Ascending cloud—the role of cloud computing in
the new doctor-patient relationship
Digital technology is changing the relationship between patient and doctor, and
healthcare providers must adopt new approaches to data and information
The power dynamics of healthcare are shifting. To date, healthcare providers have been
the source and gatekeeper for all information about a patient’s health. Now, though,
consumer technology is allowing individuals to measure their own health in greater
detail, and therefore play more of an informed role in their own treatment.
Technology-driven investors see a big opportunity. In 2015, almost $1.8 billion was
invested in US start-ups focused on the consumerisation of healthcare, with investment in
personal health tools up 223%.1
The most visible tools for patients on the market are wearables with health monitoring
capabilities—for example, the more than 23 million Fitbits and iWatches that have been
sold.2
These and other devices are providing medical information directly to the patient,
with a focus on metrics that the patient can easily understand and act on—heart rate,
calorie loss, sleep patterns, exercise, etc.
An emerging generation of patient tools focuses on remote patient monitoring—patient-
based monitors that generate a continuing data feed from the patient to the doctor
and healthcare system. Sense4Baby, for example, provides expectant mothers with a
wireless foetal and maternal heart rate monitor, which is continuously linked to doctors

Ascending cloud—the role of cloud computing in the new doctor-patient relationship
through a web portal. Instead of periodic or emergency-driven check-ups, doctors can
monitor and even anticipate pediatric emergencies in real-time.
Physician acceptance of these devices is not automatic. “There are a lot of challenges
involved in getting the physician to take that data seriously. For a physician, making
clinical decisions based on that data is a challenge, potentially because of work flow
and time constraints” says Jesus Pindado, vice president of engineering at MC10, a
Cambridge, US-based company specialising in biometric devices.
However, remote monitoring technologies will only become more valuable as
populations in developed countries age, and chronic conditions such as heart disease,
diabetes, Alzheimer’s and hypertension increase in prevalence. These progressive
diseases lend themselves to a daily monitoring approach—providing more predictive
care for patients, and allowing them to receive care within their homes.
“One of the big underserved areas has been in the field of chronic disease
management—conditions such as diabetes, cardiac ailments, COPD and so on,” says
Chris Witt, president and co-founder of WAKE TSI, which provides IT services to healthcare
organisations. “If a clinical team can manage long-term critical care on an ongoing
basis, this will reduce the lines in the emergency rooms.”
The infusion of medical practice with new digital technology not only aids in the
treatment of individual patients, but may also advance medical research. For example,
a network of thousands of heart monitors can be used to detect aggregate patterns of
cardiac anomalies across populations. Connecting these monitors to hospital databases
would allow doctors and specialists to correlate arrhythmia with previous diagnoses and
medication history.
The information problem
This emerging vision of new healthcare delivery assumes that technology can meet a
number of information-related challenges.
The first is the variety of data that must be integrated to create a holistic view of a patient,
or a community of patients. In the future, patient data will be generated from the full
range of biosensors, smartphones and wearables, as well as technologies yet to come.
Healthcare providers themselves will need to use data from test machines, doctors’
tablets, MRIs and nurses’ records. Third party institutions—service providers, ambulance
operators, insurers etc.– will contribute data from their own devices, standards and
operating systems. Bringing all this data together in such a way that allows a doctor to
see all the relevant information about a particular patient is no mean feat.
The second challenge is the volume of data produced by these various sources. Every
patient is potentially a source of petabytes of medical information, all of which must be
kept for future reference to provide ongoing personalised care. Added to this challenge
is the fact that historical data may be contained in legacy and unstructured sources,
such as scanned paper documents.
A survey of 72 healthcare executives by The Economist Intelligence Unit, sponsored by
VMware, reveals that the majority view cloud computing as a crucial component of
healthcare’s technology-driven future.

Ascending cloud—the role of cloud computing in the new doctor-patient relationship
For example, over three-quarters of respondents believe that cloud computing plays a
‘somewhat’ or ‘very important’ role in enabling remote diagnosis (76%) and remote
treatment (79%), supporting the centralisation of health records (85%) and supporting
preventative care (85%).
Mr Witt believes “the cloud” will be the point of collection and integration for the mass of
medical data that healthcare providers will soon need to contend with. “Eventually all
the data from wearables, inserted monitors and the like has to come back to a central
location,” he explains. “Clinicians will access that data and potentially some analytics
programs will access that data too.”
“The benefit coming from the cloud is performance,” he adds. “Hospitals can upgrade
their performance in a pay-as-you-go model much more nimbly than they can with an
in-house data center because there’s less expenditure involved. Speed, server
performance, storage and network
operation are all enhanced, which
ultimately serves patient needs more
efficiently and effectively.”
So far, the healthcare industry has been a
slow adopter of cloud computing. Only 43%
of healthcare respondents say the
technology has a significant or pervasive
presence in their country’s healthcare
industry today. This compares to 59% and
58% of finance and retail executives
respectively who say the same of their
sectors.
This relatively low adoption by healthcare
providers is explained, in part at least, by
the sensitivity of the data they handle. No
information is more personal than details of
one’s health, and healthcare providers
have a moral and legal requirement to treat patient data with the utmost care. While
the security and privacy implications of cloud computing can be debated, companies
with more to lose should their data be compromised are typically, and understandably,
more cautious about adopting new IT platforms.
However, the healthcare sector expects adoption to grow. Eight out of ten survey
respondents (81%) believe that cloud will be a moderate or major factor in their industry
in three years’ time.
Cloud is evidently an important dimension of a technological revolution that will have far
reaching implications for the healthcare sector. This revolution promises to empower
patients to take greater control of their own health, and to allow providers to offer more
integrated and personalised care.
But it will also challenge healthcare providers to rethink their relationship with patients,
including the way they store, process and analyse their information.
