A healthcare system in Poland gives paramedics considerable professional independence and a wide scope of authority to perform healthcare services independently. There is, however, no effective supervision of their substantive performance by professional self‑government, voivodeship consultants or other entities. The only area of paramedics’ medical activity which undergoes substantive supervision is using means of physical coercion by them. Lack of substantive supervision over medical rescue services should be recognized as adverse both for patients prior to their admission to a hospital and paramedics due to lack of factual support in their work and lack of professional training based on the analysis of adverse events. It is essential to take legislative action providing a basis for introduction of methods of substantive supervision into the paramedics’ work. The study analyzes law regulations in respect of possibilities of provision of substantive supervision over paramedics’ work, and a comparison of supervision over performance of other medical jobs, in particular physicians, nurses and physical therapists.
