Applying Identity Resolution to Patient Identification Integrity

Wednesday, August 5th, 2009

By Robert Barker, Infoglide Senior VP & Chief Marketing Officer

The recently passed economic stimulus plan included $20 billion to encourage adoption of electronic health records by medical facilities across the U.S., spurring a huge amount of activity in the health care world. Implementing electronic medical records (EMR) is a very hot topic!

A key issue in EMR implementation is the integrity of the patient identification process used in creating an enterprise master patient index (EMPI). Avoiding medical errors means avoiding multiple types of errors that can crop up. Duplicates are a simple example, where the two records exist for the same person within a single facility. More complex types of errors can easily start to mount up, including overlaps where more than one record exists for one person within two facilities within a single organization, and overlays where information for two people are integrated under a single record.

False positives and false negatives during the identification process often cause these types of serious errors. Beth Just of Just Associates recently wrote an AHIMA Practice Brief entitled Managing the Integrity of Patient Identity in Health Information Exchange:

Common pitfalls include linking two closely related people with very similar names and dates of birth who live near each other (e.g., cousins who are named after the same individual who recently expired); two individuals living in a dense urban area with the same common name, date of birth, and address; or the example of twins having the same first name. Failure to catch such errors can result in overlaid medical records and subsequently negative health outcomes, serious privacy breaches, and legal ramifications.

Entity resolution technology capable of handling these problems has evolved in response to similar challenges that arose in other industries. Disparate applications, including airline passenger screening, lottery retailer fraud detection, organized retail crime fighting, and workers compensation fraud discovery, employ the same technology vital to successful EMR implementations.

Liliendahl on Data Quality: Master Data meets the Customer

“When doing business online with multi national customers then take care that the sequence, formats and labels are useful to everyone and that mandatory checks and other validations are in line with rules for the country in question. External reference data may be used for lookup and validation integrated in the registration forms.”

FBI Charlotte: Seven Charged with Terrorism Violations in North Carolina

“‘The cooperation between federal, state and local authorities throughout this investigation has been outstanding. It is only with our ongoing law enforcement partnership through the Joint Terrorism Task Force in conjunction with North Carolina’s fusion center, ISAAC, that we are able to ensure public safety from these terrorist threats,’ said North Carolina State State Bureau of Investigation Director Robin P. Pendergraft.”

[Post from Infoglide] Data Finds Data in Real-Time Entity Resolution

“Jeff Jonas of IBM recently quoted from a chapter called “Data Finds Data”  that he co-wrote for a book entitled Beautiful Data: The Stories Behind Elegant Data Solutions, and I was impressed by how well this passage describes the effective use of entity resolution software (e.g., IRE 2.2)…”

IT-Director.com: GRC is not enough

[Philip Howard]”If you think about these different forms of risk, they can mostly be managed within existing GRC frameworks: business risk, data and IT governance and compliance cover five of these seven types of risk. But they don’t cover fraud or cyber attacks or similar security issues.”

SunSentinel.com: Roofer ducked $400,000 in worker’s comp premiums

“Investigators with the state’s Division of Insurance Fraud said Robert McDonald, owner of Gulfstream Roofing Inc., funneled $3 million in payroll through several fake companies between 2002 and 2006, claiming the money was being paid to insured subcontractors instead of his own workers.”

BNET Healthcare: What Can US Learn From European Health IT Experience?

“The three countries also use universal patient identification numbers in health care. This is much easier to do in Europe than it is in the U.S., where the mistrust of government is so high that the issue of having a single patient identifier number is no longer even under discussion. There’s also the small matter of our low EHR adoption rate, which is less than 20 percent for physicians and lower for hospitals. By contrast, most physicians in the three European countries are using some kind of EHR.”

information management: Multidomain Master Data Management for Business Success

“All data that flows through an enterprise can be categorized into six different types: who, what, when, where, how and why. Master data is about who, what, when and where. ‘Who’ data is about the parties of interest that matter most to a business or organization including stakeholders, benefactors, customers, suppliers, owners, providers, partners, etc.”

[Post from Infoglide] Entity Resolution as Data Mining

“In my last post, I suggested that entity resolution in the broadest sense (“Big ER”) really encompasses three activities.  The first is locating and collecting entity references from unstructured sources (entity extraction), the second is resolving and merging references to the same entity (“Little ER”), and the third is analyzing associations among entities.  Not every ER process involves all three activities.”

BeyeNETWORK: Some Perspectives on Quality

[Bill Inmon] “There are then very legitimate circumstances where incorrect data is best left in the database or data warehouse. Stated differently, there is no circumstance where correcting data or not correcting data is the right thing to do. In order to determine which approach is proper, the context of the corrections has to be known. Only then can it be determined whether correcting errors is the proper thing to do.”

Homeland Security Watch: How To Improve Homeland Security: Give the ODNI Oversight Responsibility for Fusion Centers

“To me, fusion centers are a fine example of Darwinian logic in homeland security.  There was no comprehensive national plan to create fusion centers.  In original intent, Founding-Fathers-federalism fashion, states and cities decided they were not getting the intelligence they wanted.  Arizona, Georgia, Illinois, New York and a handful of other jurisdictions took responsibility for processing - or “fusing” - their own intelligence.”

ITBusinessEdge: Master Data Management and the CIO’s Strategic Plan

“If we look at MDM as a collection of techniques providing enterprise-wide data requirements analysis and subsequent implementation of best practices in data management, then the savvy IT manager might cherry-pick from the tools offered by vendors to provide the optimal solution that unifies the view of critical data concepts while satisfying the data quality requirements imposed by a horizontal information solution.”

