Qualitative investigation of disease course, characteristics and lived experience of generalized pustular psoriasis

BACKGROUND: Generalized pustular psoriasis (GPP) is a relapsing-remitting chronic disease characterized by painful pustules with systemic symptoms that negatively impacts quality of life. The psychosocial and economic burden of this rare condition is not well characterized.

OBJECTIVES: To qualitatively characterize the cumulative burden of generalized pustular psoriasis on patients' quality of life and psychosocial wellbeing.

METHODS: A retrospective chart review of patients with generalized pustular psoriasis was performed to collect demographic information, followed by prospective semi-structured clinical interviews. Interview transcripts were analyzed using thematic analysis.

RESULTS: Three major themes were revealed: (1) Burden of having a chronic disease with an unpredictable course, (2) an inability to fulfill societal roles results in a loss of identity, and (3) a physician-patient relationship grounded in trust and transparency can be invaluable in helping patients endure chronic disease.

CONCLUSION: GPP has a negative impact on patients' quality of life and psychosocial wellbeing. Impairments in daily function and mental health primarily affects patients during flares and influences behavior during periods of quiescence. A strong patient-physician relationship may help mitigate the impact of GPP.
