The purpose of this study was to determine if the size of ultrasound examinations was increasing over time. The primary reasons for this are believed to be an increased number of images per study, the incorporation of "cine loops", and increased use of color flow Doppler. The result of this study, if it supports the hypothesis that ultrasound study size is increasing, would be directly applicable to planning for future expansion of storage in the Ultrasound PACS. Data were obtained from the ultrasound PACS server for number of studies, number of images, and total stored volume for sampled months (January and July of 2003 - 2006). The investigators believed that these months would provide a reasonable sample of study size as examination types did not vary significantly from month to month (based on Departmental statistics). The Radiology Department's information system (RIS) was used to determine total yearly ultrasound examination volume to determine the trend over time. Because no protected health information (PHI) was to be used in this study, the investigators believed that no IRB approval was necessary. The number of studies done per month was more variable than the investigators had believed. One month in particular (July, 2003) had an anomalously large number of studies. However, despite this, computations of the number of images per study, the total data volume per study, and the average amount of data per image did show an increasing trend as expected. Also, the total volume of data stored showed an increasing trend over the study time period. The investigators' hypothesis that examination size is increasing has been demonstrated to be true for the months sampled. From Departmental data, the investigators know that the most recent ultrasound yearly volume increased approximately ten percent over the previous year, and that trend was also seen for the study period (from 7-10 percent per year increase in volume). With the information that the examination size is also increasing, the Department can make better plans for future expansion of the Ultrasound PACS storage system. Ultrasound examination size is increasing, largely because of the increased use of cine loops. A change to using more of these to replace single static images will further increase examination size.

Read Abstract +

Our purpose was to determine the economic effects associated with the introduction of PACS and computed radiology (CR) in a medical intensive care unit (MICU). Clinical and financial data were collected over a period of 6 months, both before and after the introduction of PACS/CR in our medical intensive care unit. Administrative claims data resulting from the MICU stay of each patient enrolled in our study were transferred online to our research database from the administrative databases of our hospital and its affiliated clinical practices. These data included all charge entries, sociodemographic data, admissions/discharge/transfer chronologies, ICD9 diagnostic and procedure codes, and diagnostic related groups. APACHE III scores and other case mix adjusters were computed from the diagnostic codes, and from the contemporaneous medical record. Departmental charge to cost ratios and the Medicare Resource-Based Relative Value Scale fee schedule were used to estimate costs from hospital and professional charges. Data were analyzed using both the patient and the exam as the unit of analysis. Univariate analyses by patient show that patients enrolled during the PACS periods were similar to those enrolled during the Film periods in age, sex, APACHE III score, and other measures of case mix. No significant differences in unadjusted median length of stay between the two Film and two PACS periods were detected. Likewise, no significant differences in unadjusted total hospital and professional costs were found between the Film and PACS periods. In our univariate analyses by exam, we focused on the subgroup of exams that had triggered primary clinical actions in any period. Those action-triggering exams were divided into two groups according to whether the referring clinician elected to obtain imaging results from the workstation or from the usual channels. Patients whose imaging results were obtain from the workstation had significantly lower professional costs in the 7 days following the action-triggering exam compared with patients whose exam information was obtained through the usual channels. No significant differences in patient age or APACHE score were noted between these two groups. Our preliminary results show possible evidence of a reduction in unadjusted cost of care for the subgroup of patients whose action-triggering exams were first encountered on the PACS workstation. Whether these results represent clinicians' differential workstation utilization patterns or true effects of PACS/CR will be determined by further data analysis, including case mix adjustment, subgroup analysis, and multivariate modeling.
