Investigation and inquest
On 9 October 2021, I commenced an investigation into the death of Lauren 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.
Coroner’s concerns
Lauren Murdock was a patient of your practice. Her general practitioner (GP) described in court several changes made in the Lathom Road practice following Ms Murdock’s death, but one issue remains outstanding.
At inquest, I heard that Lauren visited the practice on 13 October 2021 and saw a healthcare assistant. Her blood pressure was taken and was found to be significantly elevated at 166/90, with a heart rate of 98.
That blood pressure reading does not appear to have found its way to Ms Murdock’s medical record, and it was certainly not brought to Dr ████████ attention.
That is a significant omission. 13 October 2021 is the first time that Ms Murdock’s blood pressure was recorded as being elevated, and this was after the prescription of the combined contraceptive pill.
She died ten days later.
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.
