Kidney transplant (KT) recipients face post-transplant health issues. Immunosuppressive agents can cause hyperlipidemia, hypertension, post-transplant diabetes, and glomerulopathy. Post-transplant weight gain and decreased activity are associated with poor quality of life, sleep, and cardiometabolic outcomes. This study will test the feasibility and acceptability of a culturally-tailored, diet and exercise intervention for KT patients delivered immediately post-transplant using novel technology. A registered dietitian nutritionist (RDN) and physical rehabilitation therapist will examine participants’ cultural background, preferences, and health-related obstacles (with consultation from the transplant team) to create an individualized exercise and meal plan. The RDN will provide medical nutrition therapy via the nutrition care process throughout the course of the intervention. The Twistle® Patient Engagement Platform will be used to deliver and collect survey data, communicate with participants, and promote retention. Outcomes to be assessed include: intervention feasibility and acceptability, and intervention efficacy on patients’ adherence, medical, quality of life, and occupational outcomes.

Disordered iron and mineral homeostasis are interrelated complications of chronic kidney disease that may influence cardiovascular and kidney outcomes. In a prospective analysis of 3747 participants in the Chronic Renal Insufficiency Cohort Study, we investigated risks of mortality, heart failure, end-stage kidney disease (ESKD), and atherosclerotic cardiovascular disease according to iron status, and tested for mediation by C-terminal fibroblast growth factor 23 (FGF23), hemoglobin and parathyroid hormone. Study participants were agnostically categorized based on quartiles of transferrin saturation and ferritin as: “Iron Replete” (27.1% of participants; referent group for all outcomes analyses), “Iron Deficiency” (11.1%), “Functional Iron Deficiency” (7.6%), “Mixed Iron Deficiency” (iron indices between the Iron Deficiency and Functional Iron Deficiency groups; 6.3%), “High Iron” (9.2%), or “Non-Classified” (the remaining 38.8% of participants). In multivariable-adjusted Cox models, Iron Deficiency independently associated with mortality (hazard ratio 1.28, 95% confidence interval 1.04–1.58) and heart failure (1.34, 1.05–1.72). Mixed Iron Deficiency associated with mortality (1.61, 1.27–2.04) and ESKD (1.33, 1.02–1.73). High Iron associated with mortality (1.54, 1.24–1.91), heart failure (1.58, 1.21–2.05), and ESKD (1.41, 1.13–1.77). Functional Iron Deficiency did not significantly associate with any outcome, and no iron group significantly associated with atherosclerotic cardiovascular disease. Among the candidate facilitators, FGF23 most significantly mediated the risks of mortality and heart failure conferred by Iron Deficiency. Thus, alterations in iron homeostasis associated with adverse cardiovascular and kidney outcomes in patients with chronic kidney disease.

Rationale and objective Sleep problems affect more than half of patients receiving dialysis and are associated with increased risk of mortality, cardiovascular events, depression and impaired functioning and quality of life. Symptoms such as fatigue and exhaustion may be attributed to sleep problems or sleep disorders, as well as the burden of kidney disease and treatment. This study aims to describe the patient perspectives on the reasons, impact and management of sleep problems in dialysis. Study design Systematic review and thematic synthesis of qualitative studies that report patient experience and perspectives on sleep in dialysis. Setting and population Patients receiving dialysis. Search strategy and sources MEDLINE, Embase, PsycINFO, CINAHL, reference lists and PhD dissertations were searched from inception to August 2019. Data extraction All text from the results/conclusion of the primary studies. Analytical approach Thematic synthesis. Results We included 48 studies involving 1156 participants from 16 countries. We identified six themes: dominating demands of treatment (with subthemes of: demanding and relentless schedule, regret for wasted time); scheduling and control (managing sleep routines, napping and nocturnal sleep disruption, meditative aids); disruptions due to dialysis (unsettled sleep, hypervigilance and worry); symptoms depriving sleep (difficulty falling asleep, constant waking); overwhelmed and without choice (futility of sleep, uncontrollable exhaustion, restlessness is irrepressible); and as a coping mechanism (avoiding anxiety, alleviating symptoms, combating boredom). Limitations Most studies were conducted in high-income, English-speaking countries. Conclusion The treatment and symptom burden of dialysis disrupts and deprives patients of sleep, which leads to overwhelming and uncontrollable exhaustion. Better management of symptoms and effective strategies to manage sleep routines may improve sleep quality for better overall health in patients receiving dialysis.

Patients with CKD and ESRD are vulnerable to increased mortality rates and other poor outcomes. Among those with ESRD, their health-related quality of life (HRQOL) is shown little to no improvement as they undergo treatments such as dialysis and providers concurrently manage other health issues that complicate their already vulnerable state. This review synthesizes evidence demonstrating that a focus on measuring and monitoring patient-reported outcomes (PRO) such as pain and depression can improve HRQOL. Patient-centered care has the potential to create an efficient way for clinicians to address specific challenges facing patients. While there is an emerging literature assessing the use of PROs in kidney research, by examining relevant research in other disciplines it is possible to generate better ways to use PROs in this high-risk population. Electronic health records as well as various other electronic methods of communication between the clinician and patient may serve to accelerate the trajectory toward patient-centered care using PROs.

Kidney transplant evaluation (KTE) is a period marked by many stressors for patients, which may lead to poorer patient-reported outcomes (PROs). Research on the association of cultural and psychosocial factors with PROs during KTE is lacking, even though cultural and psychosocial variables may mitigate the relationship between acceptance status and PROs.Using a prospective cohort study of 955 adults referred for KTE, we examined whether cultural factors and psychosocial characteristics, assessed at the initiation of KTE, are associated with PROs at KTE completion, controlling for demographics and medical factors. Also, we analyzed whether these factors moderate the relationship between transplant acceptance status and PROs.In multivariable regression models, a stronger sense of mastery was associated with higher physical and mental QOL. A stronger sense of self-esteem was associated with higher kidney-specific QOL. Depression was associated with a lower mental QOL, but only in those who were accepted for transplant. Having low levels of external locus of control was associated with better mental QOL in those who were not accepted for transplant. Higher anxiety was associated with poorer kidney-specific QOL among those who were not accepted for KT, but trust in physician was only associated with greater satisfaction in transplant clinic service for those who were accepted for KT.Targeting interventions to increase patient mastery and external locus of control, and reduce depression and anxiety in patients undergoing kidney transplant evaluation may be useful approaches to improve their experience during this stressful period.

