Revisiting the Great Ormond Street Hospital protocol for ward decannulation of children with tracheostomy.

INTRODUCTION: Tracheostomy decannulation is an important and final step in managing patients once the underlying issue requiring a tracheostomy resolves. However, no consensus exists on the optimal method to decannulate a paediatric patient. We revisit the Great Ormond Street Hospital (GOSH) tracheostomy decannulation protocol, a 5-day process involving downsizing the tracheostomy tube, capping, and observation, to evaluate its effectiveness and assess if changes to the protocol are required. METHOD: This is a retrospective study, reviewing patient records between April 2018 and April 2023 from a single quaternary care centre. Data extracted include comorbidities, age at the time of decannulation, duration of tracheostomy, reason for tracheostomy insertion, whether a decannulation attempt was successful or not, and the timings of decannulation failure. RESULTS: 66 patients that met the selection criteria underwent a decannulation trial between April 2018 and April 2023. 32 patients were male, and 34 patients were female. Age at attempted decannulations ranged from 1 year to 18 years, with an average age of 6.1 years. There were a total of 93 attempts at decannulation, with 51 (54.8%) successful attempts, 35 (56.5%) first decannulation attempt successes, and 42 (45.2%) unsuccessful attempts. 17 patients had 2 attempts at decannulation, and 4 patients had 3 or more attempts at decannulation. Of the unsuccessful attempts, patients mostly failed on capping of the tracheostomy tube with 33 failures (35.5%). CONCLUSION: The GOSH protocol achieved similar success rates to comparable protocols. The protocol's multi-step approach provides thorough evaluation and support for patients during the decannulation process, and its success on a complex patient cohort supports its continued use.

Communication in the intensive care unit during COVID-19: early experience with the Nightingale Communication Method.

OBJECTIVE: To assess the utility and frequency of use of the Nightingale Communication Method, during the early operational phase of the Nightingale Hospital London (NHL) 4000-bed field hospital's intensive care unit. DESIGN: Survey-based cross-sectional assessment. SETTING: The intensive care unit at the Nightingale London hospital. PARTICIPANTS: Staff working in the clinical area and therefore requiring full personal protective equipment (PPE). INTERVENTION: Survey of all staff members sampled from a single shift at the Nightingale Hospital. This investigated perceived utility and actual use of identification methods (name and role labels on visors and gowns, coloured role identification tapes) and formal hand signals as an adjunctive communication method. MAIN OUTCOME MEASURE: Self-reported frequency of use and perceived utility of each communication and personnel identification adjunct. RESULTS: Fifty valid responses were received (72% response rate), covering all clinical professional groups. Prominent name/role identifications and coloured role identification tapes were very frequently used and were perceived as being highly useful. Formal hand signals were infrequently used and not perceived as being beneficial, with respondents citing use of individual hand signals only in specific circumstances. CONCLUSION: PPE is highly depersonalizing, and interpersonal identification aids are very useful. Despite being difficult, verbal communication is not completely prohibited, which could explain the low utility of formal hand signals. The methods developed at the Nightingale hospital have enhanced communication in the critical care, field hospital setting. There is potential for wider application to a variety of healthcare settings, in both the current situation and future pandemic scenarios.

Plant-Dominant Low-Protein Diet for Conservative Management of Chronic Kidney Disease.

