Assessing the implementation and effectiveness of early integrated palliative care in long-term care facilities in France: an interventional mixed-methods study protocol.

BACKGROUND: Majority of residents in long-term care facilities (LTCF) have limited and delayed access to palliative care even though many suffer from incurable chronic illnesses that will likely require the provision of palliative care. We present the study protocol of "PADI-Palli", an intervention aims to advance early integrated palliative care into standard care delivered in LTCF. This study will assess the effectiveness of early integrated palliative care on palliative care accessibility for older persons in LTCF, and identify the key factors for the successful implementation of early integrated palliative care and its sustainability in the LTCF context. METHODS: This multicentre interventional study utilises a pragmatic research design with a convergent parallel mixed-methods approach. The qualitative study will use a case study design and the quantitative study will use a stepped wedge cluster randomised trial. In total, 21 participating LTCF from three French regions will be randomly allocated to one of seven clusters. The clusters will cross over from the usual care to the active intervention condition over the course of the study. The primary outcome relates to the accurate identification of palliative care needs and early access to palliative care for LTCF residents. Secondary outcomes are quality of care, quality of life for residents and their families, and quality of life at work for professionals. Measurements will be performed before and after the intervention. Implementation and evaluation of PADI-Palli intervention is grounded in the Consolidated Framework for Implementation Research. DISCUSSION: Existing evidence demonstrates that early integrated palliative care in cancer care leads to a significant improvement in patient outcomes and processes of care. Little is known, however, about early integrated palliative care in the context of LTCF for older persons. This study has the potential to fill this gap in the literature by providing evidence on the effectiveness of early integrated palliative care for older persons in LTCF. Moreover, this study will provide a better understanding of the relevant contextual elements that facilitate or hinder early integrated palliative care implementation and transferability. If proven effective, this intervention can be scaled to other care settings in which older persons require palliative care.

Psychometric Properties of the 'Patients' Perspective of the Quality of Palliative Care Scale'.

Objectives: Palliative care is a basic human right for all patients suffering from progressive and excruciating pain, limitations in daily activities as well as requiring constant care. The development of palliative care is always associated with the physical, psychological, social and spiritual care quality level and requires continuous evaluation by the care-receiving patients. This study aimed to determine the psychometric properties of the patients' perspective of the quality of palliative care scale. Materials and Methods: This methodological study was conducted on 500 patients with chronic diseases admitted to the hospitals affiliated in Golestan University of Medical Sciences, between 2019 and 2020. Participants were selected through stratified sampling through proportional allocation as well as considering the bed occupancy rate in the two referral hospitals of the university. According to Wild approach, we translated the original version of the scale the patients' perspectives of the quality of the palliative care scale with 35 items and eight subscales. Using exploratory and confirmatory factor analysis, the psychometric properties of the scale (i.e., initial reliability and face, content, convergent and construct validities) were assessed. The reliability of the scale was calculated by applying Cronbach's alpha coefficient, McDonald's omega coefficient and the Intraclass correlation coefficient (ICC). SPSS-16 and AMOS-24 software programs were used to analyse the data. Results: Three items were omitted after assessing the initial reliability of the translated version of the perspectives of the quality of the palliative care scale using adjusted Cronbach's alpha. The qualitative face validity and impact score of the remaining items of the scale were confirmed by the target group. Meanwhile, a panel of experts confirmed the content validity ratio and content validity index. Convergent validity was approved by calculating the average variance extracted >0.5. Performing EFA led to the extraction of 7 subscales with 32 items. CFA and goodness of fit indices such as GFI = 0.98, CFI = 0.91, RMSEA = 0.048 and GFI = 0.97 confirmed the construct model by omitting three items. Hence, the Persian version of the patient's perspective of the quality of palliative care scale was finalised, including seven subscales with 29 items. ICC of >0.7 represented good reliability. Moreover, Cronbach's alpha and McDonald's omega coefficient confirmed the internal consistency of the scale. Conclusion: Based on the findings of this study, the Persian version of the patients' perspective of the quality of palliative care scale is introduced as a valid and reliable scale. It can accurately indicate and predict the meticulous quality of such care in hospitalised patients and can be used in the cure and care assessments in the health system.

