Insights
Patients with ischemic stroke (IS) and concordant comorbidities face higher readmission rates and healthcare costs. Managing these specific comorbidities is crucial for better patient outcomes and reduced healthcare expenditure.
Area of Science:
- Health Services Research
- Epidemiology
- Clinical Medicine
Background:
- Ischemic stroke (IS) comorbidities are a growing global health concern.
- Understanding the impact of comorbidities on IS patient outcomes is vital for healthcare management.
Purpose of the Study:
- To quantitatively assess how different types of comorbidity affect readmission and hospitalization costs in IS patients.
- To analyze the association between concordant and discordant comorbidities and IS patient outcomes.
Main Methods:
- Retrospective observational study using Chinese insurance claims data (2018-2022).
- Inclusion of 99,649 adult IS patients with one-year follow-up.
- Categorization of 18 comorbidities into concordant and discordant types.
- Application of multivariable logistic regression and generalized linear models.
Main Results:
- Nearly all IS patients (94.0%) had at least one comorbidity; 63.8% had only concordant comorbidity.
- The overall IS readmission rate was 26.7%, with mean annual hospitalization expenditure of 28,086.6 CNY.
- Concordant comorbidity-only group showed the highest readmission rates, annual hospitalization expenditure, and out-of-pocket expenditure (OOPE).
- Increased number of comorbidities correlated with higher readmission rates and expenditures.
Conclusions:
- Comorbidities significantly impact readmission rates and healthcare expenditures for IS patients.
- Concordant comorbidities are particularly associated with increased hospital readmission risk and health costs.
- Developing targeted care strategies for managing comorbidities, especially concordant ones, is essential for IS patient management.
Background:
The comorbidities of ischemic stroke (IS) are increasing worldwide. This study aimed to quantitatively assess the effect of different types of comorbidity on readmission and hospitalization expenditures of patients with IS.
Methods:
A retrospective observational study was conducted from the basic insurance claims database of a large city in China, between January 1, 2018, and May 31, 2022. We identified patients with IS aged 18 years and over, who experienced the first episode of IS and had one-year follow-up records. This study divided eighteen different comorbid conditions into two categories (concordant comorbidity and discordant comorbidity) and the IS patients were further categorized into four groups. Multivariable logistic regression models and generalized linear models with log-link and gamma distribution were to estimate the effect of different comorbidity groups on one-year readmission rates and annual hospitalization expenditures.
Results:
In total, 99,649 adult patients with IS were identified. Approximately 94.0 % of patients with IS had at least one comorbidity, and 63.8 % reported concordant comorbidity only. Patients with IS had a readmission rate of 26.7 %, and the mean of annual hospitalization expenditure and annual hospitalization out-of-pocket expenditure (OOPE) were 28086.6 Chinese Yuan (CNY) and 8267.3 CNY, respectively. After adjustment for covariates, the concordant comorbidity-only group had the highest readmission rate, annual hospitalization expenditure, and OOPE compared with the other groups, furthermore, these results increased as the number of comorbidity increased and had statistically significant positive associations.
Conclusions:
The readmission and annual hospitalization expenditures of patients with IS were associated with different comorbidities. Concordant comorbidity increased hospital readmission risk and health expenditures. To better manage the comorbidities of patients with IS, especially concordant comorbidities, it is necessary to establish a routine care strategy specifically for comorbid conditions.
