A Population-Based, Cross-Sectional Study Examining Health Services Deficits of US Veterans Using 2014 Behavioral Risk Factor Surveillance System Data: Is Rural Residency an Independent Risk Factor after Controlling for Multiple Covariates?

Abstract

Introduction: In 2014, it was reported that there was a backlog of an estimated 1.2 million claims nationwide at the United States Veterans Administration (VA). This ecological occurrence opened up a space for asking and answering some important questions about health service deficits (HSD) of US veterans, which is the focus of the research reported on in this paper. The purpose of this study was to ascertain if rural veterans were more likely to experience HSDs than urban military veterans after controlling for a number of covariates. Methods: Bivariate and multivariate data analysis strategies were used to examine 2014 Behavioral Risk Factor Surveillance System (BRFSS) survey data. HSD was the dependent variable. Results: Two multivariate models were tested. The first logistic regression analysis yielded that rural veterans had higher odds of having at least one HSD. The second yielded that rural US veterans in 2014 who had higher odds of having at least one HSD were: 18–64 years of age, unemployed seeking employment, living in households with annual incomes lower than $75,000, without a university degree, not part of a married or unmarried couple, a current smoker, and/or a binge drinker within the last 30 days. Conclusions: The study described here fills identified epidemiological gaps in our knowledge regarding rural US military veterans and HSDs. The findings are not only interesting but important, and should be used to inform interventions to reduce HSDs for rural veterans.

1. Introduction

Since 1990, the United States (US) has engaged in multiple major conflicts at distinct periods of time. Starting in 1990, the US was involved in the first Gulf War, termed Operation Desert Storm [1]. A decade later, in 2001, the US began its most recent involvement in the Middle East with the invasion of Afghanistan in Operation Enduring Freedom (OEF) [1] and later in 2003 in Iraq in Operation Iraqi Freedom (OIF) [1]. The first phase of Operation Enduring Freedom ended in 2014; however, the US remains involved in Afghanistan as part of a North American Treaty Organization (NATO) led initiative. Presently, more than 1.6 million American men and women have served or are currently serving in support of the NATO Afghanistan initiative, OEF, and OIF [2,3].

In 2014, it was reported that there was a backlog of an estimated 1.2 million claims nationwide at the United States Veterans Administration (VA) [4]. Moreover, wait times to be seen by a healthcare provider extended well past the legislated 30 days [5]. Few would deny that the VA has long struggled to cope with claims of all sorts [6]. The backlog reported, however, had been amplified as more soldiers needing a wide array of healthcare returned from Iraq and Afghanistan [7]. Since 2014 there has been considerable press coverage regarding the manner in which the VA has either managed or mismanaged their claims backlog. This ecological occurrence has opened up a space for asking and answering some important questions about health service deficits (HSD) of US veterans, which is the focus of the research reported on in this paper.

HSD [8,9,10] is an evolving concept and is composed of the following: no routine medical exam, no primary care provider, no health insurance, and/or deferring medical care because of cost; if one at least one of these has been experienced within the last 12 months, this constitutes having an HSD [8,9,10]. These four factors represent HSDs in part because of their direct connection to preventive care and/or access to care. In the US, health insurance is very often a determinant of healthcare access, just as having the financial means for the co-pay portion of care or out-of-pocket charges for healthcare. Annual or routine check-ups and/or having a personal healthcare provider are essential for the receipt of preventive care in the US.

An earlier study [4], analyzing Behavioral Risk Factor Surveillance System (BRFSS) data, examined depression and HSDs in rural compared to non-rural adult populations and found that rural residency was an independent risk factor for greater HSDs in adults with depression. [8] In 2014, a study was published examining the prevalence of HSDs in depressed (determined by a standardized and validated measure) US veterans [11]. Rural residency was found to be an independent risk factor for greater odds of having a HSD in rural veterans. HSDs have also been examined in adults with asthma [10] as well as arthritis [9], with rural geographic locale found to be significantly associated with HSDs in those populations.

In the US, a higher per capita proportion of military veterans come from rural rather than non-rural communities [12]. US military veterans, if discharged or released under conditions other than dishonorable, are eligible to receive healthcare benefits through the Veterans Health Administration (VA). The VA is the US’s largest integrated healthcare system and has defined criteria for the priority of healthcare services for eligible veterans. These priority categories favor military service-related injuries and illnesses [1,2,3,4,5].

