Abstract
BACKGROUND AND AIM There is a high prevalence in the Spanish general population of some cardiovascular risk factors like overweight, obesity and hypercholesterolaemia. But there is lack of research on Spanish seafarers. On the other hand, there is strong evidence of the cardiovascular risk predictive value of some biomarkers. The purpose of this work was to study the convenience of the introduction of detailed diet questionnaires and the measurement of some biomarkers in the pre-embarkation medical examination. MATERIALS AND METHODS Seafarers undergoing medical checkup during 2011 in Madrid, Spain (n = 334). Overweight and obese subjects received general advice on healthy diet and physical activity. Seventy-four of them were followed up in 2012 and 2013. Glycated haemoglobin (HbA1c), high-sensitivity C-reactive protein (hs-CRP), thyrotropin (TSH) and microalbuminuria were measured in two selected groups of patients in 2011. RESULTS Overweight and obesity were present in 207 (62%) individuals of the studied population. Those followed up in 2012 and 2013 showed a reduction of body mass index, waist circumference and total cholesterol values. We observed risk value of HbA1c in 60 (35.5%) individuals with significant association to other cardiovascular risk factors. Microalbuminuria appeared in subjects with high blood pressure. High TSH and hs-CRP were not significantly present in our population. CONCLUSIONS 1. Measurement of HbA1c during medical checkups improves early detection of cardiovascular risk in seafarers. 2. Individuals with overweight and obesity responded positively to medical advice and diminished their risk factors, thus it may be more effective to introduce detailed questionnaires on this issue.

Abstract
BACKGROUND Chinese medicine (CM) has its own diagnostic indicators that are used as evidence of change in a patient's condition. The majority of studies investigating efficacy of Chinese herbal medicine (CHM) have utilized biomedical diagnostic endpoints. For CM clinical diagnostic variables to be incorporated into clinical trial designs, there would need to be evidence that these diagnostic variables are reliable. Previous studies have indicated that the reliability of CM syndrome diagnosis is variable. Little information is known about where the variability stems from--the basic data collection level or the synthesis of diagnostic data, or both. No previous studies have investigated systematically the reliability of all four diagnostic methods used in the CM diagnostic process (Inquiry, Inspection, Auscultation/Olfaction, and Palpation). OBJECTIVES The objective of this study was to assess the inter-rater reliability of data collected using the four diagnostic methods of CM in Australian patients with knee osteoarthritis (OA), in order to investigate if CM variables could be used with confidence as diagnostic endpoints in a clinical trial investigating the efficacy of a CHM in treating OA. METHODS An inter-rater reliability study was conducted as a substudy of a clinical trial investigating the treatment of knee OA with Chinese herbal medicine. Two (2) experienced CM practitioners conducted a CM examination separately, within 2 hours of each other, in 40 participants. A CM assessment form was utilized to record the diagnostic data. Cohen's κ coefficient was used as a measure of the level of agreement between 2 practitioners. RESULTS There was a relatively good level of agreement for Inquiry and Auscultation variables, and, in general, a low level of agreement for (visual) Inspection and Palpation variables. CONCLUSIONS There was variation in the level of agreement between 2 practitioners on clinical information collected using the Four Diagnostic Methods of a CM examination. Some aspects of CM diagnosis appear to be reliable, while others are not. Based on these results, it was inappropriate to use CM diagnostic variables as diagnostic endpoints in the main study, which was an investigation of efficacy of CHM treatment of knee OA.

Abstract
CONTEXT Performance feedback and benchmarking, common tools for health care improvement, are rarely studied in randomized trials. Achievable Benchmarks of Care (ABCs) are standards of excellence attained by top performers in a peer group and are easily and reproducibly calculated from existing performance data. OBJECTIVE To evaluate the effectiveness of using achievable benchmarks to enhance typical physician performance feedback and improve care. DESIGN Group-randomized controlled trial conducted in December 1996, with follow-up through 1998. SETTING AND PARTICIPANTS Seventy community physicians and 2978 fee-for-service Medicare patients with diabetes mellitus who were part of the Ambulatory Care Quality Improvement Project in Alabama. INTERVENTION Physicians were randomly assigned to receive a multimodal improvement intervention, including chart review and physician-specific feedback (comparison group; n = 35) or an identical intervention plus achievable benchmark feedback (experimental group; n = 35). MAIN OUTCOME MEASURE Preintervention (1994-1995) to postintervention (1997-1998) changes in the proportion of patients receiving influenza vaccination; foot examination; and each of 3 blood tests measuring glucose control, cholesterol level, and triglyceride level, compared between the 2 groups. RESULTS The proportion of patients who received influenza vaccine improved from 40% to 58% in the experimental group (P<.001) vs from 40% to 46% in the comparison group (P =.02). Odds ratios (ORs) for patients of achievable benchmark physicians vs comparison physicians who received appropriate care after the intervention, adjusted for preintervention care and nesting of patients within physicians, were 1.57 (95% confidence interval [CI], 1.26-1.96) for influenza vaccination, 1.33 (95% CI, 1.05-1.69) for foot examination, and 1.33 (95% CI, 1.04-1.69) for long-term glucose control measurement. For serum cholesterol and triglycerides, the achievable benchmark effect was statistically significant only after additional adjustment for physician characteristics (OR, 1.40 [95% CI, 1.08-1.82] and OR, 1.40 [95% CI, 1.09-1.79], respectively). CONCLUSION Use of achievable benchmarks significantly enhances the effectiveness of physician performance feedback in the setting of a multimodal quality improvement intervention.
