Perioperative protocol to reduce blood transfusions in total knee o hip replacement patients
Article in Revista de la Facultad de Ciencias Medicas (Cordoba, Argentina), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Introduction: Patient Blood Management (PBM) programs improve patient care and reduce health costs. It includes detection of presurgical anemia, reduction of blood loss and improvement of patient-specific anemic reserve. The aim of this study is to assess the effect of a PBM program on transfusion rate, length of stay (LOS) and adverse events. Methods: We developed a retrospective observational study. We included patients who underwent total hip (THR) o knee replacement (TKR). Our PBM involved preoperative assessment, administration of 2 doses of tranexamic acid, application of restrictive transfusion criteria and use of IV iron. We compared results between the group of patients before and the one after the PBM implementation. Results: We included 179 patients (80 TKR and 99 THR) who underwent surgery before PBM implementation from January to December 2014 (Group A), and 187 patients (103 TKR and 84 THR) who underwent arthroplasty after PBM application from January to November 2016 (Group B). In Group A, hemoglobin drop was larger than in Group B, for TKR (5.1±1.2 vs. 4.2±1.2 g/dl; p<0,05) and for THR (4.7±1.3 vs. 3.8±1.3 g/dl; p<0,05). In group A, more patients were transfused (31.8% vs. 2.7%; p<0.001). LOS was longer for patients in group A, in both surgeries (for TKA, 3.98±1.4days vs. 2.99±0.95 days; p<0.0001; for THA 3.68±1.06days vs. 2.88±0.75days; p<0.0001). No significant differences were found regarding adverse events. Conclusion: Our PBM program saved transfusions after primary TKR and THR and lowered LOS, without risking patients to higher number of complications or death.
