Pilot study
In the planning phase of the study, a data collection form was developed
using admission, hospitalization and hospital discharge variables
extracted from similar studies found in the
literature.7,26–28 Subsequently, the form was
piloted, with a convenience analysis of 92 medical records of patients
admitted in the second quarter of 2016, following the same eligibility
criteria and in the same study location. Data were analyzed by two
independent observers (L.M.C.S. and F.C.J.J.) under the supervision of a
third researcher (C.C.S.). Then, the form was expanded to include more
information regarding medication use at admission, hospitalization and
discharge.
