Nursing faculty and students leverage advancements in computing and data to move the field forward

By Daniel Robison

As a nurse, Megan Foradori, RN, tried to make sure no child in need of developmental support fell through the cracks.

Across pediatric nursing roles in multiple states, she saw firsthand how babies and toddlers are screened for crucial social, speech and developmental milestones鈥攁nd fiercely advocated for services for children who scored poorly.

鈥淭hese services can transform their futures鈥攅specially at key periods of brain and physical growth,鈥� said Foradori, a PhD candidate at Case Western Reserve University Frances Payne Bolton School of Nursing. 鈥淏ut I also saw service providers stretched too thin and doctors hesitating to deliver potentially distressing news to parents鈥攊nstead hoping the child might outgrow the issue.鈥�

The experiences inspired Foradori to focus her PhD thesis to better identify patterns on which children are screened and receive services鈥攁nd determine who is being missed along the way. She is using machine learning algorithms鈥攁 form of artificial intelligence (AI)鈥攖o analyze large datasets, including the National Survey of Children鈥檚 Health from the U.S. Health Resources and Services Administration.

鈥淓ach child in the data has a unique constellation of characteristics,鈥� said Foradori.

鈥淢achine learning helps us drill down and see drivers of outcomes we couldn鈥檛 have seen ourselves because of the sheer volume of data and the complexity of each child.鈥�

From her research, Foradori is aiming to create new clinical guidance to help more children receive key interventions鈥攕uch as speech and behavioral therapy鈥攂efore entering kindergarten, which research shows can significantly improve their long-term development.

鈥淢y personal experiences as a nurse showed me the realities of how kids can get left behind,鈥� she said. 鈥淣ow as a researcher, I can pair my nursing background with deep data analysis to find ways to help children when they need it the most.鈥�

On the cusp

Like Foradori, several faculty members and graduate students at the nursing school are using AI-related approaches in research, practice and education.

Their applications of the technology have the potential to improve many aspects of healthcare鈥攁ccelerating scientific discovery, helping physicians and nurses make better decisions, improving medical advice for patients and reducing the burden of paperwork.

鈥淭hese are not necessarily new research methods or forms of statistical analysis,鈥� said Andrew Reimer, PhD, RN (NUR 鈥�04; GRS 鈥�10, nursing), associate professor of nursing. 鈥淏ut now we have the computing ability to handle larger datasets and come to deeper levels of comprehension.鈥�

In recent years, Case Western Reserve has created a high-performance computing cluster鈥攁vailable to researchers across the university鈥攖hat allows for computationally intensive research using advanced servers, processors and software systems. This formidable resource enables faculty to tackle large-scale, data-intensive problems and run complex simulations and analyses more efficiently and accurately than before.

鈥淚t鈥檚 a powerful system allowing us to examine every possible combination of variables, leading to more thorough understanding of research questions鈥攁nd helping us arrive at more accurate results,鈥� said Ron Hickman Jr., PhD, RN (CWR 鈥�00; NUR 鈥�02, 鈥�06, 鈥�13; GRS 鈥�08, nursing), associate dean for research at the nursing school.

The university鈥檚 computing cluster has accelerated AI-related activity at the nursing school, leading to an array of projects that highlight both the immense opportunities and the challenges of integrating AI into healthcare discovery and practice.

鈥淥ur research is right there on the cusp of realizing what鈥檚 possible using AI to improve health,鈥� said Hickman.

Rural health realities

Imagine someone in rural Ohio suffers a heart attack. The response involves multiple steps鈥攃alling 911, dispatching local emergency services and transferring the patient to a hospital鈥攁nd often depends on a helicopter transporting the patient to an urban medical facility.

鈥淓specially when dealing with these critical conditions, every minute counts,鈥� said Reimer. 鈥淪till, there are many patients moved by medical transport who don鈥檛 benefit at all.鈥�

One in five Americans live in rural areas, which make up nearly 97% of the country鈥檚 land. This distribution creates challenges for accessing healthcare services鈥攑articularly in emergencies鈥攁nd helps explain why rural patients have the worst outcomes of any broad geographic group in the top five leading causes of death, including strokes and traumatic injuries.

Reimer is aiming to better predict transport outcomes to determine which patients should be transferred and when. Using machine learning, he鈥檚 integrating disparate datasets鈥攅lectronic health records (EHRs), transport information, social determinants of health and other variables鈥攊nto a new platform that pinpoints the factors affecting care and so-called 鈥渢ransport deserts,鈥� where access is limited.

For one, data for studying the issue comes from many separate sources and serves different purposes. Each captures an aspect of the continuum of care, such as a patient鈥檚 home location, municipality data on their emergency response services and closest medical helicopters.

鈥淏y layering data in new ways and fusing them together from a geographic perspective,鈥� said Reimer, 鈥渨e create a more complete picture of what鈥檚 happening鈥攁nd how we can optimize patient transport decisions, especially when time is of the essence.鈥�

The research is informing Reimer鈥檚 efforts to develop a clinical tool to help align the care appropriate for each patient鈥檚 condition.

鈥淭his can lead to better distribution of the very limited emergency resources that cover vast areas of our country,鈥� he said.

From data to decisions

Vast troves of patient data鈥攊ncluding EHRs鈥攃ould contain undiscovered revelations about the multifaceted nature of human health.

By analyzing EHRs with machine learning methods, nursing school researchers are exploring predictive tools that could improve the guidance providers give to patients.

To Nicholas Schiltz, PhD (GRS 鈥�13, epidemiology and biostatistics), an assistant professor at the nursing school, the possibilities have the potential to transform healthcare.

