RESUMEN

Loss to follow-up (LTFU) from Option B plus, a lifelong antiretroviral therapy (ART) for pregnant women living with human immunodeficiency virus (HIV), irrespective of their clinical stage and CD4 count, threatens the elimination of vertical transmission of the virus from mothers to their infants. However, evidence on reasons for LTFU and resumption after LTFU to Option B plus care among women has been limited in Ethiopia. Therefore, this study explored why women were LTFU from the service and what made them resume or refuse resumption after LTFU in Ethiopia. An exploratory, descriptive qualitative study using 46 in-depth interviews was employed among purposely selected women who were lost from Option B plus care or resumed care after LTFU, health care providers, and mother support group (MSG) members working in the prevention of mother-to-child transmission unit. A thematic analysis using an inductive approach was used to analyze the data and build subthemes and themes. Open Code Version 4.03 software assists in data management, from open coding to developing themes and sub-themes. We found that low socioeconomic status, poor relationship with husband and/or family, lack of support from partners, family members, or government, HIV-related stigma, and discrimination, lack of awareness on HIV treatment and perceived drug side effects, religious belief, shortage of drug supply, inadequate service access, and fear of confidentiality breach by healthcare workers were major reasons for LTFU. Healthcare workers' dedication to tracing lost women, partner encouragement, and feeling sick prompted women to resume care after LTFU. This study highlighted financial burdens, partner violence, and societal and health service-related factors discouraged compliance to retention among women in Option B plus care in Ethiopia. Women's empowerment and partner engagement were of vital importance to retain them in care and eliminate vertical transmission of the virus among infants born to HIV-positive women.

RESUMEN

OBJECTIVES: Management of Hepatitis B virus (HBV)-infected patients, whether they are receiving treatment or not, necessitates long-term follow-up. This study evaluated the rate of lost to follow-up (LTFU) among HBV-infected patients and the feasibility of a callback strategy to re-engage these patients in HBV care. PATIENTS AND METHODS: We conducted a retrospective study involving HBV-infected patients attending the outpatient clinic at Cayenne Hospital, French Guiana. LTFU was defined as patients who had not attended the clinic for more than 18 months. A callback strategy was implemented to re-engage LTFU patients in HBV care. RESULTS: Between 1st January 2015 and 31st December 2018, 203 HBV-infected patients were referred to the outpatient clinic; 95/203 (46.8 %) were LTFU, resulting in a crude LTFU rate of 2.6 (95 % CI, 2.1-3.2) per 100 person-years. At baseline, patients aged 30-40 years (aOR, 0.48; 95 %CI, 0.24-0.95) and those who initiated treatment (aOR, 0.26; 95 %CI, 0.10-0.60) were less likely to be LTFU. Through application of the callback strategy, 55/95 (58 %) patients were successfully contacted, and 46/55 (84 %) attended the outpatient clinic for a liver assessment. The EASL criteria for treatment eligibility were met by 3/46 (4 %) patients. Compared to non-LTFU patients, LTFU patients were more likely to be in informal employment (p = 0.03) and to be receiving state medical assistance (p < 0.01), and had lower levels of knowledge about their condition (p < 0.01). CONCLUSIONS: The callback strategy to re-engage LTFU patients in HBV care is feasible and effectively identifies those eligible for antiviral therapy.

RESUMEN

INTRODUCTION: While there is an interest in defining longitudinal change in people with chronic illness like Parkinson's disease (PD), statistical analysis of longitudinal data is not straightforward for clinical researchers. Here, we aim to demonstrate how the choice of statistical method may influence research outcomes, (e.g., progression in apathy), specifically the size of longitudinal effect estimates, in a cohort. METHODS: In this retrospective longitudinal analysis of 802 people with typical Parkinson's disease in the Luxembourg Parkinson's study, we compared the mean apathy scores at visit 1 and visit 8 by means of the paired two-sided t-test. Additionally, we analysed the relationship between the visit numbers and the apathy score using linear regression and longitudinal two-level mixed effects models. RESULTS: Mixed effects models were the only method able to detect progression of apathy over time. While the effects estimated for the group comparison and the linear regression were smaller with high p-values (+ 1.016/ 7 years, p = 0.107, -0.056/ 7 years, p = 0.897, respectively), effect estimates for the mixed effects models were positive with a very small p-value, indicating a significant increase in apathy symptoms by + 2.345/ 7 years (p < 0.001). CONCLUSION: The inappropriate use of paired t-tests and linear regression to analyse longitudinal data can lead to underpowered analyses and an underestimation of longitudinal change. While mixed effects models are not without limitations and need to be altered to model the time sequence between the exposure and the outcome, they are worth considering for longitudinal data analyses. In case this is not possible, limitations of the analytical approach need to be discussed and taken into account in the interpretation.

