Plain English Summary

Background and study aims
Cystic fibrosis (CF) is an inherited condition which causes the lungs and digestive system to become blocked with mucus. It is caused by a faulty gene, which is responsible for controlling the movement of water and salts in and out of cells. This leads to a buildup of sticky mucus which clogs the lungs and airways causing breathing difficulties and lung infections, and the digestive system which affects the way food travels through and the ability to absorb nutrients from it. Most people with CF experience problems with lung function and usually are treated with a combination of physiotherapy and inhaled medications to prevent lung infections and the buildup of mucus that causes damage. Around £30 million is spent every year on inhaled therapy but average adherence has been shown to be only 36%. Data suggest that adherence is better in younger children (71% in under-12s, falling to 50% in teenagers) but of the 10000 UK people with CF (PWCF) almost 6000 are now adults. PWCF who collect less than 50% of their medication cost the healthcare system significantly more in terms of unscheduled emergency care and hospital admission. This study is looking at a new programme which has been designed to help adults with CF to monitor their medication usage, by using dose-counting nebulisers to collect data and send it to a website where it can be displayed. The aim of this study is to find out whether a large-scale study looking at the whether this program is feasible and acceptable to PWCF.

Who can participate?
Patients aged 16 years and over with CF who are within a CF registry and are taking medication via a chipped nebulizer.

What does the study involve?
Participants are randomly allocated to one of two groups. Both groups have a short period of two to four weeks when data is collected through their nebulisers and fed back to the website. Following this, those in the first group are given access to their data so that they can manage their treatment habits. This involves a combination of at least three face-to-face/telephone/email contact sessions with trial staff and using the program independently over five months. Those in the second group continue as normal, whilst having their usage data recorded continually. At the start of the study and after five months, the health and medication usage and behaviour patterns of participants in both groups are determined using the data collected by the dose-counting nebulisers.

What are the possible benefits and risks of participating?
Participants with access to the program may benefit from improvements to the way they take their medication. There are no notable risks involved with participating.

Where is the study run from?
1. Wessex Adult Cystic Fibrosis Service - Poole (UK)
2. Wessex Adult Cystic Fibrosis Service - Southampton (UK)

Scientific title

Development and evaluation of an intervention to support Adherence to treatment in adults with cystic fibrosis: A feasibility study comprised of an external pilot randomised controlled trial and process evaluation (WP 3.1)



Study hypothesis

The aim of the study is to determine the feasibility of conducting a full-scale randomised controlled trial investigating the acceptability of the CFHealthHub intervention.

Study participants will be randomised to either the intervention arm (CFHealthHub) or control arm (usual care). Participants in both groups will contribute adherence data to CFHealthHub but only those randomised to the intervention arm will have access to interact with CFHealthHub to manage their treatment habits. This will be via a combination of face to face (or telephone/email contact sessions) with the trial interventionists and using CFHealthHub as a tool independently between sessions. Although it is anticipated that there will be a minimum of 3 sessions during the follow up period, further sessions will be tailored to each participants individual needs.
