Patterns of commutativity: the commutant of the full pattern

Identified are a number of conditions on square patterns that are closely related to allowing commutativity with the full pattern. Implications and examples that show non-implications are given, along with a graph that summarizes the provided information. A complete description of commutativity with the full pattern is given in both the irreducible case and the reducible case in which there are two irreducible components.info:eu-repo/semantics/publishedVersio

Inappropriate electrolyte repletion for patients undergoing endoscopic procedures

At Thomas Jefferson University Hospital (TJUH), there has been a perceived necessity among housestaff and fellows to routinely check and replete serum potassium and magnesium for inpatients prior to endoscopic procedures In addition, there was an unwritten policy that these electrolytes needed to be aggressively repleted, with a goal potassium above 4.0 and magnesium above 2.0 Contributing factors include absence of clear policy, fear of adverse outcomes during procedures, and fear of delay of procedures leading to increased hospital stay This practice has led to unwarranted lab draws, costs of lab tests and electrolyte riders, and possible delayed procedures Goals Clarify policies regarding electrolyte repletion Determine frequency of inappropriate electrolyte checking and repletion Determine monetary cost of this action Decrease frequency of inappropriate electrolyte lab check and repletionhttps://jdc.jefferson.edu/patientsafetyposters/1023/thumbnail.jp

Preventing Isolated Perioperative Reintubation: Who is at highest risk?

Objectives: 1. We aim to characterize IPR nationally through a retrospective review of the National Surgical Quality Improvement Program participant user file (NSQIP PUF). 2.Identify risk factors for IPR including analysis of procedure type and preoperative characteristics.https://jdc.jefferson.edu/patientsafetyposters/1041/thumbnail.jp

Coupling strength control in photonic crystal/photonic wire multiple cavity devices

Resonance splitting has been demonstrated for two coupled micro-cavities with control of the free spectral range between the resonance peaks, together with a normalised transmission level of approximately 60%. Coupled micro-cavity-based structures that were separated by two closely spaced in-line coupler sections between the two micro-cavities have also been successfully fabricated and measured. The coupling strength of the two cavities was controlled via the use of hole tapering in the middle section between the two cavities. 2D finite-difference time-domain simulation shows close agreement with the results of measurements

Quantifying Patient Reported and Documented Compliance with Adjuncts to Venous Thromboembolism Prophylaxis

Objectives: 1. Measure patient compliance with pharmacologic, mechanical and ambulatory prophylactic measures. 2. Evaluate for agreement between nursing documentation and patient reported compliance with mechanical and ambulatory prophylactic measures.https://jdc.jefferson.edu/patientsafetyposters/1042/thumbnail.jp

How good are we at determining risk? Quantifying the accuracy of clinician determined risk for VTE prophylaxis

Objectives: Create and validate a simple tool for concurrent audits of risk stratification, compliance and documentation Evaluate accuracy of clinician risk stratification and prophylatic ordering practice compared with a standardized Caprini RAM across different assigned risk categories Provide recommendations for EPIC VTE Prophylaxis CDS Developmenthttps://jdc.jefferson.edu/patientsafetyposters/1050/thumbnail.jp

Design and fabrication of high quality-factor 1-d photonic crystal/photonic wire extended microcavities

We have successfully demonstrated experimentally the fabrication and measurement of high quality-factor one-dimensional photonic crystal/photonic wire extended cavities based on silicon-on-insulator. The cavities that we have investigated ranged from 3 to 8 m in length. A quality-factor of nearly 74 000 was measured at a cavity length of 5 m through the use of tapering both within and outside the cavity, showing good agreement with the finite-difference time-domain simulation approach use

Quiet in the Operating Room! Team STEPPS and OR Distractions

Background and Objective: From the moment that a patient enters the operating room to the time that they are brought to the post anesthesia care unit, a distraction has the potential to lead to an adverse outcome for the patient. During the critical portions of the surgery, it is even more important for all members of the operating staff to be focused and engaging in safe practices. Distractions in the operating room can hinder safe communication and potentially endanger patient safety. Team training has been shown to both improve team communication and reduce distractions. The objective of this project was using Team STEPPS training to reduce distractions during the critical portions of surgery, defined as the time of anesthesia induction, the time out, and the time of emergence from anesthesiahttps://jdc.jefferson.edu/patientsafetyposters/1060/thumbnail.jp
