[Primary chronic pain : the lack of recognition for an invisible handicap]. / Douleur chronique primaire : le manque de reconnaissance d'un handicap invisible.

Despite chronic primary pain being recognized as a disease in the 11th revision of the International Classification of Diseases (ICD-11), individuals suffering from it are still too frequently met with a certain skepticism. This skepticism can detrimentally affect their healthcare journey, social life, and economic stability. This article outlines part of the legal evolution regarding the recognition of chronic pain as well as the current insurance-related provisions in Switzerland. With a thorough understanding of this system, physicians can reduce frustration and disputes as well as promoting decision-making processes. The article concludes by highlighting the tools that physicians can use to navigate procedures related to disability insurance effectively.

Malgré une reconnaissance de la douleur chronique primaire comme maladie à part entière dans la 11e révision de la Classification internationale des maladies (CIM), les patient-e-s en souffrant font encore trop fréquemment face à un certain scepticisme. Cela peut leur porter préjudice dans leur parcours de soin, leur vie sociale et leur stabilité économique. Cet article retrace une partie de l'évolution légale de la reconnaissance de la douleur chronique ainsi que les dispositions assécurologiques en vigueur en Suisse. Une bonne connaissance de ce système de la part des médecins peut diminuer la frustration des patient-e-s, les litiges et la lenteur des décisions. Enfin, cet article conclut en proposant des conseils et des outils pour que les médecins puissent accompagner au mieux leurs patient-e-s dans les procédures assécurologiques.

Is Positive Communication Sufficient to Modulate Procedural Pain and Anxiety in the Emergency Department? A Randomized Controlled Trial.

OBJECTIVE: Research suggests that therapeutic communication could enhance patient comfort during medical procedures. Few studies have been conducted in clinical settings, with adequate blinding. Our hypothesis was that a positive message could lead to analgesia and anxiolysis, and that this effect would be enhanced by an empathetic interaction with the nurse performing the procedure, compared with an audio-taped message. This study aimed to modulate the contents and delivery vector of a message regarding peripheral intravenous catheter (PIC) placement in the emergency department (ED). METHODS: This study was a 2 + 2 randomized controlled trial registered on ClinicalTrials.gov (NCT03502655). A positive versus standard message was delivered through audio tape (double-blind) in the first phase ( N = 131) and through the nurse placing the catheter (single-blind) in the second phase ( N = 120). RESULTS: By design, low practitioner empathic behavior was observed in the first phase (median, 1 of 5 points). In the second phase, higher empathic behavior was observed in the positive than in the standard message (median, 2 versus 3, p < .001). Contrary to our hypothesis, the intervention did not affect pain or anxiety reports due to PIC placement in either phase (all p values > .2). CONCLUSIONS: The positive communication intervention did not impact pain or anxiety reports after PIC. There might have been a floor effect, with low PIC pain ratings in a context of moderate pain due to the presenting condition. Hence, such a therapeutic communication intervention might not be sufficient to modulate a mild procedural pain in the ED.

Analgesic and Anxiolytic Effects of Virtual Reality During Minor Procedures in an Emergency Department: A Randomized Controlled Study.

STUDY OBJECTIVE: We aimed to assess the analgesic and anxiolytic efficacy of distraction, a nonpharmacologic intervention provided by 3-dimensional (3D) virtual reality (VR) compared with that provided by 2-dimensional (2D) VR during minor emergency department (ED) procedures. METHODS: This randomized controlled study conducted in the ED of a teaching hospital included patients aged more than or equal to 18 years undergoing minor procedures. The patients watched the same computer-generated VR world either in 3D in a head-mounted display (intervention) or in 2D on a laptop screen (control). Our main outcomes were pain and anxiety during the procedure, assessed on a 100-mm visual analog scale. Secondary outcomes included the impression of telepresence in the computer-generated world assessed using the Igroup Presence Questionnaire, and the prevalence and intensity of cybersickness measured on a 100-mm visual analog scale. RESULTS: The final analysis included 117 patients. The differences in median procedural pain and anxiety levels between the 2D and 3D VR groups were not significant: -3 mm (95% confidence interval [CI] -14 to 8) and -4 mm (95% CI -15 to 3), respectively; the difference in telepresence was 2.0 point (95% CI 0 to 2.0), and the proportion difference of cybersickness was -4% (95% CI -22 to 14), with an intensity difference of -5 mm (95% CI -9 to 3). CONCLUSION: During minor procedures in adult patients in the ED, distraction by viewing a 3D virtual world in a head-mounted VR display did not result in lower average levels of procedural pain and anxiety than that by 2D viewing on a screen despite a higher sense of telepresence. There were no significant differences in the prevalence and intensity of cybersickness between the 2 groups.

