A Machine Learning Sepsis Prediction Algorithm for Intended Intensive Care Unit Use (NAVOY Sepsis): Proof-of-Concept Study
Authors: Persson Inger , Östling Andreas , Arlbrandt Martin , Söderberg Joakim , Becedas David
Published: August 2021

Background

Despite decades of research, sepsis remains a leading cause of mortality and morbidity in intensive care units worldwide. The key to effective management and patient outcome is early detection, for which no prospectively validated machine learning prediction algorithm is currently available for clinical use in Europe.

Objective

We aimed to develop a high-performance machine learning sepsis prediction algorithm based on routinely collected intensive care unit data, designed to be implemented in European intensive care units.

Methods

The machine learning algorithm was developed using convolutional neural networks, based on Massachusetts Institute of Technology Lab for Computational Physiology MIMIC-III clinical data from intensive care unit patients aged 18 years or older. The model uses 20 variables to produce hourly predictions of onset of sepsis, defined by international Sepsis-3 criteria. Predictive performance was externally validated using hold-out test data.

Results

The algorithm—NAVOY Sepsis—uses 4 hours of input and can identify patients with high risk of developing sepsis, with high performance (area under the receiver operating characteristics curve 0.90; area under the precision-recall curve 0.62) for predictions up to 3 hours before sepsis onset.

Conclusions

The prediction performance of NAVOY Sepsis was superior to that of existing sepsis early warning scoring systems and comparable with those of other prediction algorithms designed to predict sepsis onset. The algorithm has excellent predictive properties and uses variables that are routinely collected in intensive care units.
Self-Reported Preferences for Help-Seeking and Barriers to Using Mental Health Supports Among Internal Medicine Residents: Exploratory Use of an Econometric Best-Worst Scaling Framework for Gathering Physician Wellness Preferences
Authors: Wu Andrew , Radhakrishnan Varsha , Targan Elizabeth , Scarella Timothy M , Torous John , Hill Kevin P
Published: August 2021

Background

Burnout interventions are limited by low use. Understanding resident physician preferences for burnout interventions may increase utilization and improve the assessment of these interventions.

Objective

This study aims to use an econometric best-worst scaling (BWS) framework to survey internal medicine resident physicians to establish help-seeking preferences for burnout and barriers to using wellness supports by quantifying selections for 7 wellness support options and 7 barriers.

Methods

Internal medicine resident physicians at our institution completed an anonymous web-based BWS survey during the 2020-2021 academic year. This cross-sectional study was analyzed with multinomial logistic regression and latent class modeling to determine the relative rank ordering of factors for seeking support for burnout and barriers to using wellness supports. Analysis of variance with Tukey honest significant difference posthoc test was used to analyze differences in mean utility scores representing choice for barriers and support options.

Results

Of the 163 invited residents, 77 (47.2% response rate) completed the survey. Top-ranking factors for seeking wellness supports included seeking informal peer support (best: 71%; worst: 0.6%) and support from friends and family (best: 70%; worst: 1.6%). Top-ranking barriers to seeking counseling included time (best: 75%; worst: 5%) and money (best: 35%; worst: 21%).

Conclusions

Overall, our findings suggest that low utilization of formal mental health support is reflective of resident preferences to seek help informally and that increasing utilization will require addressing pragmatic barriers of time and cost. Assessing physician preferences for wellness-related initiatives may contribute to understanding the low utilization of formal mental health services among physicians, which can be determined using a BWS framework.
Assessing the Care Modality Preferences and Predictors for Digital Mental Health Treatment Seekers in a Technology-Enabled Stepped Care Delivery System: Cross-sectional Study
Authors: Kozlov Elissa , McDarby Meghan , Prescott Maximo , Altman Myra
Published: August 2021

Background

Access to mental health services continues to be a systemic problem in the United States and around the world owing to a variety of barriers including the limited availability of skilled providers and lack of mental health literacy among patients. Individuals seeking mental health treatment may not be aware of the multiple modalities of digital mental health care available to address their problems (eg, self-guided and group modalities, or one-to-one care with a provider). In fact, one-to-one, in-person treatment is the dominant care model with a masters- or doctoral-level trained mental health provider, and it may or may not be the appropriate or preferred level of care for an individual. Technology-enabled mental health platforms may be one way to improve access to mental health care by offering stepped care, but more research is needed to understand the care modality preferences of digital mental health care seekers because additional modalities become increasingly validated as effective treatment options.

