Time management and knowledge management are two important and influential components in the quality of care and in improving the performance of nurses, especially in the special care department; therefore, this study was conducted to determine the relationship between knowledge management and time management in supervisors working in special care units. The present study was a cross-sectional study that was conducted to determine the relationship between knowledge management and time management in 384 supervisors working in intensive care units. Nurses have the position of supervisors and were selected by informed consent and by census method. The participants completed demographic, time management, and knowledge management questionnaires. The findings of this study showed that the majority of people were female (189 people (93.1%)) and married (196 people (96.6%)). Time management in supervisors working in the special care department studied in most cases (177 people (87.20%)) is at the average level, and in terms of knowledge management scores, knowledge management in supervisors working in the special care department studied in most cases (186 people (91.62%)) were at a weak level. There was a significant relationship between knowledge management and time management (P < 0.05). According to the findings of the present research, the score of time management was at an average level and the score of knowledge management was at a weak level, therefore, including educational content related to these two subjects in the educational program of undergraduate students and designing in-service training courses, especially for nurses and supervisors are effective and can help improve the situation.
