Patient-Centered Quality Measures for Dialysis Care: A Report of a Kidney Disease Outcomes Quality Initiative (KDOQI) Scientific Workshop Sponsored by the National Kidney Foundation.

Providing high-quality patient-centered care is the central mission of dialysis facilities. Assessing quality and patient-centeredness of dialysis care is necessary for continuous dialysis facility improvement. Based predominantly on readily measured items, current quality measures in dialysis care emphasize biochemical and utilization outcomes, with very few patient-reported items. Additionally, current metrics often do not account for patient preferences and may compromise patient-centered care by limiting the ability of providers to individualize care targets, such as dialysis adequacy, based on patient priorities rather than a fixed numerical target. Developing, implementing, and maintaining a quality program using readily quantifiable data while also allowing for individualization of care targets that emphasize the goals of patients and their care partners provided the motivation for a September 2022 Kidney Disease Outcomes Quality Initiative (KDOQI) Workshop on Patient-Centered Quality Measures for Dialysis Care. Workshop participants focused on 4 questions: (1) What are the outcomes that are most important to patients and their care partners? (2) How can social determinants of health be accounted for in quality measures? (3) How can individualized care be effectively addressed in population-level quality programs? (4) What are the optimal means for collecting valid and robust patient-reported outcome data? Workshop participants identified numerous gaps within the current quality system and favored a conceptually broader, but not larger, quality system that stresses highly meaningful and adaptive measures that incorporate patient-centered principles, individual life goals, and social risk factors. Workshop participants also identified a need for new, low-burden tools to assess patient goals and priorities.

Association Between Nephrologist Ownership of Dialysis Facilities and Clinical Outcomes.

Importance: Ownership of US dialysis facilities presents a financial conflict of interest for nephrologists, who may change their clinical practice to improve facility profitability. Objective: To investigate the association between nephrologist ownership of freestanding dialysis facilities and clinical outcomes. Design, Setting, and Participants: This cross-sectional study was conducted using US Renal Data System data linked to a data set of freestanding nonpediatric dialysis facility owners. Participants were a sample of all adults with fee-for-service Medicare receiving dialysis for end-stage kidney disease from January 2017 to November 2017 at included facilities. Data were analyzed from April 2020 through August 2022. Exposures: Outcomes associated with nephrologist ownership were assessed using a difference-in-differences analysis comparing the difference in outcomes between patients treated by nephrologist owners and patients treated by nonowners within facilities owned by nephrologists after accounting for differences in patient outcomes between nephrologist owners and nonowners in other facilities. Main Outcomes and Measures: Outcomes plausibly associated with nephrologist ownership were evaluated: (1) treatment volumes (missed treatments and transplant waitlist status); (2) erythropoietin-stimulating agent (ESA) use and related outcomes (anemia, defined as hemoglobin level <10 g/dL, and blood transfusions), (3) quality metrics (mortality, hospitalizations, 30-day readmissions, hemodialysis adequacy, arteriovenous fistula use, and hemodialysis catheter use for ≥3 months), and (4) home dialysis use. Results: A cohort of 251 651 patients (median [IQR] age, 66 [46-85] years; 112 054 [44.5%] women; 9765 Asian [3.9%], 86 837 Black [34.5%], and 148 617 White [59.1%]; 38 938 Hispanic [15.5%]) receiving dialysis for end-stage kidney disease were included. Patient treatment by nephrologist owners at their owned facilities was associated with a 2.4 percentage point (95% CI, 1.1-3.8 percentage points) higher probability of home dialysis, a 2.2 percentage point (95% CI, 3.6-0.7 percentage points) lower probability of receiving an ESA, and no significant difference in anemia or blood transfusions. Patient treatment by nephrologist owners at their owned facilities was not associated with differences in missed treatments, transplant waitlisting, mortality, hospitalizations, 30-day readmissions, hemodialysis adequacy, or fistula or long-term dialysis catheter use. Conclusions and Relevance: This cross-sectional cohort study found that nephrologist ownership was associated with increased home dialysis use, decreased ESA use, and no change in anemia or blood transfusions.

A Blueprint for Increasing Ethnic and Racial Diversity in U.S. Residency Training Programs.

