RESUMEN

Objective: Prospective cohort study to test the real-life feasibility of longitudinal patient-reported outcome measurement PROM (Integrated Palliative Outcome Scale IPOS, and NCCN Distress Thermometer DT) required for outpatients with non-curable lung or prostate cancer in comprehensive cancer centers. Methods: Assessment with paper-based IPOS and DT was observed for 15 months. We analyzed response to patients' distress (requests for supportive and palliative services) following PROM. Focus groups to comprehensively explore the user experience of patients, informal caregivers and health care professionals (HCP) supplemented the analysis. Results: Ninety-seven percent (125/129) of the patients received a questionnaire once, but quarterly assessment as recommended by certification committees was achieved only in 50% and 31% of prostate and lung cancer patients. Although both instruments were well accepted, only IPOS showed a high content validity, because some patients had difficulties in understanding the DT. Patients felt comfortable with completing the PROM, and HCP found PROM helped to structure the patient encounter. Due to organizational deficiencies in the handling of the instruments and operationalization of reactions to identified distress, the referrals to supportive and palliative services were rare. Conclusion: To facilitate consequences from PROM it should be a standardized intervention rather than assessment alone. Innovation: The patient perspective improves the implementation of PROM under real-life clinical conditions.

RESUMEN

BACKGROUND: The desire to be at home is one of the most important needs of patients with advanced, incurable cancers. However, palliative cancer patients may require inpatient hospital care for medical reasons. Virtual reality (VR) could provide an approximation to the individuals' home environment. METHODS: The project consists of 3 parts. All parts are supported by the patient advisory board. In the 1st part of the project, we interview patients, relatives, and the patient advisory board about their wishes and concerns regarding the project. In the 2nd part of the project, patients are offered to view 360° VR videos of their choice (their home, relatives, others if applicable). Effects and side-effects of the intervention are assessed with validated instruments (MIDOS, MDBF, SSQ, SPES). Diagnosis, treatment adherence, medication, and vegetative functionality is determined from the medical records of the patients. In the 3rd part of the project, the results of the study will be discussed with patients, relatives, health care professionals and the patient advisory board regarding implementation. DISCUSSION: This study is the first to investigate whether individualized VR videos have additional benefits over generic VR nature videos on symptom relief, well-being, treatment satisfaction, and adherence in patients with palliative cancer care. A strength of the study is that we can incorporate the results of each part of the project into the subsequent project parts. However, the generalizability might be limited as this is a single-centred study. TRIAL REGISTRATION: Registered at German Clinical Trials Register (Deutsches Register Klinischer Studien; DRKS); registration number: DRKS00032172; registration date: 11/07/2023 https://drks.de/search/de/trial/DRKS00032172 .

RESUMEN

PURPOSE: Guidelines recommend a structured symptom screening (SC) for especially advanced cancer patients (CPs). The aim of this multicenter German prospective quality assurance project KeSBa (Kennzahl Symptom- und Belastungserfassung) was to gain knowledge on SC procedures in Oncology Centers (OCs) for advanced cancer patients and a first impression on the consequences of SC. METHODS: The KeSBa project consisted of three phases: pilot, 3 months screening and feedback phase. Participating OCs decided to use either the Minimal Documentation System (MIDOS) or the Integrated Palliative care Outcome Scale (IPOS) and defined the cutoff values for positive screening results. RESULTS: Out of 172 certified German OCs, 40 (23%) participated in the KeSBa pilot phase, 29 (16.8%) in the 3 months screening phase using MIDOS (n = 18, 58.6%) or IPOS (n = 11, 41.3%) and in the feedback round. 25/29 performed paper-based screening (86.2%). 2.963 CPs were screened. Results were documented for 1255 (42.2%, SC +) positive and 874 (29.5%, SC-) negative screenings depending on the center´s schedules: 452 SC + CPs (28.4%) and 42 SC- CPs (2.6%) had contact to specialized palliative care or other supportive specialist teams afterwards, 458 SC + CPs (28.8%) and 605 SC- CPs (38.1%) remained in standard oncology care. In the feedback round missing resources (personal and IT) and improved communication were mentioned most often. CONCLUSION: Routine SC is feasible in advanced CPs treated in OCs but associated with considerable workload. In 42.2% of CPs SC was classified as positive, indicating the need of further diagnostics or professional judgment. SC requires staff and IT resources.

