Search Strategy for Blood Transfusion Trials in Critical Care and Surgery

Search strategies for six major databases including MEDLINE, EMBASE, and Web of Science, focusing on randomized controlled trials for blood transfusion thresholds. The dataset was created by Daniela Ziegler, with an initial search conducted on March 27, 2024, and last updated on May 28, 2026. It was harvested from the Borealis Dataverse platform.

Use Cases

• Replicating or updating a systematic review based on the documented search strategies for six databases.
• Analyzing search term effectiveness for concepts like 'blood transfusion' and 'hemoglobin level' in medical literature.
• Training researchers on constructing comprehensive search strings for network meta-analyses of clinical trials.

Strengths

• Search strategies are documented for six major academic databases, including MEDLINE and EMBASE.
• Specific search concepts like 'randomized controlled trial' and 'meta-analysis' are clearly stated.
• The dataset has a clear timeline with an initial search date and a recent update in May 2026.

Limitations

• The actual data content (e.g., search results, extracted study data) is not described, only the search strategies.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