Access to care has often been noted as an issue in rural communities for both veterans and non-veterans [13]. The VA has made efforts to expand services to rural areas to ensure adequate access [1,14]. Moreover, in the past decade, greater attention has been paid to veterans’ mental health issues as a direct result of their wartime deployment [2], and subsequent changes in mental health status [2]. For instance, there has been a documented increase in depression, [15,16] post-traumatic stress disorder (PTSD) [17], alcohol and substance abuse [15], and suicide [18] among US military veterans. In response to these emergent issues, the VA has increased mental health staffing [19] and has implemented evidence-based models of integrated mental health services in outpatient clinics [14]. As important as mental healthcare is for veterans, especially for those returning from combat, healthcare for other health-related issues are equally important since these health conditions impact their quality of life. We believe that an assessment of HSDs is necessary for all veterans.

The purpose of this study was to ascertain if rural veterans were more likely to experience HSDs than urban military veterans after controlling for a number of covariates. The study described here sought to fill identified epidemiological gaps in our knowledge regarding rural US military veterans and HSDs. Among the epidemiological gaps are whether or not rural veterans have greater odds of experiencing HSDs in comparison to urban veterans. Furthermore, we do not know if the VA has successfully bridged healthcare access disparities for rural veterans, reducing the possibility of HSDs as we have defined them. Analyzing population-based, non-VA, non-medical records or data for veterans might better identify the population of US military veterans (by specific characteristics) who may have HSDs, thus providing direction for health systems interventions aimed at solutions for reducing HSDs.

2. Methods

To answer the research question, 2014 BRFSS data were analyzed using bivariate and multivariate techniques. BRFSS is a random digit telephone survey that is a collaborative project of the Centers for Disease Control and Prevention (CDC) and all US states and territories. The survey measures several behavioral risk factors and disease states in the non-institutionalized US adult population aged 18 through 99 years. A complex multi-stage sampling approach is used by BRFSS and subsequently a weighting factor is calculated for application to the data in order to ensure that they are representative of the US population based on the most recent census data. A more in-depth description of the data weighting process can be found elsewhere [20].

BRFSS collects information from individuals on health risk behaviors, preventive health practices, chronic conditions, and healthcare access primarily related to chronic disease and injury. BRFSS is composed of core questions that must be asked of every survey participant, as well as optional modules that may be chosen by individual states and asked only of the survey respondents from the participating state(s). To identify veterans for this study, responses to the question: Are You a Veteran? were used. All respondents selecting yes were considered military veterans.

For analysis, a number of variables were either re-coded or computed. Re-coding for the most part entailed collapsing response categories and removing the response categories of don’t know and refused. Re-coded variables were: age, employment status, marital status, deferment of medical care within the past year because of cost, timing of last routine medical check-up, health insurance status, personal healthcare provider, education attained, annual household income, binge drinking, smoking status, body mass index (BMI), arthritis, depression in lifetime, diabetes, and geographic locale. All variable re-codes were undertaken for clarity of factors for analysis and ease of interpretation. For instance, in BRFSS, marital status has nine categories. These were re-coded into two categories: Married or Part of Unmarried Couple, and Not Married or Part of Unmarried Couple, because these two categories encapsulate the concepts of interest. Likewise, education had nine original categories that were reduced to three through re-coding. The re-coded categories represent the most meaningful ones for this analysis. Age was re-coded into two categories: 18–64 years of age and 65 years and older. This re-code was purposive, since in the US persons 65 years of age and older are covered by Medicare regardless of their military status.

The geographic locale variable was determined using the metropolitan statistical area (MSA) variable provided in the BRFSS database. MSA is comprised of geographic entities delineated by the Office of Management and Budget (OMB) for use by Federal statistical agencies in collecting, tabulating, and publishing federal statistics. The MSA variable was recoded into the dichotomous categories of rural and urban. Rural veterans were defined as people living either within an MSA that had no center city or outside an MSA. Urban veterans included all respondents living in a center city of an MSA, outside the center city of an MSA but inside the county containing the center city, or inside a suburban county of an MSA.

