Obstinación terapéutica y su límite con la ética: ¿cuándo detenerse?

Abstract

Obstinacy or therapeutic cruelty is a medical practice based on the application of extraordinary and disproportionate methods of life support in terminally ill or irrecoverable patients. It is not without risks and can cause physical, psychological and social damage, which is why this practice is not ethically acceptable. It violates the four principles of bioethics: non-maleficence, beneficence, justice and autonomy. The reasons that lead to therapeutic obstinacy are: 1) lack of a definitive diagnosis; 2) false expectation of improvement of the patient; 3) disagreement (between doctors and family or between doctors themselves) with respect the patient’s situation; 4) difficulty in communicating with the patient and his/her family; 5) compliance with unrealistic or futile treatments; 6) cultural or spiritual barriers and 7) medical-legal aspects. Limitation of therapeutic effort (LTE) is a deliberate or thoughtful decision about the non-implementation or withdrawal of therapeutic measures that will not provide significant benefit to the patient. But, refusing a treatment, must not imply the artificial acceleration of the death process. Chile does not contemplate euthanasia or assisted suicide in its legislation. Criteria used to justify the limitation of the therapeutic effort are: 1) futility of the treatment (futility); 2) declared wishes of the patient; 3) quality of life and 4) economic cost. The Healthcare Ethics Committee of the Hospital de Urgencia Asistencia Pública has prepared a LET Clinical Guide, proposing a decision-making flow chart that takes in account the autonomy of the patient, the opinion of the medical team, patient and family. In case of disagreement, the Healthcare Ethics Committee’s may be requested to issue a pronouncement
