Supplement Twelve
The Use of Case-Mix in Assessing Efficiency
![Page 3: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/3.jpg)
Comparing Hospital Charges• Hospital charges are often used as a
surrogate for efficiency in comparing hospitals
• Patients assume that hospitals with lower cost are more efficient
• There is an attempt by some groups to publish price information in an effort to make hospitals more price competitive
![Page 4: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/4.jpg)
The question is, what do you compare?• Some hospitals see more complex
cases than others. It is not fair to compare the average room rate, for example, of a primary care hospital with a tertiary care hospital.

The question is, what do you compare?• One way to adjust for the
difference in the difficulty of cases seen is to use a case-mix index.
![Page 6: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/6.jpg)
Definition
•Case-mix refers to the acuity or severity of illness of the average patient seen in a particular hospital.–A hospital with a case-mix of 1.50 sees patients who on the average consume 1.50 more resources because of the severity of their illnesses.
![Page 7: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/7.jpg)
Case-mix Indexes
• Medicare has assigned a case-mix index to each of its DRGs.
• These are published by Medicare.• These can be used to calculate the
case-mix index for a specific hospital as shown on the next slide.
![Page 8: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/8.jpg)
ExampleThe Controller of Morgan Community Hospital has provided you with the following information on all of the cases seen at the hospital last year. Case-mix indexes were taken from Medicare.
DRG Case-mix Index
[B]
Cases Seen
[C]
DRG A 1.211 1,200
DRG B .8567 1,000
DRG C 1.809 900
DRG D 1.111 1,100
DRG E .7645 250
DRG F .6543 3,200
Total 7,650
![Page 9: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/9.jpg)
ExampleMultiply the individual case-mix indexes by the number of cases seen.DRG Case-mix Index
[B]
Cases Seen
[C]
[B] x [C] =
[D]
DRG 1 1.211 1,200 1,453.20
DRG 2 .8567 1,000 856.70
DRG 3 1.809 900 1,628.10
DRG 4 1.111 1,100 1,222.10
DRG 5 .7645 250 191.125
DRG 6 .6543 3,200 2,093.76
Total 7,650 9,165.11
Now divide Column D by Column C (9,165.11/7,650) = 1.20 (the hospital’s case-mix index).

ExampleThis data can then be used to calculate the average case-mix adjusted charge as shown below:

[B] x [C] =

DRG 1 1,200 $3,245 3,894,000
DRG 2 1,000 2,596 2,596,000
DRG 3 900 4,900 4,410,000
DRG 4 1,100 3,090 3,399,000
DRG 5 250 2,765 691,250
DRG 6 3,200 2,200 7,040,000
Total 7,650 $22,030,250
$22,030,250/7,650 = $2,879 average charge
$2,879/1.20 = $2,399.16 case mix adjusted charge
![Page 11: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/11.jpg)
How do we use this information?Shown below is data on two competing community hospitals. Which hospital is the most cost effective?
Hospital Average Charge Case-mix Index
Bellevue Hospital $4,590 .8788
Renton Hospital $5,780 1.235
The average case-mix adjusted charge for Bellevue Hospital is $4,590/.8788 = $5,223.03.
The average case-mix adjusted charge for Renton Hospital is $5,780/1.235 = $4,608.16.
Renton is more cost effective!

Supplement Thirteen
Rolling up Standard Procedure Costs to Determine Product Costs
![Page 14: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/14.jpg)
Review
Wes Douglas’ Approach to Saving Peter Brannan Community Hospital
![Page 15: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/15.jpg)
He focused first on primary factors driving health care costs• Studied medical economics
– Impact of technology and duplication– Lack of market mechanism– Price inelasticity– Disparate information– Adverse incentives traditional
reimbursement
• Evaluated one approach to problem--managed care
![Page 16: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/16.jpg)
Next he focused internally
• Analyzed existing costs– Direct labor--hospital association data
and Alma Cowdrey study– Direct materials--review of materials
management function
• Evaluated revenues– Volume– Pricing
![Page 17: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/17.jpg)
Initiated the design of cost accounting system for PBCH• Reviewed theory and practice of cost
accounting in manufacturing – Identified elements he wanted (standard
costing, job-order and process-costing functions
• Evaluated information needs of managers
• Defined three levels of product detail
![Page 18: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/18.jpg)
Initiated the design of cost accounting system for PBCH• Developed methodologies to
determine– Standard labor hours– Standard labor rates– Standard costs for direct materials– Standard costs for hospital overhead
• Investigated case-mix system
![Page 19: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/19.jpg)
Next Step
• Cost roll-ups• Preparation of management
reports
![Page 20: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/20.jpg)
Final Products
• Individual DRGs• Capitation days
Both are calculated by creating resource consumption profiles, then rolling up the costs of component primary and intermediate products.
![Page 21: Chapter 23 Includes Supplements 12 through 13. Supplement Twelve The Use of Case-Mix in Assessing Efficiency.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e685503460f94b64745/html5/thumbnails/21.jpg)
To Calculate Capitation Payment• It is necessary to identify the
demographic characteristics of each of the employers participating in capitation payment– Hire an actuary to identify the number of
hospitalizations per 1,000 enrollees– From this data project cost per employer– Divide this number by the number of
capitation months each employer will pay
