I Wonder What Is Going On With the Terminology Function At NEHTA?


First we hadthis appear.
Subject: NEHTA - National ClinicalTerminology & Information Service - AMT monthly releases between August andDecember 2011
Date: Thu, 25 Aug 2011 09:30:17 +1000
From: "NCTIS ServiceDesk"<nctis.servicedesk@nehta.gov.au>
NEHTA - National Clinical Terminology &Information Service - AMT monthly releases between August and December 2011
Since2007 the NCTIS has been issuing monthly national releases of the AustralianMedicines Terminology (AMT) incorporating new items registered with theTGA.
Whilethe AMT has been implemented in clinical systems in Australia, NCTIS has beenconsulting with software vendors and the terminology community about how we canincrease uptake. As a result of this consultation and our recent AMT licenseholder’s survey we have identified a range of materials that would assistpeople implementing AMT. These materials will be defined in an AMTImplementation Plan that will be published on NEHTA’s website shortly. The AMTImplementation Plan will set out pathways to implement AMT, includingintegration guidance and include timeframes for deliverables such as AMT v3.
Inorder to respond to the market and deliver material requested by implementersover the coming months, NCTIS is pausing AMT monthly releases until December2011. This decision has come following consultation with healthcareorganisations and vendors that have already completed large scale AMTimplementations, and have confirmed their operational use of AMT in clinicalsettings will not be impacted by this action.
We lookforward to continuing our work with you to use AMT throughout the healthcaresector to support consistent terminology in medications management. Should youhave any questions, comments or feedback, please direct these to terminologies@nehta.gov.au.

Then a dayor so ago we had a follow-up.
Subject: Request for feedback - SNOMED CT-AU
Date:       Thu, 1 Sep 2011 13:00:03 +1000
From:      NCTIS ServiceDesk
To:            undisclosed-recipients:;
Requestfor feedback on your dependency on SNOMED CT-AU release date
NCTIS released the first nationalrelease of SNOMED CT-AU in December 2009 and has been following a six monthlyrelease cycle since then. To support the national Personally ControlledElectronic Health Record, NEHTA is undertaking additional development of detailedclinical models and associated SNOMED CT-AU reference sets.  At the sametime, we are also investing resources in the development of AMTv3 which willmore closely align with SNOMED CT-AU, and to develop other implementationresources to help vendors and implementers use AMT.
To allocate NEHTA resources tothis work, the NCTIS is considering delaying the November 2011 release. We arealso investigating aligning Terminology releases with other Specificationreleases, such as Specialist letters, to provide a more integrated release toimplementers. While we need to consult with users of NEHTA’s specifications andterminology to determine the viability of this, we can confirm that the nextSNOMED CT-AU will be no later than May 2012.
In order to evaluate thesignificance this may have we are now writing to license holders to determinewhether a delay would have an impact on any clinical application using SNOMEDCT-AU. We have already written to all license holders who downloaded any of ourlast three releases, and have not had received feedback that any clinicalapplication would be impacted, and the results of our recent user surveyindicate this is not the case more broadly with other license holders. However,we would like to confirm this directly with you.   
If you have implemented SNOMEDCT-AU in a clinical setting and would be impacted by a delay in the Novemberrelease, please advise us by COB Tuesday 6th September at terminologies@nehta.gov.au or 07 3023 8400.
We look forward to continuing ourwork with you to use SNOMED CT-AU throughout the healthcare sector to supportconsistent terminology in clinical management.

What NEHTAseems to be saying here is that we can’t actually walk and chew gum and so doyou mind if we stop chewing so we don’t fall over.
More amazinglyit seems after working for at least six years on the Australian MedicinesTerminology only now have they discovered a need to actually have animplementation plan!
Surely anorganisation that is being funded as well as NEHTA is can continue its ‘businessas usual’ functions while undertaking some planning and improved servicedelivery changes?
It isinteresting that Sept 1, 2011 the Health Minister announced some updates to thePharmaceutical Benefits Scheme Coverage:
See here:

Erbitux, Gilenya and Other Medicines Listed on thePBS

More than 400,000Australians will benefit from new subsidised medicines from 1 September 2011,including patients suffering multiple sclerosis, cystic fibrosis and variousforms of cancer.
.....
In all,twenty-one (21) new listings on the PBS come into effect from 1 September. Moredetail on these is available on the PBS website at www.pbs.gov.au.
-----
So alreadythe current AMT is way out of date!
Also rememberthat SNOMED-CT is also meant to be the terminology underpinning the PCEHR - butit is now on hold until the end of the year apparently. I suspect that willneed an implementation plan as well!
Bottomline is that under NEHTA’s management we see major initiatives such as clinicalterminology simply floundering and not being used as might have been hoped.
(Of coursewe all know there are a few fundamental issues with SNOMED-CT - I wonder howthat fits into this ‘pause’? See here:
I wonderwhen the powers that be will notice all this is not exactly going as planned?
Soon Ihope!

