Background The goal of this study was an assessment of availability postoperative pain management quality measures and National Quality Forum–endorsed measures. Postoperative pain is an important clinical timepoint because poor pain control can lead to patient suffering, chronic opiate use, and/or chronic pain. Quality measures can guide best practices, but it is unclear whether there are measures for managing pain after surgery. Methods The National Quality Forum Quality Positioning System, Agency for Healthcare Research and Quality Indicators, and Centers for Medicare and Medicaid Services Measures Inventory Tool databases were searched in November 2019. We conducted a systematic literature review to further identify quality measures in research publications, clinical practice guidelines, and gray literature for the period between March 11, 2015 and March 11, 2020. Results Our systematic review yielded 1,328 publications, of which 206 were pertinent. Nineteen pain management quality measures were identified from the quality measure databases, and 5 were endorsed by National Quality Forum. The National Quality Forum measures were not specific to postoperative pain management. Three of the non-endorsed measures were specific to postoperative pain. Conclusion The dearth of published postoperative pain management quality measures, especially National Quality Forum–endorsed measures, highlights the need for more rigorous evidence and widely endorsed postoperative pain quality measures to guide best practices.

OBJECTIVE To evaluate how variation in the way patient satisfaction feedback is delivered relates to physician well-being and perceptions of its impact on patient care, job satisfaction, and clinical decision making. PARTICIPANTS AND METHODS A cross-sectional electronic survey was sent to faculty physicians from a large academic medical center in March 29, 2019. Physicians reported their exposure to feedback (timing, performance relative to peers, or channel) and related perceptions. The Professional Fulfillment Index captured burnout and professional fulfillment. Associations between feedback characteristics and well-being or perceived impact were tested using analysis of variance or logistic regression adjusted for covariates. RESULTS Of 1016 survey respondents, 569 (56.0%) reported receiving patient satisfaction feedback. Among those receiving feedback, 303 (53.2%) did not believe that this feedback improved patient care. Compared with physicians who never received feedback, those who received any type of feedback had higher professional fulfillment scores (mean, 6.6±2.1 vs 6.3±2.0; P=.03) but also reported an unfavorable impact on clinical decision making (odds ratio [OR], 2.9; 95% CI, 1.8 to 4.7; P

Rationale & Objective Elicitation and documentation of patient preferences is at the core of shared decision making and is particularly important among patients with high anticipated mortality. The extent to which older patients with incident kidney failure undertake such discussions with their providers is unknown and its characterization was the focus of this study. Study Design Retrospective cohort study. Setting & Participants A random sample of veterans 67 years and older with incident kidney failure receiving care from the US Veterans Health Administration between 2005 and 2010. Exposures Demographic and facility characteristics, as well as predicted 6-month mortality risk after dialysis initiation and documentation of resuscitation preferences. Outcomes Documented discussions of dialysis treatment and supportive care. Analytical Approach We reviewed medical records over the 2 years before incident kidney failure and up to 1 year afterward to ascertain the frequency and timing of documented discussions about dialysis treatment, supportive care, and resuscitation. Logistic regression was used to identify factors associated with these documented discussions. Results The cohort of 821 veterans had a mean age of 80.9±7.2 years, and 37.2% had a predicted 6-month mortality risk>20% with dialysis. Documented discussions addressing dialysis treatment and resuscitation were present in 55.6% and 77.1% of patients, respectively. Those addressing supportive care were present in 32.4%. The frequency of documentation varied by mortality risk and whether the patient ultimately started dialysis. In adjusted analyses, the frequency and pattern of documentation were more strongly associated with geographic location and receipt of outpatient nephrology care than with patient demographic or clinical characteristics. Limitations Documentation may not fully reflect the quality and content of discussions, and generalizability to nonveteran patients is limited. Conclusions Among older veterans with incident kidney failure, discussions of dialysis treatment are decoupled from other aspects of advance care planning and are suboptimally documented, even among patients at high risk for mortality.

Context Signature informed consent (SIC) is a part of a Veterans Health Administration ethics initiative for patient education and shared decision making with long-term opioid therapy (LTOT). Historically, patients with cancer-related pain receiving LTOT are exempt from this process. Objectives Our objective is to understand patients' and providers' perspectives on using SIC for LTOT in patients with cancer-related pain. Methods Semistructured interviews with 20 opioid prescribers and 20 patients who were prescribed opioids at two large academically affiliated Veterans Health Administration Medical Centers. We used a combination of deductive and inductive approaches in content analysis to produce emergent themes. Results Potential advantages of SIC are that it can clarify and help patients comprehend LTOT risks and benefits, provide clear upfront boundaries and expectations, and involve the patient in shared decision making. Potential disadvantages of SIC include time delay to treatment, discouragement from recommended opioid use, and impaired trust in the patient-provider relationship. Providers and patients have misconceptions about the definition of SIC. Providers and patients question if SIC for LTOT is really informed consent. Providers and patients advocate for strategies to improve comprehension of SIC content. Providers had divergent perspectives on exemptions from SIC. Oncologists want SIC for LTOT to be tailored for patients with cancer. Conclusion Provider and patient interviews highlight various aspects about the advantages and disadvantages of requiring SIC for LTOT in cancer-related pain. Tailoring SIC for LTOT to be specific to cancer-related concerns and to have an appropriate literacy level are important considerations.

Objectives Court documents have proven that a manufacturer-orchestrated strategy tried to promote gabapentin by distorting evidence in randomized trials. Given this background, we aimed to assess whether implausibly large treatment effects for gabapentin and for a similar gabapentinoid, pregabalin may have been published. Study Design and Setting We identified meta-analyses on gabapentin or pregabalin on any outcome from Google Scholar, PubMed, and EMBASE. We explored excess of significance in meta-analyses and whether outlier studies with extreme results (differing >0.8 standard deviations from the summary effect of the meta-analysis) were scrutinized. Results All 10 evaluated meta-analyses showed statistically significant favorable findings. Heterogeneity I2 estimates exceeding 90% were noted in four meta-analyses of postoperative pain. In these four meta-analyses, 77 studies had estimates differing >0.8 standard deviations from the summary estimate. Thirty-nine of 77 represented extremely favorable results, and 33 of them came from less developed countries with no tradition of clinical research, 22 reported no information on funding, and 20 reported no conflicts of interest. Conversely, 27 of 38 studies with unfavorable results came from more developed countries. Conclusion Extremely favorable outlier studies in the meta-analyzed literature of gabapentin and pregabalin may be a footprint of bias in studies done in less developed countries.

