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

Study Design and Sampling in the Veterans Health Study

There are numerous choices to be made in the design of studies examining the impact of healthcare on patient-reported outcomes. We describe considerations in the design of the Veterans Health Study (VHS), a large-scale longitudinal observational study of healthcare in the Veterans Health Administration (VA). We also consider sampling issues, and discuss the broader theoretical and practical implications of our choices. The VHS was an observational study with a prospective longitudinal design. Subjects were recruited from a cross-sectional sample of the VA patient population, and identified when they came to ambulatory care clinics for a medical visit. Participating patients were contacted by telephone, and scheduled for an interview conducted at the clinic. Prior to the interview they completed a mailed questionnaire. The clinic interview included brief clinical assessments of selected study medical conditions, a medical history interview, limited health examination, and assessments of health status, health-related quality of life, process-of-care measures related to utilization of services, and other patient characteristics. Patients were empaneled and followed over time. Their health was monitored with brief mailed questionnaires completed at 3-month intervals, and with annual patient reassessments at 12 and 24 months. This design had several strengths. Its comprehensiveness and observational nature allowed for examination of a broad range of outcomes and processes of care as they occur in routine practice in the VA system. Study effects on outcomes should be minimal and the longitudinal design permitted the examination of changes in health status and evaluation of the extent to which changes in patients' illnesses and their treatments were associated with changes in outcomes. Many aspects of this study's design were innovative, reflecting careful consideration of design choices and lessons learned from previous outcomes research studies. Choices made in the design of the VHS can serve as models for future studies of the effects of healthcare on patient-reported outcomes.

Depression management in medical clinics: does healthcare sector make a difference?

Medical providers often fail to treat depression. We examined whether treatment is more aggressive in a setting with accessible mental health resources, the Veterans Health Administration (VA). VA and non-VA primary care physicians and medical specialists viewed a videotape vignette portraying a patient meeting criteria for major depression and then answered interviewer-administered questions about management. We found that 24% of VA versus 15% of non-VA physicians would initiate guideline-recommended treatment (antidepressants or mental health referral, or both) (P = .09). Among those who identified depression as likely, 42% of VA versus 19% of non-VA physicians would treat (P = .002): 23% versus 3% recommended mental health referral (P < .001) and 21% versus 17% an antidepressant (P = .67). Although many patients with major depression may not receive guideline-recommended management, VA physicians do initiate mental health referral more often than do non-VA physicians. Access to mental health services may prove valuable in the campaign to increase physician adherence to depression clinical guidelines.

Intraindividual change in SF-36 in ambulatory clinic primary care patients predicted mortality and hospitalizations

OBJECTIVE

We sought to determine whether change in SF-36 scores over time is associated with the risk of adverse outcomes.

STUDY DESIGN AND SETTING

7,702 participants in the Ambulatory Care Quality Improvement Project who completed a baseline and 1-year SF-36. Using logistic regression methods we estimated the 1-year risk of hospitalization and death based on previous 1-year changes in the physical (PCS) and mental (MCS) component summary scores.

RESULTS

After adjusting for baseline PCS scores, age, VA hospital site, distance to VA, and comorbidity, a >10-point decrease in PCS score was associated with an increased risk of death (OR 2.3, 95% CI 1.6-3.4) and hospitalization (OR 1.8, 1.4-2.2). An increased risk was also seen with a >10-point decrease in the MCS (OR for death, 1.6, 1.1-2.3; OR for hospitalization 1.5, 1.2-1.8).

CONCLUSION

Change in SF-36 PCS and MCS scores is associated with mortality and hospitalizations, and provides important prognostic information over baseline scores alone.

Patient-reported measures of health: The Veterans Health Study

The goal of the Veterans Health Study (VHS) was to extend the work of the Medical Outcomes Study (MOS) into the VA, by developing methodology for monitoring patient-based outcomes of care for use in ambulatory outpatient care. The principal objective of the VHS was developing valid and reliable measures to assess general health-related quality of life (HRQoL) and identifying the presence of selected health conditions, their severity, and their impact on HRQoL. In this article, we provide an overview of the historical context, framework, objectives, and applications of the VHS for the purpose of assessing the health outcomes of veteran patients. The VHS is a prospective observational study that has followed 2425 VA patients for up to 2 years. The patients were sampled from users of the Veterans Affairs (VA) ambulatory care system in the Boston area. The health conditions selected were hypertension, diabetes, chronic lung disease, osteoarthritis of the knee, chronic low-back pain, and alcohol-related problems. These conditions were chosen because they are both prevalent in the VA and have measurable impacts on HRQoL. One of the cornerstones of the VHS was the development of the Veterans SF-36, modified from the MOS SF-36 for use in veteran ambulatory populations. Other key accomplishments included the development of patient-based disease-specific measures of health and the establishment of methods and logistics for comprehensive health outcomes research in large health care systems such as the VA, using these patient-based measures. Selected measures developed in the VHS, eg, the Veterans SF-36, have been integrated into the VA outcomes measurement system. The scope of the VHS is unique; it resulted in the development of a broad range of patient-focused process and outcome measures, as well as methodologies for assessing large numbers of patients, that have been widely used in the VA outpatient health care system for monitoring health outcomes across the nation.

Use of VA health care services by women veterans: findings from a national sample

The Department of Veterans Affairs (VA) has a Congressional mandate but few empirical data on which to design and improve national health care services for women. We examined characteristics associated with women's current, former and non-use of the VA health care system. The study included 1,500 female veterans sampled from the Department of Veterans Affairs National Registry of Women Veterans. Women completed a 45-minute telephone survey assessing multiple domains of functional status and health service use. Using multivariate logistic regression, use of VA health care was associated with older age, more education, not being married, lower rates of insurance coverage, and poorer physical and psychological health. Women who were former users of VA health care were more likely to be ethnic minorities, have children, served less time in the military, had higher rates of insurance coverage and better physical and psychological health than current users. Prominent military experiences (e.g., service in a war-zone, exposure to trauma) were associated with former use and never using the VA health care system. Women who use VA health care are at greater economic, social, and health risk than nonusers, factors that have personal implications for the veteran as well as cost and service implications for VA. Additional research is needed to better understand the role of military experiences in women veterans' choice of health care.

Integrating clinical nurse specialists into the treatment of primary care patients with depression

OBJECTIVE

To examine the effectiveness of integrating generalist and specialist care for veterans with depression.

METHOD

We conducted a randomized trial of patients screening positive for depression at two Veterans Affairs Medical Center general medicine clinic firms. Control firm physicians were notified prior to the encounter when eligible patients had PRIME-MD depression diagnoses. In the intervention firm, a mental health clinical nurse specialist (CNS) was to: design a treatment plan; implement that plan with the primary care physician; and monitor patients via telephone or visits at two weeks, one month and two months. Primary outcomes (depressive symptoms, patient satisfaction with health care) were collected at 3 and 12 months.

RESULTS

Of 268 randomized patients, 246 (92%) and 222 (83%) completed 3- and 12-month follow-up interviews. There were no between-group differences in depressive symptoms or satisfaction at 3 or 12 months. The intervention group had greater chart documentation of depression at baseline (63% versus 33%, p = 0.003) and a higher referral rate to mental health services at 3 months (27% versus 9%, p = 0.019). There was no difference in the rate of new prescriptions for, or adequate dosing of, anti-depressant medications. In 40% of patients, CNSs disagreed with the PRIME-MD depression diagnosis, and their rates of watchful waiting were correspondingly high.

CONCLUSIONS

Implementing an integrated care model did not occur as intended. Experienced CNSs often did not see the need for treatment in many primary care patients identified by the PRIME-MD. Integrating integrated care models in actual practice may prove challenging.

Productivity of Veterans Health Administration laboratories: a College of American Pathologists Laboratory Management Index Program (LMIP) study

CONTEXT

The Veterans Health Administration (VA) operates the largest integrated laboratory network in the United States.

OBJECTIVE

To assess whether the unique characteristics of VA laboratories impact efficiency of operations, we compared the productivity of VA and non-VA facilities.

