Specialty Care Access Network-Extension of Community Healthcare Outcomes Model Program for Liver Disease Improves Specialty Care Access

Community Provider Perspectives on an Autism Learning Health Network: A Qualitative Study

Although autism is highly prevalent, no single care center has enough patients to produce generalizable knowledge of optimal care; this slows the pace of quality improvement research. The Autism Care Network (ACNet) is a learning health network (LHN) dedicated to developing the most effective approach to care for autistic children and adolescents through integrating clinical and research data. Given that most autistic patients receive care in the community, expanding ACNet to include community providers is essential to improve autism care. Our objectives were to: (1) understand the current data collection practices, learning needs, capacity, and overall interest of community clinicians in participating in an autism LHN; (2) identify their perspectives on participating in a LHN and ways in which their engagement and interest can be cultivated. Participants were purposively sampled from community physicians who participated in ASD-focused educational programming. In-depth semi-structured interviews were conducted. Analysis of 29 participant interviews yielded five primary themes: Navigating Administrative Challenges, Improving Data Collection Practices, Increasing Provider Confidence and Competence, Breaking Down Silos, and System and Societal Barriers to Achieving Best Practices. This study provides a rich and nuanced understanding of the experiences of community providers regarding the challenges of ASD care provision in the community. Overall, these findings suggest that LHNs have the potential to address several of the issues in community autism care highlighted by community providers.

Online palliative care education and mentorship in Nepal: Project ECHO - a novel approach to improving knowledge and self-efficacy among interprofessional health-care providers

BACKGROUND

Palliative care access in Nepal is severely limited, with few health-care providers having training and skills to pain management and other key aspects of palliative care. Online education suggests an innovation to increase access to training and mentoring, which addresses common learning barriers in low- and middle-income countries. Project ECHO (Extensions for Community Health Care Outcomes) is a model of online education which supports communities of practices (COPs) and mentoring through online teaching and case discussions. The use of online education and Project ECHO in Nepal has not been described or evaluated.

SETTING

An online course, consisting of 14 synchronous weekly palliative care training sessions was designed and delivered, using the Project ECHO format. Course participants included health-care professionals from a variety of disciplines and practice settings in Nepal.

OBJECTIVES

The goal of this study was to evaluate the impact of a virtual palliative care training program in Nepal on knowledge and attitudes of participants.

METHODS

Pre- and post-course surveys assessed participants' knowledge, comfort, and attitudes toward palliative care and evaluated program acceptability and barriers to learning.

RESULTS

Forty-two clinicians, including nurses (52%) and physicians (48%), participated in program surveys. Participants reported significant improvements in their knowledge and attitudes toward core palliative care domains. Most participants identified the program as a supportive COP, where they were able to share and learn from faculty and other participants.

CONCLUSION

Project ECHO is a model of online education which can successfully be implemented in Nepal, enhancing local palliative care capacity. Bringing together palliative care local and international clinical experts and teachers supports learning for participants through COP. Encouraging active participation from participants and ensuring that teaching addresses availability and practicality of treatments in the local health-care context addresses key barriers of online education.

SIGNIFICANCE OF RESULTS

This study describes a model of structured virtual learning program, which can be implemented in settings with limited access to palliative care to increase knowledge and attitudes toward palliative care. The program equips health-care providers to better address serious health-related suffering, improving the quality of life for patients and their caregivers. The program demonstrates a model of training which can be replicated to support health-care providers in rural and remote settings.

The impact of county-level food access on the mortality and post-transplant survival among patients with steatotic liver disease

BACKGROUND

The impact of county-level food access on mortality associated with steatotic liver disease, as well as post-liver transplant outcomes among individuals with steatotic liver disease, have not been characterized.

METHODS

Data on steatotic liver disease-related mortality and outcomes of liver transplant recipients with steatotic liver disease between 2010 and 2020 were obtained from the Centers for Disease Control Prevention mortality as well as the Scientific Registry of Transplant Recipients databases. These data were linked to the food desert score, defined as the proportion of the total population in each county characterized as having both low income and limited access to grocery stores.

