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.

Abstract Background Both reduced glomerular filtration rate and increased urine albumin excretion, markers of chronic kidney disease (CKD), are associated with increased risk of atherosclerotic cardiovascular disease (ASCVD). However, CKD is not recognized as an ASCVD risk equivalent by most lipid guidelines. Statin medications, especially when combined with ezetimibe, significantly reduce ASCVD risk in patients with nondialysis-dependent CKD. Unless physicians recognize the heightened ASCVD risk in this population, statins may not be prescribed in the absence of clinical cardiovascular disease or diabetes, a recognized ASCVD risk equivalent. We examined statin use in adults with nondialysis-dependent CKD and examined whether the use differed in the presence of clinical ASCVD and diabetes. Methods This study ascertained statin use from pharmacy dispensing records during fiscal years 2012 and 2013 from the US Department of Veterans Affairs Healthcare System. The study included 581 344 veterans aged ≥50 years with nondialysis-dependent CKD Stages 3–5 with no history of kidney transplantation or dialysis. The 10-year predicted ASCVD risk was calculated with the pooled risk equation. Results Of veterans with CKD, 62.1% used statins in 2012 and 55.4% used statins continuously over 2 years (2012–13). Statin use in 2012 was 76.2 and 75.5% among veterans with CKD and ASCVD or diabetes, respectively, but in the absence of ASCVD, diabetes or a diagnosis of hyperlipidemia, statin use was 21.8% (P < 0.001). The 10-year predicted ASCVD risk was ≥7.5% in 95.1% of veterans with CKD, regardless of diabetes status. Conclusions Statin use is low in veterans with nondialysis-dependent CKD in the absence of ASCVD or diabetes despite high-predicted ASCVD risk. Future studies should examine other populations.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Cardiovascular disease (CVD) is a major cause of morbidity and mortality in individuals with chronic kidney disease (CKD). Aspirin is widely used in secondary prevention of cardiovascular disease. Its use in primary prevention, particularly in CKD, is less clear. Previous reviews have offered inconclusive findings for the benefit of aspirin in CKD. Recent trials have been completed that may help provide more conclusive answers in CKD. Purpose This study aimed to assess the role of aspirin in the primary prevention of CVD and its associated adverse events in individuals with CKD. Methods A pre-defined protocol registered with PROSPERO (CRD42014008860) was used. The OVID Medline and EMBASE databases were searched for studies from 1996 to the 15th September 2020. Abstracts and full-texts were screened independently by two reviewers. Randomised controlled trials that compared aspirin to placebo in individuals with non-endstage CKD without CVD nor primary renal disease were included. The primary outcomes of interests were: CVD, major and minor bleeding events. Secondary outcomes of interest were: all-cause mortality, coronary artery disease and stroke. A meta-analysis was conducted using a random-effects model to calculate a pooled relative risk (RR). Results Five trials were included with 434 CVD events in 7,825 individuals with CKD. Aspirin offered no statistically significant benefit in reduction of CVD events (RR = 0.79, 95%CI: 0.57, 1.09) but significantly increased both minor (RR = 2.62, 95%CI: 1.64, 4.20) and major bleeding (RR= 1.51, 95%CI: 1.13, 2.02) events compared to placebo. Aspirin conferred no benefit for all-cause mortality (RR= 0.89, 95%CI: 0.64, 1.22), coronary heart disease (RR= 0.66, 95%CI: 0.27, 1.63) and stroke (RR= 0.94, 95%CI: 0.55, 1.58). Conclusion Aspirin cannot be recommended for the primary prevention of CVD in individuals with CKD as it offers no conclusive benefit and increases the risk of bleeding. Other strategies to optimise CVD primary prevention in individuals with CKD should be prioritised.
