Evaluation of costs
The practitioners in this study were primarily OTs employed in the NHS on a standard pay and grading structure. We calculated the per-person cost of NHS OTs delivering a course of GREAT CR consisting of six one-hour sessions under our implementation strategy. As we observed different combinations of input by qualified OTs and OT support workers we calculated costs for four skill-mix scenarios. As the time and costs of travel to conduct home visits are likely to differ locally, we present results both including and excluding travel costs. The scenarios, assumptions, calculation of unit costs and cost estimates are summarised in Table Per-person cost estimates for a six-session course of CR under four staff skill-mix scenarios1, A qualified OT provides all 6 sessions2. A qualified OT provides the first and last sessions and an OT support worker provides the intervening 4 sessions3. A qualified OT and an OT support worker jointly provide the first and last sessions and the OT support worker provides the intervening 4 sessions4. A qualified OT and OT support worker jointly provide the first session and the OT support worker provides the remaining 5 sessionsQualified OTs are on NHS Agenda for Change Band 6 (‘Occupational therapist specialist’) [Unqualified OT support workers^ are either OT Assistants on Band 3 (‘Clinical support worker, higher level, OT’) or OT Technicians on Band 4 (‘OT technician’) [YearHour77 19948.32YearHour50 65931.27YearHour38 72025.02National Health Service, NHS; Occupational Therapist, OTOccupational Therapist, OT; OT Technician, OT Tech; Personal Social Services Research Unit, Unit Costs, PSSRU UCOccupational Therapist, OT
