Informed Consent

Definition

Informed consent is the formal mechanism by which a competent individual voluntarily authorizes an intervention, procedure, treatment, research participation, or use of personal data, after receiving disclosure of all material information necessary to make a meaningful decision. The doctrine has three constitutive elements: (1) capacity — the cognitive ability to understand, appreciate, reason about, and communicate a choice; (2) voluntariness — absence of coercion, manipulation, or undue influence; (3) disclosure — accurate, intelligible information about the nature of what is proposed, its risks, its expected benefits, reasonable alternatives (including non-action), and the right to refuse or withdraw without penalty.

Manažerské shrnutí

Informovaný souhlas je formální mechanismus, kterým způsobilá osoba dobrovolně autorizuje zákrok, výzkumnou participaci nebo zpracování osobních údajů poté, co obdržela všechny podstatné informace. Tři neoddělitelné prvky: způsobilost (cognitive capacity), dobrovolnost (absence donucení a nepatřičného vlivu), a řádné poučení (adequate disclosure). V Prismatic Platform se princip aplikuje napříč klinickým výzkumem, behaviorálními studiemi, AI/ML výzkumem na lidských datech, OSINT operacemi (tam, kde je relevantní souhlas subjektu), a v DD kontextu při získávání informací od zaměstnanců cílové firmy a third-party respondentů. České právo ho zachycuje skrze § 31 zákona o zdravotních službách, GDPR (čl. 6 a 7), a v občanskoprávním rámci přes § 93 OZ a § 96 OZ.

The modern doctrine emerged from the Nuremberg Code (1947) and was elaborated through landmark cases — Salgo v. Stanford (1957), Canterbury v. Spence (1972) — that established the reasonable patient standard in U.S. medical practice (what a reasonable patient in the position of the actual patient would want to know). U.K. doctrine moved closer to this standard in Montgomery v. Lanarkshire Health Board (2015). EU clinical research is governed by EU 536/2014; data-protection consent is governed by GDPR Article 7 with the demanding requirement that consent be "freely given, specific, informed, and unambiguous." Czech zákon 372/2011 Sb. § 31 codifies medical informed consent; § 93 and § 96 OZ govern personality-rights consent. Common pitfalls include: technical jargon undermining comprehension, blanket consents covering unforeseen uses, time-pressured consent, and structural coercion (employees consenting to employer-sponsored research).

Practical Application

A defensible consent form is short enough to be read, written at the participant's reading level (typically 8th-grade for general populations), and supplemented by a verbal conversation in which the participant can ask questions. Key components: purpose, procedures, time commitment, risks (physical, psychological, social, economic), benefits (with honest acknowledgment when none accrue to the participant), alternatives, confidentiality protections, data retention and use, contact information, and a clear statement of the right to withdraw. For research involving transformative interventions, vulnerable populations, or complex data use (genomic, AI training corpora), staged or dynamic consent models are increasingly recommended. In due-diligence operations, informed consent governs participant interviews, employee assessments, and any processing of personal data that does not fall under another GDPR lawful basis.
