The Home-Heart-Walk study, a self-administered walk test on perceived physical functioning, and self-care behaviour...

Adherence to self-care recommendations is associated with improved patient outcomes and improved quality of life for people living with heart failure. The Home-Heart-Walk (HHW) is an intervention to promote physical activity adapting the elements of a six minute walk test, a reliable and valid measure. This adaptation was designed to support self-monitoring of physical functioning and promote the self-care of people with heart failure. The primary outcome of the Home-Heart-Walk was perceived physical functioning and the secondary outcomes were six-minute walk test distance, health related quality of life, self-care behaviour, self-efficacy and physical activity level.

A multicentre randomized controlled trial. Participants ( N=132) were recruited from three academic hospitals in Sydney, Australia. Participants were randomized to either the Home-Heart-Walk group or the control group. Perceived physical functioning, health related quality of life, self-care behaviour, exercise self-efficacy and physical activity level were measured at baseline and at three- and six-month follow-up.

After adjusting for baseline scores, there were no statistically significant between-group differences in perceived physical functioning, six-minute walk test distance, health related quality of life and exercise self-efficacy at follow-up. The intervention group had improvement in self-care behaviour ( F(1,129) = 4.75, p = 0.031) and physical activity level ( U = 1713, z = -2.12, p = 0.034) at the six-month follow-up compared with the control group.

The Home-Heart-Walk did not improve the perceived physical functioning of the intervention group. Although the feasibility and acceptability of this strategy to support self-monitoring and improve self-care behaviour was demonstrated, self-reported adherence was unreliable; newer technologies may offer better assessment of adherence.
