Temporal trends and outcomes of heart transplantation in Spain (2002-2021): propensity score matching analysis to compare patients with and without type 2 diabetes.

BACKGROUND: The impact of Type 2 Diabetes (T2D) on the outcomes of heart transplantation (HT) has not yet been clearly established. The objectives of this study were to examine the trends in the prevalence of T2D among individuals who underwent a HT in Spain from 2002 to 2021, and to compare the clinical characteristics and hospitalization outcomes between HT recipients with and without T2D. METHODS: We used the national hospital discharge database to select HT recipients aged 35 and older. The International Classification of Diseases, Ninth and Tenth Revisions (ICD-9 and ICD-10) were used to identify patients with and without T2D. We also recorded comorbidities, complications of HT, and procedures. Propensity score matching (PSM) and Cox regression were used to analyze the effect of T2D on in-hospital mortality (IHM). RESULTS: Between 2002 and 2021, a total of 4429 HTs (T2D, 19.14%) were performed in Spain. The number of HTs in patients with T2D decreased from 2002 to 2005 (n = 171) to 2014-2017 (n = 154), then rose during 2018-2021 (n = 186). Complications of HT increased in patients with and without T2D over the study period (26.9% and 31.31% in 2002-2005 vs. 42.47% and 45.01% in 2018-2021, respectively). The results of the PSM showed that pneumonia and Gram-negative bacterial infections were less frequent in patients with T2D and that these patients less frequently required hemodialysis, extracorporeal membrane oxygenation (ECMO), and tracheostomy. They also had a shorter hospital stay and lower IHM than patients without diabetes. The variables associated with IHM in patients with T2D were hemodialysis and ECMO. IHM decreased over time in people with and without T2D. The Cox regression analysis showed that T2D was associated with lower IHM (HR 0.77; 95% CI 0.63-0.98). CONCLUSIONS: The number of HTs increased in the period 2018-2021 compared with 2002-2005 in patients with and without T2D. Over time, complications of HT increased in both groups studied, whereas IHM decreased. The presence of T2D is associated with lower IHM.

Trends in hospital admissions among children with asthma in Spain (2011-2020).

The purpose of this study is to describe and assess changes in incidence, clinical conditions, use of mechanical ventilation, length of hospital stay (LOHS), and in-hospital mortality (IHM) among children hospitalized with asthma in Spain from 2011 to 2020. We analyzed children aged 0 to 15 years hospitalized with an ICD code for asthma included in the Spanish National Hospital Discharge Database (SNHDD). The analysis was conducted for asthma as the primary diagnosis and with asthma in any diagnosis position. Joinpoint regression was used to assess time trends in incidence. We included a total of 85,664 children hospitalized with asthma; of these, 46,727 (54.55%) had asthma coded as the primary diagnosis. The number of boys was higher than the number of girls, irrespective of age group or diagnostic position. The frequency of asthma as primary diagnosis decreased from 55.7% in 2011 to 43.96% in 2020 (p < 0.001). The incidence of hospitalizations because of asthma decreased significantly from 2011 to 2020, with a faster decrease from 2018 onwards. Over time, the proportion of older children increased. In the year 2020, only 55 children had codes for asthma and COVID-19 in their discharge report, and this infection had no effect on hospitalizations this year. A significant increase in the use of non-invasive ventilation (NIV) was observed over time. Irrespective of the diagnostic position, LOHS and IHM remained stable over time, with the IHM under 0.1%.  Conclusion: Our results show a decrease in the incidence of hospital admissions with asthma either as the primary diagnosis or in any position. The age of children hospitalized seems to be increasing as the use of NIV. Better management of the disease from primary care and the emergency department as is the use of NIV could explain the reduction in incidence. What is Known: • Asthma is the most common chronic respiratory in childhood in high income countries. • The incidence of hospital admissions with asthma and associated factors is one of the best sources of information on morbidity trends and prognosis. What is New: • The incidence of hospital admissions for asthma in Spain decreased in children between 2011 and 2020 with a more frequent use of non-invasive mechanical ventilation and low mortality rates. • COVID-19 did not cause an increase in admissions with asthma in the year 2020.

Time trends (2001-2019) and sex differences in incidence and in-hospital mortality after lower extremity amputations among patients with type 1 diabetes in Spain.

