Routine cognitive screening for older people undergoing major elective surgery: Benefits, risks and costs.
Anaesth Intensive Care
September 2024
Cognitive impairment and older age are major risk factors for postoperative delirium. Professional societies have advocated preoperative screening to identify at-risk individuals for implementation of interventions, which have moderate effectiveness in preventing delirium. However, it remains unclear from the guidelines whether screening should be completed routinely for all older individuals or targeted, and also which specific screening tool is preferred.

Some presentations and admissions may be avoidable. In 2013, Bankstown-Lidcombe Hospital introduced a subacute geriatric outreach service (SGOS), which had little impact on reducing ED presentations.

- Falls in hospitals happen a lot and can cause injuries in 70% of cases, leading to longer hospital stays and some patient deaths.
- There isn't enough good research to know the best ways to prevent falls, as different strategies have worked for some groups and not in others.
- The article talks about new ways to prevent falls, like using video clips for patient education and keeping high-risk patients in a supervised area, but more research is needed to confirm these methods.
The most recent hypothesis of the development of small vessel vascular dementia (VaD) emphasises the role of blood-brain barrier (BBB) dysfunction. It is hypothesised that certain genetic polymorphisms of the BBB tight junction claudin-1 protein, in combination with adverse environmental risk factors, increase the risk of BBB dysfunction and small vessel VaD. In this case-control study, 97 control participants, with a mean Mini Mental State Exam (MMSE) score of 29.

The aim of our study was to investigate if candidate risk factors could predict short-term mortality risk in poststroke patients who had PEG tube insertion for persistent dysphagia.
Methods: This was a retrospective study of 3504 consecutive stroke patients admitted to two metropolitan hospitals during the period January 2005 to December 2013 and who also underwent PEG insertion for feeding due to persistent dysphagia.
