[Decision-making process and evaluation of public health interventions]. / Démarche décisionnelle et évaluation des interventions de santé publique.

OBJECTIVE: We have designed a methodological framework for experts involved in the support of decision-making in public health interventions. METHODS: The methodological framework consists of four elements: 1) A series of nine questions, formulated in non-technical terms, relevant to assessment of the usefulness of an intervention, at a given time in a given context; 2) Translation of these questions into concepts related to the evaluation of interventions (definition of the intervention, its target and objective, potential and actual effectiveness, safety, efficiency, and equity); 3) Logical organization of the information needed to address and answer the questions; and 4) An algorithm to translate the available information into recommendations on the real usefulness of the intervention in the context in which the questions were raised. RESULTS: Each step is illustrated by questions raised about road safety interventions, screening, blood transfusion and measures proposed during the COVID-19 pandemic. CONCLUSION: Decision-making can be facilitated if experts provide decision-makers with a formal summary of the strengths and weaknesses of existing knowledge, based on an analysis of all facets of an intervention's potential usefulness.

Predictors of Tri-council Funding Among Nutrition Researchers in Canada.

Purpose: Barriers in research for women and dietitians have been documented. We sought to describe tri-council funding awarded within the nutrition discipline according to institution type, academic rank, gender, dietitian status, and primary research methods used.Methods: Using an online search methodology, faculty members with research appointments were identified from nutrition departments offering accredited dietetic programs and/or at Canada's collective of research-intensive universities known as U15. All data regarding faculty members, their institutions, and funding were collected through publicly available websites and Scopus. Tri-council funding associated with the nominated principal investigator, from a 5-year period, 2013-2014 to 2017-2018, was extracted. Binary logistic regression was used to test for predictors of receiving any tri-council operating funds within the 5-year period.Results: Faculty members (n = 237) from 21 institutions were identified for inclusion. Those from U15 institutions, at the full professor rank, nondietitians, men, and those who engaged in primarily quantitative research methods (vs. qualitative or mixed-methods) were significantly more likely to hold any tri-council funding during the eligible period. Dietitians (n = 76) were significantly less likely to hold tri-council funding, independent of institution, rank, gender, and primary research methods utilized.Conclusions: The apparent under-funding of academic dietitians from federal tri-council sources requires exploration.

Knowledge exchange between patient and pharmacist: A mixed methods study to explore the role of pharmacists in patient education and counseling in asthma and pulmonary arterial hypertension.

OBJECTIVES: To better understand the role of pharmacists in patient education and counselling: describe the perception of knowledge exchange (KE) between asthma/pulmonary arterial hypertension patients and pharmacists (hospital/community) according to four dimensions (4C-typology): cure (C1), care (C2); coordination/supply chain (C3), characteristics of the pathophysiology/disease mechanisms (C4); factors correlated with KE. METHODS: A mixed methods approach was used. Part A: data from semi-structured patient interviews were processed (thematic analysis), and a questionnaire developed. Part B: completed patient questionnaires were processed by correspondence factor analysis. RESULTS: KE (4C-typology) was correlated with pathology, disease severity, disease duration, age, hospital/community pharmacist. Patients expected pharmacists to provide C2/C3 services. KE with pharmacists covered C1/C2/C3, and with physicians, C1/C2/C4. While patients perceived KE as a means of self-learning to improve self-care skills, the two-way nature meant it provided specific experiential information feedback to pharmacists. CONCLUSIONS: This 4C-typology provides a holistic framework for optimising the pharmacists' role in education and counselling of patients with chronic diseases.

Recombinase polymerase amplification in the molecular diagnosis of microbiological targets and its applications.

Since the introduction of the polymerase chain reaction (PCR) technique in 1983, nucleic acid amplification has permeated all fields of biological science, particularly clinical research. Despite its importance, PCR has been restricted to specialized centers and its use in laboratories with few resources is limited. In recent decades, there has been a notable increase in the development of new isothermal technologies for molecular diagnosis with the hope of overcoming the traditional limitations of the laboratory. Among these technologies, recombinase polymerase amplification (RPA) has a wide application potential because it does not require thermocyclers and has high sensitivity, specificity, simplicity, and detection speed. This technique has been used for DNA and RNA amplification in various pathogenic organisms such as viruses, bacteria, and parasites. In addition, RPA has been successfully implemented in different detection strategies, making it a promising alternative for performing diagnoses in environments with scarce resources and a high burden of infectious diseases. In this study, we present a review of the use of RPA in clinical settings and its implementation in various research areas.

