Introduction

The case of T.M. v Health Service Executive (HSE) ([2023] IEHC 708) was adjudicated in the High Court of Ireland on December 1, 2023. The plaintiff, T.M., challenged the protocols governing the release and handling of CervicalCheck cytology slides, which are pivotal in clinical negligence litigation. The primary dispute centered around the existing Protocol for Release Of CervicalCheck Cytology Slides, particularly concerning the identification of experts, digital imaging specifications, and enforcement provisions. The defendant, HSE, alongside Medlab Pathology Limited as a third party, contested aspects of the protocol that they believed either complicated the process or infringed upon patient rights.

Summary of the Judgment

Justice Reynolds delivered a comprehensive ruling addressing four key issues related to the Protocol:

• Organisation of Return Courier: The court upheld the current practice where plaintiffs organize and fund the return of slides.
• Chain of Custody Record: The proposal to use a shared Google document was dismissed due to GDPR concerns.
• Imaging Requirements: It was mandated that whole slide imaging be the default, with digital images only released if physical slides are lost or damaged.
• Enforcement Provision: The proposed enforcement measures by the NSS were rejected as disproportionate and unnecessary.

The court emphasized maintaining the integrity and security of patient slides throughout the litigation process, ensuring that existing practices are both effective and compliant with privacy laws.

Analysis

Precedents Cited

The judgment referenced previous rulings, including the December 20, 2018 decision by Mr. Justice Cross, which established the current protocol practices. This precedent played a significant role in affirming the status quo, particularly regarding the handling and imaging of cytology slides. The court relied on established international guidelines which prioritize the use of physical slides as the most reliable evidence in cervical cytology litigation.

Legal Reasoning

Justice Reynolds meticulously evaluated each proposed amendment to the Protocol against the backdrop of security, integrity, and legal compliance. The court reasoned that increasing the number of parties involved in slide handling could heighten the risk of loss or damage, thus supporting the retention of the existing courier arrangement. Additionally, the dismissal of the shared Google document proposal was grounded in compliance with the General Data Protection Regulation (GDPR), emphasizing the importance of safeguarding sensitive patient information.

Regarding imaging, the court highlighted the potential for digital images to distort expert assessments compared to physical slides, upholding that whole slide imaging should be the default standard. The proposed enforcement provision was deemed excessive, as the revised Protocol already contained mechanisms to address non-compliance effectively.

Impact

This judgment reinforces the current practices surrounding the handling of CervicalCheck cytology slides, ensuring that they remain secure and are processed in a manner that upholds their evidentiary value. By rejecting the introduction of shared digital tracking systems and additional enforcement provisions, the court maintains a balance between streamlining the litigation process and protecting patient rights. Future cases will likely adhere to these established protocols, providing a clear framework for the management of cytology slides in legal settings.

The High Court's ruling in T.M. v HSE reaffirms the existing Protocol for Release Of CervicalCheck Cytology Slides, emphasizing the importance of maintaining secure and efficient processes in handling sensitive medical evidence within litigation. By upholding current practices and rejecting proposed amendments that could complicate procedures or infringe on privacy rights, the court ensures that the integrity of cytology slides is preserved.
