The effect of the introduction of Picture Archiving and Communication System on interpretation rate of radiologic examinations / 대한의료정보학회지

OBJECTIVE: This study was designed to evaluate the effect of the introduction of picture archiving and communication system(PACS) by identifying the change of the interpretation rates of radiologic examinations. METHODS: The data about total of 297,314 radiologic examinations done from June, 2001 to June 2002 was collected through medical record. December, 2001 which was the month of PACS introduction was excluded from the analysis for controlling the bias. Data concerning the time spent on interpretation, types of patients, clinical departments and types of radiologic examinations were collected. Chi-square test was performed to evaluate differences before and after introduction of PACS. RESULTS: 1. The interpretation rates of total radiologic examinations significantly increased after the introduction of PACS. The interpretation rate within 1 day increased 2.3 times higher after the introduction of PACS. 2. Both of the interpretation rates of radiologic examinations for outpatients and inpatients were significantly increased after the introduction of PACS. The interpretation rate within 1 day of radiologic examinations among outpatients increased 2.1 times higher and that among inpatients increased 3 times higher after the introducton of PACS. CONCLUSION: There was overall increase of interpretation rate suggesting the improvement of performance in department of radiology. This indicated that introduction of PACS brought about a positive impact on medical service quality through improving operational efficiency.

A development of Entity-Relationship Model on Computer Based Patient Record / 대한의료정보학회지

The purpose of this study presents the model of Entity-Relationship Diagram on CPR. The specific purpose of this study as follows; The first goal is to identify the content and logical structure of the CPR. The second goal is to define the relationship of data coming from diverse systems(for example, clinical laboratory information systems, order entry systems) and the data stored in the CPR. The 22 kinds forms on Medical Record were collected from 10 hospitals. The Clinical heart of the CPR is the core of entities: patient, provider, problem, encounter order, service, history, etc.
