Stability in shifting sands: contemporary leadership roles in critical care

Background Contemporary nursing leadership roles in critical care are a reflection of the changing environment in which critical care is provided. Key issues In the UK, critical care nursing faces challenges in the form of: reduced number and seniority of medical staff cover for acute wards; mandated responsibility for management of patients outside of critical care units, without corresponding responsibility for managing staff; increased public and political awareness of deficits in critical care; increased use of Assistant Practitioners; and emphasis on longer‐term outcomes from intensive care. Evaluation New leadership roles have met these challenges head on with two main foci: patient management across the acute/critical care interface and hospital wide policies and practice. Conclusions The leadership roles examined in this paper highlight three underpinning goals: improved quality and safety of patient care; improved communication between professionals; and empowerment of junior nurses and doctors. Implications for nursing management There has been considerable investment in strategic leadership roles for critical care nursing; evidence is developing of the return on this investment for patient and service outcomes. Consideration must now be given to the preparation, mentorship and development of leadership roles for the next generation of nurse leaders.     

The Use of Health Care Policy to Facilitate Evidence-based Knowledge Translation in Emergency Medicine

Health care policy can facilitate emergency medicine knowledge translation (KT). Because of this, the 2007 Academic Emergency Medicine Consensus Conference on KT identified a specific theme regarding issues of health care policy and KT. Six months before the Consensus Conference, international experts in the area were invited to communicate on health care policies regarding all areas of KT via e-mail and "Google groups." From this communication, and using available evidence, specific recommendations and research questions were developed. At the Consensus Conference, additional comments were incorporated. This report summarizes the results of this collaborative effort and provides a set of recommendations and accompanying research questions to guide development, implementation, and evaluation of health care policies intended to promote KT in emergency medicine. The recommendations are to 1a) involve appropriate stakeholders in the health care policy process; 1b) collaborate with policy makers when health care policy focus areas are being developed; 2) use previously validated clinical practice guideline development tools; 3) address implementation issues during the development of health care policies; 4) monitor outcomes with performance measures appropriate to different practice environments; and 5) plan periodic reviews to uncover new clinical evidence, new methods to improve KT, and new technologies. To advance the further development of these recommendations, a research agenda is proposed.     

How can the clinical supervisor role be facilitated in nursing: a phenomenological exploration

Aim  To explore the nature of the nurse clinical supervisor role.
Background  Although clinical supervision in nursing has been widely explored, few studies have considered the specific role of nurse clinical supervisors.
Method  A phenomenological approach was used to explore what it means to be a clinical supervisor. Focus groups interviews were conducted with 12 nurse clinical supervisors within one National Health Service (NHS) Trust.
Results  Three main categories of themes that represented the essence of the clinical supervisors' role were uncovered.
Conclusions  The research demonstrated that nurses who undertake the clinical supervisor role are rarely offered guidelines for fulfilling the role. The findings reveal gaps in the structure of the clinical supervisor's role which could be hampering successful clinical supervision.
Implications for nursing management  The study adds to the existing evidence base and serves to inform managers of the nature of the nurse clinical supervisor role and how it could be better facilitated. The data shed light on the needs of nurse clinical supervisors who often adopt this role in addition to their other clinical and professional commitments. The findings indicate that managerial support in the form of prioritizing training and offering support mechanisms help nurses to effectively fulfil the clinical supervisor role.     

The delay in transfer between the emergency department and the critical care unit for patients with an acute cardiac event — in hospital factors

The Lyell McEwin Health Service (LMHS) is a major public hospital located in the northern suburbs of Adelaide, a region where the death rate from ischaemic heart disease (IHD) is higher than the expected death rate in the population. A retrospective case note study conducted at this hospital investigated the duration that patients with unstable angina pectoris (UA) or acute myocardial infarction (AMI) spent in the emergency department (ED) before admission to the critical care unit (CCU) and the factors that contributed to delays of greater than 70 minutes. All patients admitted to the LMHS over an 18 month period with a discharge diagnosis related group (DRG) for AMI and UA were included in the study. A total of 667 case notes were examined; 403 of these cases met the inclusion criteria for the study.

The mean duration between arrival in the ED and subsequent admission to the CCU was found to be 161 minutes. DRG was a major factor in the length of time spent in the ED. The mean duration for patients with AMI was 124 minutes, whilst for UA the duration was 190 minutes (difference = 66 minutes, p<0.001). Other factors that were signifiant were gender (female = mean duration 29 minutes > males, p=0.015), and mode of transport to the ED (arrival by ambulance mean duration 30 minutes < private transport, p=0.017).

