Operation Iraqi Freedom Analysis of VA Health Care Utilization -- Report 7 VHA Office of Public Health and Environmental Hazards, July 22, 2004 Summary Among 168,528 veterans of Operation Iraqi Freedom who have separated from active military duty, 16% (27,571) have sought health care from the Department of Veterans Affairs (VA) since deployment. For another gauge of VA health care utilization, 7,916 Iraqi Freedom veterans had one or more VA healthcare visits in April 2004, which represents an average workload during that one month period of approximately 50 veterans treated in each of 158 VA hospitals. 57% of Iraqi Freedom veterans who received VA health care have been members of the Reserve/National Guard. Veterans of Operation Iraqi Freedom have presented to the VA with a wide range of both medical and psychological conditions, which have encompassed over 3,800 discrete diagnoses. The most common health problems of veterans of Operation Iraqi Freedom have been musculoskeletal ailments, principally joint and back disorders, and dental problems. The frequency of the diverse types of diagnoses received by these 27,571 veterans has not changed substantially since the last update of this report on May 19, 2004. Although health care utilization data does not represent a formal epidemiological study, no particular health problem stands out among Iraqi Freedom veterans at present. Consequently, recommendations cannot be provided for particular testing or evaluation; these war veterans should be assessed individually to identify all outstanding health problems. The Veterans Health Administration (VHA) will continue to monitor the health status of recent Iraqi war veterans using updated deployment lists provided by DoD to ensure that VA tailors its health care and disability programs to meet the needs of this newest generation of war veterans. 1 Lists of Recent War Veterans VHA’s Environmental Epidemiology Service (EES-135) has been working with DoD to obtain a complete roster of recent combat veterans. To date, the DoD Defense Manpower Data Center (DMDC) has created a preliminary file of the Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) troops using Active Duty and Reserve Pay files, and Combat Zone Tax Exclusion and Imminent Danger Pay data fields. On September 22, 2003, DoD sent EES the first partial list of Iraqi war veterans who had “separated” from active duty but not the complete roster of deployed troops. The eighth, most recent, update of these deployment lists was provided to EES on June 23, 2004. For the purposes of this analysis, all these lists were merged by EES to form a single roster of separated veterans who had participated in Operation Iraqi Freedom (Figure 1). EES has noted certain discrepancies in the data both within and between these deployment lists, which could affect some analyses of clinical care. DMDC plans to address these data discrepancies in future roster preparations. The combined database provides basic military and demographic data on 168,528 unique service members who served in Operation Iraqi Freedom since October 1, 2003, and have been separated from active military service: 50,705 active duty and 117,823 Reserve or National Guard unit members (Tables 1 and 2). The DoD file did not include actual date of separation for everyone but the last out-of-theater date was March 2004, for active duty personnel and March 2004, for members of the Reserve/National Guard. VA Health Care Utilization Among all 168,528 separated Iraqi Freedom veterans, 27,571 (16.4%) had sought health care at a VA medical facility during fiscal years 2003 and 2004 (Table 3). Of those, 489 (0.3%) had been hospitalized at least once. Fifty-seven percent of veterans who received VA health care have been members of the Reserve/National Guard (Table 4). VISN 8 in Florida (VA Sunshine Healthcare Network) has seen the highest percentage (10.3%) of Iraqi Freedom veterans (Table 5). The percentage of separated Iraqi Freedom veterans who had sought VA health care has continued to increase since the last report, which was based on the roster received on April 16, 2004, from 15% (21,021 of 139,778 separated veterans) to 16% (27,571 of 168,528 separated veterans). This increase reflects continued enrollment of Iraqi Freedom veterans for VA health care, which is available free of charge for two years following separation from active military service for any health problem possibly related to deployment. As another gauge of VA health care utilization, in April 2004, 7,916 unique Iraqi Freedom veterans had one or