Somatosensory profiling of patients undergoing alcohol withdrawal: Do neuropathic pain and sensory loss represent a problem?

INTRODUCTION: Chronic heavy alcohol use is known to cause neurological complications such as peripheral neuropathy. Concerning the pathophysiology, few sural nerve and skin biopsy studies showed that small fibers might be selectively vulnerable to degeneration in alcohol-related peripheral neuropathy. Pain has rarely been properly evaluated in this pathology. The present study aims at assessing pain intensity, potential neuropathic characteristics as well as the functionality of both small and large nerve sensitive fibers. METHODS: In this observational study, 27 consecutive adult patients, hospitalized for alcohol withdrawal and 13 healthy controls were recruited. All the participants underwent a quantitative sensory testing (QST) according to the standardized protocol of the German Research Network Neuropathic Pain, a neurological examination and filled standardized questionnaires assessing alcohol consumption and dependence as well as pain characteristics and psychological comorbidities. RESULTS: Nearly half of the patients (13/27) reported pain. Yet, pain intensity was weak, leading to a low interference with daily life, and its characteristics did not support a neuropathic component. A functional impairment of small nerve fibers was frequently described, with thermal hypoesthesia observed in 52% of patients. Patients with a higher alcohol consumption over the last 2 years showed a greater impairment of small fiber function. DISCUSSION: Patients report pain but it is however unlikely to be caused by peripheral neuropathy given the non-length-dependent distribution and the absence of neuropathic pain features. Chronic pain in AUD deserves to be better evaluated and managed as it represents an opportunity to improve long-term clinical outcomes, potentially participating to relapse prevention.

Hypnosis in the operating room: are anesthesiology teams interested and well-informed?

BACKGROUND: Hypnosis can be a beneficial complementary anesthesia technique for a variety of surgical procedures. Despite favorable scientific evidence, hypnosis is still rarely used in the operating room. Obstacles to implementation could be a lack of interest or training, misconceptions, as well as limited knowledge amongst anesthesiology teams. Hence, this study aimed to assess the interest, training, beliefs, and knowledge about hypnosis in the operating room staff. DESIGN: A questionnaire with 21-items, based on a prior survey, was set up on an online platform. The medical and nursing anesthesiology staff of four Swiss academic and large regional hospitals (N = 754) were invited to participate anonymously through e-mails sent by their hierarchy. Results were analyzed quantitatively. RESULTS: Between June, 2020 and August, 2021 353 answers were collected (47% response rate). Most (92%) were aware that hypnosis needs specific training, with 14% trained. A large majority of the untrained staff wished to enroll for conversational hypnosis training. There was a strong agreement for hypnosis playing a role in anesthesia. Nevertheless, many of these professionals believed that hypnosis has a limited field of action (53%) or that it would be too time consuming (33%). The reduction of misconceptions was based more on exposure to hypnosis than on training. CONCLUSION: Overall, anesthesia providers' attitude was in favor of using hypnosis in the operating room. Misconceptions such as a prolongation of the procedure, alteration of consent, lack of acceptability for patients, and limited indications were identified as potential barriers. These deserve to be challenged through proper dissemination of the recent scientific literature and exposure to practice.

