Last Friday, the WannaCry malware wreaked havoc on the U.K’s NHS. We carry a collection of articles this week on the aftermath, including my blog in CIO online on this.

It appears that the US health system was largely spared due to the fragmented and decentralized structure of the industry and the lack of interoperability between systems which makes it harder for malware to spread quickly.

However, several questions arise from the incident: how vulnerable is U.S healthcare? What is the responsibility of the software vendor in these incidents? what is the liability of the health system when patient data is breached by ransomware?

The bottom line is that healthcare in the U.S remains vulnerable and largely apathetic toward IT security. Medical devices appear to be a particularly vulnerable part of the US healthcare system.

Cognitive and AI are steadily gaining ground in healthcare, but face some challenges as well (read my blog from earlier this year, and also a couple more here and here). At the IBM Watson Health user conference this week in beautiful Boca Raton, Fla, I had the opportunity to meet with healthcare CEOs, clinical practitioners, and technologists. Here are some soundbites:

– The one word that describes healthcare: fragmentation.
– Lasting change in healthcare likely to come from economic and political forces
– Consumerism is being driven by the democratization of medical information
– Technology needs to be able to present insights from data without the data
– Healthcare consumers are “predictably irrational”.
– Value creation and maximization are driven by emotional and social biases among patients and caregivers.
– Scaling new healthcare delivery models is impossible without technology. However, most technologies lack behavioral inputs.

Here’s why designing a healthcare app needs to be more about prioritizing the interests of the user.
