BACKGROUND: The clinical burden of Long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and other post-infectious fatiguing illnesses (PIFI) is increasing. There is a critical need to advance understanding of the effectiveness and sustainability of innovative approaches to clinical care of patients having these conditions. METHODS: We aim to assess the effectiveness of a Long COVID and Fatiguing Illness Recovery Program (LC&FIRP) in a two-arm, single-blind, pragmatic, quality improvement, professional cluster, randomized controlled trial in which 20 consenting clinicians across primary care clinics in a Federally Qualified Health Center system in San Diego, CA, will be randomized at a ratio of 1:1 to either participate in (1) weekly multi-disciplinary team-based case consultation and peer-to-peer sharing of emerging best practices (i.e., teleECHO (Extension for Community Healthcare Outcomes)) with monthly interactive webinars and quarterly short courses or (2) monthly interactive webinars and quarterly short courses alone (a control group); 856 patients will be assigned to participating clinicians (42 patients per clinician). Patient outcomes will be evaluated according to the study arm of their respective clinicians. Quantitative and qualitative outcomes will be measured at 3- and 6-months post-baseline for clinicians and every 3-months post assignment to a participating clinician for patients. The primary patient outcome is change in physical function measured using the Patient-Reported Outcomes Measurement Information System (PROMIS)-29. Analyses of differences in outcomes at both the patient and clinician levels will include a linear mixed model to compare change in outcomes from baseline to each post-baseline assessment between the randomized study arms. A concurrent prospective cohort study will compare the LC&FIRP patient population to the population enrolled in a university health system. Longitudinal data analysis approaches will allow us to examine differences in outcomes between cohorts. DISCUSSION: We hypothesize that weekly teleECHO sessions with monthly interactive webinars and quarterly short courses will significantly improve clinician- and patient-level outcomes compared to the control group. This study will provide much needed evidence on the effectiveness of a technology-enabled multi-disciplinary team-based care model for the management of Long COVID, ME/CFS, and other PIFI within a federally qualified health center.

Persistent gaps exist in healthcare workers' capacity to address HIV and tuberculosis in Asia and Africa due to constraints in resources and knowledge. Project ECHO (Extension for Community Healthcare Outcomes) leverages video-enabled technology to build workforce capacity and promote collaboration through mentorship and case-based learning. To understand current perceptions of ECHO participants and develop a comprehensive evaluation framework for ECHO implementation, we utilized modified appreciative inquiry guided focus group discussions (FGD) in India and Tanzania and called it SCORE (Strengths, Challenges, Opportunities, Results, and Evaluation). Content and thematic analysis of transcripts from FGDs and key-informant interviews triangulated perceptions of diverse stakeholders about ECHO implementation and identified key elements for development of the framework. The perceived strengths (S) were capacity building and establishing communities of practice. The perceived challenges (C) included securing resources, engaging leadership, and building systems for monitoring impact. Improved internet connectivity, addressing logistical challenges, encouraging session interactivity, and having strategic scale-up plans were perceived opportunities (O). Additionally, gathering measurable results (R) led to development of a comprehensive evaluation (E) framework. Contextualizing and facilitating SCORE with qualitative analysis of findings 6-12months post-ECHO implementation may serve as a best practice to assess mid-course corrections to improve ECHO implementation quality.

Introduction: The United States Centers for Disease Control and Prevention (CDC), through U.S. President's Emergency Plan for AIDS Relief (PEPFAR), supports a third of all people receiving HIV care globally. CDC works with local partners to improve methods to find, treat, and prevent HIV and tuberculosis. However, a shortage of trained medical professionals has impeded efforts to control the HIV epidemic in Sub-Saharan Africa and Asia. The Project Extension for Community Healthcare Outcomes (ECHO(TM)) model expands capacity to manage complex diseases, share knowledge, disseminate best practices, and build communities of practice. This manuscript describes a practical protocol for an evaluation framework and toolkit to assess ECHO implementation. Methods and Analysis: This mixed methods, developmental evaluation design uses an appreciative inquiry approach, and includes a survey, focus group discussion, semi-structured key informant interviews, and readiness assessments. In addition, ECHO session content will be objectively reviewed for accuracy, content validity, delivery, appropriateness, and consistency with current guidelines. Finally, we offer a mechanism to triangulate data sources to assess acceptability and feasibility of the evaluation framework and compendium of monitoring and evaluation tools. Expected impact of the study on public health: This protocol offers a unique approach to engage diverse group of stakeholders using an appreciative inquiry process to co-create a comprehensive evaluation framework and a compendium of assessment tools. This evaluation framework utilizes mixed methods (quantitative and qualitative data collection tools), was pilot tested in Tanzania, and has the potential for contextualized use in other countries who plan to evaluate their Project ECHO implementation.

