About the tool
This clinical tool aims to help family physicians and primary care nurse practitioners manage ADHD in adult patients. It is designed to guide discussions and decision-making between clinicians and their patients in managing ADHD.
The ADHD in Adults tool was developed using CEP’s integrated knowledge translation approach. This approach ensures that clinicians are engaged throughout the development processes through the application of user-centred design methodology. Clinical leadership was provided by Dr. Devon Shewfelt. Persons with lived experience and end users were also engaged throughout the tool development process to provide feedback and support the tool’s refinement.
The tool is among several clinical tools developed as part of the Knowledge Translation in Primary Care Initiative. Funded by the Ministry of Health, this initiative supports primary care clinicians with the development of a series of clinical tools and health information resources.
