Although large-scale genetic association studies involving hundreds to thousands of SNPs have become feasible, the associated cost is substantial. Even with the increased efficiency introduced by the use of tagSNPs, researchers are often seeking ways to maximize resource utilization given a set of SNP-based gene-mapping goals. We have developed a web server(More)
OBJECTIVE To determine whether year of residency is associated with intraoperative phacoemulsification complication rates. DESIGN Retrospective cohort study. PARTICIPANTS One attending physician supervised 691 resident-performed phacoemulsification procedures on 492 patients. Second- and third-year residents performed 228 and 463 cases, respectively.

BACKGROUND Emergency department (ED) human immunodeficiency virus (HIV) screening programs are challenged by the unsustainable cost of exogenous staff and the relatively low penetration rates. Kiosk systems have increased registration efficiency in various clinical settings and have shown promising results for advancing various public health initiatives.(More)
It is widely recognized that the demand for emergency services is rising. Emergency department (ED) utilization increased from 36.9 visits per 100 persons per year in 1995 to 42.8 in 2010 [1,2]. With increasingly timeand personnel-constrained EDs, self-service kiosks have emerged as one potential solution to perform simple tasks such as registration and(More)
PURPOSE To determine whether supervision by an attending who is new to surgical teaching, or an experienced attending measurably influences intraoperative complications rates or outcomes in phacoemulsification performed by ophthalmology residents. SETTING Single tertiary hospital. DESIGN Retrospective cohort study. METHODS Resident-performed(More)
Kiosk-facilitated HIV self-testing has been shown to be accurate and well accepted by emergency department (ED) patients. We investigated factors associated with patients who preferred self-testing over testing performed by health professionals in an ED-based HIV screening program. This opt-in program evaluation studied 332 patients in an inner-city(More)
BACKGROUND Because more than one-third of the U.S. population visits an emergency department (ED) any given year, public health interventions in the ED can have major population-level impacts. OBJECTIVES We determined ED patients' interest in receiving information via kiosk on common, chronic conditions for which education and preventive screening could(More)
We evaluated the feasibility and the patient acceptability of integrating a kiosk into routine emergency department (ED) practice for offering HIV testing. The work was conducted in four phases: phase 1 was a baseline, in which external testing staff offered testing at the bedside; phase 2 was a pilot assessment of a prototype kiosk; phase 3 was a pilot(More)
