Insights
Cardiovascular disease (CVD) significantly increases healthcare resource use and costs for diabetic patients. Proactive CVD prevention in diabetes management is crucial for healthcare systems.
Area of Science:
- Medical Economics
- Public Health
- Cardiology
Background:
- Cardiovascular disease (CVD) is a major comorbidity in patients with diabetes.
- Diabetic patients with CVD face increased healthcare demands.
Purpose of the Study:
- To quantify the incremental healthcare resource utilization and expenditures (HRUE) in diabetic patients with CVD comorbidity.
- To assess the economic impact of CVD in the diabetic population.
Main Methods:
- A cross-sectional study analyzed 2014 data from the Iran Health Insurance Organization.
- Compared HRUE between diabetic patients with and without CVD from 2014-2016.
- Utilized generalized regression, negative binomial regression, and gamma distribution models.
Main Results:
- Diabetic patients with CVD showed significantly higher utilization for physician services, prescription drugs, lab tests, and medical imaging.
- Incremental costs for CVD comorbidity in diabetic patients were substantial across all healthcare services.
- The study identified a 22-58% increase in healthcare costs associated with CVD in diabetic individuals.
Conclusions:
- CVD comorbidity significantly elevates healthcare resource utilization and expenditures in diabetic patients.
- Findings underscore the need for healthcare decision-makers to prioritize CVD prevention strategies in diabetes care.
- Proactive CVD management can lead to significant healthcare cost savings in the diabetic population.
Background:
Cardiovascular disease (CVD) is the most prevalent comorbid condition among patients with diabetes. The objective of this study is to determine the incremental healthcare resource utilization and expenditures (HRUE) associated with CVD comorbidity in diabetic patients.
Methods:
In a cross-sectional study, patients receiving antidiabetic drugs were identified using the 2014 database of the Iran Health Insurance Organization of East Azerbaijan province (Iran). The frequency of HRUE was the main outcome. Outcome measures were compared between diabetic patients with and without CVD comorbidity during 2014-2016. The generalized regression model was used to adjust for cofounders because of a highly skewed distribution of data. Negative binomial regression and gamma distribution model were applied for the count and expenditure data, respectively.
Results:
A total of 34,716 diabetic patients were identified, of which 21,659 (63%) had CVD comorbidity. The incremental healthcare resource utilization associated with CVD compared to non-CVD diabetic patients for physician services, prescription drugs, laboratory tests, and medical imaging was 5.9±0.34 (28% increase), 46±1.9 (46%), 12.9±0.66 (27%), and 0.16±0.40 (7%), respectively (all P<0.001). Similarly, extra health care costs associated with CVD comorbidity for physician services, prescription drugs, laboratory tests, and medical imaging were 10.6±0.67 million IRR (294.4±18.6 USD) (50% increase), 1.44±0.06 million IRR (40±1.6 USD) (32%), 8.36±0.57 million IRR (232.2±15.8 USD) (58%), 0.51±0.02 million IRR (14.1±0.5 USD) (24%), and 0.29±0.02 million IRR (8±0.5 USD) (22%), respectively (all P<0.001).
Conclusion:
CVD comorbidity substantially increases HRUE in patients with diabetes. Our findings draw the attention of healthcare decision-makers to proactively prevent CVD comorbidity in diabetic patients.
