A health board’s treatment of 14 breast cancer patients who died will be reviewed by an independent expert after bosses admitted hundreds of patients were given lower doses of chemotherapy.
NHS Tayside is changing its chemotherapy treatment after a watchdog report found patients were being given a lower dose of drugs than in the rest of Scotland.
Healthcare Improvement Scotland (HIS) found patients were not informed about the difference in treatment at the time.
The health board has since written to 304 patients who had chemotherapy for breast cancer from December 1 2016 to this month.
They have been offered an appointment with an oncologist.
NHS Tayside has now said 14 of these patients are dead and an independent expert will review the treatment these women were given.
A spokesman for the health board said: “As part of our response to the HIS report, NHS Tayside asked an independent expert to review the breast cancer chemotherapy treatment of 14 patients who have died.
“These patients received breast cancer chemotherapy during the time period December 1 2016 until March 31 2019.
“The findings will be shared with the families.”
Scottish Labour’s health spokeswoman Monica Lennon said: “The news that 14 women died after receiving lower than recommended dosages during chemotherapy treatment at NHS Tayside is deeply worrying.
“It is right that an independent expert will now investigate these deaths to give the families the answers that they need, but this should not have happened in the first place.
“The Health Secretary must ensure that all other clinical management guidelines are being met by NHS Tayside and all other health boards.”
Chief Medical Officer Dr Catherine Calderwood and Chief Pharmaceutical Officer Dr Rose Marie Parr ordered HIS to carry out an investigation after concerns were raised “about variations in treatment compared with other health boards in Scotland”.
The report warned of a possible “dysfunctional team environment” in NHS Tayside, with debate on the issue said to be “stifled”.
Other medical professionals within the board “expressed concern” about the lower dosage, the report said.
For patients being treated with a FEC-T regimen of chemotherapy, oncologists in NHS Grampian and NHS Highland recommended doses of 100mg/m2 of two of the drugs, Epirubicin and docetaxel, while in Tayside the recommended dosage was 75mg/m2 of Epirubicin and 80mg/m2 of docetaxel.
The report noted the practice in NHS Tayside was “also at variance with the rest of NHS Scotland”.
The “NHS Tayside breast oncology consultant team confirmed that patients were not informed of dosage or variation in dosage during the consent process”, the report said.
Doctors there had argued their practice was “in the best interests of patients in NHS Tayside”, saying that when higher doses of the drugs had been used in 2014-15, 51 of 98 patients had needed to have their dosage reduced.
The health board’s acting medical director Professor Peter Stonebridge apologised for any “distress” caused by the report.
He added: “We have taken assurance from the expert panel who has said that the risk of any negative impact to patients arising from the change in chemotherapy was very small.
“However, patient safety is always our number one priority and that is why we have taken action to rapidly change our approach to breast cancer chemotherapy, ensuring it is in line with practice across the rest of Scotland.”
A Scottish Government spokeswoman said: “Independent expert support is already involved. NHS Tayside have appointed an independent expert to review the treatment of the patients who died and will be sharing the findings with their families as a result of the HIS review.
“In addition, Professor Aileen Keel, chair of the Scottish Cancer Taskforce, is leading an expert group to fully consider all of the HIS recommendations, and how they can be best delivered.”