Three variables were computed from other variables in the BRFSS database. These were race/ethnicity, chronic disease, and HSDs. Race/ethnicity was calculated from participant responses to two separate survey questions—one regarding race and the other regarding Latino/Hispanic ethnicity. All race/ethnicity categories were computed as mutually exclusive entities. For example, all respondents coded as Caucasian chose white as their racial classification, likewise, black for African American, etc. If a respondent identified themselves as Hispanic or Latino they were classified by that ethnic category regardless of any additional racial classification. The category of Other/Multiracial was also calculated.

The chronic disease variable was a composite variable calculated from factors from four separate variables—have arthritis, have diabetes, have lifetime depression, and obesity, as measured by the calculated BMI. These were chosen because they are common and age prevalent. Having at least one of these conditions was coded as at least one chronic condition, although this did not preclude respondents from having more than one of these chronic conditions.

As mentioned in the introduction, the variable HSD was computed from the factors of four different variables: no routine medical exam, no primary care provider, no health insurance, and/or deferring medical care because of cost, all within the last 12 months. Having at least one of these was coded as at least one HSD; this did not preclude respondents from having more than one of these. The variable HSD was the dependent variable for the study.

For bivariate analysis, since all of the independent variables were categorical, either a chi square or an odds ratio was computed as the test statistic. For the multivariate analyses performed, an adjusted odds ratio was the calculated test statistic. All analyses were performed on weighted data as is recommended by the CDC. The weighting, calculated by the CDC, uses the most recently available census data to provide a stratified representation of the nation’s non-institutionalized population. Only findings from weighted analyses were considered valid. All analyses were performed using SPSS version 24 (IBM, Chicago, IL, USA) with alpha set at p < 0.05. The Institutional Review Boards (IRBs) of the researchers’ institutions recognize that the analysis of de-identified, publicly available data does not constitute human subjects research as defined in federal regulations, and as such does not require IRB review. Human subjects review was not sought nor received.

displays the study variables data describing US veterans as of 2014. Descriptive analysis yielded that in 2014, 20% of US veterans lived in rural geographic locales, 91% were males, and 81% were between the ages of 18 and 64 years. An estimated 26% were university graduates with at least a four-year degree, 47% were employed for wages, and 65% were either married or part of an unmarried couple. While 81% self-reported their health as good to excellent, 61% had at least one chronic disease. Binge drinking in the past 30 days was reported by 15% of veterans, while 18% reported being current smokers.

displays the bivariate analysis of all 12 independent variables or covariates (age, sex, race/ethnicity, employment status, marital status, education attained, annual household income, employment status binge drinking, smoking status, chronic disease, and geographic locale) by the study dependent variable—HSD. All of the covariates were categorical. For covariates with more than two factors, a chi square test for significance was calculated. For bifurcated covariates, odds ratios were used as the test statistic. Bivariate analysis revealed that each of the covariates had a statistically significant relationship with the dependent variable. Given these results, all of the independent variables were entered into the multivariate model tested.

. The population for this model was all US veterans in 2014. All reference (comparison) categories are indicated in the table. Logistic regression analysis yielded that rural veterans had higher odds of having at least one HSD. This was also the case for Hispanic veterans, those reporting other/multirace/ethnicity, aged ≤64 years, earning <$75,000, less educated (<high school or at least high school), not married or coupled, current smokers, and binge drinkers. Also, adult veterans with no chronic disease had higher odds of having at least one HSD. Female sex and African American race were protective from at least one HSD.

presents the results of the second multivariate model tested. All reference (comparison) categories are indicated in the table. The logistic regression analysis of rural US veterans in 2014 revealed that those who had higher odds of having at least one HSD were: 18–64 years of age, unemployed seeking employment, living in households with annual incomes lower than $75,000, without a university degree, not part of a married or unmarried couple, a current smoker, and/or a binge drinker within the last 30 days. Being female or African American was protective against having at least one HSD.

4. Discussion

This study sought to ascertain if the geographic locale of US veterans impacted their odds of experiencing at least one HSD. More specifically, we were interested in determining if rural residency of veterans was an independent risk factor for HSDs after controlling for a number of possibly contributing covariates. A number of notable findings emerged from this study, the first of which was that rural veterans had higher odds of having at least one HSD when compared to their urban counterparts. Furthermore, our results yielded that rural veterans ages 18 to 64 had greater odds of experiencing at least one HSD. This second finding was not dissimilar to that regarding all US veterans regardless of geographic locale. Our results also revealed that rural veterans with incomes less than $35,000 also had greater odds of experiencing at least one HSD, as did those without a university degree. Rural veterans who were current smokers and who were binge drinkers in the past 30 days also had higher odds of having at least one HSD.

