This section describes the procedures used to assess data quality for each data source participating in HCUP.

This section describes the procedures used to assess data quality for each data source participating in HCUP.

Edit procedures were applied to HCUP data. Editing followed explicit rules:

• Make the data usable without extensive further editing.
• Confirm that data values are valid, internally consistent, and consistent with established norms, when feasible.
• Use some edit procedures to set questionable and inconsistent values to inconsistent (.C or negative 6-filled). Use other edit procedures only to tabulate edit failures. Use the latter to evaluate whether systematic problems exist.
• Never "fix" or impute data. Set invalid or inconsistent values to special missing values. This preserves the analyst's ability to investigate data anomalies.
• Some data elements are more important than others because:


• they are coded more reliably because they relate to reimbursement; and
• without these data elements, a discharge record is not useful for most analytic purposes.

Therefore, values of these data elements should be retained even in the presence of conflicting information. In order of importance, these data elements are:


1. Discharge date (and within discharge date: year, month, and day)
2. Admission date
3. Principal diagnosis

(Note: dates are not released on the HCUP databases, but these variables are used to create and verify other data elements such as length of stay and age.)


• Tabulate instances of edit failures and use these to assess data quality for each data source.

The following statistics were reviewed by an independent contractor for each year and data source (or for each different layout if the source changed file layouts during the year):

• For all numeric data elements - means, number of missing and no-missing values, minimum, and maximum.
• For all categorical and some continuous data elements - frequency distributions.
• For closely related data elements (e.g., admission source compared to admission type) - cross frequencies.

The following procedures were applied to each discharge record:

• To assess validity of values -


For numeric data:
• Verify numeric data as numeric.
• Check the range against legal values documented by the data source.
• Check the range against standard norms (e.g., length of stay is a non-negative value; age in years is between 0 and 124, the maximum allowed by the DRG grouper).
• Check the values against the maximum allowed for the data element (e.g., birth weight less than 20 pounds).

For character data:
• Verify against norms, when feasible (e.g., diagnosis codes and procedure codes).


• To assess internal consistency -


Compare values of related data elements (e.g., a procedure of hysterectomy should appear with a sex of female; admission date should occur before discharge date).

If an inconsistency involves a critical data element (such as discharge date, admission date, or principal diagnosis), retain the critical data element according to the established hierarchy. For example:
• If discharge date falls before admission date, retain discharge date and set admission date and length of stay to inconsistent (.C or negative 6-filled).
• If discharge date is invalid (e.g., February 30), retain discharge quarter and discharge year.


• To assess consistency with established norms -


Compare values to an established norm (e.g., maternal diagnoses should occur with an age between 10 and 55 years).

Edit checks for the HCUP databases beginning in 1998 were updated after a review of the editing procedures performed by a number of the HCUP State Partners and Medicare. Summary counts and percentages of edit failures were calculated for every HCUP database. Edit check binary data elements were not retained on the HCUP files.

The following table lists all of the edit checks performed on the HCUP databases starting in 1998 data. For each edit check there is a edit check number (e.g., EAGE01), a description of the edit check, and a description of the action that is taken if the record fails the edit check. HCUP uses many diagnosis and procedure screens to define specific conditions employed in the editing procedures. These screens are defined in the section Diagnosis and Procedure Screens.

Edit Check	Description	Action
Summary
EANY	ANY EDIT Summary edit check that indicates that any edit has been triggered.	For tabulation purposes only
Age and Date of Birth
EAGE01	DATA OF BIRTH MISSING OR INVALID The date of birth (DOB) is missing (.) or invalid (.A)	For tabulation purposes only
EAGE02	DATE OF BIRTH IS AFTER ADMISSION DATE The date of birth (DOB) is greater than the admission date (ADATE) causing the age in years (AGE) to be negative.	Set DOB and AGE to inconsistent (.C). AGEDAY and AGEMONTH are set to missing (.).

Retain age on a combined neonatal/maternal record.	Set offending DXn to "incn" and corresponding DXCCSn to inconsistent (.C). If NEOMAT ne 3, set - AGE to inconsistent (.C), - AGEDAY to inconsistent (.C), and - AGEMONTH to inconsistent (.C).
EAGE05	MATERNAL DIAGNOSIS OR PROCEDURE INCONSISTENT WITH AGE A diagnosis (DXn) or procedure (PRn) on the record satisfies the MATERNAL screen, and the nonmissing age in years (AGE) is less than 10 or greater than 55. Retain age on a combined maternal/neonatal record.	Set offending DXn/PRn to "incn" and corresponding DXCCSn/PRCCSn to inconsistent (.C). If NEOMAT ne 3, set - AGE to inconsistent (.C), - AGEDAY to inconsistent (.C), and - AGEMONTH to inconsistent (.C).

Edit checks for the 1988-1997 HCUP databases were developed during the HCUP Feasibility Study (AHCPR Hospital Cost Database Feasibility Study, Contract No. 282-90-0029). Edit check binary data elements that identify inconsistencies between related data elements on the same record were retained on some HCUP databases. The edit check data elements (EDnnn) have the following values:

0	The problem was not found, or the edit check was not applicable.
1	The record failed the edit check.

To conserve space on the restricted access public release HCUP files, the edit check data elements were not included.

