Assessing medication adherence: options to consider.

Background Adherence to chronic therapy is a key determinant of patient health outcomes in chronic disease. However, only about 50 % of patients adhere to chronic therapy. One of the challenges in promoting adherence is having an accurate understanding of adherence rates and the factors that contribute to non-adherence. There are many measures available to assess patient medication adherence. Aim of the review This review aims to present the commonly used indirect methods available for measuring medication adherence in routine healthcare and research studies. Method A literature review on medication adherence measures in patient populations with chronic conditions taking chronic medications was conducted through Medline (2003-2013). A complementary manual search of references cited in the retrieved studies was performed in order to identify any additional studies. Results Of the 238 initial Medline search results, 57 full texts were retrieved. Forty-seven articles were included as a result of the manual search. Adherence measures identified were: self-report (reported in 50 publications), electronic measures (33), pharmacy refills and claims data (26) and pill counts (25). Patient self-report, electronic measures, pharmacy refill and claims data were the most commonly used measures of adherence in research, routine practice, epidemiological and intervention studies. These methods, and their strengths and limitations have been described in this paper. Conclusion A multitude of indirect measures of adherence exist in the literature, however, there is no "gold" standard for measuring adherence to medications. Triangulation of methods increases the validity and reliability of the adherence data collected. To strengthen the adherence data collected and allow for comparison of data, future research and practice interventions should use an internationally accepted, operational standardized definition of medication adherence and clearly describe the medication adherence methods used.

Aptitude à la conduite, pathologies psychiatriques et psychotropes chez la personne âgée [Driving ability, mental illness and psychotropic medication in the elderly].

Fitness to drive in elderly drivers is most commonly discussed with a focus on cognitive impairment. Therefore, this article is focussing on mental illness and the use of psychotropic drugs in elderly drivers, which can both interfere with fitness to drive. Based on a detailed literature review and on clinical judgement, we propose signposts and "red flags" to judge the individual risks. Health professionals dealing with elderly patients should in particular be aware of the dangers related to cumulative risks and need to inform the patients appropriately. For medico-legal reasons the information provided to patients must be written down in the medical record. Individual counselling is important as fitness to drive is a complex topic.

Les parlementaires suisses entre démocratisation et professionnalisation (1910-2010). Biographie collective des élus fédéraux et réformes du Parlement helvétique

Notre travail de thèse vise à analyser, d'une part, les principales réformes du Parlement fédéral adoptées au cours du 20e siècle et, d'autre part, l'évolution du profil sociographique pour six cohortes d'élus fédéraux (1910, 1937, 1957, 1980, 2000 et 2010), sous l'angle de sa démocratisation et de sa professionnalisation. La thèse comprend trois axes de recherche principaux. Premièrement, nous nous penchons sur les deux réformes institutionnelles censées favoriser la démocratisation du recrutement parlementaire, à savoir l'adoption de la proportionnelle pour l'élection du Conseil national en 1918 et l'introduction du suffrage féminin à l'échelon fédéral en 1971. Nous abordons également les réformes du Parlement visant, depuis les années 1970, à sa revalorisation et à sa professionnalisation. Le deuxième axe porte sur la réalisation d'un portrait collectif des élus fédéraux pour la période 1910-1980, dans le but de vérifier l'impact des réformes des règles électorales (proportionnelle et suffrage féminin) sur le profil des députés et sénateurs. Enfin, dans le troisième axe, nous abordons les transformations du profil socio-professionnel des parlementaires pendant la période plus récente (1980-2010), en lien avec la professionnalisation accrue de l'Assemblée fédérale et les changements des rapports de force partisans. Nos résultats permettent de mettre en évidence plusieurs éléments de continuité (prédominance de la catégories des indépendants, notamment des avocats, des chefs d'entreprise et des agriculteurs, et sous-représentation des salariés du secteur public ; fort ancrage local), ainsi que certains facteurs de rupture (présence accrue des femmes, moindre importance de la carrière militaire). D'autres changements dans le profil sont liés au processus récent de professionnalisation, contesté et inachevé, qui a favorisé néanmoins l'émergence de nouveaux profils sociologiques d'élus, en termes de formation, de profession (apparition du groupe des parlementaires professionnels) et de cumul des mandats économiques et politiques, avec cependant de fortes variations entre les partis et entre les deux Chambres. - Our PhD thesis aims at analysing, on the one hand, the main reforms of the Federal Parliament adopted during the 20th century and, on the other hand, the evolution of sociographical profile for six cohorts of Swiss MPs (1910, 1937, 1957, 1980, 2000 and 2010) in terms of their democratization and professionalization. Our research is composed of three main parts. Firstly, we analyse two institutional reforms which intended to promote the democratization of parliamentary recruitment, namely the adoption of proportional representation (PR) in 1918 for the election of the National Council and the introduction of women's suffrage at the federal level in 1971. We also deal with parliamentary reforms that, since the 1970s, have aimed at reasserting the political status of the Federal Assembly and at professionalizing its members. Secondly, we carry out a collective biography of Swiss MPs during the period 1910-1980, in order to verify the impact of electoral reforms (PR and women's suffrage) on the profiles of deputies and senators. Finally, we discuss the transformation of the MPs' socio-_professional profiles during the recent period (1980-2010) in connection with the increased professionalization of the Federal Assembly and the changes of the power relations within the Parliament. Our results allow us to highlight several elements of continuity (the predominance of self-employed persons, especially lawyers, business managers and farmers, and the underrepresentation of public employees; stronger background in local politics), as well as some factors of discontinuity (increased presence of women and lesser importance of the military career). Other changes of the parliamentarians' profile are related to the recent process of professionalization. Although contested and unfinished, it has promoted new sociological profiles in terms of educational background, profession (growth of the professional parliamentarians) and number of political and economic mandates held simultaneously, however with important variations between parties and between Lower and Upper House.