These findings provide an epidemiological snapshot of rural US veterans experiencing at least one health service deficit in 2014. HSDs are not a small issue, given the difficulties of the VA in processing claims and providing healthcare for veterans that came to a head in 2014 [21]. Rural residency emerged as an independent risk factor for HSDs for veterans. Recent research has established that rural residency is an independent risk factor for adverse health-related issues for a number of specific diseases and conditions separate from veteran status [22]. The findings of this study provide further supporting evidence of the significance or importance of place in accounting for health, healthcare, and associated disparities.

That younger veterans had greater odds of having at least one HSD indicates that these are most likely veterans who have served in the Gulf-war era and the more recent Middle Eastern conflicts. All of the HSDs may be an issue for these veterans. For instance, there may be a common misperception that veterans are entitled to receive lifetime medical insurance and care. However, coverage for medical services is not guaranteed for all military veterans regardless of combat status [23]. While it is often cited that accessing services and availability of services may be a difficult issue for rural veterans, the reality may be more complicated than simple access. To receive veteran-related medical insurance and coverage, there is a prioritization system based on medical conditions related to military service [24]. Furthermore, there is an income-based adjustment for priority level for eligibility for services [23]. For veterans returning from a theater of combat, one must apply for healthcare coverage within five years after honorable or general discharge from active duty or risk losing eligible services [23,24].

Smoking and binge drinking are health-related risk behaviors. Their strong association with HSDs and rural veterans is worth noting and addressing in any interventions focused on reducing HSDs for this population. It may be the case that binge drinking is indicative of some measure of self-medication. Furthermore, engaging in these risky health behaviors may indicate that other similarly risky behaviors not measured in this study are also practiced.

Lower income and less educated rural veterans are a more vulnerable group of veterans. That these characteristics are also strongly associated with HSDs should be taken into consideration when developing any outreach or interventions aimed at reducing their HSDs.

It is also interesting and notable that African American race was protective both generally and in the instance of rural residency for HSDs. It may very well be the case that, in contrast to their other race and ethnicity counterparts, African American veterans have applied for, received, and used the healthcare benefits they are eligible for. These findings bear further examination.

Several potential limitations to this study should be noted. First, the survey is based on telephone-derived data and may lack representation because those who could not be reached by phone could not participate in the survey. For instance, persons of lower socioeconomic status may have been excluded because of poorer phone access. Widespread use of answering machines and caller identification now allow people to filter their phone calls, potentially leading to a passive refusal to participate in surveys such as the BRFSS. Nevertheless, call filtering is beyond the control of survey administrators and the vast majority of US residents live in households with telephones, which minimizes the bias of lack of phone access. Additionally, US cell phone numbers are now included in the pool of phones contacted for the survey ensuring the widest possible net being cast. A second limitation is that the survey used close-ended questions, which limit participants’ options to fully explain response choices. Nonetheless, the survey questions were worded such that the answer choices covered a wide range of response possibilities. A third, and related, limitation is that the answers are self-reported, which introduces the possibility of recall bias on the part of the survey participants. In addition to recall bias with self-reported data on health issues, there is the possibility of either under-reporting or over-reporting health concerns. Fourth, geographic locale is not provided for US veterans residing in Guam, Puerto Rico, or the US Virgin Islands. This may result in an under-reporting or under-identification of rural veterans. Finally, we were unable to identify a number of potentially important characteristics of the military veterans including combat status, location of services, deployment status, and length of active military service. Despite these limitations, there are a number of strengths worth noting. This is a population-based study analyzing data representative of the US population of veterans—rural and urban alike. Moreover, the data are surveillance data collected separately from any medical records or VA collected data.

5. Conclusions

The study described here fills identified epidemiological gaps in our knowledge regarding rural US military veterans and HSDs. Rural veterans have greater odds of having an HSD when compared to their urban counterparts. A major strength of the study is that non-medical and non-VA data were analyzed. The findings are not only interesting but important and should be used to inform interventions to reduce HSDs for rural veterans.