Development and validation of a French questionnaire concerning patients' perspectives of the quality of palliative care: the QUALI-PALLI-Patient.

BACKGROUND: Indicators for the quality of palliative care are a priority of caregivers and managers to allow improvement of various care settings and their comparison. The involvement of patients and families is of paramount, although this is rarely achieved in practice. No validated assessment tools are available in French. Simple cultural adaption of existing questionnaires may be insufficient, due to the varying organization of care in different countries. The purpose of this study was to develop and validate a new instrument to measure the quality of palliative care and satisfaction from the patient point of view. METHODS: Results from a qualitative study were used by a multi-professional workgroup to construct an initial set of 42 items exploring six domains. A cross-sectional survey was conducted in seven hospitals, encompassing three care settings: two palliative care units, one palliative care hospital, and four standard medical units with a mobile palliative care team. All items were assessed for acceptability. We conducted exploratory structural analysis using Principal Component Analysis (PCA), and evaluated external validity by comparison against global rating of satisfaction and the MD Anderson Symptom Inventory (MDASI) questionnaire. RESULTS: A total of 214 patients completed the questionnaire. After removing 7 items from the response distribution, PCA identified eight interpretable domains from the 35 final items: availability of caregivers, serenity, quality of information, pain management, caregivers' listening skills, psychosocial and spiritual aspects, possibility to refuse (care or volunteers), and respect for the patient. Internal consistency was good or acceptable for all subscales (Cronbach's α 0.5-0.84), except the last one (0.15). Factorial structure was found globally maintained across subgroups defined by age, sex, Palliative Performance Scale (PPS ≥ 60%, 40-50% and ≤ 30%), and care settings. General satisfaction was inversely correlated with the 2 scores of the MDASI questionnaire: symptoms' severity and impact on life. Each subscale, except "possibility to refuse", correlated with general satisfaction. CONCLUSIONS: Quali-Palli-Pat appears to be a valid, reliable, and well-accepted French tool to explore the quality of care and the satisfaction of palliative care patients. It should be confirmed in a wider sample of care settings. TRIAL REGISTRATION: clinicaltrials.gov NCT02814682 , registration date 28.6.2016.

The Fami-life study: protocol of a prospective observational multicenter mixed study of psychological consequences of grieving relatives in French palliative care units on behalf of the family research in palliative care (F.R.I.P.C research network).

BACKGROUND: Grieving relatives can suffer from numerous consequences like anxiety, depression, post-traumatic stress disorder (PTSD) symptoms, and prolonged grief. This study aims to assess the psychological consequences of grieving relatives after patients' death in French palliative care units and their needs for support. METHODS: This is a prospective observational multicenter mixed study. Relatives of adult patients with a neoplasia expected to be hospitalized more than 72 h in a palliative care unit for end-of-life issues will be included within 48 h after patient admission. End-of-life issues are defined by the physician at patient admission. Relatives who are not able to have a phone call at 6-months are excluded. The primary outcome is the incidence of prolonged grief reaction defined by an ICG (Inventory Complicate Grief) > 25 (0 best-76 worst) at 6 months after patient' death. Prespecified secondary outcomes are the risk factors of prolonged grief, anxiety and depression symptoms between day 3 and day 5 and at 6 months after patients' death based on an Hospital Anxiety and Depression score (range 0-42) > 8 for each subscale (minimal clinically important difference: 2.5), post-traumatic stress disorder symptoms 6 months after patient' death based on the Impact of Events Scale questionnaire (0 best-88 worst) score > 22, experience of relatives during palliative care based on the Fami-Life questionnaire, specifically built for the study. Between 6 and 12 months after the patient's death, a phone interview with relatives with prolonged grief reactions will be planned by a psychologist to understand the complex system of grief. It will be analyzed with the Interpretative Phenomenological Analysis. We planned to enroll 500 patients and their close relatives assuming a 25% prolonged grief rate and a 6-month follow-up available in 60% of relatives. DISCUSSION: This study will be the first to report the psychological consequences of French relatives after a loss of a loved one in palliative care units. Evaluating relatives' experiences can provide instrumental insights for means of improving support for relatives and evaluation of bereavement programs.

