BackgroundHospital-based Palliative Care Consultation Teams (PCCTs) have a consulting role to specialist services at their request. Referral of patients is often late. Early palliative care in oncology has shown its effectiveness in improving quality of life, thereby questioning the “on request” model of PCCTs. Whether this evidence changed practice is unknown. This multicentre prospective cohort study aims to describe the activity and integration of PCCTs at the patient level.MethodsFor consecutive patients newly referred to participating PCCTs, the team collected the following data: circumstances of first referral, problems identified, number of interventions, patient’s survival after first evaluation and place of death.ResultsSeventeen PCCTs based in university hospitals in Paris area, recruited 744 newly referred adult patients, aged 72 ± 15 years, 52% males, and 504(68%) with cancer as primary diagnosis. After 6 months, 548(74%) had died. At first evaluation, 12% patients were outpatients, 88% were inpatients. Symptoms represented the main reasons for referral and problems identified; 79% of patients had altered performance status; 24% encountered the PCCT only once. Median survival (1st-3rd quartile) after first evaluation by the PCCT was 22 (5–82) days for overall patients, and respectively 31 (8–107) days and 9 (3–34) days for cancer versus noncancer patients (p < 0.0001). Place of death was acute care hospital for 51.7% patients, and home or Palliative Care Unit for 35%. Patients referred earlier died more often in PCU.ConclusionThe study provides original data showing a still late referral to the PCCTs in France. Cancer patients represent their predominant activity. The integrated palliative care model seems to emerge besides the “on request” model which originally characterised their missions.Electronic supplementary materialThe online version of this article (doi:10.1186/s12904-017-0209-9) contains supplementary material, which is available to authorized users.
Question addressedIn contrast with pain, dyspnoea is not visible to the general public who lack the corresponding experiential baggage. We tested the hypotheses that the generalised use of face masks to fight SARS-CoV2 dissemination could change this and sensitise people to respiratory health.MethodsGeneral population polling (1012-person panel demographically representative of the adult French population –quota sampling method–; 517 women, 51%). 860 (85%) answered “no” to “treated for a chronic respiratory disease” (“respiratory healthy”, RH) and 152 “yes” (“respiratory disease”, RD). 14% of RH respondents reported having a close family member treated for a chronic respiratory disease (RH-family+ and RH-family−). Respondents described mask-related attitudes, beliefs, inconveniencies, dyspnoea, and changes in their respiratory health vision.ResultsCompliance with masks was high (94.7%). Dyspnoea ranked first among mask inconveniencies (RD 79.3%, RH 67.3%, p=0.013). “Air hunger” was the main sensory dyspnoea descriptor. Mask-related dyspnoea was independently associated with belonging to RH-family+ (Odds Ratio [OR] [95% confidence interval (CI)]: 1.85 [1.16–2.98]) and removing masks to improve breathing (OR 5.21 [3.73–7.28]). It was negatively associated with considering masks effective to protect others (OR]: 0.42 [0.25–0.75]). Half the respondents were more concerned with their respiratory health since wearing masks; 41% reported better understanding patients’ experiences.Answer to the questionWearing protective face masks leads to the mass discovery of breathing discomfort. It raises the public's awareness of what respiratory diseases involve and sensitises to the importance of breathing. These data should be used as the fulcrum of respiratory-health-oriented communication actions.
In healthy humans, inspiratory threshold loading deteriorates cognitive performances. This can result from motor-cognitive interference (activation of motor respiratory-related cortical networks vs. executive resources allocation), sensory-cognitive interference (dyspnea vs. shift in attentional focus), or both. We hypothesized that inspiratory loading would concomitantly induce dyspnea, activate motor respiratory-related cortical networks, and deteriorate cognitive performance. We reasoned that a concomitant activation of cortical networks and cognitive deterioration would be compatible with motor-cognitive interference, particularly in case of a predominant alteration of executive cognitive performances. Symmetrically, we reasoned that a predominant alteration of attention-depending performances would suggest sensory-cognitive interference. Twenty-five volunteers (12 men; 19.5-51.5 years) performed the Paced Auditory Serial Addition test (PASAT-A and B; calculation capacity, working memory, attention), the Trail Making Test (TMT-A, visuospatial exploration capacity; TMT-B, visuospatial exploration capacity and attention), and the Corsi block-tapping test (visuospatial memory, short-term and working memory) during unloaded breathing and inspiratory threshold loading in random order. Loading consistently induced dyspnea and respiratory-related brain activation. It was associated with deteriorations inPASAT A (52 [45.5;55.5] (median [interquartile range]) to 48 [41;54.5], p=0.01), PASAT B (55 [47.5;58] to 51 [44.5;57.5], p=0.01), and TMT B (44s [36;54.5] to 53s [42;64], p=0.01), but did not affect TMT-A and Corsi. The concomitance of cortical activation and cognitive performance deterioration is compatible with competition for cortical resources (motor-cognitive interference), while the profile of cognitive impairment (PASAT and TMT-B but not TMT-A and Corsi) is compatible with a contribution of attentional distraction (sensory-cognitive interference). Both mechanisms are therefore likely at play.
