Summary

This is a pilot study intended to gather data in order to inform future studies about the role of feedback as an incentive for increasing levels of physical activity which could improve health in hemodialysis patients.

Detailed description

In prior studies that have analyzed physical activity in dialysis patients, three-dimensional accelerometers, physical performance tasks or self-reporting physical activity questionnaires have been used to measure levels of activity. This proposed study differs in that it will determine the effectiveness of providing "feedback" to dialysis patients using a fitness tracking bracelet. For the purpose of this study, the word 'feedback' is used to refer to the information provided to the subject that demonstrates the number of steps taken since the previous dialysis session as displayed by the Fitbit® application. This 'feedback' will allow subjects to be more aware of their overall physical activity on a quantitative level. The study will seek to explore an association between feedback and physical activity. Improved physical activity could improve indicators of subjects' health status such as blood pressure, inflammatory markers, and pre-albumin levels, which will also be monitored and recorded. While informing subjects quantitatively about their levels of physical activity could be a promising method to encourage them to be more active, it is unclear at this point if that strategy actually works. This is an important practical question though, because actually informing subjects on a regular basis about their activity level may pose substantial operative challenges and result in additional costs. The importance of encouraging subjects to be more physically active should not be underestimated. Studying the physical activity of dialysis patients is important because it allows researchers to consider the long-term effects that may influence the subject's well-being. Johansen et al. showed that there was a direct relationship between the inactivity of dialysis patients and susceptibility to hypertension, diabetes, cardiovascular disease and even mortality. Additionally, the study demonstrated the importance of implementing programs to promote physical activity \[1\]. If feedback does indeed increase physical activity, then it will be substantially beneficial for this program to be implemented.
