1 Myth, 2 Truths, 5 Hot Trends in Health IT

There is a myth out there that healthcare providers are unwilling to adopt new technology. It’s just not true. In the last few months, I have spoken to dozens of healthcare leaders at hospitals both small and large, and I am amazed at their willingness to understand and adopt technology.

Pretty much every hospital CEO, COO, CMIO or CIO I talk to believes two things:

With growing demand, rising costs and constrained supply, healthcare is facing a crisis unless providers figure out how to “do more with less.”

Technology is a key enabler. There is technology out there to help save more lives, deliver better care, reduce costs and achieve a healthier America. If a technology solution solves a real problem and has a clearly articulated return on investment (ROI), healthcare isn’t that different from any other industry, and the healthcare industry is willing to adopt that technology.

Given my conversations, here are the five biggest IT trends I see in healthcare:

1. Consumerization of the electronic health record (EHR). Love it or hate it, the EHR sits at the center of innovation. Since the passage of the HITECH Act in 2009—a $30 billion effort to transform healthcare delivery through the widespread use of EHRs—the “next generation” EHR is becoming a reality driven by three factors:

  • Providers feeling the pressure to find innovative ways to cut costs and bring more efficiency to healthcare delivery
  • The explosion of “machine-generated” healthcare data from mobile apps, wearables and sensors
  • The “operating terminal” shifting from a desktop to a smartphone/tablet, forcing providers to reimagine how patient care data is produced and consumed

The “next generation” EHR will be built around physicians’ workflows and will make it easier for them to produce and consume data. It will, of course, need to have proper controls in place to make sure data can only be accessed by the right people to ensure privacy and safety. I expect more organizations will adopt the “app store” model Kaiser pioneered so that developers can innovate on their open platform.

2. Interoperability— Lack of system interoperability has made it very hard for providers to adopt new technologies such as data mining, machine learning, image recognition, the Internet of Things and mobile. This is changing fast because:

  • HHS’s mandate for interoperability in all EHRs by 2024 means patient data can be shared across systems to enable better care at lower cost.
  • HITECH incentives and the mandate to move 50% of Medicare payments from fee-for-service to value-based alternatives by 2018 imply care coordination. Interoperability will become imperative.
  • Project Argonaut, an industry-wide effort to create a modern API and data/services sharing between the EHR and other systems using HL7 FHIR, has already made impressive progress.
  • More than 60% of the proposed Stage 3 meaningful use rules require interoperability, up from 33% in Stage 2.

3. Mobile— With more than 50% of patients using their smartphone to monitor health and more than 50% of physicians using (or wanting to use) their smartphone to monitor patient health, and with seamless data sharing on its way, the way care is delivered will truly change.

Telemedicine is showing significant gains in delivering primary care. We will continue to see more adoption of mobile-enabled services for ambulatory and specialty care in 2016 and beyond for three reasons:

  • Mobile provides “situational awareness” to all stakeholders so they can know what’s going on with a patient in an instant and can move the right resources quickly with the push of a button.
  • Mobile-enabled services radically reduce communication overhead, especially when you’re dealing with multiple situations at the same time with urgency and communication is key.
  • The services can significantly improve the patient experience and reduce operating costs. Studies have shown that remote monitoring and mobile post-discharge care can significantly reduce readmissions and unnecessary admissions.

The key hurdle here is regulatory compliance. For example, auto-dialing 9-1-1 if a phone detects a heart attack can be dangerous if not properly done. As with the EHR, mobile services have to be designed around physician workflows and must comply with regulations.

4. Big data— Healthcare has been slower than verticals such as retail to adopt big data technologies, mainly because the ROI has not been very clear to date. With more wins on both the clinical and operational sides, that’s clearly changing. Of all the technology capabilities, big data can have the greatest near-term impact on the clinical and operational sides for providers, and it will be one of the biggest trends in 2016 and beyond. Successful companies providing big data solutions will do three things right:

  • Clean up data as needed: There’s lots of data, but it’s not easy to access it, and isn’t not quite primed “or clean” for analysis. There’s only so much you can see, and you spend a lot of time cleansing before you can do any meaningful analysis.
  • Meaningful results: It’s not always hard to build predictive analytic models, but they have to translate to results that enable evidence-based decision-making.
  • Deliver ROI: There are a lot of products out there that produce 1% to 2% gains; that doesn’t necessarily justify the investment.

