Re: Rationalising medications through deprescribing
We read with interest the excellent article by Professor Avery and colleagues on the value and benefit of deprescribing. 1 Deprescribing should be integral to every clinician’s practice, and as such in 2013, the General Medical Council highlighted the importance of regular review of a patient's medication. Deprescribing should be undertaken by anaesthetists and intensivists, 3 and as such we are in a position to advise on the deprescribing of drugs that may have been commenced during critical illness eg amiodarone for atrial fibrillation or opioids for the management of post-surgical pain (PSP).
Poor deprescribing is pivotal in the the global prescribed opioid crisis, which is a well documented phenomenon.4 Research from the US has emerged that following surgery the risk of subsequent opioid dependency in opioid naïve patients may be as high as 6.5%5 . Interestingly, the 3 biggest risk factors for subsequent opioid dependence in the US have been identified as the use of modified release opioid preparations eg Oxycontin ®; drugs going onto repeat prescriptions; and the duration of the prescription. 6,7
We therefore advocate that as well as deprescribing, we need to reflect on prescribing habits. Specifically in view of the opioid crisis that is beginning to be appreciated in the UK,8 we need to avoid the use of modified release opioid preparations for acute pain, which is in line with North American and Antipodean recommendations, 9 we need to avoid opioids prescribed for acute pain continuing onto repeat prescriptions and we need to limit the size and duration of our prescriptions.
