Work measurement in pharmacy research.


The applicability of various methods of work measurement to pharmacy research is discussed, and studies that have used these methods are reviewed. Methods of work measurement include subjective evaluation, direct time study, work sampling, statistical data, and pre-determined data. Subjective evaluation lacks precision in its estimates but may be useful in formulating hypotheses. Direct time study is most appropriate for readily observable, highly repetitive tasks that can be divided into short segments, although it has been used for longer and more variable activities. Work sampling is the most frequent method of work measurement used in pharmacy research, but few studies reported doing any check of measurement reliability or validity. Multidimensional work sampling and other forms of direct-entry, self-reporting work sampling may be useful in measuring the more complex and unobservable tasks of pharmacists such as clinical activities. By developing an understanding of the purposes and applications of measurement techniques, hospital pharmacists can choose the most appropriate method for their research setting and purpose.
