Preoperative screening and intervention for mild anemia with low iron stores in elective hip and knee arthroplasty.

BACKGROUND: Preoperative anemia in patients undergoing elective hip and knee arthroplasty is associated with increased postoperative morbidity and mortality, red blood cell (RBC) transfusion, and length of stay (LOS). The aim of this study was to assess the effect of optimizing hemoglobin (Hb) levels before elective primary hip and knee arthroplasty. STUDY DESIGN AND METHODS: This is a prospective comparative cohort study of patients who underwent elective hip and knee arthroplasty before (control) and after (intervention) the launch of a Hb optimization program. Patients with anemia followed an agreed upon algorithm dependent on their medical history and blood variables taken on listing for surgery. The primary outcome for this study was the requirement for allogenic RBC transfusion. Secondary outcomes included hospital LOS, admission to critical care, readmission, medical complications, incidence of thromboembolic events, mortality, and costs. RESULTS: A total of 1814 control patients operated between February 2012 and February 2013 were compared to 1622 intervention patients operated between February 2013 and May 2014. In the intervention group transfusion was significantly reduced (108 [6%] vs. 63 [4.1%], p = 0.005) as well as readmission (81 [4.5%] vs. 48 [2.3%], p= 0.020) and critical care admission (23 [1.3%] vs. 9 [0.5%], p = 0.030). LOS was significantly reduced from 3.9 days to 3.6 days (p = 0.017). The saving for the cohort was £263,000 ($342,000). CONCLUSIONS: Algorithm-led preoperative anemia screening and management in elective arthroplasty was associated with reduced RBC transfusion, readmission, critical care admission, LOS, and costs.

Fascia iliaca compartment block for hip fractures: experience of integrating a new protocol across two hospital sites.

OBJECTIVE: Fascia iliaca compartment block (FICB) administered through the loss of resistance technique effectively reduces pain and opiate requirement in elderly patients with hip fractures. FICB is a simple technique and is easily taught. This paper plots the implementation of FICB in two hospitals. METHODS: A continuous audit process of two separate sites recorded the uptake of the FICB on an organizational level. An additional control group (CG) of 100 patients were analysed to compare pain scores (using the Numerical Rating Scale) and opiate requirements between groups of patients receiving fascia iliaca block and those receiving standard care. Documentation habits and adverse drug reactions were monitored over the audit process. RESULTS: There were 434 patients audited, with 326 (75.1%) receiving the FICB. The uptake of the FICB and documentation improved over time. The FICB significantly reduced pain scores (P<0.001) and also opiate requirement (P<0.0001) compared with those in the CG. Acute length of stay reduced to 9.9 days (FICB group) from 15 days (CG). Inpatient mortality was 5.5% in the FICB group and 15% in the CG (P=0.0024). CONCLUSION: Organizational learning of this simple procedure can be achieved through a multidisciplinary approach, and committed departmental education and feedback. The impact on length of stay and mortality were striking; however, there may be other confounding factors. Only two cases of true anaesthetic toxicity occurred in 1586 patients. The authors conclude that FICB is a safe procedure and a useful adjunct for preoperative pain control in patients with hip fractures.
