Change is necessary for growth where it is directed toward making something significant and different from what it was. This is because most of healthcare organizations operate as open systems. They are receptive to external and internal influences originating from rapidly changing health care delivery system. Aim of the study: it aims to manage change of the identified problems in the inpatient units using Lewin's theory. Tools: Needs Assessment Unstructured Interview to identify the major problems in the inpatient units and their solutions, and A questionnaire sheet was developed by the researcher to assess the problems facing nurses in their inpatient units before and after change. Results: showed that Lewin's theory solved problems encountered in the present study related to applying floating pool system to overcome shortage of nurses and establishing collaborative practice committees to overcome the poor communications. Yet, problems related to absent of job description, lack of incentives, poor maintenance of the inpatient units, and the narrow space of the nursing station were not eliminated.
