Seasonal variability in clinical care of COPD outpatients: results from the Andalusian COPD audit.

OBJECTIVES: Clinical practice in chronic obstructive pulmonary disease (COPD) can be influenced by weather variability throughout the year. To explore the hypothesis of seasonal variability in clinical practice, the present study analyzes the results of the 2013-2014 Andalusian COPD audit with regard to changes in clinical practice according to the different seasons. METHODS: The Andalusian COPD audit was a pilot clinical project conducted from October 2013 to September 2014 in outpatient respiratory clinics of hospitals in Andalusia, Spain (8 provinces with more than 8 million inhabitants) with retrospective data gathering. For the present analysis, astronomical seasons in the Northern Hemisphere were used as reference. Bivariate associations between the different COPD guidelines and the clinical practice changes over the seasons were explored by using binomial multivariate logistic regression analysis with age, sex, Charlson comorbidity index, type of hospital, and COPD severity by forced expiratory volume in 1 second as covariates, and were expressed as odds ratio (OR) with 95% confidence intervals (CIs). RESULTS: The Andalusian COPD audit included 621 clinical records from 9 hospitals. After adjusting for covariates, only inhaler device satisfaction evaluation was found to significantly differ according to the seasons with an increase in winter (OR, 3.460; 95% CI, 1.469-8.151), spring (OR, 4.215; 95% CI, 1.814-9.793), and summer (OR, 3.371; 95% CI, 1.391-8.169) compared to that in autumn. The rest of the observed differences were not significant after adjusting for covariates. However, compliance with evaluating inhaler satisfaction was low. CONCLUSION: The various aspects of clinical practice for COPD care were found to be quite homogeneous throughout the year for the variables evaluated. Inhaler satisfaction evaluation, however, presented some significant variation during the year. Inhaler device satisfaction should be evaluated during all clinical visits throughout the year for improved COPD management.

Determinants for changing the treatment of COPD: a regression analysis from a clinical audit.

INTRODUCTION: This study is an analysis of a pilot COPD clinical audit that evaluated adherence to guidelines for patients with COPD in a stable disease phase during a routine visit in specialized secondary care outpatient clinics in order to identify the variables associated with the decision to step-up or step-down pharmacological treatment. METHODS: This study was a pilot clinical audit performed at hospital outpatient respiratory clinics in the region of Andalusia, Spain (eight provinces with over eight million inhabitants), in which 20% of centers in the area (catchment population 3,143,086 inhabitants) were invited to participate. Treatment changes were evaluated in terms of the number of prescribed medications and were classified as step-up, step-down, or no change. Three backward stepwise binominal multivariate logistic regression analyses were conducted to evaluate variables associated with stepping up, stepping down, and inhaled corticosteroids discontinuation. RESULTS: The present analysis evaluated 565 clinical records (91%) of the complete audit. Of those records, 366 (64.8%) cases saw no change in pharmacological treatment, while 99 patients (17.5%) had an increase in the number of drugs, 55 (9.7%) had a decrease in the number of drugs, and 45 (8.0%) noted a change to other medication for a similar therapeutic scheme. Exacerbations were the main factor in stepping up treatment, as were the symptoms themselves. In contrast, rather than symptoms, doctors used forced expiratory volume in 1 second and previous treatment with long-term antibiotics or inhaled corticosteroids as the key determinants to stepping down treatment. CONCLUSION: The majority of doctors did not change the prescription. When changes were made, a number of related factors were noted. Future trials must evaluate whether these therapeutic changes impact clinically relevant outcomes at follow-up.

Guideline Adherence in Outpatient Clinics for Chronic Obstructive Pulmonary Disease: Results from a Clinical Audit.

OBJECTIVES: Previous clinical audits of COPD have provided relevant information about medical intervention in exacerbation admissions. The present study aims to evaluate adherence to current guidelines in COPD through a clinical audit. METHODS: This is a pilot clinical audit performed in hospital outpatient respiratory clinics in Andalusia, Spain (eight provinces with more than 8 million inhabitants), including 9 centers (20% of the public centers in the area) between 2013 and 2014. Cases with an established diagnosis of COPD based on risk factors, clinical symptoms, and a post-bronchodilator FEV1/FVC ratio of less than 0.70 were deemed eligible. The performance of the outpatient clinics was benchmarked against three guidance documents available at the time of the audit. The appropriateness of the performance was categorized as excellent (>80%), good (60-80%), adequate (40-59%), inadequate (20-39%), and highly inadequate (<20%). RESULTS: During the audit, 621 clinical records were audited. Adherence to the different guidelines presented a considerable variability among the different participating hospitals, with an excellent or good adherence for symptom recording, MRC or CAT use, smoking status evaluation, spirometry, or bronchodilation therapy. The most outstanding areas for improvement were the use of the BODE index, the monitoring of treatments, the determination of alpha1-antitrypsin, the performance of exercise testing, and vaccination recommendations. CONCLUSIONS: The present study reflects the situation of clinical care for COPD patients in specialized secondary care outpatient clinics. Adherence to clinical guidelines shows considerable variability in outpatient clinics managing COPD patients, and some aspects of the clinical care can clearly be improved.

