Medications Used Routinely in Primary Care to be Dose-Adjusted or Avoided in People With Chronic Kidney Disease: Results of a Modified Delphi Study.

Background: Chronic kidney disease (CKD) affects up to 18% of those over the age of 65 years. Potentially inappropriate medication prescribing in people with CKD is common. Objectives: Develop a pragmatic list of medications used in primary care that required dose adjustment or avoidance in people with CKD, using a modified Delphi panel approach, followed by a consensus workshop. Methods: We conducted a comprehensive literature search to identify potential medications. A group of 17 experts participated in a 3-round modified Delphi panel to identify medications for inclusion. A subsequent consensus workshop of 8 experts reviewed this list to prioritize medications for the development of point-of-care knowledge translation materials for primary care. Results: After a comprehensive literature review, 59 medications were included for consideration by the Delphi panel, with a further 10 medications added after the initial round. On completion of the 3 Delphi rounds, 66 unique medications remained, 63 requiring dose adjustment and 16 medications requiring avoidance in one or more estimated glomerular filtration rate categories. The consensus workshop prioritized this list further to 24 medications that must be dose-adjusted or avoided, including baclofen, metformin, and digoxin, as well as the newer SGLT2 inhibitor agents. Conclusion and Relevance: We have developed a concise list of 24 medications commonly used in primary care that should be dose-adjusted or avoided in people with CKD to reduce harm. This list incorporates new and frequently prescribed medications and will inform an updated, easy to access source for primary care providers.

Identifying Needs for Self-management Interventions for Adults With CKD and Their Caregivers: A Qualitative Study.

RATIONALE & OBJECTIVE: Fostering the ability of patients to self-manage their chronic kidney disease (CKD), with support from caregivers and providers, may slow disease progression and improve health outcomes. However, little is known about such patients' needs for self-management interventions. We aimed to identify and describe the needs of adults with CKD and informal caregivers for CKD self-management support. STUDY DESIGN: Descriptive qualitative study using semi-structured interviews and focus groups. SETTING & PARTICIPANTS: 6 focus groups (37 participants) and 11 telephone interviews with adults with CKD (stages 1-5, not on renal replacement therapy) and informal caregivers from across Canada. ANALYTIC APPROACH: Thematic analysis. RESULTS: 3 major themes were identified: (1) empowerment through knowledge (awareness and understanding of CKD, diet challenges, medication and alternative treatments, attuning to the body, financial implications, mental and physical health consequences, travel and transportation restrictions, and maintaining work and education), (2) activation through information sharing (access, meaningful and relevant, timing, and amount), and (3) tangible supports for the health journey (family, community, and professionals). LIMITATIONS: Participants were primarily white, educated, married, and English speaking, which limits generalizability. CONCLUSIONS: There are opportunities to enhance CKD self-management support by addressing knowledge pertinent to living well with CKD and priority areas for sharing information and providing tangible support. Future efforts may consider the development of innovative CKD self-management support interventions based on the diverse patient and caregiver needs identified in this study.

Approach to the detection and management of chronic kidney disease: What primary care providers need to know.

OBJECTIVE: To help primary care providers, both family physicians and nurse practitioners, identify, detect, and manage patients with and at risk of chronic kidney disease (CKD), as well as outline criteria for appropriate referral to nephrology. SOURCES OF INFORMATION: Published guidelines on the topic of CKD and its comorbidities were reviewed. A MEDLINE search was conducted using the MeSH terms chronic renal insufficiency, family practice, and primary health care. The search was limited to reviews and articles in English. The search covered all relevant articles from 2006 to the present. MAIN MESSAGE: The KidneyWise clinical tool kit, created by the Ontario Renal Network and available at www.kidneywise.ca, provides evidence-informed, practical guidance to primary care providers on the diagnosis and management of CKD. A component of this tool is an algorithm that offers a step-by-step approach to diagnosing and managing CKD. This resource will help empower providers to identify those at high risk of this condition, order appropriate diagnostic tests, help prevent further disease progression, and reduce comorbid cardiovascular risk in patients with CKD. CONCLUSION: Most patients with CKD can be managed in primary care. Serial follow-up is essential to identify patients at high risk of progression to advanced stages of CKD, including end-stage renal disease. Primary care providers must continue to work together with local nephrologists to improve the lives of those living with CKD.