RESUMEN

After bariatric surgery lifelong follow-up is recommended. Evidence of the consequences and reasons for being lost to follow-up (LTFU) is sparse. In this prospective study follow-up data of all patients who underwent bariatric surgery between 2008 and 2017 at a certified obesity centre were investigated. LTFU patients were evaluated through a structured telephone interview. Overall, 573 patients (female/male 70.9%/29.1%), aged 44.1 ± 11.2 years, preoperative BMI 52.1 ± 8.4 kg/m2 underwent bariatric surgery. Out of these, 33.2% had type 2 diabetes mellitus and 74.4% had arterial hypertension. A total of 290 patients were LTFU, of those 82.1% could be reached. Baseline characteristics of patients in follow-up (IFU) and LTFU were comparable, but men were more often LTFU (p = 0.01). Reported postoperative total weight loss (%TWL) and improvements of comorbidities were comparable, but %TWL was higher in patients remaining in follow-up for at least 2 years (p = 0.013). Travel issues were mentioned as the main reason for being LTFU. A percentage of 77.6% of patients reported to regularly supplement micronutrients, while 71.0% stated regular monitoring of their micronutrient status, mostly by primary care physicians. Despite comparable reported outcomes of LTFU to IFU patients, the duration of the in-centre follow-up period affected %TWL. There is a lack of sufficient supplementation and monitoring of micronutrients in a considerable number of LTFU patients.

RESUMEN

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.

RESUMEN

BACKGROUND: People lost to follow-up (LTFU) from HIV care have an increased risk of worse health. The objective of this study is to create and validate a risk score to predict LTFU among PLWH in Catalonia and the Balearic Islands. METHODS: 6661 PLWH were included. LTFU were those without contact with HIV care for 12 months or more. Logistic regression models were used to assess the role of independent factors on LTFU. The validation included a 10-fold iteration to predict the performance of the regression model and the Area under the ROC Curve (AUC). Regression coefficients were rounded and summed to construct the score. RESULTS: Determinants of LTFU included being younger than 34 years (OR: 1.80, CI, 1.44-2.23), not having been born in Spain (OR: 1.32, 1.11-1.58), men who inject drugs (OR: 2.10, 1.38-3.19), having a detectable viral load (OR: 3.14, 2.47-3.99), and ≤2.5 years since HIV diagnosis (OR: 3.84, 3.10-4.75). The validation of determinants resulted in a mean AUC of 0.69 and the risk-score revealed that 28.8% had a medium and 3.4% a high risk of LTFU respectively. CONCLUSIONS: Findings can be used to prevent LTFU in HIV care.

