My first exposure to Mobisante and their disruptive diagnostic ultrasound system was the mHealth Summit in November of 2010. At that time, the consumerization of medical devices had been gaining traction, mostly in the physician office market. Consumerization offers medical device manufacturers advantages in lower design costs, shorter time-to-market, lower product costs, increased usability and lower training costs.
I recently got Sailesh Chutani, co-founder and CEO of Mobisante, on the phone and we discussed their product strategy — a software based diagnostic ultrasound that runs on a variety of consumer electronics platforms.
Your product is clearly a diagnostic ultrasound medical device, but one can’t help but notice the rather unique design and choice of components. What were the factors driving the eventual design and appearance of your diagnostic ultrasound?Read More
If it were possible to be unaware of the general problem of cybersecurity, the recent Sony hack with its public disclosures of “private” e- conversations and then terroristic blackmail, following the earlier release of celebrity cloud photos, ought to have provided notice that what is electronically stored is likely to be available to those determined to have it. Moreover we know that cybersecurity can in principle also impact the function and availability of connected systems (Sony again) and/or the information they contain. We also need to be concerned about the malicious alteration of information or disruption of device performance. You may remember the hacked insulin pump story which is already a few years old, and the story that the wireless function of Vice President Cheney’s pacemaker was disabled to protect against hacking.
In this broad context it may be worth taking a look at the FDA’s now posted contents of the October 21-22, 2014 FDA workshop on “Collaborative Approaches for Medical Device and Healthcare Cybersecurity”. There is also a link there to the October 29 FDA Webinar on the Final Guidance on Premarket Submissions for Management of Cybersecurity in Medical Devices. (If that link doesn’t work, as it didn’t for me, try here.) I had not been not aware that October was National Cybersecurity Awareness Month under the auspices of the Department of Homeland Security (DHS).Read More
The Office of the Inspector General (OIG) of the U.S Department of Health and Human Services has released a report (pdf) outlining its 2015 work plan. Among a host of subjects is “Information Technology Security, Protected Health Information, and Data Accuracy” with the subsection “Controls over networked medical devices at hospitals”. The focus here is on the security of patient electronic health information which is to be protected under law. Other risks associated with device networking are not addressed.Read More
When I do presentations on the use of standards, I invariably have a slide which defines interoperability as “the ability of a system or a product to work with other systems or products without special effort on the part of the customer.” My second slide then defines syntactic and semantic interoperability.
Syntactic interoperability occurs when there are two or more systems capable of communicating and exchanging data and this is usually attainable with the use of physical standards, data standards, and messaging structures. Semantic interoperability is defined as the ability to automatically interpret the information exchanged meaningfully and accurately in order to produce useful results as defined by the end users of both systems.Read More
This summer, FDA proposed lifting regulations from certain currently regulated medical devices. This unprecedented policy shift targets devices known as Medical Device Data Systems (MDDS) and is intended to benefit the mobile app industry and companies like Google, Apple and others. The current regulatory burden for MDDS devices is Class I, 510(k) exempt. This means manufacturers have to follow a basic quality system (i.e., design controls) on par with ISO9001, and report instances of patient injury or death in addition to any product recalls to FDA.
The following is a guest blog post embodied in an abridged version of a comment submitted to FDA in response to their draft guidance.Read More
Clinical alarm safety can be hard to achieve, and once attained, a struggle to maintain. There are so many challenges:
- False/positive and non-actionable alarms;
- Optimizing default alarm limits across patient populations and for individual patients;
- Spread out nursing units with high patient-to-nurse ratios;
- Numerous alarm notification methods – audible signal amplification, monitor techs and alarm notification systems;
- And the constant threat of complacency and alarm fatigue.
The inaugural Clinical Alarm Safety Symposium, November 20-21, 2014, will delve into these issues and more to provide attendees with actionable information that can be later applied in your institution to ensure continued clinical alarm safety.