From the voices of supervisees: A theoretical model of reflective supervision (Part II).

Empirical study of reflective supervision/consultation (RS/C) has been gaining ground over the past decade. However, much of this literature is focused on the supervisor perspective of what RS/C is, what makes it effective, and how it impacts the work of the supervisee. This paper, Part II of a two-part series, presents a theoretical model of RS/C that was developed from the perspectives and experiences of supervisees who work with infants, young children, and families and participate in either group or individual RS/C. This qualitative study built upon themes that emerged from data obtained from 50 IECMH professionals in the United States who participated in focus groups or individual interviews aimed at investigating their experiences of RS/C. Data were analyzed using a Grounded Theory approach. A developmental and ecological theoretical model of RS/C emerged from the data that includes three domains of influence - individual, relational, and contextual - on the supervisee's capacity to understand and use their experience of RS/C in their work. These novel data contribute to our understanding of RS/C from the supervisee perspective. The theoretical model provides a framework from which to investigate outcomes, train supervisors and supervisees, and advocate for RS/C within agencies and programs.

El estudio empírico de la supervisión/consulta con reflexión (RS/C) ha estado ganando terreno en la pasada década. Sin embargo, la mayoría de estas publicaciones se enfocan en la perspectiva del supervisor acerca de lo que RS/C es, lo que la hace eficaz y qué impacto tiene en el trabajo del supervisado. Este ensayo, Parte II de una serie de dos partes, presenta un modelo teórico de RS/C que se desarrolló a partir de las perspectivas y experiencias de los supervisados que trabajan con infantes, niños pequeños y familias y participan en RS/C de grupo o individual. Este estudio cualitativo tuvo como base los temas que surgieron de datos obtenidos de cincuenta profesionales de IECMH en los Estados Unidos, quienes participaron en grupos de enfoque o entrevistas individuales dirigidas a investigar sus experiencias de RS/C. La información se analizó usando un acercamiento de Teoría Fundamentada. De la información surgió un modelo teorético de desarrollo y ecológico de RS/C que incluye tres dominios de influencia - individual, relacional y contextual - sobre la capacidad de los supervisados de comprender y usar sus experiencias de RS/C en el trabajo. Esta novedosa información contribuye a nuestro conocimiento de RS/C desde la perspectiva del supervisado. El modelo teórico provee un marco de trabajo desde el cual se investigan los resultados, se entrenan los supervisores y supervisados, y se aboga por la inclusión de RS/C dentro de agencias y programas.

Les études empiriques de la supervision / consultation réflexive (RS/C pour reprendre l'anglais) a gagné du terrain ces dix dernières années. Cependant beaucoup de ces recherches sont focalisées sur la perspective du superviseur de ce qu'est la RS/C, ce qui rend la rend efficace, et comment elle influence le travail de la personne supervisée. Cet article, la deuxième partie d'une série en deux parties, présente un modèle théorique de la RS/C qui a été développé à partir des perspectives et des expériences de personnes supervisées travaillant avec des nourrissons, de jeunes enfants et des familles et participant à soit une RS/C de groupe ou individuelle. Cette étude qualitative s'est bâtie sur des thèmes ayant émergé de données obtenues de cinquante professionnels de la santé mentale du nourrisson et de la petite enfance se trouvant aux Etats-Unis qui ont participé à des groupes de discussion ou à des entretiens individuels destinés à enquêter sur leurs expériences de la RS/C. Les données ont été analysées en utilisant une approche de Théorie Ancrée. Un modèle théorique développemental et écologique de RS/C a émergé des données, incluant trois domaines d'influence - individuel, relationnel, et contextuel - sur la capacité de la personne supervisée à comprendre et à utiliser ses expériences de la RS/C dans le travail. Ces nouvelles données contribuent à notre compréhension de la RS/C du point de vue de la personne supervisée. Le modèle théorique offre une structure à partir de laquelle on peut faire des recherches sur les résultats, former les superviseurs et les personnes supervisées, et se faire les avocats de la RS/C au sein des agences et des programmes.