Many integrated health systems and accountable care organizations have turned to intensive primary care programs to improve quality of care and reduce costs for high-need high-cost patients. How best to implement such programs remains an active area of discussion. In 2014, the Veterans Health Administration (VHA) implemented five distinct intensive primary care programs as part of a demonstration project that targeted Veterans at the highest risk for hospitalization. We found that programs evolved over time, eventually converging on the implementation of the following elements: 1) an interdisciplinary care team, 2) chronic disease management, 3) comprehensive patient assessment and evaluation, 4) care and case management, 5) transitional care support, 6) preventive home visits, 7) pharmaceutical services, 8) chronic disease self-management, 9) caregiver support services, 10) health coaching, and 11) advanced care planning. The teams also found that including social workers and mental health providers on the interdisciplinary teams was critical to effectively address psychosocial needs of these complex patients. Having a central implementation coordinator facilitated the convergence of these program features across diverse demonstration sites. In future iterations of these programs, VHA intends to standardize staffing and key features to develop a scalable program that can be disseminated throughout the system.

Objectives Cancer costs have increased substantially in the past decades, prompting specialty societies to urge oncologists to consider value in clinical decision making. Despite oncologists' crucial role in guiding cancer care, current literature is sparse with respect to the oncologists' views on value. Here, we evaluated oncologists perceptions of the use and measurement of value in cancer care. Methods We conducted in-depth, open-ended interviews with 31 US oncologists practicing nationwide in various environments. Oncologists discussed the definition, measurement, and implementation of value. Transcripts were analyzed using matrix and thematic analysis. Results Oncologists' definitions of value varied greatly. Some described versions of the standard health economic definition of value, that is, cost relative to health outcomes. Many others did not include cost in their definition of value. Oncologists considered patient goals and quality of life as important components of value that they perceived were missing from current value measurement. Oncologists prioritized a patient-centric view of value over societal or other perspectives. Oncologists were inclined to consider the value of a treatment only if they perceived treatment would pose a financial burden to patients. Oncologists had differing opinions regarding who should be responsible for determining whether care is low value but generally felt this should remain within the purview of the oncology community. Conclusions Oncologists agreed that cost was an important issue, but disagreed about whether cost was involved in value as well as the role of value in guiding treatment. Better clarity and alignment on the definition of and appropriate way to measure value is critical to the success of efforts to improve value in cancer care.

Background An emergency manual (EM) is a set of evidence-based crisis checklists, or cognitive aids, that can improve team performance. EMs are used in other safety-critical industries, and health care simulation studies have shown their efficacy, but use in clinical settings is nascent. A case study was conducted on the use of an EM during one intraoperative crisis, which entailed the assessment of the impact of the EM's use on teamwork and patient care and the identification of lessons for effectively using EMs during future clinical crises. Methods In a case study of a single crisis, an EM was used during a cardiac arrest at a tertiary care hospital that had systematically implemented perioperative EMs. Semistructured interviews were conducted with all six clinicians present, interview transcripts were iteratively coded, and thematic analysis was performed. Results All clinician participants stated that EM use enabled effective team functioning via reducing stress of individual clinicians, fostering a calm work environment, and improving teamwork and communication. These impacts in turn improved the delivery of patient care during a clinical crisis and influenced participants' intended EM use during future appropriate crises. Conclusion In this positive-exemplar case study, an EM was used to improve delivery of evidence-based patient care through effective clinical team functioning. EM use must complement rather than replace good clinician education, judgment, and teamwork. More broadly, understanding why and how things go well via analyzing positive-exemplar case studies, as a converse of root cause analyses for negative events, can be used to identify effective applications of safety innovations.

Objectives To determine whether implementation of interferon-free treatment for hepatitis C virus (HCV) reached groups less likely to benefit from earlier therapies, including patients with genotype 1 virus or contraindications to interferon treatment, and groups that faced treatment disparities: African Americans, patients with HIV co-infection, and those with drug use disorder. Methods Electronic medical records of the US Veterans Health Administration (VHA) were used to characterize patients with chronic HCV infection and the treatments they received. Initiation of treatment in 206,544 patients with chronic HCV characterized by viral genotype, demographic characteristics, and comorbid medical and mental illness was studied using a competing events Cox regression over 6 years. Results With the advent of interferon-free regimens, the proportion treated increased from 2.4% in 2010 to 18.1% in 2015, an absolute increase of 15.7%. Patients with genotype 1 virus, poor response to previous treatment, and liver disease had the greatest increase. Large absolute increases in the proportion treated were observed in patients with HIV co-infection (18.6%), alcohol use disorder (11.9%), and drug use disorder (12.6%) and in African American (13.7%) and Hispanic (13.5%) patients, groups that were less likely to receive interferon-containing treatment. The VHA spent $962 million on interferon-free treatments in 2015, 1.5% of its operating budget. Conclusions The proportion of patients with HCV treated in VHA increased sevenfold. The VHA was successful in implementing interferon treatment in previously undertreated populations, and this may become the community standard of care.

Background Patient-centered medical homes have made great strides providing comprehensive care for patients with chronic conditions, but may not provide sufficient support for patients at highest risk for acute care use. To address this, the Veterans Health Administration (VHA) initiated a five-site demonstration project to evaluate the effectiveness of augmenting the VA's Patient Aligned Care Team (PACT) medical home with PACT Intensive Management (PIM) teams for Veterans at highest risk for hospitalization. Methods/design Researchers partnered with VHA leadership to design a mixed-methods prospective multi-site evaluation that met leadership's desire for a rigorous evaluation conducted as quality improvement rather than research. We conducted a randomized QI evaluation and assigned high-risk patients to participate in PIM and compared them with high-risk Veterans receiving usual care through PACT. The summative evaluation examines whether PIM: 1) decreases VHA emergency department and hospital use; 2) increases satisfaction with VHA care; 3) decreases provider burnout; and 4) generates positive returns on investment. The formative evaluation aims to support improved care for high-risk patients at demonstration sites and to inform future initiatives for high-risk patients. The evaluation was reviewed by representatives from the VHA Office of Research and Development and the Office of Research Oversight and met criteria for quality improvement. Discussion VHA aims to function as a learning organization by rapidly implementing and rigorously testing QI innovations prior to final program or policy development. We observed challenges and opportunities in designing an evaluation consistent with QI standards and operations priorities, while also maintaining scientific rigor. Trial registration: This trial was retrospectively registered at ClinicalTrials.gov on April 3, 2017: NCT03100526 . Protocol v1, FY14-17.

