Tyack Health: The communication gap that makes CAM dangerous — and how to close it

At Tyack Health, supporting safe, informed, and integrated healthcare is at the heart of everything we do. Most patients who use complementary and alternative medicine (CAM) do so quietly. They take their St. John's Wort, attend their acupuncture sessions, or follow a naturopath's supplement protocol and never mention any of it to their prescribing physician. This silence isn't unusual; it's actually the statistical norm, and it's something we feel strongly about changing.

A landmark national survey found that 72 percent of CAM therapy users did not inform their medical doctors that they used CAM (Eisenberg et al., 1993). Decades later, the pattern persists: in a comprehensive national study, 1,023 of 3,118 (33.3%) participants with a history of cancer reported CAM use in the past year, and 288 (29.3%) of those did not disclose it to their physician.

The consequences go well beyond paperwork. When patients don't disclose CAM use, real safety issues follow — drug-herb interactions being the most serious. In a Medicare population, 5.8% of participants took combinations considered to carry significant adverse interaction risk, most involving bleeding risk from ginkgo, garlic, or ginseng used alongside aspirin, warfarin, ticlopidine, or pentoxifylline.

This guide is here to help close that gap, for patients who want to use CAM thoughtfully and for clinicians who want to support safe, integrated care. It translates the evidence into a clear, step-by-step protocol grounded in shared decision-making. For the foundational science underpinning which CAM therapies have demonstrated efficacy, see our guide on What Is Evidence-Based CAM? Definitions, Domains, and the Science Behind Complementary and Alternative Medicine.

Why patients don't tell their doctors — and why that needs to change

Understanding the communication gap is the first step toward resolving it, and it starts with empathy.

Among patients who reported reasons for nondisclosure, the most common were: "It wasn't important for the doctor to know" (61 percent), "The doctor never asked" (60 percent), "It was none of the doctor's business" (31 percent), and "The doctor would not understand" (20 percent).

A survey coordinated by the NCCAM and the AARP found that although more than two thirds of patients older than 50 used some form of CAM treatment, fewer than one third discussed it with their physician. And those who did? They were the ones who brought it up themselves. Clinicians are largely waiting for patients to raise a topic that patients believe clinicians don't want to hear.

CAM disclosure is particularly low among racial and ethnic minorities. Having a regular doctor and a quality patient-provider relationship helps close that gap — a finding with real implications for health equity in our communities.

Closing this gap requires action from both sides. When clinicians initiate the conversation about CAM, or at minimum signal that they're genuinely open to it, communication improves. Patients notice when the door is open.

The six-step integration protocol

The following framework is designed for patients preparing to introduce CAM into their care, and for clinicians structuring those conversations. It draws on shared decision-making principles validated in integrative medicine research. At Tyack Health, this kind of structured, evidence-informed approach underpins how we think about integrative care, because good intentions need a solid framework to become genuinely safe practice.

Step 1: Define your health goals and the role of CAM

Before evaluating any specific therapy, both patient and clinician should establish what the patient is actually trying to achieve. CAM integrates most safely when it serves a clearly defined, bounded purpose — symptom management, quality of life, stress reduction — rather than functioning as an undisclosed replacement for evidence-based care.

Some useful clarifying questions to work through together:

• Is the goal to complement an existing treatment plan, or to replace a conventional therapy?
• Is the condition acute, where delays in conventional care carry serious risk, or chronic, where adjunctive approaches may offer meaningful benefit?
• What does the patient value most: symptom relief, reduced medication burden, a greater sense of agency, cultural alignment?

Shared decision-making has real potential to introduce patients to CAM modalities through an integrative approach, building a partnership that puts patient-centred outcomes first. This matters especially for patients with chronic conditions who are trying to improve their overall quality of life.

Step 2: Evaluate the evidence for the specific therapy

Not all CAM modalities carry equal evidence, and it's worth approaching each one with clear eyes. Before incorporating any therapy, consult the evidence hierarchy — from systematic reviews and randomised controlled trials down to case reports and expert consensus. The National Center for Complementary and Integrative Health (NCCIH) maintains a searchable database of evidence summaries by condition and modality, and the Cochrane CAM collection provides independent systematic reviews.

