Tumor marker testing among Medicare beneficiaries with cancer after changes in insurance coverage for testing.

e13656 Background: Precision medicine has changed treatment practices for patients with cancer, and clinical guidelines now recommend tumor marker testing. Studies have demonstrated that tumor marker testing increases use of appropriate targeted therapies which is associated with improved survival, particularly among patients with advanced or metastatic cancer. In March 2018, Medicare issued a national coverage determination (NCD) for next-generation sequencing to facilitate tumor marker testing. We conducted a retrospective study to assess tumor marker testing among Medicare beneficiaries with cancer from 03/01/2016 through 02/29/2020. Methods: Data were obtained from the Virtual Data Warehouses of 6 United States (US) healthcare systems in the Health Care Systems Research Network, a well-established distributed data network for cancer research. Together these systems provide care to a diverse population of over 5.5 million people in the US. The index date for each individual was the first observed cancer diagnosis date recorded in the tumor registry during the study period. Subgroup analyses included those with lung, breast, colorectal, or prostate cancers, or those with advanced, metastatic or recurrent cancer. This is part of a larger project that aims to advance methods for scalable and rigorous evaluation of outcomes of coverage policies for genetic tests. Results: We report initial results from three health systems (03/01/2016-02/29/2020) including Medicare beneficiaries ≥65 years and ≥90 enrollment days on/after the index date. There were 10,048 Medicare beneficiaries with cancer in the pre-policy period (48.2% were female and mean [SD] age was 75 [6.9] years), and 7,160 Medicare beneficiaries with cancer in the post-policy period (47.7% were women and mean [SD] age was 75 [6.8] years). In the pre-policy period, 15.4% had a tumor marker test on/after 90 days of the index date, which increased by 1.7% to 17.1% after the policy (p<0.0001); and 47.9% started a cancer drug therapy on/after 90 days of the index date, which increased by 4.1% to 52.1% after the policy (p<0.0001), adjusting for age and sex and cancer type. Among Medicare beneficiaries with advanced, metastatic or recurrent cancer, 20.9% had a tumor marker test within 90 days of the index date in the pre-policy period, which increased by 3.0% to 23.9% after the policy (p= 0.009), and 65.1% started a cancer drug therapy on/after 90 days of the index date, which increased by 6.3% to 71.4% after the policy (p<0.0001), adjusting for age, sex, Charlson score, and cancer type. Conclusions: Tumor marker testing rate among Medicare beneficiaries with cancer in these health systems increased after the implementation of the 2018 Medicare NCD. Analyses are underway to examine changes in tumor marker testing, cancer treatments, and outcomes among Medicare beneficiaries by cancer type after the implementation of the 2018 Medicare NCD.

Partnering to Advance Health Equity and a Welcome Opportunity to Gather: Proceedings From the 28th Annual Conference of the Health Care Systems Research Network.

In April 2022, the Health Care Systems Research Network (HCSRN) - a consortium of 20 research institutions affiliated with large health systems spread across the United States (and one in Israel) - held its 28th annual conference in Pasadena, California, with 275 researchers, health care colleagues, and external academic partners in attendance. With a conference theme of "Promoting Collaboration and Partnerships to Advance Health Equity," the scientific program was assembled by a multisite planning committee with input from representatives of informal local host Kaiser Permanente Southern California. Objectives of the annual conference are to showcase scientific findings from HCSRN projects and to spur collaboration on research initiatives that improve health and health care for individuals and populations. To those ends, the NIH Pragmatic Trials Collaboratory sponsored a preconference workshop on the essentials of embedded pragmatic clinical trials, and more than a dozen scientific interest groups and active research project teams held ancillary sessions throughout the conference. This welcome opportunity for network members to meet in-person followed a 2-year hiatus necessitated by the COVID-19 pandemic, during which HCSRN conference proceedings were conducted through virtual and written communication platforms.

Demographic differences in willingness to share electronic health records in the All of Us Research Program.