Background Health information exchange (HIE) capabilities are tied to health care organizations' strategic and business goals. As a technology that connects information from different organizations, HIE may be a source of competitive advantage and a path to improvements in performance. Purpose The aim of the study was to identify the impact of hospitals' use of HIE capabilities on outcomes that may be sensitive to changes in various contracting arrangements and referral patterns arising from improved connectivity. Methodology Using a panel of community hospitals in nine states, we examined the association between the number of different data types the hospital could exchange via HIE and changes in market share, payer mix, and operating margin (2010-2014). Regression models that controlled for the number of different data types shared intraorganizationally and other time-varying factors and included both hospital and time fixed effects were used for adjusted estimates of the relationships between changes in HIE capabilities and outcomes. Results Increasing HIE capability was associated with a 13 percentage point increase in a hospital's discharges that were covered by commercial insurers or Medicare (i.e., payer mix). Conversely, increasing intraorganizational information sharing was associated with a 9.6 percentage point decrease in the percentage of discharges covered by commercial insurers or Medicare. Increasing HIE capability or intraorganizational information sharing was not associated with increased market share nor with operating margin. Conclusions Improving information sharing with external organizations may be an approach to support strategic business goals. Practice implications Organizations may be served by identifying ways to leverage HIE instead of focusing on intraorganizational exchange capabilities.

Objective Event notification systems are an approach to health information exchange (HIE) that notifies end-users of patient interactions with the healthcare system through real-time automated alerts. We examined associations between organizational capabilities and perceptions of event notification system use. Materials and Methods We surveyed representatives (n = 196) from healthcare organizations (n = 96) that subscribed to 1 of 3 Health Information Organizations’ event notification services in New York City (response rate = 27%). The survey was conducted in Fall 2017 and Winter 2018. Surveys measured respondent characteristics, perceived organizational capabilities, event notification use, care coordination, and care quality. Exploratory factor analysis was used to identify relevant independent and dependent variables. We examined the relationship between organizational capabilities, care coordination, and care quality using multilevel linear regression models with random effects. Results Respondents indicated that the majority of their organizations provided follow-up care for emergency department visits (66%) and hospital admissions (73%). Perceptions of care coordination were an estimated 57.5% (β = 0.575; P Discussion and Conclusion Healthcare organizations with specific workflow processes and positive perceptions of fit are more likely to use event notification services to improve care coordination and care quality. In addition, event notification capacity and patient consent procedures influence how end-users perceive event notification services.

BACKGROUND: Recent innovations have the potential to disrupt the current paradigm for kidney failure treatment. The US Food and Drug Administration is committed to incorporating valid scientific evidence about how patients weigh the benefits and risks of new devices into their decision making, but to date, premarket submission of patient preference information (PPI) has been limited for kidney devices. With input from stakeholders, we developed a survey intended to yield valid PPI, capturing how patients trade off the potential benefits and risks of wearable dialysis devices and in-center hemodialysis. METHODS: We conducted concept elicitation interviews with individuals receiving dialysis to inform instrument content. After instrument drafting, we conducted two rounds of pretest interviews to evaluate survey face validity, comprehensibility, and perceived relevance. We pilot tested the survey with in-center hemodialysis patients to assess comprehensibility and usability further. Throughout, we used participant input to guide survey refinements. RESULTS: Thirty-six individuals receiving in-center or home dialysis participated in concept elicitation (N=20) and pretest (N=16) interviews. Participants identified reduced fatigue, lower treatment burden, and enhanced freedom as important benefits of a wearable device, and many expressed concerns about risks related to device disconnection—specifically bleeding and infection. We drafted a survey that included descriptions of the risks of serious bleeding and serious infection and an assessment of respondent willingness to wait for a safer device. Input from pretest interviewees led to various instrument modifications, including treatment descriptions, item wording, and risk-level explanations. Pilot testing of the updated survey among 24 in-center hemodialysis patients demonstrated acceptable survey comprehensibility and usability, although 50% of patients required some assistance. CONCLUSIONS: The final survey is a 54-item web-based instrument that will yield estimates of the maximal acceptable risk for the described wearable device and willingness to wait for wearable devices with lower risk.

