Aging veterans: will they overwhelm the VA medical care system?

Treatment and survival rates of stage IV pancreatic cancer at VA hospitals: a nation-wide study

Background

Metastatic pancreatic cancer (MPC) is associated with an extremely high mortality. Current NCCN guidelines recommend systemic therapy, as it is superior to best supportive care. Undertreatment of MPC continues to be an issue. Recent treatment and survival data of MPC in Veterans' Affairs' (VA) hospitals have not been published. The relationship between MPC treatment and survival and the American College of Surgeons' (ACS) Committee on Cancer (CoC) accreditation in VA hospitals has not been studied.

Methods

Nationwide data from the National Veterans Affairs Cancer Cube Registry was analyzed. In total, 6,775 patients were diagnosed with MPC between 2000 and 2014. CoC accreditation of each VA hospital was obtained using the ACS website.

Results

MPC constitutes 52.31% of all pancreatic cancer diagnosed (6,775/12,951 cases). The near totality was men (97.44%). The above 70 years age group and the 60-70 years age group were the most common ages at diagnosis with 39.39% and 38.02% respectively. The proportion of early-onset pancreatic cancer (EOPC) was 2.84%. When compared to all stages of pancreatic cancer, stage IV pancreatic cancer had a lower proportion of cancer originating from the head of the pancreas (39.33% versus 50.63%) and more originating from the tail (17.99% versus 13.39%). Tumors originating from head of the pancreas are more likely to cause biliary symptoms and thus are more likely to be caught at an earlier stage. Overall, treatment rate in the VA at the national level with first-line chemotherapy was 37.61%. The rate of treatment over the years has increased in a linear fashion from 33.01% in 2000 to 41.95% in 2014. This has corresponded with an increase of 1-5 years survival of 9.29% in 2000 to 22.99% in 2014 and 5-10 years survival from 0.96% in 2000 to 6.00% in 2012. Treatment rates in CoC-accredited and non-CoC accredited VA hospitals were similar (38.94% and 38.12%, respectively). Survival rates in CoC-accredited and non-COC accredited VAs were similar with a 1-5 years survival rate of 8.89% and 8.57%, respectively.

Conclusions

Treatment and survival of MPC have risen significantly in the past decade at VA hospitals. CoC accreditation is not associated with a change in treatment or survival rates.

Launching Medical Foster Home Programs: Key Components to Growing This Alternative to Nursing Home Placement

Objective

The objective of this research was to examine and explain elements that enhanced or thwarted program growth of the United States Veterans Health Administration Medical Foster Home program.

Methods

This qualitative study was conducted nationally through individual interviews over the phone and in-person (n = 22) with coordinators (n = 15 at slow-growth programs; n = 6 at fast-growth programs), program support assistants (PSAs) (n = 1 at slow-growth program), and home-based primary care team members (n = 3), as well as three in-person focus groups (n = 28 total participants) with home-based primary care team members. All participants (N = 53) were involved with programs in existence for at least two years.

Results

Facilitators and barriers that enhanced or thwarted program growth emerged around four themes: A full-time coordinator; Unmitigated home-based primary care team engagement; Pursuit and receipt of appropriate referrals; and Match between caregiver, home, and Veteran.

Conclusions

To facilitate program growth, program leaders should consider themes identified and how to foster situations and shape policies that put themes into practice.

Veterans' Location in Health Professional Shortage Areas: Implications for Access to Care and Workforce Supply

OBJECTIVE

To describe the distribution of Veterans in areas of the United States where there are potentially inadequate supplies of health professionals, and to explore opportunities suggested by this distribution for fostering health workforce flexibility.

DATA SOURCES

County-level data from the 2015-2016 Health Resources and Services Administration's (HRSA's) Area Health Resources Files (AHRF) were used to estimate Veteran populations in HRSA-designated health professional shortage areas (HPSAs). This information was then linked to 2015 VA health facility information from the Department of Veterans Affairs.

STUDY DESIGN

Potential Veteran populations living in Shortage Area Counties with no VHA facilities were estimated, and the composition of these populations was explored by Census division and state.

PRINCIPAL FINDINGS

Nationwide, approximately 24 percent of all Veterans and 23 percent of Veterans enrolled in VHA health care live in Shortage Area Counties. These estimates mask considerable variation across states.

