RESUMO
Bladder cancer (BC) is an important cause of premature mortality (PM, <75 years). Spain has one of the highest BC mortality rates in Europe. The objective of this study was to analyse BC mortality trends between 1999 and 2018 in Spain. The study was based on data from the National Institute of Statistics (Instituto Nacional de Estadística-INE). Age-adjusted mortality rates (AAMRs) were calculated by sex and age group. A trend analysis was performed using Joinpoint regression models and years of potential life lost (YPLL). Mortality in men resulting from BC decreased in all age groups studied. This was not observed in women, for whom mortality only decreased in the ≥75 age group. Deaths due to BC occurred prematurely in 38.6% of men and in 23.8% of women, which indicated a greater impact on YPLL in men compared to women. Over the last 20 years, there has been a significant decrease in BC mortality rate, except in women under 75 years of age. Despite this temporal trend of decreasing mortality, BC continues to have a significant impact on YPLL, mainly in men. Given this context, it is important to direct more resources towards prevention and early diagnosis strategies to correct this situation.
RESUMO
BACKGROUND: Pharmacological non-adherence in chronic diseases is 40-65%. No predictive profile of non-adherence exists in patients with multiple chronic diseases. Our study aimed to quantify the prevalence of non-adherence to pharmacological treatment and its associated factors in patients who visit pharmacies in Spain. METHODS: This observational cross-sectional study included patients with one or more chronic diseases. The variables analyzed were demographics, diseases involved, self-medication, information about disease, and lifestyle. The main variable was adherence using the Morisky-Green test. A total of 132 pharmacies collaborated, providing 6327 patients representing all Spain regions (April-December 2016). Bivariate and multivariate analyses were performed and the area under the receiver operating characteristic (ROC) curve was calculated. RESULTS: Non-adherence was 48.4% (95% confidence interval (CI): 47.2-49.7%). The variables that reached significance in the multivariate model were: difficulty in taking medication, self-medication, desire for more information, smoking, lower physical activity, younger age and number of chronic treatments. Discrimination was satisfactory (area under the ROC curve = 70%). Our study found that 50% patients was non-adherent and we obtained a profile of variables associated with therapeutic non-adherence. CONCLUSIONS: It is cause for concern that in patients with multiple diseases and taking multiple medications, there is an association between non-adherence, self-medication and worse lifestyle.

In hysterectomized patients, even though there is still controversy, evidence indicates that in the short term, the vaginal approach shows benefits over the laparoscopic approach, as it is less invasive, faster and less costly. However, the quality of sexual life has not been systematically reviewed in terms of the approach adopted. Through a systematic review, we analyzed (CRD42020158465 in PROSPERO) the impact of hysterectomy on sexual quality and whether there are differences according to the surgical procedure (abdominal or vaginal) for noncancer patients. MEDLINE (through PubMed), Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and Scopus were reviewed to find randomized clinical trials assessing sexuality in noncancer patients undergoing total hysterectomy, comparing vaginal and abdominal (laparoscopic and/or open) surgery. Three studies that assessed the issue under study were finally included. Two of these had a low risk of bias (Cochrane risk of bias tool); one was unclear. There was significant variability in how sexuality was measured, with no differences between the two approaches considered in the review. In conclusion, no evidence was found to support one procedure (abdominal or vaginal) over another for non-oncological hysterectomized patients regarding benefits in terms of sexuality.

PURPOSE: Of the different modalities of rowing, dragon boat training is the most analyzed in breast cancer (BC). However, other types of boats, such as the felucca, use different biomechanical techniques, which have not been studied in the scientific literature. Consequently, in this study, we sought to determine the benefits of felucca rowing on the physical, psychological, and emotional well-being of patients with BC and healthy persons. METHODS: A pre- and post-intervention, single-arm study without a control group with a 4-month intervention was carried out in Spain in 2019. The study sample included six women with BC and 15 healthy women. The following questionnaires were administered before and after the intervention: Disabilities of the Arm, Shoulder, and Hand (DASH), Constant-Murley score (CMS), and the European Quality of Life 5 Dimensions (EQ-5D, rate your health today). Differences were determined before and after the intervention using the paired t test. RESULTS: Significant differences (p < 0.05) were found in the results of all the questionnaires for the women with BC and for the healthy women: DASH (- 13.8 BC and - 6.7 healthy), CMS (+ 12.0 BC and 9.2 healthy), and EQ-5D (+ 8.5 BC and 10.5 healthy). CONCLUSION: Felucca rowing showed benefits in health and quality of life in both women with BC and healthy women. In future studies with controlled design, values regarding clinical relevance, such as effect sizes/confidence intervals, are needed to corroborate our results.

