Abstract
BACKGROUND For patients who initiate dialysis during a hospital admission and continue to require dialysis after discharge, outpatient dialysis management could be improved by better understanding the future likelihood of recovery to dialysis independence and the competing risk of death. METHODS We derived and validated linked models to predict the subsequent recovery to dialysis independence and death within 1 year of hospital discharge using a population-based cohort of 7657 patients in Ontario, Canada. Predictive variables included age, comorbidities, length of hospital admission, intensive care status, discharge disposition, and prehospital admission eGFR and random urine albumin-to-creatinine ratio. Models were externally validated in 1503 contemporaneous patients from Alberta, Canada. Both models were created using proportional hazards survival analysis, with the "Recovery Model" using Fine-Gray methods. Probabilities generated from both models were used to develop 16 distinct "Recovery and Death in Outpatients" (ReDO) risk groups. RESULTS ReDO risk groups in the derivation group had significantly distinct 1-year probabilities for recovery to dialysis independence (first quartile: 10% [95% confidence interval (CI), 9% to 11%]; fourth quartile: 73% [70% to 77%]) and for death (first quartile: 12% [11% to 13%]; fourth quartile: 46% [43% to 50%]). In the validation group, model discrimination was modest (c-statistics [95% CI] for recovery and for death quartiles were 0.70 [0.67 to 0.73] and 0.66 [0.62 to 0.69], respectively), but calibration was excellent (integrated calibration index [95% CI] was 7% [5% to 9%] and 4% [2% to 6%] for recovery and death, respectively). CONCLUSIONS The ReDO models generated accurate expected probabilities of recovery to dialysis independence and death in patients who continued outpatient dialysis after initiating dialysis in hospital.

Assessing the Delivery of Coordinated Care to Patients with Advanced Chronic Kidney Disease in Ontario, Canada: A Survey of Patients and Healthcare Professionals. Int J Integr Care 2021; 21:30. [PMID: 34220394 PMCID: PMC8231462 DOI: 10.5334/ijic.5587] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/04/2022] Open
Abstract
Introduction: Patients with advanced Chronic Kidney Disease (CKD) have complex health needs, and thus require care that is coordinated across professionals and organizations. This study aimed to describe the extent of coordinated care delivery for patients with advanced CKD from the perspectives of both patients and healthcare professionals. Methods: The Coordination Scale of the Patient Assessment of Chronic Illness Care (PACIC-26) survey was administered to a random sample of 14,257 patients on maintenance dialysis or receiving care in end-stage kidney disease preparation clinics in Ontario, Canada. A five-item survey was administered to 596 multidisciplinary nephrology professionals. Results: Among the 1,925 patient respondents, 67% reported they had been referred to an allied health professional; 19% had been encouraged to attend programs in the community; and 34% had been told how their visits with other types of doctors helped their treatment (% reporting “always” or “most of the time”). Patient responses were significantly different by treatment modality/setting, but not by gender or geographic location of treatment facility. Among the 276 professional respondents, 37% reported their patients’ care was well-coordinated across settings; 56% reported participating in interdisciplinary care planning discussions; and 53% reported they are aware of appropriate home and community services to support their patients (% reporting “always” or “most of the time”). Conclusion: The results suggest that care for patients with advanced CKD in Ontario is not consistently coordinated. Healthcare professionals may enhance patient perceptions of coordinated care through explicit communication with patients about how the professionals they see and treatments or services they receive influence their overall health and well-being. At a systems level, there is a need to improve professional awareness of and linkages to home- and community-based services.

Abstract
The recently published 2020 International Society for Peritoneal Dialysis (ISPD) practice recommendations regarding prescription of high-quality goal-directed peritoneal dialysis differ fundamentally from previous guidelines that focused on "adequacy" of dialysis. The new ISPD publication emphasizes the need for a person-centered approach with shared decision making between the individual performing peritoneal dialysis and the clinical care team while taking a broader view of the various issues faced by that individual. Cognizant of the lack of strong evidence for the recommendations made, they are labeled as "practice points" rather than being graded numerically. This commentary presents the views of a work group convened by the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) to assess these recommendations and assist clinical providers in the United States in interpreting and implementing them. This will require changes to the current clinical paradigm, including greater resource allocation to allow for enhanced services that provide a more holistic and person-centered assessment of the quality of dialysis delivered.

Abstract
Background: Despite evidence that advance care planning (ACP) benefits patients with serious illnesses, there is a dearth of information about "who" is referred for palliative care (PC) consultation, the rate of PC consultation, and the outcomes of referrals in patients with advanced chronic kidney disease/end-stage kidney disease (aCKD/ESKD). Objectives: (1) To describe patient characteristics associated with PC consultations and (2) to determine the frequency and outcome of PC consultation on documented ACP discussions for patients with aCKD/ESKD. Methodology/Design: This is retrospective observational electronic health record cohort review. Settings: University of Virginia (UVA) hospital, clinics, and dialysis units. Participants: Patients were studied along two time intervals. Time period January 1, 2015 to June 30, 2017 included all patients admitted to UVA during that time period with estimated glomerular filtration rate (eGFR) <60 mL/minute. Time period January 1, 2018 to March 31, 2019 included two cohorts: patients with eGFR <15 mL/minute who had died during study period excluding those who withdrew from dialysis and those who were dialysis dependent and withdrew from dialysis. Results: Aside from higher rates of PC consultation in patients with heart failure, none of the demographic and comorbidity data studied affected whether or not a patient is referred to PC in patients with aCKD/ESKD. PC consultation rates were low among all patients studied: 14.7% in patients with eGFR <60 mL/minute, 28.9% in dialysis patients withdrawing from dialysis, and 57.1% in terminally ill patients with eGFR <15 mL/minute. In all cohorts, PC consultations were associated with improved ACP. Conclusion: PC consultation is significantly associated with better end-of-life outcomes with more completion of ACP and hospice referral in patients with aCKD/ESKD. PC consultation rates remain low. Even in terminally ill patients with more aCKD, >40% were never seen by PC. Until policies and curricula better prepare nephrologists to independently address ACP, collaboration between nephrologists and PC specialists is recommended.

