Attitude changes in prescribing intravenous iron supplementation in different settings at a hospital consortium in Italy.

BACKGROUND: Iron deficiency anaemia is a public health problem. In case oral iron treatment is ineffective, poorly tolerated or contraindicated, the intravenous route becomes the first choice. The aim of the study was to evaluate the shift between ferrous gluconate (FG) and ferric carboxymaltose (FCM) usage at our hospitals over the years. We also performed a cost comparison between pre and post-FCM availability periods, taking into account the acquisition costs of both intravenous iron and red blood cell units (PRBC). STUDY DESIGN AND METHODS: The amount and costs of FG and FCM released by hospital Pharmacy Services from 2010 to 2019 were analysed, along with the number of transfused PRBC units in the same timeframe. RESULTS: Overall, the proportion of FCM usage rose from 8.6 % in 2014 to 71.9 % in 2019, as percentage of total intravenous iron released. After exclusion of haemodialysis, where FG is still widely used, the FCM use in the last four years raised from 12.9% to 92.5%. Despite the higher FCM cost, the mean yearly expenditure for intravenous iron plus PRBC units did not differ between pre- and post-FCM eras (2010-2013, € 2,396,876 € versus 2014-2019, € 2,307,875 - p = 0.234), as a result of a net decrease of PRBC usage, namely from 15,083 to 12,654 (-16.1 %), respectively. DISCUSSION: Intravenous iron has a major role in treating iron deficiency anaemia in several settings. Third generation compounds are paving the way to more updated and safer treatments.

Impact of gender parity on preoperative anaemia prevalence and Patient Blood Management practice.

BACKGROUND: Anaemia is a common finding in the preoperative setting, affecting around one-third of patients for whom major surgery is programmed. Moreover, preoperative anaemia has been shown to worsen patient outcome and increase length of hospital stay and costs. In the field of preoperative anaemia correction, a recent Consensus statement suggested reviewing the classic World Health Organization (WHO) criteria in adults by aligning the haemoglobin cut-off to 13 g/dL for both genders. The aim of our study was to assess the differences in terms of prevalence, transfusion rate, transfusion trigger, and blood losses according to gender in a mixed population of surgical patients. MATERIAL AND METHODS: We reviewed data of 610 consecutive patients undergoing elective major surgery at a tertiary care hospital during a 9-month period. Transfusion rate and transfusion triggers were recorded, analysed and stratified by haemoglobin class, with a particular focus on the 12.0-12.9 g/dL range. RESULTS: Since the anaemia threshold was redefined at 13 g/dL for both genders, its prevalence rose from 26.4 to 39.5% (161/610 vs 241/610; p<0.001) in the overall population and from 22.7 to 49.3% (68/300 vs 148/300; p<0.001) in women. Eighty women (26.7%) fell in the haemoglobin 12.0-12.9 g/dL range, and this category was the most represented among transfused women (34.0%). There was no statistical difference in transfusion triggers or overall transfusion rate between genders. Subjects of both genders were transfused at the same haemoglobin level (8.1 g/dL), but women reached the transfusion trigger after less red cell mass loss than men, i.e. 377 mL (249-472 mL) vs 528 mL (356-717 mL), respectively (p<0.001). DISCUSSION: Treatment of pre-surgical anaemia is one of the core principles of Patient Blood Management. Aligning the haemoglobin threshold between genders in the management of pre-surgical anaemia may result in a lower transfusion rate, but in an increased workload for medical staff in the preoperative phase.

Early intravenous iron administration in the Emergency Department reduces red blood cell unit transfusion, hospitalisation, re-transfusion, length of stay and costs.

BACKGROUND: Moderate to severe iron deficiency anaemia is a common finding in patients admitted to the Emergency Department (ED). According to Patient Blood Management principles, intravenous iron should be the therapy of choice instead of blood transfusion for selected cases affected by chronic iron deficiency anaemia. However, this option is only rarely taken into account by physicians in the ED. As a result, in many circumstances, treatment of iron deficiency anaemia in the ED can differ from that of the Anaemia Clinic. With the aim of reducing inappropriate transfusions, and to implement intravenous iron usage, we shared a specific protocol with the ED. MATERIAL AND METHODS: We reviewed the medical records of all subjects admitted to the ED (n=267, Post-protocol group) with hemoglobin ≤9.0 g/dL and mean corpuscular volume <80 fL in a 13-month period, except if the massive transfusion protocol was activated, and results were compared with an equivalent Pre-protocol historical cohort (n=226). RESULTS: In comparison with the Pre-protocol series, the number of patients transfused did not change, but the appropriateness in terms of transfusion and red blood cell volume transfused improved sharply (87.0 vs 13.3%; p<0.001) with a significant increase in intravenous iron administration (50.2 vs 4.4% of cases; p<0.001). As a positive consequence, both the time spent in the ED by patients who were then directly discharged and costs per subject treated dropped by 37.9% and 59.0%, respectively. Treatment with infusion only in comparison with transfusion only led to a statistically significant Relative Risk reduction in transfusion on the ward and post-discharge transfusion of 55.6% and 44.4%, respectively. DISCUSSION: The implementation of Patient Blood Management principles and early intravenous iron therapy in the Emergency Department have proved to be effective tools to optimise resources both in terms of units transfused and costs.

Efficacy of a strict surveillance policy towards inappropriateness of plasma transfusion.

BACKGROUND: Plasma transfusion is not without risks. Despite a limited spectrum of indications, plasma is frequently used as prophylaxis in non-bleeding patients, to correct altered coagulation tests. A high rate of inappropriate use of plasma transfusion is frequently reported, as well as underdosage. STUDY DESIGN AND METHODS: Since 2010 we started an education program that occurred in several phases to disseminate the knowledge of plasma transfusion guidelines. Since 2014 a 'zero tolerance' policy was applied: except for massive bleedings, plasma requests were prospectively evaluated, rejecting those without an appropriate indication. When indicated, at least 10 mL/Kg b.w.were issued. The previous five year period (2005-2009) served as control. RESULTS: The number of patients transfused/year decreased by 67.6% vs the control period (149 vs 460), and the liters of plasma issued/year decreased by 70.4% (233 vs 795). The deepest fall was observed in acute care wards (-70.8%). The mean volume transfused per episode raised from 731 mL ±â€¯70 to 879 mL ±â€¯154. The Prothrombin Time ratio at the moment of transfusion request increased from a mean of 1.35 (Interquartile range 1.20-2.64) in the control period to 1.62 (Interquartile range 1.43-1.98) in the last period (p < 0.001). CONCLUSION: With a proactive educational approach a remarkable reduction of plasma order and administration has been obtained, without any consequence on morbidity and mortality and with an estimated saving since 2014 of 750,000 €. A 'zero tolerance' policy can be effectively implemented only with a thorough workup with the local physicians, including repeated rounds of information and refreshing of the updated transfusion practice and knowledge of the established guidelines over the time.
