Dana Gardner: Hi, this is Dana Gardner, Principal Analyst at Interarbor Solutions, and you’re listening to BriefingsDirect. Our next healthcare insights discussion explores the shift medical services providers are making to improve the overall patient experience.

Gardner
Taking a page from modern, data-driven industries that emphasize consumer satisfaction and ease, a major hospital in the New York metro area has embarked on a journey to transform healthcare-as-a-service.

To learn more about the surging importance and relevance for improving patient experiences in the healthcare sector using the many tools available to other types of businesses, we are joined by Laura Semlies, Vice President of Digital Patient Experience, at Northwell Health in metro New York, and Julie Gerdeman, President at HealthPay24 in Mechanicsburg, Penn. Welcome to you both.

What are the trends driving a makeover in the overall medical patient experience?

Semlies: The trend we’re watching is recognizing the patient as a consumer. Now, healthcare systems are even calling patients “consumers” -- and that is truly critical.


In our organization we look at [Amazon founder and CEO] Jeff Bezos’ very popular comment about having “customer obsession” -- and not “competition obsession.” In doing so, you better understand what the patient needs and what the patient wants as a consumer. Then you can begin to deliver a new experience. 

Gardner: This is a departure. It wasn't that long ago when a patient was typically on the receiving end of information and care and was almost expected to be passive. They were just off on their way after receiving treatment. Now, there’s more information and transparency up-front. What is it about the emphasis on information sharing that’s changed, and why?

Power to the patients


Semlies: A lot of it has to do with what patients experience in other industries, and they are bringing those expectations to healthcare. Almost every industry has fundamentally changed over the course of a last decade, and patients are bringing those changes and expectations into healthcare. 

Semlies
In a digital world, patients expect their data is out there and they expect us to be using it to be more transparent, more personalized, and with more curated experiences. But in healthcare we haven’t figured it out just yet -- and that’s what digital transformation in healthcare means. 

How do you take information and translate it into more meaningful and personalized services to get to the point where patients have experiences that drive better clinical outcomes?

Gardner: Healthcare then becomes more of a marketplace. Do you feel like you’re in competition? Could other providers of healthcare come in with a better patient experience and draw the patients away?

Semlies: For sure. I don’t know if that’s true in every market, but it certainly is in the market that I operate in. We live in a very competitive market in New York. The reality is if the patient is not getting the experience they want, they have choices, and they will opt for those choices. 

A recent study concluded that 2019 will be the year that patients choose who renders their care based on things that they do or do not get. Those things can range from the capability to book appointments online, to having virtual visits, to access to a patient portal with medical record information -- or all of the above. 

And those patients are going to be making those choices tomorrow. If you don’t have those capabilities to treat the patient and meet their needs -- you won't get that patient after tomorrow.

Gardner: Julie, we're seeing a transition to the healthcare patient experience similar to what we have seen in retail, where the emphasis is on an awesome experience. Where do you see the patient experience expanding next? What needs to happen to make it a more complete experience?

Gerdeman: Laura is exactly right. Patients are doing research upfront before providers interact with them, before they even call and book an appointment. Some 70 percent of patients spend that time to look at something online or make a phone call.

Competitive, clinical customer services


We’re now talking about addressing a complete experience. That means everything from up-front research, through the clinical experience, and including the financial and billing experiences. It means end-to-end, from pre-service through post-service.

Gerdeman
And that financial experience needs to be at or better than the level of experience they had clinically. Patients are judging their experience end-to-end, and it is competitive. We hear from healthcare providers who want to keep patients out of their competitors’ waiting rooms. Part of that is driving an improved experience, where the patient-as-consumer is informed and engaged throughout the process. 

Financially speaking, what does that mean? It means digital engagement -- something simple, beautiful, and mobile that’s delivered via email or text. We have to meet the consumer, whenever, and wherever they are. That could be in the evening or early in the morning on their devices. 
That’s how people live today. Those personalized and curated experiences with Google or Alexa, they want that same experience in healthcare.

Gardner: You don’t want a walk into a time machine and go back 30 to 40 years just because you go to the hospital. The same experience you can get in your living room should be there when you go to see your doctor. 

Laura, patient-centric care is complicated enough in just trying to understand the medical issues. But now we have a growing level of complexity about the finances. There are co-pays, deductibles, different kinds of insurance, and supplemental insurance. There are upfront cost estimates versus who knows what the bill is going to be in six months.

