Feasibility of a Physical Activity Programme Embedded Into the Daily Lives of Older Adults Living in Nursing Homes: a Randomised Controlled Pilot Feasibility Study

Brief Summary

Detailed Description

Physical inactivity is a global health pandemic and is one of four leading contributors to premature mortality. Although there is evidence that physical activity improves short-term function and is safe among older adults of long-term care, the optimum contents of a physical activity programme or how best to implement it remain unclear. Few studies in nursing homes have attempted to increase physical activity levels by incorporating more usual activities into the resident's everyday routine. The proposed pilot feasibility study will implement a person-centred physical activity programme into the participant's daily routine, based on increasing duration and repetitions of everyday functions including walking and rising from a chair. It incorporates key constructs of social cognitive theory and is monitored by nursing home staff who will receive training and support. Research questions: This pilot feasibility study will have the following primary research questions: 1. Is the intervention feasible and acceptable to staff and participants? * Is the time commitment required for staff to monitor the intervention and participants to partake in the intervention feasible? * Are there any environmental barriers to completion of the intervention? * Is the content of the intervention acceptable to participants and staff? * Do the participants adhere to the intervention and what adherence issues arise? 2. Are the outcome measures feasible and acceptable to participants? * What is the required time and number of visits required to collect each outcome from participants? * Are the outcome measures acceptable to participants? * What is the level of missing data within the self-reported outcome measures? 3. What is the required sample size for a definitive randomised? * What is the baseline score and variability of the primary outcome measure among participants? * What is the estimated effect size and variance for the primary outcome measure? * What are the recruitment and attrition rates for nursing homes and participants? Do these rates differ between the intervention and control groups? The secondary research questions of the pilot study are: 4. What are the preliminary clinical outcomes and cost-effectiveness of the intervention compared to the control group? * What are the components of usual care for participants allocated to the control group? * What are the estimated outcomes of the intervention in comparison with the control group and are these sustained at 12 month follow-up? * What are the costs of the intervention in comparison to costs in the control group? * What is the feasibility of collecting health economic data (i.e. sources used and time taken)? Design: A randomised controlled pilot feasibility study, including a qualitative and economic component will be carried out. Two randomly selected nursing homes will take part in the study; participants (n=20) in one nursing home will receive the physical activity intervention and participants (n=20) in the other will receive usual care. In order to avoid contamination between intervention and control groups, randomisation will take place at nursing home level. The pilot feasibility study will not be an exact scale model of a definitive RCT, the difference being that outcome assessment will not be blinded as a full analysis of outcome data is not intended. However, the recruitment, randomisation, assessment and intervention conditions will be similar to a definitive RCT in order to answer the feasibility research questions. Quantitative outcome data will be collected in an unblinded manner from participants at T1 (baseline, pre-intervention), T2 (directly after completion of the intervention at 4 months) to examine the immediate intervention outcomes and T3 (12 months following the start of the intervention) to examine if the outcomes are sustained beyond intervention completion. Qualitative component: A qualitative descriptive approach will be taken for the qualitative component of the study. Qualitative data will be collected from participants and staff of the intervention group within 1 month following intervention completion and again with the participants at 7 months following intervention completion. Data will be collected via audio-recorded semi structured one-to-one interviews. The aim of the interviews with participants will be to explore the participant's experiences of receiving the intervention, the feasibility and acceptability of the intervention, the perceived effects of the intervention, including potential adverse effect, and issues around maintenance of the participants' physical activity over time, following intervention completion. The staff interviews will explore the staffs' role and experiences of being involved in the study, including their participation in the staff education sessions and the delivery of the physical activity programmes. Semi-structured qualitative interviews will be conducted with small subset of participants from the control group on two occasions. The first interviews will take place immediately following the recruitment and consent stage of the study, in order to maximise the feasibility data obtained for these study processes. The second interviews will take place upon completion of the 4 month intervention with the objective being to define and describe usual care. Economic component: A preliminary estimate of the costs and outcomes of the intervention relative to the usual care control will be assessed using a cost effectiveness analysis and cost utility analysis. Resource use associated with delivery of the physical activity intervention will be measured and costed. Resources used by participants over the course of the study will be recorded in both groups, for example health service usage, medication usage and private expenses relating to the intervention. Data collected from the primary outcome measure, the Timed Up and Go test, at each time point will be used alongside resource usage to provide the basis for the cost effectiveness analysis. For the cost utility analysis, effectiveness will be evaluated on the basis of the Quality Adjusted Life Year which will be estimated using the EuroQol 5 Dimensions 5 Levels instrument, assessed at baseline, 4 month and 12 month follow-up. Statistical analysis: SPSS Statistics (24.0 for Windows, Chicago, USA) will be use to analyse quantitative data. Demographical information in both groups will be tabulated and summarised. The effect of the intervention on clinical outcomes will be examined using suitable numerical and graphical summaries. The statistical analysis will serve primarily to provide an estimation of likely effect size and variance of effect size rather than statistical significance. Qualitative data will be analysed using NVivo (QSR International Pty Ltd. Version 11, 2015). Interviews will be transcribed verbatim and analysed using thematic analysis.
