NICE develops guidelines through a rigorous process that includes extensive literature reviews, consultations with experts, and input from stakeholders. The process involves several stages: 1. Scoping: Identifying the key areas that need addressing. 2. Drafting: Developing initial recommendations based on evidence. 3. Consultation: Seeking feedback from healthcare professionals, patients, and other stakeholders. 4. Finalizing: Incorporating feedback and publishing the final guidelines.
