PURPOSE To evaluate the clinical patterns of utilization of OncotypeDX Recurrence Score (RS) in early-stage, hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer (BC) at an academic center with previously established internal reflex testing guidelines. METHODS RS testing in accordance with preexisting reflex criteria and predictors of utilization outside of reflex criteria were retrospectively analyzed for the years 2019- 2021 in a quality improvement evaluation. Patients were grouped according to OncotypeDX testing within (cohort A) or outside (cohort B) of predefined criteria which included a cap at age older than 65 years. RESULTS Of 1,687 patients whose tumors had RS testing, 1,087 were in cohort A and 600 in cohort B. In cohort B, nearly half of patients were older than 65 years (n = 279; IQR, 67-72 years). For patients older than 65 years, those with RS testing were younger (median age: 69 v 73 years), with higher grade cancers (G2-3: 84.9% v 54.7%) and were more likely to be treated with chemotherapy (15.4% v 4.1%). Issues for implementation of RS testing in older patients were identified, including potential structural barriers related to the current policy on the reimbursements of genomic tests. CONCLUSION Internal guidelines may facilitate standardized utilization of the RS in early-BC. Our data suggest that clinicians preferred broader utilization of RS across the age spectrum, with therapeutically important consequences. Modifying the current policy for reimbursement of RS testing and in internal reflexive testing criteria for those older than 65 years is warranted. [ABSTRACT FROM AUTHOR]

Clinical pathways have the potential to improve complex clinical decision-making in cancer care. The authors implemented pathways with customized content to assist oncologists to select treatments, aiming for an on-pathway rate of 70%-85%. Treatment decisions were captured as on or off pathway, and metrics were shared monthly with users. Oncologists were categorized into quintiles based on on-pathway performance during the first 90 days of use. On-pathway rates were then calculated for days 91-360 (N = 121). Median on-pathway quintile rates varied from 50% to 100% in the initial 90-day period. During follow-up, median on-pathway rates shifted into the prespecified goal range for all groups. Clinical pathways resulted in greater uniformity in medical oncology practice. Monthly feedback about usage, familiarity with the electronic platform, and regular content updates are some factors that may influence on-pathway rates. Clinical pathways hold promise to manage unwarranted variation in cancer care. [ABSTRACT FROM AUTHOR]

Service systems are often stochastic and preplanned by appointments, yet implementations of their appointment systems are prevalently deterministic. At the planning stage of healthcare services, for example, customer punctuality and service durations are often assumed equal their means—and this gap, between planned and reality, motivated our research. Specifically, we consider appointment scheduling and sequencing under a time-varying number of servers, in a data-rich environment where service durations and punctuality are uncertain. Our data-driven approach, based on infinite-server queues, yields tractable and scalable solutions that accommodate hundreds of jobs and servers. We successfully test our approach against near-optimal algorithms (which exist for merely single-servers). This entails the development of a data-driven robust optimization approach with novel uncertainty sets. To test for practical performance, we leverage a unique data set from a cancer center that combines real-time locations, electronic health records, and appointments log. Focusing on one of the center's infusion units (roughly 90 daily appointments, 25+ infusion chairs), we reduce cost (waiting plus overtime) on the order of 15%–40% consistently, under a wide range of experimental setups. This paper was accepted by Assaf Zeevi, stochastic models and simulation. [ABSTRACT FROM AUTHOR]

Purpose: A few previous studies report a direct relationship between older age and chemotherapy‐induced neuropathy. This study further evaluated this adverse event's age‐based risk. Methods: CALGB 40101 investigated adjuvant paclitaxel (80 mg/m2 once per week or 175 mg/m2 every 2 weeks) in patients with breast cancer and served as a platform for the current study that investigated age‐based differences in neuropathy. Grade 2 or worse neuropathy, as per Common Terminology Criteria for Adverse Events version 4, was the primary endpoint; patients were assessed at baseline, every 6 months for 2 years, and then annually for 15 years. Results: Among these 1,881 patients, 230 were 65 years of age or older, 556 were 55–64 years, and 1,095 were younger than 55; 1,226 neuropathy events (commonly grade 1 or 2) were reported in 65% of the cohort. The number of grade 2 or worse events was 63 (27%), 155 (28%), and 266 (24%) within respective age groups (p =.14). In univariate analysis, only motor neuropathy had a higher age‐based incidence: 19 (8%), 43 (8%), and 60 (5%), respectively (p =.04); in multivariate analyses, this association was no longer statistically significant. Other endpoints, such as time to onset of neuropathy (time from trial enrollment to neuropathy development) and time to improvement (time from maximal grade sensory neuropathy to a one‐category improvement), showed no statistically significant age‐based differences. In contrast, obesity was associated with neuropathy, and every 2‐week paclitaxel was associated with trends toward neuropathy. Conclusion: Although paclitaxel‐induced neuropathy is common, older age is not an independent risk factor. Clinical trial identification number. NCT00041119 (CALGB 40101). Implications for Practice: Age alone is not an independent risk factor for paclitaxel‐induced neuropathy. Mixed results have been reported regarding whether older cancer patients are at a greater risk for chemotherapy‐induced neuropathy. This article further evaluates the age‐based risk of this adverse event. [ABSTRACT FROM AUTHOR]

