View full coroner's concerns
The general practitioner (GP) who prescribed Ms Murdock the combined contraceptive pill consulted the UK medical eligibility criteria (MEC) guidelines before she did so.

However, she then miscalculated Ms Murdock’s clot risk and she failed to calculate her cardiovascular risk.

She miscalculated the clot risk because she did not appreciate the difference between a family member with history of clot over the age of 45 years, and one under the age of 45 years. If she had calculated correctly, she would have recognised that Ms Murdock was at higher risk and she would have taken a different course of action.

She failed to calculate the cardiovascular risk because did not notice the relevant box in the MEC guidelines 11 page summary. If she had noticed the box, she would have recognised that Ms Murdock had multiple cardiovascular risk factors (obesity and smoking) and should only be prescribed Dianette following specialist consultation, if at all.

The GP suggested that an auto calculator of risk might be one way to assist in the avoidance of such errors in the future.

Dear Ms Hassell, Re: Lauren Louise Murdock

Thank you for your email dated 6th April 2022, which was sent to the Royal College of Obstetricians and Gynaecologists (RCOG). The RCOG passed to us the specific information and question to the FSRH. We are greatly saddened to hear of this tragic death and send our very sincere condolences to Ms Murdock’s family. We have reviewed the circumstances described in your report, and whilst we cannot comment on the clinical aspects with the limits of information provided, we note that the comments regarding use of the UK MEC. The FSRH strives to ensure that the UK MEC and all its clinical products such as guidelines, are both evidence based and accessible. In this instance, our reading of the information provided in your report is that the clinician treating Ms Murdock followed the UK MEC but did not notice information on page 11. We are commencing a planned update to the UK MEC in 2022, ahead of release in 2023, and we will use this feedback to consider how we can best format the content to maximise usability for clinicians. With regard to a suggestion for a ‘risk calculator’, the FSRH is currently in the preliminary stages of considering opportunities to create an APP to better support our highly valued guidelines and standards for professional use. Whilst it is not yet confirmed if and when an APP will be developed, which will be determined subject to viability and perceived benefits, we will as part of the early scoping explore whether a ‘risk calculator’ could be a part of this. Once again, our very sincere condolences to Ms Murdock’s family. We will use this incident to inform our guideline development work in the future

Position of reporter GP Staff Present at meeting

What happened? (Describe what actually happened in detail. Consider for instance, how it happened, where it happened, who was involved, and what the impact or potential impact was on the patient, the team, organisation and/or others) A 27yr old patient tragically died on 23/10/21. She had been started on the contraceptive pill 3 months prior. Post mortem revealed she died of Myocardial Infarction likely due to vasospasm from underlying hypertension. The patient was not known to have high blood pressure. The mother of the patient found a photo of a blood pressure reading taken at our surgery on the patient’s phone post mortem, it was dated 13/10/21 and the reading was 166/90. This reading was not entered in the records and not brought to the attention of any clinician.

Why did it happen? (Describe the main and underlying reasons – both positive and negative- contributing to why the event happened. Consider for instance the professionalism of the team, the lack of a system or a failing in a system, lack of knowledge or the complexity and uncertainty associated with the event) According to the records the patient did attend the surgery on 13/10/21 to see the HCA to collect a self-test smear pack. She had not been booked for a blood pressure check with the HCA.

The patient was started on the pill in July and she was asked to recheck her blood pressure in reception after a month. She may have come to check it for that reason in October. It is not clear why the blood pressure reading was not recorded - staff members present on the day could not recall seeing the patient or being given a blood pressure slip of a high reading but as it was 6 months ago it is difficult to recall. Staff members confirmed their usual practice is to record blood pressure readings into records and inform the doctor.

Therefore we cannot clarify why this happened - if the patient did not submit the reading to a member of staff or if she did submit it and it was overlooked.

What has been learned and what changes should be made (Demonstrate that reflection and learning that has taken place on an individual or team basis and that relevant team member have been involved in the analysis of the event. Consider, for instance, a lack of education and training; the need to follow systems and procedures, effective communication) Also outline the actions that should be implemented, how the event not reoccurring can be monitored)

We have learnt that more robust protocols need to be in place to prevent this from happening again. Reception staff are all already aware to record blood pressure readings in the patient records and inform the doctor of the reading on the same day. However, at busy times when there are a few patients in the waiting room and the phone is ringing or if a receptionist has been called away then it

Lathom Road Medical Centre

2a Lathom Road, East Ham, London E6 2DU is difficult to keep track of all patients coming to use the machine, we can try to safeguard against this by ensuring patients are given clear advice before they sit down to check their blood pressure.

A protocol has been created with clear guidance for staff – only adjustments to be made to it is for patient to wait 2 minutes before repeating the blood pressure if the 1st reading is raised and for staff to highlight to the doctor if the pulse is <60 or >100bpm. This will be placed in clear sight in the reception office.