CONCLUSIONS

An examination of Veterans residing in Shortage Area Counties suggests extensive maldistribution of health services across the United States and the continued need to find ways to improve health care access for all Veterans. Effective avenues for doing so may include increasing health workforce flexibility through expansion of nurse practitioner scopes of practice.

Older Veteran Mobility: Migrant Characteristics and Use of Ambulatory Care Resources

This article focuses on the mobility of veterans who are of retirement age. An attempt is made to fit the types of moves realized by older veterans into the typology established in the existing literature. Hypotheses are tested regarding the demographic and socioeconomic characteristics of four mobility types. Additionally, the relationship between mobility and ambulatory care use is examined to determine the impact mobile veterans have on their destination resources. The results show that most sociodemographic characteristics associated with mobility types of the general elderly population are also present in the older veteran population. Interstate migrants are less likely to use outpatient services at destination than are other mobility types. Among ambulatory care users, mandatory treatment veterans, veterans who considered Department of Veterans Affairs (VA) locations in their migration decision, veterans who live within 5 miles of a VA facility, and disabled veterans had greater odds of using VA facilities.

Morbidity and mortality of gastrectomy for cancer in Department of Veterans Affairs Medical Centers

BACKGROUND

The purpose of this study was to define risk factors that predict 30-day morbidity and mortality after gastrectomy for cancer in Veterans Affairs (VA) Medical Centers.

METHODS

The VA National Surgical Quality Improvement Program prospectively collected data on 708 patients undergoing gastrectomy for cancer in 123 participating VA medical centers from 1991 to 1998. Independent variables included 68 preoperative patient characteristics and 12 intraoperative variables; the dependent variables were 21 defined adverse outcomes and death. Predictive models for 30-day morbidity and mortality were constructed by using stepwise logistic regression analysis.

RESULTS

The 30-day morbidity rate was 33.3% (236 of 708). The overall 30-day mortality rate was 7.6% (54 of 708). Significant positive predictors of morbidity (P <.05) included current pneumonia, American Society of Anesthesiologists class IV (threat to life), partially dependent functional status, dyspnea on minimal exertion, preoperative transfusion, extended operative time, and increasing age. Significant positive predictors of mortality (P <.05) included do not resuscitate status, prior stroke, intraoperative transfusion, preoperative weight loss, preoperative transfusion, and elevated preoperative alkaline phosphatase level.

CONCLUSIONS

Risk factors predicting morbidity and mortality rates at VA hospitals after gastrectomy for gastric cancer are reported by using a prospectively collected, multi-institutional database. Assigning relative weights to factors associated with adverse outcomes may help improve patient care.

Dual use of VA and non-VA primary care

OBJECTIVE

To determine how frequently veterans use non-Department of Veterans Affairs (VA) sources of care in addition to primary care provided by the VA and to assess the association of this pattern of "dual use" to patient characteristics and satisfaction with VA care.

DESIGN

Cross-sectional telephone survey of randomly selected patients from four VA medical centers.

PARTICIPANTS

Of 1,240 eligible veterans, 830 (67%) participated in the survey.

MEASUREMENTS AND MAIN RESULTS

Survey data were used to assess whether a veteran reported receiving primary care from both VA and non-VA sources of care, as well as the proportion of all primary care visits made to non-VA providers. Of 577 veterans who reported VA primary care visits, 159 (28%) also reported non-VA primary care visits. Among these dual users the mean proportion of non-VA primary care visits was 0.50. Multivariate analysis revealed that the odds of dual use were reduced for those without insurance (odds ratio [OR] 0.34; 95% confidence interval [CI] 0.18, 0.66) and with less education (OR 0.60; 95% CI 0.38, 0.92), while increased for those not satisfied with VA care (OR 2.40; 95% CI 1.40, 4.13). Among primary care dual users, the proportion of primary care visits made to non-VA providers was decreased for patients with heart disease ( p <.05) and patients with alcohol or drug dependence ( p <.05).

CONCLUSIONS

Primary care dual use was common among these veterans. Those with more education, those with any type of insurance, and those not satisfied with VA care were more likely to be dual users. Non-VA care accounted for approximately half of dual users' total primary care visits.

The Veterans Affairs medical care system: hospital and clinic utilization statistics for 1994

OBJECTIVES

The authors describe the role the Veterans Affairs (VA) medical system plays as a provider of clinic and hospital services by examining utilization levels and users' characteristics.

