Prevalence and Costs of Co-occurring Traumatic Brain Injury With and Without Psychiatric Disturbance and Pain Among Afghanistan and Iraq War Veteran VA Users

Background:Traumatic brain injury (TBI) is the “signature injury” in the Afghanistan and Iraq wars [Operation Enduring Freedom in Afghanistan (OEF)/Operation Iraqi Freedom (OIF)]. Patients with combat-related TBI also have high rates of psychiatric disturbances and pain. Objectives:To determine the prevalence of TBI alone and TBI with other conditions and the average cost of medical care for veterans with these diagnoses. Methods:Observational study using national inpatient, outpatient, and pharmacy data from Veterans Health Administration (VHA) datasets. Costs are estimated from utilization related to care within the VHA system. Participants were all OEF/OIF VHA users in 2009. Results:Among 327,388 OEF/OIF veterans using VHA services in 2009, 6.7% were diagnosed with TBI. Among those with TBI diagnoses, 89% were diagnosed with a psychiatric diagnosis [the most frequent being posttraumatic stress disorder (PTSD) at 73%], and 70% had a diagnosis of head, back, or neck pain. The rate of comorbid PTSD and pain among those with and without TBI was 54% and 11%, respectively. The median annual cost per patient was nearly 4-times higher for TBI-diagnosed veterans as compared with those without TBI (

Patients with these comorbidities incur substantial medical costs and represent a target population for future research aimed at improving health care efficiency.

Health care coverage and access to care: The status of Minnesota's veterans

CONTEXT Although numerous trials have evaluated efficacy of diet, fluid, or supplement interventions for secondary prevention of nephrolithiasis, few are included in previous systematic reviews or referenced in recent nephrolithiasis management guidelines. OBJECTIVE To determine efficacy and safety of diet, fluid, or supplement interventions for secondary prevention of nephrolithiasis. EVIDENCE ACQUISITION Systematic review and meta-analysis of trials published January 1950 to March 2008. Sources included Medline and bibliographies of retrieved articles. Eligible trials included adults with a history of nephrolithiasis; compared diet, fluids, or supplements with control; compared relevant outcomes between randomized groups (eg, stone recurrence); had > or = 3 mo follow-up; and were published in the English language. Data were extracted on participant and trial characteristics, including study methodologic quality. EVIDENCE SYNTHESIS Eight trials were eligible (n=1855 participants). Study quality was mixed. In two trials, water intake > 2 l/d or fluids to achieve urine output > 2.5 l/d reduced stone recurrence (relative risk: 0.39; 95% confidence interval: 0.19-0.80). In one trial, fewer high soft drink consumers assigned to reduced soft drink intake had renal colic than controls (34% vs 41%, p=0.023). Content and results of multicomponent dietary interventions were heterogeneous; in one trial, fewer participants assigned increased dietary calcium, low animal protein, and low sodium had stone recurrence versus controls (20% vs 38%, p=0.03), while in another trial, more participants assigned diets that included low animal protein, high fruit and fiber, and low purine had recurrent stones than controls (30% vs 4%, p=0.004). No trials examined the independent effect of altering dietary calcium, sodium, animal protein, fruit and fiber, purine, oxalate, or potassium. Two trials showed no benefit of supplements over control treatment. Adverse event reporting was poor. CONCLUSIONS High fluid intake decreased risk of recurrent nephrolithiasis. Reduced soft drink intake lowered risk in patients with high baseline soft drink consumption. Data for other dietary interventions were inconclusive, although limited data suggest possible benefit from dietary calcium.

Headache diagnoses among Iraq and Afghanistan war veterans enrolled in VA: a gender comparison.

Little research has been done on the validity of posttraumatic stress disorder (PTSD) diagnoses that are found in Department of Veterans Affairs (VA) administrative data, even though they are often used in VA research. We compared PTSD diagnoses found in VA administrative data with PTSD Checklist (PCL) scores self-reported by 4,777 newly diagnosed participants in a national postal survey study. Using PCL scores of at least 50 as the gold standard, we compared positive predictive values (PPVs) for at least one versus at least two PTSD diagnoses (found within 4 months of the first) in VA administrative data overall and by subgroups of interest: age, sex, and clinic where first diagnosed. The overall PPV was 75% for at least one PTSD diagnosis and 82% for at least two PTSD diagnoses. Similarly, the PPV significantly increased for all subgroup analyses when at least two PTSD diagnoses were used. The increase in PPV was greatest for those first diagnosed in primary care and for those older than 65. To select a sample of veterans with more definitive PTSD from administrative data, researchers should select those veterans with at least two PTSD diagnoses as opposed to at least one.

