Smart hospitals: the future of healthcare?
The coming decade will bring unprecedented challenges for the global healthcare industry.
In addition to emergent threats like the COVID-19 pandemic, the global population is not only getting larger, it is also ageing. By 2030, the world will be home to more than 8.5 billion people. By 2050, the number of people over the age of 60 will have doubled in comparison to 2015.
“As healthier lifestyles are enhanced by significant improvements in healthcare, we’re living longer. While this is a welcome development, it does bring challenges,” according to Siemens’ report: The Age of the Smart Hospital. But what are the most daunting challenges facing the global healthcare sector, and how do industry leaders Siemens, McKinsey and Accenture propose that innovation, digital technologies and the rise of the smart hospital can meet them?
The rise of the smart hospital
“Technological enablement, digitisation, and automation are affecting industries today in profound ways,” writes Bo Chen, Axel Baur, Marek Stepniak and Jin Wang, analysts and authors of McKinsey’s report, Finding the Future of Care Provision: The Role of Smart Hospitals, “Healthcare delivery is no exception.”
As the transformative effects of Industry 4.0 bring digital transformation and new, innovative technologies to every sector, the healthcare industry is no exception. One of the most pronounced effects of this global digital transformation is the rise of “smart” infrastructure, says McKinsey, a development that is already affecting tens of thousands of cities, offices and homes around the world.
Smart infrastructure makes extensive use of emergent technologies like artificial intelligence (AI), Big Data and the Internet of Things (IoT) in order to create more integrated, efficient spaces that better suit the needs of their users and occupants.
This is no different in the healthcare space. Indeed, McKinsey states that smart hospitals are not only being used to improve care delivery within the building, but to also connect to, and contribute towards, the broader healthcare delivery ecosystem.
According to McKinsey, a host of new technologies are being integrated into hospitals and healthcare delivery, including:
- Artificial intelligence
- Precision medicine
- 3-D printing
- Augmented and virtual reality
Implementing these and other digital technologies, says McKinsey, could help to realise cost savings of over 10% of overall annual national healthcare expenditures for most OECD countries. To further evidence the potential scale of the market, it is noted that venture capital funding for digital health solutions has grown from $1bn in 2011 to over $8bn in 2018.
“For many, the term “smart” conjures images of apps, but the smart hospital is much more than that. It’s a healing environment where the increasing digitisation of the building means that the technology is working seamlessly to deliver benefits to the people connecting to it,” writes Siemens .
“In a smart hospital, the focus is on the digital systems and the potential they offer to the building itself to effectively become a member of the team.”
These digital systems can mean anything from climate control to asset tracking and patient flow management. By using powerful new technologies like digital twins and data analytics, hospital administrators can better understand the needs of both patients and staff in order to create a more seamless experience and higher standards of care.
How healthcare can safeguard itself against cyberthreats
One of the most fundamental lessons from the COVID crisis is that health should always be a priority. In a similar fashion to the human body that frequently fights off viruses and foreign invaders that intend to cause it harm, the sector itself is now a prime target for another type of external threat: cyberattacks.
The figures speak for themselves: between December and January this year, hospitals in the UK were at 89% capacity, with 7,000 fewer available beds than there usually are. As the pandemic increased pressure on hospitals, clinics, and research facilities to create a treatment for patients globally, it has left the sector exposed to hackers who, like a virus, have been targeting it relentlessly and evolving their tactics.
From patient records being held ransom, to fake emails claiming to originate from the UN WHO, the NHS, or vaccine centres, through to attacks on the cold supply chain to find out the secret formula of the COVID vaccine, the healthcare industry is facing constant cyberattacks and struggling to cope. This threat is unlikely to go away anytime soon – and as such, the industry needs to take a proactive, preventative stance to stay safe in a dynamic digital world.
The responsive nature of healthcare – particularly of hospitals – means that efficiency is crucial to the industry’s standard operations. To support this, the sector has been embracing technological advancements that can improve the quality of work, enabling staff to meet pressing deadlines, and enhancing patient care. For example, the industry has been digitising records and improving its ways of working through digital means over the past few years.
This shift is critical to offer high quality patient care; yet, it also means the sector has become more dependent on IT, which can come with a risk if cybersecurity processes employed are deemed as inadequate.
