RESUMO
PURPOSE: This study aimed to identify opioid consumption trajectories among persons living with chronic pain (CP) and put them in relation to patient-reported outcomes 6 months after initiating multidisciplinary pain treatment. METHODS: This study used data from the Quebec Pain Registry (2008-2014) linked to longitudinal Quebec health insurance databases. We included adults diagnosed with CP and covered by the Quebec public prescription drug insurance plan. The daily cumulative opioid doses in the first 6 months after initiating multidisciplinary pain treatment were transformed into morphine milligram equivalents. An individual-centered approach involving principal factor and cluster analyses applied to longitudinal statistical indicators of opioid use was conducted to classify trajectories. Multivariate regression models were applied to evaluate the associations between trajectory group membership and outcomes at 6-month follow-up (pain intensity, pain interference, depression, and physical and mental health-related quality of life). RESULTS: We identified three trajectories of opioid consumption: "no or very low and stable" opioid consumption (n = 2067, 96.3%), "increasing" opioid consumption (n = 40, 1.9%), and "decreasing" opioid consumption (n = 39, 1.8%). Patients in the "no or very low and stable" trajectory were less likely to be current smokers, experience polypharmacy, use opioids or benzodiazepine preceding their first visit, or experience pain interference at treatment initiation. Patients in the "increasing" opioid consumption group had significantly greater depression scores at 6-month compared to patients in the "no or very low and stable" trajectory group. CONCLUSION: Opioid consumption trajectories do not seem to be important determinants of most PROs 6 months after initiating multidisciplinary pain treatment.

BACKGROUND: Evidence on sociodemographic determinants and spatial variations in the fruit and/or vegetable (FV) consumption was reported. This study aimed to explore geographical and sociodemographic disparities in the level of FV consumption among adults in Burkina Faso, using the national baseline data. METHODS: This was a cross-sectional secondary study of primary data obtained by the 2013 (September to October) World Health Organization Stepwise Approach to Surveillance survey conducted in Burkina Faso. The participants were 4402 women and men aged 25-64 years and living in all 13 Burkinabè Regions. Descriptive and analytical analyses were performed using Student's t test, ANOVA, the chi-square test, Fisher's exact test and logistic regressions. RESULTS: The prevalence of a typical daily consumption of at least three servings was 4.1% (95% CI: 3.6-4.8) for fruits and 6.6% (95% CI: 5.9-7.3) for vegetables. The national prevalence of adequate FV intake was 5.1% (95% CI: 4.4-5.8), and for two Regions ("Centre-Ouest" and "Nord") the pooled prevalence was 22.4%, while in the other eleven Regions its was significantly lower, 2.4% (p = 0.0001). Using quartiles derived from the national level of consumption, each of these two Regions had a higher proportion (about 50%) of their participants in the fourth quartile (the higher level). The associated sociodemographic factors with the adequate intake were being rural residents (aOR = 1.7, p = 0.011) and women (aOR = 1.3; p = 0.03). CONCLUSION: Except for the Regions of "Centre-Ouest" and "Nord" of Burkina Faso, the prevalence of adequate consumption of FV was very low in its other eleven Regions. Measures to increase consumption in urban people are urgent while women should be the key actor in the family-based approaches implementation and the nutrition education promoting FV consumption.

