The following procedure was adopted when using GRADE: The GDG assessed the evidence by outcome in order to determine if there was, or potentially was, a clinically important benefit, a clinically important harm or no clinically important difference between interventions. For example, if p value was reported as 'p≤0.001', the calculations for standard deviations will be based on a p value of 0.001. Excluded studies by review question (with the reasons for their exclusion) are listed in Appendix P in the full guideline appendices. Guideline Transfusion. Key information was extracted on the study's methods, PICO (patient, intervention, comparison and outcome) factors and results. Similar forms of words (for example, 'Do not offer…') are used when the GDG is confident that an intervention will not be of benefit for most patients. For example, the population in reviews evaluating the threshold and target levels for platelet transfusion were stratified on the basis of haematology and non-haematology patients and the presence or absence of bleeding. Blood transfusions carry risks, are costly, and the supply of blood is limited. National Clinical Guideline Centre. This assessment was carried out by the GDG for each critical outcome, and an evidence summary table was produced to compile the GDG's assessments of clinical importance per outcome, alongside the evidence quality and the uncertainty in the effect estimate (imprecision). However, there is often a closer balance between benefits and harms, and some patients would not choose an intervention whereas others would. <> Data from 63 randomized clinical trials and 82 observational studies were analyzed. Search strategies were quality assured by cross-checking reference lists of highly relevant papers, analysing search strategies in other systematic reviews, and asking GDG members to highlight any additional studies. Blood Transfusions for Patients with Acute Upper Gastrointestinal Bleeding. No evidence was found on transfusions specifically for young people (age 16 to 18 years). Study type and population in qualitative research can differ widely, meaning that themes that may only be identified by one or a few studies can provide important new information. Some recommendations can be made with more certainty than others. This is wasteful of a scarce and costly resource and puts patients at unnecessary risk. The wording of the evidence statements reflects the certainty or uncertainty in the estimate of effect. However, in cases where standard deviations were not reported per intervention group, the standard error (SE) for the mean difference was calculated from other reported statistics (p values or 95% CIs); meta-analysis was then undertaken for the mean difference and SE using the generic inverse variance method in RevMan5. Appraising the Quality of Evidence by Outcomes. The GDG considered the 'strength' of recommendations. Only consider giving more than a single dose of platelets in a transfusion for patients with severe thrombocytopenia and bleeding in a critical site, such as the central nervous system (including eyes). 24). After each single-unit red blood cell transfusion (or equivalent volumes calculated based on body weight for children or adults with low body weight), clinically reassess and check haemoglobin levels, and give further transfusions if needed. Randomised trials, non-randomised trials, and observational studies were included in the evidence reviews as appropriate. Results were presented in GRADE profiles ('GRADE tables'), which consist of 2 sections: the 'Clinical evidence profile' table includes details of the quality assessment, while the 'Clinical evidence summary of findings' table includes pooled outcome data, where appropriate, an absolute measure of intervention effect and the summary of quality of evidence for that outcome. Consider cryoprecipitate transfusions for patients without major haemorrhage who have: Do not offer cryoprecipitate transfusions to correct the fibrinogen level in patients who: Consider prophylactic cryoprecipitate transfusions for patients with a fibrinogen level below 1.0 g/litre who are having invasive procedures or surgery with a risk of clinically significant bleeding. Data Synthesis for Qualitative Study Reviews. By providing access to this patient information, it is not the intention of NGC to provide specific medical advice for particular patients. For some interventions, the GDG is confident that, given the information it has looked at, most patients would choose the intervention. NICE has not yet verified this content to confirm that it accurately reflects that original NICE guidance and therefore no guarantees are given by NICE in this regard. %���� Available from the, Patient groups with special transfusion needs, such as foetuses, neonates and children under 1 year old, pregnant women, and patients with haemoglobinopathies, Specialist areas already covered by National Institute for Health and Care Excellence (NICE) guidelines, for example, patients with anaemia in chronic kidney disease, upper gastrointestinal bleeding and trauma and massive haemorrhage, Alternatives to blood transfusion for patients having surgery, Monitoring for acute blood transfusion reactions, Electronic patient identification systems such as patient identification band, bar code or radiofrequency identification (RFID) to ensure patient safety during blood transfusions, Prothrombin complex concentrates transfusion, Providing information and support to patients and family members/carers, The patient has anaemia and meets the criteria for blood transfusion, but declines it because of religious beliefs or other reasons, or, The appropriate