Two-Pronged Nudge Strategy Significantly Increases Serious Illness Conversations in Cancer Care
核心洞察
A randomized controlled trial found that combining clinician email reminders with patient mailed letters increased serious illness conversations by 79% within 60 days.
The combined nudge arm achieved a 32.5% conversation rate using natural language processing compared to 22.6% in the control arm (P = .01).
Single-nudge interventions—clinician-only or patient-only—showed modest increases but did not reach statistical significance.
A randomized controlled trial conducted at Dana-Farber Cancer Institute has demonstrated that small, precisely timed reminders to both clinicians and patients can significantly increase the frequency of serious illness conversations in oncology care. The findings, published in the June 2026 issue of JNCCN—Journal of the National Comprehensive Cancer Network, show that a combined two-pronged nudge approach led to meaningfully higher rates of documented conversations about patients' goals and preferences for their cancer treatment.
"Past research has shown these conversations improve patient anxiety and quality of life and help them get care that matches their goals, especially near the end of life," said lead researcher Christopher R. Manz, MD, MSHP, of Dana-Farber Cancer Institute. "Having the conversation with a provider they trust, and documenting it somewhere accessible, is what allows the rest of the team to honor the patients' wishes, particularly if the patient is ill and unable to advocate for themself."
Study Design and Methodology
The four-arm randomized controlled trial enrolled 1,051 adult patients with cancer across five disease-based oncology clinics at two academic cancer center sites between December 2022 and July 2024. All participants had pathways data indicating they were starting treatment associated with a poor prognosis and did not have serious illness conversations documented within the preceding six months in the Advance Care Planning module of their electronic health record.
Patients were randomized into four arms: a patient nudge consisting of a mailed letter and questionnaire encouraging a serious illness conversation (n = 273); a clinician nudge comprising an email reminder prior to a clinic visit (n = 240); both nudges combined (n = 277); and a control arm receiving no nudges (n = 261). The researchers deliberately limited nudges to only patients starting treatments associated with poor prognosis and capped reminders at three visits.
The primary study outcome was the proportion of patients who had serious illness conversations within 60 days of randomization. A prespecified alternate outcome measure used natural language processing to identify serious illness conversations documented in the free text of clinician notes.
Key Findings
The rates of serious illness conversations occurring within 60 days, as documented in the Advance Care Planning module, were 10.7% for the control arm, 16.7% for the clinician nudge arm, 10.6% for the patient nudge arm, and 17.3% for the combined nudge arm. When natural language processing was applied to capture conversations in free-text clinician notes, the rates rose to 22.6%, 28.8%, 22.3%, and 32.5%, respectively.
Patients in the combined nudge arm had significantly higher rates of serious illness conversations compared to the control arm, both within the Advance Care Planning module (P = .045) and in free-text clinician notes identified by natural language processing (P = .01). The combined nudge group demonstrated 79% higher odds of having a serious illness conversation documented within 60 days compared to the no-nudge group. Notably, neither the clinician-only nudge nor the patient-only nudge achieved statistically significant improvements over the control group.
Precision Over Volume
"The key is precision. Nudging clinicians at the right time for the right patient rather than blasting reminders for every patient is how we turn this into a helpful quality improvement initiative rather than a burdensome email," said co-lead author Cody E. Cotner, MD, of Harvard Medical School. "Burnout is real and alert fatigue undermines the goal of these nudges: when they feel like noise, they get ignored."
Dr. Cotner further emphasized the synergistic effect of preparing both parties: "When a patient is prepared to have these conversations through initial outreach and walks into the office already thinking about what matters most to them, the clinician has a more receptive partner across the desk, and the conversation is easier to start and goes deeper."
Clinical Implications
Elise Carey, MD, a palliative care specialist at Mayo Clinic Comprehensive Cancer Center (搜索) and a member of the NCCN Clinical Practice Guidelines in Oncology Panel for Palliative Care, who was not involved with the research, commented on the study's significance. "What is especially striking is that the benefit was driven largely by the clinician nudge, suggesting that small, well-timed supports can help clinicians make space for these essential conversations even in a busy clinical practice," she noted. "Overall, this study offers a realistic, scalable step toward bringing serious illness conversations into oncology care earlier and more reliably."
Dr. Carey added that the study "offers a practical dose of hope for patients with advanced cancer and the clinicians caring for them," highlighting that "a relatively simple approach—identifying high-risk patients through existing oncology treatment pathways and sending simple reminders to both patients and clinicians—can meaningfully increase serious illness communication in routine cancer care."
