AIMS:Prior studies suggest that sodium-glucose cotransporter-2 inhibitors (SGLT2is) may decrease the incidence of atrial fibrillation (AF). However, it is unknown whether SGLT2i can attenuate the disease course of AF among patients with pre-existing AF and Type II diabetes mellitus (DM). In this study, our objective was to examine the association between SGLT2i prescription and arrhythmic outcomes among patients with DM and pre-existing AF. METHODS AND RESULTS:We conducted a population-based cohort study of adults with DM and AF between 2014 and 2019. Using a prevalent new-user design, individuals prescribed SGLT2i were matched 1:1 to those prescribed dipeptidyl peptidase-4 inhibitors (DPP4is) based on time-conditional propensity scores. The primary endpoint was a composite of AF-related healthcare utilization (i.e. hospitalization, emergency department visits, electrical cardioversion, or catheter ablation). Secondary outcome measures included all-cause mortality, heart failure (HF) hospitalization, and ischaemic stroke or transient ischaemic attack (TIA). Cox proportional hazard models were used to examine the association of SGLT2i with the study endpoint. Among 2242 patients with DM and AF followed for an average of 3.0 years, the primary endpoint occurred in 8.7% (n = 97) of patients in the SGLT2i group vs. 10.0% (n = 112) of patients in the DPP4i group [adjusted hazard ratio 0.73 (95% confidence interval 0.55-0.96; P = 0.03)]. Sodium-glucose cotransporter-2 inhibitors were associated with significant reductions in all-cause mortality and HF hospitalization, but there was no difference in the risk of ischaemic stroke/TIA. CONCLUSION:Among patients with DM and pre-existing AF, SGLT2is are associated with decreased AF-related health resource utilization and improved arrhythmic outcomes compared with DPP4is.

AIM:Canadian guidelines recommend metformin as first-line therapy for incident uncomplicated type 2 diabetes and the vast majority of patients are treated accordingly. However, only 54% 65% remain on treatment after 1 year, with the highest discontinuation rates within the first 3 months. The purpose of this study was: (a) to identify individual and clinical factors associated with metformin discontinuation among patients with newly diagnosed uncomplicated type 2 diabetes in Alberta, Canada, and (b) describe glycated haemoglobin (HbA1c) trajectories in the first 12 months after initiation of pharmacotherapy, stratified by metformin usage pattern. MATERIALS AND METHODS:We conducted a retrospective cohort study using linked administrative datasets from 2012 to 2017 to define a cohort of individuals with uncomplicated incident type 2 diabetes. Using logistic regression, we determined individual and clinical characteristics associated with metformin discontinuation. We categorized individuals based on patterns of metformin use and then used mean HbA1c measurements over a 12-month follow-up period to determine glycaemic trajectories for each pattern. RESULTS:Characteristics associated with metformin discontinuation were younger age, lower baseline HbA1c and having fewer comorbidities. Sex, income and location (urban/rural) were not significantly associated with metformin discontinuation. Individuals who continued metformin with higher adherence and individuals who discontinued metformin entirely had lowest HbA1c values at 12 months from treatment initiation. Those who changed therapy or had additional therapies added had higher HbA1c values at 12 months. CONCLUSION:Identifying characteristics associated with discontinuation of metformin and individuals' medication usage patterns provide an opportunity for targeted interventions to support patients' glycaemic management.

Background The influence of fee‐for‐service reimbursement on cardiac imaging has not been compared with other payment models. Furthermore, variation in ordering practices is not well understood. Methods and Results This retrospective, population‐based cohort study using linked administrative data from Alberta, Canada included adults with chronic heart disease (atrial fibrillation, coronary artery disease, and heart failure) seen by cardiac specialists for a new outpatient consultation April 2012 to December 2018. Generalized linear mixed‐effects models estimated the association of payment model (including the ability to bill to interpret imaging tests) and the use of cardiac imaging and quantified variation in cardiac imaging. Among 31 685 adults seen by 308 physicians at 136 sites, patients received an observed mean of 0.67 (95% CI, 0.67–0.68) imaging tests per consultation. After adjustment, patients seeing fee‐for‐service physicians had 2.07 (95% CI, 1.68–2.54) and fee‐for‐service physicians with ability to interpret had 2.87 (95% CI, 2.16–3.81) times the rate of receiving a test than those seeing salaried physicians. Measured patient, physician, and site effects accounted for 31% of imaging variation and, following adjustment, reduced unexplained site‐level variation 40% and physician‐level variation 29%. Conclusions We identified substantial variation in the use of outpatient cardiac imaging related to physician and site factors. Physician payment models have a significant association with imaging use. Our results raise concern that payment models may influence cardiac imaging practice. Similar methods could be applied to identify the source and magnitude of variation in other health care processes and outcomes.

