Review of Stage 2 Meaningful Use Test Procedure for Image Results …and other MU tests

I was just checking out the draft test procedure (PDF) for access of image results under Meaningful Use stage 2, §170.314 (a)(12).

This is the test that vendors seeking certification of their EHR products must complete and provide evidence of passing.

Often, EHR vendors get imaging wrong, but I think the authors of the test procedure got it mostly right. At least in terms of the requirements.

Essentially, the EHR must allow an authenticated and authorized user to be able to discover that exam images for a patient are available, and access the images (and associated “narrative”) in the EHR, or integrated systems, without requiring the user to re-authenticate, or search for the patient or exam.

Said another way, the system must have some form of Single Sign On (SSO) with the imaging system (or subsystem, if part of the EHR), and share the existing patient and exam context from the EHR to the imaging system.

A couple of comments…

  • I have seen SSO done well and poorly (read as: insecurely) between EHRs and imaging systems. When done poorly, it if often due to technical limitations in the EHR and/or imaging systems. Or, it is simply because the integration and/or IT staff lack the knowledge or effort to do it right (read as: securely). I have found that HIE and portal vendors and enterprise viewers are generally better equipped to properly handle SSO than EHR and PACS products (probably because they are generally based on newer technology and are often deployed in multi-facility environments that demand interoperability).
  • Integration from the EHR to a patient folder or specific exam has been around since PACS was first launched from an EHR well over a decade ago. What often gets lost is that users often want to compare exams side-by-side (e.g. pre-op and post-op). So, the imaging system may need to expand the context beyond a specific exam to allow this. As long as EHRs keep behaving like filing cabinets, the imaging viewer vendors will have to solve this.
  • The typical method of having an EHR be aware that an exam’s images are available for viewing is to push a modified HL7 ORU message, containing info about the exam, from the image manager to the EHR. The EHR then normally parses the info and uses it, along with a URL (or similar) string template, to create a context-sensitive link that can launch the viewer and present the desired exam. Some EHR can provide multiple exam identifiers, when the imaging viewer supports it, to show more than one exam in a single view. More modern methods for an EHR to discover the availability of an exam’s images is to use a REST-based query method, much like defined in DICOM‘s QIDO-RS (Query based on ID for DICOM Objects by RESTful Services) standard (in development).
  • An additional note on the URL to launch the viewer in context mentioned above: check out IHE’s work on the new integration profile Invoke Image Display (IID).

Some other test procedures that could be related to imaging…

  • Here (PDF) is the test procedure on authentication, access control, and authorization. And here is one on automatic log-off. I would have liked to see some requirements for SSO, like Kerberos or OAuth.
  • This test procedure on integrity requires a hash to be calculated and validated. This may (should) also be required for image exchange.
  • For the requirement for emergency access, if the imaging system does not allow the EHR to securely manage this (this can be done, by the way), the imaging system may have to also provide an emergency access override function (which means that the unique identity of the user had better have been passed securely to the imaging system, or it will have no idea to whom it is granting access).

Blog – Hospital versus clinic EMRs: what’s the difference?

Technology is easy these days—it really is. Knowing how to use it to solve a problem is harder. And truly understanding the problem is often the difference between success and failure.

I have always felt that one needs to understand the motivations, habits, and even fears of the user, as well as the environment where the product will be used, before design can start.

In this commentary, the author compares the differences between the hospital and clinic environment, and the people working there. I found it insightful, well-written and I learned some new things—check it out.

Article – AMA: EHRs create ‘appalling Catch-22’

I enjoyed this article.

Often, policymakers and executives debate the merits of an initiative. What is often lost in the shuffle are the important lessons and optimizations that make the program a success.

In the article, a number of folks discuss the implications of an EMR after implementation, including the possibility of fraud, or the incorrect perception that it has occurred.

My thoughts…

  • Fraud is easier to detect the more the information is electronic and coded. In fact, any pattern is easier to detect if extensive, well-structured data is available. Algorithms that detect possible fraud patterns will emerge, just as they did for credit card transactions. I recall a investigative news show on Medicare fraud where the agent stated that the move to electronic transactions and ‘smarter and smarter’ alogrithms have made their job easier. False positives will be a problem for a while until they get it right.
  • Coding of records is about to become a huge push. Beyond regulations for coding of data, there are several initiatives to provide codes for orderable procedures, lab/clinical observations, medical terms, diseases, medical/surgical/diagnostic services, and even imaging workflow concepts. Other groups are working to provide practical guidance on how to best use these codes in different contexts. This article talks about the need for better and more coding.

And here is an article on a Web site where EMR users can rate their EMR. There are some interesting comments in the article.

