Abstract Objective To test the effectiveness of a surgical web‐based decision aid (DA) in improving knowledge. Summary of Background Data DAs support decision making by providing information about the options. Methods A stepped wedge trial was conducted in 10 National Cancer Institute Community Oncology Research Program clinics (Alliance for Clinical Trials in Oncology). Clinics were randomized to time of transition from usual care (UC) to delivery of a web‐based DA. Patients with stage 0 through 3 breast cancer being considered for surgery were enrolled. Knowledge (primary outcome) was measured using the Breast Cancer Surgery Decision Quality Instrument and patients were asked, “How informed do you feel?” Intervention effects were tested with linear mixed‐effects models, accounting for surgeon and clinic‐level clustering, time, and enrollment after COVID. Additional models controlled for demographics. Results A total of 44% of DA arm patients reviewed the DA and 58% in UC arm reported reviewing “any information.” Being in the DA arm versus UC was not associated with knowledge. However, “review of information” was associated with higher knowledge. In addition, non‐White race and lower education were associated with lower knowledge. The DA arm was associated with higher perceptions of feeling informed (parameter estimate 1.36; 95% CI, 0.18–2.55; p = .02); this persisted even when controlling for review of information or demographics. Conclusion Improved knowledge was not demonstrate with a web‐based DA versus UC. Interestingly, the DA was associated with a higher likelihood of feeling informed. Future research will explore the discrepancy between patients feeling informed but having low knowledge, especially for disadvantaged patients.

370 Background: Mounting evidence suggests tailored preparation targeting geriatric vulnerabilities can improve functional outcomes after major surgery in older adults. Although many surgeons express interest in surgical optimization of older patients, few practices have the time or expertise to deliver geriatric prehabilitation before surgery. This study investigated the effectiveness of OPTI-Surg, a frailty prehabilitation toolkit, for improving surgical outcomes. In this abstract, we report adherence to the OPTI-Surg toolkit in the intervention arm. Methods: Thoracic (T), gastrointestinal (GI), and urologic (GU) oncological surgery practices affiliated with NCI’s Community Oncology Research Program (NCORP) were randomized 1:1:1, stratified by practice type, to usual care (control), OPTI-Surg toolkit, or OPTI-Surg with an implementation coach. The toolkit was implemented at the practice level and consisted of the 12-item Edmonton Frail Scale (EFS) and guided recommendations for interventions including referrals directed at identified vulnerabilities. Eligible patients were ≥70 years old and undergoing curative intent surgery for T, Gl, or GU cancers. Results: From July 2019 to October 2021, 155 patients were enrolled in the OPTI-Surg intervention arm. The EFS was administered to 153 (98.7%) of the enrolled patients, 143 of whom went on to have surgery. Overall, 134 (93.7%) surgical patients had at least one deficit identified on the EFS assessment and 55 (41.0%) of these patients received a recommended referral intended to optimize surgical outcomes. Among the 55 patients who received referrals, 44 (80.0%) followed through on the referral. Individual deficit rates were highest for medication use, general health status, and functional performance, and referrals were most frequently made for deficits in continence and functional independence (Table). Conclusions: In the OPTI-Surg geriatric surgical optimization trial, implementation of the frailty screening with the EFS assessment was successful. Rates of recommended referrals for patients with identified deficits, however, were low. When referred, most patients followed through for targeted prehabilitation.