RESUMEN

Background: The effect of dolutegravir (DTG)-based regimens on reducing attrition from care among women enrolled in the prevention of mother-to-child transmission (PMTCT) care program is unknown. Therefore, this study aimed to compare the incidence of attrition among women exposed to DTG-based with those exposed to efavirenz (EFV)-based first-line antiretroviral therapy (ART) in Ethiopia. Methods: An uncontrolled before-and-after study was conducted involving 932 women (with 466 on EFV-based and 466 on DTG-based regimens) who were enrolled in the PMTCT care program from September 2015 to February 2023. The outcome variable was attrition (i.e., maternal death or loss to follow-up before their infants' final HIV status was determined). A Kaplan-Meier estimator was employed to estimate the probability of attrition. The Cox proportional hazards regression model was fitted to identify predictor variables. The adjusted hazard ratio (aHR) with the corresponding 95% confidence interval (CI) was calculated to examine the risk difference in the comparison groups. Results: The cumulative incidence of attrition among women was 5.2% (3.0% for those placed in the DTG-based regimen arm and 7.3% for those placed in the EFV-based regimen arm). Women on DTG-based regimens had a 57% (aHR: 0.43; 95% CI: 0.23-0.80) lower risk of attrition from care compared to those on EFV-based regimens. Women who delivered their infants at home (aHR: 2.35; 95% CI: 1.14-4.85), had poor/fair adherence (aHR: 3.23; 95% CI: 1.62-6.45), had unsuppressed/unknown viral load status (aHR: 2.61; 95% CI: 1.42-4.79), and did not disclose their status to partners (aHR: 2.56; 95% CI: 1.34-4.92) had a higher risk of attrition from PMTCT care compared to their counterparts. Conclusion: The cumulative incidence of attrition among women receiving PMTCT care is optimal. In addition, the risk of attrition among women receiving DTG-based regimens is lower than that among women receiving EFV-based regimens. Thus, DTG-based first-line ART regimen supplementation should be sustained to achieve a national retention target of 95% and above.

RESUMEN

BACKGROUND: The term "non-utilised appointments" emerged in 2019 but lacks a clear definition. We focus on multiple non-utilised appointments due to recent advances in understanding 'missingness' in UK healthcare. Studies on missed appointments show conflicting results regarding interventions like text messaging due to oversight of occasional versus repeated missed appointments. Understanding patient and healthcare-related factors in multiple non-utilised appointments is crucial for improving interventions and patient engagement. AIM: To identify factors influencing multiple non-utilised appointments from patients' and healthcare providers' perspectives. DESIGN & SETTING: A systematic review of qualitative research identifying factors that influence multiple non-utilised appointments across diverse global health care settings. METHOD: The review employed a qualitative systematic approach, encompassing diverse papers from multiple databases, irrespective of patient or healthcare provider age, location, or setting. Data analysis followed Thomas and Harden's thematic synthesis method. Themes are presented in alignment with both the health service and patient perspective aspects of the Levesque access model. RESULTS: Ten thousand and eighty-six records were retrieved. Five studies met the inclusion criteria and were analysed. Six key themes influenced appointment utilisation. Healthcare system determinants highlighted provider-patient relationship and professionalism, and healthcare organisation factors role in appointments utilisation. Patient experience and decision-making explored personal factors. Additionally, communication, support, and engagement delved into challenges with communication and language, family and social support, and socio-familial barriers to appointment utilisation. Health and well-being factors encompassed medical conditions, mental and emotional factors, and psychosocial determinants affecting appointment utilisation. Moreover, financial constraints and socioeconomic factors were identified as significant contributors. Lastly, healthcare access and barriers addressed transportation challenges, accessibility issues, and geographical barriers impacting healthcare access. CONCLUSION: The analysis reveals complex factors influencing multiple non-utilised appointments. Strong provider-patient relationships improve care accessibility. Flexible scheduling and patient-centred approaches are pivotal, alongside addressing workplace discrimination. Tailored healthcare services and overcoming geographical barriers are essential. Ensuring safety, accessibility, and communication, while supporting vulnerable groups and mental health needs, are necessary. Equitable access to services and alternative transportation solutions are essential for comprehensive healthcare delivery. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42023429465.

RESUMEN

Disengagement from care among people with HIV (PWH) and hepatitis C (HCV) increases the risks of adverse health outcomes and poses significant barriers to achieving global HIV and HCV elimination goals. In accordance with the Joanna Briggs Institute framework, a scoping review was conducted to synthesize and highlight existing gaps in the literature on (dis)engagement in care among PWH and HCV. We searched for original studies on (dis)engagement in care among PWH and HCV in high-income countries using eight electronic databases from inception to May 2023. Our search yielded 4462 non-duplicated records, which were scoped to 27 studies. Definitions of (dis)engagement in care were diverse, with considerable heterogeneity in how retention was operationalized and temporally measured. Studies identified predictors of (dis)engagement to be related to drug and substance use (n = 5 articles), clinical factors (n = 5), social and welfare (n = 4), and demographic characteristics (n = 2). When engagement in care was treated as an exposure, it was associated with HCV treatment initiation (n = 3), achieving sustained virological response (n = 2), and maintaining HIV viral suppression (n = 1). Interventions to improve care engagement among PWH and HCV were limited to five studies using cash incentives (n = 1) and individual case management (n = 4). (Dis)engagement in care is a dynamic process influenced by shifting priorities that may 'tip the balance' towards or away from regularly interacting with healthcare professionals. However, inconsistent definitions render cross-study comparisons and meta-analyses virtually impossible. Further research needs to establish a standardized definition to identify patients at high risk of disengagement and develop interventions that leverage the nested HIV/HCV care cascades to retain and recover patients lost from care.

