    ABSTRACT: BACKGROUND: This article reports on the impact assessment experience of a funding program of non-commercial clinical and health services research. The aim was to assess the level of implementation of results from a subgroup of research projects (on respiratory diseases), and to detect barriers (or facilitators) in the translation of new knowledge to informed decision-making. METHODS: A qualitative study was performed. The sample consisted of six projects on respiratory diseases funded by the Agency for Health Quality and Assessment of Catalonia between 1996 and 2004. Semi-structured interviews to key informants including researchers and healthcare decision-makers were carried out. Interviews were recorded, transcribed verbatim and analysed on an individual (key informant) and group (project) basis. In addition, the differences between achieved and expected impacts were described. RESULTS: Twenty-three semi-structured interviews were conducted. Most participants indicated changes in health services or clinical practice had resulted from research. The channels used to transfer new knowledge were mainly conventional ones, but also in less explicit ways, such as with the involvement of local scientific societies, or via debates and discussions with colleagues and local leaders. The barriers and facilitators identified were mostly organizational (in research management, and clinical and healthcare practice), although there were also some related to the nature of the research as well as personal factors. Both the expected and achieved impacts enabled the identification of the gaps between what is expected and what is truly achieved. CONCLUSIONS: In this study and according to key informants, the impact of these research projects on decision-making can be direct (the application of a finding or innovation) or indirect, contributing to a more complex change in clinical practice and healthcare organization, both having other contextual factors. The channels used to transfer this new knowledge to clinical practice are complex. Local scientific societies and the relationships between researchers and decision-makers can play a very important role. Specifically, the relationships between managers and research teams and the mutual knowledge of their activity have shown to be effective in applying research funding to practice and decision-making. Finally the facilitating factors and barriers identified by the respondents are closely related to the idiosyncrasy of the human relations between the different stakeholders involved.

    ABSTRACT: INTRODUCTION: The study aims to illustrate the impact of Spanish research in clinical decision making. To this end, we analysed the characteristics of the most significant Spanish publications cited in clinical practice guidelines (CPG) on mental health. MATERIAL AND METHODS: We conducted a descriptive qualitative study on the characteristics of ten articles cited in Spanish CPG on mental health, and selected for their "scientific quality". We analysed the content of the articles on the basis of the following characteristics: topics, study design, research centres, scientific and practical relevance, type of funding, and area or influence of the reference to the content of the guidelines. RESULTS: Among the noteworthy studies, some basic science studies, which have examined the establishment of genetic associations in the pathogenesis of mental illness are included, and others on the effectiveness of educational interventions. The content of those latter had more influence on the GPC, because they were cited in the summary of the scientific evidence or in the recommendations. Some of the outstanding features in the selected articles are the sophisticated designs (experimental or analytical), and the number of study centres, especially in international collaborations. Debate or refutation of previous findings on controversial issues may have also contributed to the extensive citation of work. CONCLUSIONS: The inclusion of studies in the CPG is not a sufficient condition of "quality", but their description can be instructive for the design of future research or publications.

    ABSTRACT: Objectives The goal of this study was to assess the risk associated with double antiplatelet therapy (DAT) discontinuation, and specifically, temporary discontinuation, during the first year after drug-eluting stent (DES) implantation. Background Doubts remain about the risk of temporary DAT discontinuation within 1 year after DES implantation. Methods A total of 1,622 consecutive patients undergoing DES implantation at 29 hospitals were followed up at 3, 6, 9, and 12 months to record the 1-year antiplatelet therapy discontinuation (ATD) rate, the number of days without DAT, and the rate of 1-year major cardiac events. Cox regression was used to analyze the association between ATD considered as a time-dependent covariate and 1-year cardiac events. Results One hundred seventy-two (10.6%) patients interrupted at least 1 antiplatelet drug during the first year after DES implantation, although only 1 during the first month. Most (n = 111, 64.5%) interrupted DAT temporarily (median: 7 days; range: 5 to 8.5): 79 clopidogrel (31 temporarily), 38 aspirin (27 temporarily), and 55 both drugs (53 temporarily). Discontinuation was followed by acute coronary syndrome in 7 (4.1%; 95% confidence interval [CI]: 1.7 to 8.2), a similar rate of major cardiac events to that in patients without ATD (n = 80; 5.5%; 95% CI: 4.4 to 6.8; p = 0.23). ATD was not independently associated with 1-year major cardiac events (hazard ratio: 1.32 [95% CI: 0.56 to 3.12]). Conclusions ATD within the first year and beyond the first month after DES is not exceptional, is usually temporary, and does not appear to have a large impact on risk.