Chronic kidney disease (CKD) affects >10% of the adult population. Each year, approximately 120,000 Americans develop end-stage kidney disease and initiate dialysis, which is costly and associated with functional impairments, worse health-related quality of life, and high early-mortality rates, exceeding 20% in the first year. Recent declarations by the World Kidney Day and the U.S. Government Executive Order seek to implement strategies that reduce the burden of kidney failure by slowing CKD progression and controlling uremia without dialysis. Pragmatic dietary interventions may have a role in improving CKD outcomes and preventing or delaying dialysis initiation. Evidence suggests that a patient-centered plant-dominant low-protein diet (PLADO) of 0.6­0.8 g/kg/day composed of >50% plant-based sources, administered by dietitians trained in non-dialysis CKD care, is promising and consistent with the precision nutrition. The scientific premise of the PLADO stems from the observations that high protein diets with high meat intake not only result in higher cardiovascular disease risk but also higher CKD incidence and faster CKD progression due to increased intraglomerular pressure and glomerular hyperfiltration. Meat intake increases production of nitrogenous end-products, worsens uremia, and may increase the risk of constipation with resulting hyperkalemia from the typical low fiber intake. A plant-dominant, fiber-rich, low-protein diet may lead to favorable alterations in the gut microbiome, which can modulate uremic toxin generation and slow CKD progression, along with reducing cardiovascular risk. PLADO is a heart-healthy, safe, flexible, and feasible diet that could be the centerpiece of a conservative and preservative CKD-management strategy that challenges the prevailing dialysis-centered paradigm.

What should be done to support the mental health of healthcare staff treating COVID-19 patients?

There is an urgent need to provide evidence-based well-being and mental health support for front-line clinical staff managing the COVID-19 pandemic who are at risk of moral injury and mental illness. We describe the evidence base for a tiered model of care, and practical steps on its implementation.

Understanding factors influencing vulnerable older people keeping warm and well in winter: a qualitative study using social marketing techniques.

OBJECTIVES: To understand the influences and decisions of vulnerable older people in relation to keeping warm in winter. DESIGN: A qualitative study incorporating in-depth, semi-structured individual and group interviews, framework analysis and social marketing segmentation techniques. SETTING: Rotherham, South Yorkshire, UK. PARTICIPANTS: 50 older people (>55) and 25 health and social care staff underwent individual interview. The older people also had household temperature measurements. 24 older people and 19 health and social care staff participated in one of the six group interviews. RESULTS: Multiple complex factors emerged to explain whether vulnerable older people were able to keep warm. These influences combined in various ways that meant older people were not able to or preferred not to access help or change home heating behaviour. Factors influencing behaviours and decisions relating to use of heating, spending money, accessing cheaper tariffs, accessing benefits or asking for help fell into three main categories. These were situational and contextual factors, attitudes and values, and barriers. Barriers included poor knowledge and awareness, technology, disjointed systems and the invisibility of fuel and fuel payment. Findings formed the basis of a social marketing segmentation model used to develop six pen portraits that illustrated how factors that conspire against older people being able to keep warm. CONCLUSIONS: The findings illustrate how and why vulnerable older people may be at risk of a cold home. The pen portraits provide an accessible vehicle and reflective tool to raise the capacity of the NHS in responding to their needs in line with the Cold Weather Plan.

Evaluation of a commercial vascular clip: risk factors and predictors of failure from in vitro studies.

OBJECTIVE: To assess risk factors and predictors of failure of the Hem-o-lok(TM) vascular clip (Weck Closure Systems, Research Triangle Park, NC, USA) using vessels harvested from a porcine model. MATERIALS AND METHODS: Vessels of various diameters were harvested from a porcine model, clipped at 90 degrees or 45 degrees using the Hem-o-lok clip and then cut either flush or with a 1-mm cuff. The vessels were then connected to a burst-pressure device and pressures required to burst the clip or to cause it to leak were measured. RESULTS: The Hem-o-lok clip leaked or burst when the vessel to which it was applied was cut flush. The clip became even more likely to fail if the angle of application of the clip was not at 90 degrees to the vessel surface. CONCLUSION: The Hem-o-lok vascular clip is safe if it is applied at 90 degrees to the vessel surface and, more importantly, if a 1-mm cuff is left between the clip and the point at which the vessel is divided. We would therefore discourage the practice of not leaving this cuff of tissue, in an attempt to maximize vessel length during laparoscopic donor nephrectomy.

Can we develop a protocol for the safe decannulation of tracheostomies in children less than 18 months old?

Expanding indications for airway and head and neck surgery have led to a number of children under 18 months of age being deemed suitable for decannulation of their tracheostomies. We present four cases to illustrate the particular problems encountered in this age group and suggest modifications to our previously-published decannulation protocol.