BACKGROUND: Nirmatrelvir/ritonavir has shown to reduce COVID-19 hospitalization and death before Omicron, but updated real-world evidence studies are needed. This study aimed to assess whether nirmatrelvir/ritonavir reduces the risk of COVID-19-associated hospitalization among high-risk outpatients. METHODS: A retrospective cohort study of outpatients with SARS-CoV-2 between March 15 and 15 October 2022, using data from the Quebec clinico-administrative databases. Outpatients treated with nirmatrelvir/ritonavir were compared with infected ones not receiving nirmatrelvir/ritonavir using propensity-score matching. Relative risk (RR) of COVID-19-associated hospitalization within 30 days was assessed using a Poisson regression. RESULTS: A total of 8402 treated outpatients were matched to controls. Regardless of vaccination status, nirmatrelvir/ritonavir treatment was associated with a 69% reduced RR of hospitalization (RR: .31; 95% CI: .28; .36; number needed to treat [NNT] = 13). The effect was more pronounced in outpatients with incomplete primary vaccination (RR: .04; 95% CI: .03; .06; NNT = 8), while no benefit was found in those with a complete primary vaccination (RR: .93; 95% CI: .78; 1.08). Subgroups analysis among high-risk outpatients with a complete primary vaccination showed that nirmatrelvir/ritonavir treatment was associated with a significant decrease in the RR of hospitalization in severely immunocompromised outpatients (RR: .66; 95% CI: .50; .89; NNT = 16) and in high-risk outpatients aged ≥70 years (RR: .50; 95% CI: .34; .74; NNT = 10) when the last dose of the vaccine was received at least 6 months ago. CONCLUSIONS: Nirmatrelvir/ritonavir reduces the risk of COVID-19-associated hospitalization among incompletely vaccinated high-risk outpatients and among some subgroups of completely vaccinated high-risk outpatients.

OBJECTIVE: This study aimed to evaluate the trends of the availability and readiness of the healthcare system to provide cardiometabolic (cardiovascular diseases (CVD) and diabetes) services in Burkina Faso in multiple political and insecurity crises context. DESIGN: We performed a secondary analysis of repeated nationwide cross-sectional studies in Burkina Faso. DATA SOURCE: Four national health facility survey data (using WHO Service Availability and Readiness Assessment (SARA) tool) conducted between 2012 and 2018 were used. PARTICIPANTS: In 2012, 686 health facilities were surveyed, 766 in 2014, 677 in 2016 and 794 in 2018. PRIMARY AND SECONDARY OUTCOME MEASURES: The main outcomes were the availability and readiness services indicators defined according to the SARA manual. RESULTS: Between 2012 and 2018, the availability of CVD and diabetes services significantly increased (67.3% to 92.7% for CVD and 42.5% to 54.0% for diabetes). However, the mean readiness index of the healthcare system to manage CVD decreased from 26.8% to 24.1% (p for trend <0.001). This trend was observed mainly at the primary healthcare level (from 26.0% to 21.6%, p<0.001). For diabetes, the readiness index increased (from 35.4% to 41.1%, p for trend=0.07) during 2012-2018. However, during the crisis period (2014-2018), both CVD (27.9% to 24.1%, p<0.001) and diabetes (45.8% to 41.1%, p<0.001) service readiness decreased. At the subnational level, the readiness index for CVD significantly decreased in all regions but predominantly in the Sahel region, which is the main insecure region (from 32.2% to 22.6%, p<0.001). CONCLUSION: In this first monitoring study, we found a low level and decreased trend of readiness of the healthcare system for delivering cardiometabolic care, particularly during the crisis period and in conflicted regions. Policymakers should pay more attention to the impact of crises on the healthcare system to mitigate the rising burden of cardiometabolic diseases.

