Reliability and validity of the Turkish version of the EORTC QLQ-C15-PAL for patients with advanced cancer

Treatment patterns and out-of-hospital healthcare resource utilisation by patients with advanced cancer living with pain: An analysis from the Stop Cancer PAIN trial

BACKGROUND

About 70% of patients with advanced cancer experience pain. Few studies have investigated the use of healthcare in this population and the relationship between pain intensity and costs.

METHODS

Adults with advanced cancer and scored worst pain ≥ 2/10 on a numeric rating scale (NRS) were recruited from 6 Australian oncology/palliative care outpatient services to the Stop Cancer PAIN trial (08/15-06/19). Out-of-hospital, publicly funded services, prescriptions and costs were estimated for the three months before pain screening. Descriptive statistics summarize the clinico-demographic variables, health services and costs, treatments and pain scores. Relationships with costs were explored using Spearman correlations, Mann-Whitney U and Kruskal-Wallis tests, and a gamma log-link generalized linear model.

RESULTS

Overall, 212 participants had median worst pain scores of five (inter-quartile range 4). The most frequently prescribed medications were opioids (60.1%) and peptic ulcer/gastro-oesophageal reflux disease (GORD) drugs (51.6%). The total average healthcare cost in the three months before the census date was A$6,742 (95% CI $5,637, $7,847), approximately $27,000 annually. Men had higher mean healthcare costs than women, adjusting for age, cancer type and pain levels (men $7,872, women $4,493, p<0.01) and higher expenditure on prescriptions (men $5,559, women $2,034, p<0.01).

CONCLUSIONS

In this population with pain and cancer, there was no clear relationship between healthcare costs and pain severity. These treatment patterns requiring further exploration including the prevalence of peptic ulcer/GORD drugs, and lipid lowering agents and the higher healthcare costs for men.

Cancer-related fatigue measures in palliative care: A psychometric systematic review

INTRODUCTION

In palliative care, the prevention and relief of fatigue are regarded as crucial goals in patients with cancer.

METHODS

A systematic review was carried out according to the COnsensus-based Standards for the selection of health status Measurement INstruments methodology. Searches were conducted in Medline (through PubMed), Web of Science, Open Gray, Scielo, Cochrane, CINAHL and EMBASE. All instruments found in each study were assessed using the COnsensus-based Standards for the selection of health status Measurement INstruments checklist and Grading of Recommendations, Assessment, Development and Evaluation approach.

RESULTS

A total of 5598 articles were identified in the different databases. In total, 57 studies describing 19 instruments were included in this study. The main properties evaluated were internal consistency, cross-cultural validity, hypotheses testing and responsiveness. All studies were evaluated with the Strobe scale with a score greater than 6 points.

CONCLUSIONS

According to the quality methodological results, Edmonton Symptom Assessment System, Problems and Needs in Palliative Care Questionnaire, European Organisation for Research and Treatment of Cancer Quality of Life 15-item Questionnaire for Palliative Care and Palliative Care Quality of Life Instrument are the recommended instruments used for assessing cancer-related fatigue in palliative care.

Can assessment of disease burden and quality of life based on mobility level in patients with end-stage cancer provide an insight into unmet needs? An exploratory cross-sectional study

PURPOSE

The purpose of this study was to: 1) investigate the differences in the needs of end-stage cancer who can move independently, using mobility aids (MA), or are bedridden; and 2) determine the effects of these different mobility levels on the patients' current quality of life (QoL), fatigue, and mental conditions.

METHODS

The study employed an exploratory prospective cross-sectional study design, which was carried out in two hospitals. The study included 99 end-stage cancer. The mobility levels of the patients were evaluated in three groups: Group 1: bedridden; Group 2: mobile with MA; and Group 3: ambulatory (under supervision or fully independent). A core cancer-specific questionnaire-integrating system for assessing health-related QOL (EORTC-QLQ-C15-PAL), the Piper Fatigue Scale (PFS), and the Hospital Anxiety-Depression scale were utilized.

The median age was 60years (31-83). Cancer types were as follows: gastrointestinal (45.5%), lung (38.4%), breast (4%), genitourinary system (4%), and others (8%). Forty-two percent of the patients were completely bedridden, 42.2% used MA, and 15.2% were independently ambulatory. The EORTC QLQ-C15-PAL physical (=.000) and emotional function values (=.029) differed among mobilization statuses. There was a significant difference among mobilization groups, in terms of behavioral values, in the PFS (=.006). The depression rate in the independent ambulatory group was lower than in the bedridden and MA groups (=0.011; =0.004).  p p p p1  p2 .

