The 4 basic ethical principles according to Beauchamps and Childress (1994) are: autonomy, beneficence, non malefacence,
and justice.
The Principle of Autonomy is the power of the patient to decide on medical procedures.
The Principle of Non-maleficence is avoiding causation of harm.
The Principle of Beneficence is the providing benefits and balancing them against risks and costs.
The principle of justice is distribution of benefits, costs, and risks fairly
