Service Development

Hello! I hope that you're able to help me? I'm a clinical specialist occupational therapist working in community mental health in the North East of England. I work across a number of adult mental health teams in a locality which are undergoing redevelopment. As a result, additional funding may be available for OT provision. My issue is, is that we cant find recommendations/national indicators about how many OT's v population/client group is realistic. How have you navigated this or what has been funding/service rational for appropriately meeting the OT need of your client groups, in this case, for EIP. Thank you!
