Understanding domains of health-related quality of life concerns of Singapore Chinese patients with advanced cancer: a qualitative analysis

Natural Language Processing for Automated Classification of Qualitative Data From Interviews of Patients With Cancer

OBJECTIVES

This study sought to explore the use of novel natural language processing (NLP) methods for classifying unstructured, qualitative textual data from interviews of patients with cancer to identify patient-reported symptoms and impacts on quality of life.

METHODS

We tested the ability of 4 NLP models to accurately classify text from interview transcripts as "symptom," "quality of life impact," and "other." Interview data sets from patients with hepatocellular carcinoma (HCC) (n = 25), biliary tract cancer (BTC) (n = 23), and gastric cancer (n = 24) were used. Models were cross-validated with transcript subsets designated for training, validation, and testing. Multiclass classification performance of the 4 models was evaluated at paragraph and sentence level using the HCC testing data set and analyzed by the one-versus-rest technique quantified by the receiver operating characteristic area under the curve (ROC AUC) score.

RESULTS

NLP models accurately classified multiclass text from patient interviews. The Bidirectional Encoder Representations from Transformers model generally outperformed all other models at paragraph and sentence level. The highest predictive performance of the Bidirectional Encoder Representations from Transformers model was observed using the HCC data set to train and BTC data set to test (mean ROC AUC, 0.940 [SD 0.028]), with similarly high predictive performance using balanced and imbalanced training data sets from BTC and gastric cancer populations.

CONCLUSIONS

NLP models were accurate in predicting multiclass classification of text from interviews of patients with cancer, with most surpassing 0.9 ROC AUC at paragraph level. NLP may be a useful tool for scaling up processing of patient interviews in clinical studies and, thus, could serve to facilitate patient input into drug development and improving patient care.

Employing cognitive interviewing to evaluate, improve and validate items for measuring the health-related quality of life of women diagnosed with ovarian cancer

Background

Use of patient-reported outcome measures in clinical settings facilitate the delivery of better health care to improve patient health outcomes. Previously collected qualitative data indicated themes that could inform items for a health-related quality of life measure. This study investigated the content validity of items for inclusion in a new health-related quality of life measure suitable for patients with ovarian cancer.

Methods

Cognitive interviewing techniques were used with fourteen women diagnosed with ovarian cancer and at different times since diagnosis, to evaluate items derived from the previously collected qualitative dataset. A set of draft items was administered via telephone, Zoom and WhatsApp app together with questions on item meaning and wording. Interviews were transcribed and thematically analysed.

Results

Four broad themes emerged in relation to the questionnaire construction and comprehension of items: intent and clarity, wording, relevance and context, and overall questionnaire construct. All draft items were adjusted based on the interview findings. A final set of 38 health-related quality of life items comprised 7 items describing physical health and functioning, 21 describing emotional wellbeing and 10 items describing social wellbeing; each rated on a five-point frequency response scale.

Conclusion

The items reflected a range of personal experiences associated with the patient clinical journey, creating a health-related quality of life tool specific to women diagnosed with ovarian cancer. The cognitive interviewing process established content validity for the tool, thereby, preparing it for field testing and evaluation of its psychometric properties. This study highlighted the fundamental role of cognitive interviewing during health-related quality of life questionnaire development to ensure that item content is grounded in patient feelings, functioning and meaning.

Searching for a harmonious survival: the experience of quality of life of urological cancer survivors

PURPOSE

This study aimed to analyze the experience of quality of life for urological cancer survivors.

METHODS

This is a qualitative narrative research based on the experience-centered approach. Twenty-one semi-structured face-to-face interviews were conducted with 12 survivors of urological cancer at different survival seasons. Participants were recruited from the convenience sampling. The thematic analysis approach was used to analyze the data. The findings are presented as narrative syntheses. The standards for reporting qualitative research (SPQR) were used in this study.