RESUMEN

PURPOSE: We conducted an international survey of bereaved relatives of cancer patients dying in hospitals in seven countries, with the aim to assess and improve the quality of care. The survey used the i-CODE (International Care of the Dying Evaluation) questionnaire. Here, we report findings from the free-text comments submitted with the questionnaires. We explored for topic areas which would potentially be important for improving the quality of care. Further, we examined who reported free-texts and in what way, to reduce bias without ignoring the function the free-texts may have for those contributing. METHODS: We used a combined qualitative-quantitative approach: logistic regression analysis to study the effect of respondents' socio-demographic characteristics on the probability of free-texts contributions and thematic analysis to understand the free-text meaning. The primary survey outcomes, (1) how frequently the dying person was treated with dignity and respect and (2) support for the relative, were related to free-text content. RESULTS: In total, 914 questionnaires were submitted; 457/914 (50%) contained free-text comments. We found no socio-demographic differences between the respondents providing free-texts and those who did not. We discovered different types of free-texts ("feedback," "narrative," "self-revelation") containing themes of which "continuity of care," "the one person who can make a difference," and "the importance of being a companion to the dying" represent care dimensions supplementing the questionnaire items. A free-text type of grateful feedback was associated with well perceived support for the relative. CONCLUSION: Bereaved relatives used the free-texts to report details related to i-CODE items and to dimensions otherwise not represented. They highlighted the importance of the perceived support from human interaction between staff and the dying patient and themselves; and that more than professional competence alone, personal, meaningful interactions have profound importance.

RESUMEN

During humanitarian crises, such as a pandemic, healthcare systems worldwide face unknown challenges. This study aimed to explore and describe the effect of the SARS-CoV-2 pandemic on the needs of non-infected patients and family caregivers in specialist palliative care, using qualitative, semi-structured interviews. Data were analyzed using inductive content analysis, following the framework approach. Thirty-one interviews were conducted with patients/family caregivers (15/16) in palliative care units/specialist palliative home care (21/10) from June 2020 to January 2021. Well-known needs of patients and family caregivers at the end of life remained during the pandemic. Pandemic- dependent themes were (1) implications of the risk of contagion, (2) impact of the restriction of social interactions, (3) effects on the delivery of healthcare, and (4) changes in the relative's role as family caregiver. Restriction on visits limited family caregivers' ability to be present in palliative care units. In specialist palliative home care, family caregivers were concerned about the balance between preserving social contacts at the end of life and preventing infection. Specialist palliative care during a pandemic needs to meet both the well-known needs at the end of life and additional needs in the pandemic context. In particular, attention should be given to the needs and burden of family caregivers, which became more multifaceted with regards to the pandemic.

RESUMEN

BACKGROUND: The Surprise Question ('Would I be surprised if this patient died within 12 months?') identifies patients in the last year of life. It is unclear if 'surprised' means the same for each clinician, and whether their responses are internally consistent. AIM: To determine the consistency with which the Surprise Question is used. DESIGN: A cross-sectional online study of participants located in Belgium, Germany, Italy, The Netherlands, Switzerland and UK. Participants completed 20 hypothetical patient summaries ('vignettes'). Primary outcome measure: continuous estimate of probability of death within 12 months (0% [certain survival]-100% [certain death]). A threshold (probability estimate above which Surprise Question responses were consistently 'no') and an inconsistency range (range of probability estimates where respondents vacillated between responses) were calculated. Univariable and multivariable linear regression explored differences in consistency. Trial registration: NCT03697213. SETTING/PARTICIPANTS: Registered General Practitioners (GPs). Of the 307 GPs who started the study, 250 completed 15 or more vignettes. RESULTS: Participants had a consistency threshold of 49.8% (SD 22.7) and inconsistency range of 17% (SD 22.4). Italy had a significantly higher threshold than other countries (p = 0.002). There was also a difference in threshold levels depending on age of clinician, for every yearly increase, participants had a higher threshold. There was no difference in inconsistency between countries (p = 0.53). CONCLUSIONS: There is variation between clinicians regarding the use of the Surprise Question. Over half of GPs were not internally consistent in their responses to the Surprise Question. Future research with standardised terms and real patients is warranted.

