Going virtual to combat COVID-19

Like many of you, I am working from home during the COVID-19 pandemic and have limited my movement to an absolute minimum. Yet despite being in a high-risk self-isolating category, I am not isolated. I continue to be in ‘virtual’ touch with colleagues, customers, friends and family. We are hearing the first stories of acquaintances who have contracted the virus or have already lost loved ones. If you are one of them, I wish you strength in these unsettling times. With enormous stress on healthcare systems around the globe, it is more urgent than ever before to step up collaboration, information and knowledge sharing, and agility in the delivery of diagnostic, respiratory and monitoring solutions at scale. 

How Philips is helping in the fight against COVID-19

Our CEO Frans van Houten released a statement recently on how our company is responding to the constantly evolving COVID-19 situation. From my home, together with my colleagues around the globe, we are working around the clock to deliver ventilators, monitors, diagnostic equipment and virtual care solutions to support our amazing care providers in their endless efforts to help patients. We have ramped up the production of ventilators, monitors and solutions to help diagnose and treat patients. At the same time, we are helping hospitals to increase their number of ICU beds to accommodate the most critical and acute coronavirus patients. 

People around the globe are doing everything they can to contain COVID-19 or at least slow down the rate of infection. We should all adhere to the guidelines on social distancing and hygiene and stay up-to-date with the latest information from trusted healthcare sources, so we can act as responsible citizens in a fast-changing situation. The guiding principle for information is that it should be transparent and evidence-based. And one of our most powerful instruments for evidence-based healthcare is the technology to collect, qualify and analyze data in ways that quickly reveal patterns and hidden insights. It highlights the need for robust health-data infrastructures. In the Netherlands, we have contributed to the launch of a COVID-19 data exchange portal that connects providers to support patient transfers. It enables that a patient’s data is easily though securely transferred via the cloud from hospital A to B.

Another valuable instrument for coping with a rapidly spreading infection like COVID-19 is ‘virtual care’, sometimes referred to as telehealth. With the large number of patients involved and the face-to-face risk of infecting other patients and staff, online consultations can provide valuable relief to the healthcare system. Philips has made available a dedicated scalable telehealth solution that facilitates the use of online patient screening and monitoring, supported by external call centers. The solution aims to prevent unnecessary visits to general practitioners and hospitals by remotely monitoring the vast majority of COVID-19 patients that are quarantined at home. Patients infected with COVID-19 can be remotely monitored via smart questionnaires about their home situation and state of health, identifying if intervention is needed.

In the current situation, where COVID-19 occasionally results in severe pneumonia, there will be an increasing number of patients requiring acute care in hospital or in an intensive care unit (ICU). The numbers swelling to unmanageable proportions is already happening in many countries and remains a real worry for healthcare authorities around the world, not simply because of the limited number of ICU beds and ventilators but also because of staff shortages and burn-out. Trained ICU doctors and nurses are already in short supply and repeated exposure to infected patients will increase their own risk of contracting the virus.

How COVID-19 is spurring the move to virtual care

A tele-ICU or eICU enables a co-located team of intensivists and critical care nurses to remotely monitor patients in the ICU regardless of patient location. Intensivists and nurses based in a telehealth eICU hub are supported by high-definition cameras, telemetry, predictive analytics, data visualization and advanced reporting capabilities in order to support their frontline colleagues. Algorithms alert to signs of patient deterioration or improvement. They help care teams to proactively intervene at an earlier stage or to decide which patients have stabilized and can be transferred, allowing scarce ICU beds to be allocated to more acute patients. The tele-ICU can be embedded in a larger Clinical and Operations Center that prioritizes patients on acuity and optimizes the patient flow and logistics. 

Solutions like these enable more COVID-19 patients to receive care. As we speak, we are helping hospitals with installed eICUs to expand their reach and exchange important information about COVID-19 indicators and protocols. We are supporting others to expand the reach of their ICUs into other settings. Northwell Health recently gave a webinar, during which its clinicians shared their experiences of using their eICU for patients with COVID-19. 

Advanced telemetry and camera technologies hold out the promise of monitoring acute patients at scale. In the near future, you can expect image analysis software that measures an ICU patient’s temperature, heart rate and respiration rate from a distance of several meters. Using existing patient monitoring solutions, AI is already able to use the acquired data to predict when a patient’s condition is about to deteriorate, hours before a nurse would be able to spot it. And when patients do deteriorate, secure connections to external clinical experts allow appropriate treatment plans to be initiated. When there are staff shortages, such as reduced availability of night-shift staff, monitoring can be done from remote locations, even halfway across the world where people are wide awake. We are already deploying vital signs camera technology to detect deterioration in patients waiting in emergency department waiting rooms so they can receive quick attention. 

The remote monitoring approach can also be extended to the home, with smart wearables tracking patients who are infected or at risk of infection. These wearables, like a smart patch, can measure body temperature, respiration rate and heart rate, monitor sleep and detect falls. All these measurements can be combined with contextual and behavioral information about the patient to keep them as safe as possible. We are working on rapidly deployable solutions like these for (at risk) patients.