DESIGN

Financial and activity data were prospectively collected from 124 VA and 131 non-VA laboratories enrolled in the College of American Pathologists Laboratory Management Index Program (LMIP) during 2002. In addition, secular trends in 5 productivity ratios were calculated for VA and non-VA laboratories enrolled in LMIP from 1997 through 2002.

RESULTS

Veterans Health Administration and non-VA facilities did not differ significantly in size. Inpatients accounted for a lower percentage of testing at VA facilities than non-VA facilities (21.7% vs 37.3%; P <.001). Technical staff at the median VA facility were paid more than at non-VA facilities (28.11/h dollars vs 22.60/h dollars, salaries plus benefits; P <.001), VA laboratories employed a smaller percentage of nontechnical staff (30.0% vs 41.9%; P <.001), and workers at VA laboratories worked less time per hour paid (85.5% vs 88.5%; P <.001). However, labor productivity was significantly higher at VA than at non-VA facilities (30 448 test results/total full-time equivalent (FTE)/y vs 19 260 results/total FTE; P <.001), resulting in lower labor expense per on-site test at VA sites than at non-VA sites (1.79 dollars/result vs 2.08 dollars/result; P <.001). Veterans Health Administration laboratories paid less per test for consumables (P =.003), depreciation, and maintenance than their non-VA counterparts (all P <.001), resulting in lower overall cost per on-site test result (2.64 dollars vs 3.40 dollars; P <.001). Cost per referred (sent-out) test did not differ significantly between the 2 groups. Analysis of 6-year trends showed significant increases in both VA (P <.001) and non-VA (P =.02) labor productivity (on-site tests/total FTE). Expenses at VA laboratories for labor per test, consumables per test, overall expense per test, and overall laboratory expense per discharge decreased significantly during the 6-year period (P <.001), while in non-VA facilities the corresponding ratios showed no significant change.

CONCLUSIONS

Overall productivity of VA laboratories is superior to that of non-VA facilities enrolled in LMIP. The principal advantages enjoyed by the VA are higher-than-average labor productivity (tests/FTE) and lower-than-average consumable expenses.

Tooth loss and dentures: Patients’ perspectives

OBJECTIVE

Despite dramatic improvements in tooth retention around the world, a substantial proportion of older adults have lost natural teeth and many wear removable partial and complete dentures. Problems associated with tooth loss and denture wearing remain important in the context of global ageing. The purpose of this paper is to examine the effects of tooth loss and denture wearing on their day-to-day lives from the patient perspective.

DESIGN

Cross-sectional study.

SETTING

Greater Boston area, USA.

PARTICIPANTS

Community-dwelling older men.

METHODS

Brief examination and survey.

MAIN OUTCOME MEASURES

Self-reported oral health measures including the single-item self-rating of oral health, the Oral Health Impact Profile (OHIP), the Geriatric Oral Health Assessment Index (GOHAI), Oral-Health-related Quality of Life (OHQOL) and a newly-developed short-form instrument (the DELTA).

RESULTS

Men with > or = 25 teeth had better self-rated oral health by all measures. The new, brief DELTA differentiates between dentition/denture groupings as well as or better than existing instruments. Over 80% of men with > or = 25 teeth rated their oral health as excellent, very good or good, compared with 70% of men with no teeth (and dentures) and 54% of men with 1-24 teeth. Avoidance of certain foods discriminates well between dentition groups. To a lesser extent, difficulty with relaxation, pain and distress, and avoidance of going out are associated with tooth loss and/or denture wearing.

Patients' perceptions of quality of life after treatment for early prostate cancer

PURPOSE

Treatment for early prostate cancer produces problematic physical side effects, but prior studies have found little influence on patients' perceived health status. We examined psychosocial outcomes of treatment for early prostate cancer.

PATIENTS AND METHODS

Patients with previously treated prostate cancer and a reference group of men with a normal prostate-specific antigen (PSA) level and no history of prostate cancer completed questionnaires. Innovative scales assessed behavioral consequences of urinary dysfunction, sexuality, health worry, PSA concern, perceived cancer control, treatment decision making, decision regret, and cancer-related outlook. Urinary, bowel, and sexual dysfunction were assessed with symptom indexes; health status was assessed by the Physical and Mental Summaries of the Short Form (SF-12) Health Survey.

RESULTS

Compared with men without prostate cancer, prostate cancer patients reported greater urinary, bowel, and sexual dysfunction, but similar health status. They reported worse problems of urinary control, sexual intimacy and confidence, and masculinity, and greater PSA concern. Perceptions of cancer control and treatment decisions were positive, but varied by treatment: prostatectomy patients indicated the highest and observation patients indicated the lowest cancer control. Bowel and sexual dysfunction were associated with poorer sexual intimacy, masculinity, and perceived cancer control; masculinity and PSA concern were associated with greater confidence in treatment choice; and diminished sexual intimacy and less interest in PSA were associated with greater regret.

CONCLUSION

The lack of change in global measures of health status after treatment for early prostate cancer obscures important influences in men's lives; cancer diagnosis and treatment complications may result in complex outcomes. Aggressive treatment may confer confidence in cancer control, yet be countered by diminished intimate relationships and masculinity, which accompany sexual dysfunction.

Inhaled corticosteroids in chronic obstructive pulmonary disease and risk of death and hospitalization: time-dependent analysis

Observational studies of inhaled corticosteroids in chronic obstructive pulmonary disease (COPD) have shown improved survival whereas randomized trials have not. It has been suggested that this difference may be due to immortal time bias. To investigate this further, we performed a prospective cohort study of patients with COPD, using time-dependent methods to determine whether use of inhaled corticosteroids more than 80% of the time reduced the risk of all-cause mortality and COPD exacerbations. Of 8,033 patients, 2,686 (33%) received inhaled corticosteroids. We did not find a significant reduction in mortality for average inhaled steroid use at either low (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.69-1.33) or medium/high dose (HR, 0.86; 95% CI, 0.67-1.10). Similarly, recent inhaled corticosteroid use was not associated with a reduction in mortality at low (HR, 0.80; 95% CI, 0.60-1.07) or medium/high doses (HR, 0.88; 95% CI, 0.71-1.09). There was no association between inhaled corticosteroid use and hospitalizations or exacerbations due to COPD. Patients using medium/high-dose inhaled corticosteroids did not have a significantly lower risk of COPD hospitalizations (HR, 0.85; 95% CI, 0.64-1.13) or COPD exacerbations (HR, 1.13; 95% CI, 0.94-1.36). In a time-dependent study of outpatients with COPD, adherence to inhaled corticosteroid use was not associated with a decreased risk of mortality or exacerbations.

Impact of angina burden and other factors on treatment satisfaction after acute coronary syndromes

PURPOSE

Although of great importance to clinicians, hospitals, and health care systems, little is known about factors that influence treatment satisfaction after acute coronary syndromes (ACS). The objective of this study was to identify potentially modifiable factors associated with treatment satisfaction 7 months after ACS.

METHODS

The study population included 1957 patients with ACS who were enrolled in the multicenter, prospective Veterans' Health Administration Access to Cardiology Study. The primary outcome was treatment satisfaction 7 months after ACS as measured by the Seattle Angina Questionnaire. Multivariable regression models were developed to determine the association between treatment satisfaction and patient characteristics, physician-patient communication, and current angina frequency.

RESULTS

Patient characteristics associated with reduced treatment satisfaction included a history of depression, atrial fibrillation, prior heart surgery, arthritis, hypertension, younger age, and a discharge diagnosis of unstable angina (as opposed to myocardial infarction). After adjusting for patient characteristics, patient-reported inability to reach one or more of their physicians (OR, 2.40; 95% CI, 1.47 to 3.91), being given confusing information (OR, 3.48; 95% CI, 2.08 to 5.83), and poor overall communication with one or more of their physicians (OR, 4.94; 95% CI, 2.93 to 8.34) were all associated with reduced satisfaction. Finally, after adjustment for both patient characteristics and physician communication, weekly (OR, 3.52; 95% CI, 2.28 to 5.45) and daily angina (OR, 3.88; 95% CI, 2.23 to 6.75) were associated with worse treatment satisfaction.

CONCLUSIONS

Current angina symptoms and aspects of physician communication are independently associated with treatment satisfaction after ACS. These results suggest that treatment satisfaction may be improved through better communication and better control of angina symptoms.

Racial/ethnic variations in physician recommendations for cardiac revascularization

OBJECTIVES

We sought to examine whether physician recommendations for cardiac revascularization vary according to patient race.

METHODS

We studied patients scheduled for coronary angiography at 2 hospitals, one public and one private, between November 1997 and June 1999. Cardiologists were interviewed regarding their recommendations for cardiac resvacularization.

RESULTS

African American patients were less likely than Whites to be recommended for revascularization at the public hospital (adjusted odds ratio [OR] = 0.31; 95% confidence interval [CI] = 0.12, 0.77) but not at the private hospital (adjusted OR = 1.69; 95% CI = 0.69, 4.14).

CONCLUSIONS

Physician recommendations for cardiac revascularization vary by patient race. Further studies are needed to examine physician bias as a factor in racial disparities in cardiac care and outcomes.

Quality of life, impotence, and activity level in a randomized trial of immediate repair versus surveillance of small abdominal aortic aneurysm

OBJECTIVE

We compared long-term health-related quality-of-life outcome after randomization to immediate elective repair or imaging surveillance, and in relation to time of elective repair, in patients with small asymptomatic abdominal aortic aneurysm (AAA).

METHODS

This randomized clinical trial was carried out in 16 Veterans Affairs medical centers. Study subjects were patients at good surgical risk, aged 50 to 79 years, with AAAs 4.0 to 5.4 cm in diameter. Interventions included immediate open surgical AAA repair or imaging surveillance every 6 months with repair reserved for AAAs that became symptomatic or enlarged to 5.5 cm. Main outcome measures considered were SF-36 health status questionnaire, prevalence of impotence, and maximum activity level, which were determined at randomization and at all follow-up visits.

RESULTS

Eleven hundred thirty-six patients were randomized and followed up for 3.5 to 8 years (mean, 4.9 years). The two randomized groups did not differ significantly for most SF-36 scales at most times, but the immediate repair group scored higher overall in general health (P <.0001), which was particularly evident in the first 2 years after randomization, and slightly lower in vitality (P <.05). The baseline value of one SF-36 scale, physical functioning, was an independent predictor of mortality. Overall, more patients became impotent after randomization to immediate repair compared with surveillance (P <.03), but this difference did not become apparent until more than 1 year after randomization. Maximum activity level did not differ significantly between the two randomized groups, but decline over time was significantly greater in the immediate repair group (P <.02).

CONCLUSIONS

For most quality-of-life measures and times there was no difference between randomized groups. Immediate repair resulted in a higher prevalence of impotence more than 1 year after randomization, but was also associated with improved perception of general health in the first 2 years.

Palliative Care Management: A Veterans Administration Demonstration Project

As part of a Veterans Health Administration (VA) commitment to improve end-of-life care the VA Greater Los Angeles Healthcare System (GLA) implemented Pathways of Caring, a 3-year demonstration project targeting patients with inoperable lung cancer and advanced heart failure and chronic lung disease. The program utilized case-finding for early identification of poor-prognosis patients, interdisciplinary palliative assessment, and intensive nurse care coordination to optimize symptom management, continuity and coordination of services across providers and care settings, and support for families. Program evaluation used patient and family surveys as well as reviews of medical records and administrative databases to assess processes and outcomes of care. Despite significant programmatic challenges including organizational instability and evaluation design issues, the program achieved measurable success including high rates of advance care planning, hospice enrollment, and death at home, and low end-of-life hospital and Intensive Care Unit (ICU) use. As a result of its success, the program will be expanded and its care model extended institution-wide.

Opening a Window of Opportunity through Technology and Coordination: A Multisite Case Study

The Community Care Coordination Service (CCCS) program was implemented in April, 2000, at the Veterans Integrated Service Network (VISN 8). The goals of the CCCS were to improve the coordination of care for clinically complex patients, referred to as veterans, and to increase their access to care while reducing complications, hospital admissions, and emergency room (ER) visits. This program used a coordinated care approach, a process whereby veterans were followed throughout the continuum of care. The information presented in this case study is specific to three medical centers that implemented the CCCS: Ft. Myers, Lake City, and Miami. Analysis of utilization and clinical impact were conducted after 18 months. Inpatient admissions were reduced by 46% at Ft. Myers, 68% at Lake City, and 13% at Miami. ER encounters were reduced by 19% at Ft. Myers, 70% at Lake City, and 15% at Miami. Reductions in bed days were demonstrated at Ft. Myers (29%) and Lake City (71%). In Miami, there was a 13% increase in the number of bed days of care for the patients after 1 year in the program. In addition to these changes in health-care utilization, quality of life was significantly improved as evidenced by increases in the four of the eight components scores of the Medical Outcomes Study 36-item Short Form health survey for veterans (SF36V) at Lake City and Ft. Myers. In the CCCS model of care using home telehealth technology, the Care Coordinators bridged the gap between office visits by providing a daily connection between the coordinators and the patients. This daily communication made it possible for problems to be identified early and interventions implemented before problems escalated.

Enhancing elder chronic care through technology and care coordination: report from a pilot

The Rural Home Care Project is one of eight clinical demonstration pilots in an initiative of the Veterans Health Administration (VHA) Sunshine Network in Florida and Puerto Rico. In this project three care coordinators consisting of two nurse practitioners and a social worker collaborate with primary care providers in the management of high-risk, high-cost veterans with multiple chronic diseases such as diabetes and heart failure. The project staff uses home telehealth devices to monitor and educate patients to prevent health crises. The evaluation methodology is a quasiexperimental design that uses a nonequivalent control group of usual care veterans. Data were gathered through personal interviews with patients and providers, and statistical analysis was based on a series of repeated-measure of covariance modeling designed by a research team from the University of Maryland. Findings demonstrate that care coordination enhanced by technology reduces hospital admissions, bed days of care, emergency room visits, and prescriptions as well as providing high patient and provider satisfaction. Veterans also had improved perception of physical health as evidenced by a standardized functional status measure.

Tooth retention as an indicator of quality dental care: development of a risk adjustment model

BACKGROUND

Retaining teeth improves oral health and quality of life. Thus, receipt of a root canal (vs. a tooth extraction) is a useful indicator of the quality of dental care. However, use of this quality measure without adjusting for the severity of oral disease could lead to spurious conclusions.

OBJECTIVES

This paper describes the development of a dental severity adjustment methodology.

RESEARCH DESIGN

Retrospective study.

SUBJECTS

54,423 users of Department of Veterans Affairs (VA) dental care who had either root canal therapy or a tooth extraction at a VA facility in Fiscal year 1998.

MEASURES

International Classification of Disease Clinical Modification codes for dental diagnoses and comorbid medical conditions. We modeled the effects of dental disease severity in logistic regression models of the probability of receiving a root canal, using both conceptual and Modified Delphi-Panel derived models, adjusting for age, and medical comorbidities.

RESULTS

Conceptual and Modified Delphi models performed similarly. The dental disease severity adjustments increased the fit in models of the probability of receiving a root canal (C-statistic = 0.822 for the conceptual model and 0.804 for the Modified Delphi Panel model) compared with the model including comorbid medical conditions alone (C-statistic = 0.561).

CONCLUSIONS

Risk adjustment for dental disease severity improves the fit of models of the probability of receiving a root canal. Studies of the quality of dental care should consider employing risk-adjusted models.

Measuring patients' perceptions of the outcomes of treatment for early prostate cancer

BACKGROUND

Compared with careful attention to the physical (eg, urinary, bowel, sexual) dysfunction that may follow treatment, little attention has been given to the behavioral, emotional, and interpersonal changes that the diagnosis of early prostate cancer and subsequent physical dysfunction may bring.

OBJECTIVE

To construct patient-centered measures of the outcomes of treatment for early prostate cancer.

RESEARCH DESIGN

Qualitative study followed by survey of early prostate cancer patients and group of comparable patients with no history of prostate cancer. Analysis of focus groups identified relevant domains of quality of life, which were represented by Likert scale items included in survey questionnaires. Psychometric analyses of survey data defined scales evaluated with respect to internal consistency and validity.