The economics of anti-parasite defences in animal societies

RESUME : De nombreuses espèces animales vivent en groupe. Du simple grégarisme aux colonies hautement intégrées de fourmis, la vie sociale a atteint des degrés divers de complexité. Les nombreuses interactions entre membres d'une société favorisent la transmission de parasites. Cela représente un coût potentiel de la vie sociale. Cette thèse s'intéresse aux défenses permettant de réduire le coût du parasitisme dans les colonies de fourmis ainsi qu'à la manière dont le parasitisme a pu façonner certains aspects de ces sociétés. Les colonies de fourmis des bois (Forimica paralugubris) contiennent de grandes quantités de résine de conifères. Cette résine réduit la densité microbienne dans le nid et augmente la survie des ouvrières lors d'infections parasitaires. Dans cette thèse, nous montrons, d'une part, que les ouvrières collectent activement la résine et que ce comportement est plutôt préventif que curatif et, d'autre part, que la résine permet aux ouvrières une utilisation moindre de leurs défenses immunitaires. Ces résultats permettent de conclure que ce comportement réduit l'exposition au parasitisme et qu'il a une fonction adaptative. L'émergence d'un tel comportement de médication chez une espèce d'insectes sociaux illustre le fait que la socialité, bien yue provoquant une exposition accrue au parasitisme, permet également l'émergence de mécanismes sociaux de défense. II a été suggéré que la présence de plusieurs reines au sein d'un même nid (polygynie) améliore la résistance aux parasites en augmentant la diversité génétique au sein de la colonie. En accord avec cette hypothèse, nous montrons qu'une augmentation de la diversité génétique au sein de groupes expérimentaux de Formica selysi améliore leur survie lors d'une infection parasitaire. Cependant, nous suggérons également que sur le terrain, d'autres facteurs corrélés à la polygynie ont des effets antagoniques sur la résistance. Nous montrons par exemple que les ouvrières polygynes semblent avoir une capacité moindre à monter une réponse immunitaire. Certains aspects de la reproduction des fourmis ont pu également être façonnés par le parasitisme. L'accouplement n'a lieu que lors d'une courte période au début de la vie adulte, généralement à l'extérieur de la colonie. Les reines stockent ensuite le sperme et l'utilisent parcimonieusement au cours de leur vie alors que les males meurent rapidement. Nous montrons que les défenses immunitaires des reines de fourmis des bois (F. paralugubris) sont fortement affectées par l'accouplement. Ces modulations immunitaires sont probablement liées à une augmentation de l'exposition au parasitisme lors de l'accouplement ainsi qu'à des blessures copulatoires. I1 semble donc que l'accouplement soit accompagné de coûts immunitaires pour les reines. Dans son ensemble, cette thèse illustre la diversité des mécanismes de défenses contre les parasites dans les sociétés de fourmis. La vie sociale, en offrant un nouveau niveau d'interaction, permet en effet l'émergence d'adaptations originales. Cela explique probablement le grand succès écologique des espèces sociales. SUMMARY : Sociality is widespread among animals and has reached variable degrees of complexity, from loose social Groups to highly integrated ant colonies. The many interactions between members of a social group promote the spread of parasites, but social life also permits the evolution of original defence mechanisms. This thesis sheds light on how ant colonies defend themselves against parasites, and on how parasitism shapes certain aspects of these societies. Wood ants nests (Formica paralugubris) contain large amounts of conifer resin which reduces the microbial density in ant nests and enhances the survival of ants challenged by some pathogens. We show that resin is actively collected by workers and that resin collection is rather a prophylactic than a curative behaviour. Moreover, we suggest that resin reduces the use of the immune defences of workers. Altogether, these results indicate that the use of resin is a collective adaptation to prevent the spread of parasites. The emergence of medication in a social insect species illustrates that sociality does not only increase the exposure to parasites but also allows the emergence of social mechanisms to counter this threat. The number of reproducing queens per colony is a variable trait in ants. It has been suggested that polygyny (the occurrence of multiple queens within a colony), by increasing the colonial genetic diversity, improves disease resistance. In line with this hypothesis, we show that in a socially polymorphic ant (Formica selysi), an experimental increase of colony genetic diversity enhances disease resistance. However, we also suggest that factors covarying with queen number variation in the field have antagonistic effects on parasite resistance. We show for instance that polygyne workers seem to have lower immune defences. Parasites may also shape some aspects of ant queen reproductive biology. Ant queens mate at the beginning of their adult life, usually outside of the colony, and store sperm for several years to fertilize eggs. Males die shortly after mating and queens never remate later in life, which drastically reduces sexual conflicts. Moreover, mating and nest founding occur away from the collective defence mechanisms of the natal colony and might be associated with an increased risk of parasitism. We show that mating affects the immune defences of wood ant queens (F. paralugubris) in multiple ways that are consistent with mating wounds and increased risk of parasitism. We suggest that mating is associated with immunity costs in ants, despite the reduced level of sexual conflicts. Altogether, my thesis illustrates the diversity of anti-parasite mechanisms in ant societies. This sheds light on how sociality, by offering a new level of interactions, allows the evolution of original adaptations, which may explain the wide ecological success of social species.

