ABSTRACT: Transradial percutaneous coronary intervention (tPCI) as opposed to the femoral approach (fPCI) is associated with lower rates of bleeding. The purposes of this study were to describe the use of tPCI in the Washington State Clinical Outcomes Assessment Program, identify the predictors of bleeding, and determine whether tPCI was associated with less bleeding in women vs men, age <75 years vs ≥75 years, and baseline creatinine <2.0 mg/dL vs ≥2.0 mg/dL.
This study included 23,599 individuals who had a first tPCI or fPCI performed in 30 centers in Washington State in 2010 and 2011. Data were collected according to specifications from the American College of Cardiology National Cardiovascular Data Registry Cath-PCI version 4.3. The American College of Cardiology National Cardiovascular Data Registry bleeding model was used to calculate adjusted rates.
Transradial percutaneous coronary intervention was used in only 5% of procedures, and in just 3 centers, tPCI was used in >10% of cases. Patient demographics and medical histories were similar in tPCI and fPCI, although the percent of acute cases was higher in fPCI (68% vs 45%, P < .0001). The overall bleeding rate was 2.2%, and the 3 most important predictors of bleeding were acute procedure, women, and age ≥75 years. For women, unadjusted rates of bleeding were 1.4% for tPCI and 4.0% for fPCI (P = .013). Among women, adjusted rates were almost 20% lower for tPCI (3.3% vs 4.1%).
In Washington State, tPCI was used infrequently, although it was associated with lower bleeding rates in high-risk groups including women.

ABSTRACT: BACKGROUND:: Statistical models that identify patients at elevated risk of death or hospitalization have focused on population subsets, such as those with a specific clinical condition or hospitalized patients. Most models have limitations for clinical use. Our objective was to develop models that identified high-risk primary care patients. METHODS:: Using the Primary Care Management Module in the Veterans Health Administration (VHA)'s Corporate Data Warehouse, we identified all patients who were enrolled and assigned to a VHA primary care provider on October 1, 2010. The outcome variable was the occurrence of hospitalization or death during the subsequent 90 days and 1 year. We extracted predictors from 6 categories: sociodemographics, medical conditions, vital signs, prior year use of health services, medications, and laboratory tests and then constructed multinomial logistic regression models to predict outcomes for over 4.6 million patients. RESULTS:: In the predicted 95th risk percentiles, observed 90-day event rates were 19.6%, 6.2%, and 22.6%, respectively, for hospitalization, death, and either hospitalization or death, compared with population averages of 2.7%, 0.7%, and 3.4%, respectively; 1-year event rates were 42.3%, 19.4%, and 51.3%, respectively, compared with population averages of 8.2%, 2.6%, and 10.8%, respectively. The C-statistics for 90-day outcomes were 0.83, 0.86, and 0.81, respectively, for hospitalization, death, and either hospitalization or death and were 0.81, 0.85, and 0.79, respectively, for 1-year outcomes. CONCLUSIONS:: Prediction models using electronic clinical data accurately identified patients with elevated risk for hospitalization or death. This information can enhance the coordination of care for patients with complex clinical conditions.

ABSTRACT: The authors describe characteristics of treatment use among veterans who had addiction treatment in non-Veterans Affairs (VA) facilities in Washington state and who used health care services, including addiction treatment, in VA facilities. From 1996 through 2000, 2,649 VA patients received addiction treatment in Washington state facilities, with 56% (n = 1,489) also receiving some VA specialty addiction treatment and the remaining 44% (n = 1,160) receiving VA health care services unrelated to addiction treatment. Among all veterans receiving addiction treatment in VA facilities in Washington state (n = 11,663), 11% also had treatment in non-VA centers. Over the more than 4-year period, female veterans seen in both systems were less likely to receive VA specialty addiction treatment than were male veterans (40% vs. 58%). This article shows that a significant number of veterans received addiction treatment in both VA and non-VA facilities in Washington state.

