1. How to read the Product Line/Market Share Report Parameters
The Product Line/Market Share Report Parameters are used in conjunction with the Product Line and Market Share Report. This report identifies the hospitals that treat patients from your service areas, the zip codes that make up your service areas and the product lines within your hospital. Page 1 shows the hospitals you have selected to include in your peer group as well as the primary, secondary, and extended zip code service areas you have selected. If your hospital has not selected peer groups or other zip code service areas, these fields will state that no hospitals or zip codes have been submitted (see example below). Pages 2 to the end of the report show the product lines selected for each MDC group or product line group. If no specific DRGs are selected by your facility, CHA will use the default settings. This report offers you a chance to review your parameters and offers you the opportunity to make modification to them once a year. Please contact Krista Smith (720) or by at if you would like to modify these parameters.

These are the DRGs group assignments for the product lines selected.

2. How to read the Product Line and Market Share Report
The Product Line & Market share report is broken down by DRGs, a combination of DRGs or MDCs known as product lines. It specifically shows the discharges, total patient days, average length of stay, average non-zero charge, and the case mix for specific hospitals. The main hospital it was run for is both in the heading of the report and is the first hospital listed(1). This allows you to compare the totals of your hospital with its peer hospitals. The columns on the report represent the respective DRG category or product line and the rows represent the hospital grouping of discharges, total patient days, average length of stay (ALOS), average non-zero charges, and case mix. Please refer to the key in the upper left hand corner as you read the report(2). 2 1

3. How to read the Zip Code Market Share Report
Unlike the Product Line & Market share report which is broken down by DRGs or a combination of DRGs or MDCs, this report is broken down by zip codes. It specifically shows the top 12 zip codes based on the number of discharges and an ‘All Other’ column containing summary totals of all other zip codes for your hospital. The main hospital it was run for is both in the heading of the report and is the first hospital listed(1). This allows you to compare the totals of your hospital with its peer hospitals. This is an all inclusive report based on the Primary & Secondary Service areas (zip codes) combined. The columns on the report represent the respective zip code and the rows represent the hospital grouping of discharges, total patient days, average length of stay (ALOS), average non-zero charges, and case mix. Please refer to the key in the upper left hand corner as you read the report(2). 1 2

4. How to read the Community Health Report
The Community Health Report gives you information on key community health indicators using inpatient data for your primary service area (as defined by your hospital for the CHA Discharge Data Product Line/Market Share Report). On the left hand side of the report are indicators grouped into major categories. In the Injury category the numbers refer to the number of patients with injuries defined by E-codes. In the Utilization category, found on page 2 of the report, the numbers refer to the number of patients defined by DRGs. Throughout the report ‘Cases’ refers to the number of patients admitted and discharged, ‘Population’ refers to the sum of the population in the relevant zip codes, and ‘Cases per 100,000’ refers to the number of patients per 100,000 population.

The E-Code groupings for injury mortality and morbidity within your hospitals primary and secondary zip code areas are shown in this report. One report presents the Inpatient only data and the other presents the Outpatient only data. Each report lists the Mechanism/Cause description in the left-most column and 3 breakouts for listing the Manner/Intent of injury. The first breakout illustrates the data for your hospital only within your primary and secondary zip code area listed on the bottom (If you have not submitted your preferred service area, this area will be blank as seen in example below) . The second breakout shows the data for all hospitals within your primary & secondary zip code areas (If you have not submitted your preferred service area, this area will be blank as seen in example below). The third breakout shows all the data for all hospitals in all areas of Colorado.

7. How to read the CHA DRG with without CC comparative Report
This report is used to compare your hospital’s DRGs with and without complication & co-morbidity ratio. You can compare your ‘CC Rate’ against All Medicare records in the CHA database, to All records with your same Medicare Payment Method (MPM), and to all hospitals within Colorado.

10. How to read the CHA Ski Related Accidents Report
This report is comprised of data from October through September of the following year and only shows those hospitals that have contributing data. It is broken down into both inpatients and outpatients and use 3 ski related injury E-codes. These include E885.3 – Fall from Skis; E885.4 – Fall from Snow Board; and E847 – Fall from Lift or Tow.

