What Are Third-Party Cases in the SCA?

A third-party consultation is any case where the person you are consulting with is not the patient. The RCGP includes these because they reflect the reality of general practice: GPs regularly consult with parents about children, adult children about elderly parents, carers about the people they look after, and colleagues about professional or personal concerns.

These cases test skills that standard doctor-patient consultations do not: navigating confidentiality when someone asks about another person's care, managing the tension between the third party's concerns and the patient's autonomy, and adapting your consultation style for someone who is an advocate rather than a patient.

The third party may be a parent consulting about a child (where you are consulting with someone who has legal responsibility for the patient), an adult child consulting about an elderly parent (where confidentiality is more complex because the patient is a competent adult), a carer raising concerns about a patient's welfare or treatment, a relative reporting worrying behaviour or requesting information, or a colleague seeking help for a professional or personal issue.

Each of these scenarios creates different dynamics. The skills they share are confidentiality management, advocacy awareness, and the ability to consult effectively with someone whose emotional investment in the outcome is high.

Whose Interests Am I Serving?

This is the question you should ask yourself in the reading time before every third-party case. The answer determines how you structure the entire consultation.

When the third party IS the patient: A carer who comes in with headaches caused by caregiver stress. A parent who is sleep-deprived and anxious. A colleague who needs help with their own health issue. In these cases, the person in front of you is the patient, and the consultation follows the standard framework. The twist is that their presenting complaint is usually connected to someone else's care, so the psychosocial exploration needs to cover the caregiving context.

Practise this with Migraine and Caregiver Stress. The patient presents with migraines, but the real issue is the unsustainable burden of caring for a relative. If you treat only the migraines, you miss the point.

When the third party is advocating for someone else: A son worried about his mother's memory. A parent concerned about their child's development. In these cases, you are serving two interests simultaneously: the third party's concern and the absent patient's autonomy. The consultation needs to address both.

When the third party raises a safeguarding concern: A relative worried about potential abuse. A colleague disclosing fitness to practise issues. In these cases, the patient's safety overrides normal confidentiality rules, and your legal and ethical obligations change. See the safeguarding section below.

The Confidentiality Framework

Confidentiality is the most common pitfall in third-party cases. The examiner is specifically watching whether you navigate it correctly.

The default position: You cannot share a patient's medical information with a third party without the patient's explicit consent. This applies even when the third party is a close relative, a spouse, or an adult child. "I understand your concern about your mother, and I want to help. However, I'm not able to share details of her medical care without her permission" is the correct starting position.

What you can do: You can listen to the third party's concerns (listening does not breach confidentiality). You can provide general health information that is not specific to the patient. You can offer to involve the patient in a three-way conversation. You can encourage the third party to discuss their concerns directly with the patient.

What you must not do: Share specific diagnoses, test results, medication details, or treatment plans without consent. Confirm or deny information the third party already has ("Your mother told me she has diabetes"). Assume consent because the relationship is close.

When confidentiality is overridden: When there is a risk of serious harm to the patient or others. When there is a safeguarding concern involving a child or vulnerable adult. When there is a legal obligation (such as a notifiable disease or fitness to drive). In these cases, you may need to share information without consent, but you should document your reasoning and, where possible, inform the patient that you are doing so.

Practise navigating confidentiality with Worsening Memory: Son Concerned About Mother. The son has legitimate concerns about his mother's cognitive decline. He wants to know what is happening with her care. You need to address his concern without breaching his mother's confidentiality, while also assessing whether there is a safeguarding element (is she at risk living alone?).

Carer Consultations

Carers occupy a unique position. They often know the patient better than you do, they are emotionally invested in the outcome, and they may be struggling with their own health as a result of their caring role.

In the SCA, carer consultations typically fall into two categories. The first is the carer consulting about the patient: a daughter worried about her father's medication, a spouse concerned about behavioural changes, a carer reporting that a patient's condition is deteriorating. The second is the carer consulting as a patient: presenting with their own symptoms (headaches, insomnia, low mood) that are directly related to the caregiving burden.

For the first category, your approach needs three elements. Acknowledge the carer's role and the difficulty of what they are doing. Address their specific concern within the confidentiality framework. Offer practical next steps that involve the patient where possible.

For the second category, treat the carer as the patient but explore the caregiving context as the primary psychosocial factor. "How is the caring affecting you?" is often the most important question in the consultation. See our story-led consulting guide for how LIIF (Life, Impact, Interest, Feelings) helps uncover the full picture.

Accidental Medication Overdose in the Elderly tests a common scenario: a carer reports that the patient accidentally took too much medication. You need to assess the clinical risk, address the carer's guilt and anxiety, and put a plan in place to prevent recurrence. The consultation is with the carer, but the management plan is about the patient.

Parental Consultations

Parental consultations are the most common type of third-party case in the SCA because paediatric cases inherently involve the parent as the primary historian and decision-maker.

