Overall, there was confusion about how decisions were made about the acceptance of referrals and the resources allocated to a case. Concern was expressed for those children whose parents were not able to pursue issues of perceived deficiencies in care. Models of provision: ongoing versus episodic care Some parents reported experiences of repeated cycles of time-limited provision, discharge and re-referral. Parents consistently favoured arrangements that allowed ongoing access to therapy support, ideally from the same therapist. When parents felt that their child did not need continual input, open discharge arrangements (i. The key difficulty parents identified with episodic care was the lack of continuity of care. For example, one parent reported that her child had been seen by 12 occupational therapists. Another mentioned that seven physiotherapists had been involved with her child. This lack of continuity was viewed as problematic for two reasons. Second, some parents believed that it led to therapists having an incomplete understanding of conditions or diagnoses, in particular that the conditions are lifelong with changing needs. Integrated care A dominant theme in our conversations with parents was the integration of provision from the three therapies. The majority reported that they did not experience this. They were not aware of any joint or integrated assessment, outcomes/goals-setting, and therapy delivery between physiotherapy, occupational therapy and speech and language therapy. Parents reported that this left them, and school staff, confused about the correct approaches to supporting and working with the child. This situation could also leave parents feeling overburdened about what they were expected to do with their child in terms of delivering the therapy programmes set out by the therapist. Parents with experience of specialist independent education provision (with places purchased by local authorities) noted that this seemed to be the only setting in which a true integration of therapies was achieved. This was because the therapists were core members of staff and always on site. Parents also explored notions of integration in terms of the position of therapy provision with respect to the wider care and management of their children. They spoke positively about child development centres, believing that these supported integrated working owing to the co-location of professionals and joint working practices. Less positive were experiences of Education, Health and Care Plans, which are part of statutory assessment and planning processes for children with additional needs over and above those provided within usual special educational needs support,26 as these had not always led to co-ordinated approaches to therapy provision and interventions. We describe in a later section their experiences of assuming this role. More generally, parents spoke of how they knew their child best, including their strengths and weaknesses. Related to this was a desire for a greater sense of working in partnership. In contrast, parents believed that partnership working benefited the child. Parents also regarded themselves as advocates for their child. This was represented in their desire to be actively involved in assessment and planning processes, seeking the best for their child and speaking on their behalf.