RESULTS

Qualitative analysis identified three domains: urinary control, sexuality, and uncertainty about the cancer and its treatment. Psychometric analysis defined 11 scales. Seven were generically relevant to most older men: urinary control (eg, embarrassment with leakage), sexual intimacy (eg, anxiety about completing intercourse), sexual confidence (eg, comfort with sexuality), marital affection (eg, emotional distance from spouse/partner), masculine self esteem (eg, feeling oneself a whole man), health worry (eg, apprehensiveness about health changes), and PSA concern (eg, closely attending to one's PSA). Four scales were specific to the treatment experience: perceived cancer control, quality of treatment decision making, regret of treatment choice, and cancer-related outlook.

CONCLUSION

The scales provide definition and metrics for patient-centered research in this area. They complement measures of physical dysfunction and bring into resolution outcomes of treatment that have gone unnoticed in previous studies.

Xerostomic medications and oral health: the Veterans Dental Study (part I)

OBJECTIVES

To quantify the adverse effects of the number of xerostomic medications on dental caries, oral mucosa, and periodontal disease.

DESIGN

Secondary analysis of a cross-sectional study of the Veterans Dental Study.

SETTING

Four New England area VA outpatient clinics.

SUBJECTS

The sample consists of 345 male veterans participating in The Veteran's Dental Study who also had pharmacy records.

MAIN OUTCOME MEASURES

Oral health data included total surfaces of coronal caries, a modification of the root caries index, mean oral mucosa scores, and Community Periodontal Index of Treatment Need (CPITN). Oral health parameters were measured and recorded in clinical dental examinations.

EXPOSURES

Intake of xerostomic medications 14-385 days prior to the dental examination.

STATISTICAL ANALYSES

The relationships between exposure and outcome were analyzed via linear and logistic regression methods adjusting for possible confounding factors such as disease burden index, alcohol consumption, dental care, and smoking status.

RESULTS

Veterans who were taking at least one xerostomic medication were almost three times more likely to have mean mucosa scores in the worst 25 percentile than veterans taking no xerostomic medications, OR = 2.63 (confidence interval [CI] 1.34, 5.16, p = 0.03) after adjusting for age, number of teeth, disease burden index, income, smoking and alcohol use. Participants who were taking at least one xerostomic medication experienced higher but non-significant increases in coronal (OR = 1.21; CI. 0.66, 2.25) and root caries (OR = 1.10 CI. 0.54, 2.24) measured by numbers of total decayed surfaces.

CONCLUSION

There were significant deleterious effects of xerostomic medications on oral mucosa. However, xerostomic medications do not appear to increase coronal caries, or periodontal index measured by CPITN among ambulatory, community dwelling participants who were able to perform routine preventive oral care.

COPD in VA hospitals

The Department of Veterans Affairs (VA) Health Care System is the largest integrated single-payer system in the United States. Its primary mission is to provide primary care, specialized care, and related medical and social support services to veterans. Much time and resources are expended on chronic obstructive pulmonary disease, known as COPD, at VA hospitals and clinics, thereby justifying the development of multifaceted strategies to address this problem. This article discusses the special problems of COPD in veterans who use VA facilities. The article also highlights the contributions of the VA to the research, training, and development of clinical practice guidelines for the management of this pervasive disease and presents the challenges that threaten its role in this area.

Construction and characteristics of the RxRisk-V: a VA-adapted pharmacy-based case-mix instrument

BACKGROUND

Assessment of disease burden is the key to many aspects of health care management. Patient diagnoses are commonly used for case-mix assessment. However, issues pertaining to diagnostic data availability and reliability make pharmacy-based strategies attractive. Our goal was to provide a reliable and valid pharmacy-based case-mix classification system for chronic diseases found in the Veterans Health Administration (VHA) population.

OBJECTIVE

To detail the development and category definitions of a VA-adapted version of the RxRisk (formerly the Chronic Disease Score); to describe category prevalence and reliability; to check category criterion validity against ICD-9 diagnoses; and to assess category-specific regression coefficients in concurrent and prospective cost models.

RESEARCH DESIGN

Clinical and pharmacological review followed by cohort analysis of diagnostic, pharmacy, and utilization databases.

SUBJECTS

126,075 veteran users of VHA services in Washington, Oregon, Idaho, and Alaska.

METHODS

We used Kappa statistics to evaluate RxRisk category reliability and criterion validity, and multivariate regression to estimate concurrent and prospective cost models.

RESULTS

The RxRisk-V classified 70.5% of the VHA Northwest Network 1998 users into an average of 2.61 categories. Of the 45 classes, 33 classes had good-excellent 1-year reliability and 25 classes had good-excellent criterion validity against ICD-9 diagnoses. The RxRisk-V accounts for a distinct proportion of the variance in concurrent (R2 = 0.18) and prospective cost (R2 = 0.10) models.

CONCLUSIONS

The RxRisk-V provides a reliable and valid method for administrators to describe and understand better chronic disease burden of their treated populations. Tailoring to the VHA permits assessment of disease burden specific to this population.

Effect of the transformation of the Veterans Affairs Health Care System on the quality of care

BACKGROUND

In the mid-1990s, the Department of Veterans Affairs (VA) health care system initiated a systemwide reengineering to, among other things, improve its quality of care. We sought to determine the subsequent change in the quality of health care and to compare the quality with that of the Medicare fee-for-service program.

METHODS

Using data from an ongoing performance-evaluation program in the VA, we evaluated the quality of preventive, acute, and chronic care. We assessed the change in quality-of-care indicators from 1994 (before reengineering) through 2000 and compared the quality of care with that afforded by the Medicare fee-for-service system, using the same indicators of quality.

RESULTS

In fiscal year 2000, throughout the VA system, the percentage of patients receiving appropriate care was 90 percent or greater for 9 of 17 quality-of-care indicators and exceeded 70 percent for 13 of 17 indicators. There were statistically significant improvements in quality from 1994-1995 through 2000 for all nine indicators that were collected in all years. As compared with the Medicare fee-for-service program, the VA performed significantly better on all 11 similar quality indicators for the period from 1997 through 1999. In 2000, the VA outperformed Medicare on 12 of 13 indicators.

CONCLUSIONS

The quality of care in the VA health care system substantially improved after the implementation of a systemwide reengineering and, during the period from 1997 through 2000, was significantly better than that in the Medicare fee-for-service program. These data suggest that the quality-improvement initiatives adopted by the VA in the mid-1990s were effective.

Making the right connection: matching patients to technology

Although technology has sometimes been the cause of rising healthcare costs, telemedicine technology has been proposed as a means to increase productivity in the workplace and reduce resource utilization for high-risk populations. The Veterans Health Administration (VHA) in April of 2000, implemented an expansive telemedicine technology initiative in its Sunshine Network, covering veterans in south Georgia, Florida, Puerto Rico, and the Virgin Islands through the Community Care Coordination Service (CCCS). The initiative uses home telehealth technology to support veteran healthcare. Choosing appropriate tools to enhance care coordination and matching technology to specific patient needs was vital to the success of the CCCS model. A technology algorithm was developed across the Network initiative and grew out of a need to identify and benchmark best practices. An evaluation methodology developed by a health economist and his research team at the University of Maryland was used to determine patient satisfaction with technology and functional status through a validated instrument. Outcomes were for 791 chronic medical and 120 mental health patients. Patient satisfaction was extremely high, patients used technology without difficulty and acceptance was greater than expected. Patients' perception of health as surveyed with the functional status instrument showed improved perception in many factors including pain, physical, and social functioning.

The health and functional status of US veterans aged 65+: implications for VA health programs serving an elderly, diverse veteran population

As the US population is aging, so too is the US veteran population. Chief among the challenges facing the Department of Veterans Affairs (VA) is developing health programs and services that mesh with the needs of an aging veteran population and therefore improve the health status of elderly veterans. Meeting this challenge requires an understanding of the health needs of the older veteran population, including health disparities that exist across racial ethnic populations. This study examines the self-rated health and functioning of a national sample of veterans aged 65+ participating in the National Survey of Veterans. The results show that over one half of elderly veterans report difficulty in functioning and rate their health status as fair or poor. Additionally, elderly African American and Hispanic veterans report worse health than non-Hispanic white veterans across the majority of health indicators. Given the health profile of older veterans found in this study, it would seem necessary that programs serving older veterans be adept at the ongoing medical management of chronic disease and the provision of long-term care services.