Background Context Degenerative lumbar scoliosis (DLS) is often associated with sagittal imbalance, which may affect patients' health outcomes before and after surgery. The appropriateness of surgery and preferred operative approaches has not been examined in detail for patients with DLS and sagittal imbalance. Purpose The goals of this article were to describe what is currently known about the relationship between sagittal imbalance and health outcomes among patients with DLS and to determine how indications for surgery in patients with DLS differ when sagittal imbalance is present. Study Design/Setting This study included a literature review and an expert panel using the RAND/University of California at Los Angeles (UCLA) Appropriateness Method. Methods To develop appropriate use criteria for DLS, researchers at the RAND Corporation recently employed the RAND/UCLA Appropriateness Method, which involves a systematic review of the literature and multidisciplinary expert panel process. Experts reviewed a synopsis of published literature and rated the appropriateness of five common operative approaches for 260 different clinical scenarios. In the present work, we updated the literature review and compared panelists' ratings in scenarios where imbalance was present versus absent. This work was funded by the Collaborative Spine Research Foundation, a group of surgical specialty societies and device manufacturers. Results On the basis of 13 eligible studies that examined sagittal imbalance and outcomes in patients with DLS, imbalance was associated with worse functional status in the absence of surgery and worse symptoms and complications postoperatively. Panelists' ratings demonstrated a consistent pattern across the diverse clinical scenarios. In general, when imbalance was present, surgery was more likely to be appropriate or necessary, including in some situations where surgery would otherwise be inappropriate. For patients with moderate to severe symptoms and imbalance, a deformity correction procedure was usually appropriate and frequently necessary, except in some patients with severe risk factors for complications. Conversely, procedures that did not correct imbalance, when present, were usually inappropriate. Conclusions Clinical experts agreed that sagittal imbalance is a major factor affecting both when surgery is appropriate and which type of procedure is preferred among patients with DLS.

Background Clinical practice guidelines recommend referral to nephrology when estimated glomerular filtration rate (eGFR) decreases to 2 ; however, evidence for benefits of nephrology care are mixed. Study Design Observational cohort using landmark analysis. Settings & Participants A national cohort of veterans with advanced chronic kidney disease, defined as an outpatient eGFR≤30mL/min/1.73m 2 for January 1, 2010, through December 31, 2010, and a prior eGFR 2 , using administrative and laboratory data from the Department of Veterans Affairs and the US Renal Data System. Predictor Receipt and frequency of outpatient nephrology care over 12 months. Outcomes Survival and progression to end-stage renal disease (ESRD; receipt of dialysis or kidney transplantation) were the primary outcomes. In addition, control of associated clinical parameters over 12 months were intermediate outcomes. Results Of 39,669 patients included in the cohort, 14,983 (37.8%) received nephrology care. Older age, heart failure, dementia, depression, and rapidly declining kidney function were independently associated with the absence of nephrology care. During a mean follow-up of 2.9 years, 14,719 (37.1%) patients died and 4,310 (10.9%) progressed to ESRD. In models adjusting for demographics, comorbid conditions, and trajectory of kidney function, nephrology care was associated with lower risk for death (HR, 0.88; 95% CI, 0.85-0.91), but higher risk for ESRD (HR, 1.48; 95% CI, 1.38-1.58). Among patients with clinical parameters outside guideline recommendations at cohort entry, a significantly higher adjusted proportion of patients who received nephrology care had improvement in control of hemoglobin, potassium, albumin, calcium, and phosphorus concentrations compared with those who did not receive nephrology care. Limitations May not be generalizable to nonveterans. Conclusions Among patients with advanced chronic kidney disease, nephrology care was associated with lower mortality, but was not associated with lower risk for progression to ESRD.

Objective Determine how varying longitudinal historical training data can impact prediction of future clinical decisions. Estimate the " decay rate " of clinical data source relevance. Materials and methods We trained a clinical order recommender system, analogous to Netflix or Amazon's " Customers who bought A also bought B... " product recommenders, based on a tertiary academic hospital's structured electronic health record data. We used this system to predict future (2013) admission orders based on different subsets of historical training data (2009 through 2012), relative to existing human-authored order sets. Results Predicting future (2013) inpatient orders is more accurate with models trained on just one month of recent (2012) data than with 12 months of older (2009) data (ROC AUC 0.91 vs. 0.88, precision 27% vs. 22%, recall 52% vs. 43%, all P −10 ). Algorithmically learned models from even the older (2009) data was still more effective than existing human-authored order sets (ROC AUC 0.81, precision 16% recall 35%). Training with more longitudinal data (2009–2012) was no better than using only the most recent (2012) data, unless applying a decaying weighting scheme with a " half-life " of data relevance about 4 months. Discussion Clinical practice patterns (automatically) learned from electronic health record data can vary substantially across years. Gold standards for clinical decision support are elusive moving targets, reinforcing the need for automated methods that can adapt to evolving information. Conclusions and relevancm Prioritizing small amounts of recent data is more effective than using larger amounts of older data towards future clinical predictions.

In order to enhance care for high-risk patients, many health systems are implementing intensive outpatient programs, often with advanced practice nurses taking the lead. We sought to examine the effects of 1 such nurse practitioner−led program on end-of-life care for patients in the Veterans Affairs health care system. Patients enrolled in the intensive program had higher rates of hospice referral (74%) compared with patients enrolled in standard primary care (44%) (P = .025). Nurse practitioner−led intensive outpatient primary care may increase hospice referrals for high-risk patients near end-of-life.

