In Spain, one in four 14 to 18-year-old adolescents has used cannabis during the last twelve months. Demand for treatment has increased in European countries. These facts have prompted the development of preventive interventions that require screening tools in order to identify the vulnerable population and to properly asses the efficacy of such interventions. The Theory of Planned Behaviour (TPB), widely used to forecast behavioural intention, has also demonstrated a good predictive capacity in addictions. The aim of this study is to design and validate a Cannabis Use Intention Questionnaire (CUIQ) based on TPB. 1,011 teenagers answered a set of tests to assess attitude towards use, subjective norms, self-efficacy towards non-use, and intention to use cannabis. CUIQ had good psychometric properties. Structural Equation Modelling results confirm the predictive model on intention to use cannabis in the Spanish adolescent sample, classified as users and non-users, explaining 40% of variance of intention to consume. CUIQ is aimed at providing a better understanding of the psychological processes that lead to cannabis use and allowing the evaluation of programmes. This can be particularly useful for improving the design and implementation of selective prevention programmes.

An Integrated Healthcare Pathway (PAI) is a tool which has as its aim to increase the effectiveness of clinical performance through greater coordination and to ensure continuity of care. PAI places the patient as the central focus of the organisation of health services. It is defined as the set of activities carried out by the health care providers in order to increase the level of health and satisfaction of the population receiving services. The development of a PAI requires the analysis of the flow of activities, the inter-relationships between professionals and care teams, and patient expectations. The methodology for the development of a PAI is presented and discussed in this article, as well as the success factors for its definition and its effective implementation. It also explains, as an example, the recent PAI for Hypoglycaemia in patients with Type 2 Diabetes Mellitus developed by a multidisciplinary team and supported by several scientific societies., (Copyright © 2017 SECA.

Introduction and Objectives: Di@bet.es is a national study designed to estimate the prevalence of diabetes mellitus and other cardiovascular risk factors in the Spanish adult population. The prevalence of hypertension and the degree to which it is recognized, treated, and controlled are described., Methods: The study included a sample of the Spanish population with 5048 adults aged ≥ 18 years. Patients were questioned and examined, with 3 blood pressure readings while seated and at rest to calculate the mean of the 3 readings. Hypertension was defined as systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg and/or prescription for antihypertensive drug therapy., Results: Hypertension was found in 42.6% of the Spanish adult population aged ≥ 18 years and was more common among men (49.9%) than women (37.1%). The prevalence was higher among prediabetics (67.9%) and diabetics (79.4%). Undiagnosed hypertension was identified in 37.4% of patients and was more common in men (43.3%) than in women (31.5%). Among patients with known hypertension, 88.3% were receiving drug therapy. Well-controlled blood pressure was found in only 30% and was more common among women (24.9%) than men (16%)., Conclusions: The prevalence of hypertension in Spain is high, and a considerable percentage of hypertensive patients have still not been diagnosed. Hypertension is associated with diabetes and prediabetes, and although drug therapy is increasingly common, the degree of control has not improved and remains low. Population campaigns should be developed and promoted for hypertension prevention, detection, and treatment., (Copyright © 2016 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Background and Objective: The increase in the prevalence of type 2 diabetes mellitus (T2DM) is related to the increase of obesity. We aimed to determine the Spanish prevalence of T2DM in patients with overweight or obesity attended by either family or specialist physicians., Patients and Method: Cross-sectional, multicenter and simultaneous 2-phase design, performed under clinical conditions. Phase A was designed to determine T2DM prevalence: 169,023 patients were recruited. Phase B was designed to define socio-demographic, clinical and metabolic profile of T2DM according to the body mass index (BMI): 7,754 patients were included., Results: T2DM prevalence in overweight or obese patients was 23.6%; 17.8% of overweight patients were diabetic and T2DM was present in 34.8% of obese people. According to sex, 20.2% of men and 16.4% of women had T2DM. Overall, the mean of risk factors related to T2DM was 4.4 (SD 0,8); out of them, 92.6% patients had dyslipidemia, 73.7% hypertension and 62.5% performed a low physical activity. 37.8% of diabetic patients had vascular involvement. Only 43.1% of patients showed a proper metabolic control of T2DM (glycosilated hemoglobin<7%)., Conclusions: T2DM is related to overweight and obesity and higher the BMI is, higher the T2DM prevalence. Dyslipidemia, hypertension and a low physical activity in diabetic patients are more frequent when BMI increases. Patients with inadequate metabolic control have a higher BMI., (Copyright © 2012 Elsevier España, S.L. All rights reserved.)