Participant willingness to share electronic health record (EHR) information is central to success of the National Institutes of Health All of Us Research Program (AoURP). We describe the demographic characteristics of participants who decline access to their EHR data. We included participants enrolling in AoURP between June 6, 2017 and December 31, 2019 through the Trans-American Consortium for the Health Care Systems Research Network (TACH). TACH is a consortium of health care systems spanning 6 states, and an AoURP research partner. We analyzed data for 25 852 participants (89.3% of those enrolled). Mean age = 52.0 years (SD 16.8), with 66.5% White, 18.7% Black/African American, 7.7% Hispanic, 32.5% female, and 76% with >a high school diploma. Overall, 2.3% of participants declined to share access to their EHR data (range across TACH sites = 1.3% to 3.5%). Younger age, female sex, and education >high school were significantly associated with decline to share EHR data, odds ratio (95% confidence interval) = 1.26 (1.19-1.33), 1.74 (1.42-2.14), and 2.44 (1.86-3.21), respectively. Results were similar when several sensitivity analyses were performed. AoURP seeks a dataset reflecting our nation's diversity in all aspects of participation. Those under-represented in biomedical research may be reluctant to share access to their EHR data. In our data, race and ethnicity were not independently related to participant decision to decline access to their EHR information. Results suggest that the value of the AoURP dataset is unlikely to be constrained by the size or the racial/ethnic composition of this subgroup.

The geriatrics research instrument library: A resource for guiding instrument selection for researchers studying older adults with multiple chronic conditions.

BackgroundAfter the passage of the 21st Century Cures Act in the U.S., the Inclusion Across the Lifespan policy eliminates upper-age limits for research participation unless risk justified. Broader inclusion will necessitate the use of reliable instruments in research that characterize the health status and function of older adults with multiple chronic conditions. As there is a plethora of such instruments, the Geriatrics Research Instrument Library (GRIL) was developed as freely available online resource of data collection instruments commonly used in gerontological research. GRIL has been revised and updated by the Advancing Geriatrics Infrastructure and Network Growth (AGING) Initiative, a joint endeavor of the Health Care Systems Research Network (HCSRN) and the Older Americans Independence Centers (OAICs).MethodsExtensive PubMed literature searches and domain expert feedback were utilized to inventory and update GRIL through the addition of instruments and compiling of instrument metadata. GRIL is hosted on the National Institute on Aging OAIC Coordinating Center website with a platform utilizing Microsoft Structured Query Language (SQL) and an Adobe ColdFusion application server. Tracking statistics are collected using Google Analytics.ResultsPresently, GRIL includes 175 instruments across 18 domains, including instrument metadata such as instrument description, copyright information, completion time estimates, keywords, available translations, and a link and reference to the original manuscript describing the instrument. The GRIL website includes user-friendly features such as mobile platforming and resource links.ConclusionsGRIL provides a user-friendly public resource that facilitates clinical researchers in efficiently selecting appropriate instruments to measure clinical outcomes relevant to older adults across a full range of domains.

Association of Cardiovascular Outcomes and Mortality With Sustained Long-Acting Insulin Only vs Long-Acting Plus Short-Acting Insulin Treatment

Cardiovascular events and mortality are the principal causes of excess mortality and health care costs for people with type 2 diabetes. No large studies have specifically compared long-acting insulin alone with long-acting plus short-acting insulin with regard to cardiovascular outcomes. To compare cardiovascular events and mortality in adults with type 2 diabetes receiving long-acting insulin who do or do not add short-acting insulin. This retrospective cohort study emulated a randomized experiment in which adults with type 2 diabetes who experienced a qualifying glycated hemoglobin A1c (HbA1c) level of 6.8% to 8.5% with long-acting insulin were randomized to continuing treatment with long-acting insulin (LA group) or adding short-acting insulin within 1 year of the qualifying HbA1c level (LA plus SA group). Retrospective data in 4 integrated health care delivery systems from the Health Care Systems Research Network from January 1, 2005, to December 31, 2013, were used. Analysis used inverse probability weighting estimation with Super Learner for propensity score estimation. Analyses took place from April 1, 2018, to June 30, 2019. Long-acting insulin alone or with added short-acting insulin within 1 year from the qualifying HbA1c level. Mortality, cardiovascular mortality, acute myocardial infarction, stroke, and hospitalization for heart failure. Among 57 278 individuals (39 279 with data on cardiovascular mortality) with a mean (SD) age of 60.6 (11.5) years, 53.6% men, 43.5% non-Hispanic White individuals, and 4 years of follow-up (median follow-up of 11 [interquartile range, 5-20] calendar quarters), the LA plus SA group was associated with increased all-cause mortality compared with the LA group (hazard ratio, 1.27; 95% CI, 1.05-1.49) and a decreased risk of acute myocardial infarction (hazard ratio, 0.89; 95% CI, 0.81-0.97). Treatment with long-acting plus short-acting insulin was not associated with increased risks of congestive heart failure, stroke, or cardiovascular mortality. Findings of this retrospective cohort study suggested an increased risk of all-cause mortality and a decreased risk of acute myocardial infarction for the LA plus SA group compared with the LA group. Given the lack of an increase in major cardiovascular events or cardiovascular mortality, the increased all-cause mortality with long-acting plus short-acting insulin may be explained by noncardiovascular events or unmeasured confounding.

