Caracterización de estudios sobre calidad de vida relacionada con la salud en personas con psoriasis: Revisión sistemática 2003-2013

Abstract

Background: Psoriasis is a chronic skin disease that mainly affects the adult population and negatively affects the health-related quality of life (HRQoL). Objective: To characterize the studies on HRQoL in people with psoriasis, 2003-2013. Methods: Systematic review of the literature. We applied a research protocol with search terms, inclusion and exclusion criteria, and quality assessment of articles, by two researchers to ensure the completeness and reproducibility. The analysis was based on proportions, absolute frequencies, and the confidence intervals for proportions. Results: The initial search identified 8684 studies, out of which 220 met the protocol established. Europe and North America accounted for the largest number of publications in HRQoL in people with psoriasis (86.4%), with 43.2% of studies seeking health profiles or HRQoL, and 46.8% to measure the impact of a therapeutic action on HRQoL. The measurement tools most used to study HRQoL in this group are the DLQI (Dermatology Life Quality Index) and SF-36. The largest proportion of studies did not show the severity state, and among the studies that did show it, the most common form was psoriasis vulgaris. Conclusion: Despite the high prevalence of psoriasis in the world, few countries have published studies of the impact on HRQoL. The results found here demonstrate the importance and the need for the implementation of valid and reliable HRQOL measurement tools that can transcend traditional measurements of morbidity and disability, particularly in countries of America, where the development of research on this topic is scarce. © 2013 Asociación Colombiana de Reumatología.
