A longitudinal, HIV care continuum: 10-year restricted mean time in each care continuum stage after enrollment in care, by history of IDU.

ABSTRACT: We present a novel, patient-centric, longitudinal summary of patient progress through the HIV care continuum. Using this new approach, we compare person-time spent alive, in care, on antiretroviral therapy (ART), and virally suppressed among people who inject drugs (PWID) and those who do not (non-IDU).Prospective clinical observational cohort study.We followed ART-naive patients with detectable HIV viral loads who enrolled in the Johns Hopkins HIV Clinical Cohort from enrollment until the occurrence of several care continuum-related milestones, including ART initiation and viral suppression, and until several care continuum-related failures, including loss to clinic and death. We added and subtracted cumulative incidence curves to estimate the proportion of the cohort in each of seven continuum stages across the 10 years following enrollment in clinical care.PWID composed 32% of the study sample (n?=?1443). Over 10 years following enrollment in care, PWID and non-IDU spent only 23 and 37%, respectively, of person-time in care, on ART, and virally suppressed. PWID lost 8.9 more months of life compared with non-IDU and spent an additional 5.0 months on ART but not virally suppressed, and an additional 5.5 months in care but not on ART. There were not meaningful improvements in the 5-year restricted mean person-time differences comparing PWID to non-IDU across enrollment cohorts (2000-2003, 2004-2007, 2008-2014).Efforts to increase viral suppression among PWID should focus on increasing ART initiation and improving adherence to therapy.

Project description:BackgroundDespite high morbidity and mortality, patients with injection drug use associated infective endocarditis (IDU-IE) lack standardized care, and experience prolonged hospitalization and variable substance use disorder (SUD) management. Our study's objective was to elicit perspectives of health care workers (HCWs) who deliver care to this population by understanding their perceived patient, provider, and system-level resources and barriers.MethodsThis qualitative study included interviews of HCWs providing care to patients with IDU-IE from January 2017 to December 2019 at a single Midwest academic center. Based on electronic medical record queries to determine high and low rates of referral to SUD treatment, HCWs were selected using stratified random sampling followed by convenience sampling of non-physician HCWs and a patient. Study participants were recruited via email and verbal consent was obtained. The final sample included 11 hospitalists, 3 specialists (including 2 cardiovascular surgery providers), 3 case managers, 2 social workers, 1 nurse, and 1 patient. Qualitative semi-structured interviews explored challenges and resources related to caring for this population. Qualitative Data Analysis (QDA) Minor Lite was used for thematic data using an inductive approach.ResultsThree major thematic categories emerged relative to patient-level barriers (e.g., pain control, difficult patient interactions, social determinants of health), provider-level barriers (e.g., inequity, expectations for recovery, varying levels of hope, communication style, prescribing medication for SUD), and system-level barriers (e.g., repeat surgery, placement, resources for SUD and mental health). The need to address underlying SUD was a prominent theme.ConclusionPractical steps we can take to improve treatment for this population include training and coaching HCWs on a more person-centered approach to communication and transparent decision-making around pain management, surgery decisions, and expectations for SUD treatment.

Project description:BackgroundPeople who inject drugs (PWID) are at continued risk for HIV in the U.S., and experience disparities across the HIV care continuum compared to other high-risk groups. Estimates of the risk of HIV transmission at each stage of the care continuum may assist in identifying public health priorities for averting incident infections among PWID, in addition to transmissions to sexual partners of PWID.MethodsWe created an agent-based model simulating HIV transmission and the HIV care continuum for PWID in New York City (NYC) in 2012. To account for sexual transmission arising from PWID to non-PWID, the simulation included the entire adult NYC population. Using surveillance data and estimates from the National HIV Behavioral Surveillance system, we simulated a dynamic sexual and injecting network. We estimated the proportion of HIV transmission events attributable to PWID in the following categories, those: without an HIV diagnosis ('Undiagnosed'); diagnosed but not on antiretroviral therapy (ART) ('Diagnosed - not on ART'); those who initiated ART but were not virally suppressed ('Unsuppressed'); and, those who achieved viral suppression ('Suppressed').ResultsWe estimated HIV incidence among PWID to be 113 per 100,000 person-years in 2012, with an overall incidence rate for the entire adult NYC population of 33 per 100,000 person-years. Despite accounting for only 33% of the HIV-infected PWID population, the Undiagnosed were associated with 52.6% (95% simulation interval [95% SI]: 47.1-57.0%) of total transmission events. The Diagnosed - not on ART population contributed the second-largest proportion of HIV transmissions, with 36.6% (95% SI: 32.2-41.5%). The Unsuppressed population contributed 8.7% (95% SI: 5.6-11.8%), and Suppressed 2.1% (95% SI: 1.1-3.9%), relatively little of overall transmission.ConclusionsAmong PWID in NYC, more than half (53%) of transmissions were from those who were unaware of their infection status and more than 36% were due to PWID who knew their status, but were not on treatment. Our results indicate the importance of early diagnosis and interventions to engage diagnosed PWID on treatment to further suppress population-level HIV transmission. Future HIV prevention research should focus on the elimination of identified and potential barriers to the testing, diagnosis, and retention of PWID on HIV treatment.