How do we fulfill the need for complete patient-centric services when we now need to include these complex financial issues, too?
Learn How to Meet Patient Demands
For Convenient Payment Options
For Healthcare Services
Semlies: One way is to segment patients based on who they are at any moment. Patients can move very quickly from a healthy state to a state of chronic disease management. Or they can go from an episode where they need very intense care to quickly being at home.
First, you need to understand where the patients’ pain points are across those different patient journeys.

Second is studying your data and looking back and analyzing it to understand what those ranges of responsibility look like. Then you can start to articulate and package those things. You have more norms to do early and targeted financial counseling.

The final part is being able to communicate, even as things change in a person’s course of treatment, and that has an impact on your financial responsibility. That kind of dialogue in our industry is almost non-existent right now.

Sharing data and dialogue


Among the first things patients look for is via searches based on their insurance carrier. Well, insurance isn’t enough. It’s not enough to know you are going to see doctor so-and-so for x with insurance plan B. You need to know far more than that to really get an accurate sense of what’s going on. Our job is to figure out how to do that for patients.

We have to get really good at figuring out how to deliver the right level of detail on information about you and what you are seeking. We need to know enough about our healthcare system, what are the costs are and what the options are so that we can engage in dialogue.

It could be a digital dialogue, but we have to engage in a dialogue. The reality is we know even in a digital situation that patients only want to share certain amount of information. But they also want accurate information. So what’s that balance? How do you achieve that? I think the next 12 to 18 months is going to be about figuring that out.

Transparency isn’t only posting a set of hospital charges; it’s just not. It’s a step in the right direction. There is now a mandate saying that transparency is important, and we all agree with that. Yet we still need meaningful transparency, which includes the ability to start to control your options and make decisions in association with a patients’ financial health goals, too.

Gardner: So, the right information, to the right person, in the right context, at the right time. To me, that means a conversation based on shared data, because without data all along the way you can’t get the context.

What is the data sharing and access story behind the patient-centric experience story?
One of the biggest problems right now is the difference between an explanation of benefits and a statement. They don't say the same thing, and are coming from two different places. It's very difficult to explain to a patient.

Semlies: If we look at the back-end of the journey, one of the biggest problems right now is the difference between an explanation of benefits and a statement. They don’t say the same thing, and they are coming from two different places. It’s very difficult to explain everything to a patient when you don’t have that explanation of benefits (EOB) in front of you. 

What we’re going to see in the next months and years -- as more collaboration is needed between payers and health systems and providers – is a new standard around how to communicate. Then we can perhaps have an independent dialogue with a patient about their responsibilities. 

But we don’t own the benefits structure. There are a lot of moving parts in there. To independently try to control that conversation across health systems, we couldn’t possibly get it right.

So one of the strategies we are pursuing is how do we work with each and every one of our health systems to try and drive innovation around data sharing and collaboration so that we can get the right answer for a shared patient. 

That “consumer” is shared between us as providers as well as the payer plan that hosts the patient. Then you need to add another layer of extra complexity around the employer population. Those three players need to be working carefully together to be able to solve this problem. It’s not going to be a single conversation.

Gardner: This need to share collaborative data across multiple organizations is a big problem. Julie, how do you see this drive for a customer-centric shared data equation playing out?

Healthy interoperability 


Gerdeman: Technology and innovation are going to drive the future of this. It's an opportunity for companies to come together. That means interoperability, whether you're a payments provider like HealthPay24, or you're providing statement information, you're providing estimates information. Across those fronts, all of that data relates to one patient. Technology and innovation can help solve these problems.

We view interoperability as the key, and we hear it all the time. Northwell and our other provider customers are asking for that transparency and interoperability. We, as part of that community, need to be interoperable and integrate in order to present data in a simple way that a consumer can understand. 

When you’re a consumer you want the information that you need at that moment to make a decision. If you can get it proactively -- all the better. Underlying all this, though, is trust. It’s something I like to talk about. Transparency is needed because there is lack of trust.

Transparency is just part of the trust equation. If you present transparency and you do it consistently, then the consumer -- the patient -- has trust. They have immediate trust when they walk into a provider or doctor’s office as a patient. Technology has an opportunity to help solve that.

Gardner: Laura, you’re often at the intercept point with patients. They are going to be asking you – the healthcare provider -- their questions. They will look to you to be the funnel into this large ecosystem behind the scenes.

What would you like to see more of from those other players in that ecosystem to make your job easier, so that you can provide that right level of trusted care upfront to the patient?