METHODS

The Veterans Affairs hospital discharge database, the Veterans Affairs outpatient clinic files, and the veteran population files were used to estimate the number of persons using the Veterans Affairs medical care system in 1994 and the intensity of their clinic and hospital use. Demographic and clinical characteristics of users were tabulated.

RESULTS

In 1994, 2.7 million veterans, 10.3% of all US veterans, and approximately 23% of veterans who would have met the statutory eligibility requirements for Veterans Affairs care, used the hospital and/or clinic components of the Veterans Affairs medical system. Sixty-three percent of the system's users were younger than age 65, and 10.5% were women. These 2.7 million veterans had 901,665 Veterans Affairs hospital stays, 15.5 million bed-days, and 31.2 million outpatient visits in fiscal year 1994. The average number of hospitalizations per hospital user was 1.71; the average number of visits per clinic user was 11.7. Medical, surgical, and psychiatric diagnosis-related groups (DRGs) accounted for 56%, 21%, and 23%, respectively, of hospitalizations, but psychiatric diagnosis-related groups accounted for 43% of all inpatient days. Principal medicine clinic visits and psychiatry clinic visits accounted for 21% and 16% of Veterans Affairs ambulatory care.

CONCLUSIONS

Because the patient population served by the Veterans Affairs system is skewed in a number of ways, its contribution as a provider of health services in the United States varies by gender, age, socioeconomic status, and diagnosis.

Does geriatric evaluation and management improve the health behavior of older veterans in psychological distress?

A randomized, controlled trial compared prospective 16-month health service use among 160 frail, elderly veterans receiving outpatient geriatric evaluation and management (GEM) or usual primary care (UPC). In this secondary analysis, multivariable regression was used to determine if the psychosocial assessment and support provided by the GEM team moderated the use of medical services by patients in psychological distress. The results indicate that GEM reduced outpatient use among patients who scored higher on a measure of somatization (p less than or equal to .05), but GEM increased outpatient use among patients with higher manifest anxiety (p less than or equal to .05) Psychological distress was not a factor in the use of inpatient services. GEM had a modest beneficial effect on the health behavior of frail older persons manifesting some symptoms of psychological distress.

The Whipple resection for cancer in U.S. Department of Veterans Affairs Hospitals

OBJECTIVE

The authors compiled the results after Whipple resection for cancer from a large U.S. national hospital system.

METHODS

Computerized hospital and death benefits records for patients treated with Whipple resection for cancer from 1987 to 1991 in U.S. Department of Veterans Affairs hospitals were analyzed, excluding lymphomas and neuroendocrine tumors. Institutional tumor registrar reports allowed TNM staging in 45% of these cancers.

RESULTS

Whipple resections were performed in 252 patients with pancreatic cancer and 117 with other periampullary cancers. Complications occurred in 37%, and 30-day operative mortality was 8%. Postoperative sepsis was associated with a higher operative mortality rate. In patients with staged tumors, 5-year survivors were found only in those without lymph node involvement.

CONCLUSIONS

Whipple resection can cure cancer in or near the head of the pancreas when lymph nodes are not invaded by tumor. Complications occur in nearly 40% of patients, whereas operative mortality rate is related to the average age of the patient population.

Pancreatic cancer treatment in the U.S. veteran from 1987 to 1991: effect of tumor stage on survival

To assess the outcomes after pancreatic cancer treatment in a nationwide hospital system, patients treated in Department of Veterans Affairs (DVA) hospitals from 1987 to 1991 were studied by tumor stage, the most significant reported influence on survival. Tumor registrars from DVA hospitals provided information that allowed TNM staging in 598 patients, and duration of survival from treatment to death was known in 96+% of cases. Survival was 9 months longer after 64 resections for stage I-II (localized) pancreatic cancer than after 149 other treatments (P < 0.05, ANOVA), but resection did not increase mean survival in 49 patients with stage III (lymph node metastases) disease. Twenty-one patients with ampullary, duodenal, bile duct, or cystic cancers had a significantly increased survival at any stage, but this may be due to the selection of sicker patients for nonoperative therapies.

