Table 1: Outline of method for developing the blueprint for a Brain Health Clinic.

Project timeline:

• November 2018, project launch and work-groups form

• March 2019, first full group videoconference

• April - August 2019, follow-up full group videoconference

• September - December 2019, iterative development and pilot testing of the tool

• February 2020, launch of Brain Health Clinic blueprint on-line tool

Setting and procedures:

· Baseline clinical audit of three representative Memory Assessment Services in Manchester, UK to describe current clinical practice

· Initial contact with professional stakeholders via a two-day Dementia Academy clinical masterclass hosted by Neurology Academy (www.neurologyacademy.org), Sheffield, UK (11/2018) to form a project task force

· Project orientation session introducing aims, method and timeline

· Five delegate workgroups formed; each assigned a sub-section of the tool

· Workgroup video-linked meeting every two months to draft the blueprint

· Fourth draft presented for consultation to new delegates of Dementia Academy masterclass, Sheffield, UK, June 2019

· Sixth and seventh iterations developed by the workgroup

· Final version launched on-line, February 2020

Task force participants

Delegates attending the Dementia Academy masterclass were 32 practicing clinicians with the following backgrounds:

· geriatric psychiatry (n = 1)

· geriatrics or medicine for the elderly (n = 15)

· specialist registrars (senior clinical trainees) in geriatrics, neurology and geriatric psychiatry (n = 5)

· orthogeriatrics (n = 1)

· mental health nursing (n = 1)

· neuroscience nursing (n = 4)

· general practice (n = 2)

· neuroradiology (n = 1)

· clinical research in ageing (n = 1)

Facilitators:

· The project lead and Dementia Academy director (IL) facilitated the group sessions and video-linked meetings

· Each workgroup was facilitated by a Dementia Academy faculty member

· Each workgroup appointed a designated lead to coordinate work

Data collected to develop the blueprint for the Brain Health Clinic:

· Stage 1: Audit of MCI diagnosis and patient journey in NHS UK MAS’s (11)

· Stage 2: Expert consultation, divided into five work workgroups to develop the components of the BHC:

· Aim and ethos of the BHC

· Characteristics of the typical BHC attendee

· Steps in a diagnostic work-up to establish a meaningful diagnosis of prodromal dementia, including the sub-type, and risk stratification

· Types of interventions (pharmacological and non-pharmacological) and the infrastructure to support them

· Patient journey through and beyond the BHC

· Stage 3: Consultation with experts of the draft tool

· Stage 4: On-line launch of the tool, Blueprint for a BHC
