1. Background
Nursing services have been traditionally regarded as
free services included in medical services, so price competitions
in nursing have been deemed to be unethical [1].
Even today, although a large part of medical services is
performed by nurses, there are not many cases in which
nursing services are classified as independent services and
costs of the services are estimated or set. However, in modern
society, health care services have been continuously
growing with the development of scientific technologies,
and medical needs have become diverse and complex due
to demographic aging and socioeconomic changes, so the
diversification and professionalism of services are also required
in nursing as in other fields. Currently, nurses are
trained professionals who have acquired systematic theories
and skills and can fulfill health care needs.
