摘要
It is known that for all adults, prevalence of potentially inappropriate prescribing (PIP) and polypharmacy increases with advancing age and morbidity. This has been associated with adverse drug reactions and poor outcomes. As a result, screening tools have been developed to identify PIP and to improve prescribing and health outcomes. A growing body of evidence supports the fact that there are even greater concerns among older adults with intellectual disability (ID) who are living longer than before but still have premature mortality and poorer health outcomes compared with the general population. They have different patterns of multimorbidity, with higher rates of epilepsy and mental health conditions. Polypharmacy is prevalent and some prescribing practices may be inappropriate. High exposure to anticholinergic and sedative medicines has additional adverse effects on quality of life. There may also be underutilization of clinically needed therapies. There has been substantial controversy internationally relating to extensive use of psychotropic medicines, particularly off-label use for challenging behaviours. Despite the mounting evidence and concerns about the impact of PIP on quality of life, health and safety for people with ID, appropriate methods to measure PIP are lacking, which represents an important gap in the research literature. Differences in morbidity and medicines use patterns in this population mean instruments used to identify inappropriate medicines in the older population are not suitable. In this perspective article we outline the specific health and medicinal needs for people with ID, the prevalence of polypharmacy and presentation of chronic health conditions in older adults with ID. We provide an overview of the psychotropic medicine classes most frequently used in people with ID which carry substantial risk. We highlight studies to date that have attempted to assess PIP and present research priorities to improve prescribing, health outcomes and quality of life for people with ID.