Objective

The purpose of this study was to describe and evaluate the predictors of care modality preferences among individuals enrolled in a technology-enabled stepped mental health care platform.

Methods

This exploratory, cross-sectional study used employee data from the 2021 Modern Health database, an employer-sponsored mental health benefit that uses a technology-enabled platform to optimize digital mental health care delivery. Chi-square tests and one-way analysis of variance (ANOVA) were conducted to evaluate associations among the categorical and continuous factors of interest and the preferred care modality. Bivariate logistic regression models were constructed to estimate the odds ratios (ORs) of preferring a one-on-one versus self-guided group, or no preference for digital mental health care modalities.

Results

Data were analyzed for 3661 employees. The most common modality preference was one-on-one care (1613/3661, 44.06%). Approximately one-fourth of the digital mental health care seekers (881/3661, 24.06%) expressed a preference for pursuing self-guided care, and others (294/3661, 8.03%) expressed a preference for group care. The ORs indicated that individuals aged 45 years and above were significantly more likely to express a preference for self-guided care compared to individuals aged between 18 and 24 years (OR 2.47, 95% CI 1.70-3.59; P<.001). Individuals screening positive for anxiety (OR 0.73, 95% CI 0.62-0.86; P<.001) or depression (OR 0.79, 95% CI 0.66-0.95; P=.02) were more likely to prefer one-on-one care.

Conclusions

Our findings elucidated that care modality preferences vary and are related to clinical severity factors and demographic variables among individuals seeking digital mental health care.

Light is an important factor for the growth of many forms of life, including mushrooms. This paper highlights the effects of the different wavelengths (red, 650 nm; blue, 450 nm; green, 525 nm) of light emitting diodes (LEDs) on the growth, biomass production and antioxidant properties of Ganoderma lucidum. G. lucidum is a white-rot, wood-degrading fungus in the Basiodiomycota that typically grows on logs. Mycelia were grown on coconut water agar (CWA) solid media for analysis of mycelial colony diameter as well as coconut water (CW) submerged culture for analysis of mycelial biomass weight. Both set-ups were incubated in variously-colored LED chambers. The DPPH radical scavenging activity and total phenolic content of the harvested mycelia were also determined. After three days of incubation, G. lucidum mycelia under red LED recorded the highest mean mycelial colony diameter of 72.50 mm. In terms of mycelia biomass production, G. lucidum mycelia exposed in red LED and dark produced the heaviest weight. On the other hand, mycelia grown under green LED had the highest radical scavenging activity of 66.49% while those harvested from red LED showed the highest total phenolic content of 81.29 mg GAE / g of sample. Our results demonstrate that LED color influences the mycelial growth, biomass production and antioxidant activities of G. lucidum.