[Tapering of opioid-based pain treatment for chronic pain patients in an outpatient setting]. / Sevrage en ambulatoire d'un traitement par opiacés chez des patients souffrant de douleur chronique.

Caring for chronic pain patients under opioid therapy is challenging. Opioid treatments above 50 milligrams morphine equivalents (MME) per day are associated with an increased risk of morbidity and mortality. A tapering or a discontinuation should be discussed. Shared decision-making with individualized goals and motivational interviewing principles should be used. Tapering should be slow, with initial rate based on the duration of opioid use and with regular monitoring of patients. Inability to taper may require further reassessment of opioid dependence. Temporary increases in pain may occur at the start of tapering, but pain may improve or remain unchanged upon completion of tapering.

La prise en charge des patients souffrant de douleurs chroniques et traités par des opiacés pose souvent un défi aux cliniciens. Les traitements par des opiacés au-delà de 50 milligrammes d'équivalents de morphine (MME) par jour sont associés à des taux de morbidité et mortalité élevés. Une réduction ou un arrêt doivent être discutés. Cette approche doit se faire en collaboration avec le patient, avec des objectifs individualisés, utilisant des principes d'entretien motivationnel. La diminution doit être lente en tenant compte de la durée préalable du traitement et suivie de manière régulière. L'incapacité à réduire progressivement peut nécessiter l'évaluation d'une possible dépendance. Des augmentations temporaires de la douleur peuvent survenir au début de la réduction, mais la douleur peut rester inchangée ou même s'améliorer une fois la réduction terminée.

[Integrative medicine: what's new in 2022]. / Médecine intégrative : ce qui a changé en 2022.

To illustrate the news of 2022, we present first a scientific article on mindfulness: a meta-analysis shows both preventive and therapeutic effects for the pediatric population. A second scientific article is summarized: it investigated acupuncture in an obstetrical context, demonstrating its effectiveness on post-caesarean pain and on functional capacity, by improving early mobilization. Hence, these approaches have an increasing level of scientific evidence in these given fields, calling for a clinical implementation. Finally, we offer a practical summary concerning the prescription of cannabis, especially useful following the abolishment of the obligatory FOPH authorization as of August 1, 2022. Nevertheless, we underline that the evidence for cannabinoids being effective remains weak in most indications.

En termes de nouveautés 2022, nous présentons en premier lieu un article scientifique traitant de la pleine conscience : une méta-analyse montre des effets tant préventifs que thérapeutiques pour la population pédiatrique. Le deuxième article scientifique présenté traite de l'acupuncture dans un contexte obstétrical, démontrant son efficacité sur la douleur postcésarienne et sur la capacité fonctionnelle, en améliorant la mobilisation précoce. Ces deux approches bénéficient donc d'un niveau de preuve scientifique croissant appelant à une implantation clinique. Finalement, nous offrons un résumé pratique concernant la prescription de cannabis, tout particulièrement utile suite à la levée de l'obligation d'autorisation de l'OFSP dès le 1er août 2022. Néanmoins, nous soulignons que les preuves restent faibles concernant l'efficacité des cannabinoïdes dans la plupart des indications.

[Mindfulness meditation in somatic medicine. A management tool for physical and psychological pain]. / Applications de la méditation de pleine conscience dans différents secteurs de médecine somatique. Un outil de gestion de la douleur physique et morale.

Mindfulness meditation is a mind-body approach that helps to cope with psychological or physical symptoms such as pain. To date, this approach is still not widely available to patients in our French-speaking somatic clinical settings, despite its scientific validation. This article describes three mindfulness meditation programs delivered at Lausanne University Hospital (CHUV) to people living with HIV, cancer or chronic pain. It highlights the issues related to the involvement of participants in these programs as well as those related to their implementation in a Swiss somatic, teaching French-speaking hospital.

