Iftach Sagy, Vladimir Zeldetz, Daniel Halperin, Muhammad Abu Tailakh, Victor Novack
Background: Renal colic (RC) is one of the most common reasons for emergency department (ED) visits. Although RC is associated with high ambient temperature and with physiological changes that occur during fast, the literature onbetween Ramadan and RC incidence is scarce. Methods: We obtained health data of patients visited the emergency department (ED) of a large tertiary center during the years 2004-2015, with a primary diagnosis of RC. To estimate the association of RC and Ramadan, we utilized bi-weekly RC incidence Poisson models adjusted for ambient temperature and seasonality in two ethnic groups residing in the region: Muslims and Jews...

BACKGROUND: Emergency medicine residents need to be staffed in a way that balances operational needs with their educational experience. Key to developing an optimal schedule is knowing a resident's expected productivity, a poorly understood metric. OBJECTIVE: We sought to measure how a resident's busiest (peak) workload affects their overall productivity for the shift. METHODS: We conducted a retrospective, observational study of resident productivity at an urban, tertiary care center with a 3-year Accreditation Council for Graduate Medical Education-approved emergency medicine training program, with 55,000 visits annually...

INTRODUCTION: Lactate levels are increasingly used to risk stratify emergency department (ED) patients with and without infection. Whether a serum lactate provides similar prognostic value across diseases is not fully elucidated. This study assesses the prognostic value of serum lactate in ED patients with and without infection to both report and compare relative predictive value across etiologies. METHODS: We conducted a prospective, observational study of ED patients displaying abnormal vital signs (AVS) (heart rate ≥130 bpm, respiratory rate ≥24 bpm, shock index ≥1, and/or systolic blood pressure <90 mmHg)...

BACKGROUND: Preoperative hemoglobin A1c (HbA1c) and postoperative glycemic variability predict major adverse events (MAEs) after coronary artery bypass grafting in a protocolized glycemic control setting. However, the influence of preoperative HbA1c and postoperative glycemic variability in isolated cardiac valvular surgery is unknown. In this study, we sought to establish (a) whether preoperative HbA1c could identify patients at increased risk of MAEs and (b) whether postoperative glycemic variability was associated with MAEs after isolated cardiac valvular surgery...

Abuse of opioid prescription drugs has become an epidemic across the developed world. Despite the fact that emergency physicians overall account for a small proportion of total opioids prescribed, the number of prescriptions has risen dramatically in the past decade and, to some degree, contributes to the available supply of opioids in the community, some of which are diverted for non-medical use. Since successfully reducing opioid prescribing on the individual level first requires knowledge of current prescribing patterns, we sought to determine to what extent variation exists in opioid prescribing patterns at our institution...
