### Adherence of Participants to Using Global Positioning Systemsand Fitness Tracking Technology  
Downloaded activity and GPS data was used to measure adherence by evaluating missing data, gaps in recording and periods of non-activity. All except one participant maintained (charged) the phones and ensured data transmission. Consequently, at completion of the study, 18 (94%) participants had provided 30 days of tracking data and 15 (83%) participants had provided 90 days of tracking data. Compare the 30-Day and 90-Day Post-Discharge Activity Levels between Those Who Lived in Metropolitan Areas with Those Who Live in Rural Areas  
Total physical activity recorded for all participants in the was a median of 2506 (standard deviation (SD) \(\pm\) 369) steps per day in the first 30 days, slightly higher for metro participants (median 3543 (SD \(\pm\) 826) steps) and slightly less for rural participants (median 1987 (SD \(\pm\) 141) steps). Two thousand five hundred steps per day was the equivalent of 20 min of walking or approximately 1.5 km (Figure 2). \begin{table}

Table 2: Demographics, clinical characteristics and risk factors of participants. There was an overall 10% increase in physical activity in the next 30 days, but this was not sustained. By 90-days post-discharge the total physical activity as measured by steps-per-day had significantly decreased (_p_ < 0.05) by 33% to 1686 (\(\pm\)128) steps per day (metro \(\downarrow\) 22% 2777 (\(\pm\)177) steps vs. rural and remote \(\downarrow\) 35% 1290 (\(\pm\)172) steps). There was one rural outlier who completed 10,000 steps per day from seven days post-discharge. One of these daily walks demonstrating the maps produced by the GoogleFit(tm) app is presented in Figure 3.
