Top Ten Tips Palliative Care Clinicians Should Know About Psychedelic-Assisted Therapy in the Context of Serious Illness.

Journal of palliative medicine August 1, 2022 William E Rosa, Zachary Sager, Megan Miller et al. 49 citations

Psychedelic-assisted therapy (PAT) is a promising treatment for conditions like treatment-resistant depression, substance use disorder, and PTSD. In palliative care, a single PAT session can produce lasting reductions in anxiety, depression, and demoralization—symptoms that harm quality of life for seriously ill and end-of-life patients. Although interest in psychedelics has revived, few resources exist for applying PAT in hospice and palliative care. This article provides 10 evidence-informed tips for palliative care clinicians, developed with international experts, to help familiarize teams with PAT, address legal and logistical barriers, discuss therapeutic competencies, and highlight approaches to maximize safety and benefits for patients and caregivers.

Palliative Nursing and Sacred Medicine: A Holistic Stance on Entheogens, Healing, and Spiritual Care.

Journal of holistic nursing : official journal of the American Holistic Nurses' Association March 1, 2019 William E Rosa, Stephanie Hope, Marianne Matzo 27 citations

Entheogens—medicines that induce experiences of the sacred—show promise in helping patients with advanced serious illness find meaning, reduce fear, and increase joy and acceptance. Clinical trials have yielded impressive preliminary findings on their healing potential, yet nursing literature has not engaged with these advancements. The article introduces scholarly dialogue on integrating entheogens into spiritual and holistic nursing care, provides a brief history of their global use, and includes a case study. Evidence-based knowledge on this sensitive topic is needed to foster understanding, advance scientific knowledge, and create healing environments for patients, nurses, and researchers.

Applying Key Lessons from the Hospice and Palliative Care Movement to Inform Psychedelic-Assisted Therapy.

Psychedelic medicine (New Rochelle, N.Y.) September 1, 2023 Megan Miller, William E Rosa, Alden Doerner Rinaldi et al. 9 citations

Psychedelic-assisted therapy (PAT) and hospice/palliative care share deep synergies that could help integrate PAT into mainstream health systems. Hospice and palliative care, though now evidence-based standards, began as grassroots movements. Their holistic, interdisciplinary, relationship-centered, and spiritually attuned models offer practical lessons for scaling human-centered PAT. Key aspects include interdisciplinary care, holistic views of health, bearing witness to suffering, customized care, decentralized models, generalist/specialist competencies, fostering spirituality, and growth from community organizations to mature systems. Conversely, PAT's radical emphasis on meaning-making and relationship may also innovate hospice and palliative care.

Cosmology of belonging: The role of community in the therapeutic use of psychedelics.

Palliative & supportive care January 21, 2025 Caroline Dorsen, Lola Noero, Michelle Knapp et al. 5 citations

Fifteen facilitators of naturalistic psychedelic groups in the United States described community as essential to every aspect of psychedelic work: from motivation to use psychedelics, through the dosing experience, to integrating lessons into daily life. Thematic analysis identified two overarching themes: the arc of healing through community (with subthemes of intention, the group journey experience, and integration) and naturally occurring psychedelic communities as group therapy (with subthemes of belonging, authenticity, corrective experience, trust, and touch). The findings suggest that existing knowledge about therapeutic group processes may help structure and optimize group psychedelic work. More research is needed on group size, composition, substance selection, facilitator training, and community integration. Psychedelic groups may provide benefits that individual work does not.

A Rapid Review of Psychedelic-Assisted Therapy in the Context of Palliative Care.

Journal of hospice and palliative nursing : JHPN : the official journal of the Hospice and Palliative Nurses Association April 1, 2025 Megan Miller, Molly Meyers, Annona Martin et al. 3 citations

A rapid review of 34 articles from 2021 to 2024 finds that psychedelic-assisted therapy (PAT) is safe and shows initial efficacy for improving psycho-spiritual-existential outcomes in carefully screened patients with serious illness, predominantly cancer. Psilocybin was the most studied compound. Protocols commonly included participant screening, preparation, dosing, and integration. The review highlights current efforts and challenges in integrating PAT into palliative care systems. More research is needed with diverse samples, provider training, care delivery models, and policy solutions. Many patients lack basic psychosocial-spiritual-existential care, so careful integration is essential. The psychedelic substances discussed are not FDA approved.

Meaning-Centered Psychotherapy for Psilocybin-Assisted Therapy Among Patients with Advanced Cancer and Depression: Rationale and Preliminary Evaluation of MCP-PSIL.

Psychedelic medicine (New Rochelle, N.Y.) June 1, 2026 William E Rosa, Stephanie Napolitano, Natalie Mcandrew et al.

Meaning-centered psychotherapy (MCP) is a manualized, brief intervention that enhances meaning and purpose and appears to be a natural therapeutic partner for psilocybin-assisted therapy (PAT) in patients with cancer and major depressive disorder. In a phase 2 open-label trial, seven patients (ages 53-80) and six therapists (with 9-44 years of experience) participated in surveys and focus groups to adapt MCP for psilocybin. Focus groups highlighted the value of psilocybin experiences, group support, and MCP both separately and together. A 5-session model called MCP-PSIL was developed. The group format was emphasized, though individual MCP may be appropriate in some cases.

A Blueprint for Implementing Ketamine-Assisted Psychotherapy in Palliative Care: Design, Process, and Treatment Patterns of a Real-World Clinical Program.

Journal of palliative medicine March 1, 2026 Robert K Horowitz, William E Rosa, Ali John Zarrabi et al.

Psychospiritual distress causes profound suffering in people with serious illness, yet treatment options are few. A palliative care-embedded ketamine-assisted psychotherapy (KAP) program called Pal-KAP was developed and delivered at an academic medical center. Between May 2023 and September 2025, 59 patients were referred for screening; 43 met eligibility criteria, and 30 elected to participate. Patients (age 19-76, mean 53) completed a median of 1.5 medicine sessions (range 1-5). Most had cancer (80%) or neurological disease (13.3%). Ketamine dose averaged 0.93 mg/kg intramuscularly, with minor adverse effects and no serious adverse events. This experience suggests that KAP can be delivered safely and ethically in palliative care.
