Web-based physical activity promotion in young people with CF: a randomised controlled trial.

BACKGROUND: Physical activity levels are known to decline following hospitalisation for people with cystic fibrosis (pwCF). However, optimal physical activity promotion strategies are unclear. This study investigated the effect of a web-based application (ActivOnline) in promoting physical activity in young pwCF. METHODS: Multicentre randomised controlled trial with assessor blinding and qualitative evaluation. People with CF (12-35 years) admitted to hospital for a respiratory cause were eligible and randomised to the 12-week ActivOnline intervention (AO) or usual care (UC). The primary outcome was change in device-based time spent in moderate-to-vigorous physical activity (MVPA) from baseline to post-intervention. Follow-up was at 6 months from hospital discharge when qualitative evaluation was undertaken. RESULTS: 107 participants were randomised to AO (n=52) or UC (n=55). Sixty-three participants (59%) contributed to the intention-to-treat analysis. Mean (SD) age was 21 (6) years (n=46, <18 years). At baseline, physical activity levels were high in both groups (AO 102 (52) vs UC 127 (73) min/day). There was no statistically significant difference in MVPA between groups at either timepoint (post-intervention mean difference (95% CI) -14 mins (-45 to 16)). Uptake of the intervention was low with only 40% (n=21) of participants accessing the web application. CONCLUSION: A web-based application, including individualised goal setting, real-time feedback and motivation for behavioural change, was no better than usual care at promoting physical activity in young pwCF following hospital discharge. High levels of baseline physical activity levels in both groups, and limited engagement with the intervention, suggest alternative strategies may be necessary to identify and support young pwCF who would benefit from enhanced physical activity.

Screening for Cystic Fibrosis Related Complications in the Context of a Pandemic and Altered Models of Care.

Background: Standard of care recommend that patients with cystic fibrosis (CF) require screening investigations to assess for complications. Changing models of care due to the COVID19 pandemic may have impacted completion of recommended screening. Objective: To compare the frequency of screening investigations completed in people with CF before and after the onset of the COVID19 pandemic. Methods: Medical records were reviewed at 4 CF-specialist centers to identify screening investigations completed in the 12-months before and after pandemic onset. Results: Records of 625 patients were reviewed. Prior to pandemic onset, there was between center variability in completion of screening investigations. There was greatest baseline variation between centers in performing oral glucose tolerance test (OGTT); range 38%-69%, exercise tests; 3%-51% and sputum screening for non-tuberculous mycobacteria; 53%-81%. Following pandemic onset, blood tests, and sputum cultures were maintained at the highest rates. Exercise testing, CXR and OGTT exhibited the greatest declines, with reductions at individual centers ranging between 10%-24%, 22%-43%, and 20%-26%, respectively. Return to in-person visits following pandemic onset was variable, ranging from 16% to 74% between centers. Conclusion: Completion of screening investigations varies between CF centers and changes in models of care, such as increased virtual care in response to COVID19 pandemic was associated with reduction in completion of investigations. Centers would benefit from auditing their adherence to standards of care, particularly considering recent changes in care delivery.