(1) Background: Effective malaria case management relies on World Health Organization (WHO) recommended artemisinin-based combination therapies (ACTs), but partial resistance to artemisinin has emerged and is spreading, threatening malaria control and elimination efforts. The strategy of deploying multiple first-line therapies (MFT) may help mitigate this threat and extend the therapeutic life of current ACTs. (2) Methods: A district-wide pilot quasi-experimental study was conducted, deploying three different ACTs at the public health facility (PHF) level for uncomplicated malaria treatment from December 2019 to December 2020 in the health district (HD) of Kaya, Burkina Faso. Mixed methods, including household and health facility-based quantitative and qualitative surveys, were used to evaluate the pilot programme. (3) Results: A total of 2008 suspected malaria patients were surveyed at PHFs, of which 79.1% were tested by rapid diagnostic test (RDT) with 65.5% positivity rate. In total, 86.1% of the confirmed cases received the appropriate ACT according to the MFT strategy. The adherence level did not differ by study segment (p = 0.19). Overall, the compliance level of health workers (HWs) with MFT strategy was 72.7% (95% CI: 69.7-75.5). The odds of using PHF as the first source of care increased after the intervention (aOR = 1.6; 95% CI, 1.3-1.9), and the reported adherence to the 3-day treatment regimen was 82.1%; (95% CI: 79.6-84.3). Qualitative results showed a high acceptance of the MFT strategy with positive opinions from all stakeholders. (4) Conclusions: Implementing an MFT strategy is operationally feasible and acceptable by stakeholders in the health systems in Burkina Faso. This study provides evidence to support the simultaneous use of multiple first-line artemisinin combination therapies in malaria-endemic countries such as Burkina Faso.

RESUMO
A highly effective malaria vaccine remains elusive despite decades of research. Plasmodium falciparum sporozoite vaccine (PfSPZ Vaccine), a metabolically active, nonreplicating, whole parasite vaccine demonstrated safety and vaccine efficacy (VE) against endemic P. falciparum for 6 months in Malian adults receiving a five-dose regimen. Safety, immunogenicity, and VE of a three-dose regimen were assessed in adults in Balonghin, Burkina Faso in a two-component study: an open-label dose escalation trial with 32 participants followed by a double-blind, randomized, placebo-controlled trial (RCT) with 80 participants randomized to receive three doses of 2.7 × 106 PfSPZ (N = 39) or normal saline (N = 41) just before malaria season. To clear parasitemia, artesunate monotherapy was administered before first and last vaccinations. Thick blood smear microscopy was performed on samples collected during illness and every 4 weeks for 72 weeks after last vaccinations, including two 6-month malaria transmission seasons. Safety outcomes were assessed in all 80 participants who received at least one dose and VE for 79 participants who received three vaccinations. Myalgia was the only symptom that differed between groups. VE (1 - risk ratio; primary VE endpoint) was 38% at 6 months (P = 0.017) and 15% at 18 months (0.078). VE (1 - hazard ratio) was 48% and 46% at 6 and 18 months (P = 0.061 and 0.018). Two weeks after the last dose, antibodies to P. falciparum circumsporozoite protein and PfSPZ were higher in protected versus unprotected vaccinees. A three-dose regimen of PfSPZ Vaccine demonstrated safety and efficacy against malaria infection in malaria-experienced adults.

BACKGROUND: We compared the prevalence of unhealthy lifestyle factors between the hypertensive adults who were aware and unaware of their hypertensive status and assessed the factors associated with being aware of one's hypertension among adults in Burkina Faso. METHODS: We conducted a secondary analysis of data from the World Health Organization Stepwise approach to surveillance survey conducted in 2013 in Burkina Faso. Lifestyle factors analysed were fruits and vegetables (FV) consumption, tooth cleaning, alcohol and tobacco use, body mass index and physical activity. RESULTS: Among 774 adults living with hypertension, 84.9% (95% CI: 82.2-87.3) were unaware of their hypertensive status. The frequencies of unhealthy lifestyle practices in those aware vs. unaware were respectively: 92.3% vs. 96.3%, p = 0.07 for not eating, at least, five FV servings daily; 63.2% vs. 70.5%, p = 0.12 for not cleaning the teeth at least twice a day; 35.9% vs. 42.3%, p = 0.19 for tobacco and/or alcohol use; 53.9% vs. 25.4%, p = 0.0001 for overweight/obesity and 17.1% vs, 10.3%, p = 0.04 for physical inactivity. In logistic regression analysis, older age, primary or higher education, being overweight/obese [adjusted odds ratio (aOR) = 3.2; p < 0.0001], intake of adequate FV servings daily (aOR = 2.9; p = 0.023) and non-use of alcohol and tobacco (aOR = 0.6; p = 0.028) were associated with being aware of one's hypertensive status. CONCLUSION: Undiagnosed hypertension was very high among Burkinabè adults living with hypertension. Those aware of their hypertension diagnosis did not necessarily practise healthier lifestyles than those not previously aware of their hypertension. Current control programmes should aim to improve hypertension awareness and promote risk reduction behaviour.

