Abstract
Rural residents experience higher disability, mortality, and poverty rates than their urban counterparts; they also have more barriers to accessing care, including nursing home care. Meanwhile, the proportion of nonelderly adult nursing home residents (<65 years old) is growing, yet little is known about this population and barriers they face trying to access care, especially in rural areas. This qualitative study uses data from 23 semistructured interviews with rural hospital discharge planners in five states to identify specific barriers to finding nursing home care for nonelderly rural residents. We grouped those barriers into three primary themes—payment status, fit, and medical complexity—as well as two minor themes—caregivers and bureaucratic processes—and discuss each in the article, along with potential policy and programmatic interventions to improve access to nursing home care for nonelderly rural residents.
Introduction
At any given time, more than 15% of the nearly 1.5 million nursing home residents in the United States are under the age of 65 years (Centers for Medicare & Medicaid Services, 2015). In recent years, the number of nonelderly nursing home residents has steadily grown (Miller, 2011), from 9% in 1996 (Agency for Healthcare Research and Quality, 2001) to 15% in 2012 (Harris-Kojetin, Sengupta, Park-Lee, & Valverde, 2013). Nonelderly (<65 years of age) residents differ from residents above age 65 in their health and demographic profiles, insurance status, and health care utilization. For example, nursing home residents ages 22 to 64 years are more likely than their counterparts above 65 years to be long-stay residents and to need help with activities of daily living (ADLs; Irvin, Denny-Brown, Morris, & Postman, 2016), are less likely to use mobility devices, or have sensory impairments (Agency for Healthcare Research and Quality, 2001). However, they tend to have more mental health concerns and are more likely to be below the poverty level, to be non-White, and to have never married (Agency for Healthcare Research and Quality, 2001; Grabowski, Aschbrenner, Feng, & Mor, 2009; Simon, Lipson, & Stone, 2010). As a result, younger nursing home residents tend to have different needs and preferences than their older counterparts and require different approaches to providing for a good quality of life in long-term care (Hay & Chaudhury, 2015). Still, the vast majority of research and policy attention on nursing home residents has been focused on adults above the age of 65 years, leaving a gap in knowledge about nursing home care for nonelderly adults, especially those in rural areas, where research and data are particularly sparse (Wodchis, Fries, & Pollack, 2004). This study addresses that gap by investigating barriers to nursing home access for rural residents below the age of 65 years.
Across the United States, the overall number of people requiring long-term services and supports, including nursing home care, is growing (The SCAN Foundation, 2012), as the population is aging and the number of people living with disabilities is rising (U.S. Census Bureau Public Information, 2012). People are living longer than ever before with disabilities and complex medical conditions (Avendano, Glymour, Banks, & Mackenbach, 2009; Vos et al., 2012). In addition, the prevalence of complex conditions and comorbidities like obesity and dementia is higher than ever before (Vos et al., 2015). These issues are felt most acutely in rural areas, which experience higher disability and mortality rates and poorer health behaviors than the rest of the country (Garcia, 2017; Matthews et al., 2017; Rural Health Information Hub, 2017a), and have particularly affected nonelderly rural residents (Matthews et al., 2017). Meanwhile, rural areas have unique barriers to accessing health care in general, and long-term care, including nursing home care, in particular (Coburn & Bolda, 2001; Douthit, Kiv, Dwolatzky, & Biswas, 2015; Hutchison, Hawes, & Williams, 2005; McAuley, Pecchioni, & Grant, 2002). Rural areas have fewer nursing homes and home health agencies and also face historic shortages in the long-term care workforce at all levels, from certified nursing assistants to specialty care like psychiatry (Lee, Dooley, Ory, & Sumaya, 2013; D. Meyer, Raffle, & Ware, 2014). While some programs like the National Health Service Corps (Rural Health Information Hub, 2017b) have helped in addressing access to health care in rural areas, few efforts have focused specifically on access to long-term care in rural areas. This study will help to identify some specific barriers that could be addressed to improve access to such care.
