Objective: to elaborate an interpretative model for the governance of professional nursing
practice in a hospital setting. Method: a mixed methods study with concurrent triangulation strategy, using data from a
cross-sectional study with 106 nurses and a Grounded Theory study with 63
participants. The quantitative data were collected through the Brazilian Nursing
Work Index - Revised and underwent descriptive statistical analysis. Qualitative
data were obtained from interviews and analyzed through initial, selective and
focused coding. Results: based on the results obtained with the Brazilian Nursing Work Index - Revised, it
is possible to state that nurses perceived that they had autonomy, control over
the environment, good relationships with physicians and organizational support for
nursing governance. The governance of the professional nursing practice is based
on the management of nursing care and services carried out by the nurses. To
perform these tasks, nurses aim to get around the constraints of the
organizational support and develop management knowledge and skills. Conclusion: it is important to reorganize the structures and processes of nursing governance,
especially the support provided by the organization for the management practices
of nurses.