BACKGROUND: In Burkina Faso, malaria remains the first cause of medical consultation and hospitalization in health centres. First-line case management of malaria in the country's health facilities is based on the use of artemisinin-based combination therapy (ACT). To optimize the use of these anti-malarial drugs in the perspective of mitigating the emergence of artemisinin resistance, which is a serious threat to malaria control and elimination, a pilot programme using multiple first-line therapies (MFTs) [three artemisinin-based combinations-pyronaridine-artesunate, dihydroartemisinin-piperaquine and artemether-lumefantrine] has been designed for implementation. As the success of this MFT pilot programme depends on the perceptions of key stakeholders in the health system and community members, the study aimed to assess their perceptions on the implementation of this strategy. METHODS: Semi-structured interviews, including 27 individual in-depth interviews and 41 focus groups discussions, were conducted with key stakeholders including malaria control policymakers and implementers, health system managers, health workers and community members. Volunteers from targets stakeholder groups were randomly selected. All interviews were recorded, transcribed and translated. Content analysis was performed using the qualitative software programme QDA Miner. RESULTS: The interviews revealed a positive perception of stakeholders on the implementation of the planned MFT programme. They saw the strategy as an opportunity to strengthen the supply of anti-malarial drugs and improve the management of fever and malaria. However, due to lack of experience with the products, health workers and care givers expressed some reservations about the effectiveness and side-effect profiles of the two anti-malarial drugs included as first-line therapy in the MFT programme (pyronaridine-artesunate, dihydroartemisinin-piperaquine). Questions were raised about the appropriateness of segmenting the population into three groups and assigning a specific drug to each group. CONCLUSION: The adherence of both populations and key stakeholders to the MFT implementation strategy will likely depend on the efficacy of the proposed drugs, the absence of, or low frequency of, side-effects, the cost of drugs and availability of the different combinations.

BACKGROUND: Malaria case management relies on World Health Organization (WHO)-recommended artemisinin-based combination therapy (ACT), and a continuous understanding of local community knowledge, attitudes, and practices may be a great support for the success of malaria disease control efforts. In this context, this study aimed to identify potential facilitators or barriers at the community level to inform a health district-wide implementation of multiple first-line therapies (MFT) as a new strategy for uncomplicated malaria case management. METHODS: A community-based cross-sectional study using a mixed-method design was carried out from November 2018 to February 2019, in the health district (HD) of Kaya in Burkina Faso. Quantitative data were collected using a standardized questionnaire from 1394 individuals who had fever/malaria episodes four weeks prior to the survey. In addition, 23 focus group discussions (FGDs) were conducted targeting various segments of the community. Logistic regression models were used to assess the predictors of community care-seeking behaviours. RESULTS: Overall, 98% (1366/1394) of study participants sought advice or treatment, and 66.5% did so within 24 h of fever onset. 76.4% of participants preferred to seek treatment from health centres as the first recourse to care, 5.8% were treated at home with remaining drug stock, and 2.3% preferred traditional healers. Artemether-lumefantrine (AL) was by far the most used anti-malarial drug (98.2%); reported adherence to the 3-day treatment regimen was 84.3%. Multivariate analysis identified less than 5 km distance travelled for care (AOR = 2.7; 95% CI 2.1-3.7) and education/schooling (AOR = 1.8; 95% CI 1.3-2.5) as determinants of prompt care-seeking for fever. Geographical proximity (AOR = 1.5, 95% CI 1.2-2.1), having a child under five (AOR = 4.6, 95% CI 3.2-6.7), being pregnant (AOR = 6.5, 95% CI 1.9-22.5), and living in an urban area (AOR = 2.8, 95% CI 1.8-4.2) were significant predictors for visiting health centres. The FGDs showed that participants had good knowledge about malaria symptoms, prevention tools, and effective treatment. Behaviour change regarding malaria treatment and free medication for children under five were the main reasons for participants to seek care at health centres. CONCLUSIONS: The study showed appropriate knowledge about malaria and positive community care-seeking behaviour at health centres for fever/malaria episodes. This could potentially facilitate the implementation of a MFT pilot programme in the district. CLINICALTRIALS: gov Identifier: NCT04265573.

