MD Anderson Dysphagia Inventory (MDADI) Calculator
This calculator follows the MDADI structure developed at MD Anderson Cancer Center. Enter item values from 1 to 5 (higher values indicate better swallowing-related quality of life).
Educational use only. This tool does not diagnose disease and does not replace clinician scoring or treatment advice.
Emotional Domain (6 items)
Functional Domain (5 items)
Physical Domain (8 items)
What is this MD Anderson calculator?
When people search for an md anderson calculator, they are often looking for tools related to symptom burden, quality of life, or cancer-care follow-up measures developed at The University of Texas MD Anderson Cancer Center. This page focuses on one of the most commonly referenced frameworks: the MD Anderson Dysphagia Inventory (MDADI).
MDADI is used to quantify how swallowing problems affect daily life. It is especially common in head and neck oncology settings, survivorship clinics, speech-language pathology, and research studies that track functional outcomes over time.
How this calculator works
The form above uses the standard MDADI domain structure:
- 1 Global item
- 6 Emotional items
- 5 Functional items
- 8 Physical items
Each item is entered on a 1 to 5 scale. Higher values represent better swallowing-related quality of life.
Scoring Formula
- Domain score = (average of items in domain) × 20
- Composite score = (average of all 19 non-global items) × 20
- Global transformed score = global item × 20
The transformed scale ranges from 20 to 100, where higher scores indicate better function and less perceived impact.
How to use the results
1) Track trends, not just one number
A single score is useful, but serial measurements are more informative. For example, comparing pre-treatment, post-treatment, and long-term follow-up can reveal meaningful recovery trajectories.
2) Compare domain patterns
Two patients can have the same composite score but very different lived experiences. A lower emotional domain may suggest anxiety, social withdrawal, or reduced confidence around meals, while a lower physical domain may highlight direct swallowing symptoms.
3) Integrate with clinical context
Scores are not a stand-alone diagnosis. Clinicians typically interpret them alongside swallowing studies, nutrition data, treatment history, and direct examination findings.
Practical interpretation bands
There is no universal cutoff that applies to every population, but many teams use practical bands for quick review:
- 80-100: Mild or minimal impact
- 60-79: Moderate impact
- 40-59: High impact
- 20-39: Severe impact
These ranges are best used as a communication aid, not as strict diagnostic thresholds.
Frequently asked questions
Is this calculator official?
This page is an educational implementation of the MDADI-style scoring logic. For official clinical workflows, use your institution's approved forms and validation standards.
Can I use it for research?
You can use it for learning and preliminary checks. For formal research, ensure your team follows protocol-approved instruments, scoring rules, licensing requirements, and data-governance policies.
Does a low score mean recurrence or treatment failure?
Not by itself. A low score indicates higher patient-reported swallowing burden. It should trigger deeper assessment, not conclusions.
