Global Survey Reveals Over 80% of Cancer Providers Lack Knowledge to Recommend Integrative Oncology Therapies
核心洞察
A global survey of 282 oncology providers found that more than 80% cite lack of knowledge as a key barrier to recommending integrative oncology (搜索) therapies such as yoga, acupuncture, and mindfulness training.
Financial obstacles including lack of insurance coverage and high out-of-pocket costs were identified by roughly 80% of respondents as preventing patient access to complementary cancer care.
European providers were more than twice as likely as North American counterparts to report knowledge gaps as a barrier (OR = 2.22, 95% CI = 1.05–4.67, P = .036).
More than 8 in 10 cancer care providers worldwide say they lack sufficient knowledge about integrative oncology (搜索) to confidently recommend these therapies to patients, according to a global survey published in Supportive Care in Cancer. The study, led by researchers at the University of California, Irvine, surveyed 282 members of the Multinational Association of Supportive Care in Cancer (搜索) (MASCC) and the Society for Integrative Oncology (搜索) (SIO), spanning more than a dozen world regions and including physicians, nurses, pharmacists, psychologists, and complementary-therapy practitioners.
"The good news here is that this isn't a mystery we can't solve. Providers want to help their patients access these therapies—they just haven't had the training, the referral pathways or the confidence to do it well. That's a fixable problem," said corresponding study author Alexandre Chan, PharmD, PhD, MPH, Professor of Clinical Pharmacy in UC Irvine's School of Pharmacy & Pharmaceutical Sciences and President of MASCC.
Knowledge Gaps Dominate the Barrier Landscape
Every single knowledge-related barrier assessed in the survey drew majority agreement from respondents. More than 80% of participants reported that a lack of provider experience and training holds back integrative oncology (搜索) in their own practices, while three-quarters said providers are simply not aware of what integrative oncology encompasses. Additionally, 85% of respondents acknowledged a personal lack of confidence in integrative oncology.
A notable geographic disparity emerged: providers in Europe were 2.2 times more likely than those in North America to cite lack of knowledge as a perceived barrier (odds ratio = 2.22; 95% confidence interval = 1.05–4.67; P = .036). The study authors noted that this regional difference warrants closer investigation.
Financial and Logistical Hurdles Compound the Problem
Financial concerns followed closely behind knowledge gaps. Roughly 80% of respondents pointed to a lack of insurance coverage and out-of-pocket costs as significant obstacles, and 88% said they believe their patients simply cannot afford complementary therapies. Because integrative oncology (搜索) research is still relatively young, insurers have limited basis for reimbursement, leaving patients to shoulder costs themselves.
Logistical barriers also received broad acknowledgment. About 80% of respondents felt that a lack of referral pathways was a barrier to recommending integrative oncology (搜索). Eight of 13 system-level barriers assessed received majority agreement, including lack of time and insufficient interdisciplinary coordination.
Notably, integrative oncology (搜索) professionals were more than three times as likely as general physicians to express concern that recommending complementary care might delay a patient's conventional treatment (OR = 3.62; 95% CI = 1.56–8.43; P = .0003). The researchers suggest this perception reflects a communication gap between specialties as much as any real clinical risk.
A Solvable Problem with Concrete Solutions
Chan and his co-authors frame the findings as identifying fixable problems rather than intractable ones. Their paper argues that continuing-education requirements, mentorship programs pairing experienced integrative practitioners with newcomers, and searchable resource libraries built into electronic health records could close much of the knowledge gap within existing health systems—without waiting for new legislation or funding streams.
Integrative oncology (搜索) blends standard cancer treatment with evidence-based complementary approaches—including nutrition counseling, yoga, acupuncture, aromatherapy, and mind-body practices—aimed at easing symptoms and improving quality of life during and after treatment. A growing body of evidence supports its use for pain, fatigue, anxiety, and other treatment side effects. Yet prior research has shown that only 15% of patients recalled a provider even raising the subject.
Study Limitations
The authors acknowledge that the findings represent perspectives from providers already engaged enough in the field to belong to MASCC or SIO, and response rates were modest. As such, the results may not apply to all oncology professionals, and further research is needed to understand global roadblocks to integrative oncology (搜索) use. Nonetheless, this is the first study to quantify these barriers at an international scale, providing hospitals, medical schools, and professional societies with a concrete list of actionable fixes.
