UNIVERSITY PARK, Pa. — Artificial intelligence (AI) may one day play a larger role in medicine than the online symptom checkers available today. But these “AI doctors” may need to get more personal than human doctors to increase patient satisfaction, according to a study led by researchers at Penn State. They found that the more social information an AI doctor recalls about patients, the higher the patients’ satisfaction, but only if they were offered privacy control.
The research team published their findings in the journal Communication Research.
“We tend to think of AI doctors as machines that are antiseptic and generic,” said S. Shyam Sundar, Evan Pugh University Professor and the James P. Jimirro Professor of Media Effects at Penn State. “What we show in this study is that it’s important for these AI systems to not just talk about a patient’s medical history but also to individuate them socially by recalling certain non-medical information about them, such as their occupation and hobbies. At the end of the day, AI doctors may guide patients through telehealth visits just as well as human doctors.”
To see whether a doctor’s knowledge of a patient’s social or medical history increases patient satisfaction, the researchers asked 382 online participants to interact with a medical chatbot over two visits spaced about two weeks apart. Participants were told that they were interacting with a human doctor, an AI doctor or an AI-assisted human doctor. During the first visit the “doctor” — in reality, a pre-compiled script that the researchers created for consistency — chatted with patients about topics related to diet, fitness, lifestyle, sleep and mental health, and asked personal information about their occupation, relationship with their family, dietary habits and favorite activities. Then the doctor offered general recommendations for diet, exercise and mental health management.
During the second visit, the doctor either recalled the patient’s medical or personal information or asked the patient to remind them of this information. Then the doctor gave similar health advice as they did in the first visit and offered half the patients the option to put their visit on the record and save their information to the online platform at the conclusion of the final session. Participants then completed an online questionnaire to assess their satisfaction with the service.
The researchers found that patients gave higher scores to AI doctors that recalled the patient’s social information as long as the doctor offered privacy control before concluding the visit. The human doctor, on the other hand, did not need to recall either social or medical information for patients to feel that they had a close relationship with the doctor.
“When an AI doctor recalls a patient’s social information, it is perceived as putting more effort into individuation, which leads to higher patient satisfaction, but only when the patient has privacy control,” said Cheng “Chris” Chen, lead author and assistant professor of communication design at Elon University who graduated from the doctoral program of mass communications at Penn State. “This was surprising because AI systems treat all data the same, but patients see it differently. They perceived it as the doctor putting in more effort to recall the patient’s social information.”
The process still requires effort on the patient’s part, Sundar added.
“Patients still want the AI system to provide them privacy control,” he said. “It’s like, as long as you give me control over my data, I appreciate you knowing about my social life and appreciate the effort you put in.”
The study has implications for the design of AI systems in the medical field, according to the researchers.
“Recalling patient social information may lead to better satisfaction and patient compliance and more positive health outcomes,” Cheng said.
According to co-author Joe Walther, Bertelsen Presidential Chair in Technology and Society and distinguished professor of communication at the University of California, Santa Barbara, the research also addresses larger questions about what it means to know someone, or rather to feel known by someone or something.
"When I tell a student her homework was better than many other students’, it’s just a numerical comparison,” Walther said. “When I tell her that her homework is better than she did earlier in the semester, she knows I know her, that she’s not just a number. The same goes for doctors: Am I just the latest lab tests, or am I unique?”

What: Young people with severe obesity who underwent weight-loss surgery at age 19 or younger continued to see sustained weight loss and resolution of common obesity-related comorbidities 10 years later, according to results from a large clinical study funded by the National Institutes of Health (NIH).
Study participants with an average age of 17 underwent gastric bypass or sleeve gastrectomy weight-loss surgery. After 10 years, participants sustained an average of 20% reduction in body mass index (BMI), 55% reduction of type 2 diabetes, 57% reduction of hypertension, and 54% reduction of abnormal cholesterol. Both gastric ...
Ten years after undergoing bariatric surgery as teens, over half of study participants demonstrated not only sustained weight loss, but also resolution of obesity-related conditions, such as type 2 diabetes, high blood pressure and high cholesterol, according to the report published in the New England Journal of Medicine.
“Our study presents impressive outcomes of the longest follow-up of weight loss surgery during adolescence, which validates bariatric surgery as a safe and effective long-term obesity management strategy,” said lead author Justin Ryder, PhD, Vice Chair of Research for the Department ...
Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children, even at levels previously thought to be safe, according to a new paper by Columbia University Mailman School of Public Health, Simon Fraser University in Canada, and Harvard Medical School, and Boston Children’s Hospital. Low-level lead poisoning is a risk factor for preterm Birth, cognitive deficits and attention deficit–hyperactivity disorder, (ADHD), as well as increased blood pressure and reduced heart rate variability. The findings ...
Biologgers allow us to see with unprecedented precision how animals move and behave in the wild. But that's only part of the picture, according to a UC Santa Cruz ecologist renowned for using biologging data to tell the deeper story about the lives of marine mammals in a changing world.
In a new opinion piece published on October 30 in Trends in Ecology and Evolution, researchers present a framework intended to underscore the value of biologging data for testing important questions about the natural world. They urge that now is the time to build upon "discovery-based science," where observations are presented ...
ROCHESTER, Minn. — Doctors at Mayo Clinic used a new catheter-based approach to draw out resistant pockets of infection that settle in the heart, known as right-sided infective endocarditis, without surgery. Unless treated quickly, the walled-off infections can grow, severely damaging heart valves and potentially affecting other organs as well. In a recent study, over 90% of the participants had their infection cleared, and they had lower in-hospital mortality compared to those whose infections remained.
The research is part of a Mayo Clinic-led study ...
Rapid side-to-side eye movements can help stabilize posture, avoid falls and maintain balance for people with Parkinson’s disease, just as they can for healthy people. This seemingly counterintuitive conclusion was reached by researchers at São Paulo State University (UNESP) in Brazil and the University of Lille in France in a study supported by FAPESP. An article on the study is published in the journal Biomechanics.
Ten individuals diagnosed with Parkinson’s and 11 neurologically healthy individuals participated in the study. All participants were over 60 and were submitted to tests that ...
PHILADELPHIA (October 30, 2024) – A new study – published in Nursing Research – has found that the COVID-19 pandemic significantly impacted patient safety indicators in U.S. hospitals. The study, from Penn Nursing’s Center for Health Outcomes and Policy Research (CHOPR), examined data from the National Database of Nursing Quality Indicators to assess trends in nursing-sensitive quality indicators from 2019 to 2022. The prevention of these very distressing, uncomfortable conditions is considered to be under the nurse’s purview and directly influenced by nursing care.
The investigation found that rates of falls, bloodstream infections from ...
MINNEAPOLIS – The amount of money people pay out-of-pocket for branded drugs to treat neurological diseases like multiple sclerosis (MS), Alzheimer’s, and Parkinson’s disease continues to rise, especially for MS drugs, according to a study published in the October 30, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found that average out-of-pocket costs for drugs for MS increased by 217% over a nine-year period.
Costs have dropped for medications where generic versions have been introduced.

Large herbivores like bison or elk have continuously lived in the Yellowstone National Park region for about 2,300 years according to a new analysis of chemicals preserved in lake sediments. John Wendt of Oklahoma State University, U.S., and colleagues present these findings in the open-access journal PLOS ONE on October 30, 2024.
The near-extinction of bison in North America in the 19th and 20th centuries was a major ecological catastrophe and little is known about where and how these animals lived before European colonization. In the new study, researchers attempted to determine the dominant large herbivores that lived in the northern Yellowstone National Park ...
