Factors influencing the prescribing of medications by old age psychiatrists for behavioural and psychological symptoms of dementia: a qualitative study.

BACKGROUND: despite evidence of limited efficacy, psychotropic medications are widely used as a first line treatment for those with behavioural and psychological symptoms of dementia (BPSD). Clearly various factors must be influencing their continued use; these are explored here. AIMS: to examine the process by which consultant old age psychiatrists prescribe for BPSD and explore the factors that influence their decisions.
METHOD: a focus group generated initial questions for interviews with eight consultant old age psychiatrists, using a grounded theory methodology.
RESULTS: differences in how assessment information was utilised resulted in inconsistencies in choice of medication between psychiatrists. Psychiatrists felt pressured to prescribe, largely due to resource issues and lack of viable alternative treatments.
CONCLUSION: the ways in which psychiatrists prescribe for BPSD varies amongst clinicians. Guidelines do exist, but are difficult to implement in practice. Alternative non-pharmacological strategies are required, but as yet they are difficult to access and have a questionable evidence base.