鈥淭here are AI-based models that can predict things or figure out things better than a human,鈥� said Schiltz. 鈥淎 lot of times they do outperform a clinician in certain areas, especially when there鈥檚 complexity and rarity involved.鈥�

Schiltz is studying how projecting likely patient outcomes鈥攊ncluding disease trajectories for high-risk subgroups, particularly in older adults鈥攃an identify underlying causes and facilitate early intervention strategies.

鈥淢achine learning is helping us understand optimal prevention and treatment strategies in a more nuanced way,鈥� said Schiltz. 鈥淲hen we can identify which health conditions are likely to occur next, given patients鈥� current characteristics, we can find the right course.鈥�

Schiltz, who also serves as Foradori鈥檚 advisor for her work analyzing large datasets to improve developmental support for children, has used machine learning techniques in multiple studies.

In research published in Journal of General Internal Medicine, Schiltz used Medicare claims data to identify combinations of morbidities associated with hospital readmissions. The same information also revealed that limitations in basic activities of daily living鈥攑reparing meals or housekeeping, for instance鈥攃an be used to better predict risk of re-hospitalization.

鈥淭he goal is to eventually integrate related assessments into EHRs so providers can identify at-risk patients during appointments,鈥� he said.

However, moving research to practical applications in healthcare settings can require a significant effort and expense鈥攊ncluding testing, validation and ensuring that AI tools are effective across diverse populations.

As it stands, many genomic datasets are composed mostly of white patients with Northern European ancestry, meaning AI models trained on the information can reinforce existing biases. Plus, the resulting tools may not perform effectively for other races or ethnicities.

鈥淚mplementation science is an emerging field,鈥� said Schiltz. 鈥淚t鈥檚 not enough to just make evidence鈥攚e have to consider how providers will actually use these tools on a daily basis.鈥�

Companion for caregiving

Instead of flipping through textbooks or scouring the internet for reputable information, Chitra Dorai imagined there had to be a better way for dementia caregivers to quickly get answers to their questions.

Dorai knew the experience all too well. While caring for a parent with Parkinson鈥檚 disease, she recalled feeling ill-prepared for the challenge. 鈥淚 was not alone in needing a source of support and information,鈥� she said.

Drawing on her two-plus decades as an IBM executive, Dorai founded Amicus Brain Innovations and created an AI-enhanced text messaging chatbot, named Keiko, to serve as a digital advisor for dementia caregivers.

Trained using large language models, Keiko 鈥渋nteracts in a conversational style in multiple languages and provides personalized guidance based on research,鈥� said Dorai.

Helping dementia caregivers is also a cornerstone of the work of Kylie Meyer, PhD鈥攄riven by her personal experiences. During college, she held a family intervention to discuss the dementia symptoms of a close relative, who was later diagnosed with Alzheimer鈥檚 disease and primarily cared for by a spouse.

鈥淚 got to see caregiving up close and the difficult conversations that come with it鈥攊ncluding the costs involved,鈥� said Meyer, an assistant professor at the School of Nursing.

To help reduce the nearly $470 billion annual financial burden on unpaid caregivers, as estimated by the AARP Public Policy Institute, Meyer developed an intervention called CONFIDENCE. This program, featuring online group-based learning sessions and workbook exercises, aimed to offer much-needed support. However, early users suggested that the program could benefit from being more engaging.

Enter: Keiko.

Working together, Meyer and Dorai integrated the AI-powered chatbot into CONFIDENCE. Now, they are in the midst of a clinical trial with Latino caregivers, who spend a disproportionate amount鈥攏early half (47%) of their household income鈥攐n such expenses, compared to 26% among caregivers from other ethnic backgrounds.

鈥淚f our intervention works for Latino families, then it鈥檚 on the right track for addressing these issues for caregivers in general,鈥� said Meyer.

While the program uses new technology, it鈥檚 rooted in the time-tested principle of resourcefulness鈥攁n approach that provides caregivers with the flexibility to learn and receive coaching in ways that fit their schedules and preferences.

鈥淯sing this tool to help people was a 鈥榳ow moment鈥� for me,鈥� said Meyer. 鈥淭he tech is here now鈥攏ot in some distant future.鈥�

Smart care coordination

It鈥檚 long been established that poor care coordination鈥攖ransitioning patients to the next point of treatment鈥攃an lead to negative health outcomes and an increased economic burden on patients and society.

Still, conventional approaches have changed little in response to such evidence鈥攐ften involving manually sifting through patient files and calling lists of providers to arrange transfers of care.

鈥淗aving been a nurse for many years, I鈥檝e seen the inefficiencies,鈥� said Hickman, who is also the Ruth M. Anderson Professor at the nursing school. 鈥淓specially given the high caseloads of care coordinators and frustration of patients, changes are needed.鈥�

Recently, Hickman began a collaborative effort with Ashley Barrow, an entrepreneur and former care coordinator. In 2019, she founded the startup RE-Assist and is building an AI-based tool of the same name that aims to digitize and improve care coordination.

Still in development, the cloud-based software service uses algorithms to interrogate many types of EHRs to make care recommendations to hospitals and patients. The aim is to streamline coordination between them, as well as insurance companies and providers.

鈥淚t鈥檚 not meant to replace care coordinators, but to assist them,鈥� said Hickman.

Together, he and Barrow are refining the algorithms that extract information from EHRs, while conducting simulations with anonymized patient data and gathering feedback in focus groups with patients and healthcare professionals.

It鈥檚 a lengthy process of validation that means the tool could be years away from use鈥攂ut it鈥檚 worth the investment of time, Hickman said.

鈥淎I applications like this have great potential to make us better nurses,鈥� he said. 鈥淩esearchers have a duty to lead by example鈥攁nd that means using and developing new technology carefully and responsibly.鈥�
