Medical Informed Consent Chile

Medical Informed Consent Chile (Consentimiento Informado Médico) is a legal document governed primarily by Ley 20.584 of 2012 (Ley sobre derechos y deberes que tienen las personas en relación con acciones vinculadas a su atención en salud), specifically Articles 10 through 14, which establishes the right of every patient to receive complete, timely, and comprehensible information about their health condition and the proposed medical intervention, and to freely and voluntarily accept or refuse treatment after receiving that information. This framework applies to all healthcare providers in Chile — public hospitals and centros de salud under the Red Asistencial del SNSS (Sistema Nacional de Servicios de Salud) managed through FONASA, and private establishments (clínicas, centros médicos) operating within the ISAPRE system regulated by the Superintendencia de Salud.

Ley 20.584 Article 10 establishes the foundational right to information: every person has the right to be informed — in understandable terms (en forma oportuna, comprensible y veraz) — about the purpose, nature, risks, and expected benefits of the proposed medical or surgical treatment, as well as the alternatives available and the consequences of not receiving treatment. The information must be provided by the treating physician (médico tratante) or the responsible healthcare professional, not by administrative staff. MINSAL Circular N.° 22 of 2014 specifies the minimum content required in informed consent documentation across health establishments.

Article 14 of Ley 20.584 specifically addresses the written consent requirement: for invasive diagnostic procedures, surgical interventions, medical treatments with significant risk, and any procedure requiring general or regional anesthesia, the patient's consent must be documented in writing and filed in the patient's clinical record (ficha clínica). The document must state that the patient received the required information, understood it, and voluntarily accepts the proposed treatment. The Reglamento de la Ficha Clínica (Decreto Supremo N.° 41 of 2012 of MINSAL) requires retention of signed consent forms as part of the ficha clínica for a minimum of 15 years.

Article 11 of Ley 20.584 establishes the patient's right to know the identity of the treating professional and to change healthcare providers. Article 12 provides the right to access the ficha clínica and all medical records. Article 13 codifies the right to refuse treatment — a competent adult patient can decline any medical intervention, including life-saving procedures, as long as the refusal is made with full information and is not under duress. The treating physician must document the patient's informed refusal (rechazo informado) in the ficha clínica, and may not proceed with the refused treatment.

The Superintendencia de Salud — the Chilean regulator overseeing both FONASA beneficiaries accessing private providers under the Modalidad de Libre Elección and ISAPRE beneficiaries — has issued guidance (Circulares de Atención al Usuario) establishing that failure to obtain written informed consent before significant medical procedures constitutes a violation of patients' rights under Ley 20.584, which can result in administrative sanctions, civil liability, and complaints before the Defensoría del Paciente or the regional Secretarías Regionales Ministeriales de Salud (SEREMI de Salud).

Beyond Ley 20.584, the informed consent framework in Chile is reinforced by: the Constitución Política de la República Article 19 N.° 1 (right to physical and psychological integrity — integridad física y psíquica); the Código de Ética Médico (Colegio Médico de Chile) Articles 23–27; the Ley 18.600 (Normas sobre Deficientes Mentales) for patients with intellectual disabilities; and the Ley 20.422 (Establece normas sobre igualdad de oportunidades e inclusión social de personas con discapacidad) requiring accessible communication formats for patients with disabilities.

A Medical Informed Consent form under Ley 20.584 is required before any significant medical procedure in Chile, covering a broad range of clinical contexts across both public and private healthcare systems.

Surgical procedures: Any operation performed under general anesthesia, spinal anesthesia, or regional nerve blocks — from appendectomies and caesarean sections at hospitales públicos (Hospital del Salvador, Hospital Barros Luco, Hospital Sótero del Río, Hospital San Juan de Dios) to elective cosmetic surgery (cirugía estética) at private clínicas such as Clínica Las Condes or Clínica Alemana — requires a written informed consent form. The Sociedad de Cirujanos de Chile endorses pre-operative consent protocols aligned with Ley 20.584.

Invasive diagnostic procedures: Colonoscopies, cardiac catheterization, bronchoscopy, liver biopsies, lumbar punctures, and other invasive diagnostic tests at centros de diagnóstico (CDT) or hospital units require informed consent confirming the patient understands the procedure, its risks, and alternatives. Interventional radiology procedures at radiology centers regulated by the Superintendencia de Salud follow the same requirement.