11. How to read the CHA Accuracy Report
This report indicates both the type and frequency of errors within each hospital’s discharge data sent to CHA. The (1) First set of pages lists the total of edits by the edit code and edit description. The (2) Second set of pages lists the total of edits by hospital and it includes the total discharges per hospital.

12. How to read the CHA Severity of Illness & Risk of Mortality Report
This report is broken down into 3 separate reports – All Patients (shown in example below), Patients 65 & Over, and Patients Under 65. Each 2 page report lists the hospitals alphabetically in their respective Medicare Payment Methodology (MPM) categories (Denver Metro, Other Urban, Rural, etc). Each detail line represents the corresponding number of discharges for the hospital by Severity of Illness and Risk of Mortality. These are broken down by Minor, Moderate, Major, and Extreme and are based on the results obtained from the 3M DRG grouper. Severity of Illness refers to the extent of physiologic decompensation or organ system loss of function whereas Risk of Mortality refers to the likelihood of dying.

13. How to read the CHA Medicare Inpatient One Day Visits Report
This report provides information for Medicare Inpatient One-Day Visits. The hospitals are listed in alphabetical order and each detail line provides a breakdown of all one-day discharges. The first column represents ALL one-day visits to the hospital (including non-Medicare). The remaining columns represent only Medicare one-day discharges along with the corresponding percent of the total one-day discharges. The Possible Re-Admission columns are derived by matching CHA discharge data records with similar data. For instance, readmissions ‘To Others’ matches those records were the patient’s DOB, Sex, and Zip Code are the same. Readmissions ‘W/I’ within the hospital includes the above matches plus adds the hospital medical record number. The percentages in columns 2 thru 6 are relative to the first ‘Total 1-Day Discharges’ column.

14. How to read the Case Mix Report By Age Groups
The Case Mix By Age Groups report shows case mix by age groups as well as Medicare Payment Methodology (MPM) categories. The case mix indices are based on Medicare weights. There is one specific report for acute care hospitals, and one for specialty hospitals. A case mix index is a factor that is used in cost outlier calculations that can range from 0 to It represents a way to compare the hospital resource use among hospitals. The higher the index the higher the expected resources required to treat the patient population for a given hospital. This report shows the case mix for 3 specific groups; all patients, those age 65 and over, and those under age 65.

15. How to read the Principal Procedure Outpatient Surgery Report
The Principal Procedure Outpatient Surgery Report shows the high volume principal procedure outpatient surgeries by hospital. The number of outpatients and average charge for the principal procedure is reported. This is broken down by All Patients, those 65 and over and those under 65 respectfully and also displays the hospitals alphabetically by category.

16. How to read the Hospital Charges and Average Length of Stay
by APR-DRG Report
This report gives information about hospital charges. Physician charge information is not included. In the top left-hand corner of each page is the APR-DRG number and name. A list of the 10 APR-DRGs in this report is found on the page following this instruction sheet. Hospitals are listed in alphabetical order within their peer groups: Denver Metro, Other Urban and Rural. A hospital is not listed if it did not treat patients in the given APR-DRG. Rehabilitation, psychiatric, specialty, and children’s hospitals are not included in this report.
Severity Levels: The DRG system assigns levels of severity, or how sick the patient is, by considering 1)The principal diagnosis, the main reason for admission to the hospital; 2) secondary diagnoses, underlying or complication conditions such as diabetes; 3) age; and 4) the presence of certain non-operating room procedures, such as dialysis.
The severity of illness levels are: minor, moderate, major and extreme. A minor severity of illness category is one relatively without complications or secondary diagnoses that would consume additional resources. Moderate, major and extreme levels will each have additional factors that make the illness worse and that will require additional resources to provide care.
# of Patients: This shows the number of patients in each of the severity levels and the total number of patients treated in this DRG for each hospital.
Length of Stay: Length of stay is shown by three numbers. ALOS is the average length of stay by patients in each severity level and for all patients. The Low and High numbers are the statistical standardized range. There is a 95% probability that the expected length of stay lies within these numbers.
Total Charges: Total charges are shown by three numbers. AVG CHG is the average charge for patients in each severity of illness level and for all patients. These are hospital charges and, in most cases, do not include separate physician charges. The Low and High numbers are the statistical standardized range. There is a 95% probability that the expected length of stay lies within these numbers.