ABSTRACT: BACKGROUND: Approximately 2/3 of Veterans admitting to Veterans Health Administration (VHA) facilities present >12 hours after symptom onset of acute myocardial infarction (AMI) ("late presenters"). Veterans admitted to VHA facilities with AMI may delay hospital presentation for different reasons compared to their general population counter parts. Despite the large descriptive literature on factors associated with delayed presentation in the general population, the literature describing these factors among the Veteran AMI population is limited. The purpose of this analysis is to identify predictors of late presentation in the Veteran population presenting with AMI to VHA facilities. Identifying predictors will help inform and target interventions for Veterans at a high risk of late presentation. METHODS: In our cross-sectional study, we analyzed a cohort of 335 male Veterans from nine VHA facilities with physician diagnosed AMI between April 2005 and December 2006. We compared demographics, presentation characteristics, medical history, perceptions of health, and access to health care between early and late presenting Veterans. We used standard descriptive statistics for bivariate comparisons and multivariate logistic regression to identify independent predictors of late presentation. RESULTS: Our cohort was an average of 64 +/- 10.5 years old and was 88% white. Sixty-eight percent of our cohort were late presenters. Bivariate comparisons found that fewer late presenters had attended at least some college or vocational school (late 53.2% vs. early 66%, p = 0.02). Multivariate analysis showed that presentation with ST-elevation myocardial infarction (STEMI) was associated with early presentation (OR = 0.43 95%CI [0.2, 0.9]) and >=2 angina episodes in the prior 24 hours (versus 0-1 episode) was associated with late presentation (OR = 7.5 95%CI [3.6,15.6]). CONCLUSIONS: A significant majority of Veterans presenting to VHA facilities with AMI were late presenters. We found few differences between early and late presenters. Having a STEMI was independently associated with early presentation and reporting >=2 angina episodes in the 24 hours prior to hospital admission was independently associated with late presentation. These independent predictors of early and late presentation are similar to what has been reported for the general population. Despite these similarities to the general population, there may be untapped opportunities for patient education within the VHA to decrease late presentation.

ABSTRACT: Gestational diabetes mellitus (GDM) is a risk factor for type 2 diabetes. Relatively modest weight loss can delay or prevent the onset of type 2 diabetes. The objective of this study was to determine, using a nationally representative survey, whether among women without diabetes, those with a history of GDM (hGDM) were more likely than those without hGDM to be currently attempting weight loss.
This study used data from the 2003 Behavioral Risk Factor Surveillance System, a national, population-based, random-sample telephone survey. Women aged 18 to 44 years without diabetes who answered questions related to current weight loss activity were included in the analysis. The primary outcome was currently attempting weight loss. Logistic regression was used to analyze the association between hGDM and currently attempting weight loss.
We included 53,608 women without diabetes: 1,260 (2%) with hGDM, and 52,348 (98%) without hGDM. Among women with hGDM, 53% were currently attempting weight loss compared with 47% of women without hGDM. Overall, after adjusting for age, race/ethnicity, education, marital status, and medical insurance, compared with women without hGDM, those with hGDM had 20% higher odds of currently attempting weight loss (95% confidence interval [CI], 0.97-1.49); however, among obese women (body mass index ≥ 30 kg/m(2)), compared with women without hGDM, those with hGDM had 46% lower odds of currently attempting weight loss (95% CI, 0.35-0.82).
Obese women with hGDM are less likely to be currently attempting weight loss compared with those without hGDM. Effective interventions for obese women with hGDM are needed.

ABSTRACT: Patients with heart failure (HF) are at high risk of hospitalization or death. The objective of this study was to develop prediction models to identify patients with HF at highest risk for hospitalization or death. Using clinical and administrative databases, we identified 198,460 patients who received care from the Veterans Health Administration and had ≥1 primary or secondary diagnosis of HF that occurred within 1 year before June 1, 2009. We then tracked their outcomes of hospitalization and death during the subsequent 30 days and 1 year. Predictor variables chosen from 6 clinically relevant categories of sociodemographics, medical conditions, vital signs, use of health services, laboratory tests, and medications were used in multinomial regression models to predict outcomes of hospitalization and death. In patients who were in the ≥95th predicted risk percentile, observed event rates of hospitalization or death within 30 days and 1 year were 27% and 80% respectively, compared to population averages of 5% and 31%, respectively. The c-statistics for the 30-day outcomes were 0.82, 0.80, and 0.80 for hospitalization, death, and hospitalization or death, respectively, and 0.82, 0.76, and 0.77, respectively, for 1-year outcomes. In conclusion, prediction models using electronic health records can accurately identify patients who are at highest risk for hospitalization or death. This information can be used to assist care managers in selecting patients for interventions to decrease their risk of hospitalization or death.

