Common use of Utilization Variables (OBNUM Clause in Contracts

Utilization Variables (OBNUM. RXNUM) The variables OBNUM, OPNUM, HHNUM, IPNUM, ERNUM, and RXNUM indicate the total number of 2011 events that can be linked to each condition record on the current file, i.e., office- based, outpatient, home health, inpatient hospital stays, emergency room visits, and prescribed medicines, respectively. These counts of events were derived from Expenditure Event Public Use Files (HC-144G, HC- 144F, HC-144H, HC-144D, HC-144E, and HC-144A). Events associated with conditions include all utilization that occurred between January 1, 2011 and December 31, 2011. 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 inpatient hospital stay and was treated for a fractured hip, a fractured shoulder and a concussion, each of these conditions has a unique record in this file and IPNUM=1 for each record. By summing IPNUM for these records, the total inpatient hospital stays would be three when actually there was only one inpatient hospital stay for that person and three conditions were treated. These variables are useful for determining the number of inpatient hospital stays for head injuries, hip fractures, etc.

Utilization Variables (OBNUM. RXNUM) The variables OBNUM, OPNUM, HHNUM, IPNUM, ERNUM, and RXNUM indicate the total number of 2011 2014 events that can be linked to each condition record on the current file, i.e., office- based, outpatient, home health, inpatient hospital stays, emergency room visits, and prescribed medicines, respectively. These counts of events were derived from Expenditure Event Public Use Files (HC-144HC-168G, HC- 144F168F, HC-144HHC-168H, HC-144DHC-168D, HC-144EHC-168E, and HC-144AHC-168A). Events associated with conditions include all utilization that occurred between January 1, 2011 2014 and December 31, 20112014. 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 inpatient hospital stay and was treated for a fractured hip, a fractured shoulder shoulder, and a concussion, each of these conditions has a unique record in this file and IPNUM=1 for each record. By summing IPNUM for these records, the total inpatient hospital stays would be three when actually there was only one inpatient hospital stay for that person and three conditions were treated. These variables are useful for determining the number of inpatient hospital stays for head injuries, hip fractures, etc.

Events associated with conditions include all utilization that occurred between January 1, 2011 2007 and December 31, 20112007. 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 inpatient hospital stay and was treated for a fractured hip, a fractured shoulder and a concussion, each of these conditions has a unique record in this file and IPNUM=1 for each record. By summing IPNUM for these records, the total inpatient hospital stays would be three when actually there was only one inpatient hospital stay for that person and three conditions were treated. These variables are useful for determining the number of inpatient hospital stays for head injuries, hip fractures, etc.

Events associated with conditions include all utilization that occurred between January 1, 2011 2010 and December 31, 20112010. 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 inpatient hospital stay and was treated for a fractured hip, a fractured shoulder and a concussion, each of these conditions has a unique record in this file and IPNUM=1 for each record. By summing IPNUM for these records, the total inpatient hospital stays would be three when actually there was only one inpatient hospital stay for that person and three conditions were treated. These variables are useful for determining the number of inpatient hospital stays for head injuries, hip fractures, etc.
