Laboratories and their criminal justice systems are confronted with challenges for implementing new technologies, practices, and policies even when there appears to be demonstrative benefits to operational performance. Impacting decisions are the often higher costs associated with, for example, new technologies, limited current budgets, and making hard decisions on what to sacrifice to take on the seemingly better approach. A prospective cost-benefit analysis (CBA) could help an agency better formulate its strategies and plans and more importantly delineate how a relatively small increase to take on, for example, a new technology can have large impact on the system (e.g., the agency, other agencies, victims and families, and taxpayers). To demonstrate the process and potential value a CBA was performed on the use of an alternate and more expensive swab with reported better DNA yield and being certified human DNA free (i.e., nylon 4N6FLOQSwabs®), versus the traditional less costly swab (i.e., cotton swab). Assumptions are described, potential underestimates and overestimates noted, different values applied (for low and modest to high), and potential benefits (monetary and qualitative) presented. The overall outcome is that the cost of using the more expensive technology pales compared with the potential tangible and intangible benefits. This approach could be a guide for laboratories (and associated criminal justice systems) worldwide to support increased funding, although the costs and benefits may vary locally and for different technologies, practices, and policies. With well-developed CBAs, goals of providing the best services to support the criminal justice system and society can be attained.
实验室及其刑事司法系统在实施新技术、实践和政策时面临挑战,即使这些新技术、实践和政策似乎对运营绩效有明显的益处。影响决策的因素通常是与新技术相关的较高成本、有限的当前预算,以及在牺牲什么以采用看似更好的方法方面做出艰难的决策。前瞻性成本效益分析(CBA)可以帮助机构更好地制定其战略和计划,更重要的是,阐明相对较小的增加(例如,采用新技术)如何对系统产生重大影响(例如,机构、其他机构、受害者和家庭以及纳税人)。为了展示这个过程和潜在的价值,我们对使用一种替代的、成本更高的拭子进行了 CBA,这种拭子据称具有更好的 DNA 产量,并且经过认证不含人类 DNA(即尼龙 4N6FLOQSwabs®),与传统的、成本较低的拭子(即棉签)进行了比较。描述了假设,注意到潜在的低估和高估,应用了不同的价值(低值、适度到高值),并提出了潜在的收益(货币和质量)。总体结果是,使用更昂贵技术的成本与潜在的有形和无形收益相比微不足道。这种方法可以成为全球实验室(和相关的刑事司法系统)的指南,以支持增加资金,尽管成本和收益可能因当地情况和不同的技术、实践和政策而有所不同。通过精心制定的 CBA,可以实现为支持刑事司法系统和社会提供最佳服务的目标。
