1 Maria Cinque, Michele Crudele, Giulio Iannello Università Campus Bio-Medico di Roma Hospital Information System for Students The results of the HISS project: an upside- down revolution HISS

2 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 2 Student oriented Students of Medicine, Nursing and Dietetics practicing in the wards were trained to use handheld devices connected through a WLAN to record patients’ data. HISS Università Campus Bio-Medico di Roma September 2003 – July 2004 Funded by HP Grant “Applied Mobile Technology Solutions in Learning Environments – 2003”

3 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 3 Learning and working To teach our students the use of new technologies they will encounter in the future while working in hospitals; To give our students a better tool to learn the medical topics they were dealing in the wards; To define the user interface for medical applications on handheld computers HISS Goals We used the students’ feedback to develop new approaches for a real operational Hospital Information System for handheld computers

4 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 4 Too difficult to achieve We were interested in examining whether the students using handheld computers were achieving better results in their examinations We soon realized that this last goal was too complex to accomplish because too many factors are involved in the learning phase HISS Goals

5 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 5 Challenges Conversion of the written note into an Electronic Patient Record (EPR) suitable for handheld computers Designing of new interfaces for small devices to collect and examine data at the bedside Frequent changes in contents due to users’ feedback HISS Problems

6 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 6 Flexible user-oriented design We developed the structure and contents of EPR studying some existing models and addressing the specific needs of our Hospital To achieve a higher acceptance degree of both teachers and students we used the existing paper models and added predefined answers to make the data entry easier Using a few XML tags we were able to build more than 30 different data entry masks and change rapidly their contents, without rewriting the code HISS Solutions

7 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 7 Technicalities & freedom Since we were not bound to real production and we had no strict deadlines, we were free to try different solutions:  access trough WLAN, GPRS, UMTS;  XML and RDBM;  interface adaptation for pocket and desktop PC’s  on-line and off-line; Actually, we based our system on ASP.NET, C#, XML and SQL Server HISS Solutions

8 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 8 From data to device HISS Architecture Windows Mobile 2003 Windows Mobile 2003 Pocket IE Pocket IE integrated WLAN integrated WLAN DataBase SERVER 3 for each ward 3 for each ward WEP 64 bit WEP 64 bit MAC filtering MAC filtering Win 2000 Server Win 2000 Server.NET Framework.NET Framework IIS 5.0 IIS 5.0 DBMS: SQL Server 2000 DBMS: SQL Server 2000 ACCESS POINT The HISS DB collects basic in-patients data from the actual HIS through a limited read-only access

9 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 9 Multiple wireless networks WLAN, GPRS, UMTS, Mobile IPv6 Management of mobility at the network layer, allowing network applications to be unaware of changes in the network Easiness of use and configuration and seamless roaming: the user does not need to change anything moving from local to geographic wireless access networks HISS Architecture

10 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 10 From XML to the device HISS Interface

11 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 11 User oriented Drop down or check lists Multiple sections masks  avoiding long pages Frequently used options  easily accessible Additional text boxes  three sizes HISS Interface

12 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 12 Students collecting records Bedside data collection  anamnesis, requests for specific examinations (medicine students)  collaborations problems, calculation of fluid balance (nursing students)  patient appreciation of hospital food, daily change of diets (dietetics students) Technical work  set up hardware and software, help desk, usage monitoring (bioengineering students) HISS Data

13 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 13 Participants & records 110 students 495 medical records 243 nursing records 193 dietetic records (+ 919 by tutors) 1500 patients 30 different tasks HISS Numbers

14 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 14 Dietetics students positive comments Speed in finding the answers Time spared in the transcription of data from paper to PC Usability The palm computer does not need a stand and it is not “uncomfortable” HISS Feedback

15 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 15 Nursing students accuracy The students using handheld devices for data entry in structured masks were more accurate than those writing on a blank piece of paper They noticed more things (having different questions to answer) and they were more precise HISS Feedback

16 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 16 Medicine students rejection First extensive phase Rejection by many students because of rejection by their tutors in data entry Second intensive phase Limited to those departments that showed a positive attitude: cardiology and general surgery HISS Feedback

17 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 17 Open issues and future Enhancing the hospital level of technology by improving the accessibility to the HIS at different levels through mobile technologies Improve teaching and learning in the wards through faster access to clinical data Designing new interfaces for small devices to collect and examine data at the bedside Deeper comprehension of security issues HISS Issues

18 Learning Communities in the era of Ubiquitous Computing Milano – June 13, 2005 18 Source of new activities The Dietetics department adopted the interface produced by the students: a new production application was developed achieving 35% time gain Enhancing communication in the surgical ward: a new research project started Project extension funded by HP for the next year (MoPS Project) HISS Outcomes