Measuring the quality of depression care in a large integrated health system

BACKGROUND

Guideline-based depression process measures provide a powerful way to monitor depression care and target areas needing improvement.

OBJECTIVES

To assess the adequacy of depression care in the Veterans Health Administration (VHA) using guideline-based process measures derived from administrative and centralized pharmacy records, and to identify patient and provider characteristics associated with adequate depression care.

RESEARCH DESIGN

This is a cohort study of patients from 14 VHA hospitals in the Northeastern United States which relied on existing databases. Subject eligibility criteria: at least one depression diagnosis during 1999, neither schizophrenia nor bipolar disease, and at least one antidepressant prescribed in the VHA during the period of depression care profiling (June 1, 1999 through August 31, 1999). Depression care was evaluated with process measures defined from the 1997 VHA depression guidelines: antidepressant dosage and duration adequacy. We used multivariable regression to identify patient and provider characteristics predicting adequate care.

SUBJECTS

There were 12,678 patients eligible for depression care profiling.

RESULTS

Adequate dosage was identified in 90%; 45% of patients had adequate duration of antidepressants. Significant patient and provider characteristics predicting inadequate depression care were younger age (<65), black race, and treatment exclusively in primary care.

CONCLUSIONS

Under-treatment of depression exists in the VHA, despite considerable mental health access and generous pharmacy benefits. Certain patient populations may be at higher risk for inadequate depression care. More work is needed to align current practice with best-practice guidelines and to identify optimal ways of using available data sources to monitor depression care quality.

Racial disparities in VA service connection for posttraumatic stress disorder disability

BACKGROUND

"Service connected" veterans are those with documented, compensative conditions related to or aggravated by military service, and they receive priority for enrollment into the Veterans Affairs (VA) health care system. For some veterans, service connection represents the difference between access to VA health care facilities and no access.

OBJECTIVES

To determine whether there are racial discrepancies in the granting of service connection for posttraumatic stress disorder (PTSD) by the Department of Veterans Affairs and, if so, to determine whether these discrepancies could be attributed to appropriate subject characteristics, such as differences in PTSD symptom severity or functional status.

RESEARCH DESIGN

Mailed survey linked to administrative data. Claims audits were conducted on 11% of the sample.

SETTING AND SUBJECTS

The study comprised 2700 men and 2700 women randomly selected from all veterans filing PTSD disability claims between January 1, 1994 and December 31, 1998.

RESULTS

A total of 3337 veterans returned usable surveys, of which 17% were black. Only 16% of respondents carried private health insurance, and 44% reported incomes of 20,000 US dollars or less. After adjusting for respondents' sociodemographic characteristics, symptom severity, functional status, and trauma histories, black persons' rate of service connection for PTSD was 43% compared with 56% for other respondents (P = 0.003).

CONCLUSION

Black persons' rates of service connection for PTSD were substantially lower than other veterans even after adjusting for differences in PTSD severity and functional status.

The relative health related quality of life of veterans with Parkinson's disease

OBJECTIVES

To use databases of the US Veterans Health Administration (VHA) to describe the impact of Parkinson's disease on health related quality of life (HRQoL) of veterans; to compare the HRQoL of veterans with Parkinson's disease with that of veterans reporting eight other neurological or chronic conditions; and to estimate the unique effect of Parkinson's disease on HRQoL.

METHODS

Respondents to the VHA 1999 large national health survey of veteran enrollees with a diagnosis of Parkinson's disease in VHA treatment files for the fiscal years 1997-1999 were identified by merging databases. The survey incorporated the Veterans SF-36, a well validated generic measure of HRQoL and functional status. This was used to compare patient groups. Mean physical (PCS) and mental (MCS) component summary scores were calculated for Parkinson's disease and eight other diseases by multivariable regressions that adjusted for age, sex, race, education, and 15 mental and physical co-morbid conditions that were self reported in the survey.

RESULTS

Of 887 775 survey respondents, 14 530 (1.64%) had a Parkinson's disease diagnosis. Controlling for sociodemographic factors and co-morbidities, veterans with Parkinson's disease had PCS and MCS below veterans with angina/coronary heart disease, arthritis, chronic low back pain, congestive heart failure, diabetes, and stroke. Veterans with spinal cord injury reported slightly lower PCS than veterans with Parkinson's disease (32.38 v 32.72; 0.03 of 1 SD). Veterans with depression reported markedly lower MCS than veterans with Parkinson's disease (35.94 v 41.48; 0.55 of 1 SD). The unique effect of having Parkinson's disease on HRQoL was to lower PCS and MCS by 4.10 and 3.42 points (0.41 and 0.34 of 1 SD), respectively.

CONCLUSIONS

The analysis quantifies the negative impact of Parkinson's disease on HRQoL, after controlling for sociodemographic factors and co-morbidities. Compared with eight other chronic conditions, Parkinson's disease imposes a relatively heavy burden on US veterans in the VHA health care system.

Agreement between patient self-report and a Veterans Affairs national pharmacy database for identifying recent exposures to antibiotics

PURPOSE

The dramatic rise in antibiotic drug resistance among community pathogens has stimulated interest in the epidemiological relationship between antibiotic exposure and drug resistance. In assessing the strength of this relationship, studies are hampered by the lack of data on the accuracy of subject self-report of antibiotic exposure. The authors compared self-report with pharmacy dispensing data to determine the accuracy of self-reported antibiotic exposure.

METHODS

The study design was a cross-sectional survey of veterans seen at the Philadelphia Veterans Affairs (VA) Medical Center in 1999 and 2000. Subjects reported exposures to antibiotics, antihypertensive drugs and nonsteroidal anti-inflammatory drugs through a structured telephone interview. The instrument included open-ended questions, condition-specific prompts and drug-specific prompts. Subject responses were linked to a national VA pharmacy database that served as the reference standard for evaluating self-reported exposures.

RESULTS

The authors found that the sensitivity of self-report of antibiotic exposure increased with increasing use of prompts. A comprehensive assessment of antibiotic exposure identified 73% of antibiotic exposures, compared to 73% of antihypertensive drug exposures and 92% of nonsteroidal anti-inflammatory drug exposures.

CONCLUSIONS

Assessment of antibiotic exposure appears to be comparable to assessment of other chronic and episodic drugs. Multistep assessment of exposure improves the sensitivity of assessment.

Cancer breakthrough pain characteristics and responses to treatment at a VA medical center

The purpose of this study is to analyze cancer breakthrough pain (BP) characteristics and how BP responds to conventional cancer pain management. Seventy-four cancer pain patients with worst pain severity >or=4 out of 10 completed the Brief Pain Inventory (BPI), Memorial Symptom Assessment Scale-Short Form, Functional Assessment Cancer Therapy and Breakthrough Pain Questionnaires (BPQ) at an initial interview. Agency for Health Care Policy and Research (AHCPR) cancer pain management guidelines were followed. Pain syndromes and morphine equivalent daily dose (MEDD) orally were determined. One-week follow-up assessments were obtained in 66 patients with BPI and BPQ. The BP characteristics were similar at both time points. On day 1, 52 patients (70%) had BP, and the BP was unpredictable in 30 patients (58%). The median time to worst BP severity was 3 min. Patients with BP had significantly higher worst pain (P<0.001). At week 1, the median MEDD doubled from 60 to 120 mg orally, and the number of patients who received adjuvant analgesics doubled from 31.1% (23 patients) on day 1 to 62.2% (41 patients). At week 1, 21 patients (32%) remained without BP, 21 patients (32%) were classified as BP responders and 24 patients (36%) were BP non-responders. The mean pain relief was similar for all three subgroups, i.e. around 80%. Compared to BP responders, BP non-responders had significantly higher worst pain (P<0.0001), average pain (P<0.004), and higher BPI interference parameters and shorter time to worst pain severity. The study confirmed the applicability of the BPQ to an US veteran population, and that pain management following the AHCPR guidelines is effective for a group of patients with cancer related BP. Underlying pain syndromes and the BP location may influence the response of BP to treatment. Patients with bone pain located in the spine, back, and pelvis may be at risk for resistant BP.

