The term “consent” simply means assent or giving permission. This term can be broadly elaborated as an approval made by person for some activity. Consent is generally taken for a purpose so that the individual may allow to carry on the purpose or with the consent or permission of the respected individual, the purpose could be fulfilled. There is vast difference between a consent and informed consent. Informed consent is an important principle of health care and helps in averting medical errors. When people talk about informed consent, then it means that people are talking about a whole process in which the person whose consent is important is informed about the benefits or the risk associated with the purpose for which consent is required (Brown, 2011). Informed consent can be defined as a process in which information is given to the client related with the treatment such as benefits, risk as well as alternate treatment authorizing client or user to involve their self in and make informed and self-directed decisions ensue for the treatment. An informed consent intersects and embraces following concepts: legal, ethical and administrative aspects. By ethically, it supports and defends the decision made by the client autonomously. Legally, it turns out as safeguard against assault. Finally, administrative purpose makes sure that legal and ethical factors of informed consent are instigated and documented appropriately.