Evaluation of a mentorship program to support chronic kidney disease care.

PROBLEM ADDRESSED: Primary care providers (PCPs) are ideally situated to detect and manage patients with chronic kidney disease (CKD), but they could use more support from nephrologists to accomplish this. OBJECTIVE OF PROGRAM: To improve early detection and management of CKD in primary care, and improve referrals to nephrologists through education and greater partnership between nephrologists and PCPs. PROGRAM DESCRIPTION: Nephrologists provided mentorship to PCPs in Ontario through a collaborative relationship. Nephrologists provided PCPs with educational orientation sessions and need-based advice on patient cases. CONCLUSION: Primary care providers with more than 5 years of experience were more likely to use the program. Primary care providers expressed high satisfaction with the program and reported that it was effective in supporting routine CKD screening efforts, management of early CKD, appropriate referrals, and building a collaborative relationship with nephrologists.

Canadian Society of Nephrology commentary on the KDIGO clinical practice guideline for CKD evaluation and management.

We congratulate the KDIGO (Kidney Disease: Improving Global Outcomes) work group on their comprehensive work in a broad subject area and agreed with many of the recommendations in their clinical practice guideline on the evaluation and management of chronic kidney disease. We concur with the KDIGO definitions and classification of kidney disease and welcome the addition of albuminuria categories at all levels of glomerular filtration rate (GFR), the terminology of G categories rather than stages to describe level of GFR, the division of former stage 3 into new G categories 3a and 3b, and the addition of the underlying diagnosis. We agree with the use of the heat map to illustrate the relative contributions of low GFR and albuminuria to cardiovascular and renal risk, though we thought that the highest risk category was too broad, including as it does people at disparate levels of risk. We add an albuminuria category A4 for nephrotic-range proteinuria and D and T categories for patients on dialysis or with a functioning renal transplant. We recommend target blood pressure of 140/90mm Hg regardless of diabetes or proteinuria, and against the combination of angiotensin receptor blockers with angiotensin-converting enzyme inhibitors. We recommend against routine protein restriction. We concur on individualization of hemoglobin A1c targets. We do not agree with routine restriction of sodium intake to <2g/d, instead suggesting reduction of sodium intake in those with high intake (>3.3g/d). We suggest screening for anemia only when GFR is <30mL/min/1.73m(2). We recognize the absence of evidence on appropriate phosphate targets and methods of achieving them and do not agree with suggestions in this area. In drug dosing, we agree with the recommendation of using absolute clearance (ie, milliliters per minute), calculated from the patient's estimated GFR (which is normalized to 1.73m(2)) and the patient's actual anthropomorphic body surface area. We agree with referral to a nephrologist when GFR is <30mL/min/1.73m(2) (and for many other scenarios), but suggest urine albumin-creatinine ratio > 60mg/mmol or proteinuria with protein excretion > 1g/d as the referral threshold for proteinuria.

A Proposed Curricular Framework for an Interprofessional Approach to Deprescribing.

Deprescribing involves reducing or stopping medications that are causing more harm than good or are no longer needed. It is an important approach to managing polypharmacy, yet healthcare professionals identify many barriers. We present a proposed pre-licensure competency framework that describes essential knowledge, teaching strategies, and assessment protocols to promote interprofessional deprescribing skills. The framework considers how to involve patients and care partners in deprescribing decisions. An action plan and example curriculum mapping exercise are included to help educators assess their curricula, and select and implement these concepts and strategies within their programs to ensure learners graduate with competencies to manage increasingly complex medication regimens as people age.

A patient decision aid for mild asthma: Navigating a new asthma treatment paradigm.