Background and Objectives: A safety culture is essential to minimize errors and adverse events. Its measurement is needed to design activities in order to improve it. This paper describes the methods and main results of a study on safety climate in a nation-wide representative sample of public hospitals of the Spanish NHS., Material and Method: The Hospital Survey on Patient Safety Culture questionnaire was distributed to a random sample of health professionals in a representative sample of 24 hospitals, proportionally stratified by hospital size. Results are analyzed to provide a description of safety climate, its strengths and weaknesses. Differences by hospital size, type of health professional and service are analyzed using ANOVA., Results: A total of 2503 responses are analyzed (response rate: 40%, (93% from professionals with direct patient contact). A total of 50% gave patient safety a score from 6 to 8 (on a 10-point scale); 95% reported < 2 events last year. Dimensions "Teamwork within hospital units" (71.8 [1.8]) and "Supervisor/Manager expectations and actions promoting safety" (61.8 [1.7]) have the highest percentage of positive answers. "Staffing", "Teamwork across hospital units", "Overall perceptions of safety" and "Hospital management support for patient safety" could be identified as weaknesses. Significant differences by hospital size, type of professional and service suggest a generally more positive attitude in small hospitals and Pharmacy services, and a more negative one in physicians., Conclusions: Strengths and weaknesses of the safety climate in the hospitals of the Spanish NHS have been identified and they are used to design appropriate strategies for improvement.

Background and Objective: To assess the predictive value of some anthropometric parameters of central adiposity for the diagnosis of hyperglycemia and insulin resistance (IR) in the Spanish population., Patients and Method: Multicenter, cross-sectional study carried out in patients visited in primary care and in specialist clinics, of both sexes, between 18 and 79 years of age. IR was estimated in a subsample of patients by the Homeostasis Model Assessment (HOMA-IR). Patients with diagnosis of diabetes were excluded from the study., Results: A total of 3,638 patients were evaluated, 690 out of these participated in the IR substudy. Waist circumference (WC) was the parameter with a better correlation with hyperglycemia and with IR (r = 0.29 and 0.38; p < 0.001). Each increase of 15 cm in the WC was associated with an increase of the risk hyperglycemia and IR (65% and 123%, respectively). The cut-off points that better discriminated men and women, with and without IR, were 105 and 91 cm, with a sensitivity of 62% (95% confidence interval [CI], 46-77%) and 71% (95% CI, 54-85%), and a specificity of 72% (95% CI, 66-78%) and 68 (95% CI, 63-73%), respectively., Conclusions: WC is a useful anthropometric measure for the detection of hyperglycemia and IR, and the optimal cut-off points for the Spanish population from which IR could be detected are 105 cm for men and 91 for women.

Objective: To analyze the process of evaluating abstracts in the 2006 National Quality in Healthcare Conference in order to contribute to its continuous improvement, and to present its main scientific results., Design: descriptive study. 11 pairs of reviewers using explicit criteria evaluated abstracts., Population: all the abstracts received., Process: abstracts were accepted/rejected according to reviewers' concordant decisions. Disagreements were re-evaluated by 3 reviewers. Accepted abstracts were organized and distributed in the Conference according to the following criteria: total amount, available room and time, number of reviewers. The abstracts nominated for awards and which did not have discrepancies higher than 25 points were re-evaluated by all the reviewers. Their presentations in the Conference were also reviewed by a panel of judges created for this purpose, according to an evaluation guide., Results: 849 communications were received. Each reviewer evaluated a mean of 79 communications, obtaining an average score of 56 points. 762 communications were accepted (89.7%), 56.8% of them as a poster. Madrid (133) and Catalonia (124) had the highest amount of presentations in the Conference, but Cantabria and Murcia obtained the highest rates per million inhabitants., Conclusions: Despite the recently introduced changes, evaluating abstracts is a complex methodological process that still can be improved. It is conditioned by the need for limiting the extension of oral presentations and Conference time management. The scientific contribution to the Conference keeps rising. Its venue represents a geographic opportunity to encourage quality works., (Copyright © 2008 Sociedad Española de Calidad Asistencial. Published by Elsevier Espana. All rights reserved.)

