Which of the following is a main focus of Quality Assurance?

Quality Assurance (QA) primarily revolves around ensuring that data meets specific standards for accuracy, reliability, and validity. The focus on data accuracy is crucial because it determines the credibility of the data being used in decision-making processes, including patient care and treatment efficacy within oncology. If data is not accurate, it can lead to incorrect conclusions and potentially adverse outcomes for patients.

While data collection, comparison, and reporting are all important components of data management, they serve as processes that contribute to achieving data accuracy. Quality Assurance emphasizes implementing procedures and practices that monitor and improve the accuracy of the collected data, thereby ensuring that the information used for analysis, reporting, and other purposes is trustworthy. This focus on accuracy is critical in the field of oncology, where decisions about patient treatment and care are heavily reliant on high-quality data.
