Objective: to discover varieties of missed nursing care and to understand the possible impact for both nurses as well as patients. Method: A systematic review was utilized. Data were collected from six databases. These databases were Science Direct, PROQUEST, Scopus, SAGE, PubMed, and Wiley, from a period of 2015 to 2019, were retrieved using the following keywords: “nursing care”, “missed nursing care” “impact missed nursing care” “nursing care left undone”. Results: 23 collected articles show three categories, to name the categories: missed nursing cares, influencing factors, and the impact of nursing cares. The missed nursing cares include nurse care planning, patients’ basic needs fulfilment, and documentation. Nurses’ perception on patient safety, self-accountability, human resources eligibility and adequacy, communication, workspace, manager influence, and patient’s characteristic become the factors of missed nursing care. The possible effect to this issue can lead to the patient’s satisfaction decline, nurse’s work satisfaction decline, as well as cost swell due to the extended length of stay and readmission after every 30 days passed. Conclusions: Planning, intervention, and documentation are the main duties of nurses. However, these duties are notoriously often missed by nurses. Reasons behind this issue are the characteristic of nurse, human resource problem, communication, workspace, manager influence. Of course, if left unchecked it will have an impact on patient satisfaction, nurse job satisfaction to high cost because LOS is long. The role of nursing managers is very large in improving nursing care that is missed.