The gross morphology of the heart of mature Philippine water buffalo was described by determining the weight, length, width and circumference; measured the average external circumference of the pulmonary veins and artery, cranial and caudal vena cava and the aorta; determined the presence and location of ligamentum arteriosum; measured the thickness of the atrial and ventricular wall; described the components of the left and right atrioventricular valves, pulmonary valves and the aortic valves; determined the location and measured the length of trabeculae septomarginalis and determined the location of the os cordis. Hearts of ten mature Philippine water buffalo of both sexes were collected from abattoirs of Cabanatuan City. The absolute and relative weights of the heart were measured using digital weighing scale. Different dimensions like circumferences, length, and width of the heart; the external circumferences of major blood vessels; and the thickness of the wall of heart were determined using measuring tape and Vernier caliper. The number of cusps present in the left and right atrioventricular, pulmonary, and aortic valves was counted and the presence of ligamentum arteriosum was documented. Radiograph was used to determine the presence and location of os cordis. All of the hearts studied were pointed and bilaterally flattened. The base of the heart is markedly surrounded with fatty tissues. The mean absolute weight is 2.42 kg. The heart has a mean dimension of 21.71 cm x 17.49 cm. The mean circumference at the level of the coronary groove, middle and apex were 48.41 cm, 44.10 cm and 20.57 cm, respectively. An average of four pulmonary veins was documented to be present. The right ventricle has a constant three papillary muscles and three cusps while the left ventricle has a constant two papillary muscles and two cusps. The number of cusps of both pulmonary valve and aortic valve was three. Ligamentum arteriosum was present in all samples and it is located between the pulmonary trunk and aorta. The os cordis which is located at the aortic fibrous ring is present in all heart of Philippine water buffalo examined.

Published: August 2021

The study aimed to determine the effect of Arabica coffee- Benguet pine based agroforestry system on soil-litter collembolan diversity. Under this agroforestry system, two coffee production systems were identified in this study, the Agroforestry Coffee System (ACS) and Lone Coffee System (LCS). ACS have coffee plants growing under Benguet pine trees while LCS have coffee plants that are not under any shade trees. Shannon diversity index (H’), Margalef’s richness index (Dmg), Soil temperature (ST), and Soil Moisture Content (SMC) data were gathered and subjected to linear regression with correlation analysis, and student T-test. The result of this study revealed a higher species richness of collembola under ACS (Dmg =3.52±0.47) than LCS (Dmg = 1.75±0.36). Similarly, ACS has higher diversity index (H’ = 1.68±0.66) than LCS (H’ = 0.90±0.49). ACS ST and SMC was 18.60±0.21℃ and 68.34±12.22% while LCS was 21.24±1.31℃ and 55.38±5.52%. ST had significant negative association with diversity and SMC had positive association with diversity. However, only Dmg had significant correlation with SMC. In regression analysis, 18.7% of the total variation in H’ was explained by ST. While for Dmg, 56.6% and 21.7% of its total variations were explained by ST and SMC, respectively. These results showed that ACS can conserve collembolan diversity because it creates a microclimatic condition favorable for the collembolans. This finding could serve as basis for endeavors to promote and develop agroforestry systems.

The amount of gelatin used worldwide in the food industry is increasing annually. Recovery of valuable components from fish processing-by products could help solve problems on tons of wastes produced each year and address religious beliefs like Islam and Judaism as well as the fear of mad cow disease. In this study, gelatin was extracted from milkfish scales for food application. The physical properties (yield, strength, color, clarity and pH) of extracted gelatin were studied and compared with commercially-available bovine gelatin. Marshmallows were developed from these gelatin sources. Sensory evaluation was done to determine the appropriateness of the level of a specific attribute and the consumer’s preference using the nine-point hedonic and just about right (JAR) scales. The extracted fish gelatin was comparable to bovine gelatin in terms of strength but they differ in terms of color, clarity and pH. The fish gelatin had a yield of 8.7%, high bloom value of 505g, white appearance and an acidic pH (5.25). The marshmallow developed from fish gelatin is comparable to bovine gelatin in all attributes (color, aroma, texture, taste, sweetness and aftertaste) except for sweetness. Overall, the gelatin extracted from milkfish scales can be used as an alternative to bovine gelatin for food application such as in marshmallow production.

