We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Older adults admitted to the acute aged care ward at the Prince of Wales Hospital due to sustaining a fall will be recruited for this study. Once consent has been provided, participants will complete two functional outcome measures: Timed Up and Go (TUG) test (assesses functional mobility, balance, and fall risk in older adults), and Short Physical Performance Battery (SPPB) (assess lower extremity function, mobility, and physical performance in older adults). The outcome measures will be completed within 72 hours of admission to the acute ward, and then again prior to discharge from the ward by their treating physiotherapist.

Once the initial outcome measures are completed, participants will be observed across a two-day period (one weekday and one day over the weekend) every 10 minutes from 8am to 5pm. The days of the week will be randomly selected from the six days following completion of consent and functional outcome measures. Participants are not required to interact with the research team during the observation sessions. They will be aware and consent to being observed on two days between 8am and 5pm during their admission to the acute aged care ward, but will not be informed of which actual days the observations will take place.

Statistical methods / analysis
Sample size calculation
Sample size (n=50) was determined using Ausvet’s Epitools sample size calculation for estimating a single mean. An assumed population SD of 18 (based on a previous, similar study), Confidence Interval (CI) of 0.95, and desired precision of 5 were used to determine the study’s target sample size. This is larger than previous research, which had a mean sample size of 35 participants, accommodating for potential attrition during the study.

Analysis plan
Descriptive analyses and regression modelling will be used to quantitatively examine the associations between activity levels and other study variables (sociodemographics, functional ability, mobility status, healthcare services use on discharge, and day of the week). Mean, standard deviation (SD), median, 95% CI, and range of proportion of observations spent in each category, as well as summation of time spent in each category will be calculated. Comparison of activity levels by room size (number of beds) will be analysed using either the independent t-test or Mann-Whitney U test (dependent on data distribution). Comparison of activity levels by day of the week (weekday vs. weekend) will be analysed using either the paired t-test or Wilcoxon paired signed rank test (dependent on data distribution). Statistical significance will be set to p < .05.

Summary
Brief summary
During hospitalisation for an acute illness, an estimated 23% to 33% of older adults experience low mobility. Low levels of activity and older age are predictors of functional deterioration and poor health outcomes during hospitalisation. Yet activity levels of hospitalised older Australians has not been investigated, with previous behaviour mapping research focusing on general rehabilitation and stroke. This project will use behaviour mapping to determine the activity levels of older adults admitted to an acute aged care ward in an Australian hospital due to sustaining a fall, and examine associations between activity levels and health-related variables (e.g. functional ability, community services use, discharge destination). Falls were selected as the condition to focus on among this population as it is one of the most common reasons for admission to hospital among older adults. This project will identify potential and modifiable risk factors that could be addressed to improve patient care and outcomes for older Australians.
