Impact of anxiety and depression on the prognosis of copd exacerbations.

BACKGROUND: Frequent and highly prevalent as comorbidities in Chronic Obstructive Pulmonary Disease (COPD) patients, both depression and anxiety seem to have an impact on COPD prognosis. However, they are underdiagnosed and rarely treated properly. AIM: To establish the prevalence of depression and anxiety in patients admitted for Acute Exacerbation of COPD (AECOPD) and determine their influence on COPD prognosis. METHODS: Prospective observational study conducted from October 1, 2016 to October 1, 2018 at the following centers in Galicia, Spain: Salnés County Hospital, Arquitecto Marcide, and Clinic Hospital Complex of Santiago de Compostela. Patients admitted for AECOPD who agreed to participate and completed the anxiety and depression scale (HADS) were included in the study. RESULTS: 288 patients (46.8%) were included, mean age was 73.7 years (SD 10.9), 84.7% were male. 67.7% patients were diagnosed with probable depression, and depression was established in 41.7%; anxiety was probable in 68.2% and established in 35.4%. 60.4% of all patients showed symptoms of both anxiety and depression. Multivariate analysis relates established depression with a higher risk of late readmission (OR 2.06, 95% CI 1.28; 3.31) and a lower risk of mortality at 18 months (OR 0.57, 95% CI 0.37; 0.90). CONCLUSION: The prevalence of anxiety and depression in COPD patients is high. Depression seems to be an independent factor for AECOPD, so early detection and a multidisciplinary approach could improve the prognosis of both entities. The study was approved by the Ethical Committee of Galicia (code 2016/460).

Blood eosinophils could be useful as a biomarker in chronic obstructive pulmonary disease exacerbations.

Introduction The aim of analysing the usefulness of the blood eosinophil count (BEC) as a prognostic marker in exacerbations of patients with Chronic Obstructive Pulmonary Disease (COPD), evaluating its relationship with hospital mortality, the length of stay and the early and late re-admissions. Materials and Methods We have carried out a retrospective study including all patients who required hospital admission from 1 January 2008 to 31 December 2009, with a diagnosis on hospital discharge of COPD exacerbation. These patients were classified using three cut-off points of BEC: less than 200 vs ≥ 200/µL, less than 300 vs ≥ 300/µL and less than 400 vs ≥ 400/µL. Results There were a total of 1626 hospital admissions during the study period with the diagnosis of exacerbation of COPD. In this study we have included 358 patients. The probability of any late re-admission increased with a BEC ≥ 300/µL (odds ratio: 1.684) and for those with a BEC ≥ 400/µL (odds ratio: 2.068). The BEC does not appear to be related to hospital mortality or the probability of early re-admission after an exacerbation of COPD. Conclusions In our study an elevated BEC is associated with a higher incidence of late hospital readmissions in COPD exacerbations.

Prognostic Usefulness of Basic Analytical Data in Chronic Obstructive Pulmonary Disease Exacerbation.

Introduction: COPD causes high morbidity and mortality and high health costs. Thus, identifying and analyzing the distinctive and treatable traits seems useful to optimize the management of AEPOC patients. While various biomarkers have been researched, no solid data for systematic use have been made available. Aim: Assessing the short-term prognostic usefulness of clinical and analytical parameters available in routine clinical practice in COPD exacerbations. Material and methods: Multicenter prospective observational study conducted between 2016 and 2018. Patients admitted for COPD exacerbation who agreed to participate and signed an informed consent form were included. Prolonged stay, in-hospital mortality or early readmission was considered an unfavorable progression. 30-Day mortality was also analyzed. Results: 615 patients were included. Mean age was 73.9 years (SD 10.6); 86.2% were male. Progression of 357 patients (58%) was considered unfavorable. Mortality at 1 month from discharge was 6.7%. The multivariate analysis shows a relationship between the CRP/Albumin ratio and unfavorable progression (OR 1.008, 95% CI 1.00; 1.01), as well as increased risk of death at 1 month from discharge with elevated urea (OR 1.01, 95% CI 1.005; 1.02) and troponin T (OR 2.21, 95% CI 1.06; 4.62). Conclusion: Elevated CRP/Albumin, urea and TnT are prognostic indicators of poor short-term outcome in patients admitted for COPD exacerbation. Cardiovascular comorbidity and systemic inflammation could explain these findings.