#DevResearch: Exploring Development Researchers Twitter Use for Research Dissemination
Authors: Khandelwal Anchal , Tagat Anirudh
Published: August 2021

Social media is increasingly used by researchers to discuss research and policy.However, little is known about access to social media as well as the nature of its use among development studies researchers. This study combines survey data on the social media use of 131 development researchers with data on 56,512 tweets by development researchers. Development researchers are most active on Twitter and Facebook, and use them to engage with academics and students. Twitter data reveal that only a small fraction of tweets explicitly discuss their country of residence. Implications for understanding the role of social media in the dissemination and use of development research are provided.
Les chercheurs ont de plus en plus recours aux médias sociaux pour discuter de recherche et de politiques. Cependant, on en sait peu sur l’accès aux médias sociaux par les chercheurs en études du développement et leur utilisation de ceux-ci. Cet article combine les données provenant d’un sondage fait auprès de 131 chercheurs en développement et les données sur 56,512 Tweets envoyés par des chercheurs en développement. Ces chercheurs sont particulièrement actifs sur Twitter et Facebook, utilisant ces réseaux pour échanger avec des académiques et des étudiants. Cependant,les données sur Twitter révèlent qu’une part infime seulement des Tweets discutent explicitement de leur pays de résidence. Cette étude traite ainsi d’approches pour comprendre le rôle des médias sociaux dans la dissémination et l’utilisation de la recherche en développement.
Discrete Lyapunov function by means of a discrete residual energy function and stability analysis for discrete time physical systems
Authors: Civelek Cem
Published: August 2021

In this research paper beginning from the fundamental concepts, all the
basic approach is introduced for short. Then after obtaining the
discrete Lagrange-dissipative model ({L,D}- model for short) of a
discrete time observed physical/engineering dynamic system, the model
will be used to develope the discrete Hamiltonian together with discrete
dissipation energy as discrete Lyapunov function and as such, a
systematic method is proposed to obtain discrete Lyapunov function in
form of a residual energy function for discrete (time) observed physical
systems to analyze the discrete time system related to stability.
Stability analysis of a discrete time observed physical dynamic system
is performed using discrete Lyapunov function in form of a residual
energy function consisting of Hamiltonian together with dissipation
energy. Application of the method was shown using two discrete time
physical examples, one of which is a coupled one and time dependent.
This coupled physical discrete time example is analyzed related to
stability using two different formulations, one form of which leads to a
result.
Utilization and Outcomes of Postcardiotomy Mechanical Circulatory Support
Authors: Hess Nicholas , Wang Yisi , Kilic Arman
Published: August 2021

Background: This study evaluated the utilization and outcomes of
postcardiotomy mechanical circulatory support (MCS). Methods: This was a
retrospective, single institution analysis of adult cardiac surgery
cases that required de novo MCS following surgery from 2011-2018.
Patients that were bridged with MCS to surgery were excluded. The
primary outcomes were early operative mortality and longitudinal
survival. Secondary outcomes included postoperative complications, and
five-year all-cause readmission. Results: 533 patients required de novo
postcardiotomy MCS, with the most commonly performed procedure being
isolated coronary artery bypass grafting (29.8%). Median
cardiopulmonary bypass and cross clamp times were 185 (IQR 123-260)
minutes and 122 (IQR 81-179) minutes, respectively. A total of 442
(82.9%) of patients were supported with intra-aortic balloon pump
counterpulsation, 23 (4.3%) with an Impella device, and 115 (21.6%)
with extracorporeal membrane oxygenation. Three (0.6%) patients had an
unplanned ventricular assist device placed. Operative mortality was
29.8%. Longitudinal survival was 56.1% and 43.0% at 1- and 5-years,
respectively. Survival was lowest in those supported with ECMO and
highest with those supported with an Impella (P<0.001).
Freedom from readmission was 61.4% at 5-years. Postoperative ECMO was
an independent predictor of mortality (HR 5.1, 95% CI 2.0-12.9,
P<0.001), but none of the MCS types predicted long-term
hospital readmission after risk adjustment. Conclusions: Postcardiotomy
MCS is associated with high operative mortality. Even patients that
survive to discharge have compromised longitudinal survival, with nearly
only half surviving to 1-year. Close follow-up and early referral to
advanced heart failure specialists may be prudent in improving these
outcomes.
The Improvement of Discrete Wavelet Transform
Authors: Zhang Zhihua
Published: August 2021

Discrete wavelet transform and discrete periodic wavelet transform have
been widely used in image compression and data approximation. Due to
discontinuity on the boundary of original data, the decay rate of the
obtained wavelet coefficients is slow. In this study, we use the
combination of polynomial interpolation and
one-dimensional/two-dimensional discrete periodic wavelet transforms to
mitigate boundary effects. The decay rate of the obtained wavelet
coefficients in our improved algorithm is faster than that of
traditional two-dimensional discrete wavelet transform. Moreover, our
improved algorithm can be extended naturally to the higher-dimensional
case.