PROBLEM: People who identify as African Americans, Latinos, or from indigenous backgrounds, are dramatically underrepresented in the U.S. physician workforce. It is critical for academic health centers to recognize racial and ethnic diversity at the residency level and implement changes to enhance diversity among trainees. APPROACH: The Office of Graduate Medical Education (GME) at the University of Pennsylvania Health System (UPHS) developed a multipronged approach to enhance diversity and inclusion (D&I) among residency trainees. The approach included the development of an underrepresented in medicine (UIM) professional network; UIM-focused visiting clerkship programs; holistic review implementation by selection committees; and targeted outreach to UIM candidates, overseen by an associate designated institutional official for UIM Affairs. The authors reported demographic data on residency applicants invited for interviews and matching for all programs at UPHS from 2014-2015 (baseline) to 2020-2021. They also reported data on maximum ranking number programs reached to fill their positions and the average United States Medical License Examination (USMLE) Step 1 scores of matched candidates. Finally, they discussed the implications for leaders who wish to enhance D&I at academic health centers. OUTCOMES: During the baseline year (2014-2015), UIMs represented 12.1% of interviewees and 8.7% of all matched candidates into UPHS residency programs. Over the successive 6 years after incremental implementation of the approach, UIM representation steadily increased. In 2020-2021, UIMs represented 23.2% of interviewees and 26.4% of matched candidates. Programs' maximum rank number to fill and USMLE Step 1 scores of matched candidates remained relatively unchanged. NEXT STEPS: The UPHS Office of GME incorporated a purposeful approach to enhance the D&I of its residents. Across 6 years of implementation, UIM representation among resident matches tripled while quantitative program and candidate metrics remained unchanged. Similar efforts should be given further consideration for implementation and evaluation nationwide.

Analysis of Performance Trends from 2010-2019 on the American Board of Internal Medicine Nephrology Certifying Exam.

BACKGROUND: The pass rate on the American Board of Internal Medicine (ABIM) nephrology certifying exam has declined and is among the lowest of all internal medicine (IM) subspecialties. In recent years, there have also been fewer applicants for the nephrology fellowship match. METHODS: This retrospective observational study assessed how changes between 2010 and 2019 in characteristics of 4094 graduates of US ACGME-accredited nephrology fellowship programs taking the ABIM nephrology certifying exam for the first time, and how characteristics of their fellowship programs were associated with exam performance. The primary outcome measure was performance on the nephrology certifying exam. Fellowship program pass rates over the decade were also studied. RESULTS: Lower IM certifying exam score, older age, female sex, international medical graduate (IMG) status, and having trained at a smaller nephrology fellowship program were associated with poorer nephrology certifying exam performance. The mean IM certifying exam percentile score among those who subsequently took the nephrology certifying exam decreased from 56.7 (SD, 27.9) to 46.1 (SD, 28.7) from 2010 to 2019. When examining individuals with comparable IM certifying exam performance, IMGs performed less well than United States medical graduates (USMGs) on the nephrology certifying exam. In 2019, only 57% of nephrology fellowship programs had aggregate 3-year certifying exam pass rates ≥80% among their graduates. CONCLUSIONS: Changes in IM certifying exam performance, certain trainee demographics, and poorer performance among those from smaller fellowship programs explain much of the decline in nephrology certifying exam performance. IM certifying exam performance was the dominant determinant.

Smart-phone Based Geofencing: A Novel Approach to Monitoring Clinical Work Hours in Surgery Residency.

OBJECTIVE: The Accreditation Council for Graduate Medical Education specifies strict requirements for clinical work hours during residency training, with serious consequences for violations. Self-reporting of work hours by trainees can be inaccurate due to recall bias, giving program directors limited data to influence change. We aimed to assess the impact of a smart-phone based geofencing application on submission rates for work hours and reported violations in a general surgery residency program at a university-based medical center. We also examined resident perceptions surrounding implementation and use of the application. METHODS: We compared clinical work hours submitted and violations reported during the pilot period (October-November 2019) with the months prior to the launch of the application (July-August 2019). PGY1 and PGY2 residents were eligible to use the application during and after this pilot period. Semi-structured interviews were used to assess resident perceptions. A retrospective review was conducted to compare reporting during the same time period from the prior academic year (2018-2019) for historical reference. Paired t-tests were used to analyze the data. RESULTS: Twenty-six residents (15 PGY1, 11 PGY2) were eligible for the intervention and 23 residents (88%) used the application. The mean number of violations reported decreased significantly during the pilot period compared with the months prior to the intervention (4.5 vs. 11, p = 0.04). The total rate of submissions was not significantly different after the intervention (85% vs. 82%, p = 0.42). The PGY1 mean submission rate decreased during the pilot period (91%-75%, p = 0.21) while the PGY2 submission rate increased (77%-91%, p = 0.07). Compared with historical data, there was an increase in overall total submission rates between academic years 2018/2019 and 2019/2020 (74% vs. 79%, p = 0.047) and an associated decrease in the mean number of monthly violations (14 vs. 6.25, p = 0.004). Thirteen (50%) residents (8 PGY1, 5 PGY2) volunteered for semi-structured interviews. Most participants found the application useful for recording and reporting clinical work hours. They noted an ease in the administrative burden as well as more accurate reporting associated with automated logging. Use of the application was not perceived to limit engagement with patient care; however, there were privacy concerns and some technical barriers were identified. The messaging regarding the application's use was identified as critical for implementation. CONCLUSIONS: The "real-time" data provided by a geofencing application in our program helped to reduce the number of work-hour violations reported and did not diminish resident engagement with patient care. Decreasing the administrative burden of recording work hours coupled with improving transparency and accuracy of submissions may be important mechanisms.

