Improving the forensic genetic workflow for countries with small geographical areas: What are the options and how cost effective are they?

Forensic services worldwide often encounter considerable challenges relating to funding and infrastructure. Smaller jurisdictions or areas where forensic resources are scarce are faced with complicated choices in how they approach criminal casework, with a number of options available. Often these involve trade-offs between cost, time and data quality. Faced with such decisions it becomes important for the field to acknowledge the realities facing such jurisdictions, discuss the pros and cons of each approach, and identify a framework for making such decisions. This novel paper, reviews the available literature and identifies three main solutions for consideration: 1) the use of satellite laboratories for sample triage, 2) the use of a main regional laboratory for full forensic analysis and 3) the use of rapid DNA by police for reducing backlogs. Alongside these strategies, the impacts of cost and quality in regard to each of the stated options are considered. While the literature supports the assertion that some methods can reduce downstream costs via the reduction in turnaround times, there is limited data highlighting the business case used to support decision making when considering these options including the use of cost:benefit analyses or case studies, emphasizing the novelty of this paper. This is likely due to the commercialized nature of the forensic sector preventing the publication of a private laboratory’s business approach. The lack of emphasis on the ‘business case’ in forensic literature has the potential to mislead R&D scientists who may consequently fail to consider such factors when performing their own research.
