Partnership between a Veterans Affairs medical center and a podiatric medical college

The health care academic delivery system is dramatically changing in today's economy. In order to survive, the delivery system must decrease its costs and increase productivity. Integration of academic affiliates and community health care facilities has produced a more efficient health care system and improved medical education. The formation and methodology of the mutual benefits and responsibilities between a health care system and a college of podiatric medicine are examined in detail. Developing unique sharing partnerships can mutually improve medical student experiences, reduce financial burdens, combine joint research projects, and ultimately improve patient care.     

Development of a quality improvement checklist for the Department of Veterans Affairs

BACKGROUND: In 1991, the Department of Veterans Affairs developed an instrument to monitor various aspects of quality in Veterans Affairs hospitals. The instrument, the Quality Improvement Checklist, is composed of a series of clinical indicators or questions about administrative or clinical processes, structures, or outcomes. METHOD: For most questions, data are obtained by automated search of electronic patient data-bases maintained in each facility. Individual hospital data are collated and displayed in comparative format with those from other hospitals. Hospitals use the information to identify areas needing further study or improvement. CONCLUSION: Hospital directors and physicians are slowly accepting the usefulness of the instrument.     

Outcome monitoring of fluvastatin in a Department of Veterans Affairs lipid clinic

The aggressive lipid-lowering goals recommended by the second Adult Treatment Panel (ATP II) have created an increasing demand for treatment with 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors. Fluvastatin is the first completely synthetic agent in this class and offers a considerable price advantage over the other HMG-CoA therapies. In May 1994, the Buffalo Veterans Affairs Medical Center Lipid Clinic adopted a fluvastatin-preferred program in which all patients who were recommended for an HMG-CoA reductase inhibitor would be treated with fluvastatin as a first-line agent. Fluvastatin was started at 20 mg daily and titrated to goal. Patients who were stable with other HMG-CoA reductase inhibitors were converted to fluvastatin as just described. Preliminary analysis shows that, for new patients, 20 mg of fluvastatin daily at bedtime reduced low density lipoprotein cholesterol (LDL-C) by an average of 22% (range, 5-32%). Preliminary results for patients converted from another HMG-CoA reductase inhibitor showed that fluvastatin produced an additional LDL-C reduction of 18% (range, 5-30%). With a daily dose of 20 mg fluvastatin, patients with no heart disease (primary prevention) achieved ATP II goals in 60% of cases. For patients with established heart disease (secondary prevention), the goals of ATP II are lower but, despite this, 30% of patients taking fluvastatin at 20 mg daily achieved these goals. The patients in both groups who failed to achieve ATP II goals were titrated to a 40 mg daily dose, but the results of this titration are not yet available. Pharmacoeconomic outcomes were favorable.(ABSTRACT TRUNCATED AT 250 WORDS)     

Change in the Department of Veterans Affairs: what should be done?

Health care in the Department of Veterans Affairs is undergoing the most dramatic change since the era following World War II. The Congress has supported the Undersecretary for Health in his guidance of this change. Traditional hospital-based, specialty-focused care has given way to outpatient and primary care focused health care. Administrative authority has been shifted to 22 Veterans Integrated Service Networks (VISNs). Research goals are being reoriented, and neurology resident allocation is being reduced. VA neurologists and neurology chairs must organize strong service lines in their own VA facilities and in their networks to provide care for veterans with neurologic diseases. VA neurologists must also emphasize their role in principal care and increase their involvement in outcomes research.

Health-related quality of life in patients served by the Department of Veterans Affairs: results from the Veterans Health Study

In a curative resection for advanced sigmoid or rectal cancer, an extensive dissection of the regional lymph nodes is generally required. This often necessitates the removal of the autonomic nerves around the inferior mesenteric artery. The present study was done in an attempt to clarify the influence of a neurectomy around the inferior mesenteric ganglion and plexus on the motility of the colon. In eight dogs, we resected the ganglion and plexus around the inferior mesenteric artery, together with an implantation of strain gauge force transducers in various parts of the colon, and 7-10 days later, colonic motility was examined. The percentage of contractile states and contractile forces increased at both the distal colon in fasting dogs, as well as at the middle colon in the late postprandial period. At the distal colon, contractile forces were noted in the early and late postprandial periods. These contractile abnormalities at the middle and distal colon may thus explain the frequent bowel movements or diarrhea often observed after extensive surgery in patients with sigmoid or rectal cancer.     

