Distribution by transfusion burden
Share of transfused patients
Burden tiers — low / mid / high
Low = 1–10 units, Mid = 11–40, High = 41+. Most well-run units are dominated by the Low tier; a large Mid tier is the group to target with an anaemia QI project.
Automatic analysis
Total patients ever transfused: 179. Estimated transfusion events: ~1646 (mean 9.2 per patient).
Suggested action: Use this page together with the "Transfusion Timing" page to understand both the volume and the timing of transfusions.
Only 3.9% of transfused patients (7) have a heavy transfusion burden (41+ units).
Suggested action: Maintain current anaemia protocols; continue monitoring for drift.
79.9% of transfused patients (143) received 10 or fewer units in total — the cohort is dominated by low-burden patients.
Suggested action: This is the expected pattern in a well-managed unit. Focus audit resources on the 7 high-burden patients instead of the whole cohort.
Largest single group: 1-5 units (102 patients, 57%).
Suggested action: Match dietitian, pharmacist and anaemia-nurse effort to this group's actual burden tier.
The distribution has a long tail: a small number of patients consume a disproportionate share of blood-bank resources.
Suggested action: Before planning the anaemia budget, quantify red-cell units consumed by the top 5% of patients. This is usually the single most actionable number for cost and clinical improvement.
Each transfused unit raises allosensitisation risk and reduces future transplant chances. In young or potentially transplantable patients, transfusion is a decision with long-term consequences, not a neutral intervention.
Suggested action: Ensure every transfusion in a transplant-eligible patient is documented with indication, alternatives considered, and transplant-team awareness.
What this page measures
Every patient is grouped by the total number of transfusion records they have in mi2. The x-axis is how many transfusion events that patient has had over their dialysis history. This turns the transfusion register from an event log into a patient-burden map — which is the form you need for both clinical targeting and budget planning.
Why it matters
- Small high-burden subgroup consumes most of the blood bank and carries the highest allosensitisation risk.
- Mid-burden group is the one most likely to be moved down a tier with better iron, ESA and inflammation management.
- Distribution shape tells you whether anaemia is a unit-wide problem (broad distribution) or a small-group problem (long tail).
- Budget planning — the top 5% of transfused patients often account for 40–60% of red-cell units consumed.
- Transplant protection — young, potentially transplantable patients should ideally receive zero transfusions; every unit reduces future matching chances.
What drives a high transfusion burden
- ESA hyporesponse (chronic inflammation, infection, malignancy)
- Iron deficiency not corrected (low ferritin or low TSAT)
- Chronic blood loss (access, GI, menses, surgery)
- Severe hyperparathyroidism / bone-marrow fibrosis
- Malnutrition and low albumin
- Undiagnosed haemoglobinopathy or marrow disease
- Repeated access failure and catheter-related bleeding
Why the low-tier majority is not always reassuring
- A single transfusion in a transplant-eligible patient already causes allosensitisation.
- Each transfusion triggers iron overload cumulatively across the cohort.
- Even "1–5 units" in a patient with a young age or short vintage signals a systemic problem worth investigating.
- The goal is not just fewer high-burden outliers — it is pushing the whole distribution to the left.
Action plan — reduce transfusion burden across the cohort
- Name the top 5%. Extract the list of patients in the 41+ group (7 patients). Give every one a documented anaemia review within 90 days.
- Attack ESA hyporesponse. For every high-burden patient, check CRP, albumin, ferritin, TSAT, PTH. Most have at least one correctable driver.
- Iron first, ESA second. Audit that every ESA dose increase was preceded by an iron-status check within the last 3 months.
- Hunt hidden blood loss. Faecal occult blood in all unexplained anaemia; upper and lower GI endoscopy in patients over 50 or with falling albumin.
- Protect the transplantable. For every transfusion in a transplant-eligible patient: document indication, alternatives considered, and notify the transplant team.
- Anaemia nurse / pharmacist role. One named person owning the anaemia pathway reduces transfusion burden faster than any protocol change alone.
- Target the mid-tier. The 29 patients in the 11–40 unit range are the group where a 12-month structured anaemia QI project has the highest yield.
- Budget the top 5%. Forecast red-cell consumption from the top-burden patients so procurement is not driven by the average.
- Benchmark. Compare mean units per patient-year with your national registry. Report quarterly.
