1. What is the HCT CI Score?

The HCT CI (Hematopoietic Cell Transplantation Comorbidity Index) score is a tool used to assess comorbidity burden in patients undergoing hematopoietic cell transplantation. It helps predict non-relapse mortality and overall survival outcomes.

2. How Does the Calculator Work?

The calculator uses the HCT CI formula:

Where:

• \( scores \) — Individual comorbidity scores (unitless)

Explanation: The equation sums individual comorbidity scores to calculate the total CI score, which represents the overall comorbidity burden.

3. Importance of CI Score Calculation

Details: Accurate CI score calculation is crucial for risk stratification in transplant patients, helping clinicians make informed decisions about treatment suitability and intensity.

4. Using the Calculator

Tips: Enter individual comorbidity scores separated by commas. All values should be valid numerical scores.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of HCT CI scores?
A: Scores typically range from 0 to 10+, with higher scores indicating greater comorbidity burden.

Q2: How is the CI score interpreted?
A: Higher scores correlate with increased risk of non-relapse mortality and decreased overall survival after transplantation.

Q3: What comorbidities are included in the scoring?
A: The index includes various conditions such as cardiac, pulmonary, hepatic, renal diseases, and prior malignancies.

Q4: Are there limitations to this scoring system?
A: The score may not capture all relevant comorbidities and should be used alongside clinical judgment and other prognostic factors.

Q5: How often should the CI score be reassessed?
A: The score should be reassessed if the patient's comorbidity status changes significantly before transplantation.
