The prospect of assisting disabled patients by translating neural activity from the brain into control signals for prosthetic devices, has flourished in recent years. Current systems rely on neural activity present during natural arm movements. We propose here that neural activity present before or even without natural arm movements can provide an(More)
BACKGROUND Noninvasive positive-pressure ventilation may benefit patients with amyotrophic lateral sclerosis and respiratory insufficiency. OBJECTIVE To determine 1) whether patients tolerant of noninvasive positive-pressure ventilation have better survival than intolerant patients and 2) whether bulbar symptoms account for intolerance of noninvasive(More)
OBJECTIVE We conducted a citation analysis to explore the impact of articles published in Health Psychology and determine whether the journal is fulfilling its stated mission. DESIGN Six years of articles (N = 408) representing three editorial tenures from 1993-2003 were selected for analysis. MAIN OUTCOME MEASURES Articles were coded for several(More)
This article describes the patient-centered Scalable National Network for Effectiveness Research (pSCANNER), which is part of the recently formed PCORnet, a national network composed of learning healthcare systems and patient-powered research networks funded by the Patient Centered Outcomes Research Institute (PCORI). It is designed to be a(More)
Clinicians make many patient care decisions each day. The cumulative cognitive demand of these decisions may erode clinicians' abilities to resist making potentially inappropriate choices. Psychologists, who refer to the erosion of self-control after making repeated decisions as decision fatigue, 1,2 have found evidence that it affects nonmedical(More)
IMPORTANCE "Nudges" that influence decision making through subtle cognitive mechanisms have been shown to be highly effective in a wide range of applications, but there have been few experiments to improve clinical practice. OBJECTIVE To investigate the use of a behavioral "nudge" based on the principle of public commitment in encouraging the judicious(More)
BACKGROUND Inappropriate antibiotic prescribing for nonbacterial infections leads to increases in the costs of care, antibiotic resistance among bacteria, and adverse drug events. Acute respiratory infections (ARIs) are the most common reason for inappropriate antibiotic use. Most prior efforts to decrease inappropriate antibiotic prescribing for ARIs(More)
INTRODUCTION Poor data quality can be a serious threat to the validity and generalizability of clinical research findings. The growing availability of electronic administrative and clinical data is accompanied by a growing concern about the quality of these data for observational research and other analytic purposes. Currently, there are no widely accepted(More)
IMPORTANCE Interventions based on behavioral science might reduce inappropriate antibiotic prescribing. OBJECTIVE To assess effects of behavioral interventions and rates of inappropriate (not guideline-concordant) antibiotic prescribing during ambulatory visits for acute respiratory tract infections.
