This is a three page summary with bullet points. It is a summary of some research that is written by a student on ergonomics. The issues discussed include research methods in ergonomics, as well as the results of that research. The focus is on the health care environment, as some of the studies are about neonatal care unit lighting and how the lighting affects infants.
Ergonomics
The relation of Ergonomics and Anthropometric Methods & Health Care setting design
Four (4) Main Parts of Research Methods and Design in Ergonomics:
Research relationship with people's study (theory and hypothesis)
Site selection and sampling decisions (setting and population)
Data collection methods (survey, measurements)
Data analysis types and techniques (statistical analyses)
Three (3) different research methods
Descriptive
Can be qualitative or quantitative
Descriptive statistics tell "what is,"
Different from using inferential statistic
Pure fact, no relationships between cause, effect
Assess magnitude or scope of problem and suggest ideas for future research
Experimental
Manipulation of variables
Scientific Method
Use to determine causal relationship or significant correlational relationship
Evaluation
Shares elements in common with experimental and descriptive
Examines system or product
Describes relationship between subject and the system/product
Research with regards to ergonomics in health care environment: Keypoints
Case1: The Role of Qualitative Methods in Designing Health Care Organizations
Hospitals not always designed with ergonomics in mind
Need more research
Case 2: The physical environment of the person with Alzheimer's disease
Behavioral observations very helpful as a research method
Individual affect observation (watch emotional responses)
Case 3: Implementation of Cycled Lighting in a Single-Room Neonatal ICU
Good illumination needed in health care
Concept of critical care area (environmental factors in clinical environment)
Sleep disturbances in patients are caused by noise, lighting, patient care activities, vital signs, phlebotomy, and medication administration during the night
Nursery lighting has impact on infant development in neonatal care
Difficult for staff in health care to break old habits
Compliance easiest with night shift nurses
Need for dimmer switches
Importance of positive feedback for nurses to encourage proper lighting procedures.
