Common use of Utilization Variables (OBNUM Clause in Contracts

Utilization Variables (OBNUM. RXNUM) The variables are OBNUM, OPNUM, HHNUM, DVNUM, HSNUM, ERNUM, and RXNUM indicate the total number of 1997 medical provider events that can be linked to each condition record on the current file for each event type, i.e., office-based, outpatient, home health, dental, hospital stays, emergency room visits and prescribed medicines, respectively. These counts of events were derived from Medical Provider Event Public Use Files (HC-016A, HC- 016B, and HC-016D- HC-016H). Medical provider events associated with conditions include all utilization that occurred between January 1, 1997 and December 31, 1997. Because persons can be seen for more than one condition per visit, these frequencies will not match the person- or event-level utilization counts. For example, if a person had one hospital stay and was treated for a fractured hip and a fractured shoulder and a concussion, each of these conditions has a unique record and HSNUM=1 for each record. If you sum HSNUM for these records, then the total hospital stays would be 3 when actually there was only 1 hospital stay for that person and 3 conditions were treated. These variables are useful if you wanted to know the number of hospital stays for head injuries, hip fractures, etc.

Utilization Variables (OBNUM. RXNUM) The variables are OBNUM, OPNUM, HHNUM, DVNUMDNNUM, HSNUM, ERNUM, and RXNUM indicate the total number of 1997 2000 medical provider events that can be linked to each condition record on the current file for each event type, i.e., office-based, outpatient, home health, dental, hospital stays, emergency room visits visits, and prescribed medicines, respectively.

Medical provider events associated with conditions include all utilization that occurred between January 1, 1997 2000 and December 31, 19972000. Because persons can be seen for more than one condition per visit, these frequencies will not match the person- or event-level utilization counts. For example, if a person had one hospital stay and was treated for a fractured hip and a fractured shoulder and a concussion, each of these conditions has a unique record and HSNUM=1 for each record. If you sum HSNUM for these records, then the total hospital stays would be 3 when actually there was only 1 hospital stay for that person and 3 conditions were treated.

These counts of events were derived from Medical Provider Event Public Use Files (HC-016AHC- 026A, HC- 016B, HC-026B and HC-016D- HC-016HHC-026D - HC-026H). Medical provider events associated with conditions include all utilization that occurred between January 1, 1997 1998 and December 31, 19971998.

Utilization Variables (OBNUM. RXNUM) The variables are OBNUM, OPNUM, HHNUM, DVNUMDNNUM, HSNUM, ERNUM, and RXNUM indicate the total number of 1997 1999 medical provider events that can be linked to each condition record on the current file for each event type, i.e., office-based, outpatient, home health, dental, hospital stays, emergency room visits visits, and prescribed medicines, respectively. These counts of events were derived from Medical Provider Event Public Use Files (HC-016AHC- 033A, HC- 016B, HC-033B and HC-016D- HC-016HHC-033D - HC-033H). Medical provider events associated with conditions include all utilization that occurred between January 1, 1997 1999 and December 31, 19971999.

For example, if a person had one hospital stay and was treated for a fractured hip and a fractured shoulder and a concussion, each of these conditions has a unique record and HSNUM=1 for each record. If you sum HSNUM for these records, then the total hospital stays would be 3 when actually there was only 1 hospital stay for that person and 3 conditions were treated.