5. Internet of Things— While hospitals have been a bit slow in adopting IoT, three key trends will shape faster adoption:

  • Innovation in hardware components (smaller, faster CPUs at lower cost) will create cheaper, more advanced medical devices, such as a WiFi-enabled blood pressure monitor connected to the EHR for smoother patient care coordination.
  • General-purpose sensors are maturing and becoming more reliable for enterprise use.
  • Devices are becoming smart, but making them all work together is painful. It’s good to have bed sensors that talk to the nursing station, and they will become part of a top level “platform” within the hospital. More sensors also mean more data, and providers will create a “back-end platform” to collect, process and route it to the right place at the right time to can create “holistic” value propositions.

With increased regulatory and financial support, we’re on our way to making healthcare what it should be: smarter, cheaper and more effective. Providers want to do whatever it takes to cut costs and improve patient access and experience, so there are no real barriers.

Innovate and prosper!

How to Start Managing Cyber Risk

Hardly a day goes by without a news flash about another cyber breach. Since security breaches have become a daily occurrence, I sat down with Jeremy Henley at ID Experts to discuss the most common ways that companies are being breached and how companies can start to assess their cyber risk profile.

Question: Jeremy, what are the most common ways that you are seeing small to mid-size companies being breached?

Answer: One of the common ways that companies are being breached by hackers is that the hackers exploit vulnerabilities in the company’s security network. This includes the company’s failure to update software or upgrade their systems, as well as the failure to have the appropriate checks and balances in place. Small to mid-sized businesses are particularly vulnerable as they often don’t have the IT staff or budget to continually upgrade and update their systems as their organizations change and grow.

The second most common way companies are breached is through simple employee negligence. This would include a company’s failure to train and educate their employees on basic cyber security. For example, the failure to educate employees on the risks of downloading private data onto a portable device that is not encrypted as well as the failure to educate employees as to how to identify scams that ask them to open suspect emails or attachments. Companies need to educate their employees about the dangers of connecting to unsecured Wi-Fi connections at the airport or Starbucks when they are doing work that includes logging in to sensitive company systems. If someone is spoofing the airport Wi-Fi, you are essentially sharing everything you are doing online with that attacker.

Question: Once clients realize the security risks they face in today’s world, clients often ask where they should start with respect to updating their network security. Do you have any guidance for them?

Answer: I advise our clients to start by asking themselves three questions: 1) What data are we collecting? This is important as it will help them determine what regulations they may need to comply with (HIPAA /HITECH, PCI and 47 state breach notification laws, etc.), 2) How are they managing the data that they have? This includes examining what technology the company is using, if it is creating multiple layers to its security with firewalls and antivirus and if it is creating policies and procedures and training employees as to security safeguards and 3) I would ask the company to examine who they are sharing the data with. Specifically, which vendors or clients have access to its systems, and ask those vendors what security and privacy policies they have in place (if any)? You might consider requiring your vendors to provide proof of a security audit or insurance in the event they are the cause of a breach of info that you were trusted with.

Question: What role does cyber insurance play with your clients?

Answer: Cyber insurance has been invaluable to many of our clients, as most cyber policies include pre-breach education tools and employee training information as well as sample security policies or an incident response plan. Some carriers also work with us to provide risk assessment and penetration testing so that weaknesses can be identified and corrected prior to a breach incident. In my experience, the most valuable part that insurance plays is that the insured is able to fund an appropriate response in the wake of a breach. Clients that do not have cyber insurance usually do not have a budget set aside to deal with this unfortunate event, and after a breach do not have the funding to adequately fund the most appropriate response, therefore limiting their ability to respond to the significant reputational, financial and legal ramifications that such an incident can cause to their organization.

Medical Identity Theft And Fraud

Medical identity theft (MIDT) is a crime that has profound consequences for patients, insurance providers, and health care providers. The definition of medical identity theft is the fraudulent use of an individual’s personally identifiable information (PII), such as name, Social Security number, and/or medical insurance identity number to obtain medical goods or services, or to fraudulently bill for medical goods or services using an unlawfully obtained medical identity. Unfortunately, the definition of medical identity theft and the consequences that are associated with the crime are not common knowledge to the general public.

