COVID-19 ICU Patient Tisdale Score Prevalence Ratios in Brasilia 2020

Natalia L. Freitas created this dataset analyzing the prevalence ratio of Tisdale scores for QT interval prolongation in COVID-19 ICU patients. The study covers patients admitted to a Brasilia reference hospital from March to December 2020. It includes metrics for systemic arterial hypertension (SAH), prevalence ratio (PR), and 95% confidence intervals.

Use Cases

• Analyze the prevalence ratio (PR) of Tisdale scores across patient cohorts to assess QT interval prolongation risk in COVID-19 ICU admissions.
• Examine the association between systemic arterial hypertension (SAH) status and Tisdale score prevalence ratios within the 2020 Brasilia patient population.
• Calculate 95% confidence intervals (95%CI) for prevalence ratios to evaluate the statistical significance of observed Tisdale score variations.

Strengths

• Focuses on a specific, clinically relevant population: COVID-19 patients admitted to an ICU in 2020.
• Includes key epidemiological metrics: prevalence ratio (PR) and 95% confidence interval (95%CI).
• Data is licensed under CC BY 4.0, permitting flexible reuse with attribution.

Limitations

• The dataset is very small at 5.5 KB, indicating a limited scope and likely a small patient sample size.
• No column definitions or sample data are available, making the exact data structure and variables unclear.
• Data is from a single reference hospital in Brasilia, limiting geographic generalizability.
