Palliative care integration in oncology: narrative review

Area of Science:

• Oncology
• Palliative Care
• Health Services Research

Background:

• Palliative care integration enhances oncology patient symptoms, quality of life, communication, and survival.
• Current integration into routine oncology practice is inconsistent, delayed, and inequitable.

Purpose of the Study:

• Critically review international guidelines for integrating palliative care into oncology.
• Identify gaps in referral timing, triggers, team composition, and resource stratification.
• Propose practical service-delivery models and implementation strategies for equitable integration.

Main Methods:

• Systematic review of meta-analyses, randomized controlled trials, and international guidelines.
• Analysis of existing evidence on palliative care integration across diverse global settings.
• Identification of barriers and disparities in palliative care delivery.

Main Results:

• Evidence supports early, concurrent palliative care by interdisciplinary oncology teams.
• Significant gaps persist in referral triggers, service standards, and performance metrics, especially for hematologic malignancies and underserved populations.
• Workforce shortages, inequitable opioid access, and financing gaps create disparities for pediatric, rural, low-income, and minority populations.

Conclusions:

• Shift focus from demonstrating benefits to ensuring equitable, timely palliative care delivery in oncology.
• Strengthen primary palliative care, establish clear referral triggers, and secure sustainable funding.
• Implement measurable quality indicators and resource-stratified adaptations to overcome implementation barriers.