Rural areas also have higher poverty rates and lower median incomes than urban areas (U.S. Department of Agriculture, 2017). Long-term care is expensive, and nursing home care is the most expensive form: The median cost for 1 year of nursing home care is more than US$90,000 (Reaves & Musumeci, 2015). The majority of nonelderly adults have unrealistic expectations about their risk of needing long-term care (Henning-Smith & Shippee, 2015), and most have made no plans for it, financial or otherwise (Thompson et al., 2013). Few people can afford to pay for long-term care privately, and most private insurance plans offer little or no coverage for long-term care. As a result, state Medicaid programs are responsible for a substantial portion of costs, funding more than half of all long-term care (Reaves & Musumeci, 2015) and nearly two thirds of nursing home care (Harrington, Carrillo, & Garfield, 2015), amounting to more than US$150 billion in annual Medicaid spending on long-term care (Eiken, Sredl, Burwell, & Saucier, 2016). This has important implications not only for federal and state budgets but also for individuals’ access to care. For example, in instances when Medicaid reimbursement rates for nursing home care are lower than reimbursements for Medicare or private pay, nursing homes may have a disincentive to accept patients on Medicaid. These issues are particularly salient for nonelderly adults needing nursing home care, as they are more likely than nursing home residents above 65 years to be in poverty and rely on Medicaid for assistance (Agency for Healthcare Research and Quality, 2001).
Patient preference and public education about long-term care generally, and nursing home care specifically, are also important. In general, individuals prefer to remain in their homes, rather than go to nursing homes (Keenan, 2010). Indeed, the majority of people needing long-term care, including individuals below 65 years, reside in the community and receive unpaid caregiving assistance from family and friends (Kaye, Harrington, & LaPlante, 2010). However, nursing home care is sometimes necessary for more serious care needs or when the home setting is unsafe or home health care or family caregiving is unavailable. Still, younger residents have voiced concerns about living in a nursing home group setting and losing privacy and autonomy (Ho, Kroll, Kehn, Anderson, & Pearson, 2007). Furthermore, although federal policy mandates that state Medicaid programs provide coverage for nursing home care, many home and community-based services and programs are left to the discretion of states, which can choose to fund them through Medicaid waiver programs (Center on Budget and Policy Priorities, 2016; Shapiro, 2010).
Meanwhile, federal policy prohibits federal Medicaid funding for any care for adults ages 21 to 64 years in “institutions for mental diseases” (IMDs), which are defined as institutional settings with more than 16 beds whose primary function is to diagnose, treat, and care for individuals with mental illness. This policy known as the “IMD exclusion” has existed since Medicaid was enacted in 1965 and was designed to aid in deinstitutionalization, or moving treatment of mental illness from institutions to the community (Blyler et al., 2016). In doing so, however, it has created additional barriers to care for many low-income nonelderly adults with chronic and persistent mental illness, and it has had the unintended consequence of that population relying more on nursing homes for long-term care than on psychiatric institutions or community-based care (Legal Action Center, n.d.; Simon et al., 2010; Torrey, 2013). Although increasing attention is being paid to such policies in the context of larger debates about the future of Medicaid and health care financing, little is known about whether, or how, these issues transpire in rural areas.
The goal of this analysis is to examine barriers to nursing home placement for nonelderly rural residents to inform ongoing clinical and policy efforts to ensure appropriate long-term care access and use in rural communities.
Method
Data and Sample
Data for this study came from semistructured interviews with 23 discharge planners, all of whom work in rural U.S. hospitals and self-identified as the hospital’s primary discharge planner. The discharge planners’ professional backgrounds included both nursing and social work. All but one of the discharge planners worked in a Critical Access Hospital (CAH); the remaining hospital was a rural Prospective Payment System (PPS) hospital. The sample was drawn from five states: Georgia, Idaho, Minnesota, Pennsylvania, and Wisconsin. These states were chosen to represent the four census region (with two in the Midwest) because they each have sizable rural populations (>20% of each included state’s population are rural). Discharge planners were contacted about the study in multiple ways: (a) by the state Flex program coordinator or state office of rural health who knew the participants’ roles in their hospital workplaces, (b) referred by other subjects in the sample, and (c) in the case of Wisconsin, by the Rural Wisconsin Health Cooperative, which works close with rural hospitals across the state. Discharge planners volunteered to participate and were not provided any compensation. This study was approved by the University of Minnesota Institutional Review Board.
