Quality assurance in melanoma care: guideline-based quality indicators for melanoma - implementation, evaluation and update process.

Background: In 2018, an update of the German evidence-based (S3) guidelines "Diagnosis, Therapy and Follow-up of Melanoma" first issued in 2013 was published under the auspices of the German Guideline Program in Oncology. The update also included a revision of existing guideline-based quality indicators (QIs).

Patients And Methods: Using a standardized multi-step process, the guideline-derived QIs were revised by a multidisciplinary, interprofessional working group based on the strong (level A) recommendations contained in the guideline update as well as on a systematic literature search for international indicators and on the outcomes of existing QIs as reported by certified German skin cancer centers.

Results: Based on the original set of twelve guideline-based QIs agreed upon in 2013, the working group developed an updated set containing nine indicators. Four QIs were kept unchanged; two were modified; two were removed; and three new QIs were added. Unlike 2013, the working group was now able to incorporate the outcomes of QIs previously implemented at the various skin cancer centers.

Conclusions: Close cooperation between guideline group and certification commission allows for the implementation of guideline-based QIs in cancer care. Measured outcomes form the basis for updating both the guidelines and the QI development process. They provide information about the care of cancer patients in a real-world setting as well as on guideline adherence and the feasibility of QIs themselves. This is a dynamic process that can be described in a transparent manner and that requires regular updating.