From the voices of supervisees: What is reflective supervision and how does it support their work? (Part I).

Reflective supervision/consultation (RS/C) is a relationship for learning that embraces reflection and reflective practice strategies. It is considered best practice within the infant and early childhood mental health (IECMH) field. Based on research with supervisors, essential components of RS/C have been operationalized and used to develop evaluative tools. Little is known, however, about the essential components that supervisees find most useful. This paper, part I of a two-part series, describes the essential components that supervisees identify as fundamental and ways they believe their work is supported by participation in RS/C. Fifty IECMH professionals located in the United States who received RS/C participated in focus groups or individual interviews. Data were analyzed using a Grounded Theory approach. Essential components of RS/C from the supervisee perspective included supervisee feelings of safety, the development of trust, holding a non-judgmental stance, being available and present, and consistency and predictability. Additionally, supervisees identified outcomes of RS/C that included components of professional wellness, personal growth, and infant and family engagement. This study adds the supervisee's voice to the identification and operationalization of essential RS/C components and elucidates outcomes of RS/C that supervisees view as connected to their professional role.

La supervisión/consulta con reflexión (RS/C) es una relación para el aprendizaje (Fenichel, 1992) que abarca la reflexión y las estrategias de reflexión en la práctica. La misma es considerada como una de las buenas prácticas dentro del campo de la salud mental del infante y la temprana niñez (IECMH). Con base en la investigación con supervisores, los componentes esenciales de RS/C han sido puestos en operación y usados para desarrollar herramientas de evaluación. Sin embargo, poco se sabe acerca de los componentes esenciales que los supervisados ven como los más útiles. Este ensayo, primera parte de una serie de dos partes, describe los componentes esenciales que los supervisados identifican como fundamentales y las maneras como ellos creen que su trabajo es apoyado por la participación en RS/C. Cincuenta profesionales de IECMH que recibieron RS/C participaron en grupos de enfoque o entrevistas individuales. Se analizaron los datos usando un acercamiento de la Teoría Fundamentada. Entre los componentes esenciales de RS/C desde la perspectiva del supervisado se incluyen los sentimientos de seguridad del supervisado, el desarrollo de la confianza, el mantener una actitud imparcial, estar disponible y presente, y consistencia y previsibilidad. Adicionalmente, los supervisados identificaron resultados de RS/C que incluyen componentes de bienestar profesional, crecimiento personal, así como la participación del infante y la familia. Este estudio agrega la voz del supervisado a la identificación y funcionamiento de los componentes esenciales de RS/C y dilucida resultados de RS/C que los supervisados ven como conectados con su papel profesional.

La supervision / consultation réflexive (RS/C pour reprendre l'anglais) est une relation d'apprentissage (Fenichel, 1992) qui embrasse la réflexion et des stratégies de pratique réflective. Elle est considérée comme étant la meilleure pratique au sein du domaine de la santé mentale du nourrisson et de la petite enfance. A partir des recherches avec des superviseurs les composants essentiels de la RS/C ont été opérationnalisés et utilisés pour développer des outils évaluatifs. On sait peu de choses, cependant, sur les composants essentiels que les personnes supervisées estiment être les plus utiles. Cet article, la première partie d'une série de deux parties, décrit les composants essentiels que les personnes supervisées identifient comme étant fondamentaux et les manières dont ils estiment que leur travail est soutenu par la participation à la RS/C. Cinquante professionnels de la santé mentale du nourrisson et de la petite enfance se trouvant aux Etats-Unis et ayant reçu la RS/C ont participé à des groupes de discussion ou à des entretiens individuels. Les données ont été analysées en utilisant une approche de Théorie Ancrée. Les composants essentiels à la RS/C du point de vue des personnes supervisées ont inclus le sentiment de sûreté de la personne supervisée, le développement de la confiance, le fait de ne pas juger, le fait d'être disponible et présent, ainsi que la cohérence et la prévisibilité. De plus les personnes supervisées ont identifié des résultats de la RS/C qui ont inclus des composants de bien-être professionnel, d'épanouissement personnel et d'engagement avec le nourrisson et la famille. Cette étude ajoute la voix de la personne supervisée à l'identification et à l'opérationnalisation des composants essentiels de la RS/C et élucide les résultats de la RS/C que les personnes supervisées considèrent comme étant lié à leur rôle professionnel.

