Discount Adjustment Factor. An adjustment was also applied to some HC-reported expenditure data because an evaluation of matched HC/MPC data showed that respondents who reported that charges and payments were equal were often unaware that insurance payments for the care had been based on a discounted charge. To compensate for this systematic reporting error, a weighted sequential hot-deck imputation procedure was implemented to determine an adjustment factor for HC-reported insurance payments when charges and payments were reported to be equal. As for the other imputations, selected predictor variables were used to form groups of donor and recipient events for the imputation process.

Expenditure data for newborns were edited to exclude discharges after birth when the newborn left the hospital on the same day as the mother. As a result, inpatient expenditures reported for 1997 births were usually applied to the mother and not treated as separate expenditures for the infant. However, if a newborn was discharged at a later date than the mother, then the hospitalization was treated as a separate hospital stay for the newborn. This means that in most cases, expenditure data for the newborn is included on the mother’s record. A separate record for the newborn only exists if the newborn was discharged after the mother. In this case, the expenditure for the newborn is on the newborn’s record. In addition, the user should note that for the purposes of the expenditure imputation, deliveries were identified using the variable RSNINHOS which has not been reconciled with pregnancy and delivery ICD-9 codes on this file as well as on HC-018. As mentioned previously, in most instances where RSNINHOS = 4 delivery, the ICD-9 code indicates a pregnancy rather than a delivery. Although a person may have indicated that there was an emergency room visit that preceded this hospital stay (EMERROOM), there was no verification that, in fact, the emergency room visit was actually recorded within the Emergency Room Section of the questionnaire. While it is true that all of the event files can be linked by DUPERSID, there is no unique record link between hospital inpatient stays and emergency room visits. That is, a person could have one hospital inpatient stay and three emergency room visits during the calendar year. While the hospital inpatient stay record may indicate that it was preceded by an emergency room visit, there is no unique record link to the appropriate (of the three) emergency room visit.
