When a GP dismisses early symptoms and the diagnosis comes too late: what does NSW law say about delayed diagnosis negligence?
That experience — of presenting with symptoms, being reassured or redirected, returning again, and eventually receiving a diagnosis that should have come far sooner — is not rare. It has a clinical name: diagnostic delay. And it has a legal dimension that most people in that situation do not know exists.
This article examines what general practitioners are required to do when a patient presents with early symptoms, where that process breaks down, and what NSW law says when the breakdown causes measurable harm.
What GP-level diagnostic responsibility looks like — and how common failure is
General practitioners occupy a specific and demanding position in the Australian health system. They are the first point of contact for the vast majority of patients presenting with new or evolving symptoms. That position carries a defined clinical and legal responsibility: to take a history, examine the patient, form a differential diagnosis — a list of possible explanations ranked by likelihood and seriousness — and either reach a working diagnosis or refer the patient to someone who can.
The Royal Australian College of General Practitioners defines this responsibility in its curriculum and standards as requiring a systematic approach to undifferentiated presentations. “Undifferentiated” means the GP does not yet know what is wrong. That is not a reason to dismiss the patient. It is the clinical situation the GP is trained to manage.
Diagnostic error in general practice is not a marginal problem. According to a 2016 study published in the BMJ Quality and Safety journal, diagnostic errors affect approximately 5% of adults seeking outpatient care in developed countries — and roughly half of those errors have the potential to cause serious harm.1 Australian data from the Australian Commission on Safety and Quality in Health Care confirms that diagnostic error is one of the leading categories of preventable patient harm in primary care settings.2
For a plain-language explanation of how symptoms are assessed and what patients can expect from a GP consultation, Healthdirect Australia provides accessible condition-specific information.
What it requires: GPs must maintain a systematic approach to clinical assessment, including taking an adequate history, performing an appropriate physical examination, forming a differential diagnosis, and documenting the clinical reasoning that supports their management plan. Where a diagnosis cannot be confirmed, the GP must implement a safety-netting strategy — a clear plan communicated to the patient about what symptoms should prompt return, and within what timeframe.
Why this matters: A GP who fails to document clinical reasoning, fails to form a differential diagnosis, or fails to safety-net a patient with unresolved symptoms has departed from the standard the RACGP sets for its members — and that departure can constitute a breach of the legal standard of care.
The standard of care — what a GP is legally required to do
The “standard of care” is the legal benchmark against which a clinician’s conduct is measured. In plain terms, it asks: what would a reasonably competent general practitioner, with the same training and in the same clinical circumstances, have done? Not the best GP in Australia. Not a specialist. A competent GP, acting with reasonable care and skill.
In NSW, that standard is shaped by the Civil Liability Act 2002 (NSW) and by the body of case law that has developed around it. Section 5O of that Act provides a defence for clinicians who acted in a manner that was widely accepted by peer professional opinion as competent practice. But that defence has limits — and those limits matter enormously in GP dismissal cases.
The High Court’s decision in Rogers v Whitaker (1992) 175 CLR 479 established that Australian courts do not simply defer to what the medical profession says is acceptable practice.3 A court can find that a practice, even if widely followed, does not meet the standard of care if it is not reasonable. That principle applies directly to GP dismissal cases: the fact that many GPs send patients away without investigation does not make that practice legally defensible if the clinical picture called for more.
What it requires: GPs must apply a structured diagnostic reasoning process to every presentation, including: identifying red flag symptoms that require urgent investigation or referral, forming and documenting a differential diagnosis, and establishing a clear safety-netting plan when a definitive diagnosis is not reached at the first consultation.
Why this matters: A GP who fails to identify documented red flag symptoms, or who discharges a patient without a safety-netting plan, has failed to meet the standard the profession’s own curriculum requires — and that failure is directly relevant to whether a breach of the legal standard of care occurred.