I, Cringely: Medical Records R Us

“So medical records are an area where IT could make us healthier and, if done correctly, ought to save lots of money, too.  What we need is some form of centralized medical record keeping that preserves patient privacy yet, at the same time, keeps us from shopping all over town for bogus Oxycontin prescriptions.”

[Post from Infoglide] iPhones, Identity Resolution, and Cloud Computing

“A personal favorite saying for years has been “invention is the mother of necessity” (a twist on the original saying, of course). It aptly conveys what has driven the high tech industry for the last several decades. Principles like Moore’s Law and its equivalent for the internet have created unanticipated waves of computing and networking power. All that available power has released the combined creativity of tens of thousands of engineers and marketers who dreamed up ways of interacting and managing our lives and businesses that were inconceivable 30 years ago…”

Liliendahl on Data Quality: Match Destinations

“When matching party data – names and addresses – very often it is not just only about hitting similar records, but also about performing some form of transformation with the data before, during and after the hitting.”

Tech Law Notes: Health IT & Open Source

“Repeatedly, I hear the refrain that this stimulus money is going to go to systems that can be put to a “meaningful use,” and that is going to exclude rogue open source Health IT developers from being funded, squelching innovation in the market place.  I imagine that complying with the security regulations under HIPAA probably hinder innovation, too, but they increase the reliability of the system vendors that remain in the market place and reduce the risk to the data of patients that might be in their computer systems.”

CiOZone: Ask the CIO: What’s your data management strategy?

“Undoubtedly, the recession has interrupted—or scaled back—some MDM-related work. But as Aaron Zornes said during an interview just before the July 4th holiday, ‘It’s not as if projects like risk management or Anti-Money Laundering, or Know Your Customer can wait until the economy improves.’ Some work just has to go forward—rain, shine, or economic downturn.”

Insurance Journal: California Efforts To Reduce Prison Budget Would Hurt Fraud Fighting

“‘Taking the power out of the hands of the public prosecutor to charge someone with a felony crime will have a serious impact on public safety. Insurance fraud is a serious crime that demands serious consequences,’ the Coalition Against Insurance Fraud, National Insurance Crime Bureau, National Health Care Anti-Fraud Association and the International Association of Special Investigation Units said in a joint letter to Schwarzenegger.”

“I don’t have access to the full text of the article, but I truly believe that once the pain of getting EMRs running as data collection appliances is over (meaning we’ve got data collection clerks known as doctors and nurses in place, which is the ‘pain’ part), the benefit will be incredible.”

[Post from Infoglide] What’s the Data Quality Business Message?

“What’s it going to take to move the data quality space forward in the future? That’s the question recently addressed by Ted Friedman of Gartner as reported in an article in destinationCRM.com. He suggests that the real answer may be messaging.”

CiOZone: Master Data Management Ready For Prime Time

“As with many application areas, Microsoft’s sweeping move into MDM signals a mainstreaming of the field, according to Aaron Zornes, founder and chief research officer of the The MDM Institute, Burlingame, Calif. ‘As a practice, MDM has been going on in some industries since 1980s, but it’s only been formalized with a growing, purpose-built vendor base in recent years,’ he says. ‘In the time since the institute was founded in 2004, the industry has matured considerably.’”

Life as a Healthcare CIO: International EHR Adoption

“The most widely implemented are England, Denmark, Netherlands, and certain regions of Spain which are close to 100%. Sweden, Norway are at 80% and behind and Germany/France are at 50%. The US is somewhere between 2 and 20%, depending on how you classify a comprehensive EHR.”

What’s the Data Quality Business Message?

What’s it going to take to move the data quality space forward in the future? That’s the question recently addressed by Ted Friedman of Gartner as reported in an article in destinationCRM.com. He suggests that the real answer may be messaging.

“Vendors have done a reasonably poor job in that they could get better at articulating the true business value [of data quality solutions],” he says. The Gartner analyst notes that vendors tend to talk about functionality in terms of technological advances, rather than conveying how that technology actually supports the business infrastructure. Friedman also notes that, in general, vendors could get better at articulating how tools support initiatives such as information governance and regulatory compliance — two notable industry trends.

Ted is right that to call out vendors to improve our messaging. At Identity Resolution Daily, we get down into technical details fairly often. For example, our bloggers have talked about data matching, its relationship to identity resolution, critical requirements for identity resolution, and we’ve had a series on data quality. Professor John Talburt of UALR’s Center for Advanced Research in Entity Resolution and Information Quality (ERIQ) is a regular contributor who talks about technical definitions and issues surrounding these topic areas.

That’s not to say that business issues around entity resolution and information quality have been ignored. Real world problems like lottery retailer fraud have been a frequent topic, as has organized retail crime. Another business problem we’ve talked about is employers trying to cheat workers compensation laws, and we’ve actually discussed regulatory compliance (OK, so we did get a bit technical on that one).

A huge issue related to information governance is preserving the rights of individual privacy. Because of our involvement in TSA’s Secure Flight program, we’ve written about this issue repeatedly since Identity Resolution was created. A recent post captures the essence of the issue.

So at best, I’d have to say we get a C+ or a B- on our messaging. With our upcoming release of IRE 2.2, we’ll make every effort to respond to Ted’s constructive criticism of the data quality space.

[Post from Infoglide] Entity Extraction

“In my last post I discussed my definitions for entity resolution, entity identification, entity disambiguation, and anonymous entity resolution.  (And I reiterate that these are just my definitions and are not binding on anyone except possibly my students.) Let’s go back to the overarching term entity resolution (ER).  In its broadest sense, I see ER as encompassing three major activities…”