Authors: Jiang Xuan , Shi Enyi , Fan Ruixin , Qian Ximing , Zhang Hongjia , Gu Tianxiang
Published: August 2021

Background: Acute type A aortic dissection(ATAAD) is life-threatening
and requires immediate surgery. Sudden chest pain may lead to a risk of
misdiagnosis as acute coronary syndrome and may lead to subsequent
antiplatelet therapy. We used the Chinese Acute Aortic Syndrome
Collaboration Database (AAS) to study the effects of antiplatelet
therapy (APT) on clinical outcomes. Methods: The AAS database is a
retrospective multicentre database where 31 of 3092 had APT with aspirin
or clopidogrel or both before surgery. Before and after propensity score
matching, the incidence of complications and mortality was compared
between APT and non-APT patients by using a logistic regression model.
The sample remaining after PSM was 30 in the APT group and 80 in the
non-APT group. Results: The sample remaining after matching was 30 in
the APT group and 80 in the non-APT group. We found 10 cases with
percutaneous coronary intervention in the APT group(33.3%). The APT
group received more volume of packed red blood cell (RBC), 8.4±6.05
units; plasma, 401.67±727 ml, and platelet transfusion(14.07±8.92
units). The drainage volume was much more in the APT group(
5009.37±2131.44ml, P=0.004). Mortality was higher in APT group(26% vs
10%, P=0.027). The preoperative APT was independent predictor of
mortality(OR 6.808, 95% CI1.554-29.828, P = 0.011). Conclusion: APT
prior to ATAAD repair was associated with more transfusions and higher
early mortality. The timing of surgery should be carefully considered
based on the patient’s status and the surgeon’s experience.
Fast and efficient CO2 absorption in non-aqueous tertiary amines promoted by ethylene glycol

Published: August 2021

With the catalytic induction of EG, anhydrous DMEA shows
CO absorption performance via chemical binding and
physical storage under normal pressure. Among the absorbents, pure DMEA
can hardly absorb CO directly but when the zwitterionic
alkylcarbonates are formed between CO and DMEA-EG which
can be characterized by C NMR and FTIR, the
absorption rate of CO will be improved at this time. An
increasing the CO loading as the mass fraction of EG in
DMEA-EG, 90wt.% EG captures up to 0.72 mol/mol. The amount of
chemically bound and physically stored is directly dependent on
temperature, within the range of 293 to 323K, an absorption-regeneration
cycle can be formed in a closed vessel because of the zwitterion
DMEA-EG-CO is unstable at the higher temperature. In
other words, DMEA-EG-CO can be easily regenerated upon
appropriate depressurization or heating, corresponding thermodynamic
calculations prove that the regenerative energy of
DMEA-EG-CO is 25.49kJ/mol.

Published: August 2021

Poly(vinyl butyral) is selected as a promising ethanol-permselective
membrane based the solubility parameter theory, however it exhibits
anomalous water perm-selectivity in practical pervaporation process.
Comprehensive analysis based on experimental and theoretical methods
were carried out to explore the inherent mechanism of the anomalous
performance. Firstly, sum frequency generation vibrational spectra and
contact angle were developed to quantify the surface reconstruction of
membrane in air and ethanol, which indicated that hydrophilic hydroxyl
tended to expose on membrane surface with ethanol thus improved the
membrane affinity to water. Meanwhile, swelling behaviors proved more
water would accumulate in the ethanol swollen membrane. Furthermore,
theoretical analysis in terms of sorption and diffusion process, based
on the UNIFAC-FV model and Fujita free volume theory, confirmed the
mechanism of anomalous phenomenon of poly(vinyl butyral) membrane. The
comprehensive investigation was expected to provide insights into the
basic separation mechanism of pervaporation process.