CONCLUSION

Health-related QoL, fatigue level, and emotional state vary in end-stage cancer who undergo evaluations according to their mobility levels. These patients should be assessed comprehensively, and treatment plans should be organized carefully, with a multidisciplinary approach.

Progress in palliative care for cancer in Turkey: a review of the literature

BACKGROUND

The demographic transition in Turkey is shifting the burden of diseases towards non-communicable diseases including cancer. Palliative care (PC) as a component of Universal Health Coverage assures patient and family-centred care provision throughout the spectrum of cancer.

OBJECTIVES

This study aimed to make a detailed evaluation of the progress achieved since the mid-90s and the current situation of cancer PC in Turkey.

METHODS

A literature review was conducted in PubMed, Scopus, Embase, ScienceDirect, Web of Science, Google Scholar, The Turkish Academic Network and Information Centre databases, Ministry of Health documents, Council of Higher Education's thesis 01/1995 to 07/2020. The information was categorised into the six domains: history of the cancer PC; law and regulations; education and research; opioid use; patient care and palliative centres; public awareness, psychosocial support and end of life ethics.

RESULTS

Of 27,489 studies, 331 met the inclusion criteria. The majority were published in the Turkish language and were journal articles. The findings showed that the development of PC in Turkey can be divided into three stages: early initiatives before 2000, the dissemination stage, 2000-2010 and the advanced stage after 2010. There is evidence of progress in terms of legal regulations, opioid use and number of PC services and research output. However, there is still a need for improvement in professional education, public awareness and end of life care.

CONCLUSION

There is evidence of progress, barriers and opportunities. However, bringing research into practice is needed for scale-up and integration of PC in cancer care in Turkey.

Validación de la escala QLQ-C15 PAL, para evaluar calidad de vida en pacientes en cuidados paliativos, al español colombiano

Objetivo: Validar la escala QLQ C15 PAL, para evaluar calidad de vida en pacientes en cuidados paliativos, al español colombiano, considerando un análisis psicométrico desde la teoría clásica de los test. Método: Muestra por conveniencia de 155 pacientes oncológicos atendidos por el Programa de Cuidados Paliativos de un grupo de centros hospitalarios en las ciudades de Bogotá y Cali en Colombia. Para estimar la validez de constructo, se utilizó el análisis factorial exploratorio (AFE) con rotación varimax; posteriormente, se usaron cargas factoriales para estimar el coeficiente Omega y posteriormente el análisis de Rash reconocido Análisis de la Teoría de la respuesta al ítem (TRI). El análisis fue realizado en Winsteps 2.80. Resultados: Todas las correlaciones son significativas entre los ítems de la escala Funcionamiento Global (FG) con el puntaje total obtenido en esta escala y el puntaje total del QLQ PAL-15; la misma situación ocurre con los ítems de la escala Funcionamiento Emocional (FE) que correlaciona de modo directamente proporcional y con una magnitud alta con el puntaje total del QLQ PAL-15. En cuanto al total de la escala, existe un adecuado ajuste para los ítems ya que sus valores Infit: (IMNSQ 0,99; ZSDT: -0,3) y Outfit (OMNSQ 1,02; ZSDT-0,2) se encuentran dentro de los rangos establecidos como parámetros de ajuste. Conclusiones: La validación del EORTC QLQ-C15-PAL demostró propiedades psicométricas satisfactorias al aplicarse en pacientes con enfermedad oncológica avanzada en Colombia. Se plantea para estudios posteriores realizar ajuste en la redacción de los ítems 7,11 y 13 para que estos discriminen de manera precisa el rasgo que pretenden medir.

Content validation of the EORTC QLQ-C15-PAL with advanced cancer patients and health care professionals from palliative care services in Chile

BACKGROUND

The assessment of patients' quality of life (QOL) is essential when evaluating the outcome of palliative care; however, no instruments have been validated for measuring symptoms and QOL in patients receiving palliative care in Chile. We aimed to investigate the content validity of the EORTC Quality of Life Questionnaire Core 15 Palliative Care (QLQ-C15-PAL), replicating the methods used previously to shorten the EORTC Quality of Life Questionnaire Core 30 (QLQ-C30) for use among patients in palliative care.

METHODS

This cross-sectional study was conducted from October to November 2017 in four palliative care services. Patients with advanced cancer and health care professionals (HCPs) were invited to individual interviews to determine the relevance, appropriateness and relative importance of the 30 items of the QLQ-C30 for evaluating the outcome of palliative care, and whether relevant additional issues should be included.