Background: Choosing Wisely Canada (CWC) recommends avoiding noninvasive advanced cardiac testing (e.g., exercise stress testing [EST], echocardiography and myocardial perfusion imaging [MPI]) for preoperative assessment in patients scheduled to undergo low-risk noncardiac surgery. In this study, we assessed the temporal trends in testing, overlapping with the introduction of the CWC recommendations in 2014, and patient and provider factors associated with low-value testing. Methods: In this population-based retrospective cohort study, we used linked health administrative data in Alberta, Canada, to identify adult patients who underwent elective noncardiac surgery between Apr. 1, 2011, and Mar. 31, 2019, who had preoperative noninvasive advanced cardiac tests (EST, echocardiography or MPI) within 6 months before surgery. We included electrocardiography as an exploratory outcome. We excluded patients at high risk using the Revised Cardiac Risk Index (score ≥ 1 considered to indicate high risk), and modelled patient and temporal factors associated with the number of tests. Results: We identified 1 045 896 elective noncardiac operations performed in 798 599 patients and 25 599 advanced preoperative cardiac tests; 2.1% of operations were preceded by advanced cardiac testing. The incidence of testing increased over the study period, and, by 2018/19, patients were 1.3 times (95% confidence interval 1.2–1.4) more likely to receive a preoperative advanced test compared to 2011/12. Urban patients were more likely to receive a preoperative advanced cardiac test than their rural counterparts. Electrocardiography was the most common preoperative cardiac test, preceding 182 128 procedures (17.4%). Interpretation: Preoperative advanced cardiac testing was infrequent in adult Albertans who underwent low-risk elective noncardiac operations. Despite CWC recommendations, the use of some tests appears to be increasing, and there was substantial variation across geographic areas.

Background: One in eight people with heart disease has poor medication adherence that, in part, is related to copayment costs. This study tested whether eliminating copayments for high-value medications among low-income older adults at high cardiovascular risk would improve clinical outcomes. Methods: This randomized 2×2 factorial trial studied 2 distinct interventions in Alberta, Canada: eliminating copayments for high-value preventive medications and a self-management education and support program (reported separately). The findings for the first intervention, which waived the usual 30% copayment on 15 medication classes commonly used to reduce cardiovascular events, compared with usual copayment, is reported here. The primary outcome was the composite of death, myocardial infarction, stroke, coronary revascularization, and cardiovascular-related hospitalizations over a 3-year follow-up. Rates of the primary outcome and its components were compared using negative binomial regression. Secondary outcomes included quality of life (Euroqol 5-dimension index score), medication adherence, and overall health care costs. Results: A total of 4761 individuals were randomized and followed for a median of 36 months. There was no evidence of statistical interaction ( P =0.99) or of a synergistic effect between the 2 interventions in the factorial trial with respect to the primary outcome, which allowed us to evaluate the effect of each intervention separately. The rate of the primary outcome was not reduced by copayment elimination, (521 versus 533 events, incidence rate ratio 0.84 [95% CI, 0.66–1.07], P =0.162). The incidence rate ratio for nonfatal myocardial infarction, nonfatal stroke, and cardiovascular death (0.97 [95% CI, 0.67–1.39]), death (0.94 [95% CI, 0.80 to 1.11]), and cardiovascular-related hospitalizations (0.78 [95% CI, 0.57 to 1.06]) did not differ between groups. No significant between-group changes in quality of life over time were observed (mean difference, 0.012 [95% CI, –0.006 to 0.030], P =0.19). The proportion of participants who were adherent to statins was 0.72 versus 0.69 for the copayment elimination versus usual copayment groups, respectively (mean difference, 0.03 [95% CI, 0.006–0.06], P =0.016). Overall adjusted health care costs did not differ ($3575 [95% CI, –605 to 7168], P =0.098). Conclusions: In low-income adults at high cardiovascular risk, eliminating copayments (average, $35/mo) did not improve clinical outcomes or reduce health care costs, despite a modest improvement in adherence to medications.

