Using ADCT in clinical practice

Atopic Dermatitis Control Tool (ADCT) has been validated for use in adult and adolescent patients (12 years and older) with atopic dermatitis.

To use ADCT correctly, a patient must answer all six ADCT questions by selecting the most appropriate answer.

ATOPIC DERMATITS CONTROL TOOL (ADCT)

Please answer the following questions thinking about your experiences with eczema, sometimes called “atopic dermatitis”.

Calculating the ADCT score

Step 1: Each ADCT question is scored 0–4 points, as shown in the table above

Step 2: The sum of the scores from all six ADCT questions forms the ADCT total score

The minimum ADCT total score is 0, the maximum ADCT total score is 24

Interpreting the ADCT total score

Point‐in‐time control status
A higher score indicates lower atopic dermatitis control

A patient’s atopic dermatitis may not be well controlled if:

  • The ADCT total score is at least 7 points

or

  • One of the patient’s answers falls into the blue boxed area in the ADCT table above
Changes in control status over time
A change of 5 points is the threshold for meaningful within person change
  • Decrease of 5 points or more: indication of clinically relevant improvement of atopic dermatitis control
  • Increase of 5 points or more: indication of clinically relevant worsening of atopic dermatitis control

Engaging patients in a meaningful conversation about their perception of atopic dermatitis control across multiple domains

A patient’s atopic dermatitis may not be adequately controlled if:

  • Their ADCT total score is at least 7 points

or

  • One of their answers falls in a blue coloured box in the ADCT table above

or

  • Their ADCT total score increases by 5 points or more since they last used ADCT

ADCT can be used to detect change over time supporting a patient-physician conversation on sustained control in clinical practice.