RESULTS

Among 2,710 counties included in the analytic cohort, median steatotic liver disease-related mortality was 27.3 per 100,000 population (interquartile range 24.9-32.1). Of note, patients residing in counties with high steatotic liver disease death rates were more likely to have higher food desert scores (low: 5.0, interquartile range 3.1-7.8 vs moderate: 6.1, interquartile range, 3.8-9.3 vs high: 7.6, interquartile range 4.1-11.7). Among 28,710 patients who did undergo liver transplantation, 5,310 (18.4%) individuals lived in counties with a high food desert score. Liver transplant recipients who resided in counties with the worst food access were more likely to have a higher body mass index (>35 kg/m2: low food desert score, 17.3% vs highest food desert score, 20.1%). After transplantation, there was no difference in 2-year graft survival relative to county-level food access (food desert score: low: 88.4% vs high: 88.6%; P = .77).

CONCLUSION

Poor food access was associated with a higher incidence rate of steatotic liver disease-related death, as well as lower utilization of liver transplants. On the other hand, among patients who did receive a liver transplant, there was no difference in 2-year graft survival regardless of food access strata. Policy initiatives should target the expansion of transplantation services to vulnerable communities in which there is a high mortality of steatotic liver disease.

Liver transplantation access and outcomes: Impact of variations in liver-specific specialty care

BACKGROUND

We sought to characterize the impact access to gastroenterologists/hepatologists has on liver transplantation listing, as well as time on the liver transplantation waitlist and post-transplant outcomes.

METHODS

Liver transplantation registrants aged >18 years between January 1, 2004 and December 31, 2019 were identified from the Scientific Registry of Transplant Recipients Standard Analytic Files. The liver transplantation registration ratio was defined as the ratio of liver transplant waitlist registrations in a given county per 1,000 liver-related deaths.

RESULTS

A total of 150,679 liver transplantation registrants were included. Access to liver transplantation centers and liver-specific specialty physicians varied markedly throughout the United States. Of note, the liver transplantation registration ratio was lower in counties with poor access to liver-specific care versus counties with adequate access (poor access 137.2, interquartile range 117.8-163.2 vs adequate access 157.6, interquartile range 127.3-192.2, P < .001). Among patients referred for liver transplantation, the cumulative incidence of waitlist mortality and post-transplant graft survival was comparable among patients with poor versus adequate access to liver-specific care (both P > .05). Among liver transplantation recipients living in areas with poor access, after controlling for recipient and donor characteristics, cold ischemic time, and model for end-stage liver disease score, the area deprivation index predicted graft survival (referent, low area deprivation index; medium area deprivation index, hazard ratio 1.52, 95% confidence interval 1.03-12.23; high area deprivation index, 1.45, 95% confidence interval 1.01-12.09, both P < .05).

CONCLUSION

Poor access to liver-specific care was associated with a reduction in liver transplantation registration, and individuals residing in counties with high social deprivation had worse graft survival among patients living in counties with poor access to liver-specific care.

Evaluation of treatment access and scope of a multistate hepatitis C virus Extension for Community Healthcare Outcomes telehealth service in the US Indian Health System, 2017-2021

PURPOSE

American Indians/Alaska Native (AI/AN) persons are disproportionately affected by hepatitis C virus (HCV). The Northwest Portland Area Indian Health Board Indian Country Extension for Community Healthcare Outcomes (ECHO) telehealth clinic supports primary care providers (PCPs) in treating HCV. We evaluated the extent to which Indian Country ECHO increases access to HCV treatment and holistically serves AI/AN patients.

METHODS

We conducted a retrospective descriptive analysis of Indian Country ECHO treatment recommendations from 2017 to 2021. Recommendations were classified into the following categories: HCV treatment with direct-acting antiviral medication, prevention, substance use disorder treatment, lab or imaging orders, pharmacological considerations, behavior changes, other, and referral. Subanalysis of treatment recommendations was completed for patients with cirrhosis.

FINDINGS

Of the 776 patients from 77 Indian Health System facilities who presented at Indian Country ECHO, 718 (93%) received treatment recommendations. Most patients (93%) received recommendations for HCV treatment by their PCP; only 3% received a recommendation for referral to a hepatologist or liver transplant center for additional care. Most patients received at least 1 recommendation beyond the scope of HCV treatment provision. Cirrhosis criteria were met by 8% of patients, of which 80% received recommendations for HCV treatment by their PCP and 25% received recommendations for referral to a specialist for additional care.