RESULTS

A total of 48 patients and 35 HCPs participated. The most important dimensions selected were pain, physical functioning, sleeping difficulties, emotional functioning, nausea/vomiting, fatigue, social functioning, lack of appetite, role functioning and constipation. Qualitative data identified important additional issues not covered by the questionnaire such as satisfaction with care, emotions and psychological support, as well as linguistic issues in the dyspnea and constipation items.

CONCLUSIONS

The EORTC QLQ-C15-PAL showed good content validity in the assessment of symptoms and QOL of advanced cancer patients; therefore, we recommend the use of this questionnaire in palliative care in Chile. Dyspnea and constipation items were revised by the EORTC group. More research is needed to add a social dimension for a comprehensive assessment of patients' QOL.

Quality of Life of Patients with Advanced Cancer in Palliative Therapy and in Palliative Care

Objective: To assess the quality of life of patients with advanced cancer in palliative therapy and in palliative care. Materials and Methods: Quantitative, observational, cross-sectional, and analytic study conducted in a teaching hospital in Paraná, Brazil, from January to June 2018, with 126 patients: 107 in palliative therapy; 19 in exclusive palliative care. The questionnaires for data collection were: Quality of Life Questionnaire-Core 15-Palliative, Functional Assessment of Chronic Illness Therapy-Palliative Care 14, and Edmonton Symptom Assessment System. The Spearman non-parametric coefficient test was used for the analysis. Results: The overall quality of life in palliative therapy and in palliative care was, respectively, 71.54/59.65; when correlating the total score of quality of life of the Quality of Life Questionnaire-Core 15-Palliative with the Functional Assessment of Chronic Illness Therapy-Palliative Care 14 (p = 0.001), and the Edmonton Symptom Assessment System (p = 0.001), significant difference of better quality of life was observed in the palliative therapy. Conclusion: Patients in palliative therapy have good overall quality of life, while the palliative care group reports regular quality of life. The symptoms were milder in the palliative therapy and more intense and with greater significance in palliative care; hence, knowing the compromise of quality of life will help professionals in planning interventions with transdisciplinary approach for patients and for their families.

Instruments for the functional assessment of elderly persons in palliative care: an integrative review

Abstract Objective: to identify validated instruments that can be used for the functional assessment of elderly persons in Palliative Care. Method: an integrative review focused on identifying instruments for the functional assessment of elderly persons in palliative care was carried out by searching publications in periodicals indexed in seven electronic databases. Descriptors, keywords and Boolean operators were used for a cross-database search in November 2017. A total of 357 abstracts were identified, from which 53 articles were selected for reading, of which 21 met the inclusion criteria. Results: this strategy allowed the identification of eight scales and one test for the functional assessment of elderly persons in palliative care. Conclusion: eight scales and a functional test which also provide guidelines for improving the quality of life of elderly people in palliative care were identified, demonstrating that it is practically impossible to disassociate physical functional performance from social and psychological aspects.

Quality of Life in a Hospice: A Validation of the Croatian Version of the EORTC QLQ-C15-PAL

PURPOSE

Quality of life is the cornerstone of palliative care, and assessing it requires validated and standardized questionnaires. However, the majority of questionnaires are not tested in a hospice setting. The purpose of this study is to evaluate the quality of life in a hospice using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 for Palliative Care (PAL) (EORTC QLQ-C15-PAL) questionnaire and validating it in Croatian language.

METHODS

The study was conducted prospectively on 151 consecutive patients who were evaluated at the admittance to the hospice and after 7 days. Along with the EORTC QLQ-C15-PAL, both evaluations included the Edmonton Symptom Assessment System (ESAS) and the Palliative Performance Score (PPS) version 2. Cronbach α coefficient was used to test the reliability of multi-item scales, while construct and concurrent validity was tested using the Pearson correlation coefficients. Known-group validity was evaluated using the Student t test.

RESULTS

Physical functioning, pain, and emotional functioning scales all exhibited high reliability on both assessments and met the criteria of Cronbach α ≥.70, while fatigue scale met the predetermined criteria in the follow-up assessment (α = .90). Adequate validity was also displayed, with the highest correlation coefficients between the EORTC QLQ-C15-PAL and ESAS scales recorded for the corresponding items. The EORTC QLQ-C15-PAL was also able to distinguish patients with different PPS scores, exhibiting excellent clinical validity.

CONCLUSIONS

The EORTC QLQ-C15-PAL can be used successfully in Croatian palliative care. However, inevitable issues such as low retest percentage due to short survival and low physical functioning scores need to be acknowledged in further formulations of quality of life questionnaires specific to hospice care.
