Development and Validation of Patient Education Tools for Deprescribing in Patients on Hemodialysis.

Background: Deprescribing is a patient-centered solution to reducing polypharmacy in patients on hemodialysis (HD). In a deprescribing pilot study, patients were hesitant to participate due to limited understanding of their own medications and their unfamiliarity with the concept of deprescribing. Therefore, patient education materials designed to address these knowledge gaps can overcome barriers to shared decision-making and reduce hesitancy regarding deprescribing. Objective: To develop and validate a medication-specific, patient education toolkit (bulletin and video) that will supplement an upcoming nationwide deprescribing program for patients on HD. Methods: Patient education tools were developed based on the content of previously validated deprescribing algorithms and literature searches for patients' preferences in education. A preliminary round of validation was completed by 5 clinicians to provide feedback on the accuracy and clarity of the education tools. Then, 3 validation rounds were completed by patients on HD across 3 sites in Vancouver, Winnipeg, and Toronto. Content and face validity were evaluated on a 4-point and 5-point Likert scale, respectively. The content validity index (CVI) score was calculated after each round, and revisions were made based on patient feedback. Results: A total of 105 patients participated in the validation. All 10 education tools achieved content and face validity after 3 rounds. The CVI score was 1.0 for most of the tools, with 0.95 being the lowest value. Face validity ranged from 72% to 100%, with majority scoring above 90%. Conclusion: Ten patient education tools on deprescribing were developed and validated by patients on HD. These validated, medication-specific education tools are the first of its kind for patients on HD and will be used in a nationwide implementation study alongside the validated deprescribing algorithms developed by our research group.

Contexte: La déprescription est une solution axée sur le patient pour réduire la polypharmacie chez les patients sous hémodialyse (HD). Dans une étude pilote sur la déprescription, les patients ont hésité à participer en raison de leur compréhension limitée de leurs propres médicaments et de leur manque de connaissance du concept de déprescription. Par conséquent, du matériel éducatif conçu pour combler ces lacunes dans les connaissances des patients pourrait surmonter les obstacles à la prise de décision partagée et réduire les hésitations à l'égard de la déprescription. Objectifs: Développer et valider une trousse d'information (bulletin et vidéo) pour les patients portant sur les médicaments. Cette trousse viendra compléter un futur programme national de déprescription pour les patients sous HD. Méthodologie: Des outils d'éducation pour les patients ont été développés à partir du contenu d'algorithmes de déprescription validés précédemment et de recherches documentaires sur les préférences des patients en matière d'éducation. Une ronde préliminaire de validation a été complétée par cinq cliniciens afin d'obtenir des commentaires sur l'exactitude et la clarté des outils d'éducation. Trois cycles de validation ont ensuite été réalisés par des patients sous HD dans trois sites: Vancouver, Winnipeg et Toronto. La validité du contenu et la validité apparente ont été évaluées à l'aide d'échelles de Likert à 4 et 5 points, respectivement. L'indice de validité du contenu (IVC) a été calculé après chaque ronde et des révisions ont été effectuées en fonction des commentaires des patients. Résultats: En tout, 105 patients ont participé à la validation. La validité du contenu et la validité apparente ont été atteintes pour les dix outils d'éducation après trois rondes auprès des patients. L'IVC s'établissait à 1,0 pour la plupart des outils évalués; 0,95 était la valeur d'indice la plus faible. La validité apparente variait entre 72% et 100%, la majorité des outils ayant obtenu un score supérieur à 90%. Conclusion: Dix outils d'éducation pour les patients portant sur la déprescription ont été développés et validés par des patients sous HD. Ces outils d'éducation validés portant spécifiquement sur les médicaments sont les premiers du genre conçus pour les patients sous HD. Ils seront utilisés dans le cadre d'une étude nationale de mise en œuvre, parallèlement aux algorithmes validés de déprescription qui ont été développés par notre groupe de recherche.

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.

A Research Protocol for Implementation and Evaluation of a Patient-Focused eHealth Intervention for Chronic Kidney Disease.

