The Hospital Authority recorded 1,075 serious untoward events in public hospitals during the 2023-24 financial year, a figure that has remained stubbornly high over the past five years. This number, published in the Authority’s Annual Report 2023-2024, includes retained instruments post-surgery, wrong-site operations, and medication errors leading to permanent harm. For patients and families considering a medical negligence claim, the window to act is finite and the procedural hurdles are substantial. The Limitation Ordinance (Cap. 347) sets a three-year limitation period from the date of injury or from the date the plaintiff knew the injury was significant and attributable to the defendant’s conduct. A 2025 amendment to the District Court Ordinance (Cap. 336) raised the jurisdictional limit for personal injury claims from HK$3 million to HK$5 million, meaning more medical negligence cases can now be heard in the District Court rather than the more expensive Court of First Instance. Understanding these structural changes is the first step in deciding whether to pursue a claim.

The Legal Framework for Medical Negligence in Hong Kong

Medical negligence in Hong Kong is a branch of the tort of negligence. The law requires a plaintiff to prove three elements on a balance of probabilities: a duty of care existed, that duty was breached, and the breach caused the plaintiff’s injury or loss.

The Duty of Care and the Bolam Test

The legal duty owed by a medical professional to a patient is well-established. A doctor, nurse, or hospital owes a duty to exercise the skill and care of an ordinary competent practitioner in that field. Hong Kong courts apply the Bolam test, derived from the English case Bolam v Friern Hospital Management Committee [1957] 1 WLR 582. The test asks whether the defendant’s conduct fell below the standard of a responsible body of medical opinion. A practitioner is not negligent simply because one medical opinion differs from another. The Court of Final Appeal in Kwan Wai Ming v The Hospital Authority (2014) 17 HKCFAR 117 confirmed that the Bolam test applies in Hong Kong, with the caveat that the court must still assess whether the medical opinion relied upon is logical and capable of withstanding logical analysis.

Causation and the “But For” Test

Proving causation is often the most difficult element. The plaintiff must show that “but for” the defendant’s breach, the injury would not have occurred. This requires expert medical evidence. The Court of Appeal in Choi Yuk Lin v The Hospital Authority [2005] 1 HKLRD 155 held that a plaintiff must prove causation on a balance of probabilities. A delay in diagnosis, for example, is not actionable unless the plaintiff can show that earlier treatment would have produced a materially different outcome. The court will not assume causation from a breach alone.

The Role of Expert Evidence

No medical negligence claim can proceed without expert evidence. The Rules of the High Court (Cap. 4A, Order 38) require parties to disclose expert reports before trial. The court will typically grant permission for each side to call one expert per specialty. The expert must provide an independent opinion, not act as an advocate for the party instructing them. The Court of Appeal in Sze To Chun Keung v The Hospital Authority [2009] 3 HKLRD 214 emphasised that expert evidence must be directed to the standard of care and causation, not to the ultimate issue of liability.

The Claims Process: From Incident to Trial

The process for a medical negligence claim follows a structured path under the Rules of the District Court (Cap. 336H) or the Rules of the High Court (Cap. 4A). The choice of forum depends on the quantum of damages claimed.

Step 1: Pre-Action Protocol and Letter of Claim

Before issuing a writ, the plaintiff’s solicitor should send a letter of claim to the defendant. The Hospital Authority has its own pre-action protocol for clinical negligence claims. The letter must set out the facts of the alleged negligence, the injuries suffered, and the estimated quantum of damages. The defendant has 21 days to acknowledge the letter and a further 90 days to investigate and respond. The protocol aims to encourage early settlement and avoid litigation. Failure to comply may result in adverse costs orders.

Step 2: Issuing the Writ and Statement of Claim

If settlement is not reached, the plaintiff issues a writ of summons in the District Court or the Court of First Instance. The writ must be accompanied by a statement of claim that pleads the material facts, including the specific acts of negligence, the injuries sustained, and the heads of damage claimed. The Limitation Ordinance (Cap. 347, Section 27(1)) provides that the writ must be issued within three years of the date the cause of action accrued, or within three years of the date of knowledge (if later). The court has a discretion to extend the limitation period under Section 30 of the same Ordinance, but only if it is equitable to do so and the plaintiff has a good reason for the delay.

Step 3: Discovery, Medical Examinations, and Trial

After the defence is filed, the court will give directions for discovery of documents, exchange of expert reports, and a pre-trial review. The plaintiff must submit to a medical examination by the defendant’s expert if requested. The court will list the case for trial. The District Court has a target of listing personal injury trials within 18 months of the writ being issued. The Court of First Instance has a longer timeline, typically 24 to 36 months.

Heads of Damage and Quantum of Compensation

The court awards damages to place the plaintiff in the same financial position as if the negligence had not occurred. Compensation is divided into general damages and special damages.

General Damages: Pain, Suffering, and Loss of Amenities

General damages compensate for the pain, suffering, and loss of amenity (PSLA) caused by the injury. The court refers to the “Judicial Studies Board Guidelines for Personal Injury Awards in Hong Kong” (published by the Hong Kong Judiciary, latest edition 2023). These guidelines provide brackets for various injuries. For example, severe brain damage with no awareness of the environment attracts damages of HK$1.5 million to HK$2.5 million. A moderate neck injury with ongoing symptoms may attract HK$150,000 to HK$300,000. The award is at the court’s discretion based on the specific facts.

