- OBJECTIVE: One-hour plasma glucose (1-h PG) during the oral glucose tolerance test (OGTT) is an accurate predictor of type 2 diabetes. We performed a meta-analysis to determine the optimum cutoff of 1-h PG for detection of type 2 diabetes using 2-h PG as the gold standard. RESEARCH DESIGN AND METHODS: We included 15 studies with 35,551 participants from multiple ethnic groups (53.8% Caucasian) and 2,705 newly detected cases of diabetes based on 2-h PG during OGTT. We excluded cases identified only by elevated fasting plasma glucose and/or HbA1c. We determined the optimal 1-h PG threshold and its accuracy at this cutoff for detection of diabetes (2-h PG ≥11.1 mmol/L) using a mixed linear effects regression model with different weights to sensitivity/specificity (2/3, 1/2, and 1/3). RESULTS: Three cutoffs of 1-h PG, at 10.6 mmol/L, 11.6 mmol/L, and 12.5 mmol/L, had sensitivities of 0.95, 0.92, and 0.87 and specificities of 0.86, 0.91, and 0.94 at weights 2/3, 1/2, and 1/3, respectively. The cutoff of 11.6 mmol/L (95% CI 10.6, 12.6) had a sensitivity of 0.92 (0.87, 0.95), specificity of 0.91 (0.88, 0.93), area under the curve 0.939 (95% confidence region for sensitivity at a given specificity: 0.904, 0.946), and a positive predictive value of 45%. CONCLUSIONS: The 1-h PG of ≥11.6 mmol/L during OGTT has a good sensitivity and specificity for detecting type 2 diabetes. Prescreening with a diabetes-specific risk calculator to identify high-risk individuals is suggested to decrease the proportion of false-positive cases. Studies including other ethnic groups and assessing complication risk are warranted.

- BACKGROUND: Emergency Medical Services (EMS) is, by its nature, a challenging context that may create risks for both patients and employees. It is also known that an organisation's safety culture has an influence on both patient and employee safety. Finnish EMS organisations lack knowledge of how their safety culture is perceived by their employees.AIM: This study aims to test the psychometric properties of the Emergency Medical Services Safety Attitudes Questionnaire (EMS-SAQ) in a Finnish EMS setting. We also explore the connections between individual- and organisation-based characteristics and safety attitudes in the Finnish EMS.METHODS: A cross-sectional survey study design was used. The EMS-SAQ was used to collect data via social media. The instrument measures six domains of workplace safety culture: safety climate, teamwork climate, perceptions of management, job satisfaction, working conditions and stress recognition. The 5-point Likert scale was converted to a 100-point scale and mean ≥ 75 was dichotomized as a positive. Confirmatory factor analysis (CFA) was carried out to validate the EMS-SAQ in a Finnish setting. Other results were analysed by using non-parametric tests.RESULTS: 327 responses were included in the analysis. CFA showed that the total EMS-SAQ model had acceptable goodness-of-fit values in the Finnish EMS setting. Total mean scores for each safety culture domain were identified non-positively (mean score < 75); safety climate 60.12, teamwork climate 60.92, perceptions of management 56.31, stress recognition 64.55, working conditions 53.43 and job satisfaction 70.36. Higher education was connected to lower job satisfaction and the teamwork climate within the individual characteristics. All organisation-based characteristics caused at least one significant variation in the safety culture domain scores. Working area significantly affected (p < 0.05) five out of the six safety culture domain scores.CONCLUSIONS: The EMS-SAQ is a valid tool to evaluate safety culture among the Finnish EMS organisations; it offers a novel method to evaluate safety and patient safety within the Finnish EMS organisations. According to the findings, the organisation-based characteristics more likely had an impact on safety attitudes than did the individual-based characteristics. Therefore, it is suggested that the Finnish EMS organisations undertake safety culture development at the organisational level.