The following table lists all of the edit checks performed on the HCUP databases in the 1988-1997 data. For each edit check the edit check number (e.g., E010) corresponds to the edit check data element. Included in the table is a description of the edit check and the action that is taken if the record fails the edit check. HCUP uses many diagnosis and procedure screens to define specific conditions employed in the editing procedures. These screens are defined in the section Diagnosis and Procedure Screens.

The diagnosis and procedure screens used in HCUP data processing are specified below. The screens have been updated for ICD-9-CM coding changes to diagnoses and procedures through fiscal year 2007 (ending date September 30, 2007). Changes to the screens across years are underlined.

Screen used for 1988 to 1993 calendar year data:
Diagnoses 630 to 67694; V220 to V242; and V270 to V279. Procedures 720 to 7599.

Screen used for 1994 to 1996 calendar year data:
Diagnoses 630 to 677; V220 to V242; and V270 to V279. Procedures 720 to 7599.

Screen used for 1997 calendar year data:
Diagnoses 630 to 677 (excluding 655.7, 655.71, 655.73); 7965; V220 to V242; and V270 to V279. Procedures 720 to 7599.

Note: Codes 655.7 (valid until September 1997), 655.71, and 655.73 (valid as of October 1997) were erroneously excluded in the 1997 maternal screen. This would cause ED4nn "Maternal Diagnosis Inconsistent with Age" to not be set if a discharge with any of these diagnoses and an age less than 10 or greater than 55. This omission was corrected starting with 1998 data.

Screen used beginning with 1998 - 2001 calendar year data:
Diagnoses 630 to 677; 7965; V220 to V242; and V270 to V279. Procedures 720 to 7599.

Screen used for 2002-2003 calendar year data:
Diagnoses 630 to 677; 7965; V220 to V242; and V270 to V279. Procedures 720 to 7537, 754 to 7599.

Screen used beginning with 2004 calendar year data:
Diagnoses 630 to 677; 7965; V220 to V242; V270 to V279; and V6511. Procedures 720 to 7537; and 754 to 7599.

Screen used beginning with 2006 calendar year data:
Diagnoses 630 to 677; 7923, 7965, V220 to V242; V270 to V282; V286, V616 to V617; V6511, and V7242. Procedures 720 to 7537; and 754 to 7599.

Note: Beginning with calendar year 2006, we compared the HCUP maternal screens to the Medicare Code Edits and adjusted the HCUP edit screens as appropriate for HCUP processing.

Screen used for 1988 to 1993 calendar year data:
Diagnoses 7600 to 7799; and V3000 to V392.

Screen used for 1994-1995 calendar year data:
Diagnoses 75983; 7600 to 7799; and V3000 to V392.

Note: Code 75983 was erroneously included in the neonate screen. Because this is a rare condition, only a negligible number of records should be affected.

Screen used for 1996-1999 calendar year data:
Diagnoses 7600 to 7799; and V3000 to V392.

Screen used beginning with 2000 calendar year data:
Diagnoses 7620 to 7785; 7787 to 7799; and V3000 to V392.

Note: maternal conditions affecting the fetus (760 to 761) and congenital hydrocele (7786) were removed from the neonate screen because these conditions are sometimes coded for children more than one year old.

Screen used for 2001-2004 calendar year data:
Diagnoses 27701, 7620 to 7706; 7708 to 7785; 7787 to 7799; V290 to V299; and V3000 to V392.

Note: chronic respiratory disease arising in the perinatal period (code 7707) was removed from the neonate screen because this diagnosis code is often used even after the first year to indicate a condition originating in the perinatal period.

Screen used beginning with 2005 calendar year data:
Diagnoses 27701, 7620 to 7706; 7708 to 7785; 7787 to 7799; 7966; V290 to V299; and V3000 to V392.

Screen used beginning with 2006 calendar year data:
Diagnoses 27701, 74783, 76077 to 76078; 7620 to 7706; 7708 to 7785; 7787 to 7796; 77981 to 7799; 7966, and V290 to V392.

Note: Beginning with calendar year 2006, we compared the HCUP neonate screens to the Medicare Code Edits and adjusted the HCUP edit screens as appropriate for HCUP processing.

Note: Beginning with 1998 calendar year data, the HCUP edit checks were revised and the perinate screen was no longer used or updated.

Screen used from 1988-1997 calendar year data:
Diagnoses 7400 to 7799.

Note: Beginning with 1998 calendar year data, the HCUP edit checks were revised and the long-term-care indication screen was no longer used or updated.

Screen used for 1988 to 1992 calendar year data:
Diagnoses 2900 to 30503; 30520 to 3124; 3219 to 319; 3440; 430 to 438; and 797 to 7999.

Screen used for 1993 calendar year data:
Diagnoses 2900 to 30503; 30520 to 3124; 3219 to 319; 3440; 34481; 430 to 438; 44024, 4416, 78003, and 797 to 7999.

