Development of an Emergency Medicine Pharmacy Intensity Score Tool
Purpose
Emergency medicine pharmacists (EMPs) have been demonstrated to have a positive impact on patient outcomes in a variety of clinical scenarios in the emergency department (ED), yet their distribution across the nation is suboptimal. An emergency medicine pharmacy intensity score tool (EMPIST) would not only facilitate the quantification of EMP staffing needs and ideal resource deployment times, but would also allow practitioners to triage patient care activities. The purpose of this investigation was to develop an EMPIST and evaluate its relationship to EMP activities. Methods
This was a multicenter, prospective, observational analysis of an EMPIST developed by practicing EMPs. EMPs prospectively documented their clinical activities during usual care for patients in their ED. Spearman’s rank-order correlation was used to determine any correlation between the EMPIST and pharmacist activities. Results
In total, 970 EMP activities and 584 EMPIST items were documented in 352 patients by 7 EMPs across 7 different EDs. The most commonly documented EMP interventions performed were bedside monitoring (12.7%), initiation of nonantimicrobial therapy (12.6%), and antimicrobial therapy initiation and streamlining (10.6%). The total EMPIST was found to significantly correlate with EMP activities, and this correlation was consistent across both “diagnostic/presentation” and “medication” items (P \u3c 0.001 for all comparisons). Conclusion
The EMPIST significantly correlated with EMP activities, with consistent correlation across all subgroups. Its utilization has the potential to enhance bedside clinical practice and optimize the deployment of limited EMP services. Additional investigations are needed to examine the validity of this tool and identify any relationship it may have to patient outcomes
Improving the Description of Lateral Shower Profiles in the FoCal Detector Prototype
To get a better understanding of the fundamental laws and particles of the universe, a forward electromagnetic calorimeter (FoCal) is proposed for ALICE at CERN. A prototype detector has been build and is currently being analysed. This thesis focusses on finding an analytical description of the lateral hit density profiles of the prototype, obtained by measurements of the 50 GeV SPS beam at CERN. Unfortunatly, uncertainties of the hit densities from earlier analysis were lost and new uncertainties have been calculated, assuming pure Poisson fluctuations of the number of hits with a constant mean value per event. The new uncertainties are overestimated with the current approach, leading to difficulty in interpreting the fit results. From earlier analysis a power law function was deemed best fit for the profiles and in this thesis four adjustments are applied for new fits. The results are compared by looking at chisquare values of the fits. All adjusted functions seem to perform better than the original and the function, with added polynomial inside the power, performs best. Comparison between the results of the overestimated uncertainties and results obtained with underestimated uncertainties, shows similar behaviour of the fits. This could imply the functions are good to describe the data
Prevalence and risk factor analysis of resistant Escherichia coli urinary tract infections in the emergency department
BACKGROUND: Escherichia coli (E. coli) is a frequent uropathogen in urinary tract infections (UTI). Widespread resistance to sulfamethoxazole-trimethoprim (SMX-TMP) and increasing resistance to fluoroquinolones amongst these isolates has been recognized. There are limited data demonstrating risk factors for resistance to both SMX-TMP and fluoroquinolones. OBJECTIVE: This study was conducted to assess for the prevalence of community resistance amongst E. coli isolates to SMX-TMP and levofloxacin in ambulatory patients discharged from the emergency department (ED). METHODS: Adults presenting for evaluation and discharged from the ED with a diagnosis of an E. coli UTI were retrospectively reviewed. Utilizing demographic and clinical data the prevalence of E. coli resistance and risk factors associated with SMX-TMP- and fluoroquinolone-resistant infection were determined. RESULTS: Among the 222 patients, the mean rates of E. coli susceptibility to levofloxacin and SMX-TMP were 82.4% and 72.5%, respectively. Significant risk factors for resistance to SMX-TMP included prior antibiotic use (p=0.04) and prior diagnosis of UTI (p= 0.01). Significant risk factors for resistance to levofloxacin included: male gender, age, presence of hypertension, diabetes, chronic respiratory disease, nursing home resident, previous antibiotic use, previous diagnosis of UTI, existence of renal or genitourinary abnormalities, and prior surgical procedures (p <0.05 for all comparisons). The number of hospital days prior to initial ED evaluation (p<0.001) was determined to be a predictive factor in hospital and ED readmission. CONCLUSIONS: These results suggest that conventional approaches to monitoring for patterns of susceptibility may be inadequate. It is imperative that practitioners develop novel approaches to identifying patients with risk factors for resistance. Identification of risk factors from this evaluation should prompt providers to scrutinize the use of these agents in the setting of patients presenting with an uncomplicated UTI in the ED

ACUTE RELATIVE ADRENAL INSUFFICIENCY AFTER ANEURYSMAL SUBARACHNOID HEMORRHAGE
ABSTRACT OBJECTIVE The hypothalamic-pituitary-adrenal axis is an important part of the body's natural response to acute illness. Adrenal insufficiency has the potential to lead to hemodynamic instability and electrolyte imbalances, limit the body's ability to respond to stress, and worsen overall clinical outcome. In this case series, we describe 16 patients evaluated for acute adrenal insufficiency after aneurysmal subarachnoid hemorrhage. CLINICAL PRESENTATION Over a 2-year period, the medical records of 16 patients admitted to the adult neurosurgery service for aneurysmal subarachnoid hemorrhage who were nonresponsive to vasopressor therapy and received cosyntropin for the evaluation of adrenal insufficiency within 14 days of their event were reviewed. INTERVENTION The median baseline cortisol in this population was 22.5 ÎĽg/dL, with a poststimulation cortisol level of 31 ÎĽg/dL. Of the population surveyed, a total of 11 patients met the preestablished criteria for adrenal insufficiency, 3 with baseline cortisol levels of less than 15 ÎĽg/dL and 11 with poststimulation concentration changes of less than 9 ÎĽg/dL. Baseline serum cortisol concentrations were significantly correlated with hospital stay (P = 0.045), intensive care unit stay (P = 0.005), and ventilator days (P = 0.006). CONCLUSION To date, this is the only investigation evaluating the incidence of acute relative adrenal insufficiency in this population. In our cohort, 69% of the patients met the preestablished criteria for relative adrenal insufficiency. The impact of low-dose corticosteroid therapy in this population also needs review, as it could have significant implications for the management of cerebral vasospasm
