Emerging technologies in biomechanics offer huge promise for the workers’ compensation world.

Take the Motus Pro: a multi-sensor training tool that tracks the throwing and batting movements of baseball players, particularly those who are rehabilitating from injuries.

Developed by the Massapequa, N.Y.-based biomechanics software and analytics firm Motus, the sensor provides feedback to baseball teams’ medical staff to aid in their return-to-play programs.

But the firm has always set its sights beyond baseball, developing its physics engine, hardware and training tools in a manner that would allow the firm to eventually address the larger population beyond athletes, said co-founder and chief executive Joe Nolan.

“We are starting to work on early projects with partners outside the world of sports to refine applications that can be applied to worker safety, human performance optimization and evidence-based, quantified-outcome physical therapy programs,” Nolan said.

There are dozens more products like the Motus Pro that could have a place in the workers’ comp industry, including some of the wearable technology currently being used in baby sensors and monitors to track fetal movement in the womb, said Zack Craft, vice president of rehab solutions, complex care education at One Call Care Management in Jacksonville, Fla.

Wearables could be used in the ergonomics space to potentially prevent carpel tunnel syndrome by monitoring the position of the elbow, total muscles used and the speed of muscles being used by employees during the workday, Craft said.

If a worker has already filed a claim for carpel tunnel, the tool could be used to monitor appropriate positioning and could validate recommendations and potential retraining by providing solid outcome data.

“The small sensor is easily attached using a plastic clip on a glove or through the use of a compression garment,” he said. “For individuals working in an office environment, a very simple postural device can really help them learn to avoid poor positions and improve their posture.”

Wearable technology also has the potential to benefit clinical studies, Craft said. An example is the impact wearables can have on paraplegic patients in the prevention of shoulder injuries such as rotator cuff damage.

Sensors could be used to evaluate the movements of paraplegics in wheelchairs to determine whether they are properly forming a full propelling stroke to avoid damage to their wrist or shoulders.

“This data could then be collected and used to educate the injured worker and any caretakers to prevent the development of bad habits, or to help them relearn appropriate movements,” he said.

“Prevention of these types of injuries is key for paraplegics since the use of their shoulders is critical to complete transfers and pressure shifts.”

Apple recently announced an enhancement to its new Health app to assist wheelchair users in tracking their wheelchair propelling strokes as well calorie burn, periodically reminding them to stay active and take a “roll” around the block, Craft said.

“Wouldn’t it be great if we were able to get an injured worker in physical therapy to upload their exercise information to their workers’ comp treating doctor and claims manager, to see if they were meeting their daily goals?” — Dr. Teresa Bartlett, SVP, medical quality, Sedgwick Claims Management Services

Kathryn L. Havens, assistant professor of clinical physical therapy at the University of Southern California’s Division of Biokinesiology and Physical Therapy in Los Angeles, said that sensors have many great applications, but the difficulty is processing and interpreting all of the data.

Havens has had many discussions with other biomechanists about how to detect certain movement patterns from these velocities and accelerations, because the output from sensors “isn’t so straightforward.”

“I think there is potential and engineers are developing better algorithms for this,” she said. “But at this point we still need trained movement scientists to analyze the data from these sensors in order for the data to be useful.”

Dr. Teresa Bartlett, senior vice president, medical quality at Sedgwick Claims Management Services Inc., believes that technology will eventually be interspersed throughout all of medicine.

“In fact, I am looking for a client that wants to engage some wearable technology in a workers’ comp setting,” Bartlett said. “There are large manufacturers that could benefit from a health and safety perspective.”

Preventing Claims

Bartlett believes there is a place for such emerging technologies in a manufacturing setting to help prevent worker injuries. For example, sensors could be used by people to prevent elbow and shoulder injuries, to understand mechanics, thrust and the amount of energy it takes to perform certain jobs.

Moreover, existing technologies like the Apple Watch or Fitbit could help mitigate low back strain by getting workers to walk more during the day, Bartlett said.

