What is the ePBI-K?


The ePBI-K is an instrument for patients with skin irritations and their physicians based on the Patient Benefit Index (PBI).


The PBI-K was specially developed for patients with skin irritations or non-symptomatic courses of dermatological skin diseases, such as atopic dermatitis. It helps patients to set treatment goals and to monitor the fulfillment of these goals afterwards. It can also be used for quality assurance and shared decision making. The ePBI is available as a mobile application for Android and iOS devices and as a web-based online tool.

Assessing the ePBI-K

Before treatment the patient completes the Patient Needs Questionnaire (PNQ) and after starting a treatment - the Patient Benefit Questionnaire (PBQ). A score is then assigned to each answer with which the final index (PBI) can be calculated.

The index range is between 0 (no patient relevant benefit) and 4 (maximum patient relevant benefit).

Endpoint Model: Treatment of Disease X

About Patient Reported Outcomes


“A PRO is any report of the status of a patient’s health condition that comes directly from the patient, without interpretation of the patient’s response by a clinician or anyone else.”


“Use of a PRO instrument is advised when measuring a concept best known by the patient or best measured from the patient perspective. […] PRO instrument adequacy depends on its role and relationships with other clinical trial endpoints as depicted in the endpoint model.”
