e18669 Background: Transfusion stewardship is a vital part of managing patients with hematologic malignancies (HM). Blood products are limited resources and blood product transfusion (txn) is costly and poses complications. Randomized trials in different clinical settings have shown that a conservative txn strategy is not inferior to more liberal txn strategy. As a result, the AABB and ASCO have recommended following a conservative txn strategy in patients with cancer (hemoglobin (hg) <7-8g/dL and platelets (plt) <10K in stable non-bleeding patients). Here we report our early outpatient institution’s experience implementing a contemporary txn approach in patients with HM. Methods: We formed a multi-disciplinary team to analyze blood product utilization. Overutilization was defined as orders for multi-units, packed red blood cells (pRBC) for hg >8 or plt for plt >10K in stable non-bleeding patients. Patients’ charts were audited during the baseline period to understand practice patterns. Data were collected using Qlik database. The baseline period (May 1, 2019-Feb 29, 2020) was compared to the intervention period (March 1 – December 31, 2020). A root cause analysis was performed. When possible 2-sided paired T-test was performed. If not possible, descriptive statistics were performed. Three interventions were developed and implemented sequentially: March 2020 – Blood bank began real-time review of blood products overutilization. May 2020 – Electronic Medical Record txn order set was revised to reflect recommended best practices. October 2020 –Txn guidelines revised for patients with HM. Results: During the study period, there were 3,227 pRBC and 2,817 plt transfused units in the outpatient setting. Monthly pRBC txn decreased from (mean(SD)) 168.5 (16.6) to 154.2(16.4) (p value: 0.14). Monthly plt txn decreased from 166.5 (26.5) to 115.2 (26.2) (p value: 0.001). Rates of multi-unit orders decreased significantly. Average monthly multi-unit orders decreased for pRBC (pre-48.6(5.9);post-24.3(7.6);p value 0.00007) and plts (pre-67.4(11.8);post-21.3(23.3);p value: 0.0002). Average hb at time of txn in the pre- and post-intervention period was 7.47 and 7.22. The percentage of txn in which the indication for txn was hb <7, 7-8, >8 changed from 34.6% to 56.3%, 52.6% to 32.8%, and 12.8% to 10.9% respectively. There was no significant increase in admissions for bleeding or increase in number of outpatient visits during the study period. Conclusions: Over 10-months, we significantly reduced outpatient blood product. Robust quality improvement methodology, engaging key stakeholders, and changing the culture of outpatient management were keys to success. To date, we have not seen any unintended consequences of these changes. These results are encouraging, as outpatient transfusion stewardship is thought to be harder given concerns about patients not being monitored as closely as in the inpatient setting.

e18676 Background: Oncology patients frequently experience acute physical symptoms related to cancer and its treatment. Management of symptoms is best accomplished using evidence-based clinical care. When implementing an advanced practice provider (APP)-led oncology acute care clinic, evidence-based clinical pathways were developed to ensure standardization among treating providers. Methods: The top ten emergency department admitting diagnoses for oncology patients identified by the Centers for Medicare and Medicaid Services provided the foundation for development of the clinical pathways. Relevant primary literature, National Comprehensive Cancer Center Network guidelines, and American Society of Clinical Oncology guidelines were reviewed for development of outpatient oncology acute care clinical pathways. The information was cross-referenced with institutional data to confirm applicability to the patient population. A multidisciplinary team including nursing, pharmacy, laboratory services, radiology, information technology, and administrative staff reviewed the workflow to ensure best processes. The pathways were reviewed by oncologists, APPs and pharmacists before finalization. Results: Nine evidence-based clinical pathways were developed by August 1, 2020. From August to December 2020, 165 patient visits took place in the outpatient oncology acute care clinic. Gastrointestinal manifestations (25%), hypovolemia/weakness (25%), and infections (17%) were the most frequently encountered symptoms. Evidence-based clinical pathways were followed for patients with a chief complaint with an associated algorithm (N=124). Conclusions: Implementation of clinical pathways facilitate best practice standardization when ordering labs, tests, and medications while enhancing the acceptance of the new service. The pathways will be reviewed and updated by a multidisciplinary team every 3 months to ensure current evidence-based practices. Semi-annual pathway audits have been implemented to evaluate utilization and optimize patient outcomes, as well as determine areas of improvement and growth. Areas of opportunity identified during the first pathway audit included creating pathways for cardiac disorders, mouth disorders, and infections unrelated to neutropenia. Additionally, order set integration to automate the clinical pathway process in the electronic medical record is in progress.[Table: see text]

