Gender disparities in Veterans Health Administration care: importance of accounting for veteran status

BACKGROUND: In an effort to assess and reduce gender-related quality gaps, the Veterans Health Administration (VHA) has promoted gender-based research. Historically, such appraisals have often relied on secondary databases, with little attention to methodological implications of the fact that VHA provides care to some nonveteran patients. OBJECTIVES: To determine whether conclusions about gender differences in utilization and cost of VHA care change after accounting for veteran status. DESIGN: Cross-sectional. SUBJECTS: All users of VHA in 2002 (N = 4,429,414). MEASURES: Veteran status, outpatient/inpatient utilization and cost, from centralized 2002 administrative files. RESULTS: Nonveterans accounted for 50.7% of women (the majority employees) but only 3.0% of men. Among all users, outpatient and inpatient utilization and cost were far lower in women than in men, but in the veteran subgroup these differences decreased substantially or, in the case of use and cost of outpatient care, reversed. Utilization and cost were very low among women employees; women spouses of fully disabled veterans had utilization and costs similar to those of women veterans. CONCLUSIONS: By gender, nonveterans represent a higher proportion of women than of men in VHA, and some large nonveteran groups have low utilization and costs; therefore, conclusions about gender disparities change substantially when veteran status is taken into account. Researchers seeking to characterize gender disparities in VHA care should address this methodological issue, to minimize risk of underestimating health care needs of women veterans and other women eligible for primary care services.     

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

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

Racial/ethnic differences in diabetes care for older veterans: accounting for dual health system use changes conclusions

BACKGROUND: Veterans Health Administration (VHA) databases are used extensively to study racial/ethnic disparities; however, these databases may not capture all care received by VHA patients. OBJECTIVES: We examined the extent to which accounting for non-VHA care changed conclusions about racial/ethnic disparities for VHA patients with diabetes. METHODS: Using a cross-sectional observational study, we analyzed a national sample of noninstitutionalized Hispanic (n = 5931), black (n = 24,670), and white (n = 149,222) VHA patients with diabetes who were at least 65 years of age for receipt of annual HbA1c testing, low-density lipoprotein (LDL) cholesterol testing, or eye examination from VHA and Medicare administrative files. RESULTS: In VHA alone data, adjusting for patient characteristics, Hispanic and black patients were as likely as white patients to receive HbA1c testing (odds ratio 1.06 [95% confidence interval 0.99-1.13] and 1.04 [1.00-1.07], respectively), and more likely to receive eye examinations (1.31 [1.24-1.38] and 1.33 [1.29-1.37], respectively). Hispanic patients were equally likely (1.01 [0.95-1.07]) and black patients were less likely (0.81 [0.79-0.84]) to receive LDL testing versus white patients. In VHA plus Medicare data, Hispanic and black patients were less likely than white patients to receive HbA1c (0.76 [0.71-0.82] and 0.83 [0.80-0.87], respectively) and LDL testing (0.84 [0.79-0.90] and 0.70 [0.68-0.72], respectively), and equally likely to receive eye examinations (0.91 [0.86-0.96]) and 0.98 [0.95-1.01]), respectively). Accounting for VHA facility had little effect on results. CONCLUSIONS: Restricting to VHA data masks racial/ethnic disparities in care of VHA patients. VHA researchers must be aware and supplement VHA data with other sources whenever possible.     

Severe Pain in Veterans: The Effect of Age and Sex,and Comparisons With the General Population

This study provides national prevalence estimates of US military veterans with severe pain, and compares veterans with nonveterans of similar age and sex. Data used are from the 2010 to 2014 National Health Interview Survey on 67,696 adults who completed the Adult Functioning and Disability Supplement. Participants with severe pain were identified using a validated pain severity coding system imbedded in the National Health Interview Survey Adult Functioning and Disability Supplement. It was estimated that 65.5% of US military veterans reported pain in the previous 3 months, with 9.1% classified as having severe pain. Compared with veterans, fewer nonveterans reported any pain (56.4%) or severe pain (6.4%). Whereas veterans aged 18 to 39 years had significantly higher prevalence rates for severe pain (7.8%) than did similar-aged nonveterans (3.2%), veterans age 70 years or older were less likely to report severe pain (7.1%) than nonveterans (9.6%). Male veterans (9.0%) were more likely to report severe pain than male nonveterans (4.7%); however, no statistically significant difference was seen between the 2 female groups. The prevalence of severe pain was significantly higher in veterans with back pain (21.6%), jaw pain (37.5%), severe headaches or migraine (26.4%), and neck pain (27.7%) than in nonveterans with these conditions (respectively: 16.7%, 22.9%, 15.9%, and 21.4%). Although veterans (43.6%) were more likely than nonveterans (31.5%) to have joint pain, no difference was seen in the prevalence of severe pain associated with this condition.