Data Collection
Interviews were conducted between November, 2016, and February, 2017. Twenty-one of the 23 interviews were conducted by phone by one of the study authors. The interviewer on each call took notes during the interview and also audio-recorded each interview. Two discharge planners requested to complete the interview by email instead of by phone and provided responses in this manner. The phone interviews lasted 20 to 30 min each and consisted of 11 questions. The primary purpose of the interview was to understand medical and nonmedical barriers to nursing home care for rural residents. However, the interview included two questions about nonelderly rural residents specifically: (a) “Do you ever find nursing home care for patients younger than 65?” (b) If yes, “What unique barrier(s), if any, does finding them [rural residents under 65] nursing home care present?” Answers to the latter question represent the most challenging issues faced by rural discharge planners in finding nursing home care for patients younger than 65 years; however, some of those challenges are also relevant for patients older than 65 years as well. The current study is part of a broader project looking at barriers to nursing home care for rural residents generally. We also asked the discharge planners to recommend any specific policy and programmatic interventions that could help alleviate barriers, and some of those were specifically related to serving adult residents younger than age 65.
Analysis
Following each interview, one of the researchers typed up interview summary notes, which were checked by a second researcher for completeness and for accuracy against the audio recordings. After all 23 interviews were completed, the researchers reviewed the responses to the questions about serving adult rural residents younger than 65 years, using conventional content analysis to code them for themes, in which codes and subsequent themes emerged from the data analysis (Hsieh & Shannon, 2005). The qualitative analysis was done using a grounded theory approach. The lead researcher on the project conducted the initial coding and categorized responses into themes and then checked for consistency and agreement with the other three researchers on the study team. During this process, the research team worked toward consensus to ensure intercoder reliability; the initial coder also checked those codes against the original coding to ensure intracoder reliability, revising as necessary to achieve group consensus (van den Hoonaard, 2008). We identified themes if several of the discharge planners raised the same issue. However, given the relatively small sample size, we also identified two minor themes if more than one discharge planner raised the same issue.
Results
All but two discharge planners in our study stated that they have placed adult patients younger than 65 years in nursing home care. Of those, five discharge planners stated that the process of finding nursing home care for nonelderly patients is no different than finding it for patients older than 65 years; the remaining 16 discharge planners stated that placing adult patients younger than 65 years in nursing home care was often more difficult than placing elderly patients, and posed unique challenges, which present a sufficient sample size to identify themes (Hagaman & Wutich, 2017). Specific challenges highlighted by the respondents can be grouped into three themes (ordered by frequency of mentions)—payment status, fit, and medical complexity—as well as two minor themes—caregivers and bureaucratic processes. Notably, some of these are not unique to patients younger than 65 years, although access issues may be heightened in that demographic. Details for each of those themes are included below, and illustrative quotes for each theme are shown in Table 1.

Payment Status
The most common issue raised by the discharge planners was payment status for nonelderly patients (raised by seven of the interviewees). In some cases, respondents stated that they work with adult patients younger than 65 years who need nursing home care but who cannot afford to pay for it up front. In other cases, they stated that the patient has insurance but that it does not cover nursing home care. Multiple discharge planners also mentioned nursing homes’ reluctance to accept referrals from patients with Medicaid coverage because they get a lower reimbursement rate for it and because nursing homes expect that younger residents will be in the nursing home longer term, so lower reimbursements add up. Another discharge planner discussed the challenge of patients getting stuck with large bills that they cannot always afford to pay. She went on to describe situations in which nursing homes refuse to take patients who have outstanding bills for previous nursing home stays, compounding access issues, especially for low-income individuals.
Fit
Six of the discharge planners stated that one of the main barriers to placing nonelderly rural residents in nursing home care is related to poor fit between the patient and the potential nursing homes, either from the perspective of the receiving nursing home or from the perspective of the patient, their family, and/or that of their case management team. Discharge planners stated that it is often not a good fit for the patient’s psychosocial needs to live in a nursing home that has a majority of residents who are older and that nursing homes sometimes refuse patients younger than 65 years because they are concerned about older residents getting along well with younger residents. In particular, they discussed concerns that patients younger than 65 years may have different preferences, tastes, and lifestyle habits than nursing home residents older than 65 years and that these may lead to conflict, especially in shared rooms. The discharge planners also stated that patients who need nursing home care sometimes refuse it because they do not perceive it to be a good living environment for their social and emotional needs.
