Security Assessment
Healthcare is an essential pillar of the society. Governments are using huge percentages of their budgets to avail quality healthcare to their citizens. Furthermore, when patients walk into a medical facility and pay, they expect quality healthcare in return. Healthcare information systems are one of the factors that have significantly boosted the quality of healthcare offered in modern hospitals (Menachemi and Singh 5). This paper discusses some of the common health information systems and how they have impacted the delivery of medical services.
Clinical Administrative Health Information Systems
Almost every department in a health institution processes a patient’s administrative data. For example, the nurse, the pharmacist, and the finance department will use a patient’s personal information such as name and age. Clinical, administrative health information systems are built around electronic patient records, which are patients’ information in digital form (Menachemi and Singh 10).
Clinical, administrative health information systems centralize data entry and processing. Through this, they avoid duplication of administrative data and ensure efficient use of resources. Additionally, with clinical, administrative systems, updating of patient’s records becomes significantly easier than it would have been without a centralized data processing system (Menachemi and Singh 15).
Decision Support Health Information Systems
Decision support systems are mainly used in diagnosis.

These systems are fed with several diseases along with their diagnosis information. With that information, the clinical officers will enter the symptoms observed, and the system will suggest the possible illness. The systems, however, are not entirely relied on; the clinical officers use the system to support the decision they have made in their capacity.
Pharmacy Information Systems
These systems are designed to cater to the needs of the pharmacy department. For example, if the patient is allergic to certain drugs, the information will be obtained from the computerized system (Menachemi and Singh 13-4). Other information in the systems includes the interaction between different drugs and the symptoms that each medicine treats.
Conclusion
Health information systems have brought accuracy and efficiency in healthcare delivery that cannot be possible without integration. For example, the pharmacy system will rely on the administrative system, and the financial administration system will work in collaboration with the pharmacy system. The communication between these subsystems is the critical factor in the delivery of service to the customer and ease of management by the employees and management.