    ABSTRACT: Aims: To determine the prevalence of aortic valve sclerosis (ASC) and stenosis (AS) in the elderly in a Mediterranean area and to identify associated clinical factors.Methods and Results: Population cross-sectional study in a random sample of 1068 people ≥65 years in a Mediterranean area. ASC was categorized as absent, mild-to-moderate, or moderate-to-severe depending on the severity of thickening and calcification. The relation between the severity of ASC and potential risk factors was assessed by multinomial logistic regression analysis. Some degree of thickening and/or calcification was present in 45.4%, of the sample, 73.5% in >85 years. AS prevalence was 3% for the total cohort and 7.4% in >85 years. Adjusting for gender it was found that age, smoking habit, hypertension, waist circumference, and ankle-brachial index <0.9 were associated with degrees of ASC. Except for waist circumference, there was a gradient between the magnitude of association and the severity of ASC. The OR for age was 1.56 (95% CI 1.39-1.76) for mild-to-moderate ASC and 2.03 (95% CI 1.72-2.4) for moderate-to-severe ASC, and for smoking habit 1.59 (95% CI 1.08-2.34) for mild-to-moderate ASC and 2.13 (95% CI 1.19-3.78) for moderate-to-severe ASC. Diabetes and renal impairment were associated with advanced but not with early stages of ASC.Conclusions: The prevalence of ASC and AS in people ≥65 years is similar to that reported in other regions. The gradient in the association of cardiovascular risk factors with the severity of ASC suggests that they may be causally implied in the pathogenesis of the disease.

    ABSTRACT: Patent false lumen in aortic dissection has been associated with poor prognosis. We aimed to assess the natural evolution of this condition and predictive factors. One hundred eighty-four consecutive patients, 108 surgically treated type A and 76 medically treated type B, were discharged after an acute aortic dissection with patent false lumen. Transesophageal echocardiography was performed before discharge, and computed tomography was performed at 3 months and yearly thereafter. Median follow-up was 6.42 years (quartile 1 to quartile 3: 3.31-10.49). Forty-nine patients died during follow-up (22 type A, 27 type B), 31 suddenly. Surgical or endovascular treatment was indicated in 10 type A and 25 type B cases. Survival free from sudden death and surgical-endovascular treatment was 0.90, 0.81, and 0.46 (95% CI, 0.36-0.55) at 3, 5, and 10 years, respectively. Multivariate analysis identified baseline maximum descending aorta diameter (hazard ratio [HR]: 1.32 [1.10-1.59]; P=0.003), proximal location (HR: 1.84 [1.06-3.19]; P=0.03), and entry tear size (HR: 1.13 [1.08-1.2]; P<0.001) as predictors of dissection-related adverse events, whereas mortality was predicted by baseline maximum descending aorta diameter (HR: 1.36 [1.08-1.70]; P=0.008), entry tear size (HR: 1.1 [1.04-1.16]; P=0.001), and Marfan syndrome (HR: 3.66 [1.65-8.13]; P=0.001). Aortic dissection with persistent patent false lumen carries a high risk of complications. In addition to Marfan syndrome and aorta diameter, a large entry tear located in the proximal part of the dissection identifies a high-risk subgroup of patients who may benefit from earlier and more aggressive therapy.

    ABSTRACT: To investigate the 30-day and 12-month mortality risks among hospitalized stroke patients according to compliance with guideline-based process indicators. We used data from the Second Stroke Audit and the Mortality Register of Catalonia (Spain). The audit retrospectively explored quality of stroke care based on compliance with indicators among patients discharged from all public hospitals in Catalonia in 2007; they were identified and selected through a pre-established sampling method. The magnitude of the independent association of each indicator with 30-day and 12-month mortality was assessed using logistic regression with generalized estimating equations to account for clustering of patients within hospitals. Generalized estimating equations modeling was initially restricted to patients alive >72 hours poststroke to control for confounding by severity. Analyses were also run in 3 other samples (all patients, patients alive >7 days, and patients alive >14 days). Of 1767 stroke admissions in the Second Stroke Audit, 1697 patients survived >72 hours poststroke. Within this sample, the adjusted 30-day mortality risk was negatively associated with nonadherence to different indicators, of which only antithrombotics at discharge (OR, 4.3; 95% CI, 1.72-10.78) remained significant in all data sets. At 12 months, the adjusted mortality risk was negatively associated with management of hypertension (OR, 1.87; 95% CI, 1.22-2.86) and antithrombotics at discharge (OR, 2.79; 95% CI, 1.41-5.54). Both remained unchanged across different samples. Assessing the impact of quality of stroke care on mortality is complex and is hampered by residual confounding, particularly in the short-term. Nevertheless, this study suggests that at least a few indicators should be used to monitor quality of stroke services.

