Article Synopsis
  • - The study investigates transportation-related barriers that people living with HIV face in South Carolina, emphasizing the need to address these issues to enhance care and reduce health disparities in the region.
  • - Interviews with 20 individuals revealed challenges like unreliable and unsafe transportation, as well as stigma, which negatively impact their engagement in HIV care and overall health.
  • - Findings suggest that flexible clinic policies and support from friends and family can help overcome these transportation hurdles, highlighting the need for targeted interventions to improve access to HIV care.

Article Synopsis
  • The study assessed whether identifying people with HIV (PWH) at risk of falling out of care, along with automated outreach prompts, improved retention in care across 20 healthcare centers in the U.S.
  • Results indicated that 56% of PWH in care were flagged, and both the intervention and control groups had similar visit rates after being flagged, but intervention centers slightly outperformed controls.
  • The proportion of at-risk PWH achieving viral load suppression improved more significantly in intervention centers, suggesting potential benefits of integrating automated flags into existing care systems.

Economic strengthening interventions are needed to support HIV outcomes among persons living with HIV (PLWH). The Baton Rouge Positive Pathway Study (BRPPS), a mixed method implementation science study, was conducted to assess key RE-AIM components tied to the provision of conditional financial incentives among PLWH in Baton Rouge, Louisiana. Seven hundred and eighty-one (781) PLWH enrolled at four HIV clinic sites were included in the final analyses.

In 2020, the HIV prevention clinical trials, HPTN (HIV Prevention Trials Network) 083 and 084, reported that long-acting injectable cabotegravir (CAB-LA) for HIV prevention was statistically superior to daily oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) for pre-exposure prophylaxis (PrEP) in cisgender men and transgender women who have sex with men, and cisgender women. However, clinical efficacy does not translate to real-world effectiveness and clinical practice as evidenced by current global use of oral PrEP. There are ~626,000 users of PrEP, which is significantly below the 3 million goal set by UNAIDS for 2020.

Objectives: The objective of our study was to use a diverse sample of medical interventions to assess empirically whether first trials rendered substantially different treatment effect estimates than reliable, high-quality bodies of evidence.

Study Design And Setting: We used a meta-epidemiologic study design using 100 randomly selected bodies of evidence from Cochrane reports that had been graded as high quality of evidence. To determine the concordance of effect estimates between first and subsequent trials, we applied both quantitative and qualitative approaches.

Objectives: We sought to determine whether producers or users of systematic reviews using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach or a close variation give the same meanings to terms intended to convey uncertainty about treatment effects when interpreting grades for the quality or strength of evidence.

Study Design And Setting: Following exploratory interviews with stakeholders and user testing, we conducted an international Web-based survey among producers and users of systematic reviews. For each quality grade (high, moderate, low, very low/insufficient), we asked participants to assign a minimum likelihood that treatment effects will not change substantially as new studies emerge.

Introduction: This article, derived from a Technical Brief prepared for the Agency for Healthcare Research and Quality, presents an overview on current models of care for survivors of adult-onset cancer who have completed active treatment.

Methods: This article integrates reviewed literature on background, context, research gaps, and future research directions for survivorship care models. We also conducted a systematic literature review of current evidence from studies of survivorship care models.