“Wouldn’t it be great if we were able to get an injured worker in physical therapy to upload their exercise information to their workers’ comp treating doctor and claims manager, to see if they were meeting their daily goals?”

It would also help practitioners better understand if injured workers are being compliant with the quality of their exercise programs and to understand duration and intervals, she said.

For example, practitioners could determine whether workers are walking only in small increments such as one-minute intervals to the bathroom, whether they are walking five miles in one exercise period, or whether they’re walking five miles in one-mile increments.

“This information could make a big difference in their treatment plan and discussion with their doctor or nurse case manager,” Bartlett said.

High ROI on Publicly Funded Stay at Work Programs

Governments as well as employers stand to benefit significantly by investing in programs that keep employees at work after an illness or injury.

Publicly funded stay-at-work/return-to-work programs could help employers that may face reduced productivity from injured workers returning before they are at 100 percent of functionality, suggests a new report.

State and/or federally funded SAW/RTW programs could also save the governments themselves unnecessary expenses for injured workers who are laid off or cannot return to their jobs. While the authors focus on employees not covered by workers’ comp programs, the case can also be made for covered workers who do not receive the help they should.

“Despite the clear benefits to workers and taxpayers, no federal agency is in charge of preventing job loss after injury or illness.”

“Millions of hard-working Americans leave the labor force every year, at least temporarily, because of injury or illness. Without steady earnings, these workers and their families often end up in public programs such as Social Security Disability Insurance, Supplemental Security Income, Medicare, and Medicaid. The resulting costs to state and federal governments are steep,” the report begins.

“But the public sector could help to reduce those costs by adopting strategies to help people stay at or return to work, rather than fall through the cracks of a fragmented system.”

The brief, The Case for Public Investment in Stay-at-Work/Return-to-Work Programs, was developed for the SAW/RTW Policy Collaborative, housed in the Department of Labor’s Office of Disability Employment Policy. The document is part of the collaborative’s efforts to promote positive SAW/RTW programs.

“Despite the clear benefits to workers and taxpayers, no federal agency is in charge of preventing job loss after injury or illness. And state workforce and vocational rehabilitation agencies have not traditionally focused on workers who are at risk of losing their jobs because of injury or illness,” the brief states.

“State-regulated workers’ compensation systems provide cash and medical benefits to workers who experience work-related injury or illness. But they do not help the millions of employees whose medical conditions are not work related, and they often fail to help even those who are covered.”

The Costs

The authors looked at the costs and benefits of an early intervention SAW/RTW program at the state level. They compared the costs to state and federal governments, the injured worker, and employers for a worker returning after an injury in a state with a hypothetical SAW/RTW program to one with no such program.

“Under our baseline assumptions, the state government would save about $83,000 in net benefits for each worker who is retained rather than replaced, following the onset of long-term disability,” the report says. “About $71,000 (or 85 percent) of the net benefits to the state would come from higher tax revenues under the SAW/RTW scenario than under the no-SAW/RTW scenario. The rest would predominantly be a result of avoiding the costs of Medicaid and unemployment compensation.”

Such a program would save the federal government even more — an estimated $292,000 in net benefits until the worker’s retirement. Much of those costs would result from avoiding public assistance expenses with the rest from higher tax revenues. The injured worker under the scenario would gain about $422,000 in net benefits from keeping his job and the associated compensation.

“The state government would save about $83,000 in net benefits for each worker who is retained rather than replaced, following the onset of long-term disability.”

Retaining an injured worker would admittedly be an expense for the employer. While the costs of recruiting, hiring, and training a new employee would be eliminated, the anticipated loss of productivity for an injured worker at less than full capacity equates to an estimated $185,000 — mainly from the assumed 16.3 percent reduction in productivity. However, those costs could be lowered.