Key questions worth working through:

• Is there a Cochrane review or NCCIH-funded trial addressing this therapy for this specific condition?
• Does the evidence come from independent sources, or predominantly from industry-funded trials?
• Has the therapy been evaluated in populations similar to the patient, considering age, comorbidities, and concurrent medications?

For a detailed comparative look at evidence tiers across acupuncture, herbal medicine, chiropractic, mindfulness-based stress reduction, and other major modalities, see our guide on CAM Therapies by Strength of Evidence.

Step 3: Screen for contraindications and drug-herb interactions

This is the most clinically important step — and, unfortunately, the one most frequently skipped. A 2024 study found a 15.6% rate of potential drug interactions among older adults using CAM and/or OTC medications.

The highest-risk interactions involve herbal supplements and pharmaceutical agents that share metabolic pathways or pharmacodynamic mechanisms. Some clinically important examples:

Approximately 70% of people who use herbal medications don't mention it to their prescribers or pharmacists. Unless practitioners actively ask — using language that captures supplements, herbal products, and OTC preparations, not just "medications" — drug-herb interactions will keep slipping through undetected.

A practical screening approach for clinicians:

1. Ask explicitly about supplements, herbal products, and OTC preparations, not just prescription medications
2. Use a structured tool such as the NCCIH's drug interaction checker at MedlinePlus or the Natural Medicines Database
3. Document all CAM use in the patient's electronic health record and run a vigilant interaction screen

Step 4: Evaluate practitioner credentials

There is no standardised national credentialing system for complementary health practitioners in Australia. State and territory governments decide what credentials practitioners must hold, and the variation across modalities and jurisdictions is significant. Patients often have to navigate this on their own, which is why we want to make it as straightforward as possible.

Key credentialing benchmarks by modality:

Chiropractors are registered in all Australian states and territories. Registration requires four years of chiropractic education and is managed by AHPRA (Australian Health Practitioner Regulation Agency).

For acupuncture, AHPRA and state-based registration boards oversee practitioner standards in most jurisdictions.

For naturopathy, registration varies by state and territory. Some states have specific legislation, whilst others do not currently regulate naturopaths under AHPRA. Naturopaths typically complete four years of naturopathic medical college training.

Some healthcare organisations are developing their own internal standards, which may include proof of training, licensure or certification, background checks, continuing education hours, professional indemnity insurance, and relevant clinical experience.

Questions patients should feel comfortable asking any CAM practitioner before beginning treatment:

• What is your formal training, and from which accredited institution?
• Are you registered or certified in this state or territory, and by which body?
• Have you treated patients with my specific condition? What were the outcomes?
• Will you communicate with my primary care physician or specialist?

Step 5: Disclose CAM use to all members of the care team

Disclosure isn't a single conversation — it's an ongoing part of the care relationship, and it matters at every stage. The NCCAM recommends practical strategies: adding a CAM question to medical history forms; asking patients for a complete list of everything they take or do, including prescription medications, over-the-counter products, herbal therapies, and other CAM practices; or having a nurse or other staff member open the conversation before the clinician enters the room.

From the patient side, disclosure should cover:

• The name and form of every supplement or herbal product, including brand name, dose, and frequency
• All practitioner-delivered CAM, such as acupuncture, chiropractic, and massage
• Any dietary protocols recommended by a CAM provider
• Any CAM therapies being used instead of a previously prescribed conventional treatment

The conversation needs to happen in a nonjudgmental way that earns the patient's trust, respects their cultural beliefs about CAM, and results in documented use in the patient's medication records so that a proper interaction screen can be run.

When patients feel genuinely safe disclosing their CAM use, providers gain a clearer picture of their patients' values and preferences — and that makes it possible to build an integrative treatment plan that draws on the best of both conventional and complementary medicine.

Step 6: Monitor outcomes using validated tools

Integration without monitoring isn't safe integration; it's just hope. Outcome tracking should be prospective, structured, and use validated instruments wherever possible. At Tyack Health, consistent evidence-based monitoring is what turns good intentions into genuinely safe integrative care.