BACKGROUND: Clustering of cardiovascular risk factors (CVRFs) is extraordinarily common and is associated with an increased risk of cardiovascular disease (CVD). However, the particular impact of the sum of CVRFs on cardiovascular morbidity and mortality has not been sufficiently explored in Europe. OBJECTIVE: The aim of this study was to analyze the differences in survival-free probability of CVD in relation to the number of CVRFs in a Spanish population. METHODS: A prospective cohort study was conducted from 1992 to 2016 in a Spanish population that included 1144 subjects with no history of CVD (mean age, 46.7 years) drawn from the general population. We calculated the number of CVRFs for each subject (male sex, smoking, diabetes, hypertension, dyslipidemia, obesity, and left ventricular hypertrophy). Cardiovascular morbidity and mortality records were collected, and survival analysis was applied (competing risk models). RESULTS: There were 196 cardiovascular events (17.1%). The differences in total survival-free probability of cardiovascular morbidity and mortality of the different values of the sum of CVRFs were significant, increasing the risk of CVD (hazard ratio, 1.30; 95% confidence interval, 1.13-1.50) per each additional risk factor. CONCLUSION: Differences in survival-free probability of CVD in relation to the number of CVRFs present were statistically significant. Further studies are needed to corroborate our results.

BACKGROUND: The main instruments used to assess frailty are the Fried frailty phenotype and the Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight (FRAIL) scale. Both instruments contain items that must be obtained in a personal interview and cannot be used with an electronic medical record only. AIM: To develop and internally validate a prediction model, based on a points system and integrated in an application (app) for Android, to predict frailty using only variables taken from a patient's clinical history. DESIGN AND SETTING: A cross-sectional observational study undertaken across the Valencian Community, Spain. METHOD: A sample of 621 older patients was analysed from January 2017 to May 2018. The main variable was frailty measured using the FRAIL scale. Candidate predictors were: sex, age, comorbidities, or clinical situations that could affect daily life, polypharmacy, and hospital admission in the last year. A total of 3472 logistic regression models were estimated. The model with the largest area under the receiver operating characteristic curve (AUC) was selected and adapted to the points system. This system was validated by bootstrapping, determining discrimination (AUC), and calibration (smooth calibration). RESULTS: A total of 126 (20.3%) older people were identified as being frail. The points system had an AUC of 0.78 and included as predictors: sex, age, polypharmacy, hospital admission in the last year, and diabetes. Calibration was satisfactory. CONCLUSION: A points system was developed to predict frailty in older people using parameters that are easy to obtain and recorded in the clinical history. Future research should be carried out to externally validate the constructed model.

INTRODUCTION: Predictive models must meet clinical/methodological standards to be used in clinical practice. However, no critique of those models relating to mortality/recurrence in tongue cancer has been done bearing in mind the accepted standards. METHODS: We conducted a systematic review evaluating the methodology and clinical applicability of predictive models for mortality/recurrence in tongue cancer published in MEDLINE and Scopus. For each model, we analysed (domains of CHARMS, Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies) the following: source of data, participants, outcome to be predicted, candidate predictors, sample size, missing data, model development, model performance, model evaluation, results and interpretation and discussion. RESULTS: We found two papers that included eight prediction models, neither of which adhered to the CHARMS recommendations. CONCLUSION: Given the quality of tongue cancer models, new studies following current consensus are needed to develop predictive tools applicable in clinical practice.

Objective As very few studies have assessed therapeutic inertia (TI) in anti-platelet therapy in patients in secondary cardiovascular prevention, the authors designed a study in their hospital emergency department to quantify its magnitude and its associated factors. Methods This descriptive cross-sectional observational study involved a sample of 223 patients with a history of cardiovascular disease and recommendation for anti-platelet therapy who attended the emergency department in a Spanish region in 2016. The main variable was TI in platelet anti-aggregation (lack of a prescription when recommended by the clinical guidelines). The secondary variables were gender, age, educational level, stable partner, hypertension, dyslipidemia, diabetes, smoking, type and number of cardiovascular events, blood pressure, and glomerular filtration rate. The magnitude of TI was quantified and associated factors were studied using a binary logistic regression model. Results TI was present in 107 patients (48.0%). In the multifactorial analysis, the following factors were associated with a higher proportion of TI: female gender (p = .021), higher cultural level (p = .020), and having no previous diagnosis of hypertension (p = .003) or dyslipidemia (p = .002). Conclusions The magnitude of TI in anti-platelet therapy in patients who had already suffered a cardiovascular event was very high. TI was associated with being a woman, having a high cultural level, and not being diagnosed with hypertension or dyslipidemia. More studies are needed to corroborate these results to take the appropriate measures to reduce TI.