What “safety-netting” means and why its absence matters
Safety-netting is a specific clinical obligation. It requires the GP to tell the patient, in clear terms, what symptoms should prompt them to return, how quickly they should return if those symptoms develop, and what the GP will do if the situation does not resolve. A GP who says “come back if it gets worse” without specifying what “worse” looks like, or without documenting that advice, has not safety-netted the patient. That distinction is not semantic. In a delayed diagnosis claim, the absence of documented safety-netting is often one of the clearest indicators that the GP’s management fell below the required standard.
-
1First symptom presentation
Patient presents with early, non-specific symptoms. Standard required: Full history, physical examination, differential diagnosis formed and documented. Red flag symptoms identified and acted upon. Safety-netting plan communicated and recorded. -
2First dismissal or misattribution
GP attributes symptoms to a benign cause without adequate investigation. Patient is reassured and sent home. What went wrong: No differential diagnosis documented. No red flag assessment. No safety-netting. Patient not told when or why to return. -
3Return visit(s) — symptoms escalating
Patient returns, often to the same GP or a different GP at the same practice. Symptoms have persisted or worsened. Standard required: Persistence of symptoms across multiple visits is itself a red flag. The GP must reconsider the differential diagnosis, order investigations, or refer. Anchoring on the prior benign diagnosis at this point is a clinical error. -
4Second or third dismissal
GP again reassures or attributes symptoms to the same benign cause. No investigations ordered. No referral made. What went wrong: Anchoring bias — the GP’s initial diagnosis has become a fixed frame that new clinical information cannot displace. The patient’s credibility is implicitly discounted. -
5Emergency presentation or specialist referral
The patient presents to an emergency department, or a different clinician finally orders investigations. The correct diagnosis is made — often at a more advanced stage than it would have been had the GP acted earlier. The harm: Treatment options that existed at Stage 1 or 2 are no longer available, or are less effective. The patient’s prognosis has worsened. -
6Confirmed diagnosis — delayed
The diagnosis the GP should have reached — or referred for — weeks or months earlier is now confirmed. The question the law asks: what would have been different if the GP had acted at Stage 1 or 2? If the answer is “the patient would have had better treatment options and a better outcome,” causation is engaged.
This timeline represents a common pattern in GP dismissal cases. Individual presentations vary. The legal question at each stage is whether the GP’s response met the standard of care.
Where care breaks down — the specific failure patterns in GP dismissal
GP dismissal of early symptoms does not usually happen because a clinician is careless in a general sense. It happens through specific, identifiable cognitive and structural failures. Understanding those failures matters — not just for legal analysis, but because it explains why so many patients leave a GP consultation feeling that something was wrong with the interaction, even when they cannot name what it was.
Symptom normalisation — the “it’s probably nothing” failure
Symptom normalisation occurs when a GP attributes a patient’s symptoms to a common, benign cause without adequately ruling out more serious alternatives. The GP hears “fatigue and weight loss” and thinks “stress and diet” rather than working through a differential that includes malignancy, thyroid disease, or autoimmune conditions. The clinical reasoning stops at the first plausible explanation.
What should have happened: the GP forms a differential diagnosis, documents it, orders baseline investigations to rule out serious causes, and safety-nets the patient with specific return criteria. What went wrong: the GP reached a reassuring conclusion and stopped. The patient went home. Three months later, the diagnosis that should have been reached at that first visit arrived — at a stage where treatment was harder and outcomes were worse.
The mechanism is cognitive. Clinicians under time pressure — and GP consultations in Australia average approximately 15 minutes4 — are prone to what researchers call “premature closure”: settling on a diagnosis before the clinical picture has been fully assessed. That cognitive tendency does not excuse the failure. The standard of care requires the GP to work through the differential regardless of time pressure.
Demographic dismissal — whose symptoms get taken seriously
The evidence on demographic bias in diagnostic medicine is substantial and consistent. Women presenting with cardiac symptoms are more likely than men to receive a psychiatric or anxiety diagnosis before a cardiac workup.5 Younger patients presenting with serious conditions are more likely to have their symptoms attributed to lifestyle factors. Patients from non-English-speaking backgrounds face higher rates of diagnostic delay across multiple conditions.
