Rapid Initiation of Antiretroviral Therapy Under the Treat-All Policy Reduces Loss to Follow-Up and Virological Failure in Routine Human Immunodeficiency Virus Care Settings in China: A Retrospective Cohort Study (2016-2022).

Following the World Health Organization's guidelines for rapid antiretroviral therapy (ART) initiation [≤7 days after human immunodeficiency virus (HIV) diagnosis], China implemented Treat-All in 2016 and has made significant efforts to provide timely ART since 2017. This study included newly diagnosed HIV adults from Tianjin, China, between 2016 and 2022. Our primary outcome was loss to follow-up (LTFU) at 12 months after enrollment. The secondary outcome was 12-month virological failure. The association between rapid ART and LTFU, as well as virological failure, was assessed via Cox regression and logistic regression. A total of 896 (19.1%) of 4688 participants received ART ≤7 days postdiagnosis. The rate of rapid ART has increased from 7.5% in 2016 to 33.3% by 2022. The rapid ART group had an LTFU rate of 3.3%, as opposed to 5.0% in the delayed group. The rapid ART group had a much reduced virological failure rate (0.6% vs. 1.8%). Rapid ART individuals had a reduced likelihood of LTFU [adjusted hazard ratio: 0.65, 95% confidence intervals (CI): 0.44-0.96] and virological failure (adjusted odds ratio: 0.35, 95% CI: 0.12-0.80). The real-world data indicated that rapid ART is practicable and beneficial for Chinese people with HIV, providing evidence for its widespread implementation and scaling up.

Self-transfers, Hospital Admissions and Mortality Among Children and Adolescents Lost to Follow-up From Antiretroviral Therapy Programs in the Western Cape, South Africa Between 2004 and 2019: Linkage to Provincial Records.

BACKGROUND: Pediatric programs face a high rate of loss to follow-up (LTFU) among children and adolescents living with HIV (CAHIV). We assessed true outcomes and predictors of these among CAHIV who were LTFU using linkage to the Western Cape Provincial Health Data Centre at Western Cape sites of the International epidemiology Databases to Evaluate AIDS-Southern Africa collaboration. METHODS: We examined factors associated with self-transfer, hospital admission and mortality using competing risks regression in a retrospective cohort of CAHIV initiating antiretroviral therapy <15 years old between 2004 and 2019 and deemed LTFU (no recorded visit at the original facility for ≥180 days from the last visit date before database closure and not known to have officially transferred out or deceased). RESULTS: Of the 1720 CAHIV deemed LTFU, 802 (46.6%) had self-transferred and were receiving care elsewhere within the Western Cape, 463 (26.9%) had been hospitalized and 45 (2.6%) CAHIV had died. The overall rates of self-transfer, hospitalization, mortality and LTFU were 9.4 [95% confidence interval (CI): 8.8-10.1], 5.4 (95% CI: 5.0-6.0), 0.5 (95% CI: 0.4-0.7) and 4.8 (95% CI: 4.4-5.3) per 100 person-years respectively. Increasing duration on antiretroviral therapy before LTFU was associated with self-transfers while male sex, older age at last visit (≥10 years vs. younger) were associated with hospital admission and immune suppression at last visit was associated with 5 times higher mortality. CONCLUSIONS: Nearly half of CAHIV classified as LTFU had self-transferred to another health facility, a quarter had been hospitalized and a small proportion had died.

Estimating the mortality risk correcting for high loss to follow-up among female sex workers with HIV in Durban, South Africa, 2018-2021.

