Meanings and perceptions of patient-centeredness in social work, nursing and medicine: A comparative study.

Answering patients' evolving, more complex needs has been recognized as a main incentive for the development of interprofessional care. Thus, it is not surprising that patient-centered practice (PCP) has been adopted as a major outcome for interprofessional education. Nevertheless, little research has focused on how PCP is perceived across the professions. This study aimed to address this issue by adopting a phenomenological approach and interviewing three groups of professionals: social workers (n = 10), nurses (n = 10) and physicians (n = 8). All the participants worked in the same department (the General Internal Medicine department of a university affiliated hospital). Although the participants agreed on a core meaning of PCP as identifying, understanding and answering patients' needs, they used many dimensions to define PCP. Overall, the participants expressed value for PCP as a philosophy of care, but there was the sense of a hierarchy of patient-centeredness across the professions, in which both social work and nursing regarded themselves as more patient-centered than others. On their side, physicians seemed inclined to accept their lower position in this hierarchy. Gieryn's concept of boundary work is employed to help illuminate the nature of PCP within an interprofessional context.

Evaluation of performance analysis software for Linux computing cluster

Tietokonejärjestelmän osien ja ohjelmistojen suorituskykymittauksista saadaan tietoa,jota voidaan käyttää suorituskyvyn parantamiseen ja laitteistohankintojen päätöksen tukena. Tässä työssä tutustutaan suorituskyvyn mittaamiseen ja mittausohjelmiin eli ns. benchmark-ohjelmistoihin. Työssä etsittiin ja arvioitiin eri tyyppisiä vapaasti saatavilla olevia benchmark-ohjelmia, jotka soveltuvat Linux-laskentaklusterin suorituskyvynanalysointiin. Benchmarkit ryhmiteltiin ja arvioitiin testaamalla niiden ominaisuuksia Linux-klusterissa. Työssä käsitellään myös mittausten tekemisen ja rinnakkaislaskennan haasteita. Benchmarkkeja löytyi moneen tarkoitukseen ja ne osoittautuivat laadultaan ja laajuudeltaan vaihteleviksi. Niitä on myös koottu ohjelmistopaketeiksi, jotta laitteiston suorituskyvystä saisi laajemman kuvan kuin mitä yhdellä ohjelmalla on mahdollista saada. Olennaista on ymmärtää nopeus, jolla dataa saadaan siirretyä prosessorille keskusmuistista, levyjärjestelmistä ja toisista laskentasolmuista. Tyypillinen benchmark-ohjelma sisältää paljon laskentaa tarvitsevan matemaattisen algoritmin, jota käytetään tieteellisissä ohjelmistoissa. Benchmarkista riippuen tulosten ymmärtäminen ja hyödyntäminen voi olla haasteellista.

Coping with an HIV infection. A multicenter qualitative survey on HIV positive adolescents' perceptions of their disease, therapeutic adherence and treatment.

HIV-positive adolescents face a number of challenges in dealing with their disease and its treatment. In this qualitative study, twenty-nine HIV-positive adolescents aged 13 to 20 years (22 girls), who live in Switzerland, were asked, in a semi-structured interview (duration of 40-110 minutes), to describe their perceptions and experiences with the disease itself and with therapeutic adherence. While younger adolescents most often thought of their disease as fate, older adolescents usually knew that they had received it through vertical transmission, although the topic appeared to be particularly difficult to discuss for those living with their HIV-positive mothers. Based on their attending physician's assessment, 18 subjects were judged highly adherent, 4 fairly and 7 poorly adherent. High adherence appeared linked with adequate psychological adjustment and effective coping mechanisms, as well as with the discussion and adoption of explicit medication-taking strategies. The setting and organisation of health care teams should allow for ongoing discussions with HIV-positive adolescents that focus on their perceptions of their disease, how they cope with it and with the treatment, and how they could improve their adherence.

Effect of water velocity on the uptake of polychlorinatedd biphenyls (PCBs) by silicone rubber (SR) and low-density polyethylene (LDPE) passive samplers: an assessment of the efficiency of performance reference compounds (PRCs) in river-like flow conditions

