multiple imputation, incorporating ascertained data (MI(asc.)) and inverse probability weighting with logistic weights were most robust for the tracing approach. In contrast, for the linkage approach, MI(asc.) was the most robust. CONCLUSIONS: Our findings emphasise that lost to follow-up is non-ignorable and both tracing and linkage improved outcome ascertainment: tracing identified substantial mortality in those reported as lost to follow-up, whereas linkage did not identify out-of-facility deaths, but showed that a large proportion of those reported as lost to follow-up were self-transfers.

Achieving high follow-up rates after smoking cessation interventions (SCIs) is a general challenge. The aim of this study was to identify preferences among patients and therapists for improving follow-up rates and to assess smoking status at 6 months among patients lost to follow-up. From the Danish STOPbase for Tobacco and Nicotine, which collects data on SCI across health care, 20 representative patients lost to follow-up by routine procedures were identified together with 11 therapists. All participated in individual semi-structured phone interviews, which for patients also included 6-month smoking status. Deductive and inductive analyses were performed. Four themes emerged from the analyses with several subthemes, all regarding contacts. Both patients and therapists preferred to intensify the follow-up process by boosting it with additional attempts and using voice messages, e-mail and/or SMS, calling at specified times of the day and avoiding calls from unknown numbers. In addition, some patients mentioned that they were busy or were not carrying their mobile devices at the time of a call as a barrier. Some therapists mentioned that barriers could include an expectation of relapse, but also a poor mental state, the time of day and patient fear of public systems. Among the patients originally lost to follow-up, 35% (95% CI 16%-59%) experienced continuous smoking cessation for 6 months, and the overall national rate was 22% (21.6-23.3%). In conclusion, both patients and therapists preferred intensified follow-up. The 6-month smoking status for patients lost to follow-up seemed to be similar to that of the routinely followed-up patients. These findings will be examined experimentally in a larger study.

Despite expanded and successful antiretroviral therapy program coverage, a large proportion of people drop out at different stages along their treatment course. As a result, treatment gains do not reach a large proportion of these groups. It has been demonstrated that around half of the patients who test Human immunodeficiency virus (HIV) positive in Sub-Saharan Africa are lost between testing and being considered for eligibility for therapy. The purpose of this study was to determine the factors that influence patients on antiretroviral therapy who lost to follow up in HIV treatment clinics in Asunafo South District, Ahafo Region. We used phenomenological qualitative research approach in conducting this study. Purposive sampling was used to select respondents, while key informant interview was used to collect the data. The major identified challenges in carrying out follow-up visits of patients on antiretroviral therapy were wrong addresses and phone numbers of clients, coupled with poor telecommunication networks, geographical relocation of clients, poor documentation of patients' information, and non-availability of means of transport. The preferred reengagement strategies identified in this study were: supply of drugs through home visits, intensive education, engaging the services of community-based surveillance officers, enhanced regular phone calls visits, adoption and use of an integrated antiretroviral therapy clinic, intensified education on HIV, and involvement of religious leaders. In conclusion, all clinicians and stakeholders should consider the identified challenges and reengagement strategies when providing antiretroviral services.

INTRODUCTION: Inpatient and outpatient evaluation is important for management of temporal bone trauma due to the possible otologic complications that can result. However, there is limited literature on follow up rates following temporal bone fracture. This study aimed to determine the proportion of patients lost to follow up after sustaining temporal bone fractures and identify factors associated with loss to follow up. METHODS: Retrospective review of adult patients who sustained temporal bone fractures at a level I trauma center from January 1, 2019 to January 1, 2024 was completed (IRB H-44161). The primary outcome included prevalence of patient loss to follow up. Secondary variables included initial radiographic and exam findings, otologic complications, and demographic characteristics. Patients who were seen in follow up and lost to follow up were compared, and odds of loss to follow up was calculated. RESULTS: Sixty-nine patients met inclusion criteria for this study, of which 30 patients (43.5%) were lost to follow up. Patients who were White had a significantly lower odds of loss to follow up than those who were not White (OR = 0.2506 (95% CI: 0.0706, 0.8067, P = .0024). While need for acute management was not significantly different between the groups, a significantly lower proportion of patients who were intubated on presentation (P = .0091), had abnormal otoscopic exam (P = .0211), and had otologic complications (P = .0056) were lost to follow up. CONCLUSION: Almost half of patients who sustained temporal bone fractures, including a significantly higher odds of minority race/ethnicity patients, were lost to follow up.

