Abstract
Background Statistical models are increasingly being used to estimate and project the prevalence and burden of asthma. Given substantial variations in these estimates, there is a need to critically assess the properties of these models and assess their transparency and reproducibility. We aimed to critically appraise the strengths, limitations and reproducibility of existing models for estimating and projecting the global, regional and national prevalence and burden of asthma. Methods We undertook a systematic review, which involved searching Medline, Embase, World Health Organization Library and Information Services (WHOLIS) and Web of Science from 1980 to 2017 for modelling studies. Two reviewers independently assessed the eligibility of studies for inclusion and then assessed their strengths, limitations and reproducibility using pre-defined quality criteria. Data were descriptively and narratively synthesised. Results We identified 108 eligible studies, which employed a total of 51 models: 42 models were used to derive national level estimates, two models for regional estimates, four models for global and regional estimates and three models for global, regional and national estimates. Ten models were used to estimate the prevalence of asthma, 27 models estimated the burden of asthma – including, health care service utilisation, disability-adjusted life years, mortality and direct and indirect costs of asthma – and 14 models estimated both the prevalence and burden of asthma. Logistic and linear regression models were most widely used for national estimates. Different versions of the DisMod-MR- Bayesian meta-regression models and Cause Of Death Ensemble model (CODEm) were predominantly used for global, regional and national estimates. Most models suffered from a number of methodological limitations – in particular, poor reporting, insufficient quality and lack of reproducibility. Conclusions Whilst global, regional and national estimates of asthma prevalence and burden continue to inform health policy and investment decisions on asthma, most models used to derive these estimates lack the required reproducibility. There is a need for better-constructed models for estimating and projecting the prevalence and disease burden of asthma and a related need for better reporting of models, and making data and code available to facilitate replication.

Oshagbemi OA, Keene SJ, Driessen JHM, Jordan R, Wouters EFM, de Boer A, de Vries F, Franssen FME. Trends in moderate and severe exacerbations among COPD patients in the UK from 2005 to 2013. Respir Med 2018; 144:1-6. [PMID: 30366578 DOI: 10.1016/j.rmed.2018.09.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2018] [Revised: 09/04/2018] [Accepted: 09/11/2018] [Indexed: 10/28/2022]
Abstract
INTRODUCTION Exacerbations of chronic obstructive pulmonary disease are characterised by increased symptoms such as dyspnoea, cough and sputum production and/or purulence, leading to greater risk of hospitalisation and mortality. Very few studies have measured long term trends in the incidence of exacerbations of chronic obstructive pulmonary disease. We therefore investigated the incidence of moderate and severe exacerbations in the UK general population. METHODS A population based-study including Clinical Practice Research Datalink (CPRD) patients ≥ 40 years of age with a current diagnosis of COPD within the United Kingdom from 2004 to 2013 was conducted. Individuals with a history of asthma were excluded from main analyses. We calculated the incidence rates for any, moderate, and severe exacerbations. Patients contributed time at risk from January 1st up to the date of the first outcome within each year. The incidence rate for any, moderate and severe exacerbations for COPD in each calendar year was calculated as follows: the sum of any or moderate or severe exacerbations for COPD in that year divided by the total duration of follow-up in the same calendar year from 2005 through to 2013. We then analysed these rates by gender and age categories (40-59 years, 60-79 years and ≥80 years). RESULTS Among 213,561 with incident COPD diagnosis, 86,300 patients were included in the study. From 2005 to 2013, the incidence rate of any exacerbations increased from 89 to 98 per 1000 person years (PYs) (p = 0.005). Women had significantly higher incidence rates of any exacerbation for each calendar year when compared to men (p < 0.0001). The incidence rate of any and moderate exacerbations increased with age from 2005 to 2007. For severe exacerbations incidence decreased from 2005 to 2007 before increasing from 2008 until the end of follow-up (43 per 1000 PYs (95% confidence interval, 42-45/1000PYs) in 2013). Incidence rates of severe exacerbations were similar by gender and patients aged 80 + years had a higher incidence rate of severe exacerbation from 2005 to 2008 after which their incident rate dropped in subsequent years. CONCLUSION This is the first study that reports the long-term changes in the incidence rates of moderate and severe exacerbations within the UK general practice. Women showed a substantially higher risk of any COPD exacerbations, and their risk is increasing. The incidence rates of any exacerbations increased during the study period, while severe exacerbations were variable. Furthermore, incidence rates varied substantially by age group.

Abstract
OBJECTIVE To describe the rate of ambulatory care sensitive hospitalizations in groups of cities according to population size and to analyze its association with the coverage of the Family Health Strategy after the implementation of the Master Plan for Primary Health Care in Minas Gerais, Brazil. METHODS This is an ecological study with 452 cities grouped according to population size, with data from 2004 to 2007 and 2010 to 2013. We used the Kolmogorov-Smirnov test to verify the distribution of the data in the groups. We used the Wilcoxon test for paired data or the paired Student's t-test to compare the rate of ambulatory care sensitive hospitalizations before and after the Master Plan for Primary Health Care. We used the simple linear regression test to analyze the association between variables. We performed statistical analyses using the Statistical Package for the Social Sciences, with a significance level of 5%. RESULTS The rate of ambulatory care sensitive hospitalizations decreased significantly after the Master Plan for Primary Health Care in the large and mid-sized groups (p < 0.05). There were positive correlations between coverage with Family Health Strategy and the rate of ambulatory care sensitive hospitalizations in the mid-sized and large groups (p < 0.05). CONCLUSIONS Actions were carried out to implement the Master Plan for Primary Health Care. However, more investments are needed to improve the effectiveness of the Primary Health Care, with permanent confrontation of complex issues that affect the quality of services, which can lead to a significant reduction of the rates of ambulatory care sensitive hospitalizations.

