Chronic Obstructive Pulmonary Disease (COPD) is a chronic inflammatory lung disease, which affects 2.2% of the NSW adult population [1]. Management of COPD is spread across the primary and acute care systems.
This fact sheet outlines factors that affect the use of acute health care services by people aged 45+ living with COPD in NSW.
The analysis used patient data from the Lumos data asset, which links data from general practices (GPs) with data from other NSW Health services. The analysis focuses on the 2019 calendar year to illustrate delivery and access behaviours seen prior to COVID-19 disruptions. The key findings are controlled for demographics, health status, and previous health service utilisation.
The aim of this work is to gain a better understanding about healthcare needs among people living with COPD to inform health services management and planning.
(from Lumos data >500 GP practices, ~5 million population)
In the 12 months prior to this analysis:
People with COPD with no smoking status recorded in their GP records, and daily smokers with COPD, were more likely to end up in ED or hospital compared to people with COPD who have never smoked. Ex-smokers were no more likely to attend ED or have an unplanned admission than a person with COPD who never smoked. There were no notable results found for irregular smokers.
People with COPD who had regular GP visits were less likely to end up in hospital than people with COPD who had no GP visits recorded in the past year.
Having 1 or more other comorbidities previously diagnosed in hospital significantly increased the likelihood of people with COPD ending up in hospital compared to people with COPD who had no additional comorbidities.
People living with COPD in regional or remote areas were more likely to present to the emergency department than those living in a major city. However, people with COPD living in major cities were more likely to have an unplanned hospitalisation than people with COPD living in regional or remote areas.
By bringing together data from participating GPs and state health data sets, Lumos makes it possible to understand the health care journeys of different cohorts of people living with COPD in NSW, and to optimise health service delivery accordingly.
The Lumos program links records from participating NSW general practices (GPs) to records held by NSW Health such as hospital admissions, emergency department and outpatient visits, and mortality.
This factsheet provides information about care received in acute and primary care by NSW people aged 45 years and over with a diagnosis of COPD that is available in the Lumos data asset.
528 general practices, representing approximately 21% of all NSW general practices, provided data to Lumos in October 2022
4,801,341 people were included in the Lumos cohort extracted in October 2022, representing approximately 59% of the NSW population at the time.
51,598 people were included in the analysis. These comprised those aged 45 years and over attending a Lumos participating GP with a COPD diagnosis recorded in their GP or hospital records on or prior to 31 December 2018. These patients' hospital and emergency department activities were analysed over a 1 year follow up period (1 January 2019 – 31 December 2019).
528 general practices, representing approximately 21% of all NSW general practices, provided data to Lumos in October 2022.
Multi-variable logistic regression modelling was used to determine potential protective and risk factors for propensity for emergency presentations and unplanned hospitalisations in a 1 year follow up period.
The analyses adjusted for; Demographics (IRSAD quintile, age, sex, CALD, marital status, remoteness), total number of chronic diseases previously diagnosed in hospital (0,1,2,3+ for the conditions arthritis, asthma, back pain, cancer, cardiovascular disease, chronic obstructive pulmonary disease, diabetes, chronic kidney disease, mental health conditions and osteoporosis) and previous health service utilisation (Number of GP visits in the prior year, prior history of COPD exacerbations, GP – type ED visit post discharge, Non GP- type ED visit post discharge).
