View source for High speed clinical data retrieval system with event time sequence feature: with 10 years of clinical data of Hamamatsu University Hospital CPOE

This is a review of an article by Kimura et al, ''Creating High speed clinical data retrieval system with event time sequence feature: with 10 years of clinical data of Hamamatsu University Hospital [[CPOE|CPOE]]'' <ref name="Kimura-2008> Kimura, M., Tani, S., Watanabe, H., Naito, Y., Sakusabe, T., Nakaya, J., ... & Furuta, T. (2008). High speed clinical data retrieval system with event time sequence feature. Methods of information in medicine, 47(6), 560-568. http://www.ncbi.nlm.nih.gov/pubmed/19023490. </ref>

== Objective ==
To implement a high speed data retrieval system for hospital information accumulated in 10 years for the purpose of research, evidence creation and patient safety. 

== Methods ==
Lab results, prescription and injection orders, disease diagnoses, and patients' demographics are exported from Hospital Information System in [[HL7|HL7]] format. A hierarchical variable length data structure using [[MUMPS]] is used to store data. A total of 73, 709, 298 records is available for searching.

== Results ==
The data retrieval system D*D provides fast retrieval to end user. Simple retrieval takes about 2 seconds. Complex retrievals take around 2 minutes allowing Boolean operations. Average monthly access of the D*D system averages 703 searches. The whole system does not affect routine operation of existing CPOE system.

== Conclusion ==
Using exported data from CPOE, the new system is proved to provide excellent search environment with high speed.
 
== Comments ==
This paper introduced the D*D system for fast retrieval of CPOE system. The strategy that data was first exported from CPOE and then independently accessed from a cache database has its benefits of not interrupting routine CPOE usage. However, it may not always get the most current data since all data indexed is staged, not real time.