Self-management in chronic kidney disease (CKD) can slow disease progression; however, there are few tools available to support patients with early CKD. My Kidneys My Health is a patient-focused electronic health (eHealth) self-management tool developed by patients and caregivers. This study will investigate the implementation of My Kidneys My Health across primary care and general nephrology clinics. The study aims to: (1) identify and address barriers and facilitators that may impact implementation and sustainability of the website into routine clinical care; (2) evaluate implementation quality to inform spread and scale-up. We will conduct a multi-stage approach using qualitative methods, guided by the Quality Implementation Framework and using a qualitative content analysis approach. First, we will identify perceived barriers and facilitators to implementation and considerations for sustainability through interviews with clinicians, based on the Readiness Thinking Tool and the Long Term Success Tool. Analysis will be guided by the Consolidated Framework for Implementation Research and the Theoretical Domains Framework. Appropriate implementation strategies will be identified using the Expert Recommendations for Implementing Change compilation, and implementation plans will be developed based on Proctor's recommendations and the Action, Actor, Context, Target, Time framework. Finally, we will explore implementation quality guided by the RE-AIM framework. There is limited literature describing systematic approaches to implementing and sustaining patient-focused self-management tools into clinical care, in addition to employing tailored implementation strategies to promote adoption and sustainability. We aim to generate insights on how My Kidneys My Health can be integrated into clinical care and how to sustain use of patient-centric eHealth tools in clinical settings on a larger scale.

Development and Preliminary Psychometric Testing of an Adult Chronic Kidney Disease Self-Management (CKD-SM) Questionnaire.

BACKGROUND: Self-management focused interventions to slow chronic kidney disease (CKD) progression are increasingly common. However, valid self-report instruments to evaluate the effectiveness of self-management interventions in CKD are limited. OBJECTIVE: We sought to develop and conduct preliminary psychometric testing of a patient-informed questionnaire to assess aspects of CKD self-management for patients with CKD categories G2-G5 (not on kidney replacement therapy [KRT]). DESIGN: Self-administered electronic questionnaires (multiphase). SETTING: Online. SAMPLE: Canadian adults with CKD categories G2-G5 (not on KRT). METHODS: The CKD-SM questionnaire was developed and tested in 4 phases. First, we used a content coverage matrix to identify potential questionnaire items based on existing self-efficacy questionnaires, self-management theories, and patient-identified priorities. Second, the draft questionnaire was reviewed by a multidisciplinary expert panel using percent acceptance to finalize the questionnaire. Third, we tested an electronic version of the questionnaire with patients with CKD, evaluating preliminary psychometric properties including internal consistency, face validity, and content validity. Finally, we tested the questionnaire within a CKD self-management intervention study and collected data on internal consistency, test-retest reliability, and pre-post responsiveness. RESULTS: We identified 22 potential questionnaire items for the first round of expert panel review. Thirteen items were retained in the first round. Eleven additional items were tested in the second review round and all were retained. Of the 24 items retained following expert review of the questionnaire, 21 had greater than 85% acceptance (content validity index [CVI], 0.75-1.00) and 3 items had 75% acceptance (CVI, 0.5). Thirty patients with CKD from across Canada participated in the pilot testing, and 29 patients participated in the CKD self-management intervention study. In the pilot test, several participants requested inclusion of a question that explicitly addressed mental health; consequently, an additional item relating to mental health was included prior to the intervention study (final questionnaire total was 25 items). Internal consistency (Cronbach α) was high for both the pilot (0.921) and intervention study (0.912). Preintervention test-retest reliability, measured with intraclass correlation coefficient, was acceptable (0.732, 95% confidence interval, 0.686-0.771, P < .001), and paired pre/postintervention comparison, measured with Wilcoxon sign-rank, demonstrated significant increases in self-management (P < .05) despite stable preintervention test-retest responses. Participants were satisfied with the content, wording, and design. LIMITATIONS: The sample sizes were small for each component of the analysis, and the sampling was consecutive/convenience-based. CONCLUSIONS: We used self-management theories, patient-identified self-management needs, expert review, and conducted preliminary psychometric testing to finalize a CKD self-management questionnaire for patients with G2-G5 CKD (not on KRT). The finalized questionnaire assesses aspects of self-management for individuals with CKD and may be particularly helpful as a tool to evaluate self-management interventions among patients with CKD.