Surveillance of stage IV colorectal cancer (CRC) after curative-intent metastasectomy can be effective for detecting asymptomatic recurrence. Guidelines for various forms of surveillance exist but are supported by limited evidence. We aimed to determine the most cost-effective strategy for surveillance following curative-intent metastasectomy of stage IV CRC. We performed a decision analysis to compare four active surveillance strategies involving clinic visits and investigations elicited from National Comprehensive Cancer Network (NCCN) recommendations. Markov model inputs included data from a population-based cohort and literature-derived costs, utilities, and probabilities. The primary outcomes were costs (2021 Canadian dollars) and quality-adjusted life years (QALYs) gained. Over a 10-year base-case time horizon, surveillance with follow-ups every 12 months for 5 years was most economically favourable at a willingness-to-pay threshold of CAD 50,000 per QALY. These patterns were generally robust in the sensitivity analysis. A more intensive surveillance strategy was only favourable with a much higher willingness-to-pay threshold of approximately CAD 425,000 per QALY, with follow-ups every 3 months for 2 years then every 12 months for 3 additional years. Our findings are consistent with NCCN guidelines and justify the need for additional research to determine the impact of surveillance on CRC outcomes.

Background: Self-management education and support (SMES) interventions have modest effects on intermediate outcomes for those at risk of cardiovascular disease, but few studies have measured or demonstrated an effect on clinical end points. Advertising for commercial products is known to influence behavior, but advertising principles are not typically incorporated into SMES design. Methods: This randomized trial studied the effect of a novel tailored SMES program designed by an advertising firm among a population of older adults with low income at high cardiovascular risk in Alberta, Canada. The intervention included health promotion messaging from a fictitious “peer” and facilitated relay of clinical information to patients’ primary care provider and pharmacist. The primary outcome was the composite of death, myocardial infarction, stroke, coronary revascularization, and hospitalizations for cardiovascular-related ambulatory care–sensitive conditions. Rates of the primary outcome and its components were compared using negative binomial regression. Secondary outcomes included quality of life (EQ-5D [EuroQoL 5-dimension] index score), medication adherence, and overall health care costs. Results: We randomized 4761 individuals, with a mean age of 74.4 years, of whom 46.8% were female. There was no evidence of statistical interaction (P=0.99) or of a synergistic effect between the 2 interventions in the factorial trial with respect to the primary outcome, which allowed us to evaluate the effect of each intervention separately. Over a median follow-up time of 36 months, the rate of the primary outcome was lower in the group that received SMES compared with the control group (incidence rate ratio, 0.78 [95% CI, 0.61 to 1.00]; P=0.047). No significant between-group changes in quality of life over time were observed (mean difference, 0.0001 [95% CI, −0.018 to 0.018]; P=0.99). The proportion of participants who were adherent to medications was not different between the 2 groups (P=0.199 for statins and P=0.754 for angiotensin-converting enzyme inhibitors/angiotensin receptor blockers). Overall adjusted health care costs did not differ between those receiving SMES and the control group ($2015 [95% CI, −$1953 to $5985]; P=0.320). Conclusions: For older adults with low income, a tailored SMES program using advertising principles reduced the rate of clinical outcomes compared with usual care. The mechanisms of improvement are unclear and further studies are required. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT02579655.

BACKGROUND Alert-driven remote patient monitoring (RPM) or fully virtual care without routine evaluations may reduce clinic workload and promote more efficient resource allocation, princi-pally by diminishing nonactionable patient encounters.OBJECTIVE The purpose of this study was to conduct a cost- consequence analysis to compare 3 postimplant implantable cardioverter-defibrillator (ICD) follow-up strategies: (1) in-person evaluation (IPE) only; (2) RPM-conventional (hybrid of IPE and RPM); and (3) RPM-alert (alert-based ICD follow-up).METHODS We constructed a decision-analytic Markov model to es-timate the costs and benefits of the 3 strategies over a 2-year time horizon from the perspective of the US Medicare payer. Aggregate and patient-level data from the TRUST (Lumos-T Safely RedUceS RouTine Office Device Follow-up) randomized clinical trial informed clinical effectiveness model inputs. TRUST randomized 1339 pa-tients 2:1 to conventional RPM or IPE alone, and found that RPM was safe and reduced the number of nonactionable encounters. Cost data were obtained from the published literature. The primary outcome was incremental cost. RESULTS Mean cumulative follow-up costs per patient were $12,688 in the IPE group, $12,001 in the RPM-conventional group, and $11,011 in the RPM-alert group. Compared to the IPE group, both the RPM-conventional and RPM-alert groups were associated with lower incremental costs of -$687 (95% confidence interval [CI] -$2138 to 1$638) and -$1,677 (95% CI -$3134 to-$304), respec-tively. Therefore, the RPM-alert strategy was most cost-effective, with an estimated cost-savings in 99% of simulations.CONCLUSIONS Alert-driven RPM was economically attractive and, if patient outcomes and safety are comparable to those of conven-tional RPM, may be the preferred strategy for ICD follow-up.