BACKGROUND: Sociodemographic parameters are the driving determinants of oral hygiene practices. This study aims to describe oral hygiene practices and associated sociodemographic factors in the Burkinabè population using the first nationally representative data. METHODS: This descriptive, cross-sectional study included 4677 adults through multistage cluster sampling performed during the first WHO STEPS survey conducted in 2013 in Burkina Faso. The practices we considered were the frequencies of tooth cleaning, fluoridated toothpaste use and dentist visits within the last six months. Sociodemographic variables and oral hygiene practices were described, and the first variables were used as the explanatory variables for the seconds in the multivariable analyses. RESULTS: Individuals who cleaned teeth at least once a day represented 82.8% and at least twice a day represented 31.4%; 25.6% used fluoridated toothpaste and 2.1% visited a dentist. With the highest odds ratio, only being educated was a favourable factor for each oral hygiene practice. Living in an urban area or being a younger adult were favourable factors for cleaning teeth at least twice a day or the use of a fluoridated paste. Female gender applied more to regular tooth cleaning, as well as to dentist visits. CONCLUSION: Cleaning teeth at least once a day was common among Burkinabè, while cleaning at least twice a day, the use of fluoridated paste or dentist visits were infrequent. Education was the key favourable determinant for healthy oral hygiene practices, and improving oral health literacy interventions through basic health education should be promoted.

INTRODUCTION: studies on stroke recurrence are rare in sub-Sahara Africa. The aim to this study is to determine the prevalence and risk factors for recurrent stroke in two University Teaching Hospital in Burkina Faso. METHODS: this prospective cross-sectional study was carried on 266 stroke patients admitted in two hospitals in the city of Ouagadougou from September 1, 2017 to February 28, 2018. Patients with stroke recurrence (ischemic or hemorrhagic) were included. RESULTS: of 266 acute stroke patients included, 44 (16.4%) had recurrent stroke. The mean age of patients was 66.5 ± 11.49 years with male predominance. Hypertension was the most vascular risk factors (81.8%). Previous stroke was ischemic in 61.4%, hemorrhagic in 22.7% and unknown in 15.9% of cases. Poor compliance (< 60%) was determined in patients taking antiagregant (43.6%) and statins (50%). At admission, the most neurological disorders was motor deficit (100%), aphasia (84.1%), and deglutition disorders (15.9%). CT scan showed ischemic in 82% and hemorrhagic stroke in 18% of cases. With the analysis of second stroke, recurrent stroke after intracerebral hemorrhage was hemorrhagic in 77.8% and ischemic in 22.2%. Recurrent stroke after ischemic stroke was ischemic in 100%. CONCLUSION: stroke recurrence is common in our context. Hypertension was the most common vascular risk factor in recurrent stroke. Poor compliance was determined in patients taking antiagregant agents and statins in previous stroke.

