Direct acting antivirals (DAAs) have increased cure rates for hepatitis C virus (HCV) infection; however, there are several obstacles to the uptake of DAAs in populations where substance use contributes to HCV risk. This synthesis aimed to identify the patient and provider perceived barriers and facilitators to DAA treatment initiation in key patient subgroups-people who inject drugs (PWID), men who have sex with men (MSM), and Indigenous people. We systematically searched seven databases and conducted a gray literature search for studies that qualitatively explored patient and provider perceived barriers and facilitators to DAA treatment in our populations of interest. Selected studies were published after 2013 when second generation DAAs became available. The titles, abstracts, and subsequently full texts were screened by two independent reviewers and critically appraised. Barriers and facilitators to DAA treatment uptake were then extracted and thematically synthesized. 2144 titles and abstracts were identified and screened; 29 full texts were subsequently reviewed. Twelve qualitative studies were finally included. Among providers, perceived barriers to DAA treatment uptake included lack of resources and lack of provider knowledge on HCV while facilitators to treatment provision included simplicity of DAA regimens and professional identity as a doctor to advocate for patients. Among patients, perceived barriers to treatment uptake included current drug use, concerns about side effects of DAAs, stigma, gaps in community care, competing social responsibilities and mental health issues while facilitators included having a trustworthy provider and access to multidisciplinary HCV care. Despite simplicity of DAAs, many structural barriers to optimal HCV care continue to be experienced by patients and providers. In highlighting nuanced patient and provider perceived barriers and facilitators, this review underscores the need to involve participatory methods in the design and evaluation of interventions to best improve access to care.

Background: The COVID-19 pandemic has acted as a catalyst for the development and adoption of a broad range of remote monitoring technologies (RMTs) in health care delivery. It is important to demonstrate how these technologies were implemented during the early stages of this pandemic to identify their application and barriers to adoption, particularly among vulnerable populations. Objective: The purpose of this knowledge synthesis was to present the range of RMTs used in delivering care to patients with COVID-19 and to identify perceived benefits of and barriers to their use. The review placed a special emphasis on health equity considerations. Methods: A rapid review of published research was conducted using Embase, MEDLINE, and QxMD for records published from the inception of COVID-19 (December 2019) to July 6, 2020. Synthesis involved content analysis of reported benefits of and barriers to the use of RMTs when delivering health care to patients with COVID-19, in addition to health equity considerations. Results: Of 491 records identified, 48 publications that described 35 distinct RMTs were included in this review. RMTs included use of existing technologies (eg, videoconferencing) and development of new ones that have COVID-19–specific applications. Content analysis of perceived benefits generated 34 distinct codes describing advantages of RMTs, mapped to 10 themes overall. Further, 52 distinct codes describing barriers to use of RMTs were mapped to 18 themes. Prominent themes associated with perceived benefits included a lower burden of care (eg, for hospitals, health care practitioners; 28 records), reduced infection risk (n=33), and support for vulnerable populations (n=14). Prominent themes reflecting barriers to use of RMTs included equity-related barriers (eg, affordability of technology for users, poor internet connectivity, poor health literacy; n=16), the need for quality “best practice” guidelines for use of RMTs in clinical care (n=12), and the need for additional resources to develop and support new technologies (n=11). Overall, 23 of 48 records commented on equity characteristics that stratify health opportunities and outcomes, including general characteristics that vary over time (eg, age, comorbidities; n=17), place of residence (n=11), and socioeconomic status (n=7). Conclusions: Results of this rapid review highlight the breadth of RMTs being used to monitor and inform treatment of COVID-19, the potential benefits of using these technologies, and existing barriers to their use. Results can be used to prioritize further efforts in the implementation of RMTs (eg, developing “best practice” guidelines for use of RMTs and generating strategies to improve equitable access for marginalized populations).