Audiometric thresholds and prevalence of tinnitus among male veterans in the United States: data from the National Health and Nutrition Examination Survey, 1999-2006

Hearing loss and tinnitus are the two most prevalent service-connected disabilities among U.S. veterans. The number of veterans receiving compensation and services from the Department of Veterans Affairs (VA) for these conditions continues to increase annually. However, the majority of veterans in the United States do not use VA medical centers or clinics for healthcare and do not receive VA compensation payments. Therefore, the prevalence of hearing loss and tinnitus among U.S. veterans is unknown. This study used National Health and Nutrition Examination Survey data to estimate the prevalence of these auditory conditions among male veterans. Between 1999 and 2006, pure tone audiometric data collected from 845 male veterans were compared with pure tone thresholds collected from 2,086 male nonveterans. We used questionnaire data collected between 1999 and 2004 to calculate and compare the prevalence of tinnitus for 2,174 veterans and 4,995 nonveterans. In general, pure tone thresholds did not differ significantly between veterans and nonveterans for most frequencies tested (500-8,000 Hz). The overall prevalence of tinnitus was greater for veterans than that for nonveterans (p < 0.001), with statistically significant differences in the 50 to 59 and 60 to 69 age groups.     

Associations between alcohol-related concerns,normative perceptions of peer alcohol use,and veterans’ drinking behavior over six months

Abstract

The Veterans Health Administration (VHA) has implemented initiatives to increase rates of brief alcohol counseling (BAC). Half of eligible veterans do not receive such care. Understanding patient characteristics associated with drinking behavior may identify patients for whom BAC may be acceptable. Data collected from veterans between January 2010 and September 2011 (N?=?167) were examined. Results find that alcohol-related concerns and perceptions of peer alcohol consumption are associated with reduced drinking behavior. These findings suggests that assessing drinking concerns and perceptions of peer alcohol use may help to identify patients interested in changing drinking behavior, receiving care, and assist providers in delivering appropriate counseling.     

Factors influencing receipt of outpatient rehabilitation services among veterans following lower extremity amputation

Zhou J, Bates BE, Kurichi JE, Kwong PL, Xie D, Stineman MG. Factors influencing receipt of outpatient rehabilitation services among veterans following lower extremity amputation.

Objective

To determine patient-, treatment-, and facility-level characteristics associated with receiving outpatient rehabilitation services after lower extremity amputation within the Veterans Affairs (VA) system.

Design

Observational study.

Setting

All Veterans Affairs Medical Centers (VAMCs).

Participants

Veterans (N=4165) with lower extremity amputation discharged from VAMCs between October 1, 2002, and September 20, 2004.

Interventions

Not applicable.

Main Outcome Measures

Receipt of outpatient rehabilitation services up to 1 year postdischarge. A Cox proportional hazards model was used to determine the adjusted hazard ratio and 95% confidence interval of veterans to receive outpatient services.

Results

Sixty-five percent of veterans with lower extremity amputation received outpatient services. Older veterans, patients admitted for surgical amputation from extended care rather than transferred from another hospital, and those with transfemoral and/or bilateral rather than unilateral transtibial amputations were less likely to receive outpatient services. Those with serious comorbidities and those who had procedures for acute central nervous system disorders, active cardiac pathology, serious nutritional compromise, and severe renal disease during the surgical hospitalization less often initiated outpatient care. Patients who received inpatient consultative rehabilitation compared with inpatient specialized rehabilitation, and who were treated in the Northeast compared with the Southeast less often initiated outpatient care. Finally, those discharged to home or other locations rather than extended care had an initial increased likelihood of receiving outpatient service, but by 180 days postdischarge those discharged to extended care were more likely to initiate outpatient services.

Conclusions

Both clinical characteristics and types of rehabilitation services received appear to influence the receipt of outpatient rehabilitation services. Geographic location also affected the receipt of outpatient rehabilitation, suggesting that care patterns are not standardized across the nation.     

Veterans' reports of pain and associations with ratings of health, health-risk behaviors, affective distress, and use of the healthcare system

The improved management of pain among veterans seeking care in Veterans Health Administration (VHA) facilities has been established as a priority. This study documents the high prevalence of reports of pain among a convenience sample of 685 veterans seeking care in a VHA primary care setting. Also reported are associations of pain complaints with self-rated health, an index of emotional distress, health-risk behaviors such as tobacco and alcohol use, health-related concerns about diet and weight, and perceptions of the availability of social support. The relationship between the presence of pain and use of outpatient and inpatient medical and mental health services is also examined. Nearly 50% of the sample reported that they experience pain regularly and that they were concerned about this problem at the time of the index visit to their primary care provider. Persons acknowledging the presence of pain, relative to those not reporting pain, were younger, reported worsening health over the past year, had greater emotional distress, used tobacco, had diet and/or weight concerns, and were found to use more outpatient medical, but not inpatient medical or mental health services. Results support the goals of the VHA National Pain Management Strategy designed to reduce unnecessary pain and suffering among veterans receiving care in VHA facilities.     