PURPOSE: This study assesses risk factors of loss to follow-up (LTFU) and estimates mortality risk among female sex workers (FSW) with HIV in Durban, South Africa, in 2018-2021. METHODS: We used data from the Siyaphambili trial, which evaluated strategies for improved viral suppression. FSW with HIV aged ≥ 18 years with viral load ≥ 50 copies/mL were followed up for 18 months. LTFU was defined as absence from study or intervention visits for 6 months. We traced LTFU participants by calling/in-person visit attempts to ascertain their vital status. We used Cox regression to determine risk factors of LTFU and inverse probability of tracing weights to correct mortality risk. RESULTS: Of 777 participants, 10 (1.3%) had died and 578 (74.4%) were initially LTFU. Among those LTFU, 36.3% (210/578) were traced successfully, with 6 additional deaths ascertained. Recent physical and sexual violence, and non-viral suppression were associated with increased LTFU. The unweighted and weighted 18-month mortality risks were 2.4% (95% CI: 0.8%-3.9%) and 3.7% (95% CI: 1.8%-5.9%), respectively. CONCLUSIONS: LTFU is common among FSW with HIV in South Africa with additional investigation of vital status demonstrating under-ascertained mortality. These data suggest the need for comprehensively addressing risks for mortality among FSW.

Patients Lost to Follow-up After Injury: Who are They and What are Their Long-Term Outcomes?

INTRODUCTION: Trauma patients are at high risk for loss to follow-up (LTFU) after hospital discharge. We sought to identify risk factors for LTFU and investigate associations between LTFU and long-term health outcomes in the trauma population. METHODS: Trauma patients with an Injury Severity Score ≥9 admitted to one of three Level-I trauma centers, 2015-2020, were surveyed via telephone 6 mo after injury. Univariate and multivariate analyses were performed to assess factors associated with LTFU and several long-term outcomes. RESULTS: Of 3609 patients analyzed, 808 (22.4%) were LTFU. Patients LTFU were more likely to be male (71% versus 61%, P = 0.001), Black (22% versus 14%, P = 0.003), have high school or lower education (50% versus 42%, P = 0.003), be publicly insured (23% versus 13%, P < 0.001), have a penetrating injury (13% versus 8%, P = 0.006), have a shorter length of stay (3.64 d ± 4.09 versus 5.06 ± 5.99, P < 0.001), and be discharged home without assistance (79% versus 50%, P < 0.001). In multivariate analyses, patients who followed up were more likely to require assistance at home (6% versus 11%; odds ratio [OR] 2.23, 1.26-3.92, P = 0.005), have new functional limitations (11% versus 26%; OR 2.91, 1.97-4.31, P = < 0.001), have daily pain (30% versus 48%; OR 2.11, 1.54-2.88, P = < 0.001), and have more injury-related emergency department visits (7% versus 10%; OR 1.93, 1.15-3.22, P = 0.012). CONCLUSIONS: Vulnerable populations are more likely to be LTFU after injury. Clinicians should be aware of potential racial and socioeconomic disparities in follow-up care after traumatic injury. Future studies investigating improvement strategies in follow-up care should be considered.

Mortality Among HIV-Infected Adults on Antiretroviral Therapy in Southern Uganda.

BACKGROUND: Monitoring and evaluation of clinical programs requires assessing patient outcomes. Numerous challenges complicate these efforts, the most insidious of which is loss to follow-up (LTFU). LTFU is a composite outcome, including individuals out of care, undocumented transfers, and unreported deaths. Incorporation of vital status information from routine patient outreach may improve the mortality estimates for those LTFU. SETTINGS: We analyzed routinely collected clinical and patient tracing data for individuals (15 years or older) initiating antiretroviral treatment between January 2014 and December 2018 at 2 public HIV care clinics in greater Rakai, Uganda. METHODS: We derived unadjusted mortality estimates using Kaplan-Meier methods. Estimates, adjusted for unreported deaths, applied weighting through the Frangakis and Rubin method to represent outcomes among LTFU patients who were successfully traced and for whom vital status was ascertained. Confidence intervals were determined through bootstrap methods. RESULTS: Of 1969 patients with median age at antiretroviral treatment initiation of 31 years (interquartile range: 25-38), 1126 (57.2%) were female patients and 808 (41%) were lost. Of the lost patients, 640 patient files (79.2%) were found and reviewed, of which 204 (31.8%) had a tracing attempt. Within the electronic health records of the program, 28 deaths were identified with an estimated unadjusted mortality 1 year after antiretroviral treatment initiation of 2.5% (95% CI: 1.8% to 3.3%). Using chart review and patient tracing data, an additional 24 deaths (total 52) were discovered with an adjusted 1-year mortality of 3.8% (95% CI: 2.6% to 5.0%). CONCLUSIONS: Data from routine outreach efforts by HIV care and treatment programs can be used to support plausible adjustments to estimates of client mortality. Mortality estimates without active ascertainment of vital status of LTFU patients may significantly underestimate program mortality.