State, Federal Health Data Exchange Efforts Heat Up

The need for robusthealth information exchange (HIE) continues to grow, and not just because it isa part of the meaningful use incentive program. Having infrastructure tosupport HIE will be a critical component to enable new payment and caredelivery models like accountable care organizations and medical homes.
Backgroundon HIE Efforts
There has been astrong national effort in developing the Nationwide Health Information Network(NwHIN), as well as a dramatic increase in local and regional efforts to createviable health information exchange organizations (HIOs). These efforts includethe Direct Project, which created asimple, secure, scalable, standards-based way for participants to sendauthenticated, encrypted health information directly to known, trustedrecipients over the Internet. The Direct Project -- which was sponsored by theOffice of the National Coordinator for Health IT -- has become an importanton-ramp to the health information superhighway.

Hacked Medical Device Sparks Congressional Inquiry

Legislators demandanswers after a security researcher remotely controlled his own insulin pumpusing a $20 radio frequency transmitter at Black Hat.
By Mathew J.Schwartz,  InformationWeek
August 23, 2011
Two members of Congresshave asked the Government Accountability Office (GAO) to review the FederalCommunications Commission's approach to medical devices with wirelesscapabilities to ensure that the devices are "safe, reliable, andsecure."
The letter to the GAO, fromReps. Anna G. Eshoo (D-Calif.) and Edward J. Markey (D-Mass.)--both members ofthe House communications and technology subcommittee--was sparked by a medical device hackingdemonstration earlier this month at the Black Hatconference in Las Vegas.
While most BlackHat presentations typically detail exploits launchedagainst others or more benign forms of hardware hacking, securityresearcher Jerome Radcliffe actually hacked--live and onstage--his own insulinpump, which he relies on to subcutaneously administer multiple doses of insulinper day. Radcliffe, 33, said he was diagnosed with diabetes at age 22.

Reaping the Benefits of Electronic Medical Records

Researchersuse natural language processing to flag postsurgical complications inphysicians' notes.
Despite billions of dollars in incentives to support theadoption of electronic medical records, evidence that these systems improve theefficiency or quality of care has been scarce. But a new study shows thatnatural-language processing—a branch of computer science that employslinguistics to analyze regular speech—may greatly increase the utility of theserecords in improving care.
Researchers usedthis approach to sift through physicians' notes, the richest and mostcomplicated aspect of electronic medical records, for postsurgicalcomplications such as pneumonia and sepsis. The method proved considerably moreaccurate than other automated systems. They say similar approaches could beused for a variety of applications, including predicting which patients are atrisk, and developing automated tools that help doctors choose treatments. 
"You canfinally see how clinical data can be used to measure patient safety moresystematically, and that we will really be able to use these things to managecare," says Ashish Jha, a physician atHarvard Medical School who wrote an editorial accompanying the paper. The paperand editorial were published this week in Journal of the AmericanMedical Association.

NaturalLanguage Processing Improves Complication Tracking

August 23, 2011 —Analysis of electronic medical records (EMRs) with natural language processingshows an improved ability to identify postoperative surgical complicationscompared with the standard method of relying on administrative data codes,according to a new study published in theAugust 24/31 issue of JAMA.
In efforts toimprove patient safety, hospital administrative data are typically screened forcodes that may reflect potential adverse events during hospitalization, and aquality surveillance tool developed by the Agency for Healthcare Research andQuality has refined that process to focus on a set of 20 patient safetyindicators used in screening the data.
However, the systemhas some drawbacks, including some uncertainty about the validity ofadministrative codes and the inability of discharge codes to distinguishwhether a disease existed before a patient's admission or was acquired duringhospitalization, according to Harvey J. Murff, MD, MPH, lead author of thestudy from Tennessee Valley Healthcare System, Veterans Affairs Medical Center,and Vanderbilt University, Nashville, TN, and colleagues.
The emergence ofEMRs, combined with the development of automated systems such as naturallanguage processing, however, allows for screening of more extensive medicaldata and documents and extraction of specific medical concepts, as opposed tosimply searching for potentially unreliable discharge codes.

How Radio Waves Remedy Patient Bottlenecks

Gienna Shaw, forHealthLeaders Media, August 23, 2011

RFID tags have fora while been used mainly for things—to keep track of the number of bandagesleft in the supply closet or to keep an expensive piece of equipment fromwalking out the door, for example. Increasingly, though, those badges areshowing up on the lapels of patients. And hospitals are using the data thoseRFID badges gather to improve patient flow, shorten length of stay, and more.
Wilmington,DE–based Christiana Care Health System pins patients with RFID tags to tracktheir movements throughout the continuum of care. The collected data is an"extremely powerful" tool for process improvement, says Linda Laskowski-Jones,vice president of emergency and trauma services for the two-hospital system.
The system tracksinterval-level data—measuring the time a patient spends in between eachactivity—from the time they see a doctor to the time the doctor orders labs oran x-ray, for example.

