Changes in Cancer Patients' and Caregivers' Disease Perceptions While Receiving Early Palliative Care: A Qualitative and Quantitative Analysis.

BACKGROUND: Little is known about the underlying mechanisms through which early palliative care (EPC) improves multiple outcomes in patients with cancer and their caregivers. The aim of this study was to qualitatively and quantitatively analyze patients' and caregivers' thoughts and emotional and cognitive perceptions about the disease prior to and during the EPC intervention, and in the end of life, following the exposure to EPC.
MATERIALS AND METHODS: Seventy-seven patients with advanced cancer and 48 caregivers from two cancer centers participated in semistructured interviews. Their reports were qualitatively and quantitatively analyzed by the means of the grounded theory and a text-analysis program.
RESULTS: Participants reported their past as overwhelmed by unmanaged symptoms, with detrimental physical and psychosocial consequences. The EPC intervention allowed a prompt resolution of symptoms and of their consequences and empowerment, an appreciation of its multidimensional approach, its focus on the person and its environment, and the need for EPC for oncologic populations. Patients reported that conversations with the EPC team increased their acceptance of end of life and their expectation of a painless future. Quantitative analysis revealed higher use of Negative Affects (p < .001) and Biological Processes words (p < .001) when discussing the past; Agency words when discussing the present (p < .001); Positive Affects (p < .001), Optimism (p = .002), and Insight Thinking words (p < .001) when discussing the present and the future; and Anxiety (p = .002) and Sadness words (p = .003) when discussing the future.
CONCLUSION: Overall, participants perceived EPC to be beneficial. Our findings suggest that emotional and cognitive processes centered on communication underlie the benefits experienced by participants on EPC. IMPLICATIONS FOR PRACTICE: By qualitative and quantitative analyses of the emotional and cognitive perceptions of cancer patients and their caregivers about their experiences before and during EPC interventions, this study may help physicians/nurses to focus on the disease perception by patients/caregivers and the benefits of EPC, as a standard practice. The analysis of words used by patients/caregivers provides a proxy for their psychological condition and support in tailoring an EPC intervention, based on individual needs. This study highlights that the relationship of the triad EPC team/patients/caregivers may rise as a therapeutic tool, allowing increasing awareness and progressive acceptance of the idea of death.

Introduction

In the last decade, increased awareness has emerged about the benefits of integrating early palliative care (EPC) into standard care (SC) for patients with cancer and their caregivers [1, 2, 3]. Specifically, EPC has been shown to improve quality of life (QoL) [3, 4, 5, 6, 7, 8], mood [3, 4, 5, 6, 7, 8], prognostic awareness [9, 10], and symptom control [11], as well as reduce the risk of severe pain [1, 4], decrease chemotherapy use near death [3, 6, 11, 12], reduce aggressiveness of therapy [3, 6, 11, 12], increase enrollments in hospice care [3, 6, 11, 12], and improve survival [3, 13]. Benefits from EPC were also found for caregivers of patients with cancer in randomized clinical trials [14]. They reported lower depression and caregiver burden [5, 15, 16], improvements in coping strategies [5], and greater satisfaction with care [17]. Few recent reports have also indicated benefits of EPC for patients with hematologic diseases [5, 18, 19].

However, questions remain about how the EPC model achieves these valuable outcomes [20, 21, 22, 23, 24]. Previous qualitative research has addressed this issue by analyzing electronic health records [25] and interviews with oncologists and palliative care (PC) physicians [20, 26]. Other investigators have collected opinions of patients and caregivers who participated in EPC trials, identifying perceived benefits and differences compared with SC [3, 21, 27]. Specifically, patients and caregivers reported enhanced problem‐solving skills, coping strategies, and feelings of empowerment, guidance, and reassurance, through personalized symptom management and holistic support [21, 27]. The comparison between reports from participants receiving EPC and those from participants receiving oncology SC showed that EPC focuses on the person rather than the disease, and is based on a more flexible, less time‐constrained delivery model, mainly led by the patient instead of the physician [3].

