Informatics
This implementation improves emergency medicine by using Glass to help clinicians focus their attention on a patient while providing a live visual display of the patient’s vital signs. Clinicians also receive auditory cues to initiate TR&R’s life-saving interventions.
The device can allow leading specialists to connect with hospitals in regional areas or developing countries to provide real-time advice by seeing what that doctor sees.
The NSW Department of Health is responsible for funding public health services, developing policies, managing public health issues and monitoring the performance of the health system. The Health Information Resources Directory (HIRD) project established a database of the information resources currently held by NSW Health. These key information resources include data standards, data collection details, minimum data sets, details about data items in strategic computer application systems and data models.
The HIRD project also provided Internet and intranet access to information models, standards and data definitions, and provided information on all current and past health data collections via a single inquiry point. Dialog undertook the HIRD project from the stage of detailed design through to deployment.
After a separate evaluation process, NSW Health determined that the preferred platform for the data warehouse build was Microsoft. NSW Health appointed Dialog to review the design, build, implement and transition the first release of the data warehouse to production, from established warehouse design documentation and on the given software platform. This project was structured to deliver to the high level requirements for the data warehouse. Dialog’s responsibilities were as follows:
- Build, test and implement Release 1 of the new NSW Health BI data warehouse based on NSW Health selected software
- Provide direct implementation support staff
- Transition the data warehouse into production and BI operations
The Victorian Department of Human Services’ Metropolitan Health and Aged Care Services (MHACS) Division maintains a data warehouse known as the Victorian Health Information Reporting System (VHIRS). VHIRS had a number of operational & functional deficiencies.
In addition to these limitations, VHIRS only catered for acute health data and was not hosted within DHS’ corporate IT infrastructure. As part of the HealthCollect Redevelopment Project, DHS engaged Dialog to assist in the redevelopment of VHIRS as a whole of health data warehouse and to migrate it to the DHS corporate IT environment.
This data warehouse collects data from numerous sources and stores it in a single repository. Dialog was involved in analysing and re-engineering each of the feeder systems and identifying what data needed to be included in the new Data Warehouse. The source systems were:
- Agency Information Management System (AIMS)
- Department of Veteran Affairs (DVA) files
- Transport Accident Commission (TAC) files
Dialog provided expert staff with SQL /data warehouse skills to reverse map VHIRS. This involved specifying all current data transformations, dependencies, and associated business rules that were to be used to define the source-target mapping specifications for the new Data Warehouse. Dialog was also engaged to assist in the design of the Data Warehouse and to confirm the design of the data model.
- A scalable near real-time data warehouse
- Able to operate as part of a hospitals enterprise architecture or in a departmental or research environment
- Able to be federated in a regional or state wide network of data warehouses
- Based on HL7 to capture and stage data
- Internal architecture compatible with the HL7 v3 Reference Information Model (RIM) ensures efficient translation to and from HL7 v3
- Compatible with Open Source research systems
- Able to Support the efficient development of audit data marts for clinical/surgical audit, decision support systems and research
- Designed to eliminate read/write contention, through the use of the near real-time architecture
The basic architecture of the HIF comprises an ETL layer to extract data from transactional systems, then transform and load it via a staging area into the data warehouse. The data warehouse holds the superset of all data extracted from the upstream business systems. Purpose specific, extensible data marts are populated from the data warehouse, according to reporting requirements.
The system is responsible for capturing restrictive interventions applied to clients who reside in accommodation provided by the Disability Services Division. The application is widely used across the state of Victoria. As legislation changes or new requirements arise, the application can be easily updted. The RIDS application is a .NET web based application which uses an SQL database.
The Patient safety screen is a visual display that is available in Theatre that lists the patient’s details, their operation and any allergies that may be important for the surgical clinicians.
The Peri-operative flow application gives the ability for the patient’s journey to be tracked within the hospital.
Austin Health wanted to rationalise and improve the management of referring doctor’s care provider details. In order to do this Austin Health needed to understand where the treating doctor data was stored, updated and which information was up-to-date.
The Dialog team analysed and documented where treating doctor data was stored throughout the hospital systems. The project reported on the state of treating doctor’s data and suggested ways of improving the integrity of that data. The documented business requirements covered the quantity, storage and usage of the data. Dialog also delivered a Gap Analysis and recommended an appropriate solution to implement a single data management solution.