Impoverished diabetic patients whose doctors facilitate their participation in medical decision making are more satisfied with their care

OBJECTIVE

Greater participation in medical decision making is generally advocated for patients, and often advocated for those with diabetes. Although some studies suggest that diabetic patients prefer to participate less in decision making than do healthy patients, the empirical relationship between such participation and diabetic patients' satisfaction with their care is currently unknown. We sought to characterize the relationship between aspects of diabetic patients' participation in medical decision making and their satisfaction with care.

DESIGN

Cross-sectional observational study.

SETTING

A general medical county hospital-affiliated clinic.

PARTICIPANTS

One hundred ninety-eight patients with type 2 diabetes.

MAIN MEASURES

Interviews conducted prior to the doctor visit assessed patients' desire to participate in medical decision making, baseline satisfaction (using a standardized measure), and sociodemographic and clinical characteristics. Postvisit interviews of those patients assessed their visit satisfaction and perception of their doctor's facilitation of patient involvement in care. A discrepancy score was computed for each subject to reflect the difference between the previsit stated desire regarding participation and the postvisit report of their experience of participation.

RESULTS

Overall, patients reported low postvisit satisfaction relative to national standards (mean of 70 on a 98-point scale). Patients perceived a high level of facilitation of participation (mean 88 on a 100-point scale). Facilitation of participation and the discrepancy score both independently predicted greater visit satisfaction. In particular, a 13-point (1 SD) increase in the perceived facilitation score resulted in a 12-point (0.87 SD) increase in patient satisfaction, and a 1.22 point increase (1 SD) in the discrepancy score (the extent to which the patient was allowed more participation than, at previsit, he or she desired) resulted in a 6-point (0.5 SD) increase in the satisfaction score, even after controlling for initial desire to participate. For women, but not for men, physician facilitation of participation was a positive predictor of satisfaction; for men, but not women, desire to participate was a significant positive predictor of visit satisfaction.

CONCLUSION

Clinicians may feel reassured that encouraging even initially reluctant patients with diabetes to participate in medical decision making may be associated with increased patient satisfaction. Greater patient participation has the potential to improve diabetic self-care because of the likely positive effect of patient satisfaction on adherence to treatment. Further research to assess the prospective effects of enhancing physician facilitation of patient participation is likely to yield important information for the effective treatment of chronically ill patients.

Screening for post-traumatic stress disorder in female Veteran's Affairs patients: validation of the PTSD checklist

We evaluated the screening validity of a self-report measure for post traumatic stress disorder (PTSD), the PTSD Checklist (PCL), in female Veterans Affairs (VA) patients. All women seen for care at the VA Puget Sound Health Care system from October 1996-January 1999 (n=2,545) were invited to participate in a research interview. Participants (n=282) completed the 17-item PCL, followed by a gold standard diagnostic interview for PTSD, the Clinician Administered PTSD Scale (CAPS). Thirty-six percent of the participants (n=100) met CAPS diagnostic criteria for current PTSD. Receiver Operating Characteristic (ROC) analysis was used to evaluate the screening performance of the PCL. The area under the ROC curve was 0.86 (95% CI 0.82-0.90). A PCL score of 38 optimized the performance of the PCL as a screening test (sensitivity 0.79, specificity 0.79). The PCL performed well as a screening measure for the detection of PTSD in female VA patients.

Relationship between obesity and health-related quality of life in men

OBJECTIVE

Few studies examining the relationship between obesity and health-related quality of life (HRQOL) have used a medical outpatient population or demonstrated a relationship in men. Furthermore, most studies have not adequately considered comorbid illness. The goal of this study was to examine the relationship between body mass index (BMI) and HRQOL in male outpatients while considering comorbid illness.

RESEARCH METHODS AND PROCEDURES

This cross-sectional study examined 1168 male outpatients from Durham Veterans' Affairs Medical Center. Multiple linear regression was used to examine the relationship of BMI with each subscale from the Medical Outcomes Study Short Form 36 while adjusting for age, race, comorbid illness, depression, and physical activity.

RESULTS

Participants had a mean age of 54.7 +/- 5.6 years; 69% were white and 29% were African American. The distribution for BMI was as follows: 18.5 to <25 kg/m(2) (21%), 25 to <30 kg/m(2) (43%), 30 to <35 kg/m(2) (25%), 35 to <40 kg/m(2) (8%), and > or =40 kg/m(2) (3%). Mean Short Form 36 subscale scores were lower than U.S. norms by an average of 27%. Individuals with BMI > or =40 kg/m(2) had significantly lower scores compared with normal weight individuals on the Role-Physical and Vitality subscales. On the Physical Functioning and Physical Component subscales, lower scores were observed at BMI > or =35 kg/m(2). On the Bodily Pain subscale, lower scores were observed at BMI > or =25 kg/m(2).

DISCUSSION

An inverse relationship between BMI and physical aspects of HRQOL exists in a population of male outpatients. Increased BMI was most prominently associated with bodily pain; this relationship should receive more attention in clinical care and research.

The antibiotic treatment trial of Gulf War Veterans' Illnesses: issues, design, screening, and baseline characteristics

Many veterans who were deployed to the Persian Gulf during the 1990-1991 Gulf War developed multiple unexplained symptoms such as pain, fatigue, and neurocognitive problems. This constellation of symptoms has been termed Gulf War Veterans' Illnesses (GWVI). Although there is no proven explanation for the cause of GWVI, one fairly widespread explanation is systemic Mycoplasma fermentans infection. The Antibiotic Treatment Trial of GWVI is a randomized placebo-controlled trial to determine whether a 1-year course of doxycycline treatment in deployed Gulf War veterans with GWVI and testing as Mycoplasma species positive will improve their overall functional status as measured by the Physical Component Summary of the SF-36V questionnaire. The study of a multisymptom illness such as GWVI is complicated by the nonspecific nature of the illness, the unknown etiology, and the lack of a widely accepted outcome measure. The presumption of mycoplasma infection raises concerns regarding the methodology for determination of mycoplasma infection, the choice of treatment, and the duration of treatment. However, such a presumption allows the formulation of a clear testable hypothesis that can be tested with treatments with known rates of adverse events and known activity against Mycoplasma species. This paper describes the major issues faced by the investigators during planning, the study design, the patient screening results, and the baseline characteristics of the study patients. There were 2712 patients screened for study entry at 26 Department of Veterans Affairs and two Department of Defense medical centers. Of these, 491 met all study entry criteria and were randomized to either 1 year of doxycycline (200 mg/day) or 1 year of placebo. All patients were seen monthly during treatment and at 6 months after the end of treatment. Study patients had a mean age of 41 years and were mostly male (86%), white (64%), married (68%), and employed full-time (71%).

Effect of smoking, alcohol, and depression on the quality of life of head and neck cancer patients

This pilot study examined the relationship between smoking, alcohol intake, depressive symptoms and quality of life (QoL) in head and neck cancer patients. A questionnaire on smoking, alcohol, depressive symptoms and QoL was distributed to head and neck cancer patients (N=81). Over one-third (35%) of the respondents had smoked within the last 6 months, 46% had drunk alcohol within the last 6 months and 44% screened positive for significant depressive symptoms. About one-third (32%) of smokers were interested in smoking cessation services and 37% of patients with depressive symptoms were interested in depression services. However, only 9% of those who drank alcohol expressed interest in alcohol services. Smoking was negatively associated with five scales of the SF-36V including Physical Functioning, General Health, Vitality, Social Functioning, and Role-Emotional Health. Depressive symptoms were negatively associated with all eight scales on the SF-36V and all four scales of the Head and Neck Quality of Life instrument. Surprisingly, alcohol was not found to be associated with any of the QoL scales. While smoking, alcohol intake and depression may be episodically treated, standardized protocols and aggressive intervention strategies for systematically addressing these highly prevalent disorders are needed in this population.

