Abstract

fetched live from OpenAlex

Background: Chronic kidney disease (CKD) is a risk factor for cardiovascular disease. The Kidney Disease Improving Global Outcomes 2013 guidelines and the Canadian Cardiovascular Society 2016 guidelines recommend statins for primary prevention of cardiovascular disease in CKD patients aged 50 years or older who are not receiving treatment with kidney transplant or dialysis. Objectives: To evaluate statin use for patients in the Vancouver General Hospital Kidney Care Clinic (VGH KCC) and to gain insight into the KCC nephrologists’ practices and perspectives regarding the prescribing of statins for patients with CKD. Methods: The study comprised 2 parts. Part 1 consisted of a cross-sectional study of all statin-eligible patients in the VGH KCC followed by a retrospective chart review. In the chart review, data were collected for 250 statin users and 250 non-users. Logistic regression analyses were performed to determine associations between demographic variables and statin use or non-use. Part 2 was an electronic survey of VGH KCC nephrologists. Results: Of the 813 statin-eligible patients, 512 (63%) were taking a statin. Patients were approximately 5 times more likely to be receiving statin therapy when it was indicated for secondary versus primary prevention (adjusted odds ratio 4.64, 95% confidence interval 2.95–7.47). Eight of the 9 KCC nephrologists completed the survey, and 7 (87.5%) of these respondents indicated that they never or rarely prescribed statins themselves to KCC patients for primary prevention. However, the same number reported that they sometimes or often suggested statin initiation to family physicians. Three of the respondents indicated agreement with guideline recommendations, but many stated that the decision for statin initiation should be individualized to the patient. Strategies to improve statin prescribing rates that were endorsed by respondents included educating family physicians, creating preprinted orders and laboratory requisitions for statin initiation, providing educational materials about statins to patients, and implementing a protocol for KCC pharmacists to counsel patients about statins. Conclusions: Many statin-eligible VGH KCC patients were not receiving statin therapy, and most of the KCC nephrologists considered statin prescribing as a role for family physicians. Within the KCC, future directions will be to develop a standardized approach to identify patients who would benefit from statin therapy, and to implement strategies to improve statin prescribing rates in appropriate patients. RÉSUMÉ Contexte : L’insuffisance rénale chronique (IRC) est un facteur de risque de maladie cardiovasculaire. Les directives du Kidney Disease Improving Global Outcomes de 2013 et celles de la Société canadienne de cardiologie de 2016 recommandent l’utilisation de statines comme mode de prévention principal des maladies cardiovasculaires par les patients âgés d’au moins 50 ans et souffrant d’IRC, qui ne reçoivent pas de traitement par greffe rénale ou dialyse. Objectifs : Évaluer l’utilisation des statines pour les patients résidant au Vancouver General Hospital Kidney Care Clinic (VGH KCC) et améliorer la compréhension des pratiques et points de vue des néphrologues de la KCC concernant la prescription de statines aux patients souffrant d’une IRC. Méthodes : L’étude comportait deux parties. La première consistait en une étude transversale de tous les patients admis à recevoir des statines au VGH KCC, suivie d’un examen rétrospectif des dossiers. Les données destinées à cet examen ont été recueillies auprès de 250 utilisateurs de statines et de 250 non-utilisateurs. Les analyses de régression logistique ont permis de déterminer les associations entre les variables démographiques et l’utilisation (ou non) de statines. La deuxième partie consistait en une enquête menée électroniquement auprès des néphrologues du VGH KCC. Résultats : Des 813 patients admissibles à l’utilisation de statines, 512 (63 %) en prenaient déjà. Les patients avaient environ cinq fois plus de chances de recevoir un traitement par statines, lorsque celles-ci étaient indiquées pour la prévention secondaire ou primaire (rapport de cote révisé 4,64, 95 % intervalle de confiance 2,95 - 7,47). Huit des neuf néphrologues de la KCC ont participé à l’enquête et sept (87,5 %) d’entre eux ont indiqué qu’ils n’avaient jamais, ou rarement, prescrit de statines aux patients du KCC dans le cadre d’une intervention primaire. Cependant, le même nombre de répondants a indiqué avoir parfois ou souvent proposé aux médecins de famille de commencer un traitement aux statines. Trois répondants ont indiqué être d’accord avec les recommandations préconisées dans les directives, mais bon nombre des néphrologues interrogés ont signalé que la décision d’entreprendre un tel traitement devait être individualisée. Les stratégies visant à améliorer les taux de prescription de statines approuvées par les répondants comprenaient la sensibilisation des médecins de famille, la création d’ordonnances et de demandes d’analyse en laboratoire préimprimées pour entreprendre un traitement aux statines, l’offre aux patients de matériel de formation sur le sujet et la mise en place d’un protocole pour les pharmaciens de la KCC leur permettant de conseiller les patients. Conclusions : Beaucoup de patients admissibles à un traitement aux statines du VGH KCC ne le recevaient pas, et la plupart des néphrologues de la KCC considéraient que la prescription de ce type de traitement relevait des médecins de famille. Au sein de la KCC, les orientations futures consisteront à élaborer une approche standardisée pour identifier les patients qui tireraient profit d’une thérapie aux statines et à mettre en place des stratégies visant à améliorer les taux de prescription de statines aux patients concernés.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