Simplify change and choice


Semlies: Collaboration and interoperability in this space are essential. We need to see more of that.

The other thing that we need -- and it's not necessarily from those players, but from the collective whole -- is a sense of modeling “if-then” situations. If this happens what will then happen?

By leveraging from such process components, we can remodel things really well and in a very sophisticated fashion. And that can work in many areas with so many choices and paths that you could take. So far, we don't do any of that in price transparency with our patients. And we need to because the boundaries are not tight.

What you charge – from copay to coinsurance – can change as you're moving from observation to inpatient, or inpatient back to observation. It changes the whole balance card for a patient. We need the capability to model that out and articulate the why, how, and when -- and then explain what the impact is. It's a very complicated conversation.

But we need to figure out all of those options along with the drivers of costs. It has to be made simple so that patients can engage, understand, and anticipate it. Then, ultimately, we can explain to them their responsibility.

I often hear that patients are slow to pay, or struggle to pay. Part of what makes them slow to pay is the confusion and complexity around all of this information. I think patients want to pay their share.

Earn patients’ trust

It’s just the complexity around this makes it difficult, and it creates a friction point that shouldn't be there. We do have a trust situation from an administrative perspective. I don't think our patients trust us in regard to the cost of their care, and to what their share of the care is. 

I don’t think they trust their insurers and payers tremendously. So we have to earn trust. And it’s going to mean that we need to be way more accurate and upfront. It’s about the basics. Did you give me a bill that I can understand? Did I have options when I went to pay it? We don’t even do that easy stuff well today.

I used to joke that we should be paying patients to pay us because we make it so difficut. We are now in a better place. We are putting in the foundation so that we can earn trust and credibility.
I used to joke that we should be paying patients to pay us because we made it so difficult. We are now in a better place. We are putting in the foundation so that we can earn trust and credibility. We are beginning the dialogue of, “What do you need as a patient?” With that information, we can go back and create the tools to engage with these patients. 

We have done more than 1,000 hours of patient focus group studies on financial health issues, along with user testing to understand what they need to feel better about their financial health. There is clinical health, there are clinical outcomes -- but there is also financial health. Those are new words to the industry.

If I had a crystal ball, I’d say we’re going to be having new conversations around what a patient needs to feel secure, that they understood what they were getting into, and that they knew about their ability to pay it or had other options, too.

Meet needs, offer options

Gerdeman: Laura made two points that I think are really important. The first is around learning, testing, and modeling -- so we can look at the space differently. That means using predictive analytics upfront in specific use cases to anticipate patient needs. What do they need, and what works? 

https://www.northwell.edu/
We can use isolated, specific use-cases to test using technology -- and learn. For example, we have offered up-front discounts for patients. If they pay in full, they get a discount. We learned that there are certain cases where you can collect more by offering a discount. That’s just one use-case, but predictive analytics, testing, and learning are the key. 

The second thing that is dead-on is around options. Patients want options. Patients want to know, “Okay, what are my choices?” If that’s an emergency situation, we don’t have the option to research it, but then soon after, what are the choices?

Most American consumers have less than $500 set aside for medical expenses. Do they have the option of a self-service and flexible payment plan? Can they get a loan? What are their choices to make an informed choice? Perhaps at home at their convenience.

Those are two examples where technology can really help play a role in the future. 

Gardner: You really can’t separate the economics from healthcare. We’re in a new era where economics and healthcare blend together, the decision-making for both of them comes together.
We talked about the need for data and how it can help collaboration and process efficiency. It also allows for looking at that data and applying analytics, learning from it, then applying those lessons back. So, it’s a really exciting time.

But I want to pause for a moment. Laura, your title of “Vice President of Digital Patient Experience” is unique. What does it take to become a Vice President of Digital Patient Experience?

Journey to self-service 

Semlies: That is a great question. The Digital Patient Experience Office at Northwell is a new organization inside of the health system. It’s not an initiative- or a program-focused office where it’s one and done, where you go in and you deliver something and then you’re done. 

We are rallying around the notion that the patient expects to be able to interact with us digitally. To do so we need to transform our entire organization -- culturally, operationally, and technically to be able accommodate that transformation. 

Before, I was responsible for revenue cycle transformation of the Northwell Health system. So I do have a financial background. However, what set me up for pursuing this digital transformation was the recognition that self-service was going to disrupt the traditional revenue cycle. We need to have a new capability around self-service that inherently allows the consumer to do what they want and need to manage their administrative interactions differently with the health system.
See the New Best Practice
Of Driving Patient Loyalty
Through Estimation
I was a constant voice for the last decade in our health system, saying, “We need to do this to our infrastructure so that we can be able to rationalize and standardize our core applications that serve the patient, including the revenue cycle systems, so that we can interoperate in a different way and create a platform by which patients can self-serve.”

