Investigation and inquest
On 02.10.2009 I commenced an investigation into the death of Judith Lesley Marshall. The investigation concluded at the end of the inquest on 29.11.2013. The conclusion of the inquest was that Judith Lesley Marshall died from
1a Bronchopneumonia
1b The effects of Morphine
I recorded a Conclusion of Accidental Death.
Circumstances of the death
On 28.09.2009 Mrs Marshall, aged 72 years, was correctly prescribed, by her GP, 10mg of Morphine Sulphate bd (“Morphine Sulphate M/R Capsules 10mg BD SIXTY CAPSULES Quant. sixty (60) capsule”).
On the same day ████████ a pharmacist of Beecham’s Pharmacy, Derwent Practice, Norton, Malton, North Yorkshire dispensed 60 capsules of Morphine Sulphate at 60mg strength and not 10mg as prescribed.
The box of capsules carried numerous clear references to 60mg capsules.
████████ a trainee dispensing technician checked the medication dispensed by ████████ and confirmed it.
Mrs Marshall took the capsules as dispensed to her, twice a day as prescribed (taking 120mg of Morphine per day rather than 20mg). She was found by her husband dead in her bed on the morning of 30.09.2009.
Coroner’s concerns
(1) The Pharmacy’s Errors Book shows a number of drug errors (including higher or lower dose tablets and three wrong drugs) over a number of years. It is not clear whether and to what extent such internal records are policed.
(2) Despite a system of checking by a colleague it is apparent that there can be a mistake in dispensing medication which in this case was a controlled opiate drug. The consequences were fatal.
(3) It is not clear whether there is any software, obtainable from the Department of Health or elsewhere, that could read prescriptions and raise an alert if the label sought to be created or if the drug sought to be dispensed is wrong in identity or amount. This would be of particular significance when a high risk drug is dispensed or when a drug is dispensed in an unusual quantity, dosage or form.
(4) Mandatory procedures requiring a ‘read-back’ of the drug, its dosage, its frequency of administration and its total quantity may prevent such dispensing errors. In so far as the error in this case can be attributable to ‘Human Error’ it is concluded that the dispensing pharmacist focused on the figure of 60 and incorrectly attributed that to the dosage as well as to the number of capsules.
(5) A mandatory check, by a suitably qualified pharmacist or by a third party, at the end of the day after cashing up on the till, of records of each (prescription only) drug dispensed against the prescription would be a further precaution against a repetition of these circumstances.
(6) There is evidently no central database of all prescription errors so there can be no central monitoring of such errors and no means of determining trends or particular repeat errors.
