Abstract:
Objective: To study the demographic, rates and types of chronic respiratory conditions in Indigenous and non-Indigenous patients in regional and remote communities of Northern Territory Top End, who were referred to the specialist respiratory outreach service. Design: A retrospective, observational study over a 2 years period. Setting: Remote community health clinics within the Northern Territory Top End visited by the specialist respiratory outreach team. Participants: Only patients referred to respiratory specialist outreach team were included. There were 444 participants, with 210 males and 234 females. In total, 79.3% were Indigenous. Main outcome measures: The rates of chronic respiratory disease diagnoses and smoking status within the different communities and health district regions. Results: Chronic obstructive pulmonary disease (COPD) was the most common primary respiratory condition in our cohort of patients (50.5%) followed by sleep apnoea in (14.2%), bronchiectasis in (11.6%), asthma (11%), interstitial lung disease (2.5%), nodule/cancer (1.8%) sarcoidosis (0.2%) and others (9.2%). COPD, smoking status and bronchiectasis was more frequently noted among the Indigenous patients compared to non-Indigenous patients (56.3% versus 28.3%, P < 0.001), (52.6% versus 25.0%, P < 0.001), and (12.5% versus 3.3%, P = 0.01) respectively. Obstructive sleep apnoea was more commonly diagnosed in non-Indigenous patients. Conclusion: Indigenous patients of the remote and rural communities of the Top End have significantly higher rates of smoking and COPD compared to non-Indigenous patients. Bronchiectasis is also more common among Indigenous patients. Further efforts are warranted to develop strategies to address the disparity and optimise the respiratory outreach service to this population.
