The concept of care bundle; It was developed by the American Institute for Healthcare Improvement (IHI) in 2001 to provide the best care safely in order to achieve desired results in patient care, increase compliance with standard procedures, improve patient safety and quality of care. Ensuring that nurses perform gastrostomy care correctly and according to the guidelines published in international standards will minimize the development of problems that may arise in gastrostomy care. The aim of this study was to development and implementation the gastrostomy care bundle for gastrostomy care.

Method: The research was planned as a mixed type research design in order to development and implementation the gastrostomy care bundle for gastrostomy care. The study was planned to be carried out in Hacettepe University Adult Hospital Brain and neurosurgery intensive care unit between September 2021 and September 2022. In the quantitative phase of the research; The development of the gastrostomy care bundle will be carried out using the care bundle development approach in line with the recommendations of the Institute for Healthcare Improvement (IHI) and expert opinions will be taken. Nurses working in the brain and neurosurgery intensive care unit will be trained on the gastrostomy care bundle and will be expected to practice care bundle. Before the training, nurses will be asked to fill in the "Nurse Introductory Information Form", "Evidence-Based Attitude Scale towards Nursing" and "Gastrostomy Care Questionnaire (pre-test)". The nurse population of the research will consist of 14 nurses working in the brain and neurosurgery intensive care unit. At this stage, the sample selection will not be made, and it will be tried to reach all of the working nurses. The "Gastrostomy Care bundle" form will be used by the nurses in the gastrostomy care in the brain and Neurosurgery intensive care unit between September 2021 and September 2022 , which is determined for the patient sample. Nurses' compliance with the care bundle will be evaluated by the researcher with the "Gastrostomy Care Bundle Compliance Evaluation Control Form" by making daily visits to the intensive care unit. At the end of the period determined for the use of the care bundle in the intensive care unit, the nurses will be asked to fill in the "Evidence-Based Attitude Scale towards Nursing" and "Gastrostomy Care Questionnaire (post-test)". In the qualitative phase of the research, nurses working in the brain and neurosurgery intensive care unit will be interviewed about their experiences with the use of gastrostomy care bundle. At the end of the study, nurses' compliance with the use of care bundle, the effect of gastrostomy care bundle use/gastrostomy education on nurses' knowledge levels and attitudes towards evidence-based nursing, and nurses' views on gastrostomy care bundle will be evaluated.
