New research finds utilizing telemedicine in the ER can reduce wait times and patient length of stay
Telemedicine has become more common given the current global pandemic. COVID-19 has limited doctor’s office and hospital visits to ensure safety for everyone. But rather than diminish the quality of care, new research coauthored by Purdue's Susan Lu in the INFORMS journal Information Systems Research finds that increasing wider use of telemedicine in the emergency room (ER) can yield positive results for patients and providers alike.

Does Technology Replace Nurses? Not necessarily...
Nurses have many duties, but none is more important than providing bedside care to patients. A research study co-authored by Susan F. Lu, associate professor of management in Purdue's Krannert School of Management, shows some nurses may lose their jobs when automation arrives at their workplaces. But the reverse may happen at other healthcare facilities: new technology may spark the hiring of more nurses.

Good Medicine
Looking for a high-caliber surgeon may be easier than previously thought. Critics of online rating platforms have stated that online physicians’ ratings are nothing more than a popularity contest, but a new study by Susan Lu, a professor at the Purdue University Krannert School of Management, suggests that the time-honored word-of-mouth method for finding quality health care may hold up after all.

Nursing home industry asks for immunity from COVID-19 crisis
As Covdi-19 deaths and cases escalate, legislators wrestle with the issue of legal immunity for nursing homes, which house some of the most vulnerable patients. At the request of the senior-care industry, more than 20 states have passed new laws to shield senior-care facilities from coronavirus-related litigation or protected them through executive orders. Krannert faculty expert Susan Lu comments on the issue.
Malpractice laws may shield nursing homes from liability during Covid-19 pandemic
As nursing homes continue to emerge as Covid-19 hot spots, allegations of negligence are likely to increase among residents, their families and advocacy groups, according to Barron's. However, a study co-authored by Susan Lu, Gerald Lyles Rising Star Associate Professor of Management at Purdue's Krannert School, suggests that malpractice laws in many states allowing nursing homes to shield their assets could also decrease potential settlements resulting from the pandemic.
The case for economics—by the numbers
A new study examines 140,000 economics papers published from 1970 to 2015, tallying the “extramural” citations that economics papers received in 16 other academic fields, including sociology, medicine, and public health. A paper co-authored by associate professor Susan Feng Lu appears in the March issue of the Journal of Economic Literature.
Who Gets Blamed When a Group Project Goes Wrong?
Consequences stick to some team members more than others, according to a new study of retracted academic papers based on research co-authored by Krannert Professor Susan Feng Lu. The researchers looked at retracted academic articles with multiple authors and compared how frequently each author continued to be cited by fellow scholars following the retraction. Crunching the numbers, they found that the more junior members of the team saw a substantial decline in citations of their work, while the more eminent members experienced little or no change.
Three-Day Stay Rule Generates Up to $447M in Extra Medicare Spending
The three-day hospital stay rule required for Medicare to cover subsequent skilled nursing facility stays may have generated millions in extra payments to SNFs, a new working paper from the National Bureau of Economic Research suggests.
Study by Krannert prof Susan Lu shows cardiac surgeons’ online ratings prove reliable
Looking for a high-caliber surgeon may be easier than previously thought. Critics of online rating platforms have stated that online physicians’ ratings are nothing more than a popularity contest, based on the interpersonal encounter a patient has with their doctor, rather than on the doctor’s attentiveness to current best practices. Even though the system has been met with skepticism, a new study suggests that the time-honored word-of-mouth method for finding quality health care may hold up after all.
Economics gets out more often: Using extramural citations to assess economic scholarship
Economics, and economists, are often accused of insularity and hubris, and of talking primarily to themselves in their research. This column, coauthored by Krannert's Susan Lu, uses a recent analysis of citations to and from other disciplines to show that this is no longer the case.
Checking the pulse on health-care staffing
Working long hours takes a toll. It also can be counterproductive and is commonly linked to more stress and errors.
Doing the right thing: Scientists reward authors who report their own errors, says study
We’ve always like to highlight cases in which scientists do the right thing and retract problematic papers themselves, rather than being forced to by editors and publishers.