BACKGROUND: Snake bites remain a major medical problem in West Africa, and hemorrhagic stroke following a snakebite has emerged as a rare secondary condition. The objective of this study was to determine the neurological complications following snake bite. METHODS: This study included all the cases of hemorrhagic stroke following snake bite admitted in the neurology Department of Yalgado Ouedraogo University Teaching Hospital during the period from January 1st, 2018 to December 31st 2019. RESULTS: Three cases of hemorrhagic stroke following snake bite were included in the study. The strokes occurred 4-15 days after the snakebite. Traditional treatment was applied in two cases. Complications were significant, including local manifestations and severe anemia in 2 patients who received blood transfusion. Snake anti-venom was applied. At admission, motor deficit, conscience disorders and fever were the most frequent complaints. Patients received repeated dose of snake anti-venom was applied, antitetanus prophylaxis and antibiotherapy during hospitalization. The majority of the patients had completely recovered. CONCLUSIONS: Hemorrhagic stroke following snake bites are rare in Burkina Faso. Clinical outcome of stroke was favorable after treatment by antivenom, anti-tetanus serum and antibiotics.
RESUMO
A recent randomized controlled trial, the WANECAM (West African Network for Clinical Trials of Antimalarial Drugs) trial, conducted at seven centers in West Africa, found that artemether-lumefantrine, artesunate-amodiaquine, pyronaridine-artesunate, and dihydroartemisinin-piperaquine all displayed good efficacy. However, artemether-lumefantrine was associated with a shorter interval between clinical episodes than the other regimens. In a further comparison of these therapies, we identified cases of persisting submicroscopic parasitemia by quantitative PCR (qPCR) at 72 h posttreatment among WANECAM participants from 5 sites in Mali and Burkina Faso, and we compared treatment outcomes for this group to those with complete parasite clearance by 72 h. Among 552 evaluable patients, 17.7% had qPCR-detectable parasitemia at 72 h during their first treatment episode. This proportion varied among sites, reflecting differences in malaria transmission intensity, but did not differ among pooled drug treatment groups. However, patients who received artemether-lumefantrine and were qPCR positive at 72 h were significantly more likely to have microscopically detectable recurrent Plasmodium falciparum parasitemia by day 42 than those receiving other regimens and experienced, on average, a shorter interval before the next clinical episode. Haplotypes of pfcrt and pfmdr1 were also evaluated in persisting parasites. These data identify a possible threat to the parasitological efficacy of artemether-lumefantrine in West Africa, over a decade since it was first introduced on a large scale.

BACKGROUND: Opioid doctor shopping has not yet been investigated in patients followed in tertiary care settings. This study aimed at assessing the prevalence of opioid doctor shopping among patients with chronic non-cancer pain (CNCP) (ie, pain lasting ≥3 months) attending multidisciplinary pain clinics in Quebec, Canada. PATIENTS AND METHODS: This was a retrospective cohort study of patients with CNCP enrolled in the Quebec Pain Registry (QPR) between 2008 and 2014. QPR data were linked to the Quebec health insurance databases. The index date was the date of the first visit at the pain clinic. Prevalence of doctor shopping was assessed within the 12 months following the index date. Doctor shopping was defined as at least 1 day of overlapping opioid prescriptions from ≥2 prescribers and filled in ≥3 pharmacies. RESULTS: A total of 2191 patients with CNCP with at least one opioid dispensation within the 12 months following the index date were included. The mean age was 58.6±14.9 years and 41.3% were men. The median pain duration was 4 years, and 13.3% of patients were diagnosed with neuropathic pain. Regarding past year comorbidities, 15.0% presented anxiety, 16.8% depression and 6.4% substance use disorder. Among the included patients, 15 (0.7%) presented at least one episode of doctor shopping. Among these doctor-shoppers, 9 (60.0%) exhibited only 1 episode. CONCLUSION: Opioid doctor shopping is a rare phenomenon among patients with CNCP treated in tertiary care settings. Opioids should remain a drug option for patients without substance use disorder, and who have persistent pain despite optimized nonopioid therapy.