Incidence and predictors of loss to follow-up among Ethiopian children on antiretroviral therapy: a systematic review and meta-analysis.

INTRODUCTION: Loss of follow-up (LTFU) from ART regular follow-up is one of the key acknowledged causes for the development of ART-resistant virus strains currently. It becomes a major weakness for the successful implementation of HIV care and treatment programs mainly in Sub-Saharan Africa but also globally. About 20-40% of children on ART loss their regular ART follow-up annually. Because of the inconsistency of the prior publications' findings, policymakers, programmers, and healthcare providers find it difficult to intervene. Hence, this study was conducted to provide a pooled incidence and identify the predictors of LTFU among children on ART in Ethiopia. METHODS: Articles were searched from PubMed/ MEDLINE, CINAHL, EMBASE, Google Scholar, and Science Direct, as well as organizational records and websites. This review included both retrospective and prospective follow-up studies published in English. The data were extracted using Microsoft Excel and exported into Stata™ Version 17.0 for further processing and analysis. The presence of heterogeneity was assessed using forest plots with the I2 test. To identify the source of heterogeneity subgroup analysis, meta-regression, publication bias, and sensitivity analysis were computed. The pooled incidence of LTFU was estimated using a random effects meta-analysis model with the DerSimonian-laired method. To identify the predictors, a 95% confidence interval with relative risk was used to declare the presence or absence of an association. RESULTS: In this systematic review and Meta-analysis, nine studies with a total of 3336 children were included. The pooled incidence of LTFU from ART was 5.83 (95% CI: 3.94, 7.72) per 100 children-years of observation with I2: 83% & p-value < 0.001. Those children who were from rural were had a 1.65 (95% CI: 1.06, 2.52) times higher chance of getting LTFU when compared with their counterparts. Children who had poor ART adherence had a 2.03 (95% CI: 1.23, 3.34) times higher chance of experiencing LTFU of ART than children having good ART adherence. CONCLUSIONS: Among Ethiopian children on ART, one out of 167 had the risk of experiencing LTFU. Being rural dwellers and having poor ART adherence were the identified predictors of LTFU. Close follow-up and phone message text should be used to have good ART adherence among rural dwellers to meet the predetermined goal of ART.

Predicting Lost to Follow-Up Status Using an Adolescent HIV Psychosocial Attrition Risk Assessment Tool: Results From a Mixed Methods Prospective Cohort Study in Uganda.

BACKGROUND: Low retention in care for adolescents living with HIV (ALHIV) has been a key driver of suboptimal viral load suppression rates in Uganda. The objective of this study was to develop a psychosocial risk assessment tool and evaluate its ability to predict the risk of attrition of ALHIV between the ages 15 and 19 years. SETTING: The study was conducted in 20 facilities in Central and Western Uganda from August 2021 through July 2022. METHODS: A mixed methods prospective cohort study was conducted in two phases. In the first phase, the Adolescent Psychosocial Attrition Risk Assessment tool was developed and revised using feedback from focus group discussions and interviews. In the second phase, the ability of the Adolescent Psychosocial Attrition Risk Assessment tool to predict attrition among ALHIV was evaluated using diagnostic accuracy tests. RESULTS: A total of 597 adolescents between the ages 15 and 19 years were enrolled, of which 6% were lost to follow-up at the end of the study period. A 20-question tool was developed, with 12 questions being responded to affirmatively by >50% of all participants. Using a cut-off score of 6 or more affirmative answers translated to an area under the curve of 0.58 (95% CI: 0.49 to 0.66), sensitivity of 55% (95% CI: 36% to 72%), and specificity of 61% (95% CI: 56% to 65%). CONCLUSION: Although the Adolescent Psychosocial Attrition Risk Assessment tool was not effective at predicting lost to follow-up status among ALHIV, the tool was useful for identifying psychosocial issues experienced by ALHIV and may be appropriate to administer during routine care visits to guide action.

