This paper provides a critical analysis of Lewis's (2014) phenomenological study investigating the experiences of informal caregivers seeking hospice and end-of-life care for loved ones with advanced dementia. The analysis examines the study's problem statement, research purpose, literature review, and theoretical framework. The paper evaluates how Lewis used Husserlian phenomenology to explore caregiver perspectives on physician-associated barriers to hospice referral—a gap in existing qualitative research that had focused primarily on quantitative survey data. Five major themes emerged from the study, revealing caregivers' experiences of loss, shifting mindsets away from curative treatment, feelings of inadequate support, delayed hospice access, and ultimate acceptance of death as relief. The analysis concludes that this qualitative approach was appropriately suited to address the research gap and provided valuable insights into informal caregiver experiences navigating end-of-life care decisions.
An estimated 5.2 million people in the United States suffer from Alzheimer's disease, with numbers expected to increase dramatically over the next 30 years. Dementia care has therefore become a significant burden on the healthcare system and will only worsen over time. While family caregivers reduce the cost of care by almost half, the psychological and physical toll on these caregivers has resulted in substantial additional medical expenses, reaching an estimated $9.1 billion for 2012. Caregiver support is therefore essential to lowering the overall cost of dementia care.
A number of barriers exist that prevent optimal health outcomes for both patients and caregivers, including those interfering with timely referrals to hospice care. Among the different barriers, those associated with physicians should be among the easiest to change. Although a significant body of research exists examining physician-associated barriers to hospice referrals and end-of-life (EOL) care in general, no qualitative studies had been performed examining these barriers from the perspective of informal caregivers. In other words, it remained unclear whether these barriers mattered to informal caregivers and dementia patients themselves.
The purpose of Lewis's (2014) study can be inferred from the opening question posed to participants: "Please describe for me your experiences seeking formal end-of-life care, and in particular hospice care, for your loved one. Please share any thoughts, feelings, and specific experiences." All other questions were designed to elaborate on this main topic. Lewis (2014) was therefore interested in understanding the experiences of informal caregivers as they cared for a loved one suffering from end-stage dementia and attempted to obtain needed services from their physicians.
Explicit research questions, other than the one stated above, were not formulated by Lewis (2014) because the study design was phenomenological. However, five main themes emerged which narrowed and defined the issues the author felt were important:
Given the main question asked of participants and the themes that emerged, Lewis (2014) was headed in the right direction if the goal was to understand the experiences of informal caregivers caring for end-stage dementia patients and seeking hospice services. Given that most research regarding this topic had been limited to survey data, it was appropriate to conduct a phenomenological study. As noted by qualitative research experts, the information gained through qualitative research is essential to helping physicians better understand the perspective of informal caregivers as they navigate EOL care options, potentially motivating improvements in timely access to hospice services.
Lewis (2014) cited both quantitative and qualitative studies addressing the topic, but the majority of findings were derived from survey data. Other literature included statistics generated by the U.S. government and the Alzheimer's Association to provide background context and justify the need for further research. The studies cited were recent, given that the manuscript was likely written in 2012 or 2013. When findings from older studies were cited, most were qualitative in nature and addressed barriers to hospice care in general, used to justify the current study.
The main critiques offered by Lewis (2014) were related to the lack of qualitative data investigating the experiences of informal caregivers of dementia patients, rather than critiques of the strengths and weaknesses of individual studies. Overall, Lewis (2014) provided a sound foundation upon which a logical argument could be built to justify further research using a qualitative study design.
Lewis (2014) chose a phenomenological study design based on the work of Edmund Husserl. The main characteristic of Husserlian phenomenology is to return to a state of knowing that existed before anything had been learned about the phenomenon of interest. Working toward this state of "pre-givenness" requires the researcher to engage in self-reflection, thereby reducing the impact of any preconceived notions or knowledge on data interpretation. Lewis (2014) described in detail the self-reflective process undertaken to achieve this methodological rigor.
Compared to grounded theory, which culls data from multiple sources, Lewis (2014) confined her data sources to informal caregivers who had experienced the loss of a loved one suffering from advanced dementia and who had tried to access hospice services. Since a grounded theory design was not utilized, a framework or diagram was not developed. Instead, Lewis (2014) identified five main themes from the data, allowing the phenomena of caregiver experience to emerge organically rather than being constrained by a pre-existing theoretical structure.
The five emergent themes reveal the lived experiences of informal caregivers navigating end-of-life care for dementia patients. These themes progress from initial loss and disappointment, through a psychological shift away from curative thinking, to feelings of isolation and delayed access to hospice, culminating in acceptance of death as relief. This thematic progression demonstrates the emotional and practical journey caregivers undertake when seeking palliative care.
