A Health Information System, (HIS), is defined as a "set of components and procedures organized with the aim of generating information that will improve" financial management and clinic for hospitals and doctors' offices. (Lippeveld, Sauerborn and Bodart 2000). HIS is central to the development of hospital and medical practices for the purposes of strategic planning, problem solving, decision support and executive information systems with which health service managers and clinicians are deeply involved. There are two main divisions that contribute to the functionality of the HIS, the financial information systems and the clinical decision support system. The combination of these systems has enabled the advancement of the healthcare community in data compilation and its financial well-being. Due to the current financial situation of the United States, as well as with the passage of ObamaCare, the shrinking budgets of healthcare facilities have forced them to adopt rigorous accountability measures. These steps were undertaken by the Financial Information Systems (FIS), which provides information on both the acquisition and allocation of funds in hospital and medical settings. The FIS allows comparisons between success and failure in providing healthcare services in a cost-effective manner. FIS will calculate the income statement and balance sheet for the healthcare facility, thus allowing appropriate algorithms for the acquisition and introduction of material within the facility. For example, in a hospital emergency room, FIS calculates how many patients arrive at the hospital with the diagnosis of pneumothorax (air trapped in the lung). Taking this into account... half of the paper... antibiogram for adequate antibiotic coverage for the different organisms, provide the most common adverse events observed with the therapies provided thus allowing the doctor to have a tool for correct treatment with each consecutive case. With the advancement of technology, healthcare information systems personalize and integrate an increasing amount of information, which has enabled each healthcare facility to function more efficiently. HIS has reduced the cost of healthcare and the rate of misdiagnosis. Additionally, ease the pressure on doctors with easier access to medical records and ease the pressure on the healthcare system as a whole from the price being placed on it. With a growing technology sector, HIS will expand further, allowing the healthcare community to pay more attention to the real problem – patient health..