Female veterans' use of Department of Veterans Affairs health care services

OBJECTIVES: As access of women to mental health services has become increasingly important, empirical research has begun to examine the determinants of mental health care utilization across gender. This article examines the effect of being an extreme minority on utilization of Department of Veterans Affairs (VA) health services by female veterans. METHODS: Data were collected on a representative national sample of veterans in 1992 as part of the National Survey of Veterans. These data included information on sociodemographic variables, military service variables, physical health and disability, and health services utilization. The authors examined whether women who used health services in 1992, and who were eligible for VA care, differed from men on the likelihood of using any VA health services and on the likelihood of use of VA outpatient and inpatient health services. In addition, we compared VA health care utilization among subgroups of veterans with physical and mental disorders, and compared self-reported reasons for choice of health care provider, across gender. RESULTS: Results indicated that female veterans were less likely than male veterans to use VA health services. This difference was explained by lower utilization by women of VA outpatient services, since inpatient admission rates were the same across gender. The lower outpatient utilization was specific to women with self-reported mental disorders. Women with physical conditions did not differ from men with similar conditions in their VA outpatient utilization. Finally, men and women did not differ on their reasons for choosing VA or non-VA care. CONCLUSIONS: The authors conclude that extreme gender minority status appears to affect outpatient utilization rates at the VA among women with mental disorders, perhaps because of the more personal or sensitive nature of the services involved. Further research is needed to understand why certain women may be underutilizing VA outpatient services and on the consequences of minority gender status for health service utilization, more generally.     

Reenvisioning internship training in clinical and counseling psychology: Developments in the Department of Veterans Affairs system.

The Department of Veterans Affairs (VA) system has been a major source of funded, American Psychological Association-accredited psychology internships. The VA system has also been a leader in innovations in internship training. Currently, VA is in the process of redefining the system for allocating funds for psychology internship training, along with funding for all associated health professions. The history and process of that planning are reviewed in this article, along with the current status of plans for the reallocation process. The new system will specifically emphasize training in areas of high clinical priority for VA, particularly primary care, mental health, rehabilitation, and geriatric settings. The new system also will put major emphasis on training in interprofessional settings and training to work effectively as an interprofessional team member.

The SAFE Program: A family psychoeducational curriculum developed in a Veterans Affairs medical center.

One of the unintended positive consequences of deinstitutionalization and managed care restrictions has been an increased awareness of the impact of serious mental illness on the family. The Support and Family Education (SAFE) Program: Mental Health Facts for Families is a 14-session curriculum of monthly workshops for caregivers. In contrast to similar programs, the SAFE Program is facilitated by mental health professionals, is not diagnostic specific, and includes attention to posttraumatic stress disorder. Three years of outcome data reveal that program attendance is related to increased understanding of mental illness and enhanced awareness of Veterans Affairs resources. Workshop attendance is positively correlated with improvements in participants' self-care. The entire SAFE Program manual is available free of charge on the Internet (http://w3.ouhsc.edu/safeprogram). (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Counseling psychology in Veterans Affairs medical centers: Perceptions of chiefs of psychology.

Counseling psychology (CP) has attempted to define itself in ways that accurately reflect the specialty, that do not limit its practitioners from working in their domains of competence, and that set it apart from clinical psychology. S. Cleveland (1980) considered the success of this self-definition in a survey on the perception of counseling psychologists by chiefs of psychology services in the Veterans Administration medical centers (VAMCs). He suggested that counseling psychologists were "defecting" to clinical positions in the VAMCs and that some negative bias existed toward CP by some VAMC chiefs. This survey attempts to determine whether the chiefs' attitudes have shifted as CP redefines itself. Results were similar to those found by Cleveland: Negative bias exists but has decreased. In addition, counseling psychologists in the VAMCs have found a variety of positions, expanding their role beyond previous narrow definitions.

