Diagnostic and treatment inadequacy contribute to patient morbidity and mortality and lack of adherence to guidelines is a component of this.Aim This qualitative study sought to explore and understand the use of asthma guidelines by primary care clinicians in two geographically bounded regions of Wales.Method Multiple case study design was used. Data was collected using semi-structured interviews with a purposively sampled group of clinical staff from GP practices. Interview transcripts were thematically analysed to produce a detailed picture of practice.Results Asthma care in the studied areas operated as a social network of clinicians who often used guidelines as boundary objects. Practice and local service design was influenced and dependent on regular input from local secondary care providers. Clinicians looked to British Thoracic Society and Scottish Intercollegiate Guideline Network (BTS/SIGN) 2016 guidelines. There was limited use of National Institute for Health and Care Excellence (NICE) 2017 guidelines. Barriers to guideline recommended diagnostic asthma care included: lack of acceptability, financial costs and disempowerment of nursing staff.Conclusion The findings from this study replicate and reinforce the findings of previous work. It is striking and concerning that the thematic outcomes of this study bear a strong resemblance to that which was demonstrated over a decade ago. The guideline-implementation gap in asthma diagnostics will likely persist unless there is significant restructuring, financial investment and greater empowerment of nursing staff in primary care.
