Participating surgeons noted that the reminder system added minimal friction to their workflow, as it did not require additional clicks or actions on the day of the patient visit, reported lead author Neil Carleton, PhD, of UPMC Hillman Cancer Center, Pittsburgh, and colleagues in JAMA Surgery (JAMA Surg. 2024 Jul 17. doi: 10.1001/jamasurg.2024.2407).
This effort to reduce the rate of SLNB stems from the Choosing Wisely campaign, which recommends against axillary staging in women 70 years and older with early-stage, clinically node-negative (cN0), hormone receptor–positive (HR+) breast cancer, the investigators said.
“These recommendations were developed because axillary staging did not impact survival, and rates of SLN positivity were low because of the tumor’s biological phenotype,” they wrote. “Even in older patients with tumors that exhibit concerning clinicopathologic features, limited nodal involvement does not often alter receipt of chemotherapy independently from genomic testing. Despite these recommendations, most women still receive axillary surgery.”
How Did the Nudge System Aim to Reduce the Rate of SLNB?
The nudge intervention involved adding a new column to the Epic schedule view, which flagged eligible patients during their first outpatient surgical consultation. The flag appeared as a caution sign or red clipboard icon. When surgeons hovered over the icon, a text box appeared, reminding them to consider omitting SLNB after a detailed review of core biopsy pathology and ultrasonographic imaging.
The intervention was evaluated at eight outpatient clinics within an integrated healthcare system that included seven breast surgical oncologists.
The study began with a 12-month preintervention period to serve as a control, during which time SLNB rate was determined via 194 patients in the target demographic. SLNB rate was again collected during the 12-month intervention period, which involved 193 patients meeting enrollment criteria. Between these periods, the investigators conducted a brief session lasting less than 30 minutes to introduce the surgeons to the rationale and design of the nudge column.
How Effective Was the Nudge System?
The intervention reduced the SLNB rate from 46.9% to 23.8%, representing a 49.3% decrease in use of SLNB. Efficacy was further supported by a significant reduction in SLNB according to an interrupted time series model (adjusted odds ratio, 0.26; 95% confidence interval, 0.07 to 0.90; P = .03). Extended follow-up showed that this effect was durable beyond the intervention period, with a 6-month mean reduction in SLNB of 15.6%.
Omission of SLNB led to higher rates of pathological node positivity during the intervention period (15.2% vs 8.8%), with all positive cases staged as pN1. Adjuvant therapy recommendations were similar between groups and driven by genomic testing, not nodal status. The intervention period also saw a decrease in referrals for lymphedema evaluation (3.6% vs. 6.2%).
How Might the Nudge System Be Implemented in Other Practices?
Although the SLNB nudge system was effective in the present study, likelihood of uptake among practices could vary widely, according to Anne M. Wallace, MD, professor of clinical surgery at UC San Diego Health and director of the Moores Comprehensive Breast Health Program.
On a fundamental level, not all centers use Epic software, which could present issues with compatibility, Dr. Wallace said in an interview. More importantly, she added, many institutions already have EHR-based alerts and reminders in place, so it is not always feasible to add a new nudge for every possible clinical scenario.
“Already there are so many little icons that we have to go through now when we close a note,” she said. “That’s why electronic medical records are becoming one of the leading stressors in medicine.”
This presents a more complex challenge, Dr. Wallace said, particularly as potentially practice-changing data are becoming available, and physicians may not have time to learn about them and integrate them into routine practice. She suggested that the present system may be most appropriate for oncologists in solo practice, or in small group practices where it is more challenging to have routine conversations about changing standards of care.
What Are the Risks of Using the Nudge System?
One of those conversations may surround the validity of the recommendation implemented in the present study.
Although the Society of Surgical Oncology recommends against SLNB in the described demographic, other experts, including Dr. Wallace, take a more nuanced view of the decision.
She noted that some patients with a chronological age of 70 may have a lower biological age, casting doubt on the legitimacy of the age threshold, and those near the threshold may wish to make the decision about staging for themselves.
Beyond these concerns, Dr. Wallace described two potential risks involved in forgoing SLNB.
First, there’s the potential for underestimating the tumor’s severity, she said, as this could mean a trip back to the operating room. A tumor initially thought to be low-grade might later be found to be high-grade, necessitating further surgery. Some patients might refuse additional surgery, leaving the more aggressive tumor untreated.
Second, the nudge system could complicate radiation treatment decisions, Dr. Wallace said. Without full nodal status, some radiation oncologists might push for additional radiation therapy, which incurs a greater treatment burden than SNLB.
What Are Some Alternatives to the Nudge System?
After discussing the strengths and weaknesses of the present EHR-based nudge system, and others like it, Dr. Wallace returned to the importance of ongoing communication among colleagues managing complex cases.
At UC San Diego Health, where oncologists meet weekly for a 2-hour breast cancer conference, “we nudge each other,” she said.
This study was supported by the Shear Family Foundation, UPMC eRecord Ambulatory Decision Support and Analytics, UPMC Hillman Cancer Center Biostatistics Facility, and National Institutes of Health. The investigators disclosed relationships with Pfizer, Amgen, the Lewin Group, and Milestone Pennsylvania, and others.
