Insights
A new cardiovascular risk index identified individuals at high risk, correlating with increased hospital admissions and clinic visits. This tool aids in predicting healthcare utilization and guiding interventions for better cardiovascular event prevention.
Area of Science:
- Cardiology
- Public Health
- Health Services Research
Background:
- Cardiovascular diseases remain a leading cause of morbidity and mortality.
- Accurate risk stratification is crucial for targeted preventive strategies and resource allocation.
- Existing risk assessment tools may not fully capture the spectrum of healthcare utilization associated with cardiovascular risk.
Purpose of the Study:
- To develop and validate a novel index for measuring cardiovascular risk in a large adult population.
- To assess the association between different levels of cardiovascular risk and healthcare utilization patterns.
- To explore the utility of the index for estimating healthcare costs and identifying populations for intervention.
Main Methods:
- Construction of a composite index to categorize individuals into high, average, or low cardiovascular risk groups.
- Analysis of healthcare utilization data, including hospital admissions, hospital days, and clinic visits, for 1,991 adults.
- Multivariate regression analyses controlling for demographic factors such as gender and age.
Main Results:
- Individuals classified with high cardiovascular risk exhibited significantly higher odds of hospital admissions (OR = 3.9) and total hospital days (OR = 4.0) compared to those with low risk.
- High cardiovascular risk was strongly associated with increased primary care clinic visits (OR = 7.3) and subspecialty clinic visits (OR = 2.3).
- Statistical significance was maintained across all measured utilization outcomes (p < 0.0001 for admissions and primary care visits).
Conclusions:
- The developed cardiovascular risk index effectively identifies individuals with elevated risk profiles.
- The index demonstrates a strong positive association with increased healthcare utilization, suggesting potential for cost and resource management.
- This tool can facilitate the identification of patient groups requiring targeted interventions and enable population-based evaluation of preventive strategies.
Abstract:
The investigators constructed an index measure of cardiovascular risk and scored 1.991 adults as having high, average, or low cardiovascular risk. High cardiovascular risk was positively associated with hospital admissions (odds ratio [OR] = 3.9, p < 0.0001), total hospital days (OR = 4.0, p < 0.001), primary care clinic visits (OR = 7.3, p < 0.0001), and subspecialty clinic visits (OR = 2.3, p = 0.0003), compared to low cardiovascular risk, after controlling in multivariate analyses for gender and age. The index can provide estimates of utilization, costs, and potential preventability of adverse cardiovascular events, can be used to identify groups of patients in need of various systematic interventions, and can provide population-based ways to evaluate the results of interventions.