DESIGNING FOR DIVERSITY: INCLUSIVE SAMPLING
Authors: Roscoe Rod D.
Published: August 2021

Experts in human factors and ergonomics (HF/E) and related fields have the ability and responsibility to broadly serve  the needs and goals of diverse people, which encompasses issues of inclusion, equity, and justice. Importantly, HF/E designers, researchers, and practitioners can address these aims both as the intended outcomes of their work and how the work itself is conducted. Both pathways support progress toward more inclusive and equitable organizations and societies. This paper focuses upon one aspect of inclusive methodology—strategies for inclusive sampling. Sampling is an important focus because of its fundamental role in defining the internal and external validity of findings. Moreover, sampling is how diverse participants and perspectives are incorporated (or not), and thus represents an early way that exclusion, inequity, or inaccessibility may manifest. Three heuristic questions and six sets of strategies are briefly articulated: (1) purposive sampling, (2) oversampling, (3) community sampling, (4) removing barriers of distance, cost, communication, and awareness, (5) building trust, and (6) inclusive demographic categories. A variety of sources are cited to facilitate readers’ further consideration of these issues in their own HF/E endeavors.

O design das embalagens dos produtos depende do conhecimento de diferentes áreas, incluindo aquelas voltadas para a qualidade mecânica, como em Engenharia Mecânica, Química e de Produção, e outras informacionais e comunicativas, como em Design de Produto e Gráfico. É nesse contexto no qual esta pesquisa se debruça ante uma demanda do Inmetro na avaliação de usabilidade de embalagens. Durante o desenvolvimento desta, foi feito o uso de padrões nacionais de qualidade e de segurança para definir o campo de estudo, selecionar as baterias de teste e as diretrizes regulatórias, além de escolher as quantidades de amostra e perfis. Porém, mesmo com a diversidade dessas normas estabelecidas pela ABNT (2020) e pela ISO (2020) existe ainda uma lacuna quanto às diretrizes que tratam da ergonomia e usabilidade de produtos não digitais, principalmente no que diz respeito à interação com usuários reais. Neste artigo, são analisados ​​três diferentes modelos de embalagens comuns a diferentes alimentos, de vinte fabricantes diferentes.

Demography and electrical energy in the economy of large Cameroonian cities
Authors: Mfewou Abdoulay
Published: August 2021

This article shows that Cameroon remains the second hydroelectric potential of Africa after the Democratic Republic of Congo. Started in the 1950s and developed in 2001 by the national policy, strategy and action plan for energy efficiency in the electricity sector in Cameroon with the construction of hydroelectric dams and thermal power plants, the result of this policy Slow is the persistence of difficulties in supplying electrical energy, which leads to continuous load shedding on the one hand, and the limits linked to supplies in a context of increasing urbanization (2.5%) on the other. Although the correlation between population growth and energy consumption remains present for economic growth in cities, the rate of GDP is 5.77% and remains constant among other things, from the energy crisis in all cities of the country.

Introduction

La crise des opioïdes au Canada a coûté la vie à des milliers de personnes, mettant davantage en lumière que les blessures liées aux intoxications constituent un problème de santé publique important. Cependant, en Colombie-Britannique, où le taux de mortalité par surdose est le plus élevé au Canada, les études n’ont pas encore permis de déterminer quelles populations visitent le plus souvent les urgences pour une intoxication ni quelles substances sont le plus souvent en cause. L’objectif de cette étude était d’explorer ces lacunes après avoir élaboré une méthodologie pour calculer les taux de visite aux urgences en Colombie Britannique.