A recent study conducted by Harris Interactive on behalf of Nationwide Insurance found that only one in six (~15%) of insured adults say they are familiar or very familiar with the term “medical identity theft.” Of the 15% that professed familiarity with the term, only 38% could correctly define what a medical identity was (Medical ID Theft Study 4). Unfortunately, this lack of widespread understanding of medical identity theft by consumers is part of the problem and it is costing consumers, insurers, and healthcare providers alike.

According to the most recent Ponemon Institute Research Report, 1.85 million Americans were affected by medical identity theft in 2012. This is a dramatic increase from the 1.49 million affected by medical identity theft in 2011, amounting to an almost 25% increase in just one year (Third Annual Survey 1). This rate of growth has the potential to explode due to several reasons. First, The Affordable Care Act is estimated to reduce the number of uninsured by approximately 30 million (Insurance Coverage Provisions 13), drastically increasing the number of insurers and insured patients that are targets for medical identity theft. Second, HIPAA policies and new rules under HITECH are increasing the use of electronic health records (EHRs) which can be vulnerable to data hackers. And lastly, the data hackers themselves are more sophisticated and cognizant of ways to profit off of personal data than ever before. All these factors combined pose a very serious dilemma in controlling the rate of growth for medical identity theft. Ponemon estimates that the cost of medical identity theft to consumers in 2012 was approximately $41 billion (Third Annual Survey 1). This does not include the untold cost borne by healthcare and insurance providers. We cannot afford the cost of letting this crime grow.

In order to minimize the effects of medical identity theft we must better understand the nature of medical identity theft. The Identity Theft Resource Center (ITRC) knows it is important to assess how consumers’ identities are stolen, how they find out they have fallen victim to this crime, and how difficult it is to resolve once discovered. The Identity Theft Resource Center believes this information can be used to educate and make aware the general public as to what medical identity theft is and how they can minimize their risk or mitigate the cost once they become a victim.

Looking at how medical identity theft victims discover they have fallen victim to this crime is crucial in determining what can be done to discover medical identity theft sooner to avoid increased expenses and instances of fraud. The 2012 Ponemon report found that the most common way (39%) people discover they have become victims of identity theft is by receiving collection letters for delinquent bills. This is bad news as this means the costs for the fraudulent services worked their way through the providers’ billing systems and languished there until they were forwarded to collection departments or agencies. In the time it took for the bill to make it to the collection department or agency, the imposter could have committed many more instances of fraud in different locations. The second most common method of discovery (32%) was by noticing mistakes in their health records, tipping them off to the medical identity theft. This is also bad news as mistakes in health records can have catastrophic consequences which can be fatal.

Fortunately, the third most common method (26%) of discovering identity theft was by victims noticing suspicious postings to a statement or invoice, such as an Explanation of Benefits statement. This is very good news as this usually means the victim is discovering their medical identity theft as early as possible. The earlier the victim notices the crime, the more likely they may avoid damage to their credit score, stop future abuse of their medical identity, and reduce the amount of time and money spent to rectify the issue. This statistic is even more interesting when compared to the previous two years of the Ponemon study, where only 9% of participants indicated that they discovered their medical identity theft via suspicious statements of invoices. This is a promising example of how educating and making consumers aware of medical identity theft can make a big difference in helping reduce the incidence of medical identity theft and its costs as a whole.

Looking into the mitigation process victims are confronted with after they discover their medical identity theft reveals the costs and trouble they have to go through to clear their names. There are two distinct objectives when mitigating medical identity theft. First, the victim must deal with an individual incident such as a thief receiving medical care under the victim’s name and the associated fiscal impact the crime imposes. Second, the victim must now deal with the task of “curing” themselves of medical identity theft, insuring that their medical identity is not abused again in the future. This second objective is extremely difficult and contributes to the devastating nature of medical identity theft.