BACKGROUND: We examined trends in incidence (2001-2019), clinical characteristics, and in-hospital outcomes following major and minor lower extremity amputations (LEAs) among type 1 diabetes mellitus (T1DM) patients in Spain and attempted to identify sex differences. METHODS: Retrospective cohort study using data from the Spanish National Hospital Discharge Database. We estimated the incidence of the LEA procedure stratified by type of LEA. Joinpoint regression was used to estimate incidence trends, and logistic regression was used to estimate factors associated with in-hospital mortality (IHM). RESULTS: LEA was coded in 6011 patients with T1DM (66.4% minor and 33.6% major). The incidence of minor LEA decreased by 9.55% per year from 2001 to 2009 and then increased by 1.50% per year, although not significantly, through 2019. The incidence of major LEA decreased by 13.39% per year from 2001 to 2010 and then remained stable through 2019. However, incidence increased in men (26.53% per year), although not significantly, from 2017 to 2019. The adjusted incidence of minor and major LEA was higher in men than in women (IRR 3.01 [95% CI 2.64-3.36] and IRR 1.85 [95% CI 1.31-2.38], respectively). Over the entire period, for those who underwent a minor LEA, the IHM was 1.58% (2.28% for females and 1.36% for males; p = 0.045) and for a major LEA the IHM was 8.57% (10.52% for females and 7.59% for males; p = 0.025). IHM after minor and major LEA increased with age and the presence of comorbid conditions such as peripheral arterial disease, ischemic heart disease or chronic kidney disease. Female sex was associated with a higher IHM after major LEA (OR 1.37 [95% CI 1.01-1.84]). CONCLUSIONS: Our data show a decrease in incidence rates for minor and major LEA in men and women with T1DM and a slight, albeit insignificant, increase in major LEA in men with T1DM in the last two years of the study. The incidence of minor and major LEA was higher in men than in women. Female sex is a predictor of IHM in patients with T1DM following major LEA.

Sex-related disparities in the incidence and outcomes of infective endocarditis according to type 2 diabetes mellitus status in Spain, 2016-2020.

BACKGROUND: We performed a study to assess sex-differences in incidence (2016-2020), clinical characteristics, use of therapeutic procedures, and in-hospital outcomes in patients with infective endocarditis (IE) according to T2DM status. METHODS: Ours was a retrospective cohort study using data from the Spanish National Hospital Discharge Database. We estimated the incidence of hospitalizations for IE in men and women aged ≥ 40 years with and without T2DM. Propensity score matching (PSM) and multivariable logistic regression were used to compare subgroups according to sex and the presence of T2DM. RESULTS: From 2016 to 2020, IE was coded in 9,958 patients (66.79% men). T2DM was diagnosed in 2,668 (26.79%). The incidence of IE increased significantly from 15.29 cases per 100,000 persons with T2DM in 2016 to 17.69 in 2020 (p < 0.001). However, this increment was significant only among men with T2DM (19.47 cases per 100,000 in 2016 vs. 22.84 in 2020; p = 0.003). The age-adjusted incidence of IE was significantly higher in people with T2DM (both sexes) than in those without T2DM (IRR, 2.86; 95% CI, 2.74-2.99). The incidence of IE was higher in men with T2DM than in women with T2DM (adjusted IRR, 1.85; 95% CI, 1.54-3.31). After PSM, in-hospital mortality (IHM) was higher among T2DM women than matched T2DM men (22.65% vs. 18.0%; p = 0.018). The presence of T2DM was not associated with IHM in men or women. CONCLUSIONS: T2DM is associated with a higher incidence of hospitalization for IE. Findings for T2DM patients who had experienced IE differed by sex, with higher incidence rates and lower IHM in men than in women. T2DM was not associated to IHM in IE in men or in women.

Sex-differences in incidence of hospitalizations and in hospital mortality of community-acquired pneumonia among children in Spain: a population-based study.

The aim of this study is to examine trends from 2016 to 2019 in the incidence of hospitalizations and in-hospital mortality (IHM) of subjects < 18 years with community-acquired pneumonia (CAP), assessing possible sex differences. We used Spanish national hospital discharge data to select all patients < 18 years with CAP. We identified 43,511 children (53% boys) hospitalized with CAP. The incidence of CAP was significantly higher in boys than in girls, with an age-adjusted incidence rate ratio of 1.05 (95%CI 1.03-1.07) for boys compared to girls, and rose from 126 per 100,000 children in 2016 to 131 in 2019 (p < 0.0001). There were no sex differences in isolated pathogens, comorbidities, length of hospital stay, or IHM. Variables independently associated with IHM were age 10 to 17 years, congenital heart disease, neurological diseases, and use of invasive mechanical ventilation. Asthma was a protective factor for IHM among girls. CONCLUSION: The incidence of hospital admissions for CAP was higher among boys than among girls and rose significantly from 2016 to 2019. There were no sex differences in hospital outcomes. Age 10 to 17 years, congenital heart disease, neurological diseases, and use of mechanical ventilation were risk factors for IHM in both sexes, while asthma was a protective factor among girls. No differences were found in IHM over time. WHAT IS KNOWN: • Community-acquired pneumonia is one of the most common reasons for hospitalizations among children. • There are few studies that allow to know the evolution of community-acquired pneumonia in children. WHAT IS NEW: • Incidence of hospital admissions for community-acquired pneumonia was higher in boys than girls and it rose significantly from 2016 to 2019. • Age 10 to 17 years, congenital heart disease, neurological diseases and use of mechanical ventilation were risk factors for in-hospital mortality in both sexes.

