Einleitung

The disease management programme "Living well with COPD" was developed to relieve symptoms and prevent exacerbations. It covers a disease self-management approach, educational topics, lifestyle coaching and physical activity advice.

Future implications should aim to make the intervention easily accessible for a broad spectrum of patients at scalable costs. They need an engaging communication platform which can inform, coach and even listen in between medical visits. The inclusion of a chatbot agent may provide this tailored feedback. Our aim is to investigate the feasibility and effects of a chatbot-based application of "Living well with COPD" on HrQoL in patients with COPD.
Methodik

The CAir-desk enables this interactive delivery to patients at home. It is a custom-built system, consisting of a smartphone, spirometer, physical activity tracker, and air-quality monitor.

A communication channel between patient and chatbot is established via smartphone.

As a primary step, we conducted a feasibility study, investigating the CAir-desk in a sample of 10 patients (5 with Asthma and 5 with COPD), without intervention and chatbot implementation. Afterwards, a sufficiently powered RCT is planned, investigating the effects of the home-based intervention.

For the feasibility trial, a small sample was recruited. Results of this trial were used to improve the CAir-desk and fine-tune the intervention towards the RCT. Primary outcome is HrQoL. Participants randomised to the intervention group will receive a CAir-desk with a chatbot-based intervention programme for 12 weeks. The CAir-chatbot provides several multimodal interventions (e.g. educational content, exercise training).

Participants randomised to the control group receive usual care and a CAir-desk for 12 weeks. In contrast to the intervention group, no chatbot is included.

Schlussfolgerungen

Our work will provide evidence to further develop chatbot-based disease monitoring and intervention in COPD. The CAir-desk enables an evidence-based intervention at home, with individually timed interactions, to support an extended rehabilitation program at scale. Considering the heterogeneous population of COPD patients, our approach is expected to be well accepted.

Bedeutung

This approach may enhance the amount of COPD patients having access to a multimodal intervention. The field of respiratory medicine offers several opportunities to establish similar treatment approaches.