INTRODUCTION: In mild asthma, as-needed budesonide-formoterol offers similar protection from severe exacerbations as daily inhaled corticosteroids (ICS), with lower ICS exposure but slightly increased symptoms. We sought to develop an electronic decision aid to guide discussions about the pros and cons of these first-line options, while identifying and integrating user preferences. METHODS: Following International Patient Decision Aid Standards, we created a mild asthma decision aid prototype comparing convenience, clinical outcomes, cumulative ICS dose exposure, costs, and side-effects of each option. After face validation, the prototype was iteratively adapted through rapid-cycle development. Each cycle consisted of a patient focus group and a primary care physician interview. We made user preference-based improvements after each round, until reaching a pre-set stopping criterion (no new critical issues identified). We then performed a summative qualitative content analysis. RESULTS: Over 5 cycles, we recruited 21 asthma patients (12/21 women, 10/21 ≥ 60 years old) and 5 physicians. Serial changes included simplification and reduction of text and reading level, inclusion of an ICS "myths" section and elaboration of patient-friendly infographics for numerical comparisons. User preferences fell within Content, Format, and tool use Process themes. In response to decision-making preferences, we created a complementary one-page conversation aid for patient-provider use at the point-of-care. CONCLUSIONS: We present preference-based electronic patient decision and conversation aids for treatment of mild asthma. Our user preference analyses offer useful insights for development of such tools in other chronic diseases. These tools now require integration into point-of-care workflows for measurement of real-world uptake and impact.

An eHealth self-management intervention for adults with chronic kidney disease, My Kidneys My Health: a mixed-methods study.

BACKGROUND: There is limited research of electronic tools for self-management for patients with chronic kidney disease (CKD). We sought to evaluate participant engagement, perceived self-efficacy and website usage in a preliminary evaluation of My Kidneys My Health, a patient-facing eHealth tool in Canada. METHODS: We conducted an explanatory sequential mixed-methods study of adults with CKD who were not on kidney replacement therapy and who had access to My Kidneys My Health for 8 weeks. Outcomes included acceptance (measured by the Technology Acceptance Model), self-efficacy (measured by the Chronic Disease Self-Efficacy Scale [CDSES]) and website usage patterns (captured using Google Analytics). We analyzed participant interviews using qualitative content analysis. RESULTS: Twenty-nine participants with CKD completed baseline questionnaires, of whom 22 completed end-of-study questionnaires; data saturation was achieved with 15 telephone interviews. Acceptance was high, with more than 70% of participants agreeing or strongly agreeing that the website was easy to use and useful. Of the 22 who completed end-of-study questionnaires, 18 (82%) indicated they would recommend its use to others and 16 (73%) stated they would use the website in the future. Average scores for website satisfaction and look and feel were 7.7 (standard deviation [SD] 2.0) and 8.2 (SD 2.0) out of 10, respectively. The CDSES indicated that participants gained an increase in CKD information. Interviewed participants reported that the website offered valuable information and interactive tools for patients with early or newly diagnosed CKD, or for those experiencing changes in health status. Popular website pages and interactive features included Food and Diet, What is CKD, My Question List and the Depression Screener. INTERPRETATION: Participants indicated that the My Kidneys My Health website provided accessible content and tools that may improve self-efficacy and support in CKD self-management. Further evaluation of the website's effectiveness in supporting self-management among a larger, more heterogenous population is warranted.

Impact of quality improvement initiatives to improve CKD referral patterns: a systematic review protocol.

INTRODUCTION: Chronic kidney disease (CKD) is a global-health problem. A significant proportion of referrals to nephrologists for CKD management are early and guideline-discordant, which may lead to an excess number of referrals and increased wait-times. Various initiatives have been tested to increase the proportion of guideline-concordant referrals and decrease wait times. This paper describes the protocol for a systematic review to study the impacts of quality improvement initiatives aimed at decreasing the number of non-guideline concordant referrals, increasing the number of guideline-concordant referrals and decreasing wait times for patients to access a nephrologist. METHODS AND ANALYSIS: We developed this protocol by using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols (2015). We will search the following empirical electronic databases: MEDLINE, Embase, Cochrane Library, CINAHL, Web of Science, PsycINFO and grey literature for studies designed to improve guideline-concordant referrals or to reduce unnecessary referrals of patients with CKD from primary care to nephrology. Our search will include all studies published from database inception to April 2021 with no language restrictions. The studies will be limited to referrals for adult patients to nephrologists. Referrals of patients with CKD from non-nephrology specialists (eg, general internal medicine) will be excluded. ETHICS AND DISSEMINATION: Ethics approval will not be required, as we will analyse data from studies that have already been published and are publicly accessible. We will share our findings using traditional approaches, including scientific presentations, open access peer-reviewed platforms, and appropriate government and public health agencies. PROSPERO REGISTRATION NUMBER: CRD42021247756.

