Description of intervention(s) / exposure
Current measures of cognition utilised in rehabilitation are valuable diagnostically but often do not fully address the functional implications of cognitive deficits. One primary concern at discharge from hospital is predicting the ability of a patient to function independently or to estimate the degree of assistance required to do so. The focus of this study is on the use of the Kettle Test as a quick performance measure that is based on a complex everyday task and is designed to tap into basic and higher-level cognitive processes to predict cognitive function.

Patients participating in sub-acute rehabilitation in a tertiary hospital routinely participate in an Mini Mental State Examination (MMSE) and Cognitive Functional Independence Measure (FIM) assessment at admission and discharge. Following consent a participant will complete the Kettle Test with an Occupational Therapist in the hospital environment. This will be completed on admission and discharge. The Kettle Test will involve a 20-30 minute assessment at admission and discharge.

The motor subscale of the Functional Independence Measure (mFIM) will be used to assess functional status and improvement. Patients will be evaluated at admission and discharge by the rehabilitation team.

The mFIM will be used to examine functional outcomes because this score isolates functional activities from cognitive ratings, which are combined in the total FIM score. A Daily Living Self-Efficacy Scale will be completed on discharge to review a participant’s confidence about returning home by the Occupational Therapist.

Participants would receive a phone call within their first week post discharge to review their functional status (via the mFIM), management at home, caregiver support, community service use and representation rates. This telephone call will consist of a series of question and will be completed by an Occupational Therapist.

The participants would receive an additional phone call from an Occupational Therapist at one month post discharge to review functional status (via the mFIM), management at home, caregiver support, community service use, representation rates, medical status and deaths. We will also collect data concerning age, gender, length of rehabilitation stay (LOS) and diagnoses.

Statistical methods / analysis
Sample size adequacy was determined by the guidelines set by Bland and Altman1, where the standard error of the within-subject standard deviation (sw), is shown to depend on both number of subjects (n), and number of observations per subject (m). The 95% confidence interval (CI) for sw is determined to be sw +/ 1.96sw/v(2n(m-1). With 3 repetitions (m = 3), and requiring that the width of this interval is no more than +/- 0.1sw (so that we are confident that we know sw within 10%), the minimum sample size required to assess the agreement between Kettle, Mini Mental Status Examination and Cognitive FIM is 97.

Summary statistics, frequencies and descriptive plots will be used where appropriate. Intra-class correlations and Bland Altman plots will be used to assess the agreement between Mini Mental Status Examination, Cognitive FIM and Kettle cognitive test scores (standardisation techniques may be used). Linear mixed models will be used to assess the relationship between change in functional (FIM) and cognitive (Mini Mental Status Examination, Cognitive FIM and Kettle) scores.

Summary
Brief summary
Current measures of cognition utilised in rehabilitation are valuable diagnostically but often do not fully address the functional implications of cognitive deficits. One primary concern at discharge from hospital is predicting the ability of a patient to function independently or to estimate the degree of assistance required to do so. The focus of this study is on the use of the Kettle Test as a quick performance measure that is based on a complex everyday task and is designed to tap into basic and higher-level cognitive processes to predict cognitive function.

The participant group would be recruited from patients participating in rehabilitation at the Sir Charles Gairdner Hospital (SCGH), Geriatric Evaluation and Management Unit (GEM). The study design is a Prospective Cohort Study. The Mini Mental Status Examination (MMSE) and Cognitive FIM Instrument are cognitive assessment tools currently used with inpatients on GEM. They are standardised tools involving a series of questions and paper based assessments.

The Kettle Test is a new cognitive assessment tool, which utilises a functional task. We wish to assess the Kettle Tests accuracy in detecting cognitive impairment, when compared to traditionally used assessment tools. Also we will assess all tools capacity to predict a patient’s functional capacity. Functional capacity will be measured via the motor component of the Functional Independence Measure (mFIM).

The study also includes questions from a Daily Living Self-Efficacy Scale to assess the level of individual’s belief in their functional abilities and confidence to return home.

Participants or their caregivers would receive a phone call within their first week post discharge to review their functional status (via the mFIM), management at home, caregiver support, community service use and representation rates.

The participants would receive an additional phone call at one month post discharge to review functional status (via the mFIM), management at home, caregiver support, community service use, representation rates, medical status and deaths. We will also collect data concerning age, gender, length of rehabilitation stay (LOS) and diagnoses.

It is anticipated that the Kettle Test will accurately detect cognitive functional deficits in adults with suspected cognitive impairments, and that the Kettle test will give clear and specific information about the functional abilities and impairments of the patient once discharged to the home environment.