    ABSTRACT: Advanced atherosclerotic disease increases the risk of stent thrombosis after drug-eluting stent (DES) implantation. We aimed to determine if an abnormal ankle-brachial index (ABI) value as a surrogate of atherosclerotic disease and vascular inflammation provides information on 1-year risk of cardiovascular events after DES implantation. A prospective cohort of 1,437 consecutive patients undergoing DES implantation from January through April 2008 in 26 Spanish hospitals was examined. ABI was calculated by Doppler in a standardized manner. Patients were followed to 12 months after the percutaneous coronary intervention to determine total and cardiovascular mortality, stroke, nonfatal acute coronary syndrome (ACS), and new revascularizations. Association of an abnormal ABI value (i.e., ≤ 0.9 or ≥ 1.4) with outcomes was assessed by conventional logistic regression and by propensity-score analysis. Patients with abnormal ABI values (n = 582, 40.5%) in general had higher global cardiovascular risk, the reason for DES implantation was more often ACS, and had a higher rate of complications during admission (heart failure or stroke or major hemorrhage 11.3% vs 5.3%, p <0.001). An abnormal ABI value was independently associated with 1-year total mortality (odds ratio 2.23, 95% confidence interval 1.13 to 4.4) and cardiovascular mortality (odds ratio 2.06, 95% confidence interval 1.04 to 4.22). No independent association was found between an abnormal ABI value and 1-year nonfatal ACS, stroke, and new revascularizations. In conclusion, although an abnormal ABI value was associated with fatal outcomes in patients receiving DESs, no association was found with nonfatal ACS and new revascularizations. A clear relation between abnormal ABI and surrogates of DES thrombosis could not be established.

    ABSTRACT: To determine whether mortality from acute myocardial infarction has reduced in Spain and the possibly related therapeutic factors. Nine thousand, nine hundred and forty-nine patients with ST-segment elevation myocardial infarction admitted to the Coronary Care Unit were identified from PRIAMHO I, II and MASCARA registries performed in 1995, 2000 and 2005, with a 6 month follow-up. From 1995 to 2005 patients were increasingly more likely to have hypertension, hyperlipidemia and anterior infarction, but age of onset and the proportion of females did not increase. Twenty-eight-day mortality rates were 12.6%, 12.3% and 6% in 1995, 2000 and 2005 respectively, and 15.3%, 14.6% and 9.4% at 6 months (both P-trend <.001). Multivariate analysis was performed and the adjusted odds ratio for 28-day mortality for an infarction occuring in 2005 (compared with 1995) was 0.62 (95% confidence interval: 0.44-0.88) whereas the adjusted hazard ratio for mortality at 6 months was 0.40 (95% confidence interval: 0.24-0.67). Other variables independently associated with lower mortality at 28 days were: reperfusion therapy, and the use of anti-thrombotic treatment, beta-blockers and angiotensin-converting enzyme inhibitors. The 28-day-6-month period had an independent protective effect on the following therapies: coronary reperfusion, and prescription of antiplatelet agents, beta-blockers and lipid lowering drugs upon discharge. Twenty-eight-day and six-month mortality rates fell among patients with ST-elevation myocardial infarction in Spain from 1995 to 2005. The possibly related therapeutic factors were the following: more frequent reperfusion therapy and increased use of anti-thrombotic drugs, beta-blockers, angiotensin-converting enzyme inhibitors and lipid lowering drugs.

    ABSTRACT: BACKGROUND: The use of drug-eluting stents (DES) is an example of the disparity between recommendations given by regulatory agencies and the real clinical world. Such disparity might lead cardiologists to adopt different routines in the use of DES. We aimed to assess variability of off-label DES use between hospitals and to what extent it can be explained by differences in patient or hospital characteristics. METHODS: Characteristics of consecutive patients receiving DES in 29 hospitals were recorded. Individual and hospital determinants of receiving DES for off-label indications were assessed by multilevel logistic regression. RESULTS: 1903 patients were recruited and 1188 (62.4%) received DES for off-label indications. Individual variables associated with off-label use were age (OR 1.01 (1-1.02)), previous percutaneous (OR 2.24 (1.68-2.97)) or surgical (2.41 (1.52-3.84)) revascularization, repeated procedure at the same admission (OR 4.66 (2.7-8.05)), receiving two (OR 4.17 (3.24-5.37)) or three or more DES (OR 14.12 (9.08-21.96)) vs one. Adjusting for individual variables, the Odds of receiving DES for off-label indication was higher in public funding hospitals with surgery availability vs private hospitals: 1.49 (0.86-2.6), and in public hospitals without surgery vs public with surgery availability: OR 1.76 (1.02-3.03). Interhospital variability reminded significant after adjustment for individual and contextual variables. CONCLUSION: Off-label DES use is highly variable between centers. Although this variability is partially determined by hospital type of funding and cardiac surgery availability, the substantial interhospital variability after multilevel adjustment suggests heterogeneity in the process of care.

