Interventional informatics: from a bunker to the bedside Interventional informatics: from a bunker to the bedside

If the concept of interventional informatics were sketched as a cartoon, the drawing might be that of a doctor hunkered in a bunker under a hospital peering intently at a computer screen. One of the physician’s hands would rest on an oversized emergency alert button attached to a big, red, flashing strobe light while the other grasped a telephone receiver.

While this is a parody of the principle, it does support the definition of interventional informatics: the remote detection of high-risk patient conditions coupled with the appropriate human intervention.

More explicitly, interventional informatics involves monitoring the conditions of high-risk patients electronically using online records stored in the laboratory information system, electronic medical record, and other clinical information systems. The systems generate simple medical care alerts, which are directed to a remote “informatics bunker” instead of to medical staff on the patient care floors. A physician informaticist working in the bunker analyzes the alerts to identify the potential for harm to a patient or instances where evidence-based care can be improved. If necessary, the informaticist then works with the patient’s primary caregiver to develop an appropriate intervention.

“It’s augmenting computer knowledge, computer alerts, with off-the-floor human skill so the alerts that are generated can be triaged and evaluated remotely in the overall context of patient care. So by the time an alert reaches the clinical floor, it’s of high relevance,” explains Mark Pierce, MD. Dr. Pierce is an independent information technology consultant. He also practices internal medicine and pediatrics at Parkview Health, a not-for-profit, five-hospital system based in Fort Wayne, Ind.

Dr. Pierce and former Parkview administrator Mark Clare coined the term interventional informatics two years ago after a patient nearly died from hyperkalemia. At the time, Dr. Pierce was chief medical information officer at Parkview and Clare was vice president of operational excellence. Hospital administration challenged the two men to find a better way to monitor patients rather than relying on the traditional approach of placing most of the responsibility on caregivers on the patient floors. Caregivers may be susceptible to “alert fatigue,” meaning they may ignore computer-generated alerts, Dr. Pierce explains.

Studies show that between 49 and 96 percent of patient alerts are ignored or overridden because they are not deemed to be significant or because they appear as false positives too frequently, Dr. Pierce says. Incorporating a human component, a monitor who weeds out the false positives and intervenes when necessary to prevent harm or improve care, is a way to leverage the use of expensive clinical information systems, he adds.

“Even some of the folks who’ve implemented these $75 million systems are finding that their clinical outcomes aren’t that much better,” says Dr. Pierce. “So I think the time is rapidly approaching where [people] are going to say, ‘What other models are out there?’”

Parkview Health implemented interventional informatics on a trial basis in October 2006. Today, 83 percent of the alerts generated within the system using interventional informatics are accepted by medical staff, Dr. Pierce says. Of the 17 percent that are ignored, most of the time it’s because the reason for the alert has already been addressed, most often by physicians making their rounds. “So that means we are saving lives,” he says. “And, indeed, this October we’ll celebrate our second anniversary of no code blues from hyperkalemia.”

The system is financially worthwhile as well. Based on labor costs for patient monitoring, triaging, and intervening, Dr. Pierce says, the health system needs to prevent about half of an adverse event per month to break even. “Right now, we prevent about 3.2 [adverse events] per month,” he says.

Because Parkview Health has had success with interventional informatics, Dr. Pierce is spreading the word to other health systems. To that end, he has formed his own company, Interventional Informatics, LLC, and is giving presentations to health care information technology groups, such as the Healthcare Information and Management Systems Society. Dr. Pierce believes the concept will take hold in the next 18 months or so as the health care industry explores ways to improve clinical outcomes through avenues other than relying on expensive technology.

“I think this is an alternative model that focuses on value that can make a difference for patients,” he says. “The fact that the economics support it so well and it’s so cost effective, that’s just icing. The bottom line is: Here’s a model that works.”

Latest version of Opus lab system offers smartphone reporting Latest version of Opus lab system offers smartphone reporting

Opus Healthcare Solutions has introduced the latest version of its OpusLaboratorySuite lab information system. The new release includes remote re-porting, allowing physicians to view results on a smartphone or PDA via a cell phone network or a hospital’s wireless connection.

“The smartphone capability enables clinicians to quickly scroll through results and view data from a variety of screens or information sets instead of having to wait for a static document sent by fax or e-mail,” says Fred Beck, president of Opus.

OpusLaboratorySuite can be integrated with most major hospital information systems and is available as an installed product or application service provider offering. New features of the system include rules-based reporting, quality control prompts, call management, and enhanced integrated data ex-port to Microsoft Office.

The LIS contains modules for clinical microbiology, anatomic pathology, and management reporting with data mining. It is fully integrated with the OpusClinicalSuite series of Web-based products, which includes systems for clinical documentation, order management, computerized physician order entry, medication administration, and Web portals for remote physician access.

New release of SNOMED CT available New release of SNOMED CT available

The International Health Terminology Standards Development Organisation has released enhancements to SNOMED Clinical Terms, or SNOMED CT.

The latest SNOMED CT release includes:
  • improvements to the definitions of concepts in the specimen hierarchy. Fully defining concepts allows automated processes to place concepts in the hierarchy appropriately.
  • the addition of more than 2,000 new organisms to the organism hierarchy, as requested by public health authorities, including the Centers for Disease Control and Prevention.
  • implementation of standard naming conventions and consistent definitions for new imaging procedure concepts to allow for easier data retrieval.
  • The inclusion of dose forms, such as oral dosage, in many concept definitions in the pharmaceutical/biological products hierarchy. This enhancement improves a physician’s ability to identify specific drug products that have multiple dose forms and allows decision support systems to more readily differentiate between these forms for treatment, contraindications, and adverse effects.

SNOMED CT is a standardized clinical terminology that aids in capturing, exchanging, and aggregating health data. The latest release of the product includes more than 315,000 active concepts, 806,000 active descriptions, and 945,000 defining relationships.

SNOMED CT is owned by the Copenhagen, Denmark-based International Health Terminology Standards Development Organisation, or IHTSDO, and developed and maintained by SNOMED Terminology Solutions, a division of the College of American Pathologists.

Cognition Technologies launches abstracts database Cognition Technologies launches abstracts database

Cognition Technologies has introduced Semantic Medline, a database of 18 million article abstracts published by the National Library of Medicine.

Users of the free service, available at www.semanticmedline.com, can employ a natural, conversational sentence structure to find studies of highly complex health information within the Medline data set.

The Web site is powered by Cognition’s Semantic NLP natural language processing technology, which incorporates word and phrase knowledge to comprehend the meaning and nuances of the English language. Therefore, the search process is based on meaning rather than statistical word-pattern matching. Unique to Semantic Medline, says Scott Jarus, CEO of Cognition, “is an understanding of synonymy and the ability to understand meaning and context reasoning.”