Without the correct security measures in place, the desired efficiency gains realised, can be easily lost in a heartbeat. Simply put, an elementary glitch in the system can have a tremendous ripple effect on many areas, from accessing patient records and conducting scans, to maintaining physical security and protecting the intellectual property of experimental treatment development.
To prevent this, healthcare organisations need to ensure they’re considering cybersecurity as part of their overall digital transformation strategy – and setting the right foundations to create a culture where safety goes hand in hand with patient care.
Before implementing cybersecurity process, healthcare organisations need to assess the potential risks they face. Depending on how much confidential data the trust has, where it is stored, who has access to it and via which means, the cybersecurity strategy and associated solutions will change.
It’s fair to say that a medical device start-up where all employees have a corporate-sanctioned laptop and access data via a VPN will have radically different needs to a large hospital with hundreds of frontline workers connecting to the hospital’s Wi-Fi using their personal device.
These requirements will pale by comparison to a global pharmaceutical giant with offices in multiple locations, a large R&D department researching new treatments for complex diseases and a fully integrated supply chain. Considering the existing setup and what the organisations is looking to achieve with its digital transformation strategy will therefore have an immediate impact on the cybersecurity strategy.
Despite this, there are fundamentals that any organisation should implement:
Review and test your back-up policy to ensure it is thorough and sufficient – By checking that the organisation’s back-up is running smoothly, IT teams can limit any risks of disruption in the midst of an incident and of losing data permanently.
In our recent State of Email Security report, we found that six out of ten organisations have been victims of ransomware in 2020. As a result, afflicted organisations have lost an average of six days to downtime. One third of organisations even admitted that they failed to get their data back, despite paying the ransom. In the healthcare industry, this could mean losing valuable patient records or data related to new treatments – two areas the sector cannot afford to be cavalier about.
Conduct due diligence across the organisation’s supply chain – Healthcare organisations should review their ways of working with partners, providers and regulatory institutions they work with in order to prevent any weak link in their cybersecurity chain. Without this due diligence, organisations leave themselves exposed to the risks of third party-led incidents.
Roll out mandatory cybersecurity awareness training - Healthcare organisations shouldn’t neglect the training and awareness of their entire staff – including frontline workers who may not access the corporate network on a regular basis. According to our State of Email Security report, only one fifth of organisations carry out ongoing cyber awareness training.
This suggests it is not widely considered as a fundamental part of most organisations cyber-resilience strategy, despite the fact many employees rely on their organisation’s corporate network to work. By providing systematic training, healthcare organisations can help workers at all levels better understand the current cyberthreats they face, how they could impact their organisation, the role they play in defending the networks, and develop consistent, good cybersecurity hygiene habits to limit the risks of incidents.
Consider a degree of separation – Information and Operational Technology (IT and OT) networks should be separated.
Although mutually supported and reliance on each other, employees shouldn’t be accessing one via the other. This should be complemented by a considered tried and tested contingency and resiliency plan that allows crucial services to function unabated should there be a compromise. Similarly, admin terminals should not have internet access to afford a degree of hardening and protection for these critical accounts.
As the sector becomes a common target for fraudulent and malicious activity, putting cybersecurity at the core of the organisation’s operations is critical. It will help limit the risks of disruption due to cyberattacks, reduce time spent by the cybersecurity team to resolve easily avoidable errors, and ensure that institutions can deliver patient care, safe in the knowledge that their networks are safe.
Fighting future threats
With technology continuing to change the face of healthcare, the surface area and vectors available for attacks by malicious actors is constantly increasing. With the introduction of apps, networked monitoring devices, and a need for communication, the attack vector is ever expanding, a trend that needs to be monitored and secured against.
To prevent any damage to patients, staff, or the organisation they are responsible for, healthcare leaders must put security front and centre of their digital transformation strategy. Only then can the sector harness the full benefits of technology. Doing this should include implementing cybersecurity awareness training to challenge misconceptions around security, encourage conversation, and to ensure employee knowledge of the security basics and threats faced.
This ultimately allows healthcare organisations to do what they do best: provide the highest standard of patient care, safe in the knowledge that their operations, patients, and data are safe.