The Delivery of Patient Care in Ontario's Family Health Teams during the First Wave of the COVID-19 Pandemic.

OBJECTIVE: The objective of this paper was to identify continuations and changes in care delivery methods in primary care teams during the COVID-19 pandemic. DESIGN: The study used a cross-sectional, web-based survey comprising close-ended and open-ended questions. SETTING: The setting comprised family health teams (FHTs) across Ontario, Canada. PARTICIPANTS: The participants included executive directors of FHTs or designates of their choosing. SURVEY: Descriptive statistics were derived from responses to close-ended questions, and responses to open-ended questions were coded using thematic analysis. RESULTS: With 93 participants, the response rate was 48%. Participants reported the continuation of in-person care, the implementation of virtual care across FHTs and collaboration within these teams and their communities.

A Web-Based Self-Management Support Prototype for Adults With Chronic Kidney Disease (My Kidneys My Health): Co-Design and Usability Testing.

BACKGROUND: Supporting patients to self-manage their chronic kidney disease (CKD) has been identified as a research priority by patients with CKD and those who care for them. Self-management has been shown to slow CKD progression and improve the quality of life of individuals living with the disease. Previous work has identified a need for a person-centered, theory-informed, web-based tool for CKD self-management that can be individualized to a patient's unique situation, priorities, and preferences. We addressed this gap using an integrated knowledge translation method and patient engagement principles. OBJECTIVE: The aim of this study is to conduct systematic co-design and usability testing of a web-based self-management prototype for adults with CKD (nondialysis and nontransplant) and their caregivers to enhance self-management support. METHODS: A multistep, iterative system development cycle was used to co-design and test the My Kidneys My Health prototype. The 3-step process included creating website features and content using 2 sequential focus groups with patients with CKD and caregivers, heuristic testing using the 10 heuristic principles by Nielsen, and usability testing through in-person 60-minute interviews with patients with CKD and their caregivers. Patients with CKD, caregivers, clinicians, researchers, software developers, graphic designers, and policy makers were involved in all steps of this study. RESULTS: In step 1, 18 participants (14 patients and 4 caregivers) attended one of the 2 sequential focus groups. The participants provided specific suggestions for simplifying navigation as well as suggestions to incorporate video, text, audio, interactive components, and visuals to convey information. A total of 5 reviewers completed the heuristic analysis (step 2), identifying items mainly related to navigation and functionality. Furthermore, 5 participants completed usability testing (step 3) and provided feedback on video production, navigation, features and functionality, and branding. Participants reported visiting the website repeatedly for the following features: personalized food tool, my health care provider question list, symptom guidance based on CKD severity, and medication advice. Usability was high, with a mean system usability score of 90 out of 100. CONCLUSIONS: The My Kidneys My Health prototype is a systematically developed, multifaceted, web-based CKD self-management support tool guided by the theory and preferences of patients with CKD and their caregivers. The website is user friendly and provides features that improve user experience by tailoring the content and resources to their needs. A feasibility study will provide insights into the acceptability of and engagement with the prototype and identify preliminary patient-reported outcomes (eg, self-efficacy) as well as potential factors related to implementation. This work is relevant given the shift to virtual care during the current pandemic times and provides patients with support when in-person care is restricted.

Prevalence of polypharmacy and associated adverse health outcomes in adult patients with chronic kidney disease: protocol for a systematic review and meta-analysis.

