In the research, parallel data type was used in the convergent parallel mixed design (convergent parallel) in order to obtain meticulous, valid and reliable data through survey questions and individual interviews. In the quantitative dimension of the research, nurses working in internal medicine, neurology, cardiology and surgical intensive care clinics of a public hospital were examined.

While determining their level of knowledge regarding the prevention of pressure ulcers, it is also aimed to determine their experiences regarding practices to prevent pressure ulcers in a qualitative dimension.

This study is a mixed method research conducted to determine the knowledge levels and experiences of nurses working in adult intensive care units regarding the prevention of pressure sores. In accordance with the purpose of the study, parallel data type in convergent parallel mixed design will be used as the research design. The quantitative phase will be conducted as a descriptive survey, and the qualitative phase will be conducted as a descriptive case study design. In this mixed design, equal priority, parallel timing and combining results during interpretation are planned.

Pressure Ulcer Knowledge Level Assessment Tool 2.0-Updated Version (PUKAT 2.0): The Turkish adaptation of the PUKAT 2.0 measurement tool was made by Dallı et al. (2021). PUKAT 2.0 is a measurement/test tool scored as multiple choice true-false. It consists of a total of 25 questions. It is scored according to the number of correct answers given by the individual. The Cronbach Alpha value of the internal consistency reliability of the measurement tool was found to be 0.72. All results will be coded as binary variables: correct (1) and incorrect (0). If the answer is not known, more than one answer or no answer is selected, the result will be coded as incorrect. The total score for each participant will be calculated as the sum of the correct answers. The minimum score to be obtained from the scale is 0 and the maximum score is 25. As the scores increase, the level of knowledge increases.

The qualitative data obtained from the research will be evaluated with inductive content analysis. In order to increase the validity of the data, two researchers will examine the transcripts separately and comprehensive readings will be made. Codes will be created and compared by interpreting them in terms of differences and similarities, categories and sub-themes will be obtained. Main themes and sub-themes will be determined and research objectives will be tried to be given within the framework of the pattern between the interviews.