One aim of this study is to determine the impact of water velocity on the uptake of indicator polychlorinated biphenyls (iPCBs) by silicone rubber (SR) and low-density polyethylene (LDPE) passive samplers. A second aim is to assess the efficiency of performance reference compounds (PRCs) to correct for the impact of water velocity. SR and LDPE samplers were spiked with 11 or 12 PRCs and exposed for 6 weeks to four different velocities (in the range of 1.6 to 37.7 cm s−1) in river-like flow conditions using a channel system supplied with river water. A relationship between velocity and the uptakewas found for each iPCB and enables to determine expected changes in the uptake due to velocity variations. For both samplers, velocity increases from 2 to 10 cm s−1, 30 cm s−1 (interpolated data) and 100 cm s−1 (extrapolated data) lead to increases of the uptake which do not exceed a factor of 2, 3 and 4.5, respectively. Results also showed that the influence of velocity decreased with increasing the octanol-water coefficient partition (log Kow) of iPCBs when SR is used whereas the opposite effect was observed for LDPE. Time-weighted average (TWA) concentrations of iPCBs in water were calculated from iPCB uptake and PRC release. These calculations were performed using either a single PRC or all the PRCs. The efficiency of PRCs to correct the impact of velocity was assessed by comparing the TWA concentrations obtained at the four tested velocities. For SR, a good agreement was found among the four TWA concentrations with both methods (average RSD b 10%). Also for LDPE, PRCs offered a good correction of the impact of water velocity (average RSD of about 10 to 20%). These results contribute to the process of acceptance of passive sampling in routine regulatory monitoring programs.

Perceptions of twelve-step mutual-help groups and their associations with motivation, treatment attendance and alcohol outcomes among chronically homeless individuals with alcohol problems.

BACKGROUND: Twelve-step mutual-help groups (TMGs) are among the most available forms of support for homeless individuals with alcohol problems. Qualitative research, however, has suggested that this population often has negative perceptions of these groups, which has been shown to be associated with low TMG attendance. It is important to understand this population's perceptions of TMGs and their association with alcohol outcomes to provide more appropriate and better tailored programming for this multiply affected population. The aims of this cross-sectional study were to (a) qualitatively examine perception of TMGs in this population and (b) quantitatively evaluate its association with motivation, treatment attendance and alcohol outcomes. METHODS: Participants (N=62) were chronically homeless individuals with alcohol problems who received single-site Housing First within a larger evaluation study. Perceptions of TMGs were captured using an open-ended item. Quantitative outcome variables were created from assessments of motivation, treatment attendance and alcohol outcomes. RESULTS: Findings indicated that perceptions of TMGs were primarily negative followed by positive and neutral perceptions, respectively. There were significant, positive associations between perceptions of TMGs and motivation and treatment attendance, whereas no association was found for alcohol outcomes. CONCLUSIONS: Although some individuals view TMGs positively, alternative forms of help are needed to engage the majority of chronically homeless individuals with alcohol problems.

Time patterns and perceptions of online learning success factors

Online learning provides the opportunity to work on academic tasks at any time at the same time as doing other activities, such as using in web 2.0 tools. This study identifies factors that contribute to success in online learning from the students¿ perspective and their relationship with time patterns. A survey of learning outputs was used to find relationships between students¿ satisfaction, knowledge acquisition and knowledge transfer with time for working on academic tasks. In this study, 199 students from a university in Mexico completed the survey. Findings suggest that knowledge transfer has a significant association with the number of hours online per day, hours spent on social networks and the use made of e-learning during working hours. Learner satisfaction has a strong relationship with the time in years a learner has been using the Internet and the number of hours devoted to the course per week. The findings of this research will be helpful for faculty and instructional designers for implementing learning strategies.

The Impact of Catechol-O-Methyltransferase and Dopamine D4 Receptor Genotypes on Neurophysiological Markers of Performance Monitoring

Dynamic adaptations of one"s behavior by means of performance monitoring are a central function of the human executive system, that underlies considerable interindividual variation. Converging evidence from electrophysiological and neuroimaging studies in both animals and humans hints atthe importance ofthe dopaminergic system forthe regulation of performance monitoring. Here, we studied the impact of two polymorphisms affecting dopaminergic functioning in the prefrontal cortex [catechol-O-methyltransferase (COMT) Val108/158Met and dopamine D4 receptor (DRD4) single-nucleotide polymorphism (SNP)-521] on neurophysiological correlates of performance monitoring. We applied a modified version of a standard flanker task with an embedded stop-signal task to tap into the different functions involved, particularly error monitoring, conflict detection and inhibitory processes. Participants homozygous for the DRD4 T allele produced an increased error-related negativity after both choice errors and failed inhibitions compared with C-homozygotes. This was associated with pronounced compensatory behavior reflected in higher post-error slowing. No group differences were seen in the incompatibility N2, suggesting distinct effects of the DRD4 polymorphism on error monitoring processes. Additionally, participants homozygous for the COMTVal allele, with a thereby diminished prefrontal dopaminergic level, revealed increased prefrontal processing related to inhibitory functions, reflected in the enhanced stop-signal-related components N2 and P3a. The results extend previous findings from mainly behavioral and neuroimaging data on the relationship between dopaminergic genes and executive functions and present possible underlying mechanisms for the previously suggested association between these dopaminergic polymorphisms and psychiatric disorders as schizophrenia or attention deficit hyperactivity disorder.