Palliative sedation challenging the professional competency of health care providers and staff: a qualitative focus group and personal written narrative study.

BACKGROUND: Despite recent advances in palliative medicine, sedating a terminally ill patient is regarded as an indispensable treatment to manage unbearable suffering. With the prospect of widespread use of palliative sedation, the feelings and representations of health care providers and staff (carers) regarding sedation must be carefully explored if we are to gain a better understanding of its impact and potential pitfalls. The objective of the study was to provide a comprehensive description of the opinions of carers about the use of sedation practices in palliative care units (PCU), which have become a focus of public attention following changes in legislation. METHODS: Data were collected using a qualitative study involving multi-professional focus groups with health care providers and staff as well as personal narratives written by physicians and paramedical staff. A total of 35 medical and paramedical providers volunteered to participate in focus group discussions in three Palliative Care Units in two French hospitals and to write personal narratives. RESULTS: Health care provider and staff opinions had to do with their professional stance and competencies when using midazolam and practicing sedation in palliative care. They expressed uncertainty regarding three aspects of the comprehensive care: biomedical rigour of diagnosis and therapeutics, quality of the patient/provider relationship and care to be provided. Focusing on the sedative effect of midazolam and continuous sedation until death, the interviewed health care providers examined the basics of their professional competency as well as the key role played by the health care team in terms of providing support and minimizing workplace suffering. Nurses were subject to the greatest misgivings about their work when they were called upon to sedate patients. CONCLUSIONS: The uncertainty experienced by the carers with regard to the medical, psychosocial and ethical justification for sedation is a source of psychological burden and moral distress, and it has proved to be a major source of suffering in the workplace. Lastly, the study shows the uncertainty can have the positive effect of prompting the care team to devise ways to deal with it.

Patients', family caregivers', and professionals' perspectives on quality of palliative care: a qualitative study.

BACKGROUND: The quality of palliative care is the foremost preoccupation of clinicians, decision-makers, and managers as well as patients and families. Major input from healthcare professionals is required to develop indicators for the quality of palliative care, but the involvement of patients and families is also recognized as essential, even though this is rarely achieved in practice. AIM: The objectives of this study were to identify (1) convergences and divergences in the points of view of different stakeholders (patients, families, healthcare professionals) relative to key elements of the quality of palliative care and (2) avenues for refining existing indicators of quality of palliative care. DESIGN: Cross-sectional qualitative study. SETTING/PARTICIPANTS: There were six settings: two hospital-based palliative care units, one hospice, and three other medical units where a mobile palliative care team intervene. Semi-structured interviews were conducted among 61 patients, families, healthcare professionals, and managers. RESULTS: Four major dimensions of quality of care are deemed critical by patients, their families, and professionals: comprehensive support for the patients themselves, clinical management, involvement of families, and care for the imminently dying person and death. Differences exist between various stakeholders regarding perceptions of some dimensions of quality of care. Avenues for improving current quality of care indicators are identified. CONCLUSION: Our study results can be used to refine or develop quality indicators that truly mirror the points of view of patients and their families and of healthcare professionals.

Death wishes and explicit requests for euthanasia in a palliative care hospital: an analysis of patients files.