And we’re still in that journey, but we’re at a point where we can begin to engage very differently. I’m working to solve three fundamental questions at the heart of the primary pain-points, or friction points, that patients have.

Patients tell us these three things: “You never remember who I am. I have been coming here for the last 10 years and you still ask me for my name, my date of birth, my insurance, my clinical history. You should know that by now.”

Two, they say, “I can't figure out how to get in to see the right doctor at the right time at the right location for me. Maybe it’s a great location for you, or a great appointment time for you. But what if it doesn't work for me? How do I fix that?”

And, third, they say, “My bills are confusing. The whole process of trying to pay a bill or get a question answered about one is infuriating.”

Whenever you talk to anyone in our health system -- whether it’s our chief patient experience officer, CEO, chief administrative officer, or COO -- those are the three things that were also coming out of customer service, Press Ganey [patient satisfaction] results, and complaints. When you have direct conversations with patients, such as through family advisory councils, the complaints weren’t about the clinical stuff.

Digital tools to ease the pain

It was all on the administrative burden that we were putting on patients, and this anonymity that patients were walking through our halls with. Those are what we needed to focus on first. And so that’s what we’re doing.

We will be bringing out a set of tools so our patients will be able to, in a very systematic way, negotiate appointment management. They will be able to view and manage their appointments online with the ability to book, change, and cancel anything that they need to. They will simply see those appointments and get directions to those appointments and communicate with those administrative officers.

The second piece of the improvement is around the, “You never remember who I am” problem, where they have been to a doctor and get the blank clipboard to fill out. Then, regardless of whether they were there yesterday or went to see a new doctor, they get the same blank clipboard.

We’re focused on getting away from the clipboard to remembering information and not seeking the same information twice -- only if there is the potential that information has changed. Instead of a blank form, we present them the opportunity to revise. And they do it remotely on their time. So we are respecting them by being truly prepared when they come to the office.
The second piece of the improvement is around the, "You never remember who I am" problem, where they have been to a doctor and get the blank clipboard to fill out. Regardless of whether they were there yesterday or go to a new doctor, they get the same blank clipboard to fill out.

The other side of “never remembering who I am” is proper authentication of digital identity. It’s not just attaching a name with the face virtually. You have to be able to authenticate so that information can be shared with the patient at home. It means being able to have digital interactions that are not superficial. 

The third piece [of our patient experience improvement drive] is the online payment portal for which we use HealthPay24. The vision is not only for patients to be able to pay one bill, but for any party that has a responsibility within the healthcare system -- whether it’s a lab, ambulance, hospital or physician – to provide the capability to all be paid in a single transaction using our digital tools. We take it one step further by giving it a retail experience, with such features as “save the card on file” so if you paid the bill last week you shouldn’t have to rekey those digits into the system. 

We plan to take it even further. For example, providing more options to pay -- whether by a loan, payment plan, or to use such services as Apple Pay and Google Pay. We believe these should be stable stakes, but we’re behind and are putting in those pieces now just to catch up. 

Our longer-term vision goes far deeper. We expect to go all the way back to the point of when patients are just beginning to seek care. How do I help them understand what their financial responsibility and options are at that point, before they even have a bill in our system? This is the early version of digital transformation.

Champion patient loyalty

Gerdeman: Everything Laura just talked about comes down to one word -- loyalty. What they are putting in place will drive patient loyalty, just like consumer loyalty. In the retail space we have seen loyalty to certain brands because of how consumers interact with them, as an emotional experience. It comes down to a combination of human elements and technology to create the raving fans, in this case, of Northwell Health.

Gardner: We have seen the digital user experience approach be very powerful in other industries. For example, when I go to my bank digitally I can see all my transactions. I know what my balances are. I can set payment schedules. If I go to my investment organization, I can see the same thing with my retirement funds. If I go to my mortgage holder, same thing. I can see what I owe on my house, and maybe I want a second property and so I can immediately initiate a new loan. It’s all there. We know that this can be done.

Julie, what needs to happen to get that same level of digital transparency and give the power to the consumer to make good choices across the healthcare sector?

