Structural measures in healthcare quality assess the context in which healthcare is delivered, evaluating the capacity, systems, and processes of a healthcare provider to provide high-quality care12. They are used to assess the infrastructure of the facility or organization, including the physical equipment and facilities, technology, and human resources of a healthcare setting2.

An example of a structural measure is the number or proportion of board-certified physicians1. This measure gives consumers a sense of a health care provider’s capacity to provide high-quality care1. Therefore, option B, “proportion of board-certified physicians on staff,” is an example of a structural measure.

Options A, C, and D are not structural measures. Average medication administration time and rate of healthcare-acquired infections are process and outcome measures respectively, as they reflect what a provider does to maintain or improve health and the impact of the health care service or intervention on the health status of patients1. The percent of documents without errors could be considered a process measure, as it reflects the procedures and protocols followed in the healthcare setting.