blood type is not available because of the patient's red cell antibodies, Have iron-deficiency anaemia and cannot tolerate or absorb oral iron, or are unable to adhere to oral iron treatment (see the NICE guideline on, Are diagnosed with functional iron deficiency, Are diagnosed with iron-deficiency anaemia, and the interval between the diagnosis of anaemia and surgery is predicted to be too short for oral iron to be effective, Need regular blood transfusions for chronic anaemia, Severe bleeding (WHO grades 3 and 4 below), Bleeding in critical sites, such as the central nervous system (including eyes), The specific procedure the patient is having, Whether the patient's platelet count is falling, Any coexisting causes of abnormal haemostasis, Are not having invasive procedures or surgery with a risk of clinically significant bleeding, Unlimited Access to Thousands of Summaries, Personalized Content Recommendations and Alerts, Access Saved Content on All Mobile Devices. Thank you for being a user of Guideline Central! In this guideline a level of 80–100 g/litre was used for patients with acute coronary syndrome, but further studies are needed to determine the optimal transfusion threshold for patients with chronic cardiovascular disease. If no sensitivity analysis was found to completely resolve statistical heterogeneity then a random-effects (DerSimonian and Laird) model was employed to provide a more conservative estimate of the effect. The Serious Hazards of Transfusion (SHOT) scheme estimated that in 2014 the risk of transfusion-related death was 5.6 per million blood components issued, and the risk of transfusion-related major morbidity was 63.5 per million blood components issued, although it was not always certain that transfusion was the direct cause of death or major morbidity. Clinical trials funded by the NHLBI helped determine that the previous blood transfusion guidelines sometimes led to unnecessary transfusions. For example, if evaluating mortality with a relative risk of 1.25 (1.15, 3.30) and an absolute risk reduction of 75 more per 1000 participants, the GDG were asked if 75 more deaths per 1000 was a clinically important harm and this was noted accordingly. When we collect your data through site visits and account creation, we agree to never sell that information to third-parties. Critically appraised relevant studies using the economic evaluations checklist as specified in The guidelines manual. The decision to adopt any of the recommendations cited here must be made by practitioners in light of individual patient circumstances, the wishes of the patient, clinical expertise and resources. London (UK): National Institute for Health and Care Excellence; 2015 Nov. (NICE guideline; no. Where data from observational studies were included, the GDG decided that the results for each outcome should be presented separately for each study and meta-analysis was not conducted. The GDG were asked to assess if the absolute risk difference for each outcome was indicative of a clinically important benefit or harm and this was noted accordingly. which compares the size of the treatment effect to the extent of between-trials variation. The same point estimate but in the opposite direction would apply if the outcome was negative. Guideline recommendations should be based on the expected costs of the different options in relation to their expected health benefits (that is, their 'cost-effectiveness') rather than the total implementation cost. Blood transfusions are a cornerstone of modern medicine and much progress has been made in transfusion medicine since the establishment of their regular use in clinical practice. External Peer Review Internal Peer Review. In these circumstances the recommendation is generally weaker, although it may be possible to make stronger recommendations about specific groups of patients. Blood transfusion. This may happen, for example, if some patients are particularly averse to some side effect and others are not. After results were pooled, the overall quality of evidence for each outcome was considered. This type of analysis simultaneously compares multiple treatments in a single meta-analysis, preserving the randomisation of randomised controlled trials (RCTs) included in the reviews of direct comparisons trials. The guideline includes recommendations on: Full guideline. National Guidelines on Screening Donated Blood for TTIs. London (UK): National Institute for Health and Care Excellence (NICE); 2012 Nov. The details of declared interests and the actions taken are shown in Appendix B in the full guideline appendices (see the "Availability of Companion Documents" field). However, for some outcomes this differed and was assessed on a case by case basis. By updating our privacy policy with clearer language, our goal is to help you better understand what data we collect and how we use that information. The GDG was convened by the NCGC and chaired in accordance with guidance from NICE. 6 0 obj Standards for Blood Banks and Transfusion Services for additional information and policies, especially in the areas of recipient sample identification, compatibility testing, issue and transfusion of blood and blood components, investigation of transfusion reactions, and proper record-keeping practices. Studies that only reported cost per hospital (not per patient), or only reported average cost-effectiveness without disaggregated costs and effects, were excluded. For example, all RCTs started as High and the overall quality became Moderate, Low or Very low if 1, 2 or 3 points were deducted respectively. These criteria are detailed in Sections 4.3.6 to 4.3.9 in the full version of the guideline.

