The purpose of this toolkit is to help individuals understand the legal framework that directs public health systems (PHS) agents to work in collaboration with each other. It does this by mapping which body of law dictates a relationship, as well as by comparing variations between different jurisdictions in preparedness and response capacity for emergency incidents. The Legal and Ethical Indicators for Adaptive Response toolkit consists of two tools, the Legal Network Analyzer (LENA) and the Emergency Law Database (ELDB). LENA exists as both a standalone program and as a web-based applet. In LENA, public health system relationships can be identified within a state, as well as compared between states, or between a state and the federal government. It does this by allowing policymakers to visualize legal relationships between public health system (PHS) agents as mandated by federal or state statutes and regulations. LENA creates said visual representations by referring to the Emergency Law Database, a comprehensive catalogue of over 5,900 laws and regulations regarding emergency preparedness and response activities in several states (see below). They can be searched by using keywords for a given action, and filtering them by emergency type, and/or by organization. The laws are coded to denote the actions, purposes, goals, and conditions each agent is directed to undertake by their respective legislature. It is important to note that not all of the laws and regulations are included in these jurisdictions. This toolkit is designed for public health officials and practitioners. Network maps can be created for the following jurisdictions (due to limitations in the scope of the ELDB): Alaska, California, Florida, Kansas, Maryland, New York North Dakota, Ohio, Pennsylvania, Rhode Island, Texas, Wisconsin, and the federal government.