In our experience of EPC [1, 4], we have observed changes in patients’ and caregivers’ language during their weekly appointments. In the current study, patients and caregivers, followed during a routine EPC practice in a real‐life, outpatient setting, were invited to participate in semistructured interviews to discuss their thoughts and feelings about the disease and treatment at different moments of their clinical course (prior to and during the EPC intervention) and to reflect on the future, including the end of life, following the exposure to EPC.

Our primary objective was to qualitatively analyze patients’ and caregivers’ reports and to describe emerging themes from a temporal perspective (past, present, and future). Our secondary objective was to apply a psycholinguistic quantitative approach to investigate how patients’ and caregivers’ cognitive and emotional processes may change along the disease trajectory, when an intervention of EPC is provided, and whether these changes mirror the main themes identified through the qualitative analysis.

Materials and Methods

Participants

This study was embedded within the outpatient Oncology and Palliative Care Unit, Civil Hospital Carpi, USL, and the outpatient Palliative Care Unit, Section of Hematology, Azienda Ospedaliera Universitaria di Modena, both located in Modena, Italy. Seventy‐seven patients with advanced cancer under EPC were consecutively enrolled between July 2020 and June 2021. Patients were asked to identify their primary caregiver/s, who was/were then also invited to participate to the study; caregiver refusal did not prevent patient participation. Forty‐eight caregivers participated in the study. Patient and caregiver eligibility required willingness to complete the interview and age ≥ 18 years. All participants provided written informed consent prior to data collection.

The study was performed in accordance with the ethical standards of the 2013 Declaration of Helsinki and was approved by the Ethics Committee of Modena (N. 0026448/20).

Organization of the EPC Units

Our outpatient PC oncology and hematology units were established in 2006 and 2012, respectively, and integrate primary oncology and hematology specialists with a palliative/supportive care team composed of one physician assistant, one fellow, and one nurse with specialized PC training and expertise, to provide comprehensive symptom management and psychosocial, spiritual, and emotional support to patients with cancer and their families, from the time of diagnosis to advanced/metastatic disease according to established guidelines [1, 4]. Patients with an advanced/metastatic cancer diagnosis (with distant metastases, in case of solid tumors, late‐stage disease, and/or a prognosis of 6–24 months) with high symptom burden are electively referred by the oncologists to receive an EPC intervention. The EPC team follows on average 20–30 patients/week and each patient on a regular basis, 1–2 times/week. Outpatients’ EPC interventions are integrated with both specialized nurse home care services and hospices [1, 4, 27].

Data Collection

Patients completed an anonymous, self‐administered pen‐and‐paper semistructured interview during their appointments at the Units. Caregivers completed the same task at home. Participants were asked to report their thoughts and feelings about their experience with the disease prior to the EPC intervention (henceforth, their past), about their experience during the EPC intervention (henceforth, their present), and about possible changes in the perception and expectations of their future, including at the end of life, following the exposure to EPC (henceforth, their future). The semistructured interview ended by a fourth, open question, allowing participants to openly express their thoughts (supplemental online Table 1). The sample characteristics were collected with the support of our database and chart reviews.

Statistical Analysis

Qualitative Analysis

Qualitative analysis was based on the grounded theory with the support of NVivo software (Burlington, MA), similar to the methodology adopted by Hannon et al. [3, 21]. Grounded theory involves the simultaneous collection and analysis of data in a systematic yet flexible way to build a theory grounded on participants’ views [28, 29]. Through a gradual, line‐by‐line coding process, we first identified elements in the reports and chose those that required closer analysis, based on their prevalence and importance; we then analyzed and discussed their relationships and produced theoretical codes to capture the process. Two PC physicians and one psycholinguist developed the coding system individually and refined it through periodic meetings and discussions.

