The Future of Wearable Technology: Why Sensors Are the Better Option

As technology advances, wearables have become increasingly popular in the health and fitness industry.

However, sensors may prove to be the better option when it comes to tracking and monitoring various aspects of our health. Let's start a conversation about the benefits of using sensors over wearables and why it is the future of technology.

Violent video games, Explicit lyrics and the Usability of Health IT

Back in the 1980s Tipper Gore. Susan Baker, and several others created the Parents Music Resource Center (PMRC) with the intent of increasing parental control over the access of children to music deemed to have violent, drug-related or sexual themes. They used their influence as “Washington Wifes” to push for regulation of the music industry. By 1985, 19 record companies agreed to put "Parental Guidance: Explicit Lyrics" labels on albums to warn consumers of explicit lyrical content.


Many EHRs really do suck, as ZDoggMD described in his very popular parody video 'EHR state of Mind'. But without some nudge towards an improved user experience many of the "less than optimal" EHRs will only get worse as they grow and Engineering-centric developers add more and more features on top of a poorly designed information architecture.

Vehicles are not allowed to be sold in the USA unless they have meet strict safety standards, why isn't this the same for EHRs?

FDA Issues Draft Guidance for Medical Device Interoperability

The FDA issued new draft guidance aimed at improving interoperability among connected medical devices, Clinical Innovation & Technology reports.

Details of Draft Guidance

The draft guidance provides connected medical device manufacturers with:

  • Design considerations for developing interoperable medical devices; and
  • Information to include in pre-market submissions and device labeling (Walsh, Clinical Innovation & Technology, 1/26).

FDA noted that "errors stemming from inadequate interoperability can occur, such as the transmission of weight in kilograms when the receiving medical device assumes the measurement is in pounds, and that can lead to patient harm and even death" (Conn, Modern Healthcare, 1/26).

FDA called on device manufacturers to:

  • Conduct appropriate performance testing and risk management activities;
  • Design systems with interoperability as an objective;
  • "Exer[t] command and control" over other devices;
  • Publicly share the functional, performance and interface characteristics; and
  • Standardize architecture and communication protocols.

The agency also said manufacturers should consider whether their devices can handle data:

  • That have been "corrupted"; or
  • From "outside ... appropriate parameters." 

FDA in its draft guidance said, "Increased use of interoperable medical devices has the potential to foster rapid innovation at lower cost," adding, "However, appropriate safety considerations, including system-level safety considerations that are not taken into account in the device design can result in unforeseen safety and effectiveness issues for the device or for the system."


Joseph Smith, chief medical and science officer at the West Health Institute, praised the draft guidance's expansion of the definition of interoperability to include actual use of shared data. He said, "Only through automatic use of information are we going to take full advantage of the many separate gifted gadgets to create an integrated and automated, connected and coordinated whole."

Meanwhile, Bradley Merrill Thompson, an attorney with Epstein Becker & Green, said, "All FDA has the legal authority to do is convey through guidance what the agency expects in the way of appropriate labeling, design, validation and so forth for products that the manufacturer intends to be interoperable with some other devices." He added, "FDA can and does play an important role in defining the minimum required labeling, design, validation and so forth to support a product intended to be interoperable" (Bowman, FierceHealthIT, 1/26).

Cybersecurity Advocacy Group Calls for Universal Principles

In related news, a cybersecurity advocacy group has published an open letter to the health care industry to adopt five principles for creating, using and maintaining medical devices, Computerworld reports.

The group, called I Am the Cavalry, urged medical device manufacturers and other health care stakeholders to:

  • Capture and analyze evidence of potential failures;
  • Collaborate with security researchers;
  • Implement security by design;
  • Provide easy-to-install security updates; and
  • Safeguard critical elements for operation in adverse conditions.

To achieve the goals proposed, the group, among other things, recommended:

  • Avoiding known flaws;
  • Avoiding unsecure remote access;
  • Implementing proven processes for receiving vulnerability reports; and
  • Making the medical device update process more secure (Constantin, Computerworld, 1/19).
