Frequency of use and annual costs of biological therapy for psoriasis in Colombia in 2019

Background: Evidence describing the types and annual costs of biological treatments for psoriasis in Latin America is scarce. This study aimed to estimate the frequency of use and costs of biologic therapy for psoriasis in Colombia in 2019. Methods: This secondary data analysis uses the International Classification of Diseases terms associated with psoriasis, excluding those related to psoriatic arthritis, based on data from the registry of the Colombian Ministry of Health. We estimated the prevalence of psoriasis per 100,000 inhabitants; then, we retrieved the frequency of use of biologic therapy in patients with psoriasis and estimated the cost per year of each and overall therapies in 2019 in US dollars (USD). Results: There were 100,823 patients with psoriasis in Colombia in 2019, which amounts to a prevalence of 0.2% in the general population. Of those patients, 4.9% received biologic therapy, most frequently males (60%). The most commonly used biological therapies for psoriasis in Colombia in 2019 were ustekinumab (35.2%), with an annual cost per patient of $12,880 USD; adalimumab (26%), with a yearly cost per patient of $7130 USD; and secukinumab (19.8%), with an annual cost per patient of $6825 USD. Conclusion: This is the first study to describe the use and cost of biological therapy for psoriasis in Colombia. It provides valuable cost-awareness information for the Colombian health system.