CHARACTERISTICS OF PARTICIPANTS IN DIABETIC RETINOPATHY CLINICAL RESEARCH CLINICAL TRIALS WHO WERE LOST TO FOLLOW-UP.

PURPOSE: Our study describes the racial/ethnic composition and the broad health status/severity of disease of the cohorts of Diabetic Retinopathy Clinical Research clinical trials and compares the rates of noncompletion of the trial with the first data report (lost to follow-up). METHODS: This study is a retrospective cohort study of participants in Diabetic Retinopathy Clinical Research Retina Network clinical trials who met our inclusion criteria. The primary outcome was the lost to follow-up rates and their associated risk factors. RESULTS: Eight clinical trials with 3,492 participants met our inclusion criteria. Participants who were lost to follow-up were more likely to be younger, Hispanic or Black, had Type 1 diabetes mellitus, had worse baseline best-corrected visual acuity, had higher hemoglobin A1c, had higher blood pressure, and had proliferative diabetic retinopathy (PDR) (Diabetic Retinopathy Severity Score >66). CONCLUSION: Participants who were lost to follow-up during Diabetic Retinopathy Clinical Research clinical trials tended to be younger, Hispanic or Black, and had worse diabetes and hypertension. This study highlights the importance of ensuring that a representative population is maintained through the end of the study period.

A qualitative exploration of tuberculosis patients who were lost to follow-up in Malaysia.

BACKGROUND: Loss to follow-up (LTFU) is an unsuccessful treatment outcome for tuberculosis (TB) patients. In Malaysia, LTFU affects around 1 in 20 TB patients. Integration of qualitative research methods and evidence will provide a better understanding of LTFU and its underlying issues. In this study, we qualitatively explored TB patients' experiences in receiving treatment and their reasons for leaving TB care. METHOD: In-depth interviews of 15 patients with a history of LTFU were conducted from January to September 2020. Interview guides were developed to explore TB patients' experiences while receiving treatment, including challenges faced and reasons for treatment interruption. Data were thematically analysed using the framework method. RESULTS: We identified 11 emerging themes that occurred at four levels of interaction with TB patients. First, at the patient personal level, TB beliefs referring to patients' perception of illness and wellness, patients' perceived role of traditional and complementary medicine, and substance abuse were important. Second, the healthcare system and treatment factors that were highlighted included the organisation of care and treatment, interaction with healthcare professionals, particularly in communication and counselling, and TB medications' side effects. Third, structural factors including financial burden, logistical and transportation issues and work-related factors were identified to be barriers to treatment continuation. Fourth, the interpersonal level interaction of patients should not be neglected; this includes family relationships and support as well as peer influence. CONCLUSION: Study findings put forth issues and challenges faced by TB patients while receiving treatment and underscore areas where actions can be taken. This will contribute to informing the development and implementation of future TB control strategies that are responsive to TB patients' needs and concerns, to effectively address LTFU and ensure better treatment completion rates among TB patients in Malaysia.

A scoping review on the factors associated with the lost to follow-up (LTFU) amongst patients with chronic disease in ambulatory care of high-income countries (HIC).

BACKGROUND: Despite the importance of long term follow-up care for patients with chronic disease, many patients fail to adhere to their follow-ups, which increase their risk of further health complications. Therefore, the purpose of this scoping review was to find out the factors associated with lost to follow-up (LTFU) amongst patients with chronic disease in the ambulatory care setting of high-income countries (HICs) to gain insights for better quality of care. Understanding the definition of LTFU is imperative in informing patients, health professionals and researchers for clinical and research purposes. This review also provided an overview of the terms and definitions used to describe LTFU. METHODS: The following databases: CINAHL, EMBASE, Medline, PsycINFO and Web of Science were searched for studies investigating the factors associated to LTFU from the date of inception until 07 January 2022. RESULTS: Five thousand one hundred and seven records were obtained across the databases and 3,416 articles were screened after removing the duplicates. 25 articles met the inclusion criteria, of which 17 were cohort studies, five were cross-sectional studies and three were case-control studies. A total of 32 factors were found to be associated with LTFU and they were categorised into patient factors, clinical factors and healthcare provider factors. CONCLUSION: Overall, the factors associated with LTFU were generally inconsistent across studies. However, some factors such as financial factors (i.e., no insurance coverage) and low accessibility of care were consistently associated with LTFU for both mental and physical chronic conditions. The operational definitions of LTFU also varied greatly across studies. Given the mixed findings, future research using qualitative aproaches would be pivotal in understanding LTFU for specific chronic diseases and the development of targeted interventions. Additionally, there is a need to standardise the operational definition of LTFU for research as well as clinical practice purposes.