Graphical abstract, Background Unlike well-established diseases that base clinical care on randomized trials, past experiences, and training, prognosis in COVID19 relies on a weaker foundation. Knowledge from other respiratory failure diseases may inform clinical decisions in this novel disease. The objective was to predict 48-hour invasive mechanical ventilation (IMV) within 48 h in patients hospitalized with COVID-19 using COVID-like diseases (CLD). Methods This retrospective multicenter study trained machine learning (ML) models on patients hospitalized with CLD to predict IMV within 48 h in COVID-19 patients. CLD patients were identified using diagnosis codes for bacterial pneumonia, viral pneumonia, influenza, unspecified pneumonia and acute respiratory distress syndrome (ARDS), 2008–2019. A total of 16 cohorts were constructed, including any combinations of the four diseases plus an exploratory ARDS cohort, to determine the most appropriate cohort to use. Candidate predictors included demographic and clinical parameters that were previously associated with poor COVID-19 outcomes. Model development included the implementation of logistic regression and three ensemble tree-based algorithms: decision tree, AdaBoost, and XGBoost. Models were validated in hospitalized COVID-19 patients at two healthcare systems, March 2020–July 2020. ML models were trained on CLD patients at Stanford Hospital Alliance (SHA). Models were validated on hospitalized COVID-19 patients at both SHA and Intermountain Healthcare. Results CLD training data were obtained from SHA (n = 14,030), and validation data included 444 adult COVID-19 hospitalized patients from SHA (n = 185) and Intermountain (n = 259). XGBoost was the top-performing ML model, and among the 16 CLD training cohorts, the best model achieved an area under curve (AUC) of 0.883 in the validation set. In COVID-19 patients, the prediction models exhibited moderate discrimination performance, with the best models achieving an AUC of 0.77 at SHA and 0.65 at Intermountain. The model trained on all pneumonia and influenza cohorts had the best overall performance (SHA: positive predictive value (PPV) 0.29, negative predictive value (NPV) 0.97, positive likelihood ratio (PLR) 10.7; Intermountain: PPV, 0.23, NPV 0.97, PLR 10.3). We identified important factors associated with IMV that are not traditionally considered for respiratory diseases. Conclusions The performance of prediction models derived from CLD for 48-hour IMV in patients hospitalized with COVID-19 demonstrate high specificity and can be used as a triage tool at point of care. Novel predictors of IMV identified in COVID-19 are often overlooked in clinical practice. Lessons learned from our approach may assist other research institutes seeking to build artificial intelligence technologies for novel or rare diseases with limited data for training and validation.

In 2008, the Veterans Health Administration published a groundbreaking policy on disclosing large-scale adverse events to patients in order to promote transparent communication in cases where harm may not be obvious or even certain. Without embedded research, the evidence on whether or not implementation of this policy was generating more harm than good among Veteran patients was unknown. Through an embedded research-operations partnership, we conducted four research projects that led to the development of an evidence-based large-scale disclosure toolkit and disclosure support program, and its implementation across VA healthcare. Guided by the Consolidated Framework for Implementation Research, we identified specific activities corresponding to planning, engaging, executing, reflecting and evaluating phases in the process of implementation. These activities included planning with operational leaders to establish a shared research agenda; engaging with stakeholders to discuss early results, establishing buy-in of our efforts and receiving feedback; joining existing operational teams to execute the toolkit implementation; partnering with clinical operations to evaluate the toolkit during real-time disclosures; and redesigning the toolkit to meet stakeholders' needs. Critical lessons learned for implementation success included a need for stakeholder collaboration and engagement, an organizational culture involving a strong belief in evidence, a willingness to embed researchers in clinical operation activities, allowing for testing and evaluation of innovative practices, and researchers open to constructive feedback. At the conclusion of the research, VA operations worked with the researchers to continue to support efforts to spread, scale-up and sustain toolkit use across the VA healthcare system, with the final goal to establish long-term sustainability.

Background Collaboration between researchers, implementers and policymakers improves uptake of health systems research. In 2018, researchers and VHA Innovators Network (iNET) leadership used an embedded research model to conduct an evaluation of iNET. We describe our evaluation design, early results, and lessons learned. Methods This mixed-methods evaluation incorporated primary data collection via electronic survey , descriptive analysis using existing VA datasets (examining associations between facility characteristics and iNET participation), and qualitative interviews to support real-time program implementation and to probe perceived impacts, benefits and challenges of participation. Results We developed reporting tools and collected data regarding site participation, providing iNET leadership rapid access to needed information on projects (e.g., target populations reached, milestones achieved, and barriers encountered). Secondary data analyses indicated iNET membership was greater among larger, more complex VA facilities. Of the 37 iNET member sites, over half (n = 22) did not have any of the six major types of VA research centers; thus iNET is supporting VA sites not traditionally served by research innovation pathways. Qualitative findings highlighted enhanced engagement and perceived value of social and informational networks. Conclusions Working alongside our iNET partners, we supported and influenced iNET's development through our embedded evaluation's preliminary findings. We also provided training and guidance aimed at building capacity among iNET participants. Implications Embedded research can yield successful collaborative efforts between researchers and partners. An embedded research team can help programs pivot to ensure effective use of limited resources. Such models inform program development and expansion, supporting strategic planning and demonstrating value.

Objectives We examined print, broadcast and social media reports about health care systems' disclosures of large scale adverse events to develop future effective messaging. Study design Directed content analysis. Methods We systematically searched four communication databases, YouTube and Really Simple Syndication (RSS) feeds relating to six disclosures of lapses in infection control practices in the Department of Veterans Affairs occurring between 2009 and 2012. We assessed these with a coding frame derived from effective crisis and risk communication models. Results We identified 148 unique media reports. Some components of effective communication (discussion of cause, reassurance, self-efficacy) were more present than others (apology, lessons learned). Media about ‘promoting secrecy’ and ‘slow response’ appeared in reports when time from event discovery to patient notification was over 75 days. Elected officials' quotes (n = 115) were often negative (83%). Hospital officials' comments (n = 165) were predominantly neutral (92%), and focused on information sharing. Conclusions Health care systems should work to ensure that they develop clear messages focused on what is not well covered by the media, including authentic apologies, remedial actions taken, and shorten the timeframe between event identification and disclosure to patients.

Like all facets of healthcare practice, quality improvement (QI) should be conducted in an ethically responsible manner. For methodologically complex QI, accountability and thoughtful ethical monitoring might be particularly important. Yet, access to ethical guidance for QI, as opposed to research, is often limited. Available mechanisms tend to be ill-equipped to accommodate the rapid cycle nature of QI, and monitoring standards for QI are not well defined. Providing appropriate ethical guidance for complex, multi-site QI initiatives can be especially challenging, as the body providing guidance must be familiar with QI methods, recognize the competing interests of stakeholder groups, respond to numerous requests, and understand the initiative's design. This case report describes our solution-an initiative-specific QI Ethics Committee that provided ethical guidance and consultation to a Veterans Administration QI initiative employing local innovations and a centralized evaluation. Enhanced by multiple tables, we discuss structuring and staffing the committee, the committee's role, functions and activities, requests for ethics guidance, and our strategy applying initiative-specific ethical principles to guide recommendations. Supported by feedback obtained from stakeholder interviews, we share key insights regarding the value of: • Clarifying and marketing the committee's role to users. • Reconciling conflicting interests between site-based team members and cross-site evaluators. • Separating ethics guidance from regulatory oversight. • Addressing the ethics of evaluative design. • Adjusting the intensity of the committee's work over time. • Creating tangible products. Our approach shows promise in supporting the ethical practice of methodologically complex QI, especially in institutions that lack applicable ethics monitoring mechanisms. Building on this approach, other complex QI initiatives can develop effective and feasible methods to protect participants from unintentional ethical lapses.

