Healthcare informatics is of recent origin and is still evolving. It aims to link information technology, communications and healthcare to improve the quality of healthcare. In healthcare informatics, the healthcare information that is acquired is stored, retrieved and used as and when necessary fostering better co-ordination among healthcare providers. Health informatics is not just health IT and goes beyond that. It is the science of how and why and applies to the concepts, theories and practices in real-life situations for better health outcomes. In health informatics, the data is collected, stored and analyzed in digital format.
Hospital Management system aims to achieve efficient management of the hospital’s day-to-day functions enhanced patient care and better financial control.
At its basic form, EHRs can be thought of as a digitized version of patient records. EHRs are real-time patient-centric records. The patient information is available, whenever and wherever needed. EHRs contain information about a patient’s medical history, medications, immunizations, allergic reactions, lab reports and images etc. But the key feature of EHR is that it can be accessed and managed by authorized service providers, medical professionals and staff across hospitals and healthcare organizations. Electronic Medical Record often interchangeably used with Electronic Health Record is slightly different from EHR. EMR contains the clinical data at a particular hospital or health unit. In that sense, EHR is more comprehensive in nature as it contains the data collected at various sources.
Electronic Health records record the patients’ medical history, demographics, physical examination, results and findings of the laboratory and other clinical findings including medication. Hospital Information systems automate the clinical, medical, administrative and inventory functions. Hospital information system results in improved operational efficiency, cost benefits and better health care.
Hospital Information system is a comprehensive system covering every aspect of hospital management and operations. The HIS platform has the functionality to handle all kinds of patients and in emergencies. HIS takes care of all operations of a hospital from Help Desk/Reception to Patient Registration, Scheduling of appointments, Admission, Billing, Laboratory, Radiology reporting and review, Discharge summary etc. Other subsidiary systems such as Laboratory information system, Radiology Information System, Cardiology Information System, Material Management System and Clinical Data Repository are some of the modules that can be integrated with the Hospital Information System.
A typical Hospital Information System envisages the streamlining of the hospital processes and improves overall efficiency, reducing patient waiting time. Repetitive administrative tasks and duplication of information is avoided. Hospital Information System can be considered as an ERP system that encompasses the clinical, financial and supporting applications required for a hospital.