Utility of psychophysiological measurement in the diagnosis of posttraumatic stress disorder: results from a Department of Veterans Affairs Cooperative Study

OBJECTIVE: Predicting postrepair right ventricular/left ventricular pressure ratio has prognostic relevance for patients undergoing total repair of pulmonary atresia, ventricular septal defect, and major aortopulmonary collateral arteries. To this purpose, we currently rely on 2 novel parameters: (1) preoperative total neopulmonary arterial index and (2) mean pulmonary artery pressure changes during an intraoperative flow study. METHODS: Since January 1994, 15 consecutive patients (aged 64 +/- 54 months) with pulmonary atresia, ventricular septal defect, and major aortopulmonary collaterals were managed according to total neopulmonary arterial index. Seven patients with hypoplastic pulmonary arteries and a total neopulmonary arterial index less than 150 mm(2)/m(2) underwent palliative right ventricular outflow tract reconstruction followed by secondary 1-stage unifocalization and ventricular septal defect closure. The other 8 patients with a preoperative index of more than 150 mm(2)/m(2) underwent primary single-stage unifocalization and repair. The ventricular septal defect was closed in all cases (reopened in 1). In 9, such decision was based on an intraoperative flow study. RESULTS: Patients treated by right ventricular outflow tract reconstruction had a significant increase of pulmonary artery index (P=.006) within 22 +/- 6 months. Repair was successful in 14 cases (postrepair right ventricular/left ventricular pressure ratio = 0.47 +/- 0.1). One hospital death occurred as a result of pulmonary vascular obstructive disease, despite a reassuring intraoperative flow study. Accuracy of this test in predicting the postrepair mean pulmonary artery pressure was 89% (95% CI: 51%-99%). At follow-up (18 +/- 12 months), all patients are free of symptoms, requiring no medications. CONCLUSIONS: The integrated approach to total repair of pulmonary atresia, ventricular septal defect, and major aortopulmonary collaterals by preoperative calculation of total neopulmonary arterial index, right ventricular outflow tract reconstruction (when required), and intraoperative flow study may lead to optimal intermediate results.     

Treatment of Department of Veterans Affairs primary care patients with posttraumatic stress disorder.

Posttraumatic stress disorder (PTSD) is common among Veterans Affairs (VA) primary care patients and may be managed via multiple treatment pathways. Using the Behavioral Model of Health Service Use (Anderson, 1995), this retrospective study based on medical chart review examined factors associated with three types of mental health treatment: intervention by a 1) primary care provider (PCP), 2) primary care-mental health integration (PC-MHI) provider, and 3) specialty mental health (SMH) provider. A second goal was to describe PTSD treatment services for patients not receiving SMH by detailing the content of mental health treatment provided by PCPs and PC-MHI providers. Electronic medical record data for a five year time period for 133 Veterans were randomly selected for review from a population 6,637 primary care patients with PTSD. Results indicated that the evaluated needs of participants (i.e., number of unique medical and psychiatric disorders) were associated with Veterans receiving more intensive services (i.e., SMH). PCPs commonly addressed patients' mental health concerns, but patients often declined referrals for mental health treatment. PC-MHI consultations most often focused on medication management and supportive psychotherapy. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Outcomes of acute myocardial infarction in the Department of Veterans Affairs: does regionalization of health care work?