Retrieval of HCV patients lost to follow-up as a strategy for Hepatitis C Microelimination: results of a Brazilian multicentre study.

BACKGROUND: Several HCV patients in Brazil were lost to follow-up (LTFU) in the last two decades before achievement of sustained virological response (SVR). Strategies to recall those diagnosed but untreated patients have been used elsewhere with different success rates. AIM: To identify and retrieve LTFU patients in order to offer them the treatment with the current highly effective direct acting antiviral agents (DAAs). METHODS: Registries ofall HCV patients from three large reference centers in Brazil were retrospectively reviewed to identify those with no registry of SVR. Reasons for non-achievement of SVR were elicited in HCV-RNA + patients. All patients who were not treated or cured were contacted to offer the therapy with DAAs. RESULTS: 10,289 HCV patients (50% males, mean age 52 ± 11 years) were identified. Only 4,293 (41.7%) had been successfully treated previously. From the remaining 5,996 most were LTFU (59%), were not treated for other reasons (14.7%) or were non-responders (26.3%). After revision of the charts 3,559 were considered eligible to be retrieved. The callback success of phone calls was 18%, 13% to cellphone messages (SMS or WhatsApp) and 7% to regular mail. Five-hundred sixty patients had been already treatedor were on treatment and 234 were reported to be dead or transplanted. Finally, 201 had made an appointment and initiated antiviral treatment. CONCLUSION: Even considering the low callback rate, retrieval of LTFU patients was shown to be an important strategy forhepatitis C micro-elimination in Brazil.

Preventing lost-to-follow up diagnostic imaging in ambulatory care: evaluation of an electronic notification tool.

OBJECTIVE: Missed or cancelled imaging tests may be invisible to the ordering clinician and result in diagnostic delay. We developed an outpatient results notification tool (ORNT) to alert physicians of patients' missed radiology studies. DESIGN: Randomised controlled evaluation of a quality improvement intervention. SETTING: 23 primary care and subspecialty ambulatory clinics at an urban academic medical centre. PARTICIPANTS: 276 physicians randomised to intervention or usual care. MAIN OUTCOME MEASURE: 90-day test completion of missed imaging tests. RESULTS: We included 3675 radiology tests in our analysis: 1769 ordered in the intervention group and 1906 in the usual care group. A higher per cent of studies were completed for intervention compared with usual care groups in CT (20.7% vs 15.3%, p=0.06), general radiology (19.6% vs 12.0%, p=0.02) and, in aggregate, across all modalities (18.1% vs 16.1%, p=0.03). In the multivariable regression model adjusting for sex, age and insurance type and accounting for clustering with random effects at the level of the physician, the intervention group had a 36% greater odds of test completion than the usual care group (OR: 1.36 (1.097-1.682), p=0.005). In the Cox regression model, patients in the intervention group were 1.32 times more likely to complete their test in a timely fashion (HR: 1.32 (1.10-1.58), p=0.003). CONCLUSIONS: An electronic alert that notified the responsible clinician of a missed imaging test ordered in an ambulatory clinic reduced the number of incomplete tests at 90 days. Further study of the obstacles to completing recommended diagnostic testing may allow for the development of better tools to support busy clinicians and their patients and reduce the risk of diagnostic delays.

Factors associated with retention of mother-baby pairs in the elimination of mother-to-child transmission of HIV program in Kaberamaido district: A longitudinal analysis.