La méditation de pleine conscience est une approche corps-esprit qui permet de faire face à des symptômes psychiques ou physiques tels que la douleur. À ce jour, malgré sa validation scientifique, cette approche reste peu accessible pour les patient-e-s dans nos contextes cliniques somatiques romands. Cet article décrit trois programmes de méditation de pleine conscience délivrés au sein du CHUV (Lausanne), à des personnes qui vivent avec un VIH, un cancer ou une douleur chronique. Il met en lumière les enjeux liés à l'engagement des participant-e-s dans ces programmes mais aussi ceux en lien avec leur implémentation dans un contexte hospitalier somatique romand.

[Chronic cancer pain: pathophysiology and ICD-11 classification]. / Douleurs chroniques liées au cancer : physiopathologie et classification CIM-11.

Chronic cancer pain is one of the most common symptoms affecting oncology patients and cancer survivors. Epidemiological trends show that its recognition and management are increasingly important. The ICD-11 provides a better analysis of this problem based on the pathophysiological characteristics of cancer-related pain. This article proposes to review the mechanisms of cancer-related pain in relation to this classification.

La douleur chronique liée au cancer est l'un des symptômes les plus fréquents chez les patients oncologiques et survivants d'un cancer. L'évolution épidémiologique montre que sa reconnaissance et sa prise en charge représentent des enjeux grandissants. La CIM-11 (Classification internationale des maladies) permet une meilleure analyse de cette problématique en se basant sur les caractéristiques physiopathologiques de la douleur liée au cancer. Cet article propose de rappeler, à la lumière de cette classification, les mécanismes de la douleur associée à un cancer.

[Cancer pain therapy: beyond conventional pharmacological approaches]. / Traitement de la douleur cancéreuse : au-delà des approches médicamenteuses conventionnelles.

Pain management in oncology is evolving progressively thanks to integrative approaches. In accordance with the type of pain and patient specifics, treatment possibilities are thus multiplied by combining conventional pharmacology, interventional approaches, physical and psychological treatments as well as complementary medicines, in a holistic perspective. International Societies Guidelines and scientific literature lend their support to such treatment plans. This article covers a number of interventional treatments and complementary options that are available. Their relevance is all the more important in view of the necessity to limit secondary effects and long-term opioids, especially in cancer survivors.

La prise en charge de la douleur en oncologie s'enrichit progressivement grâce à une approche intégrative. Celle-ci permet d'élargir la palette des outils thérapeutiques du praticien en combinant, selon les caractéristiques de la douleur et les spécificités du patient, les approches conventionnelles et complémentaires dans une vision holistique du patient. Les recommandations des sociétés internationales et la littérature scientifique s'étayent dans cette direction. Cet article couvre une partie des thérapies interventionnelles et des options complémentaires possibles. Leur pertinence est d'autant plus grande dans l'optique de limiter les effets secondaires des traitements médicamenteux et les opioïdes au long cours, prioritairement chez les patients en rémission ou avec une maladie contrôlée.

[Integrative medicine: scientific literature in 2021]. / Médecine integrative - Littérature scientifique en 2021.

To illustrate the novelties in integrative and complementary medicine in 2021, the authors present a selection of six articles. One of them is specifically related to COVID-19. The other articles deal with themes that are always relevant and where complementary approaches represent a real added value. Two articles focus on low back pain, a common problem in primary care medicine. The others examine acupuncture in the oncological context, the use of therapeutic suggestions in an operative context, and Tai Chi. The authors thus provide an overview of the range of possible complementary therapeutic approaches that are increasingly supported by evidence, inviting them to be better integrated into clinical practice.

Pour illustrer les nouveautés en médecine intégrative et complémentaire en 2021, les auteur·e·s présentent une sélection de six articles. L'un s'intéresse plus spécifiquement au Covid-19. Les autres touchent des thématiques qui restent toujours d'actualité et où des approches complémentaires peuvent représenter une réelle plus-value. Deux articles ont pour thème les lombalgies, problématique courante en médecine de premier recours. Les autres examinent l'acupuncture dans le contexte oncologique, l'utilisation de suggestions thérapeutiques dans un contexte opératoire, et le Tai Chi. Les auteur·e·s donnent ainsi un aperçu de l'éventail d'approches thérapeutiques complémentaires possibles et de plus en plus soutenues par la science, invitant à les intégrer de mieux en mieux dans la pratique clinique.

