An evaluation of potential prognostic indicators in cardiac patients
1LDS Hospital, Salt Lake City, UT.
Insights
Predicting specialized cardiac care needs is challenging. While a model showed promise for low and high-risk patients, it struggled with intermediate cases, impacting medical cost predictions.
Area of Science:
- Cardiology
- Health Services Research
- Health Economics
Background:
- Cardiovascular disease (CVD) is a leading cause of death and healthcare expenditure.
- Specialized care centers are utilized for managing complex cardiac conditions.
- Predicting the need for specialized care and associated costs is crucial for resource allocation.
Purpose of the Study:
- To evaluate historical, current event, and physiological factors in predicting specialized cardiac care utilization.
- To assess the ability of these factors to predict hospital costs.
- To develop a predictive model for patient stratification.
Main Methods:
- A retrospective study of 199 cardiac patients.
- Evaluation of 32 potential prognostic items.
- Development of a classification model based on identified predictors.
Main Results:
- Seven items were found to be prognostic for specialized care needs.
- The model demonstrated high sensitivity and specificity for patients without predictors and those with multiple predictors.
- The model's prognostic ability was limited for patients in intermediate risk categories (63% of cohort).
- Diagnostic-only and Medicare patients incurred financial deficits.
- Extended stays (>7 days) or surgery significantly impacted hospital profitability, especially for non-Medicare patients.
Conclusions:
- Accurate prediction of specialized cardiac care needs and associated costs remains challenging, particularly for intermediate-risk patients.
- Advance validation of transport necessity is difficult, with significant medical and financial consequences.
- Current predictive models may not be sufficient for comprehensive patient management and cost control in cardiovascular care.
Abstract:
Cardiovascular disease results in more deaths and higher medical costs than any other medical problem. Cardiac patients may be transported to centers for specialized care. We evaluated historical, current event, and physiologic items (n = 32) for ability to predict use of specialized care and hospital costs. For 199 patients studied, seven items were prognostic. A model classifying patients by presence of predictors was developed. For the group without predictors and the group with multiple predictors, sensitivity and specificity were respectively very good. For 125 (63%) of the patients in middle categories, the model was not sufficiently sensitive to be prognostic. A scoring system for all cardiac patients could not be developed. Patients requiring only diagnostics were responsible for financial deficits, as were all Medicare patient groups. Patients staying longer than seven days, or having surgery, or both, were responsible for the largest deficits (if on Medicare) and the highest profits (if not on Medicare). Advance validation of the need to transport is difficult, with far-reaching medical and financial implications.