BACKGROUND: Retention along the elimination of Mother to Child Transmission (eMTCT) cascade in Uganda remains poor as only 62.7%-69.5% are followed up to 18months. The objective of this study was to determine the rates of retention of mother-baby pairs at two levels of the eMTCT cascade (12 and 18 months) and associated factors. METHODS: This was a longitudinal analysis of 368 mother-baby pairs who were enrolled into the eMTCT program in Kaberamaido district from January 2013 to December 2018. Data was extracted from early infant diagnosis (EID) and mothers' ART registers, entered into Microsoft Excel and then exported to Stata statistical software package version 14.0 for management and analysis. Descriptive statistics such as mean and frequencies were computed at univariate level. At the bivariate level, Cox proportional hazard regression was performed to assess the level of association between the primary outcome and each independent variable, while Cox proportional hazard regression model was built at multivariate level to determine the factors independently associated with retention of mother-baby pairs in the eMTCT program. RESULTS: Of the 368 mothers enrolled into the study, their average age was 29.7years (SD = 6.6). Nearly two-thirds of the mothers were married/cohabiting, (n = 232, 63.0%). The 368 mother baby pairs were observed for a total time of 6340 person months, with majority, 349 (94.8%, 95%CI = 92.0-96.7) still active in eMTCT care, while 19(5.2%, 95%CI = 3.3-8.0) were lost to follow up at 12months. At 18 months, 323 (87.8%, 95%CI = 84.0-90.8) were active in eMTCT program while 45(12.2%, 95 CI = 9.2-16.0) were lost to follow up. At bivariate level, marital status, health facility level of enrolment, mothers' ART treatment supporter, and mothers' ART enrolment time were significantly associated with survival/lost to follow up (LTFU) of mother-baby pairs along the eMTCT cascade. At multivariable level, the mothers' time of ART initiation was significantly associated with survival/lost to follow up (LTFU) of mother-baby pairs at along the eMTCT cascade, with mothers-baby pairs who were initiated during the antenatal/post-natal periods having higher hazards of LTFU compared to those who initiated ART before Antenatal period (before pregnancy), aHR = 4.37(95%CI, 1.62-11.76, P = 0.003). Mother-baby pairs who were enrolled into the eMTCT program after the implementation of HIV test and treat policy (year 2017 and 2018) had higher hazards of LTFU as compared to those enrolled before the implementation of test and treat policy in Uganda (year 2013-2016), aHR = 2.22(95% CI, 1.15-4.30, P = 0.017). All the other factors had no significant association with lost to follow up and cascade completion at multivariate level. CONCLUSION: There was high level of retention of mother-baby pairs in the eMTCT program in Kaberamaido at 12 months, but it was suboptimal at 18months. ART initiation during the antenatal and/or post-natal period was significantly associated with suboptimal retention of mother-baby pairs along the eMTCT cascade.

The effect of TB patient delay on loss to follow-up in Portugal.

BACKGROUND: Early identification of TB cases, followed by treatment to completion, are essential for controlling and preventing the disease. Previous studies have found some factors associated with both loss to follow-up (LTFU) and patient delay. We aim to build a causal model to investigate the association between TB patient delay and LTFU.METHODS: Pulmonary TB cases were identified using the national surveillance system in Portugal between 2008 and 2017. A directed acyclic graph was used to identify the minimal set of variables to adjust for when studying the association between delay (exposure) and LTFU (outcome). Crude and adjusted hazard were estimated using Cox regression.RESULTS: Nearly 4% of the patients did not follow up treatment. There was no association between patient delay and LTFU, even after adjustment with the minimal set of covariates. Factors associated with a higher risk of LTFU were being younger, being unemployed, living in urban areas, having HIV and the abuse of alcohol and drugs.CONCLUSION: Patient delay was not associated with LTFU, while social conditions were. Future research should investigate the underlying reasons why patients discontinue TB treatment and use these findings to develop targeted interventions that can support patients in completing their treatment regimen.

