Comparative Study
Location tests for biomarker studies: a comparison using simulations for the two-sample case.
Gene, protein, or metabolite expression levels are often non-normally distributed, heavy tailed and contain outliers. Standard statistical approaches may fail as location tests in this situation. ⋯ The standard U-test was a powerful and robust location test for most of the simulated scenarios except for very heavy tailed or heavy skewed data, and it is thus to be recommended except for these cases. The non-parametric adaptive tests were powerful for both normal and non-normal distributions under sample variance homogeneity. But when sample variances differed, they did not keep the type I error level. The parametric adaptive test lacks power for skewed and heavy tailed distributions.

Comparative Study Observational Study
Caregivers' time utilization before and after the introduction of an electronic nursing documentation system in a residential aged care facility.
Despite increasing research on caregivers' interaction with technology, there has been no attempt to investigate how the introduction of an electronic system in a residential aged care facility (RACF) may affect caregivers' use of their time. ⋯ It may take over a year for some caregivers in an RACF to integrate the use of a newly introduced electronic documentation system into their daily work. Organisations implementing such systems should develop strategies that support and accelerate the caregivers' integration of the new documentation practice into their routine activities. The electronic documentation system may not however, replace the role of verbal communication between caregivers in aged care service.

The World Health Assembly (WHA) of the World Health Organization (WHO) and three of the six WHO Regional Committees adopted a number of resolutions on eHealth: the use of information and communication technology for health. These resolutions have given legitimacy to eHealth as an area of work for WHO and its member states. The implementation of these resolutions will contribute to the achievement of the Millennium Development Goals (MDGs) and the Universal Health Coverage. eHealth has been perceived as reducing the cost of healthcare, improving quality and equitable access to health services.
