    Abstract: Anemia and iron deficiency (ID) can impair quality of life and socioeconomic development. We evaluated the prevalence of anemia and ID in the adult Portuguese population in real-life contexts by gender, age, and pregnancy status. We performed a cross-sectional screening in adult individuals in mainland Portugal from 2013 to 2017. Participants completed a survey about demographics and signs or symptoms compatible with anemia, and ID and hemoglobin and ferritin concentrations were determined by point-of-care tests. We estimated and compared prevalence ratios (PR) of anemia and ID using Poisson regression with robust variance and the Wald chi-square test. We collected data from 11,030 individuals (26% men, 64% nonpregnant women, and 10% pregnant women). We found anemia in 51.8% (95% CI 50.1–53.4%) of nonpregnant women in fertile age, 46.6% (95% CI 44.7–48.6%) of nonpregnant women 〉 51 years, 38.2% (95% CI 35.4–41.1%) of pregnant women, and 33.3% (95% CI 31.6–35.1%) of men. The prevalence of ID was 72.9% (95% CI 71.4–74.4%) in nonpregnant women in fertile age, 50.5% (95% CI 48.5–52.4%) in nonpregnant women 〉 51 years, 94.8% (95% CI 93.3–96.0%) in pregnant women, and 28.9% (95% CI 27.3–30.6%) in men. We found significant associations between the prevalence of anemia or ID and nonpregnant women (PR: 1.50, 95% CI 1.42–1.59 or PR: 2.21, 95% CI 2.09–2.35, respectively), manifestation of signs or symptoms (PR: 1.19, 95% CI 1.53–1.23 or PR: 1.22, 95% CI 1.18–1.26), pregnant women (PR: 0.74, 95% CI 0.68–0.80 or PR: 1.30, 95% CI 1.27–1.33), and nonpregnant women ≤51 years (PR: 1.11, 95% CI 1.06–1.17 or PR: 1.42, 95% CI 1.36–1.48). In conclusion, anemia and ID represent moderate to severe public health problems, particularly among women in fertile age and in 3rd trimester, of pregnancy emphasizing the need to raise the public and health professionals’ awareness of these problems and their prevention, diagnosis, and treatment.

    Abstract: Abstract 1161 Background Heterogeneity in clinical practices worldwide for Venous Thromboembolism (VTE) is a major challengs. This concern led us to establish international good clinical practices guidelines (GCPG) for the management VTE in cancer patients (pts). Methods Twenty-four international experts (WG) worked with the methodological support of the French Cancer institute (INCa). All studies on cancer, venous thromboembolism (VTE, pulmonary embolism PE), and anticoagulant drugs (AC) published from 1996 to 2011 were searched using MEDLINE®database. Studies quality was evaluated double-blind manner by the methodologists using the GRADE appraisal grids. Main study outcomes were rates of VTE, major and minor bleeding, thrombocytopenia and death. Extracted data were entered in evidence tables and validated by the WG. High A, Moderate B, Low C, Very low D levels of evidence depended on study design, limitations, inconsistency, indirectness, imprecision and publication bias. Guidelines were classified as Strong (Grade 1) or Weak (Grade 2) based on GRADE. If absence of scientific evidence, the WG consensus judgement was defined as Best Clinical Practice (BCP). The GCP were then evaluated by 45 independent experts worldwide and 3 pt representatives using a specific grid. Results in cancer pts A) For initial treatment of established VTE: low molecular weight heparin (LMWH) is recommended [1B], Fondaparinux and unfractionated heparin (UFH) can be also used [2D] . Thrombolysis may be considered on a case-by-case basis, with attention to contraindication (bleeding risk) [BCP], Vena Cava Filters (VCF) may be considered if contraindication to AC of PE recurrence under optimal AC with periodic reassessment of contraindications to AC.VCF are not recommended for primary VTE prophylaxis [BCP] . For early maintenance (10 days-3 mths) and long-term treatment ( 〉 3 mths) of established VTE: LMWH are preferred over vitamin K antagonist (VKA) [1A]; LMWH should be used at least 3 mths After 3–6 mths, continuation of LMWH or VKA should be based on individual benefit-risk ratio [BCP] . If VTE recurrence, 3 options: switch from VKA to LMWH; increase in LMWH dose in