Analysis of Prior Aspirin Treatment on in-Hospital Outcome of Geriatric COVID-19 Infected Patients.

Background and Objectives: Aspirin (ASA) is a commonly used antithrombotic drug that has been demonstrated to reduce venous thromboembolism. The aim was to analyze if geriatric COVID-19 patients undergoing a 100 mg/day Aspirin (ASA) treatment prior to hospitalization differ in hospital outcome compared to patients without previous ASA therapy. Materials and Methods: An observational retrospective study was carried out using an anonymized database including geriatric COVID-19 patients (March to April 2020) admitted to Madrid Hospitals Group. A group of COVID-19 patients were treated with low ASA (100 mg/day) prior to COVID-19 infection. Results: Geriatric ASA-treated patients were older (mean age over 70 years; n = 41), had higher frequency of hypertension and hyperlipidemia, and upon admission had higher D-dimer levels than non-ASA-treated patients (mean age over 73 years; n = 160). However, patients under ASA treatment did not show more frequent pulmonary thromboembolism (PE) than non-ASA-treated patients. ASA-treated geriatric COVID-19-infected patients in-hospital < 30 days all-cause mortality was more frequent than in non-ASA-treated COVID-19 patients. In ASA-treated COVID-19-infected geriatric patients, anticoagulant therapy with low molecular weight heparin (LMWH) significantly reduced need of ICU care, but tended to increase in-hospital < 30 days all-cause mortality. Conclusions: Prior treatment with a low dose of ASA in COVID-19-infected geriatric patients increased frequency of in-hospital < 30 days all-cause mortality, although it seemed to not increase PE frequency despite D-dimer levels upon admission being higher than in non-ASA users. In ASA-treated geriatric COVID-19-infected patients, addition of LMWH therapy reduced frequency of ICU care, but tended to increase in-hospital < 30 days all-cause mortality.

Sex-related disparities in the incidence and outcomes of hemorrhagic stroke among type 2 diabetes patients: a propensity score matching analysis using the Spanish National Hospital Discharge Database for the period 2016-18.

BACKGROUND: To analyze incidence, use of therapeutic procedures, use of oral anticoagulants (OACs) and antiplatelet agents prior to hospitalization, and in-hospital outcomes among patients who were hospitalized with hemorrhagic stroke (HS) according to the presence of type 2 diabetes mellitus (T2DM) in Spain (2016-2018) and to assess the role of sex differences among those with T2DM. METHODS: Using the Spanish National Hospital Discharge Database we estimated the incidence of HS hospitalizations in men and women aged ≥ 35 years with and without T2DM. Propensity score matching (PSM) was used to compare population subgroups according to sex and the presence of T2DM. RESULTS: HS was coded in 31,425 men and 24,975 women, of whom 11,915 (21.12%) had T2DM. The adjusted incidence of HS was significantly higher in patients with T2DM (both sexes) than in non-T2DM individuals (IRR 1.15; 95% CI 1.12-1.17). The incidence of HS was higher in men with T2DM than in T2DM women (adjusted IRR 1.60; 95% CI 1.57-1.63). After PSM, men and women with T2DM have significantly less frequently received decompressive craniectomy than those without T2DM. In-hospital mortality (IHM) was higher among T2DM women than matched non-T2DM women (32.89% vs 30.83%; p = 0.037), with no differences among men. Decompressive craniectomy was significantly more common in men than in matched women with T2DM (5.81% vs. 3.33%; p < 0.001). IHM was higher among T2DM women than T2DM men (32.89% vs. 28.28%; p < 0.001). After adjusting for confounders with multivariable logistic regression, women with T2DM had a 18% higher mortality risk than T2DM men (OR 1.18; 95% CI 1.07-1.29). Use of OACs and antiplatelet agents prior to hospitalization were associated to higher IHM in men and women with and without T2DM. CONCLUSIONS: T2DM is associated with a higher incidence of HS and with less frequent use of decompressive craniectomy in both sexes, but with higher IHM only among women. Sex differences were detected in T2DM patients who had experienced HS, with higher incidence rates, more frequent decompressive craniectomy, and lower IHM in men than in women.

Are there sex differences in the effect of type 2 diabetes in the incidence and outcomes of myocardial infarction? A matched-pair analysis using hospital discharge data.