Key Points Question Is private equity acquisition of nursing homes associated with the quality or cost of care for long-stay nursing home residents? Findings In this cohort study with difference-in-differences analysis of 9864 US nursing homes, including 9632 residents in 302 nursing homes acquired by private equity firms and 249 771 residents in 9562 other for-profit nursing homes without private equity ownership, private equity acquisition of nursing homes was associated with higher costs and increases in emergency department visits and hospitalizations for ambulatory sensitive conditions. Meaning This study suggests that more stringent oversight and reporting on private equity ownership of nursing homes may be warranted., Importance Private equity firms have been acquiring US nursing homes; an estimated 5% of US nursing homes are owned by private equity firms. Objective To examine the association of private equity acquisition of nursing homes with the quality and cost of care for long-stay residents. Design, Setting, and Participants In this cohort study of 302 private equity nursing homes with 9632 residents and 9562 other for-profit homes with 249 771 residents, a novel national database of private equity nursing home acquisitions was merged with Medicare claims and Minimum Data Set assessments for the period from 2012 to 2018. Changes in outcomes for residents in private equity–acquired nursing homes were compared with changes for residents in other for-profit nursing homes. Analyses were performed from March 25 to June 23, 2021. Exposure Private equity acquisitions of 302 nursing homes between 2013 and 2017. Main Outcomes and Measures This study used difference-in-differences analysis to examine the association of private equity acquisition of nursing homes with outcomes. Primary outcomes were quarterly measures of emergency department visits and hospitalizations for ambulatory care–sensitive (ACS) conditions and total quarterly Medicare costs. Antipsychotic use, pressure ulcers, and severe pain were examined in secondary analyses. Results Of the 259 403 residents in the study (170 687 women [65.8%]; 211 154 White residents [81.4%]; 204 928 residents [79.0%] dually eligible for Medicare and Medicaid; mean [SD] age, 79.3 [5.6] years), 9632 residents were in 302 private equity–acquired nursing homes and 249 771 residents were in 9562 other for-profit homes. The mean quarterly rate of ACS emergency department visits was 14.1% (336 072 of 2 383 491), and the mean quarterly rate of ACS hospitalizations was 17.3% (412 344 of 2 383 491); mean (SD) total quarterly costs were $8050.00 ($9.90). Residents of private equity nursing homes experienced relative increases in ACS emergency department visits of 11.1% (1.7 of 15.3; 1.7 percentage points; 95% CI, 0.3-3.0 percentage points; P = .02) and in ACS hospitalizations of 8.7% (1.0 of 11.5; 1.0 percentage point; 95% CI, 0.2-1.1 percentage points; P = .003) compared with residents in other for-profit homes; quarterly costs increased 3.9% (270.37 of 6972.04; $270.37; 95% CI, $41.53-$499.20; P = .02) or $1081 annually per resident. Private equity acquisition was not significantly associated with antipsychotic use (−0.2 percentage points; 95% CI, −1.7 to 1.4 percentage points; P = .83), severe pain (0.2 percentage points; 95% CI, −1.1 to 1.4 percentage points; P = .79), or pressure ulcers (0.5 percentage points; 95% CI, −0.4 to 1.3 percentage points; P = .30). Conclusions and Relevance This cohort study with difference-in-differences analysis found that private equity acquisition of nursing homes was associated with increases in ACS emergency department visits and hospitalizations and higher Medicare costs., This cohort study uses a national database of private equity nursing home acquisitions as well as Medicare data to examine the association of private equity acquisition of nursing homes with the quality and cost of care for long-stay residents.

RATIONALE AND OBJECTIVE: The safety of intensive blood pressure (BP) targets is controversial for persons with chronic kidney disease (CKD). We studied the effects of hypertension treatment on cerebral perfusion and structure in those with and without CKD. STUDY DESIGN: Neuroimaging substudy of a randomized trial. SETTING & PARTICIPANTS: A subset of participants in the Systolic Blood Pressure Intervention Trial who underwent brain MRI studies. Presence of baseline CKD was assessed by estimated glomerular filtration rate (eGFR) and urine albumin to creatinine ratio (UACR). INTERVENTION: Participants were randomly assigned to intensive (systolic BP 30 mg/g (N=151), the effects of intensive versus standard BP treatment on change in global cerebral blood flow, WMLs and total brain volume were 1.91 ml/100g/min (95% CI −3.01, 6.82), 0.003 cm(3) (asinh transformed, 95% CI −0.13, 0.13), and −7.0 cm(3) (95% CI −13.3, −0.3), respectively. The overall treatment effects on cerebral blood flow and total brain volume were not modified by baseline eGFR or UACR; however the effect on WMLs was attenuated in participants with albuminuria (interaction p-value 0.04). LIMITATIONS: Measurement variability due to multi-site design. CONCLUSIONS: Among hypertensive adults with primarily early kidney disease, intensive versus standard blood pressure treatment did not appear to have a detrimental effect on brain perfusion or structure. The findings support the safety of intensive blood pressure treatment targets on brain health in persons with early kidney disease. FUNDING: The Systolic Blood Pressure Intervention Trial was funded by the National Institutes of Health (including the National Heart, Lung, and Blood Institute, the National Institute of Diabetes and Digestive and Kidney Diseases, the National Institute on Aging, and the National Institute of Neurological Disorders and Stroke), and this substudy was funded by the National Institutes of Diabetes and Digestive and Kidney Diseases. TRIAL REGISTRATION: SPRINT was registered at ClinicalTrials.gov with the study number NCT01206062.

Background: On average Black patients have longer LOS than comparable White patients. Longer hospital length of stay (LOS) may be associated with higher readmission risk. However, evidence suggests that the Hospital Readmission Reduction Program (HRRP) reduced overall racial differences in 30-day adjusted readmission risk. Yet, it is unclear whether the HRRP narrowed these LOS racial differences. Objective: We examined the relationship between Medicare-insured Black-White differences in average, adjusted LOS (ALOS) and the HRRP’s implementation and evaluation periods. Methods: Using 2009-2017 data from State Inpatient Dataset from New York, New Jersey, and Florida, we employed an interrupted time series analysis with multivariate generalized regression models controlling for patient, disease, and hospital characteristics. Results are reported per 100 admissions. Results: We found that for those discharged home, Black-White ALOS differences significantly widened by 4.15 days per 100 admissions (95% CI: 1.19 to 7.11, P < 0.001) for targeted conditions from before to after the HRRP implementation period, but narrowed in the HRRP evaluation period by 1.84 days per 100 admissions for every year-quarter (95% CI: −2.86 to −0.82, P < 0.001); for those discharged to non-home destinations, there was no significant change between HRRP periods, but ALOS differences widened over the study period. Black-White ALOS differences for non-targeted conditions remained unchanged regardless of HRRP phase and discharge destination. Conclusion: Increased LOS for Black patients may have played a role in reducing Black-White disparities in 30-day readmission risks for targeted conditions among patients discharged to home.

This cohort study uses Medicare data to assess trends and characteristics among hospitalists who shift practice to settings outside of the hospital.