    ABSTRACT: Different factors may weight on time from stroke onset to hospital arrival, and patients' alert certainly contributes to it. We sought to identify clinical and sociodemographic factors associated with a delayed alert and to delineate the profile of the potential latecomer in Catalonia (Spain). We used data from the Stroke Code (SC) registry that prospectively recruited consecutive patients with acute stroke, in whom SC was activated (SCA) or not (SCNA), admitted to all Catalan hospitals. Additionally, SCNA patients underwent a structured interview to explore additional beliefs and attitudes related to a delayed alert. We applied a 6-h cut-off to define alert delay according to the time limit for SC activation in Catalonia. We determined independent predictors of delay amongst clinical and sociodemographic data by multivariate logistic regression and applied sample weighting because of different study periods in the SCA and SCNA arms. Of the patients, 37.2% delayed alert beyond 6 h. Compared to non-delayers, latecomers were more likely diabetics, illiterates, belonged to an unfavored social class, and were living alone. Fewer had concomitant atrial fibrillation and alerted through emergency medical service (EMS)/112 whilst suffering a mild or moderate stroke. Amongst patients interviewed, being unaware of stroke's vascular nature and erroneously self-perceiving stroke as a reversible or irrelevant condition independently predicted a longer delay. Delaying alert after stroke shows a multifactorial background with implication of pre-stroke health status, socioeconomic factors, stroke-related features and patients' beliefs and attitudes toward the disease. In planning future educational campaigns, all these features should be considered.

    ABSTRACT: Although the GRACE risk scores (RS) are the preferred scoring system for risk stratification in acute coronary syndromes (ACS), little is known whether these RS still maintain their performance in the current era. We aimed to investigate this issue in a contemporary population with ACS. The study population composed of patients enrolled in the MASCARA national registry. The GRACE RS were calculated for each patient. Discrimination and calibration were evaluated with the C statistic and the Hosmer-Lemeshow test, in the whole population and according to the type of ACS, risk strata, and whether the patient had a history of diabetes and/or chronic renal failure. We determined if left ventricular ejection fraction (LVEF) provides incremental prognostic information above that established by the RS and whether percutaneous coronary intervention (PCI) during admission affects the performance of the score for predicting 6-month mortality. The 5,985 patients constituted the validation cohort for the in-hospital mortality RS and 5,635 the validation cohort for the 6-month mortality RS. Overall, both GRACE RS demonstrated excellent discrimination (C > 0.80) and calibration (all P values in Hosmer-Lemeshow >.1). Although similar results were seen in all subgroups, the 6-month mortality RS performed significantly less well in patients undergoing PCI compared to those patients who did not (C = 0.73 vs 0.76, P < .004). Adding LVEF to the RS did not convey significant prognostic information. The GRACE RS for predicting in-hospital and 6-month mortality still maintain their excellent performance in a contemporary cohort of patients with ACS. Further studies are needed to investigate the performance of the 6-month mortality GRACE score in patients undergoing in-hospital PCI. Left ventricular ejection fraction did not convey significant information over that provided by the RS.

    ABSTRACT: Predictors of antiplatelet therapy discontinuation (ATD) during the first year after drug-eluting stent implantation are poorly known. This was a prospective study with 3-, 6-, 9-, and 12-month follow-up of patients receiving at least 1 drug-eluting stent between January and April 2008 in 29 hospitals. Individual- and hospital-level predictors of ATD were assessed by hierarchical-multinomial regression analysis. ATD could be assessed in 1622 candidates for follow-up (82.5%). A total of 234 patients (14.4%) interrupted at least 1 antiplatelet therapy drug, predominantly clopidogrel (n=182, 11.8%). Bleeding events or invasive procedures led to ATD in 109 patients. This was predicted by renal impairment (odds ratio [OR] 2.81, 95% confidence interval [CI] 1.48 to 5.34), prior major hemorrhage (OR 3.77, 95% CI 1.41 to 10.03), and peripheral arterial disease (OR 1.78, 95% CI 1.01 to 3.15). Medical decisions led to ATD in 70 patients; this was predicted by long-term use of anticoagulant therapy (OR 3.88, 95% CI 1.26 to 11.98), undergoing the procedure in a private hospital (OR 13.3, 95% CI 1.69 to 105), and not receiving instructions about medication (OR 2.8, 95% CI 1.23 to 6.36). Thirty-nine patients interrupted ATD on their own initiative, mainly immigrants (OR 3.78, 95% CI 1.2 to 11.98) and consumers of psychotropic drugs (OR 2.58, 95% CI 1.3 to 5.12). ATD during the first year after drug-eluting stent implantation is based mainly on patient decision or a medical decision not associated with major bleeding events or major surgical procedures. Individual- and hospital-level variables are important to predict ATD.
