Abstract
- Venous thromboembolism (VTE) is an important cause of perioperative morbidity and death among patients with cancer. (1,2) Beginning pharmacologic thromboprophylaxis at the time of surgery and continuing until hospital discharge [...]<br />Background: Use of extended pharmacologic thromboprophylaxis after major abdominopelvic cancer surgery should depend on best-available scientific evidence and patients&apos; informed preferences. We developed a risk-stratified patient decision aid to facilitate shared decision-making and sought to evaluate its effect on decision-making quality regarding use of extended thromboprophylaxis. Methods: We enrolled patients undergoing major abdominopelvic cancer surgery at an acad mie tertiary care centre in this pre-post study. We evaluated change in decisional conflict, readiness to decide, decision-making confidence, and change in patient knowledge. Participants were provided the appropriate risk-stratified decision aid (according to their Caprini score) in either the preoperative or postoperative setting. A sample size calculation determined that we required 17 patients to demonstrate whether the decision aid meaningfully reduced decisional conflict. We used the Wilcoxon matched-pairs signed ranks test for interval scaled measures. Results: We included 17 participants. The decision aid significantly reduced decisional conflict (median decisional conflict score 2.37 [range 1.00-3.81] v. 1.3 [range 1.00-3.25], p < 0.01). With the decision aid, participants had high confidence (median 86.4 [range 15.91-100]) and felt highly prepared to make a decision (median 90 [range 55-100]). Median knowledge scores increased from 50% (range 0%-100%) to 75% (range 25%-100%). Conclusion: Our risk-stratified, evidence-based decision aid on extended thromboprophylaxis after major abdominopelvic surgery significantly improved decision-making quality. Further research is needed to evaluate the usability and feasibility of this decision aid in the perioperative setting. Contexte: L&apos;utilisation d&apos;une thromboprophylaxie pharmacologique prolong e apr s une chirurgie majeure pour cancer abdomino-pelvien doit reposer sur les meilleures donn es scientifiques existantes et les pr f rences des malades bien renseign s. Nous avons con u un outil d cisionnel stratifi selon le risque pour faciliter les prises de d cision partag es et nous avons voulu en mesurer l&apos;effet sur la qualit des prises de d cision relatives l&apos;utilisation de la thromboprophylaxie prolong e. M thodes: Pour cette tude avant-apr s, nous avons inscrit des malades soumis une chirurgie majeure pour cancer abdomino-pelvien dans un centre universitaire de soins tertiaires. Nous avons valu les diff rences aux plans du conflit d cisionnel, de l&apos; tat de pr paration la prise de d cision, du degr de confiance envers le processus d cisionnel, et du niveau de connaissances des malades. On a remis aux personnes participantes l&apos;outil d cisionnel appropri (selon leur score de risque de Caprini) l&apos; tape pr - ou postop ratoire. Un calcul de la taille de l&apos; chantillon a permis de d terminer qu&apos;il nous fallait 17 personnes pour d montrer que l&apos;outil d cisionnel r duisait significativement le conflit d cisionnel. Nous avons utilis le test des rangs sign s de Wilcoxon pour paires appari es et mesures par chelle d&apos;intervalles. R sultats: Nous avons inclus 17 personnes. L&apos;outil d cisionnel a significativement r duit le conflit d cisionnel (indice m dian de conflit d cisionnel 2,37 [ ventail 1,00-3,81] c. 1,3 [ ventail 1,00-3,25], p < 0,01). Avec l&apos;outil d cisionnel, les personnes se sentaient tr s en confiance (m diane 86,4 [ ventail 15,91-100]) et se sentaient pr tes prendre leur d cision (m diane 90 [ ventail 55-100]). Les scores m dians de connaissances sont pass s de 50% ( ventail 0%-100%) 75% ( ventail 25%-100%). Conclusion: Notre outil d cisionnel stratifi selon le risque et fond sur des donn es probantes concernant l&apos;utilisation de la thromboprophylaxie prolong e apr s une chirurgie majeure pour cancer abdomino-pelvien a significativement am lior la qualit des prises de d cision. Il faudra approfondir la recherche pour valuer l&apos;applicabilit de cet outil d cisionnel en contexte p riop ratoire.
