ABSTRACT

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.

ABSTRACT

BACKGROUND: Despite the laparoscopic approach, patients can suffer moderate to severe pain following bariatric surgery. This randomized controlled double-blinded trial investigated the analgesic efficacy of ultrasound-guided transversus abdominis plane (TAP) blocks for laparoscopic gastric-bypass surgery. METHODS: Seventy patients undergoing laparoscopic gastric-bypass surgery were randomized to receive either bilateral ultrasound-guided subcostal TAP block injections after induction of general anesthesia or none. All patients received trocar insertion site local anesthetic infiltration and systemic analgesia. The primary outcome was cumulative opioid consumption (IV morphine equivalent) during the first 24 h postoperatively. Interval opioid consumption, pain severity scores, rates of nausea or vomiting, and rates of pruritus were measured during phase I recovery, and at 24 and 48 h postoperatively. RESULTS: There was no difference in cumulative opioid consumption during the first 24 h postoperatively between the TAP (32.2 mg [95% CI, 27.6-36.7]) and control (35.6 mg [95% CI, 28.6-42.5]; P = 0.41) groups. Postoperative opioid consumptions during phase I recovery and the 24-48-h interval were similar between groups, as were pain scores at rest and with movement during all measured intervals. The rates of nausea or vomiting and pruritus were equivalent. CONCLUSIONS: Bilateral TAP blocks do not provide additional analgesic benefit when added to trocar insertion site local anesthetic infiltration and systemic analgesia for laparoscopic gastric-bypass surgery.