Background: Presence of chronic kidney disease (CKD Stages 3-5) prior to breast cancer diagnosis may increase the risk of mortality among women with invasive breast cancer. However, the evidence base is limited, and the magnitude of this mortality risk is unknown. Breast cancer therapy may also be altered by presence of CKD. We sought to understand the role of CKD in breast cancer survival, with particular attention to receipt of recommended treatment. Methods: All women diagnosed with invasive breast cancer from 1992-2016 in 18 SEER-Medicare sites (age 66 or older; n= 168701) were evaluated for breast cancer-specific mortality (BCSM) using multivariate Cox models, with estimation of hazard ratios (HR) and 95% confidence intervals (CI). All analyses were adjusted for age, race/ethnicity, diagnosis year, tumor characteristics, and socioeconomic factors, and also for diabetes, myocardial infarction, and congestive heart failure prior to diagnosis. Separate analyses were run according to receipt vs non-receipt of standard of care for breast cancer treatment (defined according to National Comprehensive Cancer Network (NCCN) guidelines. Results: Median follow-up was 63 months (26 months with CKD). Women with CKD were at increased risk of BCSM (CKD Stage 3: HR 1.2; 95% CI 1.0-1.5; CKD Stage 4 HR 1.7; 95% CI 1.3-2.2; CKD Stage 5/End Stage Renal Disease HR 1.5; 95% CI 1.1-2.1), compared to women without CKD. In analyses of any CKD, restricted to women who met NCCN guideline therapy recommendations, women had an elevated risk of BCSM regardless of whether they did (HR 1.6; 95% CI 1.1-2.1) or did not (HR 1.4; 95% CI 1.0-1.8) receive recommended chemotherapy, and whether they did (HR 1.6; 95% CI 1.1-2.3) or did not (HR 1.3; 95% CI 0.9-2.0) receive recommended radiotherapy. Discussion: Women with CKD have an increased risk of breast cancer mortality regardless of receipt of guideline-based treatment. CKD is underascertained in Medicare claims data, thus the reported results (likely underestimates) will be presented with sensitivity analyses. CKD may influence breast cancer outcomes due to associated systemic inflammation and comorbid conditions, as well as release of soluble mediators such as cytokines, chemokines, growth factors, and factors involved in remodeling of the extracellular matrix and epithelial-mesenchymal transition. As such factors involved in CKD progression also influence cancer, increased understanding may provide clues to ameliorate adverse outcomes in both disease entities.

Background: Uremic pruritus (UP) and restless legs syndrome (RLS) are highly prevalent complaints among patients with end-stage renal disease (ESRD) undergoing chronic dialysis. These chronic troublesome symptoms lead to a significant decrease in quality of life (QOL) and increase in mortality rate. Despite their distressing characteristics, these symptoms usually remain under-recognized by healthcare providers. Therefore, careful history intake, and stepwise treatment are essential. Numerous pharmacological and non-pharmacological treatments have been demonstrated to help in controlling these 2 conditions. Summary: In this review, we discuss the latest findings regarding UP and RLS among ESRD patients on maintenance dialysis. We also examine different treatment options in this group of patients. The majority of these patients do not have the opportunity to receive a kidney transplant and need other treatments for these burdensome symptoms in order to improve their QOL and prognosis. Key Messages: UP and RLS are common but underdiagnosed conditions in ESRD patients on maintenance dialysis that are related to a decline in patients’ QOL and poor prognosis. The pathophysiology of these conditions remains not well understood. Therefore, controversies still exist on treatment options. Treating these conditions provides an opportunity to improve the health-related QOL and outcomes of dialysis patients.

Rationale & Objective Fatigue is a highly prevalent and debilitating symptom in patients on hemodialysis therapy due to the uremic milieu, the hemodialysis treatment itself, and other comorbid conditions. However, fatigue remains underrecognized and the consequences are underappreciated because it may not be visible in clinical settings. This study aims to describe the experience that patients undergoing maintenance hemodialysis have with fatigue. Study Design Systematic review and thematic synthesis of qualitative studies. Setting & Study Populations Patients undergoing hemodialysis. Search Strategy & Sources MEDLINE, Embase, PsycINFO, CINAHL, reference lists, and PhD dissertations were searched from inception to October 2018. Data Extraction All text from the results/conclusion of the primary studies. Analytical Approach Thematic synthesis. Results 65 studies involving 1,713 participants undergoing hemodialysis were included. We identified 4 themes related to fatigue: debilitating and exhausting burden of dialysis (bodily depletion, trapped in a vicious cycle of postdialysis exhaustion, vigilance and worry inhibiting rest, tiresome and agonizing regimen, and without remedy and relief), restricted life participation (deprived of time, managing energy reserves, frustrating need to rest, and joys foregone), diminishing capacities to fulfil relationship roles (losing ability to work and provide for family, failing as a parent, lacking stamina for sexual intimacy, and relying on others), and vulnerable to misunderstanding (being criticized for the need to rest and failing to meet expectations). Limitations Non-English articles were excluded and most studies were conducted in high-income countries. Conclusions For patients undergoing hemodialysis who experience fatigue, fatigue is a profound and relentless exhaustion that pervades the entire body and encompasses weakness. The fatigue drains vitality in patients and constrains their ability to do usual activities and fulfill their roles and meet personal aspirations. Explicit recognition of the impact of fatigue and establishing additional effective interventions to improve fatigue are needed.