[Realist protocol for implementing integrated care pathways in France (waiver 51 LFSS 2018)]. / Évaluer autrement les parcours de soins coordonnés article 51 LFSS 2018 : une innovation, les protocoles réalistes.

The paradox of real world researches supposedly conducted in real life is that they did not succeeded in freeing themselves from the techniques of the randomised trials which they pretended to escape. In the successionist perspective of classical experimental or quasi-experimental methods, the cause always precedes the effect in a linear manner, and any interference that is likely to threaten the stability of this relationship must be neutralised by mobilising the appropriate statistical techniques. In complex systems where everything moves at the same time due to multiple interrelationships that make it impossible to construct a counterfactual, these elements are no longer considered as confounding factors that need to be controlled, but as decisive factors in the smooth running of the experiment. The protocol presented in this article proposes an alternative evaluative technique mobilising the teachings of critical realism, which seems to us to be the most appropriate for understanding what happens "in the black box" recording the events that occur between the implementation of the Article 51 experiments and the observed results. The role of the evaluator is to put the actors back at the heart of the change, since it is achieved (or not) according to their reactions and the contextual elements. This credible explanatory theory allows us to understand: how does it work? For whom does it work? Why do losers lose, winners win? and under what circumstances?

Parent engagement in an original and culturally adapted evidence-based parenting program, Legacy for Children™.

Legacy for Children™ (Legacy) is an evidence-based program focused on promoting sensitive, responsive parenting for socioeconomically disadvantaged families. Legacy has recently been culturally and linguistically adapted for Spanish-monolingual Latino families and is being piloted in partnership with an early childhood education program. We conducted a mixed methods study to identify barriers and facilitators to engagement, using program monitoring data sources from both participant and group leader perspectives. We conducted qualitative analyses of open-ended data to identify distinct barriers (e.g., employment challenges, health-related challenges and appointments) and facilitators (e.g., other mothers in group, interest in program topics) to engagement that emerged across English and Spanish language curriculum versions; curriculum-specific barriers and facilitators were also documented. We interpret these findings in light of quantitative data on measures of engagement, showing that participants in the Spanish curriculum evidenced comparable levels of parent-group leader relationship quality relative to the English group, and higher levels of parent's group support/connectedness and overall satisfaction. These results offer promising considerations for optimizing families' engagement in parenting programs in the context of early care and education settings.

Legado para los Niños™ (Legado) es un programa basado en la evidencia que se centra en promover una crianza sensible y susceptible para familias con desventajas socioeconómicas. Recientemente, Legado se ha adaptado cultural y lingüísticamente para familias Latinas en las que sólo se habla español, y está siendo puesto en práctica experimental en asociación con un programa de educación en la temprana niñez. Llevamos a cabo un estudio con una variedad mixta de métodos para identificar obstáculos y promotores para ser incluidos usando recursos de información de la supervisión del programa provenientes de las perspectivas tanto de participantes como de líderes de grupo. Realizamos análisis cuantitativos de información no limitada de antemano para identificar diferentes obstáculos (v.g. dificultades de empleo, dificultades y citas relacionadas con la salud) y promotores (v.g. otras madres en el grupo, interés en los temas del programa) para ser incluidos los cuales surgieron a lo largo de las versiones curriculares del inglés y del español; también se documentaron los obstáculos y promotores relacionados con el currículo específico. Interpretamos estos resultados a la luz de la información cuantitativa sobre medidas de participación, mostrando que los participantes en el currículo en español demostraron comparables niveles de calidad de la relación progenitor-líder de grupo en relación con el grupo de inglés, y más altos niveles de apoyo del grupo a los progenitores y satisfacción en general. Estos resultados ofrecen consideraciones prometedoras para lograr una óptima participación de las familias en programas de crianza en el contexto de escenarios de cuidado y educación tempranos.