Demographic dismissal is not always conscious. A GP may genuinely believe they are applying clinical reasoning when they are in fact applying a statistical heuristic — “this patient doesn’t fit the profile for this condition” — that substitutes population-level assumptions for individual clinical assessment. The law does not excuse that substitution. The standard of care requires the GP to assess the patient in front of them, not the average patient in a demographic category.
She went to her GP three times in four months. Each time, she was told her symptoms were consistent with anxiety. Nobody ordered a blood test. Nobody referred her to a specialist. When she finally presented to an emergency department, the diagnosis was stage three cancer. The question the law asks is not whether the GP meant well. It asks whether a competent GP, presented with those symptoms on those three occasions, would have done more.
Anchoring on a prior diagnosis
Anchoring bias occurs when a clinician’s initial diagnosis becomes a fixed frame that subsequent clinical information cannot displace. Once a GP has recorded “irritable bowel syndrome” or “tension headache” in a patient’s notes, every subsequent presentation of abdominal pain or headache gets filtered through that prior label. New symptoms that do not fit the prior diagnosis are minimised or attributed to the same cause.
This failure is particularly dangerous across multiple consultations. The RACGP’s own guidance on diagnostic reasoning identifies anchoring as one of the most common sources of diagnostic error in general practice.6 A GP who reviews a patient’s notes, sees a prior diagnosis, and fails to reconsider that diagnosis in light of new or persistent symptoms has not met the standard of care. Persistence of symptoms across multiple visits is itself a clinical signal that the prior diagnosis may be wrong — and the standard requires the GP to treat it as such.
Failure to safety-net — the gap between consultations
Safety-netting failure is the most structurally invisible of the four patterns — and often the most legally significant. When a GP cannot reach a definitive diagnosis at a single consultation (which is clinically normal and expected), the standard of care requires a specific response: tell the patient what to watch for, tell them when to return, document that advice, and in some cases arrange a follow-up appointment proactively.
A GP who says “let’s see how you go” and records nothing in the notes has failed to safety-net. If the patient’s condition deteriorates in the interval between consultations, and the patient did not return because they believed the GP had told them it was nothing serious, that failure in communication and documentation becomes directly relevant to causation. The patient did not return because the GP gave them no reason to return urgently. That is not the patient’s failure. It is the GP’s.
What happened: A child presented with symptoms that a doctor failed to adequately investigate. The correct diagnosis was delayed, and the child suffered permanent neurological harm. The question before the High Court was whether the loss of a chance of a better outcome could ground a damages claim.
What the court found: The High Court held that damages for loss of a chance of a better medical outcome are not recoverable in negligence under Australian law — the plaintiff must establish, on the balance of probabilities, that the negligent act or omission caused the harm. However, the case confirmed that where a delayed diagnosis demonstrably worsened the patient’s outcome, causation can be established.
Why this matters: In GP dismissal cases, the causation question is central. The plaintiff must show that earlier diagnosis would, on the balance of probabilities, have produced a better outcome — not merely that it might have. Medical evidence about what treatment was available at the earlier stage, and what that treatment would have achieved, is essential.
The Australian Commission on Safety and Quality in Health Care has identified diagnostic error as a national patient safety priority, publishing guidance on the cognitive and systemic factors that contribute to missed and delayed diagnoses in primary care settings.
