Medico-legal Update, January-March 2020, Vol. 20, No. 1 2327 The Patient Safety Model within Decubitus Ulcer Patients in Hospital: Based on the Organizational Citizenship Behavior and Knowledge Management Tri Johan Agus Yuswanto 1 , Naya Ernawati 1 1 Lecturer, Health Polytechnic of Malang, Indonesia Abstract Decubitus ulcer event is an indicator of patient safety in nursing care at the clinic, so a method is needed to reduce the incidence of decubitus ulcer in the patient in hospital. The research aims to create a model for increasing patient safety based on Organizational Citizenship Behavior (OCB) and knowledge management on unexpected events (decubitus ulcer) in achieving the target of patient safety program in Hospital, using cross-sectional design. The subjects were 100 nurses who work in the inpatient room of Surabaya Haji Hospital, selected by purposive sampling. Data collection was done by questionnaire, then analyzed using Partial Least Square (PLS). The model of increasing patient safety based on OCB and knowledge management has proven effective in reducing the incidence of decubitus ulcer in the patient ward. This model is recommended to implement in the hospital to enhance the quality of nursing care.

Patient safety is a top priority in providing services to patients related to the issue of quality and image of the hospital. Safety is a fundamental principle of patient care and a critical component of quality management (2) . Patient safety in hospital includes managing risks, identifying and managing risks to patients, analyzing incidents, learning abilities and following up incidents, and implementing solutions to reduce risk. Nurses are the key to development quality through patient safety (3) . The incidence of decubitus ulcer patients is an indicator of patient safety in clinical nursing care. If the patient safety indicator has not reached the specifed standard, it will affect the quality of services. As a result of the frequent occurrence of decubitus ulcer patients are at risk of increasing unexpected events or at risk of occurrence of adverse events. Basically, the performance of individuals or groups is what ultimately affects the progress of the organization as a whole. Other factors that affect individual performance which ultimately lead to organizational performance are OCB. OCB can be defned as extra behavior related to work outside of routine tasks determined by job descriptions or measured in formal evaluations (4) . OCB is implemented for a long time and by many people it will result in organizational effectiveness (5) . The components of OCB are: altruism, conscientiousness, sportsmanship, civic virtue, courtesy. Knowledge management is used as an effort to maintain, analyze, organize, improve, and share understanding and experience. Such understanding and experience is built on knowledge, both manifested in individuals or inherent in the processes and real applications of an organization. Knowledge management is used by organizations as a new innovation to channel raw data into information and knowledge. Unexpected events occur because nurses commit negligence or errors in handling decubitus ulcer due to various factors DOI Number: 10.37506/v20/i1/2020/mlu/194655