The regulation of the Escherichia coli secA gene, whose translation is auto-repressed except when protein secretion becomes limiting, was investigated using a combination of genetic and biochemical approaches. Oligonucleotide-directed deletion and point mutagenesis was used to show that only the last quarter of the upstream gene, geneX, and the geneX-secA intergenic are essential for proper regulation. This region previously shown to contain a secretion-responsive element contains two predicted helices, helix I and II, the latter of which would occlude the secA Shine-Dalgarno sequence. Mutations that destabilized the lower portion of helix II increased secA basal expression, reduced auto-repression by SecA protein, but retained a normal pattern of derepression of secA expression during a protein export block. The introduction of compensatory mutations into helix II that were predicted to restore base-pairing restored secA regulation to wild-type levels or nearly so, suggesting that this helix does play a role in secA auto-regulation in vivo. In contrast, mutations in the lower portion of helix I decreased secA basal expression, reduced auto-repression by SecA protein, and abolished the responsiveness of secA expression to a protein export block. In this latter case introduction of compensatory mutations into helix I that were predicted to restore base-pairing did not restore proper secA regulation, indicating that specific nucleotides in this region are required for normal secA regulation. Primer-extension inhibition (toeprint) analysis with 30 S ribosoma subunits, tRNAMet, and a model segment of geneX-secA RNA carrying the relevant mutations was used to show that mutations that destabilized helix II increased ribosome binding at the secA translation initiation site, while mutations that perturbed helix I decreased ribosome binding at this site. Our results suggest strongly that there is a system of dual regulation of secA translation, whereby helix I serves as an activator element while helix II serves as a repressor element.     

Variation in utilization of cardiac procedures in the Department of Veterans Affairs health care system: effect of race

OBJECTIVES: Utilization rates for cardiac catheterization and cardiac surgery in the Department of Veterans Affairs (VA) health care system were studied to determine whether racial differences existed in a delivery plan in which access is not determined by patient finances. BACKGROUND: Prior studies have demonstrated significant differences in utilization of cardiac diagnostic and therapeutic resources by white and black patients. Reasons for the reduced utilization by black patients include socioeconomic, biologic and sociocultural effects. METHODS: Computerized discharge records of 30,300 patients with coronary artery disease and 1,335 patients with valvular heart disease who were discharged from any of 172 VA Medical Centers between October 1, 1990 and September 30, 1991 were studied. RESULTS: For patients with coronary artery disease, utilization rates of cardiac catheterization were significantly greater for white patients (503.4 procedures/1,000 patients) than for black patients (433.2/1,000 patients), with a relative odds ratio of 1.33. Rates for surgery (179.0 vs. 124.5/1,000 patients) were also greater for whites than for blacks, with a relative odds ratio of 1.53. For the subset with valve disease, the catheterization rate was significantly greater for whites than for blacks (575.4 vs. 432.6 procedures/1,000 patients), with a relative odds ratio of 1.78. Surgical rates were not significantly different (423.8 vs. 354.6 operations/1,000 patients). Racial differences for both catheterization and surgery varied widely as a function of geographic region and the level of complexity of the local VA facility. CONCLUSIONS: Racial differences in resource utilization exist in a health care system in which economic influences are minimized. The pattern of these differences depends on numerous variables and suggests both biologic and sociocultural factors as underlying causes.     

Antihypertensive efficacy of treatment regimens used in Veterans Administration hypertension clinics. Department of Veterans Affairs Cooperative Study Group on Antihypertensive Agents

There is continuing uncertainty about whether morbidity and mortality of treated hypertensive patients depends on the drug(s) used to treat or only on the level of blood pressure achieved. This study was undertaken in a sample of special Veterans Administration hypertension clinics to determine which antihypertensive drugs were selected by the involved healthcare providers and how effective they were in achieving normotension. Hypertensive veterans (n = 6100) were followed in six VA Hypertension Screening and Treatment Program clinics for 46 months beginning in May 1989. Their average age was 60.7 years; 53% lived in the Stroke Belt; 46% had target organ damage, 36% were black, 23% smoked, and 10% had diabetes mellitus. Antihypertensive regimens were divided into 12 all-inclusive categories. Blood pressures were averaged at the last study visit for all patients on a regimen. The regimens of diuretic or diuretic plus beta-blocker gave the lowest average pressures (140.6/82.3 mm Hg) and calcium antagonist the highest (149.0/86.5 mm Hg). ANOVA indicated that differences between seven common regimens and also between the four single drug regimens were highly significant (P<.0001). This pattern of low treated pressure with the "old" agents and higher treated pressure with newer agents was reflected in the percentage of patients controlled below 140/90 mm Hg and the percentage uncontrolled above 159/94 mm Hg. Blacks and patients with target organ damage resembled the entire cohort in average treated diastolic blood pressure, but the former had lower and the latter had higher treated systolic blood pressure than the entire cohort.     