BACKGROUND: Polypharmacy, often defined as the concomitant use of ≥ 5 medications, has been identified as a significant global public health threat. Aging and multimorbidity are key drivers of polypharmacy and have been linked to a broad range of adverse health outcomes and mortality. Patients with chronic kidney disease (CKD) are particularly at high risk of polypharmacy and use of potentially inappropriate medications given the numerous risk factors and complications associated with CKD. The aim of this systematic review will be to assess the prevalence of polypharmacy among adult patients with CKD, and the potential association between polypharmacy and adverse health outcomes within this population. METHODS/DESIGN: We will search empirical databases such as MEDLINE, Embase, Cochrane Library, CINAHL, Web of Science, and PsycINFO and grey literature from inception onwards (with no language restrictions) for observational studies (e.g., cross-sectional or cohort studies) reporting the prevalence of polypharmacy in adult patients with CKD (all stages including dialysis). Two reviewers will independently screen all citations, full-text articles, and extract data. Potential conflicts will be resolved through discussion. The study methodological quality will be appraised using an appropriate tool. The primary outcome will be the prevalence of polypharmacy. Secondary outcomes will include any adverse health outcomes (e.g., worsening kidney function) in association with polypharmacy. If appropriate, we will conduct random effects meta-analysis of observational data to summarize the pooled prevalence of polypharmacy and the associations between polypharmacy and adverse outcomes. Statistical heterogeneity will be estimated using Cochran's Q and I2 index. Additional analyses will be conducted to explore the potential sources of heterogeneity (e.g., sex, kidney replacement therapy, multimorbidity). DISCUSSION: Given that polypharmacy is a major and a growing public health issue, our findings will highlight the prevalence of polypharmacy, hazards associated with it, and medication thresholds associated with adverse outcomes in patients with CKD. Our study will also draw attention to the prognostic importance of improving medication practices as a key priority area to help minimize the use of inappropriate medications in patients with CKD.

Prescriber-led practice changes that can bolster antimicrobial stewardship in community health care settings.

Stabilizing the emerging resistance of antibiotics depends on our ability to practise appropriate antimicrobial stewardship (AMS). Over 90% of antibiotics dispensed for human use are prescribed in community health care settings rather than in hospitals, with the main prescribers being family physicians, dentists, pharmacists and nurse practitioners working across a broad range of private offices, family health teams, urgent care clinics, emergency departments and long-term care homes. To improve the reach of AMS in community health care settings, the Public Health Agency of Canada partnered with Choosing Wisely Canada in 2017 to develop a focused campaign titled Using Antibiotics Wisely. This campaign is led by the prescribers of antibiotics themselves, who work in community health care settings and are better equipped to identify the specific changes that would support more appropriate use of antibiotics. This article describes these practice changes, the strengths and challenges of Using Antibiotics Wisely and future opportunities to further advance AMS across community health care settings.

Impact of the KidneyWise toolkit on chronic kidney disease referral practices in Ontario primary care: a prospective evaluation.

OBJECTIVES: Chronic kidney disease (CKD) is common; therefore, coordination of care between primary care and nephrology is important. Ontario Renal Network's KidneyWise toolkit was developed to provide guidance on the detection and management of people with CKD in primary care (www.kidneywise.ca). The aim of this study was to evaluate the impact of the April 2015 KidneyWise toolkit release on the characteristics of primary care referrals to nephrology. DESIGN AND SETTING: The study was a prospective pre-post design conducted at two nephrology sites (community site: Trillium Health Partners in Mississauga, Ontario, Canada, and academic site: St Joseph's Healthcare in Hamilton, Ontario, Canada). Referrals were compared during the 3-month time period immediately prior to, and during a 3-month period 1 year after, the toolkit release. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the change in proportion of referrals for CKD that met the KidneyWise criteria. Additional secondary referral and quality of care outcomes were also evaluated. Multivariable logistic regression was used to evaluate preselected variables for their independent association with referrals that met the KidneyWise criteria. RESULTS: The proportion of referrals for CKD among people who met the KidneyWise referral criteria did not significantly change from pre-KidneyWise to post-KidneyWise implementation (44.7% vs 45.8%, respectively, adjusted OR 1.16, 95% CI 0.85 to 1.59, p=0.36). The proportion of referrals for CKD that provided a urine albumin-creatinine ratio significantly increased post-KidneyWise (25.8% vs 43.8%, adjusted OR 1.45, 95% CI 1.06 to 1.97, p=0.02). The significant independent predictors of meeting the KidneyWise referral criteria were academic site, increased age and use of the KidneyWise referral form. CONCLUSIONS: We did not observe any change in the proportion of appropriate referrals for CKD at two large nephrology centres 1 year after implementation of the KidneyWise toolkit.