Chemotherapy and radiation therapy: Cancer treatment at the Instituto Nacional del Cáncer, the Red Oncológica of FONASA, or private oncology centers (Fundación Arturo López Pérez — FALP) requires detailed informed consent covering drug toxicity profiles, radiation exposure, and palliative care alternatives as required by MINSAL's Normas Técnicas Oncológicas.

Psychological and psychiatric treatment: Involuntary hospitalization and certain intensive psychiatric treatments require consent under Ley 20.584 Article 29 (protección de personas con enfermedad mental), which establishes heightened procedural protections for psychiatric patients. The Unidades de Psiquiatría Forense and psychiatric hospitals must comply with these informed consent requirements.

Clinical trials and experimental treatments: Research involving human subjects at Chilean universities (Universidad de Chile, Pontificia Universidad Católica de Chile, Universidad de Concepción) and research hospitals requires ethics committee approval (Comité Ético Científico) under Ley 20.120 (Sobre la investigación científica en el ser humano) and informed consent documents meeting more stringent disclosure requirements than routine clinical care.

A valid Medical Informed Consent document in Chile under Ley 20.584 Articles 10–14 must include the following essential elements to satisfy the legal requirements established by MINSAL, the Superintendencia de Salud, and the Colegio Médico de Chile:

Patient Identification (Individualización del Paciente): Full legal name, RUT, date of birth, FONASA or ISAPRE affiliation number, and contact information. For FONASA beneficiaries, include the FONASA tramo (A, B, C, or D) as this affects co-payment obligations. For ISAPRE beneficiaries, include the ISAPRE name and policy number. The identification section confirms the patient's identity and establishes the legal subject of the consent.

Healthcare Provider Identification (Identificación del Prestador): Full name, RUT, specialty, and Registro Nacional de Prestadores Individuales de Salud number of the treating physician or surgeon. The Superintendencia de Salud maintains the Registro Nacional de Prestadores Individuales, and the physician's registration number confirms their legal authority to perform the procedure. Include the name, RUT, and MINSAL inscription number of the healthcare establishment.

Diagnosis and Clinical Condition (Diagnóstico y Estado Clínico): A clear, plain-language description of the patient's diagnosis or clinical condition that makes the proposed treatment necessary or advisable. Per Ley 20.584 Article 10, this explanation must be in terms understandable to the patient (no exclusive use of technical medical jargon without explanation). The ICD-10 or ICD-11 diagnosis code may be included for clinical record purposes.

Description of Proposed Treatment (Descripción del Tratamiento Propuesto): A specific and complete description of the medical or surgical procedure to be performed — the name of the procedure, how it will be performed (technique), the expected duration, the type of anesthesia (if applicable), and the facility where it will be carried out. Vague descriptions such as 'surgical procedure as needed' do not satisfy the Ley 20.584 Article 14 requirements.

Risks and Benefits (Riesgos y Beneficios): Disclosure of the significant risks and expected benefits of the proposed treatment, presented in a manner that allows the patient to make an informed decision. Chilean courts applying Ley 20.584 have held that the disclosure must cover material risks — those that a reasonable patient would consider important in deciding whether to undergo the procedure — not merely rare or statistically insignificant risks. For procedures regulated by MINSAL's Garantías Explícitas en Salud (GES/AUGE) program, the disclosure must align with the corresponding clinical protocol.

Alternatives to Proposed Treatment (Alternativas al Tratamiento): A description of medically reasonable alternatives to the proposed procedure, including the alternative of not receiving treatment and the expected consequences of each option. Article 10 of Ley 20.584 explicitly requires disclosure of treatment alternatives.

Consent Declaration and Signature (Declaración de Consentimiento y Firma): The patient's (or legal representative's) express written statement that they have received, understood, and accepted the information provided; that their decision is free and voluntary; and that they authorize the healthcare provider to proceed with the described treatment. Signature, date, and RUT of the consenting person are required. A witness signature is best practice for procedures with significant risk.

Right of Withdrawal (Derecho a Retractarse): A clause reminding the patient of their right to withdraw consent at any time before the procedure begins, consistent with Ley 20.584 Article 14 inciso final, which provides that consent can be revoked without penalty until the commencement of the intervention.
