Abstract
- Introduction Chronic breathlessness is a common and debilitating symptom, associated with high healthcare use and reduced quality of life. Challenges and delays in diagnosis for people with chronic breathlessness frequently occur, leading to delayed access to therapies. The overarching hypothesis is a symptom-based approach to diagnosis in primary care would lead to earlier diagnosis, and therefore earlier treatment and improved longer-term outcomes including health-related quality of life. This study aims to establish the feasibility of a multicentre cluster randomised controlled trial to assess the clinical and cost-effectiveness of a structured diagnostic pathway for breathlessness in primary care.Methods and analysis Ten general practitioner (GP) practices across Leicester and Leicestershire will be cluster randomised to either a structured diagnostic pathway (intervention) or usual care. The structured diagnostic pathway includes a panel of investigations within 1 month. Usual care will proceed with patient care as per normal practice. Eligibility criteria include patients presenting with chronic breathlessness for the first time, who are over 40 years old and without a pre-existing diagnosis for their symptoms. An electronic template triggered at the point of consultation with the GP will aid opportunistic recruitment in primary care. The primary outcome for this feasibility study is recruitment rate. Secondary outcome measures, including time to diagnosis, will be collected to help inform outcomes for the future trial and to assess the impact of an earlier diagnosis. These will include symptoms, health-related quality of life, exercise capacity, measures of frailty, physical activity and healthcare utilisation. The study will include nested qualitative interviews with patients and healthcare staff to understand the feasibility outcomes, explore what is ‘usual care’ and the study experience.Ethics and dissemination The Research Ethics Committee Nottingham 1 has provided ethical approval for this research study (REC Reference: 19/EM/0201). Results from the study will be disseminated by presentations at relevant meetings and conferences including British Thoracic Society and Primary Care Respiratory Society, as well as by peer-reviewed publications and through patient presentations and newsletters to patients, where available.Trial registration number ISRCTN14483247.
