In Table II, the standard deviation is proportional to the average and the %RSD is unchanged. Good documentation requires reporting the sample size, average, and standard deviation with the %RSD. The %RSD is misleading when used with data that are expressed as a percentage such as percent recovery. The standard deviation of the data is already in percent. To then find the %RSD is to make the results dependent on the random variation of the average. This defeats the original purpose of estimating the variation of the data values.
Interoperability (pronounced IHN-tuhr-AHP-uhr-uh-BIHL-ih-tee) is the ability of a system or a product to work with other systems or products without special effort on the part of the customer.
Substantial interoperability has yet to be achieved across healthcare, a recent report to Congress from the Office of the National Coordinator's Health IT Policy Committee shows, held up by reasons including lack of standardization and security concerns.
