Final answer:
The quality improvement coordinator is required to implement patient care improvements based on both evidence-based performance guidelines, such as those from the NCCN, and results from studies measuring quality and outcomes, making the answer 'Both (A) and (B)'.
Step-by-step explanation:
The quality improvement coordinator in a healthcare setting is required to implement patient care improvements based on a combination of evidence-based performance guidelines and results from completed studies that measure both the quality of patient care and outcomes. Specifically, the NCCN (National Comprehensive Cancer Network) provides evidence-based guidelines that can serve as a basis for improving patient care. Additionally, results from completed studies offer valuable insights into the effectiveness of current practices and suggest where improvements can be made.
Given these considerations, the correct answer to the question is Both (A) and (B). This integrated approach ensures that patient care improvements are grounded in the best available evidence and tailored to the specific outcomes observed within the healthcare setting.
