Abstract
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.