Introducción: : La EPOC provoca una elevada morbimortalidad y elevados costes sanitarios. Identificar y analizar los rasgos distintivos y tratables parece útil para optimizar el tratamiento de los pacientes con AEPOC. Se han investigado varios biomarcadores sin que de momento se disponga de datos sólidos para su uso sistemático. Objetivo: Evaluar la utilidad pronóstica a corto plazo de los parámetros clínicos y analíticos disponibles en la práctica clínica habitual en las exacerbaciones de la EPOC. Material y métodos: Estudio observacional prospectivo multicéntrico realizado entre 2016 y 2018. Se incluyeron pacientes ingresados por exacerbación de EPOC que aceptaron participar y que firmaron consentimiento informado. Se consideró evolución desfavorable la estancia prolongada, la mortalidad hospitalaria o el reingreso precoz. También se analizó la mortalidad a 30 días. Resultados: Se incluyeron 615 pacientes. La edad media fue 73,9 años (DE 10,6); El 86,2% eran varones. Se consideró desfavorable la evolución de 357 pacientes (58%). La mortalidad al mes del alta fue del 6,7%. El análisis multivariante muestra una relación entre el ratio PCR/Albúmina y la progresión desfavorable (OR 1,008, IC 95% 1,00; 1,01), así como un mayor riesgo de muerte al mes del alta con urea elevada (OR 1,01, IC 95% 1,005; 1,02) y troponina T (OR 2,21; IC del 95%: 1,06; 4,62). Conclusión: La elevación de PCR/albúmina, la urea y la TnT son indicadores de mal pronóstico a corto plazo en pacientes ingresados por exacerbación de la EPOC. La comorbilidad cardiovascular y la inflamación sistémica podrían explicar estos hallazgos.

Variability of blood eosinophil count and prognosis of COPD exacerbations.

BACKGROUND: Eosinophils in peripheral blood are one of the emerging biomarkers in chronic obstructive pulmonary disease (COPD) patients. However, when analysing the relationship between peripheral eosinophilia and COPD prognosis, highly variable results are obtained. The aim of our study is to describe the serum eosinophilia levels in COPD patients and to analyse their relationship to prognosis following hospital admission. METHODS: A prospective observational study was conducted from 1 October 2016 to 1 October 2018 in the following Spanish centres: Salnés County Hospital in Vilagarcía de Arousa, Arquitecto Marcide Hospital in Ferrol and the University Hospital Complex in Santiago de Compostela. The patients were classified using three cut-off points of blood eosinophil count (BEC): 150 cells/µL, 300 cells/µL, and 400 cells/µL; in addition, the peripheral BEC was analysed on admission. RESULTS: 615 patients were included in the study, 86.2% male, mean age 73.9 years, and mean FEV1 52.7%. The mean stay was 8.4 days, and 6% of all patients were readmitted early. No significant relationship was observed between the BEC, neither in the stable phase nor in the acute phase, and hospital stay, readmissions, deaths during admission, the need for intensive care, or the condition of frequent exacerbator. CONCLUSION: The results of our study do not seem to support the usefulness of BEC as a COPD biomarker.KEY MESSAGESThere is evidence that BEC participates in pathophysiological mechanisms of the COPD.BEC may be useful as a biomarker in COPD for aspects such as the optimization of treatments.We did not find any relationship between BEC levels and prognosis following hospital admission for AECOPD.

Impact of Hyponatremia on COPD Exacerbation Prognosis.

The most common electrolyte disorder among hospitalized patients, hyponatremia is a predictor of poor prognosis in various diseases. The aim of this study was to establish the prevalence of hyponatremia in patients admitted for acute exacerbation of chronic obstructive pulmonary disease (AECOPD), as well as its association with poor clinical progress. Prospective observational study carried out from 1 October 2016 to 1 October 2018 in the following hospitals: Salnés in Vilagarcía de Arousa, Arquitecto Marcide in Ferrol, and the University Hospital Complex of Santiago de Compostela, Galicia, Spain, on patients admitted for AECOPD. Patient baseline treatment was identified, including hyponatremia-inducing drugs. Poor progress was defined as follows: prolonged stay, death during hospitalization, or readmission within one month after the index episode discharge. 602 patients were enrolled, 65 cases of hyponatremia (10.8%) were recorded, all of a mild nature (mean 131.6; SD 2.67). Of all the patients, 362 (60%) showed poor progress: 18 (3%) died at admission; 327 (54.3%) had a prolonged stay; and 91 (15.1%) were readmitted within one month after discharge. Patients with hyponatremia had a more frequent history of atrial fibrillation (AF) (p 0.005), pleural effusion (p 0.01), and prolonged stay (p 0.01). The factors independently associated with poor progress were hyponatremia, pneumonia, and not receiving home O2 treatment prior to admission. Hyponatremia is relatively frequent in patients admitted for AECOPD, and it has important prognostic implications, even when mild in nature.