Are patients with hypermobile Ehlers-Danlos syndrome or hypermobility spectrum disorder so different?

Diagnosing hypermobile Ehlers-Danlos syndrome (hEDS) remains challenging, despite new 2017 criteria. Patients not fulfilling these criteria are considered to have hypermobile spectrum disorder (HSD). Our first aim was to evaluate whether patients hEDS were more severely affected and had higher prevalence of extra-articular manifestations than HSD. Second aim was to compare their outcome after coordinated physical therapy. Patients fulfilling hEDS/HSD criteria were included in this real-life prospective cohort (November 2017/April 2019). They completed a 16-item Clinical Severity Score (CSS-16). We recorded bone involvement, neuropathic pain (DN4) and symptoms of mast cell disorders (MCAS) as extra-articular manifestations. After a standardized initial evaluation (T0), all patients were offered the same coordinated physical therapy, were followed-up at 6 months (T1) and at least 1 year later (T2), and were asked whether or not their condition had subjectively improved at T2. We included 97 patients (61 hEDS, 36 HSD). Median age was 40 (range 18-73); 92.7% were females. Three items from CSS-16 (pain, motricity problems, and bleeding) were significantly more severe with hEDS than HSD. Bone fragility, neuropathic pain and MCAS were equally prevalent. At T2 (20 months [range 18-26]) 54% of patients reported improvement (no difference between groups). On multivariable analysis, only family history of hypermobility predicted (favorable) outcome (p = 0.01). hEDS and HDS patients showed similar disease severity score except for pain, motricity problems and bleeding, and similar spectrum of extra-articular manifestations. Long-term improvement was observed in > 50% of patients in both groups. These results add weight to a clinical pragmatic proposition to consider hEDS/HSD as a single entity that requires the same treatments.

[Contribution of the use of virtual reality in childbirth: A narrative review of the literature]. / Apport de l'utilisation de la réalité virtuelle lors de l'accouchement - Revue narrative de la littérature.

The current use of virtual reality (VR) in medicine is expanding rapidly. This non-pharmacological option is increasingly proposed as primary or complementary/multimodal analgesic or anxiolytic management. The role of VR in obstetrics remains to be defined. We propose a narrative review of the literature on the role of VR in obstetrics during childbirth, which shows promise. If used properly, this technique could help improve the experience of childbirth.

L'usage actuel de la réalité virtuelle (RV) en médecine est en pleine expansion. Cette option non pharmacologique est de plus en plus proposée comme prise en charge antalgique ou anxiolytique principale ou complémentaire/multimodale. La place de la RV en obstétrique reste à définir. Nous proposons ici une revue narrative de la littérature sur la place de la RV en obstétrique lors de l'accouchement, qui se révèle prometteuse. Avec une utilisation bien encadrée, cette technique pourrait avoir sa place dans l'amélioration du vécu de l'accouchement.

[Scientific literature on integrative medicine in 2020]. / Littérature scientifique concernant la médecine intégrative en 202.

Scientific research in integrative medicine has undergone significant development in recent years. Several studies published in 2020 focus on the management of chronic pain. Hypnosis has been shown to be as effective in analgesia as cognitive-behavioral therapy and therapeutic education. A study on chronic low back pain showed lower health care costs for patients using complementary medicine. Furthermore, the hypothesis of super responders to acupuncture treatment does not seem to be confirmed. Yoga could be a useful approach in the prevention of migraines. With respect to the management of COVID-19, the addition of traditional Chinese medicine to conventional treatments could reduce a number of symptoms and the length of hospital stays, although the quality of data is limited.

