ACL Services: Scouring the Entire HaystackBy Joshua Weinberger | Posted 2003-08-01 Print

To Catholic Healthcare Audit Network's Jill Linden, ACL "is an incredibly powerful tool. The level of analysis we can do with ACL makes [our findings] hard to dispute." In fact, the power can at times be overwhelming. "If you're doing all this analysis, you're coming up with all these exception reports"—each of which flags a potential anomaly, or a series of transactions that fall outside an expected trend. Every report then needs to be examined. "Clients [sometimes] yell 'Uncle'."
Where Excel maxes out at just over 60,000 records, says BlueCross BlueShield's Clay Cochran, "ACL lets you load any type of file, regardless of the data size. You're basically limited just by your storage capability." Auditors used to look at a small sample and extrapolate. "With ACL, instead of looking at 30 employees, I can look at the entire company," he says. "We've found more errors as a result."
"The closer you are to the raw data, the better," says Meridian's Ralph Wood, "I want the very rawest data—and ACL seems to be able to read anything." But, as with any data-analysis tool, data quality is a constant concern. "If the data's bad, all the analytics will be bad," says HarborView's David A. Less. A series of 12 identical payments could be a problem—or they could just be monthly rent checks, poorly tagged.
ACL empowers auditors to try new things. "We go into an audit for a specific reason," Alcatel's Kerry Shulman says. "But with ACL sometimes you just play around and find unique relationships" that lead to unexpected results. And ACL keeps improving. "Each new version gets easier and easier," Shulman says— ACL 8 "is more like a portal."
Cochran likes that he can "do a lot of the data analysis myself, instead of having to rely on a programmer. I can have a result in 10 minutes instead of having to wait for two days."
ACL's audit log—capturing every keystroke and query—is another popular feature. Useful groups of queries—known as batches—can then be shared with other users, according to Linden. "We never have to build from scratch—we're constantly refining our standard batches."
But some limitations remain. When importing data, Shulman says ACL "can't handle report files with wrapped data over multiple lines," and "will only handle importing one tab per spreadsheet," she says. With multiple tabs, "you have to pre-format a little bit," which she says can take a half-hour of preparation time.
That may be time well spent, if looking for needles in a haystack means spinning the hay into gold. KeyCorp's Fred Sarazin says ACL is directly responsible for bringing back $700,000 in duplicate payments—and for uncovering at least one six-figure fraud.