RESUMO
Background: The opioid overdose epidemic has led health care providers to increased vigilance for opioid-related risks in the treatment of chronic non-cancer pain (CNCP). Media have conveyed stigmatizing representations of opioid analgesics. Aims: This study aimed to understand how the opioid overdose epidemic has impacted health care experiences among people living with CNCP in two Canadian provinces (British Columbia, Quebec). Methods: This qualitative study proceeded through 22 semi-structured interviews conducted in 2019. Participants were recruited from a cross-sectional survey examining the effects of the opioid overdose epidemic on individuals with CNCP. We collected in-depth narratives that we analyzed using a thematic framework. The sample included 12 women and 10 men aged 20 to 70 years, with 11 from each province. Results: Several participants described increased difficulty in accessing medical services for pain since the onset of the opioid overdose epidemic. They reported that some physicians urged them to taper opioids regardless of their pain severity and functional limitations. Some participants reported facing discrimination and care denials as they were labeled "drug-seeking," especially in hospital. Depending on their educational resources, they were unequally able to counter providers' stigmatizing behaviors. However, participants described empathetic relationships with providers with whom they had a long-term relationship. Some participants drew distinctions between themselves and the stigmatized status of "addict" in ways that reinforced stigma toward people who are dependent on opioids. Conclusions: Health policies and provider education programs aimed at reducing opioid-related stigma are needed to counter detrimental consequences of the opioid overdose epidemic for people living with CNCP.
Contexte: L'épidémie de surdose d'opioïdes a conduit les prestataires de soins de santé à une vigilance accrue des risques liés aux opioïdes dans le traitement de la douleur chronique non cancéreuse (DCNC). Les médias ont véhiculé des représentations stigmatisantes des analgésiques opioïdes.Objectifs: Cette étude visait à comprendre comment l'épidémie de surdose d'opioïdes a eu un impact sur les expériences avec les soins de santé des personnes vivant avec la DCNC dans deux provinces canadiennes (Colombie-Britannique, Québec).Méthodes: Cette étude qualitative a été réalisée au moyen de 22 entretiens semi-structurés menés en 2019. Les participants ont été recrutés à partir d'une enquête transversale examinant les effets de l'épidémie de surdose d'opioïdes sur les personnes atteintes de DCNC. Nous avons recueilli des récits approfondis que nous avons analysés en utilisant un cadre thématique. L'échantillon comprenait 12 femmes et 10 hommes âgés de 20 à 70 ans, parmi lesquels 11 provenaient de chacune des deux provinces.Résultats: Plusieurs participants ont décrit une difficulté accrue à avoir accès aux services médicaux pour la douleur depuis le début de l'épidémie de surdose d'opioïdes. Ils ont déclaré que certains médecins les avaient incités à réduire les opioïdes, quelle que soit la gravité de leur douleur et leurs limitations fonctionnelles. Certains participants ont déclaré être confrontés à de la discrimination et au refus de soins car ils ont été qualifiés de « chercheurs de drogue ¼, en particulier à l'hôpital. En fonction de leurs ressources éducatives, ils ont été inégalement capables de contrer les comportements stigmatisants des prestataires. Cependant, les participants ont décrit des relations d'empathie avec les prestataires avec lesquels ils avaient une relation à long terme. Certains participants ont établi des distinctions entre eux-mêmes et le statut stigmatisé de « toxicomane ¼ d'une manière qui renforce la stigmatisation des personnes dépendantes aux opioïdes.Conclusions: Les politiques de santé et les programmes d'éducation des prestataires visant à réduire la dépendance aux opioïdes et la stigmatisation liée aux opioïdes est nécessaire afin de contrer les conséquences néfastes de l'épidémie de surdose d'opioïdes pour les personnes vivant avec la DCNC.