Clinical relevance of fatigue levels in cancer patients at a Veterans Administration Medical Center

BACKGROUND

The correlation of fatigue levels with functional interference, symptom distress, and quality of life may help determine clinically significant fatigue levels.

METHODS

One hundred eighty consecutive patients with cancer completed the Functional Assessment of Cancer Therapy (FACT) General and Fatigue subscales (FACT-G and FACT-F, respectively), the Memorial Symptom Assessment Scale-Short Form (MSAS-SF), the Depression Scale (Zung), and the Brief Fatigue Inventory (BFI). The Karnofsky performance status (KPS) was determined for each patient. Multivariate analyses of variance were performed to compare fatigue models with different cut-off points to categorize fatigue levels. Cox proportional hazards analysis was performed to assess the association between fatigue severity and survival.

RESULTS

Increased fatigue levels were associated with greater symptom distress and decreased quality of life. A model with usual fatigue cut-off points of 0 (no fatigue), 1-2 (mild fatigue), 3-6 (moderate fatigue), and 7-10 (severe fatigue) was optimal in relation to functional interference items (Wilks lambda, 0.36; F = 11.61; P < 0.0001), symptom distress scores (Wilks lambda, 0.52; F = 10.41; P < 0.0001), and quality-of-life scores (Wilks lambda, 0.50; F = 0.50; P < 0.0001). Fatigue severity predicted survival in univariate analysis (chi-square test, 25.42; P < 0.0001). The KPS, stage of disease, and number of symptoms independently predicted survival in patients with fatigue.

CONCLUSIONS

Clinically relevant fatigue levels are correlated with symptom and quality-of-life measurements. Patients with a usual fatigue severity > 3 or a worst fatigue severity > 4 on a 1-10 scale may require further assessment.

Is Depressive Symptomatology Associated with Worse Oral Functioning and Well-being Among Older Adults?

OBJECTIVES

Although depression negatively affects individuals' physical functioning and well-being, its association with oral functioning and well-being has not been examined previously. The objective of this study was to examine the association between depressive symptomatology and oral quality of life.

METHODS

We utilized data from two samples of older adults: community-dwelling participants who used community primary care physicians in Los Angeles (n=1,653) and individuals who sought ambulatory care through four Department of Veterans Affairs facilities in the Boston metropolitan area (n=212). Depressive symptomatology was measured with the CES-D scale; Oral Quality of Life was measured with the Geriatric Oral Health Assessment Instrument and the Oral Health-related Quality of Life measure. We conducted hierarchical regression analyses to examine the effects of depression on oral quality of life, controlling for self-reported oral health, age, education, income, and marital status.

RESULTS

Individuals with more depressive symptoms reported worse oral quality of life, controlling for sociodemographic factors and self-reported oral health. This finding persisted across multiple samples and both sexes, and using two measures of oral quality of life.

CONCLUSION

These findings further emphasize the importance of treating depression among older adults, and suggest that both dentists and physicians have a role in recognizing and referring patients for such treatment.

Risk-adjusted mortality rates as a potential outcome indicator for outpatient quality assessments

OBJECTIVE

The quality of outpatient medical care is increasingly recognized as having an important impact on mortality. We examined whether a clinically credible risk adjustment methodology can be developed for outpatient quality assessments.

RESEARCH DESIGN

This study used data from the 1998 National Survey of Ambulatory Care Patients, a prospective monitoring system of outcomes of patients receiving ambulatory care in the Veterans Affairs (VA) integrated service networks.

SUBJECTS

Thirty-one thousand eight hundred twenty-three patients were followed for 18 months.

MEASURES

The main study outcome measures were observed and risk-adjusted mortality rates.

RESULTS

Of the 31,823 patients, 1559 (5%) died during the 18-months of follow-up. Observed mortality rates across the 22 VA integrated service networks varied significantly from 3.3% to 6.7% (P <0.001). Age, gender, comorbidities (Charlson Index), physical health, and mental health were significant predictors of dying. The resulting risk-adjusted mortality model performed well in cross-validated tests of discrimination (c-statistic = 0.768; 95% CI, 0.749-0.788) and calibration. Analysis of variance confirmed that the 22 integrated service networks differed in their average level of expected risk (P <0.001). Risk-adjusted rates and ranks of the networks differed considerably from unadjusted ratings.

CONCLUSIONS

Risk-adjusted mortality rates may be a useful outcome measure for assessing quality of outpatient care. We have developed a clinically credible risk adjustment model with good performance properties using sociodemographics, diagnoses, and functional status data. The resulting risk adjustment model altered assessments of the performance of the integrated service networks when compared with the unadjusted mortality rates.

Comprehensive assessment of the elderly cancer patient: the feasibility of self-report methodology

PURPOSE

Comprehensive geriatric assessment (CGA) has aided the medical community greatly in understanding the quality-of-life issues and functional needs of older patients. With its professional team assessment approach, however, CGA may be time consuming and costly. The goal of the present study was to assess the ability of cancer patients to complete a self-administered CGA and then to characterize cancer patients across multiple domains and age groups.

PATIENTS AND METHODS

Two hundred sixty-six male outpatient oncology patients at the Durham Veterans Affairs Medical Center were asked to fill out a survey assessing 10 domains (demographics, comorbid conditions, activities of daily living, functional status, pain, financial well being, social support, emotional state, spiritual well-being, and quality of life).

RESULTS

Seventy-six percent of the patients who received their surveys and kept their appointments returned the assessment tool. Older oncology patients had significantly less education (P <.0001), income (P =.05), frequent exercise (P =.01), and chance of being disease free (P =.003) than younger patients. Other findings in older patients were a higher rate of marriage (P =.02), more difficulty in taking medications (P =.05), and less cigarette (P =.03) and alcohol (P =.03) use. Members of all age cohorts reported a sense of social support, with younger patients deriving this more from family and friends than older patients, and older patients deriving social support more from membership in religious communities than younger patients. No differences were found across age groups for number and impact of comorbid illnesses, number of medications, basic and instrumental activities of daily living, pain, overall health rating, financial adequacy, anxiety, depression, and quality of life.

CONCLUSION

CGA can be conducted in an outpatient cancer community using a self-report format. Despite the fact that this population varied demographically across age groups and is limited to veterans, this study demonstrated remarkable similarities between younger and older cancer patients in terms of functional status, health states, and quality of life.

Identifying patient and physician characteristics that affect compliance with antihypertensive medications

BACKGROUND

Compliance with antihypertensive medications is essential to the clinical management of hypertension. Poor compliance with antihypertensive medications has often been associated with treatment failure and disease progression.

OBJECTIVE

To identify patient and prescriber characteristics that may influence compliance with antihypertensive medications.

METHOD

We used pharmacy records within the Veterans Health Administration, a database which included 1292 patients and 656 physicians over a 2-year time period from April 1, 1996, to April 1, 1998. The level of compliance with antihypertensive medications was assessed using a measure developed for this purpose within the Administration. Three separate ordinary least squares regression models were conducted to ascertain the effects of patient and physician characteristics on compliance.

RESULTS

Despite the importance of compliance in the clinical management of hypertension, poor compliance with antihypertensive drug treatment was still widespread. Patients who were younger and less active in their treatment decisions tended to be less compliant (P < 0.05 and 0.05, respectively). Health care providers who were older, residents in speciality care, and physicians (as compared with non-physicians) had patients who were also less likely to be compliant (P < 0.01, 0.01, and 0.05, respectively).

CONCLUSION

These findings suggest that in order to increase the effectiveness of medical care for hypertension, it is important to improve compliance with antihypertensive agents.

Quality of preventive medical care for patients with mental disorders

BACKGROUND/OBJECTIVES

This study compares quality of preventive services between persons with and without mental/substance use disorders for a national sample of medical outpatients.

RESEARCH DESIGN

Cross-sectional study.

SUBJECTS

A total of 113,505 veterans with chronic conditions and at least three general medical visits to Veterans Health Administration medical providers during 1998 to 1999.

MEASURES

Chart-derived rates of eight preventive services: two measures of immunization, four measures of cancer screening, and two of tobacco screening and counseling. Multivariable-generalized estimating equations compared rates of each preventive service among veterans with psychiatric disorders, substance use disorders, both, and neither, adjusting for demographic, health status, and facility-level characteristics.

