Wearable Devices To Monitor And Reduce The Risk Of Cardiovascular Disease: Evidence And Opportunities

Sep. 4, 2020

Atsushi Mizuno, Sujatha Changolkar, Mitesh S. Patel

Abstract [from journal]

There is a growing interest in using wearable devices to improve cardiovascular risk factors and care. This review evaluates how wearable devices are used for cardiovascular disease monitoring and risk reduction. Wearables have been evaluated for detecting arrhythmias (e.g., atrial fibrillation) as well as monitoring physical activity, sleep, and blood pressure. Thus far, most interventions for risk reduction have focused on increasing physical activity. Interventions have been more successful if the use of wearable devices is

Pooled Sampling of COVID-19 Tests Holds Promise

Aug. 25, 2020

Testing, as a mainstay of an effective response to COVID-19, requires sufficient supply to meet the demand. However, since the pandemic hit the US, this has not been the case. While governments have focused on procuring and producing additional tests, researchers have focused on finding ways to make the tests we do have more efficient.

Abstract [from journal]

Introduction: Primary care remains an underused venue for prevention and management of paediatric overweight and obesity. A prior trial demonstrated a significant impact of paediatrician/nurse practitioner (Ped/NP)-and registered dietitian (RD)-delivered motivational interviewing (MI) on child body mass index (BMI). The study described here will test the effectiveness of an enhanced version of this primary care-based MI counselling intervention on child BMI.

Methods and analysis: This cluster

The Contemporary Landscape Of Genetic Testing And Breast Cancer: Emerging Issues

Jul. 20, 2020

Payal D. Shah, Susan M. Domchek

Abstract [from journal]

The landscape of genetic testing for breast cancer susceptibility has transformed dramatically over the last decade and a half. Traditionally, the process of genetic testing resided fully within a medical infrastructure, from identification of appropriate testing candidates to gene selection to risk mitigation recommendations. More recently, decreasing costs, advancing technology, and a growing understanding of therapeutic implications of certain genetic test results have led to more widespread uptake of testing that increasingly

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

Vaccine Rationing And The Urgency Of Social Justice In The Covid-19 Response

May. 28, 2020

Harald Schmidt

Abstract [from journal]

The Covid-19 pandemic needs to be considered from two perspectives simultaneously. First, there are questions about which policies are most effective and fair in the here and now, as the pandemic unfolds. These polices concern, for example, who should receive priority in being tested, how to implement contact tracing, or how to decide who should get ventilators or vaccines when not all can. Second, it is imperative to anticipate the medium- and longer-term consequences that these policies have. The case of vaccine rationing is

A Randomized Trial of Behavioral Nudges to Improve Enrollment in Critical Care Trials

May. 22, 2020

Dustin C. Krutsinger, Kelly L. O'Leary, Susan S. Ellenberg, Cody E. Cotner, Scott D. Halpern, Katherine R. Courtright

Abstract [from journal]

Rationale: Low and slow patient enrollment remains a barrier to critical care randomized controlled trials (RCTs). Behavioral economic insights suggest that nudges may address some enrollment challenges.

Objectives: To evaluate the efficacy of a novel pre-consent survey consisting of nudges on critical care RCT enrollment.

Methods: We conducted an RCT in 10 intensive care units (ICUs) among surrogate decision-makers (SDMs). The novel multi-component behavioral nudge survey was...

May. 17, 2020

Kara J Pavone, Juliane Jablonski, Paul Junker, Pamela Z Cacchione, Peggy Compton, Rosemary C Polomano

Abstract [from journal]

Background: Delirium is prevalent in hospitalized older adults. Little is known about delirium among older adults admitted to the surgical intensive care unit (SICU).

Objectives: The purpose of this study was to describe the incidence of delirium, length of stay, 30-day readmission and mortality rates experienced by older adults in the SICU before and after a nurse-driven protocol for delirium-informed care.

Methods: This study employed a retrospective observational cohort...

Identifying the Organizational Innovation-specific Capacity Needed for Exposure Therapy

May. 10, 2020

Emily M. Becker‐Haimes, Young Vivian Byeon, Hannah E. Frank, Nathaniel J. Williams, Hilary E. Kratz, Rinad S. Beidas
 

Abstract [from journal]

Background: Current approaches to increasing the rates of clinician use of exposure therapy for anxiety disorders in community settings are limited. Research underscores the importance of addressing contextual variables to facilitate clinician use of evidence-based practices; however, no studies have identified the innovation-specific organizational capacity necessary to implement exposure therapy. Such work is critical to ensure that treatment-seeking individuals with anxiety receive effective care.

Association of Utilization Management Policy With Uptake of Hypofractionated Radiotherapy Among Patients With Early-Stage Breast Cancer

Apr. 16, 2020

Ravi B. Parikh, Ezra Fishman, Winnie Chi, Robert P. Zimmerman, Atul Gupta, John J. Barron, Gosia Sylwestrzak, Justin E. Bekelman

Abstract [from journal]

Importance: Breast cancer accounts for the largest portion of cancer-related spending in the United States. Although hypofractionated radiotherapy after breast-conserving surgery is a cost-effective and convenient treatment strategy for patients with early-stage breast cancer, less than 40% of eligible women received hypofractionated radiotherapy in 2013.

Objective: To assess the association of a large commercial payer's utilization management policy with the use of hypofractionated radiotherapy among women

Abstract [from journal]

Background: Utilization of robotic proctectomy (RP) for rectal cancer has steadily increased since the inception of robotic surgery in 2002. Randomized control trials evaluating the safety of RP are in process to better understand the role of robotic assistance in proctectomy. This study aimed to characterize the trends in the use of RP for rectal cancer, and to compare oncologic outcomes with center-level RP volume.

Materials and Methods: 8107 patients with rectal adenocarcinoma who underwent RP were
