2 ABC of Medical Computing Topics Computing Basics What is a computer terms networks connecting it all together (WWW,WAN,LAN) Applications local and centralized Account management security, authentication and your profile Discussion of the Clinical system network architecture, governance model and change management On the horizon hand held, radio-frequency identification (RFID), facial recognition, remote access MB Health / eHealth and WRHA Services project management, service desk, work orders, H/W S/W upgrades

3 ABC of Medical Computing What do computers have to offer? The common reason for buying a computer is the need to write simple letters, medical reports, papers - a word processor but they can do much more. Computers are good at storing and manipulating large amounts of information. Database programs collect, sort, and analyze and perform repetitive tasks extremely fast and without error. General practitioners computerize their practices which offer comprehensive recording of medical records, issue repeat prescriptions, and provide call and recall facilities. Hospitals have many computer systems for Admitting, Scheduling, Lab systems and PAC,s to name a few. These systems make it possible for us to build the Electronic Health Record (EHR) giving authorized healthcare providers rapid access to patients' complete, up-to-date health information to support clinical decision-making and case management.

4 ABC of Medical Computing Computer Basics Computers are everywhere you look, and even in places you can't see. Computers check out your groceries, pump your gas, dispense money at the ATM, turn the heat on and off in your home There are different kinds of computers for different purposes

5 ABC of Medical Computing Computer Basics What is a computer? A computer is an electronic device that executes the instructions in a program. A computer has four functions: a.accepts data as input b.processes data c. produces output d. stores results - storage

6 ABC of Medical Computing Computer Basics Types of Computers Computers for personal use come in all shapes and sizes PC (personal computer) –Desktop or referred to as a workstation –Laptop provides mobility –Tablets you use an electronic stylus to write on the screen PDAs (personal digital assistant) –Black Berry or Palm Pilot

7 ABC of Medical Computing Computer Basics Terms Hardware –the physical parts of the computer Software –the programs (instructions) that tell the computer what to do Data –individual facts like first name, price, quantity ordered Information –which has been massaged into a useful form, like a complete mailing address CD ROMs –(compact disks read only memory) Similar to the audio compact disc, are an excellent way of distributing large amounts of information

8 ABC of Medical Computing Computer Basics Terms Network –A network is a set of computers which are linked together on a permanent basis. This can mean two computers cabled together on the same desk, or thousands of computers across the world. Internet –global computer network: a network that links computer networks all over the world by satellite and telephone, connecting users with service networks such as and the World Wide Web Intranet –computer network within organization: a network of computers, especially one using World Wide Web conventions, accessible only to authorized users such as those within a company Firewall –similar to firewalls with fire door in building construction. In former case, it is used to prevent network access and intrusion to the private network

9 ABC of Medical Computing Computer Basics Terms Server –The term server refers to a specific kind of computer. –It handles the sharing of equipment like printers and the communication between computers on the network. –A computer somewhat more capable than a personal computer which requires more power, larger memory & storage capacity with high speed communications Main Frame –A main frame allows hundreds of people to work at the same time on the same data. It requires a special environment - cold and dry, backup power. Storage –May be referred to as storage area network ( SAN ) providing data storage on a local disk or a network connected device such as disk arrays, tape libraries.

10 ABC of Medical Computing Network s In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. Networks can be categorized different ways. Usually defined according to the geographic area it spans. Local area networks (LANs)Local area networks (LANs), typically reach across a single home or office Wide area networks (WANs), reach across cities, states, or even across the world.ide area networks (WANs) The Internet is the world's largest public WAN.Internet

12 ABC of Medical Computing Application Local and Centralized

13 ABC of Medical Computing Account Management security, authentication and your profile Passwords – the Weakest Link in Healthcare Security The temptation for users to share passwords is high. Policies such as 90 day auto reset with a rule based on no repeats has been a challenge to adopt The more complicated the password policy, the more expensive it is to implement and support. Between 25 and 50 percent of calls to help desks are for password resets. Deloitte & Touche estimated that the typical enterprise spends an average of $150 per user, per year to support password resets.

14 ABC of Medical Computing Account Management security, authentication and your profile Why do we need account management? Security Trustees must protect personal health information by making reasonable security safeguards to ensure the confidentiality, security, accuracy and integrity of the information Authentication Identifies the user Allows for auditing Defines privileges Profile Categorize types of users based on their job roles within the organization into profiles that can be assigned to multiple users performing the same job.

15 ABC of Medical Computing Clinical System Network Architecture – many systems are designed for a specific purpose, typically the application will define the architecture. Hardware – systems get old and from time to time need an upgrade Applications require added functionality or regulatory changes Governance – How do we manage change to work flow? Who will participate in the approval as we implement provincial services/applications How are they implemented – project or a work order / impact assessment Change Management – How is the change request managed? Best practices (ITIL) include change, release and incident management processes

16 ABC of Medical Computing Clinical System Network

17 ABC of Medical Computing On the Horizon Hand Held Devices - The use of these devices to access medical literature and education, research, e-prescribing as well as specialty-specific uses for personal digital assistants (PDAs). Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags. It can also be used to locate staff and patients within a facilityautomatic identification A recent survey (BearingPoint) established that RFID technology is being used for a wide variety of applications within health-care organizations, including patient flow management, access control and security, supply chain systems You are here

18 ABC of Medical Computing On the Horizon Biometrics Vendors and Solutions Fingerprint &Hand Facial & Iris Voice & Smart cards Fingerprint-based identification is the oldest method which has been successfully used in numerous applications. Everyone is known to have unique fingerprint. Facial recognition - software has come a long way. It can pick someone's face out of a crowd, extract the face from the rest of the scene and compare it to a database of stored images. Smart Cards defined as pocket-sized card with embedded integrated circuits which can process information. The card is made of plastic, just like any bank card.

19 ABC of Medical Computing On the Horizon Remote Access - anywhere any time Healthcare industry is looking at secure remote access solutions. Growing number of healthcare professionals believe that it will provide improved data accuracy, reduce errors, and result in an overall improvement of patient care. A team of radiologists deliver a 24-hour on-call service. Unable to access patient x-rays from their homes and, consequently, spent a lot of time traveling to hospitals. Secure remote access solution, the radiologists can work from remote locations, reduce travelling time, and deliver urgent reports quickly. The Manitoba First Nations Remote Access Initiative Aimed at demonstrating the value of remote, dynamic access to knowledge and health human resources. Involved 35 First Nations communities, Tribal Councils and their health services organizations;

20 ABC of Medical Computing MB Health / eHealth and WRHA Service Health care initiative are much like any other business. Funding is provided in several ways, treasury board, infoway or grants. Project management, depending on the initiative may be provided by MB Health, Manitoba eHealth or the WRHA delivering services such as RIS/PACs / Electronic Health Record and Client Registry. Manitoba eHealth has centralized a service desk as a single point of contact and working with the RHAs on a shared service model in anticipation of provincial initiatives. Adoption of new systems and h/w s/w upgrades are becoming a fact of life, some are easy some are very complex. What makes all of this work, is when we can all work together and better understand the risks and impact and I hope to see more interest in participating together in the future – we will all benefit regardless of roles, service support, care givers and patients alike.