RESULTS

On average, persons in the sample obtained 64% of the eight preventive procedures for which they were eligible. Overall rates of currency with preventive services were 58% for patients with combined psychiatric/substance use disorders, 60% and 65% for those with psychiatric and substance use disorders alone, and 66% for those with neither psychiatric nor substance use disorders. Each difference remained statistically significant in multivariable models.

CONCLUSIONS

In this sample of patients in active medical treatment, rates of preventive services were higher than rates reported for population-based, private-sector samples. Despite these high-baseline rates, persons with psychiatric disorders, particularly with comorbid substance use, were at risk for lower rate of receipt of preventive services.

Need for dental care in older veterans: assessment of patient-based measures

OBJECTIVES

There is a need for brief and accurate identification of older patients in need of dental care. This study examines the sensitivity and specificity of two screening instruments.

DESIGN

Cross-sectional study conducted in older community-dwelling male veterans.

SETTING

Four Department of Veterans Affairs (VA) clinics in greater Boston and the VA Dental Longitudinal Study (DLS).

PARTICIPANTS

Two hundred thirty-two participants from the Veterans Health Study (VHS) who were outpatients in one of four Department of Veterans Affairs clinics in greater Boston and 206 participants from the VA DLS, community-dwelling veterans who do not use VA for their health care.

MEASUREMENTS

Self-report measures included a single-item global self-report of oral health (OH-1) and a six-item dental screening measure called the D-E-N-T-A-L. The D-E-N-T-A-L queries whether participants have Dry mouth, Eating or swallowing problems, Not had a dental examination in the last 2 years, Tooth or mouth problems, Altered eating habits because of teeth or mouth, or Lesions or sores in the mouth. The criterion standard for need for treatment was determined by a clinical examination. Sensitivities and specificities were calculated and receiver operating characteristic curves plotted to identify the best cutpoints for each measure.

RESULTS

Need for care was nearly universal (97%) in the VHS and present in 64% of the DLS participants. The single-item self-report of oral health performed as well as the D-E-N-T-A-L in identifying persons in need of care. Compared with the clinical criterion, the OH-1 had a sensitivity of 0.75 and a specificity of 0.67 in identifying persons with severe need for denture care, whereas the D-E-N-T-A-L had a sensitivity of 0.80 and a specificity of 0.62 in identifying persons with severe periodontal need.

CONCLUSION

Self-reports of fair or poor oral health are useful in identifying veterans in need of dental care, especially in populations with a large number of persons who do not usually use dental care. The D-E-N-T-A-L may also be useful as a self-screening measure and community education device to encourage older persons to seek regular dental care.

Outcomes and secondary prevention strategies for male hip fractures

OBJECTIVE

To assess clinical outcomes and determine whether osteoporosis assessment and secondary prevention strategies were performed for male veterans hospitalized for hip fractures.

DESIGN

Retrospective chart review for male veterans hospitalized for hip fracture from January 1993 through July 1999.

SETTING

The Veterans Affairs Medical Center, Madison, WI.

RESULTS

Medical charts were available for 46 of 53 male patients admitted for hip fracture during the study period. Three subjects were excluded because hip fracture was associated with high-impact trauma. Mean age of the 43 study patients was 72 years (range 43-91 y), and mean length of hospitalization was 16 days (median 11 d, range 3-108 d). Thirty-two (82%) of 39 veterans whose disposition was documented were discharged to a nursing home. Eleven (26%) of 43 men died within 12 months after fracture. Twelve (28%) had fractured previously. Four (10%) subsequently had another fracture. Three of 9 patients with documented ambulation status were ambulatory at 1 year. Three patients received a bone mass measurement within a prespecified time interval of 6 months subsequent to fracture. No patient's records included a diagnosis of osteoporosis either before or within 6 months after fracture. One-third of the patients had documentation of calcium or multivitamin supplementation at discharge. One patient was receiving calcitonin at the time of fracture and continued to receive it afterward. No other patient was prescribed antiresorptive therapy by the time of hospital discharge.

CONCLUSIONS

Male veterans with hip fractures received inadequate evaluation and treatment for osteoporosis, although a substantial portion had documentation of recurrent fractures. Education of clinicians and creation of algorithms for management of established osteoporosis may improve outcomes for these individuals.

Binge drinking among female Veterans Affairs patients: prevalence and associated risks

This study evaluated the prevalence and associated risks of binge drinking, defined as having > or = 4 drinks on an occasion in the past year, in a female patient population. Of 1,259 female Veterans Affairs patients surveyed, 780 reported drinking alcohol in the past year, and 305 (24% of respondents, 39% of drinkers) reported binge drinking in the past year; 84 (11% of drinkers) had done so monthly or more often. Age-adjusted logistic regression analyses indicated that women who reported past-year binge drinking monthly or more often reported significantly increased odds of morning drinking (odds ratio [OR] = 40.3), others worrying about their drinking (OR = 38.6), arguments after drinking (OR = 13.5), hepatitis or cirrhosis (OR = 3.1), frequent injuries (OR = 2.6), smoking (OR = 3.7), drug use (OR = 22.2), and multiple sexual partners (OR = 4.6).

Posttraumatic stress disorder and the use of health services

OBJECTIVE

Prior research has demonstrated increased use of medical services among persons with anxiety and depression. This investigation examined the possible association of posttraumatic stress disorder (PTSD) with the use of nonmental health services.

METHOD

A case-comparison design enrolled 102 high users of health services and 54 low users who were assessed for PTSD diagnosis and severity of PTSD symptoms. Subjects were male veterans receiving services from the primary care clinics of the VA Boston Healthcare System during an 18-month period. Data were collected by interview by use of standardized instruments including the Clinician Administered PTSD Scale for DSM-IV, the Life Events Checklist, and the Beck Depression Inventory. Data analysis employed odds ratios, linear and logistic regression, and path analyses.

RESULTS

High users of health care were almost twice as likely as low users (27.5% vs. 14.8%) to meet diagnostic criteria for current PTSD. The two groups differed significantly on both symptom frequency and intensity. Path analyses showed an indirect positive association between PTSD and health services use, with physician-diagnosed health conditions as a mediating variable. Auxiliary analysis demonstrated that the combined mental health burden of PTSD and depression symptoms also is positively associated with number of health conditions.

CONCLUSIONS

The findings indicate that PTSD, alone and in combination with depression, has a direct negative relationship with physical health that, in turn, is associated with more frequent use of primary health care services. These results do not suggest that PTSD leads to inappropriate (eg, distress-motivated) use of services.

Reduced quality of life in veterans at risk for drug-related problems

The relationships between drug therapy and health-related quality of life in 1054 patients who received care from Department of Veterans Affairs medical centers (VAMCs) were assessed. Patients at high risk for drug-related problems were enrolled into a pharmaceutical care study at nine VAMCs. On enrollment, the short form (SF)-36 was completed and medical records were examined for evidence of coexisting illness. Drug therapy in the year before enrollment was analyzed in relation to SF-36 scores. Mean +/- SD SF-36 scores ranged from 37.99+/-41.70 for role physical to 70.78+/-18.97 for mental health domains, with all domain scores significantly below age-adjusted national norms (p<0.05). Patients taking a drug that required therapeutic monitoring had significantly lower SF-36 scores (p=0.0001 to p=0.0033) across all domains except for bodily pain and mental health, compared with patients not taking these agents.

Health status and satisfaction with health care: a longitudinal study among patients served by the Veterans Health Administration

As the Veterans Health Administration (VHA) places high priority on becoming a performance-based organization, there is an increasing need to quantify and refine its outcome measurement system. Using panel data from VHA ambulatory care patients (1996-1998), we conducted cross-lagged correlations and ordinary least squares regression to examine the relationship between 2 VHA health care values: health status and satisfaction with care. The study results indicated that patients' health status was significantly associated with their satisfaction with care, indicating that patients with better health status were more likely to be satisfied with health care. Although satisfaction with care was both a consequence and a determinant of health status, the effects of health status on satisfaction seemed to be more important than the effects of satisfaction on health status. More research is needed for a better understanding of the dynamic relationship between health status and satisfaction with care.