RESULTS

Two narrative syntheses were constructed: (1) Rupture in the different dimensions of QoL; and (2) QoL: Searching for a harmonious survival, each presenting their respective sub-themes. After the rupture in the different dimensions of QoL, the survivors resigned themselves and searched for a harmonious survival despite the physical, social, and psychological changes imposed by cancer treatments. Survivors achieved a new meaning of QoL with the support of family, hope, and spirituality.

CONCLUSIONS

The results highlight the changes experienced by survivors in different dimensions of QoL and the search for harmonious survival. Based on QoL experience reported in this study, health professionals can plan survival care and interventions that mitigate the consequences of treatment on QoL.

Experiences and perspectives of suffering in cancer: A qualitative systematic review

PURPOSE

Suffering refers to a situation in which a person's illness and condition threaten their integrity. The aim of this systematic review was to synthesize qualitative studies that explored suffering of persons with cancer.

METHOD

A qualitative systematic review was conducted. Psych Info, PubMed, and CINAHL were searched for relevant studies. Methodological quality was independently assessed using the Critical Appraisal Checklist from Joanna Briggs Institute (JBI). A meta-aggregative approach was utilized to analyze and synthesize the data that focused on how persons with cancer perceive suffering across their illness trajectory.

RESULTS

Twelve articles reporting the experiences of 230 participants were synthesized. Three synthesized findings were generated from the articles: suffering the loss of normality, suffering in relation to others and existential suffering. Suffering affects the person's normal activities of life and cause the loss of normality. Suffering in relation to others refers patients' suffering also impacts on and is impacted by those around them. The last synthesized finding refers to impact of suffering on patients' whole sense of being. In addition, feelings of hopelessness, and other mental anguish are inevitable responses that lead the patients to think about death. The overall methodological quality resulted in a ConQual rating of moderate for the synthesized findings.

CONCLUSION

The persons' suffering not only affects themselves but also others, particularly close relatives. The suffering experienced is complex and goes well beyond the immediate impact of physical symptoms and treatment.

Culture-Related Health Disparities in Quality of Life: Assessment of Instrument Dimensions Among Chinese

Background: Health-related quality of life (HRQoL) is one of the major focuses of primary care. However, HRQoL instruments used in China are mainly developed from Western countries. Such instruments may not cover all important health concepts valued by the Chinese as health is a culture-specific concept.

Objectives: The objectives of this study are to identify culture-specific health dimensions and culture-related health disparities in primary care that are considered important by Chinese living in China.

Methods: A purposive sample of 164 adult Chinese (67 healthy persons and 97 patients) were interviewed face to face. In-depth open-ended questions were asked to elicit culture-specific dimensions of quality of life in primary care settings in China.

Results: Twelve health dimensions were identified. Five most frequently mentioned dimensions were: mood (N = 52, 31.71%), physical activities (N = 48, 29.27%), work (N = 40, 24.39%), diet (N = 32, 19.51%), and vitality (N = 28, 17.07%). Significantly more healthy persons reported mood (49.25 vs. 19.59%, P < 0.001), mindset (16.42 vs. 0.00%, P < 0.001), and self-care (11.94 vs. 2.06%, P = 0.016) characterizing good HRQoL, while more patients emphasized on work (4.48 vs. 38.14%, P < 0.001). Diet and vitality appeared to be culture-specific dimensions related to health among Chinese.

Conclusions: To better adapt or develop HRQoL instruments for Chinese, dimensions or items regarding diet might be included and disparities in the meaning of vitality between Chinese and Western cultures should be considered.

