Surgonomics: the cost of gastrointestinal hemorrhage, the identifier concept
Insights
Hospital charges vary widely within Diagnostic Related Groups (DRGs). Transfusions significantly increase costs for gastrointestinal hemorrhage patients, suggesting identifiers can refine DRG cost analysis for better financial management.
Area of Science:
- Health Economics
- Hospital Financial Management
- Medical Billing
Background:
- The Tax Equity and Fiscal Responsibility Act mandates fixed payments for Medicare patients based on Diagnostic Related Groups (DRGs).
- Understanding cost variations within DRGs is crucial for effective hospital financial strategies and cost containment.
- Previous analyses have not fully explored patient-level cost drivers within specific DRGs.
Purpose of the Study:
- To conduct an in-depth financial analysis of a specific DRG (DRG 175) for gastrointestinal hemorrhage patients.
- To identify potential cost-saving strategies through detailed financial examination.
- To test the hypothesis that patient identifiers, such as transfusion status, can effectively subgroup patients within a DRG to reveal cost differences.
Main Methods:
- Analysis of hospital charges for 46 gastrointestinal hemorrhage patients under 70 without complications or surgery (DRG 175) at Long Island Jewish-Hillside Medical Center in 1983.
- Categorization of patients based on transfusion requirements (requiring transfusion vs. not requiring transfusion).
- Comparison of total charges, hematology charges, and blood charges between the two patient subgroups.
Main Results:
- Significant variance in total hospital charges ($3891 +/- 2128 per patient) was observed within DRG 175.
- Patients requiring transfusions incurred substantially higher total charges ($4707 +/- 2292) compared to those not requiring transfusions ($2765 +/- 1300).
- Transfused patients had 170% greater total charges, 165% higher hematology charges, and 526% greater blood charges.
Conclusions:
- Wide cost variations exist within individual Diagnostic Related Groups.
- Patient identifiers, like transfusion status, can effectively stratify patients within a DRG to highlight significant differences in resource consumption.
- Implementing DRG-specific cost containment strategies may be enhanced by considering clinical identifiers that predict resource intensity.
Abstract:
The Tax Equity and Fiscal Responsibility Act will pay hospitals a set price for Medicare patients by one of 467 Diagnostic Related Groups (DRGs). The purpose of this study was to examine one DRG and perform indepth financial analysis in order to develop strategies for cost containment. In addition, we tested the hypothesis that an entity called an identifier (here, the presence or absence of transfusions) could be used to group patients within a specific DRG and demonstrate differences in costs. All patients (n = 46) with gastrointestinal hemorrhage under 70 years old without complications and not requiring surgery (DRG 175) treated at the Long Island Jewish-Hillside Medical Center during 1983 had their hospital charges examined. Total charges (hospital charges exclusive of physician fees) were $3891 +/- 2128 (mean +/- SEM)/patient. Patients requiring transfusion (n = 26) had total charges of $4707 +/- 2292, whereas those not requiring transfusion (n = 20) had total charges of $2765 +/- $1300. Findings in this study are: 1) within a given DRG there is a wide variance of hospital charges, 2) identifiers (in this case transfusion) may be used to clinically aggregate patients with similar resource consumption within a DRG, 3) patients receiving transfusion had 170% greater total charges, 165% greater hematology charges, and 526% greater total blood charges than those not receiving transfusion.
