Applying the National Institute for Clinical Excellence criteria to patients treated with the Genous (TM) Bio-engineered R stent (TM): a sub-study of the e-HEALING (Healthy Endothelial Accelerated Lining Inhibits Neointimal Growth) worldwide registry

The National Institute for Clinical Excellence (NICE) guidelines recommend the use of bare-metal stents (BMS) in non-complex lesions with a low risk of restenosis (diameter a parts per thousand yen3 mm and lesion length a parts per thousand currency sign15 mm) and the use of drug-eluting stents (DES) in more complex lesions with a high risk of restenosis (diameter < 3.0 mm or lesion length > 15 mm). However, the guidelines were created based on studies evaluating BMS and DES only. We performed an analysis of patients undergoing non-urgent percutaneous coronary intervention with the novel endothelial cell capturing stent (ECS). The ECS is coated with CD34(+) antibodies that attract circulating endothelial progenitor cells to the stent surface, thereby accelerating the endothelialization of the stented area. We analyzed all patients enrolled in the worldwide e-HEALING registry that met the NICE criteria for either low-risk or high-risk lesions and were treated with a parts per thousand yen1 ECS. The main study outcome was target vessel failure (TVF) at 12-month follow-up, defined as the composite of cardiac death or MI and target vessel revascularization (TVR). A total of 4,241 patients were assessed in the current analysis. At 12-month follow-up, TVF occurred in 7.0% of the patients with low-risk lesions and in 8.8% of the patients with high-risk lesions (p = 0.045). When evaluating the diabetic patients versus the non-diabetic patients per risk group, no significant differences were found in TVF, MI or TVR in either risk group. The ECS shows good clinical outcomes in lesions carrying either a high or a low risk of restenosis according to the NICE guidelines with comparable rates of cardiac death, myocardial infarction, and stent thrombosis. The TVF rate with ECS was slightly higher in patients with high-risk lesions, driven by higher clinically driven TLR. The risk of restenosis with ECS in patients carrying high-risk lesions needs to be carefully considered relative to other risks associated with DES. Furthermore, the presence of diabetes mellitus did not influence the incidence of TVF in either risk group.

National Institute for Clinical Studies Report for Phase 1, Evidence Uptake Network : Best Practice Community Care for Clients with Chronic Venous Leg Ulcers

Chronic leg ulcers cause significant pain, cost, decreased quality of life and morbidity for a considerable segment of the older population (Graham et al., 2003a). At any given time the prevalence of patients with open leg ulcers receiving treatment is between 0.11% - 0.18% (Briggs & Closs 2003). Chronic leg ulcers occur in approximately 1 - 2% of the over 60 population in the US, UK, Europe and Australia (Baker & Stacey 1994; Johnson 1995; Lees & Lambert 1992; Margolis et al. 2002). Considerable research has been undertaken to determine the best treatment practices that will aid in the management and the healing of these ulcers, and practical and effective strategies and techniques for healing venous leg ulcers have been trialled to demonstrate their beneficial effects (Nelson et al. 2004; Cullum et al. 2001)...

Attitudes of consultant ophthalmologists in the UK to initial management of glaucoma patients presenting with severe visual field loss: a national survey

BACKGROUND: Recent National Institute of Clinical Excellence guidance suggests primary surgery should be offered to patients presenting with glaucoma with severe visual field loss. We undertook a survey of UK consultant ophthalmologists to determine if this represents current practice and explore attitudes towards managing patients with advanced glaucoma at presentation.

DESIGN: Questionnaire evaluation study.

PARTICIPANTS: All consultant ophthalmologists currently practicing in the UK.

METHODS: A single-page questionnaire was posted to all consultants (n = 910) currently practicing in the UK along with a pre-paid return envelope. A second questionnaire was sent to non-responders (n = 459).

MAIN OUTCOME MEASURES: Questionnaire responses.

RESULTS: 626 responses were received representing 68.8% of the population surveyed. 152 (24%) volunteered a specialist interest in glaucoma. Consensus opinion for both glaucoma specialists (64.9%) and non-glaucoma specialists (62.4%) was to start with primary medical therapy, most commonly citing surgical risk as the primary reason (23% and 22%, respectively) for this approach. Most felt the highest intraocular pressure measurement during follow up (measured in clinic) was the most important variable for prevention of further visual loss (60% of glaucoma specialists and 55% of non-glaucoma specialists). Eighty-three per cent of all responders suggested they would change their practice if evidence supporting primary surgery as a safe and more effective approach existed.