Obesity Does Not Increase the Risk of Asthma Readmissions.

The relationship between obesity and asthma exacerbations is still under debate. The aim of our work is to analyse the relationship between obesity and hospital re-admissions in asthmatics. A review was retrospectively performed on all hospital admissions of adult patients due to asthma exacerbation occurring in our hospital for 11 years. All those cases with asthma as the first diagnosis in the discharge report were included, or those with asthma as the second diagnosis provided when the first diagnosis was respiratory infection or respiratory failure. Only the first hospital admission of each patient was included in this study. The Odds Ratios of a higher incidence of early/late readmissions due to asthma exacerbation were calculated using a binary logistic regression, using the body mass index (BMI) as independent variable, adjusted for all the variables included in the study. The study included 809 patients with a mean age of 55.6 years, and 65.2% were female. The majority (71.4%) were obese or overweight. No significant relationship was observed in the univariate or multivariate analyses between overweight or obesity and the early or late hospital readmissions due to asthma. Therefore, obesity does not seem to be a determining factor in the risk of asthma exacerbations.

Prolonged stay predictors in patients admitted with chronic obstructive pulmonary disease acute exacerbation.

OBJECTIVES: The study aimed to identify the factors related to prolonged stay in those patients admitted with acute exacerbations of chronic obstructive pulmonary disease (AECOPD) to our hospital. METHODS: We conducted a retrospective study by reviewing the medical records of all patients admitted with AECOPD to the University Hospital Complex of Santiago de Compostela in 2007 and 2008. To identify variables independently associated with length of stay, we conducted a logistic regression including those variables which proved to be significant in the univariate analysis. RESULTS: Six hundred and sixty-one patients were assessed; 76.6% were male and the mean age was 74.5 years (standard deviation [SD]: 11.48). The mean stay was 11.9 days (SD: 8) and 24% of all patients required prolonged stay. Factors associated with prolonged mean stay in multivariate analysis were admission to the Intensive Care Unit (odds ratio [OR], 14.7), hospitalization by internal medicine (OR, 2.1), and use of noninvasive mechanical ventilation (OR, 1.75). CONCLUSIONS: Prolonged stay in AECOPD is primarily related to the unit patients are admitted to, and to the need for more intensive care.

Association between blood eosinophil count with asthma hospital readmissions.

INTRODUCTION: The presence of eosinophils in asthma inflammation is a relevant factor in the pathophysiology of the disease, however the relationship between the blood eosinophil count (BEC) with asthma severity and prognosis is still under debate. The aim of this work is to analyze the relationship between the BEC levels and hospital readmissions in patients with asthma. MATERIAL AND METHODS: A review was retrospectively carried out on all admissions of patients over 18 years old due to exacerbation of asthma occurring in our hospital between the years 2000 and 2010. The personal characteristics and the asthma personal history of each patient were recorded. The BEC was determined from the first blood sample taken from the patient after their arrival at the hospital. Hospital early, late and frequent readmissions were analyzed using 4 cut-off points; less than 150 eosinophils/µL vs ≥150/µL, less than 200 vs 200 /µL, less than 300 vs ≥300/µL, and less than 400 vs ≥400/µL. RESULTS: We have included 1316 patients, 70% of whom are women, as well as a mean age of 60 years, and a mean FEV1 of 73.5% of the reference value. The mean eosinophil blood count was 201.7 cells/µL. A BEC ≥300 cells/µL showed a reduction of risk of late readmission of 42%, a BEC ≥400 cells/µL showed a reduction in late readmission risk of 41% and decrease in frequent late readmission of 63%. CONCLUSIONS: Our study appears to support that an elevated BEC is associated with a lower incidence of asthma hospital readmissions.

One-year and long-term mortality in patients hospitalized for chronic obstructive pulmonary disease.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. Identifying potentially-modifiable predictors of mortality could help optimize COPD patient management. The aim of this study is to determine long-term mortality following hospitalization due to acute exacerbations of COPD (AECOPD), as well as AECOPD mortality predictors. METHODS: We conducted a retrospective study by reviewing the medical records of all patients admitted with AECOPD in the University Hospital Complex of Santiago de Compostela in 2007 and 2008. In order to identify variables independently associated with mortality, we conducted a multivariate Cox proportional hazard regression analysis including those variables which proved to be significant in the univariate analysis. RESULTS: Seven hundred and fifty seven patients were assessed. Patient mean age was 74.8 years and males accounted for 77% of all patients. Mean stay was 12.2 days. Three point six percent of all patients required intensive care. As for mortality rates, 1-year mortality was 26.2%, and 5-year mortality was 64.3%. In both scenarios, the most frequent causes of death were respiratory and cardiovascular disorders. Factors independently associated with mortality were older age, hospitalization by internal medicine (IMU), length of stay, the need for mechanical ventilation (MV) or noninvasive mechanical ventilation (NIV), early readmission, and history of atrial fibrillation (AF) and dementia. CONCLUSIONS: In patients with COPD, age, exacerbation severity and comorbidity have long-term prognostic significance.

