The Impact of Computerized Provider Order Entry (CPOE) on Medication Order Processing and Workflow Efficiency by Pharmacists: A Time and Motion Study

Introduction: Recently, there has been a tremendous increase in the preparation on the part of US hospitals to implement CPOE. Employer groups, the federal government, and others have been advocating its implementation since the early 2000s, yet the number of hospitals which have met meaningful use criteria for CPOE is still less than 15%. This number is projected to increase exponentially in a very short time, spurred by incentives from the Centers for Medicare and Medicaid (CMS). With such a large amount of hospitals preparing for CPOE implementation, there is still much to learn about the impact of these systems. The objective of this study is to quantify the change in pharmacist workflow after CPOE is implemented. Methods: An experimental, enhanced pretest-posttest, prospective, time and motion study was conducted in four inpatient pharmacies within the same hospital system. Order entry pharmacists were observed for two separate time periods. The intervention pharmacy was observed first as a non-CPOE pharmacy and then later, after CPOE had been implemented. There was a control pharmacy which was non-CPOE for both time periods. There were two treatment control pharmacies, both of which had CPOE for both time periods. A database instrument recorded 37 different pharmacist tasks, which were grouped into four activities: clinical, distributive, administrative, and miscellaneous. Comparisons of the amount of time spent by the order entry pharmacist in each of the four different activities were conducted. SAS® version 9.3 was used to analyze the data, with statistical significance set at 0.05. Results: A total of 114 hours at the non-CPOE site and 197 hours at the CPOE site met the inclusion criteria. Non-parametric linear regressions were modeled and the predicted values were analyzed. The predicted mean number of minutes for each recorded hour were, by activity (predicted mean ± SD for non-CPOE versus CPOE, p-value): clinical (5.10 ± 2.24 versus 3.83 ± 1.34, p<0.05); distributive (44.55 ± 1.07 versus 47.61 ± 1.43, p<0.05); administrative (7.25 ± 2.34 versus 6.67 ± 1.28, p<0.05); and miscellaneous (3.11 ± 0.77 versus 1.89 ± 0.68, p<0.05). Conclusions: Less time was spent in the clinical, administrative, and miscellaneous activities, while more time was spent in the distributive activity after CPOE implementation. These findings were statistically significant.Pharmacological and Pharmaceutical Sciences, Department o

Changes in Pharmacy Students After Experiencing Interprofessional Education Activities

Background: Interprofessional education (IPE) has become increasingly important among healthcare professionals. The purpose of this study was to assess the impact of IPE experiences on pharmacy students’ perceived level of comfort with and level of reliability regarding other healthcare professionals. Methods and Findings: A survey of third- and fourth-year pharmacy students (N = 190) was analyzed using descriptive statistics and bivariate analyses to address the study objectives. Students experienced a significant increase in their level of comfort with questioning other professions after IPE (pre IPE: 5.45 ± 2.24 and post IPE: 7.22 ± 1.62, p<0.01) and being questioned by other professions (pre IPE: 5.39 ± 2.24 and post IPE: 7.04 ± 1.68, p<0.01). Students also experienced a significant increase in the perceived reliability and accuracy of information from nurses after IPE (pre IPE: 5.91 ± 1.82 and post IPE: 6.41 ± 1.62, p = 0.01). Conclusions: Pharmacy students who experienced any IPE perceived themselves as more comfortable with questioning and being questioned by other healthcare professionals than students without IPE. Additional research is needed to more clearly define the benefits of IPE and how it should be designed

Joint modeling of longitudinal outcomes and survival using latent growth modeling approach in a mesothelioma trial

Joint modeling of longitudinal and survival data can provide more efficient and less biased estimates of treatment effects through accounting for the associations between these two data types. Sponsors of oncology clinical trials routinely and increasingly include patient-reported outcome (PRO) instruments to evaluate the effect of treatment on symptoms, functioning, and quality of life. Known publications of these trials typically do not include jointly modeled analyses and results. We formulated several joint models based on a latent growth model for longitudinal PRO data and a Cox proportional hazards model for survival data. The longitudinal and survival components were linked through either a latent growth trajectory or shared random effects. We applied these models to data from a randomized phase III oncology clinical trial in mesothelioma. We compared the results derived under different model specifications and showed that the use of joint modeling may result in improved estimates of the overall treatment effect

The genomes of two key bumblebee species with primitive eusocial organization

Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome sequences of Bombus terrestris and Bombus impatiens, two ecologically dominant bumblebees and widely utilized study species. Comparing these new genomes to those of the highly eusocial honeybee Apis mellifera and other Hymenoptera, we identify deeply conserved similarities, as well as novelties key to the biology of these organisms. Some honeybee genome features thought to underpin advanced eusociality are also present in bumblebees, indicating an earlier evolution in the bee lineage. Xenobiotic detoxification and immune genes are similarly depauperate in bumblebees and honeybees, and multiple categories of genes linked to social organization, including development and behavior, show high conservation. Key differences identified include a bias in bumblebee chemoreception towards gustation from olfaction, and striking differences in microRNAs, potentially responsible for gene regulation underlying social and other traits. Conclusions: These two bumblebee genomes provide a foundation for post-genomic research on these key pollinators and insect societies. Overall, gene repertoires suggest that the route to advanced eusociality in bees was mediated by many small changes in many genes and processes, and not by notable expansion or depauperation