Background: Vaccine uptake rates have been historically low in correctional settings. To better understand vaccine hesitancy in these high-risk settings, we explored reasons for COVID-19 vaccine refusal among people in federal prisons. Methods: Three maximum security all-male federal prisons in British Columbia, Alberta, and Ontario (Canada) were chosen, representing prisons with the highest proportions of COVID-19 vaccine refusal. Using a qualitative descriptive design and purposive sampling, individual semi-structured interviews were conducted with incarcerated people who had previously refused at least one COVID-19 vaccine until data saturation was achieved. An inductive–deductive thematic analysis of audio-recorded interview transcripts was conducted using the Conceptual Model of Vaccine Hesitancy. Results: Between May 19-July 8, 2021, 14 participants were interviewed (median age: 30 years; n = 7 Indigenous, n = 4 visible minority, n = 3 White). Individual-, interpersonal-, and system-level factors were identified. Three were particularly relevant to the correctional setting: 1) Risk perception: participants perceived that they were at lower risk of COVID-19 due to restricted visits and interactions; 2) Health care services in prison: participants reported feeling “punished” and stigmatized due to strict COVID-19 restrictions, and failed to identify personal benefits of vaccination due to the lack of incentives; 3) Universal distrust: participants expressed distrust in prison employees, including health care providers. Interpretation: Reasons for vaccine refusal among people in prison are multifaceted. Educational interventions could seek to address COVID-19 risk misconceptions in prison settings. However, impact may be limited if trust is not fostered and if incentives are not considered in vaccine promotion.

Patient navigation increases linkage to hepatitis C virus (HCV) care following release from prison; however, little is known about the services patient navigators should provide to maximize linkage to care. We aimed to identify perceived barriers and facilitators to linkage to HCV care post-release, and to determine patient navigator services and characteristics best suited to address barriers to linkage to care among people released from prison. Ten semi-structured interviews were conducted with adult (age ≥18 years) men living with chronic HCV, released from the largest Quebec provincial prison, and linked to HCV care by a patient navigator. Interviews were guided by the Socio-Ecological Model (SEM) and aimed to explore the multi-level barriers and facilitators to linkage to HCV care post-release. Interviews were audio-recorded, transcribed, and analyzed using a deductive, thematic approach. The median age of participants was 54 years. Barriers to linkage to HCV care included competing priorities post-release (e.g., substance use, mental health issues, unstable housing), stigma (related to HCV, injection drug use, and incarceration), and lack of transportation. Facilitators included social support, established relationships with existing healthcare providers, prior cure with direct-acting antivirals, and HCV-related health literacy and knowledge. Perceived essential patient navigator services to enhance linkage included pre-release discharge appointments, housing assistance, and facilitated transportation to HCV appointments. Ensuring a consistent, non-judgemental, and empathetic patient navigator were considered important characteristics; lived experiences of incarceration and/or HCV were not felt to be essential for a patient navigator. Interventions that seek to improve linkage to HCV care for people following release from prison should address many levels (individual, interpersonal, and policy) of the SEM. While people experience several competing priorities post-release, having an empathetic and consistent patient navigator, regardless of their lived experiences of HCV and/or incarceration, may improve linkage to HCV care post-release.

Clinical teachers perform overlapping tasks in education and patient care. They are therefore expected to juggle many professional identities such as educator and clinician. Yet little is known about how clinical teachers negotiate their professional identities. The present research examined the lived experiences of clinical teachers as they manage and make sense of their professional identities in the context of a faculty development program. This study adopted interpretative phenomenological analysis, which is an idiographic and inductive methodological approach that enables an in-depth examination of how people conceptualize their personal and social worlds. In-depth semi-structured individual interviews were conducted with six purposively sampled Brazilian clinical teachers who were attending a faculty development program. Each participant’s lived experience was analyzed independently. Then, these individual analyses were compared against each other to identify convergence and divergence. Participants recognized one identity, which was labeled as embedding identity, containing other identities and roles. Participants integrated their professional identities in agreement with their personal identities, values, and beliefs, striving thus for identity consonance. Participants understood their craft as a relational process by which they wove themselves into their context and entangled their experience with that of others. They, however, diverged when recognizing who their peers were; whereas some named a single professional group (i.e., family physicians), others had a more comprehensive view and considered as peers healthcare professionals, students, and even patients. Finally, participants identified time constraints and lower prestige of family medicine as a medical discipline vis-à-vis other specialties as challenges posed by their contexts. Clinical teachers have multifaceted identities, to which they give a sense, manage, and integrate into their daily practice. Participants recognized an embedding identity and looked for common points between the identities it contained, which allowed them to meaningfully reconcile the different demands from their overlapping professional identities. Thus, this research introduces the notion of embedding identity as a strategy to make sense of many professional identities. Variability in the embedding identities depicted in this investigation suggests the fluid and contextualized character of professional identity development. How participants saw themselves also influenced how they behaved and interacted with others accordingly. Understanding clinical teacher identity development enriches current perspectives of what it is like to be one of these medical professionals. Faculty development programs ought to consider these perspectives to better support clinical teachers in meeting the overlapping demands in education and patient care.