Canadian Society of Nephrology Commentary on the Kidney Disease Improving Global Outcomes 2017 Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder.

PURPOSE OF REVIEW: (1) To provide commentary on the 2017 update to the Kidney Disease Improving Global Outcomes (KDIGO) 2017 Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD); (2) to apply the evidence-based guideline update for implementation within the Canadian health care system; (3) to provide comment on the care of children with chronic kidney disease (CKD); and (4) to identify research priorities for Canadian patients. SOURCES OF INFORMATION: The KDIGO 2017 Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of CKD-MBD. METHODS: The commentary committee co-chairs selected potential members based on their knowledge of the Canadian kidney community, aiming for wide representation from relevant disciplines, academic and community centers, and different geographical regions. KEY FINDINGS: We agreed with many of the recommendations in the clinical practice guideline on the diagnosis, evaluation, prevention, and treatment of CKD-MBD. However, based on the uncommon occurrence of abnormalities in calcium and phosphate and the low likelihood of severe abnormalities in parathyroid hormone (PTH), we recommend against screening and monitoring levels of calcium, phosphate, PTH, and alkaline phosphatase in adults with CKD G3. We suggest and recommend monitoring these parameters in adults with CKD G4 and G5, respectively. In children, we agree that monitoring for CKD-MBD should begin in CKD G2, but we suggest measuring ionized calcium, rather than total calcium or calcium adjusted for albumin. With regard to vitamin D, we suggest against routine screening for vitamin D deficiency in adults with CKD G3-G5 and G1T-G5T and suggest following population health recommendations for adequate vitamin D intake. We recommend that the measurement and management of bone mineral density (BMD) be according to general population guidelines in CKD G3 and G3T, but we suggest against routine BMD testing in CKD G4-G5, CKD G4T-5T, and in children with CKD. Based on insufficient data, we also recommend against routine bone biopsy in clinical practice for adults with CKD or CKD-T, or in children with CKD, although we consider it an important research tool. LIMITATIONS: The committee relied on the evidence summaries produced by KDIGO. The CSN committee did not replicate or update the systematic reviews.

JUSTIFICATION: (1) Commenter les recommandations du KDIGO 2017 (Kidney Disease Improving Global Outcomes) sur les bonnes pratiques cliniques pour le diagnostic, l'évaluation et le traitement des troubles du métabolisme minéral osseux associés aux maladies rénales chroniques (TMO-MRC); (2) appliquer les lignes directrices actualisées et fondées sur les données probantes en vue de leur mise en œuvre dans le système de soins de santé canadien; (3) commenter les soins prodigués aux enfants atteints d'insuffisance rénale chronique (IRC) et (4) définir les priorités de recherche des patients Canadiens. SOURCES: Les recommandations du KDIGO 2017 (Kidney Disease Improving Global Outcomes) sur les bonnes pratiques cliniques pour le diagnostic, l'évaluation et le traitement des troubles du métabolisme minéral osseux associés aux maladies rénales chroniques (TMO-MRC). MÉTHODOLOGIE: Les coprésidents du comité ont sélectionné les membres potentiels sur la base de leur connaissance du secteur de la santé rénale au Canada, tout en visant une bonne représentation de toutes les disciplines concernées, des centres universitaires et communautaires et des différentes régions géographiques. PRINCIPAUX COMMENTAIRES: Nous approuvons un grand nombre des recommandations du KDIGO. Cependant, compte tenu de la rareté des anomalies du calcium et du phosphate et de la faible probabilité d'anomalies graves de la PTH (hormone parathyroïde), nous déconseillons le dépistage et la surveillance des taux de calcium, de phosphate, de PTH et de phosphatase alcaline chez les adultes atteints d'IRC de stade G3. Nous suggérons de mesurer ces paramètres chez les adultes de stade G4 et nous le recommandons pour les patients de stade G5. Chez les enfants, nous appuyons la recommandation de commencer la surveillance des TMO-MRC dès le stade G2, mais nous suggérons de mesurer le calcium ionisé plutôt que les taux de calcium total ou de calcium corrigé en fonction de l'albumine. En ce qui concerne la vitamine D, nous déconseillons le dépistage de routine des carences chez les adultes atteints d'IRC de stade G3 à G5 et G1T à G5T; nous suggérons plutôt de suivre les recommandations visant la population générale pour un apport adéquat en vitamine D. Nous recommandons que la mesure et la prise en charge de la densité minérale osseuse (DMO) se fassent en suivant les recommandations pour la population générale chez les adultes atteints d'IRC de stade G3 et G3T, mais nous déconseillons les tests de DMO de routine chez les adultes de stades G4-G5 et G4T-G5T, de même que chez les enfants atteints d'IRC. En raison de données insuffisantes, nous déconseillons également la pratique systématique d'une biopsie osseuse chez les adultes atteints d'IRC ou d'IRC-TMO, ainsi que chez les enfants atteints d'IRC, bien que nous la considérions comme un important outil de recherche. LIMITES: Le comité s'est appuyé sur le résumé des preuves rédigé par le KDIGO. Le comité de la SCN n'a pas reproduit ou mis à jour les revues systématiques.