Published: June 2021

e18685 Background: Health systems pressures during the COVID-19 pandemic have driven adoption of innovative models of cancer care which optimise resources and protect patients and staff. High-value changes should be identified and retained to improve resilience of cancer care. Methods: Cancer Australia reviewed the literature and consulted with oncology health professionals, cancer control experts and consumers to examine elements of cancer care that changed during the pandemic. Strategies that support high-value care and improve cancer outcomes were identified. Results: The pandemic highlighted models of care which minimise risk of infection for cancer patients, whilst optimising outcomes. Of the numerous cancer care elements that we examined, this abstract focuses on key enhancements in digital health and treatment practices. Digital health helped maintain quality and continuity of cancer care during the pandemic. Use of telehealth (for clinical and supportive care), e-prescribing, and e-ordering of investigations increased, supported by national health system funding. Shared care between care settings was facilitated by rapid uptake of telehealth, e-health records, virtual multidisciplinary team meetings and secure messaging. Treatment modifications included hypofractionated radiotherapy, transitioning to oral chemotherapy where possible, and home-based palliative care. Lower thresholds adopted for use of G-CSF with chemotherapy to reduce risk of febrile neutropenia, aimed to decrease hospital admission rates. It is important to address barriers to uptake of these high value changes. For digital health, variations in patient access to telehealth and digital health literacy can be reduced through technical and coordination support (tailored to people with diverse needs and backgrounds), with telehealth consultations offered in safe, accessible clinical or community settings. Administrative and technical burdens in health service settings can be mitigated through sustainable IT infrastructure, standardised processes for appointments, and improving staff digital health capabilities. Patient anxiety regarding changes in care plans can be mitigated through transparent, accessible, and culturally appropriate communication, documentation and shared decision-making. Clinician uncertainty in calculating risks and benefits in treatment modifications can be addressed through evidence-based standardised care procedures and risk-stratification protocols. Conclusions: Many modifications to cancer care made during the pandemic can have long-term benefits and should become standard care, including enhancements in digital health and treatment practices. Strategies have been identified which enable these changes and address barriers to uptake at the system-, service-, practitioner-, and patient-level. Efforts to embed high value changes are required across the cancer control sector.

e18687 Background: The long-acting injectable G-CSF, pegfilgrastim and its biosimilars have historically been given to patients 24 hours following the administration of myelosuppressive chemotherapy for either primary or secondary prophylaxis of febrile neutropenia (FN). Previous literature has indicated that pegfilgrastim administration prior to 24 hours post chemotherapy, may result in a deepened and prolonged neutropenia due to the increase in circulating granulocytes exposed to chemotherapy. With the onset of the COVID-19 pandemic and to reduce potential SAR-CoV-2 exposure to cancer patients on therapy, we implemented same day administration of injectable pegfilgrastim-cbqv among select breast cancer patients receiving myelosuppressive chemotherapy regimens from March 2020 – February 2021. Methods: Utilizing retrospective EHR chart reviews, 55 patients among 4 medical oncologists in our breast cancer group were identified as meeting the criteria of same day pegfilgrastim-cbqv administration. Inclusion was based on completion of at least 2 consecutive cycles of same day pegfilgrastim-cbqv 6 mg subcutaneous injection for primary or secondary prophylaxis. The selected patient charts were reviewed for the incidence and severity of FN. Among the patients who had documented FN, further subgroup analyses were done regarding baseline characteristics, timing of neutropenia, regimens, regimen sequence, and reported ADRs associated with pegfilgrastim-cbqv. Results: 9 (16.4%) of the 55 patients experienced FN (Grades 3-4) and 6 (10.9%) patients were hospitalized. There were no Grade 5 events and none had therapy discontinued due to FN. 8 (88.9%) of the patients experienced FN between cycles 1 and 2. Of note, there were no cases of COVID-19 among the 9 patients who had an episode of FN. 52 (94.5%) of the 55 patients received treatment with curative intent and 3 (5.5%) had metastatic disease on a subsequent line of therapy. The median age was 49.1 years (range 29-71) and patients were 56.4% Caucasian, 18.1% Black or African American, 12.7% Asian, and 12.7% Hispanic/Latina. Conclusions: Based on the retrospective data analysis, same day pegfilgrastim-cbqv appears to be a safe and effective option in the primary and secondary prophylaxis of FN with myelosuppressive standard of care chemotherapy used in breast cancer treatment. Though our review was limited by a relatively small sample size and confined to younger (49.1 median age) breast cancer patients, this opens the door to further re-evaluation of same day pegfilgrastim-cbqv administration in other patient populations. In a post pandemic treatment world, this slight change in practice has the potential to reduce patient financial toxicity associated with multiple medical visits, provide an alternative to on-body injector formulations, and ensure treatment adherence.

