Background. The continuous increase in healthcare spending and problems experienced in payment/ insurance systems have brought the issue of hospital extravagance to the agenda. To achieve efficiency in the healthcare sector and prevent wasteful behavior, it is important to use all resources in a costeffective manner. This study aimed to determine the views of healthcare workers on wasteful behavior in hospitals. Material and methods. This study employed a descriptive qualitative design. The data were collected through in-person in-depth interviews with 60 participants working at private, university and state hospitals. A semi-structured interview form was used in the study. The Consolidated Criteria for Reporting Qualitative Studies (COREQ) were applied to organize and report the study. Results. The data obtained in the study were examined under two themes named "Wasteful Behavior" and "Precautions", as well as categories under these two themes. Conclusions. The participants stated that there are many aspects of extravagance practiced at hospitals, but they saw the sustainable use of resources with a set of precautions to be taken possible. Presenting the views and recommendations of healthcare professionals will provide an important source of data for administrators in terms of sustainability efforts.
