Insights
Predicting Post-Acute Sequelae of COVID-19 (PASC) is crucial. Overweight/obesity, prior statin use, and respiratory symptoms during infection are key predictors. A composite risk score aids in identifying individuals at higher risk for PASC.
Area of Science:
- Medical research
- Public health
- Data science
Background:
- Post-Acute Sequelae of COVID-19 (PASC) present a significant global health challenge.
- Identifying predictive factors for PASC is essential for proactive healthcare management.
Purpose of the Study:
- To uncover predictive factors for PASC using multi-modal data.
- To develop and evaluate a predictive model for PASC diagnoses.
Main Methods:
- Analysis of electronic health records from 92,301 COVID-19 patients.
- Utilized a Super Learner-based prediction approach for factor identification.
- Integrated model outputs into individual and composite risk scores for performance evaluation.
Main Results:
- Identified overweight/obesity, pre-infection HMG CoA reductase inhibitor use, and respiratory symptoms during COVID-19 as predictive factors for PASC.
- Developed a composite risk score with moderate discriminatory ability (AUC: 0.66).
- The composite risk score identified 10% of individuals with a 2.2-fold increased risk for PASC.
Conclusions:
- Several factors predictive of PASC diagnoses were identified.
- A composite risk score was developed to aid in PASC prediction.
- This risk score can help identify high-risk individuals and inform preventive strategies.
Background:
Post-Acute Sequelae of COVID-19 (PASC) have emerged as a global public health and healthcare challenge. This study aimed to uncover predictive factors for PASC from multi-modal data to develop a predictive model for PASC diagnoses.
Methods:
We analyzed electronic health records from 92,301 COVID-19 patients, covering medical phenotypes, medications, and lab results. We used a Super Learner-based prediction approach to identify predictive factors. We integrated the model outputs into individual and composite risk scores and evaluated their predictive performance.
Results:
Our analysis identified several factors predictive of diagnoses of PASC, including being overweight/obese and the use of HMG CoA reductase inhibitors prior to COVID-19 infection, and respiratory system symptoms during COVID-19 infection. We developed a composite risk score with a moderate discriminatory ability for PASC (covariate-adjusted AUC (95% confidence interval): 0.66 (0.63, 0.69)) by combining the risk scores based on phenotype and medication records. The combined risk score could identify 10% of individuals with a 2.2-fold increased risk for PASC.
Conclusions:
We identified several factors predictive of diagnoses of PASC and integrated the information into a composite risk score for PASC prediction, which could contribute to the identification of individuals at higher risk for PASC and inform preventive efforts.