Objective: To understand the loss to follow-up of children born to pregnant women with HIV infection (HIV-exposed children) and analyze its influencing factors in China in 2019. Methods: The data were collected from the follow-up records of pregnant women with HIV infection and their children reported by the national "Management Information System for the Prevention of HIV, syphilis and Hepatitis B Mother-to-Child Transmission" in 2019. HIV-exposed children were defined as those who were not followed up after birth or who were not followed up at 18 months of age and who were not followed up at 21 months of age. The univariate and multivariate influencing factors of loss to follow-up of children born to HIV-infected pregnant women were analyzed by χ2 test and logistic regression model. SPSS 25.0 software was used for statistical analysis. Results: The number of HIV-infected pregnant women was 5 039, the number of live-born children was 5 035, the number of loss to follow-up children within 18 months of age was 283, and the loss to follow-up rate children was 5.62%(283/5 035). The results of multivariate logistic regression analysis showed that the rate of loss to follow-up of exposed children born to pregnant women who worked as farmers (animal husbandry and fishery) (aOR=0.34, 95%CI: 0.22-0.53), unmarried (aOR=0.47, 95%CI: 0.24-0.93), first marriage (aOR=0.38, 95%CI: 0.22-0.67), remarriage (aOR=0.36, 95%CI: 0.20-0.67) and cohabiting (aOR=0.47, 95%CI: 0.23-0.97), and knew they had HIV infection before this pregnancy (aOR=0.53, 95%CI: 0.40-0.70) was lower. Han nationality (aOR=1.52, 95%CI: 1.09-2.13), primary school (aOR=2.06, 95%CI: 1.10-3.89) and junior middle school (aOR=1.81, 95%CI: 1.03-3.17) educational level, non-use of antiviral drugs (aOR=6.21, 95%CI: 4.32-8.93) and delivery in township (street) level midwifery institutions (aOR=5.72, 95%CI: 1.61-20.27) had higher rates of loss to follow-up among infants born to HIV-infected pregnant women. Conclusions: HIV-exposed children still have a specific rate of loss to follow-up in China in 2019. In order to further reduce the rate of loss to follow-up, it is of great significance to improve the detection rate of HIV before pregnancy and the rate of antiviral drugs used in pregnant women with HIV infection, which is of great significance for the effective implementation of comprehensive intervention measures of prevention of mother-to-child transmission of HIV.

Despite the effectiveness of antiretroviral therapy (ART), human immunodeficiency virus (HIV) infection remains a global public health concern. However, weaknesses in its management regarding access to integrated HIV care include treatment gaps and loss to follow-up (LTFU) from antiretroviral treatment (ART). This study aimed to characterize the epidemiological and clinical profiles of people living with HIV/AIDS (PLHA) in LTFU from HIV care in Campo Grande, Central Brazil. This retrospective cross-sectional study was conducted between January 2021 and April 2022 using secondary data from PLHA who had LTFU in Campo Grande. A total of 852 patients with PLHA were included in this study. The majority of participants in LTFU were male (63.1%), had a CD4 cell count > 200 cells/mm3 (68.2%), and had been treated for ≥ 3 months (86.4%). Only 287 (33.7%) participants had undetectable HIV viral load. Of the total number of patients who returned to treatment during the study period, 448 (54.3%) were LTFU-positive. The tracking strategy was not applied to 556 (65.26%) patients, and 44.4% of the participants had been in spontaneous demand. These results highlight the relevance of patient-centered interventions and the need to ensure early treatment and promote retention in care systems with consequent viral suppression, impacting the healthcare indicators of the population, with emphasis on health managers and stakeholders in HIV care.

OBJECTIVE: HIV Pre-Exposure Prophylaxis (PrEP) has been used in France since 2016. Its effectiveness is no longer to be demonstrated. However, follow-up and adherence remain the main pitfalls. The main objective of this study was to identify factors associated with persistence or loss of PrEP follow-up. DESIGN: An historic cohort of PrEP users was compiled from the database of consultations in the Indre-et-Loire dedicated sexual health centers (CeGIDD) from June 2016 to June 2021. METHODS: Kaplan-Meier curves were performed to compare the group of persistent PrEP users to the discontinuation group. Factors associated with PrEP discontinuation were identified using Cox modelling, considering time-dependent variables. Final variables included in the model were selected based on the Akaike Information Criterion (AIC) and clinical relevance. RESULTS: Over the period, 568 PrEP users were included in the cohort. Median follow-up was 2.3 years. A quarter of users were lost to follow-up within 3 months after PrEP initiation. Sexual risk reduction AIDS community-based support (HR = 0.65[0.42;0.99]), being in a couple (HR = 0.51[0.38;0.68]), and history of syphilis (HR = 0.57[0.40;0.81]) were significantly associated with persistence of follow-up. Remote consultations (HR = 2.74[1.63;4.61]), chemsex practices (HR = 2.01[1.29;3.14]), and side effects (HR=1.72[1.03;2.88]) were significantly associated with a loss of follow-up. CONCLUSION: These results suggest that more sexual risk reduction AIDS community-based counseling could be a key, necessary for supporting PrEP users in their follow-up pathway. Indeed, AIDS community-based support could be used to build a basis for developing safe pathways. Remote consultations could represent a response to the issue of access to PrEP. To create a significant impact on global HIV incidence, the PrEP offer must be extended, and at-risk PrEP users supported to maintain PrEP use.

INTRODUCTION: Loss to follow-up (LTFU) distorts results of randomized controlled trials (RCTs). Understanding trial characteristics that contribute to LTFU may enable investigators to anticipate the extent of LTFU and plan retention strategies. The objective of this systematic review and meta-analysis was to investigate the extent of LTFU in surgical RCTs and evaluate associations between trial characteristics and LTFU. METHODS: MEDLINE, Embase, and PubMed Central were searched for surgical RCTs published between January 2002 and December 2021 in the 30 highest impact factor surgical journals. Two-hundred eligible RCTs were randomly selected. The pooled LTFU rate was estimated using random intercept Poisson regression. Associations between trial characteristics and LTFU were assessed using metaregression. RESULTS: The 200 RCTs included 37,914 participants and 1307 LTFU events. The pooled LTFU rate was 3.10 participants per 100 patient-years (95% confidence interval [CI] 1.85-5.17). Trial characteristics associated with reduced LTFU were standard-of-care outcome assessments (rate ratio [RR] 0.17; 95% CI 0.06-0.48), surgery for transplantation (RR 0.08; 95% CI 0.01-0.43), and surgery for cancer (RR 0.10; 95% CI 0.02-0.53). Increased LTFU was associated with patient-reported outcomes (RR 14.21; 95% CI 4.82-41.91) and follow-up duration ≥ three months (odds ratio 10.09; 95% CI 4.79-21.28). CONCLUSIONS: LTFU in surgical RCTs is uncommon. Participants may be at increased risk of LTFU in trials with outcomes assessed beyond the standard of care, surgical indications other than cancer or transplant, patient-reported outcomes, and longer follow-up. Investigators should consider the impact of design on LTFU and plan retention strategies accordingly.

BACKGROUND: Multidrug-resistant tuberculosis is a type of tuberculosis that is resistant to at least the first-line antituberculosis drugs namely, rifampicin and isoniazid. However, most of these studies were limited only to a single hospital. Therefore, this study aimed to identify the determinants of multidrug-resistant tuberculosis among adults undergoing treatment for tuberculosis in the Tigray region of Ethiopia. METHODS: Hospital-based unmatched case-control study was conducted from 1 April 2019 to 30 June 2019. A simple random sampling method was used to select the required sample size. Variables at a p value less than 0.25 in bivariate analysis were entered into a multivariable analysis to identify the determinant factors of multidrug-resistant tuberculosis. Finally, the level of significance was declared at p<0.05. RESULTS: Rural residence (adjusted OR (AOR) 2.54; 95% CI 1.34 to 4.83), HIV (AOR 4.5; 95% CI 1.4 to 14.2), relapse (AOR 3.86; 95% CI 1.98 to 7.5), return after lost follow-up (AOR 6.29; 95% CI 1.64 to 24.2), treatment failure (AOR 5.87; 95% CI 1.39 to 24.8) were among the determinants of multidrug-resistant tuberculosis. CONCLUSION: Rural residence, HIV, relapses, return after lost follow-up and treatment failure were the identified determinant factors of multidrug-resistance tuberculosis.