RESUMEN

BACKGROUND/AIMS: The aim of this study is to investigate the acceptance and benefits of two different strategies to timely integrate specialist palliative care (SPC) in routine cancer care: commonly recommended early SPC counselling versus an informational brochure plus SPC counselling upon patients' request. METHODS: Patients diagnosed with incurable cancer within the last 6-12 weeks were sequentially randomized. Endpoints were acceptance of the two strategies after 3 months as well as the use of SPC counselling and psychosocial support, presence of advance directives, palliative care outcome (Integrated Palliative care Outcome Scale [IPOS]), and psychosocial distress (Distress Thermometer [DT]) after 3 and 6 months. In a qualitative part, SPC consultations were analyzed using a content analysis. RESULTS: Overall, 43 patients received SPC counselling and 37 a brochure with SPC counselling on demand. In the brochure group, only one patient later registered for SPC counselling from own initiative. SPC timing was appropriate in 70% of patients (75% counselling/61% brochure, n.s.). Sufficiency, helpfulness and relevance of information, provision of security, and help with finding contacts for specific support were perceived adequate in both groups. No significant differences were found regarding potential effects of the interventions on IPOS or DT after 3 and 6 months. The use of psychosocial support was comparable between the groups and 4 patients had new advance directives (3 counselling/1 brochure). Five key themes of SPC consultations were identified: symptoms, rapport, coping, illness understanding, and advance care planning. CONCLUSIONS: Both SPC integration strategies were well accepted. However, patients seem not to benefit from a brochure in terms of initiating SPC counselling timely after a palliative cancer diagnosis.

RESUMEN

Background: Demographic change and the medical imperative to accompany patients at all times and also in the case of illness leading to death require good basic knowledge of palliative care in large parts of the medical profession. Palliative care has been introduced into undergraduate medical education as a compulsory subject: "interdisciplinary subject 13 palliative care" (Q13). While course concepts for Q13 have already been positively evaluated, assessment of the consolidation and practical relevance of the knowledge taught is lacking. Methods: Assessment of the consolidation of the learning content from Q13 after the practical year (the "practical year" is the sixth and final year of undergraduate medical education in Germany) by means of a survey with a proven questionnaire and integrated qualitative free-text analysis of a cohort of medical students (n=176) who had already participated in an evaluation before and after Q13. Results: The response rate was 96% after Q13 and 45% after the practical year (PY). Teaching was predominantly perceived as more helpful than the PY (p<0.001). Compared to the status after Q13, students rated themselves as less competent after the PY in all areas surveyed, including drug-based pain therapy (p=0.0386). The certainty in informing patients about the incurability of the disease also decreased significantly after the PY (p=0.0117), although the preparation in Q13 was positively highlighted. Conclusion: The knowledge acquired in Q13 could not be anchored in the PY. On the contrary, after initial practical experiences, the students found it challenging to conduct conversations in cases of serious illness and to deal with their own uncertainty in the care of seriously ill patients. Structural factors regarding palliative care in the PY, as well as intrinsic motives of students, such as prior knowledge or motivation to learn, should be analyzed to identify ways to close the gap between theoretical and practical training in general palliative care. To generate samples that are sufficiently representative, future studies on teaching should be easily accessible to students and consider attractive forms of evaluation including electronic methods and social media.