A practical outcome monitoring framework:

For symptom tracking, use validated patient-reported outcome measures relevant to the condition — the Brief Pain Inventory for pain, PHQ-9 for depression, PROMIS scales for general health.

For laboratory monitoring, any herbal supplement with known metabolic interactions (St. John's Wort with anticoagulants, for example) warrants follow-up labs at appropriate intervals.

For functional outcomes, assess changes in activity level, sleep quality, and medication requirements every 4 to 6 weeks.

For adverse event tracking, encourage patients to report new symptoms promptly, and report serious events to the TGA's Adverse Event Reporting program.

As with any therapeutic decision, patients should be included in the process and given clear, evidence-based information to weigh the risks and benefits for their individual situation.

The clinician's role in shared decision-making

The growing use of CAM in Australia has created a genuine need for care systems that encourage open communication between patients and providers. Shared decision-making is the connecting force between holistic treatment and improved health outcomes, and it's a model we fully support.

The three-talk model, endorsed by NICE and the American Academy of Family Physicians, offers a practical clinical structure. Its three stages — team talk, option talk, and decision talk — give clinicians a way to structure the shared decision-making process during the visit.

Applied to CAM integration, this works as follows:

Team talk means creating a warm, non-judgmental space where the patient can openly share all current therapies and express their goals without fear of dismissal.

Option talk means walking through the evidence together, including both the potential benefits and the documented risks, for the therapies the patient is considering or already using.

Decision talk means collaboratively agreeing on which therapies to continue, modify, or step back from, with a clear documented plan for monitoring progress.

Patients who feel their physicians use participatory decision-making are more likely to disclose CAM use — which creates a positive cycle where openness encourages more openness.

A note on biologically-based CAM: the regulatory gap

Unlike pharmaceutical drugs, dietary supplements in Australia are regulated by the TGA (Therapeutic Goods Administration) as therapeutic goods. The TGA requires manufacturers to demonstrate safety and efficacy before products can be listed or registered — placing responsibility on manufacturers rather than consumers to ensure product quality.

However, this regulatory framework means the label on a supplement bottle may not always accurately reflect what's inside it. Herbal products vary in composition, lack standardisation in dosing and active components, and carry real risks of mislabelling and contamination. We encourage patients to choose products bearing TGA approval or listing, or those verified by the Complementary Medicines Evaluation Committee (CMEC) — a straightforward step that adds a meaningful layer of reassurance.

Key takeaways

The disclosure gap is the primary safety risk. Across multiple studies, 63 to 72 percent of CAM users did not disclose use to their doctor. Systematic intake screening — rather than waiting for patients to volunteer the information — is the most reliable way to address this.

Drug-herb interactions are clinically significant and widely underdetected. The combination of ginkgo, garlic, and ginseng with anticoagulants carries the highest documented interaction risk in older adults, and roughly half of herbal product users never discuss their use with a healthcare professional.

Credentialing standards for CAM practitioners vary dramatically by state and territory. There is no standardised national system. Patients need to verify registration independently using AHPRA and state-based health practitioner boards, and we're here to help guide that process.

Shared decision-making is the structural solution. Disclosure of CAM use is a necessary prerequisite for the kind of participatory care that drives better outcomes.

Outcome monitoring must be prospective and structured. Integrating CAM without a documented monitoring plan — validated symptom scales, laboratory follow-up for high-risk supplements, adverse event reporting — turns a potentially beneficial adjunct into an uncontrolled variable.

Conclusion

Safe CAM integration isn't about choosing between conventional medicine and complementary therapies. It's about building a care environment where all therapies are visible, properly evaluated, and thoughtfully coordinated. The evidence is clear that most patients are already using CAM alongside their conventional treatments. The real question is whether that use is happening transparently, with clinical oversight, or quietly in a parallel track that increases risk without anyone knowing.

The six-step protocol outlined here — defining goals, evaluating evidence, screening for interactions, vetting practitioners, disclosing fully, and monitoring outcomes — gives patients and clinicians a clear, repeatable framework that respects patient autonomy while keeping safety front and centre. The shared decision-making model isn't an add-on; it's what makes this framework work in real clinical practice. At Tyack Health, we're committed to supporting patients and clinicians in navigating this process with confidence, clarity, and genuine care.