Lifestyle and Symptom Management Needs: A Network Analysis of Family Caregiver Needs of Cancer Patients

Previous research on the needs of family cancer caregivers (FCCs) have not elucidated associations between specific caregiving needs. Network analysis, a statistical approach that allows the estimation of complex relationship patterns, helps facilitate the understanding of associations between needs and provides the opportunity to identify and direct interventions at relevant and specific targets. No studies to date, have applied network analysis to FCC populations. The aim of the study is to explore the network structure of FCC needs in a cohort of caregivers in Singapore. FCCs (N = 363) were recruited and completed a self-report questionnaire on socio-demographic data, medical data on their loved ones, and the Needs Assessment of Family Caregivers-Cancer scale. The network was estimated using state-of-the-art regularized partial correlation model. The most central needs were having to deal with lifestyle changes and managing care-recipients cancer-related symptoms. The strongest associations were between (1) having enough insurance coverage and understanding/navigating insurance coverage, (2) managing cancer-related pain and managing cancer-related symptoms, (3) being satisfied with relationships and having intimate relationships, and (4) taking care of bills and paying off medical expenses. Lifestyle changes, living with cancer, and symptom management are central to FCCs in Singapore. These areas deserve special attention in the development of caregiver support systems. Our findings highlight the need to improve access to social and medical support to help FCCs in their transition into the caregiving role and handle cancer-related problems.

End-of-Life Care Provided for Cancer Patients: A Metasynthesis Study

In the health care setting, and especially in cancer patients nearing the end of life, administrators, medical staff, patients, and families face challenges of a social, legal, religious, and cultural nature in the process of care. The present study aimed to perform a metasynthesis of qualitative studies conducted on providing end-of-life care for cancer patients. The present metasynthesis was conducted using Sandelowski and Barroso's method. A literature search was performed in PubMed, Scopus, Web of Science, and Embase databases, from the inception to date, and a total of 21 articles were identified as eligible for inclusion in the study. Critical Appraisal Skills Programme (CASP) criteria were used for assessing the articles, and data were analyzed by the subject review. Six themes were extracted for end-of-life care including psychological support, palliative support, educational-counseling support, spiritual support, preferential support, and supportive interactions, each comprising a number of categories. The most frequently mentioned categories were high-value care (67%) and adaptive acceptance (57%). The findings of this metasynthesis support the view that nurses are moral agents who are deeply invested in the moral integrity of end-of-life care involving assisted death. The present study showed that providing high-value care and facilitating adaptive acceptance are important constituents of a holistic strategy for providing end-of-life care to cancer patients.

Quality of life of cancer patients at palliative care units in developing countries: systematic review of the published literature

Purpose

This systematic review aims to summarize factors that influence the quality of life (QOL) of advanced cancer patients in palliative care (PC) in developing countries. Understanding this context in developing countries milieu is necessary; however, this outcome is rarely reported.

Methods

Following the PRISMA guidelines, the electronic databases MEDLINE, Embase, CINAHL, and Web of Science were systematically searched using the search terms: QOL, cancer, PC, and names of all developing countries. Studies with less than ten subjects, qualitative or pilot studies, reviews, conference abstracts, and that reported validation of QOL questionnaires were excluded.

Results

Fifty-five studies from 15 developing countries in the African (n = 5), Latin America and the Caribbean (n = 10), and Asian (n = 40) region were included in the narrative synthesis. 65.4% were cross-sectional, 27.3% were cohort studies, 7.3% were RCTs or quasi-experimental studies. Around 30 QOL factors were studied with 20 different types of QOL instruments. Advanced cancer patients who were older, married/ever married, participated in additional care within PC, used complementary and alternative medicine (CAM), and practiced spirituality/religiosity showed higher QOL score. Low educational level and high depression were associated with a lower QOL.

Conclusion

Various factors affect QOL among cancer patients in PC. Patients valued the use of CAMs; however, the quality and safety aspects should be properly addressed. Important factors that influenced the QOL score were social and spiritual support. While there is a general need to develop PC strategies further, recognizing patients’ needs should be prioritized in national cancer programs.

Validation of the Needs Assessment of Family Caregivers-Cancer scale in an Asian population

BACKGROUND

The Needs Assessment of Family Caregivers- Cancer (NAFC-C) scale is shown to have adequate psychometric properties in assessing family caregiver needs during the cancer journey and its psychometric properties have been studied only in Western populations. This study sought to validate the NAFC-C in an Asian population for wider applicability.