Objective Enterprise health information exchange (HIE) and a single electronic health record (EHR) vendor solution are 2 information exchange approaches to improve performance and increase the quality of care. This study sought to determine the association between adoption of enterprise HIE vs a single vendor environment and changes in unplanned readmissions. Materials and Methods The association between unplanned 30-day readmissions among adult patients and adoption of enterprise HIE or a single vendor environment was measured in a panel of 211 system-member hospitals from 2010 through 2014 using fixed-effects regression models. Sample hospitals were members of health systems in 7 states. Enterprise HIE was defined as self-reported ability to exchange information with other members of the same health system who used different EHR vendors. A single EHR vendor environment reported exchanging information with other health system members, but all using the same EHR vendor. Results Enterprise HIE adoption was more common among the study sample than EHR (75% vs 24%). However, adoption of a single EHR vendor environment was associated with a 0.8% reduction in the probability of a readmission within 30 days of discharge. The estimated impact of adopting an enterprise HIE strategy on readmissions was smaller and not statically significant. Conclusion Reductions in the probability of an unplanned readmission after a hospital adopts a single vendor environment suggests that HIE technologies can better support the aim of higher quality care. Additionally, health systems may benefit more from a single vendor environment approach than attempting to foster exchange across multiple EHR vendors.

OBJECTIVE: To evaluate the effect of the 2013–2014 Affordable Care Act (ACA) Medicaid Primary Care Rate Increase on Medicaid-insured women’s prenatal care utilization, overall and by race and ethnicity. METHODS: We employed a difference-in-differences design, using births data from the 2010–2014 National Vital Statistics System. Our study population included approximately 6.2 million births to Medicaid insured mothers conceived between April 2009 and March 2014. Our treatment group was births in states with a large (relative to small) fee bump, defined as having a Medicaid-to-Medicare fee ratio below the median of all states (0.7) in 2012. Our control group was births in states with a small fee bump. Prenatal care utilization measures included initiation of prenatal care in the first trimester and number of prenatal care visits. RESULTS: Non-Hispanic Black women giving births in large fee bump states had 9% higher odds (95% CI 1.02, 1.17) of initiating prenatal care in the first trimester during the fee bump period, compared to small fee bump states. Prenatal care visits in this group also increased by 0.24 (95% CI 0.10, 0.39), 2.4% of the mean. A smaller increase in prenatal care visits of 0.17 (95% CI 0.00, 0.33) was found among non-Hispanic Whites. The fee bump had no impact among Hispanics or non-Hispanic women of other races. CONCLUSIONS FOR PRACTICE: The Medicaid “fee bump” improved prenatal care utilization for non-Hispanic Black and White women. Policymakers may consider reinstating higher Medicaid reimbursements to improve access to care for disadvantaged populations.

Objective To quantify the impact of two approaches (directed and query-based) to health information exchange (HIE) on potentially avoidable use of health care services. Data sources/study setting Data on ambulatory care providers' adoption of HIE were merged with Medicare fee-for-service claims from 2008 to 2014. Providers were from 13 counties in New York served by the Rochester Regional Health Information Organization (RHIO). Study design Linear regression models with provider and year fixed effects were used to estimate changes in the probability of utilization outcomes for Medicare beneficiaries attributed to providers adopting directed and/or query-based HIE compared with beneficiaries attributed to providers who had not adopted HIE. Data collection Providers' HIE adoption status was determined through Rochester RHIO registration records. RHIO and claims data were linked via National Provider Identifiers. Principal findings Query-based HIE adoption was associated with a 0.2 percentage point reduction in the probability of an ambulatory care sensitive hospitalization and a 1.1 percentage point decrease in the likelihood of an unplanned readmission. Directed HIE adoption was not associated with any outcome. Conclusions The Centers for Medicare & Medicaid Services' (CMS) EHR certification criteria includes requirements for directed HIE, but not query-based HIE. Pending further research, certification criteria should place equal weight on facilitating query-based and directed exchange.

The delivery of medical care services in U.S. nursing homes (NHs) is dependent on a workforce that comprises physicians, nurse practitioners, and physician assistants. Each of these disciplines operates under a unique regulatory framework while adhering to common standards of care. NH provider characteristics and their roles in NH care can illuminate potential links to clinical outcomes and overall quality of care with important policy and cost implications. This perspective provides an overview of what is currently known about medical provider practice in NH and organizational models of practice. Links to quality, both conceptual and established, are presented as is a research and policy agenda that addresses the gaps in the evidence base within the context of our ever-changing health care landscape.

This study examines whether skilled nursing facilities (SNFs) that consistently provided more rehabilitation therapy than other SNFs had lower 30-day rehospitalization rates. A cross-sectional analysis of 11 866 SNFs in the United States compared 30-day rehospitalization rates of SNFs that consistently provided more rehabilitation therapy to other SNFs using linear regression models. High-billing SNFs were defined as the 10% of SNFs with the highest proportions of Medicare fee-for-service claims that just surpassed the therapy minute threshold for the highest payment category. After controlling for patient and facility characteristics, high-billing SNFs had higher 30-day rehospitalization rates as well as longer median length of stay and greater mean cost per stay. Small reductions in the amount of therapy provided are unlikely to increase 30-day rehospitalization rates in SNFs. This has important consequences for the recently implemented patient-driven payment model, which incentivizes SNFs to provide less rehabilitation therapy.

Background:Length of stay (LOS), a metric of hospital efficiency, differs by race/ethnicity and socioeconomic status (SES) and longer LOS is associated with adverse health outcomes. Historically, projects to improve LOS efficiency have yielded LOS reductions by 0.3 to 0.7 days per admission.Objective:To assess differences in average adjusted length of stay (aALOS) over time by race/ethnicity, and SES stratified by discharge destination (home or non-home).Method:Data were obtained from 2009-2014 Healthcare Cost and Utilization Project State Inpatient Datasets for New York, New Jersey, and Florida. Multivariate generalized linear models were used to examine trends in aALOS differences by race/ethnicity, and by high vs low SES patients (defined first vs fourth quartile of median income by zip code) controlling for patient, disease and hospital characteristics.Results:For those discharged home, racial/ethnic and SES aALOS differences remained stable from 2009 to 2014. However, among those discharged to non-home destinations, Black vs White aALOS differences increased from 0.21 days in Q1 2009, (95% confidence interval (CI): 0.13 to 0.30) to 0.32 days in Q3 2013, (95% CI: 0.23 to 0.40), and for low vs high SES patients from 0.03 days in Q1 2009 (95% CI: -0.04 to 0.1) to 0.26 days, (95% CI: 0.19 to 0.34). Notably, for patients not discharged home, racial/ethnic and SES aALOS differences increased and persisted after Q3 2011, coinciding with the introduction of the Affordable Care Act (ACA).Conclusion:Further research to understand the ACA’s policy impact on hospital efficiencies, and relationship to racial/ethnic and SES differences in LOS is warranted.