Objectives: Our aim in this study was to describe patterns and patient-level factors associated with use of sodium-glucose cotransporter-2 inhibitors (SGLT2is) among adults with diabetes being treated in Alberta, Canada.Methods: Using linked administrative data sets from 2014 to 2019, we defined a retrospective cohort of adults with prevalent or incident type 2 diabetes with indications for SGLT2i use and who did not have advanced kidney disease (glomerular filtration rate <30 mL/min per 1.73 m2) or previous amputation. We describe medication dispensation patterns of SGLT2is over time in the overall cohort and among the subgroup with cardiovascular disease (CVD). Multivariable logistic regression was used to determine patients' characteristics associated with SGLT2i use.Results: Of the 341,827 patients with diabetes (mean age, 60.7 years; 45.6% female), 107,244 (31.3%) had CVD. The proportion of patients with an SGLT2i prescription increased in a linear fashion to a maximum of 10.8% (95% confidence interval [CI], 10.7% to 10.9%) of the eligible cohort by the end of the observation period (March 2019). The proportion of filled prescriptions was similar for patients with CVD (10.4%; 95% CI, 10.1% to 10.6%) and for those without CVD (10.9%; 95% CI, 10.8% to 11.0%). Patients' characteristics associated with lower odds of filling an SGLT2i prescription included female sex, older age and lower income.Conclusions: The use of SGLT2is is increasing among patients with diabetes but remains low even in those with CVD. Policy and practice changes to increase prescribing, especially in older adults, may help to reduce morbidity and mortality related to cardiovascular and renal complications.(c) 2022 Canadian Diabetes Association.

Caring for patients with AF is expensive. Estimated costs account for up to 3% of total annual heath care expenditure in many developed nations. Due to an aging population, the clinical and economic burden is expected to increase over the next decade. There are limited contemporary economic data to facilitate the development of cost-efficient strategies for improving the quality of AF care.

Canadian guidelines recommend metformin as first-line therapy for incident uncomplicated type 2 diabetes, and, in the Albertan context, initial metformin monotherapy prescription rates are 89%. However, only 54% to 65% remain on treatment after 1 year, with highest discontinuation rates within the first 3 months.

Introduction: Current implementation of remote patient monitoring (RPM) for implantable cardioverter defibrillators (ICDs) involves a hybrid of remote assessment and in-person evaluation (IPE) every 3 months. Alert-driven RPM or fully virtual care without routine visits may reduce non-actionable patient evaluation, increased clinic workload and inefficient resource allocation. Objective: To conduct a cost-consequence analysis to compare three patient management strategies following ICD implantation: (a) IPE only, (b) RPM-conventional (hybrid of IPE and RPM), and (c) RPM-alert (alert-based ICD follow up). Methods: We constructed a decision-analytic Markov model to estimate the costs and benefits of three strategies of patient management following ICD implantation over a two-year time horizon from the perspective of the US healthcare system. Aggregate and patient-level data from the TRUST (Lumos-T Safely RedUceS RouTine Office Device Follow-up) clinical trial informed clinical effectiveness model inputs. TRUST randomized 1339 patients 2:1 to conventional RPM or IPE alone, and found that RPM was safe and reduced the number of non-actionable encounters. Cost data was obtained from the published literature. The primary outcome was incremental cost. Results: The mean cumulative costs per patient were $12,688 in the IPE group, $12,001 in the RPM-conventional group, and $11,011 in the RPM-alert group. Compared to the IPE group, both the RPM-conventional and RPM-alert groups were associated with lower incremental costs of -$687 (95% confidence interval (CI)-$2,138 to +$638) and -$1,677 (95% CI -$3,134 to -$304), respectively. Of the three groups, the RPM-alert strategy was the most cost-effective strategy with an estimated cost-savings in 99% of simulations. Conclusions: Alert-driven RPM was economically attractive and, if patient outcomes and safety are comparable to conventional RPM, may be the preferred strategy of patient follow up.

