‘A bit bit sci-fi’: How robots could make a dent in nurses’ workloads

Frontline healthcare staff are stretched skinny within the wake of the COVID-19 pandemic as many hospitals cope with nursing shortages and provider burnout.

Diligent Robotics, which earlier this week introduced a $30 million Series B funding round, goals to minimize a few of that staffing burden by automating routine supply duties with its Moxi robotic. The corporate’s CEO and cofounder, Andrea Thomaz, sat down with MobiHealthNews to debate how Moxi works, what it takes to onboard a robotic hospital employee and the way Moxi’s design informs its interactions with people. (This interview has been edited for readability and size.)

MobiHealthNews: Are you able to inform me a bit about how Moxi works and the way it assists healthcare suppliers in hospitals?

Andrea Thomaz: Moxi is what’s known as in robotics a cellular manipulation robotic. That simply means it is bought a cellular base, an arm that may manipulate issues within the setting and a socially expressive head that lets individuals know what Moxi is doing. 

Moxi is doing fetch-and-deliver duties for hospital workers. We prefer to say that Moxi could be put in to be fairly versatile and go point-to-point within the hospital. And we find yourself saving individuals plenty of time by taking up the entire advert hoc supply duties that occur all through the day.

So it is delivering lab samples from between the nursing unit and the central lab, or taking on drugs from the pharmacy, light-weight gear from central provide, or a lunchbox from meals and diet. So it is simply plenty of issues that fall onto the plates of folks that have significantly better issues to do.

MHN: Why did you resolve to deal with implementing robotics in healthcare, notably for that fetch-and-delivery house?

Thomaz: My cofounder and I are each deep consultants in robotics, not in healthcare. However our experience is in human-robot interplay, and specifically, fascinated by robots interacting with a workforce of individuals. So we have been on the lookout for a spot to essentially develop that teamwork robotic. 

I feel hospitals are only a implausible instance of this, with a real workforce scarcity. Immediately, with state-of-the-art robotics know-how, there’s not a single job within the hospital that you can think of a robotic doing that complete job. However you’ll be able to give you a number of completely different annoying duties which are falling onto the plates of plenty of completely different individuals, and we will automate these out of plenty of completely different individuals’s jobs. 

That is actually the thrilling half to us as roboticists, it is discovering that collaboration between a robotic and a workforce of individuals. And so we work with hospital management to establish all of these alternatives, and strategize which of them are those we need to hit first. After which we roll out newly automated workflows to all these groups.

MHN: So that is customized relying on what every hospital thinks they want, or what’s most vital to them, or what their drawback areas are of their hospital?

Thomaz: Yeah, and you will see that we truly redesigned our software program just a little bit to be much more versatile from once we first deployed it. We realized that we did not must have particular software program for lab deliveries and one other piece of software program for pharmacy, we truly wished it to be extra generic than that, in order that we will actually simply take into consideration the entire hospital as any waypoints that folks wished to set.

Then we may begin sending the robots to and from any of them. And what that permits us to do is let the hospital actually resolve what’s most vital, and we work with them on that sort of change administration.

We do see that there is plenty of consistency throughout organizations in regards to the typical medical workflows which have challenges. For instance, for those who’re an infusion clinic, then getting these infusion meds on your chemo sufferers. These are meds which are combined simply in time, and so that you need to get them to your affected person as quickly as they have been combined.

And in order that’s an amazing instance of a workflow that’s sometimes hand-carried drugs in hospitals. We’ve plenty of curiosity in automating that workflow, since you’re taking both a beneficial pharmacy tech or a beneficial nurse’s time to run infusion meds. 

However what’s going to be extra strategically a precedence is completely different from hospital to hospital. It will be depending on their affected person inhabitants, depending on their structure. If in case you have a structure such that you’ve three nursing towers, and the principle pharmacy is in one in every of them, you then higher imagine that your two nursing towers do not have the pharmacy within the basement. They’re struggling.

And so that could be like the best worth workflow for you, as a result of that is the place you see plenty of your workers operating round.

MHN: How do suppliers normally reply to Moxi whenever you’re first beginning to implement it? Is there sort of a studying curve for them?

Thomaz: We have truly been pleasantly stunned at how accepting individuals are of the know-how. I feel, from the tip person’s [perspective], just like the individuals which are truly utilizing Moxi for deliveries, they see straight away the worth.

