Importance High-quality conversations between clinicians and seriously ill patients about values and goals are associated with improved outcomes but occur infrequently. Objective To examine feasibility, acceptability, and effect of a communication quality-improvement intervention (Serious Illness Care Program) on patient outcomes. Design, Setting, and Participants A cluster randomized clinical trial of the Serious Illness Care Program in an outpatient oncology setting was conducted. Patients with advanced cancer (n = 278) and oncology clinicians (n = 91) participated between September 1, 2012, and June 30, 2016. Data analysis was performed from September 1, 2016, to December 27, 2018. All analyses were conducted based on intention to treat. Interventions Tools, training, and system changes. Main Outcomes and Measures The coprimary outcomes included goal-concordant care (Life Priorities) and peacefulness (Peace, Equanimity, and Acceptance in the Cancer Experience questionnaire) at the end of life. Secondary outcomes included therapeutic alliance (Human Connection Scale), anxiety (Generalized Anxiety Disorder 7 scale), depression (Patient Health Questionnaire 9), and survival. Uptake and effectiveness of clinician training, clinician use of the conversation tool, and conversation duration were evaluated. Results Data from 91 clinicians in 41 clusters (72.9% participation; intervention, n = 48; control, n = 43; 52 [57.1%] women) and 278 patients (45.8% participation; intervention, n = 134; control, n = 144; 148 [53.2%] women) were analyzed. Forty-seven clinicians (97.9%) rated the training as effective (mean [SD] score, 4.3 [0.7] of 5.0 possible); of 39 who received a reminder, 34 (87.2%) completed at least 1 conversation (median duration, 19 minutes; range, 5-70). Peacefulness, therapeutic alliance, anxiety, and depression did not differ at baseline. The coprimary outcomes were evaluated in 64 patients; no significant differences were found between the intervention and control groups. However, the trial demonstrated significant reductions in the proportion of patients with moderate to severe anxiety (10.2% vs 5.0%;P = .05) and depression symptoms (20.8% vs 10.6%;P = .04) in the intervention group at 14 weeks after baseline. Anxiety reduction was sustained at 24 weeks (10.4% vs 4.2%;P = .02), but depression reduction was not sustained (17.8% vs 12.5%;P = .31). Survival and therapeutic alliance did not differ between groups. Conclusions and Relevance The results of this cluster randomized clinical trial were null with respect to the coprimary outcomes of goal-concordant care and peacefulness at the end of life. Methodologic challenges for the primary outcomes, including measure selection and sample size, limit the conclusions that can be drawn from the study. However, the significant reductions in anxiety and depression in the intervention group are clinically meaningful and require further study.

Introduction Symptoms of depression, anxiety and distress are common in the first years after a cancer diagnosis, but little is known about the prevalence of these symptoms at the long term. The aim of this review was to describe the prevalence of symptoms of depression, anxiety and distress in long‐term cancer survivors, five or more years after diagnosis, and to provide implications for primary care. Methods We performed a systematic literature search in the PubMed, PsycINFO and CINAHL databases. Studies were eligible when reporting on the prevalence of symptoms of depression, anxiety and/or distress in long‐term cancer survivors (≥5 years after diagnosis), treated with curative intent. Results A total of 20 studies were included. The reported prevalence of depressive symptoms (N = 18) varied from 5.4% to 49.0% (pooled prevalence: 21.0%). For anxiety (N = 7), the prevalence ranged from 3.4% to 43.0% (pooled prevalence: 21.0%). For distress (N = 4), the prevalence ranged from 4.3% to 11.6% (pooled prevalence: 7.0%). Conclusion Prevalences of symptoms of depression, anxiety and distress among long‐term survivors of cancer do not fundamentally differ from the general population. This is reassuring for primary care physicians, as they frequently act as the primary physician for long‐term survivors whose follow‐up schedules in the hospital have been completed.