more VA healthcare visits, which represents an 2 average workload of approximately 50 veterans treated in each of 158 VA hospitals during that one month, or less than 2 veterans per day. For comparison, more than 4.5 million individuals received care in VA healthcare facilities in 2002. And VA's outpatient clinics registered approximately 46.5 million visits. The 27,571 Iraqi Freedom veterans who have received VA health care in FY 2003/2004 therefore represents 0.6% of the total number of military veterans VA provided care for in 2002. Most Common Diagnoses Among Iraqi Freedom Veterans Of note, evaluated Iraqi Freedom veterans are not representative of deployed military personnel in general but are more typical of young, active, healthcareseeking populations. The following summary of diagnoses therefore does not represent an epidemiological study of all veterans recently deployed to Southwest Asia but does provide important clinical information about VA health care utilization of Operation Iraqi Freedom veterans. Veterans of Operation Iraqi Freedom are presenting to the VA with a wide range of both medical and psychological conditions. A total of 3,890 discrete, ICD-9 coded diagnoses were needed to characterized this predominantly outpatient population seeking health care following deployment. No particular diagnosis stood out as unusual among this broad range of health problems (Tables 6-21). The frequency of the types of diagnoses received by these 27,571 Iraqi Freedom veterans has not changed substantially since the previous analysis of 21,021 Iraqi Freedom veterans who had received VA health care. The most common, broad diagnostic categories are similar to those observed in the last report of May 19, 2004 (Table 6). Also, the most common specific diagnosis within broad ICD-9 categories changed little since the last report (Tables 7-21). Among the 27,571 Iraqi Freedom veterans evaluated by the VA, the most frequent diagnoses involved the musculoskeletal system (Table 6). There were 8,134 veterans who received this diagnosis (ICD 710-739), which is very common in young, active, military populations. Within this diagnostic category, joint and back disorders were most often found (Table 19). The second most frequent category of diagnoses involved the Digestive System (ICD 520-579), with teeth and gum problems predominating (Tables 6 and 16). In this population of veterans who served in a war zone and sought VA health care, 5,375 veterans were diagnosed with a mental health problem (Table 6). Within this group, PTSD was diagnosed among 1,641 Iraqi Freedom veterans (Table 12). It is critical to keep in mind that these statistics for mental health problems are preliminary and will change over time. Some troops may not have had an underlying mental health problem diagnosed at an initial clinical evaluation, and veterans may not develop mental health problems for months to years following wartime trauma. 3 Figure 1 Separated Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) Veterans as of June 23, 2004 Prepared by VHA EES (135) List 8 Active Duty File: N=61,602 records; date received, June 23, 2004 List 8 Reserve Files: N=128,435 records; date received, June 23, 2004 Combined List of 190,037 records 134,316 unique veterans List 1 & 2 -Sep 22, 2003 Nov 21, 2003 List 3 & 4 -Dec 22, 2003 Feb 12, 2004 List 7 -May 18, 2004 Total Separated Iraqi Freedom Veterans N=168,528 List 5 & 6 -Mar 22, 2004 Apr 16, 2004 Mortality Iii in-theater: 716 Veterans Combined Lists 1, 2, 3, 4, 5, 6, 7 & 8 194,686 unique veterans Note: 10.1% of Veterans (19,722) Served in both Operations Total Separated Enduring Freedom Veterans N=45,880 4 Combined Deployment Lists, Health Care Utilization, and Diagnostic Tables Table 1 Distribution of Separated Personnel Identified on the DoD Lists1 of Enduring Freedom (OEF) and Iraqi Freedom (OIF) Participants By Operation and Component Type Service Component Type Military Operation Active Duty 2 Reserve/Guard 3 Total 4 Enduring Freedom Male Female Unknown Gender 4,614 4,129 309 176 41,266 37,272 3,992 2 45,880 41,401 4,301 178 Iraqi Freedom Male Female Unknown Gender 50,705 45,177 5,121 407 117,823 105,393 12,418 12 168,528 150,570 17,539 419 Total Veterans 5 Male Female Unknown 53,200 47,450 5,309 441 141,486 126,527 14,946 13 194,686 173,977 20,255 454 1 2 3 4 5 DMDC approved lists received September 22, 2003, November 21, 2003, December 22, 2003, February 12, 2004, March 22, 2004, April 16, 2004, May 18, 2004 and June 23, 2004 were combined to generate a composite list of unique veterans.