Quantitative Analysis

Quantitative analysis was performed on the questions about the past, present, and future, by the means of the Italian version of the Linguistic Inquiry and Word Count software [30]. This is an automated, text‐analysis program that measures the percentage of use of theoretically defined categories of words in either text or speech [31]. We coded 10 categories and subcategories of interest that allowed us to investigate participants’ emotional and cognitive processes, biological processes, and agency (i.e., the perceived capacity of a subject to produce an effect [32]) (supplemental online Table 2).

Shapiro‐Wilk tests and Q‐Q plots visual inspection revealed a non‐normal distribution of the variables of interest. Therefore, nonparametric Friedman tests were performed on each one, with the factor Time (past vs. present vs. future) as an independent variable, to test differences in the use of these word categories within the two groups of participants. If any significant effect was detected, Conover's post hoc Bonferroni‐corrected pairwise comparisons were conducted to identify the specific differences. We included education level as a covariate since it provides a proxy for the width of vocabulary skills [33].

Results

One hundred thirty‐five new patients were referred to the EPC units during the recruiting process. Thirty‐five patients with 1–2 visits were considered either referred too late during the disease trajectory or undergoing interim evaluations before being referred to hospice or home care, and thus were not eligible for this study, as they were considered end‐of‐life patients. Of the remaining 100 eligible patients, 23 refused to participate because of feeling uncomfortable or not being interested, resulting in a patient response rate of 77%. Eighty caregivers were identified by patients, of whom 32 refused to participate because of feeling uncomfortable or not being interested, resulting in a caregiver response rate of 60%.

The mean age of the 77 patients enrolled was 67.4 years. Sixty‐six were diagnosed with solid cancer, whereas 11 had a hematologic malignancy. The mean time receiving EPC was 11.9 months. Thirteen patients began EPC treatment within 90 days from advanced/metastatic cancer diagnosis.

The mean age of the 48 caregivers was 55.9 years, of whom 34 cared for patients with solid cancer and 14 for patients with hematologic cancer.

I am more prone to death itself than to life: EPC allows you to understand that it doesn't matter if you live one year or two or three years. You can live with quality. And this is missing. And I would like that even those who don't understand the importance of what has been done in this ambulatory could, eventually, understand it, and they could recognize the importance it deserves, on par with or beyond oncology [spreading awareness on EPC].

Abbreviation: EPC, early palliative care.

Past

The main theme emerging from participants’ reports, when talking about their clinical experience prior to EPC, referred to physical symptoms as an unmet need, which heavily impacted on their Karnofsky Performance Status. Pain, due to either the standard therapy or the disease itself, was the most frequently reported symptom. A subtheme linked to the symptoms as unmet needs was its deleterious impact on patients’ physical functioning (including performance of daily activities), mood, and social life. The relationship between the symptoms and these three life spheres—physical functioning, mood, and social life—revealed a recurrent pattern in which physical functioning is impaired by symptoms, whereas mood and social life are impaired both by symptoms and by the inability to perform daily activities.

The most frequent reason for referral to the EPC unit was pain beyond an acceptable threshold. Some patients expressed regrets about not being informed earlier about the opportunity to control symptoms. A second reason for referral was the ineffectiveness of standard therapy.

Another element that emerged from caregivers’ reports was the deleterious psychological impact on caregivers themselves, caused by both seeing the beloved's suffering and being thrown into a difficult role that was unknown and unexpected.

See illustrative quotations in Table 2.

Present

The main emerging themes, when participants talked about their clinical experience on EPC, revolved around the perceived effects of such an intervention, its components, and the imperative need for this type of care by both patients with cancer and their caregivers.