Background & Aims The Veterans Health Administration (VHA) is the largest single provider of care for hepatitis C virus (HCV) infection in the United States. We analyzed the cost effectiveness of treatment with the HCV protease inhibitors boceprevir and telaprevir in a defined managed care population of 102,851 patients with untreated chronic genotype 1 infection. Methods We used a decision-analytic Markov model to examine 4 strategies: standard dual-therapy with pegylated interferon-alfa and ribavirin (PR), the combination of boceprevir and PR triple therapy, the combination of telaprevir and PR, or no antiviral treatment. A sensitivity analysis was performed. Sources of data included published rates of disease progression, the census bureau, and VHA pharmacy and hospitalization cost databases. Results The estimated costs for treating each patient were $8000 for PR, $31,300 for boceprevir and PR, and $41,700 for telaprevir and PR. Assuming VHA treatment rates of 22% and optimal rates of sustained virologic response, PR, boceprevir and PR, and telaprevir and PR would reduce relative liver-related deaths by 5.2%, 10.9%, and 11.5%, respectively. Increasing treatment rates to 50% would reduce liver-related deaths by 12%, 24.7%, and 26.1%, respectively. The incremental cost-effectiveness ratios were $29,184/quality-adjusted life-years for boceprevir and PR and $44,247/quality-adjusted life-years for telaprevir and PR vs only PR. With the current 22% treatment rate, total system-wide costs to adopt boceprevir and PR or telaprevir and PR would range from $708 to $943 million. Conclusions Despite substantial up-front costs of treating HCV-infected patients in the VHA with PR, or telaprevir and PR, each regimen improves quality of life and extends life expectancy by reducing liver-related morbidity and mortality, and should be cost effective. Further efforts to expand access to direct-acting antiviral therapy are warranted.

Objectives: The long-term cost effectiveness of routine HIV testing is favorable relative to other medical interventions. Facility-specific costs of expanded HIV testing and care for newly identified patients, however, are less well defined. To aid in resource allocation decisions, we developed a spreadsheet-based budget-impact tool populated with estimates of facility-specific HIV testing and care costs incurred with an expanded testing program. Methods: We modeled intervention effects on quarterly costs of antiretroviral therapy (ART), outpatient resource utilization, and staff expenditures in the Department of Veterans Affairs over a 2-year period of increasing HIV testing rates. We used HIV prevalence estimates, screening rates, counseling, positive tests, Veterans Affairs treatment, and published sources as inputs. We evaluated a single-facility cohort of 20,000 patients and at baseline assumed a serodiagnostic rate of 0.45%. Results: Expanding testing from 2% to 15% annually identified 21 additional HIV-positive patients over 2 years at a cost of approximately $290,000, more than 60% of which was due to providing ART to newly diagnosed patients. While quarterly testing costs decreased longitudinally as fewer persons required testing, quarterly ART costs increased from $10,000 to more than $60,000 over 2 years as more infected patients were identified and started on ART. In sensitivity analyses, serodiagnostic and annual HIV testing rates had the greatest cost impact. Conclusions: Expanded HIV testing costs are greatest during initial implementation and predominantly due to ART for new patients. Cost determinations of expanded HIV testing provide an important tool for managers charged with allocating resources within integrated systems providing both HIV testing and care.

Background & Aims Ascites are the most common complication of cirrhosis. Evidence-based guidelines define the criteria and standards of care for patients with cirrhosis and ascites. However, little is known about the extent to which patients with ascites meet these standards. Methods We evaluated the quality of ascites care, measured by 8 explicit Delphi panel–derived quality indicators, in 774 patients with cirrhosis and ascites, seen at 3 Veterans Affairs Medical Centers between 2000 and 2007. We also conducted a structured implicit review of patients' medical charts to determine whether patient refusal, outside care, or other justifiable exceptions to care processes account for nonadherence to the quality indicators. Results Quality scores (maximum 100%) varied among individual indicators, ranging from 30% for secondary prophylaxis of spontaneous bacterial peritonitis, to 90% for assays for cell number and type in the paracentesis fluid. In general, care targeted at treatment was more likely to meet standards than preventive care. Only 33.2% (95% confidence interval [CI]: 29.9%−32.9%) of patients received all recommended care. Patients with no comorbidity (Deyo index 0 vs >3; odds ratio=2.21; 95% CI: 1.43−3.43), who saw a gastroenterologist (odds ratio=1.33; 95% CI, 1.01−1.74), or were seen in a facility with academic affiliation (odds ratio=1.73; 95% CI: 1.29−2.35) received higher-quality care. Justifiable exceptions to indicated care, documented in charts, were common for patients with paracentesis after diagnosis with ascites, patients that received antibiotics for gastrointestinal bleeding, and patients that required diuretics. However, most patients did not have an explanation documented for nonadherence to recommended care. Conclusions Health care quality, measured by whether patients received recommended services, was suboptimal for patients with cirrhosis-related ascites. Care that included gastroenterologists was associated with high quality. However, for some of the quality indicators, too many denominator exceptions existed to allow for accurate automated measurement.