BACKGROUND: To analyze incidence, use of therapeutic procedures, and in-hospital outcomes in patients with ST elevation myocardial infarction (STEMI) and non-ST elevation myocardial infarction (NSTEMI) according to the presence of type 2 diabetes (T2DM) in Spain (2016-2018) and to investigate sex differences. METHODS: Using the Spanish National Hospital Discharge Database, we estimated the incidence of myocardial infarctions (MI) in men and women with and without T2DM aged ≥ 40 years. We analyzed comorbidity, procedures, and outcomes. We matched each man and woman with T2DM with a non-T2DM man and woman of identical age, MI code, and year of hospitalization. Propensity score matching was used to compare men and women with T2DM. RESULTS: MI was coded in 109,759 men and 44,589 women (30.47% with T2DM). The adjusted incidence of STEMI (IRR 2.32; 95% CI 2.28-2.36) and NSTEMI (IRR 2.91; 95% CI 2.88-2.94) was higher in T2DM than non-T2DM patients, with higher IRRs for NSTEMI in both sexes. The incidence of STEMI and NSTEMI was higher in men with T2DM than in women with T2DM. After matching, percutaneous coronary intervention (PCI) was less frequent among T2DM men than non-T2DM men who had STEMI and NSTEMI. Women with T2DM and STEMI less frequently had a code for PCI that matched that of non-T2DM women. In-hospital mortality (IHM) was higher among T2DM women with STEMI and NSTEMI than in matched non-T2DM women. In men, IHM was higher only for NSTEMI. Propensity score matching showed higher use of PCI and coronary artery bypass graft and lower IHM among men with T2DM than women with T2DM for both STEMI and NSTEMI. CONCLUSIONS: T2DM is associated with a higher incidence of STEMI and NSTEMI in both sexes. Men with T2DM had higher incidence rates of STEMI and NSTEMI than women with T2DM. Having T2DM increased the risk of IHM after STEMI and NSTEMI among women and among men only for NSTEMI. PCI appears to be less frequently used in T2DM patients After STEMI and NSTEMI, women with T2DM less frequently undergo revascularization procedures and have a higher mortality risk than T2DM men.

Trend from 2001 to 2015 in the prevalence of bronchiectasis among patients hospitalized for asthma and effect of bronchiectasis on the in-hospital mortality.

OBJECTIVE: We aimed to analyze the prevalence of bronchiectasis among patients hospitalized with asthma and to assess the effect of suffering bronchiectasis on in-hospital mortality (IHM). METHODS: We used the Spanish National Hospital Discharge Database from 2000 to 2015 to evaluate all admissions for asthma exacerbation as the main diagnosis, dividing them according to the presence or absence of associated bronchiectasis. We assessed time trends in the prevalence, clinical characteristics, length of hospital stay, costs, and IHM. RESULTS: Of 342,644 admissions for asthma, 10,377 (3.02%) had bronchiectasis. The prevalence of bronchiectasis increased from 2.16% in 2001 to 4.47% in 2015 (p < 0.001). Compared to patients without bronchiectasis, those with bronchiectasis were more frequently women (77.06% vs. 22.94%, p < 0.001), were older (68.87 ± 15.16 vs. 47.05 ± 30.66 years, p < 0.001) and had more comorbid conditions (Charlson comorbidity index ≥ 2: 9.45% vs. 6.58%, p < 0.001). Pseudomonas (8% vs. 0.66%, p < 0.001), Aspergillus (0.93% vs. 0.15%, p < 0.001), eosinophilia (0.29% vs. 0.17%, p = 0.005) and IHM (2.07% vs. 1.2%, p < 0.001) were more frequent in patients with bronchiectasis. After multivariable adjustments, IHM was not associated with bronchiectasis. The presence of bronchiectasis was associated with a longer length of hospital stay and higher costs. CONCLUSIONS: Admissions for asthma with bronchiectasis have increased over time in Spain. In our investigation, the presence of bronchiectasis was not associated with higher IHM, but it increased the length of hospital stay and costs.

Female Gender Is Associated with a Higher Prevalence of Chronic Neck Pain, Chronic Low Back Pain, and Migraine: Results of the Spanish National Health Survey, 2017.

OBJECTIVES: To assess the prevalence of chronic neck pain (CNP), chronic low back pain (CLBP), and migraine headache (MH) in the Spanish population and to identify sociodemographic and health-related variables associated with CNP, CLBP, and MH. DESIGN: Observational study. SETTING: Spain. SUBJECTS: A total of 22,511 persons 18 years of age or older (10,304 males and 12,207 females) who participated in the 2017 Spanish National Health Survey. METHODS: Stratified three-stage sampling was applied. CNP, CLBP, and MH were the dependent variables. The analysis was conducted separately by gender. Sociodemographic features, self-perceived health status, lifestyle habits, comorbidities, and pain features were analyzed by using logistic regression models. RESULTS: Females reported a higher prevalence of CNP, CLBP, and MH (P < 0.001) than males. For both sexes, anxiety and/or depression and poor self-rated health were associated with a significantly increased prevalence of CNP, CLBP, and MH. For CNP and CLBP, the identified associated factors were older age and limitations to usual activity. For CNP and MH, the most common associated factor was comorbid respiratory disease. CONCLUSIONS: Our study identified several factors associated with CNP, CLBP, and MH in Spanish female and male adults, with potential implications for health care providers.

