How to use the eNAPPA
The NAPPA-QOL and NAPPA-PBI questionnaires are filled in by the patient himself. The questionnaire is self-explanatory; yet, patients can be supported if they are not able to fill it in by themselves.The NAPPA-CLIN is filled by the dermatologist or assisting persons. This part needs a basic understanding of clinical signs at the nails.
The three components (modules) have been developed and validated on an international basis. Thus, several language versions are available. The modules can be used independently from each other.
The impact of nail psoriasis
More than 50% of moderate to severe psoriasis patients have nail involvement which in many cases causes functional and emotional impairment and can be painful. Measurement of patient-related outcomes is essential for research and clinical care.
