On the top of the slide are the logos for the Department of Health & Human Services and the AHRQ logo. The Department of Health & Human Services logo is an artistic image of an eagle with the outlined profile of faces. The AHRQ logo reads, "AHRQ - Agency for Healthcare Research and Quality: Advancing Excellence in Health Care, www.ahrq.gov"
Slide 1
AHRQ Quality Indicators (QIs)
This presentation uses a template with a blue background and a header with the AHRQ and Department of Health & Human Services logos on the left. The header and body of the slide are separated by a light blue horizontal line that traverses 80 percent of the slide from the left.
• Use existing hospital discharge data, based on readily available data elements
• Incorporate severity adjustment methods (APR-DRGs, comorbidity groupings and hierarchical modeling)
• Five modules: Inpatient, Patient Safety, Prevention, Pediatric, and Neonatal
Slide 2
Preventable Hospitalization Costs: A County-Level Mapping Tool
The PHC tool is a new QI software application designed to help organizations to:
• Better understand geographical patterns of potentially preventable hospital admission rates for selected health problems.
• Allocate resources more effectively by calculating potential cost savings if admission rates are reduced.
Slide 3
Main Functions of the PHC Tool
• Creation of maps that show the rates of hospital admission for selected health problems on a county-by-county basis.
• Calculation of potential cost savings that may occur if the number of hospital admissions for selected health problems in each county is reduced.
• Ability to place additional information about local populations onto maps to indicate the number of persons who are at greatest risk for those health problems in each county.
Slide 4
It processes all Prevention QIs...
• PQI 1 Diabetes Short-term Complications Admission Rate
• PQI 2 Perforated Appendix Admission Rate
• PQI 3 Diabetes Long-term Complications Admission Rate
• PQI 5 Chronic Obstructive Pulmonary Disease Admission Rate
• PQI 7 Hypertension Admission Rate
• PQI 8 Congestive Heart Failure Admission Rate
• PQI 9 Low Birth Weight Rate
• PQI 10 Dehydration Admission Rate
• PQI 11 Bacterial Pneumonia Admission Rate
• PQI 12 Urinary Tract Infection Admission Rate
• PQI 13 Angina without Procedure Admission Rate
• PQI 14 Uncontrolled Diabetes Admission Rate
• PQI 15 Adult Asthma Admission Rate
• PQI 16 Lower-extremity Amputation Rate among Diabetic Patients
There is no longer a PQI 4 and PQI 6.
Slide 5
and all area-level Pediatric QIs
• PDI 14 Asthma Admission Rate
• PDI 15 Diabetes Short-term Complications Admission Rate
• PDI 16 Gastroenteritis Admission Rate
• PDI 17 Perforated Appendix Admission Rate
• PDI 18 Urinary Tract Infection Admission Rate
Slide 6
Applying the QIs
• To calculate area rates it was necessary to have access to the state and county data.
• The software produces observed and risk-adjusted rates for all PQIs and PDIs.
• Output converted to rates
-Rates expressed either per 100 population and per 10,000 population
Slide 7
This slide shows a map of uncontrolled diabetes admission (2001, PQI14) in California. The map is broken down by county and is color-code to show different categories of rates per 10,000 people. The first category is 0.02-0.36, the second category is 0.4-0.74, the third category is 0.77-1.97, the fourth category is 2.46-8.68, and the fifth category is 8.69-144.21. The southern part of California has the lowest rate (0.02-0.36). The eastern part of the state has the highest rate (8.69-144.21). The map also uses an indicator shaped like a person to show the number of people age 18 and over in a given area. The larger the person indicates the more people in an area. The smallest person indicator represents 55-143 people. The next indicator represents 145-224 people. The largest person indicator represents 231-445 people.
Slide 8
Map Interpretation - Example
This slide shows a map of congestive heart failure admission rate (PQI 8), 2002 in the state of Michigan. The map is broken down by county and is color-code to show different categories of rates for 100,000 population. This slide shows how to interpret this kind of map. At the top of the map will be the name of the indicator and the date year in the map title. Along side of the state map will be a map key indicating the data quintiles and what colors are used to represent each quintile. Sometimes on the maps, symbols in the shape of a person are used to indicate the number of people in an area. The larger the person symbol, the more people are indicated in that area.
Slide 9
Data Interpretation
This slide shows a screen shot of a printout of all AHRQ PQIs by county for the state of Michigan. The print out shows how you can compare each county's rate to the overall state rate and how you can also look the upper and lower confidence intervals for each county.
Slide 10
Cost Data Interpretation
This slide shows the print out of an Excel spreadsheet. At the top of the spreadsheet is the QI Name. In this case, it is "Chronic Obstructive Pulmonary Disease (PQI 5). Below it is the county number, county name, mean cost for the QI specified, total number of cases, and total cost. Next to this data is the potential cost savings if the number of admission were reduced by a specific percentage. In this case, the percentages used were 10%, 20%, 30%, 40%, and 50%.
