The purpose of this study was to establish data points (benchmarks) to incorporate into a pro-forma cost analysis model, comparing film-based and filmless modes of operation. Prospective data were collected over a 6-year period at the Baltimore VA Medical Center (BVAMC) immediately before and after implementation of a hospital-wide PACS. These data were in turn compared with local and national VA centers during comparable time periods, to establish reference data between manual film-based (without PACS) and filmless operations (using PACS). Benchmarks utilized for the study fell into 2 broad categories: operational costs and revenues generated. Factors contributing to operational costs include space requirements, equipment, supplies, personnel, and maintenance. Factors contributing to revenues generated included examination volume, modality mix, and reimbursement rates. Collectively, these data points were incorporated into a pro-forma model that allows prospective PACS customers to compare total cost of ownership for film-based and filmless operations dependent on the unique variables of the respective institution.
本研究的目的是建立数据点（基准），以纳入预估成本分析模型，比较基于胶片和无胶片的操作模式。在巴尔的摩退伍军人医疗中心（BVAMC）实施全院PACS之前和之后的6年期间收集了前瞻性数据。这些数据又与同期的当地和国家退伍军人医疗中心进行比较，以建立基于手动胶片（无PACS）和无胶片操作（使用PACS）之间的参考数据。本研究使用的基准分为两大类：运营成本和产生的收入。导致运营成本的因素包括空间需求、设备、耗材、人员和维护。导致产生收入的因素包括检查量、模式组合和报销率。总体而言，这些数据点被纳入一个预估模型，该模型允许潜在的PACS客户根据各自机构的独特变量比较基于胶片和无胶片操作的总拥有成本。