RESUMEN

Background: The Methadone Maintenance Treatment (MMT) program has been proven to be beneficial in reducing illicit opioid use, increasing access to and retention of HIV treatment and other therapies, and reducing HIV transmission, and other drug-related morbidities and mortalities. However, determinants of treatment retention and outcomes for opioid-dependent persons accessing MMT in Kenya are limited. We sought to identify factors contributing to poor treatment outcomes among opioid-dependent persons enrolled in the Mombasa MMT program, between 2017 and 2019. Method: We conducted a retrospective records review for opioid-dependent persons receiving Methadone treatment in the Kisauni MAT clinic enrolled during 2017-2019. We defined poor clinical or health-related treatment outcome as any client Lost-To-Follow-Up (LTFU), turned HIV or Viral hepatitis positive, and/or missed two or more antiretroviral therapy (ART) appointments intake during MMT. Variables abstracted from clinical and pharmacological MMT service delivery tools included socio-demographic characteristics, clinical history, risk factors, and MMT outcomes. Data were analyzed using Epi Info7. We calculated Prevalence Odds Ratios (POR) and 95% Confidence Intervals (CI) to identify factors associated with adverse health outcomes. Results: Of the total 443 eligible records, the mean age was 37 years (SD ± 7.2) and males comprised 90.7%. The majority of females clients, 79.1% (34/43), were aged ≤35 years, 7.0% (3/43) had no education, 32.6% (14/43) were employed, 39.5% (17/43) were HIV positive and 18.6% (8/43) were HCV-positive. Overall, adverse treatment outcomes were at 27.5% (122/443), namely: LTFU at 22.8% (101/443), new HIV cases at 1.0% (4/391), HCV at 1.2% (5/405), and Hepatitis B Virus (HBV) at 1.2% (5/411), and 1.1% (5/443) died. Of HIV-infected clients linked to Comprehensive Care Clinic (CCC), 3.6% (2/56) defaulted from ART, and 25% (2/8) had detectable Viral Load of those retested. Lack of formal education (POR: 2.7, 95% CI: 1.3-5.7), unemployment (POR: 2.4, 95% CI: 1.4-4.0), and being a Non-Injector (POR: 1.7, 95% CI: 1.0-2.9) were negatively associated with treatment retention. Conclusion: Females were younger, and more educated with higher HIV and HCV prevalence. Being a Non-injector, unemployment, and lack of formal education may increase the likelihood of poor treatment outcomes among MMT clients. Closer monitoring of MMT clients with these characteristics is recommended with the integration of CCC into MMT services.

RESUMEN

INTRODUCTION: Previous literature suggests socioeconomic status and racial disparities impact management decisions for patients with small renal masses. We aim to build upon these findings and examine how these modalities impact patient adherence to their management plan. METHODS: This retrospective study analyzed our Kidney Tumor Program database (n = 1476) containing patients from 2000 to 2020. Socioeconomic status was estimated using 2 modalities: Area Deprivation Index and household income. Patients were then evaluated for differences in adherence, nonadherence, and loss to follow-up. Adherent patients completed all recommended appointments within 6 months of their initial follow-up. Nonadherent patients did not complete all recommended appointments within 6 months of their originally scheduled follow-up but eventually did. Patients lost to follow-up were recommended to follow up but never did. RESULTS: Patient adherence was not significantly different across sex or primary treatment method but differed with respect to race/ethnicity. Black patients were significantly more likely to be nonadherent (P = .021) and lost to follow-up (P = .008). After adjusting for race/ethnicity, Area Deprivation Index and income bracket were significantly associated with adherence and loss to follow-up. Patients with a high socioeconomic status had significantly higher rates of adherence (ADI, quartile [Q] 1 vs Q4, P = .038; income, >$120,000 vs $30,000-$59,999, P < .003) and decreased loss to follow-up (ADI, Q1 vs Q4, P = .03; income, >$120,000 vs $30,000-$59,999, P = .002). CONCLUSIONS: Our results demonstrate that Black race and low socioeconomic status are associated with decreased adherence and increased loss to follow-up. Possible strategies to target these disparities include financial assistance programming, social determinants of health screening, and nurse navigator programs.