ABSTRACT: In anticipation of applying Appropriate Use Criteria for percutaneous coronary intervention (PCI) quality improvement, we determined the prevalence of appropriate, uncertain, and inappropriate PCIs stratified by indication for all PCIs performed in the state of Washington.
Within the Clinical Outcomes Assessment Program, we assigned appropriateness ratings to all PCIs performed in 2010 in accordance with published Appropriate Use Criteria. Of 13 291 PCIs, we successfully mapped the clinical scenario to the Appropriate Use Criteria in 9924 (75%) cases. Of the 3367 PCIs not classified, common failures to map to the criteria included nonacute PCI without prior noninvasive stress results (n = 1906; 57%) and unstable angina without high-risk features (n = 902; 27%). Of mapped PCIs, 8010 (71%) were for acute indications, with 7887 (98%) rated as appropriate, 39 (<1%) as uncertain, and 84 (1%) as inappropriate. Of 1914 mapped nonacute indications, 847 (44%) were rated as appropriate, 748 (39%) as uncertain, and 319 (17%) as inappropriate. Assuming results for noninvasive stress tests when data were missing, in the best-case scenario, 319 (8%) of nonacute PCIs were classified as inappropriate compared with 1459 (38%) in the worst-case scenario. Variation in inappropriate PCIs by facility was greatest for mapped nonacute indications (median = 14%; 25(th) to 75(th) percentiles = 9% to 24%) and nonacute indications with missing data precluding appropriateness classification (median = 54%; 25(th) to 75(th) percentiles = 35% to 66%).
In a complete cohort of PCIs performed in Washington state, 1% of PCIs for acute indications and 17% of PCIs for nonacute indications were classified as inappropriate. Missing data on noninvasive stress tests present a challenge in the application of the criteria for quality improvement.

ABSTRACT: Patients who screen positive for alcohol misuse on the Alcohol Use Disorder Identification Test Consumption Questionnaire (AUDIT-C ≥5 points) have significantly increased postoperative complications. Severe alcohol misuse (AUDIT-C ≥9 points) is associated with increased postoperative health care use; however, little is known about the prevalence of alcohol misuse in demographic and clinical subgroups of surgical patients.
The prevalence of alcohol misuse was evaluated among 10,284 patients (9,771 men and 513 women) who underwent major noncardiac surgery in Veterans Affairs (VA) hospitals during the fiscal years 2004 to 2006 and completed the AUDIT-C. Sex-stratified analyses evaluated prevalence rates of alcohol misuse (AUDIT-C ≥5) and severe misuse (AUDIT-C ≥9) across demographic and clinical subgroups.
Overall, 1,607 (16%) men and 24 (5%) women screened positive for alcohol misuse (AUDIT-C ≥5) in the year before operation, with 4% and 2% screening positive for severe misuse (AUDIT-C ≥9), respectively. Alcohol misuse was more common among men who were <60 years of age, divorced or separated, current smokers, or American Stoke Association class 1 or 2, and those with cirrhosis/hepatitis or substance use disorders. Among patients with alcohol misuse, 36% of men and 58% of women were American Society of Anesthesiologists class 1 or 2, and most did not have diagnoses that were commonly associated with alcohol misuse.
Alcohol misuse is relatively common in male surgical patients. Moreover, surgical patients undergoing operation who screen positive for alcohol misuse are often relatively healthy, without health problems that might alert providers to their alcohol misuse in the absence of screening.