La recherche en médecine intégrative connaît un développement important depuis quelques années. Plusieurs études publiées en 2020 concernent la prise en charge de la douleur chronique. L'hypnose s'est montrée aussi efficace contre la douleur que la thérapie cognitivo-comportementale et l'éducation thérapeutique. Une étude sur les lombalgies chroniques a indiqué des dépenses de santé plus basses pour les patients recourant aux médecines complémentaires. Par ailleurs, l'hypothèse de super-répondeurs à un traitement d'acupuncture ne semble pas se confirmer. Le yoga pourrait être une approche utile dans la prévention des migraines. En ce qui concerne la prise en charge du Covid-19, l'ajout de la médecine traditionnelle chinoise pourrait diminuer certains symptômes et la durée des hospitalisations, bien que la qualité des données reste limitée.

[Breast cancer: perspectives from integrative medicine]. / Cancer du sein: perspectives de médecine intégrative.

Integrative medicine combines the virtues of conventional medicine and complementary medicine in order to improve the quality of life of patients suffering from cancer. Thanks to a multidisciplinary and multi-professional team, the Center for integrative and complementary medicine (CEMIC) allows since 2017 cancer patients at CHUV to have access to certain therapies, for which there are sufficient data suggesting a benefit in terms of quality of life. The concepts of tolerance, safety, risk of interactions and potential adverse biological effects remain central. In this article, we discuss acupuncture, art therapy, mindfulness and some natural therapies that are encountered regularly.

La médecine intégrative propose aux patients touchés par le cancer une combinaison des soins offerts par la médecine conventionnelle et la médecine complémentaire avec comme objectif l'amélioration de la qualité de vie des patients. Grâce à des équipes multidisciplinaires et multiprofessionnelles, le Centre de médecine intégrative et complémentaire (CEMIC) permet depuis 2017 aux patients oncologiques du CHUV d'avoir accès à certaines thérapies pour lesquelles il existe des données suggérant un bénéfice en termes de qualité de vie. Les notions de tolérance aux traitements, de sécurité, de risque d'interactions et d'éventuels effets biologiques non souhaités restent centrales. Dans cet article, nous discutons de l'acupuncture, de l'art-thérapie, de la méditation et de certaines substances et thérapies naturelles rencontrées régulièrement.

Opioid-Independent and Opioid-Mediated Modes of Pain Modulation.

Pain is regulated endogenously through both opioid and non-opioid mechanisms. We hypothesized that two novel pain modulation tasks, one drawing on context/expectations and one using voluntary reappraisal, would show differing levels of opioid dependence. Specifically, we expected that naloxone would block context-related analgesia, whereas mental imagery-based pain reappraisal would be opioid-independent.A double-blind, placebo-controlled intravenous naloxone versus saline crossover design was used. Twenty healthy volunteers completed the two modulation tasks with acute heat stimuli calibrated to induce moderate pain. In the mental imagery task, participants imagined either a "pleasant" or a "comparison" scenario during painful heat. In the relative relief task, moderate heat stimuli coincided with visual cues eliciting relief from the expectation of intense pain, and were compared with moderate heat stimuli delivered under the expectation of non-painful warmth. Both "pleasant imagery" and "relative relief" conditions significantly improved ratings of pain intensity and pleasantness during saline treatment. Indeed, the target stimuli in both tasks, which had been calibrated to induce moderate pain, were rated as mildly pleasant. Furthermore, consistently with the main hypothesis, blocking endogenous opioid signaling with naloxone did not significantly affect imagery-induced regulation of pain intensity or pleasantness. In contrast, the relative relief-induced pain regulation (i.e., context/expectation) was blocked by naloxone. We conclude that endogenous opioid signaling is necessary for expectation-related relative relief analgesia, but not for pain reappraisal through mental imagery. These results support mental imagery as a powerful and clinically relevant strategy for regulating pain affect also in patients where endogenous opioid mechanisms might be compromised.SIGNIFICANCE STATEMENT Neurotransmitter systems in the human brain can be probed through antagonist drugs. Studies using the opioid antagonist naloxone have demonstrated that the brain relies on both opioid and non-opioid mechanisms to downregulate pain. This holds clinical relevance given altered endogenous opioid processes in many chronic pain conditions. The present study used a double-blinded, placebo-controlled naloxone blockage of endogenous opioids in healthy humans to show differential opioid involvement in two pain modulation tasks. Context/expectation-driven (relative relief-related) analgesia was blocked by naloxone. In contrast, pain reappraisal through mental imagery was intact despite opioid receptor blockade, suggesting opioid independence. These results support mental imagery as a powerful, clinically relevant strategy for regulating pain as it does not rely on a functioning opioidergic system.

