Background: Drug therapy during hospital stay has significant preventable risk for patients and should be optimised regarding drug safety [1]. Evidence-based information-need develops with growing numbers of diagnosis, older age patients and the chronicity of diseases.

Time for information retrieval during routine physician working hours in the hospital is scarce and centralised clinically trained personal can offer economic information retrieval.

Operating since 1992 the pharmacy-based drug information service of the university hospital of Munich (DIS) answered 19112 enquiries 2005-2014 for health care personnel, physicians, nursing staff, microbiology and others. All enquiries were answered according to quality standards including documentation [2].

Materials and Methods: Enquiries by physicians from 01.01.2005 to 31.12.2014 were extracted from the documentation system ADKA Arzneimittel-Info-Datenbank. Analysis included number of enquiries, enquirer department, urgency of enquiry, answering time and category of enquiry.

The category „Choice of drug“ was evaluated for complexity according to british standards [3]. Each answer in this category was screened for clinically relevant information included by pharmacists, which was not part of the enquiry.

Results: 9823 enquiries, i.e. 51% of all enquiries answered during 2005-2014 were asked by physicians. 49 departments of the university hospital asked enquiries. 4981 (50%) enquiries were asked by five departments: the pediatric dept. 2245 (45%), three internal medicine depts. 1941 (39%) and the psychiatric dept. 795 (16%).

2172 (22%) were from intensive care units, 2181 (22%) from pediatric units and 5470 (56%) from general wards.

6564 (67%) enquiries needed an answer immediately or on the same day.

The average answering time was 71 min in 2005 and 45 min in 2014.

Top five categories: Drug-drug-interactions 1554 (16%), Choice of drug 1494 (15%), Adverse drug reactions 1068 (11%), Drug Dosage 1001 (10%), Drug administration 798 (8%)

Complexity level in „Choice of drug“: Level 1 (simple enquiries or data) 533 (36%); Level 2 (complex enquiries – multiple sources) 404 (27%); Level 3 (complex enquiries – professional judgement) 557 (37%)

In 246 (17%) answers the pharmacist added additional clinically relevant information f.e. galenics, PK/PD, incompatibility data (parenteral drug therapy) or alert for adverse drug reaction report.

Conclusion: The DIS ist used frequently by physicians. Most of the enquiries related to drug choice needed complex research strategies and professional judgement. Answering time becomes shorter by using documented answers as bottom level for actual answers.

Adding pharmaceutical drug therapy knowledge might improve patient safety.

The DIS offers the advantage of using interprofessional communication potential directly to optimise patient care.