Participants reported two distinct perceived effects. The first was related to the successful symptom management, which was appreciated and endorsed. Participants were astounded by the speed a problem that they had been suffering from, for such a long time, was solved. Symptom management restored physical functioning, mood, and social life, allowing patients to be back to their previous lives, a benefit that was often expressed metaphorically with a return from death to life. The second perceived effect, reported by participants, was empowerment. Empowerment included awareness, enhanced problem‐solving skills, and improved coping and was perceived by participants as the result of an established relationship with the palliative team, which succeeded in growing up with active and open listening, sincerity, and support. Compared with patients, caregivers were more focused on the future, even when talking about the present, and evaluated these two effects with a view to the end of life. Thus, they appreciated the effective symptom management in the perspective of a death without suffering and the empowerment in the perspective of a better, decent acceptance.

Components of the EPC that were highly appreciated by participants were the holistic approach, the focus on the person instead of the patient, and the environment. Interestingly, we also found other patients contributed to a positive and supportive environment, as highlighted by both patients and caregivers.

The theme about the need for the EPC by patients with cancer and caregivers was extremely prevalent among all participants. The importance of EPC was perceived to be discrete and complementary to the role of SC, but also as a “solo” treatment option, when SC is no longer effective.

See illustrative quotations in Table 3.

Future

The main emerging theme, when participants discussed the future, was the acceptance of the end of life. Although not all patients were comfortable with the idea of an impending and inevitable death, most of them highlighted an improved acceptance, as the result of either the awareness that death would be painless thanks to EPC or the deep relief from periodic conversations about the end of life with the palliative team. Moreover, these conversations represented the opportunity to be informed about the range of clinical options and most appropriate places for end‐of‐life care and, importantly, to be prepared for the end of life.

Caregivers’ acceptance seemed to be tied to their beloved's acceptance. Caregivers reported benefit from periodic conversations with the palliative team as well; however, the benefit seemed to be linked to the knowledge that they would not be alone, both in caring for the patient and after the patient's death.

See illustrative quotations in Table 4.

Open Question

The main emerging theme for both patients and caregivers, when responding to the open question, was gratitude. Gratitude was expressed toward the EPC model itself and, often, together with the hope that this model experience can be spread, as much as possible. Gratitude was also expressed to the palliative team and to the caregivers.

Participants also answered this question by describing positive thoughts and giving messages of hope. Interestingly, a caregiver highlighted how mere scientific knowledge is not enough to build up a satisfactory patient‐physician relationship: “Unfortunately, even scientific knowledge competence is not enough. An undisputed role in a successful relationship is played by empathy. In our past experience, we met doctors with high and excellent competences but without empathy. Palliative care provides both.” (002‐C‐001).

When talking about the past, patients used more Negative Affects (e.g., pain, loneliness, problem) and Biological Processes words (e.g., medical, treatment, to eat, to sleep) than the present and the future (Negative Affects words: p < .001 and p = .006, respectively; Biological Processes words: p < .001 and p < .001, respectively).

When talking about the present, patients used more Positive Affects (e.g., good, peaceful, reassurance) and Optimism words (e.g., improvement, hope, positive) than the past (p = .045 and p = .005, respectively). Compared with the past, there was also an increase in the use of Insight Thinking (e.g., how, thus, yet) and Agency words (e.g., I, my, me) (p = .004 and p = .009, respectively).

Caregivers used more Positive Affects words (p = .006) but also more Biological Processes words (p = .006) when talking about the present than the past.

When talking about the future, patients’ use of Positive Affects, Optimism, and Insight Thinking words remained higher than the past (p < .001, p = .008, and p = .001, respectively). Compared with the present, there was an increase in the use of Anxiety (e.g., anxiety, frightened, terrible) and Sadness words (e.g., surrender, depression, emptiness) (p = .002 and p = .003, respectively), a further decrease in the use of Biological Processes words (p = .022), and a decrease in the use of Agency words (p = .003).

Caregivers used more Insight Thinking words when talking about the future than the past (p = .002).