Background and Objective: The PREVENCAT study was designed to estimate the control of the main cardiovascular risk factors (CVRF) and their treatment in a sample of population having the diagnoses of hypertension (HT), type 2 diabetes mellitus (DM2) or hypercholesterolemia (HC) who was attended by primary care physicians in Spain., Patients and Method: Cross-sectional study in patients with HT, DM2 and/or HC, who were consecutively recruited. We describe the treatments for HT, DM2 and HC and analyze and the association between several potential predictors and the control of these CVRF., Results: 2,649 patients were included in the study. 95% of HT patients were under treatment, as were 84% of DM2 and 71.4% of HC patients; most common drugs were diuretics, sulphonylureas and statins, respectively. Monotherapy was more frequent than combined therapy for hypertension treatment. The frequency of HT and DM2 treatment was similar among the subgroups defined by the presence or absence of the other two diagnoses. However, HC treatment was more common in the presence of DM2 (p = 0.001). Age, previous cardiovascular disease (CVD), DM2, obesity and sedentarism were all predictors of poor blood pressure control despite drug treatment. Age, previous CVD, HT and sedentarism were predictors of poor HC control., Conclusions: CVRF treatment was high although heterogeneous and not based on the best available evidence. DM2, previous CVD and obesity were associated with insufficient blood pressure control.

Background and Objective: We assess the metabolic control, complications, quality of life related to health (QLRH) and the type and amount of medical resource consumption (MRC) in type 2 diabetic patients (2DMp) followed by primary care physicians (PCP) in Spain., Patients and Method: We studied 628 2DMp divided in 4 cohorts: 1. Either newly diagnosed 2DMp who required pharmacological treatment or failed to non-pharmacological measures; 2. Patients pharmacologically treated for less than 1 year; 3. Patients with pharmacological treatment for more than 1 year; 4. Patients with impaired fasting glucose (control group)., Results: Eighty percent of the subjects were overweight. At baseline, 27.9, 23.5 and 36.9% of patients from cohorts 1, 2 and 3, respectively, had HbA1C < 8%. After 6 months of follow-up, 14.6, 21.3 and 22.8% of patients from cohorts 1, 2 and 3, respectively, still had "bad control". At baseline, 38.0%, 21.2% and 20.7% of patients from cohorts 1, 2, and 3, respectively, had "bad lipid profile". After 6 months, 57.4%, 54.2% and 45.3% of cohorts 1, 2 and 3, respectively, still had plasma cLDL levels > 130 mg/dl. Complications were more frequent in cohort 3. During the 6-month period, MRC was higher among 2DMp than controls (p < 0.05) and higher among patients from cohort 3 (p < 0.05) compared with all the other patients. More diabetic than control patients and more patients from cohort 3 than patients from cohort 1 and 2 reported that their expected quality of life would be better without diabetes., Conclusions: One out of four of diabetic patients studied had HbA1C and lipids higher than the limits suggested by guidelines. Type 2 diabetes is associated with higher MRC and worse QLRH. This situation is worse among long-term diabetic patients.

Unlabelled: INTRODUCTION AND OBJECTIVES. To study the significance of chest pain in the clinical practice of a Spanish hospital and to evaluate the impact of routine troponin determination., Methods: In our institution, routine serial measurements of troponins I and T were made in the evaluation of chest pain in 2000. We compared the results obtained in 1999 for all patients who visited the emergency room for chest pain and the patients who were hospitalized. We recorded the diagnosis at discharge, duration of the hospital stay, and associated costs., Results: In 2000, 1,820 patients with chest pain visited the emergency department, which was equivalent to 1.9% of visits and 7.5 cases per 1,000 people and year: 43% of these patients were hospitalized for suspected acute coronary syndrome as compared to 49% in 1999 (-12%; p > 0.001). Among the patients admitted, 28% were discharged with a diagnosis of non-ischemic chest pain. Troponin determinations were associated with a lower probability of admission due to unstable angina (11.5 vs 16.0%; -28%; p < 0.001) and non-ischemic chest pain (12.1 vs 14.5%; -16%; p < 0.05), and an increase in diagnoses of non-Q wave acute myocardial infarction (3.4% vs 1.8%; +89%; p < 0.01). Non-ST elevation acute coronary syndrome ACS required 3,751 days of hospitalization and 1,003,420 euros of cost, and troponin determinations were associated with a reduction in hospital stays of 832 days (-18.2%) and 185,100 euros (-15.6%)., Conclusion: Chest pain had a high incidence, 7.5, and generates high costs in hospital admissions. The routine use of serial troponin determinations was associated with a reduction in hospital admissions due to unstable angina and non-ischemic chest pain, and costs.