CONCLUSIONS

Most patients presented at the Indian Country ECHO received recommendations for HCV treatment by their PCP, along with recommendations beyond the scope of HCV. Indian Country ECHO telehealth clinic provides comprehensive recommendations to effectively integrate evidence-based HCV treatment with holistic care at the primary care level.

Access to technology to support telehealth in areas without specialty care for liver disease

BACKGROUND AND AIMS

Telehealth may be a successful strategy to increase access to specialty care for liver disease, but whether the areas with low access to care and a high burden of liver-related mortality have the necessary technology access to support a video-based telehealth strategy to expand access to care is unknown.

APPROACH AND RESULTS

Access to liver disease specialty care was defined at the county level as <160.9 km (100 miles) from a liver transplant (LT) center or presence of local gastroenterology (GI). Liver-related mortality rates were compared by access to care, and access to technology was compared by degree of access to care and burden of liver-related mortality. Counties with low access to liver disease specialty care had higher rates of mortality from liver disease, and this was highest in areas both >160.9 km from an LT center and without local GI. These counties were more rural, had higher poverty, and had decreased access to devices and internet at broadband speeds. Technology access was lowest in areas with low access to care and the highest burden of liver-related mortality.

CONCLUSIONS

Areas with poor access to liver disease specialty care have a greater burden of liver-related mortality, and many of their residents lack access to technology. Therefore, a telehealth strategy based solely on patient device ownership and internet access will exclude a large proportion of individuals in the areas of highest need. Further work should be done at the local and state levels to design optimal strategies to reach their populations of need.

The perceived impact of project ECHO networks in Northern Ireland for health and social care providers, patients, and the health system: A qualitative analysis

This study assesses the perceived impact and benefits of Project ECHO (Extension for Community Healthcare Outcomes), a tele-mentoring intervention for health and social care providers, patients and the health system in Northern Ireland. Having access to a specialist, a space to share experiences, and being able to disseminate up-to-date best practice were all cited as improving provider knowledge as well as improving quality of care for patients. Healthcare providers reported being more confident in managing patients and that relationships had been improved between different levels of the health system. ECHO was described as improving access to education and training by removing geographic and time barriers. This is one of the first studies to qualitatively analyse impact across a number of different clinical and social care ECHO networks. The results strongly indicate the perceived benefit of ECHO in improving provider, patient and health system outcomes such as increased healthcare provider knowledge and confidence to manage patients at primary levels of the health system. This has implications for future service design, particularly within the context of COVID-19 in which virtual and online training is necessitated by social distancing requirements.

Direct and Indirect Effects of a Project ECHO Longitudinal Clinical Tele-Mentoring Program on Viral Suppression for Persons With HIV: A Population-Based Analysis

BACKGROUND

Project Extension for Community Health Outcomes (ECHO) aims to connect community providers to academic specialists, deliver longitudinal clinical mentorship and case consultations, plus encourage dissemination of knowledge and resources. The impact on outcomes for persons with HIV (PWH) is uncertain.

SETTING

PWH in Washington and Oregon outside of the Seattle and Portland metro areas, January 2011 to March 2018.

METHODS

Using viral load (VL) surveillance data, we assessed difference in the percentage of PWH who were virally suppressed among PWH whose providers participated versus did not participate in Project ECHO. Analyses included multiple mixed-effects regression models, adjusting for time and for patient, provider, and clinic characteristics.

RESULTS

Based on 65,623 VL results, Project ECHO participation was associated with an increase in the percentage of patients with VL suppression (13.7 percentage points greater; P < 0.0001), although the effect varied by estimated provider PWH patient volume. The difference was 14.7 percentage points ( P < 0.0001) among patients of providers who order <20 VL's/quarter and 2.3 and -0.6 percentage points among patients of providers who order 20-40 or >40 VL's/quarter, respectively ( P > 0.5). The magnitude of difference in VL suppression was associated with the number of sessions attended. Among patients of lower-volume providers who did not participate, VL suppression was 6.2 percentage points higher if providers worked in a clinic where another provider did participate ( P < 0.0001).

CONCLUSION

Project ECHO is associated with improvement in VL suppression for PWH whose providers participate or work in the same clinic system as a provider who participates, primarily because of benefits for patients of lower-volume providers.