Overall, the beginning of EPC introduced several changes in the patients’ reports: an increase in Positive Affects and Optimism words (Fig. 1A); a decrease in Negative Affects words (Fig. 1B); an increase in Anxiety and Sadness words, but only when talking about the future (Fig. 1B); an increase in Insight Thinking words (Fig. 1C); a decrease in Biological Processes words (Fig. 1D); and, finally, a temporary increase in Agency words when talking about the present but not the future (Fig. 1E).

Discussion

In this study, patients and caregivers were asked to talk about their clinical experience prior to and during an EPC intervention and to describe possible changes in the perception and expectations of their future, including at the end of life, following the exposure to EPC.

A qualitative analysis of the most relevant and frequent emerging themes confirmed and extended the results from randomized trials by Maloney et al. [27] and Hannon et al. [3, 21]. Our study differed from these studies in that it was conducted with a wider and demographically different population, followed in the real‐life context of a standard practice of EPC. Moreover, the temporal perspective adopted in our study provides the first dynamic description of the benefits the patients can experience and the sequential changes in their thoughts and feelings, following an EPC intervention.

When referring to the clinical experience prior to EPC, patients reported being overwhelmed by unmanaged symptoms. Indeed, without a communication that enables symptom control, the benefits typical of EPC cannot be obtained [34]. The focus on the unmanaged symptoms is in keeping with study findings by Hannon et al. [3], who documented that participants reported the role of the standard oncologist as focused on the disease more than on symptom management. In our study, untreated symptoms, especially severe pain, emerged as the first and main trigger for cascading effects on physical functioning and performance of the daily routine (in the short term) and on mood and social life (later on), dragging patients in a downward spiral. Similarly to Hannon et al. [21], regrets about missed opportunities to have symptoms controlled before receiving the EPC were deep and recurrent. Consistent with this, 78.3% of our patients were referred to the EPC service later than 90 days from diagnosis. Despite calls for an integrated EPC, this still occurs late or not at all for many patients with cancer worldwide [2].

Caregivers were also impacted by these cascading effects, though with a different temporal sequence. Indeed, they experienced psychological issues in the short term and eventually an impact on physical functioning later on, mainly due to the burden of their responsibility. Thus, first‐instance interventions on caregivers should aim at decreasing the perceived burden of responsibility, by providing them practical resources and ad hoc training to face their new role, as highlighted by McDonald et al. [35] and Mohammed et al. [36].

When participants discussed the present, the most pervasive theme was related to the resolution of symptoms through the EPC. Accordingly, prompt symptom management was confirmed to be the major responsibility of PC physicians [3, 21]. This is in keeping with a previous study from our group [11], indicating an association between EPC and a significant reduction in pain severity and improvement in functional status, as early as in the first week, stressing the notion that an early integration of PC in the oncology wards may contribute to better cancer pain management. After a diagnosis of advanced cancer, the patient and caregiver face two challenges: a worsening of QoL, due to the effects of the disease and treatments, and the idea of death. Prompt symptom management limits the impact of these adverse effects, leading to a higher availability of psychological resources for coping with the new situation. By managing symptoms, the EPC improved functional status and served as a “bridge” to the discussion of psychological issues and the end of life [20].

Patients and caregivers also require empowerment to face an uncertain future. In that vein, a pervasive reported theme that emerged when discussing the present was empowerment as a consequence of EPC. A similar result was reported by the study by Maloney et al. [27], where participants perceived enhanced problem‐solving skills, better coping, feeling empowered, and feeling supported or reassured as benefits deriving from an EPC trial participation. An optimal relationship enabling the EPC team, the patient, and the caregiver to engage with one another enables empowerment and should be the ultimate goal, which may be realized only with a longstanding EPC intervention [37, 38, 39, 40]. Yoong et al. [25] found that in the EPC setting, discussion of psychosocial aspects of cancer was prominent throughout all EPC visits, compared with other physical needs that were addressed during the initial visits.