This case series examines the increase in acquisitions of hospice agencies by private equity firms and publicly traded corporations from 2011 to 2019.

Background: Converting electronic health record (EHR) entries to useful clinical inferences requires one to address the poor scalability of existing implementations of Generalized Linear Mixed Models (GLMM) for repeated measures. The major computational bottleneck concerns the numerical evaluation of multivariable integrals, which even for the simplest EHR analyses may involve millions of dimensions (one for each patient). The hierarchical likelihood (h-lik) approach to GLMMs is a methodologically rigorous framework for the estimation of GLMMs that is based on the Laplace Approximation (LA), which replaces integration with numerical optimization, and thus scales very well with dimensionality. Methods: We present a high-performance implementation of the h-lik for GLMMs in the R package TMB. Using this approach, we examined the relation of repeated serum potassium measurements and survival in the Cerner Real World Data (CRWD) EHR database. Analyzing this data requires the evaluation of an integral in over 3 million dimensions, putting this problem beyond the reach of conventional approaches. We also assessed the scalability and accuracy of LA in smaller samples of 1 and 10% size of the full dataset that were analyzed via the a) original, interconnected Generalized Linear Models (iGLM), approach to h-lik, b) Adaptive Gaussian Hermite (AGH) and c) the gold standard of Markov Chain Monte Carlo (MCMC) for multivariate integration. Results: Random effects estimates generated by the LA were within 10% of the values obtained by the iGLMs, AGH and MCMC techniques. The H-lik approach was 4-30 times faster than AGH and nearly 800 times faster than MCMC. The major clinical inferences in this problem are the establishment of the non-linear relationship between the potassium level and the risk of mortality, as well as estimates of the individual and health care facility sources of variations for mortality risk in CRWD. Conclusions: We found that the combination of the LA and AD offers a computationally efficient, numerically accurate approach for the analysis of extremely large, real world repeated measures data via the h-lik approach to GLMMs. The clinical inference from our analysis may guide choices of threatment thresholds for treating potassium disorders in the clinic.

Measuring and monitoring quality of life (QOL) in ESRD may contribute to more patient-centered care and higher-quality care. This chapter reviews unique issues impacting the QOL of patients with ESRD. It reviews the literature comparing QOL of patients receiving renal replacement therapies through different dialysis modalities. There is a detailed discussion of strategies to assess QOL and issues related to its measurement. The chapter also reviews the literature on interventions designed to improve QOL and concludes with recommendations and future directions of the field.

Rationale & Objectives Adiposity and physical fitness levels are major drivers of cardiometabolic risk, but these relationships have not been well-characterized in chronic kidney disease (CKD). We examined the associations of visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), intrahepatic fat, and physical function with inflammation, insulin resistance, and adipokine levels in patients with CKD. Study Design Prospective cohort study. Setting & Participants Participants with stages 3-5 CKD not receiving maintenance dialysis, followed up at one of 8 clinical sites in the Chronic Renal Insufficiency Cohort (CRIC) Study, and who underwent magnetic resonance imaging of the abdomen at an annual CRIC Study visit (n = 419). Predictors VAT volume, SAT volume, intrahepatic fat, body mass index, waist circumference, and time taken to complete the 400-m walk test (physical function). Outcomes Markers of inflammation (interleukin 1β [IL-1β], IL-6, tumor necrosis factor receptor 1 [TNFR1], and TNFR2), insulin resistance (homeostasis model assessment of insulin resistance), and adipokine levels (adiponectin, total and high molecular weight, resistin, and leptin). Analytical Approach Multivariable linear regression of VAT and SAT volume, intrahepatic fat, and physical function with individual markers (log-transformed values), adjusting for relevant covariates. Results Mean age of the study population was 64.3 years; 41% were women, and mean estimated glomerular filtration rate was 53.2 ± 14.6 (SD) mL/min/1.73 m2. More than 85% were overweight or obese, and 40% had diabetes. Higher VAT volume, SAT volume, and liver proton density fat fraction were associated with lower levels of total and high-molecular-weight adiponectin, higher levels of leptin and insulin resistance, and lower high-density lipoprotein cholesterol and higher serum triglyceride levels. A slower 400-m walk time was associated only with higher levels of leptin, total adiponectin, plasma IL-6, and TNFR1 and did not modify the associations between fat measures and cardiometabolic risk factors. Limitations Lack of longitudinal data and dietary details. Conclusions Various measures of adiposity are associated with cardiometabolic risk factors. Physical function was also associated with the cardiometabolic risk factors studied and does not modify associations between fat measures and cardiometabolic risk factors. Longitudinal studies of the relationship between body fat and aerobic fitness with cardiovascular and kidney disease progression are warranted.

Sleep is critical for physical, emotional, and mental health. Health providers should be aware of sleep disorders to address patient-centered concerns. Patients with chronic kidney disease (CKD) or dialysis-dependent end-stage renal disease (ESRD) frequently report poor sleep quality and other sleep-related symptoms. Adult and pediatric patients with CKD often complain of snoring, difficulty falling asleep and maintaining sleep, excessive daytime sleepiness, unintentional daytime napping, and restless legs. Polysomnography studies often reveal a high frequency of obstructive sleep apnea in these patients. The high frequency of sleep disorders among those with CKD and ESRD is multifactorial, has an atypical presentation, and results in poor health, impaired daily functioning, poor quality of life, and reduced well-being. This chapter focuses on the most common sleep disorders and symptoms in CKD/ESRD and characterizes the extent to which these are reported. Finally, this chapter explores the diagnostic challenges and available management options.

