Designer's Aid for Infusion Pumps to Minimize User Error. Completed
research and developed a computer-based design aid that to minimize
errors during the operation of infusion pumps. As part of the system
development, a nationwide survey of nurses was conducted to examine
sources of human error in the use of medical infusion systems. The
survey determined (1) types, severity, and relative frequencies of
error, and (2) the factors that ultimately lead to error in medical
settings (i.e., operator, equipment, environmental, organizational,
and social factors). In addition, laboratory experiments were conducted
to investigate cognitive sources of user error in the use of medical
infusion pumps--nurses' mental models of how infusion pumps work,
and working memory overload while using an infusion system. (National

Preference Testing of I.V. Infusion Pump Operating Manuals.
Performed research comparing user preferences for a home infusion
pump manufacturer's manual and a manual we developed and wrote using
FDA's Write it Right.. Comparative follow up testing utilizing actual
and potential users of home infusion pumps revealed a clear preference
for the manual we wrote using these recommendations. (U.S. Food and
Drug Administration)
Human Engineering Services to Support Design of a ICU Bedside Equipment.
Performed human factors analyses to support the design of microprocessor-based
ICU bedside unit. Performed a detailed task and subtask analysis of
user functions and assessed the design implications of the task analysis.
Identified display and control technologies for the operator interface,
recommended a user-computer dialogue structure, and developed recommendations
for system configuration and layout. Developed extensive sample screen
layouts to illustrate user interface concepts, mode transitions, and
display content, information and format. (Project work performed for
a major biomedical manufacturing firm)
Human Factors Seminar for the FDA. Conducted a four-day seminar,
"Fundamentals of Human Factors for Engineering and Design" for the
Center for Devices and Radiological Health of the Food and Drug Administration.
Seminar topics included: the human factors model of information processing
and performance, task analysis, principles of display control design,
human-computer interface design, principles and criteria of layout,
and test and evaluation methods. Each topic included a practical exercise
to provide an opportunity to practice the principles and techniques
presented. (U.S. Food and Drug Administration)
Workshop on Human Factors Principles & Standards for the FDA.
Developed and conducted a workshop on human factors principles and
standards for the Center for Devices and Radiological Health of the
Food and Drug Administration (FDA). The workshop was designed for
FDA representatives who participate in the development of standards
for the design and manufacture of medical devices. The objective of
the workshop was to provide a basic understanding of human factors,
present human factors principles applicable to the design of medical
devices, and provide practice in addressing human factors issues in
design problems. (U.S. Food and Drug Administration)
Design of an Environmental Test Kit. Conducted user analysis
and applied human factors engineering principles to the design of
Quik-Screen test kit for detection of toxic substances in fluids.
Designed the test card, user instructions, and test-kit packaging.
The kit subsequently gained extensive user acceptance among agriculture
inspectors. (Environmental Diagnostics, Inc.)
Research on Aiding Physician's Decision. Research determined
the feasibility of a sophisticated system for retrieving statistical
data about risk and prognosis to aid physicians' decisions whose practice
includes breast cancer patients. The research used a survey methodology
to determine practicing physicians' statistical environment, including
their training, their perceived need for and attitudes about statistical
data, and their use of computers and computerized data bases. Data
was used to characterize the responding population and identify potential
barriers to physicians' use of computerized data retrieval and decision
systems. Results were used to develop guidelines for a user interface
for such systems, with particular emphasis on compensating for the
identified barriers. (National Science Foundation) |
