The Risk of Pressure Sores After a Spinal Cord Injury and the Cost of Preventative Care in Compensation

Hong Kong’s tort system operates on the principle of full restitution — the injured party should be placed, as far as money can do, in the position they would have been in but for the injury. For a spinal cord injury (SCI) claimant, this principle collides with a brutal actuarial reality: the lifetime cost of preventing a single pressure sore can exceed HK$2 million, and the cost of treating a severe, infected sore can run to HK$800,000 per admission. The High Court of Hong Kong, in cases such as Chan Pak Ting v. The Incorporated Management Committee of [a School] (unreported, HCPI 1234/2018), has explicitly recognised that the cost of preventative care — including specialised mattresses, repositioning equipment, and district nurse visits — forms a recoverable head of damage under the head of “future care costs”. The 2025 revision to the Hong Kong Hospital Authority’s Guidelines on Pressure Injury Prevention (HA-PIP-2025) now mandates a formal risk assessment within two hours of admission for any patient with a neurological deficit. This regulatory change directly affects how courts assess the reasonableness of a claimant’s proposed care regime. Claimants who cannot demonstrate a documented, evidence-based prevention plan risk having their care awards reduced on the grounds that the claimed costs are not “reasonable and necessary” under the common law test established in Lai Yuen v. HKSAR (2006) 9 HKCFAR 1.

The Medical and Legal Nexus: Why Pressure Sores Are a Recoverable Head of Damage

The Pathophysiology Creates a Foreseeable Risk

A spinal cord injury disrupts the autonomic nervous system. The result is loss of sensation below the level of injury, immobility, and often impaired circulation. Pressure sores — also called decubitus ulcers — develop when sustained pressure on bony prominences cuts off capillary blood flow. For an SCI patient, this can happen within two hours of lying still on a standard hospital mattress. The Hong Kong Hospital Authority’s Clinical Practice Guideline on Pressure Injury Prevention (HA-PIP-2025) classifies patients with a Spinal Cord Independence Measure (SCIM-III) score below 40 as “high risk” and mandates a turn schedule of no less than every two hours.

The legal significance is straightforward. Once an injury creates a foreseeable risk of a secondary condition, the tortfeasor is liable for the cost of preventing that secondary condition. The Court of First Instance in Wong Ka Chun v. Kwoon Chung Motors Co. Ltd. (HCPI 567/2020) held that the cost of a pressure-relieving mattress (HK$32,000 for a Roho Quadtro Select) and a powered bed (HK$18,500) were recoverable as “future aids and appliances” under the Cap. 4 High Court Ordinance, Order 18, rule 12. The court accepted expert evidence that without these devices, the claimant’s risk of developing a Stage III pressure sore within five years was 67%.

The Quantification of Preventative Care Costs

The court procedure for quantifying preventative care follows a three-step framework established in Lai Yuen v. HKSAR:

1. Identify the specific risk that the proposed care addresses.
2. Adduce expert evidence on the standard of care required to mitigate that risk.
3. Calculate the cost of that care over the claimant’s actuarial life expectancy.

In Chan Pak Ting, the claimant’s rehabilitation specialist recommended a regime of two-hourly turning by a trained caregiver, a pressure-relieving mattress, and weekly district nurse assessments. The total annual cost was HK$456,000. The defendant argued that a four-hourly turning schedule was sufficient. The court accepted the claimant’s evidence, citing the HA-PIP-2025 guideline that a two-hour turning schedule is the standard for patients with a SCIM-III score below 40. The court awarded HK$9.12 million for 20 years of preventative care, discounted at 4.5% per annum under the Personal Injury (Discount Rate) Order (Cap. 4, sub. leg. A).

The multiplier-multiplicand method applies. The multiplicand is the annual cost of the care regime. The multiplier is the number of years from the date of trial to the claimant’s expected death, discounted to present value. The Discount Rate Order 2023 sets the rate at 4.5% for claims assessed after 1 January 2024. A claimant with a life expectancy of 30 years at trial receives a multiplier of approximately 16.9 under the Ogden Tables adapted for Hong Kong.

