Chronic Obstructive Pulmonary Disease (COPD) is a major cause of chronic morbidity and mortality throughout the world. Many people suffer from this disease for many years and die prematurely from it or its complications. COPD is a preventable and treatable pulmonary disease. In early stage, diagnosis of COPD is difficult because sign & symptoms are minimum. Only history of mild dyspnea, cough and/or sputum production or prolong smoking, exposure to occupational dusts or biomass fuels are present without any sign. Spirometry is the tool to diagnose COPD. If we can diagnose COPD in early stage then it is treatable and can prevent progression of the disease. Spirometry is a simple tool to diagnose COPD at any health care level. So this study was done to diagnose COPD in early stage among smokers. This study was carried out in Department of Medicine (Indoor & outdoor) of Rajshahi Medical College Hospital from March, 2010 to February, 2011. 255 smoker having exposure to >10 pack year smoking fulfilling inclusion and exclusion criteria were included and 300 apparently healthy non-smoker also were included as control. Both male & female were included with age of the study population were from 30 years to 70 years. All of that study population was free from diseases which alter spirometric measurement. This exclusion was done by history, thorough clinical examination and relevant investigations. Among smokers, clinically 9(4.03%) were diagnosed to have COPD only and the spirometry also diagnosed these 9 smokers and other 32 smokers more to have COPD and thus diagnose 41(18.38%) smokers to have COPD. The difference between clinical and spirometric diagnosis of COPD is statistically highly significant. The test done was Fisher’s Exact Test, where p value is 0.000. So, spirometry is considered as a simple valuable instrument to diagnose COPD in early stage among smokers. TAJ 2019; 32(1): 33-38

Previous studies of associations of forced expiratory lung volume in one second (FEV1) with peak oxygen uptake (VO2peak) in chronic obstructive pulmonary disease (COPD) have not taken sex, age and height related variance of dynamic lung volumes into account. Nor have such demographic spread of spirometric measures been considered in studies comparing VO2peak between COPD phenotypes characterized by degree of emphysema. We aimed to assess the association of FEV1Z-score with VO2peak in COPD (n = 186) and investigate whether this association differs between emphysema (E-COPD) and non-emphysema (NE-COPD) phenotypes. Corresponding assessments using standardized percent predicted FEV1 (ppFEV1) were performed for comparison. Additionally, phenotype related differences in VO2peak were compared using FEV1Z-score and ppFEV1 as alternative expressions of FEV1. E-COPD and NE-COPD were defined by transfer factor of the lung for carbon monoxide below and above lower limits of normal (LLN), respectively. The associations were assessed in linear regression models. One unit reduction in FEV1Z-score was associated with 1.9 (95% CI 1.4, 2.5) ml/kg/min lower VO2peak. In stratified analyses, corresponding estimates were 2.2 (95% CI 1.4, 2.9) and 1.2 (95% CI 0.2, 2.2) ml/kg/min lower VO2peak in E-COPD and NE-COPD, respectively. The association did not differ statistically by COPD phenotype (p-value for interaction = 0.153). Similar estimates were obtained in analyses using standardized ppFEV1. Compared to NE-COPD, VO2peak was 2.2 (95% CI 0.8, 3.6) and 2.1 (95% CI 0.8, 3.5) ml/kg/min lower in E-COPD when adjusted for FEV1Z-score and ppFEV1, respectively. In COPD, FEV1Z-score is positively associated with VO2peak. This association was stronger in E-COPD but did not differ statistically by phenotype. Both the association of FEV1 with VO2peak and the difference in VO2peak comparing COPD phenotypes seems independent of sex, age and height related variance in FEV1. Mechanisms leading to reduction in FEV1 may contribute to lower VO2peak in E-COPD.

Abstract Background Chronic obstructive pulmonary disease (COPD) and lung cancer are associated diseases. COPD is underdiagnosed and thus undertreated, but there is limited data on COPD diagnosis in the setting of lung cancer. We assessed the diagnosis of COPD with lung cancer in a large public healthcare system. Methods Anonymous administrative data was acquired from ICES, which links demographics, hospital records, physician billing, and cancer registry data in Ontario, Canada. Individuals age 35 or older with COPD were identified through a validated, ICES-derived cohort and spirometry use was derived from physician billings. Statistical comparisons were made using Wilcoxon rank sum, Cochran-Armitage, and chi-square tests. Results From 2002 to 2014, 756,786 individuals were diagnosed with COPD, with a 2014 prevalence of 9.3%. Of these, 51.9% never underwent spirometry. During the same period, 105,304 individuals were diagnosed with lung cancer, among whom COPD was previously diagnosed in 34.9%. Having COPD prior to lung cancer was associated with lower income, a rural dwelling, a lower Charlson morbidity score, and less frequent stage IV disease (48 vs 54%, p < 0.001). Spirometry was more commonly undertaken in early stage disease (90.6% in stage I-II vs. 54.4% in stage III-IV). Conclusion Over a third of individuals with lung cancer had a prior diagnosis of COPD. Among individuals with advanced lung cancer, greater use of spirometry and diagnosis of COPD may help to mitigate respiratory symptoms.