CONCLUSIONS: Recent National Institute of Clinical Excellence guidance does not reflect the current management approach of UK ophthalmologists. The primary concern was related to potential complications of surgery although most practitioners would be willing to change their practice if evidence existed supporting primary surgery in patients presenting with advanced glaucoma.

Prevention of surgical site infection in total joint arthroplasty : an international tertiary care center survery

Background Prevention strategies are critical to reduce infection rates in total joint arthroplasty (TJA), but evidence-based consensus guidelines on prevention of surgical site infection (SSI) remain heterogeneous and do not necessarily represent this particular patient population. Questions/Purposes What infection prevention measures are recommended by consensus evidence-based guidelines for prevention of periprosthetic joint infection? How do these recommendations compare to expert consensus on infection prevention strategies from orthopedic surgeons from the largest international tertiary referral centers for TJA? Patients and Methods A review of consensus guidelines was undertaken as described by Merollini et al. Four clinical guidelines met inclusion criteria: Centers for Disease Control and Prevention's, British Orthopedic Association, National Institute of Clinical Excellence's, and National Health and Medical Research Council's (NHMRC). Twenty-eight recommendations from these guidelines were used to create an evidence-based survey of infection prevention strategies that was administered to 28 orthopedic surgeons from members of the International Society of Orthopedic Centers. The results between existing consensus guidelines and expert opinion were then compared. Results Recommended strategies in the guidelines such as prophylactic antibiotics, preoperative skin preparation of patients and staff, and sterile surgical attire were considered critically or significantly important by the surveyed surgeons. Additional strategies such as ultraclean air/laminar flow, antibiotic cement, wound irrigation, and preoperative blood glucose control were also considered highly important by surveyed surgeons, but were not recommended or not uniformly addressed in existing guidelines on SSI prevention. Conclusion Current evidence-based guidelines are incomplete and evidence should be updated specifically to address patient needs undergoing TJA.

Bereavement Assessment Practice in Hospice Settings: Challenges for Palliative Care Social Workers

The management and delivery of bereavement support services in palliative care settings presents practical and ethical challenges. A national survey, conducted in 2007, examined bereavement practice in ten Marie Curie hospices across the United Kingdom. This qualitative study was undertaken using semi-structured telephone interviews with Bereavement Service Leaders located in each hospice. Although findings revealed that bereavement services were in operation and had been reviewed in response to the National Institute for Clinical Excellence Guidance (2004), and all bereaved families were offered support, there was no standardisation of service delivery across sites. Multi-disciplinary team meetings facilitated shared decision-making for bereavement follow-up, and expanded and clarified documentation completed by nursing staff around the time of the patient’s death. However, there was ambiguity regarding professional ‘duty of care’ and agency responses to bereaved individuals who were suicidal. Questions were raised around clinical effectiveness, reliability and professional accountability. The study highlighted ethical issues centred on documentation, user participation and consent, and found staff training was variable across the 10 hospices. The findings have informed the development of a post-bereavement service model which has been subsequently implemented across Marie Curie Cancer Care.

Multidisciplinary Teamwork in Autism: Can One Size Fit All?

Multidisciplinary practice has become an accepted approach in many education and social and health care fields. In fact, the right to a multidisciplinary assessment is enshrined in the United Nations Convention of the Rights for Persons with Disabilities (United Nations, 2007). In order to avert a 'one size fits all' response to particularly heterogeneous diagnoses, such as autism spectrum disorders (ASD), the National Institute for Clinical Excellence (NICE) recommends multidisciplinary input. Yet, multidisciplinarity lacks empirical evidence of effectiveness, is fraught with conceptual difficulties and methodological incompatibilities, and therefore there is a danger of resorting to an ill-defined eclectic 'hodgepodge' of interventions. Virtually all evidence-based interventions in autism and intellectual disabilities are behaviourally based. Not surprisingly, therefore, professionals trained in behaviour analysis to international standards are increasingly becoming key personnel in multidisciplinary teams. In fact, professionals from a range of disciplines seek training in behaviour analysis. In this article we brought together a multidisciplinary group of professionals from education, health, and social care, most of whom have a dual qualification in an allied health, social care, or educational profession, as well as in behaviour anlaysis. Together we look at the initial training in these professions and explore how behaviour analysis can offer a common and coherent conceptual framework for true multidisciplinarity, based on sound scientific knowledge about behaviour, without resort to reifying theories. We illustrate how this unifying approach can enhance evidence-based multidisciplinary practice so that 'one size' will fit all. Copyright © Australian Psychological Society Ltd 2014.

Lesiones abiertas del plexo braquial con compromiso vascular concomitante. Revisión sistemática de la literatura.