The influence of sex on ischemic stroke incidence, therapeutic procedures and in-hospital mortality: Results of the Spanish National Hospital Discharge.

BACKGROUND: Previous research has revealed sex-related differences in outcomes for people admitted to hospitals for ischemic stroke. We aimed to analyse the incidence, use of invasive procedures and in-hospital outcomes of ischemic stroke in Spain (2016-2018) using the Spanish National Hospital Discharge Database. We sought sex-related differences in incidence and in-hospital outcomes over time. METHODS: We estimated the incidence of ischemic stroke in men and women. We analysed comorbidities (Charlson's comorbidity index, cardiovascular risk factors, alcohol abuse and atrial fibrillation), procedures (mechanical ventilation, endovascular thrombectomy and thrombolytic therapy) and outcomes. We matched each woman with a man with identical age, type of ischemic stroke and year of hospitalisation. We built Poisson regression models to obtain adjusted incidence rate ratios (IRRs). We tested in-hospital mortality (IHM) with logistic regression analyses. RESULTS: Ischemic stroke was coded in 172 255 patients aged ≥35 years (92 524 men 53.7%). Men showed higher incidence rates (216.9 vs. 172.3/105 ; P < .001; IRR = 1.57 (95% CI:1.55-1.59) than women. After matching, the use of endovascular thrombectomy (5.1% vs. 4.0%; P < .001) and thrombolytic therapy (7.6% vs. 6.8%; P < .001) was higher among women. IHM was significantly higher in women than in matched men (11.2% vs. 10.4%; P < .001). Women had a lower IHM than matched men when endovascular thrombectomy (9.4% vs. 12.1%; P = .001) or thrombolytic therapy (6.7% vs. 8.3%; P = .003) was coded. Patients of both sexes admitted for ischemic stroke who received thrombolytic therapy had lower IHM (OR = 0.76; 95% CI:0.68-0.85 among men; and OR = 0.58; 95% CI:0.52-0.64 among women), but endovascular thrombectomy was associated with a lower IHM only among women (OR = 0.58; 95% CI:0.51-0.66). After multivariable adjusting, women admitted to the hospital for ischemic stroke had a significantly higher IHM than men (OR = 1.16; 95% CI:1.12-1.21). CONCLUSION: Men had higher incidence rates of ischemic stroke than women. Women more often underwent thrombolytic therapy and endovascular thrombectomy but had a higher IHM.

The significance of heart failure in hospitalised patients with pulmonary embolism. A gender-specific analysis.

BACKGROUND: Heart failure (HF) is a risk factor for the development of pulmonary embolism (PE). Few studies have examined sex differences in risk of PE among HF patients. AIMS: (a) To examine the incidence, characteristics and in-hospital outcomes among patients hospitalised with PE according to HF status; (b) to compare the in-hospital mortality (IHM) after PE between HF and non-HF patients and (c) to identify variables associated with IHM. All analyses were stratified by sex. METHODS: We included all adult patients hospitalised for PE from 1 January 2016 to 31 December 2018. Data were collected from the Spanish National Hospital Discharge Database. Poisson regression models were constructed to quantify the difference in the incidences between HF and non-HF populations. Propensity score matching (PSM) was used to obtain comparable subgroups by sex and HF status. RESULTS: We identified 46,835 PE hospitalisations, 11.4% with HF. Adjusted incidence of PE was higher in HF patients than in those without HF (Incidence Rate Ratio 1.11; 95% CI 1.08-1.13). Crude and PSM adjusted IHM were significantly higher in men and women hospitalised with PE suffering HF than in men and women without HF (P < .001). Women with HF who suffered a PE had lower IHM than men with this condition (P < .001) after adjusting. CONCLUSIONS: Adjusted incidence of PE was higher in HF patients than in those without HF. After PSM suffering, HF was associated to higher IHM in men and women. Women with PE and HF had lower IHM than men with these conditions.

Gender differences in incidence and in-hospital outcomes of community-acquired, ventilator-associated and nonventilator hospital-acquired pneumonia in Spain.

