What is the ePBI-W?

The ePBI-W is used to set goals and evaluate the degree of achievement for patients with chronic wounds and their physicians based on the Patient Benefit Index (PBI).

The PBI-W was specifically developed for patients with chronic wounds. It helps patients to set treatment goals and to monitor their achievement after therapy or over time. It can also be used for quality assurance purposes and shared decision-making. The ePBI-W is available as a mobile application for Android and iOS devices and as a web-based online tool.

Validation of questionnaire

paper version: yes digital version: yes

Before the beginning of treatment, the patient completes a questionnaire on their treatment goals (PNQ: Patient Needs Questionnaire) and indicates how important these are to them on a 5-point scale from "not at all" to "very" or whether they do not apply to them. After starting treatment, the patient completes the Patient Benefit Questionnaire (PBQ) and indicates the extent to which the treatment has helped them to achieve the previously listed goals or whether these did not apply to them. Once again, this is rated on a 5-point scale from "not at all" to "very". Finally, the overall benefit of the therapy is calculated from the answers given.

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.”