314 Background: In a recent trial, we observed no statistically significant increase in engagement after a web-based decision aid (DA) was delivered to breast cancer patients prior to a surgical consult. However, a minority of the intervention group (44%) reviewed the DA. The objective is to assess the effect of the DA on engagement for the cohort of patients who reviewed it. Methods: A stepped wedge trial was conducted with 10 NCI Community Oncology Research Program clinics that care for a high proportion of socioeconomically disadvantaged patients (6/2019-12/2021). Clinics were randomized to time of transition from usual care (UC) to delivery of a DA. Patients with stage 0-3 breast cancer eligible for surgery provided consent prior to a surgical consult. Engagement was measured from audio-recorded surgical consults (Active Patient Behaviors, Street protocol). For this analysis, we identified a cohort of treatment compliant (TC) patients who reviewed the DA. Intervention effects comparing TC and UC groups were tested with linear mixed-effects models, accounting for time, enrollment post-COVID, and patient age, race, education, and socioeconomic disadvantage (assessed with Area Deprivation Index and dichotomized). Exploratory models were generated using Active Patient Behavior subcomponents (asking questions, assertive responses, expressions of concern) as the outcome. Results: The cohort includes 407 patients (UC 264; TC 143). TC patients were more likely to be white (TC 73%, UC 64%, p=0.03), have a college degree (TC 65%, UC 55%, p=0.05), and not be disadvantaged (TC 89%, UC 72%, p=0.001). TC was associated with increased engagement (8.2 [0.08, 16.2], p=0.048, Table). A college degree was associated with higher, while black race and socioeconomic disadvantage lower, engagement. On exploratory analyses, TC had a stronger association with higher levels of assertive responses (2.9 [-0.3, 6.1], p=0.07) compared with asking questions (5.2 [-1.4, 11.9], p=0.12) or expressions of concern (0.08 [-0.60, 0.76], p=0.82). Conclusions: We observed increased engagement in breast cancer patients who reviewed a DA prior to a surgical consult. However, we also observed differences based on race, education, and socioeconomic disadvantage. Further research will identify adjunct interventions to combine with the DA to improve cancer care delivery for diverse populations.

6520 Background: Increased patient engagement in decision making may mitigate disparities in breast cancer surgical care. Socioeconomically disadvantaged patients disproportionately experience barriers to engagement. Decision aids (DA) increase engagement by providing information, establishing role expectations during the consult, and increasing confidence in surgeon interactions. The objective was to test the effectiveness of a surgical web-based DA in increasing engagement among breast cancer patients in clinics that care for a high proportion of socioeconomically disadvantaged patients. Methods: A stepped wedge trial was conducted with 10 NCI Community Oncology Research Program clinics (Alliance for Clinical Trials in Oncology Research Base, 6/19-12/21). Clinics were randomized to time of transition from usual care (UC) to delivery of a web-based DA. Patients with stage 0-3 breast cancer eligible for surgery provided consent prior to a surgical consult. Socioeconomic disadvantage was assessed with the Area Deprivation Index measured at the zip+4 level and dichotomized. Patient engagement was measured by Patient’s Self-Efficacy in Patient-Physician Interactions (PEPPI-5, follow-up survey) and count of Active Patient Behaviors (Street protocol, audio recorded consult). Intervention effects were tested with linear mixed-effects models, accounting for surgeon and clinic-level clustering, time, and enrollment post-COVID. Heterogeneity of treatment effect by socioeconomic disadvantage was assessed with an interaction term. Results: 573 patients enrolled. 44% (136/309) reviewed the DA. No significant difference in engagement was observed comparing DA and UC for PEPPI-5 (-0.80 [95% CI -2.13, 0.54], p = 0.24) or Active Patient Behaviors (2.52 [CI -4.11, 9.15], p = 0.46). Enrollment post-COVID was associated with increased Active Patient Behaviors (9.59 [CI 1.76, 17.43], p = 0.02) but no change in PEPPI-5 (-1.31 [CI -2.88, 0.26], p = 0.10). No heterogeneity of treatment effect was observed. Conclusions: In this trial conducted in clinics that serve diverse populations, no significant relationship was observed between a web-based DA and patient engagement. Conducting this stepped wedge trial during the pandemic was challenging. Future analyses will explore the impact of COVID on outcomes and effect of the decision aid for patients who reviewed it.

