PPRG Research Activities

The PPRG conducts practice-based research in child health through partnerships with pediatric primary care clinics.

Current Studies

Hypertension in Premature Infants in the Pediatric Office

This study is led by Lurie Children’s community physician Benjamin Kornfeld, MD, in collaboration with Lurie Children’s pediatric kidney disease specialist Gal Finer, MD, PhD.

There exist recommendations regarding blood pressure screening of children under 3 years of age who were born prematurely. However, it is not known if pediatric offices are appropriately equipped to perform the recommended screening, and how aware pediatricians are of this recommendation.

There were 26 PPRG practices that participated. Provider surveys were completed by 86 providers regarding their blood pressure screening practices of premature infants. The survey identified self-perception of adherence to the AAP Bright Futures guidelines. A total of 119 medical records of premature babies were reviewed to determine the frequency with which they are actually undergoing targeted blood pressure screening as well as the incidence of abnormally elevated measurements in this population.

An abstract from this study was accepted for a platform presentation at the 2017 Pediatric Academic Societies (PAS) meeting. Find the abstract here​.

The practices below are participating in this study.

Growing Up Healthy

This study is a retrospective review of 100 charts from each of 9 primary-care pediatric practices serving a range of racial/ethnic groups and socioeconomic classes to examine the prevalence of overweight in infants and young children.

Principal Investigator: Adolfo Ariza, MD

Project TECH: Teens Engaged in Collaborative Health

PPRG is helping the Northwestern University Center for Behavioral Intervention Technologies (CBITs) with recruiting practices to increase participation in this study. The purpose of this project is to develop scalable, cost-effective, technology-based interventions for the prevention of depression in adolescents.

Principal Investigator: David Mohr, PhD

Utilization and Cost-effectiveness of Transcutaneous Bilirubinometry in the Primary Care Setting

The goal of this study is to evaluate the accuracy of transcutaneous bilirubinometry (TcB) in a primarily Latino population of newborns presenting to a primary care practice for the evaluation of jaundice. 

Principal Investigator: Nivedita Mohanty, MD, Shannon Haymond, PhD

Past Research

Cardiovascular Risk Prevention Guidelines

Sixteen PPRG practices participated in a quality improvement study that evaluated two levels of interventions that may lead to compliance with recommendations from the new pediatric cardiovascular risk prevention guidelines (Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents, Pediatrics 2011 Dec;128 Suppl 5:S213-56). Evaluations were focused on care related to body mass index, obesity, blood pressure, and family tobacco use.