Modelo predictivo de ansiedad y depresión en pacientes españoles con enfermedad pulmonar obstructiva crónica estable / Predictive Model for Anxiety and Depression in Spanish Patients with Stable Chronic Obstructive Pulmonary Disease

Introducción: La asociación entre la enfermedad pulmonar obstructiva crónica (EPOC) y la ansiedad o la depresión no se conoce adecuadamente, y puede haber diferencias entre distintos países. Investigamos un modelo predictivo para esta asociación en una población española. Pacientes y método: Estudio prospectivo descriptivo transversal incluyendo 204 pacientes con EPOC estable. Se diagnostica la presencia de ansiedad o depresión mediante valoración psiquiátrica, aplicando los criterios diagnósticos de la 10.ª revisión del International Statistical Classification of Diseases and Related Health Problems (ICD-10). Se analizan variables sociodemográficas, clínicas y de función pulmonar. Resultados: Un 36% de pacientes con EPOC estable tienen comorbilidad psiquiátrica, pero en el 76% de los casos se desconocía dicho diagnóstico. Presentan un trastorno de ansiedad pura el 19%, depresión aislada el 9,8% y un trastorno mixto de ansiedad y depresión el 7,3% de los pacientes. En el análisis multivariante las variables predictoras son: edad más joven, mayor nivel de estudios, falta de apoyo domiciliario, mayor índice de BODE y mayor número de agudizaciones. La curva ROC del modelo muestra un AUC de 0,765 (p<0,001). Conclusiones: En la EPOC, una mayoría de pacientes con comorbilidad psiquiátrica no son identificados. Los trastornos de ansiedad son más frecuentes que la depresión, en base a un diagnóstico mediante entrevista estructurada. Los pacientes más jóvenes y con mayor nivel de estudios tienen más riesgo de de padecer ansiedad o depresión. Otros factores predictivos son: un mayor índice BODE, más agudizaciones y la falta de apoyo domiciliario

Introduction: The association between chronic obstructive pulmonary disease (COPD) and anxiety and depression is not yet completely characterized, and differences between countries may exist. We used a predictive model to assess this association in a Spanish population. Patients and method: Prospective transversal descriptive study of 204 patients with stable COPD. Concomitant anxiety or depression were diagnosed by psychiatric assessment, using the diagnostic criteria of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). Sociodemographic, clinical and lung function parameters were analyzed. Results: In total, 36% of stable COPD patients had psychiatric comorbidities, but 76% were unaware of their diagnosis. Nineteen percent had a pure anxiety disorder, 9.8% had isolated depression, and 7.3% had a mixed anxiety-depression disorder. Predictive variables in the multivariate analysis were younger age, higher educational level, lack of home support, higher BODE index, and greater number of exacerbations. The ROC curve of the model had an AUC of 0.765 (P<0.001). Conclusions: In COPD, concomitant psychiatric disorders are significantly associated with sociodemographic factors. Anxiety disorders are more common than depression. Patients with more severe COPD, according to BODE, younger patients and those with a higher educational level have a greater risk of being diagnosed with anxiety or depression in a structured psychiatric interview. In our population, most patients with psychiatric comorbidities remain unidentified

Clinical Audits in Outpatient Clinics for Chronic Obstructive Pulmonary Disease: Methodological Considerations and Workflow.

OBJECTIVES: Previous clinical audits for chronic obstructive pulmonary disease (COPD) have provided valuable information on the clinical care delivered to patients admitted to medical wards because of COPD exacerbations. However, clinical audits of COPD in an outpatient setting are scarce and no methodological guidelines are currently available. Based on our previous experience, herein we describe a clinical audit for COPD patients in specialized outpatient clinics with the overall goal of establishing a potential methodological workflow. METHODS: A pilot clinical audit of COPD patients referred to respiratory outpatient clinics in the region of Andalusia, Spain (over 8 million inhabitants), was performed. The audit took place between October 2013 and September 2014, and 10 centers (20% of all public hospitals) were invited to participate. Cases with an established diagnosis of COPD based on risk factors, clinical symptoms, and a post-bronchodilator FEV1/FVC ratio of less than 0.70 were deemed eligible. The usefulness of formally scheduled regular follow-up visits was assessed. Two different databases (resources and clinical database) were constructed. Assessments were planned over a year divided by 4 three-month periods, with the goal of determining seasonal-related changes. Exacerbations and survival served as the main endpoints. CONCLUSIONS: This paper describes a methodological framework for conducting a clinical audit of COPD patients in an outpatient setting. Results from such audits can guide health information systems development and implementation in real-world settings.
