At an inquest into Patricia’s death earlier this month, it was heard she received Vitamin B12 injection into her right shoulder on October 17 last year.
The injections are usually given to treat vitamin B12 deficiency – as being low in the vitamin can cause anaemia.
A deficiency can also cause problems like extreme tiredness, pins and needles, mouth ulcers, vision problems, memory difficulties and even mild depression, the NHS says.
The day after her jab, Patricia became “unwell” and was taken to hospital where she was found to be suffering from a Strep A infection.
Strep A is a common type of bacteria that tends to cause mild infections.
In rare cases, however, a strep A infections can become serious – this is called invasive group A strep (iGAS).
Despite the best efforts of staff, Patricia’s condition continued to deteriorate and she sadly died on October 23.
A post-mortem found the “most likely source” of the invasive infection was the injection as it was likely “bacteria was present on the skin at the time” and pushed in deeper by the needle.
A jury found her death to have been caused by septicaemic shock and delivered a verdict of accidental death.
In a Prevention of Future Death report, Ms Sutton told of her concerns.
“The nurse who administered the injection gave evidence that she did not clean the skin prior to administering the injection,” she wrote.
“She did not do so because she was following both her training (she quoted from an NHS e-learning module on administering intramuscular injections) and national guidance in the form of a document titled ‘Immunisation Against Infectious Disease/The Green Book.”
She pointed out a section from it which says “if the skin is clean, no further cleaning is necessary. Only visibly dirty skin needs to be washed with soap and water”.

It goes onto say it is “not necessary” to disinfect the skin, with evidence that while alcohol wipes reduce bacteria, disinfecting ‘makes no difference to the incidence of bacterial complications of injection’.
Ms Sutton continued: “The evidence that I heard at the inquest included that alcohol wipes are relatively cheap and their use does not give rise to any significant risk.
“I note that the Green Book states that cleaning the skin with alcohol reduces the bacterial count.
“Common sense would seem to suggest that reducing the bacterial count would reduce the risk of bacteria being inadvertently introduced into the deeper tissues during an injection.
“Whilst it is noted that the Green Book also makes reference to there being evidence that disinfecting makes no difference to the incidence of bacterial complications, it is also noted that the literature quoted is now over 20 years old.”
She added: “In my opinion action should be taken to prevent future deaths and I believe your organisation has the power to take such action.”
Ms Sutton told the recipients of the report they are under a duty to respond by December 20.