Approach to management of suspected rabies exposures: what primary care physicians need to know.

OBJECTIVE: To review the role of primary care physicians, in conjunction with local public health units, in the management of suspected rabies exposures and to outline the current guidelines for the administration of rabies postexposure prophylaxis. SOURCES OF INFORMATION: Published guidelines on the topic of rabies were reviewed and additional articles were identified from key references. Various public health websites were also explored. Most evidence was level II or III. MAIN MESSAGE: Primary care physicians must always consider the risk of rabies when treating patients who have had animal-to-human exposures (eg, bite, scratch), and if indicated, postexposure prophylaxis must be administered as soon as possible because the infection is fatal once clinical symptoms develop. CONCLUSION: Human cases of rabies are almost entirely preventable if suspected exposures are identified and managed promptly and properly. Primary care physicians must continue to work together with local public health officials in order to minimize the threat of this deadly virus.

Quality of Chronic Kidney Disease Management in Canadian Primary Care.

Importance: Although patients with chronic kidney disease (CKD) are routinely managed in primary care settings, no nationally representative study has assessed the quality of care received by these patients in Canada. Objective: To evaluate the current state of CKD management in Canadian primary care practices to identify care gaps to guide development and implementation of national quality improvement initiatives. Design, Setting, and Participants: This cross-sectional study leveraged Canadian Primary Care Sentinel Surveillance Network data from January 1, 2010, to December 31, 2015, to develop a cohort of 46 162 patients with CKD managed in primary care practices. Data analysis was performed from August 8, 2018, to July 31, 2019. Main Outcomes and Measures: The study examined the proportion of patients with CKD who met a set of 12 quality indicators in 6 domains: (1) detection and recognition of CKD, (2) testing and monitoring of kidney function, (3) use of recommended medications, (4) monitoring after initiation of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs), (5) management of blood pressure, and (6) monitoring for glycemic control in those with diabetes and CKD. The study also analyzed associations of divergence from these quality indicators. Results: The cohort comprised 46 162 patients (mean [SD] age, 69.2 [14.0] years; 25 855 [56.0%] female) with stage 3 to 5 CKD. Only 4 of 12 quality indicators were met by 75% or more of the study cohort. These indicators were receipt of an outpatient serum creatinine test within 18 months after confirmation of CKD, receipt of blood pressure measurement at any time during follow-up, achieving a target blood pressure of 140/90 mm Hg or lower, and receiving a hemoglobin A1c test for monitoring diabetes during follow-up. Indicators in the domains of detection and recognition of CKD, testing and monitoring of kidney function (specifically, urine albumin to creatinine ratio testing), use of recommended medications, and appropriate monitoring after initiation of treatment with ACEIs or ARBs were not met. Only 6529 patients (18.4%) with CKD received a urine albumin test within 6 months of CKD diagnosis, and 3954 (39.4%) had a second measurement within 6 months of an abnormal baseline urine albumin level. Older age (≥85 years) and CKD stage 5 were significantly associated with not satisfying the criteria for the quality indicators across all domains. Across age categories, younger patients (aged 18-49 years) and older patients (≥75 years) were less likely to be tested for albuminuria (314 of 1689 patients aged 18-49 years [18.5%], 1983 of 11 919 patients aged 75-84 years [61.6%], and 614 of 5237 patients aged ≥85 years [11.7%] received the urine albumin to creatinine ratio test within 6 months of initial estimated glomerular filtration rate <60 mL/min per 1.73 m2; P < .001). Patients aged 18 to 49 years were less commonly prescribed recommended medications (222 of 2881 [7.7%]), whereas patients aged 75 to 84 years were prescribed ACEIs or ARBs most frequently (2328 of 5262 [44.2%]; P < .001). Conclusions and Relevance: The findings suggest that management of CKD across primary care practices in Canada varies according to quality indicator. This study revealed potential priority areas for quality improvement initiatives in Canadian primary care practices.

