The frequency with which anesthesiologists or nurse anesthetists provide sedation for gastrointestinal endoscopies, especially low-risk patients, is poorly understood and controversial.To quantify temporal comparisons regional variation in the use of payment gastroenterology anesthesia services.A retrospective analysis claims data a 5% representative sample Medicare fee-for-service patients (1.1 million adults) 5.5 commercially insured between 2003 2009.Total number upper endoscopies...
Many believe that fear of malpractice lawsuits drives physicians to order otherwise unnecessary care and legal reforms could reduce such wasteful spending. Emergency practice in an information-poor, resource-rich environment may lend itself costly defensive practice. Three states, Texas (in 2003), Georgia 2005), South Carolina enacted legislation changed the standard for emergency gross negligence. We investigated whether these substantial practice.Using a 5% random sample Medicare...
<h3>Importance</h3> The Institute of Medicine described diagnostic error as the next frontier in patient safety and highlighted a critical need for better measurement tools. <h3>Objectives</h3> To estimate proportions emergency department (ED) visits attributable to symptoms imminent ruptured abdominal aortic aneurysm (AAA), acute myocardial infarction (AMI), stroke, dissection, subarachnoid hemorrhage (SAH) that end discharge without diagnosis; evaluate longitudinal trends; identify...
In recent years, mass-casualty incidents (MCIs) have become more frequent and deadly, while emergency department (ED) crowding has grown steadily worse widespread. The ability of hospitals to implement an effective surge plan, immediately expertly, therefore never been important. Yet, exercises tend be highly choreographed, pre-scheduled events that provide limited insight into hospitals' true capacity respond a no-notice event under real-world conditions. To address this gap, the US...
Background Hospital-acquired pressure injuries (HAPIs) are publicly reported in the USA and used to adjust Medicare payment acute inpatient facilities. Current methods identify HAPIs administrative claims rely on hospital-reported present-on-admission (POA) data instead of prior patient health information. Objective To study reliability for injury (PI) stage by evaluating diagnostic coding agreement across interfacility transfers. Methods Using 2012 100% Provider Analysis Review file, we...
Most emergency department (ED) patients arrive by their own transport and, for various reasons, may not choose the nearest ED. How far travel ED treatment reflect both patients' access to care and severity of illness. In this study, we aimed examine distance time between a patient's home they visited investigate how these distances/times vary patient hospital characteristics.We randomly sampled collected data from 14,812 discharged community (DTC) January March 2016 50 hospital-based EDs...
Objectives To evaluate national present‐on‐admission (POA) reporting for hospital‐acquired pressure ulcers (HAPUs) and examine the impact of quality measure exclusion criteria on HAPU rates. Data Sources/Study Setting Medicare inpatient, outpatient, nursing facility data as well independent provider claims (2010–2011). Study Design Retrospective cross‐sectional study. Collection/Extraction Methods We evaluated acute inpatient hospital admissions among fee‐for‐service (FFS) beneficiaries in...
