Official title
A Predictive Tool for Predicting Adverse Outcomes in Acute Pulmonary Embolism Patients Using Parameters Obtained by Computed Tomographic Pulmonary Angiography.
Overview
This study collected clinical, laboratory, and CT parameters of acute patients with acute pulmonary embolism from admission to predict adverse outcomes within 30 days after admission into hospital.
Detailed description
This study collected clinical, laboratory, and CT parameters of acute patients with acute pulmonary embolism from admission. The outcomes of interest were defined as the occurrence of adverse outcomes within 30 days after admission into hospital.
Eligible patients were randomized in some ratio into derivation and validation cohorts. The derivation cohort was used to develop and evaluate a multivariable logistic regression model for predicting the outcomes of interest. The discriminatory power was evaluated by comparing the nomogram to the established risk stratification systems. The consistency of the nomogram was evaluated using the validation cohort.
Primary outcome measures
- Adverse outcomes [Time frame: 7 days and 30 days]
Eligibility criteria
Inclusion criteria
