Blog - Indirect costs in psoriasis - Evidence Map

Published: 04-12-2017

We searched the heoro.com database to identify studies reporting the  indirect costs associated with psoriasis and psoriatic arthritis,  and the geographical settings in which these studies were conducted. We ran the search from 1960 to 1st June 2017 and analysed the abstracts identified by the search to determine the range of geographical locations, disease types,  interventions and study methodologies. We presented the findings as an evidence map.

We found a total of 57 abstracts. Of these, 14 reported indirect costs, including productivity losses, from the USA, 6 from Germany, 5 each from Italy and the UK, 3 each from Canada and the Netherlands, and 8 were reviews of the international literature.
