Definition

What this concern includes

Includes failures in ambulance-service processes for defining, recording, calculating, aggregating or reporting response times, including omission of elapsed time after regrading and performance measures that conceal material response-delay spikes.

Not included

  • Excludes the underlying shortage of ambulances, crews or other response capacity where the measurement and reporting process is reliable.
  • Excludes ambulance call triage, dispatch, attendance and hospital handover failures when response-time measurement is not the deficient control.
  • Excludes general performance reporting unrelated to ambulance response times.
  • Excludes standards or prioritisation failures that do not also impair accurate measurement or reporting of response times.

    Report summary

    Kevin George Woods died on 17 January 2024 after suffering cardiac arrest following a prolonged ambulance delay when no Category 2 ambulance was available. The inquest found that he had an undiagnosed and possibly treatable heart condition and that the delay denied him potentially lifesaving treatment. The principal concerns were continuing ambulance and hospital handover delays, inadequate social care and community healthcare provision contributing to delayed discharges, and the absence of a single organisation responsible for managing the associated patient-safety risks.

    PFD Monitor interpretation

    Failure of average performance measures to reveal spikes in ambulance handover and response delays

    Wider context from the report

    “1) Continuing average handover delays (and therefore response delays) which create a risk of future deaths. The averages conceal spikes of delayed handover and ambulance response times which increase the risk of mortality. ”

    PFD Monitor interpretation

    Healthcare providers are responsible for identifying and mitigating risks within their services through their own patient-safety processes.

    Verbatim wording from the response

    “The responsibility for identifying and mitigating risks within healthcare services sits with the provider of those services. Each provider of NHS services will have their own internal processes and structures for the identification, examination, management and improvement of patient safety risks. The Care Quality Commission (CQC) is responsible for monitoring the quality and safety of the care provided by NHS Trusts through the regulation of the Trust’s regulated activities. The CQC carries out inspections and produces reports setting out their findings.”

    How this respondent position was interpreted

    PFD Monitor created a concise, searchable interpretation from the published response wording shown below.

    PFD Monitor interpretation

    The response clock for re-categorised calls starts at regrading because this timing was decided from a national perspective.

    Verbatim wording from the response

    “c) Is it fair that if a patient is regraded whilst awaiting an initial response, the total time from the initial call to the regrading is cancelled out?”