Background: Conversations with seriously ill patients about their values and goals have been associated with reduced distress, a better quality of life, and goal-concordant care near the end of life. Yet, little is known about how such conversations are conducted. Objective: To characterize the content of serious illness conversations and identify opportunities for improvement. Design: Qualitative analysis of audio-recorded, serious illness conversations using an evidence-based guide and obtained through a cluster randomized controlled trial in an outpatient oncology setting. Setting/Measurements: Clinicians assigned to the intervention arm received training to use the "Serious Illness Conversation Guide" to have a serious illness conversation about values and goals with advanced cancer patients. Conversations were de-identified, transcribed verbatim, and independently coded by two researchers. Key themes were analyzed. Results: A total of 25 conversations conducted by 16 clinicians were evaluated. The median conversation duration was 14 minutes (range 4-37), with clinicians speaking half of the time. Thematic analyses demonstrated five key themes: (1) supportive dialogue between patients and clinicians; (2) patients' openness to discuss emotionally challenging topics; (3) patients' willingness to articulate preferences regarding life-sustaining treatments; (4) clinicians' difficulty in responding to emotional or ambiguous patient statements; and (5) challenges in discussing prognosis. Conclusions: Data from this exploratory study suggest that seriously ill patients are open to discussing values and goals with their clinician. Yet, clinicians may struggle when disclosing a time-based prognosis and in responding to patients' emotions. Such skills should be a focus for additional training for clinicians caring for seriously ill patients.

Background: Asian healthcare professionals hold that patients’ families play an essential role in advance care planning. Aim: To systematically synthesize evidence regarding Asian patients’ perspectives on advance care planning and their underlying motives. Design: Mixed-method systematic review and the development of a conceptual framework (PROSPERO: CRD42018099980). Data sources: EMBASE, MEDLINE, Web of Science, and Google Scholar were searched for studies published until July 27, 2020. We included studies concerning seriously-ill Asian patients’ perspectives on advance care planning or their underlying motives for engaging or not engaging in it. Results: Thirty-six articles were included; 22 were quantitative and 27 were from high-income countries. Thirty-nine to ninety percent of Asian patients were willing to engage in advance care planning. Our framework highlighted that this willingness was influenced not only by their knowledge of their disease and of advance care planning, but also by their beliefs regarding: (1) its consequences; (2) whether its concept was in accordance with their faith and their families’ or physicians’ wishes; and (3) the presence of its barriers. Essential considerations of patients’ engagement were their preferences: (1) for being actively engaged or, alternatively, for delegating autonomy to others; (2) the timing, and (3) whether or not the conversations would be documented. Conclusion: The essential first step to engaging patients in advance care planning is to educate them on it and on their diseases. Asian patients’ various beliefs about advance care planning should be accommodated, especially their preferences regarding their role in it, its timing, and its documentation.

Background: Serious illness conversations are part of advance care planning (ACP) and focus on prognosis, values, and goals in patients who are seriously ill. To be maximally effective, such conversations must be documented accurately and be easily accessible. Objectives: The two coprimary objectives of the study were to assess concordance between written documentation and recorded audiotaped conversations, and to evaluate adherence to the Serious Illness Conversation Guide questions. Methods: Data were obtained as part of a trial in patients with advanced cancer. Clinicians were trained to use a guide to conduct and document serious illness conversations. Conversations were audiotaped. Two researchers independently compared audiorecordings with the corresponding documentation in an electronic health record (EHR) template and free-text progress notes, and rated the degree of concordance and adherence. Results: We reviewed a total of 25 audiorecordings. Clinicians addressed 87% of the conversation guide elements. Prognosis was discussed least frequently, only in 55% of the patients who wanted that information. Documentation was fully concordant with the conversation 43% of the time. Concordance was best when documenting family matters and goals, and least frequently concordant when documenting prognostic communication. Most conversations (64%) were documented in the template, a minority (28%) only in progress notes and two conversations (8%) were not documented. Concordance was better when the template was used (62% vs. 28%). Conclusion: Clinicians adhered well to the conversation guide. However, key information elicited was documented and fully concordant less than half the time. Greater concordance was observed when clinicians used a prespecified template. The combined use of a guide and EHR template holds promise for ACP conversations.