Recommendations arising from this study included that a system be established to enable the rapid assessment of all patients suspected of suffering AMI and UA, inclusive of their expeditious transfer to the CCU. In addition, a staff development programme was proposed to ensure medical and nursing staff become aware of a bias in this hospital toward transferring male patients in a shorter timeframe than females with the same DRG.     

AT1 receptor blockade is superior to conventional triple therapy in protecting against end-organ damage in Cyp1a1-Ren-2 transgenic rats with inducible hypertension

OBJECTIVE: In the present study we compared the effects of treatment with the AT1 receptor antagonist candesartan and of 'triple therapy' (hydralazine, hydrochlorothiazide, reserpine) on the course of blood pressure, cardiac hypertrophy and angiotensin II concentrations after induction of hypertension in transgenic rats with inducible expression of the mouse renin gene (Cyp1a1-Ren-2 rats). METHODS: Hypertension was induced in Cyp1a1-Ren-2 rats through dietary administration of the natural xenobiotic indole-3-carbinol (I3C, 0.3%) for 4 days. Starting on the day before administration of I3C, rats were treated either with candesartan or received triple therapy for 9 days. Systolic blood pressure was measured in conscious animals. Rats were decapitated and angiotensin II levels in plasma and in whole kidney and left ventricular tissues were determined by radioimmunoassay. RESULTS: Administration of I3C resulted in the development of severe hypertension and cardiac hypertrophy that was accompanied by marked elevations of plasma and tissue angiotensin II concentrations. Candesartan treatment prevented the development of hypertension and cardiac hypertrophy and was associated with a reduction of tissue angiotensin II concentrations. In contrast, triple therapy, despite maintaining systolic blood pressure in the normotensive range, did not prevent the development of cardiac hypertrophy and tissue angiotensin II augmentations. CONCLUSIONS: Our findings indicate that hypertension in Cyp1a1-Ren-2 rats is a clearly angiotensin II-dependent model of hypertension with elevated circulating and tissue angiotensin II concentrations, and that antihypertensive treatment with AT1 receptor blockade is superior to conventional triple therapy in effective protection against hypertension-induced end-organ damage in this rat model.     

A Nonrandomised Controlled Trial of Endovenous Laser Therapy and Surgery in the Treatment of Varicose Veins

Endovenous laser therapy (EVLT) is a minimally invasive treatment for varicose veins. This study compares early quality-of-life (QoL) outcomes following EVLT and surgery. Two nonrandomized groups were studied: an EVLT group with 70 patients, median age 49 (interquartile range [IQR] 35-58) years, and a surgery group with 62 patients, median age 49 (IQR 35-61) years. Patients were assessed prior to and at 1, 6, and 12 weeks following the procedure using the Short Form 36 (SF-36), the Aberdeen Varicose Veins Questionnaire (AVVQ), and the Venous Clinical Severity Score (VCSS). Follow-up at 1, 6, and 12 weeks was 100%, 77%, and 70% following EVLT and 100%, 85%, and 47% following surgery. SF-36 scores were significantly better in the EVLT group at 1 week (Physical Functioning, Role Physical, Bodily Pain, Vitality, and Social Functioning domains) and at 6 weeks (Physical Functioning and Role Physical). At 12 weeks, no significant differences were evident between the groups. AVVQ scores were significantly better in the EVLT group at 6 and 12 weeks. VCSS scores were significantly improved in both groups at 12 weeks. EVLT and surgery provide similar QoL improvements in patients with varicose veins. EVLT, however, removes the QoL limitations experienced by patients in the early postoperative period.     

Teachers' experiences of their role following the implementation of Project 2000: a qualitative approach

This study focuses upon the experiences of a group of six nurse teachers who experienced change in their role following the implementation of Project 2000 at their place of work. The teachers were interviewed using the informal interview method which allowed the researcher to obtain detailed information and get to know them as people Qualitative analysis based on a modified grounded theory approach revealed four recurrent themes which were discussed in terms of the context of the study and existing theories The study highlights the feasibility of the grounded theory approach and the informal interviews as a means of collecting detailed data and eliciting in-depth understanding of the participants' experience of their changed role from their perspective The informal interviews and the researcher's knowledge of the participants and the context in which the study was conducted have proved to be helpful in generating categories which describe the teachers' experiences of the changes in their role
