title: Physician's expectations regarding prescribing clinical decision support systems in a Belgian hospital.
abstract: OBJECTIVE
  Developing and implementing clinical decision support systems (CDSSs) is time-consuming and costly. Therefore, prioritization of the most relevant systems is warranted. The physician's perceived usefulness has been identified as a decisive reason for using CDSSs. The objective of this study was to investigate the physician's perceived usefulness of different types of CDSSs and to identify the user needs and expectations regarding future CDSSs.
  
  
  METHODS
  Cross-sectional single-centre survey among physicians with a clinical assignment in a university hospital. Physicians were questioned about their current experiences with drug prescribing and the perceived usefulness and desired features of future CDSSs.
  
  
  RESULTS
  One hundred and sixty-four physicians completed the survey (52·6%). The majority acknowledged that it is very difficult to take all relevant information into account when prescribing drugs. Drug-drug interaction checking, drug-allergy checking, and dosing guidance were considered as most useful. Automated clinical guidelines and adverse drug event monitoring were considered as least useful. The user-friendliness of the systems, clinical relevance of the alerts, and prevention of alert fatigue were perceived as important aspects for a successful implementation.
  
  
  CONCLUSIONS
  From the physicians' perspective drug-drug interaction checking, drug-allergy checking, and dosing guidance should receive the highest priority for development and implementation. Because the perceived usefulness has been identified as a decisive reason for using CDSSs, it seems feasible to take into account this prioritization when developing and implementing CDSSs. In order to overcome the physicians' perceived disadvantages, attention should go to the development of user-friendly systems that deliver clinical relevant alerts.
