Abstract
BACKGROUND The aim of this trial was to assess the effectiveness of quality improvement collaboratives to implement large-scale change in the National Health Service (NHS) in the UK, specifically for improving outcomes in patients undergoing primary, elective total hip or knee replacement. METHODS We undertook a two-arm, cluster randomised controlled trial comparing the roll-out of two preoperative pathways: methicillin-sensitive Staphylococcus aureus (MSSA) decolonisation (infection arm) and anaemia screening and treatment (anaemia arm). NHS Trusts are public sector organisations that provide healthcare within a geographical area. NHS Trusts (n = 41) in England providing primary, elective total hip and knee replacements, but that did not have a preoperative anaemia screening or MSSA decolonisation pathway in place, were randomised to one of the two parallel collaboratives. Collaboratives took place from May 2018 to November 2019. Twenty-seven Trusts completed the trial (11 anaemia, 16 infection). Outcome data were collected for procedures performed between November 2018 and November 2019. Co-primary outcomes were perioperative blood transfusion (within 7 days of surgery) and deep surgical site infection (SSI) caused by MSSA (within 90 days post-surgery) for the anaemia and infection trial arms, respectively. Secondary outcomes were deep and superficial SSIs (any organism), length of hospital stay, critical care admissions and unplanned readmissions. Process measures included the proportion of eligible patients receiving each preoperative initiative. RESULTS There were 19,254 procedures from 27 NHS Trusts included in the results (6324 from 11 Trusts in the anaemia arm, 12,930 from 16 Trusts in the infection arm). There were no improvements observed for blood transfusion (anaemia arm 183 (2.9%); infection arm 302 (2.3%) transfusions; adjusted odds ratio 1.20, 95% CI 0.52-2.75, p = 0.67) or MSSA deep SSI (anaemia arm 8 (0.13%); infection arm 18 (0.14%); adjusted odds ratio 1.01, 95% CI 0.42-2.46, p = 0.98). There were no significant improvements in any secondary outcome. This is despite process measures showing the preoperative pathways were implemented for 73.7% and 61.1% of eligible procedures in the infection and anaemia arms, respectively. CONCLUSIONS Quality improvement collaboratives did not result in improved patient outcomes in this trial; however, there was some evidence they may support successful implementation of new preoperative pathways in the NHS.

Abstract
INTRODUCTION The benefit of the femoral canal bone plug during total knee arthroplasty (TKA) in reducing blood loss has never been proven. The aim of this meta-analysis was to determine whether the femoral canal bone plug significantly reduces blood loss in primary TKA. METHOD All studies published before December 2021 were searched. The inclusion criteria were randomized controlled trials comparing blood loss between TKA with plugged and unplugged femoral intramedullary canal, respectively. The primary outcome was postoperative hemoglobin reduction. RESULTS Five studies with a total of 717 patients (361 in the plugged group, 356 in the unplugged group) met the criteria for inclusion in the meta-analysis. The mean difference in hemoglobin level between the two groups was 0.92 g/dL, with significantly less hemoglobin reduction in the plugged group (95% confidence interval [CI] - 1.64 to - 0.21, p = 0.01). The patients in the plugged group also had a significantly lower risk of receiving a blood transfusion (risk ratio 0.58, 95% CI 0.47-0.73, p < 0.00001). CONCLUSIONS This meta-analysis demonstrates that using a femoral canal bone plug can significantly reduce blood loss and lower the risk ratio of blood transfusion in patients undergoing TKA.

Abstract
BACKGROUND Adductor canal block (ACB) provides effective analgesia management after arthroscopic knee surgery. However, there is insufficient data about performing ACB before or after inflation of a thigh tourniquet. We aimed to investigate the efficacy of ACB when it is performed before and after thigh tourniquet and evaluate motor weakness. METHODS ACB was performed before the tourniquet inflation in the PreT group, it was performed after the inflation of the tourniquet in the PostT group. In the PO group, ACB was performed at the end of surgery after disinflation of the tourniquet. RESULTS There were no statistical differences between the groups in terms of demographic data. Opioid consumption showed no statistically significant differences (for total consumption; p = 0.5). The amount of rescue analgesia administered and patient satisfaction were also not significantly different between groups. There was no significant difference in terms of static and dynamic VAS scores between groups (for 24 hours; p = 0.3, p = 0.2 respectively). The incidence of motor block was higher in the PreT group (eight patients) than in the PostT group (no patients) and in the PO group (only one patient) (p = 0.005). CONCLUSIONS Using a tourniquet before or after ACB may not result in any differences in terms of analgesia; however, applying a tourniquet immediately after ACB may lead to muscle weakness.