CONTEXTE: Les interventions focalisées sur la prise en charge par le patient qui visent à ralentir la progression de l'insuffisance rénale chronique (IRC) sont de plus en plus courantes. Il existe cependant peu d'outils d'autodéclaration validés pour évaluer l'efficacité de ces interventions en contexte d'IRC. OBJECTIFS: Nous souhaitions élaborer un questionnaire destiné aux patients pour évaluer les aspects de la prise en charge de la néphropathie chronique par les patients atteints d'IRC de stade G2-G5 (ne suivant aucune thérapie de remplacement rénal [TRR]), puis réaliser des tests psychométriques préliminaires. CONCEPTION: Questionnaires électroniques autoadministrés (multiphases). CADRE: En ligne. ÉCHANTILLON: Des Canadiens adultes atteints d'IRC de grade G2-G5 (ne suivant aucune TRR). MÉTHODOLOGIE: Le questionnaire CKD-SM a été développé et testé en quatre phases : 1) une matrice de couverture de contenu a été utilisée pour déterminer les possibles éléments du questionnaire à partir des questionnaires d'auto-efficacité existants, des théories de prise en charge par le patient et des priorités identifiées par le patient; 2) le questionnaire préliminaire a été examiné par un groupe d'experts multidisciplinaire et finalisé avec le pourcentage d'acceptation; 3) une version électronique du questionnaire a été testée auprès de patients atteints d'IRC, pour en évaluer les propriétés psychométriques préliminaires, notamment la cohérence interne et la validité de la forme et du contenu, et enfin; 4) le questionnaire a été testé dans le cadre d'une étude portant sur les interventions par le patient en IRC et recueillant des données sur la cohérence interne, la fiabilité test-retest et la réactivité avant et après le test. RÉSULTATS: Nous avons défini 22 questions potentielles lors du premier tour de révision par le groupe d'experts. Treize questions ont été retenues au premier tour; onze questions supplémentaires ont été testées lors de la deuxième révision, et toutes ont été adoptées. Parmi les 24 questions retenues après révision du questionnaire par les experts, 21 présentaient une acceptation supérieure à 85 % (ratio de validité du contenu [RVC] : 0,75-1,00), contre 75 % pour les trois autres (RVC 0,5). Trente patients atteints d'IRC de partout au Canada ont participé à l'essai pilote tandis que 29 ont participé à l'étude d'intervention initiées par le patient en IRC. Pendant l'essai pilote, plusieurs participants ont demandé l'inclusion d'une question traitant explicitement de santé mentale; une question supplémentaire relative à la santé mentale a donc été incluse avant l'étude d'intervention (le questionnaire final comportait 25 questions). La cohérence interne (alpha de Cronbach) était élevée tant pour le pilote (0,921) que pour l'étude d'intervention (0,912). La fiabilité du test-retest préintervention, mesurée avec le coefficient de corrélation intra-classe, s'est avérée acceptable (0,732; IC : 0,686-0,771; p=<0,001) et la comparaison préintervention/post-intervention en paire, mesurée avec le test de rang de Wilcoxon, a montré une augmentation significative des interventions initiées par le patient (p<0,05) malgré des réponses stables au test-retest préintervention. Les participants se sont dits satisfaits du contenu, du libellé et de la conception de l'étude. LIMITES: Les échantillons pour chaque composante de l'analyse étaient faibles et l'échantillonnage était consécutif/basé sur la commodité. CONCLUSION: Nous avons utilisé des théories de prise en charge par le patient, les besoins identifiés par les patients, une revue par des experts et effectué des tests psychométriques préliminaires pour finaliser un questionnaire de prise en charge initiée par le patient de l'IRC (CKD-SM) pour les patients atteints d'IRC de stade G2-G5 (sans TRR). Le questionnaire finalisé évalue les aspects de l'autogestion chez les personnes atteintes d'IRC et peut être particulièrement utile comme outil d'évaluation de ces interventions chez ces patients.

