Background
and Aim: Evidence Based Medicine (EBM) is the explicit use of current best
evidence in making decisions about the care of individual patients. Hospital information system (HIS) can act as a
bridge between medical data and medical knowledge through merging of patient's
data, individual clinical knowledge and external evidences .The aim of this
research was to determine the Capability to establish EBM by HIS.
Materials
and Methods: This descriptive cross-sectional study was carried out on HISs of 30
hospitals from March to October 2011. Data were collected using a researcher-
constructed checklist including applicant’s background information as well as
information based on research objectives. Validity of the checklist were
assessed by the qualified specialists and then the data were analyzed using
descriptive statistics and SPSS software.
Results: HISs lacked the essential components for providing access to CDSS,
Reference databases and internet-based health information in 19, 16 and 20
hospitals were 63.3%, 53.3% and 66.7%, respectively. Twenty-two hospitals (70%)
had more than two-thirds of the essential components to access clinical and
administrative data repositories 23 hospitals (76.7%) had at least one
essential component to access contextual and case specific information.
Conclusion: The Capability of HIS is better in order to place EBM in
having access to the clinical and administrator data repositories while it
needs more attention in other areas.