Medical Complexity
Five of the discharge planners stated that the nonelderly patients they work with who need nursing home care are often more medically complex, with conditions like multiple sclerosis, cerebral palsy, amyotrophic lateral sclerosis (ALS), chronic obstructive pulmonary disease (COPD), developmental disabilities, or severe obesity. Several respondents also mentioned that they deal more commonly with mental illness, substance abuse and dependence, and end-stage alcoholism in this population and that those are difficult conditions for which to find nursing home placement. The discharge planners discussed situations in which these were the primary conditions requiring care, as well as situations in which these were co-occurring with other chronic conditions. In each of those cases, the discharge planners mentioned that nursing homes are ill-staffed and equipped to handle such complex cases on top of their current caseloads.
Caregivers (Minor Theme)
Two of the discharge planners we interviewed stated that a particular issue with the nonelderly patient population is a lack of family caregivers. One of those discharge planners explained that even in cases when younger patients have family nearby, those family members are also younger and may be in a life stage where they are taking care of young children of their own, making it more difficult to be available for the patient. Another discharge planner described situations in which individuals have lifelong disabilities and have been taken care of by their parents, but then need nursing home care when their parents are no longer able to care for them. This makes it more difficult for them to safely discharge the patient home and also leaves the patient with fewer advocates to navigate the process of finding and sustaining appropriate long-term care.
Bureaucratic Processes (Minor Theme)
Finally, two discharge planners in this study mentioned that one of the unique challenges to working with nonelderly adults who need nursing home care is working with the state or county to establish vulnerable adult status, to help them make decisions about nursing home care in the event that the patient’s decision-making capacity was compromised. While exact definitions and processes vary by state, vulnerable adult status generally refers to situations in which adults are unable to safely care for themselves and autonomously make decisions about their own treatment, finances, and legal matters. In such cases, these adults require another adult to act as a guardian and to make decisions on their behalf. In some cases, patients have put those provisions in place ahead of time; but more often, it is necessary to go through the court system to obtain vulnerable adult status and to assign a legal guardian. Certainly, not all patients would require this level of protection, but for those who do and who otherwise would be unsafe if discharged to home, it can add time and effort to discharge planning, especially in the absence of a family caregiver. Furthermore, multiple discharge planners mentioned that group homes or community-based residential facilities might be more appropriate for younger patients but that these sometimes require additional waivers from the state, which can delay the process of finding care and may require using nursing home care in the interim.
Discussion
The majority of the rural hospital discharge planners interviewed for this study indicated that they seek nursing home placement for adult patients younger than 65 years, either occasionally or regularly. Of those who find these types of placements, all but two discharge planners indicated that doing so presents particular challenges. We characterized these challenges into three themes—payment status, fit, and medical complexity—as well as two minor, or emerging, themes—caregivers and bureaucratic processes. Although not all of these themes are unique to patients below 65 years or to rural residents, their implications should be considered in light of the unique needs of working-age rural residents, a group that experiences increased risk of mortality and morbidity, compared with the older and urban adults (Case & Deaton, 2015; Garcia, 2017; Moy et al., 2017).
For payment status, the most common barrier mentioned, we heard multiple issues with individuals not having enough money to pay privately, their insurance not covering long-term care, or reluctance on the part of nursing homes to accept Medicaid for long-term stays. Three of the five states in our sample (Georgia, Idaho, and Wisconsin) did not expand Medicaid under the Affordable Care Act, which was associated with higher rates of uninsurance for working-aged adults (Garfield, Damico, Stephens, & Rouhani, 2014), making it more difficult for low-income working-aged adults to afford and access health care, as well as to put any money aside for long-term care insurance or savings. This is especially true in rural areas, where private insurance coverage among working-aged adults is less common (Foutz, Artiga, & Garfield, 2017).