ABSTRACT: Alcohol screening scores ≥5 on the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) up to a year before surgery have been associated with postoperative complications, but the association with postoperative health care use is unknown. This study evaluated whether AUDIT-C scores in the year before surgery were associated with postoperative hospital length of stay, total ICU days, return to the operating room, and hospital readmission.
This cohort study included male Veterans Affairs patients who completed the AUDIT-C on mailed surveys (October 2003 through September 2006) and were hospitalized for nonemergent noncardiac major operations in the following year. Postoperative health care use was evaluated across 4 AUDIT-C risk groups (scores 0, 1 to 4, 5 to 8, and 9 to 12) using linear or logistic regression models adjusted for sociodemographics, smoking status, surgical category, relative value unit, and time from AUDIT-C to surgery. Patients with AUDIT-C scores indicating low-risk drinking (scores 1 to 4) were the referent group.
Adjusted analyses revealed that among eligible surgical patients (n = 5,171), those with the highest AUDIT-C scores (ie, 9 to 12) had longer postoperative hospital length of stay (5.8 [95% CI, 5.0-6.7] vs 5.0 [95% CI, 4.7-5.3] days), more ICU days (4.5 [95% CI, 3.2-5.8] vs 2.8 [95% CI, 2.6-3.1] days), and increased probability of return to the operating room (10% [95% CI, 6-13%] vs 5% [95% CI, 4-6%]) in the 30 days after surgery, but not increased hospital readmission within 30 days postdischarge, relative to the low-risk group.
AUDIT-C screening results could be used to identify patients at risk for increased postoperative health care use who might benefit from preoperative alcohol interventions.

ABSTRACT: High-quality systems have adopted a comprehensive approach to preventive care instead of diagnosis or procedure driven care. The current emphasis on prescribing medications to prevent complications of coronary artery disease (CAD) at discharge following an acute coronary syndrome (ACS) may exclude high-risk patients who are hospitalized with conditions other than ACS.
Among a sample of patients with CAD treated at Veterans Affairs medical centers between January, 2005 and November, 2006, we investigated whether recent non-ACS hospitalization was associated with prescriptions of preventive medications as compared with patients recently hospitalized with ACS.
Of 13,211 patients with CAD, 58% received aspirin, 70% β-blocker, 60% angiotensin-converting enzyme inhibitor (ACE-I) or angiotensin II receptor blocker (ARB), and 65% lipid-lowering therapy. Twenty-five percent of eligible patients were receiving all four medications. Having been hospitalized for a non-ACS event in the prior 6 months did not substantially affect the adjusted proportion on preventive medications. In contrast, among patients hospitalized for ACS in the prior 6 months, the adjusted proportion prescribed aspirin was 21% higher (p < 0.001), β-blocker was 14% higher (p < 0.001), ACE-I or ARB was 9% higher (p < 0.001), lipid therapy was 12% higher (p < 0.001), and prescribed all four medications was 18% higher (p < 0.001) than among patients hospitalized for ACS more than 2 years earlier.
Being hospitalized for a non-ACS condition did not appear to influence preventive medication use among patients with CAD and represents a missed opportunity to improve patient care. The same protocols employed to improve use of preventive medications in patients discharged for ACS might be extended to CAD patients discharged for other conditions as well.

ABSTRACT: Percutaneous coronary intervention (PCI) is used with increasing frequency in patients with diabetes and multivessel disease. This study investigated evolving revascularization strategies in the State of Washington.
The Clinical Outcomes Assessment Program captures all revascularization in the State of Washington and was used to compare diabetic patients with multivessel disease undergoing first-time revascularization from 1999 to 2007. Categorical variables were compared with the chi-squared test and continuous variables were compared with the student's t-test. Results were risk-adjusted using a logistic regression.
A total of 11,602 patients with diabetes and multivessel disease underwent revascularization from 1999 to 2007 and were nearly equally divided between coronary artery bypass grafting (CABG) (51%) and PCI (49%). Patients undergoing CABG had a higher (p < 0.0001) prevalence of congestive heart failure, cerebrovascular disease, peripheral vascular disease, three-vessel coronary artery disease (CAD), and intraaortic balloon pump insertion, but a lower prevalence of female gender, cardiogenic shock, and emergency procedures. Patients undergoing CABG had more (p < 0.0001) three-vessel CAD and more complete revascularization (3.7 vs. 1.5 lesions treated). Short-term risk-adjusted mortality was equivalent. The prevalence of PCI increased from 34.1% in 1999 to 59.4% in 2007.
PCI is applied with increasing frequency to patients with diabetes mellitus (DM) and multivessel disease. PCI is used most commonly in two-vessel CAD or with acute coronary syndromes with more limited and targeted revascularization. CABG is more commonly applied to extensive disease with more complete revascularization. Both the prevalence and percentage of patients undergoing PCI as primary therapy for multivessel disease with DM is increasing. A multidisciplinary approach may be warranted to ensure optimal outcomes.

