A health board has been told to apologise for sending a patient with a suspected brain aneurysm home, telling her she had muscle pain, after which she collapsed and died.

The case was investigated by a public services watchdog which concluded NHS Tayside had failed to provide reasonable treatment.

A report by the Scottish Public Services Ombudsman (SPSO) said: "While we could not say that the woman's life would definitely have been saved if the relevant tests had been carried out, independent advice that we obtained said that it was probable that her condition was treatable."

The investigation was sparked after the woman's husband took his complaint to the SPSO following his wife's death.

Her GP referred her to Perth Royal Infirmary on January 7 last year with a suspected brain aneurysm after she reported sudden headache and neck pain.

After hospital assessment by a specialist trainee doctor and consultant physician, she was told the problem was likely muscular and discharged.

The woman, known only as Mrs C in the report, went back to her GP three times in the next 15 days before collapsing at home on January 24 with signs of acute bleeding on the brain.

Medical staff deemed further treatment inappropriate and the woman died two days later.

The SPSO sought an independent opinion on the woman's treatment from a consultant physician, who said she should have had a brain scan when she first attended hospital as well as a possible lumbar puncture to check for bleeding on the brain.

The watchdog found Mrs C's diagnosis of muscoskeletal neck pain "unreasonable" and asked the health board to apologise in writing to her husband for this and for failing to deal with his complaints in a "timely and professional manner".

NHS Tayside was also asked to provide evidence to ensure patients are monitored properly, that adults presenting with headaches are investigated in line with national guidelines and that discharge notes also comply with the same guidelines where required.
