Hardly a day goes by without some new revelation of a U.S. IT mess that seems like an endless round of the old radio show joke contest “Can You Top This” except, increasingly, the joke is on us. From nuclear weapons updated with floppy disks to needless medical deaths, many of these IT snafus are caused by preventable interoperability communication errors, as has been the case for decades.
According to a report released to Congress, the Government Accountability Office (GAO) has found the U.S. government spent 75 percent of last year’s technology budget to maintain aging computers where floppy disks are still used, including one system for U.S. nuclear forces that is more than 50 years old. In a previous GAO report, the news was equally alarming as it impacts the healthcare of millions of American’s and could be the smoking gun a study from the British Medical Journal cites regarding medical errors as the third leading cause of death in the U.S.
The GAO interoperability report, requested by Congressional leaders, reported on the status of efforts to develop infrastructure that could lead to nationwide interoperability of health information. The report described a variety of efforts being undertaken to facilitate interoperability, but most of the efforts remain “works in progress”. Moreover, in its report, the GAO identified five barriers to interoperability.
CMS Pushing For ‘Plug and Play’ Interoperability Tools That Already Exist
Meanwhile, in a meeting with the Massachusetts Medical Society, Andy Slavitt, Acting Administrator of CMS acknowledges that, in his organization’s interoperability effort, “We are not sending a man to the moon. We are actually expecting (healthcare) technology to do the things that it already does for us every day.
“So there must be other reasons why technology and information aren’t flowing in ways that match patient care. Partly, I believe some of the reasons are actually due to bad business practices. But, I think some of the technology will improve through the better use of standards and compliance. And I think we’ll make significant progress through the implementation of API’s in the next version of EHRs which will spur innovation by allowing for plug and play capability. The private sector has to essentially change or evolve their business practices so that they don’t subvert this intent. If you are a customer of a piece of technology that doesn't do what you want, it's time to raise your voice.”
Slavitt claims CMS has “very few higher priorities” other than interoperability. It is also interesting that two different government entities point their fingers at interoperability, yet plug and play API solutions have been available through middleware integration for years — the same ones successfully used in the retail, banking, and hospitality industries.
As a sign of growing healthcare middleware popularity, Black Book Research named the top 10 middleware providers as Zoeticx, HealthMark, Arcadia Healthcare Solutions, Extension Healthcare, Solace Systems, Oracle, Catavolt, Microsoft, SAP, and Kidozen. There are also organizations such as the Center for Medical Interoperability which are strong advocates for middleware and EHR integration whose members include most of the largest hospital chains in the U.S., further proof of the level of interest in new technologies.
Medical Errors Third Leading Cause of Death in U.S.
The British Medical Journal recently reported medical error is the third leading cause of death in the U.S. after heart disease and cancer. As such, medical errors should be a top priority for research and resources, say authors Martin Makary, MD, MPH, professor of surgery, and research fellow Michael Daniel, from Johns Hopkins University School of Medicine. However, accurate, transparent information about errors is not captured on death certificates which are the documents the Center for Disease Control and Prevention (CDC) uses for ranking causes of death and setting health priorities. Death certificates depend on International Classification of Diseases (ICD) codes for cause of death, but causes such as human and EHR errors are not recorded on them.
According to the World Health Organization (WHO), 117 countries code their mortality statistics using the ICD system. The authors call for better reporting to help capture the scale of the problem and create strategies for reducing it. “Top-ranked causes of death as reported by the CDC form our country’s research funding and public health priorities,” says Makary in a press release. “Right now, cancer and heart disease get a ton of attention, but since medical errors don’t appear on the list, the problem doesn’t get the funding and attention it deserves. It boils down to people dying from the care that they receive rather than the disease for which they are seeking care.”
The Root Cause Of Many Patient Errors
Better coding and reporting are no-brainers and should be required to get to the bottom of the errors so they can be identified and resolved. However, in addition to not reporting the causes of death, there are other roadblocks leading to this frighteningly sad statistic such as lack of EHR interoperability. Unfortunately, the vast majority of medical devices, EHRs, and other healthcare IT components lack interoperability, meaning a built-in or integrated platform that can exchange information across vendors, settings, and device types.
