Doctors increasingly rely on medical apps running on smart phones or tablet computers to support their work. However, these apps vary hugely in the quality of their data input screens, internal data processing, the methods used to handle sensitive patient data and how they communicate their output to the user. Inspired by Donabedian's approach to assessing quality and the principles of good user interface design, the Royal College of Physicians' Health Informatics Unit has developed and piloted an 18-item checklist to help clinicians assess the structure, functions and impact of medical apps. Use of this checklist should help clinicians to feel more confident about using medical apps themselves, about recommending them to their staff or prescribing them for patients.

Neutropenic sepsis is a life-threatening condition with mortality rates reported to range between 2 and 21% in adults. It can occur following chemotherapy treatment, due to disease (such as haematological conditions affecting the bone marrow) and in patients on disease-modifying agents (such as patients receiving methotrexate for rheumatoid arthritis). ⋯ Practice at Weston General Hospital has been audited at three time points since 2008 (in 2008, 2011 and 2013-14) during which there have been several service developments relevant to the management of neutropenic sepsis, including the introduction of an AOS in June 2013. The percentage of patients in which intravenous antibiotic 1-hour door-to-needle time was achieved has improved from 14% (2008) to 31% (2011) to 79% (2013-14) and neutropenic sepsis mortality has decreased from 39% (2008) to 14% (2011) to 0% (2013-14).

Acute kidney injury (AKI) - an abrupt deterioration in renal function - causes a rise in serum creatinine (SCr) or fall in urine output. It is common, occurring in up to 20% of hospital admissions. Importantly, even small rises in SCr are associated with increased risk of death and longer hospital stays. ⋯ In practice, AKI represents a heterogeneous group of conditions, encompassing impairments in both kidney structure and function. Delivering disease-specific treatment early in the course of AKI may improve outcomes. The provision of best-practice care for all will rely on a better understanding of risk, and frameworks of care that can be applied across a diverse patient group.

Acute kidney injury (AKI) is encountered commonly in HIV-positive patients admitted to the acute medical unit. The spectrum of AKI has changed in the era of combination anti-retroviral therapy, and now includes adverse effects of commonly used anti-retroviral drugs in addition to traditional precipitants such as severe sepsis or exposure to nephrotoxic antimicrobials. An accurate diagnosis requires careful integration of clinical data including volume status, history of potentially nephrotoxic exposures and consideration of immuno-virological status. This article provides an overview of common causes of AKI in HIV and presents a framework by which the acute care physician may approach the finding of an elevated serum creatinine in a patient with HIV.