pts treated with LMWH; VCF insertion [BCP]. B) To prevent postoperative VTE: LMWH once a day or low dose UFH 3 times a day are recommended; AC prophylaxis should start 12 to 2 hrs preoperatively and continued at least 7 to 10 days [ 1A]. No evidence support fondaparinux as an alternative to LMWH [2C] . The highest prophylactic dose of LMWH is recommended [ 1A]. Extended prophylaxis (4 weeks) after major laparotomy may be indicated if high VTE and low bleeding risks [2B] . For laparoscopic surgery, LMWH may be recommended as for laparotomy [BCP]. External compressions devices (ECD) are not recommended as monotherapy except if AC is contraindicated [ 2C] . C) In hospitalized medical cancer pts with reduced mobility, prophylaxis with LMWH UFH or fondaparinux [1B] is recommended. For ALL children and adults treated with L-asparaginase, depending on local policy and each pt prophylaxis may be considered [BCP] . In pts receiving chemotherapy, prophylaxis is not recommended routinely [1B]. Primary VTE prophylaxis VTE may be indicated for locally advanced or metastatic pancreatic [1B] or lung [2B] cancer pts treated with chemotherapy and having low bleeding risk. In pts treated by IMiDs with steroids and/or anthracycline, VTE prophylaxis is recommended: low or therapeutic VKA doses, LMWH at prophylactic doses and low-dose aspirin have shown similar effects [2C] . D) A brain tumor per se is not a contraindication to AC for established VTE [2C], for which we prefer LMWH [BCP] . LMWH or UFH are recommended postoperatively to prevent VTE in neurosurgery cancer pts [1A]. If creatinine clearance 〈 30 mL/min, we suggest UFH followed by VKA (from day 1) or LMWH adjusted to anti-Xa level to treat established VTE [BCP]; ECD may be applied and UFH used on a case-by-case basis [BCP] . If platelets 〉 50 G/L and no bleeding, full doses AC can be used for established VTE; if platelet 〈 50 G/L, treatment and dose depend on a case-by-case basis [BCP ]; if platelet 〉 80 G/L, AC prophylaxis may be used and if 〈 80 G/L, only on a case-by-case basis [BCP]. In pregnant cancer pts, standard treatment for established VTE and prophylaxis should be implemented [BCP] . Conclusion Dissemination and implementation of international GCPG for the management of VTE, the second cause of death in cancer pts, is a major public health priority. Disclosures: No relevant conflicts of interest to declare.

    Abstract: Multiple Myeloma is a malignant disease of the bone marrow plasma cells that mainly affects older people, and whose prognosis is reserved on relapsing or refractory disease. The arrival of CD38 monoclonal antibody daratumumab into the market allowed an increase in overall survival rate, with limited associated toxicity, for pre-treated multiple myeloma patients. However, this antibody interferes with pre-transfusion tests since erythrocytes also express, even at reduced levels, CD38 receptors. A literature review and discussion about this topic was performed by a board of Portuguese Immuno-hemotherapy experts. Based on the literature review, the mechanisms by which daratumumab interferes with pre-transfusion tests and may mask the presence of irregular antibodies in plasma of treated patients, which may result in difficulties in preparing and delivering results and blood components to be transfused, were identified and discussed. In addition, the applicable strategies in clinical practice to mitigate this interference were identified, namely the denaturing method of CD38 with dithiothreitol, considered an inexpensive, reproducible, reliable and validated technique, although with logistic limitations and should not be ignored. The experts also assessed and discussed the main concerns and priorities of transfusion medicine services, considering the limitations of this technique and its implication in routines for tranfusional support. The experts agreed on the importance of communication between physicians, hematologists, immuno-hemotherapy specialists, nurses and patients, as well as the need to align all methodologies to develop global and universal protocols to the various clinical analysis laboratory centers.