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.

Development and Validation of Nine Deprescribing Algorithms for Patients on Hemodialysis to Decrease Polypharmacy.

BACKGROUND: Polypharmacy is ubiquitous in patients on hemodialysis (HD), and increases risk of adverse events, medication interactions, nonadherence, and mortality. Appropriately applied deprescribing can potentially minimize polypharmacy risks. Existing guidelines are unsuitable for nephrology clinicians as they lack specific instructions on how to deprescribe and which safety parameters to monitor. OBJECTIVE: To develop and validate deprescribing algorithms for nine medication classes to decrease polypharmacy in patients on HD. DESIGN: Questionnaires and materials sent electronically. PARTICIPANTS: Nephrology practitioners across Canada (nephrologists, nurse practitioners, renal pharmacists). METHODS: A literature search was performed to develop the initial algorithms via Lynn's method for development of content-valid clinical tools. Content and face validity of the algorithms was evaluated over three interview rounds using Lynn's method for determining content validity. Canadian nephrology clinicians each evaluated three algorithms (15 clinicians per round, 45 clinicians in total) by rating each algorithm component on a four-point Likert scale for relevance; face validity was rated on a five-point scale. After each round, content validity index of each component was calculated and revisions made based on feedback. If content validity was not achieved after three rounds, additional rounds were completed until content validity was achieved. RESULTS: After three rounds of validation, six algorithms achieved content validity. After an additional round, the remaining three algorithms achieved content validity. The proportion of clinicians rating each face validity statement as "Agree" or "Strongly Agree" ranged from 84% to 95% (average of all five questions, across three rounds). LIMITATIONS: Algorithm development was guided by existing deprescribing protocols intended for the general population and the expert opinions of our study team, due to a lack of background literature on HD-specific deprescribing protocols. There is no universally accepted method for the validation of clinical decision-making tools. CONCLUSIONS: Nine medication-specific deprescribing algorithms for patients on HD were developed and validated by clinician review. Our algorithms are the first medication-specific, patient-centric deprescribing guidelines developed and validated for patients on HD.

CONTEXTE: La polypharmacie est très répandue chez les patients hémodialysés et augmente le risque d'événements indésirables, d'interactions médicamenteuses, d'inobservance au traitement et de mortalité. La déprescription, appliquée de façon appropriée, peut réduire les risques associés à la polypharmacie. Les directives de déprescription existantes ne conviennent cependant pas aux cliniciens en néphrologie puisqu'elles ne renferment aucune indication spécifique sur la manière de procéder ni sur les paramètres de sécurité à surveiller. OBJECTIF: Développer et valider des algorithmes de déprescription pour neuf classes de médicaments en vue de réduire la polypharmacie chez les patients hémodialysés. CONCEPTION: Des questionnaires et des documents envoyés par voie électronique. PARTICIPANTS: Des praticiens en néphrologies de partout au Canada (néphrologues, infirmières-praticiennes, pharmaciens spécialisés en néphrologie). MÉTHODOLOGIE: Une recherche bibliographique a été effectuée pour développer les algorithmes initiaux avec la méthode de Lynn pour le développement d'outils cliniques à contenu validé. Le contenu et la validité apparente des algorithmes ont été évalués au cours de trois cycles d'interviews par la méthode de Lynn pour déterminer la validité d'un contenu. Les praticiens interviewés (15 par cycle, pour un total de 45) ont chacun évalué trois algorithmes en classant la pertinence de leurs composants sur une échelle de Likert en quatre points, et en classant leur validité apparente sur une échelle en cinq points. Après chaque cycle, l'indice de validité du contenu a été calculé pour chaque composant et des correctifs ont été apportés en fonction de la rétroaction. Si la validité du contenu n'était pas atteinte après trois cycles, des cycles supplémentaires étaient effectués jusqu'à ce que celle-ci soit atteinte. RÉSULTATS: Six algorithmes ont atteint la validité après trois cycles de validation. Les trois algorithmes restants l'ont atteint après un cycle supplémentaire. La proportion de cliniciens ayant attribué la mention de validité apparente « d'accord ¼ ou « tout à fait d'accord ¼ se situait entre 84 et 95 % (moyenne des cinq questions, sur trois cycles). LIMITES: Le développement des algorithmes repose sur les protocoles de déprescription existants, destinés à la population générale, et sur l'avis des experts de notre équipe d'étude puisque la documentation portant sur des protocoles de déprescription spécifiques aux patients hémodialysés est insuffisante. Il n'existe aucune méthode universellement acceptée pour valider les outils de décision clinique. CONCLUSION: Neuf algorithmes de déprescription spécifiques aux patients hémodialysés ont été développés et validés par révision des cliniciens. Nos algorithmes sont les premiers guides de déprescription développés et validés spécifiquement pour les médicaments des patients hémodialysés. ENREGISTREMENT DE L'ESSAI: Sans objet ­ il s'agit d'une série de questionnaires.

