Weaning from ventilation

Aims/purpose: Getting off the ventilator is an important patient-centred outcome for patients with acute respiratory failure. It signifies an improvement in patient condition, enables easier communication, reduces fear and anxiety and consequently a reduced requirement for sedatives. Weaning from ventilation therefore is a core ICU nursing task that is addressed in this presentation.
Presentation description: There are different schools of thought on when ventilator weaning begins including: (a) from intubation with titration of support; and (b) only when the patient’s condition improves. There are also different schools of thought on how to wean including gradual reductions in ventilator support to: (a) a low level consistent with extubation; or (b) to a level to attempt a spontaneous breathing trial followed by extubation if successful. Regardless of the approach, what is patient-relevant is the need to determine early when the patient may be ‘ready’ to discontinue ventilation. This time point can be assessed using simple criteria and should involve all ICU staff to the level of their experience. This presentation challenges the notion that only senior nurses or nurses with a ‘weaning course’ should be involved in the weaning process and proposes opportunities for engaging nurses with all levels of experience.
Conclusion: An ICU nursing taskforce that is focused and engaged in determining patient readiness for weaning can make a strong contribution to patient-relevant outcomes.

Making personalised nutrition the easy choice: Creating policies to break down the barriers and reap the benefits

Personalised diets based on people’s existing food choices, and/or phenotypic, and/or genetic information hold potential to improve public dietary-related health. The aim of this analysis, therefore, has been to examine the degree to which factors which determine uptake of personalised nutrition vary between EU countries to better target policies to encourage uptake, and optimise the health benefits of personalised nutrition technology. A questionnaire developed from previous qualitative research was used to survey nationally representative samples from 9 EU countries (N = 9381). Perceived barriers to the uptake of personalised nutrition comprised three factors (data protection; the eating context; and, societal acceptance). Trust in sources of information comprised four factors (commerce and media; practitioners; government; family and, friends). Benefits comprised a single factor. Analysis of Variance (ANOVA) was employed to compare differences in responses between the United Kingdom; Ireland; Portugal; Poland; Norway; the Netherlands; Germany; and, Spain. The results indicated that respondents in Greece, Poland, Ireland, Portugal and Spain, rated the benefits of personalised nutrition highest, suggesting a particular readiness in these countries to adopt personalised nutrition interventions. Greek participants were more likely to perceive the social context of eating as a barrier to adoption of personalised nutrition, implying a need for support in negotiating social situations while on a prescribed diet. Those in Spain, Germany, Portugal and Poland scored highest on perceived barriers related to data protection. Government was more trusted than commerce to deliver and provide information on personalised nutrition overall. This was particularly the case in Ireland, Portugal and Greece, indicating an imperative to build trust, particularly in the ability of commercial service providers to deliver personalised dietary regimes effectively in these countries. These findings, obtained from a nationally representative sample of EU citizens, imply that a parallel, integrated, public-private delivery system would capture the needs of most potential consumers.
