Pharmacists and medicines go hand in hand, so it’s no surprise that assisting patients with medicines is what pharm-assist are best at.
The thing with medicines is that despite how good they are, they work most effectively only when they are taken as prescribed. The act of ‘not taking medication as prescribed’ is known as non-adherence, a straight forward term for behaviour that emanates from a complex set of beliefs. The resulting behaviours are not conducive to optimising outcomes for patients’ health.
There are many perceptual and practical factors that influence the patient’s motivation and ability to adhere to agreed treatments(1), and it’s estimated that non-adherence is somewhere between 30-50%(2). This in turn results in poor health outcomes for the patient, but also it becomes costly for the NHS in terms of the medicines wasted (an estimated £110 million worth of medicines are returned to pharmacies annually)(3) and the burden this creates for the healthcare system to keep on offering alternatives.
Non-adherence is not just a problem for developed countries, but places a burden on medicines outcomes globally; there are the same perceptual and practical concerns for developing countries(4,5). Regardless of location, once patients gain access to medicines trade-off between necessity (needing the medicines) versus the concerns (e.g. about potential long-term side-effects) come into play. This underpins a common need for healthcare systems, of all sizes and resource levels, to adopt ways to improve adherence.
What’s the solution?
The good news is, there are many ways to help patients remain adherent to their medicines and the role for pharmacists in supporting patients can be pivotal. There is an increasing call for medicines information to be embedded in the community and not just confined to a clinician’s room. Pharmacies can provide an ideal environment for patients to have an informal conversation about their medicines without the time pressures that are often associated with appointments with clinicians.
There is huge choice and flexibility for patients, with over 11,500 pharmacies in England(6) hence the potential impact of channelling adherence programmes through pharmacies can make a real difference to non-adherence rates. Internationally, organisation such as the Commonwealth Pharmacy Association are also working to increase access to pharmacy expertise in resource-scarce settings. Moreover, what’s needed by pharmacists to support behaviour changes are not complex or expensive.
Pharmacists can hold more than just the keys to the medicines cabinet, they are experts in medicines and their vital role in the community allows them to advise and support patients in making the most of their medicines.
