1 The Healthcare Cost and Utilization Project (HCUP) Tools and Products Agency for Healthcare Research and Quality APHA CEI Session  November 2006

2 Advancing Excellence in Health Care 2 Healthcare Cost and Utilization Project (HCUP) THE LARGEST COLLECTION OF MULTI-STATE, ALL-PAYER, ENCOUNTER-LEVEL, HEALTH CARE DATA

3 Advancing Excellence in Health Care 3 HCUP Tools

4 Advancing Excellence in Health Care 4 Current HCUP Tools Clinical Classifications Software (CCS) ComorbiditySoftwareProcedureClasses Cost-to-ChargeRatios AHRQ Quality Indicators (QI) Chronic/Non-ChronicIndicator

5 Advancing Excellence in Health Care 5 Most AHRQ HCUP Tools Can Be Applied to Any Administrative Database SASD SEDD NIS KID SID Other Administrative Databases CCS Tools Comorbidity Procedure Classes Chronic Condition Indicator AHRQ QIs

6 Advancing Excellence in Health Care 6 The CCS collapses ICD-9-CM codes into a smaller number of clinically meaningful categories that can be more useful for presenting descriptive statistics than are individual ICD-9-CM codes Clinical Classifications Software 12,000 Diagnosis Codes and 3,500 Procedure Codes Clinical Classifications ICD-9-CM Diagnosis Codes

7 Advancing Excellence in Health Care 7 CCS Mapping Files The CCS Mappings are available for download on the HCUP User Support Website

8 Advancing Excellence in Health Care 8 CCS-CPT Categories CCS-CPT Software CPT Codes Groups CPT Codes into Clinically Meaningful Categories CCS-CPT Codes CCS 14: Glaucoma procedures CCS 6: Decompression peripheral nerve SASD SEDD

9 Advancing Excellence in Health Care 9 CCS - Mental Health and Substance Abuse (CCS-MHSA) Groups Codes into Clinically Meaningful Mental Health and Substance Abuse Categories Creates 14 MHSA diagnosis categories Some are broken into more specific diagnoses Adjustment disorders Mood disorders Anxiety disorders Personality disorders Disruptive behavior Schizophrenia Delirium, dementia Substance-related Developmental disorders Suicide Disorders in childhood Screening for MHSA Impulse control, NEC Miscellaneous CCS-MHSA Software

10 Advancing Excellence in Health Care 10 CCS Documentation

11 Advancing Excellence in Health Care 11 CCS Mappings – Appendix A of CCS User Guide An easy way to look at which ICD-9-CM diagnosis codes comprise each CCS category us.ahrq.gov/toolssoftware/ccs/AppendixAsingleDX.pdf

12 Advancing Excellence in Health Care 12 The Comorbidity Software is based on the ICD-9-CM coding scheme. This software creates about 30 variables that identify major comorbidities. Comorbidity Software ICD-9-CM Codes, DRGs on Administrative Data Comorbidity Software 30 Comorbidity Classifications

13 Advancing Excellence in Health Care 13 List of 29 Comorbidities 1. Congestive heart failure 2. Valvular disease 3. Pulmonary circulation disorders 4. Peripheral vascular disorders 5. Hypertension 6. Paralysis 7. Other neurological disorders 8. Chronic pulmonary disease 9. Diabetes w/o chronic complications 10. Diabetes with chronic complications 11. Hypothyroidism 12. Renal failure 13. Liver disease 14. Chronic Peptic ulcer disease 15. HIV and AIDS 16. Lymphoma 17. Metastatic cancer 18. Solid tumor without metastasis 19. Rheumatoid arthritis/ collagen vascular diseases 20. Coagulation deficiency 21. Obesity 22. Weight loss 23. Fluid and electrolyte disorders 24. Blood loss anemia 25. Deficiency anemias 26. Alcohol abuse 27. Drug abuse 28. Psychoses 29. Depression

14 Advancing Excellence in Health Care 14 Example: Obesity Comorbidity #21 Obesity ICD-9-CM codes: 2780, 27800, Discharge does not have these DRGs: Nutrition /metabolic ( ) or Obesity Proc (288)

15 Advancing Excellence in Health Care 15 Comorbidity Software Required Data Elements Data Element Type Length Length DRGNum3 DX1 (ICD-9-CM diagnosis code) Char5 DX2 – DXn (ICD-9-CM diagnosis codes) Char5 NDX (Number of diagnosis fields) Num3

16 Advancing Excellence in Health Care 16 Download the Comorbidity Software

17 Advancing Excellence in Health Care 17 Comorbidity: Format and Analysis Program

18 Advancing Excellence in Health Care 18 Format Program Creation of Format Library for Comorbidity Groups Creation of Format Library for Comorbidity Groups The format program defines a format library that contains the diagnosis screens necessary for the comorbidity analysis. It will be used by Program 2, the comorbidity analysis program.

19 Advancing Excellence in Health Care 19 Run Format Program in SAS

20 Advancing Excellence in Health Care 20 Analysis Program Creation of Comorbidity Variables The analysis program assigns to the inpatient records 0/1 indicators for the comorbidity variables of interest. Creation of Comorbidity Variables The analysis program assigns to the inpatient records 0/1 indicators for the comorbidity variables of interest.

21 Advancing Excellence in Health Care 21 Cost-to-Charge Ratios The Cost-to-Charge Ratios enable conversion of charge data to cost data on the NIS and the SID. Hospital-Level NIS/SID Data Apply Ratios $ Convert Charges to Costs

22 Advancing Excellence in Health Care 22 Variables in the CCR Files Six variables in the Cost-to-Charge data include: – – HOSPID: HCUP hospital identification number – – WI_X: Wage Index, source CMS, edited – – Z013: State postal code – – APICC: All-payer inpatient C/C, hosp-specific – – GAPICC: Group avg. all-payer inpatient C/C – – YEAR: Year for linking to HCUP records

23 Advancing Excellence in Health Care 23 Availability of Cost-to-Charge Files NIS NIS – 2003 – 2002 – 2001 SID SID – 2003 – 2002 – 2001 KID KID – 2003 For Most States

24 Advancing Excellence in Health Care 24 Hospital Market Structure (HSM) Files The HSM Files contain various measures of hospital market competition and are available free-of-charge from the HCUP Central Distributor.