| Failure pattern | What the GP should have done | What went wrong | Harm that resulted |
|---|---|---|---|
| Symptom normalisation | Formed a differential diagnosis including serious causes; ordered baseline investigations; documented clinical reasoning; safety-netted the patient. | Attributed symptoms to a benign cause at the first plausible explanation; stopped clinical reasoning; sent the patient home without investigation or documented plan. | Serious condition progressed undetected; treatment options available at early stage were no longer available by the time of correct diagnosis. |
| Demographic dismissal | Assessed the individual patient’s clinical presentation on its own merits; applied red flag criteria regardless of age, sex, or background. | Applied population-level assumptions to an individual patient; attributed symptoms to anxiety, lifestyle, or stress without adequate clinical basis; failed to investigate. | Delayed diagnosis of a condition that disproportionately affects the dismissed demographic; harm compounded by repeated dismissal across multiple consultations. |
| Anchoring on prior diagnosis | Treated persistence of symptoms across multiple visits as a clinical signal requiring reassessment; reconsidered the differential diagnosis; ordered further investigations or referred. | Filtered new clinical information through the prior diagnosis; attributed persistent or worsening symptoms to the same benign cause; failed to reconsider. | Underlying condition advanced while the patient was managed under an incorrect diagnosis; harm attributable to the period of anchoring rather than the initial diagnostic uncertainty. |
| Failure to safety-net | Communicated specific return criteria to the patient; documented the safety-netting advice; arranged follow-up where clinically indicated. | Gave vague or no return instructions; recorded nothing in the notes; left the patient without a clear understanding of when to seek further care. | Patient did not return when symptoms worsened because the GP had given them no reason to; condition deteriorated in the interval; harm attributable to the gap in communication. |
These patterns are drawn from documented failure modes in Australian general practice. Multiple patterns often occur in the same case.
The legal framework in NSW
Medical negligence claims in NSW are governed primarily by the Civil Liability Act 2002 (NSW). That Act sets out the legal tests for breach, causation, and damages. Understanding how those tests apply to GP dismissal cases requires working through each element carefully — because the law does not treat every bad outcome as a legal wrong, and it does not treat every clinical error as a compensable breach.
Duty of care
A general practitioner owes a duty of care to every patient they agree to treat. That duty arises the moment the clinical relationship is established — when the patient presents and the GP undertakes to assess them. The duty is not limited to the consultation itself. It extends to the advice the GP gives about follow-up, the referrals they make or fail to make, and the safety-netting instructions they provide or fail to provide.
Breach — section 5O and its limits
Section 5O of the Civil Liability Act 2002 (NSW) provides that a clinician does not breach the standard of care if they acted in a manner that was widely accepted by peer professional opinion as competent practice at the time — unless that opinion is irrational. This is the peer professional opinion defence. It is important, but it is not a shield against all claims.
Two limits apply directly to GP dismissal cases. First, the defence requires that the peer opinion be genuinely held and not irrational — a court can reject a clinical practice as falling below the standard even if some clinicians would endorse it. Second, the defence does not apply where the GP’s conduct departed from the profession’s own published guidelines. A GP who failed to follow the RACGP’s documented standards for safety-netting or differential diagnosis cannot rely on section 5O to defend that failure.
Causation — section 5D and the “but for” test
Section 5D of the Civil Liability Act 2002 (NSW) requires the plaintiff to establish causation: that the breach caused the harm. The primary test is the “but for” test — but for the GP’s failure, would the harm have occurred? In delayed diagnosis cases, this translates to: but for the GP’s failure to diagnose or refer at the earlier stage, would the patient’s outcome have been better?
That question requires medical evidence. An expert clinician must be able to say, with sufficient certainty, what treatment was available at the earlier stage and what that treatment would have achieved. Where the evidence supports a finding that earlier diagnosis would have produced a materially better outcome — a lower cancer stage, a less invasive treatment, a preserved function — causation is established.
What happened: A patient presented to a GP with symptoms that the GP failed to adequately investigate. The patient subsequently suffered a serious cardiac event. The question was whether the GP’s failure to refer or investigate caused the harm.
What the court found: The NSW Court of Appeal confirmed that causation in medical negligence cases requires the plaintiff to establish, on the balance of probabilities, that the defendant’s breach caused the harm — and that this assessment must be grounded in expert medical evidence about what would have happened with timely intervention.
