摘要	The Perceived Organizational Readiness for Assisting the System (PORAS) is a 19-item self-report measure developed by Helfrich and colleagues to assess organizational readiness to implement health information technology systems and other healthcare innovations. Grounded in Weiner's theory of organizational readiness for change, the PORAS measures four dimensions of readiness: Valence (perceived importance of the change to the organization), Motivation (organizational commitment and drive to implement), Resource Adequacy (availability of financial, human, and technical resources), and Change Efficacy (staff belief in organizational capability to successfully implement). While originally developed for health IT implementation, the PORAS framework and scale are applicable to broader healthcare innovations and evidence-based practice implementation.	The Implementation Climate Scale (ICS) is a brief organizational assessment tool that measures the extent to which an organization's work climate, policies, and systems are aligned with and supportive of evidence-based practice (EBP) implementation. Developed by Ehrhart, Aarons, and Farahnak in 2014, the ICS measures four dimensions of organizational implementation climate: Focus (degree to which EBP is a priority in organizational goals), Support (availability of resources and protected time for EBP), Reward (incentive structures and recognition for EBP use), and Expectations (leadership communication of expectations for EBP adoption and fidelity). The ICS provides a concise snapshot of whether organizational systems and policies actively facilitate or hinder EBP uptake, and has demonstrated strong predictive validity for implementation fidelity and sustainability.
