Target numbers of sit to stands.

Older adults with cognitive impairment often experience low mobility and functional decline in hospital, transfer to facility-based transitional care programs, and have poorer outcomes compared to those without cognitive impairment. This protocol paper describes a study which aims to determine the feasibility of, satisfaction with, and efficacy of a nurse-led mobility intervention (OASIS Walking Intervention) for older adults with cognitive impairment in facility-based transitional care programs in Ontario, Canada. A quasi-experimental one-group time series feasibility study will be conducted. A sample size of 26 participants will be recruited from two transitional care programs in Ontario, Canada. Participants will receive the OASIS Walking Intervention for up to 45 minutes per session, 5 sessions per week, for 6 weeks. The intervention consists of: 1) a patient-centered communication care plan; 2) sit to stand activity; and 3) a walking program. Feasibility will be determined by: a) recruitment rate; b) retention rate; and c) adherence. Efficacy of the intervention will be determined by the change over time in older adults’ lower extremity muscle strength, mobility, and functional status and by their discharge destination (home vs. nursing home). Satisfaction will be measured using the Client Satisfaction Questionnaire. Efficacy outcomes will be measured before the start of the intervention, after 3 weeks of the intervention, and immediately after 6-week intervention. Descriptive statistics will be used for measures of feasibility, satisfaction, and discharge destination. Repeated measures analysis of variance (RM-ANOVA) will be used to analyze efficacy. Ethics approval has been received for this study. Findings from the study will be used to refine the intervention for use in a definitive pilot trial. Results will be disseminated via peer-reviewed publications, international conferences, through group presentations at the study sites, and through the study site networks.
Trial registration: The trial has been registered on Clinicaltrials.gov (NCT06150339).

认知障碍老年患者在住院期间常出现运动能力低下与功能衰退，转入机构式过渡照护项目后，相较于无认知障碍患者，其临床预后更差。本方案论文介绍一项研究，旨在评估加拿大安大略省机构式过渡照护项目中，针对认知障碍老年患者的护士主导运动干预——OASIS步行干预（OASIS Walking Intervention）的可行性、受试者满意度与干预有效性。

本研究采用类实验性单组时间序列可行性研究设计。计划从加拿大安大略省的两家过渡照护项目中招募26名受试者。受试者将接受OASIS步行干预，每次干预时长不超过45分钟，每周开展5次干预，持续6周。该干预方案包含三部分：1）以患者为中心的沟通照护计划；2）坐站训练活动；3）步行训练计划。

可行性将通过以下三项指标评估：a）招募率；b）保留率；c）干预依从性。干预有效性将通过老年患者下肢肌肉力量、运动能力与功能状态随时间的变化情况，以及其出院去向（居家 vs. 养老院）进行评估。受试者满意度将采用患者满意度问卷进行测量。

有效性结局指标将分别在干预开始前、干预3周后及6周干预结束后即刻完成测量。可行性、满意度与出院去向的评估将采用描述性统计方法。重复测量方差分析（Repeated Measures Analysis of Variance, RM-ANOVA）将用于有效性数据的统计分析。本研究已获得伦理审查批准。

本研究的结果将用于优化该干预方案，以支持后续的确定性预试验。研究成果将通过同行评议期刊、国际学术会议、研究场地的小组汇报以及研究场地合作网络进行传播。