METHODS

Participants (n = 363) completed questions on sociodemographics, the Depression Anxiety Stress Scale, the Zarit Burden Interview, the Caregiver Quality of Life Index-Cancer scale, and the NAFC-C.

RESULTS

Results revealed good internal consistency, test-retest reliability, and concurrent validity of the NAFC-C. Confirmatory factor analysis did not demonstrate a good fit of the NAFC-C in our sample. Exploratory factor analysis revealed a similar factor structure in this study's population. Further reliability and validity analyses with the EFA factor structure demonstrated similar reliability and validity assessments.

CONCLUSIONS

The NAFC-C is shown to be applicable in an Asian population. It would be a useful instrument for determining family caregivers' needs and to inform future interventions to address those needs and improve or maintain quality of life in both patients and their caregivers.

"What I was and what I am": A qualitative study of survivors' experience of urological cancer

PURPOSE

Most qualitative studies do not explore experience throughout the urologic cancer survival trajectory. Moreover, the evidence of the experience of cancer survivors that focuses on the contextual aspects of culture is scarce in oncology literature. This study aimed to analyze the survival experience of urological cancer from the perspective of men.

METHOD

This was a narrative research based on the concepts of culture derived from the interpretative medical anthropologic approach. Semi-structured interviews were conducted with 10 male survivors of urological cancer at different survival seasons. Seven participants agreed to a second interview, which resulted in 17 interviews. The data were analyzed using a five-phase thematic analysis approach. The findings are presented as narrative syntheses. The standards for reporting qualitative research (SPQR) was used in this study.

RESULTS

Two narrative syntheses were constructed: "The journey of urological cancer: discovering oneself as a survivor" and "What I was and what I am today": the disruption on the body and life. The narrative synthesis shows that survivors undergo transitions of identity from being healthy men to wrecked men. The survivors tried to present themselves as normal men to keep their masculinity intact. However, the experience of survival constituted a process of liminality and biographical disruption.

CONCLUSION

The experience of surviving urological cancer has highlighted the physical, emotional, and social challenges experienced by these male survivors. It is recommended to oncology nurses that nursing care should be planned along survival seasons considering the survivors' individual and subjective experiences.

More comprehensively measuring quality of life in life-threatening illness: the McGill Quality of Life Questionnaire - Expanded

BACKGROUND

Domains other than those commonly measured (physical, psychological, social, and sometimes existential/spiritual) are important to the quality of life of people with life-threatening illness. The McGill Quality of Life Questionnaire (MQOL) - Revised measures the four common domains. The aim of this study was to create a psychometrically sound instrument, MQOL - Expanded, to comprehensively measure quality of life by adding to MQOL-Revised the domains of cognition, healthcare, environment, (feeling like a) burden, and possibly, finance.

METHODS

Confirmatory factor analyses were conducted on three datasets to ascertain whether seven new items belonged with existing MQOL-Revised domains, whether good model fit was obtained with their addition as five separate domains to MQOL-Revised, and whether a second-order factor representing overall quality of life was present. People with life-threatening illnesses (mainly cancer) or aged > 80 were recruited from 15 healthcare sites in seven Canadian provinces. Settings included: palliative home care and inpatient units; acute care units; oncology outpatient clinics.

RESULTS

Good model fit was obtained when adding each of the five domains separately to MQOL-Revised and for the nine correlated domains. Fit was acceptable for a second-order factor model. The financial domain was removed because of low importance. The resulting MQOL-Expanded is a 21-item instrument with eight domains (fit of eight correlated domains: Comparative Fit Index = .96; Root Mean Square Error of Approximation = .033).

CONCLUSIONS

MQOL-Expanded builds on MQOL-Revised to more comprehensively measure the quality of life of people with life-threatening illness. Our analyses provide validity evidence for the MQOL-Expanded domain and summary scores; the need for further validation research is discussed. Use of MQOL-Expanded will enable a more holistic understanding of the quality of life of people with a life-threatening illness and the impact of treatments and interventions upon it. It will allow for a better understanding of less commonly assessed but important life domains (cognition, healthcare, environment, feeling like a burden) and their relationship to the more commonly assessed domains (physical, psychological, social, existential/spiritual).