Global spine journal. 2021;:2192568220979821
Abstract
STUDY DESIGN Systematic review. OBJECTIVES Synthesize previous studies evaluating clinical utility of preoperative Hb/Hct and HbA1c in patients undergoing common spinal procedures: anterior cervical discectomy and fusion (ACDF), posterior cervical fusion (PCF), posterior lumbar fusion (PLF), and lumbar decompression (LD). METHODS We queried PubMed, Embase, Cochrane Library, and Web of Science for literature on preoperative Hb/Hct and HbA1c and post-operative outcomes in adult patients undergoing ACDF, PCF, PLF, or LD surgeries. RESULTS Total of 4,307 publications were assessed. Twenty-one articles met inclusion criteria. PCF AND ACDF Decreased preoperative Hb/Hct were significant predictors of increased postoperative morbidity, including return to operating room, pulmonary complications, transfusions, and increased length of stay (LOS). For increased HbA1c, there was significant increase in risk of postoperative infection and cost of hospital stay. PLF: Decreased Hb/Hct was reported to be associated with increased risk of postoperative cardiac events, blood transfusion, and increased LOS. Elevated HbA1c was associated with increased risk of infection as well as higher visual analogue scores (VAS) and Oswestry disability index (ODI) scores. LD: LOS and total episode of care cost were increased in patients with preoperative HbA1c elevation. CONCLUSION In adult patients undergoing spine surgery, preoperative Hb/Hct are clinically useful predictors for postoperative complications, transfusion rates, and LOS, and HbA1c is predictive for postoperative infection and functional outcomes. Using Hct values <35-38% and HbA1c >6.5%-6.9% for identifying patients at higher risk of postoperative complications is most supported by the literature. We recommend obtaining these labs as part of routine pre-operative risk stratification. LEVEL OF EVIDENCE III.

Nursing open. 2021;8(1):80-86
Abstract
AIM: To identify the effect of enhanced recovery after surgery (ERAS) and rapid rehabilitation concepts on the outcomes of patients with haemophilia A undergoing total knee arthroplasty. DESIGN Randomized controlled trial. METHODS The primary endpoint was postoperative hospital stay. The secondary endpoints were pain scores, joint function scores, haemoglobin levels at 3 and 7 days after surgery and satisfaction with hospitalization. RESULTS Thirty-two patients were enrolled. Compared with the routine nursing group, the ERAS group showed shorter postoperative hospital stay (14.2 SD 0.8 vs. 16.6 ± 1.3 days, p < .001), smaller amounts of blood transfusion (924 SD 317 vs. 1,263 SD 449 ml, p = .020) and coagulation factors (37,325 SD 5,996 vs. 48,475 SD 8,019 U, p < .001), lower pain scores at 3 (3.3 SD 0.7 vs. 4.3 SD 0.7, p = .002) and 7 (2.3 SD 0.7 vs. 2.8 ± 0.5, p = .015) days, lower hospital for special surgery knee scores at 3 (59.9 SD 7.8 vs. 53.6 SD 5.9, p = .016) and 7 (77.9 SD 6.9 vs. 71.1 ± 7.1, p = .009) days and higher satisfaction with hospitalization (94.3 SD 1.4 vs. 92.7 SD 1.6, p = .004).

