Insights
Avoidable hospitalizations before COVID-19 infection increased the risk of death from the disease. This highlights the need for continuous healthcare and preventive measures to reduce such hospitalizations and improve outcomes for coronavirus disease patients.
Area of Science:
- Public Health
- Epidemiology
- Healthcare Management
Background:
- Avoidable hospitalizations may increase vulnerability to severe outcomes from infectious diseases.
- Understanding the impact of prior healthcare experiences on COVID-19 mortality is crucial for public health strategies.
Purpose of the Study:
- To investigate the association between avoidable hospitalizations preceding COVID-19 infection and COVID-19-related mortality.
- To quantify the risk of death from coronavirus disease associated with prior avoidable hospitalizations.
Main Methods:
- Utilized the National Health Insurance Service-COVID-19 (NHIS-COVID-19) dataset from South Korea.
- Employed logistic regression and double robust estimation (DRE) to analyze the relationship between avoidable hospitalization and COVID-19 mortality.
Main Results:
- Logistic regression indicated a higher odds ratio (OR) for COVID-19 death in patients with prior avoidable hospitalizations.
- DRE confirmed a significantly higher OR for COVID-19 mortality among those with avoidable hospitalizations, except for individuals aged 69 years or younger.
Conclusions:
- Avoidable hospitalizations represent a significant risk factor for increased mortality in patients with COVID-19.
- Strengthening continuous healthcare, preventive medicine, and public health management is vital to mitigate avoidable hospitalizations and reduce COVID-19-related deaths.
Abstract:
Objectives: This study aimed to determine the effect of the presence or absence of avoidable hospitalization before acquiring coronavirus disease (COVID-19) on COVID-19-related deaths. Methods: This study used the total NHIS-COVID-19 dataset comprising domestic COVID-19 patients, provided by the National Health Insurance Service (NHIS) in South Korea. We conducted logistic regression and double robust estimation (DRE) to confirm the effect of avoidable hospitalization on COVID-19-related deaths. Results: Logistic regression analysis confirmed that the odds ratio (OR) of death due to COVID-19 was high in the group that experienced avoidable hospitalization. DRE analysis showed a higher OR of death due to COVID-19 in the group that experienced avoidable hospitalization compared to the group that did not experience avoidable hospitalization, except in the subgroup aged ≤69 years. Conclusion: The effect of avoidable hospitalization on COVID-19-related deaths was confirmed. Therefore, continued health care, preventive medicine, and public health management are essential for reducing avoidable hospitalizations despite the COVID-19 pandemic. Clinicians need to be informed about the importance of continuous disease management.