Méthodologie

Grâce à une nouvelle méthodologie élaborée dans cette étude, nous avons calculé les taux de visite aux urgences liée à une intoxication sur la période 2012-2013 à 2016-2017 par sexe, groupe d’âge, substance ayant mené à l’intoxication et statut socioéconomique. Les données relatives aux urgences proviennent du Système national d’information sur les soins ambulatoires et les données de population proviennent des profils de recensements de 2016 (ou 2011) de Statistique Canada.

Résultats

Au cours de la période étudiée, on estime qu’il y a eu 81 463 visites aux urgences en raison d’une intoxication (351,2 pour 100 000 habitants). Les nourrissons, les tout-petits, les jeunes et les personnes de 20 à 64 ans présentaient un risque élevé de visites aux urgences en raison d’une intoxication. Les taux les plus élevés touchaient les personnes vivant dans les quartiers les plus défavorisés sur le plan matériel (607,8 pour 100 000 habitants) ou social (484,2 pour 100 000 habitants). Au fil du temps, les intoxications causées par les narcotiques et les psychodysleptiques sont devenues de plus en plus fréquentes, l’alcool demeurant toujours un problème.

Conclusion

Nous avons élaboré et appliqué une méthodologie d’estimation des taux de visite aux urgences en Colombie-Britannique pour déterminer ceux liés à une intoxication au sein de divers groupes de population de la province. Maintenant que nous savons quelles populations sont les plus vulnérables aux intoxications en Colombie-Britannique, il faut déployer des efforts pour limiter les surdoses de drogues et les intoxications liées à une consommation excessive d’alcool afin de réduire les taux de ces blessures évitables.
Améliorer l’aide à l’arrêt du tabagisme offerte aux fumeurs québécois : évaluation de la ligne téléphonique d’aide du Québec
Authors: Stich Christine , Lasnier Benoit , Lo Ernest
Published: August 2021

Introduction

Les lignes téléphoniques d’aide à l’arrêt du tabagisme constituent une intervention importante et largement répandue en matière de soutien aux fumeurs dans leur démarche d’arrêt du tabagisme et d’encouragement à obtenir des services de traitement. Au Québec, la ligne téléphonique d’aide à l’arrêt du tabagisme, la ligne J’ARRÊTE, est en service depuis 2002. Cette étude vise à évaluer la portée du traitement, à décrire les caractéristiques des appelants et à présenter les données issues des mesures des résultats.

Méthodologie

Nous avons recueilli des données à l’évaluation initiale en vue d’estimer le volume de nouveaux appelants, les caractéristiques des appelants et la portée du traitement. Nous avons appliqué un modèle quasi expérimental à groupe unique pour estimer, lors du suivi à 6 mois, les taux d’arrêt du tabagisme à 30 jours et à 6 mois. Les données initiales ont été recueillies après de 1 292 nouveaux appelants de la ligne d’aide de 18 ans et plus, sur une période d’un an.

Résultats

Les résultats indiquent que le service a permis de rejoindre 9 fumeurs québécois sur 10 000. Par rapport à la population totale de fumeurs au Québec, l’utilisation de la ligne d’aide était proportionnellement plus élevée chez les femmes, chez les personnes de 55 ans et plus et chez les personnes ayant une scolarité égale ou inférieure au diplôme d’études secondaires. Lors du suivi, le taux d’abstinence ponctuelle à 30 jours était de 26,7 %, tandis que le taux d’abstinence continue à 6 mois était de 18,8 %.

Conclusion

D’après ces résultats, la ligne d’aide a permis d’aider les appelants à cesser de fumer. Ces résultats sont conformes aux résultats d’études portant sur d’autres lignes d’aide au Canada et aux États-Unis. Cependant, par comparaison, la portée de la ligne d’aide pour fumeurs est limitée, ce qui donne à penser que des investissements supplémentaires dans les efforts de promotion et dans la recherche de façons de joindre les populations ayant pas ou peu accès au service permettraient d’accroître les bénéfices pour la santé publique.
