Development of a tool for monitoring the prescribing of antipsychotic medications to people with dementia in general practice: a modified eDelphi consensus study

Background: Despite their adverse effects, antipsychotics are frequently used to manage behavioral and psychological symptoms of dementia. Regular monitoring of antipsychotic prescribing has been shown to improve the appropriateness of prescribing. However, there is currently no consensus on what the components of such a monitoring tool would be. Aim: The aim of this study was to use an expert consensus process to identify the key components of an antipsychotic repeat prescribing tool for use with people with dementia in a general practice setting. Methods: A modified eDelphi technique was employed. We invited multidisciplinary experts in antipsychotic prescribing to people with dementia to participate. These experts included general practitioners (GPs), geriatricians and old age psychiatrists. The list of statements for round 1 was developed through a review of existing monitoring tools and international best practice guidelines. In the second round of the Delphi, any statement that had not reached consensus in the first round was presented for re-rating, with personalized feedback on the group and the individual's response to the specific statement. The final round consisted of a face-to-face expert meeting to resolve any uncertainties from round 2. Results: A total of 23 items were rated over two eDelphi rounds and one face-to-face consensus meeting to yield a total of 18 endorsed items and five rejected items. The endorsed statements informed the development of a structured, repeat prescribing tool for monitoring antipsychotics in people with dementia in primary care. Conclusion: The development of repeat prescribing tool provides GPs with practical advice that is lacking in current guidelines and will help to support GPs by providing a structured format to use when reviewing antipsychotic prescriptions for people with dementia, ultimately improving patient care. The feasibility and acceptability of the tool now need to be evaluated in clinical practice.