Analyze of factors and prognosis of eyes lost to follow-up in retinal vein occlusive disease patients receiving anti-vascular endothelial growth factor therapy.

BACKGROUND: Patients with macular edema (ME) secondary to retinal vein occlusion (RVO) who received at least one intravitreal injection of anti-vascular endothelial growth factor therapy (VEGF) and lost to follow-up (LTFU) for more than six months were analyzed to investigate the factors contributing to the LTFU and the prognosis. METHOD: This was a retrospective, single-center study to analyze the causes and prognosis of LTFU over six months in RVO-ME patients treated with intravitreal anti-VEGF injections at our institution from January 2019 to August 2022 and to collect patients' baseline characteristics along with the number of injections before LTFU, primary disease, best corrected visual acuity (BCVA) before LTFU and after return visit, central macular thickness (CMT), months before LTFU and after LTFU, reasons for LTFU, and complications, to analyze the factors affecting visual outcome at a return visit. RESULTS: This study included 125 patients with LTFU; 103 remained LTFU after six months, and 22 returned after LTFU. The common reason for LTFU was "no improvement in vision" (34.4%), followed by "transport inconvenience" (22.4%), 16 patients (12.8%) were unwilling to visit the clinic, 15 patients (12.0%) had already elected to seek treatment elsewhere, 12 patients (9.6%) were not seen in time due to the 2019-nCov epidemic, and 11 patients (8.8%) cannot do it due to financial reasons. The number of injections before LTFU was a risk factor for LTFU (P < 0.05). LogMAR at the initial visit (P < 0.001), CMT at the initial visit (P < 0.05), CMT before the LTFU (P < 0.001), and CMT after the return visit (P < 0.05) were influential factors for logMAR at the return visit. CONCLUSION: Most RVO-ME patients were LTFU after anti-VEGF therapy. Long-term LTFU is greatly detrimental to the visual quality of patients; thus, the management of RVO-ME patients in follow-up should be considered.

"Day or night, no matter what, I will go": Women's perspectives on challenges with follow-up care after cervical cancer screening in Iquitos, Peru: a qualitative study.

BACKGROUND: The study's objective was to explore the factors associated with loss to follow-up among women with abnormal cervical cancer screening results in Iquitos, Peru from women's perspectives. METHODS: In-depth interviews were conducted with 20 screen-positive women who were referred for follow-up care but for whom evidence of follow-up was not found. Interview transcripts were thematically analyzed inductively, and the codes were then categorized using the Health Care Access Barriers Model for presentation of results. RESULTS: All interviewed women were highly motivated to complete the continuum of care but faced numerous barriers along the way, including cognitive barriers such as a lack of knowledge about cervical cancer and poor communication from health professionals regarding the process, structural barriers such as challenges with scheduling appointments and unavailability of providers, and financial barriers including out-of-pocket payments and costs related to travel or missing days of work. With no information system tracking the continuum of care, we found fragmentation between primary and hospital-level care, and often, registration of women's follow-up care was missing altogether, preventing women from being able to receive proper care and providers from ensuring that women receive care and treatment as needed. CONCLUSIONS: The challenges elucidated demonstrate the complexity of implementing a successful cervical cancer prevention program and indicate a need for any such program to consider the perspectives of women to improve follow-up after a positive screening test.

Retrieval of patients with hepatitis C who were lost to follow-up in Southern Denmark.

BACKGROUND: The goal of the C-Free-South project is to eliminate hepatitis C (HCV) in the Region of Southern Denmark (1.2 million inhabitants). One target group consists of people with HCV who had received care but were lost to follow-up. The study aim was to evaluate program efficacy in locating these patients and getting them into care. METHODS: Patients were contacted if they were HCV-RNA positive and age 18+ years, registered in the clinical hepatitis database as of November 1, 2019, and had no scheduled HCV-related appointment. They were contacted at 2-month intervals by phone or letter. For patients who did not respond, we asked their general practitioner to refer them, if possible. RESULTS: We identified 69 (7%) patients in the database who were listed as untreated and not being followed up. We successfully contacted 54 (78%), and the remaining 15 (22%) did not respond to our contacts. To date, 45 (65%) had initiated treatment, one (1%) had rejected treatment, and eight (12%) did not show up to their appointments. Among those receiving treatment, 20 (44%) responded after the first contact, 18 (40%) after the second contact, and 7 (16%) after informing the general practitioner. CONCLUSION: An intensified and persistent effort made it possible to reach most HCV patients lost to follow-up. All new contact attempts increased the possibility that patients would receive treatment. Nevertheless, 22% of HCV patients lost to follow-up did not respond to repeated contact attempts.