Why this matters: GP dismissal cases turn on causation evidence. The legal question is not whether the GP made an error — it is whether that error, on the balance of probabilities, caused the harm the patient suffered. Expert evidence about the natural history of the condition and the effect of earlier treatment is essential.

When GP dismissal of early symptoms may amount to medical negligence
Not every delayed diagnosis is a legal wrong. The law recognises that some conditions are genuinely difficult to diagnose at early stages, that symptoms can be non-specific, and that even a competent GP working carefully will sometimes reach the wrong conclusion. The question is not whether the GP was wrong. It is whether the GP’s process — the history they took, the examination they performed, the differential they formed, the investigations they ordered, the safety-netting they provided — met the standard of a competent practitioner.
When red flag symptoms were present and ignored
Every clinical specialty publishes red flag criteria — specific symptoms or combinations of symptoms that require urgent investigation or referral. A GP who encounters documented red flag symptoms and fails to act on them has departed from the standard in a way that is difficult to defend. The red flags exist precisely because the profession has identified those presentations as requiring a specific clinical response. Ignoring them is not a judgment call. It is a failure to apply the standard the profession has set for itself.
If a patient presented with unexplained weight loss, night sweats, and a palpable lymph node — all documented in the GP’s notes — and the GP recorded “reassured, no further action,” that record tells a clear story. The clinical picture called for investigation. The GP did not investigate. The diagnosis came later, at a more advanced stage. That sequence engages both breach and causation.
When the patient returned multiple times without escalation
A single consultation with an uncertain outcome is not, by itself, a breach. But a pattern of repeated presentations with the same or worsening symptoms, each met with the same reassurance and no escalation, is a different clinical picture. The RACGP’s own guidance identifies persistence of symptoms across multiple consultations as a clinical signal requiring reassessment. A GP who sees the same patient three times in two months with the same complaint and does not reconsider the differential has not met the standard.
The legal significance of multiple consultations is also evidentiary. Each consultation is a documented clinical encounter. Each record either shows a GP who was actively reassessing and reasoning, or a GP who was applying the same label to a changing clinical picture. Those records are the foundation of the legal analysis.
When no safety-netting was documented
The absence of documented safety-netting advice is both a clinical failure and a legal one. Clinically, it means the patient left the consultation without the information they needed to make a safe decision about when to return. Legally, it means the GP cannot demonstrate that they met the standard the RACGP requires. In a delayed diagnosis claim, the absence of safety-netting documentation is often the clearest evidence that the GP’s management fell below the required standard — because it is the absence of something that should always be present.
When referral was indicated and not made
General practitioners are not expected to diagnose every condition. They are expected to recognise when a presentation exceeds their diagnostic capacity and to refer the patient to a specialist who can investigate further. A GP who encounters a presentation that a competent practitioner would refer — because the symptoms are persistent, because the red flags are present, because the differential includes serious conditions that require specialist investigation — and who fails to refer, has breached the standard of care.
The referral obligation is not triggered only by certainty. It is triggered by clinical uncertainty combined with the possibility of serious harm. A GP does not need to be sure the patient has cancer to refer them for investigation. They need to recognise that cancer is on the differential and that investigation is required to rule it out.
The three elements of negligence applied to GP dismissal
For a GP dismissal claim to succeed in NSW, three elements must all be established: duty of care, breach of that duty, and causation of harm. All three must be present. A breach without causation — a GP who failed to meet the standard but whose failure made no difference to the outcome — does not give rise to a compensable claim. Understanding how each element applies to this specific type of case is essential before any legal analysis can begin.
A GP who assessed a patient with genuinely non-specific symptoms, formed and documented a reasonable differential diagnosis, ordered appropriate baseline investigations, and safety-netted the patient — but whose diagnosis was nonetheless delayed because the condition presented atypically — has not breached the standard of care.
A GP who saw a patient three times over two months with persistent and worsening symptoms, recorded no differential diagnosis, ordered no investigations, provided no documented safety-netting, and made no referral — and whose patient was subsequently diagnosed with a serious condition at an advanced stage — may have breached the standard of care in a way that caused measurable harm.
