Final answer:
The correct group impacted by a fully functional EHR system is 'patients and healthcare organizations.' EHRs improve care coordination and efficiency, benefiting both sides while also presenting challenges concerning treatment costs, patient quality of life, and privacy.
Step-by-step explanation:
A fully functional Electronic Health Record (EHR) system can have a significant impact on various aspects of healthcare. When considering who is affected by EHRs, it is evident that both patients and healthcare organizations benefit from a robust and functional health record system. This leads us to conclude that the correct answer is 'patients and healthcare organizations'.
EHRs facilitate better coordination of care between different healthcare professionals and streamline processes, leading to improved patient outcomes. They also assist healthcare organizations in managing patient data more efficiently, which can reduce costs and improve the quality of care provided. However, it is crucial to balance the benefits of EHRs with considerations such as the cost of treatments, quality of life, and privacy risks.