Who is lost to follow-up in HIV care? Assessment of care retention over time and the impact of COVID-19. Longitudinal analysis of the PISCIS cohort.

INTRODUCTION: People living with HIV who are lost to follow-up have a greater risk of health deterioration, mortality, and community transmission. OBJECTIVE: Our aim was to analyse both how rates of loss to follow-up (LTFU) changed between 2006 and 2020 and how the COVID-19 pandemic affected these rates in the PISCIS cohort study of Catalonia and the Balearic Islands. METHODS: We analysed socio-demographic and clinical characteristics of LTFU yearly and with adjusted odds ratios to assess the impact of these determinants on LTFU in 2020 (the year of COVID-19). We used latent class analysis to categorize classes of LTFU based on their socio-demographic and clinical characteristics at each year. RESULTS: In total, 16.7% of the cohort were lost to follow-up at any time in the 15 years (n = 19 417). Of people living with HIV who were receiving follow-up, 81.5% were male and 19.5% were female; of those who were lost to follow-up, 79.6% and 20.4% were male and female, respectively (p < 0.001). Although rates of LTFU increased during COVID-19 (1.11% vs. 0.86%, p = 0.024), socio-demographic and clinical factors were similar. Eight classes of people living with HIV who were lost to follow-up were identified: six for men and two for women. Classes of men (n = 3) differed in terms of their country of birth, viral load (VL), and antiretroviral therapy (ART); classes of people who inject drugs (n = 2) differed in terms of VL, AIDS diagnosis, and ART. Changes in rates of LTFU included higher CD4 cell count and undetectable VL. CONCLUSIONS: The socio-demographic and clinical characteristics of people living with HIV changed over time. Although the circumstances of the COVID-19 pandemic increased the rates of LTFU, the characteristics of these people were similar. Epidemiological trends among people who were lost to follow-up can be used to prevent new losses of care and to reduce barriers to achieve Joint United Nations Programme on HIV/AIDS 95-95-95 targets.

Lost to Follow-Up among Tuberculosis Patients during the Public-Private Mix Era in Rural Area of Indonesia.

Background: Indonesia's national Tuberculosis (TB) strategy is public-private mix (PPM). The PPM aims to treat patients who have lost sight during TB treatment as these patients are TB carriers and at risk of transmitting TB. The purpose of this study was to identify predictive factors for loss to follow-up (LFTU) among TB patients receiving treatment when the PPM was at place in Indonesia. Methods: The design of this study was a retrospective cohort study. The data used in this study was sourced from the Tuberculosis Information System (SITB) of Semarang which was recorded routinely during 2020-2021. Univariate analysis, crosstabulation, and logistic regression were performed on 3434 TB patients meeting the minimum variables. Results: The participation of health facilities in reporting TB during the PPM era in Semarang reached 97.6% consisting of 37 primary healthcare center (100%), 8 public hospitals (100%), 19 private hospitals (90.5%), and a community-based pulmonary health center (100%). The regression analysis reveal that the predictive factors of LTFU-TB during the PPM are the year of diagnosis (AOR=1.541; p-value=<0.001; 95% CI=1.228-1.934), referral status (AOR=1.562, p-value=0.007; 95% CI=1.130-2160), healthcare and social security insurance ownership (AOR=1.638; p-value=<0.001; 95% CI=1.263-2.124), drugs source (AOR=4.667; p-value=0.035; 95% CI=1.117-19.489). Conclusions: The PPM strategy in dealing with LTFU patients should focus on TB patients without Healthcare and Social Security Insurance and who receive TB treatment rather than program drugs.