“States may need to make larger investments, including subsidizing the wages of those with greatly reduced productivity, to sharply increase the number of workers who stay in the labor force,” the report says. “But states may not be willing to make these investments unless the federal government or workers (possibly via a payroll tax) help pay for them.”

Government Tools

States already have a variety of ways in which to help foster SAW/RTW efforts. “The workers’ comp system can make regulatory, process or service changes to improve the SAW/RTW services for workers with job related conditions,” according to the collaborative. “Some states have reemployment subsidies until the workers return to 100 percent functional capacity.”

State governments can include aggressive SAW/RTW strategies in their Workforce Innovation and Opportunity Act plan. The act, implemented last summer, requires states to strategically align their workforce development programs.

Workforce agencies can help employees and employers identify and access SAW/RTW services, support development of, and state agency cooperation with, employment resource networks that facilitate SAW/RTW support, and leverage capabilities developed under the state’s Disability Employment Initiative.

Several states have tools in their short-term disability programs that allow wage subsidies or partial benefits for RTW. And state personnel agencies can help state workers by improving their access to evidence-based SAW/RTW services and improving incentives for workers and their managers to use SAW/RTW services effectively.

Washington State’s Model

A unique program in Washington State pays employers to help injured workers stay on the job. Stay at Work “is a financial incentive that encourages employers to bring their injured workers quickly and safely back to light duty or transitional work by reimbursing them for some of their costs,” the Washington State Department of Labor and Industries website states.

Employers may be reimbursed for 50 percent of the base wages paid to injured workers, as well as some of the costs of training, tools, or clothing the worker needs to undertake the transitional or light-duty work.

The program “has increased return to work and reduced workers’ compensation costs,” according to the SAW/RTW Policy Collaborative.

Commercial Auto Warning: Emerging Frequency and Severity Trends Threaten Policyholders

Commercial auto policyholders should consider utilizing a consultative approach and tools to better manage their transportation exposures.
By: | June 1, 2016 • 6 min read

The slow but steady climb out of the Great Recession means businesses can finally transition out of survival mode and set their sights on growth and expansion.

The construction, retail and energy sectors in particular are enjoying an influx of business — but getting back on their feet doesn’t come free of challenges.

Increasingly, expensive commercial auto losses hamper the upward trend. From 2012 to 2015, auto loss costs increased a cumulative 20 percent, according to the Insurance Services Office.

“Since the recession ended, commercial auto losses have challenged businesses trying to grow,” said David Blessing, SVP and Chief Underwriting Officer for National Insurance Casualty at Liberty Mutual Insurance. “As the economy improves and businesses expand, it means there are more vehicles on the road covering more miles. That is pushing up the frequency of auto accidents.”

For companies with transportation exposure, costly auto losses can hinder continued growth. Buyers who partner closely with their insurance brokers and carriers to understand these risks – and the consultative support and tools available to manage them – are better positioned to protect their employees, fleets, and businesses.

Liberty Mutual’s David Blessing discusses key challenges in the commercial auto market.

More Accidents, More Dollars

Rising claims costs typically stem from either increased frequency or severity — but in the case of commercial auto, it’s both. This presents risk managers with the unique challenge of blunting a double-edged sword.

Cumulative miles driven in February, 2016, were up 5.6 percent compared to February, 2015, Blessing said. Unfortunately, inexperienced drivers are at the helm for a good portion of those miles.

A severe shortage of experienced commercial drivers — nearing 50,000 by the end of 2015, according to the American Trucking Association — means a limited pool to choose from. Drivers completing unfamiliar routes or lacking practice behind the wheel translate into more accidents, but companies facing intense competition for experienced drivers with good driving records may be tempted to let risk management best practices slip, like proper driver screening and training.

Distracted driving, whether it’s as a result of using a phone, eating, or reading directions, is another factor contributing to the number of accidents on the road. Recent findings from the National Safety Council indicate that as much as 27% of crashes involved drivers talking or texting on cell phones.

The factors driving increased frequency in the commercial auto market.

