Consent has three components: Disclosure, capacity and voluntariness.

• Disclosure: This involves provision of relevant information by the clinician and its understanding by the patient.
• Capacity: This refers to the patient’s ability to understand the relevant information and to understand the consequences of his/her decision that might reasonably be foreseen.
• Voluntariness: This signifies the patient’s right to take a decision freely, without force, coercion or any manipulation.