Prevalence and Demographics of CKD in Canadian Primary Care Practices: A Cross-sectional Study.

INTRODUCTION: Surveillance systems enable optimal care delivery and appropriate resource allocation, yet Canada lacks a dedicated surveillance system for chronic kidney disease (CKD). Using data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN), a national chronic disease surveillance system, this study describes the geographic, sociodemographic, and clinical variations in CKD prevalence in the Canadian primary care context. METHODS: This cross-sectional study included 559,745 adults in primary care in 5 provinces across Canada from 2010 through 2015. Data were analyzed by geographic (urban or rural residence), sociodemographic (age, sex, deprivation index), and clinical (medications prescribed, comorbid conditions) factors, using data from CPCSSN and the Canadian Deprivation Index. CKD stage 3 or higher was defined as 2 estimated glomerular filtration rate (eGFR) values of <60 ml/min per 1.73 m2 more than 90 days apart as of January 1, 2015. RESULTS: Prevalence of CKD was 71.9 per 1000 individuals and varied by geography, with the highest prevalence in rural settings compared with urban settings (86.2 vs. 68.4 per 1000). CKD was highly prevalent among individuals with 3 or more other chronic diseases (281.7 per 1000). Period prevalence of CKD indicated a slight decline over the study duration, from 53.4 per 1000 in 2010 to 46.5 per 1000 in 2014. CONCLUSION: This is the first study to estimate the prevalence of CKD in primary care in Canada at a national level. Results may facilitate further research, prioritization of care, and quality improvement activities to identify gaps and improvement in CKD care.

Preferences for a self-management e-health tool for patients with chronic kidney disease: results of a patient-oriented consensus workshop.

BACKGROUND: Electronic health (e-health) tools may support patients' self-management of chronic kidney disease. We aimed to identify preferences of patients with chronic kidney disease, caregivers and health care providers regarding content and features for an e-health tool to support chronic kidney disease self-management. METHODS: A patient-oriented research approach was taken, with 6 patient partners (5 patients and 1 caregiver) involved in study design, data collection and review of results. Patients, caregivers and clinicians from across Canada participated in a 1-day consensus workshop in June 2018. Using personas (fictional characters) and a cumulative voting technique, they identified preferences for content for 8 predetermined topics (understanding chronic kidney disease, diet, finances, medication, symptoms, travel, mental and physical health, work/school) and features for an e-health tool. RESULTS: There were 24 participants, including 11 patients and 6 caregivers, from across Canada. The following content suggestions were ranked the highest: basic information about kidneys, chronic kidney disease and disease progression; reliable information on diet requirements for chronic kidney disease and comorbidities, renal-friendly foods; affordability of medication, equipment, food, financial resources and planning; common medications, adverse effects, indications, cost and coverage; symptom types and management; travel limitations, insurance, access to health care, travel checklists; screening and supports to address mental health, cultural sensitivity, adjusting to new normal; and support to help integrate at work/school, restrictions. Preferred features included visuals, the ability to enter and track health information and interact with health care providers, "on-the-go" access, links to resources and access to personal health information. INTERPRETATION: A consensus workshop developed around personas was successful for identifying detailed subject matter for 8 predetermined topic areas, as well as preferred features to consider in the codevelopment of a chronic kidney disease self-management e-health tool. The use of personas could be applied to other applications in patient-oriented research exploring patient preferences and needs in order to improve care and relevant outcomes.