[Integrative pain medicine: a holistic view of patients suffering from chronic pain]. / Antalgie intégrative : une vision holistique du patient souffrant de douleurs chroniques.

Integrative medicine can usefully be applied to the care of patients suffering from chronic pain, when there is a good understanding of its framework. Integrative pain management relies on the following principles: considering globally all aspects of the person's life, creating a strong partnership with the patient, choosing treatments both from complementary and conventional medecine as long as they are relying on evidence and prioritizing therapeutic interventions that are the least invasive and costly for equal benefits. This article provides key elements to enhance a pain management plan through a holistic perspective. Amongst other practical tools, it offers a non exhaustive synthesis of validated therapeutic techniques based on recent reviews and clinical guidelines for different pain conditions.

La médecine intégrative peut avantageusement s'appliquer à la prise en charge des personnes souffrant de douleurs chroniques lorsque sa démarche est bien comprise. L'antalgie intégrative s'appuie sur les principes fondamentaux suivants : tenir compte de toutes les sphères de la vie de la personne, créer un partenariat avec elle, ancrer les choix thérapeutiques dans la médecine basée sur les preuves en incluant les médecines complémentaires et conventionnelles, et à efficacité équivalente, choisir en priorité les interventions les moins invasives et les plus économes. Cet article donne des outils pour approcher les patients dans une vision holistique de la personne et étoffer les propositions thérapeutiques antalgiques. Entre autres, une synthèse non exhaustive d'options thérapeutiques validées pour différentes conditions douloureuses est proposée.

[Opioid consumption from 1985 to 2015 : The situation in Switzerland, with an international comparison]. / Consommation d'opioïdes entre 1985 et 2015 : chiffres suisses et mise en perspective internationale.

In North America the massive increase in opioid prescriptions for chronic non-cancer pain has been a major health issue for several years. In Switzerland, the situation is less well known. This article aims to present the evolution of the Swiss consumption and replace it in a European and international context using the International Narcotics Control Board database. Between 1985 and 2015, the Swiss opioid consumption raised from 18 to 421 mg/person/year, making Switzerland the 7th largest opioid consumer per capita in the world. This increase could be due to more adequate pain management or liberalized opioid prescription for indications unsupported by the current evidence. Given these elements, further research is needed, yet increased caution is recommended when prescribing opioid drugs.

En Amérique du Nord, la large prescription d'opioïdes dans le cadre de douleurs chroniques non cancéreuses constitue une problématique majeure de santé publique depuis plusieurs années. La situation en Suisse est moins connue. Cet article vise à présenter l'évolution de la consommation suisse et de la replacer dans un contexte européen et international, en utilisant les données de l'International Narcotics Control Board. La Suisse est le 7e consommateur mondial d'opioïdes par habitant. Entre 1985 et 2015, la consommation suisse d'opioïdes forts est passée de 18 à 421 mg/habitant/année. Cette augmentation pourrait être due à une meilleure prise en charge de la douleur, mais aussi à une prescription plus libérale d'opioïdes pour des indications non démontrées. Ainsi, davantage de recherche est nécessaire, et en parallèle une prudence accrue est recommandée aux praticiens lors de la prescription d'opioïdes.