The aim of this study was to construct and internally validate a scoring system to estimate the probability of death in hypertensive inpatients. Existing predictive models do not meet all the indications for clinical application because they were constructed in patients enrolled in clinical trials and did not use the recommended statistical methodology. This cohort study comprised 302 hypertensive patients hospitalized between 2015 and 2017 in Spain. The main variable was time-to-death (all-cause mortality). Secondary variables (potential predictors of the model) were: age, gender, smoking, blood pressure, Charlson Comorbidity Index (CCI), physical activity, diet and quality of life. A Cox model was constructed and adapted to a points system to predict mortality one year from admission. The model was internally validated by bootstrapping, assessing both discrimination and calibration. The system was integrated into a mobile application for Android. During the study, 63 patients died (20.9%). The points system prognostic variables were: gender, CCI, personal care and daily activities. Internal validation showed good discrimination (mean C statistic of 0.76) and calibration (observed probabilities adjusted to predicted probabilities). In conclusion, a points system was developed to determine the one-year mortality risk for hypertensive inpatients. This system is very simple to use and has been internally validated. Clinically, we could monitor more closely those patients with a higher risk of mortality to improve their prognosis and quality of life. However, the system must be externally validated to be applied in other geographic areas.

OBJECTIVE: Current breast cancer recurrence prediction models have limitations for clinical practice (statistical methodology, simplicity and specific populations). We therefore developed a new model that overcomes these limitations. METHODS: This cohort study comprised 272 patients with breast cancer followed between 2003 and 2016. The main variable was time-to-recurrence (locoregional and/or metastasis) and secondary variables were its risk factors: age, postmenopause, grade, oestrogen receptor, progesterone receptor, c-erbB2 status, stage, multicentricity, diagnosis and treatment. A Cox model to predict recurrence was estimated with the secondary variables, and this was adapted to a points system to predict risk at 5 and 10 years from diagnosis. The model was validated internally by bootstrapping, calculating the C statistic and smooth calibration (splines). The system was integrated into a mobile application for Android. RESULTS: Of the 272 patients with breast cancer, 47 (17.3%) developed recurrence in a mean time of 8.6⯱â¯3.5 years. The system variables were: age, grade, multicentricity and stage. Validation by bootstrapping showed good discrimination and calibration. CONCLUSIONS: A points system has been developed to predict breast cancer recurrence at 5 and 10 years.

No validated screening method currently exists for Chronic Obstructive Pulmonary Disease (COPD) in smokers. Therefore, we constructed a predictive model with simple parameters that can be applied for COPD screening to detect fixed airflow limitation. This observational cross-sectional study included a random sample of 222 smokers with no previous diagnosis of COPD undertaken in a Spanish region in 2014-2016. The main variable was fixed airflow limitation by spirometry. The secondary variables (COPD factors) were: age, gender, smoking (pack-years and Fagerström test), body mass index, educational level, respiratory symptoms and exacerbations. A points system was developed to predict fixed airflow limitation based on secondary variables. The model was validated internally through bootstrapping, determining discrimination and calibration. The system was then integrated into a mobile application for Android. Fifty-seven patients (25.7%) presented fixed airflow limitation. The points system included as predictors: age, pack-years, Fagerström test and presence of respiratory symptoms. Internal validation of the system was very satisfactory, both in discrimination and calibration. In conclusion, a points system has been constructed to predict fixed airflow limitation in smokers with no previous COPD. This system can be integrated as a screening tool, though it should be externally validated in other geographical regions.