After we first arrive, we at all times carry the robotic round on an introduction. It is normally the nursing management that is rounding with Moxi and introducing Moxi to the workforce and saying, “Hey, Moxi is becoming a member of the workforce. This is the reason we have introduced this robotic right here. We actually worth your time, and we need to discover ways in which we will have this robotic doing issues for you, as a substitute of getting you operating round.”

And so then all people will get it. However I feel that first day, there’s just a little little bit of like, “Wait, what? This truly works?” It feels just a little bit sci-fi to individuals. 

After we get the robotic mapped and programmed and we’re able to go reside, we spend one other two weeks or so doing apply deliveries and duties with the workers. Moxi will carry water to everybody or ship sweet or let individuals ship notes backwards and forwards to one another. So we perform a little little bit of simply giving all people an opportunity to strive it in a low stress, low affect sort of means. And that means all people feels actually snug on day one.

We put plenty of thought into the design. I feel a part of that was as a result of we wish it to be one thing that is good to be round, however there’s additionally a practical side for the best way the face is and the best way the pinnacle strikes specifically. A number of the options that we designed into Moxi to make it match into the setting higher are simply the footprint, how massive the robotic is.

It is fairly small in comparison with a supply robotic that you’d see in a warehouse. We actually need it to be sufficiently small to suit in every single place that folks go. We additionally made certain that the robotic stands about 4 and a half ft tall. We wished to verify it wasn’t taller than anybody. There’s nonetheless some actually brief individuals that can run into that, but it surely’s typically sort of unassuming. However it’s massive sufficient to hold a major set of issues. 

After which the pinnacle itself strikes round. It is just a little bit refined why that is vital. A few good examples are when the robotic is coming down the hallway and is making ready to show left, it will look earlier than it goes someplace. So everybody within the setting is aware of this robotic goes to show left, not proper.

Identical is true for when the robotic goes to succeed in out and push a button to open a door for instance, the robotic can be standing there in entrance of the door, after which it sort of seems to be on the button and pushes it. That notion of individuals having the ability to infer what the robotic’s fascinated by or what the robotic’s doing is an enormous a part of the design.

MHN: I do know that it makes little “meep” sounds, proper? Is that the way it communicates with the nurses or different suppliers?

Thomaz: So we do have meeps and beeps and lights and issues. We attempt to restrict the quantity of pure language English interactions that it is having with individuals. We simply do not need to over-communicate its intelligence. 

There are a couple of completely different occasions the place it should say a particular phrase, like “I am right here for a pickup,” or “I am getting off on ground quantity three.” It is simply the simplest solution to talk that data.

There’s additionally an iPad on the entrance of the robotic, and so among the ways in which individuals work together with it are on display as properly.

MHN: What are among the challenges that you just needed to overcome when utilizing Moxi in a healthcare setting? 

Thomaz: Individuals are quick. They’re transferring round, they’re altering the place issues are situated, they’re choosing issues up and transferring them round. So the robotic can’t assume that issues are going to remain the identical.

So the software program that we write – the AI, machine studying notion software program – is basically geared at this: Look, I will assume that I do know the place the partitions are within the hospital, so I could make a plan of get from one place to a different. However 60 occasions a second, I’ve to guage the state of affairs to see if there’s an individual strolling by or a mattress within the hallway.

The opposite factor that is actually completely different from a warehouse – the place you may have simply an open setting the place the robotic is attempting to get from one place to a different – is, within the hospital we’ve got to utilize the infrastructure of the hospital. So we’ve got to have the ability to open doorways and be capable to experience elevators. And in order that’s the place the usage of the arm and the manipulation comes into play.

MHN: So that you simply introduced your $30 million Collection B. How are you planning on utilizing that funding?

Thomaz: We’re excited to essentially have the chance to scale the workforce, each the engineering workforce and the gross sales and operations workforce, to fulfill the rising demand. 

Over the past 12 months, we have seen a dramatic improve in demand. Earlier than the pandemic and even within the first yr of the pandemic, we have been actually extra of an innovation challenge. If any person was reaching out to us to work collectively, it was as a result of they’d an innovation funds that they have been seeking to do one thing cool and new.

Now, we’re having CIOs attain out to us on our web site, like chilly outreach, saying, “Hey, I must implement a robotic technique for my hospital. I need to hear about your answer.”

So I might say that robotics and automation have gotten simply rather more mainstream in hospitals and healthcare. And so we’re excited to develop and be capable to meet that demand and simply get extra robots out quicker.
