The RRP decreases the duration of antibiotic use, the length of inpatient stay, and the time in isolation.
Background: The Aboriginal population of Australia has a higher burden of chronic health conditions than non-Aboriginal Australians. However, there is a paucity of data on clinical and demographic characteristics of chronic obstructive pulmonary disease (COPD) in this population. Method: In this retrospective study we evaluated the clinical, demographic and environmental influences in adult Aboriginal patients with COPD living in the regional and remote communities of the Northern Territory of Australia. Results: There were 380 patients (49%) with a diagnosis of COPD of the 767 patients referred to specialist respiratory outreach clinics. The mean age was 57 years (56% were female) and mean±SD BMI was 24.30±7.01 kg/m 2. Smoking history was noted in 93% of the study cohort. The most common respiratory symptom was shortness of breath in 62%, and inhaled medications (salbutamol, tiotropium, salmeterol/fluticasone) were used by 79%, 44% and 58% of patients, respectively. Spirometry showed obstructive impairment (FEV 1 / FVC <0.7) in 79% (0.56±0.17), with mean FEV 1 42% of predicted, and a bronchodilator response was present in 28.6%. Comorbid bronchiectasis was diagnosed in 49.8% along with COPD. The relationship between COPD and community demography showed a higher proportion of smokers and those with underlying bronchiectasis to have lower FEV 1 /FVC ratios. Communities with a higher proportion of asthma were younger and had higher smoking rates. Mortality increased with increasing number of exacerbations and hospital admissions. Conclusion: The Aboriginal population with COPD has a higher prevalence of smoking, moderate to severe airflow obstruction on spirometry and frequently co-diagnosed bronchiectasis with increased severity of ventilatory impairment.
Background: Chronic respiratory disorders are highly prevalent in Aboriginal Australian population, including chronic obstructive pulmonary disease (COPD) and bronchiectasis. However, there is paucity of information in the literature among Aboriginal patients with underlying COPD with and without bronchiectasis. Aims: In this retrospective study we evaluated the demographic and clinical characteristics of adult Aboriginal Australian patients with a clinical diagnosis of COPD with and without bronchiectasis from the remote communities of the Northern Territory of Australia. Methods: Clinical records were reviewed to extract information on demographics, respiratory and medical comorbid conditions, COPD directed treatment, hospital admission frequency and exacerbations. Chest radiology were reviewed to evaluate the presence or absence of bronchiectasis. Spirometry results, sputum culture and cardiac investigations were also recorded. Results: Of the 767 patients assessed in the remote community respiratory outreach clinics 380 (49%) patients had a clinical diagnosis of COPD. Chest X-ray and computed tomography scan were available to evaluate the presence of bronchiectasis in 258 patients. Of the 258/380 patients, 176/258 (68.2%) were diagnosed to have COPD alone and 82/258 (31.8%) had bronchiectasis along with COPD. The mean age was 56 and 59 years among patients with and without bronchiectasis, respectively, and 57% were males with bronchiectasis. Patients with bronchiectasis had lower body mass index (22 vs 24 kg/m 2), frequent hospital admissions (2.0 vs 1.5/year) and productive cough (32.1% vs 28.9%). Spirometry showed 77% had forced expiratory volume in 1 s (FEV 1)/forced vital capacity ratio <0.7. In 81% and 75% of patients with and without bronchiectasis the FEV 1 /forced vital capacity ratio was <0.7 and the mean FEV 1 was 39% and 43% respectively. Conclusions: About 32% of Aboriginal Australians had co-existent bronchiectasis with COPD. Lower body mass index, productive cough, frequent hospital admission and marginally more severe reduction in lung function were noted among patients with COPD and bronchiectasis compared to those with COPD in isolation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