Background: Moderately increased plasma homocysteine (Hcy) in children has been associated with stroke and venous thrombosis and with a parental history of cardiovascular disease (CVD). Evaluation of Hcy concentrations during childhood and study of the factors determining its concentrations could play an important role in the primary prevention of CVD. Objective To detect cases of hyperhomocystinemia and to examine the association between Hcy levels and plasma folic acid levels and 677C T polymorphism of 5,10-methylenetetrahydrofolate reductase (MTHFR)., Methods: The relationship between plasma Hcy levels, plasma folic acid levels, and the three genotypes of 677C T MTHFR polymorphism was investigated in 127 children (aged 2-18 years) and in 105 parents by multiple linear regression., Results: The median Hcy levels were 5.00 mol/l in the children and 8.00 mol/l in the parents. Plasma folic acid levels were normal in all of the patients. The prevalence of the three genotypes in the children was 32.3 % for the CC genotype, 42.5 % for the CT genotype and 15.7 % for the TT genotype. Hcy concentrations were significantly higher in children with the TT genotype (p 0.018). Multiple linear regression revealed a positive direct effect of age (b 0.029, p 0.002) and a negative effect of genotype TT (b 3.886, p 0.002) on Hcy concentration. Hcy concentration was inversely correlated with folic acid levels but this correlation did not reach statistical significance., Conclusions: No cases of hyperhomocystinemia were found. To evaluate Hcy, age and plasma folic acid levels have to be taken into account in case there is a 677C T mutation. Hcy concentrations should be determined in older children with a family history of atherothrombosis and other risk factors for premature CVD.

Background: Type 2 diabetes mellitus (DM 2) constitutes today one of the most important problems in terms of health. Nowadays, there is special interest to identify those subjects with a high risk for developing the disease. Our study aimed to evaluate fasting glycemia and glycated hemoglobin in the screening of defects in oral glucose tolerance, in relatives of patients with DM 2., Subjects and Methods: 111 relatives of patients with DM 2 were consecutively included in the study. Glycated hemoglobin (HbA1c, DCA 2000) was measured, afterwards an oral glucose tolerance test (OGTT) was performed. 120 min glycemia (G120) classified oral glucose tolerance as: normal (NGT), impaired glucose tolerance (IGT) and DM. In a first subgroup (n = 80) the equation to predict G120 was obtained (G120 estimated) from the basal glycemia (GO) and HbA1c. In a second subgroup (n = 31), G120 observed after the OGTT (G120 observed) and G120 estimated were compared. Finally, sensitivity, specificity and positive predictive value (PPV) for different cutpoints of GO and G120 were estimated, in order to identify those subjects with abnormal glucose tolerance (IGT and DM)., Results: Considering the results from the first subgroup of subjects, G120 was independently related with GO (R2 = 0.64) and with HbA1c (R2 = 0.62). When GO and HbA1c were considered altogether R2 value was 0.73. When data from the second subgroup of subjects was analysed we did not find any differences between observed G120 and G120 estimated by the equation. The sensitivity, specificity and PPV to detect abnormalities in oral glucose tolerance of estimated G120 were 80, 76 and 61%, respectively. Optimal values of these parameters were obtained with GO 98-102 mg/dl and Hba1c 5.6-5.8%., Conclusions: Our results confirm that the measurement of GO and HbA1c in first degree relatives of patients with DM 2 is extremely useful to identify those subjects in which abnormal oral glucose tolerance is highly probable.

Background: The aim of this study was to analyze the predictive factors of IDDM in first degree relatives of IDDM patients., Subjects and Methods: From 1992 to 1994, 1,053 first degree relatives were screened for measuring islet cell antibodies (ICA) by indirect immunofluorescence (iFl). In all ICA positive subjects, beta cell function was analyzed by intravenous glucose tolerance test (IVGTT) and other immunologic parameters were also studied: anti-insulin antibodies (IAA) by radiobinding and antibodies to glutamic acid decarboxylase (GADAb) by ELISA methods., Results: ICA were found in 3.1% of the first degree relatives. IVGTT showed a significant decrease in acute first phase of insulin response to glucose (IRI 1 minute + 3 minute) in those with ICA > or = 20 JDF units. In patients with ICA > or = 20 JDF units, 20% were found to be positive for IAA and 40% were positive for GAdAb. Thirty-one percent (10/32) of ICA positive first degree relatives fulfilled prediabetes criteria. During follow-up, 40% (4/10) of these prediabetic patients developed IDDM., Conclusion: This study confirms the possibility of identifying among first degree relatives of IDDM patients the subgroup with high risk of developing IDDM thus allowing the initiation of therapy for preventing or delaying IDDM onset.

