The effectiveness of a multifaceted, group-facilitated audit and feedback intervention to increase tranexamic acid use during total joint arthroplasty.

PURPOSE: Intraoperative tranexamic acid (TXA) is used to reduce blood loss and the need for transfusions following total hip arthroplasty (THA) and total knee arthroplasty (TKA). Despite evidence in literature and local practice protocols supporting TXA as a part of standard of care for joint arthroplasty, TXA administration is underutilized. We aimed to use group-facilitated audit and feedback as the foundation of a knowledge translation strategy to increase TXA use for THA and TKA procedures. METHODS: Anesthesiologists consented to receive two data reports summarizing their individual rates of TXA use and postoperative blood transfusions compared with site peers. Variables collected included patient demographics, TXA usage, and the frequency and volume of red blood cell transfusions administered in the 72-hr postoperative period. The facilitated feedback session discussed report findings and focused on factors contributing to local practice patterns and opportunities for change. RESULTS: Tranexamic acid use increased for THA procedures at the intervention site from 66.6 to 74.4% (absolute change, 7.9%; 95% confidence interval [CI], 2.4 to 13.3). Likewise, TXA use for TKA procedures increased from 62.4 to 82.3% (absolute change, 19.9%; 95% CI 15.0 to 25.0). CONCLUSIONS: Physicians and their teams were able to review their practice data on TXA utilization, reflect on differences compared with evidence-based guidelines, discuss findings with peers, and identify opportunities for improvement. The intervention increased the use of TXA for both TKA and THA and shifted the dosage to better align with evidence-based practice guidelines.

RéSUMé: OBJECTIF : L'acide tranexamique (ATX) peropératoire est utilisé pour réduire les pertes sanguines et les besoins transfusionnels après les arthroplasties totales de la hanche (ATH) et du genou (ATG). Malgré les données probantes et les protocoles de pratique locaux appuyant l'utilisation d'ATX dans le cadre de la norme de soins en cas d'arthroplastie, l'administration de cet agent est sous-utilisée. Notre objectif était d'utiliser l'audit et la rétroaction facilités par le groupe comme base d'une stratégie d'application des connaissances afin d'accroître l'utilisation de l'ATX lors des ATH et ATG. MéTHODE: Les anesthésiologistes ont consenti à recevoir deux rapports de données résumant leurs taux individuels d'utilisation d'ATX et de transfusions sanguines postopératoires par rapport à leurs pairs au sein du même établissement. Les variables recueillies comprenaient les données démographiques des patients, l'utilisation d'ATX et la fréquence et le volume des transfusions d'érythrocytes administrées au cours d'une période postopératoire de 72 heures. La séance de rétroaction facilitée a porté sur les conclusions du rapport et s'est concentrée sur les facteurs contribuant aux habitudes de pratique locales et aux possibilités de changement. RéSULTATS: L'utilisation d'acide tranexamique a augmenté pour les procédures d'ATH au site d'intervention, passant de 66,6 % à 74,4 % (variation absolue, 7,9 %; intervalle de confiance [IC] à 95 %, 2,4 à 13,3). De même, l'utilisation d'ATX pour les procédures d'ATG est passée de 62,4 % à 82,3 % (variation absolue, 19,9 %; IC 95 %, 15,0 à 25,0). CONCLUSION: Les médecins et leurs équipes ont pu passer en revue leurs données de pratique sur l'utilisation d'ATX, réfléchir aux différences par rapport aux lignes directrices fondées sur des données probantes, discuter des résultats avec leurs pairs et identifier les possibilités d'amélioration. L'intervention a augmenté l'utilisation d'ATX pour l'ATG et l'ATH et a modifié la posologie pour mieux s'aligner sur les lignes directrices de pratique fondées sur des données probantes.

Group-facilitated audit and feedback to improve bronchiolitis care in the emergency department.

OBJECTIVE: Despite strong evidence recommending supportive care as the mainstay of management for most infants with bronchiolitis, prior studies show that patients still receive low-value care (e.g., respiratory viral testing, salbutamol, chest radiography). Our objective was to decrease low-value care by delivering individual physician reports, in addition to group-facilitated feedback sessions to pediatric emergency physicians. METHODS: Our cohort included 3,883 patients ≤ 12 months old who presented to pediatric emergency departments in Calgary, Alberta, with a diagnosis of bronchiolitis from April 1, 2013, to April 30, 2018. Using administrative data, we captured baseline characteristics and therapeutic interventions. Consenting pediatric emergency physicians received two audit and feedback reports, which included their individual data and peer comparators. A multidisciplinary group-facilitated feedback session presented data and identified barriers and enablers of reducing low-value care. The primary outcome was the proportion of patients who received any low-value intervention and was analysed using statistical process control charts. RESULTS: Seventy-eight percent of emergency physicians consented to receive their audit and feedback reports. Patient characteristics were similar in the baseline and intervention period. Following the baseline physician reports and the group feedback session, low-value care decreased from 42.6% to 27.1% (absolute difference: -15.5%; 95% CI: -19.8% to -11.2%) and 78.9% to 64.4% (absolute difference: -14.5%; 95% CI: -21.9% to -7.2%) in patients who were not admitted and admitted, respectively. Balancing measures, such as intensive care unit admission and emergency department revisit, were unchanged. CONCLUSION: The combination of audit and feedback and a group-facilitated feedback session reduced low-value care for patients with bronchiolitis.

Estimating Urine Albumin-to-Creatinine Ratio from Protein-to-Creatinine Ratio: Development of Equations using Same-Day Measurements.

BACKGROUND: Urine albumin-to-creatinine ratio (ACR) and protein-to-creatinine ratio (PCR) are used to measure urine protein. Recent guidelines endorse ACR use, and equations have been developed incorporating ACR to predict risk of kidney failure. For situations in which PCR only is available, having a method to estimate ACR from PCR as accurately as possible would be useful. METHODS: We used data from a population-based cohort of 47,714 adults in Alberta, Canada, who had simultaneous assessments of urine ACR and PCR. After log-transforming ACR and PCR, we used cubic splines and quantile regression to estimate the median ACR from a PCR, allowing for modification by specified covariates. On the basis of the cubic splines, we created models using linear splines to develop equations to estimate ACR from PCR. In a subcohort with eGFR<60 ml/min per 1.73 m2, we then used the kidney failure risk equation to compare kidney failure risk using measured ACR as well as estimated ACR that had been derived from PCR. RESULTS: We found a nonlinear association between log(ACR) and log(PCR), with the implied albumin-to-protein ratio increasing from <30% in normal to mild proteinuria to about 70% in severe proteinuria, and with wider prediction intervals at lower levels. Sex was the most important modifier of the relationship between ACR and PCR, with men generally having a higher albumin-to-protein ratio. Estimates of kidney failure risk were similar using measured ACR and ACR estimated from PCR. CONCLUSIONS: We developed equations to estimate the median ACR from a PCR, optionally including specified covariates. These equations may prove useful in certain retrospective clinical or research applications where only PCR is available.

A Cost Analysis and Cost-Utility Analysis of a Community Pharmacist-Led Intervention on Reducing Cardiovascular Risk: The Alberta Vascular Risk Reduction Community Pharmacy Project (RxEACH).

BACKGROUND: A randomized trial (the Alberta Vascular Risk Reduction Community Pharmacy Project) showed that a community pharmacist-led intervention was efficacious for reducing cardiovascular (CV) risk. However, the cost of this strategy is unknown. OBJECTIVES: We examined the short- and long-term cost of a pharmacist-led intervention to reduce CV risk compared to usual care. METHODS: We conducted a trial-based cost analysis from the perspective of a publicly funded healthcare system. Over 3 and 12 months of follow-up, we examined specific intervention costs (pharmacy claims), related intervention costs (laboratory tests and medications), and ongoing healthcare costs (physician claims, emergency department visits, and hospital admissions). We also used the validated CV Disease Policy Model-Canada to estimate the long-term effects. RESULTS: A total of 684 participants (mean age 62, 57% male) were included. Overall, there were no significant differences in healthcare costs at 3 or 12 months between the usual care and intervention groups (P = .127). The CV disease-related healthcare cost of managing a patient over a lifetime was estimated to be Can$45 530 (95% uncertainty interval [UI], 45 460-45 580) and Can$40 750 (95% UI, 37 780-43 620) in usual care and intervention groups, respectively, an incremental cost savings of Can$4770 per patient (95% UI, 1900-7760). The intervention dominated usual care (better outcomes and lower costs) across 3-year, 5-year, 10-year, and lifetime horizons. CONCLUSION: This economic analysis suggests that a clinical pathway-driven pharmacist-led intervention (previously shown to reduce CV risk) was associated with similar measured healthcare costs over 1 year, and lower extrapolated healthcare costs over a patient lifetime. This strategy could be broadly implemented to realize its benefits.
