Orcha, app assessment and the future 14th July

Our next free webinar will be on Wednesday 14th July at 10am when Liz Ashall-Payne, CEO and Lloyd Humphreys, Managing Director, present on recent developments at Orcha, their new methodology for app assessment and how they see the company changing in the future, To find out more and to book, click here.

Medical device regulation, UKCA and CE certification

A recording of the BSI presentation earlier this month is on the website, together with a copy of the presentation, and the BSI’s most recent publication on the topic. All are accessible here.

Our next DHACA Day

As mentioned in the previous newsletter, the intention is to run our first DHACA Day on 15th September. It’ll likely be a half-day only – just he morning plus lunch. So far we have three speakers sorted – let me know if you particularly want someone invited to speak. Worth holding in your diary.

Important information

Chips’re orf!

The chip shortage seems to be a good reason for all sorts of things not happening, including slowing the advances of the cellular IoT industry. Berg Insight reports that a double whammy is still impacting the sector.

First, the pandemic affected demand in several major application areas in 2020. And second, extra pain is being inflicted by the global chip shortage, which is expected to curb growth in IoT device shipments this year. Over the longer term, Berg thinks a key accelerant will be so-called reduced capability (RedCap) devices poised for introduction following the upcoming 3GPP Release 17. These will be less expensive than the 5G devices being deployed today but offer higher data rates than LPWA technologies such as LTE-M and NB-IoT. It says modules supporting the specification will likely reach the market in 2023 on wearables, video surveillance and industrial monitoring devices. You can get more detail from this brochure.

Personal health technologies and infectious diseases

Continuing our theme on how technology is changing the role of doctors, Lancet Digital Health has a  Viewpoint article entitled “The hopes and hazards of using personal health technologies in the diagnosis and prognosis of infections”. There’s a good summary in there particularly of how personal health technologies can be used in diagnosing and caring for infectious diseases. However many of the points should be familiar to DHACA members, such as that parameters like blood pressure, pulse rate and body temperature vary between individuals so a good sensing methodology first establishes the base from which deviations might then be identified. Most medical research papers seem to include a requirement for more research and this is no exception, though it seems especially valid: “As new metrics are added to sensors, substantially greater research is needed to better understand wearable changes for different infections, asymptomatic infections, non-infectious insults, and tracking long-term consequences, such as with post-acute sequelae of SARS-CoV-2 infection.”

And whilst we’re on wearables, Dr Eiman Kanjo of Nottingham Trent University on LinkedIn claims to have developed a wrist-worn sensor that is significantly cheaper than any other, although at present the URL for her Sensor Lab is not resolving.

Digital tools for mental health management

Lancet Digital Health has a short Editorial on Digital tools for Mental Health in a Crisis. Apparently WHO found that, of 130 countries surveyed, 91 (70%) have adopted telemedicine or teletherapy for MHPSS; evidence suggests that these remote consultations have been effective at improving and treating mental health conditions, including anxiety and substance abuse. The article suggests that digital phenotyping using social media could be used proactively to identify cases and monitor them for changes, is which what I’d understood the the Healthy London Partnerships Good Thinking programme had been doing for some years. There is other useful material in the edition, culminating in a paper on Dynamic prediction of psychological treatment outcomes: development and validation of a prediction model using routinely collected symptom data. There’s also interesting information on the direct and indirect impacts of Covid-19.

That sinking feeling Part III

In the continuing GPDPR debate, into which Camilla Cavendish in the FT has injected a very level-headed proposal, the Lancet has an important contribution, Health data poverty: an assailable barrier to equitable digital health care, to the debate about pointing out that without in depth anonymised data, medical research, particular digital health-related, will be seriously impaired and the digital divide will widen.

And finally…

Particular thanks to Prof Mike Short who has pointed me to many items I might otherwise have missed, and to Dr Nicholas Robinson who in spite of recovering from serious knee surgery has kindly kept up the flow of such items too.