Abstract
Person-centered care has become a dominant paradigm in modern health care. It needs to be applied to people with end-stage kidney disease considering the initiation of dialysis and to peritoneal dialysis (PD) prescription and care delivery. It is relevant to their decisions about goals of care, transplantation, palliative care, and discontinuation of dialysis. It is also relevant to decisions about how PD is delivered, including options such as incremental PD. Shared decision-making is the essence of this process and needs to become a standard principle of care. It requires engagement, education, and empowerment of patients. Patient-reported outcomes and patient-reported experience are also central to person-centered care in PD.

Abstract
Background Only a small number of patients have utilized the home-based end-of-life care service in Shanghai that has been offered since 2012. This study explores how home-based end-of-life care is delivered in community health service centers in Shanghai and examines the difficulties in the delivery of the care. Methods This was a qualitative study in which data were collected from interviews and analyzed using qualitative content analysis. Nineteen health care providers with experience in delivering home-based end-of-life care in 12 community health service centers were recruited. The interviews were conducted between August 2018 and February 2019. Results Four themes emerged from the interviews: (i) Patients under home-based end-of-life care: Patients receiving the care were cancer patients with less than 1 year of life expectancy. The criteria for patients were broad. (ii) Service structure: The service was delivered regularly by the physicians and nurses using the approaches of home visits and/or telephone follow-ups. (iii) Service process: The service consisted of multiple components, including monitoring the patient’s condition, managing the patient’s symptoms, giving daily care instructions, performing nursing procedures, and giving psychological support. However, most of the care focused on monitoring the patients and managing their physical discomfort. (iv) Difficulties in delivering care: Being unable to provide the service and feeling powerless when facing psycho-spiritual problems were the two major difficulties. Three factors contributed to the suspension of the service: The gap between the service and the needs of the patients, a lack of patients, and low work motivation. The demand that the truth be concealed from the families and their attitude of avoiding talking about death were the key factors of the failure of psycho-spiritual care. Conclusions Several issues should be addressed before the service can be further developed, including fully understanding the needs and preferences of local patients and their families, securing more financial support and a better supply of drugs, delivering better training for staff, and ensuring greater rewards for individuals and institutions providing the service.

Abstract
BACKGROUND Life expectancy in patients with end-stage kidney disease treated with hemodialysis (HD) is limited, and as such, the presence of an advanced care directive (ACD) may improve the quality of death as experienced for patients and families. Strategies to discuss and implement ACDs are limited with little being known about the status of Do Not Resuscitate (DNR) orders in the Canadian HD population. OBJECTIVES Using data from the Dialysis Outcomes and Practice Patterns Study (DOPPS), we set out to (1) examine the variability in DNR orders across Canada and its largest province, Ontario and (2) identify clinical and functional status measures associated with a DNR order. DESIGN We conducted a retrospective cohort study using data from the DOPPS Canada Phase 4 to 6 from 2009 to 2017. SETTING DOPPS facilities in Canada. PATIENTS All adults (>18 years) who initiated chronic HD with a documented ACD were included. MEASUREMENTS ACD and DNR orders. METHODS Descriptive statistics were compared for baseline characteristics (demographics, comorbidities, medications, facility characteristics, and patient functional status) and DNR status. The crude proportion of patients per facility with a DNR order was calculated across Canada and Ontario. Functional status was determined by activities of daily living and components of the Kidney Disease Quality of Life (KDQOL)-validated questionnaire. We used generalized estimating equations (GEEs) to create sequential multivariable models (demographics, comorbidities, and functional status) of variables associated with DNR status. RESULTS A total of 1556 (96% of total) patients treated with HD had a documented ACD and were included. A total of 10% of patients had a DNR order. The crude variation of DNR status differed considerably across facilities within Canada, between Ontario and non-Ontario, and within Ontario (interprovince variation = 6.3%-17.1%, Ontario vs non-Ontario = 8.2% vs 11.7%, intraprovincial variation [Ontario] = 1%-26%). Patients with a DNR order were more commonly older, white, with cardiac comorbidities, with less or shorter predialysis care compared with those without a DNR order. Patients with a DNR order reported lower energy, more difficulty with transfers, meal preparation, household tasks, and financial management. In a multivariate model, age, cardiac disease, stroke, dialysis duration, and intradialytic weight gain were associated with DNR status. LIMITATIONS Relatively small number of events or measures in certain categories. CONCLUSIONS A large inter- and intraprovincial (Ontario) variation was observed regarding DNR orders across Canada highlighting areas for potential quality improvement. While functional status did not appear to have a bearing on the presence of a DNR order, the presence of various comorbidities was associated with the presence of a DNR order.
