The feasibility of a pragmatic distance-based intervention to increase physical activity in lung cancer survivors (#306)
Aims
To investigate the feasibility and preliminary efficacy of a pragmatic distance-based intervention designed to increase moderate intensity physical activity participation in lung cancer survivors.
Methods
Lung cancer survivors (stage I-IIIB non-small cell lung cancer) were recruited via invitation from the state Cancer Registry to join a physical activity intervention. At baseline participants received a personalized folder with a physical activity logbook. Over the 12-week intervention participants received eight mail-outs of print material with brief telephone follow-up. Each scripted call was tailored to compliment the print-materials. Questionnaire assessments were administered via telephone at baseline and post-intervention. Primary outcomes measured feasibility: eligibility and recruitment rate, loss to follow-up, adherence to telephone follow-up, ratings of participation burden and trial evaluation. Secondary outcomes measured changes in physical activity (Godin Leisure-Time Exercise Questionnaire), quality of life (QoL; SF-36, FACT-L), and dyspnea (Cancer Dyspnea Scale). The Wilcoxon Signed Rank Test was used to assess changes over time.
Results
128 lung cancer survivors were screened, 29 were eligible (23%) and 14 recruited (43%), of which 50% lived in rural Western Australia. Eleven participants (79%) completed the entire intervention; ten (71%) completed the post-intervention assessment. Mean adherence to telephone follow-up was 90%. For those completing post-testing, mean ratings of participation burden were low (i.e., all items <3/7), and trial evaluations were high (i.e., all items >6/7). Post-intervention there was a non-significant mean improvement of 77 minutes per week of moderate intensity physical activity (p=0.279). Dyspnea discomfort was significantly reduced following the intervention (p=0.042). Several domains of QoL significantly improved including general health (p=0.007), emotional well-being (p=0.042), and lung cancer concerns (p=0.011).
Conclusion
This pragmatic distance-based intervention had a high adherence rate and was reviewed favourably by participants. The post-intervention improvements in physical activity participation, quality of life, and dyspnea are likely meaningful for lung cancer survivors.