To evaluate the role of metabolic control at the beginning of insulin-dependent diabetes mellitus (IDDM) in the development of diabetic retinopathy (DR) a cross-sectional study was performed with a retrospective analysis of 24 patients followed for at least seven years. The following parameters were investigated: 1) At IDDM diagnosis, age, sex, metabolic control (basal serum glucose, HbA1, cholesterol, triglycerides) and endogen insulin secretion (EIS). 2) At one year in the follow-up: EIS. 3) Since IDDM diagnosis and every 3-4 months: body mass index, dose and pattern of insulin administration and metabolic control. 4) At seven years in the follow-up: direct ophthalmoscopy, fluorescein angiography, microalbuminuria and blood pressure. In the seventh year of follow-up five patients (23.8%; 95% CI: 8.2%-47.2%) developed changes in fluorescein angiography secondary to IDDM. Compared with patients with normal fluorescein angiography their metabolic control was poorer (mean HbA1--seven years--: 11.7 +/- 0.5 versus 9.8 +/- 0.3%; p = 0.01); mean basal glycemia--seven years--: 214 +/- 13.3 versus 174 +/- 7.7 mg/dl; p = 0.03) and their systolic blood pressure (SBP) higher (124 +/- 5.5 versus 111 +/- 2.8 mmHg; p = 0.04). Logistic regression revealed that mean HbA1 values for seven years was the only independent risk factor significantly associated with the development of DR (p = 0.04). The conclusion is that in patients with IDDM of short duration, the development of DR is associated with a deficient glucose control and a higher SBP.

Background: Insulin treatment in patients with type-II diabetes mellitus (DMII) is normally undertaken by clinical criteria. The aim of the present was to study the efficacy of a standard mixed meal (breakfast test) to predict the need for insulin therapy to thereby evaluate whether it is possible to obtain more objective criteria for the indication of insulin treatment., Methods: Fifty-six patients with DMII were studied to evaluate the need for insulin therapy over a one-year period. Serum glucose and basal C peptide and their maximum values were determined in all the patients following stimulation with the breakfast test. Insulin treatment was initiated according to exclusively clinical criteria during admission. The patients were followed as out patients for a minimum of 3 months. Treatment at the end of follow up (insulin or no insulin) was evaluated and the results of the test were retrospectively analyzed., Results: The basal C peptide (BCP) values were significantly lower in the individuals requiring insulin in comparison to those who did not require insulin (mean +/- SD 0.64 +/- 0.28 versus 1.18 +/- 0.41 nmol/l, p < 0.0001) similar to what was found with the stimulated maximum C peptide values (MCP) (1.48 +/- 0.77 versus 2.49 +/- 0.63 nmol/l, p < 0.0001). On considering a BCP of less than 0.9 nmol/l for the patients with insulin treatment the sensitivity of BCP was 83.6% and the specificity 78.9%. For a BCP value of less than 1.9 nmol/l sensitivity was 77.7% and specificity 78.9%. Using the values together, sensitivity was 66.6% and specificity 84.4%., Conclusions: The breakfast test is useful to indicate the need for insulin therapy in patients with type II diabetes mellitus but is not more useful than a determination of isolated basal C peptide.

A series of 12 patients with digestive symptoms, pointing to gastroparesia, were studied. An attempt was made to correlate the symptoms and their intensity with the quantitative measurement of the mean time of evacuation of solids. No correlation was found between the intensity of the symptoms and the evacuation of solids. The sensitivity of the symptoms or their combinations is only 63%. Their specificity was not determined in this phase of the study. It is concluded that it is necessary to perform the quantitative study of evacuation of solids to confirm the presence of gastroparesia.

Five obese patients were studied during 7 days, 750 mg of tolbutamide, per os, was given. Blood samples were drawn at basal state and at 3, 5, 7 days during the treatment and 6 days after it. The values of transglutaminase activity (that in the basal state were similar to that in the controls) decreased significantly at the seventh day of treatment (72.3%). This decrease was transient and rapidly returned to the basal values when the drug was suspended. The results suggest that sulfonylureas exert in part their hypoglucemic effect by modificating the insulin receptor binding through the inhibition of transglutaminase activity.

Glycosylated hemoglobin ((HbA1c) is formed by structural modification of HbA in a slow and irreversible non-enzymatic reaction. Its concentration is proportional to mean blood glucose levels during approximately four weeks, being therefore a useful index of diabetes mellitus control. The introduction of a microcolumn chromatographic method that measures together the subfractions HbA1a + b + c (fast Hb) and is well correlated to HbA1c has permitted the routine clinical measurement of this parameter. The authors used this method to study the levels of glycosylated hemoglobin in normal subjects, acutely decompensated diabetics, and diabetic outpatients classified according to their degree of control. The highest levels were detected in acutely decompensated patients and in those with chronic poor compensation. It is concluded that HbA1 constitutes a good index of compensation in diabetes, and that it may in the future unify existing criteria on the disease, contributing to clarify the problems about the correlation between the degree of compensation of diabetes and the incidence and evolution of its specific complications.