Published: June 2021

e18689 Background: While guidelines exist for appropriate use of chemotherapy in the metastatic setting based on performance status, such recommendations are less readily available for immune checkpoint inhibitors (ICIs). We sought to determine if there is a relationship between Eastern Cooperative Oncology Group (ECOG) performance status and outcomes on immunotherapy in patients treated for metastatic disease at our community-based oncology practice. Methods: 253 patients were identified as receiving nivolumab or pembrolizumab for stage IV malignancy at Cancer Centers of Colorado-SCL Health, between June 2018 and November 2020. Patients initiated on therapy after May 2020 were excluded from analysis, due to insufficient (less than 6 months) follow-up time. The remaining 183 patients were included in a retrospective cohort study comparing patients with ECOG 0, ECOG 1, and ECOG 2-4. Sex, age, type of cancer, and line of therapy were collected. Time on therapy was also calculated. Best response to therapy was determined (disease control or progressive disease). These baseline factors and outcomes were compared using ANOVA for numeric variables and chi-square tests of association for categorical variables. Time from initiation of ICI to death or hospice was also investigated and compared using a log-rank test. In addition, a multivariate Cox proportional hazards model was developed for the outcome, time to death/hospice, versus the predictors ECOG status, age, gender, and line of therapy. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated. Results: Of the 183 patients included in analysis, 31.7% had an ECOG of 0, 48.6% an ECOG of 1, and 19.7% an ECOG of 2-4. Non-small cell lung cancer and melanoma represented the majority of patients in each group. Gender and line of therapy did not differ between groups. There was a significant difference in age (p = 0.02) with mean age 62, 66, and 70 in ECOG 0,1, and 2-4, respectively. 54.6% of patients remained on therapy for at least 6 months (182 days), and there was no significant difference between groups in ability to complete 6 months of therapy (p = 0.32). For ECOG 0, 1, and 2-4, disease control was achieved in 67.2%, 59.6 %, and 41.7%, respectively (p = 0.048). Analysis of time to death/hospice with a log rank test and Kaplan Meier plot showed a significant difference between groups (p < 0.001). A multivariate Cox proportional hazards model revealed that patients with ECOG 0 had significantly longer time to death/hospice compared to patients in both other groups, after controlling for age, gender, and line of therapy (ECOG 1 vs. 0: HR 2.5, CI 1.27-4.9; ECOG 2-4 vs. 0: HR 2.83, CI 1.31-6.13). Conclusions: In this single institution retrospective study of patients receiving nivolumab or pembrolizumab for metastatic cancer, ECOG 0 was associated with disease control and increased time before death or transition to hospice.

Published: June 2021

e18691 Background: Increased rates of TE have been reported in patients (pts) with coronavirus disease (COVID-19), even without prior predisposition to thrombosis. Patients with cancer are already predisposed to a hypercoagulable state. We aimed to assess whether COVID-19 further increased the risk of TE in pts with active cancer at Montefiore Medical Center, Bronx, NY. Methods: The EMR of 90 cancer pts diagnosed with COVID-19 from March 15th to April 10th, 2020 were reviewed. COVID-19 testing was performed by PCR of nasal swab samples. Active cancer was defined as disease treated <1 year. Reports of imaging studies performed <30 days of the COVID-19+ test, either for new symptoms or for other reasons, were reviewed for new arterial (ATE) and/or venous thromboses (VTE). Patient were followed for 30 days from the date of COVID-19+ test for development of TE, hospital length of stay (LOS) and mortality. Results: Of 90 pts, 11 (12.2%) were found to have 13 new TE within 30 days of COVID-19+ test, 8 (8.9%) arterial and 5 (5.6%) venous. Of the 8 ATE, 7 were new strokes and/or microvascular cerebral disease (MCD) and 1 was a spleen infarct (SI). Of the 5 VTE, 3 were deep venous thrombosis, 1 pulmonary embolism (PE) and 1 patient presented with a superficial VTE. Two patients had 2 new TE each; stroke/PE and MCD/SI, respectively. Peak D-dimer (DD) value was higher in the TE group; mean DD (SD), TE vs no TE, 7.1 (3.4) vs 6.4 (7) ug/mL, p=0.03. Pts on either prophylactic or therapeutic anticoagulation (AC) had less TE; AC vs no AC, 9.1% vs 90.9%, p=0.0003. Only 1 pt on Enoxaparin prophylaxis developed TE. Of the 20 pts on therapeutic AC, 25% were newly started due to concern for thrombosis; the rest were already receiving AC for other reasons. Mortality was higher in the TE group; HR, TE vs no TE, 2.6, 95% CI (1.2 - 5.6), p=0.009. There was no correlation of cancer type, disease stage (metastatic or not), administration of prior chemotherapy or immunotherapy, common comorbidities, patient setting (inpatient, ICU, outpatient, ED visit), LOS or ventilation status with increased incidence of TE. Conclusions: Pts with COVID-19 have high rates of TE, and this is true for our pts with cancer. A high incidence of ATE was noted. TE was associated with increased mortality.[Table: see text]