Le programme Legacy for ChildrenTM (Legacy) est un programme factuel se concentrant sur la promotion d'une parentage sensible et réactif pour des familles de milieu socioéconomique défavorisé. Legacy a récemment été culturellement et linguistiquement adapté aux familles Latino américaines, en espagnol, et se trouve testé en partenariat avec un programme éducatif de la petite enfance. Nous avons procédé à une étude au moyen de méthodes mixtes afin d'identifier les barrières qui existent et freinent l'engagement, ainsi que ce qui facilite l'engagement, en utilisant des sources de données d'évaluation du programme à la fois de la perspective des participants et du leader de groupe. Nous avons fait des analyses qualitatives de données ouvertes afin d'identifier des barrières précises (i.e. les défis du chômage, les défis liés à la santé et aux rendez-vous) et les aspects facilitateurs (i.e. autres mères dans le groupe, intérêt pour les sujets du programme) pour l'engagement qui ont émergé au travers des deux versions, la version en anglais et la version en espagnol. Les barrières tenant au curriculum et aux facilitateurs ont aussi été répertoriées. Nous avons interprété ces résultats à la lumière de données quantitatives sur des mesures d'engagement, montrant que les personnes participant au curriculum espagnol faisaient preuve de niveaux comparables de qualité de la relation parent-meneur de groupe que le groupe anglais, et de niveaux plus élevés de soutien/connexion et de satisfaction générale du groupe parent. Ces résultats offrent des considérations prometteuses pour l'optimisation de l'engagement des familles dans des programmes de parentage dans le contexte du soin précoce et de l'éducation de la petite enfance.

Validity and reliability of methods to microscopically detect and quantify malaria parasitaemia.

OBJECTIVES: The recommended microscopy method by WHO to quantify malaria parasitaemia yields inaccurate results when individual leucocyte (WBC) counts deviate from 8000 leucocytes/µl. A method avoiding WBC count assumptions is the Lambaréné method (LAMBA). Thus, this study compared validity and reliability of the LAMBA and the WHO method. METHODS: Three methods for counting parasitaemia were applied in parallel in a blinded assessment: the LAMBA, the WHO method using a standard factor of 8000 leucocytes/µl ['simple WHO method' (sWHO)] and the WHO method using measured WBC counts ['accurate WHO method' (aWHO)]. Validity was assessed by comparing LAMBA and sWHO to the gold standard measurement of aWHO. Reliability was ascertained by computation of intraclass correlation coefficients (ICCs). RESULTS: 787 malaria-positive thick smears were analysed. Parasitaemia as determined by LAMBA and sWHO increasingly deviated from aWHO the more patients' WBCs diverged from 8000/µl. Equations of linear regression models assessing method deviation in percent from gold standard as function of WBC count were y = -0.00608x (95% CI -0.00693 to -0.00524) + 47.8 for LAMBA and y = -0.0125x (95% CI -0.01253 to -0.01247) + 100.1 for sWHO. Comparison of regression slopes showed that the deviation was twice as high for sWHO as for LAMBA (P < 0.001). ICCs were excellent (>90%) for both methods. CONCLUSIONS: The LAMBA has higher validity than the sWHO and may therefore be preferable in resource-limited settings without access to routine WBC-evaluation.

Randomized clinical trials and observational studies in the assessment of drug safety.

Randomized clinical trials are considered as the preferred design to assess the potential causal relationships between drugs or other medical interventions and intended effects. For this reason, randomized clinical trials are generally the basis of development programs in the life cycle of drugs and the cornerstone of evidence-based medicine. Instead, randomized clinical trials are not the design of choice for the detection and assessment of rare, delayed and/or unexpected effects related to drug safety. Moreover, the highly homogeneous populations resulting from restrictive eligibility criteria make randomized clinical trials inappropriate to describe comprehensively the safety profile of drugs. In that context, observational studies have a key added value when evaluating the benefit-risk balance of the drugs. However, observational studies are more prone to bias than randomized clinical trials and they have to be designed, conducted and reported judiciously. In this article, we discuss the strengths and limitations of randomized clinical trials and of observational studies, more particularly regarding their contribution to the knowledge of medicines' safety profile. In addition, we present general recommendations for the sensible use of observational data.

METHODOLOGICAL CONSIDERATIONS FOR HOME-VISITING RESEARCH IN TRIBAL COMMUNITIES.

Drawing on previous studies and the collective experience of conducting rigorous evaluations as part of the Tribal Maternal, Infant, and Early Childhood Home Visiting grants, we outline methodological considerations that will inform future research in tribal communities, particularly in the area of home visiting. The methodological issues we discuss are study design choices, measurement and data collection, and including community members in all aspects of the research.

