Avoiding the needle: A quality improvement program introducing apixaban for extended thromboprophylaxis after major gynecologic cancer surgery.

OBJECTIVE: Patients undergoing gynecologic cancer surgery at our centre are recommended up to 28 days of enoxaparin for extended post-operative thromboprophylaxis (EP). Baseline survey revealed 92% patient adherence, but highlighted negative effects on patient experience due to the injectable route of administration. We aimed to improve patient experience by reducing pain and bruising by 50%, increasing adherence by 5%, and reducing out-of-pocket cost after introducing apixaban as an oral alternative for EP. METHODS: In this interrupted time series quality improvement study, gynecologic cancer patients were offered a choice between apixaban (2.5 mg orally twice daily) or enoxaparin (40 mg subcutaneously once daily) at time of discharge. A multidisciplinary team informed project design, implementation, and evaluation. Process interventions included standardized orders, patient and care team education programs. Telephone survey at 1 and 6 weeks and chart audit informed outcome, process, and balancing measures. RESULTS: From August to October 2022, 127 consecutive patients were included. Apixaban was chosen by 84%. Survey response rate was 74%. Patients who chose apixaban reported significantly reduced pain, bruising, increased confidence with administration, and less negative impact of the medication (p < 0.0001 for all). Adherence was unchanged (92%). The proportion of patients paying less than $125 (apixaban cost threshold) increased from 45% to 91%. There was no difference in bleeding and no VTE events. CONCLUSIONS: Introduction of apixaban for EP was associated with significant improvement in patient-reported quality measures and reduced financial toxicity with no effect on adherence or balancing measures. Apixaban is the preferred anticoagulant for EP at our centre.

Serous tubal intraepithelial carcinoma (STIC) outcomes in an average risk population.

Objective: Serous tubal intraepithelial carcinoma (STIC) are precursors for high grade serous carcinomas (HGSC) of tubo-ovarian origin. It is a rare entity, most commonly described in patients with a BRCA pathogenic variant (PV) undergoing risk-reducing surgery. Little is known about the risk of subsequent HGSC in patients found to have an isolated STIC without a genetic PV. The objective of this study is to report the outcomes of STIC diagnosed in patients with negative genetic testing ("average risk"). Methods: Retrospective population-based cohort study from British Columbia, Canada. Chart review of patients diagnosed with an isolated STIC from January 2012 to May 2022. Average risk patients are defined as individuals with known negative genetic testing results. Treatment and outcomes are described in the "average risk", BRCA PV, and total cohorts. Results: Twenty-nine patients with isolated STIC were identified. Ten patients had a BRCA PV, four had other variants identified (BRIP1, MLH1, BRIP1 VUS, BRCA 2 VUS), nine had no PV identified ("average risk"), and six were unknown (no genetic testing). Of the nine "average risk" patients, eight (89%) underwent surgical staging. Three (33.3%) had subsequent HGSC diagnosed 29, 70 and 86 months after STIC diagnosis. Conclusions: STIC identified in patients with negative genetic testing are at risk of subsequent HGSC. Patients developed primary peritoneal HGSC despite surgical staging. These patients should also be included in future meta-analysis to determine outcomes and optimal treatment.

Paraneoplastic opsoclonus-myoclonus syndrome as a presentation of high grade serous ovarian cancer.

Opsoclonus-myoclonus syndrome (OMS) is a rare paraneoplastic disorder that is most often seen in association with pediatric neuroblastoma, breast cancer, small cell lung cancer, and prostate cancer. There are only three previously documented cases relating paraneoplastic OMS to ovarian cancer. We present a unique case of OMS related to a stage IIIC high grade serous ovarian carcinoma in a patient with germline BRCA2 mutation, with ten years of clinical follow up. This case report is presented to document the rare association of OMS with epithelial ovarian cancer. Additionally, in this case, OMS and epithelial cancer were successfully treated with medical therapy alone. This is the first report to our knowledge to document ten years of clinical follow up in this context, and to report that the association may not be evident at the time of ovarian cancer recurrence.

Readiness for Transition to Adult Health Care for Young Adolescents with Congenital Heart Disease.

This study evaluates transition readiness, medical condition knowledge, self-efficacy, and illness uncertainty in young adolescents (ages 12 to 15 years) with congenital heart disease (CHD), and medical, patient, and parental factors associated with transition readiness. We enrolled 82 patients with moderate or complex CHD (n = 36, 44% male; mean age 13.6 ± 1.3 years), and their parents. Patients completed standardized self-report measures: Transition Readiness Assessment Questionnaire (TRAQ), MyHeart scale, General Self-Efficacy scale, and Children's Uncertainty in Illness Scale. Parents completed the MyHeart scale and demographic information. Many young adolescents had not discussed transfer with a health care provider (n = 20, 24%) or parent (n = 34, 41%). Transition readiness was higher among patients who were older, more knowledgeable about their condition, had a history of primary cardiac repair and greater self-efficacy, and was lower for boys and patients on cardiac medications. Transition readiness was unrelated to CHD diagnosis and patients' illness uncertainty. Patients' self-advocacy skills were superior to their chronic disease self-management skills. Increased parental medical condition knowledge was positively correlated with patient knowledge, and patient-parent discussion of transfer was associated with increased patient's self-management skills. Transition is not uniformly discussed with young adolescent CHD patients. Parental involvement is correlated with increased transition readiness and patient disease self-management skills. Young adolescent transition programs should focus on education around improving patient medical condition knowledge, promote chronic disease self-management skills development, and include parental involvement.
