Living with Pyoderma Gangrenosum: A Qualitative Study.

Abstract

Pyoderma gangrenosum is a rare, autoinflammatory disorder characterized by rapidly progressive painful ulcers that are challenging to diagnose and treat. This qualitative study aimed to explore the experiences of patients living with pyoderma gangrenosum. Using an inductive qualitative approach, semi-structured interviews were completed with a purposive sample of 21 patients with pyoderma gangrenosum recruited from a public dermatology outpatient clinic in Melbourne, Australia. A reflexive thematic analysis was performed, yielding 5 themes: pain, physical challenges, social functioning and relationships, mental health, and treatment. The impact of pyoderma gangrenosum on quality of life was multifaceted and varied throughout disease progression, remission, and recurrence. Experiences of delayed diagnosis and misdiagnosis were common, causing distress and resulting in unnecessary treatments including surgery. Severe pain disrupted sleep and limited daily activities, eroding patients' sense of self-control and perpetuating depressed mood and anxiety. Management should include early specialist referral, providing information sheets for managing pain and wound care, and communicating disease expectations. In conclusion, this study has deepened understanding and given personal perspectives on what it is like to live with a condition poorly understood by many health professionals. Increased efforts should be made to increase clinician awareness regarding pyoderma gangrenosum to facilitate early diagnosis.