ABSTRACT: Patients who misuse alcohol are at increased risk for surgical complications. Four weeks of preoperative abstinence decreases the risk of complications, but practical approaches for early preoperative identification of alcohol misuse are needed.
To evaluate whether results of alcohol screening with the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) questionnaire-up to a year before surgery-were associated with the risk of postoperative complications.
This is a cohort study.
Male Veterans Affairs (VA) patients were eligible if they had major noncardiac surgery assessed by the VA's Surgical Quality Improvement Program (VASQIP) in fiscal years 2004-2006, and completed the AUDIT-C alcohol screening questionnaire (0-12 points) on a mailed survey within 1 year before surgery.
One or more postoperative complication(s) within 30 days of surgery based on VASQIP nurse medical record reviews.
Among 9,176 eligible men, 16.3% screened positive for alcohol misuse with AUDIT-C scores ≥ 5, and 7.8% had postoperative complications. Patients with AUDIT-C scores ≥ 5 were at significantly increased risk for postoperative complications, compared to patients who drank less. In analyses adjusted for age, smoking, and days from screening to surgery, the estimated prevalence of postoperative complications increased from 5.6% (95% CI 4.8-6.6%) in patients with AUDIT-C scores 1-4, to 7.9% (6.3-9.7%) in patients with AUDIT-Cs 5-8, 9.7% (6.6-14.1%) in patients with AUDIT-Cs 9-10 and 14.0% (8.9-21.3%) in patients with AUDIT-Cs 11-12. In fully-adjusted analyses that included preoperative covariates potentially in the causal pathway between alcohol misuse and complications, the estimated prevalence of postoperative complications increased significantly from 4.8% (4.1-5.7%) in patients with AUDIT-C scores 1-4, to 6.9% (5.5-8.7%) in patients with AUDIT-Cs 5-8 and 7.5% (5.0-11.3%) among those with AUDIT-Cs 9-10.
AUDIT-C scores of 5 or more up to a year before surgery were associated with increased postoperative complications.

ABSTRACT: The relationship between gastroesophageal reflux disease (GERD) and laryngeal cancer has not been fully elucidated. This case-control study investigates whether GERD increases the odds of developing these malignancies.
Case-control study.
Rates of GERD among cases of laryngeal cancer identified in the Veterans Health Administration outpatient care files (year 2000-2006) were compared with controls. Cases (N = 14,449) were frequency matched 1:1 with controls. Multivariate logistic regression was used to determine the association between GERD and cancer.
After adjusting for tobacco and/or alcohol use, there was no association between GERD and laryngeal cancer (adjusted odds ratio, 1.01; 95% confidence interval, 0.92-1.12, P =.780). Although an association was found when time from GERD diagnosis to malignancy was less than 3 months, it disappeared when this period was extended further.
In this population, there was no increased risk of laryngeal cancer among patients with GERD. However, in subsite analysis, a possible relationship between GERD and glottic cancer was observed. Reverse causality must be considered in future studies assessing the relationship between reflux and laryngeal cancer to limit misclassification bias.

