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.
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.
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 < 0.001) min higher for queries for which there was a lack of documentation and 139 (95 % CI 74 to 203, p < 0.001) min higher when conflicting information was present in the literature. Staff members with less than 1 year of experience consumed a mean of 91 more minutes (95 % CI 32 to 150, p = 0.003) per query than staff members with more than 2 years of experience.
This study demonstrates the large variation in time consumed answering queries posed to Scandinavian DICs. The results highlight the need for highly competent staff members and easy access to drug information sources. Further studies are required to explore the association between time consumption and response quality.
关于药物信息中心（DICs）提供的服务，基于研究的文献资料较少。这项多中心研究的目的是首次探索在八个不同但具有可比性的DICs回答药物相关问题时与时间消耗相关的因素。
在为期8周的时间里，八个斯堪的纳维亚DICs的工作人员记录了他们回答问题所用的分钟数。采用混合模型线性回归分析来探索回答问题时与时间消耗相关的因素。
每个问题的平均时间消耗为178分钟（范围为4 - 2540分钟）。对于缺乏文献记录的问题，每个问题的平均时间消耗增加28分钟（95%置信区间（CI）为23至33，p < 0.001）；当文献中存在相互矛盾的信息时，平均时间消耗增加139分钟（95% CI为74至203，p < 0.001）。经验少于1年的工作人员每个问题的平均时间消耗比经验超过2年的工作人员多91分钟（95% CI为32至150，p = 0.003）。
本研究表明，回答斯堪的纳维亚DICs提出的问题所消耗的时间差异很大。结果突出了对高素质工作人员的需求以及方便获取药物信息来源的必要性。需要进一步研究来探索时间消耗与回答质量之间的关联。