Older persons' perceptions of general practitioner or specialist primary care physicians : same point of view? : older persons' primary care perception

La perception du patient vis-à-vis de son médecin traitant (MT) a suscité beaucoup de recherches et d'interet, notamment à cause de l'importance de la relation médecin-patient nécessaire à la qualité des soins. En Suisse, dans un contexte de libre choix du médecin, le rôle de MT peut être assumé par un generalise mais aussi, théoriquement, par un spécialiste. La fréquence de cette situation est cependant inconnue de même que son impact sur l'expérience des patients. L'objectif principal de cette etude était de décrire l'expérience des personnes âgées du canton de Vaud auprès de leur medecin traitant et de tester l'hypothèse selon laquelle cette expérience serait différente lorsque le MT est décrit comme « Généraliste » (MT Gén) ou comme « Spécialiste » (MT Spéc). Méthode : La recherche a été effectuée sur la base des données d'une enquête par questionnaire, envoyé à la population lausannoise participant à l'étude Lc65+ et à un échantillon supplémentaire de personnes agees de 68 ans ou plus sélectionnées aléatoirement dans le canton de Vaud. L'analyse a porté sur 17 items relatifs à la perception qu'ont les patients de leur MT, regroupés en 4 thèmes ? Access,bihte/Disponibilité, Relation Médecin-Patient, Information et Continuité des soins Nous ayons également analysé le recours déclaré aux soins ambulatoires, aux consultations de services d urgence, ainsi qu'aux actes de prévention. Les différences de perception et de recours selon le type de MT (Gen vs Spéc) ont été analysées par des modèles multivariés tenant compte de l'âge du sexe de I education, de la morbidité, de la présence de symptômes dépressifs et de la durée de la relation medecin-patient. Résultats : Les participants ont exprimé une perception favorable de leur MT à des taux excédant 75% pour la plupart des 17 items. Cependant, seulement 38 à 51% des participants ont répondu positivement aux questions relatives à la disponibilité en dehors des heures d'ouvertures, à l'accès au MT le soir ou en tin de semaine, à la possibilité de visites à domicile, à la probabilité de se voir prescrire des medicaments coûteux en cas de besoin, ou à la connaissance du médecin des médicaments en vente libre que le patient consomme. Les analyses bivariées et multivariées n'ont pas montré de différence entre les groupes MT Gén et MT Spec quant à la perception qu'ont les patients de leur MT, au recours aux actes de prévention ou aux services de santé. Conclusion : L'expérience des personnes interrogées était globalement positive, à part quelques questions concernant principalement le thème de l'Accessibilité/Disponibilité du MT. Nous n'avons pas mis en evidence de différence de perception ou de recours aux soins entre les deux groupes que nous avons analyses pour tester notre hypothèse. Perspective : Cette étude connaît des limites (données rapportées par les participants, groupe des MT Spéc de taille restreinte, absence de données sur les non-répondants, possible conflit de loyauté vis-à-vis du MT pour certaines questions) mais repose sur un large échantillon lui conférant une puissance suffisante, aléatoirement sélectionné dans une population géographiquement définie. Bien que ces résultats ne soient généralisables qu'au canton de Vaud, elle montre d'abord que les spécialistes reconnus comme MT s'inscrivent généralement dans des disciplines impliquant une formation en medec.ne interne. Dans cette circonstance, elle ne met en évidence aucune différence de résultats entre les personnes âgées traitées par un MT généraliste ou spécialiste.

Perceptions of Alzheimer's Disease in the French Population : Evolutions between 2008 and 2013 and Associated Factors in 2013

Abstract: Background. The negative image surrounding AD has a substantial impact on caregiving and on those affected by the disease. Opinion surveys was created as part of the 2008-2012 Alzheimer Plan in France, which included two surveys in general population, at the beginning and at the end. Objective. To evaluate changes of the French population in perceptions, knowledge and beliefs since 5 years and to analyze dimensions with sociodemographics criteria and proximity with AD. Methods. After selection by quota sampling, 2013 French people aged 18 years and over were interviewed by phone in 2008 and 2509 in 2013. Chi-squared tests were carried out to measure the changes between two periods and multivariate logistics regressions were used to assess perceptions. Results. People who cited AD as one of the three most serious diseases increased in 2013 (33.6% versus 26.7% in 2008; p < 0.001). There was no significant change as regards the fear, the sense of being informed and the feeling of embarrassment. Opinions "there are treatments available to improve the wellbeing of patients" and "it is normal to suffer memory loss as you get older" decreased in 2013. Close family carers had a greater sense of the seriousness, a higher risk perception, a better sense of being informed and a greater ease in the presence of a person with AD. Conclusions. The results serve as indicators of the effects of the Alzheimer Plan on French society and testify to the rather weak impact of the Plan on public opinion.
