To investigate the baseline status of patients' awareness, knowledge, and attitudes to patient safety in China, and to determine the factors that influence patients' involvement in patient safety. ⋯ The majority of patients surveyed expressed willingness to contribute to patient safety, but their knowledge about patient safety practices was generally very limited.

Postextubation problems such as laryngeal edema and reintubation are common complications after tracheal intubation. The cuff-leak test has been proposed as a method of identifying those patients at high risk in clinical practice, but its efficacy remains controversial. ⋯ Our results suggest the cuff-leak test accurately predicts which adult patients are at high risk of postextubation airway complications, but randomized controlled trials are needed to further assess this diagnostic strategy.

The Iranian Registry of Clinical Trials (IRCT) was established as a primary registry on December 4 2008 and has registered over 1350 trials by June 2011. Many researchers are still unaware of the need for registration of trials before recruiting the first patient and the proportion of retrospectively registered trials is likely to grow until this awareness increases. We sought to investigate the timing of the registrations in IRCT and to explore strategies to overcome this. ⋯ The rapid increase in the number of registered trials is an indication of strong implementation of the registration policy. This comes partly at the expense of an increased proportion of retrospective registrations. While this may be understandable at the beginning, it is clearly not acceptable and measures should be adopted to increase the proportion of prospectively registered trials and to make trial registration an integral part of the research culture.

To systematically assess the main clinical features of Houttuynia injection-associated adverse drug reactions (ADRs), as described in published reports, and to contribute to the post-marketing re-evaluation and clinical practices of Houttuynia injection. ⋯ The respiratory system was the most common system treated in Houttuynia injection ADR cases. It was also the most common site of ADR symptoms. The ADRs of Houttuynia injection were serious. The precautions should be taken to prevent the anaphylactic shock. Intravenous injection and the combination with with cephalosporins, penicillins, and macrolides increased the ADR risk of Houttuynia injection.

We conducted a literature review on adverse drug reactions (ADRs) related to 33 kinds of traditional Chinese medicine injections (CMIs) on China's National Essential medicines List (2004 edition). We aimed to retrieve basic ADR information, identify trends related to CMIs, and provide evidence for the research, development, and application of CMIs. ⋯ (1) Articles published on CMI-related ADRs increased over time, but overall the research is of low quality and is scattered through a large number of sources. (2) Four CMIs (Shuanghuanglian, Ciwujia, Yuxingcao, and Yinzhihuang injections) had been suspended for clinical use or sale. (3) There is an urgent need for a clear standard to grade ADRs of CMIs in order to better risk manage. (4) It is necessary to continually re-evaluate the safety of CMIs and to promote rational use of CMIs.