Rx: Tech for improved healthcare

Gerdeman: It requires a forward-looking view into what’s possible. And we’re seeing disruption. At the recent HiMSS 2019 conference [in February in Orlando] a gathering of 45,000 people were thinking like champions of healthcare -- about what can be done and what’s possible. To me, that’s where you start. 

Like Laura said, many are playing catch-up. But we also need to be leapfrogging into the future. What emerging technologies can change the dynamic? Artificial intelligence (AI) and what’s happening there, for example. How can we better leverage predictive analytics? We’re also examining Blockchain, so what can distributed ledger do and what role can it play?

I’m really excited about what’s possible with marrying emerging technology, while still solving the nuts and bolts of interoperability and integration. There is hard work in integration and interoperability to get systems talking to one another. You can’t get away from that ugly part of the job, but then there is an exciting future part of job that I think is fundamental. 


Laura also talked about culture and cultural shift. None of it can happen without an embrace of change management. That’s also hard because there are always people and personalities. But if you can embrace change management along with the technology disruption, new things can happen.

Semlies: Julie mentioned the hard, dirty work behind the scenes. That data work is really fundamental, and that has prevented healthcare from becoming more digital. People are represented by their data in the digital space. You only know people when you understand their data.

In healthcare -- at least from a provider perspective -- we have been pretty good about collecting information about a patient’s clinical record. We understand them clinically.

We also do a pretty decent job at understanding the patient from a reimbursement and charges perspective. We can get a bill out the door and get the bill paid. Sometimes if we don’t get the bill paid, when it gets down to the secondary responsibility, we do collect that information and we get those bills out. The interaction is there. 

What we don’t do well is managing processes across hundreds of systems. There are hundreds of systems in any big healthcare system today. The bridges and connections between those data systems are just not there. So a patient often finds themselves interacting with each and every one of them.

For example, I am a patient as the mom of three kids. I am a patient as the daughter of two aging parents. I am wife to a husband who I am interacting with. And I am myself my own patient. The data that I need to deal with -- and the systems I need to interact with -- when I am booking an appointment, versus paying a bill, versus looking for lab results, versus trying to look for a growth chart on a child -- I am left to self-navigate across this world. It’s very complex and I don’t understand it as a patient. 

Our job is to figure out how to manage tomorrow and the patient of tomorrow who wants to interact digitally. We have to be able to integrate all of these different data points and make that universally accessible.

Electronic medical record (EMR) portals deal more with the clinical interactions. Some have gotten good at doing some of the administrative components, but certainly not all of them. We need to create something that is far broader and has the capability to connect the data points that live in silos today -- both operationally as well as technically. This has to be the mandate.

Open the digital front door

Gardner: You don’t necessarily build trust when you are asking the patient to be the middleware, to be the sneaker-ware, walking between the PC and the mainframe. 

Let’s talk about some examples. In order to get cultural change, one of the tried-and-true methods is to show initial progress, have a success story that you can champion. That then leads to wider adoption, and so forth. What is Northwell Health’s Digital Front Door Team? That seems an example of something that works and could be a harbinger of a larger cultural shift.

Semlies: Our Digital Front Door Team is responsible for creating tools and technology to provide a single access point for our patients. They won’t have to have multiple passwords or multiple journeys in order to interact with us.

Over the course of the last year, we've established a digital platform that all of our digital technologies and personnel connect to. That last point is really important because when a patient interacts with you digitally, there is a core expectation today that if they have told you something digitally, as soon as they show up in person, you are going to know it, use it, and remember it. The technology needs to extend the conversation or journey of experience as opposed to starting over. That was really critical for our platform to provide.
When a patient interacts with you digitally, there is a core expectation today that if they have told you something digitally, as soon as they show up, you are going to know it and use it. The technology needs to extend the conversation.

Such a platform should consist of a single sign-on (SSO) capability, an API management tool, and a customer relationship management (CRM) database, from which we can learn all of the information about a patient. The CRM data drives different kinds of experiences that can be personalized and curated, and that data lives in the middle of the two data topics we discussed earlier. We collect that data today, and the CRM tool brokers all of this so it can be in the hands of every employee in the health system. 

The last piece was to put meaningful tools around the friction points we talked about, such as for appointment management. We can see availability of a provider and book directly into it with no middleman. This is direct booking, just like when I book an appointment on OpenTable. No one has to call me back. They may just send a digital reminder.

Gardner: And how has the Digital Front Door Team worked out? Do you have any metrics of success?