Key Points Question Compared with other nursing homes, are private equity (PE)–owned nursing homes associated with better or worse coronavirus disease 2019 (COVID-19) outcomes? Findings In this cross-sectional study of 11 470 US nursing homes, there were no statistically significant differences in staffing levels, COVID-19 cases or deaths, or deaths from any cause between PE nursing homes and facilities with other ownership types. Compared with PE, all other ownership types were more likely to have at least a 1-week supply of N95 masks and medical gowns. Meaning In this study, PE-owned nursing homes performed comparably with for-profit and nonprofit nursing homes based on COVID-19 cases and deaths and deaths by any cause but had less personal protective equipment than other nursing homes., This cross-sectional study evaluates the comparative performance of private equity–owned nursing homes on coronavirus disease 2019 (COVID-19) outcomes., Importance It is not known whether nursing homes with private equity (PE) ownership have performed better or worse than other nursing homes during the coronavirus disease 2019 (COVID-19) pandemic. Objective To evaluate the comparative performance of PE-owned nursing homes on COVID-19 outcomes. Design, Setting, and Participants This cross-sectional study of 11 470 US nursing homes used the Nursing Home COVID-19 Public File from May 17, 2020, to July 2, 2020, to compare outcomes of PE-owned nursing homes with for-profit, nonprofit, and government-owned homes, adjusting for facility characteristics. Exposure Nursing home ownership status. Main Outcomes and Measures Self-reported number of COVID-19 cases and deaths and deaths by any cause per 1000 residents; possessing 1-week supplies of personal protective equipment (PPE); staffing shortages. Results Of 11 470 nursing homes, 7793 (67.9%) were for-profit; 2523 (22.0%), nonprofit; 511 (5.3%), government-owned; and 543 (4.7%), PE-owned; with mean (SD) COVID-19 cases per 1000 residents of 88.3 [2.1], 67.0 [3.8], 39.8 [7.6] and 110.8 [8.1], respectively. Mean (SD) COVID-19 deaths per 1000 residents were 61.9 [1.6], 66.4 [3.0], 56.2 [7.3], and 78.9 [5.9], respectively; mean deaths by any cause per 1000 residents were 78.1 [1.3], 91.5 [2.2], 67.6 [4.5], and 87.9 [4.8], respectively. In adjusted analyses, government-owned homes had 35.5 (95% CI, −69.2 to −1.8; P = .03) fewer COVID-19 cases per 1000 residents than PE-owned nursing homes. Cases in PE-owned nursing homes were not statistically different compared with for-profit and nonprofit facilities; nor were there statistically significant differences in COVID-19 deaths or deaths by any cause between PE-owned nursing homes and for-profit, nonprofit, and government-owned facilities. For-profit, nonprofit, and government-owned nursing homes were 10.5% (9.1 percentage points; 95% CI, 1.8 to 16.3 percentage points; P = .006), 15.0% (13.0 percentage points; 95% CI, 5.5 to 20.6 percentage points; P

Background and objectives Fatigue is a very common and debilitating symptom and identified by patients as a critically important core outcome to be included in all trials involving patients receiving hemodialysis. A valid, standardized measure for fatigue is needed to yield meaningful and relevant evidence about this outcome. This study validated a core patient-reported outcome measure for fatigue in hemodialysis. Design, setting, participants, & measurements A longitudinal cohort study was conducted to assess the validity and reliability of a new fatigue measure (Standardized Outcomes in Nephrology-Hemodialysis Fatigue [SONG-HD Fatigue]). Eligible and consenting patients completed the measure at three time points: baseline, a week later, and 12 days following the second time point. Cronbach α and intraclass correlation coefficient were calculated to assess internal consistency, and Spearman rho was used to assess convergent validity. Confirmatory factor analysis was also conducted. Hemodialysis units in the United Kingdom, Australia, and Romania participated in this study. Adult patients aged 18 years and over who were English speaking and receiving maintenance hemodialysis were eligible to participate. Standardized Outcomes in Nephrology-Hemodialysis, the Visual Analog Scale for fatigue, the 12-Item Short Form Survey, and Functional Assessment of Chronic Illness Therapy–Fatigue were used. Results In total, 485 participants completed the study across the United Kingdom, Australia, and Romania. Psychometric assessment demonstrated that Standardized Outcomes in Nephrology-Hemodialysis is internally consistent (Cronbach α =0.81–0.86) and stable over a 1-week period (intraclass correlation coefficient =0.68–0.74). The measure demonstrated convergence with Functional Assessment of Chronic Illness Therapy–Fatigue and had moderate correlations with other measures that assessed related but not the same concept (the 12-Item Short Form Survey and the Visual Analog Scale). Confirmatory factor analysis supported the one-factor model. Conclusions SONG-HD Fatigue seems to be a reliable and valid measure to be used in trials involving patients receiving hemodialysis.