RESUMEN

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.

RESUMEN

Purpose: A high rate of lost to follow-up (LTFU) in patients with phenylketonuria (PKU) represents a main challenge. In this study, we investigated potential risk factors for becoming LTFU related to adolescence as a critical period of life. Methods: We retrospectively analyzed longitudinal data collected from 1993 to 2019 of patients diagnosed with classic PKU that were followed at our center during adolescence (14-18 y) and at least once in adulthood (>18 y). Patients who interrupted their contact with our center after the 18th birthday for at least 2 years were classified as LTFU. We performed a multivariate regression analysis to investigate following potential risk factors for becoming LTFU in adult life: sex, dietary compliance during adolescence assessed through the mean of the annual medians of phenylalanine plasma values, average number of contacts with the center during adolescence and age at first visit after the 18th birthday. Results: 93 patients (52 males, 41 females) were included in the study. 58% became LTFU during adulthood. The mean age at the last visit before becoming LTFU was 26.2 ± 5.1 years. In the multivariate Cox regression analysis we found that poor dietary compliance during adolescence was significantly associated with a higher risk of becoming LTFU during adulthood (p-value = 0.028). Discussion: Adult patients who displayed poor treatment adherence during adolescence should be identified and carefully monitored to prevent loss of contact.

RESUMEN

Background: The cascade of care, commonly used to assess HIV and hepatitis C (HCV) health service delivery, has limitations in capturing the complexity of individuals' engagement patterns. This study examines the dynamic nature of engagement and mortality trajectories among people with HIV and HCV. Methods: We used data from the Canadian HIV-HCV Co-Infection Cohort, which prospectively follows 2098 participants from 18 centers biannually. Markov multistate models were used to evaluate sociodemographic and clinical factors associated with transitioning between the following states: (1) lost-to-follow-up (LTFU), defined as no visit for 18 months; (2) reengaged (reentry into cohort after being LTFU); (3) withdrawn from the study (ie, moved); (4) death; otherwise remained (5) engaged-in-care. Results: A total of 1809 participants met the eligibility criteria and contributed 12 591 person-years from 2003 to 2022. LTFU was common, with 46% experiencing at least 1 episode, of whom only 57% reengaged. One in 5 (n = 383) participants died during the study. Participants who transitioned to LTFU were twice as likely to die as those who were consistently engaged. Factors associated with transitioning to LTFU included detectable HCV RNA (adjusted hazards ratio [aHR], 1.37; 95% confidence interval [CI], 1.13-1.67), evidence of HCV treatment but no sustained virologic response result (aHR, 1.99; 95% CI, 1.56-2.53), and recent incarceration (aHR, 1.94; 95% CI, 1.58-2.40). Being Indigenous was a significant predictor of death across all engagement trajectories. Interpretation: Disengagement from clinical care was common and resulted in higher death rates. People LTFU were more likely to require HCV treatment highlighting a priority population for elimination strategies.