BACKGROUND: At the end of 2022, globally, only 46% of children (aged 0-14 years) on ART had suppressed viral loads. Viral load suppression is crucial to reduce HIV-related deaths. To suppress the viral load at the expected level, children must be retained in ART treatment. Nevertheless, lost to follow-up from ART treatment continues to be a global challenge, particularly, in developing countries. Previously, primary studies were conducted in Ethiopia to assess the incidence of lost to follow-up among HIV-positive children on ART treatment. However, variations have been seen among the studies. Therefore, this systematic review and meta-analysis aimed to estimate the pooled incidence of lost to follow-up among HIV-positive children on ART and identify its associated factors in Ethiopia. METHODS: We searched PubMed, HINARI, Science Direct, Google Scholar, and African Journals Online to obtain articles published up to November 20, 2023. Critical appraisal was done using the Joanna Briggs Institute checklist. Heterogeneity was identified using I-square statistics. Funnel plot and Egger's tests were used to identify publication bias. Data was presented using forest plots and tables. Random and fixed-effect models were used to compute the pooled estimate. RESULTS: Twenty-four studies were included in the final analysis. The pooled incidence of lost to follow-up among HIV-positive children on ART was 2.79 (95% CI: 1.99, 3.91) per 100-child-year observations. Advanced HIV disease (HR: 2.20, 95% CI: 1.71, 2.73), having opportunistic infection (HR: 2.59, 95% CI: 1.39; 4.78), fair or poor ART treatment adherence (HR: 2.92, 95% CI: 1.31; 6.54) and children aged between 1-5 years (HR: 2.1,95% CI: 1.44; 2.95) were factors associated with lost to follow up among HIV positive children on ART. CONCLUSIONS: The overall pooled incidence of lost to follow-up among HIV-positive children on ART is low in Ethiopia. Therefore, counseling on ART drug adherence should be strengthened. Moreover, emphasis has to be given to children with advanced HIV stage and opportunistic infection to reduce the rate of lost to follow up among HIV-positive children on ART. TRIAL REGISTRATION: Registered in PROSPERO with ID: CRD42024501071.

BACKGROUND: Identifying patients at increased risk of loss to follow-up (LTFU) is key to developing strategies to optimize the clinical management of tuberculosis (TB). The use of national registry data in prediction models may be a useful tool to inform healthcare workers about risk of LTFU. Here we developed a score to predict the risk of LTFU during anti-TB treatment (ATT) in a nationwide cohort of cases using clinical data reported to the Brazilian Notifiable Disease Information System (SINAN). METHODS: We performed a retrospective study of all TB cases reported to SINAN between 2015 and 2022; excluding children (< 18 years-old), vulnerable groups or drug-resistant TB. For the score, data before treatment initiation were used. We trained and internally validated three different prediction scoring systems, based on Logistic Regression, Random Forest, and Light Gradient Boosting. Before applying our models we splitted our data into training (~ 80% data) and test (~ 20%) sets, and then compared the model metrics using the test data set. RESULTS: Of the 243,726 cases included, 41,373 experienced LTFU whereas 202,353 were successfully treated. The groups were different with regards to several clinical and sociodemographic characteristics. The directly observed treatment (DOT) was unbalanced between the groups with lower prevalence in those who were LTFU. Three models were developed to predict LTFU using 8 features (prior TB, drug use, age, sex, HIV infection and schooling level) with different score composition approaches. Those prediction scoring systems exhibited an area under the curve (AUC) ranging between 0.71 and 0.72. The Light Gradient Boosting technique resulted in the best prediction performance, weighting specificity and sensitivity. A user-friendly web calculator app was developed ( https://tbprediction.herokuapp.com/ ) to facilitate implementation. CONCLUSIONS: Our nationwide risk score predicts the risk of LTFU during ATT in Brazilian adults prior to treatment commencement utilizing schooling level, sex, age, prior TB status, and substance use (drug, alcohol, and/or tobacco). This is a potential tool to assist in decision-making strategies to guide resource allocation, DOT indications, and improve TB treatment adherence.