INTRODUCTION: The 2019 coronavirus (COVID-19) pandemic has been an unprecedented global health challenge. Traditional modes of knowledge dissemination have not been feasible. A rapid solution was needed to share guidance and implementation examples among the global Infection Prevention and Control (IPC) community. We designed the IPC Global Webinar Series to bring together subject matter experts and IPC professionals in the fight against COVID-19. METHODS: The Extension for Community Healthcare Outcomes (ECHO) model was adapted to create an interactive global knowledge network. Speakers and panelists provided presentations and answers to questions from participants. The webinars were simultaneously interpreted to five languages and recorded for later access. RESULTS: Thirteen webinar sessions were completed from May 14 through August 6, 2020. On average, 634 participants attended each session (range: 393 - 1,181). Each session was represented by participants from an average of over 100 countries; sessions 1-3 had participation from approximate 120 countries, and sessions 6 and 12 had participation from approximately 80 countries. DISCUSSION: The IPC Global Webinar Series shared critical information and promoted peer-to-peer learning during the COVID-19 pandemic response. The webinar sessions reached a broader audience than many in-person events. The webinar series was rapidly scaled and can be rapidly re-activated as needed. Our lessons learned in designing and implementing the series can inform design of other global health virtual knowledge networks. The continued and expanded use of adapted virtual communities of practice and other learning networks for the IPC community can serve as a valuable tool for addressing COVID-19 and other infectious disease threats.

BACKGROUND: The Namibian Ministry of Health and Social Services (MoHSS) piloted the first HIV Project ECHO (Extension for Community Health Outcomes) in Africa at 10 clinical sites between 2015 and 2016. Goals of Project ECHO implementation included strengthening clinical capacity, improving professional satisfaction, and reducing isolation while addressing HIV service challenges during decentralization of antiretroviral therapy. METHODS: MoHSS conducted a mixed-methods evaluation to assess the pilot. Methods included pre/post program assessments of healthcare worker knowledge, self-efficacy, and professional satisfaction; assessment of continuing professional development (CPD) credit acquisition; and focus group discussions and in-depth interviews. Analysis compared the differences between pre/post scores descriptively. Qualitative transcripts were analyzed to extract themes and representative quotes. RESULTS: Knowledge of clinical HIV improved 17.8% overall (95% confidence interval 12.2-23.5%) and 22.3% (95% confidence interval 13.2-31.5%) for nurses. Professional satisfaction increased 30 percentage points. Most participants experienced reduced professional isolation (66%) and improved CPD credit access (57%). Qualitative findings reinforced quantitative results. Following the pilot, the Namibia MoHSS Project ECHO expanded to over 40 clinical sites by May 2019 serving more than 140 000 people living with HIV. CONCLUSIONS: Similar to other Project ECHO evaluation results in the United States of America, Namibia's Project ECHO led to the development of ongoing virtual communities of practice. The evaluation demonstrated the ability of the Namibia HIV Project ECHO to improve healthcare worker knowledge and satisfaction and decrease professional isolation.

Across the lifespan, American Indian and Alaska Native (AI/AN) people have higher rates of chronic disease, injury, and premature death than some racial/ethnic groups in the United States (1,2). For example, AI/AN adults have a higher prevalence of obesity, are twice as likely to have diabetes, and are more likely to be current smokers than their non-Hispanic white counterparts (3). Rates of death due to stroke and heart disease are also higher among AI/ANs than among members of some racial and ethnic groups (4,5). | | Recognizing AI/AN communities have their own cultural strategies for chronic disease prevention and control, the Centers for Disease Control and Prevention (CDC) created the Good Health and Wellness in Indian Country (GHWIC) program to integrate the knowledge those communities possess into a coordinated approach to healthy living and chronic disease prevention. The program also sought to reinforce efforts in Indian Country to advance policy, systems, and environmental (PSE) improvements to make healthy choices easier for all community members.