Also, an Accenture survey finds a significant increase in the use of EMR and HIE technology by physicians.

Article – Can a smartphone do what your doctor does?

This article provides a summary of medical devices and apps that connect to your smartphone and collect physical examination information. The author is a doctor and provides a good explanation of the utility and necessity of the different tests.

The devices assessed by the article’s author include…

  • Blood Pressure Monitor by Withings and Blood Oxygen Monitor by iSp02
  • ECG Cellphone Case by AliveCor
  • iExaminer by Welch Allyn
  • SpiroSmart

From her assessment, it seems that the medical tricorder is slowly becoming a reality. I do agree that having a separate app to view the results from each device is a PITA, but this should not last long. With Bluetooth and WiFi connected devices wireless tethered to the smartphone, and new data formats and protocols popularized in HTML5, the shift to storing the collected information into the EMR or HIE will be soon.

Article – MRI Payment Cuts Having Dramatic Effect on Radiology Groups

Last month, I posted about reimbursement cuts to two popular MRI exams.

In this article, the impact of these changes to Radiology groups are explained fairly clearly. Worth a read if you make your living (directly or indirectly) from Radiology services reimbursement.

Thoughts on Telemedicine

In reading some of the comments from Lynn Britton, president and CEO of Chesterfield, Mo.-based Mercy at the ATA’s (American Telemedicine Association) 18th Annual International Meeting & Trade Show from this article, it reminded me of some comments I made in this post.

The quote from the article that stood out to me…

“If we had thought about the classic return on investment around the infrastructure we built, we would have had second thoughts about it,” he said. “But the return is there, because that infrastructure is robust and sound, because we can provide those services in every one of those communities you saw on that map.”

Message to providers: expand your network, expand your services, lower your costs …or fall behind.

Here is another article titled “3 things that will help telemedicine go mainstream and win over pessimists” based on ideas shared at the ATA’s annual meeting.

And here is an article titled “3 ways telemedicine is helping Wyoming”, which describes how telemedicine is providing valuable services to the people of the 2nd least densely populated state (only Alaska has fewer people per square mile).

Article – CHIME seeks Stage 2 delay, defends MU

So, the U.S. government—CMS/ONC and some Senators—and CHIME (College of Healthcare Information Management Executives) are “discussing” the merits and best timing of HITECH and Meaningful Use.

This article provides a good summary of the questions and recommendations posed.

Some key points from the article and my thoughts…

  • The Senators are fairly looking for evidence of results from the significant investment of taxpayer dollars. The reality is that this change is large and multifaceted. It will take time to reap the benefits once operations are normalized and productivity is enhanced.
  • CHIME believe that there are merits to the government’s programs, but wants to slow the pace of change. I know from personal conversations with smart, effective folks working for respected providers that they are reeling from the number of implementation projects driven by ACO, MU and other initiatives that they have going right now. The troops may indeed need a short break and to reflect on lessons learned from the initial change.
  • “CHIME also urged Congress to request an update from ONC regarding what technologies, architectures and strategies exist to mitigate patient matching errors” …it is interesting that CHIME is looking for this, as MPI (Master Patient Index)—also known as PIX (Patient Identifier Cross-Referencing) in the IHE Technical Framework—has been around for years and used in many projects to enable sharing of patient records across patient ID domains

Article – Outpatient services will dominate 2013, survey says

Healthcare providers are shifting their focus from providing inpatient services to providing outpatient services—and their investment priorities reflect this, according to a survey.

Some key stats from this article

  • 69% of survey respondents projected an increase in outpatient volume for 2013, while only 35% predicted an increase in inpatient volume
  • 43% of respondents plan to make health IT their biggest capital investment in 2013, up from 21% two years ago
  • 22% of respondents were part of an Accountable Care Organization, and 55% planned to be part of one by 2014

Article – Radiology Staffing: How to Do More with Less

A lot of people are talking about using analytics to make operational improvements (read as: lowering costs while improving quality of service), but this article describes some specific ways to do this within a Radiology practice.

Examples (from the article)…

  • Use actual procedure data to determine the specialty needed, as well as the number of staff needed in each facility/location. It also helps determine if full-time or part-time staff are needed.
  • Adapt the daily shift schedule based on hourly exam volume peaks.

The article also explains how technology is used to improve efficiency…

  • Cloud based image sharing, integrated with PACS, to distribute reading of exams among distributed Radiologists.
  • Shared worklist across facilities

Blog – FHIR Version 1.0

Check out this blog discussing FHIR. While the initial post seeks to simplify the intent of FHIR to a practical application (essentially a summary document), if you read the author’s own comments on their post, they are already starting to realize the real value of FHIR.

FHIR creates the platform, and the summary document is an application of the platform.
