Trends in transfusion rates after the FOCUS trial

Area of Science:

• Transfusion Medicine
• Clinical Practice Guidelines
• Health Services Research

Background:

• The FOCUS trial established that routine blood transfusions for hip surgery patients with hemoglobin levels above 8 g/dL offer no additional benefit.
• Understanding the real-world impact of clinical trial findings on healthcare practices is crucial for optimizing patient care and resource allocation.

Purpose of the Study:

• To estimate the impact of the FOCUS trial findings on transfusion rates among hip surgery patients.
• To identify trends in transfusion practices following the dissemination of the FOCUS trial results.

Main Methods:

• Analysis of inpatient discharge data from four states to evaluate transfusion rate trends.
• Comparison of observed transfusion rates with projected rates based on pre-FOCUS trial trends.

Main Results:

• A significant decrease in transfusion rates was observed post-FOCUS trial, with a 5.2 percentage point reduction in the fourth quarter of 2013 compared to pre-trial trends.
• Hospitals with a lower treatment intensity index showed a more pronounced decline in transfusion rates, suggesting practice pattern variations.

Conclusions:

• The FOCUS trial has demonstrably influenced clinical practice regarding transfusion protocols for hip surgery patients.
• Despite the positive impact, further opportunities remain to optimize and reduce the overall use of blood transfusions in this patient population.