BACKGROUND: In the current public debate in France about end-of-life and legalization of euthanasia, palliative care is considered as a suitable answer or an alternative or even a supplement to euthanasia. The debate is based on opinion surveys, partly because there is a lack of objective data about the incidence of euthanasia requests (ER) in palliative care settings. The aim of this study was to collect, classify and quantify the expressions of wishes to die (WD), based on computerized files for patients admitted to an 81-bed palliative care hospital (PCH) in Paris during 2010-2011. METHODS: Two researchers analyzed the carers' notes extracted on the basis of containing the words "wish to die", "euthanasia" or any expressions relating to death. Notes related to WD and the corresponding patients were then classified in the order: ER, suicidal thought (ST) and other wish to die (OWD). Repeated ER were qualitatively analyzed according to a grid. RESULTS: We found that 195 of the 2157 patients (9%) expressed a WD: 61 (3%) expressed an ER; 15 (1%) described ST and 119 (6%) expressed an OWD without requiring acting. The WD group was predominantly female, stayed longer in the hospital (median 24 vs. 13 days), and consumed more anxiolytics and antidepressants. None of age, disease or marital status was associated with ER. More women and widows expressed an OWD. Twenty-six ER patients also expressed an OWD and two a ST. Six patients repeated their ER: all had poorly controlled symptoms with repercussions for their mental state. CONCLUSION: Our data show the existence of various expressions of WD with a low incidence of ER in a French PCH. The observation of WD including ER is suggestive of good communication between the patients and the care teams. Independent of the changeability of expressions of WD, their very existence should lead to a consideration of the dynamic changes in these WD, and to care staff paying additional attention to the individual, their suffering and the context.

Understanding why patients request euthanasia when it is illegal: a qualitative study in palliative care units on the personal and practical impact of euthanasia requests.

CONTEXT: Some patients in palliative care units request euthanasia regardless of legislation. Although studies have explored the reasons for these requests, little is known about the subjective, relational, and contextual repercussions for the patient. OBJECTIVES: The aim of this study is to understand the purpose of euthanasia requests from the patient's viewpoint and their personal and practical impact. METHODS: We conducted in-depth interviews with patients requesting euthanasia, their family members, and health care providers in 11 French palliative care units. A thematic analysis of the data was performed. RESULTS: In total, 18 patients were interviewed within 48 h of the request being made; 1 week later, 9 patients were interviewed again. Five main themes emerged: assuming the possibility of transgressing the forbidden, a call for unbearable suffering to be recognized, encouragement to change clinical practice, reclaiming a sense of freedom over medical constraints, and imagining a desirable future for oneself. CONCLUSIONS: A request for euthanasia appears to be a willful means to remove oneself from the impasse of an existence paralyzed by suffering. It creates a space for discussion, which promotes negotiation with patients on care practices and therapeutics, and strengthens patients' sense of autonomy. Investigating the relationship between the evolution of euthanasia requests within the palliative care setting could be beneficial. It is important to encourage health care professionals to adopt a readiness to listen by interacting with patients in a way that is not momentarily action-oriented but rather focused on proactive discussion.

Development and Validation of the QUALI-PALLI-FAM Questionnaire for Assessing Relatives' Perception of Quality of Inpatient Palliative Care: A Prospective Cross-Sectional Survey.

CONTEXT: Relatives of patients receiving palliative care are at risk for psychological and physical distress, and their perception of quality of care can influence patients' quality of life. OBJECTIVES: The purpose of this study was to develop and validate the QUALI-PALLI-FAM questionnaire (QUAlity of PALLIative car from FAMilies' perspective) to measure families' perception of and satisfaction with palliative care. METHODS: An exploratory factor analysis was conducted, and we evaluated the questionnaire's internal consistency using Cronbach's alpha, its stability across various strata, and the correlation between the QUALI-PALLI-FAM (factors, total score, and global satisfaction) and the total score of the FAMCARE (FAMily satisfaction with CARE) questionnaire. RESULTS: This multicentric prospective cross-sectional survey was conducted in seven French hospitals, namely, three palliative care units and four standard medical units with a mobile palliative care team. The questionnaire was completed by 170 relatives of patients (more than 90% of patients had advanced cancer). The final questionnaire included 14 items across three domains: organization of care and availability of caregivers, medical information provision, and confidence and involvement of relatives. Internal consistency was good for all subscales (Cronbach's α = 0.74-0.86). Our questionnaire was stable across various strata: age and gender (patients and relatives), Palliative Performance Scale scores, and care settings. The QUALI-PALLI-FAM total score was correlated with the total FAMCARE score. CONCLUSION: The QUALI-PALLI-FAM appears to be a valid, reliable, and well-accepted tool to explore relatives' perception of quality of inpatient palliative care and complements the QUALI-PALLI-PAT questionnaire. Further testing is required in various settings and countries.