[Early detection of mental health disorders at school: The Fil Harmonie pilot program]. / Détection précoce des troubles psychiques en milieu scolaire : le dispositif Fil Harmonie.

OBJECTIVE: Most psychiatric disorders arise during adolescence, a period of life during which school takes an important place. School in France has an official mission of health education and prevention, and early detection of mental disorders is part of these goals. The aim of this study is to describe an innovative service operating in Paris that helps educational staff to deal with students having psychological or psychiatric symptoms. The Fil Harmonie program was launched in 2011. It consists of a telephone line available to all educational staff working for high schools in Paris. METHODS: When in need of assistance, a member of the educational staff can call the dedicated hotline and expose the situation of their student to a trained psychologist. Over the course of the study, data concerning these phone calls were collected such as: socio-demographic characteristics of the student, the reason behind the call, the caller's professional role within the school, and care pathway information. All data collected during the phone calls were anonymized and computerized. We performed an observational descriptive study based on this data by using mixed methods: we integrated quantitative analysis and qualitative research in order to provide a better understanding of the Fil Harmonie program. RESULTS: Between 18 September 2013 and 12 May 2014, the Fil Harmonie program handled 68 calls from educational staff. Students concerned by the calls were aged between 11 and 22 and the average age was 17.3 years. Over half (52.5%) of the pupils concerned had never seen a mental health professional before the call. In more than 70% of cases, the caller was a school nurse while other professionals such as teachers or headmasters represented only a minority of the callers. Approximately two thirds (67.2%) of students were described by the caller as socially isolated and 48.2% were described as sad or anhedonic. One out of four (26.7%) had repeated a school year at least once, and 55.9% of young people for whom a member of staff contacted Fil Harmonie had been missing class. In 56.7% of cases, there had been no contact with the student's family about the psychological situation. The qualitative analysis particularly highlighted the complexity of the collaboration between the family and the educational staff. CONCLUSION: Schooling is an important opportunity to seize in mental health regarding early detection and access to care. By fostering collaboration between educational professionals and mental health services, Fil Harmonie meets a public health objective of prevention and should contribute to the reduction of care delays thus leading to better treatment outcome. Our study shows that such programs are feasible and answer a real need in our current health care system.

Estimating the number of female sex workers in Côte d'Ivoire: results and lessons learned.

OBJECTIVE: To report on the results of three size estimations of the populations of female sex workers (FSW) in five cities in Côte d'Ivoire and on operational lessons learned, which may be relevant for key population programmes in other parts of the world. METHODS: We applied three methods: mapping and census, capture-recapture and service multiplier. All were applied between 2008 and 2009 in Abidjan, San Pedro, Bouaké, Yamoussoukro and Abengourou. RESULTS: Abidjan was the city with the highest number of FSW by far, with estimations between 7880 (census) and 13 714 (service multiplier). The estimations in San Pedro, Bouaké and Yamoussoukro were very similar, with figures ranging from 1160 (Yamoussoukro, census) to 1916 (San Pedro, capture-recapture). Important operational lessons were learned, including strategies for mapping, the importance of involving peer sex workers for implementing the capture-recapture and the identification of the right question for the multiplier method. CONCLUSIONS: Successful application of three methods to estimate the population size of FSW in five cities in Côte d'Ivoire enabled us to make recommendations for size estimations of key population in low-income countries.

Impact of China's essential medicines scheme and zero-mark-up policy on antibiotic prescriptions in county hospitals: a mixed methods study.

OBJECTIVE: To evaluate the impact of the national essential medicines scheme and zero-mark-up policy on antibiotic prescribing behaviour. METHODS: In rural Guangxi, a natural experiment compared one county hospital which implemented the policy with a comparison hospital which did not. All outpatient and inpatient records in 2011 and 2014 were extracted from the two hospitals. Primary outcome indicator was antibiotic prescribing rate (APR) among children aged 2-14 presenting in outpatients with a primary diagnosis of upper respiratory tract infection (URTI). We organised independent physician reviews to determine inappropriate prescribing for inpatients. Difference-in-difference analyses based on multivariate regressions were used to compare APR over time after adjusting potential confounders. We conducted 12 in-depth interviews with paediatricians, hospital directors and health officials. RESULTS: A total of 8219 and 4142 outpatient prescriptions of childhood URTIs were included in the intervention and comparison hospitals, respectively. In 2011, APR was 30% in the intervention and 88% in the comparison hospital. In 2014, the intervention hospital significantly reduced outpatient APR by 21% (95% CI:-23%, -18%), intravenous infusion by 58% (95% CI: -64%, -52%) and prescription cost by 31 USD (95% CI: -35, -28), compared with the controls. We collected 251 inpatient records, but did not find reductions in inappropriate antibiotic use. Interviews revealed that the intervention hospital implemented a thorough antibiotics stewardship programme containing training, peer review of prescriptions and restrictions for overprescribing. CONCLUSION: The national essential medicines scheme and zero-mark-up policy, when implemented with an antimicrobial stewardship programme, may be associated with reductions in outpatient antibiotic prescribing and intravenous infusions.

