Observational Study
Prehospital electrocardiogram shortens ischaemic time in patients with ST-segment elevation myocardial infarction.
Total ischaemic time should be shortened as much as possible in patients with ST-segment elevation myocardial infarction (STEMI). This study evaluated whether prehospital 12-lead electrocardiogram (ECG) could shorten system delay in STEMI management. ⋯ Prehospital ECG shortened ischaemic time prior to hospital admission.

Acute renal failure secondary to contrast-induced acute kidney injury (CI-AKI) is one of the most commonly encountered problems in hospitalised patients. The CI-AKI may lead to the development of persistent renal disease, causing significant morbidity and mortality in high-risk patients. Statins are increasingly recognised as effective in preventing CI-AKI. In this review, we reviewed the literature on statin use for prophylaxis of CI-AKI, its potential benefits, and adverse effects. The aim of the present review was to reveal gaps and discrepancies in the available literature, and to identify areas for future research. ⋯ Statin therapy can be used as an adjunct to usual prophylactic measures such as adequate hydration and use of low-volume contrast media. Large well-designed trials on the effects of short-term high-dose statin use in preventing CI-AKI should be conducted, to eliminate any form of discrepancy among results, and to clarify any potential adverse effects.

The perceptions of medical futility and decisions about termination of resuscitation (TOR) for out-of-hospital cardiac arrest (OHCA) are highly heterogeneous and dependent on the practice of the attending emergency physicians. The objective of this study was to report and investigate the knowledge, attitudes, and practices regarding medical futility and TOR during management of OHCA in Hong Kong. ⋯ Clinical practice and behaviour of TOR was not demonstrated to have associations with knowledge or attitude. Status as a Fellow of the Hong Kong College of Emergency Medicine or Advanced Cardiac Life Support instructor were the only two parameters identified that had significant relationships with earlier TOR in medically futile patients with OHCA.

This serial cross-sectional survey study aimed to review the trend in various infection control practices in residential care homes for the elderly (RCHEs) in Hong Kong from 2005 to 2014. ⋯ For infection control practice to continue improving, more effort should be made to enhance and maintain proper practice, and to mitigate the challenge posed by the high turnover rates of healthcare workers in RCHEs. Introduction of self-audits on infection control practices should be considered.