Abstract
Asthma is reported as one of the most common chronic diseases in childhood, impairing the quality of life of patients and their families and incurring high costs to the healthcare system and society. Despite the development of new drugs and the availability of international treatment guidelines, asthma is still poorly controlled, especially in Latin America. Original and review articles on asthma control or epidemiology with high levels of evidence have been selected for analysis among those published in PubMed referenced journals during the last 20 years, using the following keywords: "asthma control" combined with "Latin America", " epidemiology", "prevalence", "burden", "mortality", "treatment and unmet needs", "children", "adolescents", and "infants". There was a high prevalence and severity of asthma during the period analyzed, especially in children and adolescents. Wheezing in infants was a significant reason for seeking medical care in Latin American health centers. Moreover, the frequent use of quick-relief bronchodilators and oral corticosteroids by these patients indicates the lack of a policy for providing better care for asthmatic patients, as well as poor asthma control. Among adults, studies document poor treatment and control of the disease, as revealed by low adherence to routine anti-inflammatory medications and high rates of emergency care visits and hospitalization. In conclusion, although rare, studies on asthma control in Latin America repeatedly show that patients are inadequately controlled and frequently overestimate their degree of asthma control according to the criteria used by international asthma treatment guidelines. Additional education for doctors and patients is essential for adequate control of this illness, and therefore also for reduction of the individual and social burden of asthma.

Abstract
Abstract: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, and outpatient pulmonary rehabilitation (OPR) has shown positive results. The aim of this study was to investigate the effects of home or community-based pulmonary rehabilitation (HCPR) in individuals with COPD. This systematic review and meta-analysis of randomized clinical trials compared HCPR to controls and HCPR to OPR according to functional capacity, dyspnea, and quality of life in individuals with COPD. 3,172 citations were identified in databases, and 23 were included in this review. HCPR proved superior to controls based on functional capacity in the 6-Minute Walk Test and Incremental Shuttle Walk Test, and based on dyspnea and quality of life in the Saint George's Respiratory Questionnaire and the Chronic Respiratory Questionnaire. When HCPR and OPR were compared, there were no effect differences in functional capacity or quality of life. Improvement was greater in patients with more bronchial obstruction measured by FEV1. HCPR improves functional capacity and quality of life and decreases the sensation of dyspnea. Its benefits in functional capacity and quality of life are comparable to those obtained with OPR in individuals with COPD.

Abstract
OBJECTIVE To assess the changes in incidence, use of mechanical ventilation, length of stay (LOS), costs and mortality of children (0-15 years) and young adults (16-45 years) hospitalized for asthma exacerbations. METHODS We included patients hospitalized for asthma exacerbations in Spain from 2002 to 2010 (ICD9-CM codes 493.0x-493.9x). The data were collected from the National Hospital Discharge Database (entire population). We calculated the yearly age- and sex-specific incidence rates for each of the two groups. RESULTS We included a total of 12,038 pediatric patients and 2792 young adults hospitalized for asthma exacerbations. Overall crude incidence decreased from 20.5 to 18.7 admissions per 100.000 inhabitants in the pediatric group (p < 0.05), and from 4.12 to 3.68 admissions per 100.000 inhabitants among young adults, from 2002 to 2010 (p < 0.05). By contrast, we detected a significant increase in the use of non-invasive ventilation (NIV) in both groups. The average LOS decreased during the study period, from 3.71 (SD 2.28) to 3.16 (SD 2.11) days (p < 0.05) among pediatric patients and there were not changes among young adults. During the study period, the mean cost per patient decreased from 1558.53 (SD 443.63) to 1378.41 (SD 472.71) euros in the pediatric group (p < 0.05), while increased from 2183.44 (SD 783.15) to 2564.32 (SD 1933.98) euros among young adults (p < 0.05). CONCLUSION Our results suggest a decrease in the incidence of hospital admissions for asthma exacerbations with concomitant increase in use of NIV in asthmatic patients, both pediatric and young adults patients. Although LOS and mean cost have decreased among pediatric patients, they have not changed and increased, respectively, among young adults. A better management of the disease at primary care services may explain the improvement in the incidence and outcomes.

Abstract
OBJECTIVE We aim to analyze changes in incidence, comorbidity profile, length of hospital stay (LOHS), costs and in-hospital mortality (IHM) of patients hospitalized for acute exacerbations of chronic obstructive pulmonary disease (AE-COPD) over a 5-year study period in Spain. METHODS We selected all hospital admissions for AE-COPD between 2006 and 2010 from the National Hospital Discharge Database covering the entire population of Spain. RESULTS We identified a total of 215,835 patients. Overall crude incidence had decreased from 2.9 to 2.4 exacerbations of COPD per 10,000 inhabitants from 2006 to 2010 (p < 0.001). In 2006, 17.9% of patients had a Charlson Index >2 and in 2010, the prevalence had increased to 25.0% (p < 0.001). Regarding to treatment, we detected a significant increase in the use of non-invasive ventilation from 2.1% in 2006 to 5.3% in 2010 (p < 0.001). The median LOHS was 7 days in 2006 and it remained stable until 2010. During the period studied, the mean cost per patient increased from 3747 to 4129 Euros. Multivariate analysis showed that incidence of hospitalizations for AE-COPD and IHM had significantly decreased from 2006 to 2010. CONCLUSIONS The current study provides data indicating a decrease in incidence of hospital admissions for AE-COPD in Spain from 2006 to 2010 with concomitant reduction in IHM, despite increasing comorbidity during this period, with no variations in LOHS. The mean cost per patient has risen significantly.