RESUMEN

Poor communication contributes to morbidity and mortality, not only in general medical care but also at the end oflife. This leads to issues relating to symptom control and quality of care. As part of an international project focused on bereaved relatives' perceptions about quality of end-of-life care, we undertook a quality improvement (QI) project in a general hospital in Córdoba city, Argentina.By using two iterative QI cycles, we launched an educational process and introduced a clinical mnemonic tool, I-PASS, during ward handovers. The introduction of the handover tool was intended to improve out-of-hours care.Our clinical outcome measure was ensuring comfort in at least 60% of dying patients, as perceived by family carers, during night shifts in an oncology ward during the project period (March-May 2019). As process-based measures, we selected the proportion of staff completing the I-PASS course (target 60%) and using I-PASS in at least 60% of handovers. Participatory action research was the chosen method.During the study period, 13/16 dying patients were included. We received 23 reports from family carers about the level of patient comfort during the previous night.Sixty-five per cent of healthcare professionals completed the I-PASS training. The percentage of completed handovers increased from 60% in the first Plan-Do-Study-Act (PDSA) cycle to 68% in the second one.The proportion of positive reports about patient comfort increased from 63% (end of the first PDSA cycle) to 87% (last iterative analysis after 3 months). Moreover, positive responses to 'Did doctors and nurses do enough for the patient to be comfortable during the night?' increased from 75% to 100% between the first and the second QI cycle.In conclusion, we achieved the successful introduction and staff training for use of the I-PASS tool. This led to improved perceptions by family carers, about comfort for dying patients.

RESUMEN

BACKGROUND: Recognized disparities in quality of end-of-life care exist. Our aim was to assess the quality of care for patients dying from cancer, as perceived by bereaved relatives, within hospitals in seven European and South American countries. MATERIALS AND METHODS: A postbereavement survey was conducted by post, interview, or via tablet in Argentina, Brazil, Uruguay, U.K., Germany, Norway, and Poland. Next of kin to cancer patients were asked to complete the international version of the Care Of the Dying Evaluation (i-CODE) questionnaire 6-8 weeks postbereavement. Primary outcomes were (a) how frequently the deceased patient was treated with dignity and respect, and (b) how well the family member was supported in the patient's last days of life. RESULTS: Of 1,683 potential participants, 914 i-CODE questionnaires were completed (response rate, 54%). Approximately 94% reported the doctors treated their family member with dignity and respect "always" or "most of the time"; similar responses were given about nursing staff (94%). Additionally, 89% of participants reported they were adequately supported; this was more likely if the patient died on a specialist palliative care unit (odds ratio, 6.3; 95% confidence interval, 2.3-17.8). Although 87% of participants were told their relative was likely to die, only 63% were informed about what to expect during the dying phase. CONCLUSION: This is the first study assessing quality of care for dying cancer patients from the bereaved relatives' perspective across several countries on two continents. Our findings suggest many elements of good care were practiced but improvement in communication with relatives of imminently dying patients is needed. (ClinicalTrials.gov Identifier: NCT03566732). IMPLICATIONS FOR PRACTICE: Previous studies have shown that bereaved relatives' views represent a valid way to assess care for dying patients in the last days of their life. The Care Of the Dying Evaluation questionnaire is a suitable tool for quality improvement work to help determine areas where care is perceived well and areas where care is perceived as lacking. Health care professionals need to sustain high quality communication into the last phase of the cancer trajectory. In particular, discussions about what to expect when someone is dying and the provision of hydration in the last days of life represent key areas for improvement.

RESUMEN

Palliative care serves to improve the quality of life in patients suffering from incurable diseases. Pharmacotherapy of distressing symptoms plays an important role. Off-label use refers to the use of drugs outside the marketing authorization. In addition to the indications off-label use may also be due to duration of treatment, route of administration and the admixture of substances. Off-label use is common in palliative and hospice care and is probably unavoidable in many cases. For treatment planning and realization of off-label therapy in clinical practice, patient-related aspects, information, therapy monitoring and documentation of therapy effects should be considered in addition to drug-related information. Only in this way it is possible to offer a scientifically adequate, appropriate and economic therapy that is linked to an appropriate risk-benefit ratio for the individual patient. Due to the lack of authorization studies, reporting is of particular importance.