Only one prognostic model for laryngeal cancer has been published, but it has not been properly validated and is only applicable to patients treated with radiotherapy. Consequently, we constructed, internally validated and implemented in an App (Android), a predictive model of 5-year mortality in patients with glottic cancer in a cohort study of 189 patients with glottic cancer in 2004-2016 in Spain. The main variable was time-to-death. Secondary variables were age, gender, TNM, stage, smoking, alcohol consumption, histology and treatment. A scoring system to predict mortality at 5 years was constructed, validated internally by bootstrapping and then integrated into an Android app. In all, 70 patients died (37.0%, 76 deaths per 1,000 patient-years). The predictive model had the following prognostic factors: larger tumour size, greater degree of lymph node metastasis, higher stage, smoking and alcohol consumption. The internal validation of the model through bootstrapping was satisfactory. In conclusion, a points system to predict mortality at 5 years in patients with glottic cancer has been constructed, internally validated and integrated into an Android application. External validation is suggested to make available a quick and simple tool to establish the prognosis for these patients.

OBJECTIVES: The existing predictive models of laryngeal cancer recurrence present limitations for clinical practice. Therefore, we constructed, internally validated and implemented in a mobile application (Android) a new model based on a points system taking into account the internationally recommended statistical methodology. MATERIALS AND METHODS: This longitudinal prospective study included 189 patients with glottic cancer in 2004-2016 in a Spanish region. The main variable was time-to-recurrence, and its potential predictors were: age, gender, TNM classification, stage, smoking, alcohol consumption, and histology. A points system was developed to predict five-year risk of recurrence based on a Cox model. This was validated internally by bootstrapping, determining discrimination (C-statistics) and calibration (smooth curves). RESULTS: A total of 77 patients presented recurrence (40.7%) in a mean follow-up period of 3.4⯱â¯3.0â¯years. The factors in the model were: age, lymph node stage, alcohol consumption and stage. Discrimination and calibration were satisfactory. CONCLUSION: A points system was developed to obtain the probability of recurrence of laryngeal glottic cancer in five years, using five clinical variables. Our system should be validated externally in other geographical areas.

An association has been found between the C allele of the rs1414334 polymorphism in the HTR2C gene and the metabolic syndrome in psychiatric patients. However, no study has yet evaluated whether this allele is associated with smoking. To assess this issue, therefore, we performed a cross-sectional study with a sample of 166 adult patients treated with atypical antipsychotics in 2012-2013 in a region of Spain. The primary variable was the presence of the C allele of the rs1414334 polymorphism in the HTR2C gene. Secondary variables were the number of pack-years (number of cigarettes per day x number of smoking years ÷ 20), age, gender, schizophrenia, years since diagnosis, metabolic syndrome criteria and SCORE. A stepwise binary logistic regression model was constructed to determine associations between primary and secondary variables and their area under the ROC curve (AUC) was calculated. Of the total sample, 33 patients (19.9%) had the C allele of the polymorphism analyzed. Mean cigarette consumption was 11.6 pack-years. The multivariate analysis showed the following factors as associated with the polymorphism: higher cigarette consumption, being a woman, and not having abdominal obesity. The AUC was 0.706. An association was found between increased cigarette consumption over the years and the presence of the C allele of the rs1414334 polymorphism in the HTR2C gene.
En pacientes psiquiátricos, otros autores han encontrado una asociación entre el alelo C del polimorfismo rs1414334 del gen HTR2C y el síndrome metabólico. Ninguno de ellos ha valorado si este alelo se asocia con el consumo de tabaco, por lo que se decidió realizar un estudio en una región española valorando esta cuestión. Estudio observacional transversal de una muestra de 166 pacientes adultos tratados con antipsicóticos atípicos en 2012-2013. Variable principal: presencia del alelo C del polimorfismo rs1414334 del gen HTR2C. Variables secundarias: número de años-paquete (número de cigarrillos al día x número de años fumando ÷ 20), edad, sexo, esquizofrenia, años diagnosticados del trastorno, criterios de síndrome metabólico y SCORE. Se construyó un modelo de regresión logística binaria por pasos para determinar asociaciones entre la variable principal y las variables secundarias del estudio y se calculó su área bajo la curva ROC (ABC). Del total de la muestra, 33 pacientes presentaron el alelo C del polimorfismo analizado (19,9%). El consumo de tabaco medio fue de 11.6 paquetes-año. El modelo multivariante arrojó los siguientes factores asociados al polimorfismo: mayor consumo tabáquico, ser mujer y no tener obesidad abdominal. El ABC fue de 0,706. Se ha encontrado asociación entre un mayor consumo de tabaco a lo largo de los años y la presencia del alelo C del polimorfismo rs1414334 del gen HTR2C. Se necesitan trabajos que corroboren nuestros resultados.