RESUMEN

BACKGROUND: Maintaining people living with HIV (PLWHIV) in clinical care is a global priority. In the Metro Detroit area of Michigan, approximately 30% of PLWHIV are out of care. To re-engage lost-to-follow-up patients, Wayne Health Infectious Disease clinic launched an innovative Homecare program in 2017. In addition to home healthcare delivery, the program included links to community resources and quarterly community meetings. We aimed to evaluate Homecare's impact on participants' ability to stay engaged in HIV care and reach viral suppression. We included data from PLWHIV and their healthcare workers. METHODS: We used a convergent mixed-methods design, including first year program record review, semi-structured interviews, and a validated Likert scale questionnaire rating illness perception before and after Homecare. Interview data were collected from 15 PLWHIV in Metro Detroit and two healthcare workers responsible for program delivery. Semi-structured interviews focused on obstacles to clinic-based care, support networks, and illness perceptions. Interview data were transcribed and analyzed using a thematic approach. A fully coded analysis was used to create a conceptual framework of factors contributing to Homecare's success. Means in eight categories of the Brief Illness Perception (IPQ) were compared using paired T-tests. RESULTS: In the first year of Homecare, 28 of 34 participants (82%) became virally suppressed at least once. The program offered (1) social support and stigma reduction through strong relationships with healthcare workers, (2) removal of physical and resource barriers such as transportation, and (3) positive changes in illness perceptions. PLWHIV worked towards functional coping strategies, including improvements in emotional regulation, acceptance of their diagnosis, and more positive perspectives of control. Brief-IPQ showed significant changes in six domains before and after Homecare. CONCLUSION: Homecare offers an innovative system for successfully re-engaging and maintaining lost-to-follow-up PLWHIV in care. These findings have implications for HIV control efforts and could inform the development of future programs for difficult to reach populations.

RESUMEN

BACKGROUND: Gaps in care (GIC) are common for patients with congenital heart disease (CHD) and can lead to worsening clinical status, unplanned hospitalization, and mortality. Understanding of how social determinants of health (SDOH) contribute to GIC in CHD is incomplete. We hypothesize that SDOH, including Child Opportunity Index (COI), are associated with GIC in patients with significant CHD. METHODS AND RESULTS: A total of 8554 patients followed at a regional specialty pediatric hospital with moderate to severe CHD seen in cardiology clinic between January 2013 and December 2015 were retrospectively reviewed. SDOH factors including race, ethnicity, language, and COI calculated based on home address and zip code were analyzed. GIC of >3.25 years were identified in 32% (2709) of patients. GIC were associated with ages 14 to 29 years (P<0.001), Black race or Hispanic ethnicity (P<0.001), living ≥150 miles from the hospital (P=0.017), public health insurance (P<0.001), a maternal education level of high school or less (P<0.001), and a low COI (P<0.001). Multivariable analysis showed that GIC were associated with age ≥14 years, Black race or Hispanic ethnicity, documenting <3 caregivers as contacts, mother's education level being high school or less, a very low/low COI, and insurance status (C statistic 0.66). CONCLUSIONS: One-third of patients followed in a regional referral center with significant CHD experienced a substantial GIC (>3.25 years). Several SDOH, including a low COI, were associated with GIC. Hospitals should adopt formal GIC improvement programs focusing on SDOH to improve continuity of care and ultimately overall outcomes for patients with CHD.

RESUMEN

BACKGROUND/PURPOSE: Pediatric Hodgkin lymphoma (HL) survivors have an increased risk of late effects following treatment. Barriers at the patient, provider, and payor level adversely affect adherence to long-term follow-up. METHODS: We conducted a retrospective chart review of HL survivors diagnosed from 1999 to 2014 at Texas Children's Hospital. HL survivors were considered lost to follow-up if there were no documented visits to Texas Children's Cancer Center Long-Term Survivor (LTS) clinic for 2 or more years after their last LTS clinic visit. Univariate and multivariable logistic regression analyses were conducted to explore factors contributing to loss to follow-up. Reasons for not attending subsequent LTS visits were assessed by phone interviews in a subset of lost to follow-up patients. RESULTS: There were 120 HL survivors who had at least one LTS clinic visit in this timeframe; 64 (53%) were classified as lost to follow-up, and of these, 23 (36%) were interviewed. Eleven (47%) indicated that the reason for failure to follow-up was lack of or inadequate insurance, and seven (30%) stated they were unaware of the importance of continued follow-up. Loss to follow-up was associated with lack of insurance, earlier diagnosis, and lack of comorbidities in univariate analyses. Only earlier year of diagnosis (odds ratio [OR] 0.84, 95% confidence interval [CI]: 0.7-0.9, p = .01) and lack of insurance (OR 22.2, 95% CI: 4-123, p < .001) were associated with loss to follow-up in multivariable analyses. CONCLUSIONS: Insurance status and awareness of the need for long-term follow-up care are key factors associated with loss to follow-up in survivors of HL. Targeted education and low-cost options for survivorship care are potential strategies for improving adherence to long-term follow-up care in HL survivors.

