This guide provides an overview of the prosecutor's use of multidisciplinary collaboration to more effectively identify, prosecute and prevent elder abuse, neglect and exploitation. The guide suggests ways that multidisciplinary partnerships can assist prosecutors in effectively prosecuting individual cases and in improving systemic community responses to elder abuse. Topics include elder abuse and the challenge of prosecution; the role of the prosecutor; multidisciplinary collaboration, case-based multidisciplinary groups and systemic review multidisciplinary groups; participating in broader community-based coordination efforts, and a list of additional national organizations and resources. Examples of State and local collaboration models and online resources also are provided. The information presented in this guide is intended to complement two companion publications: Prosecuting Elder Abuse Cases: Basic Tools and Strategies and Prosecuting Elder Abuse Cases: Proposed Performance Measures.