Percutaneous transluminal coronary angioplasty versus medical therapy for stable angina pectoris: outcomes for patients with double-vessel versus single-vessel coronary artery disease in a Veterans Affairs Cooperative randomized trial. Veterans Affairs ACME InvestigatorS

OBJECTIVES: This study sought to assess outcomes of men with double-vessel coronary artery disease randomly assigned to treatment by percutaneous transluminal coronary angioplasty (PTCA) or medical therapy, compared with previously reported outcomes for men with single-vessel disease. BACKGROUND: We previously reported that PTCA provides better symptom relief and treadmill performance than medical therapy for men with stable angina pectoris due to single-vessel disease. Whether this advantage applies to patients with double-vessel disease is unknown. METHODS: Male patients (n = 328) with stable angina pectoris and ischemia on treadmill testing were randomly assigned to PTCA or medical therapy; 101 patients had double-vessel disease, and 227 had single-vessel disease. Symptoms, treadmill performance, quality of life score, coronary stenosis and myocardial perfusion were compared at baseline and at 6 months. Patients were followed up for up to 6 years and underwent additional treadmill testing 2 to 3 years after randomization. RESULTS: PTCA-treated and medically treated patients with double-vessel disease experienced comparable improvement in exercise duration (+1.2 vs. +1.3 min, respectively, p = 0.89), freedom from angina (53% and 36%, respectively, p = 0.09) and improvement of overall quality of life score (+1.3 vs. +4.4, respectively, p = 0.32) at 6 months compared with baseline. This contrasts with greater advantages favoring PTCA by these criteria in patients with single-vessel disease (p = 0.0001 to 0.02). Trends present at 6 months persisted at late follow-up. Patients undergoing double-vessel dilation had less complete initial revascularization (45% vs. 83%) and greater average stenosis of worst lesions at 6 months (74% vs. 56%). Likewise, patients with double-vessel disease showed less improved myocardial perfusion imaging (59% vs. 75%). CONCLUSIONS: PTCA is beneficial in male patients with double-vessel disease; however, we cannot demonstrate the same advantage over medical therapy seen in similar patients with single-vessel disease. Less complete revascularization and greater restenosis for patients having multiple dilations would account for these findings. Alternatively, a type 2 error might be operative. Technical advances since completion of this trial might improve these outcomes. These findings warrant further investigation in a larger trial.     

Impact of race and age on the effects of regionalization of cardiac procedures in the Department of Veterans Affairs Health Care System

Previous studies have demonstrated that regionalization of resources for cardiac catheterization, percutaneous coronary artery angioplasty (PTCA), and coronary artery bypass graft surgery (CABG) reduces the rate of procedure use. It was hypothesized that the impact of regionalization would be greater for the elderly and for African-Americans than for other populations. Discharge medical records of 30,901 patients admitted to a Veterans Affairs (VA) medical center between October 1, 1993, and September 30, 1994, with a diagnosis of coronary artery disease were analyzed. The presence of a cardiac catheterization laboratory in the patients' local VA facility significantly increased the likelihood of undergoing catheterization, PTCA, and CABG, as determined by odds ratios and associated confidence limits estimated by logistic regression techniques. The presence of a cardiac surgical facility also significantly increased the likelihood of having the procedures. The odds ratios estimating the effects of resource availability were significantly greater for the subgroup of patients aged > or =70 years than for the younger subgroup for catheterization, PTCA, and CABG and for African-Americans than for white patients for PTCA and CABG. Thus, within the VA health care system, regionalization of cardiac procedures has a significant impact on utilization rates of tertiary cardiac procedures. These differences are significantly greater for the elderly and for African-Americans than for the general population.
