Comparative Study
Comparison of three established measures of fear of falling in community-dwelling older adults: psychometric testing.
Several approaches have emerged for measuring self-reported fear of falling. A comparison of measurement scales' psychometric properties is needed for researchers to choose the proper scale for their study. ⋯ The FES, ABC and GFFM demonstrated strong internal consistency reliability. The GFFM had stronger associations with physical and psychosocial functioning and may be more appropriate for studies focused on improving all aspects of fear of falling. Both FES and ABC instruments demonstrated ceiling effects, which may explain the lack of responsiveness to change in relatively non-frail older community-dwelling adults. Instruments sensitive to measuring lower levels of fear of falling are needed to capture the full range of this phenomenon in this population.

Comparative Study
Nurse-determined assessment of cardiac output. Comparing a non-invasive cardiac output device and pulmonary artery catheter: a prospective observational study.
The accurate measurement of Cardiac output (CO) is vital in guiding the treatment of critically ill patients. Invasive or minimally invasive measurement of CO is not without inherent risks to the patient. Skilled Intensive Care Unit (ICU) nursing staff are in an ideal position to assess changes in CO following therapeutic measures. The USCOM (Ultrasonic Cardiac Output Monitor) device is a non-invasive CO monitor whose clinical utility and ease of use requires testing. ⋯ In 80% of our cohort, USCOM, PAC and Fick measures of CO all showed clinically acceptable agreement and the learning curve for operation of the non-invasive USCOM device by an ICU RN was found to be satisfactorily short. Further work is required in patients receiving positive pressure ventilation.

Comparative Study
A comparison of novice and expert nurses' cue collection during clinical decision-making: verbal protocol analysis.
The type of cues used during clinical decision-making contexts is not well understood. Further, there are conflicting findings in relation to how novice and expert nurses use cues. ⋯ In the real world of practice expert nurses collect a broader range of cues to assess patient status than novice nurses. This differs to expert nurses cue collection in simulations where expert nurses may select only those cues that are necessary for the identified problem. This difference, if identified in other studies, may have important implications for nursing research and education.

Measurement error can seriously affect the validity of pressure ulcer risk assessment and of pressure ulcer classification. ⋯ The standardized study procedure applied in the annual nationwide pressure ulcer prevalence surveys leads to reliable and reproducible results regarding pressure ulcer risk and pressure ulcer prevalence in the home care setting. Researchers and practitioners should be careful when drawing inferences from single pressure ulcer risk factors included in the Braden scale. Descriptions of the items "moisture", "sensory perception" and "nutrition" should be made more clearly and unambiguous.