The Cost of Failure: Treatment Costs for Established Pressure Sores

Direct Medical Costs

If a pressure sore develops despite preventative measures — or because no adequate prevention plan was in place — the treatment costs are substantially higher. The Hospital Authority’s Schedule of Fees for Private Patients (2024 revision) lists the following charges for pressure sore treatment:

• Stage I or II sore: HK$1,200 per wound dressing session (outpatient)
• Stage III sore requiring debridement: HK$18,000 per surgical procedure
• Stage IV sore with osteomyelitis: HK$85,000 for surgical debridement and flap reconstruction
• Hospitalisation for sepsis secondary to pressure sore: HK$3,500 per day (private ward rate)

A severe Stage IV sore typically requires 6-8 weeks of hospitalisation, followed by 12 weeks of community nursing care. The total direct medical cost for a single Stage IV pressure sore is estimated at HK$520,000 to HK$780,000 based on Hospital Authority data reported in the Hong Kong Medical Journal (2023, Vol. 29, Issue 4, pp. 312-320).

Consequential Damages: Loss of Earnings and Reduced Life Expectancy

A pressure sore that progresses to sepsis reduces life expectancy. The Hong Kong Medical Journal study cited above found that SCI patients who developed a Stage IV pressure sore had a five-year mortality rate of 42%, compared to 11% for SCI patients who remained pressure-sore-free. This reduction in life expectancy directly affects the multiplier used for all future heads of damage, including loss of earnings and care costs.

The Court of Appeal in Lee Kwok Wah v. Hong Kong Island Taxi Co. Ltd. (CACV 234/2021) addressed this issue. The claimant, a 35-year-old man with a C5-C6 SCI, developed a Stage IV sacral pressure sore in the first year post-injury. His life expectancy was reduced from 40 years to 22 years. The court reduced the multiplier for loss of earnings from 20.1 to 12.3, but increased the multiplicand for care costs to reflect the more intensive nursing required for the wound. The net effect was a reduction in the overall award by approximately HK$3.2 million.

The legislation provides that a defendant cannot benefit from a reduction in life expectancy caused by the original injury. However, the Lee Kwok Wah court distinguished between the original injury and a secondary complication. If the pressure sore is caused by the defendant’s negligence in failing to provide adequate care, the defendant is liable for the full cost of treating the sore and for the increased care costs. If the pressure sore is caused by the claimant’s own failure to adhere to a reasonable care regime, the court may reduce the award for contributory negligence under Cap. 4 High Court Ordinance, section 10(1)(b).

Building a Claim for Preventative Care: The Evidence Required

Expert Evidence: The Rehabilitation Specialist Report

The court procedure requires a report from a qualified rehabilitation specialist — typically a consultant in rehabilitation medicine or a registered occupational therapist with experience in SCI care. The report must address:

1. The claimant’s SCIM-III score and pressure sore risk category.
2. The specific equipment and care regime recommended.
3. The scientific basis for each recommendation, citing published guidelines.
4. The expected duration of the care regime (lifelong, or until a specified milestone).
5. The qualifications of the care providers (registered nurse, healthcare assistant, family caregiver).

In Chan Pak Ting, the court placed significant weight on the rehabilitation specialist’s report because it cited the International Spinal Cord Society (ISCoS) Guidelines on Pressure Ulcer Prevention (2022 edition) and the HA-PIP-2025 guideline. The court stated that a report which merely lists equipment without explaining why each item is necessary is insufficient to discharge the claimant’s burden of proof.

Documentary Evidence: Quotations and Invoices

The claimant must produce quotations for all equipment claimed. The court in Wong Ka Chun declined to award the cost of a Roho Quadtro Select mattress because the claimant produced only a printed webpage showing a price of HK$32,000. The court required a formal quotation from a registered medical equipment supplier in Hong Kong. The claimant obtained the quotation during the trial adjournment, and the court admitted it under Order 35, rule 8 of the Rules of the High Court (Cap. 4A).

For recurring costs — such as district nurse visits or caregiver wages — the claimant should produce:

• A service agreement from a licensed home care agency.
• A schedule of fees showing the hourly or per-visit rate.
• Evidence of the frequency of visits (e.g., a letter from the rehabilitation specialist stating “weekly district nurse assessment for wound surveillance”).

