Coroner's Concerns (AI summary)
There is a critical gap in ambulance response categories, as some patients requiring an immediate response to prevent life-threatening deterioration do not meet Category 1 criteria.
View full coroner's concerns
In respect of the National Ambulance Response Programme, I understand from the evidence that:
- Category 1 is an immediate response to a life-threatening condition. It should only be used for a patient who requires resuscitation or emergency intervention from the ambulance service, for example, a patient who is in cardiac or respiratory arrest. Mortality rates are high where a difference of one minute in response time is likely to affect outcome and there is evidence to support the fastest response. The national standard is for 90% of Category 1 patients to have received a response within 15 minutes; and for the overall average response time to be within 7 minutes.
- Category 2 is for serious conditions, for example stroke or chest pain, that may require rapid assessment and/or urgent transport. Mortality rates are lower; a difference of an extra 15 minutes’ response time is unlikely to affect outcome and there is evidence to support an early dispatch. The national standard is for 90% of patients to have received This document was classified as: OFFICIAL a response within 40 minutes; and for the overall average response time to be within 18 minutes. My concern is that there are circumstances in which a patient is not, at the time a 999 call is made to request an Ambulance, in a condition such as cardiac or respiratory arrest; but where an immediate response is still required on the basis that delay in ambulance attendance could pose a risk to their life. That is, I am concerned that there is a category of patients who do not meet the criteria for a category 1 response, but who do nonetheless require an immediate response, and that there is, therefore, a “gap” between categories 1 and 2. This includes for patients who are alone at the time of calling 999 and who are therefore unable to update the Ambulance Service should they progress to cardiac or respiratory arrest.

Dear Coroner, Re: Regulation 28 Report to Prevent Future Deaths – Peter Coates who died on 14th March 2019
Thank you for your Report to Prevent Future Deaths (hereafter “Report”) dated 23rd March 2026 concerning the death of Peter Coates on 14th March 2019. In advance of responding to the specific concerns raised in your Report, I would like to express my deep condolences to Peter’s family and loved ones. NHS England is keen to assure the family and yourself that the concerns raised about Peter’s care have been listened to and reflected upon.
Your Report raises concern that there may be circumstances when a patient requires an immediate ambulance response but they are not in cardiac or respiratory distress and therefore these patients do not meet the criteria for a Category 1 response. You are concerned that there is a “gap” for patients that fall between Category 1 and 2 responses.
In 2017, following the largest clinical ambulance trials in the world, NHS England implemented new ambulance standards across the country. This was to ensure that the sickest patients get the fastest response and that all patients get the right response first time. NHS Ambulance Services are required to process 999 calls through an approved triage system. There are currently two long established systems approved in England for primary 999 triage; NHS Pathways and Medical Priority Dispatch System (MPDS). The systems are used to prioritise 999 calls received into Ambulance Services’ Emergency Operations Centres (EOCs). The primary purpose of triage is to quickly identify priority symptoms (e.g. unconsciousness, difficulty breathing, chest pain) and to assign an appropriate response priority. The outcome (disposition) reached based on the information provided by the caller is mapped to one of the five national categories (Categories 1 –
5) set out within the NHS Constitution and Ambulance Service 999 contracts. The development of triage question sets and instructions lies within the remit of the triage system provider. National Medical Director NHS England Wellington House 133-155 Waterloo Road London SE1 8UG

The current ambulance categorisations ensure that all emergency responses are prioritised appropriately; Category 1 covers the most urgent, life-threatening cases, while Category 2 addresses emergency but less critical incidents. These two categories are sufficient for effective triage and timely intervention for life threatening and emergency conditions. In cases where there is risk of a patient’s condition deteriorating whilst waiting for an ambulance to arrive, the call handler could stay on the line with the patient; this is an operational decision to be made by each ambulance service. Moreover, the provision of instructions or actions to be taken in the case of worsening patients is a standard component of call exit scripts, whereby patients are advised that if their condition worsens, they should call 999 back. This provides an opportunity for a call to be re- triaged and potentially upgraded to a higher category response if this is clinically indicated. In cases where a patient is dependent on a piece of medical equipment e.g. continuous BiPAP, the accountable clinician who is responsible for overall care of the patient (e.g. their GP or hospital consultant) may wish to flag the patient to the local ambulance service to enable the ambulance service to make a note on the patient’s details within the services’ records system. This can be recorded in the urgent care plan or summary care record dependent on the local service. Then, if the patient / carer contacts 999 and is presenting with a problem relating to this equipment / medical device they can be managed rapidly to receive the appropriate care.
I would also like to provide further assurances on the national NHS England work taking place around the Reports to Prevent Future Deaths. All reports received are discussed by the Regulation 28 Working Group, comprising Regional Medical Directors, and other clinical and quality colleagues from across the regions. This ensures that key learnings and insights around events, such as the sad death of Peter, are shared across the NHS at both a national and regional level and helps us to pay close attention to any emerging trends that may require further review and action.
Thank you for bringing these important patient safety issues to my attention and please do not hesitate to contact me should you need any further information.