Dental care use by U.S. veterans eligible for VA care

Military veterans eligible for dental care in U.S. Department of Veterans Affairs (VA) facilities cooperated for a mailed survey about their dental care utilization. Subjects were selected because of their eligibility for continuing dental care in VA facilities at no monetary cost. However, only 48% reported the VA as their only or primary source of dental care; this allowed us the opportunity to compare dental care frequency by those who received dental care at no monetary cost with those who did not, as well as measure delivery system effects on dental care use. Consequently, we tested respondent-level and delivery system-level hypotheses regarding determinants of veterans' dental care use. Predisposing characteristics (dentate status, usual reason for dental visits, and the importance placed on dental care and oral health) were the strongest determinants of interval since last dental visit. Enabling determinants (current source of dental care, and having a regular source of care) were also significant, but measures of need for dental care (perceived oral health and perceived need for treatment) were not. More recent dental care use by veterans who used the VA delivery system as their source of dental care, even with dental care payment source and other determinants accounted for, suggests that the VA delivery system may have promoted more regular use compared to other systems.

Eligible veterans' choice between VA-covered and non-VA-covered dental care

Veterans who were eligible for dental care in Department of Veterans Affairs (VA) facilities at no monetary cost responded to a mailed questionnaire. Seventy-one percent were aware that they were actually eligible for VA dental care. However, only 48 percent reported the VA as their only or primary source of dental care. Eligibility status, perceived quality of VA dental care, use of VA medical care, perception that one's income meets expenses, and perceived need for dental care were significant correlates of using the VA as one's current source of dental care. Level of formal education, perception that one's income meets expenses, transportation pattern, geographic distance from a VA facility, and eligibility status were significant correlates of using the VA as one's current medical care source. Research on VA utilization offers the opportunity to study issues of access to, and use of, a large public health care system whose patients largely receive care at no monetary cost. Veterans' use of VA dental and medical care is apparently influenced by a wide variety of factors, ranging from barriers to access to non-VA systems, to characteristics of the VA delivery system itself, to need for treatment.

Geographic differences in the use of Veterans Administration hospitals

This study contrasts the determinants of community hospital utilization with Veterans Administration (VA) hospital utilization using traditional planning variables. The comparisons had some expected and some unanticipated findings. Regional differences in non-VA hospital admissions and bed days are fairly well explained by measures of medical need, provider supply, community alternatives, and sociodemographic characteristics (other than those used as proxies for case mix). However, regional variations in the VA are explained less well by the same classes of variables and the unexplained differences between the two systems do not correspond geographically. This suggests that the two systems have different reasons for regional variation. Further, contrary to expectation, when other predictors are held constant, excess bed capacity in the area does not correlate with lower VA utilization. The study is important as the VA comes under increasing pressure to contain costs. It may well be that the rational planning model attributed to the public sector is less likely to overcome maldistribution than the private sector 'invisible hand'. Policy analysts need to give more attention to the political, bureaucratic determinants of resource allocation before changing eligibility criteria or merging the two systems.

Patient characteristics and eligibility in a Veterans Administration ambulatory care triage clinic

We surveyed 5,225 consecutive patients presenting to a Veterans Administration (VA) Ambulatory Care Triage Clinic to ascertain the characteristics of patients and to assess the role of eligibility in determining disposition from triage. Most patients (66 per cent) had non-service connected (low eligibility) conditions and had no health insurance (64 per cent). Lack of service connected priority (high eligibility) did not influence access to hospitalization (8.3 per cent) or longitudinal outpatient care (24.5 per cent). The study suggests that veterans with no health insurance, with low eligibility for VA service, use the VA triage clinic for episodic medical care.

Herniorrhaphy in the elderly. Benefits of a clinic for the treatment of external abdominal wall hernias

Elective abdominal herniorrhaphy carries morbidity and mortality rates of 26 percent and 1.5 percent, respectively, in patients over 65 years of age. These figures climb to 55 percent and 15 percent during emergent surgery. Our purpose was to investigate if standardization of treatment could improve such results. Our program stressed centralization of care in a hernia clinic; early operation of patients at risk of incarceration; optimization of underlying systemic disorders by consultative services; operation under local anesthesia; preoperative, operative, and postoperative protocol; and continuity of care by senior personnel. Over a 4 year period, we have performed 241 abdominal herniorrhaphies in patients over 65 years of age (median age 71.5 years old) who exhibited an 84 percent incidence of significant preoperative systemic disorders. Since the inception of our program, our rate of emergent operation has decreased significantly from 7 percent to 2 percent (chi-square less than or equal to 0.05). Our rate of systemic complications after elective operation was 1.2 percent and 0 after emergent operation. These data are statistically better than those reported in the literature (chi-square less than or equal to 0.05). These results suggest that the creation of a hernia clinic significantly improves the care of herniated patients.