Chen Z, Ma Y, Li Q, Deng Z, Zheng Q
Annals of palliative medicine. 2020
Abstract
BACKGROUND As Asian populations, Chinese have a lower rate of high-risk gene mutations in venous thrombosis. Therefore, individual patient risk assessment, rather than a "blanket policy", is considered the best thromboembolism prophylaxis for Chinese. The purpose of this study was to evaluate the effectiveness and safety of selective thromboembolism prophylaxis compared with conventional thromboembolism prophylaxis by risk stratification with thromboelastography (TEG) after joint arthroplasty in Chinese. METHODS Between August 2016 to August 2017, Chinese patients who underwent hip or knee arthroplasty were randomly divided into a selective anticoagulation group (SAG) and a conventional anticoagulation group (CAG). Participants and outcome assessors were blinded. In the SAG, an anticoagulant was used when TEG indicated hypercoagulability; while in the CAG, an anticoagulant was regularly used until one month after surgery. Outcome evaluation included effectiveness (defined as the incidence of VTE), and safety (defined as the incidence of bleeding events, poor wound healing, blood loss, and infection). RESULTS A total of 197 patients (79 in the SAG and 118 in the CAG) were included in the study. There was 1 case of deep vein thrombosis (DVT) in the SAG and 2 cases of DVT in the CAG, but there was no significant difference between the two groups. Hidden blood loss in the SAG was 707.4±539.8 mL and hidden blood loss in the CAG was 617±565.0 mL, respectively (P>0.05). No significant difference was observed in perioperative blood loss between the SAG and the CAG (1,024.9±597.9 and 1,139.3±620.9 mL, respectively). Volume of blood transfusion was 92.4±270.2 mL in the SAG and 224.6±416.3 mL in the CAG, respectively, while rate of transfusion was 13.9% in the SAG and 33.9% in the CAG, respectively, which were significantly different between the two groups (P<0.05). CONCLUSIONS In Chinese patients who underwent hip or knee arthroplasty, the efficacy of selective anticoagulation using TEG in risk stratification was comparable to that of conventional anticoagulation. Furthermore, the safety of selective anticoagulant prophylaxis was superior to that of conventional anticoagulant prophylaxis.

Abstract
BACKGROUND Perioperative autologous blood salvage and preoperative erythropoietin are not (cost) effective to reduce allogeneic transfusion in primary hip and knee arthroplasty, but are still used. This study aimed to evaluate the effectiveness of a theoretically informed multifaceted strategy to de-implement these low-value blood management techniques. METHODS Twenty-one Dutch hospitals participated in this pragmatic cluster-randomized trial. At baseline, data were gathered for 924 patients from 10 intervention and 1040 patients from 11 control hospitals undergoing hip or knee arthroplasty. The intervention included a multifaceted de-implementation strategy which consisted of interactive education, feedback on blood management performance, and a comparison with benchmark hospitals, aimed at orthopedic surgeons and anesthesiologists. After the intervention, data were gathered for 997 patients from the intervention and 1096 patients from the control hospitals. The randomization outcome was revealed after the baseline measurement. Primary outcomes were use of blood salvage and erythropoietin. Secondary outcomes included postoperative hemoglobin, length of stay, allogeneic transfusions, and use of local infiltration analgesia (LIA) and tranexamic acid (TXA). RESULTS The use of blood salvage (OR 0.08, 95% CI 0.02 to 0.30) and erythropoietin (OR 0.30, 95% CI 0.09 to 0.97) reduced significantly over time, but did not differ between intervention and control hospitals (blood salvage OR 1.74 95% CI 0.27 to 11.39, erythropoietin OR 1.33, 95% CI 0.26 to 6.84). Postoperative hemoglobin levels were significantly higher (beta 0.21, 95% CI 0.08 to 0.34) and length of stay shorter (beta -0.36, 95% CI -0.64 to -0.09) in hospitals receiving the multifaceted strategy, compared with control hospitals and after adjustment for baseline. Transfusions did not differ between the intervention and control hospitals (OR 1.06, 95% CI 0.63 to 1.78). Both LIA (OR 0.0, 95% CI 0.0 to 0.0) and TXA (OR 0.3, 95% CI 0.2 to 0.5) were significantly associated with the reduction in blood salvage over time. CONCLUSIONS Blood salvage and erythropoietin use reduced over time, but not differently between intervention and control hospitals. The reduction in blood salvage was associated with increased use of local infiltration analgesia and tranexamic acid, suggesting that de-implementation is assisted by the substitution of techniques. The reduction in blood salvage and erythropoietin did not lead to a deterioration in patient-related secondary outcomes. TRIAL REGISTRATION www.trialregister.nl, NTR4044.
