Advances in drugs, devices, and biological products that change the way health care is delivered. LDI Senior Fellows study the adoption and diffusion of medical technologies and assesses their impact on costs and quality of care.

Effect Of Behavioral Economic Incentives For Colorectal Cancer Screening In A Randomized Trial

Shivan J. Mehta, MD, MBA
Jul. 2, 2020

Shivan J. Mehta, Catherine Reitz, Tess Niewood, Kevin G. VolppDavid A. Asch

Abstract [from journal]

Background & aims: Financial incentives might increase participation in prevention such as screening colonoscopy. We studied whether incentives informed by behavioral economics increase participation in risk assessment for colorectal cancer (CRC) and completion of colonoscopy for eligible adults.

Methods: Employees of a large academic health system (50-64 y old; n=1977) were randomly assigned to groups that underwent risk assessment for CRC screening and direct access colonoscopy scheduling

Suprapubic Versus Urethral Catheter For Urinary Drainage After Robot-Assisted Radical Prostatectomy

Leilei Xia
Jun. 6, 2020

Leilei Xia, Thomas J Guzzo, Phillip Mucksavage, Daniel J. Lee 

Abstract [from journal]

Purpose of review: To review the evidence regarding the usage of suprapubic tube (SPT) versus indwelling urethral catheter (IUC) after robot-assisted radical prostatectomy (RARP).

Recent findings: Available data on the use of SPT for urinary drainage after RARP is somewhat limited mostly because of the variations of study designs and non-standardized outcomes. Although it may provide some mild benefit in terms of catheter-related pain and discomfort, the benefit seems not to be clinically

Abstract [from journal]

Importance: Incoming text messages and calls on nurses’ mobile telephones may interrupt medication administration, but whether such interruptions are associated with errors has not been established.
 

Objective: To assess whether a temporal association exists between mobile telephone interruptions and subsequent errors by pediatric intensive care unit (PICU) nurses during medication administration.

Design, Setting, and Participants: A retrospective cohort study was...

Can Machine Learning Improve Cancer Care?

Oct. 25, 2019

“How long do I have?”

It is the first question many patients ask after a cancer diagnosis. It is also among the hardest to answer. For decades, predicting cancer survival was more art than science. But now, unprecedented computing power and access to digital health information offer a tantalizing opportunity: can machine learning (ML) algorithms succeed where others fail?

Electronic Pill Bottles or Bidirectional Text Messaging to Improve Hypertension Medication Adherence (Way 2 Text): a Randomized Clinical Trial

Shivan J. Mehta, Kevin G. Volpp, Andrea B. Troxel, Susan C. Day, Raymond Lim, Noora Marcus, Laurie Norton, Sophia Anderson, David A. Asch

Abstract [from journal]

Background: Poor medication adherence contributes to inadequate control of hypertension. However, the value of adherence monitoring is unknown.

Objective: To evaluate the impact of monitoring adherence with electronic pill bottles or bidirectional text messaging on improving hypertension control.

Design: Three-arm pragmatic randomized controlled trial.

Patients: One hundred forty-nine primary care patients aged 18-75 with hypertension and text messaging capabilities who

Rise of the Machines in Health Care?

Feb. 22, 2019

Artificial intelligence (AI) is moving fast and breaking things everywhere. It is built into multinational supply chains, web-based services, cars, and, slowly, health care. Although the adoption of AI in health care has been bumpy, it continues unabated. Last year, the U.S.

Does Bad News Travel Faster? On the Determinants of Medical Technology Abandonment

Dec. 20, 2018

Julie Berez, Guy David, David H. Howard, Mark D. Neuman

ABSTRACT [FROM JOURNAL]

This paper studies the abandonment of technology in reaction to information shocks. While the diffusion of new technologies has been widely researched, the factors driving abandonment are not well understood. This is particularly important in the health care sector, where curbing overuse of low-value technologies is a priority. Using the abandonment of pulmonary artery catheters (PACs) as an empirical application, we aim to understand patterns of human behavior when information that a technology is ineffective becomes available. This study focuses on the...

Can We Afford to Cure Cancer?

Oct. 26, 2018

Novel gene and cell therapies hold out the promise of a cure for previously incurable conditions, often at eye-popping prices. Last month, more than 75 health policy and biomedical researchers, federal and state regulators, and clinicians convened at the Cost of a Cure Conference at the University of Pennsylvania to discuss key political, economic, and clinical challenges to the future of gene and cell therapies.

Effect of Continuing Care for People with Cocaine Dependence on Criminal Justice Sentences

Sep. 19, 2018

Alexandra S. Wimberly, Jordan M. Hyatt , James R. McKay

ABSTRACT [FROM JOURNAL]

While continuing care for substance use treatment has been associated with reduced involvement in the criminal justice system, much of this research lacks random assignment to continuing care and so is limited by self‐selection bias. This study sought to determine the impact of adding telephone‐based continuing care to intensive outpatient programs on criminal justice outcomes for people with cocaine dependence. In three continuing care studies, spanning 1998–2008, participants were randomly assigned to an intensive outpatient program or an intensive...