Feasibility, acceptability, and sustainability of Project ECHO to expand capacity for pediatricians in Vietnam

Background

The Project Extension for Community Healthcare Outcomes (ECHO) model is considered a platform for academic medical centers to expand their healthcare workforce capacity to medically underserved populations. It has been known as an effective solution of continuing medical education (CME) for healthcare workers that used a hub-and-spoke model to leverage knowledge from specialists to primary healthcare providers in different regions. In this study, we aim to explore the views of healthcare providers and hospital leaders regarding the feasibility, acceptability, and sustainability of Project ECHO for pediatricians.

Methods

This qualitative study was conducted at the Vietnam National Children’s Hospital and its satellite hospitals from July to December 2020. We conducted 39 in-depth interviews with hospital managers and healthcare providers who participated in online Project ECHO courses. A thematic analysis approach was performed to extract the qualitative data from in-depth interviews.

Results

Project ECHO shows high feasibility when healthcare providers find motivated to improve their professional knowledge. Besides, they realized the advantages of saving time and money with online training. Although the courses had been covered fully by the Ministry of Health’s fund, the participants said they could pay fees or be supported by the hospital’s fund. In particular, the expectation of attaining the CME-credited certificates after completing the course also contributes to the sustainability of the program. Project ECHO’s online courses should be improved if the session was better monitored with suitable time arrangements.

Conclusions

Project ECHO model is highly feasible, acceptable, and sustainable as it brings great benefits to the healthcare providers, and is appropriate with the policy theme of continuing medical education of the Ministry of Health. We recommend that further studies should be conducted to assess the impact of the ECHO program, especially for patient and community outcomes.

Use of Project ECHO Telementoring Model in Continuing Medical Education for Pediatricians in Vietnam: Preliminary Results

The ECHO (Extension for Community Health Outcomes) model has been introduced and implemented in several hospitals and health programs in Vietnam since 2015. In 2018, Vietnam National Children’s Hospital (VNCH) officially implemented the ECHO model to provide continuing medical education (CME) credits on pediatrics topics for medical staff in its satellite hospitals and health centers in the Northern region of Vietnam. This paper presents preliminary results of the ECHO program at VNCH. Methods included pre- and post-program assessments of pediatricians’ clinical knowledge, self-efficacy, and professional satisfaction. The analysis compared the differences between pre/post scores descriptively. Knowledge of participants increased by 22.5% points on average. More than 90% of Project ECHO-Pediatrics participants experienced increased confidence. Overall, there was an improvement in participants’ self-efficacy in the post-training compared to the pre-training (range 14.7%-22.6% difference from pre-training). All participants improved on their results in the clinical test immediately after the training and maintained it after 3 months. The study demonstrated the ability Project ECHO to improve healthcare worker knowledge and satisfaction.

Extension for Community Healthcare Outcomes-Palliative Care in Africa Program: Improving Access to Quality Palliative Care

PURPOSE

There is limited access to quality palliative care (PC) for patients with advanced cancer in sub-Saharan Africa. Our aim was to describe the development of the Project Extension for Community Healthcare Outcomes-Palliative Care in Africa (ECHO-PACA) program and describe a preliminary evaluation of attitudes and knowledge of participants regarding the ability of the program to deliver quality PC.

METHODS

An interdisciplinary team at the MD Anderson Cancer Center, guided by experts in PC in sub-Saharan Africa, adapted a standardized curriculum based on PC needs in the region. Participants were then recruited, and monthly telementoring sessions were held for 16 months. The monthly telementoring sessions consisted of case presentations, discussions, and didactic lectures. Program participants came from 14 clinics and teaching hospitals in Ghana, Kenya, Nigeria, South Africa, and Zambia. Participants were surveyed at the beginning, midpoint, and end of the 16-month program to evaluate changes in attitudes and knowledge of PC.

RESULTS

The median number of participants per session was 30. Thirty-three (83%) of 40 initial participants completed the feedback survey. Health care providers’ self-reported confidence in providing PC increased with participation in the Project ECHO-PACA clinic. There was significant improvement in the participants’ attitudes and knowledge, especially in titrating opioids for pain control (P = .042), appropriate use of non-opioid analgesics (P = .012), and identifying and addressing communication issues related to end-of-life care (P = .014).

