Hospital Management Information Software (HMIS) Application:
Hospital Information System (HIS) is a major step towards realizing this dream. It has the features to fulfil the objective of streamlining the treatment flow of a patient in the hospital, while providing doctors and other staff to perform to their peak ability, in an optimised and efficient manner.
The state-of-the-art HIS system is modular, thus ensuring sustained benefits through changes in technology, protecting and providing optimal returns on investment. It is modelled on a unique combination of a ‘patient centric and medical staff centric’ paradigm, thus providing benefits to both the recipients and the providers of healthcare.
The aim of HIS is to use a network of computers to collect, process and retrieve patient care and administrative information for all hospital activities to satisfy the functional requirement of the users. It also helps as a decision support system for the hospital authorities for developing comprehensive health care policies.
One of the major objectives of the HIS is to enhance quality of life through an ‘integrated’ computerised clinical information system for improved hospital administration and patient health care. HIS also provides for an accurate, electronically stored medical record of the patient. A data warehouse of such records can be utilised for statistical purposes and for Research.

The Integrated Enterprise Hospital Management Information System (HMIS) consists of various modules. These modules are divided into three major functional areas namely:
• Clinical Module
• Support Module
• Back office Module
Ours is a loosely coupled, modular and integrated HMIS application which can be treated as an ERP for a particular Hospital. Further divisions of each major functional area in the form of Modules and their integration with other Healthcare instruments are depicted as below for ready reference.
• ASTM - Interfaces for Lab Equipments that comply with ASTM.
• DICOM - Viewer for DICOM images.
• HL7 - Capable of messaging and communication with HL7 compliant systems.
• ICD – 10 - Smart Controls for ICD coding of diagnosis details in Clinical Informatics
• BCH - Smart Controls for BCH coding of diagnosis details of Paediatric and cardiology patients.
• CPT - Support for coding the services - Used to describe services in electronic transactions.
A web enabled application that supports Open Source platform with fully-redundant N -tier architecture.
• Browser Based
• Scalable
• Modular
• Central management of business rules
• Platform independent
• GUI Based Interface.
• Workflow enabled.
• Reports (For both standard and Query based).
• Security.
• Authorization & Authentication.
The PACS solution is built on open system architecture. PACS solution is top of the line and independent of vendor or modality. The solution offers facility to seamlessly connect all the present and future imaging equipments in the hospital. The solution is completely modular & scaleable in nature. The PACS network is scaleable to all departments and could be integrated with all the HL7 complied legacy software.
Various Components of PACS
a) Image Server
b) Image Acquisition
The proposed PACS solution includes solution for DICOM acquisition module to acquire & archive all images from DICOM modalities such as CR, CT, MRI, DSA in the Radiology dept.
For Non-DICOM modalities ‘Standard Video Acquisition stations’ are required for archival in the PACS server.
The Scanner Archive Station is connected with the film scanner to scan and archive all films up to A3 size to the PACS server in DICOM format. And regular document/film scanners are included wherever necessary to scan and archive all images such as documents, pressure recorders, ECG etc.
c) Image Archival
All images acquired from various acquisition stations are archived automatically in the server. The Server provides highest data security of three levels. Also patient data is migrated to Long time archival on DVDs.
d) Image Processing
It offers very powerful post processing tools with a very user-friendly interface. All workstations are supported with multi monitor for viewing of color and Black & white monitors. The high resolution monitors of all review stations are built with processing tools such as Window Width & Level, Auto Window, Inversion, Color Schemes, variable filters, Animation with variable speed, Multi image display, Synchronous processing etc., for quick and easy diagnosis.
e) Communication
The proposed PACS components such as Servers, Acquisition module/stations & Workstations/Review stations are compliant to any industry standard switches. Taking full advantage of this, the PACS network will integrate seamlessly in the existing hospital fiber backbone and network infrastructure.
All data transfer within the Hospital’s Backbone network using above infrastructure will be of high-speed loss less image transfer.
Telemedicine Solution:
The objective of implementing Telemedicine Solution is to connect the Peripheral Hospitals with Specialty Hospitals. For this, one-to-one or one-to-many connectivity needs be established between two or more hospitals.
The various components to establish a basic infrastructure would require a scanner, capable of digitizing celluloid films and a Video-conferencing kit. The hospitals would be connected through ISDN connectivity and necessary supportive equipment is to be provided. All the Clinical equipment (e.g. ECG, Microscopes, etc) may integrated to enhance the functionality and capability of the system.
The Telemedicine Solution will enable the Doctors for the tele-consultation and Interaction between Doctor-Doctor and Doctor-Patient. The software will allow acquisition of the patients’ Electronic Medical Record (EMR) directly from scanners. Data can also be entered from existing files, by typing in or by recording audio. In case of pathological reports, data can be entered using interface forms provided for the same. The EMR can be sent across to the Specialist who can browse the data and can create his/ her Expert Opinions. These can be sent back to the Patient-end for appropriate action.
Case Study I
This was a World Bank Funded Project which involves development of application, setting up LAN at labs, Training, Hardware set up at NIC data centre and labs. The number of Labs is 104 spread across the country.
Case Study II
This is a turnkey project which includes Customization and Implementation of Hospital Management Information Software, Hardware supply and Installation, Networking Components User-Training and to provide Facility Management and Support. This is an 18 months project and shall be carried out in Bangalore. The scope of software is like ERP solution for a Hospital and contains all the clinical, non clinical and support modules.
This model shall further be replicated in other Command Hospital across the country.