BackgroundPatients with end-stage kidney disease (ESKD) treated with hemodialysis (HD) experience many distressing symptoms. One frequently reported symptom is insomnia. There are unique issues about HD treatments and schedules that disrupt regular sleep/wake routines and possibly contribute to the high severity of insomnia. Despite evidence for broad-ranging health effects of insomnia, very few clinical trials have tested the efficacy of treatments for HD patients. Cognitive-behavioral therapy for insomnia (CBT-I) is a recommended first-line therapy but largely inaccessible to HD patients in the United States, partly because they commit considerable amounts of time to thrice-weekly dialysis treatments. Another important reason could be the logistical and reimbursement challenges associated with providing behavioral health care at the dialysis center. CBT-I delivered by telehealth can overcome barriers to access, but its efficacy has never been rigorously tested for these patients. Pharmacotherapy is the most widely used treatment for insomnia; however, some drugs presently used are unsafe as they are associated with a higher risk for death for HD patients (benzodiazepines and zolpidem-like drugs). The efficacy and safety of other medications (trazodone) for the treatment of insomnia has never been tested for patients treated with HD.MethodsThis trial tests the short- and long-term comparative effectiveness of 6-week treatment with telehealth CBT-I, trazodone, or medication placebo. This will be accomplished with a randomized controlled trial (RCT) in which 126 participants treated with HD in community-based dialysis facilities with chronic insomnia will be assigned 1:1:1 to telehealth CBT-I, trazodone, or medication placebo, respectively; short-term effectiveness of each treatment arm will be determined at the end of 6-weeks of treatment and long-term effectiveness at 25-weeks. The primary and secondary patient-reported outcomes will be assessed with computer-based telephone interviewing by research scientists blinded to treatment assignment; additional secondary outcomes will be assessed by participant interview and actigraphy.DiscussionThis clinical RCT will provide the first evidence for the comparative effectiveness of two distinct approaches for treating chronic insomnia and other patient-reported outcomes for patients receiving maintenance HD.Trial registrationNCT03534284May 23, 2018.SLEEP-HD Protocol Version:1.3.4 (7/22/2020).

Introduction Patients receiving in-center maintenance hemodialysis (HD) spend a significant amount of time together. To date, little or no research has examined how these patients perceive and process other patients' medical events in and absences from their centers. We therefore undertook this qualitative study using semi-structured interviews to explore these phenomena from the patient perspective. Methods Patients at a suburban Pittsburgh HD center participated in semi-structured interviews in April to May 2011, reporting on their impressions of their relationships with other patients in the center; their experiences of witnessing clinical decompensations in the center; and their reactions to absences of fellow patients from the center. Trained coders developed a codebook and applied it to interview transcripts. Findings There were 17 participants, 47% women, 29% black, with median age 63 years. Almost every participant had witnessed other patients' medical events during HD. Three main themes emerged in analysis of interviews: (1) incomplete knowledge of many aspects of witnessed events and patient absences in the HD center; (2) a process of "filling in the blanks": Participants used their own past events and absences to help process other patients' events and absences and used other patients' events and absences to help process their own future events and absences; and (3) participants' broad support for HD center staff being able to share with other patients basic information about their whereabouts if they themselves are absent from the center. Discussion Witnessed medical events in and patients' absences from the HD center are not only common but are also important to patients, who struggle to process these events and absences due to limited information about what actually happened. Interventions, such as providing patients with more information, could improve patients' experience of witnessed events and fellow patients' absences and potentially impact other patient-centered outcomes.

Background The coronavirus disease 2019 (COVID-19) may have a negative effect on the mental and social health of patients with ESKD on chronic in-center hemodialysis (HD), who have a high burden of psychologic symptoms at baseline and unavoidable treatment-related COVID exposures. The goal of our study was to assess the effect of the COVID-19 pandemic on the psychosocial health of patients on chronic in-center HD. Methods Participants enrolled in the ongoing Technology Assisted Collaborative Care (TĀCcare) trial in Western Pennsylvania and New Mexico were approached for participation in a phone survey in May 2020. Data on the pandemic’s effects on participants’ physical and mental health, symptoms (such as anxiety, mood, loneliness, sleep, and stress), and food and housing security were collected. Results Surveys were completed by 49 participants (mean age 56 years; 53% men, 18% Black, 20% American Indian, and 22% Hispanic). Almost 80% of participants reported being moderately to extremely worried about the pandemic’s effects on their mental/emotional health and interpersonal relationships. More than 85% of the participants were worried about obtaining their dialysis treatments due to infection risk from close contact in the dialysis facility or during transportation. Despite this, 82% of participants reported being not at all/slightly interested in trying home dialysis as an alternative option. Overall, 27% of the participants had clinical levels of depressive symptoms but only 12% had anxiety meeting clinical criteria. About 33% of participants reported poor sleep quality over the last month. Perceived stress was high in about 30% of participants and 85% felt overwhelmed by difficulties with COVID-19, although 41% felt that things were fairly/very often going their way. Conclusions Our study provides preliminary insights into the psychosocial distress caused by the COVID-19 pandemic among a diverse cohort of patients receiving chronic HD who are participating in an ongoing clinical trial.

BACKGROUND: African Americans have lower rates of kidney transplantation (KT) compared to Whites, even after adjusting for demographic and medical factors. In this study, we examined whether racial disparity in KT wait-listing persists after adjusting for social determinants of health (e.g. cultural, psychosocial, knowledge). METHODS: We prospectively followed a cohort of 1055 patients who were evaluated for KT between 3/10–10/12 and followed through 8/18. Participants completed a semi-structured telephone interview shortly after their first KT evaluation appointment. We used Wilcoxon rank-sum and Pearson chi-square tests to examine race differences in the baseline characteristics. We then assessed racial differences in the probability of wait-listing while accounting for all predictors using cumulative incidence curves and Fine & Gray proportional subdistribution hazards models. RESULTS: There were significant differences in the baseline characteristics between non-Hispanic African Americans (AA) and non-Hispanic Whites (WH). AA were 25% less likely (95% confidence interval, 0.60–0.96) to be wait-listed than WH even after adjusting for medical factors and social determinants of health. In addition, being older, having lower income, public insurance, more comorbidities, and being on dialysis decreased the probability of wait-listing while having more social support and transplant knowledge increased the probability of wait-listing. CONCLUSION: Racial disparity in kidney transplant wait-listing persisted even after adjusting for medical factors and social determinants of health, suggesting the need to identify novel factors that impact racial disparity in transplant wait-listing. Developing interventions targeting cultural and psychosocial factors may enhance equity in access to transplantation.
