Coroner's concerns

AI summary

View full coroner's concerns

(1) Evidence was heard that 2 separate community pharmacists did not tell Lyn, (nor pass a message via her family who collected the tablets), that she must stop taking simvastatin during the course of the clarithromycin, required for her chest infection. The pharmacists did not know she was taking simvastatin. I am concerned that there is confusion and a variety of opinion amongst community pharmacists around the extent of the expectation or duty to perform ‘clinical checks’ to enable safe prescribing and what that practically entails.

(2) I am concerned that there is confusion amongst community pharmacists in Wales around the conflict between the expectation of safe prescribing/dispensing and patient confidentiality (when someone other than the patient collects the medication).

(3) I am concerned that community pharmacists in Wales only have very limited access to the Welsh Clinical Portal, where they can see relevant drug history and recent test results, which would enable them to properly and safely counsel patients to stop contraindicated drugs (here simvastatin with clarithromycin) but applicable more widely. I heard evidence that access to such information is available routinely in English pharmacies, but only in exceptional circumstances in Wales. I have no understanding of why that is the case.

(4) Here, had either community pharmacist had access to Lyn’s drug history, they would have noted the contraindication and either told Lyn, her representative or written on the pharmacy bag that she was to stop the simvastatin. This likely would have changed the outcome for Lyn.

Action Taken

The General Pharmaceutical Council inspected the pharmacies involved, finding them compliant, and reported that one pharmacy introduced prompt cards and raised awareness about clarithromycin/statin interactions. The GPhC itself will write to education bodies and publish a dedicated article to further raise awareness of these issues. (AI summary)

Investigation and inquest

On 31 January 2024 I commenced an investigation into the death of Lyn MAHER . The investigation concluded at the end of the inquest on 15/01/2026. The conclusion of the inquest was a narrative with the following cause of death:

1a hyperkalaemia 1b Statin-induced rhabdomyolysis following clarithromycin treatment for lower respiratory tract infection (contraindicated medication) 1c II Dilated Ischaemic Cardiomyopathy and acute on chronic kidney disease

Circumstances of the death

These were recorded as :- Lyn Maher was aged 79 when on 3rd January 2024 she was prescribed clarithromycin for a chest infection, and part of her usual medication regime was simvastatin for high cholesterol. There is a well-known contraindication between these drugs. Lyn was not told to stop taking her statin by either her GP, nor by a community pharmacist dispensing the drug. On 10th January, she was issued with a further prescription for the same drug and again she was not told to stop taking her statin by GP nor a different community pharmacist. On 15th January Lyn was admitted to the Royal Glamorgan Hospital with a variety of symptoms and remained in hospital thereafter. At no point was Lyn asked about whether she had co-ingested the drugs and her statin continued to be given. Lyn’s condition continued to deteriorate, and she became so weak she could not use her legs and could barely lift a spoon to her mouth. There was a missed diagnosis of rhabdomyolysis. There were missed opportunities by GP, community pharmacists and hospital clinicians to identify the co-ingestion of the contraindicated drugs. There were missed opportunities to stop the further administration of the statin at hospital. There were missed opportunities to test the creatinine kinase level which was undoubtedly rising. There was a missed diagnosis of rhabdomyolysis at hospital. Each of these factors more than minimally contributed to Lyn’s tragic death which occurred following a cardiac arrest due to hyperkalaemia on 23rd January 2024 The Inquest focused upon:-
- care and treatment from 3rd January 2024 until Lyn's death on 23rd January 2024
- Cause of death and the degree of contribution (if any) made by the concomitant ingestion of clarithromycin with simvastatin in the community, and the degree of contribution of other factors at hospital or generally