Veterans' and nonveterans' use of health services. A comparative analysis

This study compares the use of health services by veterans with that by nonveterans; compares the use of health services by veterans from different service cohorts with each other; and examines the correlates of veterans' use of the VA health care delivery system. After adjusting for differences in the predisposing, enabling, and need characteristics, there were virtually no meaningful differences in the use of health services between veterans and nonveterans. This suggests that health care planning within the VA can proceed similarly to health care planning for the civilian population, albeit taking into consideration the significant difference in the sex distribution between the two populations. Virtually no meaningful or consistent veteran cohort effects on the use of health services were found. This suggests that health care planning within the VA may proceed without regard to changes in the nature of the veteran cohort structure. Finally, although there was a strong and obvious effect of service-connected disabilities (high-priority eligibility due to health status) on the use of the VA health care delivery system for veterans, there was no effect of being 65 years of age and older (high-priority eligibility due to age) on the use of the VA. Aside from service-connected disabilities, limited access to other health care delivery systems was the major factor behind the demand for VA care.     

Falls requiring medical attention among veterans with multiple sclerosis: a cohort study

The purpose of this study was to estimate the relative risk of an injurious fall requiring medical attention in veterans with multiple sclerosis (MS) compared with veterans without MS after controlling for sex, age, and healthcare use. The sample included 195,417 veterans treated at Veterans Health Administration (VHA) facilities in the Northwest United States in fiscal year 2008. We obtained information regarding MS diagnosis, injurious falls (operationalized as International Classifi cation of Diseases-9th Revision-Clinical Modification codes E880-E888), and demographic and healthcare use data from the VHA Consumer Health Information Performance Set database. Using logistic regression, we determined the adjusted odds ratio (OR) of an injurious fall to be three times higher in female veterans with MS than in female veterans without MS (OR = 3.0, 95% confidence interval [CI] = 1.6-5.5). The adjusted OR of an injurious fall for men with MS was also higher than for men without MS, but this difference was not statistically significant (OR = 1.2, 95% CI = 0.8-2.1). We recommend further studies evaluating the medical, social, and economic consequences of injurious falls, as well as interventions to prevent injurious falls, to improve the independence and quality of life of veterans and others living with MS.     

Directed rehabilitation reduces pain and depression while increasing independence and satisfaction with life for patients with paraplegia due to epidural metastatic spinal cord compression

We determined whether directed rehabilitation affected survival, pain, depression, independence, and satisfaction with life for veterans who were nonambulatory after spinal epidural metastasis (SEM) treatment. We compared 12 consecutive paraplegic veterans who received 2 weeks of directed rehabilitation with a historical control group of 30 paraplegic veterans who did not receive rehabilitation. The rehabilitation program emphasized transfers, bowel and bladder care, incentive spirometry, nutrition, and skin care. The outcome measures were survival, independence, pain levels, depression, and satisfaction with life. Patients receiving rehabilitation had longer median survivals, fewer deaths from myelopathic complications, less pain 2 weeks after SEM treatment, lower depression scores, and higher satisfaction with life scores. In addition, among the patients who received rehabilitation, eight became independent for transfers (vs zero controls) and nine returned home (vs six controls). We conclude that directed rehabilitation reduced patients' pain levels and increased their mobility, survival, and life satisfaction.     

Complementary and alternative medicine use in veterans with multiple sclerosis: Prevalence and demographic associations

The present study explored complementary and alternative medicine (CAM) use in veterans with multiple sclerosis (MS). We administered self-report questionnaires to 451 veterans who received healthcare from Veterans Health Administration facilities. CAM use among veterans with MS was widespread; 37% of respondents reported current or past use. Roughly 33% of CAM users reported using multiple interventions, and 40% of respondents desired interventions that they were not already using. Logistic regression suggested that CAM use was more likely among participants with graduate-level education, poor self-reported health over the past year, and a progressive relapsing MS subtype. Participants who used traditional medical services were also more likely to use CAM, which suggests that CAM services are used in addition to, as opposed to in place of, traditional services. As others have proposed, these results suggest that care providers who work with persons with MS would be well served to understand, routinely screen for, and make use of CAM when appropriate.     