Published: June 2021

e18692 Background: Many providers expect that cancer survivors would be able to discontinue opioids soon after treatment, although this has not been well studied. The time cancer survivors that received curative intent radiation (CIR) remain on opioids and associated factors were examined. Methods: Electronic medical record data of cancer survivors between January 1, 2008 and December 31, 2018 and Kaplan Meier survival models were used to estimate time to discontinuation (TTD) of opioids. Cox proportional hazards models were employed to identify factors associated with TTD. Results: Median TTD was 16.8 months (95% CI: 13.1-19.1 months) following CIR and shorter for patients without opioid exposure prior to therapy (new persistent opioid use [NPOU]; 13.0 months, 95% CI: 10.0-17.3 months) compared to patients with opioid exposure prior to therapy (chronic opioid use [COU]; 21.4 months, 95% CI: 17.5-28.8 months) (p-value = 0.0004). NPOU (HR: 1.35, 95% CI: 1.07-1.71) compared to COU and head and neck (HR: 1.60, 95% CI: 1.01-2.53) in comparison to breast cancer were associated with shorter TTD. Surgery (HR: 0.68, 95% CI: 0.50-0.91), death (HR: 0.55, 95% CI: 0.34-0.91), alcohol use (HR: 0.63, 95% CI: 0.42-0.95) and nicotine use (HR: 0.78, 95% CI: 0.62-0.98) were associated with longer TTD. Conclusions: Cancer survivors receive opioids for almost 1.5 years after CIR. Patients receiving surgery and using alcohol or nicotine are at higher risk. Patients with NPOU or head and neck cancers have shorter TTD. Evidence-based guidelines for opioid use in cancer survivors are warranted due to opioid use following CIR.

e18693 Background: Among patients (pts) with endometrial cancer (EC), response rates for platinum-based regimens in the first-line (1L) setting range from 40% to 62% in clinical trials. This study describes patient characteristics, treatment patterns, time to next treatment (TTNT), and overall survival (OS) among pts with advanced/recurrent EC treated with a platinum-based regimen in a real-world setting in the US. Methods: This retrospective study used Optum Clinformatics Extended Data Mart de-identified databases from January 1, 2007, to December 31, 2019. Adult pts with advanced/recurrent EC who initiated a 1L platinum-based regimen and subsequently initiated second-line (2L) antineoplastic therapy were identified. Prior to initiation of 1L, a 12-month washout period of continuous enrollment without use of antineoplastic agents (except hormonal agents) was imposed. Kaplan-Meier (KM) rates were used to report TTNT and OS from 2L, third line (3L), and fourth line (4L), separately. Results: A total of 1878 pts with advanced/recurrent EC initiated 2L therapy following a platinum-based regimen in 1L. Among them, 739 (39.4%) pts initiated 3L and 330 (17.6%) initiated 4L or later (4L+) therapy. Median pt age was 68.0 years. More pts received platinum-based regimens (56.4%) in 2L than other options (Table). Few pts (3.3%) received immunotherapy. Among pts receiving 3L, a similar percentage of pts were treated with platinum-based (33.2%) and other chemotherapy regimens (33.8%); few pts received immunotherapy (3.0%). Among pts receiving 4L+, the most frequent treatment option was other chemotherapy (46.1%). Median TTNT was 17.7, 10.6, and 8.4 months for 2L, 3L, and 4L pts, respectively. KM rates of OS following initiation of 2L therapy at 1, 2, 3, and 4 years were 68.4%, 49.6%, 41.3%, and 33.6%, respectively, with a median OS of 23.5 months. Conclusions: Among pts with advanced/recurrent EC treated with platinum-based therapy in 1L, platinum-based regimens remain prevalent treatment choices in later lines of therapy. In this study, immunotherapy was used infrequently in 2L, 3L, and 4L+. The median TTNT decreased in later lines of therapy. This study highlights a critical need for novel, more effective treatment options in later lines of therapy to optimize outcomes among pts with advanced/recurrent EC.[Table: see text]
