The feasibility of a pragmatic distance-based intervention to increase physical activity in lung cancer survivors

The purpose of this study was to investigate the feasibility and preliminary efficacy of a pragmatic distance-based intervention designed to increase physical activity (PA) participation in lung cancer survivors. Fourteen lung cancer survivors were recruited via invitation from the State Cancer Registry to join a 12-week PA intervention of print materials paired with brief telephone follow-up. Outcome measures of feasibility, PA participation and quality of life (QoL) were assessed at baseline, post-intervention and follow-up via telephone interview. Eligibility, recruitment and attrition rates were 16%, 58% and 29% respectively. No adverse events were reported; however, pain scores worsened following the intervention (median change -3.6, IQR -8.0, 0.0). Average intervention adherence was 91% with low median ratings of participation burden (i.e., all items 1/7) and high trial evaluation (i.e., all items 7/7). Post-intervention, median change in self-reported moderate and vigorous PA was 84 min (IQR -22, 188), and several domains of QoL improved. However, for both of these outcomes, improvements were not maintained at follow-up. Our findings suggest that this pragmatic distance-based intervention was safe, had good adherence rates, and indicate potential for improving short-term PA and QoL in lung cancer survivors. Additional strategies are needed to improve other indicators of feasibility, particularly recruitment, retention and long-term maintenance of improvements.
