Primary Care Practitioners’ Perspectives on the Utility of Metabolic Syndrome as a Diagnosis: A Qualitative Study

Background/Objectives: Metabolic syndrome (MetSy) comprises a cluster of risk factors—including obesity, dyslipidaemia, hypertension, and impaired glucose metabolism—that increase the risk of cardiovascular disease, type 2 diabetes, and other conditions. There are close ties between the complications and outcomes of obesity and MetSy. The practical value of MetSy as a distinct diagnosis in primary care remains uncertain. This study aimed to explore general practitioners’ (GPs) perspectives on the utility of MetSy for diagnosing and managing patients in light of evolving concepts in the field of metabolic health. Methods: A qualitative study design was employed, with semi-structured interviews conducted among 15 GPs in rural Western Australia. Participants were recruited via GP networks with convenience and snowball sampling. Transcribed interviews were thematically analysed using Braun and Clarke’s reflexive approach, with iterative coding, theme identification, and member checking to ensure trustworthiness. Results: GPs generally recognized MetSy as a constellation of risk factors that heighten the risk of cardiovascular disease. Insulin resistance was frequently identified as a unifying pathophysiological driver. Nevertheless, most participants did not routinely diagnose MetSy in clinical practice, rather focusing on treating individual component conditions (e.g., obesity, hypertension, dyslipidaemia) due to readily available disease-specific guidelines. Only a minority of GPs actively used the MetSy concept for patient education to highlight interconnected risks and the potential benefits of holistic lifestyle interventions. Paucity of dedicated MetSy management guidelines and uncertainty around diagnostic criteria further hindered routine application of the syndrome in practice. Conclusions: While GPs are aware of MetSy and its broad implications, few use it as a distinct clinical tool. Development of tailored guidelines and expanded educational resources would empower GPs to integrate a more holistic, MetSy-focused approach to patient care.