Hypoxia-Inducible Factor Stabilization as an Emerging Therapy for CKD-Related Anemia: Report From a Scientific Workshop Sponsored by the National Kidney Foundation.

The National Kidney Foundation convened an interdisciplinary international workshop in March 2019 to discuss the potential role of a new class of agents for the treatment of anemia in patients with chronic kidney disease (CKD): the hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs). International experts with expertise in physiology, biochemistry, structural chemistry, translational medicine, and clinical management of anemia participated. Participants reviewed the unmet needs of current anemia treatment, the biology of hypoxia-inducible factor, the pharmacology of prolyl hydroxylase inhibitors, and the results of phase 2 clinical trials of HIF-PHIs among patients with CKD, both those treated by dialysis and those not receiving kidney replacement therapy. The results of key phase 3 clinical trials of HIF-PHIs available as of the time of writing are also included in this report, although they appeared after the workshop was completed. Participants in the workshop developed a number of recommendations for further examination of HIF-PHIs, which are summarized in this report and include long-term safety issues, potential benefits, and practical considerations for implementation including patient and provider education.

The RCA ReCAst: A Root Cause Analysis Simulation for the Interprofessional Clinical Learning Environment.

PROBLEM: The Accreditation Council for Graduate Medical Education calls for resident participation in real or simulated interprofessional analysis of a patient safety event. There are far more residents who must participate in these investigations than available institutional root cause analyses (RCAs) to accommodate them. To correct this imbalance, the authors developed an institutionally sponsored, interprofessional RCA simulation program and implemented it across all graduate medical education (GME) residency programs at the Hospital of the University of Pennsylvania. APPROACH: The authors developed RCA simulations based upon authentic adverse events experienced at their institution. To provide relevance to all GME programs, RCA simulation cases varied widely and included examples of errors involving high-risk medications, communication, invasive procedures, and specimen labeling. Each simulation included residents and other health care professionals such as nurses or pharmacists whose disciplines were involved in the actual event. Participants adopted the role of RCA investigation team, and in small groups systematically progressed through the RCA process. OUTCOMES: A total of 289 individuals from 18 residency programs participated in an RCA simulation in 2019-2020. This included 84 interns (29%), 123 residents (43%), 20 attending physicians (7%), and 62 (21%) other health care professionals. There was an increase in ability of GME trainees to correctly identify factors required for an RCA investigation (62% pre vs 80% post, P = .02) and an increase in intent to "always report" for each adverse event category (3% pre vs 37% post, P < .001) following the simulation. NEXT STEPS: The authors plan to expand the RCA simulation program to other GME clinical sites while striving to involve all GME learners in this educational experience at least once during training. Additionally, by collaborating with health system patient safety leaders, they will annually review all new RCAs to identify cases suitable for simulation adaptation.

A Randomized Trial of Strategies Using Darbepoetin Alfa To Avoid Transfusions in CKD.

