    Abstract Background Kidney failure requiring dialysis is associated with poor health outcomes and health-related quality of life (HRQL). Patient-reported outcome measures (PROMs) capture symptom burden, level of functioning and other outcomes from a patient perspective, and can support clinicians to monitor disease progression, address symptoms, and facilitate patient-centered care. While evidence suggests the use of PROMs in clinical practice can lead to improved patient experience in some settings, the impact on patients’ health outcomes and experiences is not fully understood, and their cost-effectiveness in clinical settings is unknown. This study aims to fill these gaps by evaluating the effectiveness and cost-effectiveness of routinely measuring PROMs on patient-reported experience, clinical outcomes, HRQL, and healthcare utilization. Methods The EMPATHY trial is a pragmatic multi-centre cluster randomized controlled trial that will implement and evaluate the use of disease-specific and generic PROMs in three kidney care programs in Canada. In-centre hemodialysis units will be randomized into four groups, whereby patients: 1) complete a disease-specific PROM; 2) complete a generic PROM; 3) complete both types of PROMs; 4) receive usual care and do not complete any PROMs. While clinical care pathways are available to all hemodialysis units in the study, for the three active intervention groups, the results of the PROMs will be linked to treatment aids for clinicians and patients. The primary outcome of this study is patient-provider communication, assessed by the Communication Assessment Tool (CAT). Secondary outcomes include patient management and symptoms, use of healthcare services, and the costs of implementing this intervention will also be estimated. The present protocol fulfilled the Standard Protocol Items: Recommendations for Intervention Trials (SPIRIT) checklist. Discussion While using PROMs in clinical practice is supported by theory and rationale, and may engage patients and enhance their role in decisions regarding their care and outcomes, the best approach of their use is still uncertain. It is important to rigorously evaluate such interventions and investments to ensure they provide value for patients and health systems. Trial registration Protocol version (1.0) and trial registration data are available on www.clinicaltrials.gov , identifier: NCT03535922 , registered May 24, 2018.

    A comparison of temporal artery thermometers with internal blood monitors to measure body temperature during hemodialysis
    (2018-06-14) Lunney, Meaghan; Tonelli, Bronwyn; Lewis, Rachel; Wiebe, Natasha; Thomas, Chandra; MacRae, Jennifer; Tonelli, Marcello
    Abstract Background Thermometers that measure core (internal) body temperature are the gold standard for monitoring temperature. Despite that most modern hemodialysis machines are equipped with an internal blood monitor that measures core body temperature, current practice is to use peripheral thermometers. A better understanding of how peripheral thermometers compare with the dialysis machine thermometer may help guide practice. Methods The study followed a prospective cross-sectional design. Hemodialysis patients were recruited from 2 sites in Calgary, Alberta (April – June 2017). Body temperatures were obtained from peripheral (temporal artery) and dialysis machine thermometers concurrently. Paired t-tests, Bland-Altman plots, and quantile-quantile plots were used to compare measurements from the two devices and to explore potential factors affecting temperature in hemodialysis patients. Results The mean body temperature of 94 hemodialysis patients measured using the temporal artery thermometer (36.7 °C) was significantly different than the dialysis machine thermometer (36.4 °C); p < 0.001. The mean difference (0.27 °C) appeared to be consistent across average temperature (range: 35.8–37.3 °C). Conclusions Temperature measured by the temporal artery thermometer was statistically and clinically higher than that measured by the dialysis machine thermometer. Using the dialysis machine to monitor body temperature may result in more accurate readings and is likely to reduce the purchasing and maintenance costs associated with manual temperature readings, as well as easing the workload for dialysis staff.