Efforts to promote awareness and management of chronic pain have been accompanied by a troubling increase in prescription medication abuse. At the same time, some patients may misuse substances in an effort to manage chronic pain.This study examines self-reported substance misuse for pain management among veterans and identifies the contributing factors.We analyzed cross-sectional data from the Help Veterans Experience Less Pain study.Of 343 veterans, 35.3% reported an aberrant pain management behavior (24% reported using alcohol, 11.7% reported using street drugs, and 16.3% reported sharing prescriptions to manage pain). Poorer mental health, younger age, substance use disorders (SUDs), number of nonpain symptoms, and greater pain severity and interference were associated with aberrant pain management behaviors. In multivariate analysis, SUDs (odds ratio [OR]: 3.9, 95% confidence interval [CI]: 2.3-6.7, P0.000) and poorer mental health (OR: 2.3, 95% CI: 1.3-4.3, P=0.006) were associated with using alcohol or street drugs to manage pain; SUDs (OR: 2.4, 95% CI: 1.3-4.4, P=0.006) and pain interference (OR: 1.1, 95% CI: 1.0-1.2, P=0.047) were associated with prescription sharing; and SUDs (OR: 3.6, 95% CI: 2.2-6.1, P0.000) and number of nonpain symptoms (OR: 6.5, 95% CI: 1.2-35.4, P=0.031) were associated with any aberrant pain management behavior.Veterans with a history of SUDs, greater pain interference, more nonpain symptoms, and mental health concerns should be carefully managed to deter substance misuse for pain management.

Background & Aims There are limited data on the risk of hepatocellular cancer (HCC) in patients with non-alcoholic fatty liver disease (NAFLD). We aimed to estimate the risk of incident HCC among patients with NAFLD. Methods We conducted a retrospective cohort study from a total of 130 facilities in the Veterans Health Administration. Patients with NAFLD diagnosed between January 1, 2004 and December 31, 2008 were included and followed until HCC diagnosis, death, or December 31, 2015. We also identified a sex- and age-matched control cohort without NAFLD. We ascertained all new HCC cases from the Central Cancer Registry and manual chart reviews. We calculated incidence rates for HCC by NAFLD status, as well as in subgroups of NAFLD patients. We used competing risk models to compare the risk of HCC in patients with NAFLD vs those without NAFLD. We reviewed electronic medical records of all HCC cases that developed in NAFLD patients without cirrhosis. Results We compared 296,707 NAFLD patients with 296,707 matched controls. During 2,382,289 person-years [PYs] of follow-up, 490 NAFLD patients developed HCC (0.21/1000 PYs). HCC incidence was significantly higher among NAFLD patients vs controls (0.02/1000 PYs; hazard ratio, 7.62; 95% confidence interval, 5.76–10.09). Among patients with NAFLD, those with cirrhosis had the highest annual incidence of HCC (10.6/1000 PYs). Among patients with NAFLD cirrhosis, HCC risk ranged from 1.6 to 23.7 per 1000 PYs based on other demographic characteristics; risk of HCC was the highest in older Hispanics with cirrhosis. In medical record reviews, 20% of NAFLD patients with HCC had no evidence of cirrhosis. Conclusions Risk of HCC was higher in NAFLD patients than that observed in general clinical population. Most HCC cases in NAFLD developed in patients with cirrhosis. The absolute risk of HCC was higher than the accepted thresholds for HCC surveillance for most patients with NAFLD cirrhosis.

Background & Aims Cirrhosis is a prevalent and expensive condition. With an increasing emphasis on quality in health care and recognition of inconsistencies in the management of patients with cirrhosis, we established a set of explicit quality indicators (QIs) for their treatment. Methods We organized an 11-member, multidisciplinary expert panel and followed modified Delphi methods to systematically identify a set of QIs for cirrhosis. We provided the panel with a report that summarized the results of a comprehensive literature review of data linking candidate QIs to outcomes. The panel performed independent ratings of each candidate QI by using a standard 9-point RAND appropriateness scale (RAS) (ranging from 1=not appropriate to 9=most appropriate). The panel members then met, reviewed the ratings, and voted again by using an iterative process of discussion. The final set of QIs was selected; QIs had a median RAS >7, and panel members agreed on those selected. Results Among 169 candidate QIs, the panel rated 41 QIs as valid measures of quality care. The selected QIs cover 6 domains of care including ascites (13 QIs), variceal bleeding (18 QIs), hepatic encephalopathy (4 QIs), hepatocellular cancer (1 QI), liver transplantation (2 QIs), and general cirrhosis care (3 QIs). Content coverage included prevention, diagnosis, treatment, timeliness, and follow-up. Conclusions We developed an explicit set of evidence-based QIs for treatment of cirrhosis. These provide physicians and institutions with a tool to identify processes amenable to quality improvement. This tool is intended to be applicable in any setting where care for patients with cirrhosis is provided.

Syncope is a common reason for emergency department (ED) visits, and patients are often admitted to exclude syncope of cardiovascular origin. Population-based data on patterns and predictors of cardiac outcomes may improve decision-making. Our objective was to identify patterns and predictors of short-term cardiac outcomes in ED patients with syncope. Administrative data from an integrated health system of 11 Southern California EDs were used to identify cardiac outcomes after ED presentation for syncope from January 1, 2002, to December 31, 2005. Syncope and cause of death were identified by codes from the International Classification of Disease, Ninth Revision. Cardiac outcomes included cardiac death and hospitalization or procedure consistent with ischemic heart disease, valvular disease, or arrhythmia. Predictors of cardiac outcomes were identified through multivariate logistic regression. There were 35,330 adult subjects who accounted for 39,943 ED visits for syncope. Risk of cardiac outcome sharply decreased following the 7 days after syncope. A 7-day cardiac outcome occurred in 893 cases (3%). Positive predictors of 7-day cardiac outcomes included age > or =60 years, male gender, congestive heart failure, ischemic heart disease, cardiac arrhythmia, and valvular heart disease. Negative predictors included dementia, pacemaker, coronary revascularization, and cerebrovascular disease. There was an age-dependent relation between 7-day cardiac outcomes and arrhythmia and valvular disease, with younger patients (

Background Culturally targeted, informal social networking approaches to improving disaster preparedness have not been empirically tested. Purpose In partnership with community health promoters and the Los Angeles County Department of Public Health, this study tested a disaster preparedness program for Latino households. Design This study had a community-based, randomized, longitudinal cohort design with two groups and was conducted during February–October 2007. Assessments were made at baseline and 3 months. Analyses were carried out January–October 2008. Settings/participants Community-based study of 231 Latinos living in Los Angeles County. Intervention Participants were randomly assigned to attending platicas (small-group discussions led by a health promoter/ promotora de salud ) or receiving “media” (a culturally tailored mailer). A total of 187 (81.0%) completed the 3-month follow-up. Main outcome measure A self-reported disaster preparedness checklist was used. Results Among participants who did not have emergency water pre-intervention, 93.3% of those in the platica arm had it at follow-up, compared to 66.7% in the media arm ( p =0.003). Among participants who did not have food pre-intervention, 91.7% in the platica arm reported it at follow-up, compared to 60.6% in the media arm ( p =0.013). Finally, among participants who did not have a family communication plan pre-intervention, 70.4% in the platica arm reported one at follow-up, compared to 42.3% in the media arm ( p =0.002). Conclusions Although both arms improved in stockpiling water and food and creating a communication plan, the platica arm showed greater improvement than the media group.