Wood ants protect their brood with tree resin

Social insects use multiple lines of collective defences to combat pathogens. One example of a behav- ioural group defence is the use of antimicrobial plant compounds to disinfect the nest. Indeed, wood ants collect coniferous tree resin, and the presence of resin in their nest protects them against fungal and bacterial pathogens. Many questions remain on the mechanisms of resin use, including which factors elicit resin collection and placement within nests. Here, we investigated whether the presence of brood induces Formica paralugubris workers to collect more resin, and whether the workers preferentially place resin near the brood. We also tested whether the collection and placement of resin depends on the presence of the fungal entomopathogen Beauveria bassiana. Workers brought more resin to their nest when brood was present, and preferentially placed the resin near the brood. In contrast, workers did not increase resin collection in response to exposure to B. bassiana, nor did they place resin closer to contaminated brood or contaminated areas of the nest. This lack of response may be explained by a limited effect of resin against the germination and growth of B. bassiana in vitro. Overall, our main result is that woods ants actively position resin near the brood, which probably confers prophylactic protection against other detrimental microorganisms.

Frequency and Type of Side Effects of Immunomodulating Medication in the Swiss Inflammatory Bowel Disease Cohort

Background: Medical treatment of inflammatory bowel disease (IBD) is becoming more and more complex, as several classes of immuno-modulating drugs (IMD) are often used simultaneously. Thus, the probability of adverse effects is greatly increased. Most studies reporting on adverse effects focus on single therapy, and studies providing a global survey of side effects for multiple treatments are lacking. Aim: To assess the type and frequency of adverse events in IBD patients treated with single and multiple IMD therapy. Methods: Analysis of data from the Swiss IBD Cohort Study (SIBDCS) that collects data on a large sample of IBD patients from hospitals and private practices across Switzerland. The following IMD categories were analyzed: 5-ASA, azathioprine (Aza), 6-mercaptopurine (6-MP), methotrexate (MTX), anti-TNF (infliximab, adalimumab, certolizumab-pegol), cyclosporine, tacrolimus, and steroids. The following side effects were assessed: hepatitis, pancreatitis, leucopenia, thrombopenia, nephritis, allergic reaction, pneumonitis, infections (including tuberculosis), osteoporosis, abdominal pain/diarrhea (unrelated to IBD activity), cataract, diabetes, exanthema, hirsutism, lupus-like syndrome, myalgias, depression/psychosis, tumor development. Results: A total of 1,961 patients were analyzed (977 [50%] female, mean age 42.1 ± 14.4 years): 1,119 with Crohn's disease (CD), 800 with ulcerative colitis (UC), and 42 with indeterminate colitis (IC). Three-hundred eighteen (16.2%) patients were not treated with any of the above-mentioned medications, while 650 (33.2%), 569 (29%) and 424 (21.6%) patients had one-, two-, and three- or more- IMD therapy, respectively. Of the 1,643 patients treated with IMD, 535 (32.6%) patients reported at least one side effect. We found a significant correlation between the number of drugs used by a patient and the frequency of side effects (17.4% side effects for one drug, 29% for 2 drugs, and 60.6% for three or more drugs, p < 0.001). The frequency of side effects for the different IMD classes were as follows: 5-ASA (n = 980 treated patients) 10.8%, Aza/6-MP (n = 636) 51.9% (pancreatitis in 57 = 9%, hepatitis in 17 = 2.7% of treated patients), MTX (n = 146) 42.5% (hepatitis in 4 = 2.7% of treated patients), anti-TNF (n = 255) 23.1%, cyclosporine (n = 49) 10.2%, tacrolimus (n = 5) 20%, steroids (systemic or topical, n = 1,150) 9.6%. Conclusion: IBD treatment is associated with a significant number of side effects. A direct correlation between the number of IMD used simultaneously and the frequency of side effects was observed. The results of this study indicate that treating physicians should be vigilant for the occurrence of side effects in IBD patients under single and/or multiple drug therapy.