A Higher Concentration of Dialysate Magnesium to Reduce the Frequency of Muscle Cramps: A Narrative Review.

PURPOSE OF REVIEW: Strategies to mitigate muscle cramps are a top research priority for patients receiving hemodialysis. As hypomagnesemia is a possible risk factor for cramping, we reviewed the literature to better understand the physiology of cramping as well as the epidemiology of hypomagnesemia and muscle cramps. We also sought to review the evidence from interventional studies on the effect of oral and dialysate magnesium-based therapies on muscle cramps. SOURCES OF INFORMATION: Peer-reviewed articles. METHODS: We searched for relevant articles in major bibliographic databases including MEDLINE and EMBASE. The methodological quality of interventional studies was assessed using a modified version of the Downs and Blacks criteria checklist. KEY FINDINGS: The etiology of muscle cramps in patients receiving hemodialysis is poorly understood and there are no clear evidence-based prevention or treatment strategies. Several factors may play a role including a low concentration of serum magnesium. The prevalence of hypomagnesemia (concentration of <0.7 mmol/L) in patients receiving hemodialysis ranges from 10% to 20%. Causes of hypomagnesemia include a low dietary intake of magnesium, use of medications that inhibit magnesium absorption (eg, proton pump inhibitors), increased magnesium excretion (eg, high-dose loop diuretics), and a low concentration of dialysate magnesium. Dialysate magnesium concentrations of ≤0.5 mmol/L may be associated with a decrease in serum magnesium concentration over time. Preliminary evidence from observational and interventional studies suggests a higher dialysate magnesium concentration will raise serum magnesium concentrations and may reduce the frequency and severity of muscle cramps. However, the quality of evidence supporting this benefit is limited, and larger, multicenter clinical trials are needed to further determine if magnesium-based therapy can reduce muscle cramps in patients receiving hemodialysis. In studies conducted to date, increasing the concentration of dialysate magnesium appears to be well-tolerated and is associated with a low risk of symptomatic hypermagnesemia. LIMITATIONS: Few interventional studies have examined the effect of magnesium-based therapy on muscle cramps in patients receiving hemodialysis and most were nonrandomized, pre-post study designs.

