Practical Anemia Bundle and Hemoglobin Recovery in Critical Illness: A Randomized Clinical Trial

Area of Science:

• Critical Care Medicine
• Hematology
• Clinical Trials

Background:

• Anemia is a frequent complication of surgery and acute illness, linked to poor clinical outcomes.
• Effective anemia prevention and treatment strategies in critically ill patients require further investigation.

Purpose of the Study:

• To assess the impact of a multifaceted anemia management bundle compared to standard care.
• To evaluate effects on posthospitalization hemoglobin recovery and functional outcomes in acute illness survivors.

Main Methods:

• A parallel-group randomized clinical trial involving critically ill adults with moderate to severe anemia.
• Intervention group received an anemia management bundle (optimized phlebotomy, decision support, IV iron).
• Standard care group received conventional treatment.

Main Results:

• 100 patients were enrolled; 49 received the intervention, 51 received standard care.
• Patients in the intervention group showed significantly higher hemoglobin concentrations at 1 month post-discharge (adjusted mean difference, 0.69 g/dL; P=.02).
• The anemia management bundle was feasible and well-tolerated.

Conclusions:

• A multifaceted anemia management bundle effectively improved hemoglobin levels in critically ill adults post-hospitalization.
• This approach demonstrates feasibility and tolerability, suggesting potential for future clinical practice.
• Findings support the design of larger trials to confirm these benefits.
