Which statement about practice guidelines is true?

• A. They are statements including recommendations informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options
• B. They are not based on evidence and rely on opinion
• C. They are always legally binding
• D. They are optional and not required to follow

Answer: (A)

Practice guidelines are evidence-based recommendations created by systematically reviewing the available research and weighing the benefits and harms of different options to guide clinical decisions. This approach means the guidance isn’t just personal opinion; it uses explicit methods to evaluate what the evidence shows and how strongly it supports certain actions.

That makes the statement that they are informed by a systematic review of evidence and an assessment of benefits and harms the best description. They aim to standardize care and help clinicians choose options that are more likely to improve outcomes.

Guidelines aren’t automatically legally binding. They are generally advisory, and whether they become binding depends on policy, regulation, or institutional rules. Some settings require adherence to guidelines, but the guidelines themselves aren’t laws.