La presente investigación, intenta generar un impacto positivo dentro del ámbito médico-quirúrgico, ya que se espera que la revisión de la literatura genere mayor conocimiento sobre el manejo de las lesiones del plexo braquial con lesión vascular concomitante, ocasionada mediante un trauma abierto por herida causada por arma corto punzante, y con base en esto proponer una guía de manejo que se pueda aplicar en el día a día de todos aquellos especialistas quirúrgicos y no quirúrgicos para el tratamiento de dicha lesión. Es importante resaltar la dificultad metodológica presentada ante la poca validez de los estudios seleccionados, a pesar de que se aplicaron normas estrictas para la selección de los artículos. Las lesiones vasculares y nerviosas concomitantes del miembro superior no solo comprometen la viabilidad de la extremidad sino que además se constituyen en lesiones con secuelas severas desde el punto de vista funcional para el paciente. No se ha establecido un protocolo de manejo de estas lesiones. Los estudios realizados carecen de metodología adecuada de evaluación tanto en el momento de ingreso del paciente a urgencias como en su preoperatorio, postoperario y en las evaluaciones de los resultados funcionales de la extremidad una vez superada la lesión inicial. No hay una evolución consignada en la literatura con respecto al manejo integral de estos pacientes, que nos permita discernir con respecto al momento adecuado de la reparación nervios. El establecimiento de una guía clínica para cirujanos vasculares y cirujanos de mano para el manejo integral de este tipo de lesiones es apremiante. Los costos de tratamiento y rehabilitación de este tipo de pacientes son indiscutiblemente elevados desde todo punto de vista, pero es definitivo que el resultado funcional es mejor cuando se establece un manejo sistemático que incluya el manejo vascular y el manejo de la lesión neurológica de una forma integral.

Manejo de lesiones abiertas del plexo braquial con compromiso vascular concomitante. Revisión sistemática de la literatura

El manejo de las lesiones de plejo braquial ha sido ampliamente discutido e investigado, especialmente en las lesiones cerradas por tracción. Las lesiones abiertas con compromiso vascular, muchas veces comprometen la viabilidad de la extremidad o la vida del paciente; son de difícil manejo con prioridades distintas, tiempos de establecimiento de los procedimientos que varían respecto a los hallazgos con resultados funcionales pobres por el diagnostico tardío de la lesión nerviosa. Se plantean interrogantes desde el punto de vista vascular y de la lesión nerviosa. se realiza una revisión sistemática de la literatura, encontrando puntos importantes con respecto a la exploración, el momento de la reparación nerviosa pero sin establecer resultados funcionales claros ante la deficiencia metodológica de los estudios encontrados.

Practices and views on fetal heart monitoring:A structured observation and interview study

Objective: To assess and explain deviations from recommended practice in National Institute for Clinical Excellence (NICE) guidelines in relation to fetal heart monitoring. Design: Qualitative study. Setting: Large teaching hospital in the UK. Sample: Sixty-six hours of observation of 25 labours and interviews with 20 midwives of varying grades. Methods: Structured observations of labour and semistructured interviews with midwives. Interviews were undertaken using a prompt guide, audiotaped, and transcribed verbatim. Analysis was based on the constant comparative method, assisted by QSR N5 software. Main outcome measures: Deviations from recommended practice in relation to fetal monitoring and insights into why these occur. Results: All babies involved in the study were safely delivered, but 243 deviations from recommended practice in relation to NICE guidelines on fetal monitoring were identified, with the majority (80%) of these occurring in relation to documentation. Other deviations from recommended practice included indications for use of electronic fetal heart monitoring and conduct of fetal heart monitoring. There is evidence of difficulties with availability and maintenance of equipment, and some deficits in staff knowledge and skill. Differing orientations towards fetal monitoring were reported by midwives, which were likely to have impacts on practice. The initiation, management, and interpretation of fetal heart monitoring is complex and distributed across time, space, and professional boundaries, and practices in relation to fetal heart monitoring need to be understood within an organisational and social context. Conclusion: Some deviations from best practice guidelines may be rectified through straightforward interventions including improved systems for managing equipment and training. Other deviations from recommended practice need to be understood as the outcomes of complex processes that are likely to defy easy resolution. © RCOG 2006.