Asthma exacerbations: factors related to longer hospital stay.

BACKGROUND: Hospital admissions account for a significant part of asthma cost, but with significant differences between geographic areas. AIMS: The aim of our study is to analyse hospital admissions due to asthma, as well as the factors associated with longer hospital stays. METHODS: A review was retrospectively carried out on all admissions of patients over 18 years old due to exacerbation of asthma occurring in our hospital between the years 2000 and 2010. The personal characteristics of each patient, the asthma personal history, characteristics of every exacerbation, as well as the treatment before admission and after hospital discharge were recorded. RESULTS: During the study period, there were 2163 hospital admissions in 1316 patients (mean age 62.6 years; mean hospital stay 11.6 days). The admissions mainly occur in winter, in the 56-75-year age group, and in patients with severe asthma. Female sex, higher comorbidity, a greater number of emergencies due to asthma in the previous year, and baseline treatment with theophylline were independently associated to longer hospital stay. CONCLUSIONS: The management of asthma in our population seems improvable. There appears to be a need to optimise both the diagnosis and treatment of the disease, and to identify risk factors as important as tobacco habits. As regards exacerbations, the hospital stay and mortality must be significantly reduced.

Characteristics and prognosis of near-fatal asthma exacerbations.

BACKGROUND: Asthma remains a major public health concern because of its high prevalence and the costs it generates. Near-fatal asthma (NFA) episodes represent the most severe forms of the disease after fatal asthma with significant variations in their incidence between different populations. OBJECTIVE: To analyze the episodes of NFA over a period of 11 years in the hospital. METHODS: The authors retrospectively reviewed all admissions due to asthma exacerbation in our hospital between 2000 and 2010 for patients over 18 years of age. RESULTS: The study included 400 NFA episodes of 285 patients (74% women; mean age 66 years). Of these patients, 228 (80%) had a single episode of NFA and 57 had more than 1 episode during the study period. The authors observed no clear upward or downward trend during the study period. Readmitted patients had more comorbidities, poorer lung function, more severe forms of asthma and more admissions in the year before the index admission. There was a mortality rate of 3.1%. More than 20% of patients were not given controller treatment and more than 40% of patients were not treated with inhaled corticosteroids (ICS). CONCLUSIONS: NFA episodes are still prevalent in the population of patients with asthma. Reasons for this could be related to improper management in the stable phase, as suggested by the low rate of patients treated with ICS. It also seems necessary to optimize patient management during hospitalization because stays appear prolonged in comparison with studies in other countries.

Symptoms and reason for a medical visit in lung cancer patients.

BACKGROUND: Patients with lung cancer usually present with symptoms at the time of diagnosis, but it is common that neither the doctor nor the patient initially associate them with the possibility of a malignant tumour. OBJECTIVES: The aim of our study is to analyse the symptoms of patients with lung cancer and the relationship with the personal characteristics or the oncological disease. MATERIAL AND METHODS: A retrospective study was conducted on all patients diagnosed with lung cancer in the Pontevedra Health Area over a period of three years. The symptoms presented by the patient, the reason for the consultation and the agreement between both or any factors associated with either of the two are analysed. RESULTS: A total of 358 patients, with a mean age of 68.7 years, and of whom 87% males, were included in the study. The most common initial symptoms were, constitutional in 30.4% of the cases, cough in 20.9% of cases, and in third place was chest pain, which was referred to by 12% of the patients. The most frequent reason for the consultation was dyspnea in 22.1% of patients, an incidental finding in 15.4%, and haemoptysis in 12.8%. There was a moderate association (correlation coefficient = 0.495) between the initial symptoms and the consulting symptom. CONCLUSIONS: A high percentage of patients with lung cancer had symptoms associated with the tumour at the time of diagnosis, even in early stage disease.

