Design and implementation of a real-time clinical alerting system for intensive care unit.

Nowadays many hospitals use clinical information systems (CIS) to improve patient health care and information management. CIS retrieves and manages patient information such as patient administration, laboratory data and medications. Specialized CIS, especially Intensive Care Unit (ICU) CIS, needs to handle more additional information. How to process and make use of this enormous amount of physiologic data generated by ICU is a significant topic in CIS design. We have designed and implemented a real-time clinical alerting system for ICU, which executes alert algorithms on the database records of 63 ICU physiologic parameters. The user can create various alert rules with our rule editor to supervise the values or trends of these parameters. When an alert condition on a specific patient is detected, the system notices the clinicians in charge with mobile phones or pagers. With this functionality, up-to-date patient information is provided for clinicians inverted exclamation mark | use in judging the patient inverted exclamation mark |s condition and making treatment decisions.

Technical and structural support systems and nurse utilization: systems model.

There are two major components to nursing support systems: technical support systems, for the distribution of supplies and medicines to patients and for communication among hospital personnel, and structural support systems, for the organization of nursing staff-RNs, LPNs, and aides-into a systematic, working assignment pattern. Four hospital studies that used different combinations of technical and structural support systems were compared for the amount of time registered nurses were able to spend on direct patient care activities. It was found that a structural support system based on the primary nursing model, coupled with a decentralized technical support system, maximized direct patient care time.

A user-oriented protocol for integrating heterogeneous communication systems of medical facilities using ports.

The crucial feature of future communication systems in hospitals will be the heterogeneity between the individual systems. People working in a hospital do not communicate via data objects, but via highly complex functions like preparation of a patient report or diagnosis of patients' symptoms and signs. Essentially such tasks are accomplished by initiating remote functions in various modes of a communication system. The aim of the MEDAS protocol developed by our group is to propose a definition of such a high-level medical protocol and then to implement it. Our user-oriented protocol permits information exchange between heterogeneous systems. Modules and functions are defined. Message passing to and from a processor is realized using ports. The protocol sequence of every communication request is described. The relation of ports to the ISO model is specified. First experiences in a network for a medical school are reported.

The power of picture archiving and communication systems: strategic hospital considerations.

As healthcare information becomes more digitized, hospitals are adopting critical diagnostic tools to improve patient care decisions, while reducing errors and increasing overall efficiency. According to Radiology (2000), 75 percent of the imaging procedures performed in 1995 used devices that were not available in 1970. Today, imaging applications continue to move from research and development into common use each year With regard to digital imaging, Picture Archiving and Communication Systems (PACS) perhaps have changed radiology more than any other application in the past few decades. Once regarded as "nice-to-have-but-too-expensive" devices, PACS are rapidly moving into the mainstream of "must-have" solutions for quality-conscious and forward-thinking hospital CEOs. However, before widespread implementation of PACS can occur, several critical factors should be taken into consideration.

Developing a video-mediated communication system for hospitalized children.

When a student is away from school for an extended time due to illness, he/she is provided with a tutor or access to in-hospital classrooms to keep up with his/her studies. This isolates the child from normal classroom experiences. A remote-control videoconferencing system (VCS), P.E.B.B.L.E.S.trade mark (Providing Education by Bringing Learning Environments to Students), was developed to allow a student access to his/her regular classroom from the hospital. Remote control is provided by a game pad, which allows the student to direct the system. The first iteration, P.E.B. B.L.E.S. I, tested feasibility. The design of P.E.B.B.L.E.S. II provides an integrated version of the system with user interface aimed at children. Four studies examined its efficacy in allowing a student to participate in typical classroom activities and in providing him/her a sense of presence in the classroom. Results indicate that the system can be used with relatively few errors when set to perform the majority of required activities. The study-participants reported positive experiences using the system, and remote users appeared to have a sense of presence in the classroom.
