Project to Improve Communication About Serious Illness--Hospital Study: Comparative Effectiveness Trial (Trial 2)

The objective of this protocol is to test the effectiveness of a Jumpstart intervention on patient-centered outcomes for patients with chronic illness by ensuring that they receive care that is concordant with their goals over time, and across settings and providers. This study is particularly interested in understanding the effect of the intervention to improve quality of palliative care for patients with Alzheimer's disease and related dementias (ADRD) but will also include other common chronic, life-limiting illnesses. The specific aims are: 1) To evaluate the effectiveness of a survey-based patient/clinician Jumpstart guide compared to an EHR-based clinician Jumpstart guide for improving quality of care; the primary outcome is documentation of a goals-of-care discussion during the hospitalization. Secondary outcomes include: intensity of care (ICU use, ICU and hospital length of stay, costs of care during the hospitalization, and 30-day hospital readmission); patient- and surrogate/family-reported outcomes assessed by survey at 1 and 3 months after randomization including occurrence and quality of goals-of-care communication in the hospital, goal concordant care, psychological symptoms, quality of life, and palliative care needs. 2) To conduct a mixed-methods evaluation of the implementation of the intervention, guided by the RE-AIM framework for implementation science, incorporating quantitative evaluation of the intervention's reach and adoption, as well as qualitative analyses of interviews with participants, to explore barriers and facilitators to future implementation and dissemination.

Anticoagulation Strategies for Acute Venous Thromboembolism in Patients With End-Stage Renal Disease Using USRDS Data

Patients with end stage renal disease (ESRD) are at significantly increased risk of thrombosis and bleeding relative to those with normal renal function which makes anticoagulation particularly challenging. Further, ESRD patients undergoing initiation of anticoagulation for acute VTE are often kept in the hospital for heparin "bridging" which may lead to a protracted length-of-stay (LOS) and may place patients at risk for hospital-associated complications. The advent of direct oral anticoagulants (DOACs) has offered physicians choices in the management of venous thromboembolism (VTE). However, evidence suggests that rivaroxaban and dabigatran are associated with a higher risk of bleeding in ESRD patients. In contrast, research suggests that apixaban may be safer in patients with ESRD, and recent evidence suggests lower bleeding rates in ESRD patients treated for atrial fibrillation with apixaban compared to those treated with warfarin. However, to date, no large national cohort studies have examined the safety, effectiveness, and healthcare utilization of apixaban in patients with ESRD who have acute VTE. The investigators propose to use the Standard Analytic Files from the United States Renal Data System (USRDS) for years 2014 through 2018 to evaluate the safety, effectiveness, and healthcare utilization of ESRD patients initiated on apixaban compared to those initiated on warfarin (following heparin) to treat acute VTE.

Glucose Disorders Induced by Tacrolimus on Pre Transplantation Endstage Renal Disease Patients

Diabetes after kidney transplantation is a frequent complication, the incidence of which varies from 7 to 45% depending on the studies and on the diagnostic criteria used. Post-transplant diabetes is an early complication, most often occurring in the first month after transplantation. In addition to the additional health costs generated by the appearance of post-transplant diabetes, the risk of graft loss is increased by 60% and the overall mortality risk by 90%. Similarly, the development of glucose intolerance after transplantation is associated with higher mortality. Tacrolimus treatment is therefore currently one of the most important risk factors for diabetes at the time of transplantation. Indeed, several in vitro and in vivo animal studies have shown that tacrolimus alters pancreatic endocrine function. In the final stage, this cellular toxicity leads to diabetes, most often diagnosed on the rise in capillary or venous blood sugar levels after transplantation. This diabetes often requires hypoglycemic treatment with insulin or oral anti-diabetic drugs. for a variable period. The pro-diabetogenic effect of tacrolimus is sometimes irreversible, justifying preventive treatment. No clinical studies have looked at "sub-clinical" changes in insulin secretion or insulin resistance under tacrolimus prior to the onset of diabetes. The static indices HOMA-?% and HOMA-IR (Homeostasis Model Accessment of insulin resistance) make it possible to estimate insulin secretion and insulin resistance in fasting patients respectively, while the oral glucose disposition index (IDO) makes it possible to study insulin secretion and action dynamically (after a 75 g glucose load), and are calculated as follows: HOMA IR= Fasting blood glucose (mmol/L) x Fasting insulin (mU/L)/ 22.5 HOMA?% = 20 x fasting insulinemia (mU/L) / fasting plasma glucose (mmol/L) - 3.5 IDO = (delta insulinemia T30-T0/ delta blood glucose T30-T0)/insulinemia T0 These indices have already been studied in dialysis patients (diabetic and non-diabetic) and may allow a more detailed study of pancreatic response and insulin resistance under tacrolimus in patients prior to renal transplantation. Determining the "pancreatic response" to tacrolimus in patients prior to transplantation would prevent diabetes by adapting immunosuppressive treatment and post-transplant screening modalities in the event of pre-transplant subclinical abnormalities identified in our study. The development of tacrolimus-induced diabetes in pre-transplantation in our study will be a contraindication to tacrolimus at the time of transplantation and ciclosporin therapy will be preferred.

