Chronic obstructive pulmonary disease (COPD) remains a major public health problem. It is the fourth leading cause of chronic morbidity and mortality in the United States, and is projected to rank fifth in 2020 in burden of disease worldwide, according to a study published by the World Bank/World Health Organization. Yet, COPD remains relatively unknown or ignored by the public as well as public health and government officials. In 1998, in an effort to bring more attention to COPD, its management, and its prevention, a committed group of scientists encouraged the U.S. National Heart, Lung, and Blood Institute and the World Health Organization to form the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Among the important objectives of GOLD are to increase awareness of COPD and to help the millions of people who suffer from this disease and die prematurely of it or its complications. The first step in the GOLD program was to prepare a consensus report, Global Strategy for the Diagnosis, Management, and Prevention of COPD, published in 2001. The present, newly revised document follows the same format as the original consensus report, but has been updated to reflect the many publications on COPD that have appeared. GOLD national leaders, a network of international experts, have initiated investigations of the causes and prevalence of COPD in their countries, and developed innovative approaches for the dissemination and implementation of COPD management guidelines. We appreciate the enormous amount of work the GOLD national leaders have done on behalf of their patients with COPD. Despite the achievements in the 5 years since the GOLD report was originally published, considerable additional work is ahead of us if we are to control this major public health problem. The GOLD initiative will continue to bring COPD to the attention of governments, public health officials, health care workers, and the general public, but a concerted effort by all involved in health care will be necessary.

Global strategy for the diagnosis, management, and prevention of chronic obstructive pulmonary disease: GOLD executive summary.

OBJECTIVE — To systematically review the incidence of posttransplantation diabetes (PTD), risk factors for its development, prognostic implications, and optimal management. RESEARCH DESIGN AND METHODS — We searched databases (MEDLINE, EMBASE, the Cochrane Library, and others) from inception to September 2000, reviewed bibliographies in reports retrieved, contacted transplantation experts, and reviewed specialty journals. Two reviewers independently determined report inclusion (original studies, in all languages, of PTD in adults with no history of diabetes before transplantation), assessed study methods, and extracted data using a standardized form. Meta-regression was used to explain between-study differences in incidence. RESULTS — Nineteen studies with 3,611 patients were included. The 12-month cumulative incidence of PTD is lower (10% in most studies) than it was 3 decades ago. The type of immunosuppression explained 74% of the variability in incidence (P 0.0004). Risk factors were patient age, nonwhite ethnicity, glucocorticoid treatment for rejection, and immunosuppression with high-dose cyclosporine and tacrolimus. PTD was associated with decreased graft and patient survival in earlier studies; later studies showed improved outcomes. Randomized trials of treatment regimens have not been conducted. CONCLUSIONS — Physicians should consider modification of immunosuppressive regimens to decrease the risk of PTD in high-risk transplant recipients. Randomized trials are needed to evaluate the use of oral glucose-lowering agents in transplant recipients, paying particular attention to interactions with immunosuppressive drugs.

This new edition of Ann Bowling's well-known and highly respected text has been thoroughly revised and updated to reflect key methodological developments in health research. It is a comprehensive, easy to read, guide to the range of methods used to study and evaluate health and health services. It describes the concepts and methods used by the main disciplines involved in health research, including: demography, epidemiology, health economics, psychology and sociology.The research methods described cover the assessment of health needs, morbidity and mortality trends and rates, costing health services, sampling for survey research, cross-sectional and longitudinal survey design, experimental methods and techniques of group assignment, questionnaire design, interviewing techniques, coding and analysis of quantitative data, methods and analysis of qualitative observational studies, and types of unstructured interviewing. With new material on topics such as cluster randomization, utility analyses, patients' preferences, and perception of risk, the text is aimed at students and researchers of health and health services. It has also been designed for health professionals and policy makers who have responsibility for applying research findings in practice, and who need to know how to judge the value of that research.