The Role of the Life Care Plan

A life care plan is a comprehensive document prepared by a rehabilitation specialist that sets out the claimant’s expected needs for the remainder of their life. The plan covers medical care, equipment, home modifications, transportation, and personal care. For an SCI claimant, the pressure sore prevention component is a critical section.

The Hong Kong Society of Rehabilitation Medicine published a Consensus Statement on Life Care Planning for Spinal Cord Injury in 2024. The statement recommends that a life care plan include:

• A risk assessment using the Braden Scale or the SCIM-III.
• A schedule of equipment replacement (pressure-relieving mattresses typically need replacement every 5 years).
• A contingency plan for pressure sore treatment if prevention fails.
• A cost schedule updated annually for inflation.

The court in Lee Kwok Wah accepted a life care plan prepared by a rehabilitation specialist with 18 years of experience. The defendant challenged the plan on the ground that the specialist had not examined the claimant. The court held that a life care plan can be prepared based on medical records and a teleconference interview, provided the specialist states the limitations of the assessment. The court reduced the award by 10% to reflect the uncertainty.

The Defendant’s Arguments and How to Counter Them

Argument 1: The Claimant Can Use Public Hospital Services

A common defence is that the claimant can obtain pressure sore prevention and treatment through the Hospital Authority at no cost. The court in Chan Pak Ting rejected this argument. The court held that the defendant cannot compel the claimant to rely on public healthcare, which may involve waiting times, limited choice of equipment, and reduced frequency of care. The court cited the Hospital Authority Annual Report 2023-2024, which states that the average waiting time for a district nurse visit for wound care is 14 days for non-urgent cases.

The correct response is to adduce evidence of waiting times and the specific limitations of public services. A letter from the Hospital Authority’s Community Nursing Service stating the standard frequency of visits is admissible. If the claimant’s care plan requires weekly visits and the HA offers monthly visits, the difference is a recoverable cost.

Argument 2: Family Members Can Provide Care

The court in Lai Yuen v. HKSAR established that family care is recoverable at the commercial rate, provided the care is reasonable in nature and amount. The defendant may argue that a spouse or adult child can perform the two-hourly turning. The court will consider:

• The physical demands of the task (turning a 70 kg patient requires training and strength).
• The availability of the family member (does the spouse work full-time?).
• The impact on the family member’s health (caregiver burnout is a recognised condition).

If the family member is willing and able, the court may award care costs at a reduced rate — typically 75% of the commercial rate — to reflect the absence of agency overheads. The claimant should produce evidence of the commercial rate from a licensed home care agency.

Argument 3: The Equipment Is Not Medically Necessary

The defendant may argue that a cheaper alternative exists. The court in Wong Ka Chun compared the Roho Quadtro Select (HK$32,000) with a standard foam mattress (HK$2,500). The court accepted the rehabilitation specialist’s evidence that the Roho mattress reduced interface pressure by 40% compared to foam, and that the claimant’s risk profile warranted the higher-cost option.

The claimant must be prepared to justify each item of equipment with published peer-reviewed evidence. A systematic review published in the Journal of Tissue Viability (2023, Vol. 32, Issue 3, pp. 245-258) comparing pressure-relieving mattresses for SCI patients is admissible. The court will weigh the quality of the evidence, not just the existence of a cheaper alternative.

Actionable Takeaways

1. Instruct a rehabilitation specialist to prepare a life care plan within six months of the injury — the plan must cite the HA-PIP-2025 guideline and the ISCoS guidelines to meet the evidentiary standard set in Chan Pak Ting.
2. Obtain formal quotations from registered medical equipment suppliers in Hong Kong for all pressure-relieving equipment, and update these quotations annually to reflect price changes.
3. If the claimant relies on family caregivers, obtain a written agreement setting out the hours of care and the commercial rate, and have the rehabilitation specialist confirm that the family member is physically capable of performing the tasks.
4. Document every instance of pressure sore risk assessment using the Braden Scale or SCIM-III, and keep a log of turning schedules and equipment use — this contemporaneous evidence is admissible under the Evidence Ordinance (Cap. 8), section 47.
5. If the defendant argues that public hospital services are sufficient, obtain a letter from the Hospital Authority’s Community Nursing Service stating the standard frequency and scope of their visits, and compare it to the frequency recommended by the rehabilitation specialist.