A sign has been placed above the blood pressure machine guiding patients to hand the reading to the receptionist once checked.

Staff to remain vigilant of any patients using the machine to ensure patients do not leave without submitting a reading.

Further suggestions were made by staff at the meeting:
1. Re-site the machine closer to the reception desk so staff can keep a closer eye on the patients using the machine, the only problem with this is that it can’t be placed right next to the reception desk as it would raise confidentiality issues with the patients already queuing at the front desk. Reception staff suggested to place the machine on the opposite wall of the reception area where they would have better oversight of the patient – we shall try this.
2. Dr suggested we could place the machine in the far corridor away from the reception desk, however again there would be confidentiality issues as that corridor space is between 2 consulting rooms and patients could potentially be sitting by the bp machine for up to 15min therefore overhearing consults going on in the adjacent rooms. Except for this area there isn’t any other space on the ground floor for the machine to be placed whilst maintaining confidentiality and keeping fire exits clear at the same time.
3. Dr suggested we could have a list of specific criteria for which patients are allowed to check their blood pressure and not allow access to all patients. Reception staff were concerned they would have to face irate patients who are being turned away. Also as the machine was initially procured to help with opportunistic blood pressure screening, Dr felt it would not serve that purpose if we only allowed certain patients to use it.
4. suggested contacting the bp machine company to see if they operate any coin slot system whereby the patient needs to be given a coin to enter in the machine to be able to use it, thereby keeping a closer track on who is using it and returning readings – she will contact the company.
5. Dr suggested having a dedicated member of staff to supervise each patient checking their blood pressure throughout the process. mentioned that this is not always going to be possible as staff are already busy at the front desk and wouldn’t always have time to supervise every patient. We agreed that if staff members are free then they should try to stay with the patient though the monitoring process, failing that they should give the patient clear instructions to submit their readings to the front desk.

For the attention of HM Senior Coroner M E Hassell Response to prevention of future deaths report issued on 5th April 22 10th May 2022 Following the Inquest outcome the practice had already discussed the issue of the missing blood pressure reading in the practice meeting on 5th April 22. In that meeting staff were asked to clarify their current protocol on recording blood pressure readings submitted by patients using the machine in the reception area. They confirmed that they ask patients to give them the slip with the blood pressure reading from the monitor once they have checked it, they also confirmed that they record this reading in the records and inform the doctor by screen message. They also confirmed that if the blood pressure reading was high they would ask the patient to recheck their blood pressure. They would then submit these readings to the doctor. The practice manager also individually questioned the healthcare assistant and the reception staff that were working in reception on 13th of October 2021 if they had any recollection of this patient submitting this high blood pressure reading to them. The photo of the blood pressure reading submitted by the patient’s mother had a time stamp of 13.36. The patient attended for an appointment (to collect a self smear pack) with the Healthcare assistant at 14.35. (The time discrepancy has been found to be due to the clocks going forward and the blood pressure monitor needing to be manually updated). Unfortunately due to the length of time lapsed since the incident none of the staff members could recall seeing the patient, however they were all able to confirm that if they had been presented with a blood pressure reading as high as this they would have asked the patient to repeat their blood pressure and as per routine practice informed the doctor of the reading. As a result we are unable to clarify events of that day and how exactly this blood pressure reading was unfortunately missed. We have now created a sign and displayed it above the blood pressure monitor. It states to the patient to give their blood pressure reading to the receptionist. We have also created a protocol for blood pressure monitoring in the reception area for staff to follow, this clearly highlights the role of the receptionist in the monitoring process, guidelines for informing the doctor, abnormal values. The machine is calibrated annually to ensure accurate measurement of blood pressure. A significant event analysis meeting was also held on 20th April 2022. This included doctors, practice manager and reception staff. We discussed possible options to prevent this scenario recurring and have actioned the most feasible options. Wherever possible, the receptionist should remain with the patient and supervise the blood pressure monitoring, ensuring the reading is brought to the attention of the doctor. This of course may not be possible when short staffed or during busy periods, however staff to remain vigilant of any patients using the machine to ensure they do not leave before submitting a reading. We have also concluded to send an Accurx text message to any patient being started on combined hormonal contraceptives to recheck their blood pressure in a month, scheduling a reminder text message after a month prompting the patient to submit a reading. Whilst there is no faculty guidance on this, we believe learning from this incident could prevent future deaths.

Report sections

Investigation and inquest
On 9 October 2021, I commenced an investigation into the death of Lauren Louise Murdock aged 27 years. The investigation concluded at the end of the inquest on 29 March 2022. I made a narrative determination at inquest, which I attach.
Circumstances of the death
Lauren Murdock died of a myocardial infarction.

She was only 27 years old, but was at increased risk of this because she was obese, a smoker, had recently been prescribed the combined contraceptive pill, and then went on to develop hypertension. Also, at post mortem examination, she was found to have myocardial hypertrophy.