ABSTRACT: The Centers for Medicare and Medicaid Services (CMS) publicly reports hospital-specific risk-standardized, 30-day, all-cause, mortality rates (RSMRs) for all hospitalizations among fee-for-service Medicare beneficiaries for acute myocardial infarction (AMI), heart failure (HF), and pneumonia at non-Federal hospitals.
To examine the performance of the statistical models used by CMS among veterans at least 65 years of age hospitalized for AMI, HF, and pneumonia in Veterans Health Administration (VHA) hospitals.
Cross-sectional analysis of VHA administrative claims data between October 1, 2006 and September 30, 2009.
Thirteen thousand forty-six veterans hospitalized for AMI among 123 VHA hospitals; 26,379 veterans hospitalized for HF among 124 VHA hospitals; and 31,126 veterans hospitalized for pneumonia among 124 VHA hospitals.
Hospital-specific RSMR for AMI, HF, and pneumonia hospitalizations calculated using hierarchical generalized linear models.
Median number of AMI hospitalizations per VHA hospital was 87. Average AMI RSMR was 14.3% [95% confidence interval (CI), 13.9%-14.6%] with modest heterogeneity among VHA hospitals (RSMR range: 8.4%-20.3%). The c-statistic for the AMI RSMR statistical model was 0.79. Median number of HF hospitalizations was 188. Average HF RSMR was 10.1% (95% CI, 9.9%-10.4%) with modest heterogeneity (RSMR range: 6.1%-14.9%). The c-statistic for the HF RSMR statistical model was 0.73. Median number of pneumonia hospitalizations was 221.5. Average pneumonia RSMR was 13.0% (95% CI, 12.7%-13.3%) with modest heterogeneity (RSMR range: 9.0%-18.4%). The c-statistic for the pneumonia RSMR statistical model was 0.72.
The statistical models used by CMS to estimate RSMRs for AMI, HF, and pneumonia hospitalizations at non-Federal hospitals demonstrate similar discrimination when applied to VHA hospitals.

ABSTRACT: Brief alcohol counseling interventions can reduce alcohol consumption and related morbidity among non-dependent risky drinkers, but more intensive alcohol treatment is recommended for persons with alcohol dependence. This study evaluated whether scores on common alcohol screening tests could identify patients likely to have current alcohol dependence so that more appropriate follow-up assessment and/or intervention could be offered. This cross-sectional study used secondary data from 392 male and 927 female adult family medicine outpatients (1993-1994). Likelihood ratios were used to empirically identify and evaluate ranges of scores of the AUDIT, the AUDIT-C, two single-item questions about frequency of binge drinking, and the CAGE questionnaire for detecting DSM-IV past-year alcohol dependence. Based on the prevalence of past-year alcohol dependence in this sample (men: 12.2%; women: 5.8%), zones of the AUDIT and AUDIT-C identified wide variability in the post-screening risk of alcohol dependence in men and women, even among those who screened positive for alcohol misuse. Among men, AUDIT zones 5-10, 11-14 and 15-40 were associated with post-screening probabilities of past-year alcohol dependence ranging from 18 to 87%, and AUDIT-C zones 5-6, 7-9 and 10-12 were associated with probabilities ranging from 22 to 75%. Among women, AUDIT zones 3-4, 5-8, 9-12 and 13-40 were associated with post-screening probabilities of past-year alcohol dependence ranging from 6 to 94%, and AUDIT-C zones 3, 4-6, 7-9 and 10-12 were associated with probabilities ranging from 9 to 88%. AUDIT or AUDIT-C scores could be used to estimate the probability of past-year alcohol dependence among patients who screen positive for alcohol misuse and inform clinical decision-making.

ABSTRACT: Rehabilitation goals following major combat-associated limb loss in World War II and the Vietnam war focused on treatment of the injury and a return to civilian life. The goal for Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) servicemembers is to restore function to the greatest possible degree and, if they desire, return them to Active Duty, by providing them with extensive rehabilitation services and a variety of prosthetic devices. Our study determines the usefulness of these diverse types of prosthetic devices for restoring functional capability and documents prosthesis use and satisfaction. We compare servicemembers and veterans with major combat-associated unilateral lower-limb loss: 178 from the Vietnam war and 172 from OIF/OEF conflicts. Of survey participants with unilateral lower-limb loss, 84% of the Vietnam group and 94% of the OIF/OEF group currently use at least one prosthetic device. Reasons for rejection varied by type of device, but common reasons were pain, prosthesis too heavy, and poor fit. Abandonment is infrequent (11% Vietnam group, 4% OIF/OEF group). Future efforts should aim to improve prosthetic-device design, decrease pain, and improve quality of life for these veterans and servicemembers.