Purpose Delays to adjuvant chemotherapy initiation in breast cancer may adversely affect clinical outcomes and patient satisfaction. We previously identified an association between genomic testing (Oncotype DX) and delayed chemotherapy initiation. We sought to reduce the interval between surgery and adjuvant chemotherapy initiation by developing standardized criteria and workflows for Oncotype DX testing. Methods Criteria for surgeon-initiated reflex Oncotype DX testing, workflows for communication between surgeons and medical oncologists and a streamlined process for receiving and processing Oncotype DX requests in pathology were established by multidisciplinary consensus. Criteria for surgeon-initiated testing included patients ⩽ 65 years old with T1cN0 (grade 2 or 3), T2N0 (grade 1 or 2), or T1/T2N1 (grade 1 or 2) breast cancer on final surgical pathology. Medical oncologists could elect to initiate Oncotype testing for cases falling outside the criteria.Wethen examined 720 consecutive patients with breast cancer who underwent Oncotype DX testing postoperatively between January 1, 2014 and November 28, 2016 and measured intervals between date of surgery, Oncotype DX order date, result received date and chemotherapy initiation date (if applicable) before and after intervention implementation. Results The introduction of standardized criteria and workflows reduced time between surgery and OncotypeDXordering and time from surgery to receipt of result, by 7.3 days (P,.001) and 6.3 days (P<.001), respectively. The mean number of days between surgery and initiation of chemotherapy was also reduced by 6.4 days (P = .004). Conclusion Developing consensus on Oncotype DX testing criteria and implementing streamlined workflows has led to clinically significant reductions in wait times to chemotherapy decision making and initiation.

Purpose Mastectomy with immediate reconstruction (MIR) requires coordination between breast and reconstructive surgical teams, leading to increased preoperative delays that may adversely impact patient outcomes and satisfaction. Our cancer center established a target of 28 daysfrom initial consultation with the breast surgeon to MI R.We sought to determine if a centralized breast/reconstructive surgical coordinator (BRC) could reduce care delays. Methods A 60-day pilot to evaluate the impact of a BRC on timeliness of care was initiated at our cancer center. All reconstructive surgery candidates were referred to the BRC, who had access to surgical clinic and operating room schedules. The BRC worked with both surgical services to identify the earliest surgery dates and facilitated operative bookings. The median time to MIR and the proportion of MIR cases that met the time-to-treatment goal was determined. These results were compared with a baseline cohort of patients undergoing MIR during the same time period (January to March) in 2013 and 2014. Results A total of 99 patients were referred to the BRC (62% cancer, 21% neoadjuvant, 17% prophylactic) during the pilot period. Focusing exclusively on patients with a cancer diagnosis, an 18.5% increase in the percentage of cases meeting the target (P = .04) and a 7-day reduction to MIR (P = .02) were observed. Conclusion A significant reduction in time to MIR was achieved through the implementation of the BRC. Further research is warranted to validate these findings and assess the impact the BRC has on operational efficiency and workflows. [ABSTRACT FROM AUTHOR]

Background: National guidelines endorse time-dependent quality metrics for breast cancer care. We examined factors associated with delays in chemotherapy initiation at an NCI-Designated Comprehensive Cancer Center., Patients and Methods: We identified 523 patients who received postoperative adjuvant chemotherapy between January 2011 and December 2013 at our center. We defined 28 days from last definitive surgery (LDS) to chemotherapy as the target time frame, and an unacceptable delay in chemotherapy initiation (UCD) as greater than 42 days from LDS. Multivariate regression models were used to identify factors associated with UCD and the impact of Oncotype DX testing in patients with hormone receptor (HR)-positive breast cancer., Results: Median days between LDS and chemotherapy initiation was 34 (interquartile range, 15), with 30% of patients starting within 28 days of LDS and 26.9% having UCD. Tumor characteristics such as subtype and stage affected UCD; patients with HR-positive or HER2-positive tumors were more likely to be delayed compared with those with triple-negative breast cancer. Patients with stage I disease, those undergoing mastectomy with or without immediate reconstruction, and those whose pathology sign-out was greater than 10 days postoperatively were more likely to be delayed. A higher proportion of UCD was found in HR-positive patients (31%) for whom Oncotype DX testing was ordered compared with those in whom it was not ordered (20%)., Conclusions: This study provides insight into subpopulations that may be at risk to experience delays in chemotherapy initiation, directing interventions to improve the timeliness of care., (Copyright © 2016 by the National Comprehensive Cancer Network.)

This article describes how trust among team members and in the technology supporting them was eroded during implementation of an electronic health record (EHR) in an adult outpatient oncology practice at a comprehensive cancer center. Delays in care of a 38-year-old woman with high-risk breast cancer occurred because of ineffective team communication and are illustrated in a case study. The case explores how the patient's trust and mutual trust between team members were disrupted because of inaccurate assumptions about the functionality of the EHR's communication tool, resultant miscommunications between team members and the patient, and the eventual recognition that care was not being effectively coordinated, as it had been previously. Despite a well-established, team-based culture and significant preparation for the EHR implementation, the challenges that occurred point to underlying human and system failures from which other organizations going through a similar process may learn. Through an analysis and evaluation of events that transpired before and during the EHR rollout, suggested interventions for preventing this experience are offered, which include: a thorough crosswalk between old and new communication mechanisms before implementation; understanding and mitigation of gaps in the communication tool's functionality; more robust training for staff, clinicians, and patients; greater consideration given to the pace of change expected of individuals; and development of models of collaboration between EHR users and vendors in developing products that support high-quality, team-based care in the oncology setting. These interventions are transferable to any organizational or system change that threatens mutual trust and effective communication.
