Overview
 As healthcare organizations strive to optimize their workflows and improve outcomes, they
seek new avenues that can help them overcome the inefficiencies in their current systems and
thereby extract more ROI. The key to achieve this depends on how well the providers and
payers connect with the patients to provide timely treatment and preventive care. ‘Internet of
Things’ has the potential to transform the way care is delivered, without having the patients to
step outside the comfort of their homes
 With the adoption of cloud and big data technologies, healthcare organizations are in a
position to begin experimenting with IoT. Ranging from home care to smart facilities, there are
many ways in which provider organizations can benefit by using IoT in their patient care
workflows. E.g., a mobile app with patient geo-fencing capabilities can help optimize physician
rounds by dynamically routing the physician to the nearest patient
 Payers can leverage insights generated by IoT infrastructure to improve population health,
increase patient awareness and reduce healthcare costs. Payers can also design more effective
reward and retention programs using IoT generated data.
 As IoT is evolving, adoption is slow but steady, and investments are being made by both
startups and industry leaders. Healthcare is among the top 5 industries investing in IoT.
 This document discusses how IoT can be leveraged to drive efficiencies in healthcare
workflows and enhance clinical outcomes.

Technology Considerations while Designing IoT Solutions (2/2)
Key Decision Making Criteria
while Designing IoT Solutions
 Maturity and industry
adoption of the tools and
platforms
 Standards and regulatory
compliances to adhere
 Technical skillset at
disposal

13
IoT: Security (1/2)
Tools for Securing IoT
Solutions
 Device level security
through secure booting,
integrated crypto keys
using Trusted Platform
Modules (TPMs) and
physical protection
 Secure provisioning,
identification and
decommissioning of
devices
 De-identification of
Personally Identifiable
Information (PII)
 End to end security using
SSL certificates and TLS
 Firewalls and intrusion
prevention systems
 Laying out an extensive and powerful infrastructure for
Internet of Things comes with inevitable security issues that
need careful analysis and risk evaluation
 The Dyn DDoS attack caused by Mirai malware in Oct 2016,
involving up to 100,000 endpoints reinforces the
vulnerability and importance of security measures required
for IoT solutions
 Security design principles should be rigorously implemented
to fortify the solution end to end, such as:
• Use Virtual Private Networks (VPNs) to access edge
devices
• Initiate connection from edge device to the cloud, and
not the other way round
• Allow file transfer only in one direction, if not required in
both the directions
• Double-encrypt messages with sensitive data
• Restrict access to messages that can control the device
remotely
• Implement thorough instrumentation to allow remote
monitoring of the activity

14
IoT: Security (2/2)
The EU’s General Data Protection Regulation (GDPR) will apply to IoT solutions, which mandates
aspects such as:
 Reporting of any personal data breach within 72 hours
 User’s consent for processing their data
 User’s rights for data portability and objecting to automated decision making
 Prohibition for children under 13 to provide consent for processing of their data, on their
own

15
IoT: Analytics (1/2)
 IoT business models will exploit the information collected by edge devices in many ways – for
example, to understand customer behavior, to deliver services, to improve products, and to
identify and intercept business moments.
 With the unprecedented amount of data that will be generated by these edge devices, aspects
such as storage, ownership and expiry of data becomes critical.
Choosing the right Cloud platform
Most of the cloud providers have storage and analytics offerings. Having IoT platform, storage and
analytics engine on the same cloud greatly simplifies the solution design and maintenance. Keep
in mind that since most of the IoT workflows are event driven, event processing and real-time
analytics capabilities are key features for high-volume IoT solutions.
Key Considerations
Storage v/s Streaming
Managing the data generated by billions of devices will be a significant challenge to address
during infrastructure and architecture planning. Even though cloud infrastructure will scale to
accommodate large volumes of data, it may not be effective to store all the data traffic. IoT
architectures need to evolve to perform real-time analytics on the streaming data and store only
the results, as necessary.

16
IoT: Analytics (2/2)
Distributed Analytics
As another design alternative, distributing the data analytics between the cloud, gateways and
edge devices may result in optimizations at different levels, such as reduced storage needs and
reduced network traffic. The aggregation and filtering that happens as part of the analytics
reduces PII being transmitted over the network. As a by-product, it also reduces battery
consumption of edge devices that would be used in wireless transmissions.
Ownership of Data
With increasingly vast network of sensors, IoT solutions will be able to gather tons of health,
location and activity data. IoT solution providers will need to deal with this data with great care
and consumers’ consent. Adoption of IoT will only add fuel to the discussion of ownership of data
that started with the adoption of big data in healthcare.

17
IoT: Standards and Regulations (1/2)
Implementation of an IoT solution involves a range of technologies. As multiple IoT solutions
converge together, it will be instrumental for these solutions developed by different companies
and service providers to be compatible with each other to enable reusability of infrastructure and
insights gained through the collected data.
As with any industry, standardization will bring multitude of technological and commercial
benefits:
 Standardized hardware specifications will enable mass-production of edge devices that can
operate in different geographies
 Standardized communication protocols will enable smoother integrations and reduce the
efforts spent in working around the compatibility issues
 As technologies are standardized, business models benefit from and evolve around the APIs
based on these standards
 Governments and regulatory bodies define compliance rules around these standards, which in
turn enables manufacturers and service providers to cater to larger consumer-base across
geographies

18
IoT: Standards and Regulations (2/2)
Areas of Standardization
 Connectivity protocols for nodes and gateways – TCP/IP, Wifi, Ethernet and Cellular
protocols are well established in this space. In addition, BLE and Zigbee have emerged as
lightweight and low-power alternatives
 Messaging standards – Even though HTTP is leading this front, for dealing with hardware
with lower capacity and compute powers, lightweight protocols like MQTT, CoAP and AMQP
are developed with IoT scenarios in perspective. These standards provide improved latency,
assure different levels of Quality of Service to suit the needs and consume less power
 Security standards – Security measures for hardware as well as data protection at various
layers in the IoT solution are yet to mature
 Regulatory requirements – Industry-specific regulations will evolve over time. Federal
regulatory agencies like ONC and HHS in USA will play key role in protecting the consumers
from any misuse of data

19
Key Takeaways
 Internet of Things has a lot of potential to improvise and automate existing
processes and workflows across multiple industries and healthcare
organizations are certain to be amongst the beneficiaries
 A lot of work needs to happen in terms of establishing regulations and
addressing security concerns. While these are difficult problems to solve,
industries and governments together can bolster this space by leveraging
knowledge and experiences in similar spaces
 Increasing investments and maturity in technology areas such as Cloud,
advancements in compact and smart devices, large-scale storage solutions and
wireless communication, have given IoT solutions a real shot in the arm
 On the other hand, advanced analytics and machine learning technologies are
evolving at a rapid pace to be able to consume the voluminous data that IoT
solutions can generate
 With the right ingredients in place, these are exciting times for innovators and
businesses to be a part of the IoT wave