AIMS: We aim to compare the incidence and in-hospital outcomes of community-acquired pneumonia (CAP), ventilator-associated pneumonia (VAP) and nonventilator hospital-acquired pneumonia (NV-HAP) according to gender. METHODS: This was a retrospective observational epidemiological study using the Spanish National Hospital Discharge Database for the years 2016 and 2017. RESULTS: Of 277 785 hospital admissions, CAP was identified in 257 455 (41.04% females), VAP was identified in 3261 (30.42% females) and NV-HAP was identified in 17 069 (36.58% females). The incidence of all types of pneumonia was higher amongst males (CAP: incidence rate ratio [IRR] 1.05, 95% CI 1.03-1.06; VAP: IRR 1.36, 95% CI 1.26-1.46; and NV-HAP: IRR 1.16, 95% CI 1.14-1.18). The crude in-hospital mortality (IHM) rate for CAP was 11.44% in females and 11.80% in males (P = .005); for VAP IHM, the rate was approximately 35% in patients of both genders and for NV-HAP IHM, the rate was 23.97% for females and 26.40% for males (P < .001). After multivariable adjustment, in patients of both genders, older age and comorbidities were factors associated with IHM in the three types of pneumonia analysed. Female gender was a risk factor for IHM after VAP (OR 1.24; 95% CI 1.06-1.44), and no gender differences were found for CAP or NV-HAP. CONCLUSIONS: Our findings show a difference between females and males, with females presenting a lower incidence of all types of pneumonia. However, female gender was a risk factor for IHM after VAP.

Impact of COPD on outcomes in hospitalized patients treated with transcatheter aortic valve implantation or surgical aortic valve replacement in Spain.

OBJECTIVES: To describe the use of transcatheter aortic valve implantation (TAVI) and conventional surgery (SAVR) among hospitalized patients with and without COPD, to compare the in-hospital mortality (IHM), length of hospital stay (LOHS) and cost between patients with COPD undergoing TAVI and SAVR and to identify factors associated to IHM among these patients. BACKGROUND: TAVI would be expected to be less invasive and safer than SAVR among COPD patients. METHODS: We analyzed patients whose medical procedures included TAVI and SAVR included in the Spanish National Hospital Discharge Database, 2014-2015. We stratified analysis by COPD status. Propensity score matching (1:2) was performed to assess the outcomes of TAVI vs. SAVR among COPD patients. RESULTS: We identified 2,141 and 16,013 patients who underwent TAVI (27.60% with COPD) and SAVR (19.31% with COPD) respectively. For TAVI, we found no differences in IHM according to COPD status. Patients undergoing SAVR and suffering COPD had higher IHM than patients without COPD (adj.OR 1.32; 95%CI 1.10-1.58). After propensity score matching, IHM (8.35% vs. 5.83%, p = .040) and LOHS (18.62 days vs. 13.62; p < .001) were higher in COPD patients who underwent SAVR than those who underwent TAVI. CONCLUSIONS: COPD patients undergoing TAVI did not have a worse prognosis compared to non-COPD patients during hospitalization. However, for SAVR, patients with COPD had significantly higher mortality than patients without this condition. COPD patients who underwent SAVR had higher IHM and LOHS than propensity score matched TAVI patients.

Infective endocarditis according to type 2 diabetes mellitus status: an observational study in Spain, 2001-2015.

BACKGROUND: The main aims of this study were to describe trends and outcomes during admission for infective endocarditis (IE) in people ≥ 40 years old with or without type 2 diabetes distributed in five time-periods (2001-2003; 2004-2006; 2007-2009; 2010-2012 and 2013-2015), using Spanish national hospital discharge data. METHODS: We estimated admission rates by diabetes status. We analyzed comorbidity, therapeutic procedures, and outcomes. We built Poisson regression models to compare the adjusted time-trends in admission rates. Type 2 diabetes cases were matched with controls using propensity score matching (PSM). We tested in-hospital mortality (IHM) in logistic regression analyses. RESULTS: We identified 16,626 hospitalizations in patients aged ≥ 40 years for IE in Spain, 2001-2015. The incidence of IE increased significantly from 6.0/100,000 per year to 13.1/100,000 per year (p < 0.001) in the population with type 2 diabetes, and from 3.9/100,000 per year to 5.5/100,000 per year (p < 0.001) in the population without diabetes, over the study period. The adjusted incidence of IE was 2.2-times higher among patients with diabetes than among those without diabetes (IRR = 2.2; 95% CI 2.1-2.3). People with type 2 diabetes less often underwent heart valve surgery than people without diabetes (13.9% vs. 17.3%; p < 0.001). Although IHM decreased significantly in both groups over time, it represented 20.8% of IE cases among diabetes patients and 19.9% among PSM matched controls (p = 0.337). Type 2 diabetes was not associated with a higher IHM in people admitted to the hospital for IE (OR = 1.1; 95% CI 0.9-1.2). CONCLUSION: Incidence rates of IE in Spain, among those with and without T2DM, have increased during the period 2001-2015 with significantly higher incidence rates in the T2DM population. In our population based study and after PSM we found that T2DM was not a predictor of IHM in IE.

