Time to TAVI: streamlining the pathway to treatment.

INTRODUCTION: Severe aortic stenosis is a major cause of morbidity and mortality. The existing treatment pathway for transcatheter aortic valve implantation (TAVI) traditionally relies on tertiary Heart Valve Centre workup. However, this has been associated with delays to treatment, in breach of British Cardiovascular Intervention Society targets. A novel pathway with emphasis on comprehensive patient workup at a local centre, alongside close collaboration with a Heart Valve Centre, may help reduce the time to TAVI. METHODS: The centre performing local workup implemented a novel TAVI referral pathway. Data were collected retrospectively for all outpatients referred for consideration of TAVI to a Heart Valve Centre from November 2020 to November 2021. The main outcome of time to TAVI was calculated as the time from Heart Valve Centre referral to TAVI, or alternative intervention, expressed in days. For the centre performing local workup, referral was defined as the date of multidisciplinary team discussion. For this centre, a total pathway time from echocardiographic diagnosis to TAVI was also evaluated. A secondary outcome of the proportion of referrals proceeding to TAVI at the Heart Valve Centre was analysed. RESULTS: Mean±SD time from referral to TAVI was significantly lower at the centre performing local workup, when compared with centres with traditional referral pathways (32.4±64 to 126±257 days, p<0.00001). The total pathway time from echocardiographic diagnosis to TAVI for the centre performing local workup was 89.9±67.6 days, which was also significantly shorter than referral to TAVI time from all other centres (p<0.003). Centres without local workup had a significantly lower percentage of patients accepted for TAVI (49.5% vs 97.8%, p<0.00001). DISCUSSION: A novel TAVI pathway with emphasis on local workup within a non-surgical centre significantly reduced both the time to TAVI and rejection rates from a Heart Valve Centre. If adopted across the other centres, this approach may help improve access to TAVI.

Implementation of NICE clinical guideline 95 on chest pain of recent onset: experience in a district general hospital.

The National Institute for Health and Care Excellence (NICE) CG95 clinical guideline on chest pain of recent onset was published in 2010. There is debate over whether the proposed strategy improves patient care and its implications on service costs. Following a six-month pilot, 472 consecutive patient records were audited for pre-test probability of significant coronary artery disease, investigations performed and outcomes. Low- and moderate-risk patients had an unexpectedly low rate of coronary disease and revascularisation. Computerised tomography coronary angiography (CTCA) and stress echocardiography performed similarly, though the latter was more resource intensive. High-/very high-risk patients frequently required revascularisation and greater than 10% of each group had prognostically significant disease, going against the recommendation that very high risk patients do not undergo angiography. There were frequent protocol deviations and training clinic staff in the new approach was challenging. In conclusion, implementing NICE CG95 is feasible but presents challenges. Staff require training to follow the protocol consistently. Functional testing had no benefits over anatomical testing with CTCA, which may allow cost savings in some departments.

On the role of positive and negative affectivity in job performance: a meta-analytic investigation.

Although interest regarding the role of dispositional affect in job behaviors has surged in recent years, the true magnitude of affectivity's influence remains unknown. To address this issue, the authors conducted a qualitative and quantitative review of the relationships between positive and negative affectivity (PA and NA, respectively) and various performance dimensions. A series of meta-analyses based on 57 primary studies indicated that PA and NA predicted task performance in the hypothesized directions and that the relationships were strongest for subjectively rated versus objectively rated performance. In addition, PA was related to organizational citizenship behaviors but not withdrawal behaviors, and NA was related to organizational citizenship behaviors, withdrawal behaviors, counterproductive work behaviors, and occupational injury. Mediational analyses revealed that affect operated through different mechanisms in influencing the various performance dimensions. Regression analyses documented that PA and NA uniquely predicted task performance but that extraversion and neuroticism did not, when the four were considered simultaneously. Discussion focuses on the theoretical and practical implications of these findings. (PsycINFO Database Record (c) 2009 APA, all rights reserved).

Policing the social boundaries of the American Medical Association, 1847-70.

In May 1870 the American Medical Association (AMA) voted to deny the admission of black delegates and their white colleagues to the national meeting in Washington, D.C. Historians of race and medicine have customarily viewed this decision as marking a crucial milestone in the formation of the nexus between racism and the development of the American medical profession in the era after the Civil War (1861-64). This study recasts this narrative by locating the 1870 decision in relation to the antebellum practices of the association and their social consequences for American medicine. It argues that the viability of the AMA as the national voice of the profession was critically dependent on rejecting racial equality. Indeed, at a moment when the question of the abolition of slavery polarized the nation, the AMA was founded in 1847 to create a voluntary professional organization, national in scope, dedicated to raising the standards of medical training and practice. To this end, the AMA elected presidents and selected host cities for annual meetings in the North, South, and West. Seven out of the fourteen meetings and six out of fourteen presidents were from slave and/or border states. These institutional practices together with the representation of blacks as different and enjoying an appropriate status as slaves grounded the national identity of the profession in black subordination. Similarly, the gendered discourses about healing and practices of female exclusion privileged medical authority as male by drawing on and reinforcing patriarchy. In the wake of the war, leaders hoped to restore the national character of the organization by resuming antebellum practices. In response to the new possibilities for blacks in medicine--as represented by the biracial National Medical Society--the AMA took steps to vigorously police the racial boundaries of the national profession. As this study will show, the 1870 decision reflected the logic of the racial politics at the heart of the association's antebellum past and would loom large in its future.
