THE world of medical apps is an ever-expanding one populated by both the ingeniously innovative and the downright dodgy.
Who knew you could cure acne using the light from a mobile phone or augment breast size by blaring baby cries out of your device 20 times a day? Others claim to allow users to select the sex of their baby by entering certain times, dates and phases of the moon.
While the market is awash with apps making all manner of dubious medical claims, there are many that have proved popular with clinicians. There are tools to assist diagnosis, staging or treatment (such as calculating fluid requirements for burns patients), as well as countless others that can help monitor and promote general health and wellbeing.
With so much choice, it is important that doctors take a cautious approach, researching as much as possible the app’s origins and reliability and looking out for positive/negative reviews by fellow healthcare professionals.
One helpful guide is to look out for the CE mark, indicating it complies with essential criteria set out under European law. This applies specifically to apps with a medical purpose (i.e. those supporting diagnosis or clinical decisions) which are defined by law as "medical devices" and regulated in the UK by the MHRA.
The first app to be officially registered by the MHRA was Mersey Burns just over three years ago. It is a popular clinical tool (available free for Apple and Android devices) for estimating burn area percentages, prescribing fluids using the Parkland formula, and recording patients’ details (being mindful of confidentiality). It was developed by plastic surgeons at St Helen’s and Knowsley NHS Trust and has won a number of innovation awards as well as favourable reviews.
In its April 2015 guidance Using apps in clinical practice, the Royal College of Physicians of London says doctors should not use medical apps, including web apps, that do not have a CE mark. It is worth ensuring that the specific version of the app you are using is CE marked, rather than relying on the general information in the online app store.
Apps which do not require a CE mark are those which do not use patient-specific information and only perform administrative functions. This might include those offering general guidance or supporting training.
While it is a useful indicator, the RCP goes on to state: "Unfortunately, even if an app has a CE mark, that does not mean that it meets best practice, has been tested for accuracy or benefits in clinical use, or is applicable to the patient/decision for which it is being used."
Most importantly, the College adds: "Always exercise professional judgement before relying on information from an app."
So what are some of the commonly used apps for doctors on the market? Those listed below have received positive reviews, but there are many others available. Doctors are advised to carefully consider any app before downloading and using it in clinical practice. The following are in no particular order (MDDUS doesn’t endorse or approve any app):
