The division of tasks, offshoring and efficiency gains

Die stetige Weiterentwicklung von Informations- und Kommunikationstechnologien (IKT) sowie das Wirtschaftswachstum aufstrebender Länder wie China und Indien haben in den letzten Jahren nicht nur zu einer Intensivierung des internationalen Handels beigetragen. Vielmehr haben sie es Unternehmen erleichtert, ihre Aktivitäten in Länder außerhalb Europas auszulagern. Die Entscheidung der Auslagerung ins Ausland (Offshoring) basiert vor allem auf Kosten-Nutzen-Erwägungen und komparativen Vorteilen. Wirksame politische Maßnahmen erfordern ein tiefgreifendes Verständnis darüber, welche Aktivitäten ausgelagert werden und worin die Stärken der Europäischen Wissensgesellschaft liegen. Vor diesem Hintergrund beschäftigte sich ein vom SEEK-Forschungsprogramm finanziertes Projekt damit, welche Rollen der technologische Wandel und die Globalisierung für die Tätigkeit von Beschäftigten und die Wettbewerbsfähigkeit von Unternehmen einnehmen

Comprehensive self management and routine monitoring in chronic obstructive pulmonary disease patients in general practice: randomised controlled trial

OBJECTIVE To assess the long term effects of two different modes of disease management (comprehensive self management and routine monitoring) on quality of life (primary objective), frequency and patients' management of exacerbations, and self efficacy (secondary objectives) in patients with chronic obstructive pulmonary disease (COPD) in general practice. DESIGN 24 month, multicentre, investigator blinded, three arm, pragmatic, randomised controlled trial. SETTING 15 general practices in the eastern part of the Netherlands. PARTICIPANTS Patients with COPD confirmed by spirometry and treated in general practice. Patients with very severe COPD or treated by a respiratory physician were excluded. INTERVENTIONS A comprehensive self management programme as an adjunct to usual care, consisting of four tailored sessions with ongoing telephone support by a practice nurse; routine monitoring as an adjunct to usual care, consisting of 2-4 structured consultations a year with a practice nurse; or usual care alone (contacts with the general practitioner at the patients' own initiative). OUTCOME MEASURES The primary outcome was the change in COPD specific quality of life at 24 months as measured with the chronic respiratory questionnaire total score. Secondary outcomes were chronic respiratory questionnaire domain scores, frequency and patients' management of exacerbations measured with the Nijmegen telephonic exacerbation assessment system, and self efficacy measured with the COPD self-efficacy scale. RESULTS 165 patients were allocated to self management (n=55), routine monitoring (n=55), or usual care alone (n=55). At 24 months, adjusted treatment differences between the three groups in mean chronic respiratory questionnaire total score were not significant. Secondary outcomes did not differ, except for exacerbation management. Compared with usual care, more exacerbations in the self management group were managed with bronchodilators (odds ratio 2.81, 95% confidence interval 1.16 to 6.82) and with prednisolone, antibiotics, or both (3.98, 1.10 to 15.58). CONCLUSIONS Comprehensive self management or routine monitoring did not show long term benefits in terms of quality of life or self efficacy over usual care alone in COPD patients in general practice. Patients in the self management group seemed to be more capable of appropriately managing exacerbations than did those in the usual care group. TRIAL REGISTRATION Clinical trials NCT00128765.This study was funded by the Netherlands Organisation for Health Research and Development (ZonMw) and Partners in Care Solutions for COPD (PICASSO). The funding sources had no role in the design, conduct, or reporting of the stud

Withdrawal of unnecessary antidepressant medication:a randomised controlled trial in primary care

Background: Antidepressant use has increased exponentially in recent decades, mostly due to long continuation.Aim: To assess the effectiveness of a tailored recommendation to withdraw antidepressant treatment.Design &amp; setting: Randomised controlled trial in primary care (PANDA study) in the Netherlands.Method: Long-term antidepressant users (≥9 months) were selected from GPs prescription databases. Patients were diagnosed with the Composite International Diagnostic Interview (CIDI). Long-term users without indication for maintenance treatment (overtreatment) were selected. The intervention consisted of disclosure of the current psychiatric diagnosis combined with a tailored treatment recommendation. Patients were followed for 12 months.Results: The study included 146 participants from 45 family practices. Of the 70 patients in the intervention group, 34 (49%) did not comply with the advice to stop their antidepressant medication. Of the 36 (51%) patients who agreed to try, only 4 (6%) succeeded. These figures were consistent with the control group, where 6 (8%) of the 76 patients discontinued antidepressant use successfully. Patients who were recommended to discontinue their antidepressant medication reported a higher relapse rate than the control group (26% versus 13%, P = 0.05).Conclusion: Changing inappropriate long-term antidepressant use is difficult.</p

Cape mountain zebra in the Baviaanskloof Nature Reserve, South Africa : resource use reveals limitations to zebra performance in a dystrophic mountainous ecosystem

Resource use of Cape mountain zebra was studied in the Baviaanskloof Nature Reserve (BNR) over concerns of the poor performance in population growth. We assessed the seasonal diet, habitat suitability and forage quality of the Bergplaas area in BNR for mountain zebra. Grasses contributed 95.2 % to the annual diet of mountain zebra, Tristachya leucothrix contributing the most (39.4 %), followed by Themeda triandra (27.6 %). Seasonally, T. triandra contributed most to the diet in winter, while T. leucothrix became more important in the summer and also was the only species preferred in all seasons. Mountain zebra concentrated their feeding in Kouga Grassy Fynbos and from our assessment this was the only habitat suitable for mountain zebra. Our analysis of mountain zebra dung indicated that the seasonal nitrogen and phosphorus content was below the threshold values prescribed for grazers, and our study suggests that mountain zebra at Bergplaas are severely resource limited. We emphasize the importance of fire and access to nutrient-rich lowlands in influencing the nutritional ecology of mountain zebra and provide conservation management recommendations.PRESENCE Learning Networkhttp://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1365-20282016-12-30hb201

