PHRD554 Public Health Practice Test 2026 – Comprehensive Exam Prep

Data governance in health systems is a comprehensive framework that defines policies, standards, and processes to manage data quality, privacy, security, and use across the organization. This means establishing who owns data, how data is collected and maintained, how accurate and reliable it is, and how it can be accessed and used in a safe and compliant way.

A strong governance program covers data quality management (ensuring accuracy, completeness, and timeliness), privacy protections (respecting patient confidentiality and legal rights), security controls (protecting data from unauthorized access and breaches), and the ways data can be used for care, operational decisions, and research. It also includes clear roles like data stewards, defined workflows, metadata and data lifecycle management, and rules for data sharing and interoperability.

This holistic view is why it’s the best answer: it goes beyond isolated concerns and creates an integrated approach that supports trustworthy data for patient care and system improvement while meeting regulatory and ethical obligations. When governance focuses only on privacy or only on security, or when it excludes access controls, important parts of data management are left unaddressed, which can lead to poor data quality, misuse, or compliance gaps.