Impact of type 2 diabetes mellitus in the utilization and in-hospital outcomes of surgical mitral valve replacement in Spain (2001-2015).

BACKGROUND: The main aims of this study were to examine the incidence and in-hospital outcomes of mechanical and bioprosthetic surgical mitral valve replacement (SMVR) among patients with and without T2DM. METHODS: We performed a retrospective study using the Spanish National Hospital Discharge Database from 2001 to 2015. We included patients with SMVR codified in their discharge report. We grouped admissions by diabetes status. Propensity score matching (PSM) was used to compare outcomes of isolated SMVR. RESULTS: We identified 42,937 patients (16.41% with T2DM). Incidence rates of mechanical and bioprosthetic SMVR were higher among T2DM patients than among non-T2DM patients. In both groups of patients, the use of bioprosthetic SMVR increased over time. The use of mechanical valves remained stable among T2DM patients. In T2DM and non-T2DM patients with mechanical SMVR, in hospital mortality (IHM) and MACCE decreased significantly (p < 0.001) from 2001 to 2015. T2DM patients had an overall 11.37% IHM, compared with 10.76% among non-T2DM patients (p = 0.176). Regarding MACCE figures were 14.72% vs. 14.22% (p = 0.320) after mechanical SMVR. Total crude IHM were 14.29% for T2DM patients and 15.13% for those without T2DM with bioprosthetic SMVR (p = 0.165) and 18.22 vs. 19.64%, for a MACCE (p = 0.185). Using PSM we found that the IHM and the MACCE of isolated SMVR did not differ significantly between patients with or without T2DM beside the type of valve replacement. Among T2DM patients, those who received bioprosthetic valves had higher IHM (14.29% vs. 11.37%; p = 0.003) and a higher rate of MACCE (18.22% vs. 14.72%; p = 0.001) than T2DM patients with mechanical SMVR. CONCLUSIONS: In Spain from 2001 to 2015, the incidence rates of hospitalization to undergo mechanical or bioprosthetic SMVR were higher among the population suffering T2DM than among the non-T2DM population. In both groups of patients the use of bioprosthetic SMVR increased over time and the use of mechanical valves remained stable in T2DM. T2DM patients have IHM and MACCE after mechanical and bioprosthetic SMVR which are not significantly different to those found among non-diabetic patients. Among T2DM patients, the crude IHM was significantly higher in those who received a bioprosthetic SMVR than those with mechanical SMVR.

Gender Differences in the Prevalence and Characteristics of Pain in Spain: Report from a Population-Based Study.

OBJECTIVE: To assess the prevalence and characteristics of chronic neck pain, chronic low back pain, and migraine or frequent headaches among Spanish adults in 2014 according to gender, to identify predictors for each of these types of pains, and to compare the prevalence with those found in 2009. DESIGN: Cross-sectional study. SETTING: Spain. METHODS: We used data collected from the 2014 European Health Interview Survey (N = 22,842). Sociodemographic features, self-rated health status, lifestyle habits, comorbid conditions, pain characteristics, and self-reported use of medications were analyzed. RESULTS: The prevalence of all types of pain was significantly higher among women than men. For chronic neck pain, the figures were 25.68% vs 12.54%, for chronic low back pain, 27.03% vs 18.83%, and for migraine or frequent headaches, 15.93% vs 6.74%, in women and men, respectively. Predictors of these types of pain included female gender, advanced age, poor self-rated health, psychological distress, comorbidities, and obesity. The prevalence of neck pain and low back pain increased from 2009 to 2014 for both sexes, and the prevalence of migraine or frequent headaches remained stable over time. CONCLUSIONS: The prevalence and intensity of all the forms of chronic pain were higher among women. Women experiencing pain used prescribed medications for pain, anxiety, and/or depression and sleeping pills more than men. The prevalence of chronic neck and low back has increased in the last five years in Spain, and the prevalence of migraine or frequent headaches has remained stable.

Gender differences in incidence and in-hospital outcomes of surgical aortic valve replacement in Spain, 2001-15.

