| All patients using a dialysis machine - which cleans their blood because their kidneys can no longer do this - need to have a special strengthened blood vessel made for them, to connect to the machine. Usually this is a fistula, made by joining an artery with a vein, but for a small number of patients whose veins are fragile, a piece of plastic tubing called an arterio-venous graft is used instead. | All patients using a dialysis machine - which cleans their blood because their kidneys can no longer do this - need to have a special strengthened blood vessel made for them, to connect to the machine.

| Buttonholing, on the other hand, involves putting needles into the same hole each time. This is safe for those with fistulas, but for those using grafts, it "has always been avoided... due to the risk of infection and graft degradation", according to the UK Kidney Association guidelines which are used throughout the NHS.

| Her death certificate gave the cause of death as a stroke, end-stage renal failure and Covid-19. Her husband repeatedly asked the hospital to investigate why her blood pressure had suddenly increased in the months before her death. He says he never got an answer on this, and both he and Dr Macanovic now wonder if it was linked in some way to the complications she had been experiencing with her kidney dialysis. | Her death certificate gave the cause of death as a stroke, end-stage renal failure and Covid-19.

| Dr Macanovic's audit found that Mrs Kelsey's complication rate during buttonholing was almost six times higher than it had been previously, and that in the three years after she started buttonholing, Mrs Kelsey had had at least 18 interventions related to problems with her graft. In the three previous years, when she had been using the standard rope-laddering technique, she had needed just one intervention. | Dr Macanovic's audit found that Mrs Kelsey's complication rate during buttonholing was almost six times higher than it had been previously, and that in the three years after she started buttonholing, Mrs Kelsey had had at least 18 interventions related to problems with her graft.

| Dr Macanovic says she drew her colleagues' attention to several sets of guidelines which outlined the dangers of buttonholing, wrote to the grafts' manufacturers who confirmed that "the buttonhole technique… cannot be used", and reported her colleagues' actions to regulators - the Care Quality Commission (CQC) and the General Medical Council (GMC). | Dr Macanovic says she drew her colleagues' attention to several sets of guidelines which outlined the dangers of buttonholing, wrote to the grafts' manufacturers who confirmed that "the buttonhole technique… cannot be used", and reported her colleagues' actions to regulators - the Care Quality Commission (CQC) and the General Medical Council (GMC). |