Advances in medical research and innovation mean little if they do not reach the patients who need them. Too often, specialised medical knowledge remains within the walls of academic and tertiary care centres in capitals and major cities, inaccessible to much of the world’s population due to geographical distance and economic disparity. To “ensure healthy lives and promote well-being for all at all ages”, UN Sustainable Development Goal 3, a more efficient and equitable way to disseminate new scientific knowledge and evidence-based expertise is needed. | During the past two decades, technology-enhanced communication and collaborative learning initiatives have converged to produce innovative and powerful learning platforms. The rise of Internet-based communication has spurred a revolution in online education and knowledge sharing, from massive open online courses (MOOCs), such as Coursera, to online learning platforms (eg, Khan Academy) and continuing education resources (eg, the University of Washington’s HIV Web Study). Collaborative learning in health care has evolved rapidly; the Institute for Healthcare Improvement’s collaborative learning model offers one leading example.1 Telemedicine also allows long-distance training for health-care professionals,2 an effective method to deliver patient-centred, contextual medical curricula,3 and supportive supervision. Additionally, online social networking enables communities of practice4 that “offer the potential to bring together temporally and geographically dispersed actors to work towards a common purpose”.5 Through technology, communities of practice are being implemented across health-care areas, such as integrated care,6 pain management,7 health visiting services,8 and nurse education.9 These virtual communities enable collaborative learning that transcends geography.10

BACKGROUND: An estimated 120,000 HIV-associated cryptococcal meningitis (CM) cases occur each year in South and Southeast Asia; early treatment may improve outcomes. The World Health Organization (WHO) recently recommended screening HIV-infected adults with CD4<100 cells/mm(3) for serum cryptococcal antigen (CrAg), a marker of early cryptococcal infection, in areas of high CrAg prevalence. We evaluated CrAg prevalence and cost-effectiveness of this screening strategy in HIV-infected adults in northern and southern Vietnam. METHODS: Serum samples were collected and stored during 2009-2012 in Hanoi and Ho Chi Minh City, Vietnam, from HIV-infected, ART-naive patients presenting to care in 12 clinics. All specimens from patients with CD4<100 cells/mm(3) were tested using the CrAg lateral flow assay. We obtained cost estimates from laboratory staff, clinicians and hospital administrators in Vietnam, and evaluated cost-effectiveness using WHO guidelines. RESULTS: Sera from 226 patients [104 (46%) from North Vietnam and 122 (54%) from the South] with CD4<100 cells/mm(3) were available for CrAg testing. Median CD4 count was 40 (range 0-99) cells/mm(3). Nine (4%; 95% CI 2-7%) specimens were CrAg-positive. CrAg prevalence was higher in South Vietnam (6%; 95% CI 3-11%) than in North Vietnam (2%; 95% CI 0-6%) (p = 0.18). Cost per life-year gained under a screening scenario was $190, $137, and $119 at CrAg prevalences of 2%, 4% and 6%, respectively. CONCLUSION: CrAg prevalence was higher in southern compared with northern Vietnam; however, CrAg screening would be considered cost-effective by WHO criteria in both regions. Public health officials in Vietnam should consider adding cryptococcal screening to existing national guidelines for HIV/AIDS care.

OBJECTIVES: Vietnam has significantly scaled up its national antiretroviral therapy (ART) program since 2005. With the aim of improving Vietnam's national ART program, we conducted an outcome evaluation of the first five years of the program in this concentrated HIV epidemic where the majority of persons enrolled in HIV care and treatment services are people who inject drugs (PWID). The results of this evaluation may have relevance for other national ART programs with significant PWID populations. DESIGN: Retrospective cohort analysis of patients at 30 clinics randomly selected with probability proportional to size among 120 clinics with at least 50 patients on ART. METHODS: Charts of patients whose ART initiation was at least 6 months prior to the study date were abstracted. Depending on clinic size, either all charts or a random sample of 300 charts were selected. Analyses were limited to treatment-naive patients. Multiple imputations were used for missing data. RESULTS: Of 7,587 patient charts sampled, 6,875 were those of treatment-naive patients (74.4% male, 95% confidence interval [CI]: 72.4-76.5, median age 30, interquartile range [IQR]: 26-34, 62.0% reported a history of intravenous drug use, CI: 58.6-65.3). Median baseline CD4 cell count was 78 cells/mm (IQR: 30-162) and 30.4% (CI: 25.8-35.1) of patients were at WHO stage IV. The majority of patients started d4T/3TC/NVP (74.3%) or d4T/3TC/EFV (18.6%). Retention rates after 6, 12, 24, and 36 months were 88.4% (CI: 86.8-89.9), 84.0% (CI: 81.8-86.0), 78.8% (CI: 75.7-81.6), and 74.6% (CI: 69.6-79.0). Median CD4 cell count gains after 6, 12, 24, and 36 months were 94 (IQR: 45-153), 142 (IQR: 78-217), 213 (IQR: 120-329), and 254 (IQR: 135-391) cells/mm. Patients who were PWID showed significantly poorer retention. CONCLUSIONS: The study showed good retention and immunological response to ART among a predominantly PWID group of patients despite advanced HIV infections at baseline.