When and how to provide a palliative sedation in terminally ill patients? / Quand et comment mettre en place une sédation à visée palliative en fin de vie ?

When and how to provide a palliative sedation in terminally ill patients? With the introduction in the French law of sedatives practices, the professionals in palliative care are obliged to define the concepts, to name the difference kinds of sedations, to elaborate guidelines for good practice. French society of palliative care has worked to clarify the vocabulary, and to differentiate palliative sedations to their duration, their depth and the patient's consent (typology SEDAPALL). Its guidelines of 2010 have been updated in the form of three reference sheets in conjunction with a continuous deep sedation until death: how to estimate that the vital prognosis is short term? How to evaluate the refractory suffering? What are the guidelines for the pharmacological administration? The French National Authority for Health has produced a guide titled "How to realise a continuous deep sedation until death?" The present paper highlights some fundamental points of necessary steps: listening, understanding and analysing the suffering; the collegiate procedure - multi professional deliberative process, the pharmacological administration.

Quand et comment mettre en place une sédation à visée palliative en fin de vie ? L'introduction dans la loi des pratiques sédatives a obligé les professionnels de soins palliatifs à définir les concepts, nommer les différentes formes de sédations, élaborer des guides de bonne pratique. La Société française d'accompagnement et de soins palliatifs s'est efforcée de clarifier le vocabulaire et de différencier les pratiques sédatives à visée palliative selon leur durée, leur profondeur et le consentement du patient (typologie SEDAPALL). Elle a actualisé ses recommandations de 2010 sous forme de trois fiches repères en lien avec une sédation profonde et continue maintenue jusqu'au décès : Comment apprécier qu'un pronostic vital est engagé à court terme ? Comment évaluer le caractère réfractaire d'une souffrance ? Quels repères pour une mise en oeuvre médicamenteuse ? La Haute Autorité de santé élabore un guide intitulé Comment mettre en oeuvre une sédation profonde et continue jusqu'au décès ? Le présent article reprend quelques points fondamentaux des étapes incontournables : l'écoute, la compréhension et l'analyse de la souffrance, la procédure collégiale ­ processus délibératif pluriprofessionnel, la mise en oeuvre pharmacologique.

Sequential occurrence of dyspnea at the end of life in palliative care, according to the underlying cancer.

Dyspnea is a symptom that severely affects the quality of life of terminally ill patients. Its frequency differs considerably between studies. We aimed to characterize the frequency of dyspnea in a palliative care hospital (PCH) and to identify factors predisposing to dyspnea, particularly during the very last days of life, as a function of the underlying disease. Episodes of dyspnea were identified by the computerized extraction of prospectively collected data from the reports of care assistants or from medical observations recorded in the medical files for all stays at our PCH during the last 6 years. There were 6455 hospital stays, 88% ending in the death of the patient; 13,282 episodes of dyspnea were recorded during 2608 hospital stays (40%). Dyspnea was more frequently observed in cases of cancer than in other conditions (RR = 1.30; 95% CI: 1.14-1.48). Pulmonary metastasis increased the risk of dyspnea from 37% to 51% (RR = 1.37; 95% CI: 1.29-1.46). Dyspnea frequency varied with the primary cancer site, from 24% (brain cancer) to 60% (esophageal cancer). The data for cancer patients staying for more than 6 days who subsequently died indicated that 8% of patients experienced dyspnea exclusively during the last 4 days of the life, independently of the site of the primary cancer. Dyspnea during the last few days of life requires systematic assessment. Exclusively terminal dyspnea should be distinguished from more precocious dyspnea, as the pathophysiological mechanisms and treatments of these two forms are probably different.

