What is the role of data integrity in healthcare informatics?

• A. Limiting data access to one user.
• B. Maximizing data collection speed.
• C. Ensuring accuracy, consistency, and trustworthiness of data across systems.
• D. Reducing data quality to save costs.

Answer: (C)

In healthcare informatics, data integrity means keeping patient information accurate, consistent, and trustworthy as it moves through different systems. This is essential for patient safety, correct diagnoses, effective treatment, and reliable analytics across EHRs, labs, imaging, and billing. So the best answer emphasizes ensuring accuracy, consistency, and trustworthiness of data across systems. The other ideas miss the core purpose: restricting access focuses on security rather than data truth; speeding up collection affects performance, not data reliability; reducing quality would undermine safety and valid decision-making.