Development and psychometric properties of a pain-related problem list for adolescents (PPL)

Instruments for measuring pain-related problems in adolescents with chronic pain are sparse, especially those based on the personal experiences of these adolescents. This study aimed to develop and test such an instrument, the pain-related problem list for adolescents (PPL). A sample of 129 adolescents with chronic pain without documented physiological etiology completed the 57-item problem list, which was based on interviews with a similar group of adolescents with chronic pain. Principal components analysis yielded four domains: problems related to (1) concentration; (2) mobility; (3) adaptability; and (4) mood. The questionnaire was shortened to 18 items and has good reliability (total α = 0.82; concentration α = 0.86; mobility α = 0.77; adaptability α = 0.71; and mood α = 0.78); the validity also proved to be adequate, especially in the general population sample. The PPL provides a tool to assess the impact of chronic pain in adolescents. Future research should focus on further validation of the PPL in a large clinical population and establishing its test-retest reliability

Managing the complexity of doing it all : an exploratory study on students' experiences when trained stepwise in conducting consultations

Background: At most medical schools the components required to conduct a consultation, medical knowledge, communication, clinical reasoning and physical examination skills, are trained separately. Afterwards, all the knowledge and skills students acquired must be integrated into complete consultations, an art that lies at the heart of the medical profession. Inevitably, students experience conducting consultations as complex and challenging. Literature emphasizes the importance of three didactic course principles: moving from partial tasks to whole task learning, diminishing supervisors' support and gradually increasing students' responsibility. This study explores students' experiences of an integrated consultation course using these three didactic principles to support them in this difficult task. Methods: Six focus groups were conducted with 20 pre-clerkship and 19 clerkship students in total. Discussions were audiotaped, transcribed and analysed by Nvivo using the constant comparative strategy within a thematic analysis. Results: Conducting complete consultations motivated students in their learning process as future physician. Initially, students were very much focused on medical problem solving. Completing the whole task of a consultation obligated them to transfer their theoretical medical knowledge into applicable clinical knowledge on the spot. Furthermore, diminishing the support of a supervisor triggered students to reflect on their own actions but contrasted with their increased appreciation of critical feedback. Increasing students' responsibility stimulated their active learning but made some students feel overloaded. These students were anxious to miss patient information or not being able to take the right decisions or to answer patients' questions, which sometimes resulted in evasive coping techniques, such as talking faster to prevent the patient asking questions. Conclusion: The complex task of conducting complete consultations should be implemented early within medical curricula because students need time to organize their medical knowledge into applicable clinical knowledge. An integrated consultation course should comprise a step-by-step teaching strategy with a variety of supervisors' feedback modi, adapted to students' competence. Finally, students should be guided in formulating achievable standards to prevent them from feeling overloaded in practicing complete consultations with simulated or real patients

Polymorphisms in the glucocorticoid receptor gene and in the glucocorticoid-induced transcript 1 gene are associated with disease activity and response to glucocorticoid bridging therapy in rheumatoid arthritis

Glucocorticoids (GC) are widely used in rheumatoid arthritis (RA). Ongoing active disease due to GC resistance may unfavorably influence long-term disease outcome in RA. We studied the association between the presence of glucocorticoid receptor (GR) and glucocorticoid-induced transcript 1 (GLCCI1) gene polymorphisms, which modulate GC sensitivity, and baseline disease activity score (DAS) and efficacy of GC bridging therapy in RA. We prospectively studied in vivo GC sensitivity in 138 patients with recent-onset or longstanding RA. In vivo GC sensitivity was expressed as the relative decrease in DAS following 2 weeks of standardized GC therapy. All patients were genotyped for the GR polymorphisms BclI (rs41423247), N363S (rs6195), 9β (rs6198),

Development and validation of a prognostic multivariable model to predict insufficient clinical response to methotrexate in rheumatoid arthritis

Objective The objective was to predict insufficient response to 3 months methotrexate (MTX) in DMARD naïve rheumatoid arthritis patients. Methods A Multivariable logistic regression model of rheumatoid arthritis patients starting MTX was developed in a derivation cohort with 285 patients starting MTX in a clinical multicentre, stratified single-blinded trial, performed in seven secondary care clinics and a tertiary care clinic. The model was validated in a validation cohort with 102 patients starting MTX at a tertiary care clinic. Outcome was insufficient response (disease activity score (DAS)28 >3.2) after 3 months of MTX treatment. Clinical characteristics, lifestyle variables, genetic and metabolic biomarkers were determined at baseline in both cohorts. These variables were dichotomized and used to construct a multivariable prediction model with backward logistic regression analysis. Results The prediction model for insufficient response in the derivation cohort, included: DAS28>5.1, Health Assessment Questionnaire>0.6, current smoking, BMI>25 kg/m2, ABCB1 rs1045642 genotype, ABCC3 rs4793665 genotype, and erythrocyte-folate<750 nmol/L. In the derivation cohort, AUC of ROC curve was 0.80 (95%CI: 0.73–0.86), and 0.80 (95%CI: 0.69–0.91) in the validation cohort. Betas of the prediction model were transformed into total risk score (range 0–8). At cutoff of 4, probability for insufficient response was 44%. Sensitivity was 71%, specificity 72%, with positive and negative predictive value of 72% and 71%. Conclusions A prognostics prediction model for insufficient response to MTX in 2 prospective RA cohorts by combining genetic, metabolic, clinical and lifestyle variables was developed and validated. This model satisfactorily identified RA patients with high risk of insufficient response to MTX