The parent is usually anxious, often sleep-deprived, and always emotionally invested. They may have researched their child's symptoms online and arrived with a specific diagnosis in mind. Or they may be overwhelmed and looking for reassurance that their child is developing normally.

The key skills are the same as in health anxiety cases (validate before reassure) but with an additional element: respecting the parent's expertise about their own child while guiding them with your clinical knowledge.

"You know [child's name] better than anyone. Tell me what you've been noticing." This opening validates the parent, gathers data, and sets a collaborative tone. It is far more effective than "What seems to be the problem?"

Parental Concern: Autism in a Toddler is a sensitive case where the parent has noticed developmental differences and is seeking either reassurance or a referral. The consultation tests whether you can take the concern seriously, conduct a focused developmental assessment through history, and explain the referral pathway without either dismissing the parent or creating unnecessary alarm.

Psychotic Features in a Teenager adds complexity: the parent is reporting concerning behaviour in an adolescent. This tests your ability to gather information from a third party about a patient who has their own autonomy (Gillick competence considerations), and to determine whether the situation requires urgent action.

Consulting with a Healthcare Professional

Colleague consultations are among the most challenging cases in the SCA because they test a skill that most trainees have little experience with: consulting with a peer who has professional knowledge, professional boundaries, and potentially fitness-to-practise implications.

The most common scenario is a colleague who presents with a personal health issue that may affect their professional practice: substance misuse, mental health problems, or physical symptoms they have been ignoring because they are too busy to seek help.

The tension in these cases is between supporting the colleague as a patient and fulfilling your professional obligations. If a colleague discloses substance dependence, you have a GMC duty that may override your usual duty of confidentiality. The examiner is watching whether you acknowledge both dimensions: the human being in front of you who needs help, and the professional obligation to ensure patient safety.

GP Colleague with Tramadol Dependency is the definitive case for this skill. Your colleague has come to you because they trust you, and they are disclosing something that could end their career. You need to be compassionate, non-judgemental, and honest about the professional implications. This is where naming the dilemma is critical: "I want to support you, and I also have a professional responsibility to make sure patients are safe. Let me explain what that means in practice."

When Third-Party Becomes Safeguarding

Some third-party consultations cross the line into safeguarding territory, and recognising that moment is one of the things the SCA specifically tests.

A son concerned about his mother's memory is a carer consultation. A son concerned that his mother is being financially exploited by a live-in carer is a safeguarding consultation. A parent bringing in a child with a rash is a paediatric consultation. A parent bringing in a child with unexplained bruising and an inconsistent story is a safeguarding consultation.

The difference is whether there is a risk of harm. When you identify a safeguarding concern, three things change:

Confidentiality rules change. You may need to share information without the patient's consent if there is a risk of harm to a child or vulnerable adult. You should explain to the third party what you are doing and why, but their consent is not required.

Your documentation obligations change. Record exactly what was said, by whom, and what actions you took. Use the patient's exact words where possible, not your interpretation.

Your referral pathway changes. Safeguarding concerns require specific actions: contacting social services, speaking to the named safeguarding lead, or in urgent cases, contacting the police. Know the pathway. The examiner will check whether you know the correct next step.

For detailed guidance on safeguarding cases, see our SCA Safeguarding Cases guide. FGM Safeguarding: Concerned Relative tests whether you can identify a safeguarding concern from a relative's disclosure, understand your legal obligations (FGM is a mandatory reporting offence), and act appropriately while managing the relative's distress. Domestic Violence: Wrist Injury tests the same skills in a different context: recognising the signs, asking sensitively, and knowing the referral pathway.

Common Mistakes in Third-Party Cases

Mistake 1: Sharing too much. The most common error is breaching confidentiality by sharing the patient's medical details with the third party. Even well-intentioned sharing ("Your mother's dementia has been getting worse") is a breach if the patient has not consented. The examiner will fail you on this.

Mistake 2: Sharing too little. The opposite error. Hiding behind confidentiality to avoid addressing the third party's legitimate concern. "I can't discuss that" without offering anything constructive leaves the third party feeling dismissed and unhelped. The skill is finding what you can do within the confidentiality framework: listen, provide general information, offer to involve the patient, suggest next steps.

Mistake 3: Treating the third party as an obstacle. Some trainees treat the carer or relative as an inconvenience rather than a resource. The third party often has valuable clinical information (they have observed the patient at home, they have noticed changes, they can describe the patient's daily functioning). Engaging with them respectfully yields better data and better rapport.

Mistake 4: Missing the safeguarding trigger. In cases where the third-party consultation crosses into safeguarding territory, some trainees continue consulting as if it were a standard carer concern. If a relative describes behaviour that suggests abuse, neglect, or exploitation, you need to shift into safeguarding mode. The examiner is specifically watching for this transition.

Mistake 5: Ignoring the third party's own wellbeing. Carers, parents, and concerned relatives are often struggling themselves. Asking "How are you coping with all of this?" demonstrates person-centred care that extends beyond the absent patient. It scores Relating to Others marks and may reveal a clinical concern in the third party that needs addressing.
