Clinical implications of the Royal College of Physicians three questions in routine asthma care: A real-life validation study
BACKGROUND: Annual recording of the Royal College of Physicians three questions (RCP3Q) morbidity score is rewarded within the UK 'pay-for-performance' Quality and Outcomes Framework. AIMS: To investigate the performance of the RCP3Qs for assessing control in real-life practice compared with the validated Asthma Control Questionnaire (ACQ) administered by self-completed questionnaire. METHODS: We compared the RCP3Q score extracted from a patient's computerised medical record with the ACQ self-completed after the consultation. The anonymous data were paired by practice, age, sex, and dates of completion. We calculated the sensitivity and specificity of the RCP3Q scale compared with the threshold for good/poor asthma control (ACQ greater than 1). RESULTS: Of 291 ACQ questionnaires returned from 12 participating practices, 129 could be paired with complete RCP3Q data. Twenty-five of 27 patients who scored zero on the RCP3Q were well controlled (ACQ less than 1). An RCP3Q score greater than 1 predicted inadequate control (ACQ greater than 1) with a sensitivity of 0.96 and specificity of 0.34. Comparable values for RCP3Q greater than 2 were sensitivity 0.50 and specificity 0.94. The intraclass correlation coefficient of 0.13 indicated substantial variability between practices. Exacerbations and use of reliever inhalers were moderately correlated with ACQ (Spearman's rho 0.3 and 0.35) and may reflect different aspects of control. CONCLUSIONS: In routine practice, an RCP3Q score of zero indicates good asthma control and a score of 2 or 3 indicates poor control. An RCP3Q score of 1 has good sensitivity but poor specificity for suboptimal control and should provoke further enquiry and consideration of other aspects of control such as exacerbations and use of reliever inhalers
Reconsidering the aid relationship: International relations and social development
Recent rhetoric surrounding the contemporary aid relationship between donors and African states is couched in terms of a high level consensus between western and African political leaderships, a central pillar of which is adherence to liberal principles of governance and economic management. The paper argues that an analysis of the nature of this consensus and its prospects requires that we need to understand it as (i) encompassing specifically international-geopolitical dimensions (including state interests, bargaining and power); and (ii) social-developmental purposes and content. The paper uses Rosenberg's considerations on 'international sociology' and uneven and combined development to provide a framework for analysing the aid relationship. In doing this, the paper speaks to two related theoretical issues: conceptualisations of the relationship between the 'social developmental' and the 'geopolitical/international' within International Relations (IR); and the contemporary relevance or otherwise of the discipline of IR to analyses of Africa's place in the international system
Novel study design to assess the utility of the copd assessment test in a primary care setting
The quality of a consultation provided by a physician can have a profound impact on the quality of care and
patient engagement in treatment decisions. When the COPD Assessment Test (CAT) was developed, one of its aims
was to aid the communication between physician and patient about the impact of COPD. We developed a novel
study design to assess this in a primary care consultation.
Primary care physicians across five countries in Europe conducted videoed consultations with six standardised
COPD patients (played by trained actors) which had patient-specific issues that the physician needed to identify
through questioning. Half the physicians saw the patients with the completed CAT, and half without. Independent
assessors scored the physicians on their ability to identify and address the patient-specific issues, review standard COPD aspects, their understanding of the case and their overall performance. This novel study design presented
many challenges which needed to be addressed to achieve an acceptable level of robustness to assess the utility of
the CAT. This paper discusses these challenges and the measures adopted to eliminate or minimise their impact on
the study results
Targeting a Newly Established Spontaneous Feline Fibrosarcoma Cell Line by Gene Transfer
Fibrosarcoma is a deadly disease in cats and is significantly more often located at classical vaccine injections sites. More rare forms of spontaneous non-vaccination site (NSV) fibrosarcomas have been described and have been found associated to genetic alterations. Purpose of this study was to compare the efficacy of adenoviral gene transfer in NVS fibrosarcoma. We isolated and characterized a NVS fibrosarcoma cell line (Cocca-6A) from a spontaneous fibrosarcoma that occurred in a domestic calico cat. The feline cells were karyotyped and their chromosome number was counted using a Giemsa staining. Adenoviral gene transfer was verified by western blot analysis. Flow cytometry assay and Annexin-V were used to study cell-cycle changes and cell death of transduced cells. Cocca-6A fibrosarcoma cells were morphologically and cytogenetically characterized. Giemsa block staining of metaphase spreads of the Cocca-6A cells showed deletion of one of the E1 chromosomes, where feline p53 maps. Semi-quantitative PCR demonstrated reduction of p53 genomic DNA in the Cocca-6A cells. Adenoviral gene transfer determined a remarkable effect on the viability and growth of the Cocca-6A cells following single transduction with adenoviruses carrying Mda-7/IL-24 or IFN-γ or various combination of RB/p105, Ras-DN, IFN-γ, and Mda-7 gene transfer. Therapy for feline fibrosarcomas is often insufficient for long lasting tumor eradication. More gene transfer studies should be conducted in order to understand if these viral vectors could be applicable regardless the origin (spontaneous vs. vaccine induced) of feline fibrosarcomas
