Factors associated with time consumption when answering drug-related queries to Scandinavian drug information centres: a multi-centre study

Purpose There is little research-based documentation on the services provided by drug information centres (DICs). The aim of this multi-centre study was to explore for the first time the factors associated with time consumption when answering drug-related queries at eight different but comparable DICs. Methods During an 8-week period, staff members at eight Scandinavian DICs recorded the number of minutes during which they responded to queries. Mixed model linear regression analyses were used to explore the factors associated with time consumption when answering queries. Results The mean time consumption per query was 178 min (range 4–2540 min). The mean time consumed per query increased by 28 (95 % confidence interval (CI) 23 to 33, p