    Abstract: Patient Blood Management (PBM) describes a multidisciplinary approach that strives to optimize patients own blood and has been reported to reduce blood components utilization while achieving improved patient outcomes and reduced healthcare costs. The aim of this study was to evaluate the public health and economic impact related to the implementation of a nationwide PBM program in Portugal. METHODS: A decision-model comparing two scenarios (“current clinical practice” and “with PBM implementation”) was used to estimate the PBM impact including hospital-assisted patients from the following therapeutic areas: surgery (orthopaedic, cardiac and urologic), cardiology, oncology, gastrointestinal bleeding, abnormal uterine bleeding, hemodialysis, inflammatory bowel disease and pregnancy. Model inputs were obtained from Portuguese national health databases and literature review. The public health impact was measured in life years (LY) gained, disability-adjusted life years (DALY) reduction, hospital length of stay (LOS) and 30-day readmission rate reduction. The economic value was expressed in total and hospitalization costs savings. RESULTS: A total of 384,704 patients were eligible for PBM strategies. We estimated that a one year nationwide PBM implementation could avoid 594 premature deaths, representing a gain of 1,481 LY and a reduction of 3,660 DALYs relative to the current paradigm. An 8.4 percent and 37.3 percent reduction in length of stay and 30-day readmission rate are expected, respectively. This corresponds to EUR70.4 million savings in hospitalization costs. Although PBM closer monitoring would imply additional physician visits and medicines use, leading to EUR24.1 million in additional expenditure, in this population the overall PBM implementation can generate net savings of more than EUR67.7 million per year (6.3 percent reduction of public expenditure). CONCLUSIONS: The implementation of a nationwide PBM in Portugal may represent a great public health impact, especially in decreased mortality and disability, with substantial public expenditure reduction.

    Abstract: Background: The demand for allogeneic blood (packed red blood cells) has been progressively increasing. The introduction of safety measures substantially increased its cost and limited the available supply. Because both supply and demand for blood has not yet reached a plateau, namely in Portugal, the introduction and adoption of treatments that reduce transfusion, such as Erythropoiesis Stimulating Agents (ESA’S) for patients with chemotherapy induced anemia (CIA) is a welcome strategy to manage the hospital blood supply. Recently an advisory panel to the US Food and Drug Administration has recommended that the agency further limit the use of ESA’S, and in Europe, the European Medicines Agency (EMEA) emitted a statement that “cancer patients with a reasonably long life expectancy” should receive blood transfusions rather than take drugs for anemia. With these warnings we are probably going to see an increase in demand for blood. Estimating blood costs is a complex undertaking, surpassing simple versus demand economics, and is not simple or straightforward; the underlying issue is whether hospitals are billing appropriately for blood products and how extensively its value is calculated. The National Health Care System is making a huge effort to control the rising costs associated with the delivery of health services, namely developing a new allocation method for hospitals. Activity-based costing (ABC) is an approach to the management of resources that allows the ‘real’ resource costs and time of a service activity to be estimated. Traditional costing systems often group many costs together as overheads. The Accounting System for Activities in the Hospitals (SCAH) is outlined to evaluate detailed cost elements, understanding cost behaviour, which can facilitate future policy decisions, because policy makers have the opportunity to more fully understand the implications of incremental changes. We applied the SCAH to the Blood Bank of IPOFG Lisbon, in order to evaluate a far more accurate appraisal of the actual cost of the blood. The cost of correcting CIA is an open issue as both ESAS’S and Transfusion may offer symptomatic benefit. In Portugal the price of ESA’S, Erythropoietin alfa decreased almost 50% from 2000–2008, not including the final price, negotiated in each hospital. On the other hand, the price of one unit of packed RBCs continues to rise, and with different values, depending on the methodology used. Purpose: Evaluation of the costs of both alternatives to increase 1g of