Investigation and Inquest
On 15 March 2019 an investigation was commenced into the death of Peter COATES, aged 62 (born 13.04.1956). The investigation concluded at the end of the inquest on 20.03.2026. The conclusion of the inquest was a narrative conclusion as follows: “Peter died due to complications of Very Severe Chronic Obstructive Pulmonary Disease, with his death contributed to by the consequences of Obesity. Peter would not have died when he did, in the absence of an unplanned electrical power supply failure to his home address which caused his mains operated, bilevel positive airway pressure (BiPAP) and oxygen concentrator equipment to stop working.” I found Peter’s medical cause of death to be: 1a) Complications of Very Severe Chronic Obstructive Pulmonary Disease.
2) Obesity.
2) Obesity.
Circumstances of the Death
Peter Coates’ past medical history included Very Severe Chronic Obstructive Pulmonary Disease (“COPD”) and Obesity. Peter sadly died at his home address of 42 Boulby Road, Redcar on 14.03.2019. Due to the severity of his COPD, Peter was reliant on at home, mains operated, clinical equipment, namely a bilevel positive airway pressure (BiPAP) machine and an oxygen concentrator. At 03:57 on 14.03.2019, Peter’s home address lost electrical power due to an unplanned electrical power supply failure. At 04:01, Peter contacted 999 and spoke to a Health Advisor at the North East Ambulance Service NHS Foundation Trust. During this telephone call, information provided by Peter included that: he had COPD and used an oxygen machine but there had been a power cut, he was struggling to breathe, could not reach his portable oxygen cylinders, and was home alone. Peter also confirmed the approximate location of, and the code for, a key safe at his home address. The key safe code was included in the crew notes subsequently made available to the attending Paramedics; however, the approximate key safe location was not included in the crew notes. This document was classified as: OFFICIAL A category 2 emergency ambulance response was assigned to Peter. I heard that the national Ambulance Response Programme requires, for category 2 responses, an overall average response time within 18 minutes, and a response to 90% of category 2 calls within 40 minutes. An ambulance crew was allocated to Peter at 04:04. That ambulance crew had an expected journey time to Peter’s home address of 1 minute and 37 seconds. That ambulance crew was, however, unable to depart from the ambulance station, due to the power failure meaning the electrically powered station gates would not open, with relevant staff being unaware of how to manually open the station gates. At 04:15, the category 2 emergency ambulance response to Peter was reallocated to a different ambulance crew. That ambulance crew, whilst travelling to Peter’s home address, stopped at a petrol garage to refuel at 04:23, leaving the petrol garage at 04:27, and arriving at Peter’s home address at 04:38. Following their arrival, the attending ambulance crew were initially unable to find the key safe and/or gain access to Peter’s property. Having located the key safe, the ambulance crew gained entry to Peter’s property at or around 04:48 and shortly thereafter found Peter to sadly be deceased on his bed. It was noted by the attending ambulance crew that Peter had obtained a portable oxygen cylinder, which was not dependent on a mains electricity supply, and which was delivering oxygen via a nasal cannula. The electrical power supply to Peter’s property was restored at 05:14 on 14.03.2019. Peter died due to complications of Very Severe COPD, with his death contributed to by the consequences of Obesity. Peter would not have died when he did, in the absence of the unplanned electrical power supply failure. Peter’s death was possibly contributed to by delays in the arrival of the ambulance crew to him. I heard evidence at the inquest hearing that a category 1 emergency ambulance response could not have been generated for Peter, as he was breathing and conscious at the time of the 04:01 999 telephone call.
