The Candida score calculator is a tool designed to assess the risk of developing invasive candidiasis based on four specific medical conditions. By evaluating these factors, the calculator assigns a numerical score and provides an interpretation of the associated risk.

Inputs:
- Surgery: This asks whether the patient has undergone surgery, rated as either True or False.
- Multifocal Candida Colonization: This checks if there is colonization in multiple sites, rated as True or False.
- Total Parenteral Nutrition: This inquires whether the patient is receiving total parenteral nutrition, rated as True or False.
- Severe Sepsis: This asks if the patient is experiencing severe sepsis, rated as True or False.

Each factor is evaluated and assigned a score:
- Surgery, Multifocal Candida Colonization, and Total Parenteral Nutrition contribute 1 point each if the answer is True, and 0 points if the answer is False.
- Severe Sepsis contributes 2 points if True, and 0 if False.

The score is calculated by summing the points from each factor. Here is how each input contributes to the score:

| Input                          | Score if True | Score if False |
|-------------------------------|---------------|----------------|
| Surgery                       | 1             | 0              |
| Multifocal Candida Colonization | 1             | 0              |
| Total Parenteral Nutrition    | 1             | 0              |
| Severe Sepsis                 | 2             | 0              |

Based on the calculated score, the interpretation of the risk of invasive candidiasis is as follows:
- A total score of less than 3 indicates a 2.3% risk of invasive candidiasis.
- A score of exactly 3 suggests an increased risk of 8.5%.
- A score of 4 indicates a further elevated risk of 16.8%.
- A maximum score of 5 reflects the highest risk level at 23.6%.

These interpretations provide an understanding of how the presence of these clinical conditions relates to the likelihood of developing invasive candidiasis, with higher scores correlating with greater risk.

The Candida Score is a clinical calculator used in the intensive care unit (ICU) setting to predict the likelihood of invasive candidiasis in critically ill patients. This scoring system is particularly useful in guiding antifungal treatment decisions in ICU patients. The score is calculated based on four variables: total parenteral nutrition, surgery, multifocal Candida colonization, and severe sepsis. Each variable is assigned a certain number of points, and a total score of 3 or more suggests a high probability of invasive candidiasis. The Candida Score is not applicable to patients outside of the ICU or those without risk factors for invasive candidiasis.
