Patient satisfaction and use of Veterans Affairs versus non-Veterans Affairs healthcare services by veterans.

OBJECTIVES: Chronically ill patients who are not satisfied with their care may change healthcare providers or systems, which could disrupt continuity of care and impede management of their conditions. We examined whether patient satisfaction affected subsequent use of non-Veterans Affairs (VA) services among chronically ill veterans discharged from VA hospitals. METHODS: The data used in this study came from a multicenter trial of increased access to primary care. We enrolled patients with diabetes, heart failure, and/or chronic obstructive pulmonary disease who were discharged from 1 of 9 VA medical centers. At baseline, we assessed satisfaction using the Patient Satisfaction Questionnaire. VA and non-VA utilization over the subsequent 6 months were assessed using VA and Medicare administrative data, non-VA billing data, and patient interviews. Using multivariable logistic regression analyses, we examined whether baseline patient satisfaction was associated with non-VA inpatient or outpatient utilization during the next 6 months. We conducted the same analysis for Medicare-eligible veterans, a group with better access to non-VA care. RESULTS: Of 1375 study patients, 174 (13%) used non-VA healthcare. Patients with non-VA utilization were older and lived farther from a VA. The odds of non-VA use decreased by 11% as satisfaction increased (odds ratio 0.89; 95% confidence interval 0.83-0.97; P = 0.005). This relationship was strongest among Medicare-eligible veterans (odds ratio 0.85; 95% confidence interval 0.77-0.93; P = 0.001). CONCLUSIONS: Dissatisfied veterans discharged from the hospital were more likely to go outside VA for care. Thus, improvements in patient satisfaction may lead to improvements in continuity of care.

Outcomes after acute coronary syndrome admission to primary versus tertiary Veterans Affairs medical centers: the Veterans Affairs Access to Cardiology study.

BACKGROUND: There is a concern that patients with acute coronary syndrome (ACS) admitted to primary care hospitals (without on-site cardiac procedures) may be at risk for worse outcomes compared with patients admitted to tertiary care hospitals. In addition to mortality, one way to assess patient outcomes is via health status and rehospitalization rates. We compared the health status and rehospitalization of patients with ACS admitted to primary versus tertiary care Veterans Affairs hospitals. METHODS: This was a cohort study of 2132 patients with ACS admitted to 21 Veterans Affairs hospitals (12 primary care and 9 tertiary care) from 1998 to 1999. Primary outcomes were 7-month health status as measured by the Seattle Angina Questionnaire and rehospitalization. Hierarchical multivariable regression was used to evaluate the association between admission to a primary (vs tertiary) care hospital and these outcomes. Discharge medications and 7-month cardiac procedure rates were also compared. RESULTS: There were no significant differences in discharge medication rates between primary and tertiary hospital patients. Forty-two percent of the patients admitted to a primary care hospital was transferred to a tertiary care hospital during index admission. Primary hospital patients had significantly lower 7-month rates of cardiac catheterization (36% vs 51%, P < .001) and percutaneous coronary intervention (11% vs 20%, P < .001), but there were no differences in coronary artery bypass graft surgery rates. After risk adjustment, there were no significant differences in 7-month angina frequency (odds ratio [OR] 0.98, 95% CI 0.78-1.22), physical limitation (OR 0.97, 95% CI 0.77-1.23), quality of life (OR 1.12, 95% CI 0.89-1.40), or rehospitalization (OR 1.07, 95% CI 0.54-2.14) between the 2 groups. CONCLUSIONS: These results suggest that an integrated health care system can achieve similar intermediate-term health status and rehospitalization outcomes for patients with ACS irrespective of the site of admission despite the lower rates of cardiac procedures for the primary care hospital patients.

Inpatient rehabilitation after stroke: a comparison of lengths of stay and outcomes in the Veterans Affairs and non-Veterans Affairs health care system.

BACKGROUND: Patients have longer lengths of hospital stay (LOS) in VA medical centers than in the general health care system. OBJECTIVE: The objective of this study was to determine whether resource use and outcome differences between VA and non-VA inpatient rehabilitation facilities remain after controlling for patient and medical care delivery differences. DESIGN: This analysis involved 60 VA inpatient rehabilitation units and 467 non-VA rehabilitation hospitals and units. Multivariate adjusted resource use and patient outcome differences were compared across setting within patients grouped by severity of disability at admission through assignment to the Function Related Group (FRG) patient classification system. SUBJECTS: The study included 55,438 stroke patients. MEASURES: Study measures were LOS, functional status at discharge, and community discharge. RESULTS: The VA serves a higher proportion of patients who are single, separated, or divorced; are unemployed or retired as a result of disability, and are not white (P < 0.0001). These traits tended to be associated with longer LOS, lower functional outcomes, and reduced rates of community discharge. After adjusting for these and other differences, depending on FRG, average LOS remained from 30% to 200% longer in the VA centers (P < 0.05); average functional outcomes were significantly higher in 8 and lower in 2 FRGs (P < 0.05); and community discharge rates were lower in 12 FRGs (P < 0.05). CONCLUSIONS: While certain variables accounted for some of the observed differences in resource use and outcomes, differences remained after adjustment. Fewer incentives for cost containment and less support in patients' home environments may be among the most important unmeasured determinants of VA differences.

Utilization of laparoscopic antireflux surgery at a single Veterans Affairs facility compared with the Veterans Affairs national trend.

BACKGROUND: The widespread use of laparoscopy in the early 1990s has led to an increase in the utilization of antireflux procedures for the treatment of gastroesophageal reflux disease (GERD). This trend has been observed in the private sector, but not within the Department of Veterans Affairs (VA) health care system. Published data suggest that among patients undergoing antireflux surgical procedures, those in the VA were less likely than those in the private sector to undergo laparoscopic surgery. The objective of this study was to determine the trend in the use of laparoscopic antireflux surgical procedures at our VA facility and compare it with the national VA trend. METHODS: All antireflux operations performed at our VA facility from 1991 to 2002 were recorded along with techniques used. National VA data on the utilization of antireflux procedures from 1991 to 1999 was extracted from a recent publication by Finlayson et al. RESULTS: In contrast to the trend observed nationally across VA hospitals, the rate of utilization of antireflux surgery at our VA facility has increased compared with baseline in 1991. Of 83 fundoplications performed from 1991 to 2002, 76 (92%) were attempted or completed laparoscopically. The conversion rate from laparoscopic to open approach was 6.6%. CONCLUSIONS: We have observed an increase in the utilization of antireflux surgery since 1991 at our VA facility. In addition, most fundoplications were performed laparoscopically. These findings are in contrast to published national VA data. The presence of surgeons with interest in laparoscopy, institutional support, and a dedicated esophageal function laboratory may explain these findings.

Lessons from combination therapy in Veterans Affairs Studies. Department of Veterans Affairs Cooperative Study Group on antihypertensive agents.

A subset of 102 patients of an original cohort of 1292 with stage 1 to 2 hypertension was characterized by having failed to achieve goal blood pressure (< 90 mm Hg diastolic) after treatment with two single antihypertensive drugs. These patients were given a combination of the two drugs on which they had failed to achieve blood pressure goal when they were administered as single-drug therapy. The drugs were hydrochlorothiazide, atenolol, captopril, diltiazem-SR, clonidine, and prazosin. We examined the responses in each of the drug combination categories by the order that the drugs were administered, by estimated total response rates for the combinations, and by age and race. The order of drug administration did have an effect for some of the drug pairs. This was of two types: 1) different results for each member of the pair, but the same combination result; and 2) different end result of the combination. An example of the first type is that prazosin had only a 6% response rate in patients who had failed on diltiazem, while diltiazem had a 22% response rate in patients who had failed on prazosin. Nevertheless, the combinations yielded the same total responses (86% and 84%) regardless of order. An example of the second type is that captopril-diltiazem was less effective in total response than diltiazem-captopril (88% v 97%). Differences were seen in the response to combinations in the race and age groups. There were ordering differences of type similar to those described above. We conclude that combination drug therapy is highly effective even when the individual components have failed and that some differences in response by order of drug administration may occur.

Cardiovascular events and correlates in the Veterans Affairs Diabetes Feasibility Trial. Veterans Affairs Cooperative Study on Glycemic Control and Complications in Type II Diabetes.

BACKGROUND: The risks and benefits of intensive therapy in non-insulin-dependent diabetes mellitus (NIDDM) need to be defined. In preparation for a long-term trial, a feasibility study of 153 men in 5 medical centers compared standard vs intensive insulin therapy. OBJECTIVE: To assess the rate of development of new cardiovascular events and their correlates. METHODS: Patients with a mean +/- SD age of 60 +/- 6 years and diagnosis of NIDDM for 7.8 +/- 4.0 years were randomly assigned to a standard (1 insulin injection every morning) or to an intensive treatment arm (stepped plan from 1 evening injection of insulin, alone or with glipizide, to multiple daily injections) designed to attain near-normal glycemia levels. A 2.07% separation of glycosylated hemoglobin (HbA1c) was sustained for a mean follow-up of 27 months (P < .001). Predefined cardiovascular events were assessed by a committee unaware of treatment assignment. RESULTS: Mild and moderate hypoglycemic events were more frequent in the intensive than in the standard treatment arm (16.5 vs 1.5 per patient per year, respectively). Mean insulin dose was 23% lower in the standard treatment arm (P < .001). There were 61 new cardiovascular events in 24 patients (32%) in the intensive treatment arm and in 16 patients (20%) in the standard treatment arm (P = .10). There was no difference in total and cardiovascular mortality (n = 5 and n = 3 in the intensive and standard treatment arms, respectively) or in new events in patients with cardiovascular history (n = 10 in each arm). In Cox regression analysis, the only significant correlate for new cardiovascular events was previous cardiovascular disease (P = .04). Entering in the analysis any baseline cardiovascular abnormality, the regression model indicated a lower HbA1c level prior to the event as the only correlate for new cardiovascular events (P = .05). CONCLUSION: A long-term prospective trial is needed to assess the risk-benefit ratio of intensive insulin therapy for NIDDM in patients who require it.

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.

Mental disorders and mental health treatment among U.S. Department of Veterans Affairs outpatients: the Veterans Health Study.

OBJECTIVE: The authors examined the self-reported presence and treatment of current depressive disorder, posttraumatic stress disorder (PTSD), and alcohol-related disorder in a group of outpatient veterans. METHOD: Data were obtained from the Veterans Health Study, a longitudinal investigation of male veterans' health. A representative sample of 2,160 outpatients (mean age = 62 years) was drawn from Boston-area U.S. Department of Veterans Affairs (VA) outpatient facilities. The participants completed screening measures for depression, PTSD, and alcohol-related disorder. Mental health treatment was assessed by interviews. RESULTS: The screening criteria for at least one current mental disorder were satisfied by 40% (N = 856) of the patients. Screening rates were 31% (N = 676) for depression, 20% (N = 426) for PTSD, and 12% (N = 264) for alcohol-related disorder. Patients who screened positively for current mental disorders were younger, less likely to be married or employed, and more likely to report traumatic exposure than were those without mental disorders. Of those who met the screening criteria for any of the targeted mental disorders, 68% (N = 579) reported receiving mental health treatment. Younger, Caucasian men and those who reported more traumatic exposure were more likely to report receiving mental health treatment than were others who screened positively for mental disorders. CONCLUSIONS: Screening rates of depression and PTSD and rates of mental health treatment were considerably higher among these VA outpatients than among similar patients in primary care in the private sector. Although the VA is currently meeting the mental health care needs of its patients, future fiscal constraints could affect most adversely the treatment of non-Caucasian and older patients and those with a history of traumatic exposure.

Treatment of hypertension in the elderly. III. Response of isolated systolic hypertension to various doses of hydrochlorothiazide: results of a Department of Veterans Affairs cooperative study. Department of Veterans Affairs Cooperative Study Group on Antihypertensive Agents.

In a double-blind randomized study, we evaluated the effects of 25 mg vs 50 mg of hydrochlorothiazide in 51 elderly patients (aged 68.9 +/- 7.0 years) with isolated systolic hypertension (blood pressure, 160 to 239 mm Hg systolic and less than 90 mm Hg diastolic). Dose levels could be increased to twice daily to control blood pressure. The reductions in blood pressure (25.4/6.8 mm Hg and 28.9/7.4 mm Hg) and proportion of patients in whom blood pressure was controlled (78% and 89%) were similar in the lower- and higher-dose groups during the titration phase. However, serum potassium level was reduced more in the higher-dosage (0.57 mmol/L) than the lower-dosage (0.17 mmol/L) group. There were no significant changes in blood pressure during a 24-week maintenance phase. No patient required withdrawal from the study because of adverse effects, and cognitive-behavioral function was well preserved. We conclude that hydrochlorothiazide is effective and well tolerated in older patients with isolated systolic hypertension, many of whom may be effectively treated with 25 mg of hydrochlorothiazide once daily.

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

BACKGROUND: The Department of Veterans Affairs Health Care System (VA) is the largest integrated single payer system in the United States. To date, there has been no systematic measurement of health status in the VA. The Veterans Health Study has developed methods to assess patient-based health status in ambulatory populations. OBJECTIVES: To describe the health status of veterans and examine the relationships between their health-related quality of life, age, comorbidity, and socioeconomic and service-connected disability status. METHODS: Participants in the Veterans Health Study, a 2-year longitudinal study, were recruited from a representative sample of patients receiving ambulatory care at 4 VA facilities in the New England region. The Veterans Health Study patients received questionnaires of health status, including the Medical Outcomes Study Short Form 36-Item Health Survey; and a health examination, clinical assessments, and medical history taking. Sixteen hundred sixty-seven patients for whom we conducted baseline assessments are described. RESULTS: The VA outpatients had poor health status scores across all measures of the Medical Outcomes Study Short Form 36-Item Health Survey compared with scores in non-VA populations (at least 50% of 1 SD worse). Striking differences also were found with the sample stratified by age group (20-49 years, 50-64 years, and 65-90 years). For 7 of the 8 scales (role limitations due to physical problems, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health), scores were considerably lower among the younger patients; for the eighth scale (physical function), scores of the young veterans (aged 20-49 years) were almost comparable with the levels in the old veterans (>65 years). The mental health scores of young veterans were substantially worse than all other age groups (P<.001) and scores of screening measures for depression were significantly higher in the youngest age group (51%) compared with the oldest age groups (33% and 16%) (P<.001). CONCLUSIONS: The VA outpatients have substantially worse health status than non-VA populations. Mental health differences between the young and old veterans who use the VA health care system are sharply contrasting; the young veterans are sicker, suggesting substantially higher resource needs. Mental health differences may explain much of the worse health-related quality of life in young veterans. As health care systems continue to undergo a radical transformation, the Department of Veterans Affairs should focus on the provision of mental health services for its younger veteran.

Accessibility and acceptability of the Department of Veteran Affairs health care: diverse veterans' perspectives.

OBJECTIVES: Diverse veteran's perspectives on the accessibility and acceptability of the Department of Veteran Affairs (VA) health services are presented. METHODS: The qualitative methodology uses 16 focus groups (N = 178) stratified by war cohort (World War II and Korean Conflict versus Vietnam War and Persian Gulf War) and four ethnic/racial categories (African American, Asian American, European American, Hispanic American). RESULTS: Five themes emerged regarding veterans' health care expectations: (1) better information regarding available services, (2) sense of deserved benefits, (3) concern about welfare stigma, (4) importance of physician attentiveness, and (5) staff respect for patients as veterans. Although veterans' ethnic/racial backgrounds differentiated their military experiences, it was the informants' veteran identity that framed what they expected of VA health services. CONCLUSIONS: Accessibility and acceptability of VA health care is related to veterans' perspectives of the nature of their entitlement to service. Provider education and customer service strategies should consider the identified factors to increase access to VA as well as improve veterans' acceptance of the care.

Characteristics of ambulatory care clinics and pharmacists in Veterans Affairs medical centers. IMPROVE investigators. Impact of Managed Pharmaceutical Care on Resource Utilization and Outcomes in Veterans Affairs Medical Centers.

The type and extent of ambulatory care clinical pharmaceutical services in selected Veterans Affairs medical centers (VAMCs) were studied as part of a larger project. Questionnaires were sent to the 174 VAMCs to determine the extent of clinical pharmacy activity in ambulatory care clinics, characteristics of outpatient pharmacies and clinics, and characteristics of ambulatory care pharmacists in VAMCs and to identify sites for the IMPROVE (Impact of Managed Pharmaceutical Care on Resource Utilization and Outcomes in Veterans Affairs Medical Centers) project. Fifty VAMCs responded to the survey. There were 512 ambulatory care clinics within these VAMCs. There was some pharmacist coverage in 75% of the clinics. The highest pharmacist coverage was in walk-in refill, therapeutic drug monitoring, and anticoagulation clinics. Clinical pharmacists at 68% of the VAMCs had prescribing privileges in ambulatory care clinics. Clinical pharmacists managed 29.9% of the clinics. The types of clinics most commonly managed by pharmacists were therapeutic drug monitoring, anticoagulation, walk-in refill, and lipid clinics. Nurse practitioners or physician assistants also were providing primary care in 41% of the clinics. There were 242 ambulatory care clinical pharmacy specialists practicing in the 50 VAMCs. Of these, 41.3% had three years or less of ambulatory care experience. Most pharmacists were in the clinic five days per week. A Pharm.D. degree was the highest degree obtained for 76.9%. Ambulatory care pharmaceutical services are common in VAMCs and are being provided by numerous clinical pharmacists.

Predicting costs of Veterans Affairs health care in Gulf War veterans with medically unexplained physical symptoms.

Measures of post-traumatic stress disorder (PTSD) and depression were used to predict Veterans Affairs outpatient treatment costs among Persian Gulf War veterans with medically unexplained physical symptoms. Patients (N = 206) enrolled in a Veterans Affairs primary care clinic for Persian Gulf War veterans completed study assessments at the initial appointment or at a proximal follow-up visit. Costs of care for mental health, medical, and pharmacy services for these veterans were computed for the subsequent 6-month period. Depression and PTSD symptoms explained a significant share of variance in costs of mental health care and pharmacy services, after adjustment for covariates. None of the mental status measures was significantly related to costs of medical care. Models using global measures of mental health status were as robust as models using disorder-specific measures of PTSD and depression in predicting mental health care and pharmacy costs. The implications of these findings for anticipating costs of care for Persian Gulf War veterans are discussed.

Measurement in Veterans Affairs Health Services Research: veterans as a special population.

OBJECTIVE: To introduce this supplemental issue on measurement within health services research by using the population of U.S. veterans as an illustrative example of population and system influences on measurement quality. PRINCIPAL FINDINGS: Measurement quality may be affected by differences in demographic characteristics, illness burden, psychological health, cultural identity, or health care setting. The U.S. veteran population and the VA health system represent a microcosm in which a broad range of measurement issues can be assessed. CONCLUSIONS: Measurement is the foundation on which health decisions are made. Poor measurement quality can affect both the quality of health care decisions and decisions about health care policy. The accompanying articles in this issue highlight a subset of measurement issues that have applicability to the broad community of health services research. It is our hope that they stimulate a broad discussion of the measurement challenges posed by conducting "state-of-the-art" health services research.

The evolving use of cost-effectiveness analysis in formulary management within the Department of Veterans Affairs.

The Veterans Health Administration (VHA) runs the largest integrated healthcare system in the nation. Formulary management within VHA primarily involves 3 national groups: the Medical Advisory Panel, the Veterans Integrated Service Network Formulary Leaders, and the Pharmacy Benefits Management Strategic Healthcare Group. Together, these groups manage the VHA national drug formulary with a goal of providing a comprehensive, safe, and cost-effective pharmacy benefit for veterans. Traditionally, VHA has relied on cost-minimization analyses in formulary decisions. More recently, VHA has emphasized the use of cost-effectiveness data, especially for newer, costly drugs. In addition to including this data in drug monographs, the VHA has begun requiring formal cost-effectiveness analysis from manufacturers of selected pharmaceuticals. VHA has also requested that clinically relevant information such as quality of life plus mortality benefit be made available from industry so that internal cost analyses can be performed. It is hoped that by setting the expectation that cost-effectiveness will be formally considered in all VHA formulary decisions, the pharmaceutical industry and others will be stimulated to collect and report data that enables these analyses. We believe that if other organizations also place an emphasis on economic evaluations, industry and the public will be more accepting of decisions that incorporate cost considerations.

An economic evaluation of inpatient residential treatment programs in the Department of Veterans Affairs.

The Veterans Health Administration (VA) established psychosocial residential rehabilitation treatment programs (RTPs) to treat eligible veterans who have psychiatric and substance use disorders in a less intensive and more self-reliant inpatient setting. Forty-two (25 percent) VA medical centers adopted RTPs in 1995. Panel regression models using data from 1993 through 1999 indicated that RTPs were associated with 8.6 and 24.4 percent decreases in the average cost per day for inpatient psychiatry and substance use care, respectively. During this time, VA transitioned much of the inpatient mental health care to ambulatory services. Yet medical centers with RTPs had smaller decreases in the number of inpatient patient days than those without RTPs. Because medical centers with RTPs provided more services, this offset the per diem savings, resulting in no significant differences in total costs between medical centers with and without RPTs.