See Appendices F and I in the full guideline appendices for economic article selection and economic evidence tables. transfusion, and neonatal isoerythrolysis. For continuous outcomes, measures of central tendency (mean) and variation (standard deviation) were required for meta-analysis. The PBM International Consensus Conference met in 2018 and evaluated key areas of the PBM field, including preoperative anemia, RBC transfusion thresholds, and implementation of PBM programs. Searching for unpublished literature was not undertaken. Available from the, Blood transfusion. The patient information is not reviewed by NGC to establish whether or not it accurately reflects the original guideline's content. Reassess the patient's clinical condition and repeat the coagulation tests after fresh frozen plasma transfusion to ensure that they are getting an adequate dose, and give further doses if needed. This patient information has been derived and prepared from a guideline for health care professionals included on NGC by the authors or publishers of that original guideline. Use an adult dose of 2 pools when giving cryoprecipitate transfusions (for children, use 5–10 ml/kg up to a maximum of 2 pools). The GDG considered the side effects of intravenous (IV) iron, as all preparations carry a small risk of adverse reactions which can be life threatening if not treated promptly. Guideline 1 Informed Consent for Administration of Blood, Blood Components and or Plasma Protein Products Page 3 of 5 MTBPRM 2019 Manitoba Transfusion Best Practice Resource Manual 2019 1.8 The physician/authorized practitioner must document, in the patient’s health record, why informed consent was not obtained. Model inputs and assumptions were reported fully and transparently. For more details about the assessment of applicability and methodological quality see the economic evaluation checklist (Appendix F of The guidelines manual and the health economics review protocol in Appendix D in the full guideline appendices). Clinical Algorithm Mobile Device Resources Patient Resources Resources. 24). Information for the public. When complications do occur, they're typically mild. Search. Secondly, whether the net benefit justified any differences in costs was assessed. The evidence statements are presented by outcome and encompass the following key features of the evidence: The NICE economic evidence profile has been used to summarise cost and cost-effectiveness estimates. No papers published after this date were considered. 26 p. (NICE guideline; no. Conference abstracts were not automatically excluded from the review but were initially assessed against the inclusion criteria and then further processed only if no other full publication was available for that review question. The results were subject to sensitivity analysis and limitations were discussed. If your body is missing one or more of the components that make up … Where exclusions occurred on this basis, this is noted in the relevant section. Methods, evidence and recommendations. Evidence from 14 randomised controlled trials (RCTs) comparing erythropoietin (EPO) with placebo/no EPO showed an increase in mortality and the number of patients with thrombotic complications in the EPO group compared to the placebo group, but there was considerable uncertainty in the effect estimates. A frequently identified theme may indicate an important issue for the review, but frequency of theme is not the only indicator of importance. 23: Specification for the uniform labelling of blood, blood components and blood donor samples 24: Specification for the uniform labelling of human tissue products using ISBT 128 25: Standards for electronic data interchange within the UK Blood Transfusion Services Further research is very unlikely to change confidence in the estimate of effect. The assessment of net benefit was moderated by the importance placed on the outcomes (the GDG's values and preferences), and the confidence the GDG had in the evidence (evidence quality). However, facilities should develop local procedures and protocols using relevant produ ct information and other jurisdictional resources (e.g. This guideline meets NGC's 2013 (revised) inclusion criteria. Reduction in inappropriate use of blood components and use of alternatives to transfusion will improve patient care and reduce hospital costs. It does not make recommendations relating to specific conditions. The output was expressed as the probability of each treatment being the best for an outcome and as effect estimates for how much each treatment is better than the other treatments included in the network. With great pleasure we present the new online edition of the Canadian Blood Services’ Clinical Guide to Transfusion. • Universal blood groups for red blood cells (RBC) and plasma (FFP) available for immediate use. stream Studies published in languages other than English were not reviewed.