AIMS: To analyse the association between psychological, labour and demographic factors and burnout in palliative care nursing. BACKGROUND: There is a lack of published research evaluating burnout in palliative care nursing. METHODS: This observational cross-sectional study involved 185 palliative care nurses in Mexico. The primary variables were burnout defined by its three dimensions (emotional exhaustion, depersonalization and personal accomplishment). As secondary variables, psychological, labour and demographic factors were considered. A binary logistic regression model was constructed to determine factors associated with burnout. RESULTS: A total of 69 nurses experienced high emotional exhaustion (37.3%), 65 had high depersonalization (35.1%) and 70 had low personal performance (37.8%). A higher proportion of burnout was found in the participants who were single parents, working >8 hr per day, with a medium/high workload, a lack of a high professional quality of life and a self-care deficit. CONCLUSION: Our multivariate models were very accurate in explaining burnout in palliative care nurses. These models must be externally validated to predict burnout and prevent future complications of the syndrome accurately. IMPLICATIONS FOR NURSING MANAGEMENT: Nurses who present the factors found should be the focus of interventions to reduce work stress.

Although predictive models exist for mortality in breast cancer (BC) (generally all cause-mortality), they are not applicable to all patients and their statistical methodology is not the most powerful to develop a predictive model. Consequently, we developed a predictive model specific for BC mortality at 5 and 10 years resolving the above issues. This cohort study included 287 patients diagnosed with BC in a Spanish region in 2003-2016. MAIN OUTCOME VARIABLE: time-to-BC death. Secondary variables: age, personal history of breast surgery, personal history of any cancer/BC, premenopause, postmenopause, grade, estrogen receptor, progesterone receptor, c-erbB2, TNM stage, multicentricity/multifocality, diagnosis and treatment. A points system was constructed to predict BC mortality at 5 and 10 years. The model was internally validated by bootstrapping. The points system was integrated into a mobile application for Android. Mean follow-up was 8.6 ± 3.5 years and 55 patients died of BC. The points system included age, personal history of BC, grade, TNM stage and multicentricity. Validation was satisfactory, in both discrimination and calibration. In conclusion, we constructed and internally validated a scoring system for predicting BC mortality at 5 and 10 years. External validation studies are needed for its use in other geographical areas.

BACKGROUND: Others have described a relationship between hemoglobin A levels and gestational age, gender and ethnicity. However, studies are needed to determine normal cut-off points considering these factors. To address this issue we designed a study to determine the percentiles of normality of neonatal hemoglobin A levels taking these factors into account. METHODS: This cross-sectional study involved 16,025 samples for sickle cell disease screening in the province of Alicante, Spain, which has a high immigration rate. The primary variable was hemoglobin A, and the secondary variables were gender, gestational age (preterm and full term) and maternal origin (Spain, the rest of Europe, North Africa, Sub-Saharan Africa, Latin America and Asia). Percentiles of normality (1 and 99) were obtained by origin, gender and gestational age using quantile regression models and bootstrap samples. The association between these percentiles of normality and altered levels (≥1%) of hemoglobin E was analyzed. We obtained the percentiles of normality (1 and 99) for each maternal origin, gender and gestational age. RESULTS: Of a total of 88 possible E carriers, 65 had above-normal hemoglobin A levels (74%). The levels of normality for hemoglobin A varied greatly according to the maternal origin and gestational age. CONCLUSION: With the levels of normality that we established it is possible to discard samples with unrecorded blood transfusions. Our methodology could be applied to other diseases in the neonatal screening.

To validate optical coherence tomography (OCT) for the diagnosis of referable retinopathy (severe, very severe or proliferative retinopathy, and macular edema) in diabetic patients. We performed a cross-sectional observational study. A random sample was analyzed comprising 136 eyes of diabetic patients referred to the hospital in Elche (Spain) with suspected referable retinopathy between October 2012 and June 2013. Primary variable: Referable retinopathy measured by ophthalmological examination of the retina. OCT data included: central foveal thickness, presence of intraretinal fluid, and fundus photographs. The receiver operating characteristic (ROC) curve was calculated to determine the minimum thickness value with a positive likelihood ratio >10. To determine the validity of OCT, the following diagnostic test was defined: Positive: if the patient had at least 1 of these criteria: foveal thickness greater than the point obtained on the previously defined ROC curve, intraretinal fluid, abnormal fundus photographs; Negative: none of the above criteria. Sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios, and Kappa statistic were determined. Of the 136 eyes, 48 had referable retinopathy (35.3%, 95% confidence interval [CI]: 27.3-43.3). The minimum thickness value with a positive likelihood ratio >10 was 275âµm. The diagnostic test constructed showed: sensitivity, 91.67% (95% CI: 79.13-97.30); specificity, 93.18% (95% CI: 85.19-97.20); positive predictive value, 88.00% (95% CI: 75.00-95.03); negative predictive value, 95.35% (95% CI: 87.87-98.50); positive likelihood ratio, 13.44 (95% CI: 6.18-29.24); negative likelihood ratio, 0.09 (95% CI: 0.03-0.23). The Kappa value was 0.84 (95% CI: 0.75-0.94, Pâ<â0.001. This study constructed a diagnostic test for referable diabetic retinopathy with type A evidence. Nevertheless, studies are needed to determine the validity of this test in the general diabetic population.

