1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundHip fractures are associated with serious morbidity and mortality. Low haemoglobin at presentation has been shown to be associated with increased mortality in hip fracture patients. This comorbid patient group commonly receives packed red cell blood transfusions during their hospital admission, the impact of which is less clear. AIMS AND

objectivesWe aim to assess the rate, appropriateness and impact of blood transfusions on one-year mortality in hip fracture patients. We also aim to assess the impact of patients taking anticoagulant medications at presentation on the rates of blood transfusions in this patient group.

methodsA retrospective cohort study of 324 consecutive hip fracture patients. Data was collected from the national hip fracture database, electronic patient records and PACS.

results75 patients received a blood transfusion. Receiving a blood transfusion increased absolute risk of one-year mortality by 2.466 (p < 0.05). Adjusted for age, sex, comorbidities, residence prior to admission and time from presentation to surgery increased the risk of one-year mortality was 2.790 (p < 0.05).28% of patients who went on to receive a transfusion had a haemoglobin of less than 100 g/L at presentation. 94.6% of transfused patients had a pre-transfusion haemoglobin of less than 90 g/L. There was no increased risk of requiring a blood transfusion if anticoagulant medication was being taken at presentation.

conclusionReceiving a blood transfusion during an admission for hip fracture carried an increased risk of one-year mortality of almost two and a half times. With appropriate preoperative optimisation, taking an anticoagulant medication at presentation did not increase the risk of requiring a transfusion. Most blood transfusions were administered appropriately using thresholds. Just over a quarter of patients who received a transfusion had an admission haemoglobin of less than 100 g/L, showing it as a poor predictor of blood transfusion requirement during admission.