Learning Health System in Crisis: Lessons From the COVID-19 Pandemic.

The novel coronavirus disease (COVID-19) pandemic is the gravest public-health crisis that the United States has seen in more than a century. Healthcare delivery systems are the focal point for interfacing with COVID-19; however, many were and remain unprepared for this or similar outbreaks. In this paper, we describe the Learning Health System (LHS) as an ideal organizing principle to inform an evidence-based response to public-health emergencies like COVID-19. We further describe barriers and challenges to the realization of the LHS and propose a call to action for a substantial investment in the LHS, with a focus on public health. Specifically, we advocate for a Learning Health Network that promotes collaboration between health systems, community-based organizations, and government agencies, especially during public health emergencies. We have approached this commentary through the unique lens of researchers embedded within a large, integrated healthcare delivery system, with direct experience working with clinical and operational units in response to the COVID-19 pandemic.

Celebrating a Quarter-Century of Public Domain Research: 25th Annual Conference of the Health Care Systems Research Network.

The 25th annual conference of the Health Care Systems Research Network (HCSRN) was held April 10-12 in Portland, Oregon, attracting 420 attendees. The HCSRN, a consortium of 18 community-based research organizations embedded in or affiliated with large health care delivery systems, has hosted annual research conferences since 1994. The primary objective of the conference is to convene researchers, project staff, funders, and other stakeholders to share latest scientific findings and cultivate new partnerships among research teams, patients, and clinicians. Collaboration is the cornerstone of the HCSRN's success; the conference serves as a catalyst for a variety of collaborative ventures as well as tactics and approaches to more effective and efficient research. This year's program included 70 distinct scientific presentations, plus nearly 100 posters, and spanned diverse content offerings that mirrored the diversity of the HCSRN and its collaborators. Plenary sessions imparted insights on ways that data science and approaches to collaborative design in health care can speed the translation of research into practice.

We've Only Just Begun - Insights from a 25-Year Journey to Accelerate Health Care Transformation Through Delivery System Research.

Even though it is well known that quality, safety, and patient-centeredness of health care can be improved, leveraging the organizational apparatus of a care delivery environment to render improvement in a consistent and comprehensive manner has proven difficult. The Health Care Systems Research Network (HCSRN), which began as the HMO Research Network, emerged from a desire to improve health and study problems in health care in a systematic and collaborative way, spurring the delivery of true evidence-informed medicine. The HCSRN has honed network-wide data resources, a collaborative culture, and shared infrastructure, enabling multicenter health care research that is often more difficult for researchers working in less integrated settings and across organizational boundaries. The HCSRN’s 25-year track record confers both an opportunity and obligation to share what we have learned through our research. Considering the quarter-century since the HCSRN was established, we describe three evolving areas—health data, new health care models, and diversified research teams that must be thoughtfully harnessed to realize a transformed health care ecosystem that generates and learns with research.

Development of a Clinical Decision Support System for Pediatric Abdominal Pain in Emergency Department Settings Across Two Health Systems Within the HCSRN.

Background:Appendicitis is a common surgical emergency in children, yet diagnosis can be challenging. An electronic health record (EHR) based, clinical decision support (CDS) system called Appy CDS was designed to help guide management of pediatric patients with acute abdominal pain within the Health Care Systems Research Network (HCSRN).Objectives:To describe the development and implementation of a clinical decision support tool (Appy CDS) built independently but synergistically at two large HCSRN affiliated health systems using well-established platforms, and to assess the tool’s Triage component, aiming to identify pediatric patients at increased risk for appendicitis.Results:Despite differences by site in design and implementation, such as the use of alerts, incorporating gestalt, and other workflow variations across sites, using simple screening questions and automated exclusions, both systems were able to identify a population with similar appendicitis rates (11.8 percent and 10.6 percent), where use of the full Appy CDS would be indicated.Discussion:These 2 HCSRN sites designed Appy CDS to capture a population at risk for appendicitis and deliver CDS to that population while remaining locally relevant and adhering to organizational preferences. Despite different approaches to point-of-care CDS, the sites have identified similar cohorts with nearly identical background rates of appendicitis.Next Steps:The full Appy CDS tool, providing personalized risk assessment and tailored recommendations, is undergoing evaluation as part of a pragmatic cluster randomized trial aiming to reduce reliance on advanced diagnostic imaging. The novel approaches to CDS we present could serve as the basis for future ED interventions.