Citizens and Condemnation: Strategic Uses of International Human Rights Pressure in Authoritarian States
Governments with strict control over the information that their citizens hear from foreign sources are regular targets of human rights pressure, but we know little about how this information matters in the domestic realm. I argue that authoritarian regimes strategically pass on certain types of external pressure to their public to “internationalize” human rights violations, making citizens view human rights in terms of defending their nation internationally rather than in terms of individual violations, and making them more likely to be satisfied with their government’s behavior. I find strong support for this model through statistical analysis of Chinese state media reports of external human rights pressure and a survey experiment on Chinese citizens’ responses to pressure on women’s rights. This analysis demonstrates that authoritarian regimes may be able to manipulate international human rights diplomacy to help them retain the support of their population while suppressing their human rights
Can asthma control be improved by understanding the patient's perspective?
Clinical trials show that asthma can be controlled in the majority of patients, but poorly controlled asthma still imposes a considerable burden. The level of asthma control achieved reflects the behaviour of both healthcare professionals and patients. A key challenge for healthcare professionals is to help patients to engage in self-management behaviours with optimal adherence to appropriate treatment. These issues are particularly relevant in primary care, where most asthma is managed. An international panel of experts invited by the International Primary Care Respiratory Group considered the evidence and discussed the implications for primary care practice
Systematic meta-review of supported self-management for asthma: a healthcare perspective
BACKGROUND: Supported self-management has been recommended by asthma guidelines for three decades; improving current suboptimal implementation will require commitment from professionals, patients and healthcare organisations. The Practical Systematic Review of Self-Management Support (PRISMS) meta-review and Reducing Care Utilisation through Self-management Interventions (RECURSIVE) health economic review were commissioned to provide a systematic overview of supported self-management to inform implementation. We sought to investigate if supported asthma self-management reduces use of healthcare resources and improves asthma control; for which target groups it works; and which components and contextual factors contribute to effectiveness. Finally, we investigated the costs to healthcare services of providing supported self-management.
METHODS: We undertook a meta-review (systematic overview) of systematic reviews updated with randomised controlled trials (RCTs) published since the review search dates, and health economic meta-analysis of RCTs. Twelve electronic databases were searched in 2012 (updated in 2015; pre-publication update January 2017) for systematic reviews reporting RCTs (and update RCTs) evaluating supported asthma self-management. We assessed the quality of included studies and undertook a meta-analysis and narrative synthesis.
RESULTS: A total of 27 systematic reviews (n = 244 RCTs) and 13 update RCTs revealed that supported self-management can reduce hospitalisations, accident and emergency attendances and unscheduled consultations, and improve markers of control and quality of life for people with asthma across a range of cultural, demographic and healthcare settings. Core components are patient education, provision of an action plan and regular professional review. Self-management is most effective when delivered in the context of proactive long-term condition management. The total cost (n = 24 RCTs) of providing self-management support is offset by a reduction in hospitalisations and accident and emergency visits (standard mean difference 0.13, 95% confidence interval -0.09 to 0.34).
CONCLUSIONS: Evidence from a total of 270 RCTs confirms that supported self-management for asthma can reduce unscheduled care and improve asthma control, can be delivered effectively for diverse demographic and cultural groups, is applicable in a broad range of clinical settings, and does not significantly increase total healthcare costs. Informed by this comprehensive synthesis of the literature, clinicians, patient-interest groups, policy-makers and providers of healthcare services should prioritise provision of supported self-management for people with asthma as a core component of routine care.
