Estimating the nursing staff required in a new hospital.

Opening a new hospital poses a complex and consequential set of challenges. One of these challenges is to estimate the nursing staff. The aim of this article is to report the entire process adopted to estimate the required nursing staff for a new Hospital in Brazil. The nursing staff was projected according to the Brazilian Federal Nursing Council (Cofen). We applied an equation to estimate nursing staff and compared the results with two other existing hospitals. A significant difference (p<0.05) was observed when comparing the Nurse-License Practice Nurse ratio recommended by Cofen between the new Hospital and other hospitals. This statistical difference is mostly due to reduced nurse staff in intensive care units. Almost one year after the hospital opened its doors, it is necessary to review nursing staff hours with the real information to reinforce the expenditure on these personnel and to evaluate the decisions made so far.
