The effectiveness of psychotropic medication on behavioral and psychological symptoms in dementia (BPDS) is limited, while they are associated with a higher risk of morbidity and mortality. Non-pharmacological treatment of BPSD is advocated as treatment of first choice. However, many general practitioners (GPs) find it difficult to initiate deprescribing and when attempting to discontinue psychotropic drugs in nursing home residents, they can face substantial barriers both among nursing home staff and relatives. Therefore, the investigators have developed an intervention specifically aimed at increasing knowledge on deprescribing and improving communication and collaboration between GPs, nursing home staff, relatives and patients to optimize the pharmacological treatment of BPSD.
It is estimated that more than 87.000 in Denmark are living with dementia, with more than 8000 new cases each year. The majority of older persons with dementia are living at home but in a minority problems with daily activities necessitates relocation to a nursing home. Besides cognitive impairment, up to 90 % of the institutionalized older people with dementia may experience behavioral and psychological symptoms of dementia (BPSD) such as anxiety, agitation, hallucinations, depression, and apathy. An overuse of antidepressants is reported and in Denmark, about half of all nursing home residents receive at least one antidepressant and many receive other psychotropic drugs such as antipsychotics, anxiolytics and hypnotics in addition to the antidepressants. However, recent research has shown that the benefits of treatment with antidepressants in patients suffering from dementia are limited while increasing the risk of falls and cardiovascular adverse events in institutionalized older persons. Given the limited effectiveness of psychotropic medication and its high risk of side-effects such as dizziness and falls, the use of antipsychotics and anxiolytics have been recommended against for a long period, while recommendations considering antidepressants have been more mixed. Danish national guidelines recommend against the use of antidepressants in older people suffering from dementia and advocate non-pharmacological treatment of BPSD as treatment of first choice.
However in contradiction with the guidelines, a recent study showed that moving into a nursing homes, was accompanied with an increase in the number of new drug treatments including antidepressants and that this number remained unchanged for at least two years. Studies on the implementation and retention of strategies to discontinuation of psychotropic medication have shown varying effects. A recent qualitative systematic review has shown that discontinuation is often hindered by 1) the GP not getting the necessary information from the staff, 2) both relatives and staff can have concerns about the reduction or discontinuation of psychotropic medication or 3) the GP does not feel sufficiently competent/confident on their knowledge of the medication to make adjustments. These factors complicate the evaluation and adjustment of pharmacological treatment of neuropsychiatric symptoms. A Danish national strategy to try to reduce antipsychotics have been initialized in 2020, but to our knowledge there is no focused initiative to reduce antidepressants.
In Denmark each patient has a General Practitioner (GP), and the majority of nursing homes in the Capital Region has a GP who is affiliated with the nursing home. The patients may choose to accept this GP as their nursing home physician when moving to the nursing home. A nursing home physician helps improve continuity and reduces the risk of hospitalization for the patients when compared to patients without a nursing home physician.
The investigators therefore chose to apply the intervention to the nursing home physicians and their patients since more and more patients are having a nursing home physician and research has shown that is reduces amongst other things, hospitalization. Since the study is a cluster randomized controlled study set place in the Capital Region of Denmark, the investigators first invited nursing home physicians to participate. In order to be included, they had to have at least 10 patients at a nursing home.

The GPs receive a power-point slide show to use at the nursing home. The slide show includes a description of BPSD symptoms, what the mechanism, effect and adverse events of antidepressants and a rationale for deprescribing.
The GPs receive a checklist and an email template to ensure; 1) The home visit is planned on a day where the staff at the nursing home that knows the patient best is at work. 2) The staff at the nursing home contacts the relevant relatives and informs about the home visit. 3) The symptom assessment scale is complete by the nursing home staff and returned to the GP prior to the home visit
The dialogue tool includes a list of questions to help the GP explore the nursing home staffs', patients' and relatives' concerns and views on deprescribing antidepressants, as well as information on when to contact the GP. The intervention has been developed during a tailoring process involving GPs, nursing home staff, interviews with patients and other experts in the field.
Before randomization all participating GPs receive a ½-day course on the evaluation and treatment of neuropsychiatric symptoms that occur in patients with dementia. Elaborate information about antidepressants to this population and reasons to discontinue use. A sSpecialists in general practice, pharmacology and geriatrics/gerontopsychiatrics teaches the course. The course is mandatory for the participating GPs, but voluntary for the staff at the GPs office. The course is preferably held with actual attendance, but may be converted to an online meeting due to the COVID-19 pandemic.
An email template containing 12 screening questions from the Neuropsychiatric Inventory Nursing Home Edition is given to the GPs to distribute to the nursing home prior to the home visit and 1 month after the home visit
Reduction of antidepressant
The primary outcome is any reduction of any antidepressant from pre- to post intervention during the intervention period, in the intervention group compared to the control group, measured as a dichotomized response (reduction; yes/no). In case of reduction of an antidepressant and an addition of another antidepressant this will not be considered a reduction