Priorities Wizard: Multisite Web-Based Primary Care Clinical Decision Support Improved Chronic Care Outcomes with High Use Rates and High Clinician Satisfaction Rates.

Introduction:Priorities Wizard is an electronic health record-linked, web-based clinical decision support (CDS) system designed and implemented at multiple Health Care Systems Research Network (HCSRN) sites to support high quality outpatient chronic disease and preventive care. The CDS system (a) identifies patients who could substantially benefit from evidence-based actions; (b) presents prioritized evidence-based treatment options to both patient and clinician at the point of care; and (c) facilitates efficient ordering of recommended medications, referrals or procedures.Methods:The CDS system extracts relevant data from electronic health records (EHRs), processes the data using Web-based clinical decision support algorithms, and displays the CDS output seamlessly on the EHR screen for use by the clinician and patient. Through a series of National Institutes of Health-funded projects led by HealthPartners Institute and the HealthPartners Center for Chronic Care Innovation and HCSRN partners, Priorities Wizard has been evaluated in cluster-randomized trials and expanded to include over 20 clinical domains.Results:Cluster-randomized trials show that this CDS system significantly improved glucose and blood pressure control in diabetes patients, reduced 10-year cardiovascular (CV) risk in high-CV risk adults without diabetes, improved management of smoking in dental patients, and improved high blood pressure identification and management in adolescents. CDS output was used at 71–77 percent of targeted visits, 85–98 percent of clinicians were satisfied with the CDS system, and 94 percent reported they would recommend it to colleagues.Conclusions:Recently developed EHR-linked, Web-based CDS systems have significantly improved chronic disease care outcomes and have high use rates and primary care clinician satisfaction.

The Promise of Pragmatic Clinical Trials Embedded in Learning Health Systems.

This commentary describes the need for a different context to clinical research that could speed the discovery and implementation of evidence-based advancements to health care delivery. Pragmatic clinical trials (PCTs) are a promising type of trial conducted within real-world health care delivery systems like organizations within the Health Care Systems Research Network, that embrace research as part of their culture of continuous learning and improvement. In these learning health systems (LHSs) clinical practice influences research and vice versa. A goal of LHSs is to operationalize evidence generated by research, particularly PCTs, into improvements that are sustained after a trial ends. PCTs that demonstrate value to health systems and foster implementation could reduce delays in translating research into practice.

Advancing Learning Health Systems Through Embedded Research: The 23rd Annual Conference of the Health Care Systems Research Network.

The 23rd annual conference of the Health Care Systems Research Network (HCSRN, formerly the HMO Research Network) was held in San Diego, California, March 21-23, 2017, attracting 387 attendees. As a consortium of 20 research organizations embedded in or affiliated with large health care delivery organizations, the HCSRN has held annual research conferences since 1994. The overall aim of the conferences is to bring researchers, project staff, research funders and other stakeholders together to share latest scientific findings and foster new research ideas and collaborations. The 2017 conference was hosted by the Palo Alto Medical Foundation Research Institute. Each host site takes responsibility for the content and structure of the conference, and the 2017 team introduced several new features. In particular, past conferences used concurrent sessions to present research results in different topical areas, such as chronic disease, cancer, health informatics, mental health or precision medicine. This year, concurrent sessions shifted to panel discussions about how research results were achieved, including the use of methods, partnerships and analytic approaches. The 35 panels were organized into tracks such as engagement, data and informatics, partnerships and research implementation. Scientific results from HCSRN projects were presented via 120 posters in two poster sessions. Plenary sessions included a town hall-style panel with different funding agency representatives, an opening presentation on the range of opportunities and benefits to studying health systems, and a concluding presentation on how researchers can apply design thinking in their work.