A concept analysis of the existential experience of adults with advanced cancer

BACKGROUND

Attention to the existential dimension of an individual's experience during serious illness is important. However, existential concerns continue to be poorly defined in literature, leading to neglect in the clinical realm.

PURPOSE

This concept analysis seeks to clarify the concept of the existential experience within the context of adults with advanced cancer.

METHODS

Rodgers' evolutionary method of concept analysis was used.

DISCUSSION

Existential experience in adults with advanced cancer is a dynamic state, preceded by confronting mortality, defined by diverse reactions to shared existential challenges related to the parameters of existence (body, time, others, and death), resulting in a dialectical movement between existential suffering and existential health, with capacity for personal growth. Personal factors and the ability to cope appear to influence this experience.

CONCLUSION

These findings can drive future research and enhance clinician ability to attend to the existential domain, thereby improving patient experience at end-of-life.

Physical, psychological, social, and spiritual aspects of end-of-life trajectory among patients with advanced cancer: A phenomenological inquiry

The study examined and described the perspectives of people living with advanced cancer and the changes over time in their needs and experiences. This paper reports the accounts of 11 terminally-ill people who gave a total of 25 in-depth interviews. Participants were recruited when they began receiving home hospice care service, and they were followed up over time, as their disease progressed. Framework method was used to organize the data and identify themes. The findings highlighted that end-of-life care needs to be holistic, encompassing physical, psychological, social, and spiritual needs, as well as dynamic along the course of disease progression.

Burden of cancer pain in developing countries: a narrative literature review

Cancer pain is one of the most common, feared, debilitating, and often undertreated symptoms among cancer patients. It needs attention since it has a significant impact on the quality of life (QoL) of the patients. Also, since cancer has emerged as a major health problem in developing countries, there is a need to strengthen preventive strategies for effective cancer pain management and provide comfort to cancer patients. Nonetheless, various barriers limit developing countries toward optimal cancer pain management. To bridge the gap between adequate pain management and burden of cancer pain in developing countries, a comprehensive understanding of the limitations faced and the prevalence of cancer pain should be addressed. The aim of this literature review is to provide a deeper understanding on the factors associated with cancer pain as well as barriers toward optimal cancer pain management in developing countries. Some of the barriers addressed were administrative, judicial, economic, and professional barriers. Also, estimates on the prevalence of cancer pain and detrimental effects of pain on the QoL of cancer patients have been addressed. In summary, pain, which is one of the most debilitating symptoms of cancer, remains uncontrolled and undertreated in developing countries. It has a profound impact on the patient’s QoL and can have physical, psychological, and social consequences; therefore, it needs to be managed urgently and appropriately. Most importantly, optimal treatment of cancer pain should be highlighted as a priority in developing countries and concerted efforts should be made to eliminate different barriers discussed in this review for effective and humane care.

The Experience of Counseling Among a Singaporean Elderly Population: A Qualitative Account of What Clients Report as Beneficial

Adjustments that accompany ageing pose a challenge to the mental health of the elderly. Psychologically based counseling has been documented in Western societies as an appropriate intervention for elderly persons with depressive episodes. There is however very little research documenting how Asian elderly populations experience and benefit from counseling. This study addresses this research gap through a qualitative study based on post-counseling interviews with a sample of 41 elderly persons who received counseling at a dedicated organisation catering to the elderly in Singapore. The qualitative data revealed that clients benefitted from counseling through better emotional management - they received emotional support, found emotional healing and learnt to deal with the emotions associated with grief and loss. Clients also reported that counseling assisted them in decision making processes - older persons were able to conceive of alternatives to their predicament, obtained insights to embark on change, were enabled to take the perspective of others and found validation for their decisions. While many elderly clients greatly appreciated and benefitted from this service, citing demonstrable changes, among the very old such changes were uncommon. Cultural explanations for these differential reports and possible directions for much needed future research are provided.
