The "Hospital" module is intended for hospitals. Admission to the hospital (to ward) is carried out on the basis of an disposal given by a doctor at the emergency room (and in the case of NHF stays of a referral issued there). A stay in a hospital is treated as a series of events, each of which is understood as the uninterrupted period of a patient's stay in one ward in one day. According to this definition, each ward change and each extension of stay for the next day result in the occurrence of a new event in the course of events constituting a hospital stay. As a part of the stay, patients may be transferred within the ward and between wards. Transfer to another ward is based on the transfer disposal issued by the doctor in the ward. During the stay, operations, consultations, diagnostic examinations and vaccinations can be carried out in parallel. The stay ends with a discharge (due to the end of the treatment process or death of the patient) based on the disposal issued by the doctor in the ward. An example of a hospital stay schedule:
