Since this would jeopardize the long-term function of the access, the area was revised by interposing a short segm ent of PTFE to a new venous outflow adjacent to the aneurysm al segm ent.

The lateral area of the loop was initially replaced, and when this was healed C and functioning well the m edial segm ent was replaced. Vascular steal is a com m on problem of dialysis access sites. The principle of steal is related to two phenom ena: 1) calcification or stenosis in the inflow arterial seg- m ent proxim al to an access site (so that the native artery cannot dilate to m eet the increas- ing demands for flow volume); 2) and an outflow arterial bed in parallel to the fistula origin with higher net vascular resistance than the fistula conduit. If both of these are present, blood flow is diverted to the access site in association with a drop in perfusion pressure to the m ost acral tissues, the fingers. W hen steal is severe, traum a to the digits leads to gan- grene. Several treatm ent strategies are available to the surgeon. The access can be “band- ed,” or purposefully stenosed at its origin to divert flow to the ischem ic site. The access can be revised using a tapered graft or the point of origin of the access can be m oved m ore proxim ally in the arterial tree, in the hope of allowing full flow without diverting distal perfusion pressure. Additionally, one can perform a variety of bypass procedures to divert higher-pressure proxim al blood to increase distal perfusion pressure. In severe cases, either the access or the distal digits m ay be sacrificed to preserve the other. M easurem ent of graft blood flow (using Doppler im aging, ultra- sound dilution, or another m ethod) is increasingly available and m ay be the best screening m ethod. W hen graft flow declines below dialyzer blood flow (E), blood flows between the needles (F) in a retrograde direction. This developm ent is called recirculation, since it results in repeated uptake and dialysis of blood that has just been dialyzed. Recirculation can be detected by finding evidence that blood from the venous cannula is being taken up by the arterial cannula. This is m ost often recognized by the finding of an arterial blood urea nitrogen value below that in blood entering the graft. A stenotic lesion in an outflow vein tends to increase the pressure in the vein and graft (G ) between the stenosis and the venous nee- dle. This pressure usually ranges from 25 to 50 m m H g but m ay increase to m ore than 70 m m H g in the presence of stenosis. This pressure can be m easured directly or can be estim ated from the venous pressure m onitor on the dialysis m achine at zero blood FIGURE 5-18 flow (adjusting for the difference in height between the graft and Vascular access screening m ethods.

It involves experimentation discount fildena 25mg on line impotence thesaurus, iteration and trialling rather than linear implementation of a top-down strategy. Storey and Holti53 found that NHS structures and culture often present numerous barriers to the effectiveness of clinical leadership for improving service co-ordination and integration from within the acute sector. Despite the barriers, they also found cases where determined doctors and other clinicians persisted in their attempts to exert positive influence on reshaping service design and delivery.

INTRODUCTION As the above analysis indicates, there is considerable overlap between the issues researched as part of understanding leadership in health and the related domain of understanding service redesign and change in health. It is towards this last domain that we now turn our attention. Service redesign of health and social care Most reports of actual attempts to bring about transformative change in health care have tended to focus on the acute sector. As largely hierarchical organisations these settings have lent themselves to exploration of redesign methods derived from the business literature including, for example, business 59–63 process re-engineering. The analysis of attempts to introduce radical redesign of processes in acute hospitals reveals the complexity of such attempts and the micro-political struggles involved. It is not only clinicians who engage in institutional work when creating new forms or shoring up old ones, managers in health service redesign attempts are also heavily involved. The findings from research in the acute health-care setting reflect findings and theory from the wider organisational theory literature. Institutional work is found in everyday activities, which can be seen to serve underlying purposes. We build on the institutional work perspective in our case studies. It is important to note that attempts at exercising clinical leadership are located within existing institutional arrangements. Within the context of the NHS, a great deal of institution shaping and reshaping emanates from higher-level actors, most notably NHSE and political agents; these set the direction of travel and allocate resources (financial- and legitimacy-based resources). The very origins of CCGs themselves stemmed from this source, followed by the Five Year Forward View12 and the STPs. Each of these institutional shifts was built on the assumption of the need to relocate care from hospitals to community settings. During this journey there was a move from a reliance on commissioning in a competitive market environment to large-scale planning and collaboration. Recent literature has begun to question the validity of assumptions about savings and efficiency in the shift to community care. Our research was directed at these forms of leadership. In CCGs, as with many other membership bodies, it evidently often proves difficult to fully engage the wider membership in any meaningful way. There remains a significant gap between the ambitious agendas for change set out in key policy papers and the reality on the ground of actions taken, to date, by most CCGs. Key themes emerging as requiring deeper understanding include: l the forms of influence that clinicians are actually achieving both as commissioners and providers under CCGs and associated arrangements l how leaders (managers and clinicians) are able to use the CCG as a platform and resource to bring about service redesign and, as a key part of this, the balance between formal and informal opportunities for leadership l the impact of these emerging forms of power and influence on the achievement of more integrated and effective forms of patient care.

The project proceeded through a series of sequential steps in five phases as mapped in the project Gantt chart (see Appendix 1). An extended scoping study encompassing 15 CCGs spread across England. Drawing on the results of this scoping work and on a review of the relevant literature, a national survey was designed and administered with the target population being all members of the governing boards of all 210 CCGs. This work was designed to reveal details of the processes involved in seeking meaningful service redesign through the deployment of clinical leadership and the in-depth study of a number of specific examples of attempted service redesign within these cases; the method here was to study clinical leadership in action. Drawing on the lessons learned from the case study work in phase 3, a second national survey was designed.