This is a general educational framework only. Each case depends on its individual facts and circumstances.
Long-term and permanent harm from delayed diagnosis
The harm from a delayed diagnosis is rarely limited to the period of the delay itself. When a serious condition goes undiagnosed because a GP dismissed early symptoms, the harm compounds across every dimension of the patient’s life — physical, psychological, financial, and relational.
Physical consequences
The physical consequences depend on the underlying condition, but the pattern is consistent: earlier diagnosis produces better outcomes. A cancer diagnosed at stage one has a fundamentally different prognosis from the same cancer diagnosed at stage three. A cardiac condition identified and managed at first presentation carries a different risk profile from the same condition that progressed undetected for six months. An autoimmune condition treated early causes less organ damage than one that was dismissed as stress for two years.
Beyond the primary condition, delayed diagnosis often produces secondary physical harm. Patients who underwent more aggressive treatment because their condition was diagnosed late — chemotherapy rather than surgery, amputation rather than limb-sparing procedures, dialysis rather than medication management — carry the physical burden of that treatment for the rest of their lives. That burden is directly attributable to the delay.
Psychological consequences
The psychological harm from repeated dismissal is distinct from the harm caused by the underlying condition. Patients who were told repeatedly that their symptoms were nothing serious, and who later received a serious diagnosis, frequently report a specific form of distress: the knowledge that they were right, that they knew something was wrong, and that the people they trusted to help them did not listen.
Research published in the Journal of General Internal Medicine found that patients who experienced diagnostic delay reported significantly higher rates of anxiety, depression, and loss of trust in the health system compared with patients who received timely diagnoses — independent of the severity of the underlying condition.7 That psychological harm is a recognised head of damage in a medical negligence claim.
Financial consequences
The financial impact of a delayed diagnosis is often substantial and long-lasting. Patients who required more aggressive treatment because of the delay face higher treatment costs, longer recovery periods, and greater loss of income. Those who sustained permanent impairment face ongoing costs: specialist appointments, medications, rehabilitation, home modifications, and in some cases the cost of paid care that family members would otherwise have provided.
Lost income is often the largest single component of a damages claim in delayed diagnosis cases. A person who was working full-time before their diagnosis, and who can no longer work — or can only work reduced hours — because of harm that was compounded by the delay, has suffered an economic loss that extends across their entire working life. Quantifying that loss requires economic expert evidence, but the legal framework in NSW provides for its recovery.
What compensation covers in NSW
Compensation in a medical negligence claim in NSW covers two broad categories: general damages and special damages. General damages compensate for pain, suffering, and loss of enjoyment of life. Special damages compensate for specific financial losses — past and future medical expenses, lost income, and the cost of care.
Under section 16 of the Civil Liability Act 2002 (NSW), non-economic loss (general damages) is only recoverable if the severity of the harm reaches a statutory threshold — currently assessed as a percentage of a “most extreme case.” This threshold means that minor or short-term harm may not give rise to a general damages award, even where a breach occurred. Serious, permanent, or life-altering harm will typically exceed the threshold.
The Limitation Act 1969 (NSW) imposes a three-year limitation period on personal injury claims. In delayed diagnosis cases, that period generally runs from the date the plaintiff knew, or ought reasonably to have known, that they had suffered harm as a result of the GP’s conduct — not necessarily from the date of the original consultation. Where the harm was latent — where the patient did not and could not reasonably have known about the connection between the GP’s failure and their injury — the limitation period may run from the date of discovery. Time limits in these cases are complex and require careful legal analysis.
| Severity of harm | Indicative range (NSW) | Key factors |
|---|---|---|
| Moderate injury with recovery | $50,000–$150,000 | Duration of pain, treatment required, time off work |
| Serious injury with lasting effects | $150,000–$500,000 | Permanent impairment, ongoing treatment, care needs |
| Severe or life-changing injury | $500,000–$2,000,000+ | Catastrophic loss of function, lifetime care, lost earnings |
These figures are general reference ranges only. Each case turns on its own evidence — medical records, expert clinical opinion, and economic reports that quantify the actual loss.
