The impact of an integrated hospital-community medical information system on quality and service utilization in hospital departments.
OBJECTIVE
In 2005, an innovative system of hospital-community on-line medical records (OFEK) was implemented at Clalit Health Services (CHS). The goals of the study were to examine the extent of OFEK's use and its impact on quality indicators and medical-service utilization in Internal Medicine and General Surgery wards of CHS hospitals.


METHODS
Examining the frequency of OFEK's use with its own track-log data; comparing, "before" and "after", quality indicators and service utilization data in experimental (CHS patients) versus control groups (other patients).


RESULTS
OFEK's use increased by tens of percentages each year, Internal Medicine wards showed a significant decrease in the number of laboratory tests and 3 CT tests performed compared with the control group. Wards using OFEK extensively showed a greater decrease in CT tests, in one imaging test, and in the average number of ambulatory hospitalizations. No similar changes were found in General Surgery wards.


CONCLUSIONS
The study helps evaluate the extent to which OFEK's targets were achieved and contributes to the development of measures to examine the impact of such systems, which can be used to assess a broad range of Health Information Technology (HIT) systems.