RESUMEN

BACKGROUND: International studies indicate deficits in end-of-life care that can lead to distress for patients and their next-of-kin. The aim of the study was to translate and validate the "Care of the Dying Evaluation" (CODE) into German (CODE-GER). METHODS: Translation according to EORTC (European Organisation for Research and Treatment of Cancer) guidelines was followed by data collection to evaluate psychometric properties of CODE-GER. Participants were next-of-kin of patients who had died an expected death in two hospitals. They were invited to participate at least eight, but not later than 16 weeks after the patient's death. To calculate construct validity, the Palliative care Outcome Scale (POS) was assessed. Difficulty and perceived strain of answering the questionnaire were assessed by a numeric scale (0-10). RESULTS: Out of 1137 next-of-kin eligible, 317 completed the questionnaire (response rate: 27.9%). Data from 237 main sample participants, 38 interraters and 55 next-of-kin who participated for repeated measurement were analysed. Overall internal consistency, α = 0.86, interrater reliability, ICC (1) = 0.79, and retest-reliability, ICC (1, 2) = 0.85, were good. Convergent validity between POS and CODE-GER, r = -.46, was satisfactory. A principal component analysis with varimax rotation showed a 7-factor solution. Difficulty, M = 2.2; SD ± 2.4, and perceived strain, M = 4.1; SD ± 3.0, of completing the questionnaire were rather low. CONCLUSION: The results from the present study confirm CODE-GER as a reliable and valid instrument to assess the quality of care of the dying person. More over our study adds value to the original questionnaire by proposing a deepened analysis of obtained data. The development of seven subscales increases its potential for further surveys and research. TRIAL REGISTRATION: This study was registered retrospectively on the 25th of January 2018 at the German Clinical Trials Register ( DRKS00013916 ).

RESUMEN

BACKGROUND: Patients with multiple myeloma report more problems with quality of life (QoL) than other haematological malignancies over the course of their incurable illness. The patient-centred Myeloma Patient Outcome Scale (MyPOS) was developed to assess and monitor symptoms and supportive care factors in routine care. Our aim was to translate and culturally adapt the outcome measure to the German context, and to explore its face and content validity. METHODS: Translation and cultural adaptation following established guidelines used an exploratory, sequential mixed method study design. Steps included: (1) forward translation to German; (2) backward translation to English; (3) expert review; (4) focus groups with the target population (patients, family members, healthcare professionals) to achieve conceptual equivalence; (5) cognitive interviews using Tourangeau's model with think-aloud technique to evaluate comprehension and acceptability; (6) final review. Results were analysed using thematic analysis. RESULTS: Cultural and linguistic differences were noted between the German and English original version. The focus groups (n = 11) and cognitive interviews (n = 9) both highlighted the need for adapting individual items and their answer options to the German healthcare context. Greater individuality regarding need for information with the right to not be informed was elaborated by patients. While the comprehensive nature of the tool was appreciated, item wording regarding satisfaction with healthcare was deemed not appropriate in the German context. Before implementation into routine care, patients' concerns about keeping their MyPOS data confidential need to be addressed as a barrier, whereas the MyPOS itself was perceived as a facilitator/prompt for a patient-centred discussion of QoL issues. CONCLUSION: With adaptations to answer options and certain items, the German version of the MyPOS can help monitor symptoms and problems afflicting myeloma patients over the course of the disease trajectory. It can help promote a model of comprehensive supportive and patient-centred care for these patients.