Rediscovering the patient's role in receiving health promotion services

OBJECTIVE: This study examined differences in the odds of receiving health promotion/disease prevention services recommended by the US Preventive Services Task Force among three subgroups of patients. It tested the hypotheses that those most uninvolved in their own health (as exemplified by the lack of knowledge of blood pressure and cholesterol levels despite having been tested) would receive the least other health promotion services, and those being treated for both high blood pressure and hyperlipidemia would receive the most additional services. METHODS: A mail survey was sent to a random sample of 68,422 veterans who had obtained primary care from any of the 153 Veterans Health Administration facilities in 1996. The adjusted response rate was 68%. Subgroup analyses were performed on three subgroups who reported having been tested for both hypertension and hyperlipidemia in the previous year (n = 5,113). RESULTS: Both hypotheses were supported. Uninvolved patients were the least likely subgroup to report obtaining other recommended health promotion services, and the dually treated were most likely. The uninvolved subgroup was significantly more likely to report being female, physically inactive, current smokers, and heavy alcohol drinkers, and to report having a problem with alcohol, and significantly less likely to report being > or =50 years of age and overweight, to almost always wear seat belts, and to obtain at least 90% of their health care at the Veterans Health Administration. CONCLUSIONS: Clinicians need to encourage all patients to receive health promotion services, but in particular they should be aware that those who do not know their last hypertension and cholesterol levels despite having been tested are particularly in need of attention.     

Lipid testing among patients with diabetes who receive diabetes care from primary care physicians

OBJECTIVE: To identify factors related to lipid testing among patients with diabetes who receive diabetes care from primary care physicians. RESEARCH DESIGN AND METHODS: North Carolina Medicare claims were used to identify individuals with diabetes who received diabetes care from primary care physicians. Lipid testing was related to sociodemographic characteristics, comorbid conditions, physician specialty, and mortality. RESULTS: Based on Medicare claims from July 1997 through June 1999, 13,660 diabetic North Carolina residents with Medicare, 65-75 years of age, had received HbA(1c) testing from a single primary care physician during at least three of four consecutive 6-month time intervals. During these 2 years, 31% had no lipid profile and 24% had only one lipid profile. Caucasians were 1.6 times more likely than African Americans to receive lipid profiles. Patients not receiving state Medicare assistance were 1.4 times more likely to have a lipid profile than the presumably lower-income patients receiving assistance. Patients with stroke and heart failure were less likely to receive lipid profiles. Those with no lipid profile were almost twice as likely to die from cardiovascular disease than those with at least two lipid profiles. CONCLUSIONS: Adherence to lipid testing recommendations by primary care physicians for elderly patients with diabetes has much room for improvement. The most vulnerable patients (African Americans, the economically disadvantaged, and the medically complex) are the least likely to receive lipid testing.     

Drugs and falls in community-dwelling older people: a national veterans study

OBJECTIVE: The aim of this study was to identify which specific medications within recognized major problematic drug categories that increase risk of falling were prescribed to veterans before their out-patient treatment for a fall. METHODS: This was a retrospective, cross-sectional national secondary outpatient data analysis with an age- and sex-matched comparison group. The setting was the national Veterans Health Administration (VHA) ambulatory health care system in fiscal year (FY) 2004. The study population was VHA patients aged>or=65 years who had fall-related outpatient clinical health care encounters in FY 2004 (as indicated by diagnostic codes) and who received >or=1 outpatient medication during the study period. The age- and sex-matched comparison group consisted of an equal number of patients with nonspecific chest pain. The percentage of patients in each group receiving medications (at the time of the outpatient encounter) that affect the cardiovascular system (CVS), central nervous system (CNS), or musculoskeletal system (MSS) was compared with Bonferrom-adjusted P values. RESULTS: The study sample consisted of 20,551 patients; the comparison group included the same number of patients. More patients with fall-coded encounters used CNS drugs than those with nonspecific chest pain (42.05% vs 29.29%). Also, within the CNS category, more patients with fall-coded encounters used antiparkinsonian medications (3.67% vs 1.32%), Alzheimer's disease medications (ie, cholinesterase inhibitors [5.40% vs 2.35%]), anticonvulsants/barbiturates (8.95% vs 5.18%), antidepressants (22.50% vs 14.16%), antipsychotics (4.68% vs 2.01%), opioid analgesics and narcotics (11.21% vs 9.09%), and benzodiazepines (7.60% vs 5.96%) (all, P<0.002). More patients with nonspecific chest pain received CVS drugs compared with the fall-coded group (69.13% vs 63.07%; P<0.002). Within the CVS category, more patients in the nonspecific chest pain group received angiotensin-II receptor antagonists, angiotensin-converting enzyme inhibitors, beta-blockers, calcium channel blockers, vasodilators, diuretics, and antiarrhythmics (all, P<0.002). No differences were noted between groups in the MSS category, except for NSAIDs, which more patients in the nonspecific chest pain group used than in the fall-coded group (6.44% vs 5.63%; P<0.002). CONCLUSION: In this study, subjects with a health care encounter for a fall (as indicated by diagnostic code) were prescribed significantly more CNS-category medications than subjects in the age- and sex-matched comparison group.