Good for patients, good for providers

Semlies: We took an agile approach to implementing it. Our first component was putting in the online payment capability with HealthPay24 in July 2018. Since then, we have approximately $25 million collected. In just the last six months, there have been more than 46,000 transactions. In December, we began a sign-in benefit so patients can login and see all of their balances across Northwell. 

We had 3,000 people sign-in to that process in the first several weeks, and we’re seeing evidence that our collections are starting to go up.

We implemented our digital forms tool in September 2018. We collected more than 14,000 digital forms in the first few months. Patients are loving that capability. The next version will be an at-home version so you will get text messages saying, “We see you have booked an appointment. Here are your forms to prepare for your visit.” They can get them all online. 

We are also piloting biometrics so that when you first show up at your appointment you will have the opportunity to have your picture taken. It’s iris-scanning and deep facial recognition technology so that will be the method of authentication. That will also be used more over time for self check-ins and eventually to access the ultimate portal. 

The intent was to deploy as early as there was value to the patient. Then over time all of those services will be connected as a single experience. Next to come are improved appointment management with the capability to book appointments online, as well as to change, manage, see all appointments via a connection to the patient portal.

All of those connection points will be rendered through the same single sign-in by the end of this quarter, both on our website, https://www.northwell.edu/, and via a proprietary mobile app that will come out in the app stores.

Gardner: Those metrics and rapid adoption show that a good patient experience isn’t just good for the patient -- it’s good for the provider and across the entire process. Julie, is Northwell Health unique in providing the digital front door approach?

Gerdeman: We are seeing more healthcare providers adopt this approach, with one point of access into their systems, whether you are finding a doctor or paying a bill. We have seen in our studies that seven out 10 patients only go to a provider’s website to pay a bill. 

From a financial perspective, we are working hard with leaders like Laura whose new roles support the digital patient experience. Creating that experience drives adoption, and that adoption drives improved collections.

Ease-of-use entertains and retains clients

Semlies: This channel is extremely important to us from a patient loyalty and retention perspective. It’s our opportunity to say, “We have heard you. We have an obligation to provide you tools that are convenient, easy to use, and, quite frankly, delight you.”

But the portal is not the only channel. We recognize that we have to be in lots of different places from the adoption perspective. The portal is not the only place every patient is going. There will be opportunities for us to populate what I refer to as the book-now button. And the book-now button cannot be exclusive to the Northwell digital front door.

I need to have that book-now button in the hands of every payer agent who is on the phone talking to a patient or in their digital channel or membership. I need to have it out in the Zocdocs of the world, and in any other open scheduling application out there. 

I need to have ratings and reviews. We need to be multichannel in our funnel in, but once we get you in we have to give you tools and resources that surprise and delight you and make that re-engagement with somebody else harder because we make it so easy for you to use our health system. 

And we have to be portable so you can take it with you if you need to go somewhere. The concept is that we have to be full service, and we want to give you all of the tools so you can be happy about the service you are getting -- not just the clinical outcome but the administrative service, too.

Gardner: It certainly sounds like Northwell is significantly differentiating itself with this customer-centric focus. It’s likely that as experiences improve, patients will vote with their spend across their healthcare provider choices. This will then further instigate more change in the culture and the overall adoption of improved best practices for patient well-being and satisfaction. 

I’m afraid we’ll have to leave it there. You have been listening to a sponsored BriefingsDirect healthcare insights discussion exploring the shift medical services providers are making to improve the overall patient experience in the healthcare sector.


And we have learned how improving patient experiences will increasingly rely on the many tools available to other types of businesses.

Our next extreme use-case for high-performance computing (HPC) examines how the strictly governed redesign of Formula 1 race cars relies on data center innovation to coax out the best in fluid dynamics analysis and refinement.

We’ll now hear how Alfa Romeo Racing (formerly Alfa Romeo Sauber F1 Team) in Hinwil, Switzerland leverages the latest in IT to bring hard-to-find but momentous design improvements -- from simulation, to wind tunnel, to test track, and ultimately, to victory. The goal: To produce cars that are glued to the asphalt and best slice through the air.

Here to describe the challenges and solutions from the compute-intensive design of Formula 1 cars is Francesco Del Citto, Head of Computational Fluid Dynamics Methodology for Alfa Romeo Racing. Welcome, Francesco.


Del Citto: Hello and thank you.

Gardner: We are also here with Peter Widmer, Worldwide Category Manager for Moonshot/Edgeline and Internet of Things (IoT) at Hewlett Packard Enterprise (HPE). Welcome, Peter.

Widmer: Thank you.

Gardner: Why does Alfa Romeo Racing need to prepare for another car design again?

Del Citto
Del Citto: Effectively, it’s a continuous design process. We never stop, especially on the aerodynamic side. And what every Formula 1 team does is dictated by each race season and by the specific planning and concept of your car in terms of performance.

For Formula 1 racing, the most important and discriminating factor in terms of performance is aerodynamics. Every Formula 1 team puts a lot of effort in designing the aerodynamic shape of their cars. That includes for brake cooling, engine cooling, and everything else. So all the airflow around and inside of the car is meticulously simulated to extract the maximum performance.

Gardner: This therefore becomes as much an engineering competition as it is a racing competition.

Engineered to race

Del Citto: Actually, it’s both. On the track, it’s clearly a racing competition between drivers and teams. But before you ever get to the track, it is an engineering competition in which the engineers both design the cars as well as the methods used to design the cars. Each Formula 1 team has its own closely guarded methodologies and processes – and they are each unique.

Gardner: When I first heard about fluid dynamics and aerodynamic optimization for cars, I was thinking primarily about reduction of friction. But this is about a lot more, such as the cooling but also making the car behave like a reverse airplane wing.

Tell us why the aerodynamic impacts are much more complicated than people might have appreciated.

Del Citto: It is very complicated. Most of the speed and lap-time reductions you gain are not on the straightaways. You gain over your competitors in how the car behaves in the corners. If you can increase the force of the air acting on the car -- to push the car down onto the ground -- then you have more force preventing the car from moving out of line in the corners.

Why use the force of the air? Because it is free. It doesn’t come with any extra weight. But it is difficult to gain such extra inertial control forces. You must generate them in an efficient way, without being penalized too much from friction.

It’s also difficult to generate such forces without breaking the rules, because there are rules. There are limits for designing the shapes of the car. You cannot do whatever you want. Still, within these rules, you have to try to extract the maximum benefits.

The force the car generates is called downforce, which is the opposite of lift force from the design of an airplane. The airplane has wings designed to lift. The racing car is designed to be pushed down to the ground. The more you can push to the ground, the more grip you have between the tires and the asphalt and the faster you can go in the corners before the friction gives up and you just slide.

Gardner: And how fast do these cars go nowadays?

Del Citto: They are very fast on the straight, around 360-370 km/hour (224-230 mph), especially in Mexico City, where the air is thin due to the altitude. You have less resistance and they have a very long straight there, so this is where you get the maximum speeds.

But what is really impressive is the corner speed. In the corners you can now have a side acceleration force that is four to five times the force of gravity. It’s like being in a jet fighter plane. It’s really, really high.

Widmer
Widmer: They wear their security belts not only to hold them in in case of an accident, but also for when they brake and steer. Otherwise, they could be catapulted out of the car because the forces are close to 5G. The efficiency of the car is really impressive, not only from the acceleration or high speeds. The other invisible forces also differentiate a Formula 1 car from a street car.

Gardner: Peter, because this is an engineering competition, we know the simulations result in impactful improvements. And that then falls back on the performance of the data center and its level of innovation. Why is the high-performance computing environment such an essential part of the Formula 1 team?

Widmer: Finding tens of thousands of a second on the racetrack, where a lap time can be one minute or less, pushes the design of the cars to the extreme edge. To find that best design solution requires computer-aided design (CAD) guidance -- and that’s where the data center plays an important part.

Those computational fluid dynamics (CFD) simulations take place in the data center. That’s why we are so happy to work together with Alfa Romeo Racing as a technology partner.

Gardner: Francesco, do you have constraints on what you can do with the computers as well as what you can do with the cars?

Limits to compute for cars

Del Citto: Yes, there are limits in all aspect of the car, design, and especially in the aerodynamic research. That’s because aerodynamics is where you can extract more performance -- but it’s where you can spend more money as well.

The Formula 1 governing body, the FIA, a few years ago put in place ways of controlling the money spent for aerodynamic research. So instead of putting on a budget cap, they decided to put a limit on the resources you can use. The resources are both the wind tunnel and the computational fluid dynamics. It’s a tradeoff between the two. The more wind tunnel you use, the less computational power you can use, and vice versa. So each team has its sweet spot, depending on their strategy.

You have restrictions in how much computational capacity you can use to solve your simulations. You can do a lot of post-processing and pre-processing, but you cannot extract too much from that. The solving part, in which it tells you the performance results of the new car design, is what is limited.

Gardner: Peter, how does that translate into an HPE HPC equation? How do you continuously innovate to get the most from the data center, but without breaking the rules?

Widmer: We work with a competency center on the HPC to determine the right combination of CPU, throughput, and whatever it takes to get the end results, which are limited by the regulations.

We are very open on the platform requirements for not only Alfa Romeo Racing, but for all of the teams, and that’s based on the most efficient combination of CPU, memory, networking, and other infrastructure so that we can offer the CFD use-case.

It takes know-how about how to tune the CPUs, about the specifics of the CFD applications, and knowledge of the regulations formula which then leads us to get that success in CFD for Formula 1.

Gardner: Let’s hear more about that recipe for success.

Memory makes the difference

Widmer: It’s an Intel Skylake CPU, which includes graphic cards onboard. That obviously is not used for the CFD use-case, but the memory we do use as a level-four memory cache. That then provides us extra performance, which is not coming from the CPU, which is regulated. Due to the high-density packaging of the HPE Moonshot solution -- where we can put 45 compute notes in a 4.30 rack chassis -- this is quite compact. And it’s just topped out at about 5,000-plus cores.

Del Citto: Yes, 5,760 cores. As Peter was saying before, the key factor here is the software. There are three main CFD software applications used by all the Formula 1 teams.

The main limitation for this kind of software is always the memory bandwidth, not the computational power. It’s not about the clock speed frequency. The main limitation is the memory bandwidth. This is why the four-level cache gives the extra performance, even compared to a higher spec Intel server CPU. The lower spec with low energy use CPU version gives us the extra performance we need because of the extra memory cache.

Gardner: And this isn’t some workload you can get off of a public cloud. You need to have this on-premises?

Del Citto: That’s right. The HPC facility is completely owned and run by us for the Formula 1 team. It’s used for research and even for track analysis data. We use it for multiple purposes, but it’s fully dedicated to the team.

It is not in the cloud. We have designed a building where we have a lot of electricity and cooling capacity requirements. Consider that the wind tunnel fan -- only the fan – uses 3 megawatts. We need to have a lot of electricity there.

Gardner: Do you use the wind tunnel to cool the data center?

Del Citto: Sort of. We use the same water to cool the wind tunnel and the data center. But the wind tunnel has to be cooled because you need the air at a constant temperature to have consistent tests.

Gardner: And Peter, this configuration that HPE has put together isn’t just a one-off. You’re providing the basic Moonshot design for other Formula 1 teams as well?

A winning platform

Widmer: Yes, the solution and fit-for-regulations design was so compelling that we managed to get 6 out of 10 teams to use the platform. We can say that at least the first three teams are on our customer list. Maybe the other ones will come to us as well, but who knows?

We are proud that we can deliver a platform to a sport known for such heavy competition and that is very technology-oriented. It’s not comparable to any other sport because you must consistently evolve, develop, and build new stuff. The evolution never stops in Formula 1 racing.

For a vendor like HPE, it’s really a very nice environment. If they have a new idea that can give a team a small competitive advantage, we can help them do it. And that’s been the case for 10 years now.

Let’s figure out how much faster we can go, and then let’s go for it. These teams are literally open-minded to new solutions, and they are eager to learn about what’s coming down the street in technology and how could we get some benefits out of it. So that’s really the nice story around it.

Gardner: Francesco, you mentioned this is a continuous journey. You are always looking for new improvements, and always redesigning.

Now that you have a sophisticated HPC environment for CFD and simulations, what about taking advantage of HPC data center for data analysis? For using artificial intelligence (AI) and machine learning (ML)?

Is that the next stage you can go to with these powerful applications? Do you further combine the data analysis and CFD to push the performance needle even further?

Del Citto: We generate tons of data -- from experiments, the wind tunnel, the CFD side, and from the track. The cars are full of sensors. During a practice run, there are hundreds of pressure sensors around the car. In the wind tunnel, there are 700 sensors constantly running. So, as you can imagine, we have accumulated a lot of data.

Now, the natural step will be how we can use it. Yes, this is something everyone is considering. I don’t know where this will bring us. There is nothing else I can comment on at the moment.

Gardner: If they can put rules around the extent to which you can use a data center for AI, for example, it could be very powerful.

Del Citto: It could be very powerful, yes. You are suggesting something to the rule-makers now. Obviously, we have to work with what we have now and see what will come next. We don’t know yet, but this is something we are keeping our eyes on, yes.
