Introduction



Radio-frequency identification (RFID) is an automatic identification
method, relying on storing and remotely retrieving data using devices
called RFID tags or transponders.
RFID is proving to be one of the best solutions for tracking and identifying
assets around the world.
It can be used to locate items, monitor animals, provide quick
identification and tracking medicines in the hospitals, it also can be
deployed in various spheres for tracking and managing movable assets.

Example of a Digital Community:
Transformation Story
Bumrungrad Hospital, Thailand


554-bed facility
Over 960,000 outpatients/year (2003)
Optimize workflow
 Patient data, administrative records
 All documents electronically input
 Digitized medical images -- available promptly in doctor’s
offices
 All HIS integrated on one Application Platform and Database
Results:
 40% growth in outpatient volume without adding IT overhead
(3k patients/day)
 Patients processed in 45 minutes from registration to
prescription pick-up
 33% gross profit margin
 All medical images archived on one server  file storage room
converted to profitable children’s clinic
Terminology and
Standards.
 Radio Frequency Identification (RFID) is a method for remotely
storing and retrieving data using devices called RFID Tags or
Transponders.
 RFID tag is a small object, such as an adhesive sticker that can be
attached to a product, these tags are composed of and antenna
connected to an electronic chip, these chips transform the energy
of radio frequency queries from an RFID reader or transceiver to
respond by sending back information they enclose.
 Finally, a computer hosting a specific RFID application or
middleware pilots the reader and processes the data.
 The Electronic Product Code ( EPC) uniquely identify objects and
facilitates tracking through out the product’s life cycle.
The infrastructure of RFID enhanced hospital
“Smart Hospital”
First :- Many assets and actors of the facilities have to be “ tagged”.
 Medical equipments ( must embed RFID tags by the manufacturer).
 Hospital’s staff members wear “ smart badge” storing their employee ID
numbers.
 Each patient wearing a waistband with embedded RFID tag storing some
information about him ( e.g. digital picture, unique patient code,… etc).
 All patients medical histories and other important documents are tagged
with self-adhesive RFID labels containing a unique number.
 All drugs’ packages and bags of blood contains RFID labels, holding unique
identifier and important information about the type of the blood.
Second :- RFID readers are placed at strategic places within the hospital.
 At the entrance and exits of the hospital.
 Each operating theater contain at least one RFID reader.
 RFID Sensors are placed in strategic galleries and important offices.
 The Staff member, each have a handheld ( PDA, mobile phone, etc.)
equipped with an RFID reader and possibly with a wireless (e.g. WiFi)
connection to the web.

RFID Device Selection criteria:
Analysis/feasibility Study.
. What are the objects to be tagged?
· What are the objects made of and how do they affect reading
ranges?
· What are chip antenna types?
· What readers can read both passive and active tags?
· What readers can read both RFID tags and bar code labels for
easy transitioning?
· What are other considerations that could affect externally the
optimal location of tags?
· How do various entities organize frequency types or ranges?
· What other standards are the vendors using for their RFID
products?

Implementation issues & Project plan for Smart
Hospital
In order to complete the project of Smart Hospital, we need;
1- Software engineering team:- To develop a middleware program application, to
integrate data in a common format with enterprise system, this middleware
should be a scalable and robust distributed application, also a web based
application connecting all the information gathered by RFID reader with a
database server.
2- Network Engineering Team:- Since the Smart Hospital RFID architecture having
wireless network connection, to integrate and store all data and information
gathered from different RFID readers in database application servers and webservers, so we need team of network engineer, for the purpose of wireless
connection troubleshooting and installations.
3- Electrical engineering Team:- To specify the best RFIDs’ tags and readers
specifications for this project and installing them in a way to maximize the
benefits of applying this project with the minimum costs.

A list of RFID Middleware Providers are as follows :Acsis, Blue Vector Systems, Conne Terra, EPC global, ….. Etc.
2- Main suppliers for Active RFID products including RFID tags and
readers are:- Lien Technology, Axcess, Escort Memory System, Microtec, Samsys, ……
Etc.
Challenges & Problems
There are still open problems to be solved before the healthcare
community fully embraces the RFID technology:1- The Radio Frequencies interferences between the medical electronic
devices in the hospital, we suggest here to use radio-frequencies anticollision algorithm.
2- The Privacy & Security issues are also open problem here, since there is a
possibility of unintended wireless transmission of healthcare-related
information, the suggestion here is to use a challenging cryptographic
algorithm for secure wireless transmission of the important healthcare
information.
