History of Health information System and Clinical Applications

History of Health Information System

Health sector and information technology have undergone severalchanges in the recent past. In 1960s healthcare was drivers in thisperiod were Medicaid and Medicare. The information technology driverswere high storage and mainframes. These storage and computers were soexpensive and extensive. The mainframe was being shared typically byhospitals. Hospital accounting systems were the key applications thatemerged in this environment. The 1970s, healthcare drivers at thistime were needed to do a high-quality job in communicating betweendepartments. During this era computers were must smaller in size. Itmade them easier to be installed in the single unit without anyenvironmental control at all, hence led to distinct departmentalsystems such as pharmacy, clinical and pharmacy. The 1990s, in thisperiod, consolidation and competition drove healthcare towardsmanaged care, providers and the need to ingrate hospitals. Hospitalsduring this time had access to active networks, spread computingsystems, and a broad one. Therefore integrated delivery network (IDN)was created to integrate with one another, for example, reporting andthe impetus to ingrate data. In the 2000s, there was enough bedsideclinical applications and technology installed. They were intended toenable a concurrent clinical decision support and run at commercial.Healthcare drivers in this period were outcome-based reimbursement,and integration (Grandia, 2016).

Health information know-how has a wide collection of technologiesthat involves in sharing and managing patient data electronically.These technologies have the ability to improve patient datacollection, efficiency, patient safety and health care quality(Takvorian, 2016). Basically, in administrative, theseclinical information systems and applications help a lot in providingcomprehensive healthcare, for instance, inpatient administrationsystems. Admission, transfer registration, and discharge of thepatients are technologically by the use of Health informationtechnologies. It will provide comprehensive care to the patient.Utilization management and patient billing in the hospitals willbecome efficient. In financial management systems for examplepayroll, accounts payable and general ledger allows for the smoothrunning of the hospital. Hence doctors and other staffs will receivetheir salaries on time.

For comprehensive care, clinical applications have to be put inplace apart from the administration applications. With awell-equipped lab, definitely with medical information systems likecomputerized physician order entry (CPOE). It is an essential part ofelectronic health record system (EHR). The system allows the doctorsto array prescription drugs and laboratory tests digitally. Therebyeliminating errors linked with unreadable handwritten laboratorytests results and prescriptions. So the CPOE systems for reading labtests and prescriptions reduces clinical care errors by ensuring thatorders are entirely readable. Other clinical information systemincludes Electronic medical record, nursing documentation,telemedicine service documentation and medication administration(Glaser, Lee, &amp Wager, 2013). They will work together forcomprehensive care.

Benefits of Healthcare Information Technology

Clinical information technology improves the quality of thehealthcare. The increasing number of health caregivers offerspatients the capacity to manage and store their individual recordssecurely online. Group by now uses private document managementservices with complex medical conditions.

Gone are the days when the laboratory tests and prescriptions wereillegible. Due to Ancillary information systems, the errorsassociated with the unreadable handwritten lab results andprescriptions have reduced. Movement of the patients has become smallwithin the hospitals. They can be retrieved in any department withinthe hospital without necessarily moving around. The majority of thesesystems are life serving machines hence a reduction in death cases.

Challenges of Healthcare Information Technology.

The primary problem of the clinical information technology is privacyand security concerns. For it to be deployed successfully forrelevant efficacy research, health records are distributed in healthdata network. There is also genuine concerned about government accessto the information. These will make the patient lack trust with theseclinical technologies.

Malwares are another form of threat to these systems. Computers usedin these systems may be corrupted by the malware hence losing a lotof data. Which might not be retrieved and that will mean incurringextra expenses to have the records back (Ammenwerth, Gräber,Herrmann, Bürkled, &amp Königb, 2013).
