Evaluate the effect of IV line labels on nurses' identification of high-alert medications in a simulated scenario of multiple infusions for critically ill patients.
Randomised crossover simulation experimental study.
A study was conducted on 29 nurses working in intensive care for over 6 months. They were given two critical scenarios in a simulated environment, one with labels and the other without labels, involving multiple intravenous infusions. The nurses had to identify the medications infused into the critical patients' intravenous lines and disconnect a specific line. The data were collected and analysed to evaluate the errors made by the nurses in identifying and disconnecting the medications and the time they spent carrying out the tasks. The Wilcoxon test was used to analyse the variation in outcome before and after the intervention.
Approximately one-third of the study participants incorrectly identified the intravenous lines in both scenarios. There was no significant difference in the average number of errors between the scenarios with and without labels. However, the time taken to perform the tasks in the scenario with labels was 1 min less than in the scenario without labels, suggesting a potential efficiency gain.
The labels on the intravenous lines allowed for quick drug identification and disconnection. The professionals performed similarly in correctly recognising the high-alert medication intravenous lines, in the scenarios with or without labels.
The label can be used as a technology to prevent misidentification of high-alert medications administered to critically ill patients through intravenous lines, thereby enhancing medication safety in healthcare institutions.

No abstract available We aim the isolated and combined effects of sedentary behaviour exposure time and physical activity levels on muscle strength in older adults.
This prospective observational cohort study, analytical in nature, using exploratory survey methods and physical performance testing. With 5-year longitudinal follow-up (2015–2020).
A total of 459 older adults participated in the baseline, with a total of 224 being included/located again in the follow-up. We evaluate muscle strength using handgrip tests and sit-to-stand tests. The international physical activity questionnaire was used to measure physical activity and sedentary behaviour. Generalised Estimation Equations tested both independent and combined effects, reporting results as β coefficients and confidence intervals.
Older adults exhibiting low sedentary behaviour displayed enhanced handgrip strength compared to those with high sedentary behaviour. Notably, older adults who were sufficiently active with low sedentary behaviour, sufficiently active with high sedentary behaviour, and insufficiently active with low sedentary behaviour showed increased handgrip strength compared to their counterparts who were insufficiently active with high sedentary behaviour. This trend was consistent for lower limb strength.
Interventions that encourage a reduction in sedentary behaviour and an increase in physical activity are essential to maintain muscle strength among older adults.
The findings of this study underscore the importance of addressing both sedentary behaviour and physical activity levels in clinical interventions aimed at preserving muscle strength in older adults. Routine assessments of physical activity and sedentary behaviour could help tailor personalised exercise programs, potentially enhancing functional independence and reducing the risk of frailty and disability in older patients.
Patients were involved in the sample of the study.
This study was conducted in accordance with the Strengthening Research in Observational Studies in Epidemiology (STROBE) guidelines.
