Insights
Respiratory diseases, particularly viral pneumonia, were the main reason for acute hospitalizations in Australian adults with diabetes and COVID-19. Post-COVID hospitalization reasons for these patients mirrored pre-pandemic trends.
Area of Science:
- Public Health
- Infectious Diseases
- Endocrinology
Background:
- Diabetes mellitus (type 1 and type 2) is a significant risk factor for severe COVID-19 outcomes.
- Understanding hospitalization drivers in diabetic populations during the COVID-19 pandemic is crucial for resource allocation and patient management.
Purpose of the Study:
- To investigate the primary causes of hospitalization among Australian individuals with diabetes (type 1 and type 2) following a COVID-19 diagnosis.
- To compare hospitalization reasons in diabetic COVID-19 patients with non-diabetic COVID-19 patients and pre-pandemic admission data.
Main Methods:
- Analysis of COVID-19 cases and linked hospitalization data in Victoria, Australia.
- Assessment of acute (0-30 days) and post-acute (31-365 days) hospitalizations.
- Comparison between diabetic and non-diabetic COVID-19 patients, and pre-pandemic controls.
Main Results:
- 13,302 diabetic Australians were hospitalized within a year of COVID-19 diagnosis.
- Respiratory diseases caused 40% of acute hospital admissions in diabetic patients.
- Viral pneumonia was the leading cause of acute hospitalization, occurring more frequently in diabetic patients (APR 1.87).
- Post-acute hospitalization patterns for diabetic patients were similar to those observed before the pandemic.
Conclusions:
- Respiratory conditions are the predominant cause of acute hospitalizations for diabetic individuals with COVID-19.
- Post-acute hospitalization reasons in this cohort align with established patterns for diabetes management.
- Emphasizes the need for robust community-based management of diabetes during the ongoing COVID-19 pandemic.
Objective:
Our aim in this study was to determine the reasons for hospitalization in Australian people with diabetes who contract COVID-19.
Methods:
All COVID-19 cases reported to the Victorian Department of Health and linked hospitalization data were assessed. We determined reasons for acute (0 to 30 days) and postacute (31 to 365 days) hospitalization among those with type 1 or type 2 diabetes and COVID-19, compared to those with COVID-19 and no diabetes, and to admissions before the COVID-19 pandemic.
Results:
A total of 13,302 Australians with type 1 or type 2 diabetes were hospitalized in the state of Victoria in the 12 months after COVID-19 diagnosis. Respiratory diseases accounted for 40% of acute admissions among those with diabetes. Viral pneumonia was the leading cause of acute hospitalization among those with diabetes and constituted a larger proportion of admissions in those with compared to those without diabetes (adjusted prevalence ratio 1.87, 95% confidence interval 1.76 to 1.99). The distribution of postacute hospitalizations among those with diabetes aligned with that of people with diabetes before the COVID-19 pandemic.
Conclusions:
Respiratory diseases are the leading cause of acute hospitalization in those with type 1 or type 2 diabetes and COVID-19. The reasons for postacute hospitalization resemble those in people with diabetes and no COVID-19. We reinforce the importance of community management of people with diabetes in the ongoing pandemic.
