Artificial nutrition is a supportive medical therapy to attain pre-defined objectives, which should be adjusted to changing clinical situations. Optimal decision-making is based on the available scientific evidence blended with the science of probability and a spice of the art of uncertainty. Complex dilemmas in decision-making often occur given the paucity of solid scientific data to endorse precise indications and timing of prescription, whilst goals to be achieved may vary from clinical benefits to compassionate use. Hence, healthcare professionals must be aware and abide by the current norms of medical ethics, whereby eliciting and respecting patientsʹ preferences is paramount. Patient-focused care implies: to respect patientsʹ rights, to clearly inform and involve the patient in the decision-making process, to implement a therapeutic plan based on the best available care to suit patientsʹ needs and informed options.
