Acute Kidney Injury in Neurocritical Patients at High Altitude, 2022-2024

390 adult neurocritical patients admitted to an ICU at 3,650 m altitude from January 2022 to February 2024 were analyzed. The dataset, authored by Quzhen Danzeng and shared under CC-BY-4.0, reports a 21.3% incidence of acute kidney injury (AKI) and identifies independent risk factors including age, BMI, Glasgow Coma Scale score, hypotension, and hemoglobin levels.

Use Cases

• Predicting AKI risk based on patient demographics and clinical markers described in the study.
• Analyzing the association between hemoglobin levels and renal outcomes in hypoxic conditions.
• Evaluating the impact of interventions like contrast agents and diuretics on AKI incidence using propensity score matching methodology.
• Studying the economic burden of AKI through reported hospitalization costs.

Strengths

• Dataset includes 390 patient records with a clearly defined outcome measure (AKI by KDIGO criteria).
• Analysis identifies 7 independent predictors with odds ratios and confidence intervals.
• Study design includes sensitivity analysis via propensity score matching.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects a single-center study at 3,650 m, which may limit generalizability.