    Care and Outcomes for Older Adults with Advanced Chronic Kidney Disease
    (2017) Helen, Tam-Tham; Hemmelgarn, Brenda; Fruetel, Karen; King-Shier, Kathryn; Quinn, Robert; Thomas, Chandra
    The prevalence of older adults with advanced chronic kidney disease (CKD) is increasing globally, although optimal treatment remains uncertain. We examined in this thesis survival outcomes for older adults with kidney failure treated and not treated with dialysis. We also sought to identify barriers and facilitators to optimal conservative (non-dialysis) care for older adults with kidney failure managed by primary care physicians. We conducted three studies: a population-based retrospective cohort study using administrative and laboratory data to compare survival outcomes between dialysis and non-dialysis treatment; a qualitative descriptive study to explore primary care physician experiences when providing conservative care to older adults with kidney failure; and a cross-sectional population-based survey study within Alberta, Canada, to quantify results from the previous qualitative study. These last two studies formed a sequential exploratory mixed methods program of work to identify barriers and facilitators to community-based conservative care. We found that compared to non-dialysis care, dialysis was associated with a reduced risk of all-cause mortality but only within the first three years following onset of kidney failure. Conservative care for older adults is commonly provided by primary care physicians; however, they face substantial barriers to optimal care. Primary care physicians also expressed a need for resources including telephone access to nephrology or conservative care expertise, better access to conservative care clinics, and improved ability to appropriately co-manage patients with nephrologists. Research in conservative care has previously focused on patients with advanced CKD referred to nephrology. However, conservative care and outcomes among older adults not referred to nephrology is largely unknown. This thesis examined clinical care and outcomes through a wider perspective. To foster clinical impact we worked closely from conceptualization to dissemination stages with key stakeholders in Alberta including the Southern Alberta Conservative Management Program, the Conservative Kidney Management Pathway Steering Committee, the Kidney Health Strategic Clinical Network, and the Alberta College of Family Physicians. Our findings contributed to development of a conservative kidney management clinical care pathway and province-wide telephone access for primary care physicians to directly contact nephrologists and conservative care specialists.

    Patient and provider experience and perspectives of a risk-based approach to multidisciplinary chronic kidney disease care: a mixed methods study
    (2019-03-29) Smekal, Michelle D; Tam-Tham, Helen; Finlay, Juli; Donald, Maoliosa; Thomas, Chandra; Weaver, Robert G; Quinn, Robert R; Tam, Kin; Manns, Braden J; Tonelli, Marcello; Bello, Aminu; Tangri, Navdeep; Hemmelgarn, Brenda R
    Abstract Background The Kidney Failure Risk Equation (KFRE) predicts risk of progression to kidney failure and is used to guide clinical decisions for patients with chronic kidney disease (CKD). Methods The KFRE was implemented to guide access to multidisciplinary care for CKD patients in Alberta, Canada, based on their 2-year risk of kidney failure. We used a mixed methods approach to investigate patients’ and providers’ perspectives and experiences 1 year following KFRE implementation. We conducted post-implementation interviews with multidisciplinary clinic providers and with low-risk patients who transitioned from multidisciplinary to general nephrology care. We also administered pre- and post-implementation patient care experience surveys, targeting both low-risk patients discharged to general nephrology and high-risk patients who remained in the multidisciplinary clinic, and provider job satisfaction surveys. Results Twenty-seven interviews were conducted (9 patients, 1 family member, 17 providers). Five categories were identified among patients and providers: targeted care; access to resources outside the multidisciplinary clinics; self-efficacy; patient reassurance and reduced stress; and transition process for low-risk patients Two additional categories were identified among providers only: anticipated concerns and job satisfaction. Patients and providers reported that the risk-based approach allowed the clinic to target care to those most likely to experience kidney failure and most likely to benefit from multidisciplinary care. While some participants indicated the risk-based model enhanced the sustainability of the clinics, others expressed concern that care for low-risk patients discharged from multidisciplinary care, or those now considered ineligible, may be inadequate. Overall, 413 patients completed the care experience survey and 73 providers completed the workplace satisfaction survey. The majority of patients were satisfied with their care in both periods with no overall differences. When considering the responses “Always” and “Often” together versus not, there were statistically significant improvements in domains of access to care, caring staff, and safety of care. There were no differences in healthcare providers’ job satisfaction following KFRE implementation. Conclusions Patients and healthcare providers reported that the risk-based approach improved the focus of the multidisciplinary CKD clinics by targeting patients at highest risk, with survey results suggesting no difference in patient care experience or healthcare provider job satisfaction.