Note: Codes 78001, 78002, and 78009 were erroneously excluded from the long-term care screen. This would cause some discharges with long length of stays (over 365 days) to have ED601 "Long Length of Stay, Unjustified" set instead of ED600 "Long Length of Stay, Justified."

Screen used for 1994 calendar year data:
Diagnoses 2900 to 30503, 30520 to 3124, 3129 to 319, 34400 to 34409, 34481, 430 to 438, 44024, 4416, 78003, 797 to 7999.

Note: Codes 78001, 78002, 78009, 31281, 31282, and 31289 were erroneously excluded from the long-term care screen. This would cause some discharges with long length of stays (over 365 days) to have ED601 "Long Length of Stay, Unjustified" set instead of ED600 "Long Length of Stay, Justified."

Screen used for 1995 calendar year data:
Diagnoses 2900 to 30503, 30520 to 3124, 3129 to 319, 34400 to 34409, 34481, 430 to 4352, 4358 to 438, 44024, 4416, 78003, 797 to 7999.

Note: Codes 78001, 78002, 78009, 31281, 31282, 31289, and 4353 were erroneously excluded from the long-term care screen. This would cause some discharges with long length of stays (over 365 days) to have ED601 "Long Length of Stay, Unjustified" set instead of ED600 "Long Length of Stay, Justified."

Screen used for 1996 calendar year data:
Diagnoses 2900 to 319, 34400 to 34409, 34481, 430 to 438, 44024, 4416, 78001 to 78009, 797 to 7999.

Screen used for 1997 calendar year data:
Diagnoses 2900 to 319, 34400 to 34409, 34481, 430 to 4389, 44024, 4416, 78001 to 78009, 797 to 7999.

Screen used from 1988 to 1995 calendar year data:
Diagnoses 01660 to 01676, 05411 to 05412, 09815 to 09817, 09835 to 09837, 1121, 13101, 1740 to 1749, 179 to 1849, 1986, 2180 to 2219, 2331 to 2333, 2360 to 2363, 2560 to 2569, 30273, 30276, 30651 to 30652, 4566, 6115 to 6116, 6140 to 66942, 66944 to 67694, 71630 to 71639, 7520 to 75249, 7923, 7950, 8674 to 8675, 8784 to 8787, 90255 to 90256, 90281 to 90282, 9391 to 9392, 9474, 99632, V074, V1040 to V1044, V131, V220 to V235, V238 to V2501, V251, V253, V2541 to V2543, V255, V261, V270 to V289, V447, V524, V557, V723 to V724, V762.

Note: Starting in 1994 calendar year data, Codes 66943, 677, V237, V4551, V4552, and V5042 were erroneously excluded from the female screen. This would cause ED1nn "Diagnosis Inconsistent with Sex" to not be set when a male discharge had one of these female diagnoses.

Screen used for 1996 calendar year data:
Diagnoses 01660 to 01676, 05411 to 05412, 09815 to 09817, 09835 to 09837, 1121, 13101, 1740 to 1749, 179 to1849, 1986, 2180 to 2219, 2331 to 2333, 2360 to 2363, 2560 to 2569, 30273, 30276, 30651 to 30652, 4566, 6115 to 6116, 6140 to 677, 71630 to 71639, 7520 to 75249, 7923, 7950, 8674 to 8675, 8784 to 8787, 90255 to 90256, 90281 to 90282, 9391 to 9392, 9474, 99632, V074, V1040 to V1044, V131, V220 to V2501, V251, V253, V2541 to V2543, V255, V261, V270 to V289, V447, V4551 to V4552, V5042, V524, V557, V723 to V724, V762.

Note: Code E9672 was erroneously included in the female screen when processing 1996 calendar year data for all states and 1997 calendar year data for a few states. This would cause male discharges with the diagnosis E9672 (Child and adult battering and other maltreatment by mother or step mother) to have edit check ED1nn set to 1 and the diagnosis validity flag DXVn and SEX set to inconsistent (.C). Because this is a rarely used code, only a negligible number of records should be affected.

Screen used for 1997 calendar year data:
Diagnoses 01660 to 01676, 05411 to 05412, 09815 to 09817, 09835 to 09837, 1121, 13101, 1740 to 1749, 179 to1849, 1986, 2180 to 2219, 2331 to 2333, 2360 to 2363, 2560 to 2569, 30273, 30276, 30651 to 30652, 4566, 6115 to 6116, 6140 to 677, 71630 to 71639, 7520 to 75249, 7923, 7950, 7965, 8674 to 8675, 8784 to 8787, 90255 to 90256, 90281 to 90282, 9391 to 9392, 9474, 99632, V074, V1040 to V1044, V131, V1641, V220 to V2501, V251, V253, V2541 to V2543, V255, V261, V270 to V289, V447, V4551 to V4552, V5042, V524, V557, V723 to V724, V762.

Note: Code E9672 was erroneously included in the female screen when processing 1996 calendar year data for all states and 1997 calendar year data for a few states. This would cause male discharges with the diagnosis E9672 (Child and adult battering and other maltreatment by mother or step mother) to have edit check ED1nn set to 1 and the diagnosis validity flag DXVn and SEX set to inconsistent (.C). Because this is a rarely used code, only a negligible number of records should be affected.