RESUMO
Chronic pain and substance use disorders frequently co-occur. Indeed, chronic pain is highly prevalent, affecting 23-68% of patients receiving opioid agonist treatments (OAT) worldwide. The majority of available estimates come from American studies, but data are still lacking in Europe. We aim to provide European estimates of the prevalence of chronic pain in patients receiving OAT using French data, since France is the first European country in terms of number of patients with OAT. The secondary objectives were to characterize the features and management of chronic pain, as well identify associated risk factors. We conducted a multicenter, cross-sectional study, recruiting patients treated either with buprenorphine or methadone in 19 French addiction centers, from May to July 2016. All participants had to complete a semi-directed questionnaire that collected sociodemographic and medical data, pain characteristics, and licit or illicit drug consumption. In total, 509 patients were included. The prevalence of chronic pain was estimated at 33.2% (95% CI: 29.1-37.3). Compared to non-chronic pain patients, chronic pain patients were older (38.4 vs. 36.1 years, p = 0.006), were more unemployed (66 vs. 52%, p = 0.003), had more psychiatric comorbidities (50 vs. 39%, p = 0.02), and split their OAT for pain management more frequently (24 vs. 7%, p = 0.009). Pain intensity was moderate or severe in 75% of chronic pain patients. Among patients with chronic pain, 15.4% were not prescribed, and did not self-medicate with, any analgesic drugs, 52.1% were prescribed analgesics (non-opioid analgesics, 76.3%; codeine, tramadol, opium, 27.2%; and morphine, fentanyl, oxycodone, 11.8%), and 32.5% exclusively self-medicated with analgesics. Moreover, 20.1% of patients with chronic pain also used illicit drugs for pain relief. On multivariate analysis, variables that remained significantly associated with chronic pain were age [OR = 1.03 (95% CI: 1.00-1.05], p = 0.02], anxiety [OR = 1.52 (1.15-2.02), p = 0.003], and depression [OR = 1.25 (1.00-1.55), p = 0.05]. Chronic pain is a highly prevalent condition in patients receiving OAT, and its appropriate management remains uncertain, since insufficient relief and frequent additional self-medications with analgesics or illicit drugs were reported by these patients. Increased awareness among caregivers is urgently needed regarding a systematic and careful assessment, along with an adequate management of chronic pain in patients receiving OAT.
RESUMO
OBJECTIVES: Little is known about the consequences of the opioid epidemic on people living with chronic noncancer pain (CNCP). This study examined this issue in people who lived in the most impacted province by opioid overdoses in Canada (British Columbia [BC]) or one of the least impacted (Quebec [QC]), and examined the factors associated with opioid use. MATERIALS AND METHODS: This cross-sectional study was carried out in adults living in BC (N=304) and QC (N=1071) who reported CNCP (≥3 months) and completed an online questionnaire that was tailored to their opioid status. RESULTS: Almost twice as many participants in BC as in QC were proposed to cease their opioid medication in the past year (P<0.001). The proportion who reported having hoarded opioids in fear of not being able to get more in the future was also significantly higher in BC (P<0.001) compared with QC. In addition, they were significantly more likely to have had their opioid dose decreased than those in QC (P=0.001). No significant association was found between opioid discontinuation and province of residence. Two-thirds of the BC participants felt that the media coverage of the opioid crisis was very to extremely detrimental to CNCP patients in general, this percentage being significantly higher than in QC (P<0.001). DISCUSSION: The opioid epidemic and associated prescribing restrictions have had harmful effects on Canadians with CNCP. The clinical community, the general public, and the media need to be aware of these negative consequences to decrease patients' stigmatization and minimize inadequate treatment of CNCP.

The objective of this study was to understand the impact of the opioid overdose epidemic on the social lives of people suffering from chronic pain, focusing on interactions within their personal and professional circles. The study was based on 22 in-depth interviews with people living with chronic pain in Canada. Using thematic analysis, we documented three main impacts of the opioid overdose epidemic: (a) increased worries of people in pain and their families regarding the dangers of opioids; (b) prejudices, stigma, and discrimination faced during conversations about opioids; and (c) stigma management attempts, which include self-advocacy and concealment of opioid use. This study represents important knowledge advancement on how people manage stigma and communicate about chronic disease during everyday life interactions. By showing negative effects of the epidemic's media coverage on the social experiences of people with chronic pain, we underscore needs for destigmatizing approaches in public communication regarding opioids.