Using the Medicare Current Beneficiary Survey to conduct research on Medicare-eligible veterans

OBJECTIVES A systematic review of the cost-effectiveness of abdominal aortic aneurysm (AAA) repair was conducted. Although open surgery has been considered the gold standard for prevention of AAA rupture, emerging less-invasive endovascular treatments have led to increased interest in evaluating the cost and cost-effectiveness of treatment options. METHODS A systematic review of studies published in MEDLINE between 1999 and 2005 reporting the cost and/or cost-effectiveness of endovascular and/or open surgical repair of nonruptured AAAs was conducted. Case series studies with less than fifty patients per treatment were excluded. RESULTS Of twenty eligible articles, three were randomized controlled trials, twelve case series, four Markov models, and one systematic review. Regardless of time frame, all studies found that endovascular repair costs more than open surgery. Although the high cost of the endovascular prosthesis was partially offset by reduced intensive care, hospital length of stay, operating time, blood transfusions, and perioperative complications, hospital costs were still greater for endovascular than open surgical repair. For patients medically fit for open surgery, mid-term costs were greater for endovascular repair with no difference in overall survival or quality of life. For patients medically unfit for open surgery, endovascular repair costs more than no intervention with no difference in survival. CONCLUSIONS Although conclusions regarding the cost-effectiveness of AAA treatment options are time dependent and vary by institutional perspective, from a societal perspective, endovascular repair is not currently cost-effective for patients with large AAA regardless of medical fitness.

Objectives:The primary objective of this study was to examine veterans’ reliance on health care services provided by the Veterans Health Administration (VHA) within Minnesota and estimate the potential effect on uninsurance rates if all eligible veterans relied on VHA coverage. Secondary objectives were to compare veterans and nonveterans’ by geographic location, demographic characteristics, health status, and health insurance coverage and to compare insured and uninsured veterans especially with regard to access to care. Research Design:Data are from the 2001 Minnesota Health Access Survey of a stratified random sample of more than 27,000 respondents, of whom 3,500 were self-identified veterans. Although all veterans were eligible to obtain health care services from the VHA in 2001, veterans not reporting VHA coverage and having no other source of insurance coverage were considered uninsured. Differences in weighted population characteristics are reported. Logistic regression analysis is used to identify factors associated with veterans’ reliance on VHA coverage. Results:Veterans represented 13.4% of the states adult population and 9.3% of the states uninsured nonelderly adult population in 2001. Uninsured veterans were more likely to be single, unemployed, living in rural areas, and reporting constrained access to services than insured veterans. Veterans with a non-VHA source of insurance were less reliant on VHA services. Conclusions:The states uninsurance rate would significantly decrease if VHA capacity constraints were alleviated and veterans relied on the VHA safety net. If veterans’ insurance status matters in states with low uninsurance rates, VHA coverage has broader implications for states with higher veteran concentrations and higher uninsurance rates.

Telehealth by an Interprofessional Team in Patients With CKD: A Randomized Controlled Trial

The Medicare Current Beneficiary Survey (MCBS) is a longitudinal, multipurpose panel survey of a nationally representative sample of Medicare beneficiaries sponsored by the Centers for Medicare and Medicaid Services (CMS). The MCBS serves as a comprehensive data source on self-reported health and socioeconomic status, health insurance, healthcare utilization and costs, and patient satisfaction. CMS uses Medicare claims data to validate self-reported Medicare Fee-For-Service (FFS) utilization. Because the Veterans Health Administration (VHA) does not bill for services, CMS imputes VHA costs. This article addresses the quality of the MCBS dataset for conducting research on Medicare-eligible veterans by addressing the samples representativeness, quality of self-reported data, and accuracy of imputed VHA cost estimates. We compared demographic data from the 1992 and 2001 National Survey of Veterans (NSV) with the MCBS 1992 and 2001 Cost and Use files. We compared self-reported VHA utilization and CMSs imputed costs with VHA administrative datasets. The VHAs Pharmacy Benefits Management (PBM) database is available from fiscal year (FY) 1999 onward, and the VHA Health Economics Resource Centers (HERC) Average Cost datasets are available from FY1998 onward. While the samples were comparable in terms of age, sex, and race, the MCBS respondents were in better health, less likely to be married, and more likely to be widowed than NSV respondents. MCBS underreporting rates were higher for VHA than Medicare outpatient events. Underreporting and differences between CMSs and HERCs costing methodologies contributed to lower MCBS versus VHA administrative person- and event-level costs. Alternatively, average annual VHA prescription costs per capita were higher in the MCBS than in the PBM data. Differences in socioeconomic characteristics of the NSV and MCBS samples may be attributable to differences in sampling methodologies. Higher underreporting rates for VHA versus Medicare FFS outpatient events are likely due to systemic differences between the VHA and private healthcare sectors. While VHA formulary discounts may not be reflected in MCBSs VHA prescriptions costs, lower PBM prescriptions costs are also due to deficient indirect cost data. Since reliable VHA utilization and cost data existed in either FY1998 or FY1999 onward, study goals include estimating the relative share and/or cost of care provided by Medicare and the VHA. Researchers with access to VHA datasets should consider merging them into the MCBS and replacing self-reported utilization and CMSs imputed costs with VHA administrative data. This replacement would significantly improve the accuracy, quality, and usefulness of the MCBS dataset for policy research.
