Incidence of alloantibody formation after ABO-D or extended matched red blood cell transfusions: a randomized trial (MATCH study).

Background: Most incidentally transfused patients receive only ABO-D-compatible transfusions and antibodies are formed in up to 8%. The effect of extended (c, C, E, K, Fy(a) , Jk(a) , and S antigens) matched (EM) and ABO-D-matched red blood cell (RBC) transfusions on the incidence of new clinically relevant RBC antibody formation after a first elective transfusion event in surgical patients was studied.

Study Design And Methods: A multicenter randomized trial was performed in nontransfused patients who were scheduled to experience a single elective transfusion event of maximal 4 RBC units.

Cell Salvage in Hip and Knee Arthroplasty: A Meta-Analysis of Randomized Controlled Trials.

Background: Cell salvage is used to reduce allogeneic red blood-cell (RBC) transfusions in total hip arthroplasty (THA) and total knee arthroplasty (TKA). We performed a meta-analysis to assess the effectiveness of cell salvage to reduce transfusions in THA and TKA separately, and to examine whether recent trials change the conclusions from previous meta-analyses.

Methods: We searched MEDLINE through January 2013 for randomized clinical trials evaluating the effects of cell salvage in THA and TKA.

Perceived barriers among physicians for stopping non-cost-effective blood-saving measures in total hip and total knee arthroplasties.

Background: Despite evidence that the blood-saving measures (BSMs) erythropoietin (EPO) and intra- and postoperative blood salvage are not (cost-)effective in primary elective total hip and knee arthroplasties, they are used frequently in Dutch hospitals. This study aims to assess the impact of barriers associated with the intention of physicians to stop BSMs.

Study Design And Methods: A survey among 400 orthopedic surgeons and 400 anesthesiologists within the Netherlands was performed.

De-implementation of expensive blood saving measures in hip and knee arthroplasties: study protocol for the LISBOA-II cluster randomized trial.

Background: Despite evidence that erythropoietin and intra- and postoperative blood salvage are expensive techniques considered to be non-cost-effective in primary elective total hip and knee arthroplasties in the Netherlands, Dutch medical professionals use them frequently to prevent the need for allogeneic transfusion. To actually change physicians' practice, a tailored strategy aimed at barriers that hinder physicians in abandoning the use of erythropoietin and perioperative blood salvage was systematically developed. The study aims to examine the effectiveness, feasibility and costs of this tailored de-implementation strategy compared to a control strategy.

Patient blood management in elective total hip- and knee-replacement surgery (part 2): a randomized controlled trial on blood salvage as transfusion alternative using a restrictive transfusion policy in patients with a preoperative hemoglobin above 13 g/dl.

Background: Patient blood management is introduced as a new concept that involves the combined use of transfusion alternatives. In elective adult total hip- or knee-replacement surgery patients, the authors conducted a large randomized study on the integrated use of erythropoietin, cell saver, and/or postoperative drain reinfusion devices (DRAIN) to evaluate allogeneic erythrocyte use, while applying a restrictive transfusion threshold. Patients with a preoperative hemoglobin level greater than 13 g/dl were ineligible for erythropoietin and evaluated for the effect of autologous blood reinfusion.

Patient blood management in elective total hip- and knee-replacement surgery (Part 1): a randomized controlled trial on erythropoietin and blood salvage as transfusion alternatives using a restrictive transfusion policy in erythropoietin-eligible patients.

Background: Patient blood management combines the use of several transfusion alternatives. Integrated use of erythropoietin, cell saver, and/or postoperative drain reinfusion devices on allogeneic erythrocyte use was evaluated using a restrictive transfusion threshold.

Methods: In a factorial design, adult elective hip- and knee-surgery patients with hemoglobin levels 10 to 13 g/dl (n = 683) were randomized for erythropoietin or not, and subsequently for autologous reinfusion by cell saver or postoperative drain reinfusion devices or for no blood salvage device.

Frequent use of blood-saving measures in elective orthopaedic surgery: a 2012 Dutch blood management survey.

Background: Blood loss in hip and knee arthroplasties may necessitate allogeneic blood transfusions. Different blood-saving measures (BSMs) were introduced to reduce these transfusions. Purpose of the present study was to assess the frequency of BSM use, stratified by type and hospital setting of orthopaedic departments in the Netherlands.

Patients with severe radiographic osteoarthritis have a better prognosis in physical functioning after hip and knee replacement: a cohort-study.

Introduction: Although Total Hip and Knee Replacements (THR/TKR) improve Health-Related Quality of Life (HRQoL) at the group level, up to 30% of patients are dissatisfied after surgery due to unfulfilled expectations. We aimed to assess whether the pre-operative radiographic severity of osteoarthritis (OA) is related to the improvement in HRQoL after THR or TKR, both at the population and individual level.

Methods: In this multi-center observational cohort study, HRQoL of OA patients requiring THR or TKR was measured 2 weeks before surgery and at 2-5 years follow-up, using the Short-Form 36 (SF36).

Designing a strategy to implement cost-effective blood transfusion management in elective hip and knee arthroplasties: a study protocol.

Background: Total hip and knee arthroplasties are two of the most commonly performed procedures in orthopedic surgery. Different blood-saving measures (BSMs) are used to reduce the often-needed allogenic blood transfusions in these procedures. A recent large randomized controlled trial showed it is not cost effective to use the BSMs of erythropoietin and perioperative autologous blood salvage in elective primary hip and knee arthroplasties.

Bisoprolol and fluvastatin for the reduction of perioperative cardiac mortality and myocardial infarction in intermediate-risk patients undergoing noncardiovascular surgery: a randomized controlled trial (DECREASE-IV).

Objective: This study evaluated the effectiveness and safety of beta-blockers and statins for the prevention of perioperative cardiovascular events in intermediate-risk patients undergoing noncardiovascular surgery.

Summary Background Data: Beta-blockers and statins reduce perioperative cardiac events in high-risk patients undergoing vascular surgery by restoring the myocardial oxygen supply/demand balance and/or stabilizing coronary plaques. However, their effects in intermediate-risk patients remained ill-defined.

Effects of transfusion with red cells filtered to remove leucocytes: randomised controlled trial in patients undergoing major surgery.

Objective: To compare postoperative complications in patients undergoing major surgery who received non-filtered or filtered red blood cell transfusions.

Design: Prospective, randomised, double blinded trial.

Setting: 19 hospitals throughout the Netherlands (three university; 10 clinical; six general).
