a. Advantages of Placing the WWR on the IDB.
(1) The WWR provides aggregate and individual patient level detail on:
(a) patients receiving inpatient, outpatient, and ambulatory procedure
(b) aggregate ancillary services counts; and
(c) service specific and non-MEPRS workload.
(2) The WWR information is available as soon as 5, but not later than 21,
working days after the end of the reporting period if the Service opts to place the WWR on
the IDB and edit it rather than transmitting to the IDB by the 15th of the month. Thus, data
are available for corporate reports very quickly.
(3) At the LA Regional IDB, the WWR will enable a first order assessment of
the completeness of direct care data received through the Source Data Collection System

Standard Ambulatory Data Record (SADR), and MEPRS records.
(4) The WWR can provide at least monthly validation of SDCS inputs at the
(5) Table 1-1 summarizes the SDCS inputs and the audit trail the WWR
(6) The WWR can provide the IDB management benchmark tables for all

(7) Once placed on the IDB, the CSD, CEIS Program Office, can use the WWR
and assist MTFs and all corporate levels in confirming the timeliness, completeness, and
validity of CEIS data using corporate approved metrics. The WWR is an excellent data
quality control tool for five reasons:
(a) The WWR is a Tri-Service developed standard providing aggregated
biostatistical workload data.
(b) The CHCS WWR provides an excellent audit for admissions, bed and
sick days, and inpatient, outpatient, and ambulatory procedure visit validation. Two patient
level detail and audit products run behind the CHCS WWR.