Going Public in the European Union: Action Repertoires of Western European Collective Political Actors

As a result of the Europeanization of politics and the increasing role of the public sphere, political actors in Western Europe are currently facing a double strategic challenge. Based on data from seven West European countries and the European Union, the authors analyze how state actors, political parties, interest groups, and social movement organizations cope with this double challenge at both the national and the supranational level. Results indicate that the classic repertoire of inside strategies at the national level is still the most typical for all actors, but media-related strategies are also prominent at the national level. The Europeanization of repertoires is mainly determined by institutional factors and by the actors' power, whereas the public arena plays an equally important role for all types of actors, in all countries and at both the national and the EU level.

Exploring the implementation of a medication adherence programme by community pharmacists : a qualitative study

Background Medication adherence has been identified as an important factor for clinical success. Twenty-four Swiss community pharmacists participated in the implementation of an adherence support programme for patients with hypertension, diabetes mellitus and/or dyslipidemia. The programme combined tailored consultations with patients about medication taking (expected at an average of one intervention per month) and the delivery of each drug in an electronic monitoring system (MEMS6?). Objective To explore pharmacists' perceptions and experiences with implementation of the medication adherence programme and to clarify why only seven patients were enrolled in total. Setting Community pharmacies in French-speaking Switzerland. Method Individual in-depth interviews were audio-recorded, with 20 of the pharmacists who participated in the adherence programme. These were transcribed verbatim, coded and thematically analysed. Process quality was ensured by using an audit trail detailing the development of codes and themes; furthermore, each step in the coding and analysis was verified by a second, experienced qualitative researcher. Main outcome measure Community pharmacists' experiences and perceptions of the determining factors influencing the implementation of the adherence programme. Results Four major barriers were identified: (1) poor communication with patients resulting in insufficient promotion of the programme; (2) insufficient collaboration with physicians; (3) difficulty in integrating the programme into pharmacy organisation; and (4) insufficient pharmacist motivation. This was related to the remuneration perceived as insufficient and to the absence of clear strategic thinking about the pharmacist position in the health care system. One major facilitator of the programme's implementation was pre-existing collaboration with physicians. Conclusion A wide range of barriers was identified. The implementation of medication adherence programmes in Swiss community pharmacies would benefit from an extended training aimed at developing communication and change management skills. Individualised onsite support addressing relevant barriers would also be necessary throughout the implementation process.
