简要总结
Background: There is a need for standardized interventions in community rehabilitation that can improve everyday task performance for older adults with cognitive challenges after acquired brain injury. Older adults are often excluded from research due to strict inclusion criteria. It is critical for a sustainable health service system that these patients are empowered and reach their maximum level of independence. The Perceive, Recall, Plan and Perform System (PRPP) of Intervention can be applied by Occupational Therapists (OT) for clients with cognitive challenges to enhance mastery of needed or desired everyday tasks. There is no current evidence for the effectiveness of this intervention for this population.
Purpose: A clinical trial to investigate the effectiveness of the PRPP intervention for older persons with cognitive impairments after brain injury in the context of community-based rehabilitation.
Method: In PRPP intervention the OT uses systematically instructions in task training to support a client to use cognitive strategies efficiently. The everyday tasks used for training should be valued by the participant and useful in their rehabilitation. The tasks could include different parts of morning routines, simple or complex meal planning or preparation, use of cell phone, leisure activities, or other household and community activities. At best the skills are generalized throughout all everyday activities, and the OTs' role as a cognitive mediator fades as participants internalize the strategies. The participants receive PRPP intervention 3 times a week for 3 weeks, every session last for 45-60 minutes.
The participants' task mastery and cognitive strategy use will be measured at least 5 times in each phase: baseline, intervention, after the intervention, and 4 weeks after the discharge from rehabilitation. The measurement scores at baseline act controls and are therefore compared with the other phases for the same participant. The same procedure will be repeated for the other participants, but then with a staggered intervention phase. A staggered intervention phase acts as a control between participants and allows to see if changes occur only when the intervention is introduced.
Implications for practice: The investigators assume that this systematic intervention will improve everyday task performance, and will in turn contribute to empowerment and independence of older adults with cognitive challenges after brain injuries.

盲法说明
Participants are randomized to three different baseline-lengths in each tier, that serve as control data in this design. Blinding is not possible for the conducting OT, but an independent PRPP-trained OT assesses 20 % of the PRPP stage 1 and 2 measurements from each phase by videotaping the assessment situations. The tapes will be presented blinded and randomly for this second and blinded assessor.

结局指标
主要结局
Change in task performance
时间窗: Is measured at 5 points in each of the 4 phases; in the baseline phase of the 3, 5 or 7 first days after referral to OT, during 3 weeks of intervention phase, the 2 following days as post-intervention, and 4 weeks after discharge to home.
Five everyday tasks will be target behavior, and each will be divided into a series of significant steps and measured in percentage mastery of the steps according to "The Perceive, Recall, Plan and Perform Assessment stage 1" as a functional measure. The highest score is 100% mastery of the steps, and the lowest is 0%, where none of the steps have appropriate mastery. With a score above 85% the participant is considered as independent, but with minor errors in performance.