Research Methods in Health. Investigating health and health services

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterised by both an accelerated decline in lung function and periods of acute deterioration in symptoms termed exacerbations. The aim of this study was to investigate whether these are related. METHODS: Over 4 years, peak expiratory flow (PEF) and symptoms were measured at home daily by 109 patients with COPD (81 men; median (IQR) age 68.1 (63-74) years; arterial oxygen tension (PaO(2)) 9.00 (8.3-9.5) kPa, forced expiratory volume in 1 second (FEV(1)) 1.00 (0.7-1.3) l, forced vital capacity (FVC) 2.51 (1.9-3.0) l); of these, 32 (29 men) recorded daily FEV(1). Exacerbations were identified from symptoms and the effect of frequent or infrequent exacerbations (> or < 2.92 per year) on lung function decline was examined using cross sectional, random effects models. RESULTS: The 109 patients experienced 757 exacerbations. Patients with frequent exacerbations had a significantly faster decline in FEV(1) and peak expiratory flow (PEF) of -40.1 ml/year (n=16) and -2.9 l/min/year (n=46) than infrequent exacerbators in whom FEV(1) changed by -32.1 ml/year (n=16) and PEF by -0.7 l/min/year (n=63). Frequent exacerbators also had a greater decline in FEV(1) if allowance was made for smoking status. Patients with frequent exacerbations were more often admitted to hospital with longer length of stay. Frequent exacerbations were a consistent feature within a patient, with their number positively correlated (between years 1 and 2, 2 and 3, 3 and 4). CONCLUSIONS: These results suggest that the frequency of exacerbations contributes to long term decline in lung function of patients with moderate to severe COPD.

Relationship between exacerbation frequency and lung function decline in chronic obstructive pulmonary disease

Resumen Objetivo Conocer la accesibilidad y la utilizacion de la espirometria forzada (EF) en los dispositivos publicos de atencion primaria en Cataluna. Diseno Estudio transversal mediante encuesta. Participantes Trescientos sesenta y seis equipos de atencion primaria (EAP) de Cataluna. Tercer trimestre de 2010. Mediciones Encuesta con informacion relativa a los espirometros, la formacion, la interpretacion y el control de calidad, y el grado de prioridad que la calidad de la espirometria tenia para el equipo. Se analizaron: media de EF/100 habitantes/ano; indice de EF/mes/EAP; indice de EF/mes/10.000 habitantes. Resultados principales Porcentaje de respuesta: 75%. El 97,5% de los EAP dispone de espirometro y realiza una media de 2,01 espirometrias/100 habitantes (34,68 espirometrias/EAP/mes). El 83% dispone de profesionales formados y mas del 50% de los centros realizan formacion reglada, pero no se dispone de informacion sobre la calidad de la misma. En el 70% se hace algun tipo de calibracion. La interpretacion la realiza el medico de familia en el 87,3% de los casos. En el 68% de los casos no se lleva a cabo ningun tipo de control de calidad de la exploracion. En dos tercios de los casos se introducen manualmente los datos en la historia clinica informatiza. Mas del 50% se atribuye una prioridad alta para las estrategias de mejora de la calidad de la EF. Conclusiones A pesar de la accesibilidad a la EF deben realizarse esfuerzos para estandarizar la formacion, incrementar el numero de exploraciones y promover el control de calidad sistematico.

The potential of forced spirometry (FS) testing for diagnosis, monitoring and management of chronic respiratory patients is well established1-3 such that FS is a pivotal test in both respiratory medicine and primary care. Moreover, it also shows potential in the informal care scenario: that is, in pharmacy offices for case-finding purposes4,5 and for self-management in selected patients.6,7 We acknowledge that well-designed studies8 have failed to show practical benefits of FS for asthma and COPD diagnosis and management in primary care. However, it has been demonstrated that historical limitations for extensive use of FS in primary care, because of suboptimal quality of testing, can be overcome by offline remote support by specialised professionals.9,10 Large-scale deployment of this type of setting has generated evidence of cost-effectiveness..

Introduction Home oxygen therapy has a great impact on the lives of patients and their families. The aim of this study is to define the opinions, perceptions and attitudes of patients and their caregivers regarding home oxygen. Method Qualitative, phenomenological study of a sample of 57 subjects, consisting of 18 family members and/or caregivers and 39 patients receiving home oxygen in urban centers. Five focus groups were formed between March and July 2014 in hospitals in Barcelona, Madrid and Alicante. Prior informed consent was obtained from patients and families. The study material consisted of audio recordings of all focus group interviews, transcription of selected materials and field notes. Data analysis was performed using constant comparison method, establishing 2 levels of analysis. Results Data from the focus groups were analyzed on 2 levels. A first level of analysis gave 21 categories. In a second level of analysis, these were integrated into 6 meta-categories: care provided by health professionals, psychological impact, care provided by commercial companies, impact on daily life, problems and satisfaction. Conclusions Home oxygen has a major psychological impact on the daily lives of both patients and their families, and can cause social isolation. Although the results show that healthcare professionals are highly appreciated, better coordination is needed between different levels of care and companies supplying oxygen in order to provide patients and families with consistent information and useful strategies.