1541 Background: Frailty is common in older adults undergoing major cancer surgery. Mounting evidence indicates multimodal interventions to optimize patient functional status by addressing vulnerabilities associated with frailty before surgery result in decreased complications and enhanced functional recovery. This study tested the effectiveness of OPTI-Surg, a surgical prehabilitation toolkit for improving surgical care and outcomes in older patients undergoing major cancer surgery. Here, we report results from the planned futility interim analysis (IA). Methods: Thoracic (T), gastrointestinal (GI), and urologic (GU) oncological surgery practices affiliated with NCI’s Community Oncology Research Program were randomized 1:1:1, stratified by practice type, to usual care (control), OPTI-Surg toolkit, or OPTI-Surg with an implementation coach. The toolkit was implemented at the practice level. It consisted of the 12-item Edmonton Frail Scale and guided recommendations for interventions directed at identified vulnerabilities. Eligible patients were adults ≥70 years old undergoing curative intent surgery for lung, gastrointestinal, or urologic cancers. Primary outcome was 8-week post-operative function (weekly caloric expenditure) derived from the validated Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire. A linear mixed model was used to compare usual care to the 2 OPTI-Surg arms combined, controlling for baseline function. Results: From July 2019 to October 2021, 225 patients, 50% of the total accrual goal, were enrolled from 29 practices, triggering the IA. Study was suspended to new patient accrual March to June 2020 due to the COVID-19 pandemic. There were no differences in demographics by arm (mean age 76.2 years; 46.4% women; 79.6% white; 20.4% lung resection, 69.8% major GI surgery, 9.8% total cystectomy). Of the 225 patients, 140 (47 Usual Care, 93 OPTI-Surg) were evaluable for the IA. There was no significant difference in post-operative function between OPTI-Surg and usual care (mean decrease of 0.59 kCal/week for OPTI-Surg patients and 0.19 kCal/week for usual care patients, p = 0.762, intraclass correlation = 0.033). Based on the futility analysis, the DSMB recommended closure of recruitment on September 16, 2022. Conclusions: Implementation of the OPTI-Surg toolkit did not significantly improve functional outcomes 8 weeks after surgery for patients aged 70 and older undergoing major cancer surgery compared to usual care. Future analysis of implementation and ethnographic data may identify reasons why significant differences between the intervention and usual care arms were not observed, potentially including disruptions due to the COVID-19 pandemic.

104 Background: Lymphedema (LE), a side effect of BC treatment, affects 8%–56% of women. The study tested the effectiveness of an education only vs education + exercise intervention on LE incidence in a group randomized trial (NCT00376597) of 38 cooperative group sites. Methods: Newly diagnosed women with stage I-III BC were consented and arm circumference and range of motion were measured pre-surgery. After surgery, patients (pts) were enrolled based on the randomization assignment of their treating institution, stratified by their type of node dissection (sentinel or axillary), and received either: education only: its causes, signs, symptoms and risk reduction strategies, or education + personalized exercise instruction from a physical therapist, with elastic compression garments to wear during heavy arm use and air travel. Pts completed surveys and arm measurements at baseline (BL), 12 and 18 months with the LE endpoint defined as ≥ 10% difference in limb volume at any time from BL to 18 months or physician diagnosis of LE. Cochran-Mantel-Haenszel (CMH) tests were used to compare the LE-free rate between arms, adjusted for type of biopsy. Logistic regression assessed predictors of LE. Results: 568 pts were enrolled, 45% in education only, and 55% in education + exercise, with 554 (98%) included in the analyses. Pts were on average 57.7 years, White (83%), non-Hispanic (92%) and married (62%). 47% only had sentinel node dissection, 35% had mastectomy, and 37% had chemotherapy. The LE-free rate was 58% in education only vs 55% in education + exercise (CMH p = 0.73). Predictors of LE included surgery type (lumpectomy vs mastectomy, OR = 2.22, p < 0.001) and chemotherapy (no vs yes, OR = 1.73, p = 0.02), after adjusting for BMI and type of node dissection. Only one-third wore the sleeve at least 75% of the time and only 50% did LE exercises at least weekly. Conclusions: There was no difference by intervention arm in LE incidence by 18 months. Poor adherence in the education + exercise arm may have been a factor. Additional analyses will assess quality of life, body image and knowledge about LE by arm. Further research is needed to effectively prevent LE in pts after BC surgery. Research Support: UL1TR001409; U10CA037447, UG1CA189823 Clinical trial information: NCT00376597.