August 17, 2011
The University of IowaChildren's Hospital is getting ready to launch a Facebook page that willmonitor teenage and young adult kidney transplant patients in an effort to getthem to take their medications on time. The hospital will use prescriptioninformation from its electronic health record (EHR) system to populate the sitewith the list of medicines each patient is taking, and how many times dailythey should be taken.
The initiative,which is been developed by Dr. Patrick Brophy, director of the division ofpediatric nephrology, dialysis, and transplantation, along with the hospital'stechnology department, was borne out of Brophy's frustration that many of histeenage kidney transplant patients were not taking their medications aftersurgery.

Building Public Trust in Electronic Health InformationExchange

Given the valuethat individuals place on the privacy of their health information, it is notsurprising that there is a federal advisory committee charged with helping theOffice of the National Coordinator for Health IT protect the privacy andsecurity of health information exchanged through electronic health recordsunder the Medicare and Medicaid EHR Incentive Programs. This group -- asubcommittee of the Health IT Policy Committee -- is the aptly named privacyand security "Tiger Team."
Backgroundon the Privacy and Security Tiger Team
ONC first assembledthe Tiger Team in June 2010. The group includes15 members from the Health IT Policy Committee, theHealth IT Standards Committee and the National Committee on Vital and HealthStatistics.
As a matter ofscope, the Tiger Team develops privacy and security recommendations forelectronic HIE, in which health care providers must engage to demonstratemeaningful use of EHRs under the Medicare and Medicaid EHR Incentive Programs.Generally speaking, this includes electronic exchange for the purposes of treatment,care coordination, and quality and public health reporting.

Natural Language Processing - A Method To Better Exploit the Information Content in EHRs?

While there is nothing new under the sun it does seem there have been some progress in utilising Natural Language Processing (NLP) for clinical and research purposes.

Natural language processing better for spotting quality lapses after surgery: study

By Joseph Conn

Posted: August 24, 2011 - 11:45 am ET

Are computer programs that read text-based medical records ready for prime-time use in quality improvement? Maybe so, according to research published in the latest issue of the Journal of the American Medical Association.

Quality-improvement researchers concluded that computerized natural language processing of free-text portions of patient medical records was more effective in identifying quality lapses in post-operative surgical patients than a computerized review of discrete data elements in those records. Natural language processing, or NLP, is the use of computers to read and process information expressed in human language.

The researchers looked at the randomly selected records of 2,974 hospitalized surgical patients at six U.S. Veterans Affairs Department medical centers from 1999 to 2006 that were reviewed through the Veterans Affairs Surgical Quality Improvement Program.

A report on their findings, "Automated Identification of Postoperative Complications Within an Electronic Medical Record Using Natural Language Processing," appears in the Aug. 24/31 issue of JAMA.

In conducting the study, researchers obtained from the VA's VistA electronic health-record system narrative clinical notes, such as discharge summaries, progress notes, operative notes, microbiology reports, imaging reports and outpatient visit notes.

The quality-improvement program records had been assessed for 20 "patient safety indicators" developed by the Agency for Healthcare Research and Quality that rely on structured administrative data, such as ICD-9 codes, from hospital discharge records to identify possible adverse events.

Reaping the Benefits of Electronic Medical Records

Researchers use natural language processing to flag postsurgical complications in physicians' notes.

Despite billions of dollars in incentives to support the adoption of electronic medical records, evidence that these systems improve the efficiency or quality of care has been scarce. But a new study shows that natural-language processing—a branch of computer science that employs linguistics to analyze regular speech—may greatly increase the utility of these records in improving care.

The method proved considerably more accurate than other automated systems. They say similar approaches could be used for a variety of applications, including predicting which patients are at risk, and developing automated tools that help doctors choose treatments.

"You can finally see how clinical data can be used to measure patient safety more systematically, and that we will really be able to use these things to manage care," says Ashish Jha, a physician at Harvard Medical School who wrote an editorial accompanying the paper. The paper and editorial were published this week in Journal of the American Medical Association.

One of the most anticipated benefits of electronic medical records is computerized tracking of patients and institutions—to detect whether a particular patient is at risk for a specific complication, for example, or a specific department or hospital is performing more poorly than others.

Automated tracking is already in use in prescribing; for example, to detect when two medicines interact. Because prescription information is a highly structured part of the medical record, it has been fairly easy to analyze with software. However, harnessing the vast information available in less structured parts of the medical record, such as clinicians' notes—which contains free-form entries about the patient's history and status, including postsurgical complications—is much harder.

"If we can't access that information, we will have a hard time monitoring records to improve care," says Jha. "This paper is so powerful because it shows you can do this."

.....

Nuance, a leading maker of voice-recognition software, is already developing commercial systems that use natural-language processing to analyze medical information. The company is collaborating with the IBM team that developed Watson, the robot made famous by beating human contestants on the television game show Jeopardy, to apply the robot's natural-language processing tools to medicine.

The bottom line here is that we now have essentially proven technology which in the right circumstances can make a real difference to what we know about what is going on in the health system. Another tool seems to be becoming very much more useful.