For those adults who do qualify for Medicaid, our findings are consistent with prior research showing that nursing homes demonstrate the potential for preferential treatment toward individuals who can pay privately over residents on Medicaid (Ettner, 1993), especially in states with lower Medicaid reimbursement rates (M. H. Meyer, 2001), despite laws designed to restrict such practices. Similar insurance-based discrimination has been found in other sectors of health care, as well (Han, Call, Pintor, Alarcon-Espinoza, & Simon, 2015), demonstrating that this is a widespread issue, which may lead to patients relying on Medicaid being sent to lower quality facilities (Mor, Zinn, Angelelli, Teno, & Miller, 2004). Two states with substantial rural populations, Minnesota and North Dakota, address this using a system called “rate equalization,” in which nursing homes cannot charge private pay residents more than what Medicaid reimburses (North Dakota Office of Human Services, 2016; Punelli & Williams, 2016). Medicaid rate equalization may help to reduce discrimination on the basis of payment status, but only these two states currently require this (North Dakota Office of Human Services, 2016; Punelli & Williams, 2016). Raising nursing home reimbursement rates generally may also make it easier for facilities to accept patients and provide high-quality care. Indeed, there is evidence that even small changes within nursing home funding and reimbursement have the potential to improve the care that nonelderly residents receive (Wodchis et al., 2004).
For fit, discharge planners shared issues related to patients not feeling as though a nursing home setting or population is a good fit for them; likewise, we heard about nursing homes not wanting to accept younger patients for fear that they would not fit socially within their current resident population. For medical complexity, we heard about placement challenges faced by younger and middle-aged adults with disabilities, co-occurring substance use behaviors and disorders, and conditions that require complex care. This is especially relevant for nonelderly adults, as newly admitted nursing home patients with mental illness or behavioral health problems are more likely to be younger than the general nursing home population (Aschbrenner, Grabowski, Cai, Bartels, & Mor, 2011), even though nursing homes may not provide the most appropriate care setting for younger adults with mental illness (Simon et al., 2010).
Two minor themes emerged in this analysis, both mentioned by two discharge planners each. For caregivers, we heard problems with lack of family caregivers for rural residents below 65 years with disabilities; in some cases, this was because those individuals’ primary caregivers had been their parents who were now aging and/or dealing with health problems of their own. In other cases, the individuals had adult children who were unable to provide full-time caregiving, as they were caring for their own families. Still others had no family caregivers at all, short of hiring one, which they could not always afford to do. Previous research has highlighted issues faced by caregivers of nonelderly individuals with mental illness, including lack of social support and financial strain (Corsentino, Molinari, Gum, Roscoe, & Mills, 2008); our findings add to this evidence and provide an urgent call for more attention to this often overlooked group. For bureaucratic processes, discharge planners shared stories about the time-consuming and arduous process of applying for waivers to get the patient into appropriate care and about the process of applying for vulnerable adult status with the state or county. Although both of these themes were mentioned by only two discharge planners, we suspect that they may emerge as more common issues in larger sample sizes and we believe that they are deserving of additional research to better understand their true scope and impact.
The issues we heard about from discharge planners are happening within the broader context of other compounding issues in rural America. Rural areas have higher poverty rates, higher disability rates, more pronounced issues with the opioid epidemic, poorer health behaviors, and greater health care workforce shortages, especially for specialty care, than urban areas do (Dart et al., 2015; Garcia et al., 2017; MacDowell, Glasser, Fitts, Nielsen, & Hunsaker, 2010; Matthews et al., 2017; Rural Health Information Hub, 2017b; “USDA ERS–Poverty Demographics,” n.d.). In particular, research has recently highlighted the diminishing health and well-being of middle-aged Americans, especially in rural areas (Garcia et al., 2017; Matthews et al., 2017). The stories that discharge planners shared about highly complex younger and middle-aged patients struggling to access and afford appropriate long-term care, often while battling complex health conditions, illustrate how these problems in rural areas can manifest to the detriment of those already most vulnerable.
The discharge planners we talked with also had many suggestions for policy and programmatic interventions, some of which were directly related to serving rural residents younger than 65 years. One suggestion focused on the need for more group homes, community-based residential facilities, and other “age-appropriate” options for nonelderly adults with long-term care needs. For example, one discharge planner discussed a local county nursing home that used to have a separate wing designated for adult residents below age 65 as one potential solution; however, that same discharge planner also believed that that particular solution had not been financially viable. Many of the discharge planners we talked with lamented the fact that this population does not always fit well within general nursing home populations; increasing residential service and funding options particularly through Medicaid waiver programs to help pay for them would help to address this issue. For residents with chronic and persistent mental illness, it may be helpful to allow exemptions to the IMD exclusion, allowing nonelderly adults to receive federally funded care in psychiatric institutions rather than nursing homes. This idea is currently being tested in 11 states and D.C. by the Centers for Medicare & Medicaid Services under the Medicaid Emergency Psychiatric Demonstration (Blyler et al., 2016; Centers for Medicare & Medicaid Services, 2012); however, more research is needed on how such treatment options would work in rural areas.