Regarding the first objective, the process for rectifying an individual incident of medical identity theft is complicated and drawn out. The victim must immediately contact the medical records and billing departments of the healthcare provider that provided the services to the imposter, request their medical records, and inform the provider that they are not responsible for the fraudulent bills. Upon learning that there may be fraudulent information in the victim’s medical record, the healthcare provider may deny the victim access to their medical record for fear of violating the Health Insurance Portability and Accountability Act (HIPAA). HIPAA protects the privacy of patients’ medical records making healthcare providers worry that they may be violating the imposter’s privacy rights by releasing the medical record to the victim. Oftentimes, the healthcare provider does not know for a fact that the fraudulent information in the medical record was a result of medical identity theft and cannot rule out that it may simply have been an accidental mixing of two patients’ records. Regardless of the situation, the healthcare provider is afraid of incurring liability under HIPAA for releasing confidential medical information even if it is under the victim’s name. The victim may have to appeal the decision in order to be able to view their records.

In one case, a medical identity theft victim was charged for bills related to the alleged amputation of one of her feet. Luckily, this was easily refutable as she would simply show the hospital billing department that she still has her two feet. Unfortunately, the imposter also had diabetes which prompted a physician, during a subsequent hospitalization, to ask the victim what medications she was taking to treat her diabetes. Note, the victim has never had the disease (Menn). This case demonstrates how frustrating correcting medical records can be and reminds us how dangerous medical identity theft is to the victim.

It is also recommended that victims file a police report and submit a copy of the report to healthcare providers as it will usually help streamline the process. It is important for victims to note that medical identity theft, like any other form of identity theft, is a crime police are required to provide a police report for in most states. Once the incorrect information is identified, the victim must request that the healthcare provider either remove the information or at least flag it should the provider be reluctant to permanently remove it. After correcting the records at the location the imposter received medical services, the victim will then have to request an accounting of disclosures listing all the entities to which the healthcare provider sent the victim’s fraudulent records. The victim must repeat this procedure at each location that has their fraudulent medical record. All of this creates mountains of work for healthcare providers, insurers, and the victims themselves which increases costs in the medical industry for everyone involved.

The second and more difficult objective, “curing” oneself of medical identity theft, does not have a set solution. The problem stems from the decentralized structure of the medical data system. Every healthcare provider, pharmacy, and insurer has its own records and records system. In contrast, the financial industry has three major credit reporting agencies through which almost all financial credit information is processed. Therefore, when you have suffered financial identity theft, a great way to mitigate future instances of fraud is to place a credit freeze with all three credit reporting agencies so that identity thieves cannot abuse your credit again. There is no such central medical record agency for medical records. Thus, it is possible for a medical identity thief to commit fraud with the same medical identity over and over again in multiple locations around the country. The victim will have to go through the individual incident mitigation process every time and just hope that the identity thief will stop using their medical identity.

Since there is no way to get ahead of the thief and prevent the medical fraud from occurring, the best way to mitigate the costs and effects of medical identity theft is for the victim to be vigilant and confront each instance of fraud as soon as possible in order to reduce the amount of wasted time and costs. This repetitive cycle is exhausting and costly for the victim as well as healthcare providers and insurers. In all three years Ponemon has conducted this survey, the number of victims who said they had completely resolved their medical identity theft never exceeded 11% (Third Annual Survey 11). This is an ongoing problem that does not yet have a solution, but it is imperative for all stakeholders to be involved.

All of this information points us to the realization that medical identity theft is a costly and potentially dangerous crime that is incredibly difficult to resolve. To make matters worse, medical identity theft often goes undiscovered for long periods of time and only becomes more detrimental and difficult to resolve the longer it goes undetected.

The Identity Theft Resource Center proposes that one of the best methods of reducing medical identity theft and the costs associated with it is an educated and aware consumer population. To make this point, it is useful to separate out the causes of identity theft listed in the Ponemon report into two groups. The first group includes causes of identity theft that victims have no control over: healthcare provider used identification to conduct fraudulent billing (22%), malicious employee in the health provider’s office stole health information (7%), and the healthcare provider, insurer or other related organization had a data breach (6%). In total, 35% of the causes of identity theft cannot be affected by actions of the consumer. The second group consists of causes of identity theft that a consumer does have a degree of control over: family member took personal identification credentials without my knowledge (35%), mailed statement or invoice was intercepted by the criminal (6%), lost a wallet containing personal identification credentials (5%), and a phishing attack by criminal who obtained personal identification credentials (4%). Thus, the total of causes of medical identity theft that can be affected by actions of the consumer is 50%. It should be noted that 15% of the participants still did not know how they had their medical identity stolen.

