AbstractOlder patients commonly suffer from multimorbidites and take multiple medications. As a result, these patients are more vulnerable to potentially inappropriate prescribing (PIP). PIP in older patients may result in adverse drug events and hospitalisations. However, little has been done to identify why PIP occurs. The objectives of this study were; (1) to identify hospital doctors' perceptions as to why PIP occurs, (2) to identify the barriers to addressing the issues identified, and (3) to determine which intervention types would be best suited to improving prescribing.
Semi-structured interviews based on the Theoretical Domains Framework (TDF), a tool used to apply behaviour change theories, were conducted with 22 hospital doctors. Content analysis was conducted to identify domains of the TDF that could be targeted to improve prescribing for older people. These domains were then mapped to the behaviour change wheel to identify possible intervention types.
Content analysis identified 5 of the 12 domains in the TDF as relevant; (1) environmental context and resources, (2) knowledge, (3) skills, (4) social influences and (5) memory/attention and decision processes. Using the behaviour change wheel, the types of interventions deemed suitable were those based on training and environmental restructuring.
This study show that doctors feel there is insufficient emphasis on geriatric pharmacotherapy in their undergraduate/postgraduate training. An intervention providing supplementary training, with particular emphasis on decision processes and dealing with social influences would be justified. This study has however, uncovered many areas for potential intervention in the future.
