1. What is the HCT Comorbidity Index?

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

2. How Does the Calculator Work?

The calculator uses the HCT-CI equation:

Where:

• \( scores \) — Sum of individual comorbidity scores (unitless)

Explanation: The index sums weighted scores from various comorbidities to provide an overall assessment of a patient's health status prior to transplantation.

3. Importance of HCT-CI Calculation

Details: Accurate HCT-CI assessment is crucial for risk stratification, treatment planning, and predicting outcomes in patients undergoing hematopoietic cell transplantation.

4. Using the Calculator

Tips: Enter the sum of comorbidity scores. The value must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What comorbidities are included in HCT-CI?
A: The index includes various conditions such as cardiac, pulmonary, hepatic, renal diseases, infections, and other significant medical conditions.

Q2: What are typical HCT-CI score ranges?
A: Scores typically range from 0 to 10+, with higher scores indicating greater comorbidity burden and higher risk.

Q3: How is HCT-CI used clinically?
A: It helps clinicians assess transplant eligibility, predict outcomes, and tailor conditioning regimens and supportive care.

Q4: Are there limitations to this index?
A: The index may not capture all relevant comorbidities and should be used in conjunction with clinical judgment and other assessment tools.

Q5: How often should HCT-CI be assessed?
A: It should be assessed at initial transplant evaluation and may be re-evaluated if significant changes in health status occur.
