Description

Background: Portugal's ability to respond to terrorist threats remains challenging and complex. According to Vegar [1], the intricate nature of the Portuguese legal system, which regulates each institution's working competencies, interactions, and chain of command, is too strict. These regulations and legal attributions present several difficulties in fulfilling the mission of responding to and combating terrorism, especially when the threat is chemical or biological [1-3]. Objective: This work aims to design/elaborate/prepare a questionnaire to be filled in by all the responder entities (e.g., Civil Protection Authorities, GNR, Instituto Dr. Ricardo Jorge, Armed Forces Hospital, among others) in case of an event. Methods:This questionnaire will contain twenty questions designed to gather information from institutions identified in the CBRN nº3 Operational Directives [2]. Fisher's Exact Test will be applied to the statistical analysis for the Closed questions to identify associations between variables. The weighted average will be calculated for the prioritization questions, and Kendall's Concordance Coefficient (W) will be used to assess agreement between respondents. For the free response questions, a content analysis will be carried out to identify recurring themes and patterns, followed by a Cluster Analysis to identify specific profiles or patterns. Results: The main goal is to evaluate the readiness of each officially deployed institution when faced with biological and chemical threats. By accurately identifying the institutions involved, we can clarify the response hierarchy, map their interconnections, and detail the procedural protocols for their intervention. Additionally, it is crucial to specify the types of threats each laboratory or institution is prepared to manage. Creating multidisciplinary assessment tools to identify the procedures adopted is fundamental to complementing the information previously obtained in the literature review. Conclusions: The results will allow the development of a checklist of multidisciplinary guidelines, raise awareness among authorities/entities, and promote investment in improving protocols to increase preparedness and mitigate the consequences.
