Objective: To implement the preoperative Thirst Management Model, measuring its adoption, coverage, acceptability, feasibility and fidelity by nursing in a burn unit.
Method: Quasi-experimental, pre- and post-test intervention study. Sample of 59 patients at pre-implementation and 40 post-implementation and 36 nursing professionals participating in the implementation in a burn unit from August (2019) to March (2020). Statistical analysis used Mann-Whitney and Chi-square.
Results: Adoption of management ranged from 0.0% to 72.5% post-implementation. The capacity coverage was 87.5% of nurses and 87.9% of nursing technicians. There was acceptability and feasibility of thirst management by professionals. In the plan-do-study-act cycles, three pillars of the Model reached the goals, showing fidelity.
Conclusion: The implantation of the Preoperative Thirst Management Model had acceptability and feasibility by the nursing team, showing fidelity in achieving the proposed goals, in addition to the adoption of evidence in clinical practice after high coverage professional training.
