What kind of new knowledge of nurses’ professional
turnover can we expect to get based on qualitative casestudy
approach?The purpose of this inquiry was not to seek
universal explanations of why young nurses leave nursing
profession. The results are not meant to be generalized to
a certain population [44] as case study research commonly
needs to be generalized theoretically [47, 53]. It is clear that
no one methodology by itself will be able to address nurse
turnover as a multifaceted phenomenon effectively. There
is still a need to statistically measure and model variables
connected with turnover [40]; also interventions to reduce
turnover intention need to be developed and tested [18]. The
advantage of large sample sized research is the breath and
the empirical generalizability of the evidence [47]. However,
as Flyvbjerg [44] remains, the disadvantage of this kind of
knowledge is one of depth; therefore, qualitative case studies
are needed as well.