Background: Assessment of potential geographic variation in quality indicators of atrial fibrillation care may identify opportunities for improvement in the quality of atrial fibrillation care. The objective of this study was to assess for potential geographic variation in the quality of atrial fibrillation care in Alberta, Canada. Methods: In a population-based cohort of adults (age ≥ 18 yr) with incident nonvalvular atrial fibrillation (NVAF) diagnosed between Apr. 1, 2008, and Mar. 31, 2016, in Alberta, we investigated the variation in national quality indicators of atrial fibrillation care developed by the Canadian Cardiovascular Society. Specifically, we assessed the geographic and temporal variation in the proportion of patients with initiation of oral anticoagulant therapy, persistence with therapy, ischemic stroke and major bleeding outcomes 1 year after atrial fibrillation diagnosis using linked administrative data sets. We defined stroke risk using the CHADS2 score. We assessed geographic variation using small-area variation statistics and geospatial data analysis. Results: Of the 64 093 patients in the study cohort (35 019 men [54.6%] and 29 074 women [45.4%] with a mean age of 69 [standard deviation 15.9] yr), 36 199 were at high risk for stroke and 14 411 were at moderate risk. Within 1 year of NVAF diagnosis, 20 180 patients (55.7%) in the high-risk group and 6448 patients (44.7%) in the moderate-risk group were prescribed anticoagulation. A total of 2187 patients (3.4%) had an ischemic stroke, and 2996 patients (4.7%) experienced a major bleed. There was substantial regional variation observed in initiation of oral anticoagulant therapy but not in the proportion of patients with ischemic stroke or major bleeding. Among the 64 Health Status Areas in Alberta, therapy initiation rates ranged from 22.6% to 71.2% among patients at high stroke risk and from 22.7% to 55.8% among those at moderate stroke risk, with clustering of lower therapy initiation rates in rural northern regions. Interpretation: The rate of initiation of oral anticoagulant therapy among adults with incident atrial fibrillation was less than 60% in patients in whom oral anticoagulant therapy would be considered guideline-appropriate care. The large geographic variation in oral anticoagulant prescribing warrants additional study into patient, provider and health care system factors that contribute to variation and drive disparities in high-quality, equitable atrial fibrillation care.

To use real-world prescription data from Alberta, Canada to describe patterns and patient-level predictors of the uptake of SGLT2 inhibitors (SGLT2i).

BACKGROUND:A range of first-line similarly effective medications ranging in price are recommended for treating uncomplicated hypertension. Considering drug costs alone, thiazides and thiazide-like diuretics are the most cost-efficient option. We determined incident prescribing of thiazides for newly diagnosed hypertension as first-line treatment in Alberta, factors that predicted receiving thiazides vs more costly medications, and how much could be saved if more patients were prescribed thiazides.METHODS:Using a retrospective cohort design, factors predicting receiving thiazides vs other agents were determined using mixed effects logistic regression. Cost savings were simulated by shifting patients from other antihypertensive medications to thiazides and calculating the difference.RESULTS:Within our cohort of 89,548 adults, only 12% received thiazides as first-line treatment whereas 44% received angiotensin converting enzyme inhibitors, 17% received angiotensin receptor blockers, 16% received calcium channel blockers, and 10% received β-blockers. Antihypertensive medications were typically prescribed by office-based, general practitioners (88%). Being male and receiving a prescription from a physician with ≥ 20 years of practice and a high clinical workload were associated with increased odds of receiving nonthiazides. In the extreme case that all patients received thiazides as their first prescription, spending would have been reduced by a maximum of 95% (CAD$1.8 million).CONCLUSIONS:Only 12% of Albertan adults with incident, uncomplicated hypertension were prescribed thiazides as first-line treatment. With the opportunity for drug cost savings, future research should evaluate the risk of adverse events and side effects across the drug classes and whether the costs associated with managing those risks could offset the savings achieved through increased thiazide use.

To use real‐world prescription data from Alberta, Canada to: (a) describe the prescribing patterns for initial pharmacotherapy for those with newly diagnosed uncomplicated type 2 diabetes; (b) describe medication‐taking behaviours (adherence and persistence) in the first year after initiating pharmacotherapy; and (c) explore healthcare system costs associated with prescribing patterns.