Contexto: A Os doentes com o diagnóstico de cancro do pulmão estão habitualmente sintomáticos no momento do diagnóstico, sendo comum que o médico ou o doente não associem essa sintomatologia com a eventualidade de um tumor maligno. Objectivos: Este estudo teve como objectivo a análise dos sintomas de doentes com cancro do pulmão e sua relação com as características pessoais ou com a doença oncológica. Material e Métodos: Foi levado a cabo um estudo retrospectivo englobando todos os doentes com o diagnóstico de cancro do pulmão na Região de Saúde de Pontevedra (Espanha) ao longo de um período de três anos. São analisados os sintomas de apresentação do doente, o motivo de consulta e a concordância entre ambos ou com quaisquer factores correlacionados. Resultados: Foram incluídos no estudo 358 doentes, com uma média etária de 68,7 anos, sendo 87% dos doentes do sexo masculino. Os sintomas iniciais mais comuns foram sintomas constitucionais em 30,4% dos casos, tosse em 20,9% e dor torácica, descrita por 12% dos doentes. O motivo de consulta mais frequente foi dispneia em 22,1% dos doentes, um achado acidental em 15,4% dos doentes e hemoptise em 12,8%. Observou-se uma associação moderada (coeficiente de correlação = 0,495) entre os sintomas iniciais e o motivo de consulta. Conclusões: Uma elevada percentagem de doentes com um diagnóstico de cancro do pulmão apresentou sintomas associados com o tumor no momento do diagnóstico, mesmo num estadio inicial da doença.

Factors associated with hospital admission in patients reaching the emergency department with COPD exacerbation.

BACKGROUND: The aim of this study was to determine the frequency of COPD exacerbations in our Emergency Department, as well as the hospitalization-related factors. METHODS: Prospective observational study conducted in the Emergency Department of Salnés County Hospital among patients admitted for COPD exacerbation. Admission predictors were determined by multivariate analysis. RESULTS: There were 409 exacerbations in 239 patients (79% male, mean age 75). 57% of exacerbations required hospitalization. Hospitalization-related factors were impaired oxygenation (p < 0.001), presence of neutrophilia (p < 0.01) and prescription of antibiotics in the Emergency Department (p < 0.05). CONCLUSIONS: COPD exacerbation accounts for over 1% of all visits to our Emergency Department. 57% of them required hospitalization. Impaired oxygenation, greater neutrophilia and prescription of antibiotics in the Emergency Department were associated with greater probability of admission.

Trends in adult asthma hospitalization: gender-age effect.

BACKGROUND: Hospital admissions due to asthma are a reliable source of information on the morbidity of the disease which, after the increase observed in the last quarter of the last century, shows a declining trend in the last few years. The aim of this study was to look at hospital admission trends due to asthma in our community and analyze some of its associated factors. METHODS: Retrospective analysis of all hospital admissions involving adults aged 15 years and older with asthma as the primary or secondary diagnosis (if the first diagnosis was respiratory failure or respiratory infection) in Public Health Service hospitals in the Galician region of Spain between the years 1995-2009 (total 24,766 admissions). RESULTS: The majority of patients admitted were female (71%), over 60 years of age (64%), and admission occurred predominantly in the winter months. The hospitalization rate due to asthma tripled over the period studied, this being mainly accounted for by women aged over 60 years. Mean hospital stay was 9.2 days, longer in older patients or those admitted over the weekend. CONCLUSIONS: A significant increase in hospital admissions due to asthma over the last few years has been observed in our community, mainly involving older women. The mean stay seems long, increasing with patients' age and admission over the weekend.

Effect of delays on survival in patients with lung cancer.

BACKGROUND: The effect on survival of delays in the consultation, diagnostic and treatment processes of lung cancer (LC) is still under debate. The objective of our study was to analyse these time delays and their possible effect on survival. METHODS: A retrospective study has been performed on all patients in our health area diagnosed with LC (confirmed by cytohistology) over 3 years. The delay in specialist consultation (time between start of symptoms and the first consultation with a specialist), hospital delay (time between first consultation and start of treatment) and overall delay (the sum of the previous two delays) were analysed. The influence of each of these delays was calculated using Cox regression, adjusted for other factors. RESULTS: A total of 415 patients were included. Of these, 92.5% were male and 75.4% were in stages III-B or IV. The overall delay gave a mean of 123.6 days, the delay in consulting a specialist 82.1 days and the delay in hospitalisation was 41.4 days. A greater overall delay or greater hospital delay was associated with longer survival. No relationship was observed between the specialist consultation delay and survival. CONCLUSIONS: Globally analysing all the cases and all the stages with LC, it is seen that longer delays are associated with longer survival. This probably reflects the fact that patients with more symptoms are treated more rapidly.