Interaction of a combination of morphine and ketamine on the nociceptive flexion reflex in human volunteers.

Experimental studies in animals have suggested that a combination of morphine and N-methyl-D-aspartate (NMDA) receptor antagonists may have additive or synergistic analgesic effects. To further study the nature of the interaction between these two classes of analgesic agents, we analyzed the effects of morphine, ketamine and their combination on electrophysiological recordings of the nociceptive flexion RIII reflex in 12 healthy volunteers. Morphine (0.1 mg/kg), ketamine (0.1 mg/kg followed by 4 microg/kg/min) or their combination were administered intravenously according to a double-blind, placebo controlled and cross-over design. The RIII reflex was recorded from the biceps femoris and elicited by electrical stimulation of the sural nerve. The effects of the drugs were tested on: (1) the stimulus-response curves of the reflex up to the tolerance threshold (frequency of stimulation: 0.1Hz); (2) the progressive increase of the reflex and painful sensations (i.e. wind-up phenomenon) induced by a series of 15 electrical stimuli at a frequency of 1Hz (intensity: 20% above threshold). The stimulus-response curve of the nociceptive RIII reflex was significantly reduced after injection of a combination of ketamine and morphine, but was not modified when placebo or each of the active drugs was administered alone. The wind-up of the RIII reflex and painful sensation was not significantly altered after the injection of placebo, ketamine, morphine or their combination. In conclusion, the present electrophysiological results in humans demonstrate a synergistic interaction between morphine and ketamine, which tends to confirm the interest of using this type of combination in the clinical context. The differential effects observed on the recruitment curve and wind-up indicate, however, that the mechanisms of the interaction between opiates and NMDA receptor antagonists are not univocal but depend on the modality of activation of the nociceptive afferents.

[The therapeutic use of D9-tetrahydrocannabinol (dronabinol) in refractory neuropathic pain]. / Utilisation thérapeutique du D9-tétrahydrocannabinol (dronabinol) dans les douleurs neuropathiques réfractaires.

INTRODUCTION: Despite the recent discovery of the potential mechanisms underlying the analgesic effects of cannabis, few clinical studies have so far assessed its analgesic effects, notably in the treatment of chronic non-malignant pain. All the studies used administration of cannabis alone. The aim of this open, pilot, study was to assess the efficacy and side effect profile of oral dronabinol (tetrahydrocannabinol - THC) in the treatment of refractory neuropathic pain. METHODS: Seven patients (3 women/4 men), aged 60 +/- 14 years, suffering from chronic refractory neuropathic pain, received oral THC titrated to the maximum dose of 25 mg/day (mean dose: 15 +/- 6 mg), during an average of 55,4 days (range: 13-128). Various components of pain (continuous, paroxysmal and brush-induced allodynia) were assessed using VAS scores. Health-related Quality of Life (HRQL) was evaluated using the Brief Pain Inventory, and the Hospital Anxiety and Depression scale was used to measure depression and anxiety. RESULTS: THC did not induce significant effect on the various pain, HRQL and anxiety and depression scores. Numerous side effects (notably sedation and asthenia) were observed in 5 patients out of 7, requiring premature discontinuation of the drug in 3 patients. CONCLUSION: The present study did not reveal any significant efficacy of THC in a small cohort of patients with chronic refractory neuropathic pain, but underlined the unfavorable side effect profile of the drug. These results may partly relate to the fact that oral dronabinol exhibits a poor therapeutic ratio (efficacy at the price of side effects). The development of new and better tolerated cannabinoids is warranted.

Recommendations for bowel obstruction with peritoneal carcinomatosis.