The use of gamma-irradiation and ultraviolet-irradiation in the preparation of human melanoma cells for use in autologous whole-cell vaccines

<p>Abstract</p> <p>Background</p> <p>Human cancer vaccines incorporating autologous tumor cells carry a risk of implantation and subsequent metastasis of viable tumor cells into the patient who is being treated. Despite the fact that the melanoma cell preparations used in a recent vaccine trial (Mel37) were gamma-irradiated (200 Gy), approximately 25% of the preparations failed quality control release criteria which required that the irradiated cells incorporate ³H-thymidine at no more than 5% the level seen in the non-irradiated cells. We have, therefore, investigated ultraviolet (UV)-irradiation as a possible adjunct to, or replacement for gamma-irradiation.</p> <p>Methods</p> <p>Melanoma cells were gamma- and/or UV-irradiated. ³H-thymidine uptake was used to assess proliferation of the treated and untreated cells. Caspase-3 activity and DNA fragmentation were measured as indicators of apoptosis. Immunohistochemistry and Western blot analysis was used to assess antigen expression.</p> <p>Results</p> <p>UV-irradiation, either alone or in combination with gamma-irradiation, proved to be extremely effective in controlling the proliferation of melanoma cells. In contrast to gamma-irradiation, UV-irradiation was also capable of inducing significant levels of apoptosis. UV-irradiation, but not gamma-irradiation, was associated with the loss of tyrosinase expression. Neither form of radiation affected the expression of gp100, MART-1/MelanA, or S100.</p> <p>Conclusion</p> <p>These results indicate that UV-irradiation may increase the safety of autologous melanoma vaccines, although it may do so at the expense of altering the antigenic profile of the irradiated tumor cells.</p

Glacial deposits offer discrete snapshots of glacier extent but cannot provide the continuous records required for detailed interhemispheric comparisons. By contrast, lakes located within glaciated catchments can provide continuous archives of upstream glacial activity, but few such records extend beyond the last glacial cycle. Here a piston core from Lake Junín in the uppermost Amazon basin provides the first, to our knowledge, continuous, independently dated archive of tropical glaciation spanning 700,000 years. We find that tropical glaciers tracked changes in global ice volume and followed a clear approximately 100,000-year periodicity. An enhancement in the extent of tropical Andean glaciers relative to global ice volume occurred between 200,000 and 400,000 years ago, during sustained intervals of regionally elevated hydrologic balance that modified the regular approximately 23,000-year pacing of monsoon-driven precipitation. Millennial-scale variations in the extent of tropical Andean glaciers during the last glacial cycle were driven by variations in regional monsoon strength that were linked to temperature perturbations in Greenland ice cores1; these interhemispheric connections may have existed during previous glacial cycles.This research was supported by grants from the ICDP (02-2012) and from the US National Science Foundation (D.T.R., EAR-1402076; M.B.A., EAR-1404113; J.S.S., EAR-1400903; D.M., EAR-1404414; M.B., EAR-1402054).Peer reviewe

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Evaluating the Effect of Beauty on Labor Market Outcomes: A Review of the Literature.

An important underlying determinant of wage discrimination, as well as the gender wage gap is the way the labor market rewards individual physical attractiveness. This article surveys the extensive empirical literature of the effect of physical attractiveness on labor market outcomes. Particular attention is given to the channels through which attractiveness may affect individual labor market outcomes and the way attractiveness affects gender wage differentials. Further research is needed on the effect of attractiveness within occupations in order to provide more evidence on its productivity-enhancing channel of transmission and the effect this has on the gender wage gap

The Evolution of the Silver Hills Volcanic Center, and Revised 40Ar/39Ar Geochronology of Montserrat, Lesser Antilles, With Implications for Island Arc Volcanism

Studying the older volcanic centers on Montserrat, Centre Hills and Silver Hills, may reveal how volcanic activity can change over long time periods (≥1 Myr), and whether the recent activity at the Soufrière Hills is typical of volcanism throughout Montserrat's history. Here, we present the first detailed mapping of the Silver Hills, the oldest and arguably least studied volcanic center on Montserrat. Volcanism at the Silver Hills was dominated by episodic andesite lava dome growth and collapse, produced Vulcanian style eruptions, and experienced periodic sector collapse events, similar to the style of volcanic activity that has been documented for the Centre Hills and Soufrière Hills. We also present an updated geochronology of volcanism on Montserrat, by revising existing ages and obtaining new 40Ar/39Ar dates and palaeomagnetic ages from marine tephra layers. We show that the centers of the Silver, Centre, and Soufrière Hills were active during at least ∼2.17–1.03 Ma, ∼1.14–0.38 Ma, and ∼0.45 Ma–present, respectively. Combined with timings of volcanism on Basse-Terre, Guadeloupe these ages suggest that ∼0.5–1 Ma is a common lifespan for volcanic centers in the Lesser Antilles. These new dates identify a previously unrecognized overlap in activity between the different volcanic centers, which appears to be a common phenomenon in island arcs. We also identify an older stage of Soufrière Hills activity ∼450–290 ka characterized by the eruption of hornblende-orthopyroxene-phyric lavas, demonstrating that the petrology of the Soufrière Hills eruptive products has changed at least twice throughout the volcano's development