Similarly, multiple discharge planners stated that they would ideally like to help people remain at home, as is often their preference. Policy has shifted to support those preferences, with programs like Money Follows the Person and other efforts to rebalance long-term care toward home and community-based services (Nishita, Browne, Hawk, Whitfield, & Rosen, 2013). However, respondents noted that a lack of willing and able caregivers (formal and informal) makes this difficult. Increasing the number of and funding for home health care services, particularly services that can offer 24-hr care, would help to keep people home, when appropriate. Some of the discharge planners we talked with had specific ideas to facilitate this. Two of them suggested that community paramedic programs can be useful in helping to keep people safe at home. Evidence suggests this strategy may be helpful in rural communities (Flex Monitoring Team, 2014); however, it should be used to complement, rather than as a substitute for other forms of long-term care. Another described a volunteer program with local caregivers who are able to act as a bridge between discharge from the hospital and more formal care systems. Yet another discharge planner stressed the important role that transition nurses can play in helping to facilitate a safe discharge to home. In the absence of such long-term services and supports, especially around caregiving, it becomes much more difficult to help this population avoid nursing home care even if they would like to.
Finally, one of the discharge planners we talked with stressed the importance of developing and maintaining good relationships with area nursing homes to facilitate honest and efficient conversations between the hospital and nursing homes about whether or not someone would be a good fit. This speaks to the broader issue of the importance of facilitating difficult conversations between facilities, providers, families, and patients. Discharge planners, nurses, and social workers play pivotal roles in this process (Henning-Smith, 2017); rural hospitals may benefit from finding ways to invest in time and effort to engage in such conversations, education, and relationship building. Indeed, research indicates that hospital discharge planners often provide limited guidance to patients and caregivers on how to select appropriate and high-quality nursing homes, which can lead to ill-informed choices based largely off of proximity to the nearest facility rather than appropriateness, fit, or quality (Tyler et al., 2017). Putting greater emphasis on the importance of discharge planners providing guidance and education during the process of selecting a long-term care facility, combined with more communication and transparency with the receiving facilities, may facilitate patients going to the most appropriate setting.
This study should be considered in light of its limitations. As with any qualitative study, caution should be exercised to generalize the results beyond our respondents and the five states that they represent. However, the issues that they raised are consistent with research on current population health and health care access issues in rural America (Coburn, 2002; Coburn & Bolda, 2001; Hutchison et al., 2005; Matthews et al., 2017; Rural Health Information Hub, 2017b). Future research should investigate to what extent the barriers they face are universal and how they should most effectively be addressed. In addition, because barriers to nursing home care for nonelderly adults were not the sole focus of this study, there are likely other issues related to this phenomenon that discharge planners would have raised if they had been asked more detailed follow-up questions. More research is needed on this understudied and growing population. Furthermore, many of the issues raised (e.g., accessing long-term care for medically complex patients) pose challenges to finding nursing home care for patients of all ages. Our findings represent those challenges most commonly cited in finding care for nonelderly adults but are not necessarily unique to that population.
Conclusion
Rural America faces myriad challenging health care issues: aging populations, higher disability and poverty rates, poorer health behavior, and more difficulty accessing care. Perhaps in no issue are these problems illustrated so well as in the barriers that rural hospital discharge planners face in finding long-term care for younger and middle-aged rural residents with disabilities and complex health problems. The discharge planners we talked with in this study described problems with fit, in which residents younger than 65 years may not be a good match for older nursing home populations; problems with medical complexity, including chronic conditions, substance abuse, and disability; lack of willing and able caregivers (formal and informal); problems affording care or finding facilities willing to accept Medicaid; and bureaucratic processes, that can slow transitions into appropriate long-term care settings. The issues—and interventions—raised in this study may be broadly applicable to rural America as it grapples with how best to respond to changing population dynamics and health needs.