Physician payment models are perceived to be an important strategy for improving health, access, quality, and the value of health care. Evidence is predominantly from primary care, and little is known regarding whether specialists respond similarly. We conducted a systematic review to synthesize evidence on the impact of specialist physician payment models across the domains of health care quality; clinical outcomes; utilization, access, and costs; and patient and physician satisfaction. We searched Medline, Embase, and six other databases from their inception through October 2018. Eligible articles addressed specialist physicians, payment models, outcomes of interest, and used an experimental or quasi-experimental design. Of 11,648 studies reviewed for eligibility, 11 articles reporting on seven payment reforms were included. Fee-for-service (FFS) was associated with increased desired utilization and fewer adverse outcomes (in the case of hemodialysis patients) and better access to care (in the case of emergency department services). Replacing FFS with capitation and salary models led to fewer elective surgical procedures (cataracts and tubal ligations) and, with an episode-based model, appeared to increase the use of less costly resources. Four of the seven reforms met their goals but many had unintended consequences. Payment model appears to affect utilization of specialty care, although the association with other outcomes is unclear due to mixed results or lack of evidence. Studies of salary and salary-based reforms point to specialists responding to some incentives differently than theory would predict. Additional research is warranted to improve the evidence driving specialist payment policy. (C) 2020 Elsevier B.V. All rights reserved.

Background: Erythropoiesis-stimulating agents including epoetin alfa have been a mainstay of anemia management in patients with chronic kidney disease. Although the standard practice has been to administer epoetin alfa to patients on hemodialysis (HD) intravenously (IV), subcutaneous (SQ) epoetin alfa is longer acting and achieve the same target hemoglobin level to be maintained at a reduced dose and cost. Objective: The primary objective of this study was to determine the economic benefits of change in route of epoetin alfa administration from IV to SQ in HD patients. The secondary objectives were (1) to determine the differences in epoetin alfa doses at the pre-switch (IV) and post-switch period (SQ) and (2) to determine serum hemoglobin concentration, transferrin saturation, ferritin level, IV iron dose and cost in relationship to route of epoetin alfa administration. Design: This retrospective observational study included patients who transitioned from IV to SQ epoetin alfa. Setting: Two HD sites in southern Saskatchewan (Regina General Hospital, and Wascana Dialysis Unit, Regina) and 2 sites in northern Saskatchewan (St. Paul’s [SPH] Hospital, and SPH Community Renal Health Center, Saskatoon). Patients: The study includes 215 patients who transitioned from IV to SQ and were alive at the end of 12-month follow-up period. Measurements: We calculated the dose and cost of different routes of epoetin alfa administration/patient month. Also, serum hemoglobin, markers of iron stores (transferrin saturation and ferritin), IV iron dose, and cost were determined in relation to route of epoetin alfa administration. Methods: Data were gathered from 6 months prior (IV) to 12 months after switching treatment to SQ. The paired t -test and Wilcoxon signed-rank test were used to compare variables between pre-switch (IV) and post-switch (SQ) period. Results: The median cost (interquartile range) of epoetin alfa/patient-month decreased from (CAD508.3 [CAD349-CAD900.8]) pre-switch (IV) to (CAD381.2 [CAD247-CAD681]) post-switch (SQ) ( P < .001), a decrease of 25%. The median epoetin alfa dose/patient-month reduced from (38 500 [25 714.3-64 166.5] international unit) pre-switch to (26 750.3 [17 362.6-48 066] IU) post-switch ( P < .001), a decrease of 30.51%. The mean hemoglobin concentration (± standard deviation) for patients in both periods remained stable (103.3 ± 9.2 vs 104.3 ± 13.3 g/L, P = .34) and within the target range. There were no significant differences in transferrin saturation, ferritin, and IV iron dose and cost between the 2 study periods. Limitations: We were unable to consistently obtain information across all the sites on hospitalizations, inflammatory markers, nutritional status, and gastrointestinal bleeding. In addition, as our study sample was subject to survival bias, we cannot generalize our study results to other populations. Conclusions: We have shown that administering epoetin alfa SQ in HD patients led to a 30.51% reduction in dose and 25% reduction in cost while achieving equivalent hemoglobin levels. Given the cost sparing advantages without compromising care while achieving comparable hemoglobin levels, HD units should consider converting to SQ mode of administration. Trial registration: The study was not registered on a publicly accessible registry as it was a retrospective chart review and exempted from review by the Research Ethics Board of the former Regina Qu’Appelle Health Region.
