National comparative audit of red blood cell transfusion practice in hospices: Recommendations for palliative care practice

摘要

Background: Red blood cell transfusions are commonly used in palliative care to treat anaemia or symptoms caused by anaemia. In patients with advanced disease, there is little evidence of benefit to guide treatment decisions in the face of increased risk of harms. Aim: To determine national transfusion practice in hospices and compare this against National Institute for Health and Care Excellence and British Society of Haematology guidelines to develop recommendations to improve practice. Design and Setting: Prospective data collection on red blood cell transfusion practice in UK adult hospices over a 3-month census period. Results: A total of 121/210 (58%) hospices participated. A total of 465 transfusion episodes occurred in 83 hospices. Patients had a mean age of 71 years, and 96% had cancer. Mean pre-transfusion haemoglobin was 75 g/L (standard deviation = 11.15). Anaemia of chronic disease was the largest cause of anaemia (176; 38%); potentially amenable to alternative treatments. Haematinics were not checked in 70% of patients. Alternative treatments such as B12, folate and iron were rarely used. Despite transfusion-associated circulatory overload risk, 85% of patients were not weighed, and 84% had two or more units transfused. Only 83 (18%) patients had an improvement maintained at 30 days; 142 (31%) had 14 day improvement, and 50 (11%) had no improvement. A total of 150 patients (32%) were dead at 30 days. Conclusion: More rigorous investigation of anaemia, increased use of alternative therapies and more restrictive approach to red cell transfusions are recommended. Clinicians should discuss the limited benefit versus potentially higher risks with patients in hospice services to inform treatment decisions.