haemoglobin, in a hemato-oncological hospital, belonging to National Health Service and not for profit. Methods: We analysed the official prices of ESA’S between 2000–2008 published by the Ministry of Health. We used an activity – based approach to more fully account for the cost of blood, than present estimates, derived from the concept of activity-based costing (ABC). We applied this method to the process Chart flows of activities associated with blood collection facility and the others associated to the transfusion service. Results: Prices of Epoeitin - a (1000 UI/5μg) and Darbepoeitin according to National Catalogue Prices 2000 2001 2002 2003 2004 2005 2006 2007 2008 Epoietin-a €11,17 €7,20 €6,73 €6,52 €6,52 €6,12 €6,12 €6,12 €6,12 Darbepoeitin - - - €7,80 €7,00 €6,52 €6,52 €6,12 €6,12 Price of Packed RBC (2007), calculated using ABC methodology % Price (€) Personnel 25,32 90,26 Material to blood collection 6,47 23,07 Equipment 1,03 3,67 Common Costs 5,03 17,92 Reagents 3,69 13,15 Outsourcing 1,83 6,52 Structures 1,01 3,60 Laboratory analysis 15,85 56,50 Transfusion Session 39,77 141,75 Total 100% 356,44 Increment of 1g haemoglobin 1 unit of Packed RBC and transfusion session 30.000 UI EPO-a (fixed dose every week) 150 mg Darbepoeitin (fixed dose every week) €356.44 + €30* €183,6 × 2 = €367,2 * Haemovigilance network €183,6 × 4 = €734,4 The cost of 1 unit of packed RBC is equivalent a two fixed doses of EPO- a and Darbepoitin, respectively (30000 UI and 150 mg). Each hospital can negotiate catalogue adjusted prices for ESA’s, so if we presume that these values can be reduced by half, the price of 1 unit of packed RBC is equivalent to 4 fixed doses of treatment with ESA’s. Conclusions: Once the ability of ESA’s to reduce transfusions requirements has been documented in the literature, the costs of ESA’S and Transfusion might be another factor in determining which approach should be used.

    Abstract: Abstract 4357 Background Use of long term indwelling central venous catheter (CVC) is associated with symptomatic (Σ) events in up to 30% of cancer patients (pts), which may lead to pulmonary embolism (PE) and loss of the CVC. Lack of consensus on management of CVC related thrombosis (CVCT) and heterogeneity in clinical practices worldwide led us to establish international Good Clinical Practices Guidelines (GCPG) for the management of CRT in cancer pts. Methods The international working group (WG) met 4 times and worked 2 years with the methodological support and quality control of the French institute of Cancer (INCa). All studies on cancer, venous thromboembolism (VTE, including pulmonary embolism PE), and anticoagulant drugs (AC) published from 1996 to 2011 weree searched using MEDLINE®database. Meta-analyses, systematic reviews, randomized or non-randomized prospective or retrospective studies in the absence of randomized clinical trials, and abstracts only if a full paper had been accepted in a peer-reviewed medical journal were included in the analysis. The included studies concerned the prophylaxis and treatment of CVC in cancer pts. Studies in non-cancer pts, pts with a peripheral or dialysis catheter, or with a history of cancer in remission for more than 5 years were not considered. The main study outcomes were rates of proven catheter related thrombosis (CRT), extension of CRT, PE associated with CRT, major and minor bleeding, thrombocytopenia, and death. Quality of the studies was evaluated in a double-blind manner by the methodologists using the GRADE appraisal grids. Extracted data were entered in evidence tables, subsequently validated by all the WG. The level of evidence (High A, Moderate B, Low C, Very low D) depended on study design, limitations, inconsistency, indirectness, imprecision and publication bias. For each question, results analysis were summarized and discussed by the WG. Overall conclusions and recommendations were classified as Strong (Grade 1 Guideline) or Weak (Grade 2 Guideline) based on evidence levels, the balance between desirable/undesirable effects, values and preferencesand costs. In the absence of scientific evidence, judgment based on consensus within the WG was defined as Best Clinical Practice (BCP). The GCP were reviewed and evaluated using a specific grid in February 2012 by 45 independent experts in managing cancer pts worldwide and 3 pt representatives. Results Conclusion Dissemination and implementation of these international GCPG on the prevention and treatment of CRT in cancer ptsat each national level is a major public health priority, necssitating world wide collaboration. Disclosures: No relevant conflicts of interest to declare.

