THE widow of a man who died after an NHS blunder meant a bowel cancer diagnosis was delayed by more than six months has accused a hospital of attempting to cover up a catalogue of errors.

The patient, who was 71 when he died, survived for just six months after he was finally diagnosed with terminal cancer in October 2011.

He had initially been referred for urgent tests at Hairmyres Hospital in East Kilbride the previous March, but did not receive an appointment and was kicked off a waiting list.

It was only when he returned to his GP in August that the tests were arranged. They were eventually carried out in September and October.

NHS Lanarkshire initially claimed that the father-of-four, a former scaffolder, had phoned up to cancel his initial appointment. However, his wife revealed that he was unable to speak on the phone as the result of a major stroke.

She maintains that the hospital did not write to her husband to offer an appointment.

Scottish Public Services Ombudsman Jim Martin, who investigated the case, said there was no clear evidence of when the two letters which NHS Lanarkshire should have issued had been sent out and that the claim an appointment had been cancelled by phone was incorrect.

NHS Lanarkshire admitted it failed to notify the patient's GP that he had been removed from the waiting list, as it should have done.

The widow, who has asked to remain anonymous, said she is still struggling to come to terms with the errors the hospital, in her home town, committed.

"I don't even like passing by the hospital," she said. "It all brings it all back. If they had just sent a letter apologising... but no-one seemed to care. They have lied and been covering up for each other.

"I do think the outcome might have been different if we'd got the diagnosis earlier, I feel there is something that could have been done."

The Ombudsman also criticised the health board for the manner in which it delayed a sigmoidoscopy, a procedure in which the colon is examined.

The patient attended the hospital for the appointment but was kept waiting for four hours in considerable pain before being told the appointment had been cancelled with no explanation. It went ahead a week later.

Mr Martin said: "I am critical that the board's original response to [the] complaint provided incorrect information about [the patient] calling to cancel an appointment when there was no evidence of this. This must have added to distress at such a difficult time. I am also critical of the board's lack of audit trail to show when the two appointment letters were issued.

"The board have acknowledged that they failed to inform the GP that [the patient] was removed from the waiting list on 27 April 2011 in accordance with their appointment protocol. I consider this caused an unreasonable de lay of around six months in bowel symptoms being investigated and cancer diagnosis being known."

An expert advisor to the Ombudsman said it was unlikely that the patient's prognosis would have been better had he been diagnosed six months earlier. However, he said the patient and his family would have had longer to come to terms with the condition.

As a result of the Ombudsman's recommendations, NHS Lanarkshire is to investigate whether its rules have been followed in other cases where patients have been removed from waiting lists.

A spokeswoman for the health board said: "We regret any instance where we have failed to maintain the highest standard. We have fully accepted the recommendations contained within the Ombudsman's report and will be writing to the complainant with our sincere apologies. We will also develop an action plan to address the areas highlighted within the report and ensure lessons learned are shared across NHS Lanarkshire".