RESUMEN

A retractable larynx and adaptations of the vocal folds in the males of several polygynous ruminants serve for the production of rutting calls that acoustically announce larger than actual body size to both rival males and potential female mates. Here, such features of the vocal tract and of the sound source are documented in another species. We investigated the vocal anatomy and laryngeal mobility including its acoustical effects during the rutting vocal display of free-ranging male impala (Aepyceros melampus melampus) in Namibia. Male impala produced bouts of rutting calls (consisting of oral roars and interspersed explosive nasal snorts) in a low-stretch posture while guarding a rutting territory or harem. For the duration of the roars, male impala retracted the larynx from its high resting position to a low mid-neck position involving an extensible pharynx and a resilient connection between the hyoid apparatus and the larynx. Maximal larynx retraction was 108 mm based on estimates in video single frames. This was in good concordance with 91-mm vocal tract elongation calculated on the basis of differences in formant dispersion between roar portions produced with the larynx still ascended and those produced with maximally retracted larynx. Judged by their morphological traits, the larynx-retracting muscles of male impala are homologous to those of other larynx-retracting ruminants. In contrast, the large and massive vocal keels are evolutionary novelties arising by fusion and linear arrangement of the arytenoid cartilage and the canonical vocal fold. These bulky and histologically complex vocal keels produced a low fundamental frequency of 50 Hz. Impala is another ruminant species in which the males are capable of larynx retraction. In addition, male impala vocal folds are spectacularly specialized compared with domestic bovids, allowing the production of impressive, low-frequency roaring vocalizations as a significant part of their rutting behaviour. Our study expands knowledge on the evolutionary variation of vocal fold morphology in mammals, suggesting that the structure of the mammalian sound source is not always human-like and should be considered in acoustic analysis and modelling.

RESUMEN

PURPOSE OF REVIEW: The disease-related burden of patients with hematological malignancies is comparable with patients suffering from solid tumors. Palliative care offers relief from suffering independent of type of disease and prognosis. The prevalence of hematological malignancies is expected to increase in the next 20 years because of better therapeutic options with longer survival and because of the aging population. However, patients with hematological malignancies are underrepresented in palliative care as these diseases are associated with special care needs and prognostic uncertainty, which differ from the unambiguity of terminally ill patients with solid tumors. This review describes the recent studies and guidelines addressing the problems in palliative care for patients with hematological malignancies. RECENT FINDINGS: Recent research covers prognostic uncertainty, challenges in terms of the acute death setting, and blood transfusions in the terminally ill as well as interdisciplinary collaboration. In addition to qualitative approaches exploring reasons for these challenges, criteria that indicate the approaching end of life in hematological malignancies were systematically developed and tested. Further, the effectiveness of palliative care addressing the hematopoietic stem cell transplantation setting was further analyzed. SUMMARY: The patients' perspective needs to be involved in future research to examine whether the connotation of 'palliative care' is a barrier for patients, families or healthcare professionals. Communication culture and skills have already been identified as goals for medical training. Further studies should identify the effective elements of palliative care specific for hematological malignancies and develop feasible support models, including informal caregivers.

RESUMEN

BACKGROUND: The Surprise Question (SQ) "would I be surprised if this patient were to die in the next 12 months?" has been suggested to help clinicians, and especially General Practitioners (GPs), identify people who might benefit from palliative care. The prognostic accuracy of this approach is unclear and little is known about how GPs use this tool in practice. Are GPs consistent, individually and as a group? Are there international differences in the use of the tool? Does including the alternative Surprise Question ("Would I be surprised if the patient were still alive after 12 months?") alter the response? What is the impact on the treatment plan in response to the SQ? This study aims to address these questions. METHODS: An online study will be completed by 600 (100 per country) registered GPs. They will be asked to review 20 hypothetical patient vignettes. For each vignette they will be asked to provide a response to the following four questions: (1) the SQ [Yes/No]; (2) the alternative SQ [Yes/No]; (3) the percentage probability of dying [0% no chance - 100% certain death]; and (4) the proposed treatment plan [multiple choice]. A "surprise threshold" for each participant will be calculated by comparing the responses to the SQ with the probability estimates of death. We will use linear regression to explore any differences in thresholds between countries and other clinician-related factors, such as years of experience. We will describe the actions taken by the clinicians and explore the differences between groups. We will also investigate the relationship between the alternative SQ and the other responses. Participants will receive a certificate of completion and the option to receive feedback on their performance. DISCUSSION: This study explores the extent to which the SQ is consistently used at an individual, group, and national level. The findings of this study will help to understand the clinical value of using the SQ in routine practice. TRIAL REGISTRATION: Clinicaltrials.gov NCT03697213 (05/10/2018). Prospectively registered.