How to think about your own situation
The questions below are not a legal test. They are prompts to help you think clearly about whether your experience may warrant further examination.
These questions are not a legal test. But the pattern they reveal — when several of them point in the same direction — is often the starting point for a proper examination of whether the standard of care was met. The medical records from those consultations are the foundation of that examination. What the GP recorded, what they did not record, and what the clinical picture at each consultation actually showed are the questions that a legal and expert clinical review will answer.
For a detailed explanation of how medical negligence claims proceed in NSW — from the initial review of records through to expert evidence and resolution — see Reframe Legal — How Medical Negligence Claims Work in NSW.
Uncertainty is normal — and it is not evidence that nothing went wrong
Most people who experienced repeated dismissal of their symptoms carry a specific kind of doubt: they wonder whether they are being unfair to the GP, whether they are misremembering, whether the GP was doing their best with what they had. That doubt is rational. It is the natural response to a confusing experience in which a trusted professional repeatedly told them that nothing was seriously wrong.
The law does not ask whether the GP was trying their best. It asks whether the GP’s conduct met an objective standard — what a competent practitioner in the same circumstances would have done. That is an external, evidence-based question. It is answered by reviewing the medical records, applying the clinical guidelines, and obtaining expert opinion from a practitioner in the same specialty. The patient’s certainty, or lack of it, is not the measure.
In my view, the most important thing to understand about this area of law is that the standard of care is not a subjective test. A GP who genuinely believed they were doing the right thing, but who failed to form a differential diagnosis, failed to document their reasoning, and failed to safety-net their patient, has still fallen below the standard. Good intentions do not substitute for competent clinical process. The law measures the process, not the intention.
Many people wait a long time before seeking any kind of examination of what happened to them — often because they doubt themselves, or because those around them discouraged them from asking questions. That delay is understandable. But it has legal consequences: the limitation period in NSW runs regardless of whether the patient has sought legal advice, and in some cases the window for a claim may be narrower than people realise.

Dr Rosemary Listing is a lawyer with a PhD in law, specialising in medical negligence. Her legal practice concentrates on cases where clinical care in NSW failed to meet the standard the law and the profession require. Her doctoral research and legal practice have given her a rigorous command of the clinical standards against which negligent conduct is measured, and of the evidentiary requirements those claims must satisfy in NSW courts.
Cases involving the GP dismissal of early symptoms sit at a particularly demanding intersection of clinical and legal analysis. The clinical question — whether the GP’s diagnostic process met the standard the RACGP requires — must be answered before the legal question of breach can be addressed. And the legal question of causation — whether earlier diagnosis would have produced a materially better outcome — requires expert clinical evidence about the natural history of the underlying condition and the effect of the delay on treatment options. Neither question is straightforward, and neither can be answered without a careful review of the medical records.
The cases that have reached NSW courts, and the complaints recorded by the Health Care Complaints Commission, reveal a consistent pattern in how GP dismissal failures occur and how they are assessed. The records almost always show the same features: an absence of documented differential diagnosis, a pattern of repeated reassurance without escalation, and a gap between what the clinical picture called for and what the GP actually did. That gap — between what the standard required and what the records show — is where the legal analysis begins.
The people who seek a legal examination of their records in these cases are not looking to blame anyone. They want to understand what happened and whether it could have been different. Many waited a long time before seeking any kind of examination of the facts — often because they doubted themselves, or because those around them discouraged them from asking questions. That doubt is understandable. It does not mean the question is not worth asking.
Dr Listing examines medical records alongside expert clinical opinion and applies the legal standard — not to assign blame, but to give people an honest answer about whether what happened to them met the benchmark the profession sets for itself. That answer, whatever it is, is what most people are actually seeking.
