• Clinicians can utilize the app to inform clinical decisions by understanding the risk profile of patients with multiple comorbidities.
• Researchers may use the app for cohort studies involving the analysis of patient outcomes based on comorbidity burdens.
• Healthcare administrators can assess the risk stratification of patient populations to allocate resources effectively.

• The CCI Calculator App relies on accurate data entry. Misclassification of comorbidities may lead to incorrect risk estimations.
• Although the app doesn’t store any patient data, users should not upload identifying/sensitive information.
• The CCI provides a general estimate and may not fully capture the nuances of individual patient scenarios.
• The tool is based on data and weightings that may not reflect the latest clinical evidence or account for local demographic differences.

• The Charlson Comorbidity Index is validated by numerous studies and is recognized as a standard tool for risk adjustment in hospital outcome studies.
• It has been extensively used in clinical research and has undergone several updates to reflect changing clinical understandings.

I’m Dan Caron, the founder of Health Universe and the owner of this app. I founded it with the intent to democratize health AI/machine learning, and it hosts a wide collection of high-quality models that are useful for clinicians, patients, and researchers. I created this app to facilitate a quicker, more accessible method for calculating the CCI, which is often done manually.
