Background: Group medical visits (GMV) effectively improve patient care and outcomes through interactive education, increased patient contact, and facilitated social support. This quality improvement research examined if patient activation and quality of life correlate with weight, blood pressure (BP), and hemoglobin A1c (A1C) through GMV interventions.

Methods: Participants were enrolled in GMV Lighten Up for weight management or GMV Diabetes.

Background: One-half of all people who undergo lung cancer screening (LCS) currently use tobacco. However, few published studies have explored how to implement effective tobacco use treatment optimally during the LCS encounter.

Research Question: Was the Optimizing Lung Screening intervention (OaSiS) effective at reducing tobacco use among patients undergoing LCS in community-based radiology facilities?

Study Design And Methods: The OaSiS study (National Cancer Institute [NCI] Protocol No.

The reinforcing characteristics of e-cigarettes could moderate the impact of reducing cigarette nicotine content. In this study, people who smoke daily were recruited from North Carolina and Pennsylvania (US) in 2018 and 2019. Within a randomized 2 × 2 × 2 factorial design, participants received investigational cigarettes and an e-cigarette for 12 weeks.

Introduction: E-cigarettes have been marketed illicitly as smoking cessation aids and reduced risk tobacco products in the United States. Our study assessed consumers' exposure to such claims and evaluated their impact on relative risk perceptions and e-cigarette use.

Methods: Data are from the Assessment of the post-College Experience study, which followed a cohort of young adults since 2010 when they were college freshmen.

In Spring 2020, most US states and territories implemented stay-at-home orders to slow transmission of the novel coronavirus SARS-CoV2, the cause of COVID-19. Little is known about the impact of stay-at-home orders on tobacco and nicotine use including among young adults. The current study examined participants (N = 1727) completing three recent survey waves from a longitudinal cohort of young adults recruited in 2010 from North Carolina and Virginia, USA: Wave 13 (Spring 2019), Wave 14 (Fall 2019), and Wave 15 (Spring 2020) to assess changes in cigarette and e-cigarette use.

Objective: Food insecurity (FI) affects approximately 11·1 % of US households and is related to worsened infant outcomes. Evidence in lower income countries links FI and infant mortality rates (IMR), but there are limited data in the USA. This study examines the relationship between FI and IMR in North Carolina (NC).

Introduction: In light of the opioid overdose epidemic in the US and the necessity of developing training to conduct difficult conversations around opioid dependence, three case-based videos were created to demonstrate providers using motivational interviewing (MI) with patients who have opioid use disorder (OUD). These vignettes displayed a primary care provider interacting with a patient seeking opioids.

Methods: Learners-including third-year medical and physician assistant (PA) students, and family medicine residents-viewed three videos set in a family medicine clinic and assessed clinician use of MI when interacting with patients with OUD.

Opioid use and overdose are escalating in the United States. Primary care providers are in a strategic position to assess patients for medication-assisted treatment (MAT). To describe the implementation of MAT in an integrated primary care residency clinic and assess provider comfort levels with evaluating patients for high-risk opioid use, conduct crucial conversations about MAT treatment options and referral to MAT for evaluation and treatment.

Article Synopsis
  • Colorectal cancer is a leading cause of cancer-related deaths in the U.S., with many Americans not getting screened; the mPATH-CRC iPad decision aid has previously shown to significantly increase screening rates.
  • In a randomized controlled trial, data from 408 patients revealed that mPATH-CRC had a major impact on screening completion, with various mediators accounting for about 76% of its effectiveness.
  • The most significant factor influencing screening was communication between patients and providers, highlighting the importance of digital tools like mPATH-CRC in enhancing patient-provider interactions.

Introduction: When the Centers for Medicare and Medicaid Services announced coverage for low dose CT lung cancer screening, they also mandated that imaging centers offer smoking cessation services. We designed the Optimizing Lung Screening (OaSiS) trial to evaluate strategies to implement the Public Health Service Guidelines for Treating Tobacco Use and Dependence during CT screening for lung cancer.

Methods And Design: OaSiS was implemented using a pragmatic effectiveness-implementation hybrid design in 26 imaging clinics across the United States affiliated with the National Cancer Institute's National Community Oncology Research Program (NCORP).

: Patients with diabetes must navigate multiple components of care to self-manage their disease. Group Medical Visits (GMVs) are a forum for patients to see a provider as well as actively participate in education and care management with other patients with diabetes. The objective is to describe GMV implementation and resident involvement in a primary care setting.

Objective: Colleges have implemented policies to limit tobacco use on-campus; however, the off-campus environment is often overlooked in tobacco control efforts. We assessed availability, marketing, and promotion of cigarettes, snus, and traditional smokeless tobacco (SLT) in a sample of communities surrounding 11 college campuses in North Carolina and Virginia.

Participants: Between January-March of 2011, 2012 and 2013, 481 tobacco-selling retailers, including convenience stores, pharmacies and supermarkets, located near campuses were assessed.

Background: Individuals with mental health conditions represent a priority population for tobacco control. This population smokes cigarettes at disproportionately higher rates than the general population, but less is known about the relationship between non-cigarette tobacco use and mental health status.

Method: In 2013, 2370 young adults recruited from 11 colleges in North Carolina and Virginia completed an online survey on tobacco use.

Background: Recent advances in mobile technologies have created new opportunities to reach broadly into populations that are vulnerable to health disparities. However, mobile health (mHealth) strategies could paradoxically increase health disparities, if low socioeconomic status individuals lack the technical or literacy skills needed to navigate mHealth programs.

Objective: The aim of this study was to determine whether patients from vulnerable populations could successfully navigate and complete an mHealth patient decision aid.

Background: Marijuana is the most commonly used illicit drug by college students. Prior studies have established an association between marijuana use and poor academic performance in college, but research on the frequency of marijuana use over the entire college career is limited. The study objective was to examine the association of marijuana use trajectories on academic outcomes, including senior year enrollment, plans to graduate on time, and GPA.