In addition to increased frequency, a variety of other factors are driving up claim severity, resulting in higher payments for both bodily injury and property damage.

Treating those injured in a commercial auto accident is more expensive than ever as medical costs rise at a faster rate than the overall Consumer Price Index.

“Medical inflation continues to go up by about three percent, whereas the core CPI is closer to two percent,” Blessing said.

Changing physical medicine fee schedules in some states also drive up commercial auto claim costs. California, for example, increased the cost of physical medicine by 38 percent over the past two years and will increase it by a total of 64 percent by the end of 2017.

And then there is the cost of repairing and replacing damaged vehicles.

“There are a lot of new vehicles on the road, and those cost more to repair and replace,” Blessing said. “In the last few years, heavy truck sales have increased at double digit rates — 15 percent in 2014, followed by an additional 11 percent in 2015.”

The impact is seen in the industry-wide combined ratio for commercial auto coverage, which per Conning, increased from 103 in 2014 to 105 for 2015, and is forecast to grow to nearly 110 by 2018.

None of these trends show signs of slowing or reversing, especially as the advent of driverless technology introduces its own risks and makes new vehicles all the more valuable. Now is the time to reign in auto exposure, before the cost of claims balloons even further.

The factors driving up commercial auto claims severity.

Data Opens Window to Driver Behavior

To better manage the total cost of commercial auto insurance, Blessing believes risk management should focus on the driver, not just the vehicle. In this journey, fleet telematics data plays a key role, unlocking insight on the driver behavior that contributes to accidents.

“Roughly half of large fleets have telematics built into their trucks,” Blessing said. “Traditionally, they are used to improve business performance by managing maintenance and routing to better control fuel costs. But we see opportunity there to improve driver performance, and so do risk managers.”

Liberty Mutual’s Managing Vital Driver Performance tool helps clients parse through data provided by telematics vendors and apply it toward cultivating safer driving habits.

“Risk managers can get overwhelmed with all of the data coming out of telematics. They may not know how to set the right parameters, or they get too many alerts from the provider,” Blessing said.

“We can help take that data and turn it into a concrete plan of action the customer can use to build a better risk management program by monitoring driver behavior, identifying the root causes of poor driving performance and developing training and other approaches to improve performance.”

Actions risk managers can take to better manage commercial auto frequency and severity trends.

Rather than focusing on the vehicle, the Managing Vital Driver Performance tool focuses on the driver, looking for indicators of aggressive driving that may lead to accidents, such as speeding, sharp turns and hard or sudden braking.

The tool helps a risk manager see if drivers consistently exhibit any of these behaviors, and take actions to improve driving performance before an accident happens. Liberty’s risk control consultants can also interview drivers to drill deeper into the data and find out what causes those behaviors in the first place.

Sometimes patterns of unsafe driving reveal issues at the management level.

“Our behavior-based program is also for supervisors and managers, not just drivers,” Blessing said. “This is where we help them set the tone and expectations with their drivers.”

For example, if data analysis and interviews reveal that fatigue factors into poor driving performance, management can identify ways to address that fatigue, including changing assigned work levels and requirements.  Are drivers expected to make too many deliveries in a single shift, or are they required to interact with dispatch while driving?

“Management support of safety is so important, and work levels and expectations should be realistic,” Blessing said.

A Consultative Approach

In addition to its Managing Vital Driver Performance tool, Liberty’s team of risk control consultants helps commercial auto policyholders establish screening criteria for new drivers, creating a “driver scorecard” to reflect a potential new hire’s driving record, any Motor Vehicle Reports, years of experience, and familiarity with the type of vehicle that a company uses.

“Our whole approach is consultative,” Blessing said. “We probe and listen and try to understand a client’s strengths and challenges, and then make recommendations to help them establish the best practices they need.”

“With our approach and tools, we do something no one else in the industry does, which is perform the root cause analysis to help prevent accidents, better protecting a commercial auto policyholder’s employees and bottom line.”
