Lateral positioning for critically ill adult patients: a systematic review

A systematic review was undertaken to evaluate the effect of lateral positioning compared to other body positions on morbidity, mortality, and clinical adverse events for critically ill patients. Twenty three studies met the criteria. Hypoxaemia was not consistently reported. No clinical practice recommendations could be drawn from the included studies due to methodological shortcomings.

Young adult voting decision-making: Studying the effect of usage from a consumer behaviour perspective

This study investigates the application of consumer behaviour theory to young Australian adults’ voting decision-making. Previous decision-making studies identified constructs of subjective knowledge, involvement, information seeking, satisfaction, confidence, and stability as key factors in voting decision-making. This research tests the relationship that these factors have with the consumer behaviour concept of usage. A new concept, commitment to vote, is also considered for Australia’s compulsory voting context. Data were gathered from a sample of 257 Australian citizens between the ages of 18 and 25. Exploratory factor analysis produced nine factors, and MANOVA and ANOVA were used to test the differences between three usage groups: voluntary users, involuntary users, and never trieds. The results illustrate that usage has a significant influence on information seeking, commitment to voting, satisfaction with voting choice, and stability in voting decision-making. Therefore, usage is a key element in voter decision-making and needs to be included in future studies.

Mortality and use of the auxiliary score in extensive toxic epidermal necrolysis patients admitted to an adult burns referral centre

 Background: Toxic epidermal necrolysis (TEN) is a rare but fatal condition characterised by cutaneous exfoliation of the dermoepidermal layer and mucosal surfaces. Extensive TEN with epidermal detachment >30% of the total body surface area has been associated with a high mortality. Objective: This study aims to evaluate factors associated with mortality in extensive TEN. In the absence of data to qualify scoring systems such as SCORTEN, this study also aims to evaluate the use of the auxiliary score as a tool for calculating expected mortality. Methods: A retrospective chart review of all patients presenting to our burns service with extensive TEN was undertaken. Application and evaluation of the auxiliary score was also undertaken for this patient population. Results: In extensive TEN, age and delay in admission to a burns centre were factors associated with mortality. Applying the auxiliary score to our patient population, there were no significant differences between expected mortality and observed mortality. Conclusion: Mortality was associated with age and delay in definitive treatment in extensive TEN. Whilst SCORTEN is the gold standard prognostic tool for patients with TEN, in the absence of SCORTEN values, the auxiliary score provides an alternative scoring system to evaluate expected mortality.