This article reports on the clinical practice guidelines developed by a multidisciplinary group working on the indications and uses of the various available treatment options for relieving intestinal obstruction or its symptoms in patients with peritoneal carcinomatosis. These guidelines are based on a literature review and expert opinion. The recommended strategy involves a clinical and radiological evaluation, of which CT of the abdomen is a crucial component. The results, together with an analysis of the prognostic criteria, are used to determine whether surgery or stenting is the best option. In most patients, however, neither option is feasible, and the main emphasis, therefore, is on the role and administration of various symptomatic medications such as glucocorticoids, antiemetic agents, analgesics, and antisecretory agents (anticholinergic drugs, somatostatin analogues, and proton-pump inhibitors). Nasogastric tube feeding is no longer used routinely and should instead be discussed on a case-by-case basis. Recent studies have confirmed the efficacy of somatostatin analogues in relieving obstruction-related symptoms such as nausea, vomiting, and pain. However, the absence of a marketing license and the high cost of these drugs limit their use as the first-line treatment, except in highly selected patients (early recurrence). When these medications fail to alleviate the symptoms of obstruction, venting gastrostomy should be considered promptly. Rehydration is needed for virtually every patient. Parenteral nutrition and pain management should be adjusted according to the patient needs and guidelines.

Cancer-related symptom assessment in France: validation of the French M. D. Anderson Symptom Inventory.

This multicenter study was intended to validate the French version of the M. D. Anderson Symptom Inventory (MDASI-Fr) in French cancer patients (n=162) with solid tumors or hematological malignancies. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) was used as a part of the validation. Factor analysis showed three underlying constructs for symptom items: general symptoms (pain, fatigue, disturbed sleep, shortness of breath, drowsiness, dry mouth, and numbness or tingling items); emotional and cognitive components (distress, sadness, and remembering items); and a gastrointestinal component (nausea, vomiting, and lack of appetite items), with Cronbach's alphas of 0.79, 0.73, and 0.71, respectively. Convergent validity was established by comparing MDASI-Fr items with the EORTC QLQ-C30 scale and the Brief Pain Inventory (BPI). Overall, the 19-item MDASI-Fr score correlated well with the QLQ-C30 global health status, and the pain item of the MDASI-Fr was highly correlated with the short form of the BPI. The most prevalent symptoms were fatigue, distress, dry mouth, and pain. Twenty-five percent of patients reported moderate or severe pain (numeric rating scale >4 on 0-10 severity ratings). Physician ratings of global change on a second visit were significantly associated with changes in patient ratings on the MDASI-Fr, supporting the sensitivity of the measure. Symptoms interfered most with work and general activity. The MDASI-Fr is a valid and reliable tool for measuring symptom severity and interference in French cancer patients.

Comparison of the pain suppressive effects of clinical and experimental painful conditioning stimuli.

Studies in healthy volunteers suggested that the classical counterirritation phenomenon (i.e. pain inhibits pain effect) might depend on diffuse noxious inhibitory controls (DNIC), which modulate the spinal transmission of nociceptive signals. In the present study, we sought to determine whether similar mechanisms were at play in patients with different subtypes of neuropathic pain. Ten patients presenting with a traumatic peripheral nerve injury associated with dynamic mechano-allodynia (i.e. pain triggered by brushing) or static mechano-allodynia (i.e. pain triggered by light pressure stimuli) were included in this study. To investigate counterirritation mechanisms in these patients, we analysed the RIII nociceptive flexion reflex and concomitant painful sensation elicited by electrical stimulation of the sural nerve. We compared the effects of heterotopic 'clinical' conditioning stimuli (i.e. pain evoked by brushing or pressure within the allodynic area located in the upper limb or chest) to those of experimental heterotopic noxious stimuli (HNCS) consisting of a cold pressor test or tourniquet test applied to the normal upper limb. Static mechano-allodynia induced inhibitions of both the RIII reflex and the concomitant painful sensation. These effects were similar to those induced by HNCS and were probably due to an increased activation of DNIC. In contrast, in patients with dynamic allodynia, brushing within the allodynic area reduced the pain sensation at the foot, but did not inhibit the electrophysiological responses, suggesting that in this case the counterirritation effect may take place at the supraspinal level. Thus, the mechanisms of counterirritation are not univocal, but depend on the pathophysiological mechanisms of clinical pain.