Both successful symptom management and empowerment were associated with the EPC holistic approach that emerged from participants’ reports as a plus of this intervention, together with the focus on the person and the environment. The holistic approach and the focus on the person were also identified as appreciated EPC components in the study from Hannon et al. [3, 21]. In addition, our participants reported the positive effects arising from the environment represented by the other patients and caregivers.

EPC was presented not only as a discrete and complementary intervention to SC, as in Hannon et al. [3], but also as a “solo” treatment, when SC was no longer effective, and as a care that can maximize the effects of the standard therapy. Only one patient reported to have had the initial perception of PC as a hopeless approach to the end‐of‐life comfort care, as found by Zimmermann et al. [41]. This might have been because participants were not asked specifically about their perception of the meaning of the term “palliative care” or because all were participating in the EPC service.

When asked to talk about the perception and expectations of their future, following the exposure to EPC, participants appreciated the opportunity for an increasing awareness and progressive acceptance of the idea of their end of life. This acceptance arose progressively from the perspective of a painless future and was developed further, following periodic conversations with the EPC team. None of the participants reported discomfort during conversations about their future and death. Instead, they were described as of utmost value and significance in building a deep and trusting relationship. Patients appreciated being able to discuss end‐of‐life issues openly and take the time they need to normalize a topic often described as “the elephant in the room” [42].

The quantitative analyses provided additional support to the themes revealed by the qualitative data and unveiled psychological processes that were prominent during the disease trajectory and EPC intervention. In patients’ reports on the past, there were significantly higher rates of words representing Negative Affects, which decreased and were replaced by Positive Affects and Optimism words once symptoms were controlled. The significantly higher use of words representing Biological Processes, when talking about the past, underlines how psychological resources are used and even wasted, in the attempt to overcome and survive symptoms, instead of being deployed to focus on empowerment and resilience. Several previous studies have found an association between negative affect and the ability to find benefits in negative experiences [43, 44].

When talking about their present, our participants were able to list positive aspects of their experience. Thus, being able to see things in a positive light might be a critical benefit of having a relationship with the EPC team [45]. Consistently, once symptoms were lessened, there was a significant increase in the use of Insight Thinking and Agency words. Agency words may reflect intentional causation, degree of autonomy, and manner of autonomy [46, 47]. Insight Thinking words have been associated with a drop in intrusive thinking about negative events [44] and are often observed together with Positive Affects words, representing a positive reappraisal of events that requires cognitive broadening [45].

Interestingly, when talking about the future, words associated with Agency, but not with Insight Thinking, decreased significantly. Moreover, the rate of Anxiety and Sadness words, but not Negative Affects words, increased. It is possible that the positive reappraisal of events continued, while contemplating the future, as shown by the use of the Insight Thinking words. Therefore, communication about the end of life might have led patients and caregivers to face inner, unavoidable feelings associated with the idea of death, representing a transition to acceptance.

Our study has important limitations. First, a control group of patients and caregivers who did not receive an integrated EPC intervention was absent. Second, the study generalizability is limited by the under‐representation of non‐White populations. Third, there is lack of data about personality differences among participants; however, no studies have considered the role of this variable in the context of EPC. Strengths of the study include the large number of the samples and the integrated use of qualitative and quantitative analyses of the language used by patients and caregivers on EPC, when talking about their clinical experience. The fact that this intervention represents a longstanding standard clinical practice may lend further credit to its feasibility as SC for patients with cancer.

Conclusion

Overall, our findings emphasize the benefits of a routine EPC intervention in the setting of advanced cancer. PC teams provide these benefits through a unique focus on whole‐person care, appropriate symptom management, and open communication. Audiotaping PC consultations in future studies can help to further elucidate the mechanisms by which EPC communication leads to improved coping and acceptance of the future. Importantly, to broaden the reach and impact of EPC for patients and their caregivers, we need more communication skills training for clinicians and policies focused on growing the EPC workforce [48, 49, 50].