Others have analysed the relationship between inadequate behaviour by healthcare professionals in the diagnosis of dyslipidaemia (diagnostic inertia) and the history of cardiovascular risk factors. However, since no study has assessed cardiovascular risk scores as associated factors, we carried out a study to quantify diagnostic inertia in dyslipidaemia and to determine if cardiovascular risk scores are associated with this inertia. In the Valencian Community (Spain), a preventive programme (cardiovascular, gynaecologic and vaccination) was started in 2003 inviting persons aged ≥40 years to undergo a health check-up at their health centre. This cross-sectional study examined persons with no known dyslipidaemia seen during the first six months of the programme (n = 16, 905) but whose total cholesterol (TC) was ≥5.17 mmol/L. Diagnostic inertia was defined as lack of follow-up to confirm/discard the dyslipidaemia diagnosis. Other variables included in the analysis were gender, history of cardiovascular risk factors/cardiovascular disease, counselling (diet/exercise), body mass index (BMI), age, blood pressure, fasting blood glucose and lipids. TC was grouped as ≥/<6.20 mmol/L. In patients without cardiovascular disease and <75/≤65 years (n = 15, 778/13, 597), the REGICOR (REgistre GIroní del COr)/SCORE (Systematic COronary Risk Evaluation) cardiovascular risk functions were used to classify risk (high/low). Inertia was quantified and the adjusted odds ratios calculated from multivariate models. In the overall sample, the rate of diagnostic inertia was 52% (95% CI [51.2-52.7]); associated factors were TC ≥ 6.20 mmol/L, high or "not measured" BMI, hypertension, smoking and higher values of fasting blood glucose, systolic blood pressure and TC. In the REGICOR sample, the rate of diagnostic inertia was 51.9% (95% CI [51.1-52.7]); associated factors were REGICOR high and high or "not measured" BMI. In the SCORE sample the rate of diagnostic inertia was 51.7% (95% CI [50.9-52.5]); associated factors were SCORE high and high or "not measured" BMI. Diagnostic inertia existed in over half the patients and was associated with a greater cardiovascular risk.
RESUMO
As cardiovascular risk tables currently in use were constructed using data from the general population, the cardiovascular risk of patients admitted via the hospital emergency department may be underestimated. Accordingly, we constructed a predictive model for the appearance of cardiovascular diseases in patients with type 2 diabetes admitted via the emergency department. We undertook a four-year follow-up of a cohort of 112 adult patients with type 2 diabetes admitted via the emergency department for any cause except patients admitted with acute myocardial infarction, stroke, cancer, or a palliative status. The sample was selected randomly between 2010 and 2012. The primary outcome was time to cardiovascular disease. Other variables (at baseline) were gender, age, heart failure, renal failure, depression, asthma/chronic obstructive pulmonary disease, hypertension, dyslipidaemia, insulin, smoking, admission for cardiovascular causes, pills per day, walking habit, fasting blood glucose and creatinine. A cardiovascular risk table was constructed based on the score to estimate the likelihood of cardiovascular disease. Risk groups were established and the c-statistic was calculated. Over a mean follow-up of 2.31 years, 39 patients had cardiovascular disease (34.8%, 95% CI [26.0-43.6%]). Predictive factors were gender, age, hypertension, renal failure, insulin, admission due to cardiovascular reasons and walking habit. The c-statistic was 0.734 (standard error: 0.049). After validation, this study will provide a tool for the primary health care services to enable the short-term prediction of cardiovascular disease after hospital discharge in patients with type 2 diabetes admitted via the emergency department.
