Service Delivery Models and Telehealth

The traditional model, one counselor and one family in a room for an hour, cannot meet demand. Referral volume has grown far faster than the workforce, and the profession's response has been a set of alternative delivery models, each of which changes what the encounter can accomplish. Choosing a model is a clinical decision, not only a logistical one.

• Telehealth is now a standard rather than an exceptional model. It removes geographic barriers, reduces travel burden and time off work, and reaches patients who would otherwise go unseen. It also loses some nonverbal information, depends on broadband the patient may not have, and requires attention to whether the patient has a private place to take the call.
• Licensure follows the patient. For telehealth the governing jurisdiction is generally the state where the patient is physically located at the time of the encounter, which makes multi-state practice a licensing question before a technology question.
• Telephone counseling remains useful and is not merely degraded video. It is accessible without equipment or bandwidth, and trials in hereditary cancer have found outcomes broadly comparable to in-person counseling on knowledge and satisfaction.
• Group counseling delivers pre-test education to several patients at once and adds peer effect, which some patients value highly. It is efficient for standardized content and unsuitable for results disclosure or for anything requiring disclosure of private history.
• Mainstreaming has the treating clinician, typically an oncologist or cardiologist, order testing directly, with genetic counseling reserved for positive or complex results. It substantially increases testing throughput and shifts consent quality onto clinicians with limited genetics training, which is the tradeoff to watch.
• Tiered and triaged models route straightforward cases to lower-intensity pathways and reserve full sessions for complex ones. The risk is in the triage rule, which determines who is under-served.
• Digital tools and chatbots deliver standardized pre-test education, collect family history, and obtain consent, reserving counselor time for interpretation and decisions. Evidence on knowledge outcomes is reasonable; evidence on psychosocial outcomes is thinner.
• Match the model to the task. Standardized pre-test education is well suited to group, digital, or telephone delivery. A complex results disclosure, a distressed patient, or a difficult family decision is not.
• Equity cuts both ways. Telehealth expands access for rural patients and reduces it for patients without broadband, devices, or privacy at home. Assuming a model is universally more equitable is a mistake in either direction.
• Documentation and privacy requirements do not relax with the model. The platform must be appropriate for protected health information, and the patient's location and the presence of others should be confirmed and recorded.

• A patient four hours from the nearest genetics center is seen by video. The visit happens, where an in-person referral had already been declined twice for travel reasons. The counselor confirms her location at the start, because the patient is visiting family across a state line, which changes which license applies.
• A cardiology clinic adopts mainstreaming for cardiomyopathy panels. Testing volume triples and counselor time shifts to positive results. Six months in, an audit finds several patients who consented without understanding that a variant of uncertain significance was possible, and the fix is clinician education plus a standardized consent tool rather than abandoning the model.
• A group pre-test session for hereditary cancer works well for eight patients until one begins describing her mother's death in detail. The counselor acknowledges her and offers an individual follow-up, because the group format cannot hold that safely for her or for the others.
• A patient joins a telehealth results session from a car in a parking lot with a colleague nearby. The counselor confirms privacy before disclosing, and reschedules rather than proceeding.

• Do not deliver a difficult result in a format that cannot hold it. Group and asynchronous formats are wrong for disclosure that may be distressing.
• Do not assume telehealth is universally more accessible. Broadband, devices, and privacy are unequally distributed.
• Do not overlook licensure. The patient's location at the time of the encounter generally governs.
• Do not adopt mainstreaming without a consent quality plan. The predictable failure is patients consenting without understanding what an uncertain result means.
• Do not confirm privacy after starting the disclosure. Ask first, every time.
