Can chatbots ease the burden on healthcare during COVID-19?
New research has found that chatbots could help ease the pressures the COVID-19 pandemic has placed on hospitals and the healthcare system...

Chatbot technology could be used to screen patients for symptoms of COVID-19, according to new research into AI technology by Sezgin Ayabakan, a faculty member at Temple University’s Fox School of Business. The virtual assistants use learning algorithms to analyse answers provided by patients, helping to free up time for healthcare workers who have become overwhelmed since the pandemic began so they can focus their care on serious cases, while reducing unnecessary admissions to hospitals. 

Ayabakan explained: “The main goal is that we hope chatbots can be used to screen patients for COVID-19, so the healthcare workers can deal with more severely ill patients rather than screening folks with mild conditions over the phone. There is a huge burden on the healthcare system. When we did this experiment in April, we did it with the hope that our findings might help alleviate that burden.”

His research paper “User reactions to COVID-19 screening chatbots from reputable providers” is co-authored by Fox School doctoral candidate Mohammad Rahimi, as well as Indiana University Kelley School of Business faculty members Alan Dennis and Antino Kim. It was recently accepted for publication in the Journal of the American Medical Informatics Association. 

The study included input from 371 participants who viewed a COVID-19 screening session with a hotline agent, who could be either a human or a chatbot. They were then asked for their thoughts. 

Ayabakan, who is also an assistant professor of Management Information Systems, explained: “We showed a vignette to half of the participants and said, ‘This conversation is between an individual and a chatbot agent’ and then with the others, we said, ‘This conversation is between an individual and a human agent,’” says Ayabakan, an assistant professor of Management Information Systems. “We wanted to see how people perceived this conversation. We tried to capture their bias.”

Participants initially had a negative bias towards the chatbots, however this changed if the provider was someone they knew and trusted; in this case the Centers for Disease Control and Prevention (CDC).

“What we found was that if they trusted the provider, their ability to trust the provider’s chatbot service increased greatly. So we found that folks seem to really trust the CDC, which then increased the trust they had in the online screening services,” Ayabakan says. “For this to work, we really need to emphasize the source or provider, so that participants will use the chatbot and follow its advice.”

Ayabakan concluded that as long as the chatbot was able to perform its job as well as the human agent, users viewed the virtual assistant no differently and trusted the technology.

Separate research from Ayabakan’s colleague and fellow Fox School faculty member, Xueming Luo on similar AI technology, drew parallel conclusions. His article “Machines versus Humans: The Impact of AI Chatbot Disclosure on Customer Purchases” found that chatbots are especially effective when it is not revealed that the agent is a chatbot.

Ayakaban believes that his research into virtual assistants and machine learning algorithms will benefit the healthcare industry moving forward, as screening for COVID-19 is likely to continue for some time.

We chart Zoom's rise and entrance into the healthcare market

Since the pandemic began Zoom has become an integral part of daily life for people working from home, as well as a vital tool for families and friends to communicate. However it's also been eyeing up the healthcare space since 2017, and following the boom in telehealth the company has been rolling out additional services. Here we chart Zoom's move into healthcare. 

2011 - 2013


Zoom is founded in San Jose, California, by Eric Yuan, formerly of Cisco. He got the idea to create a video calling platform from his visits to his girlfriend while he was a student, which would take 10 hours by train. 

A beta version is released in 2012, which can host up to 15 participants. In 2013 this rises to 25. By mid-2013, Zoom has 1 million users. 

2014 - 2017

Zoom attracts investors, including Sequoia Capital, Emergence and Horizon Ventures. By January 2017, Zoom has a series D funding worth $100 million.

2017 - 2019

Zoom for Telehealth launches, including an integration with EHR system Epic. It has cloud-based video, audio, and content sharing features, a "waiting room" for patients, and can easily be integrated into healthcare provider's workflows. 

In 2019 Zoom goes public, with its IPO rising 72% in one day. 

2020

As a result of the pandemic, Zoom gains 2.2 million new users, more than in the whole of 2019. On the 23rd of March alone - the day the UK lockdown was announced - the platform was downloaded 2.13 million times around the world. 

Share prices rise to around $150, and founder and chief executive Eric Yuan becomes one of the world's richest people, with an estimated net worth of $7.9 billion. 

Early security issues are addressed by encrypting data with the Advanced Encryption Standard (AES). By now the the platform allows 99 people to be on a call simultaneously
New features launch, including Zoom Home and Zoom for Chats. Throughout the year the platform is used to replace most kinds of real life events: work meetings, online classrooms, church services and social events. 

2021

Renamed Zoom for Healthcare, users can share secured video, audio, and content through desktops, mobile phones, and conference devices. As well as Epic, it can be integrated with Strmr, IntakeQ, and Practice Better.

It can also be used with diagnostic cameras and other point-of-care devices, including digital stethoscopes.

In an interview with Korea Biomedical Review, Zoom Global Healthcare Lead Ron Emerson said: "Our service is not simply a virtual care and telemedicine platform but a multi-purpose platform that can satisfy the needs of healthcare institutions."

"It can be used for administrative tasks, including telemedicine, medical team meetings, recruitment, medical education, employee training, and disease prevention. Analysing electronic records managed by Zoom could provide meaningful insights into patient care." 

Phoenix Children's Hospital, Belfast's Hospital Services Limited, Butler Health Services and the global Project ECHO are among Zoom for Healthcare's current customers.