A review of the current state of antimicrobial susceptibility test methods for Brachyspira.

The re-emergence of swine dysentery (Brachyspira-associated muco-haemorrhagic colitis) since the late 2000s has illuminated diagnostic challenges associated with this genus. The methods used to detect, identify, and characterize Brachyspira from clinical samples have not been standardized, and laboratories frequently rely heavily on in-house techniques. Particularly concerning is the lack of standardized methods for determining and interpreting the antimicrobial susceptibility of Brachyspira spp. The integration of laboratory data into a treatment plan is a critical component of prudent antimicrobial usage. Therefore, the lack of standardized methods is an important limitation to the evidence-based use of antimicrobials. This review will focus on describing the methodological limitations and inconsistencies between current susceptibility testing schemes employed for Brachyspira, provide an overview of what we do know about the susceptibility of these organisms, and suggest future directions to improve and standardize diagnostic strategies.

[Health care, needs and barriers in seeking medical care for global health and sexual and reproductive health, among students from Félix Houphouët-Boigny University, Abidjan, Côte d'Ivoire]. / Recours aux soins de santé globale et de santé sexuelle et reproductive, chez les étudiants de l'université Houphouët-Boigny, Abidjan, Côte d'Ivoire.

BACKGROUND: In Ivory Coast, little is known about health needs and health access barriers among young people. The aim of this study was to describe health provision, health needs and barriers when seeking medical care, with an emphasis on sexual and reproductive health, and the acceptability of a medical examination for students attending their first year at the Houphouët-Boigny University, Abidjan, Ivory Coast. METHODS: We conducted a representative cross-sectional study among second year students who were selected by two-stage equiprobable random sampling. In-depth interviews were conducted among students and the university health center staff. RESULTS: Five hundred and forty three students (322 men and 221 women) answered a questionnaire (participation rate 98.4%). Among women who ever had sex, 38.4% (95%CI [30.5%-47.0%]) had unmet contraception needs and 31.2% [23.7%-40.0%] had experienced an unwanted pregnancy. Fear about impaired fertility was the leading reason for non-use of hormonal contraception, the method of choice among most students. The main health problems among students, by order of frequency were malaria (54.3%), respiratory infection (44.6%), constipation (28.0%) and psychological problems (25.9%). High cost perception of services offered, despite their gratuity, were the main barriers against access to the university health center, indicating a lack of communication about this structure and its services. The majority of students favored the establishment of a medical examination during the first year at the university. CONCLUSION: Establishing a medical examination would improve health center visibility. The following services could be offered: (i) HIV, chlamydia and gonorrhea screening, (ii) hepatitis B virus screening and vaccination, (iii) provision and information about contraceptive methods, (iv) presentation of the university health center services. Dedicated spaces where students could have access to information about health-related topics (e.g. sexuality, nutrition, depression) could complete the university's healthcare offer.

Tailored telephone counselling to increase participation of underusers in a population-based colorectal cancer-screening programme with faecal occult blood test: A randomized controlled trial.

