Purpose - The purpose of this paper is to raise issues around the involvement of clinicians relevant to current policies for integrated care by reviewing a previous policy to integrate assessments. Design/methodology/approach - This paper is a review of data from a survey of specialist clinicians' involvement in the single assessment process for older people. Findings - The paper finds that clinician involvement was limited, with assessments not changing to a discernable degree and little involvement of older people. Changes to assessment were predominantly related to paperwork. However, the use of standardised tools by clinicians did increase. The use of shared record systems with social services was significantly associated with involvement. Practical implications - Clinicians have previously not been engaged in policies around integrated assessments. Factors that can help engagement include development of a shared vision, drawing on the traditions of particular groups of clinicians in informing integrated assessment policies, and appropriate IT systems to promote information sharing. Factors hindering engagement include national policy implementation, viewed as inimical to clinical practice and low involvement by service users/patients. Originality/value - Reviewing such previously implemented polices around integration, particularly at the assessment stage, offers lessons to learn in terms of the factors that may help or hinder the achievement of integrated practice, particularly regarding current policies around clinical leadership.