Various systems and equipment are typically purchased from different manufacturers. Each comes with its own proprietary interface technology like the days before the client and server ever met. Moreover, hospitals often must invest in separate systems to pull together all these disparate pieces of technology to feed data from bedside devices to EHR systems, data warehouses, and other applications that aid in clinical decision making, research, and analytics. Many bedside devices, especially older ones, don’t even connect and require manual reading and data entry.
Healthcare providers are sometimes forced to mentally take notes on various pieces of information in order to draw conclusions. This is time consuming and leads to errors. This cognitive load, especially in high stress situations, increases the risk of error such as accessing information on the wrong patient, performing the wrong action, or placing the wrong order. Because information can be entered into various areas of the EMR, the possibility of duplicating or omitting information arises. Through the EMR, physicians can often be presented with a list of documentation located in different folders that can be many computer screens long leading to vital information being missed.
The nation’s largest health systems employ thousands of people dedicated to dealing with non-interoperability. The abundance of proprietary protocols and interfaces that restrict healthcare data exchange takes a huge toll on productivity. In addition to EHR’s physical inability, tactics such as data blocking and hospital IT contracts that prevent data sharing by EHR vendors are also used to prevent interoperability. Healthcare overall has experienced negative productivity in this area over the past decade.
The Devil Is In The Data Distribution
There are numerous areas in hospitals that are particularly vulnerable to deadly errors such as acute care settings requiring a complexity of care, time critical interventions, staffing, and the systems that are relied upon to tie these many IT resources together. However, due to the complexities and differences between health data systems, medical professionals are constantly presented with different user interfaces that must be consciously thought about to appropriately gather data as well as capture their decisions and treatment plans.
It is equally important to look at how the data stored in these disconnected, disparate systems is used. Much of the collection of patient, process, quality, and financial data in medicine looks like a large jigsaw puzzle with a number of pieces missing. Raw data and information is fragmented across numerous non-operable EHRs, both within a single hospital or clinic along with spanning geographic ranges. Connecting these pieces has focused primarily on the transfer of the information to those who request it, a manual and error prone process that is further compounded by lack of interoperability.
Dynamic Data Flow Extends Healthcare IT
Extending the power of health IT depends on understanding the idea of data flow which is critical to the management of entire populations of patients, either within a single clinic, hospital, health system, or entire community. We need dynamic data flow connected through smart interoperable middleware pipes so we can improve on the care delivered. The flow of data can be as important, or even more important, than the individual data points and connecting the patient, the data, and the interpretation depends on it.
Data flows contain signals and streams which allow automation and screening to take place. When we think at healthcare information technology from the perspective of data flow, we are not dependent on understanding every possible state or internal details, but can instead focus on the overall flow of the patient through the healthcare system. This allows for the design of complex analysis, automation, and understanding that is not possible with disconnected databases.
“To build a better system for solving medical errors, we need to understand the interdependent parts of the system to create a win for the patient in better care and less redundancy, a win for the healthcare professionals enhancing and optimizing their workflow and a win for the insurance companies who are already investing a great deal of resources into care management,” says Thanh Tran, CEO, Zoeticx, Inc.
Middleware Eliminates Need For HIEs
In addition to direct patient care, one of the benefits of middleware is it eliminates the need for Health Information Exchanges (HIEs) which are built atop middleware platforms and duplicate data, risking HIPAA violations in the process. They also require the synchronization and monitoring currency of the HIE data while creates barriers, including insufficient health data standards, variations in state privacy rules and difficulty in accurately matching the right records to the right patient.
In its annual interoperability survey of hospital and health system executives, physician administrators and payer organization IT leaders, Black Book Research found growing HIE user frustration over the lack of standardization and readiness of unprepared providers and payers. Of hospitals and hospital systems, 63 percent report they are in the active stages of replacing their current HIE system while nearly 94 percent of payers surveyed intend to totally abandon their involvement with public HIEs. Focused, private HIEs also mitigate the absence of a reliable Master Patient Index (MPI) and the continued lack of trust in the accuracy of current records exchange.
Now those using or considering an HIE have a new concern when the interoperability provider goes bankrupt as has Sandlot Solutions. The MCHC-Chicago Hospital Council (MCHC), which operates the MetroChicago Health Information Exchange (HIE) had to go to court to keep Sandlot from deleting its files until after the validation of their information was completed and delivered to MCHC. Additionally, several other Sandlot customers were dramatically affected by the same problem at significant cost to all those organizations.
