INTRODUCTION In numerous countries legislation has been put in place allowing citizens to appointpersons authorized to make medical decisions on their behalf, should the principal lose such decision‑makingcapacity. OBJECTIVES The paper aimed to prepare a draft proposal of legal regulations introducing into Polishlegislation the institution of the health care agent. PATIENTS AND METHODSThe draft proposal has been grounded in 6 expertise workshops, in conjunctionwith several online debates. RESULTS The right to appoint a health care agent should apply to all persons of full legal capacity, andto minors over 16 years of age. Every non-legally incapacitated adult person would be eligible to be appointed a health care agent. Appointment of substitute agents should also be legally provided for. Theprerogatives of health care agents would come into effect upon the principals' loss of their decisionmaking capacity, or upon the principals' waiving their right to be provided with pertinent information ontheir health status. The health care agents would make decisions in all matters pertaining to medical treatment, while remaining under no obligation to perform any hands-on caring duties for their principals.The term of medical power-of-attorney should be discretionary, while its revocation or resignation should be possible at any time. In the event of health care agents' inactivity, or in the event that their actionsshould appear contrary to the principals' best interests, an attending physician should notify a pertinent court of law whose prerogatives would facilitate revocation of a medical power-of-attorney. CONCLUSIONSStatutory appointment of a health care agent allows every citizen to appoint in this capacitya person who, to the best of his or her knowledge, would best represent his or her interests in the eventthat the principal should ultimately lose the capacity to make medical decisions on his or her own behalf.
