What does this data tell you? Section 4 appears to be a challenge; remember you must compare data to the national data and determine if there are any statistically significant differences at the 0.5 level. For Table 4-1, Information for national is given in table 4-4. You must then comment if it is statistically significant. For table 4-2 and 4-3 you can use formulas with data from table 4-4 (hints below) to find the national and comment if it is statistically significant. Here is a hint: Table 4-2: National Medicare Reimbursement/National Number of Discharges = Average National Reimbursement Hope that helps! Let me know if you have any questions. Table 4-1 Average Length of Stay (ALOS) Average Length of Stay (ALOS) DRG Hospital National Statistically Significant 088 4.6 5.0 (5.0-4.6 = 0.4 < 0.5) No 089 5.6 5.7 (5.7 - 5.6 = 0.1 < 0.5) No 213 10.0 9.1 276 3.6 4.7 302 7.9 8.2 478 7.4 7.3 (10.0 - 9.1 = 0.9 > 0.5) Yes (4.7 3.6 = 1.1 > 0.5) Yes (8.2-7.9 = 0.3 <0.5) No (7.4 -7.3 = 0.1< 0.5) No Table 4-2 Average Charges Average Charges DRG Hospital National Statistically Significant 088 $13,952 14,208 -.7901 Yes. 089 $16,205 16,384 -.8443 Yes. 213 $35,452 31,842 27.3485 Yes. 276 $11,842 12,225 -4.9103 Yes. 302 $68,235 104,433 478 $25,789 39,952 -524.6086 Yes. -143.0606 Yes.

For section 4, you do not have to multiply by 100 for the tables to determine national average charges and reimbursement. 2. To determine statistical significance, you will subtract the difference between the local and national and determine whether it is more or less than 5% or .05. For the $ numbers, you will have to subtract and divide to determine whether it is more or less than 5%. Section 4 Your Chief Financial Officer (CFO) has asked you to gather some information for him. He wants to know the average length of stay (ALOS), average charges, and average reimbursement for specific DRGs. He wants you to compare this data to the national data and determine if there are any statistically significant differences at the 0.5 level. Calculate the ALOS information using Table 4-1. Calculate the average charges information using Table 4-2. Calculate the average reimbursement information using Table 4-3. Use the national data on these DRGs that is presented in Table 4-4. The number of patients at our facility for each DRG is: DRG Number of Patients DRG 88 324 DRG 89 212 DRG 213 132 DRG 276 78 DRG 302 69 DRG 478 99