Objective: To investigate the effects of pharmacy counseling on clinical and economic outcomes in acute exacerbations of chronic obstructive pulmonary disease (AECOPD) patients.Material and Methods: The outcomes consisted of 28-day hospital readmissions related to AECOPD, direct costs, medication adherence calculated by proportion of days covered (PDC), and health-related quality of life (HRQoL) measured by chronic obstructive pulmonary disease assessment test (CAT). The data derived from the intervention group, for which pharmacy counseling was provided, was compared with that obtained from the control group provided with usual pharmaceutical care. The study also drew comparisons between the PDC and CAT scores of pre- and postintervention periods.Results: Forty-four patients (23 intervention and 21 control) were included in the analysis. There were no significant differences in the readmission rate (13% vs 19%, p-value>0.050), nor the number of readmitted patients (3 vs 3, p-value >0.050). A decrease in direct costs did not reach statistical significance (p-value>0.050). In addition, no difference between the PDC scores was found (96.67 vs 100.00, p-value>0.050). Intervention patients obtained significantly lower CAT scores than the control patients did (9 vs 19, p-value<0.050). Compared with the pre-intervention period, PDC scores were identical; however, CAT scores measured during the post-intervention period were significantly different.Conclusion: Pharmacy counseling for AECOPD patients could enhance HRQoL. Drug therapy and pulmonary rehabilitation may cause such improvement. Further work, which has adequate participants, is required to detect a significant difference in readmissions between the two groups.

Abstract Aims The aim of this study was to clarify the effect of β-blockers (BBs) on respiratory function and survival in patients with chronic obstructive pulmonary disease with cardiovascular disease (CVD), as well as the difference between the effects of cardioselective and noncardioselective BBs. Methods and results We searched for relevant literature in four electronic databases, namely, PubMed, EMBASE, Cochrane Library, and Web of Science, and compared the differences in various survival indicators between patients with chronic obstructive pulmonary disease taking BBs and those not taking BBs. Forty-nine studies were included, with a total sample size of 670 594. Among these, 12 studies were randomized controlled trials (RCTs; seven crossover and five parallel RCTs) and 37 studies were observational (including four post hoc analyses of data from RCTs). The hazard ratios (HRs) of chronic obstructive pulmonary disease exacerbation between patients with chronic obstructive pulmonary disease who were not treated with BBs and those who were treated with BBs, cardioselective BBs, and noncardioselective BBs were 0.77 [95% confidence interval (CI) 0.67, 0.89], 0.72 [95% CI 0.56, 0.94], and 0.98 [95% CI 0.71, 1.34, respectively] (HRs &lt;1 indicate favouring BB therapy). The HRs of all-cause mortality between patients with chronic obstructive pulmonary disease who were not treated with BBs and those who were treated with BBs, cardioselective BBs, and noncardioselective BBs were 0.70 [95% CI 0.59, 0.83], 0.60 [95% CI 0.48, 0.76], and 0.74 [95% CI 0.60, 0.90], respectively (HRs &lt;1 indicate favouring BB therapy). Patients with Chronic obstructive pulmonary disease treated with cardioselective BBs showed no difference in ventilation effect after the use of an agonist, in comparison with placebo. The difference in mean change in forced expiratory volume in 1 s was 0.06 [95% CI −0.02, 0.14]. Conclusion The use of BBs in patients with chronic obstructive pulmonary disease is not only safe but also reduces their all-cause and in-hospital mortality. Cardioselective BBs may even reduce chronic obstructive pulmonary disease exacerbations. In addition, cardioselective BBs do not affect the action of bronchodilators. Importantly, BBs reduce the heart rate acceleration caused by bronchodilators. BBs should be prescribed freely when indicated in patients with chronic obstructive pulmonary disease and heart disease.

We developed a chronic obstructive pulmonary disease (COPD) patient-reported experience measure (PREM-C9). 174 patients with COPD (86 [49%] with a confirmed diagnosis and 88 [51%] with a self-reported diagnosis of COPD) completed a 38-item list, COPD Assessment Test (CAT) and Hospital Anxiety and Depression Scale (HADS). Hierarchical and Rasch analysis produced a 9-item list (PREM-C9). It demonstrated fit to the Rasch model (χ² p=0.33) and correlated moderately with CAT (r=0.42), HAD-anxiety (r=0.30) and HAD-depression (r=0.41) (p<0.05). A substudy confirmed its ability to detect change prepulmonary and postpulmonary rehabilitation. The PREM-C9 is a simple, valid measure of experience of patients living with COPD, validated in this study population with mild to very severe disease; it may be a useful measure in research and clinical audits.

To identify patients hospitalized for an acute exacerbation of chronic obstructive pulmonary disease (COPD) who have a poor prognosis and might benefit from proactive palliative care, a set of indicators had been developed from the literature. A patient is considered eligible for proactive palliative care when meeting ≥2 criteria of the proposed set of 11 indicators. In order to develop a doctor-friendly and patient-convenient tool, our primary objective was to examine whether these indicators are documented consistently in the medical records. Besides, percentage of patients with a poor prognosis and prognostic value were explored. We conducted a retrospective medical record review of 33 patients. Five indicators; non-invasive ventilation (NIV), comorbidity, body mass index (BMI), previous admissions for acute exacerbation COPD and age were always documented. Three indicators; hypoxaemia and/or hypercapnia, professional home care and actual forced expiratory volume1% (FEV1%) were documented in more than half of the records, whereas the clinical COPD questionnaire (CCQ), medical research council dyspnoea (MRC dyspnoea) and the surprise question were never registered. Besides, 78.8% of the patients met ≥2 criteria and there was a significant association between meeting ≥2 criteria and mortality within 1 year (one-sided Fisher’s exact test, p = 0.04). The set of indicators for proactive palliative care in patients with COPD appeared to be user-friendly and feasible.