BACKGROUND: Despite the involvement of general practitioners, the mailing of several recall letters and of the faecal occult blood test (FOBT) kit, the uptake remains insufficient in the French colorectal cancer-screening programme. Some studies have demonstrated a greater efficacy of tailored telephone counselling over usual care, untailored invitation mailing and FOBT kit mailing. We evaluated the feasibility and the effectiveness of telephone counselling on participation in the population-based FOBT colorectal cancer-screening programme implemented in Alsace (France). METHODS: Underusers were randomized into a control group with untailored invitation and FOBT kit mailing (n=19,756) and two intervention groups for either a computer-assisted telephone interview (n=9367), system for tailored promotion of colorectal cancer screening, or a telephone-based motivational interview (n=9374). RESULTS: Only 5691 (19.9%) people were actually counseled, so that there was no difference in participation between the intervention groups taken together (13.9%, 95% confidence interval [CI] [13.5-14.4]) and the control group (13.9%, 95% CI [13.4-14.4]) (P=1.0) in intent-to-treat analysis. However, in per-protocol analysis, participation was significantly higher in the two intervention groups than in the control group (12.9%, 95% CI [12.6-13.2]) (P<0.01), with no difference between computer-assisted telephone interview (24.6%, 95% CI [22.7-26.4]) and motivational interview (23.6%, 95% CI [21.8-25.4]) (P=0.44). CONCLUSION: There was no difference of effectiveness between tailored telephone counselling and untailored invitation and FOBT kit mailing on participation of underusers in an organized population-based colorectal cancer screening programme. A greater efficacy of telephone counselling, around twice that of invitation and FOBT kit mailing, was observed only in people who could actually be counseled, without difference between computer-assisted telephone interview and motivational interview. However, technical failures hampered telephone counselling, so that there was no difference in intent-to-treat analysis. The rate of technical success of telephone interviews should be evaluated, and enhanced if insufficient, before implementation of telephone counselling in population-based cancer screening programmes.

[The evaluation of pharmacological drugs, medical devices, and non-pharmacological or public health interventions: Experimental design limitations. Moving towards new methods?] / Évaluer les effets d'un médicament, de dispositifs médicaux et d'interventions non médicamenteuses ou de santé publique : limites de l'essai expérimental. Vers de nouvelles méthodes ?

In the field of health, evidence-based medicine and associated methods like randomised controlled trials (RCTs) have become widely used. RCT has become the gold standard for evaluating causal links between interventions and health results. Originating in pharmacology, this method has been progressively expanded to medical devices, non-pharmacological individual interventions, as well as collective public health interventions. Its use in these domains has led to the formulation of several limits, and it has been called into question as an undisputed gold standard. Some of those limits (e.g. confounding biases and external validity) are common to these four different domains, while others are more specific. This paper describes the different limits, as well as several research avenues. Some are methodological reflections aiming at adapting RCT to the complexity of the tested interventions, and at overcoming some of its limits. Others are alternative methods. The objective is not to remove RCT from the range of evaluation methodologies, but to resituate it within this range. The aim is to encourage choosing between different methods according to the features and the level of the intervention to evaluate, thereby calling for methodological pluralism.

Efficacy and community effectiveness of larvivorous fish for dengue vector control.

OBJECTIVE: To evaluate the efficacy and community effectiveness of larvivorous fish for the control of dengue vectors and dengue transmission, when used as a single agent or in combination with other vector control methods. METHOD: Comprehensive literature search of published and grey literature using PubMed, EMBASE (DMDI), Web of Science, WHOLIS, WILEY, LILACS, GIFT, Cochrane Library, ELDIS, New York Academy of Medicine Grey Literature Report and Google. All results were checked for duplicates and examined for eligibility. Methodological quality of the studies was assessed using RoBANS. RESULTS: Thirteen articles were considered eligible for inclusion. Incorporating a wide range of interventions and outcome measures, three were efficacy studies and 10 assessed community effectiveness. None of the studies were randomised or cluster-randomised controlled trials. All three efficacy studies and seven community effectiveness studies investigated fish as a single agent. All efficacy studies reported elimination of Aedes larvae from treated containers, while community effectiveness studies reported reductions in immature vector stages, two of which also detected a continuous decline over 2 years. An impact on adult mosquitoes was shown in only two community effectiveness studies. Reductions in dengue cases following intervention were reported in two studies, but it was not possible to attribute this to the intervention. CONCLUSION: While the use of larvivorous fish as a single agent or in combination with other control measures could lead to reductions in immature vector stages, considerable limitations in all the studies restricted any conclusions with respect to the evaluation of community effectiveness. Evidence for the community effectiveness of larvivorous fish as a single agent remains minimal and cluster-randomised controlled studies that include the assessment of impact on dengue are recommended.
