Objective: To identify a risk profile for harmful medication errors in the neonatal intensive care unit (NICU).Study Design: A retrospective cross-sectional study on NICU medication error reports submitted to MEDMARX between 1 January 1999, and 31 December 2005. The Rao-Scott modified w 2 test was used for analysis.Result: 6749 NICU medication error reports were submitted by 163 health-care facilities. Administering errors accounted for approximately one half of errors, and human factors were the most frequently cited cause of error. Patient age was not associated with an increased likelihood of an error being harmful (P ¼ 0.11). Error reports involving Institute for Safe Medication Practices (ISMP) High-Alert Medications, occurring in the prescribing phase of medication processing, or involving equipment/ delivery device failures were more likely to be harmful (Pp0.05). Conclusion:Risk factors for harmful medication error reports include use of ISMP High-Alert Medications, the prescribing phase of the medication use process, and failure of equipment/delivery devices.

“…The 0.1/1.0 and 0.01/1.0 mm protocols were judged equally effective for EMAP purposes if, after linear scale transformation of the 0.01/1.0 data, the S, A, and H CDFs for the two protocols were not significantly different [F-based Wald test (Thomas et al, 1996); α = 0.05]. Similarly, the 0.01/1.0 and 0.01/0.5 protocols were judged equally effective for EMAP purposes if, after linear scale transformation of the 0.01/0.5 data, the S, A, and H CDFs for the two protocols were not significantly different (F-based Wald test; α = 0.05).…”

Benthic macrofaunal sampling protocols in the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP) are to collect 30 to 50 random benthic macrofauna [defined as animals retained on a 0.5 mm (East and Gulf Coasts, USA) or a 1.0 mm mesh sieve (West Coast, USA)] samples per reporting unit using a 0.044 m(2) (East and Gulf Coasts) or 0.1 m(2) (West Coast) grab. Benthic macrofaunal community conditions in the reporting unit are characterized by cumulative distribution functions (CDFs) on end points of interest, such as number of species (S), abundance (A), and Shannon-Wiener diversity (H'). An EMAP and a companion field study were conducted concurrently in Tillamook Bay (Oregon, USA) to compare the cost effectiveness of benthic macrofauna samples collected using the EMAP West Coast (0.1 m(2) x >or=7 cm deep, 1.0 mm mesh), a 0.01 m(2) x 5 cm deep, 1.0 mm mesh, and a 0.01 m(2) x 5 cm deep, 0.5 mm mesh sampling protocol. Cost was estimated in relative laboratory sample-processing time. Sampling protocols were judged equally effective for EMAP purposes if, after linear transformation to adjust for scale changes in end point distributions, their S, A, and H' CDFs were not significantly different. The 0.01 m(2) x 5 cm deep, 1.0 mm mesh sampling protocol was the most cost effective.

“…The statistical analyses were done using Excel version 2010, SPSS version 13.0 (IBM, NY, USA) and SAS version 9.3 (SAS Institute Inc., Cary, NC, USA). The Rao-Scott Chi-Square Test was run to ascertain statistical differences between categorical variables (categories of coffee intake with sex, age, years of education, marital status, alcohol and supplement use, cigarette smoking, physical activity practised, body mass index -BMI classes) and was also used to compare the prevalence of coffee consumption obtained by the 2008-2009 Household Budget Survey (HBS) (Thomas et al, 1996; Instituto Brasileiro de Geografia e Estatística, 2011).…”

Personal characteristics of coffee consumers and non-consumers, reasons and preferences for foods eaten with coffee among adults from the Federal District, Brazil

The aim of this study is to describe the characteristics of consumers and non-consumers, the reasons and foods associated with coffee intake among adults from the Federal District, Brazil. This is a cross-sectional population-based survey conducted by telephone interview (n= 1,368). We collected information on detailed coffee intake, socio-demographic aspects and personal characteristics. The coffee had an average daily intake of 319 mL. Individuals were more likely to drink coffee at an older age (68%) and with higher body mass index (58%). The most cited reason for consuming coffee was the "personal pleasure" (48%), followed by "habit / tradition" of consuming coffee. Among non-consumers of this beverage, the main reason was not liking the taste and / or aroma of coffee (62%). The method of coffee preparation used was by infusion (86%) and sugar was the main sweetener used by 83% of consumers. The majority of consumers (59%) reported consuming coffee with certain foods such as bakery products. The results from our study may suggest that the popularity of coffee can be attributed to its taste, personal pleasure and habit, and the consumption is more likely to occur with the advance of age and with intake of other foods.Keywords: coffee; consumption; Brazilians; taste; beverage.Pratical Application: Dur study permitted evaluation of personal characteristics of coffee consumers and non-consumers, different methods of coffee preparation, including caffeinated, decaffeinated, filtered and non-filtered, as well as the choice, reasons and preferences for foods eaten with coffee. Given that the potential interest of our results is from Brazilian readers and the increase interest of the functional properties of coffee there are potential for citations and downloads from the scientific community, regulatory agencies, industry, and public health professionals.
