Developing a Computer-based Hospital Information System - Noel Lawas MD -

Session Objectives At the end of the session, you should be able to: Summarize the framework in developing the hospital information system Discuss the various steps that are relevant to hospital administrators Describe the data model and its significance Discuss the implications of computerization to management system change. Discuss the role of HRDO in the process of computerization.

Systems Analysis Examines the existing operating procedures in providing services and how well they comply with regulatory requirements Examines the gaps in the existing SOPs resulting in suboptimal level of effectiveness and efficiency of its services Identify duplication of responsibilities Assess the readiness of the responsible persons to cope in an IT environment Result of the analysis: overall system design recommendations back

Identify IT Interventions to Adopt Presently, IT interventions come in the form of computerization Most recent developments is in web technologies Immediate future may be in the use of smart phones, ipads and itouch that can connect to the internet seamlessly Be cautious in permanently replacing existing processes with new IT technologies back

Designing the Hospital Information System The first two steps serve to prepare the way to the decision whether to computerize or not. If the hospital decides to computerized, identify the areas to computerize in the hospital (both clinical and non-clinical) within the next ten years. Design a master plan for it and decide its development in phases

Designing the Hospital Information System Hospital managers identify service transactions within functional units of the hospital to be computerized Systems developers and programmers should provide the framework for the eventual interconnection of these service transaction processes. The master design should already include provisions to generate pre-identified information which should belong to any of the following categories: Information on transactions and services delivered Information to support executive management decision making

Designing the Hospital Information System The master design takes the form of a data model. A data model is a creative work which identifies the database tables that should be created together with their data fields plus how important tables shall be linked to each other for the purpose of maximizing its information generation potential.

Explaining a Data Model A data model is a schematic representation of data records contained in tables where linkage between tables are accomplished through creation of the same data field in both tables. Data model is implemented through the use of SQL Language With linked tables, any number of data fields can be extracted from the two tables to created new records.

Planning for Deployment and Utilization Introducing computerization is a major change in the management system With automation, it should reduce manual work load with minimal increase in new tasks With automation, it should reduce the number of decision points made by man in a transaction With automation, availability of data can easily overwhelm an individual especially those not used in handling voluminous information

Planning for Deployment and Utilization Therefore, there is a need for the HRDO to be ready in modifying the job descriptions and reassessment of key performance targets. On the part of management, this is the best time to plan to readily make available critical information, generate and utilize them. back

Information Systems Development (Technical discussion beyond expectations for Master of Hospital Administration students.) - Covers systems programming, networking and database administration back

Human Resource Development Pilot testing a newly installed hospital information system is not meant for debugging alone. It is also intended for the users to slowly adopt, adapt and be adept with the system. Users training should be intensive combining classroom with individual mentoring if needed. Management should be strong willed to continue in the face of cries, curses, shouts, etc. Thus, management should have no doubt that the systems developers are doing the right thing. back
