The effect of an intraoperative treatment algorithm on physicians' transfusion practice in cardiac surgery

Background : Inappropriate transfusion in cardiac surgery may, in part, be due to empiric transfusion therapy instituted in the absence of timely laboratory data. Therefore, the effect of a transfusion decision algorithm based on intraoperative coagulation monitoring of physicians' transfusion practice and the transfusion outcome was evaluated. Study Design and Methods : In a randomized, controlled trial, cardiac surgical patients determined to have microvascular bleeding at the cessation of cardiopulmonary bypass were assigned to algorithm (A) or standard (S) therapy. Group A was treated with plasma and platelet therapy according to a transfusion algorithm based on on-site coagulation data available within 4 minutes. For Group S, the use of laboratory-based data and the decision to transfuse blood components were at physician discretion. Results : Sixty-six patients were entered into the study (Group A, n = 30; Group S, n = 36). Other than the fact that there were significantly more female patients in Group S than in Group A, no differences between cohorts in regard to perioperative risk factors for blood transfusion needs were identified. Therefore, gender was factored in as a covariate in the statistical analysis. Group A patients received fewer hemostatic blood component units (p = 0.008) and had fewer total donor exposures (p = 0.007) during the entire hospitalization period. Linear regression analysis of the differences in slopes in Groups A and S for the relationships between the red cell volume lost and the red cell volume transfused (p < 0.03), non-red cell units transfused (p < 0.0001), and total number of blood components transfused (p < 0.0001) demonstrated that physicians' transfusion practice was significantly altered by the use of a transfusion algorithm with on-site coagulation data, independent of surgical blood losses. Conclusion : The use of algorithms by transfusion decision makers can serve as an effective physician education intervention.     

The impact of psychosocial training on staff attitudes towards people living with dementia: A systematic review

Background

As the prevalence of dementia increases, the need for appropriately trained and skilled care teams also increases. Staff attitudes towards people living with dementia have a significant impact on caregiving behaviours and staff and resident outcomes. Training within care settings is a potential way of improving staff attitudes towards residents in their care.

Objectives

This review aimed to (i) assess the effectiveness of psychosocial training in improving care staff attitudes towards dementia; and (ii) examine the content and focus of training.

Method

The review was conducted following PRISMA guidance and the protocol was registered on PROSPERO prior to conducting the review. A comprehensive search of peer-reviewed literature was undertaken using CINAHL, Medline and PsycINFO from inception to March 2021. All papers were evaluated using a quality appraisal tool.

Results

Ten studies met inclusion criteria and were of variable quality. However, six studies found significant improvements in staff attitudes towards dementia following staff training. The studies varied in terms of training focus and included behavioural, communication and cognitive-based approaches.

Conclusions

Staff training could be an effective method of improving staff attitudes towards dementia in care settings. Further research adopting high-quality randomised controlled designs to further explore staff attitudes following psychosocial training would make a valuable contribution to the literature base.
