Which of the following is a type of outcome measure?

The correct answer is surveys, as they are a direct method of collecting information about the outcomes of interventions or treatments from the perspectives of patients or healthcare providers. Surveys can assess various aspects of health, such as patient satisfaction, quality of life, and symptom burden, making them integral to outcome measurement in evidence-informed practice. They provide critical data that help determine the effectiveness and impact of healthcare interventions.

In contrast, diagnostic tests are primarily used to identify diseases or conditions rather than measure outcomes. Operations refer to surgical or clinical procedures performed to treat conditions, and medications are substances administered to manage or treat health issues. While these components are essential in the healthcare process, they do not specifically serve as measures of outcomes like surveys do. Surveys uniquely capture patient-reported outcomes, making them invaluable in evaluating the effectiveness of healthcare practices.
