¶ … data mining techniques in a healthcare data warehouse" by Silver (et al.) deploys a case study approach to examine how data mining can be used in clinical support systems to reduce costs in an increasingly cash-strapped healthcare environment. The specific focus was upon unprofitable DRGs [diagnosis-related groups] and attempted to discern the negative financial impact of specific types of Medicaid and Medicare patients upon a facility (Silver et al. 2001, p. 159). The study utilized online analytical processing (OLAP) tools to facilitate effective data mining techniques. Two techniques for data mining were involved: patient rule induction method (PRIM) and weighted item sets (WIS). The latter is a type of statistical associative technique used to find relationships between seemingly unrelated sets of data.

WIS is used to find general associations, and thus it can be difficult for computer neophytes to use because the conclusions are not self-evident, while PRIM directly "calculates a subset of data points with the highest average value, given a set of input attributes and a minimum size of the region specified by the user" (Silver et al. 2001, p. 157-158).Get full Download Microsoft Word File access

However, according to the authors, finding unexpected relationships can often be more fruitful than pre-determining what types of associations to make with the data sets. The central problem, as determined by preliminary PRIM analysis using "loss" as the output variable found that the average loss associated with the inpatient visits in the hospital region was seven times larger than the inpatient visits outside the region and average length of stay for the inpatient… [END OF PREVIEW] . . .