CONCLUSION

Project ECHO-PACA was a successful approach for disseminating knowledge about PC. The participants were adherent to ECHO PACA clinics and the completion of feedback surveys. Future studies should evaluate the impact of Project ECHO-PACA on changes in provider practice as well as patient outcomes.

Telemedicine Improves Access to Hepatology Consultation with High Patient Satisfaction

AIMS

Telemedicine between health care providers could be useful for improving the access to hepatology consultations, which is challenging in some regions. The primary objective of this study was to estimate the proportion of consultations that were resolved through a telemedicine program. Additionally, we evaluated patient satisfaction with this strategy.

METHODS

Consecutive telemedicine consultations made by non-hepatologist health care providers from different regions of Argentina to a specialty hepatology team were included. Participants and hepatologists used e-mail, teleconference systems, WhatsApp, or telephone to interact, depending on their preferences. Consultations were considered to be resolved through telemedicine when a diagnosis and an adequate follow-up were achieved without the need to refer the patient to a hepatologist or other specialist. Patient satisfaction with telemedicine was evaluated using the Patient Satisfaction Questionnaire Short Form and Telemedicine Satisfaction Questionnaire.

RESULTS

A total of 200 telemedicine consultations made by 24 physicians from 10 different provinces of Argentina were evaluated, of which 145 (73%; 95% CI: 66%-79%) were resolved through telemedicine. Practitioners specialities were as follows: family physicians, internists, gastroenterologists, infectious diseases, and obstetrics. The most frequent final diagnoses for those patients whose consultation was resolved through telemedicine were non-alcoholic fatty liver disease, viral hepatitis, and benign hepatic lesions. A high degree of patient satisfaction with telemedicine was observed in both questionnaires.

CONCLUSIONS

Our results show the effectiveness of telemedicine in hepatology, with high resolution rate of consultations and rapid access to experts' assessment. Additionally, a high degree of patient satisfaction was observed using prevalidated questionnaires.

Impact of Project ECHO Models of Medical Tele-Education: a Systematic Review

BACKGROUND

Extension for Community Healthcare Outcomes (ECHO) and related models of medical tele-education are rapidly expanding; however, their effectiveness remains unclear. This systematic review examines the effectiveness of ECHO and ECHO-like medical tele-education models of healthcare delivery in terms of improved provider- and patient-related outcomes.

METHODS

We searched English-language studies in PubMed, Embase, and PsycINFO databases from 1 January 2007 to 1 December 2018 as well as bibliography review. Two reviewers independently screened citations for peer-reviewed publications reporting provider- and/or patient-related outcomes of technology-enabled collaborative learning models that satisfied six criteria of the ECHO framework. Reviewers then independently abstracted data, assessed study quality, and rated strength of evidence (SOE) based on Cochrane GRADE criteria.

RESULTS

Data from 52 peer-reviewed articles were included. Forty-three reported provider-related outcomes; 15 reported patient-related outcomes. Studies on provider-related outcomes suggested favorable results across three domains: satisfaction, increased knowledge, and increased clinical confidence. However, SOE was low, relying primarily on self-reports and surveys with low response rates. One randomized trial has been conducted. For patient-related outcomes, 11 of 15 studies incorporated a comparison group; none involved randomization. Four studies reported care outcomes, while 11 reported changes in care processes. Evidence suggested effectiveness at improving outcomes for patients with hepatitis C, chronic pain, dementia, and type 2 diabetes. Evidence is generally low-quality, retrospective, non-experimental, and subject to social desirability bias and low survey response rates.

DISCUSSION

The number of studies examining ECHO and ECHO-like models of medical tele-education has been modest compared with the scope and scale of implementation throughout the USA and internationally. Given the potential of ECHO to broaden access to healthcare in rural, remote, and underserved communities, more studies are needed to evaluate effectiveness. This need for evidence follows similar patterns to other service delivery models in the literature.

Effect of travel distance and rurality of residence on initial surveillance for hepatocellular carcinoma in VA primary care patient with cirrhosis

OBJECTIVE

To determine the relationship between travel distance and surveillance for hepatocellular carcinoma among veterans with cirrhosis.

DATA SOURCES

Veterans Health Administration (VHA) inpatient and outpatient administrative data were linked to geocoded enrollee files. CMS-VHA merged data were used to assess receipt of Medicare-financed non-VA imaging.

STUDY DESIGN

A retrospective cohort of US veterans diagnosed with cirrhosis between 2009 and 2015 was examined. First available abdominal imaging following the diagnosis of cirrhosis was analyzed separately as a function of travel distance to the nearest VA medical center (VAMC) and to the patient's assigned VA primary care provider. Veterans with dual use of Medicare and VA services were also examined for receipt of imaging outside of the VA.

PRINCIPAL FINDINGS

Veterans who resided more than 30 miles from the nearest VAMC were less likely to receive any imaging for HCC surveillance. Among dual users, increased travel distance between the patient's residence and nearest VAMC was associated with an increased likelihood of receiving any abdominal imaging at non-VA facilities.

CONCLUSION

Increased travel distance to the nearest VA medical center reduces the likelihood of receiving imaging for HCC surveillance in cirrhotic veterans. Future efforts should focus on reducing geographic barriers to HCC surveillance.

Phosphodiesterase-5 Inhibitor Therapy for Pulmonary Hypertension in the United States. Actual versus Recommended Use

RATIONALE

Care of patients with pulmonary hypertension is complex. Although pulmonary vasodilators are effective for Group 1 pulmonary hypertension, clinical guidelines and the Choosing Wisely Campaign recommend against routine use for Groups 2 and 3 pulmonary hypertension (the most common types of pulmonary hypertension) because of a lack of benefit, potential for harm, and high cost ($10,000-$13,000 per patient per year treated). Little is known about how these medications are used in practice.

OBJECTIVES

To determine national patterns of phosphodiesterase-5 inhibitor prescribing for pulmonary hypertension in the Veterans Health Administration.

METHODS

Retrospective analysis of Veterans prescribed phosphodiesterase-5 inhibitor for pulmonary hypertension between 2005 and 2012 at any Veterans Health Administration site. Patients were identified by presence of an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for pulmonary hypertension and one or more outpatient prescriptions for daily phosphodiesterase-5 inhibitor therapy. We developed and validated, using gold-standard chart abstraction, an International Classification of Diseases, Ninth Revision, Clinical Modification-based algorithm to assign pulmonary hypertension group. Our primary outcome was the proportion of patients who received potentially inappropriate phosphodiesterase-5 inhibitor, as determined by guideline recommendations (Group 1 pulmonary hypertension: appropriate; Groups 2/3: potentially inappropriate; Groups 4/5: uncertain value), among all patients prescribed phosphodiesterase-5 inhibitor for pulmonary hypertension. Secondary outcomes included proportion of treated patients who received guideline-recommended right heart catheterization.

RESULTS

Among 108,777 Veterans with pulmonary hypertension, 2,790 (2.6% [95% confidence interval, 2.5-2.7%]) received daily phosphodiesterase-5 inhibitor therapy. Among treated patients, 541 (19.4% [95% confidence interval, 18.0-20.9%]) received appropriate treatment, 1,711 (61.3% [95% confidence interval, 59.5-63.1%]) potentially inappropriate treatment, and 358 (12.8% [95% confidence interval, 11.6-14.1%]) treatment of uncertain value. The number of potentially inappropriately treated patients per year increased substantially over the study period (53 in 2005, 748 in 2012). On the basis of chart abstraction in a randomly selected subset of patients treated with phosphodiesterase-5 inhibitor, half (110 of 230, 47.8% [95% confidence interval, 41.3-54.5%]) had documented right heart catheterization to confirm presence or type of pulmonary hypertension. After factoring presence of and data from right heart catheterization into our treatment appropriateness algorithm, only 11.7% (95% confidence interval, 8.0-16.8%) received clearly appropriate treatment.

CONCLUSIONS

Most Veterans with pulmonary hypertension do not receive phosphodiesterase-5 inhibitor therapy. However, among treated Veterans, almost two-thirds of phosphodiesterase-5 inhibitor prescriptions are inconsistent with pulmonary hypertension guidelines, exposing patients to potential harm and creating a financial burden on the healthcare system. Further study is warranted to clarify the effects of these prescription patterns on pulmonary hypertension outcomes.

Telehealth-Based Evaluation Identifies Patients Who Are Not Candidates for Liver Transplantation

The burden of chronic liver disease has increased exponentially, driving more patients toward orthotopic liver transplant (OLT) evaluation.¹ Because of limited access to transplant centers, patients often travel long distances to be evaluated for OLT.² Liver transplantation in the VA system is offered at 6 Veterans Affairs transplant centers (VATCs) across the United States, including Richmond. To increase access to specialty care, the VA introduced the Specialty Care Access Network-Extension of Community Healthcare Outcomes (SCAN-ECHO) program,^3,4 which was designed to transfer subspecialty knowledge to primary care physicians. In 2011, the Richmond VA introduced SCAN-ECHO for gastroenterology/hepatology providers to facilitate case-based distance learning combined with real-time consultation in hepatology, and the opportunity for an initial triage without completing a formal transplant evaluation. We studied the role of SCAN-ECHO in triaging OLT evaluations and the utility of this health care delivery in the field of transplantation.

Virtual Consultations Through the Veterans Administration SCAN-ECHO Project Improves Survival for Veterans With Liver Disease

Access to specialty care has been associated with improved survival in patients with liver disease but universal access is not always feasible. Methods of care delivery using virtual modalities including the SCAN-ECHO (Specialty Access Network-Extension of Community Healthcare Outcome) program were implemented by the Veterans Health Administration (VHA) to address this need but limited data are available on patient outcomes. We sought to evaluate the efficacy of a SCAN-ECHO visit within the context of a regional cohort of patients with liver disease in the VHA (n = 62,237) following implementation in the Ann Arbor SCAN-ECHO Liver Clinic from June 1, 2011, to March 31, 2015. The effect of a SCAN-ECHO visit on all-cause mortality was compared with patients with no liver clinic visit. To adjust for the differences among patients who had a SCAN-ECHO visit versus those with no visit, propensity score matching was performed on condition factors that affect the likelihood of a SCAN-ECHO visit: demographics, geographic location, liver disease diagnosis, severity, and comorbidities. During the study period, 513 patients who had a liver SCAN-ECHO visit were found within the cohort. Patients who had completed a virtual SCAN-ECHO visit were more likely younger, rural, with more significant liver disease, and evidence for cirrhosis. Propensity-adjusted mortality rates using the Cox Proportional Hazard Model showed that a SCAN-ECHO visit was associated with a hazard ratio of 0.54 (95% confidence interval 0.36-0.81, P = 0.003) compared with no visit. Conclusion: Improved survival in patients using SCAN-ECHO suggests that this approach may be an effective method to improve access for selected patients with liver disease, particularly in rural and underserved populations where access to specialty care is limited.

A pilot study using telehealth to implement antimicrobial stewardship at two rural Veterans Affairs medical centers

OBJECTIVE

To test the feasibility of using telehealth to support antimicrobial stewardship at Veterans Affairs medical centers (VAMCs) that have limited access to infectious disease-trained specialists.

DESIGN

A prospective quasi-experimental pilot study.

SETTING

Two rural VAMCs with acute-care and long-term care units.InterventionAt each intervention site, medical providers, pharmacists, infection preventionists, staff nurses, and off-site infectious disease physicians formed a videoconference antimicrobial stewardship team (VAST) that met weekly to discuss cases and antimicrobial stewardship-related education.

METHODS

Descriptive measures included fidelity of implementation, number of cases discussed, infectious syndromes, types of recommendations, and acceptance rate of recommendations made by the VAST. Qualitative results stemmed from semi-structured interviews with VAST participants at the intervention sites.

RESULTS

Each site adapted the VAST to suit their local needs. On average, sites A and B discussed 3.5 and 3.1 cases per session, respectively. At site A, 98 of 140 cases (70%) were from the acute-care units; at site B, 59 of 119 cases (50%) were from the acute-care units. The most common clinical syndrome discussed was pneumonia or respiratory syndrome (41% and 35% for sites A and B, respectively). Providers implemented most VAST recommendations, with an acceptance rate of 73% (186 of 256 recommendations) and 65% (99 of 153 recommendations) at sites A and B, respectively. Qualitative results based on 24 interviews revealed that participants valued the multidisciplinary aspects of the VAST sessions and felt that it improved their antimicrobial stewardship efforts and patient care.

CONCLUSIONS

This pilot study has successfully demonstrated the feasibility of using telehealth to support antimicrobial stewardship at rural VAMCs with limited access to local infectious disease expertise.