Special Damages: Financial Losses and Expenses

Special damages cover quantifiable financial losses up to the date of trial. These include loss of earnings, medical expenses, travel costs to treatment, and the cost of care. The plaintiff must prove each item with documentary evidence. The Court of Final Appeal in Chan Pak Ting v The Hospital Authority (2018) 21 HKCFAR 1 confirmed that future loss of earnings is calculated by multiplying the annual loss by a multiplier derived from the “Chan Pak Ting Tables” (the official actuarial tables for Hong Kong). The multiplier is based on the plaintiff’s age and the discount rate, which is currently set at 2.5% per annum under the High Court Ordinance (Cap. 4, Section 12).

Provisional Damages and Structured Settlements

For cases where the plaintiff’s condition may deteriorate in the future, the court can award provisional damages under Section 56 of the High Court Ordinance. The plaintiff receives a lump sum now and retains the right to return to court for further damages if the specified risk materialises. Structured settlements, where the defendant pays periodic payments rather than a lump sum, are available under Section 56A of the same Ordinance. The Hospital Authority has entered into structured settlements in major brain injury cases to ensure the plaintiff’s long-term care costs are funded.

The Hospital Authority and the Public Hospital Context

The Hospital Authority (HA) is the dominant provider of public hospital services in Hong Kong. It operates 43 public hospitals and institutions and employs over 90,000 staff. Claims against the HA are governed by the same tort principles as claims against private hospitals, but there are practical differences.

The HA’s Statutory Protection and Indemnity

The Hospital Authority Ordinance (Cap. 113, Section 22) provides that the HA is not a servant or agent of the government. It is vicariously liable for the negligence of its employees. The HA self-insures for clinical negligence claims. It has a dedicated legal division that handles litigation. The HA’s annual report for 2023-2024 disclosed that it set aside HK$580 million for clinical negligence claims and potential settlements. Plaintiffs should be aware that the HA will defend claims vigorously, particularly on causation.

The Medico-Legal Reporting System

The HA operates a centralised medico-legal reporting system. When a writ is issued, the HA’s legal division instructs its own expert witnesses, usually senior consultants from other HA hospitals. The HA also maintains an internal incident reporting system. The report of an internal investigation is not automatically disclosable to the plaintiff. The Court of Appeal in Lee Kwok Hung v The Hospital Authority [2012] 5 HKLRD 1 held that internal investigation reports may be subject to litigation privilege if they were prepared for the dominant purpose of defending anticipated litigation. The plaintiff must apply to the court for specific discovery if the report is not voluntarily disclosed.

The Clinical Negligence and Patient Safety Committee

The HA established the Clinical Negligence and Patient Safety Committee in 2020 to review serious untoward events and recommend systemic improvements. The committee’s reports are not public, but they may be relevant in establishing a pattern of systemic negligence. In Wong Wai Man v The Hospital Authority (2023) 26 HKCFAR 84, the Court of Final Appeal allowed the plaintiff to rely on evidence of a previous similar incident at the same hospital to support a claim of systemic failure. The court held that such evidence was admissible if it was relevant to the issue of whether the defendant had taken reasonable care.

Practical Considerations and Common Pitfalls

A medical negligence claim is a high-risk, high-cost undertaking. The plaintiff must be prepared for a long and adversarial process.

Costs and Funding

The general rule in Hong Kong is that the losing party pays the winning party’s costs. The costs in a medical negligence trial can easily exceed HK$1 million. The District Court has a costs scale under Order 62 of the Rules of the District Court. The Court of First Instance has a higher scale. Legal aid is available from the Legal Aid Department for meritorious claims. The Legal Aid Department’s annual report for 2023 showed that it granted legal aid for 127 medical negligence claims, with a success rate of 43%. Private funding options include conditional fee agreements, which are not permitted in Hong Kong for litigation, but are permitted for arbitration. The Law Reform Commission of Hong Kong issued a report in 2023 recommending the introduction of conditional fee agreements for litigation, but no legislation has been enacted as of 2025.

The Limitation Period Trap

The three-year limitation period is the most common trap for litigants in person. The clock starts from the date of knowledge, not the date of the negligent act. The Court of Appeal in Cheung Man Yuk v The Hospital Authority [2016] 4 HKLRD 89 held that the date of knowledge is when the plaintiff knows that the injury is significant and attributable to the defendant’s conduct. A plaintiff who discovers years later that a retained surgical instrument caused chronic pain must issue the writ within three years of that discovery. A plaintiff who fails to do so is statute-barred.

The Importance of Preserving Evidence

The plaintiff must preserve all medical records, including private consultation notes, hospital discharge summaries, and imaging scans. The Hospital Authority retains medical records for seven years after the last attendance under the Hospital Authority Ordinance (Cap. 113, Section 27). The plaintiff should request copies of all records as soon as possible. The HA charges a fee for copying records under the Personal Data (Privacy) Ordinance (Cap. 486). The plaintiff should also obtain a contemporaneous medical report from an independent doctor to document the injuries before the medical records are amended or lost.

Key Takeaways

• The three-year limitation period under Cap. 347 starts from the date of knowledge, not the date of the negligent act — obtain legal advice immediately after discovering a potential injury.
• The District Court’s jurisdiction for personal injury claims was raised to HK$5 million in 2025, making it the appropriate forum for most medical negligence cases.
• Expert medical evidence is mandatory and must address both the standard of care (Bolam test) and causation (but-for test) on a balance of probabilities.
• The Hospital Authority self-insures and will defend claims on causation vigorously — internal investigation reports may be privileged and not automatically disclosable.
• Legal aid is available for meritorious claims with a 43% success rate, but costs can exceed HK$1 million if the claim fails.
