The West Wales ADR Profiles for medicines' monitoring have improved quality of care by reducing the prescription of mental health medicines and identifying and addressing previously unsuspected adverse effects, such as coupled beats and severe hypertension (Jordan 2002, et al 2002), infections (Gabe el al 2014), chest pain and valproate-induced pancreatitis (Jones et al 2016), and, in care homes, drug-induced Parkinson's (Jordan et al 2014), pain, nausea and behaviour problems (Jordan et al 2015). The investigators now need to know how the intervention can embed in practice and governance frameworks, and benefit from pharmacist involvement and new monitoring devices.
