1. What Are Adjusted Admissions?

Adjusted Admissions represent hospital admissions normalized for complexity using the Case Mix Index. This metric provides a more accurate comparison of hospital workload by accounting for the severity and complexity of patient cases.

2. How Does the Calculator Work?

The calculator uses the Adjusted Admissions formula:

Where:

• \( \text{Raw Admissions} \) — Total number of hospital admissions (count)
• \( \text{Case Mix Index} \) — Measure of patient complexity and resource utilization (factor)
• \( \text{Adjusted Admissions} \) — Complexity-normalized admission count (count)

Explanation: The formula adjusts raw admission counts to reflect the actual workload and resource demands by multiplying by the Case Mix Index, which typically ranges from 1.0 to 2.5 or higher depending on hospital specialization.

3. Importance of Adjusted Admissions

Details: Adjusted Admissions are crucial for fair comparisons between hospitals, resource allocation, staffing decisions, and performance benchmarking. They help account for differences in patient acuity and complexity across different healthcare facilities.

4. Using the Calculator

Tips: Enter the total number of raw admissions and the Case Mix Index. Both values must be positive numbers. The Case Mix Index is typically calculated based on DRG weights and patient diagnosis data.

5. Frequently Asked Questions (FAQ)

Q1: What is Case Mix Index (CMI)?
A: CMI is a measure of the average relative diagnosis-related group (DRG) weight for a hospital's inpatient discharges during a given period. It reflects patient complexity and resource needs.

Q2: How is CMI calculated?
A: CMI is calculated by summing the DRG weights for all discharges and dividing by the total number of discharges. Higher CMI indicates more complex cases.

Q3: Why use adjusted admissions instead of raw counts?
A: Adjusted admissions provide a fairer comparison by accounting for differences in patient complexity, making it possible to compare hospitals with different patient populations and specialties.

Q4: What is a typical CMI range?
A: Community hospitals typically have CMIs around 1.0-1.5, while tertiary care and academic medical centers may have CMIs of 1.5-2.5 or higher due to more complex cases.

Q5: How often should adjusted admissions be calculated?
A: Adjusted admissions are typically calculated monthly, quarterly, and annually for reporting, benchmarking, and strategic planning purposes.