CONTEXTE MOTIVANT LA REVUE: Les stratégies visant à atténuer les crampes musculaires sont parmi les principales priorités de recherche des patients hémodialysés. L'hypomagnésémie étant un possible facteur de risque, nous avons procédé à une revue de la littérature afin de mieux en comprendre l'épidémiologie, et d'examiner la physiologie et l'épidémiologie des crampes musculaires. Nous souhaitions également examiner les données probantes issues d'études interventionnelles portant sur l'effet des thérapies à base de dialysat de magnésium et de magnésium oral sur les crampes musculaires. SOURCES: Articles examinés par les pairs. MÉTHODOLOGIE: Nous avons cherché les articles pertinents dans les principales bases de données bibliographiques, notamment MEDLINE et EMBASE. La qualité méthodologique a été évaluée à l'aide d'une version modifiée des critères de contrôle de la qualité des études de Downs et Black. PRINCIPAUX RÉSULTATS: L'étiologie des crampes musculaires chez les patients hémodialysés est mal comprise et il n'existe aucune stratégie de prévention ou traitement clairement fondé sur des données probantes. Plusieurs facteurs pourraient jouer un rôle, notamment de faibles concentrations sériques de magnésium. La prévalence de l'hypomagnésémie (concentration inférieure à 0,7 mmol/L) chez les patients hémodialysés variait de 10 à 20 %. Une faible consommation de magnésium dans l'alimentation, la prise de médicaments inhibant l'absorption du magnésium (ex. les inhibiteurs de la pompe à protons), l'excrétion accrue du magnésium (ex. dose élevée de diurétiques de l'anse) et une faible concentration de dialysat de magnésium figuraient parmi les causes d'hypomagnésémie. Un taux de dialysat de magnésium inférieur ou égal à 0,5 mmol/L pourrait être associé à une diminution de la concentration sérique de magnésium au fil du temps. Les résultats préliminaires de certaines études observationnelles et interventionnelles suggèrent qu'une concentration sérique plus élevée de magnésium dans le dialysat augmenterait les concentrations sériques de magnésium et pourrait réduire la fréquence et la sévérité des épisodes de crampes musculaires. La qualité des preuves appuyant ce bienfait est cependant limitée. Des essais multicentriques et à plus vaste échelle sont nécessaires pour juger si un traitement à base de magnésium peut véritablement réduire les crampes musculaires chez les patients hémodialysés. Dans les études menées jusqu'à maintenant, l'augmentation de la concentration de dialysat de magnésium semblait bien tolérée et a été associée à un faible risque d'hypermagnésémie symptomatique. LIMITES: Peu d'études interventionnelles ont examiné l'effet de la prise de magnésium sur les crampes musculaires des patients hémodialysés, et la plupart de celles-ci constituaient des plans pré- ou post-études non randomisées.

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.

Content and Quality of Websites for Patients With Chronic Kidney Disease: An Environmental Scan.

BACKGROUND: Although numerous websites for patients with chronic kidney disease (CKD) are available, little is known about their content and quality. OBJECTIVE: To evaluate the quality of CKD websites, and the degree to which they align with information needs identified by patients with CKD. METHODS: We identified websites by entering "chronic kidney disease" in 3 search engines: Google.com (with regional variants for Australia, Canada, the United Kingdom, and the United States), Bing.com, and Yahoo.com. We included the first 50 unique English-language sites from each search. We evaluated website content using a 30-point scale comprising 8 priority content domains identified by patients with CKD (understanding CKD, diet, symptoms, medications, mental/physical health, finances, travel, and work/school). We used standardized tools to evaluate usability, reliability, and readability (DISCERN, HONcode, LIDA, Reading Ease, and Reading Grade Level). Two reviewers independently conducted the search, screen, and evaluation. RESULTS: Of the 2093 websites identified, 115 were included. Overall, sites covered a mean (SD) of 29% (17.8) of the CKD content areas. The proportion of sites covering content related to understanding CKD, symptoms, and diet was highest (97%, 80%, and 72%, respectively). The proportion of sites covering travel, finances, and work/school content was lowest (22%, 12%, and 12%, respectively). The mean (SD) scores for DISCERN, LIDA and HONcode were 68% (14.6), 71% (14.4), and 75% (17.2), respectively, considered above average for usability and reliability. The mean (SD) Reading Grade Level was 10.6 (2.8) and Reading Ease was 49.8 (14.4), suggesting poor readability. CONCLUSIONS: Although many CKD web sites were of reasonable quality, their readability was poor. Furthermore, most sites covered less than 30% of the content patients identified as important for CKD self-management. These results will inform content gaps in internet-accessible information on CKD self-management that should be addressed by future eHealth web-based tools.