OBJECTIVES: Periodic imaging follow-up for patients with unruptured intracranial aneurysms (UIA) is crucial, as studies indicate higher rupture risk with aneurysm growth. However, few studies address patient adherence to follow-up recommendations. This study aims to identify compliance rates and factors influencing follow-up adherence. METHODS: Patients with a UIA were identified from our institution's database from 2011-2021. Follow-up imaging (CT/MR Angiogram) was advised at specific intervals. Patients were categorized into compliant and non-compliant groups based on first-year compliance. Factors contributing to compliance were assessed through multivariate logistic regression. Phone interviews were conducted with non-compliant patients to understand reasons for non-adherence. RESULTS: Among 923 UIA diagnosed patients, 337 were randomly selected for analysis. The median follow-up period was 1.4 years, with a 42% first-year compliance rate. The mean aneurysm size was 3.3 mm. Five patients had a rupture during follow-up, of which 4 died. Compared with patients consulting specialists at the initial diagnosis, those seen by non-specialists exhibited lower compliance (OR 0.25, p < 0.001). Loss to follow-up was greatest during transition from emergency service to specialist appointments. Patients who spoke languages other than English exhibited poorer compliance than those speaking English (OR 0.20, p = 0.01). CONCLUSIONS: Significant amounts of UIA patients at low rupture risk were lost to follow-up before seeing UIA specialists. Main non-compliance factors include inadequate comprehension of follow-up instructions, poor care transfer from non-specialists to specialist, and insurance barriers.

OBJECTIVE: Evaluate the effect of three multimonth dispensing (3MMD) of antiretroviral therapy (ART) on HIV care retention in southern Mozambique. DESIGN: Retrospective cohort study. METHODS: We analyzed routine health data from people with HIV (PWH) aged 10 years old and older who started ART between January 2018 and March 2021. Individuals were followed until December 2021. Cox proportional-hazards models were used to compare attrition (lost to follow-up, death, and transfer out) between 3MMD and monthly ART dispensing. Results were stratified by time on ART before 3MMD enrolment: 'early enrollers' (<6âmonths on ART) and 'established enrollers' (≥6âmonths on ART), and age groups: adolescents and youth (AYLHIV) (10-24âyears) and adults (≥25âyears). RESULTS: We included 7378 PWH (25% AYLHIV, 75% adults), with 59% and 62% enrolled in 3MMD, respectively. Median follow-up time was 11.3 [interquartile range (IQR): 5.7-21.6] months for AYLHIV and 10.2 (IQR: 4.8-20.9) for adults. Attrition was lower in PWH enrolled in 3MMD compared with monthly ART dispensing, in both established (aHR AYLHIVâ=â0.65; 95% CI: 0.54-0.78 and aHR adultsâ=â0.50; 95% confidence interval (CI): 0.44-0.56) and early enrollers (aHR AYLHIVâ=â0.70; 95% CI: 0.58-0.85 and aHR adultsâ=â0.63; 95% CI: 0.57-0.70). Among individuals in 3MMD, male gender (aHRâ=â1.30; 95% CI: 1.18-1.44) and receiving care in a medium-volume/low-volume healthcare facility (aHRâ=â1.18; 95% CI: 1.03-1.34) increased attrition risk. Conversely, longer ART time before 3MMD enrolment (aHRâ=â0.93; 95% CI: 0.92-0.94 per 1 month increase) and age at least 45âyears (aHRâ=â0.77, 95% CI: 0.67-0.89) reduced risk of attrition. CONCLUSION: 3MMD improves retention in care compared with monthly dispensing among established and early enrollers, although to a lesser extent among the latter.