Calls for screening for HIV infection among individuals with substance use disorders, including alcohol use, are increasing. We investigated HIV screening and its predictors in the Veterans Health Administration (VA) system among such individuals in care. Our primary outcome was retrospective evidence of screening for HIV infection, adjusting for patient demographics and important comorbid disease. Of the 371,749 sample patients with histories of substance use disorders using VA services, 20% had evidence of HIV screening. Screening was lowest among those with alcohol use disorders alone (11%) and highest among those treated in substance use programs (28%) or receiving inpatient care (28%). The findings suggest a low recognition of substance use disorders (especially alcohol use) as risk factors for HIV. Quality improvement initiatives to increase risk factor recognition and screening among patients with substance use disorders will yield benefits in the fight against HIV.

Patients and physicians often cite symptom control as one of their most important goals in cancer care. Despite this, a previous systematic review found few tools for evaluating the quality of supportive cancer management. We developed a comprehensive set of quality indicators for evaluating pain and nonpain symptom management as well as care planning needs in cancer patients. Based on the prevalence and quality-of-life data, clinician-researchers prioritized pain, psychosocial distress, dyspnea, nausea and vomiting, fatigue and anorexia, treatment-associated toxicities, and information and care planning for quality-indicator development. Using search terms and selection criteria, we identified English-language documents from Medline (1997-2007) and Internet-based searches. Based on this evidence, clinician-reviewers proposed process quality indicators. We then used the VA Health Services Research and Development (VA HSR & D) appropriateness methods to compile the ratings of a multidisciplinary, international expert panel of the validity and feasibility of each indicator. The panel judged 92 out of 133 (69%) proposed quality indicators valid and feasible (15 out of 23 pain, 5 out of 6 depression, 8 out of 11 dyspnea, 15 out of 19 nausea and vomiting, 13 out of 26 fatigue and anorexia, 23 out of 32 other treatment-associated toxicities, and 13 out of 16 information and care planning). Of the final indicators, 67 are potentially useful for inpatient and 81 for outpatient evaluation, and 26 address screening, 12 diagnostic evaluation, 20 management, and 21 follow-up. These quality indicators provide evidence-explicit tools for measuring processes critical to ensuring high-quality supportive cancer care. Research is needed to characterize adherence to recommended practices and to evaluate the use of these measures in quality improvement efforts.

Background Chronic hepatitis C virus (HCV) infection affects approximately 1.3% of the U.S. population. As up to 30% of HCV-antibody (anti-HCV)–positive patients have negative HCV ribonucleic acid (RNA), indicating resolution of infection, VA (Veterans Affairs) guidelines recommend RNA testing on all anti-HCV–positive patients. As HCV RNA testing is a prequel to treatment, perceived eligibility for treatment may influence the decision to order an RNA test. This study was designed to determine the patient and healthcare facility factors associated with patient receipt of HCV RNA testing. Methods Two logistic regression analyses were conducted in anti-HCV–positive patients, including the entire sample and then on a subsample excluding sites with routine HCV RNA testing policies, using data stored in the VA Southern California Network data warehouse. Significant patient- and site-level predictors of patient receipt of HCV RNA testing were determined. Results Of the 13,257 antibody-positive patients, 76% received HCV RNA testing. Excluding sites with routine HCV RNA testing, patients aged >65 years (RR=0.79) and illicit drug users (RR=0.94) were significantly less likely to receive HCV RNA testing. Patients with abnormal transaminases (RR=1.14), presence of non-HCV hepatitis (RR=1.08), or decompensated liver disease (RR=1.22) were significantly more likely to receive HCV RNA testing. Conclusions Without policies for routine RNA testing, patients with hepatitic C who either are aged >65 years or are illicit drug users are less likely to be tested. Also, patient receipt of RNA testing becomes dependent on clinical cues of hepatic decompensation or inflammation. The results support the implementation of routine RNA testing for anti-HCV–positive patients.

Chan L, Ciol MA, Shumway-Cook A, Yorkston KM, Dudgeon BJ, Asch SM, Hoffman JM. A longitudinal evaluation of persons with disabilities: does a longitudinal definition help define who receives necessary care? Objective To assess, using a longitudinal definition, the impact of disability on a broad range of objective health care quality indicators. Design Longitudinal cohort study following up with patients over several years. The first 2 interviews, 1 year apart, were used to determine each patient's disability status in activities of daily living (ADLs). Assessment of the health care indicators commenced after the second interview and continued throughout the survey period (an additional 1–3y). Setting National survey. Participants Participants (N=29,074) of the Medicare Current Beneficiary Survey (1992–2001) with no, increasing, decreasing, and stable ADL disability. Interventions Not applicable. Main Outcome Measure The incidence of 5 avoidable outcomes, receipt of 3 preventive care measures, and adherence to 32 diagnostically based indicators assessing the quality of treatment for acute myocardial infarction [AMI], angina, breast cancer, cerebrovascular accident, transient ischemic attack, cholelithiasis, chronic obstructive pulmonary disease [COPD], congestive heart failure, depression, gastrointestinal bleeding, diabetes, and hypertension. Results For most indicators, less than 75% of eligible patients received necessary care, regardless of disability status. For 5 indicators, less than 50% of patients received appropriate treatment. In a logistic regression analysis that controlled for patient age, sex, race, and income, disability status was a significant factor in 7 quality measures (AMI, breast cancer, COPD, diabetes, angina, pneumonia, annual visits). Conclusions Using a longitudinal definition of disability and objective health quality indicators, we found that disability status can be an important factor in determining receipt of quality health care in a broad range of diagnostic categories. However, the impact of disability status varies depending on the indicator measured. In this cohort of patients, the changing nature of a person's disability seems to have less impact than whether they ever have had any functional deficits.