Looking at the numbers above, it is clear that the consumers themselves can have the largest impact in reducing the number of medical identity theft cases and the severity of the cases that still occur. Not only do the consumers themselves have the best ability to reduce the risk of medical identity theft happening to them, they are the only people that can reduce the severity of the crime when it does happen. The Identity Theft Resource Center has long understood the ramifications of medical identity theft on the consumer population as well as the medical industry itself. We know that educating the consumer population can be cost-effective and powerful.

The Identity Theft Resource Center is a founding organization of the Medical Identity Fraud Alliance, the first public/private sector-coordinated effort with a focused agenda that unites all the stakeholders to jointly develop solutions and best practices for medical identity fraud. We encourage all industry stakeholders to join so that we can work together in galvanizing the consumer population into becoming the most effective weapon yet against medical identity theft.

How Consumers Can Minimize Their Risk Of Medical Identity Theft

  • Review Explanation of Benefit statements as soon as you receive them as they may detail medical services that you never received.
  • Review your credit reports multiple times a year to see if any fraudulent accounts have been opened in your name, or if any medical bills have been reported as unpaid.
  • Be aware of phishing emails. These emails are designed to look like they are official communications from either a healthcare provider or insurer and ask for personal information such as a Social Security number, insurance policy number, or other information used to commit medical fraud in your name.
  • Do not open attachments in emails from people you are not familiar with as it may have a virus or program to steal information from your computer.
  • Use a Virtual Private Network when using the Internet outside of your home as this will encrypt your signal from your mobile device or laptop.
  • Do not carry your Medicare card, Social Security card, or certain military identification as these have your Social Security number on them. Should you lose your wallet or purse or have it stolen, this information would be extremely valuable to a medical identity thief.
  • Shred or safeguard any documents with personally identifiable information by either locking them in a safe hidden in the home or by storing them on an encrypted thumb drive and deleting them off your computer. Sensitive documents with PII include:
    • Tax preparation papers
    • Explanation of Benefits statements
    • Medical Bills or Records
    • Bank Statements
    • Passport
    • Medicare, Social Security, or military identification card

Restated HIPAA Regulations Require Health Plans To Tighten Privacy Policies And Practices

Health plans, their insurers, employer and other sponsors, and business associates have work to do. Health care providers, health plans, health care clearinghouses and their business associates will need to review and update their policies and practices for handling and disclosing personally identifiable health care information (“PHI”) in response to the omnibus restatement of the Department of Health & Human Services (“HHS”) Office of Civil Rights (“OCR”) of its regulations (the ” 2013 Regulations”) implementing the Privacy and Security Rules under the Health Insurance Portability and Accountability Act of 1996 (HIPAA). The Rulemaking announced January 17, 2013 may be viewed here.

Since 2003, HIPAA generally has required that health care providers, health plans, health care clearinghouses and their business associates (“Covered Entities”) restrict and safeguard individually identifiable health care information (“PHI”) of individuals and afford other protections to individuals that are the subject of that information. The 2013 Regulations published today complete the implementation of changes to HIPAA that Congress enacted when it passed the Health Information Technology for Economic and Clinical Health (HITECH) Act in 2009 as well as make other changes to the prior regulations that the Office of Civil Rights found desirable based on its experience administering and enforcing the law over the past decade.

Since passage of the HITECH Act, Office of Civil Rights officials have warned Covered Entities to expect an omnibus restatement of its original regulations. While the Office of Civil Rights had issued certain regulations implementing some of the HITECH Act changes, it waited to publish certain regulations necessary to implement other HITECH Act changes until it could complete a more comprehensive restatement of its previously published HIPAA regulations to reflect both the HITECH Act amendments and other refinements to its HIPAA Rules. The 2013 Regulations published today fulfill that promise by restating the Office of Civil Rights' HIPAA Regulations to reflect the HITECH Act Amendments and other changes and clarifications to OCR's interpretation and enforcement of HIPAA.

