ABSTRACT: The impact of psychological factors is often taken into account in the evaluation of quality of life. However, the effect of optimism and trait anxiety remains controversial and they are rarely studied simultaneously. We aimed to study the effect of this factor on health-related quality of life (HRQOL) of patients after a hospitalization in relation with their chronic disease. Using cross-sectional data from the SATISQOL cohort, we conducted a multicentric study, including patients hospitalized for an intervention in connection with their chronic disease. Six months after hospitalization, patients completed a generic HRQOL questionnaire (SF-36), and the STAI and LOT-R questionnaires to evaluate optimism and trait anxiety. We studied the effect of each trait on HRQOL separately, and simultaneously, taking account of their interaction in 3 models, using an ANOVA. In this study, 1529 patients were included in three participating hospitals and there existed wide diversity in the chronic diseases in our population. The HRQOL score increased for all dimensions of SF36 between 15,8 and 44,5 when the level of anxiety decreased (p < 0.0001) for the model 1, assessing the effect of anxiety on HRQOL and increased for all dimensions of SF36 between 3.1 and 12.7 with increasing level of optimism (<0.0001) in the model 2 assessing the effect of optimism on HRQOL. In the model 3, assessing the effect of both anxiety and optimism on HRQOL, and their interaction, the HRQOL score for all dimensions of the SF36 increased when the level of anxiety decreased (p < 0.0001). It increased with increasing level of optimism (p < 0.006) in the model for all dimensions of SF36 except the Role Physical dimension. In this model, interaction between anxiety and optimism was significant for the Social Functioning dimension (p = 0.0021). Optimism and trait anxiety appeared to be significantly correlated with HRQOL. Furthermore, an interaction existed between the trait anxiety and optimism for some dimensions of SF36. Contrary to optimism, it seems essential to evaluate trait anxiety in future studies about HRQOL, since it could represent a confounding factor.Health and Quality of Life Outcomes 08/2013; 11(1):134. · 2.10 Impact FactorThis article is viewable in ResearchGate's enriched formatRG Format enables you to read in context with side-by-side figures, citations, and feedback from experts in your field.

ABSTRACT: Prothrombin complex concentrate (PCC) for reversal of vitamin K antagonist (VKA) is the main therapeutic option in cases of life-threatening bleeding. Clinical use of PCC is poorly documented. We prospectively assessed PCC use in four French emergency departments during a two year period 2006-2008 before publication of French Guidelines. An appropriate treatment was defined when PCC was recommended, with a dose of PCC above or equal to 20 UI/kg, with vitamin K and with an assessment of international normalized ratio (INR) after PCC. Time of diagnosis and PCC administration were collected, as INR values, thromboembolic events within seven days, hospital mortality. 256 patients received PCC for reversal of OAT. PCC was mainly prescribed for major intracerebral (ICH) or gastrointestinal hemorrhage. An appropriate treatment was observed in 26% of patients. Intra-hospital mortality for major bleeding was 33% for ICH and 26% for non-ICH major bleeding. A PCC dose>20 UI/kg was able to reach an INR<1.5 in 65% of patients. For major hemorrhages (70%), time between patient arrival and treatment delivery exceeded three hours in half of cases. Control of INR was omitted in 20% of patients. No patients presented a thromboembolic event. A suitable treatment was administered in 26% of patients. A PCC dose of 20-30 IU/kg seems adequate in most cases to reverse VKA activity, but both higher and lower doses achieve similar effects. Considerable progress is required to improve PCC administration and control of treatment efficacy, and to shorten time to diagnosis.Thrombosis Research 06/2012; 130(3):e178-83. · 2.43 Impact Factor