Quality of Life of Frail Aged Patients in Incremental Hemodialysis

End stage renal disease (ESRD) is a major public health problem. The dialysis population is aging. As a result we observe a high prevalence of frailty among dialysis patients (ranges from 3 to 10 fold higher than in the comparably aged general public). Frailty is a medical syndrome characterized by diminished strength, endurance, and reduced physiologic function that increases an individual's vulnerability for developing increased dependency and/or death. Without systematic approach it is difficult for physicians to detect frailty phenotype which however might be reversible or attenuated by interventions. Fried et al. developed a frailty phenotype consisting of 3 or more of: unintentional weight loss, exhaustion, physical inactivity, slow gait speed, and weak grip strength. The primary care of hemodialysis patient is often supported by the nephrologist. Identification of frailty is integrated into the primary care setting as one of the steps necessary for the overall assessment of the person and planning to formal prevention interventions in an individualized care plan. Thrice-weekly hemodialysis (HD) schedules are the standard default hemodialysis prescription in Western countries, imposed in the 70s. For incremental HD, the weekly dose of dialysis is based on variety of clinical factors such as residual kidney function, volume status, cardiovascular symptoms, potassium level, nutritional status and, comorbid conditions. Incremental HD scheme generally starts with 2 weekly sessions and then periodic monitoring of criteria mentioned above are used to determine the timing for increasing dialysis dose and frequency to 3 weekly sessions. An approach that integrates systematic frailty phenotype assessment by nephrologists and individualized incremental HD therapy can be beneficial within the first year of HD. It could optimize health-related quality of life and other pertinent outcomes without affecting negatively the quality of dialysis. The purpose of this study is to evaluate for frail aged incidents hemodialysis patients the impact of implementation of an incremental HD on HRQoL compared to conventional HD.

International (Pediatric) Peritoneal Biobank

Within few years the peritoneal membrane of adult peritoneal dialysis (PD) patients undergoes substantial morphological transformation, including progressive fibrosis, vasculopathy and neoangiogenesis. Ultrafiltration capacity steadily declines and ultimately results in PD failure. In children, peritoneal biopsies demonstrating PD associated alterations have not yet been obtained. They, however, should be particularly informative, since secondary tissue and vascular pathology related to ageing or diabetes is absent. An international, prospective peritoneal membrane biopsy study in children on PD will therefore be performed. Biopsies will be obtained at time of PD catheter insertion, on occasion of intercurrent abdominal surgery (e.g. hernia repair, catheter exchange) and at time of renal transplantation. Quantitative histomorphometry and tissue protein expression analyses will be correlated with time integrated PD treatment modalities and functional characteristics as well as inflammatory and cardiovascular comorbidity surrogate parameter. Blood will be obtained during clinical routine sampling. Biopsies will be obtained during clinically indicated operations, without substantially increasing operation time and associated surgical risks. The detailed histomorphometry of the PD membrane will give additional information, potentially impacting on the individual PD regime. 3/2018: The analyses of the pediatric PD biopsy demonstrated early and major transformation of the peritoneal membrane with neutral pH low GDP fluids, and significant vasculopathy already in children with CKD stage 5, further progressing with PD. The underlying mechanisms are partly understood, only. In view of these major findings and the numerous open questions, collection of biosamples will be continued in children and also in adult PD patients. The following questions will be addressed: Molecular counterparts of peritoneal semi-permeability, solute and water transport (beyond AQP1), pathomechanisms and molecular and functional impact of peritoneal transformation with low and high GDP fluids, and the respective pathomechanisms and molecular and functional impact of vascular disease in CKD and with different PD fluids. The impact of renal transplantation following PD will be assessed in a subgroup of patients with tenckhoff catheter removal several weeks after transplantation and a functioning graft.