BACKGROUND: we aim to examine trends in the incidence of surgical aortic valve replacement (SAVR) among women and men in Spain from 2001 to 2015; compare in-hospital outcomes for mechanical and bioprosthetic SAVR by gender and; to identify factors associated with in-hospital mortality (IHM) after SAVR. METHODS: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2001-15. We included patients that had SAVR as procedure in their discharge report. Propensity score matching (PSM) was performed to assess the impact of gender on the outcomes of mechanical and bioprosthetic SAVR. RESULTS: We identified 86 578 patients who underwent SAVR (40% women). Incidence of SVAR was higher in men (incidence rate ratio 1.57; 95%CI 1.55-1.59). In 2001, 73.36% of the men and 71.57% of women received a mechanical prosthesis; these proportions decreased to 43.04% in men and 35.89% in women in 2015, whereas bioprosthetic SAVR increased to 56.96% and 64.11%. After PSM we found that IHM was higher in women than in matched men for mechanical (8.94% vs. 6.79%; P < 0.001) and bioprosthetic (6.51 vs. 5.42%; P = 0.001) SAVR. The mean length of hospital stay was longer (19.54 vs. 18.74 days; P < 0.001) among females than males undergoing mechanical SAVR. Higher IHM after SAVR was associated with older age, comorbidities (except diabetes and atrial fibrillation), concomitant coronary artery bypass graft and emergency room admission. CONCLUSIONS: This nation-wide analysis over 15 years of gender-specific outcomes after SAVR showed that, after PSM women have significantly higher IHM after mechanical and bioprosthetic SAVR than men.

Impact of type 2 diabetes mellitus in the utilization and in-hospital outcomes of surgical aortic valve replacement in Spain (2001-2015).

BACKGROUND: The aims of this study were to examine trends in the incidence and in-hospital outcomes of SAVR among T2DM patients from 2001 to 2015, to compare clinical variables among T2DM patients and matched non-T2DM patients hospitalized for SAVR and to identify factors associated with in-hospital mortality (IHM) among T2DM patients. METHODS: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2001-2015. We included patients who had SAVR as the procedure in their discharge report. For each T2DM patient, we selected a sex-, age-, implanted valve type- and year-matched nondiabetic patient. RESULTS: We identified 78,223 patients who underwent SAVR (23.49% with T2DM). The prevalence of T2DM increased significantly (p < 0.001) from 16.7% in 2001-2003 to 23.5% in 2012-2015. The incidence of SAVR increased significantly from 28.99 cases in 2001 to 65.79 cases in 2015 per 100,000 individuals in the T2DM population. Using Poisson regression models, we found that the incidence of SAVR was 2.60 times higher among patients with T2DM than among those without diabetes (IRR 2.60; 95% CI 2.56-2.65). The incidence of mechanical SAVR among T2DM patients remained stable from 2001 to 2015, and bioprosthetic SAVR rose from 8.29 to 41.74 cases per 100,000 individuals in the T2DM patient population (p < 0.001). We matched 8835 and 9543 patients who underwent mechanical and bioprosthetic SAVR, respectively. IHM decreased over time in T2DM patients and non-T2DM patients (from 8.89% and 7.81% to 3.88% and 5.07%, respectively). IHM was significantly lower in T2DM patients than in nondiabetic subjects who underwent bioprosthetic SAVR (4.77% vs. 6.04%, p < 0.001), with similar results obtained for mechanical valves (7.11% and 7.77%). CONCLUSIONS: The incidence of SAVR was higher in T2DM patients, and the incidence of bioprosthetic SAVR increased significantly among T2DM subjects. IHM decreased over time, regardless of the existence or absence of T2DM and the valve type. IHM was significantly lower in T2DM patients than in nondiabetic patients who underwent bioprosthetic SAVR.

Incidence and in-hospital outcomes of Clostridium difficile infection among type 2 diabetes patients in Spain.

AIM: To examine incidence and in-hospital outcomes of Clostridium difficile infection (CDI) among patients with type 2 diabetes (T2DM); compare clinical variables among T2DM patients with matched non-T2DM patients hospitalised with CDI and identify factors associated with in-hospital mortality (IHM) among T2DM patients. METHODS: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2001-2015. We included patients that had CDI as primary or secondary diagnosis in their discharge report. For each T2DM patient, we selected a gender, age, readmission status and year-matched non-diabetic patient. RESULTS: We identified 44 695 patients with CDI (21.19% with T2DM). We matched 3040 and 5987 couples with a primary and secondary diagnosis of CDI, respectively. Incidence of CDI was higher in T2DM patients (IRR per hospital admission 1.12; 95% CI 1.09-1.14, IRR per population 1.26; 95% CI 1.22-1.29). IHM decreased over time in T2DM and non-T2DM patients (from 15.36% and 13.35%, in 2001-2003 to 10.36% and 11.73% in 2013-2015), despite a concomitant increase in CDI diagnoses overtime. Among those with CDI as secondary diagnosis IHM was higher in nondiabetic 16.17% than in T2DM patients 13.19% (P < 0.001). In T2DM patients higher mortality rates were associated with older age, comorbidities, severe CDI, and readmission. Primary diagnosis of CDI was associated with lower IHM (OR 0.71; 95% CI 0.60-0.84) than secondary diagnosis. CONCLUSIONS: Incidence of CDI was higher in T2DM patients. IHM decreased over time, regardless of the existence or not of T2DM. IHM was significantly lower in T2DM patients with CDI as primary diagnosis than non diabetic patients.