Photodynamic therapy with verteporfin for juxtafoveal choroidal neovascularisation secondary to pathological myopia

The treatment of choroidal neovascularisation (CNV) secondary to pathological myopia has presented a number of problems to ophthalmologists over the years, but the advent of photodynamic therapy (PDT) with verteporfin has changed how we manage these patients. Until PDT became available, the use of laser photocoagulation for extra and juxtafoveal lesions had been shown to be effective in the short term in preventing loss of vision, although the risk of regrowth of CNV and undertreatment were well recognised. However, even in apparent successful cases of photocoagulation, laser scar enlargement and creepage into the fovea in the mid-to-long term often occurred with resulting loss of central vision.1 Other options for treatment were very limited with little evidence that other modalities such as transpupillary thermotherapy or submacular surgery and macular transplantation surgery would be successful in highly myopic eyes. The evidence for the role of PDT and verteporfin CNV secondary to pathological myopia comes from the verteporfin in photodynamic therapy (VIP) study that has shown how effective this treatment is in eyes with subfoveal CNV.2, 3 Now in this publication, Lam et al4 from Hong Kong have shown that PDT is also effective in juxtafoveal CNV, with high myopia. They performed a small prospective study of 11 patients of mean age 44.8 years, with 12 months of follow-up. They found that there was a mean improvement of 1.8 lines of LogMAR best-corrected visual acuity (BCVA) at 12 months, with a mean number of 2.3 PDT treatments. The most rapid improvement occurred within the first 3 months of treatment and by 12 months none of the patients had suffered a deterioration in BCVA from baseline. There were no cases of adverse effects from the infusion or laser treatment. For ophthalmologists dealing with patients with CNV secondary to causes other than AMD, this is further evidence of the effectiveness of PDT with verteporfin in maintaining vision. These patients are likely to be younger than those with AMD and are likely to be in active employment and supporting families, and clearly the preservation of best vision possible is imperative in this group. It is therefore encouraging for ophthalmologists in the United Kingdom that the verteporfin in PDT Cohort Study (VPDT Study) includes the ability to treat patients with subfoveal CNV secondary to high myopia if they fulfill National Institute of Clinical Excellence guidelines, and will allow representations to be made on an individual basis for treatment of juxtafoveal lesions.5 For those ophthalmologists used to juggling increased patient expectations with scarce NHS resources, this is promising news and will allow us to offer a better standard of care to our patients.

Guideline-based decision support has a small, non-sustained effect on transthoracic echocardiography ordering frequency.

BACKGROUND: Guidance for appropriate utilisation of transthoracic echocardiograms (TTEs) can be incorporated into ordering prompts, potentially affecting the number of requests. METHODS: We incorporated data from the 2011 Appropriate Use Criteria for Echocardiography, the 2010 National Institute for Clinical Excellence Guideline on Chronic Heart Failure, and American College of Cardiology Choosing Wisely list on TTE use for dyspnoea, oedema and valvular disease into electronic ordering systems at Durham Veterans Affairs Medical Center. Our primary outcome was TTE orders per month. Secondary outcomes included rates of outpatient TTE ordering per 100 visits and frequency of brain natriuretic peptide (BNP) ordering prior to TTE. Outcomes were measured for 20 months before and 12 months after the intervention. RESULTS: The number of TTEs ordered did not decrease (338±32 TTEs/month prior vs 320±33 afterwards, p=0.12). Rates of outpatient TTE ordering decreased minimally post intervention (2.28 per 100 primary care/cardiology visits prior vs 1.99 afterwards, p<0.01). Effects on TTE ordering and ordering rate significantly interacted with time from intervention (p<0.02 for both), as the small initial effects waned after 6 months. The percentage of TTE orders with preceding BNP increased (36.5% prior vs 42.2% after for inpatients, p=0.01; 10.8% prior vs 14.5% after for outpatients, p<0.01). CONCLUSIONS: Ordering prompts for TTEs initially minimally reduced the number of TTEs ordered and increased BNP measurement at a single institution, but the effect on TTEs ordered was likely insignificant from a utilisation standpoint and decayed over time.

Management of Hyperphosphataemia in Chronic Kidney Disease:Summary of National Institute for Health and Clinical Excellence (NICE) Guideline

Bone disease and ectopic calcification are the two main consequences of hyperphosphataemia of chronic kidney disease (CKD). Observational studies have demonstrated that hyperphosphataemia in CKD is associated with increased mortality. Furthermore, the use of phosphate binders in dialysis patients is associated with significantly lower mortality. The UK Renal Registry data show significant underachievement of phosphate targets in dialysis patients. It is believed to be due to wide variation in how management interventions are used. The National Institute for Health and Clinical Excellence (NICE) has developed a guideline on the management of hyperphosphataemia in CKD. This is based on the evidence currently available using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. This review outlines the recommendations including research recommendations and discusses methodology, rationale and challenges faced in developing this guideline and the health economic model used to assess the cost-effectiveness of different phosphate binders. © 2013 S.
