PURPOSE

Metastatic breast cancer (MBC) patients are living longer at the cost of several side effects, affecting their physical and mental health. Physical activity can help women with MBC to improve their wellbeing. Technology-based exercise interventions have shown promising outcomes; however, studies that document their benefits on health behaviors are lacking. Therefore, we aimed to document the impact of virtual assistant technology on enhancing daily step counts in women with MBC.

METHODS

A total of 38 women with MBC participated in the 90-day Nurse AMIE (Addressing Metastatic Individuals Everyday) for Amazon Echo Show study, an artificial intelligence-based supportive care intervention. Each day, Nurse AMIE asked four symptom questions (sleep, pain, fatigue, and distress) and daily step counts. Based on participants' answers, an algorithm provided an activity to assist with symptom management.

RESULTS

During the first week of the intervention, mean step counts per day were 4935 ± 2884, and during the last week of the intervention, mean step counts per day were 1044 steps higher, for an average of 5979 ± 2651 steps. Non-significant differences were observed between the first and last week (p = 0.211) and between the first and last day (p = 0.099), despite an improvement of 21.2% over time and significant differences between baseline and the other days.

CONCLUSION

Women with MBC benefited from the Nurse AMIE for Amazon Echo Show intervention. Despite improvements over time (> 20%), we cannot conclude that the intervention significantly enhanced participants' daily step counts. Larger studies using virtual assistant technologies are required, and this study should be considered a first step in this direction.