Highlights Of Changes
Among other things, the 2013 Regulations:

  • revise the Office of Civil Rights' HIPAA regulations to reflect the HITECH Act's amendment of HIPAA to add the contractors and subcontractors of health plans, health care providers and health care clearinghouses that qualify as business associates to the parties directly responsible for complying with and subject to HIPAA's civil and criminal penalties for violating HIPAA's Privacy, Security, and Breach Notification rules;
  • update previous interim regulations implementing HITECH Act breach notification rules that require Covered Entities including business associates to give specific notifications to individuals whose personally identifiable health care information is breached, the Department of Health & Human Services and in some cases, the media when a breach of unsecured information happens;
  • update interim enforcement guidance the Office of Civil Rights previously published to implement increased penalties and other changes to HIPAA's civil and criminal sanctions enacted by the HITECH Act
  • implement HITECH Act amendments to HIPAA that tighten the conditions under which Covered Entities are allowed to use or disclose personally identifiable health care information for marketing and fundraising purposes and prohibit Covered Entities from selling an individual's health information without getting the individual's authorization in the manner required by the 2013 Regulations;
  • update the Office of Civil Rights' rules about the individual rights that HIPAA requires that Covered Entities afford to individuals who are the subject of personally identifiable health care information used or possessed by a Covered Entity to reflect tightened requirements enacted by the HITECH Act that allow individuals to order their health care provider not to share information about their treatment with health plans when the individual pays cash for the care and to clarify that individuals can require Covered Entities to provide electronic personally identifiable health care information in electronic form;
  • revise the regulations to reflect amendments to HIPAA made as part of the Genetic Information Nondiscrimination Act of 2008 (GINA) which added genetic information to the definition of personally identifiable health care information protected under the HIPAA Privacy Rule and prohibits health plans from using or disclosing genetic information for underwriting purposes; and
  • clarifies and revises other provisions to reflect other interpretations and information guidance that the Office of Civil Rights has issued since HIPAA was passed and to make certain other changes that the Office of Civil Rights found appropriate based on its experience administering and enforcing the rules.

Covered Entities And Business Associates Must Act To Review And Update Policies And Practices
The restated rules in the 2013 Regulations make it imperative that Covered Entities review the revised rules carefully and updated their policies, practices, business associate agreements, training and documentation to comply with the updated requirements and other enforcement and liability risks. The Office of Civil Rights, even prior to the regulations, has aggressively investigated and enforced the HIPAA requirements.

The commitment of the Office of Civil Rights to enforcement most recently was demonstrated by its recent settlement with Hospice of North Idaho (HONI). On January 2, 2013, the Office of Civil Rights announced that the Hospice of North Idaho will pay the Office of Civil Rights $50,000 to settle potential HIPAA violations that occurred in connection with the theft of an unencrypted laptop computer containing electronic personally identifiable health care information. The Hospice of North Idaho settlement is the first settlement involving a breach of electronic personally identifiable health care information affecting fewer than 500 individuals.

While the Hospice of North Idaho settlement marks the first settlement on a small breach, this is not the first time the Office of Civil Rights has sought sanctions against a covered entity for data breaches involving the loss or theft of unencrypted data on a laptop, storage device or other computer device. Rather, the Office of Civil Rights continues to roll out a growing list of enforcement actions demonstrating that the potential risks of HIPAA violations are significant and growing. See also:

Coupled with statements by the Office of Civil Rights about its intolerance, the Hospice of North Idaho and other settlements provide a strong warning to covered entities of the need to carefully and appropriately manage their HIPAA encryption and other Privacy and Security responsibilities. Covered entities are urged to heed these warning by strengthening their HIPAA compliance and adopting other suitable safeguards to minimize HIPAA exposures.

In response to the 2013 Regulations and these expanding exposures, all Covered Entities should review critically and carefully the adequacy of their current HIPAA Privacy and Security compliance policies, monitoring, training, breach notification and other practices taking into consideration the Office of Civil Rights' investigation and enforcement actions, emerging litigation and other enforcement data, their own and reports of other security and privacy breaches and near misses, and other developments to decide if additional steps are necessary or advisable.
