A shortcut review was carried out to establish whether dousing areas of contact with vinegar could relieve the symptoms of Irukandji syndrome. Four studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is there is a lack of evidence for effectiveness and the latest local guidelines should be followed.

To create and validate a simple clinical score to estimate the probability of admission at the time of triage. ⋯ This simple, 6-variable score accurately estimates the probability of admission purely from triage information. Most patients could accurately be assigned to 'admission likely', 'admission unlikely', 'admission very unlikely' etc., by setting appropriate cut-offs. This could have uses in patient streaming, bed management and decision support. It also has the potential to control for demographics when comparing performance over time or between departments.

Randomized Controlled Trial
Exploration of the impact of a voice activated decision support system (VADSS) with video on resuscitation performance by lay rescuers during simulated cardiopulmonary arrest.
To assess whether access to a voice activated decision support system (VADSS) containing video clips demonstrating resuscitation manoeuvres was associated with increased compliance with American Heart Association Basic Life Support (AHA BLS) guidelines. ⋯ The use of an audio and video assisted decision support system during a simulated out-of-hospital cardiopulmonary arrest prompted lay rescuers to follow cardiopulmonary resuscitation (CPR) guidelines but was also associated with an unacceptable delay to starting chest compressions. Future studies should explore: (1) if video is synergistic to audio prompts, (2) how mobile technologies may be leveraged to spread CPR decision support and (3) usability testing to avoid unintended consequences.

Hospital mortality rates could be useful indicators of quality of care, but careful statistical analysis is required to avoid erroneously attributing variation in mortality to differences in health care when it is actually due to differences in case mix. The summary hospital mortality indicator is currently used by the English National Health Service (NHS). It adjusts mortality rates up to 30 days after discharge for patient age, sex, type of admission, year of discharge, comorbidity, deprivation and diagnosis. ⋯ Furthermore, concerns have been raised that the proportion of preventable deaths among hospital admissions is too small to produce a reliable 'signal' in risk-adjusted mortality rates. This provides hospital managers, regulators and clinicians with a considerable dilemma. Variation in mortality rates cannot be ignored, as they might indicate unacceptable variation in healthcare and avoidable mortality, but they also cannot be reliably used to judge the quality of healthcare, based on current evidence.