CONTEXTE: Bien qu'il existe de nombreux sites Web s'adressant aux patients atteints d'insuffisance rénale chronique (IRC), on en sait peu sur leur qualité et sur la pertinence de leur contenu. OBJECTIFS: Évaluer la qualité de sites Web traitant de l'IRC et vérifier s'ils sont en phase avec les besoins d'information formulés par les patients. MÉTHODOLOGIE: Nous avons répertorié des sites Web en entrant chronic kidney disease (insuffisance rénale chronique) dans trois moteurs de recherche, soit Google.com (et ses variantes régionales australienne, canadienne, britannique et étatsunienne), Bing.com et Yahoo.com. Ont été inclus les 50 premiers sites en anglais s'affichant sur chacun. Le contenu a été évalué avec une échelle en 30 points englobant huit domaines d'intérêt cités par les patients atteints d'IRC, soit Understanding CKD (comprendre l'IRC), Diet (régime alimentaire), Symptoms (symptômes), Medications (médicaments), Mental/Physical Health (santé physique/mentale), Finances (finances), Travel (voyage) et Work/School (travail/études). Des outils normalisés (DISCERN, HONcode, LIDA, Flesch Reading Ease, Flesch-Kincaid Reading Grade Level) ont été employés pour évaluer la convivialité, la fiabilité et la lisibilité des contenus. Deux examinateurs ont procédé à la recherche, au triage et à l'évaluation des sites de façon indépendante. RÉSULTATS: Des 2 093 sites répertoriés, 115 ont été inclus. Dans l'ensemble, ceux-ci couvraient les domaines d'intérêt à 29 % (17,8) en moyenne. La compréhension de l'IRC (97 %), les symptômes (80 %) et le régime alimentaire (72 %) se sont révélés les sujets abordés par une plus grande proportion des sites évalués. Les voyages (22 %), la situation financière (12 %) et le travail/les études (12 %) constituaient quant à eux les sujets les moins couverts. Les scores moyens pour DISCERN (68 % [14,6]), LIDA (71 % [14,4]) et HONcode (75 % [17,2]) se sont avérés au-dessus de la moyenne pour la convivialité et la fiabilité. Le score moyen au Reading Grade Level était de 10,6 (2,8) et celui du Reading Ease était de 49,8 (14,4), suggérant une faible lisibilité. CONCLUSION: Bien que la qualité de plusieurs sites Web traitant de l'IRC se soit révélée satisfaisante, leur lisibilité était faible. De plus, la plupart couvraient moins de 30 % du contenu jugé important par les patients dans l'autogestion de la maladie. Ces résultats mettront en lumière les lacunes de l'information accessible sur internet quant à l'autogestion de l'IRC; lacunes qui devraient être comblées par les futurs outils de santé en ligne.

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.

Self-management interventions for adults with chronic kidney disease: a scoping review.

OBJECTIVE: To systematically identify and describe self-management interventions for adult patients with chronic kidney disease (CKD). SETTING: Community-based. PARTICIPANTS: Adults with CKD stages 1-5 (not requiring kidney replacement therapy). INTERVENTIONS: Self-management strategies for adults with CKD. PRIMARY AND SECONDARY OUTCOME MEASURES: Using a scoping review, electronic databases and grey literature were searched in October 2016 to identify self-management interventions for adults with CKD stages 1-5 (not requiring kidney replacement therapy). Randomised controlled trials (RCTs), non-RCTs, qualitative and mixed method studies were included and study selection and data extraction were independently performed by two reviewers. Outcomes included behaviours, cognitions, physiological measures, symptoms, health status and healthcare. RESULTS: Fifty studies (19 RCTs, 7 quasi-experimental, 5 observational, 13 pre-post intervention, 1 mixed method and 5 qualitative) reporting 45 interventions were included. The most common intervention topic was diet/nutrition and interventions were regularly delivered face to face. Interventions were administered by a variety of providers, with nursing professionals the most common health professional group. Cognitions (ie, changes in general CKD knowledge, perceived self-management and motivation) were the most frequently reported outcome domain that showed improvement. Less than 1% of the interventions were co-developed with patients and 20% were based on a theory or framework. CONCLUSIONS: There was a wide range of self-management interventions with considerable variability in outcomes for adults with CKD. Major gaps in the literature include lack of patient engagement in the design of the interventions, with the majority of interventions not applying a behavioural change theory to inform their development. This work highlights the need to involve patients to co-developed and evaluate a self-management intervention based on sound theories and clinical evidence.
