Lesson of the month 1: Acute flecainide overdose and the potential utility of lipid emulsion therapy.
Lipid-emulsion therapy (Intralipid®) has been advocated as a potential treatment for the management of cardio-toxicity arising from lipid-soluble drugs, particularly those acting upon sodium channels. This, on the basis of a number of ex vivo studies and animal models, suggests that partitioning a drug into lipid could alter its pharmacokinetics and result in significant clinical improvements. Its subsequent use in clinical case series has been seen as confirmation of this mechanism of action. While there are undoubtedly instances where lipid emulsion therapy has been associated with a desirable outcome in humans, as described in this case report, clinicians are reminded that they should not attribute causality, on this basis alone.

When nobody or nothing notices an error, it may turn into patient harm. We show that medical devices ignore many errors, and therefore do not adequately support patient safety. In addition to causing preventable patient harm, errors are often reported ignoring potential flaws in medical device design, and front line staff may therefore be inappropriately blamed. We present some suggestions to improve reporting and the procurement of hospital equipment.

The European Society of Cardiology (ESC) and UK National Institute for Health and Care Excellence (NICE) have recently published guidelines for investigating patients with suspected coronary artery disease (CAD). Both provide a risk score (RS) to assess the pre-test probability for CAD to guide clinicians to undertake the most effective investigation. The aim of the study was to establish whether there is a difference between the two RS models. We retrospectively reviewed records of 479 patients who presented to a UK district general hospital with chest pain between August 2011 and April 2013. ⋯ The difference in mean RS was smaller in patients with typical chest pain (13.0%). When we divided the cohort based on NICE criteria into 'high'- and 'low'-risk groups, the difference in the mean RS was 24.3% in the 'high'-risk group (p<0.001) compared with 2.8% in the 'low'-risk group. The UK NICE risk score model overestimates risk compared with the ESC model.

The acceptability, uptake and effectiveness of a new referral tool - the diabetes patient at risk (DPAR) score - were evaluated and the timeliness of review of referred inpatients by the diabetes team was measured. For this, a snapshot survey of ward healthcare professionals (HCPs) and a review of all DPAR referrals to the diabetes team between 1 September 2013 and 31 January 2014 were undertaken. ⋯ All DPAR referrals were reviewed within the stipulated time period in November 2013. Overall, the DPAR system was well accepted, successfully identified appropriate referrals and facilitated referrals in a timely manner to the diabetes team.

Adolescence represents a critical period of development during which personal lifestyle choices and behaviour patterns establish, including the choice to be physically active. Physical inactivity, sedentary behaviour and low cardiorespiratory fitness are strong risk factors for the development of chronic diseases with resulting morbidity and mortality, as well as economic burden to wider society from health and social care provision, and reduced occupational productivity. ⋯ Every encounter represents an opportunity to ask about physical activity, provide advice, or signpost to appropriate pathways or opportunities. Key initial targets include getting everyone to reduce their sedentary behaviour and be more active, with even a little being more beneficial than none at all.
