Improving Patient Safety by Calculating the QT Correction in Critical Care Patients

Prolonged QTc is recognized as a precursor to Torsades de Points and other lethal ventricular arrhythmias. 52% or patients in critical care units have prolonged QTc and 69% or critical care patients have risks of developing QTc. Many commonly administered medications in the critical care unit are known to prolong QTc yet a microsystem assessment and a gap analysis revealed only 3% of the patients in the surgical ICU had the QTc calculation performed and assessed by the critical care nurse. The global aim is to improve patient safety by incorporating calculating of the QT correction (QTc) into the regularly performed assessments of the patients in the Surgical Intensive Care Unit. Performing this measurement will identify prolonged QTc, a known precursor to Torsades de Pointes and other lethal ventricular arrhythmias. Critical care nurses and the interdisciplinary team will intervene proactively for these critically ill patients. The specific aim is to reach 90% compliance with calculating and documenting the QTc by September 1, 2015. Nursing education through staff huddles, educational fliers, and one on one demonstration was provided throughout July 2015. Through interventions to improve nurses’ awareness of QTc calculation and risks of prolonged QTc intervals, compliance with calculating QTc has improved from 3% to 82%. Surveys were administered pre and post education which showed nurses self-reported comfort level has increased from 75% to 95% with no one reporting least comfort at the end of the intervention

Variations in the phosphorus content of estuarine waters of the Chesapeake Bay near Solomons Island, Maryland

Studies by Cowles and Brambel (1938), Newcombe and Lang (1939), and Newcombe, Horne and Shepherd (1939) have provided information on the quantitative methods for estimating inorganic phosphorus and, also, on the vertical and horizontal distribution of this nutrient substance in the waters of the Chesapeake Bay...

Observations on the alkalinity of estuarine waters of the Chesapeake Bay near Solomons Island, Maryland

Kolthoff (1926) without particular reference to sea water has defined buffer capacity (alkalinity, in the case of added strong base) of a solution quantitatively as the number of equivalents of added strong base or strong acid required to change the pH of one liter of solution one unit. Buch, in 1930, redefined this concept with reference to sea water as the number of moles of carbonic acid which must be added to one liter of the water in order to change its pH by one unit

Reorienting with terrain slope and landmarks

Orientation (or reorientation) is the first step in navigation, because establishing a spatial frame of reference is essential for a sense of location and heading direction. Recent research on nonhuman animals has revealed that the vertical component of an environment provides an important source of spatial information, in both terrestrial and aquatic settings. Nonetheless, humans show large individual and sex differences in the ability to use terrain slope for reorientation. To understand why some participants—mainly women—exhibit a difficulty with slope, we tested reorientation in a richer environment than had been used previously, including both a tilted floor and a set of distinct objects that could be used as landmarks. This environment allowed for the use of two different strategies for solving the task, one based on directional cues (slope gradient) and one based on positional cues (landmarks). Overall, rather than using both cues, participants tended to focus on just one. Although men and women did not differ significantly in their encoding of or reliance on the two strategies, men showed greater confidence in solving the reorientation task. These facts suggest that one possible cause of the female difficulty with slope might be a generally lower spatial confidence during reorientation

Using analogy to learn about phenomena at scales outside of human perception

Understanding and reasoning about phenomena at scales outside human perception (for example, geologic time) is critical across science, technology, engineering, and mathematics. Thus, devising strong methods to support acquisition of reasoning at such scales is an important goal in science, technology, engineering, and mathematics education. In two experiments, we examine the use of analogical principles in learning about geologic time. Across both experiments we find that using a spatial analogy (for example, a time line) to make multiple alignments, and keeping all unrelated components of the analogy held constant (for example, keep the time line the same length), leads to better understanding of the magnitude of geologic time. Effective approaches also include hierarchically and progressively aligning scale information (Experiment 1) and active prediction in making alignments paired with immediate feedback (Experiments 1 and 2)