We described the availability and outcomes of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) testing services at syringe exchange programs throughout California, using interviews with 24 syringe exchange program directors and 560 syringe exchange clients. Both HIV and HCV testing services were available in 62% of programs, 21% had HIV testing only, and 17% had neither. Programs administered by health care/social service providers were more likely than independent syringe exchange programs to have HIV and HCV testing services available. Among clients of programs with testing available, clients of illegal programs were significantly less likely than clients of legal programs to have used syringe exchange HIV and HCV testing services. The availability of HIV and HCV testing services at syringe exchange programs varies, and the use of existing testing services by clients is not universal. Efforts to increase both the availability of HIV and HCV testing services at syringe exchange programs and the use of existing testing services are needed.

Background Residents in poor neighborhoods have higher body mass index (BMI) and eat less healthfully. One possible reason might be the quality of available foods in their area. Location of grocery stores where individuals shop and its association with BMI were examined. Methods The 2000 U.S. Census data were linked with the Los Angeles Family and Neighborhood Study (L.A.FANS) database, which consists of 2620 adults sampled from 65 neighborhoods in Los Angeles County between 2000 and 2002. In 2005, multilevel linear regressions were used to estimate the associations between BMI and socioeconomic characteristics of grocery store locations after adjustment for individual-level factors and socioeconomic characteristics of residential neighborhoods. Results Individuals have higher BMI if they reside in disadvantaged areas and in areas where the average person frequents grocery stores located in more disadvantaged neighborhoods. Those who own cars and travel farther to their grocery stores also have higher BMI. When controlling for grocery store census tract socioeconomic status (SES), the association between residential census tract SES and BMI becomes stronger. Conclusions Where people shop for groceries and distance traveled to grocery stores are independently associated with BMI. Exposure to grocery store mediates and suppresses the association of residential neighborhoods with BMI and could explain why previous studies may not have found robust associations between residential neighborhood predictors and BMI.

Background Comprehensive preventive services are recommended for injection drug users (IDU), including screening tests, vaccinations, risk reduction counseling, and sterile syringes. Syringe exchange programs (SEP) may facilitate receipt of preventive services by IDUs, but whether SEP clients receive recommended preventive care is not known. We examined use of recommended preventive services by clients of 23 SEPs throughout California. Methods Five hundred and sixty SEP clients were recruited from 23 SEPs throughout California between March and September 2003. Receipt of 10 recommended preventive services and source of care (SEP versus non-SEP providers) was ascertained from client interviews. Results On average, SEP clients received only 13% of recommended preventive services and 49% of clients received none of the recommended services. Of services that were received, 76% were received from SEPs. In multivariate analysis, use of drug treatment and more frequent SEP visits were associated with receipt of recommended preventive services by clients. Conclusions SEPs are often the only source of preventive care for their IDU clients. Still, SEP clients fail to receive most recommended preventive services. Interventions to increase use of preventive services and improve the quality of preventive care received by IDUs, such as increased access to drug treatment and SEPs, are needed.

The objective of this study was to determine whether participation in a quality improvement (QI) collaborative for heart failure (HF) was associated with better interpersonal aspects of care and health outcomes.We conducted a cross-sectional telephone survey of patients in 6 organizations who participated in a QI collaborative for HF (participants, n = 387) and 6 comparable control organizations (controls, n = 414) and measured provider-patient communication, education received, knowledge of HF, self-management behaviors, satisfaction, and quality of life. The participant group patients were more likely to report their doctor and nurse discussed treatment options and reviewed self-management (P.01 for both). A total of 88% of participants were told to weigh themselves daily and record their weight compared with 34% of controls (P.01). Participants were more likely to know how often to check their weight (P.01), recognize symptoms of worsening HF (Por = .01 for all), have a scale (P = .002), and monitor their weight daily (P.001). Participants had similar quality of life but fewer emergency department visits and hospitalizations.Participation in a QI collaborative for HF was associated with better communication, education, and knowledge, and lower health care use. Collaboratives may be a useful method for disseminating quality improvement strategies.

Advances in electronic medical record capabilities enable clinical reminders to inform providers when recommended actions are “due” for a patient. Despite evidence that they improve adherence to guidelines, the Veteran’s Health Administration (VHA) has experienced challenges in having providers consistently use clinical reminders as intended. In this paper, we describe how multiple methods were used to opportunistically triangulate, or “bootstrap,” an understanding of barriers to the effective use of clinical reminders in the VHA. In an initial study using ethnographic observations and semi-structured interviews of HIV clinical reminders, we identified six barriers to effective use: workload, time to remove inapplicable reminders, false alarms, training, reduced eye contact, and the use of paper forms rather than software. In a second study, we collected open-ended and closed-ended data regarding barriers and facilitators to the use of clinical reminders in general in the VHA through a survey of 261 participants at a national informatics meeting, where 104 of 142 VHA health care facilities were represented. The findings from the second study extended our understanding of the previously identified barriers. In addition, four new barriers were identified: ease of use issues, accessibility of workstations, resident physicians and trainees, and administration benefiting more than providers from clinical reminder use. We discuss potential implications regarding the similarities and differences in study findings for factors to consider in planning interventions to improve clinical reminder use.

Purpose To examine racial and ethnic differences in patients' preferences for initial care by specialists, and to determine whether trust in the physician and health beliefs account for these differences. Methods We conducted a cross-sectional study of 646 patients in the waiting room of three academic-based internal medicine outpatient practices. We asked subjects about their preference to see their primary care provider or a specialist first regarding the actual health problem that had brought them to see their physician as well as regarding three hypothetical scenarios (2 weeks of new-onset exertional chest pain, 2 months of knee pain, and rash for 4 weeks). We examined the relation among patients' preference for initial care by a specialist and their demographic characteristics, global ratings of their primary care physician and health plan, trust in their primary care physician, and other health beliefs and attitudes. Results Averaged for the three scenarios and actual health problem, 13% of patients preferred to see a specialist first. Adjusting for all other covariates, blacks (risk ratio [RR] = 0.55; 95% confidence interval [CI]: 0.20 to 0.92) and Asians (RR = 0.46; 95% CI: 0.19 to 0.75) were much less likely to prefer a specialist than were whites. Patients with less confidence in their primary care physician and greater certainty about needed tests and treatments were more likely to prefer a specialist. These variables, however, did not explain the difference in preference for specialist care among blacks, Asians, and whites. Conclusion Blacks and Asians are less likely than whites to prefer initial care by a specialist. Future studies should examine whether differences in preference for care lead minorities to underutilize appropriate specialty care or lead whites to overuse specialty care.