BACKGROUND: Exposure to high doses or a high cumulative dose of erythropoiesis-stimulating agents (ESAs) may contribute to cardiovascular events in patients with CKD and anemia. Whether using a low fixed ESA dose versus dosing based on a hemoglobin-based, titration-dose algorithm in such patients might reduce risks associated with high ESA doses and decrease the cumulative exposure-while reducing the need for red blood cell transfusions-is unknown. METHODS: In this phase-3, randomized trial involving 756 adults with stage-3 to -5 CKD and anemia, we evaluated incidence of red blood cell transfusions for participants randomized to receive darbepoetin given as a fixed dose (0.45 µg/kg every 4 weeks) versus administered according to a hemoglobin-based, titration-dose algorithm, for up to 2 years. Participants received transfusions as deemed necessary by the treating physician. RESULTS: There were 379 patients randomized to the fixed-dose group, and 377 to the titration-dose group. The percentage of participants transfused did not differ (24.1% and 24.4% for the fixed-dose and titration-dose group, respectively), with similar time to first transfusion. The titration-dose group achieved significantly higher median hemoglobin (9.9 g/dl) compared with the fixed-dose group (9.4 g/dl). The fixed-dose group had a significantly lower median cumulative dose of darbepoetin (median monthly dose of 30.9 µg) compared with the titration-dose group (53.6 µg median monthly dose). The FD and TD group received a median (Q1, Q3) cumulative dose per 4 weeks of darbepoetin of 30.9 (21.8, 40.0) µg and 53.6 (31.1, 89.9) µg, respectively; the median of the difference between treatment groups was -22.1 (95% CI, -26.1 to -18.1) µg. CONCLUSIONS: These findings indicate no evidence of difference in incidence of red blood cell transfusion for a titration-dose strategy versus a fixed-dose strategy for darbepoetin. This suggests that a low fixed dose of darbepoetin may be used as an alternative to a dose-titration approach to minimize transfusions, with less cumulative dosing.

Effect of Neighborhood Food Environment and Socioeconomic Status on Serum Phosphorus Level for Patients on Chronic Dialysis.

BACKGROUND: Elevated blood phosphorus levels are common and associated with a greater risk of death for patients receiving chronic dialysis. Phosphorus-rich foods are prevalent in the American diet, and low-phosphorus foods, including fruits and vegetables, are often less available in areas with more poverty. The relative contributions of neighborhood food availability and socioeconomic status to phosphorus control in patients receiving dialysis are unknown. METHODS: Using longitudinal data from a national dialysis provider, we constructed hierarchical, linear mixed-effects models to evaluate the relationships between neighborhood food environment or socioeconomic status and serum phosphorus level among patients receiving incident dialysis. RESULTS: Our cohort included 258,510 patients receiving chronic hemodialysis in 2005-2013. Median age at dialysis initiation was 64 years, 45% were female, 32% were Black, and 15% were Hispanic. Within their residential zip code, patients had a median of 25 "less-healthy" food outlets (interquartile range, 11-40) available to them compared with a median of four "healthy" food outlets (interquartile range, 2-6). Living in a neighborhood with better availability of healthy food was not associated with a lower phosphorus level. Neighborhood income also was not associated with differences in phosphorus. Patient age, race, cause of ESKD, and mean monthly dialysis duration were most closely associated with phosphorus level. CONCLUSIONS: Neither neighborhood availability of healthy food options nor neighborhood income was associated with phosphorus levels in patients receiving chronic dialysis. Modifying factors, such as nutrition literacy, individual-level financial resources, and adherence to diet restrictions and medications, may be more powerful contributors than food environment to elevated phosphorus.

Reflections on a Crisis in Graduate Medical Education: The Closure of Hahnemann University Hospital.

In June 2019, Hahnemann University Hospital (HUH) in Philadelphia became the largest U.S. teaching hospital to announce its closure and the closure of all of its graduate medical education (GME) programs, which displaced more than 550 residents, fellows, and other trainees. In addition to the displaced trainees, the HUH closure involved many stakeholders at both the closing hospital and hospitals willing to accept transferred residents and fellows-program directors and coordinators, designated institutional officials (DIOs), and hospital executives-as well as the Accreditation Council for Graduate Medical Education, the Centers for Medicare and Medicaid Services, the National Resident Matching Program, and other organizations. Given the rarity of such events, those involved had little experience or expertise in dealing with the closure of so many GME programs at one time. In this Invited Commentary, the DIOs of HUH and 4 other area teaching hospitals detail their experiences working to find new training opportunities for the displaced residents and fellows, discussing lessons learned and providing recommendations to prepare for any future teaching hospital closures. Stakeholder organizations should work together to develop a "playbook" for use during future closures so that the chaos that occurred this time can be avoided.