    Abstract: The present study aimed to characterize the prevalence of anemia and iron deficiency in older Portuguese adults, and to compare it with the prevalence in younger individuals. Methods A population‐based, cross‐sectional study (EMPIRE study) enrolling a representative sample of 6267 adults aged 〈 65 years and 1617 adults aged ≥65 years was carried out. Hemoglobin, ferritin, creatinine and C‐reactive protein levels were measured by Point‐of‐Care tests. Results Anemia was more prevalent ( P 〈 0.001) in participants aged ≥80 years (31.4%) compared with participants aged 〈 65 years (19.6%) and 65–79 years (17.3%). At a 30‐ng/mL ferritin cut‐off, iron deficiency was more prevalent in participants aged ≥80 years (42.8%) compared with participants aged 〈 65 years (31.5%) and 65–79 years (30.2%). Alternative ferritin cut‐offs showed overall similar patterns. Anemia and iron deficiency were significantly more prevalent in older individuals who self‐reported heart failure, coronary heart disease and gastritis. Anemia was more prevalent in participants aged 〈 65 years in the north of Portugal and participants aged ≥65 years in central Portugal, following the prevalence of iron deficiency in the regions. In all regions, anemia was more prevalent in participants aged ≥80 years (reaching 39.0% in Lisbon and Tagus Valley, and 51.0% in the south). Conclusions Anemia and iron deficiency are highly prevalent in older Portuguese adults, particularly among those aged ≥80 years. Better diagnosis, prevention and treatment strategies should be implemented taking into account the outstanding role of iron deficiency in older Portuguese adults, the differences between regions and the intrinsic characteristics of this population.

    Abstract: Introduction: Anaemia and iron deficiency are associated with increased mortality and poor surgical outcomes. Consensus in their definitions is expected to optimize their management, which is encompassed by patient blood management, providing patient-centred care while improving patient safety and clinical outcomes. Patient blood management implementation is even more relevant in contingency times and faces barriers due to lack of standardization, among others. The aim is to establish a consensus on these diagnoses and implement patient blood management principles in clinical practice in Portugal.Material and Methods: Eight experts in Transfusion Medicine, Haematology, Anaesthesiology, Internal Medicine, and Obstetrics/Gynaecology were assembled; a focus group was conducted, defining 33 statements. A Delphi panel was conducted, with experts from the clinical specialities named above as well as from General Surgery, Urology, and Orthopaedics.Results: The Delphi panel’s rounds had 70 (Round 1) and 46 (Round 2) respondents. Specialists were consensual in only two statements, on the existence of a preoperative patient blood management consultation for candidates to elective surgeries in which the use of blood derivatives is anticipated and, on the importance of the correction of postoperative anaemia and iron deficiency. Of the remaining 31 statements, 27 reached high agreement or disagreement by the respondents.Conclusion: Consensus was reached in only two (6%) of the 33 statements. There was a consensual agreement on the relevance of establishing patient blood management as the standard of care and of valuing preoperative and postoperative patient blood management interventions. Nevertheless, our results point to the lack of awareness regarding patient blood management principles – which could result in better postoperative outcomes, shorter hospitalizations, reduced costs and increased availability of beds. Training and literacy initiatives could help further implement patient blood management standards in Portuguese hospitals.
