Description

Scientific background: The provision of complementary and integrative medicine therapies within supportive and palliative oncology care (herewith, Integrative Oncology, IO) is increasingly taking place in leading oncology centers across the globe. The Society for Integrative Oncology (SIO) and the American Society of Clinical Oncology (ASCO) have co-published clinical practice guidelines on the effective and safe use of these modalities for patients with cancer. The proposed study will explore the provision of IO care to patients with cancer during hospitalization, with the goal of addressing emotional distress, pain, fatigue, gastro-intestinal symptoms, and other quality of life (QoL)-related concerns.

Study objectives and purpose: The primary study objective is to improve patients' QoL-related concerns while hospitalized for a variety of cancer-related indications. This, in a clinical context in which in-patient IO interventions are provided together with palliative care, with the two teams coordinating their work. Secondary objective is to identify barriers and enablers to the continuity of IO care, following hospitalization, for patients with cancer, from the in-patient hospital to the out-patient community care setting.

Methods: Study design and setting: The proposed study will take place within a prospective randomized controlled methodology, beginning with a patient-preference stage, in which patients are asked to choose whether they are interested in undergoing IO treatments or palliative nursing counseling.

Study population: Patients of either gender, diagnosed with cancer, age ≥ 18 years and hospitalized in one of the five surgical/internal departments will be eligible for study inclusion. Participating patients will be referred to the study team by a medical healthcare provider in their respective departments, providing a list of clinical indications for the referral.

Allocation to study arms and groups:

Participants will be allocated to one of the two primary study arms, based on their preference for undergoing IO treatments:

• Integrative oncology (IO) arm (Groups A and B): Patients choosing to undergo IO treatments, in addition to standard palliative care
• Palliative nursing counseling (Group C): Patients choosing to undergo a palliative nursing consultation only.

Patients choosing to receive IO care will then be randomly and openly assigned to one of the intervention groups, using the "Research Randomizer" online tool (https://www.randomizer.org/), to one of the following study groups:

• Single-modality IO, receiving acupressure/relaxation only (Group A)
• Multi-modality IO receiving acupressure/relaxation with acupuncture (Group B) IO treatments and palliative nursing consultation: Patients in the intervention arm of the study (groups A and B) will be interviewed and assessed by the IO practitioner, while a palliative nurse specialist will interview those choosing the palliative nursing consultation (Group C). In all study groups, the interviews will address QoL-related concerns, identifying the patient's leading concern (e.g., pain, anxiety). Following the QOL assessment in both groups, an integrative or palliative intervention with the goal of alleviating the patient's leading QoL-related concerns over the next 24-hour period.

Patients in the IO intervention arm of the study will undergo acupressure/relaxation treatments only (Single Modality, Group A), or with the addition of acupuncture (Multi-Modality, Group B). The acupressure/acupuncture points will be designated according to a protocol for each of the four leading concerns (pain, fatigue, emotional, and gastrointestinal), based on evidence-based research. The palliative nursing intervention (Group C) will entail a personalized bio-psycho-social-oriented discussion, highlighting the patient's and their informal caregiver's unmet needs and QoL-related concerns.