ABSTRACT: Veterans injured in theaters of combat operations are eligible for benefits, including medical care and compensation. This article describes veterans with service-connected disability for major lower- and/or upper-limb loss resulting from combat-field-associated injuries sustained in the Vietnam war, Operation Desert Shield/Operation Desert Storm, and Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF). Using the Department of Veterans Affairs (VA) Compensation and Pension Mini-Master file, we identified 2,690 veterans who in August 2007 received compensation for loss of one or more limbs. More than 97% sustained their injuries in Vietnam; most were young men who served in the U.S. Army or Marine Corps. All but 5% had at least 50% combined service-connected disability and nearly half had a 100% rating. In addition to limb loss, one of the most prevalent compensable conditions was posttraumatic stress disorder, present in 46% of OIF/OEF and 20% of Vietnam veterans. Of these veterans, 82% visited VA outpatient clinics in 2007, although only 4% were hospitalized. A special obligation exists to those who have sustained serious injuries related to combat; this responsibility extends for the life of the servicemember and beyond to his or her spouse and dependents.

ABSTRACT: Care of veterans and servicemembers with major traumatic limb loss from combat theaters is one of the highest priorities of the Department of Veteran Affairs. We achieved a 62% response rate in our Survey for Prosthetic Use from 298 Vietnam war veterans and 283 servicemembers/veterans from Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) who sustained major traumatic limb loss. Participants reported their combat injuries; health status; quality of life; and prosthetic device use, function, rejection, and satisfaction. Despite the serious injuries experienced, health status was rated excellent, very good, or good by 70.7% of Vietnam war and 85.5% of OIF/OEF survey participants. However, many health issues persist for Vietnam war and OIF/OEF survey participants (respectively): phantom limb pain (72.2%/76.0%), chronic back pain (36.2%/42.1%), residual-limb pain (48.3%/62.9%), prosthesis-related skin problems (51.0%/58.0%), hearing loss (47.0%/47.0%), traumatic brain injury (3.4%/33.9%), depression (24.5%/24.0%), and posttraumatic stress disorder (37.6%/58.7%). Prosthetic devices are currently used by 78.2% of Vietnam war and 90.5% of OIF/OEF survey participants to improve function and mobility. On average, the annual rate for prosthetic device receipt is 10.7-fold higher for OIF/OEF than for Vietnam war survey participants. Findings from this cross-conflict survey identify many strengths in prosthetic rehabilitation for those with limb loss and several areas for future attention.

ABSTRACT: Mortality from acute myocardial infarction (AMI) is declining worldwide. We sought to determine if mortality in the Veterans Health Administration (VHA) has also been declining.
We calculated 30-day mortality rates between 2004 and 2006 using data from the VHA External Peer Review Program (EPRP), which entails detailed abstraction of records of all patients with AMI. To compare trends within VHA with other systems of care, we estimated relative mortality rates between 2000 and 2005 for all males 65 years and older with a primary diagnosis of AMI using administrative data from the VHA Patient Treatment File and the Medicare Provider Analysis and Review (MedPAR) files.
Using EPRP data on 11,609 patients, we observed a statistically significant decline in adjusted 30-day mortality following AMI in VHA from 16.3% in 2004 to 13.9% in 2006, a relative decrease of 15% and a decrease in the odds of dying of 10% per year (p = .011). Similar declines were found for in-hospital and 90-day mortality.Based on administrative data on 27,494 VHA patients age 65 years and older and 789,400 Medicare patients, 30-day mortality following AMI declined from 16.0% during 2000-2001 to 15.7% during 2004-June 2005 in VHA and from 16.7% to 15.5% in private sector hospitals. After adjusting for patient characteristics and hospital effects, the overall relative odds of death were similar for VHA and Medicare (odds ratio 1.02, 95% C.I. 0.96-1.08).
Mortality following AMI within VHA has declined significantly since 2003 at a rate that parallels that in Medicare-funded hospitals.
