The Clinical Safety of the Personally Controlled Electronic Health Record (PCEHR)

This submission comments on the consultations during PCEHR development, barriers to clinician and patient uptake and utility, and makes suggestions to accelerate adoption. The lens for these comments is patient safety.

The PCEHR like any healthcare technology may do good or harm. Correct information at a crucial moment may improve care. Misleading, missing or incorrect information may lead to mistakes and harm. There is clear evidence nationally and internationally that health IT can cause such harm [1-5].

To mitigate such risks, most industries adopt safety systems and processes at software design, build, implementation and operation. User trust that a system is safe enhances its adoption, and forces system design to be simple, user focused, and well tested.

The current PCEHR has multiple safety risks including:

  1. Using administrative data (e.g. PBS data and Prescribe/Dispense information) for clinical purposes (ascertaining current medications) – a use never intended;
  2. Using clinical documents (discharge summaries) instead of fine-grained patient data e.g. allergies. Ensuring data integrity is often not possible within documents (e.g. identifying contradicting, missing or out of date data);
  3. Together these create an electronic form of a hybrid record with no unitary view of the clinical ‘truth’. Hybrid records can lead to clinical error by impeding data search or by triggering incorrect decisions based on a partial view of the record [6];
  4. Shifting the onus for data integrity to a custodian GP avoids the PCEHR operator taking responsibility for data quality (a barrier to GP engagement and a risk because integrity requires sophisticated, often automated checking).
  5. No national process or standards to ensure that clinical software and updates (and indeed the PCEHR) are clinically safe.

The need for clinical safety to be managed within the PCEHR was fed into the PCEHR process formally [7], via internal NEHTA briefings, at public presentations at which PCEHR leadership were present and was clear from the academic literature. Indeed, a 2010 MJA editorial on the risks and benefits of likely PCEHR architectures highlighted recent evidence suggesting many approaches were problematic. It tongue-in-cheek suggested that perhaps GPs should ‘curate’ the record, only to then point out the risks with that approach [8].

Yet, at the beginning of 2012, no formal clinical safety governance arrangements existed for the PCEHR program. The notable exception was the Clinical Safety Unit within NEHTA, whose limited role was to examine the safety of standards as designed, but not as implemented. There was no process to ensure software connecting to the PCEHR was safe (in the sense that patients would not be harmed from the way information was entered, stored, retrieved or used), only that it interoperated technically. No ongoing safety incident monitoring or response function existed, beyond any internal processes the system operator might have had.

Concerns that insufficient attention was being paid to clinical safety prompted a 2012 MJA editorial on the need for national clinical safety governance both for the PCEHR as well as E-health more broadly [9]. In response, a clinical governance oversight committee was created within the Australian Commission on Safety and Quality in Health Care, (ACSQHC) to review PCEHR incidents monthly, but with no remit to look at clinical software that connects to the PCEHR. There is however no public record of how clinical incidents are determined, what incidents are reported, their risk levels or resulting harms, nor how they are made safe. A major lesson from patient safety is that open disclosure is essential to ensure patient and clinician trust in a system, and to maximize dissemination of lessons learned. This lack of transparency is likely a major barrier to uptake, especially given the sporadic media reports of errors in PCEHR data (such as incorrect medications) with the potential to lead to harm.

We recently reviewed governance arrangements for health IT safety internationally, and a wide variety of arrangements are possible from self-certification through to regulation [10]. The English NHS has a mature approach that ensures clinical software connecting to the national infrastructure complies with safety standards, closely monitors incidents and has a dedicated team to investigate and make safe any reports of near misses or actual harms.

Our recent awareness of large-scale events across national e-health systems – where potentially many thousands of patient records are affected at once – is another reason PCEHR and national e-health safety should be a priority. We recently completed, with the English NHS, an analysis of 850 of their incidents. 23% (191) of incidents were large-scale involving between 10 and 66,000 patients. Tracing all affected patients becomes difficult when dealing with a complex system composed of loosely interacting components, such as the PCEHR.

Recommendations:

  1. A whole of system safety audit and risk assessment of the PCEHR and feeder systems should be conducted, using all internal data available, and made public. The risks of using administrative data for clinical purposes and the hybrid record structure need immediate assessment.
  2. A strong safety case for continued use of administrative data needs to be made or it should be withdrawn from the PCEHR.
  3. We need a whole of system (not just PCEHR) approach to designing and testing software (and updates) that are certifiably safe, to actively monitor for harm events, and a response function to investigate and make safe root causes of any event. Without this it is not possible for example to certify that a GP desktop system that interoperates with the PCEHR is built and operated safely when it uploads or downloads from the PCEHR.
  4. Existing PCEHR clinical safety governance functions need to be brought together in one place. The nature, size, structure, and degree to which this function is legislated to mandate safety is a discussion that must be had. Such bodies exist in other industries e.g. the civil aviation safety authority (CASA). ACSQHC is a possible home for this but would need to substantially change its mandate, resourcing, remit, and skill set.
  5. Reports of incidents and their remedies need to be made public in the same way that aviation incidents are reported. This will build trust amongst the public and clinicians, contribute to safer practice and design, and mitigate negative press when incidents invariable become public.