RESUMEN

BACKGROUND: HIV services in Tanzania are facility-based but facilities are often overcrowded. Differentiated care models (DCM) have been introduced into the National Guidelines. We piloted a Community Health Worker (CHW)-led HIV treatment club model (CHW-DCM) in an urban region, and assessed its effectiveness in comparison to the standard of care (SoC, facility-based model), in terms of stability in care, loss to follow-up (LTFU) and treatment adherence. METHODS: In two clinics in the Shinyanga region, clients established on ART (defined as stable clients by national guidelines as on first-line ART >6 months, undetectable viral load, no opportunistic infections or pregnancy, and good adherence) were offered CHW-DCM. This prospective cohort study included all stable clients who enrolled in CHW-DCM between July 2018 and March 2020 (CHW-DCM) and compared them to stable clients who remained in SoC during that period. Multivariable Cox regression models were used to analyse factors associated with continued stability in care and the risk of LTFU during 18 months of follow-up; treatment adherence was assessed by pill count and compared using Chi-square tests. RESULTS: Of 2472 stable clients, 24.5% received CHW-DCM and 75.5% SoC. CHW-DCM clients were slightly older (mean 42.8 vs. 37.9 years) and more likely to be female (36.2% vs. 32.2%). Treatment adherence was better among CHW-DCM than SoC: 96.6% versus 91.9% and 98.5% versus 92.2%, respectively (both p = 0.001). SoC clients were more likely to not remain stable over time than CHW-DCM (adjusted Hazard ratio [AHR] = 2.68; 95% CI: 1.86-3.90). There was no difference in LTFU (adjusted hazard ratio [AHR] = 1.54; 95%CI: 0.82-2.93). CONCLUSION: Clients attending CHW-DCM demonstrated better stability in care and treatment adherence than SoC, and the risk of LTFU was not increased. These findings demonstrate the potential of CHW in delivering community-based HIV services in the local Tanzanian context. These results could be used to extend this CHW-DCM model to similar settings.

RESUMEN

BACKGROUND: The treatment success rate for tuberculosis (TB) has stagnated at 80-81% in South Korea, indicating unsatisfactory outcomes. Enhancing treatment success rate necessitates the development of individualized treatment approaches for each patient. This study aimed to identify the risk factors associated with unfavorable treatment outcomes to facilitate tailored TB care. METHODS: We retrospectively analyzed the data of patients with active TB between January 2019 and December 2020 at a single tertiary referral center. We classified unfavorable treatment outcomes according to the 2021 World Health Organization guidelines as follows: "lost to follow-up" (LTFU), "not evaluated" (NE), "death," and "treatment failure" (TF). Moreover, we analyzed risk factors for each unfavorable outcome using Cox proportional hazard regression analysis. RESULTS: A total of 659 patients (median age 62 years; male 54.3%) were included in the study. The total unfavorable outcomes were 28.1%: 4.6% LTFU, 9.6% NE, 9.1% deaths, and 4.9% TF. Multivariate analysis showed that a culture-confirmed diagnosis of TB was associated with a lower risk of LTFU (adjusted hazard ratio [aHR], 0.25; 95% confidence interval [CI], 0.10-0.63), whereas the occurrence of adverse drug reactions (ADRs) significantly increased the risk of LTFU (aHR, 6.63; 95% CI, 2.63-16.69). Patients living far from the hospital (aHR, 4.47; 95% CI, 2.50-7.97) and those with chronic kidney disease (aHR, 3.21; 95% CI, 1.33-7.75) were at higher risk of being transferred out to other health institutions (NE). Higher mortality was associated with older age (aHR, 1.06; 95% CI, 1.04-1.09) and comorbidities. The ADRs that occurred during TB treatment were a risk factor for TF (aHR, 6.88; 95% CI, 2.24-21.13). CONCLUSION: Unfavorable outcomes of patients with TB were substantial at a tertiary referral center, and the risk factors for each unfavorable outcome varied. To improve treatment outcomes, close monitoring and the provision of tailored care for patients with TB are necessary.
