Study Overview
Brief Summary
The objective is to understand and evaluate the effectiveness of a deprescribing intervention in primary care, specifically targeting medications for overactive bladder in individuals aged 65 or older.
Detailed Description
Potentially inappropriate medication is prescribed medications with an unfavorable risk-benefit profile, for which there might be better, safer, or more cost-effective alternatives. Anticholinergic drugs for Overactive Bladder (OAB) is an example of a potentially inappropriate medication in the elderly, calling for attention and possible deprescribing. Due to their crucial role in maintaining a patient's medication regimen, primary care settings are widely regarded as the optimal location for conducting medication reviews and deprescribing interventions.
This study utilizes a mixed methods explanatory sequential design, nested in a randomised controlled trial to explore deprescribing drugs for Overactive Bladder (OAB). General practices will be randomized into two groups. The intervention group will then be evaluated in a mixed methods setup and finish the study with a comparison to the control group. The mixed methods approach employs a quantitative approach following the intervention group and investigates the prevalence of deprescribing the drugs in question. Secondly, a qualitative approach will be used to delve into the experiences of general practitioners (GPs), support staff, and patients during the deprescribing process. Finally, the quantitative and qualitative findings are merged to gain a comprehensive understanding of deprescribing for OAB. This integrated approach enhances insights and informs future interventions and recommendations. After the mixed methods studies are completed the control group will be used in an overall comparison of the two groups using registry data

Arms & Interventions
Intervention group
The primary care clinics in the intervention group will contact and evaluate all patients receiving one or more of the following drugs:
G04BD04 Oxybutynin G04BD07 Tolterodine G04BD08 Solifenacin G04BD09 Trospium G04BD10 Darifenacine G04BD11 Fesoterodine G04BD12 Mirabegron The patients will be asked to discontinue the treatment and eventually be deprescribed
Intervention: deprescribing-intervention (Other)
Control group
The primary care clinics in the control group will not contact and evaluate patients and are not informed about the study. Data will be extracted from registries
Outcomes
Primary Outcomes
Difference in proportion of patients receiving drugs for overactive bladder
Time Frame: 6 months
The primary outcome will be the difference in the proportion of patients receiving drugs for overactive bladder before and after a 6-month follow-up period.
Secondary Outcomes
- Changes and distribution of bladder symptoms(6 months)
- The proportion of patients where deprescribing was not initiated(6 months)
- proportion of patients in the intervention group who had deprescribing initiated but not sustained(6 months)