Background: More than a symptom, dyspnoea is an existential experience shaping the lives of those afflicted, particularly when its persistence despite maximal pathophysiological treatments makes it pervasive. It is, however, insufficiently appreciated by concerned people themselves, family members, healthcare professionals and the public (dyspnoea invisibility), limiting access to appropriate care and support. Aim: To provide a better understanding of dyspnoea experiences and its invisibility. Design: Interpretative phenomenological analysis of data collected prospectively through in-depth semi-structured interviews. Setting/Participants: Pulmonary rehabilitation facility of a tertiary care university hospital; 11 people (six men, five women) with severe chronic obstructive pulmonary disease (stages 3 and 4 of the 4-stage international GOLD classification) admitted for immediate post-exacerbation rehabilitation. Results: We identified several types of dyspnoea invisibility depending on temporality and interlocutors: (1) invisibility as a symptom to oneself; (2) invisibility as a symptom to others; (3) invisibility as an experience that cannot be shared; (4) invisibility as an experience detached from objective measurements; (5) invisibility as an experience that does not generate empathic concern. The notion of invisibility was present in all the identified experiential dimensions of dyspnoea. It was seen as worsening the burden of the disease and as self-aggravating through self-isolation and self-censorship. Conclusions: The study confirmed that dyspnoea invisibility is a reality for people with advanced chronic obstructive pulmonary disease. It shows dyspnoea invisibility to be a multifaceted burden. Future research should aim at identifying individual and collective measures to overcome dyspnoea invisibility.
Dyspnoea-targeted interventions should probably combine multiple approaches (multidirectional) and their evaluation should take the complex nature of dyspnoea into account (multidimensional) http:// ow.ly/tLaM30ndprk

Background Dyspnea is a frightening and debilitating experience. It attracts less attention than pain (‘dyspnea invisibility’), possibly because of its non-universal nature. We tested the impact of self-induced experimental dyspnea on medical residents. Materials and Methods During a teaching session following the principles of experiential learning, emergency medicine residents were taught about dyspnea theoretically, observed experimental dyspnea in their teacher, and personally experienced self-induced dyspnea. The corresponding psychophysiological reactions were described. Immediate and 1-year evaluations were conducted to assess course satisfaction (overall 0–20 grade) and the effect on the understanding of what dyspnea represents for patients. Results Overall, 55 emergency medicine residents participated in the study (26 men, median age 26 years). They were moderately satisfied with previous dyspnea teaching (6 [5–7] on a 0–10 numerical rating scale [NRS]) and expressed a desire for an improvement in the teaching (8 [7–9]). Immediately after the course they reported improved understanding of patients’ experience (7 [6–8]), which persisted at 1 year (8 [7–9], 28 respondents). Overall course grade was 17/20 [15–18], and there were significant correlations with experimental dyspnea ratings (intensity: r = 0.318 [0.001–0.576], p = 0.043; unpleasantness: r = 0.492 [0.208–0.699], p = 0.001). In multivariate analysis, the only factor independently associated with the overall course grade was ‘experiential understanding’ (the experimental dyspnea-related improvement in the understanding of dyspneic patients’ experience). A separate similar experiment conducted in 50 respiratory medicine residents yielded identical results. Conclusions This study suggests that, in advanced medical residents, the personal discovery of dyspnea can have a positive impact on the understanding of what dyspnea represents for patients. This could help fight dyspnea invisibility.
